My First .NET MVC Project 1 | Part 4 - Brainstorm from a visual perspective continues

Liming — Thu, 02 Feb 2012 19:35:00 GMT

In my last post, I discussed about the application from a user's profile perspective, today, I thought I will mock up how the site will look like on the home page.

Instead of typing plain text, I thought I would better try out some professional mock up tools and using the product from balsamiq, I'm real impressed. I highly recommend everyone who wants to do a quick & dirty mock up to give it whirl.

Anyway, without further ado, below is what I came up with using Balsamiq such far.

Nothing Fancy.

1. Home menu is where I aggreate most of the stuff

I thought most people would care about reading health or medicare related news on this web site. So I thought why not give it a column and have users share those news with fellow medicare users?

2. Latest Concerns - are bascially questions asked by people on this medicare sites. Again, nothing fancy. I added a few stats to it though, such as

- People also interested, how many answers there are so far, how many tips was recommended to answer this questions, and how many repliers are similar to the current users (by parameters set up by the user. more on that later on)

3. Popular Tips - as the name describes, are tips wrote down by fellow members .

Stats include: How many says, it's a great tip. How many says "YMMV(Your mileage may vary)", etc etc. Exact types are yet to be determined

4. Advertising - As with any sites, you need some advertising to keep it operational right? so I thought, some of the candidates could be insurance companies, pharmacy companies, doctors....

5. Other menus are self explanatory. "In my same shoes" menu though is intended to read/ask/answer everything from people who are similar to the user. Exact detail, I have yet to think it through, but that's the general idea.

Other things to think about.

- Since we are providing advertising, i would like to provide a different kind of profiles for companies and doctors. The reason is that they are very different. They probably will use real names, provide their details, what they have to offer, what type of insurance they accept, etc and in addition, I would like for instances, encourage the doctors to paticipate and address other's concerns and what not. In addition, from fiancial perspective, later on in the future, charge for these type of accounts, run ad campaigns and etc.

- Given companies and doctors are registered, we might provide a separate sections for companies / doctors, so that users can search for them if they want to and on the flip side, we can charge for listing as well.

Liming — Fri, 20 Jan 2012 17:29:00 GMT

Previously, I discussed my inital draft of what entails the applicaiton, as I thought this through, I think it will be ideal to present a visual view of what might be helpful to the users and from here, brainstrom what else need to be added.

I first decided to approach from a personal profile point of view. This is where a user is able to view their own history in regards to issues in Medicare.

How NOT to listen to your customers. Know your job.

Liming — Tue, 17 Jan 2012 14:40:00 GMT

The title might seems strange, you always listen to your customers correct? Customer is god, they should be treated with the greatest respect.

I was reading an article by Mark Cuban http://www.entrepreneur.com/article/222501?cm_mmc=Market-_-Outbrain-_-NA-_-NA, and at first, I was not all too hot about the title "Why you should NEVER listen to your customer", however, after reading the whole article, he wrapped up his points with the following quote

"Your customers can tell you the things that are broken and how they want to be made happy. Listen to them. Make them happy. But don't rely on them to create the future road map for your product or service. That's your job."

This quote is golden and should always be remembered even though the title of the article is a bit misleading.

The issue at hand is do you always do what the customers ask? The answer should be no. Let me explain.

It's too easy to create a product in version 1 where everything you developed is how you envisioned a product should be like, albeit, missing some essential features that yet have to be developed.

Then your customers storms in and they provide their own set of requests.

However, this is where the dangers start.

When customers start to ask about various sets of features, as an entrepreneur, you should ask yourself, who are your targeted audiences? Are these features in synch with your market? For instances, say some people go to Starbucks and might want some pizza as well (I know I know..but it's an example), then as the owner of Starbucks, do you or do you not offer pizza as part of your service? Customers requested, you should listen right?

Well, if you are the owner, you should analyze who is your targeted audience. Starbucks customers are the people who wants to meet briefly, chat, browse web, light meal and be on their merry ways. Pizza while a lot of people like it, it simply doesn't fit the crowd. In my mind, therefore, this should be a request to be denied.

However, offering sandwich is okay, because it's light enough that people while chatting, can still eat a piece of two.

Starbucks is not just about coffee which is over expensive in my opinion, but rather, it's about a culture, an environment, by staying on track of this focus, that's why they can charge your $4 bucks for a cup of hot tall coffee.

As Mark Cuban puts it, you should listen to them, but do not let them define what your business is, it's your job.

Such as you venture onto your future releases and upgrades, it is very important for you to pick and choose the features that make sense for your audiences and discard other features that do not fit your intended crowd. Do one thing and do it well. There is a fine line between a focused, quality product and a diluted - all you can eat buffet but nothing great product.

Lastly, that doesn't mean you should be a d**k to your customers and show them my way or the highway. Be courteous, and be professional.

How your approach will truly make it or break it your company.

Liming — Fri, 13 Jan 2012 16:31:00 GMT

In my earlier post "Identify a market or identify a problem? How you approach your idea makes a difference!", I've described two approaches to a product / service. This post is a reminder of another concrete example of how the two approaches comes to play in reality.

As I discuss further with my business partner Jackson Lin, we came across the example of buying / selling cars. I realized, my type of approach have a serious short coming.

When it comes to cars, I rarely think about in terms of features. Such as

- If they have an advanced navigation system
- If they can lower and higher their body like a range over
- If they can parallel parking like the Lexus
- If they can provide on-star support like the ones from GM
- If they can detect someone in the car like the Volvo
- 0 - 60 mph under how many seconds
- Backup camera
- Heated seats
- Removable seats
- Stereo systems
- Design of the engine compartment, easy/difficult to take things in/out.
- Design of the battery compartment, whether it's easy or difficult to take in / out.

I just care about the following things

1. Reliability If not reliable, then find a more reliable more.
2. Maintenance / Warranty. Does it offer a 60,000 miles / 6 years or better factory warranty. Less hassle and worries for me
3. Price. How much it cost out of my pocket.

The problem with my ways of thinking is that I completely missed out a vertical market where cars / manufactures differentiated themselves by offerings convenience through feature sets. Of course, once my 3 major factors are satisfied, only then I will take a deeper look into the features they offer, however, the point is, that's not how I would approach this product and if I am the head of these motor companies, I probably would miss out a huge potential customer base. I wouldn't have build a Lexus when there is Toyota, I wouldn't have build Mercedes nor BMW when there is Volkswagen Jetta, just because my focus is all in the wrong area (or should I say, limited, as I'm only focusing on one area)

Now, take another look at electrical car. When you tell me, I'm developing a car because it can run on electricity. You are describing a feature change. I'm not that excited. As it's just geeks talking just because they can.

However, when you describe that the gasoline price is sky rocketing. Oil supply around the world is diminishing. The trend of having a car that does not rely on gasoline but rather more depend on the more obtainable electricity, I go wow, a huge market, I see it, I love it.

Now, the same electricty car, if it's in an era where gasonline is plenty, oil price is low, I simply will completely ignore this concept as I see no reason to waste time on it.

Of course, the reverse can also be said for someone who is not happy with the car they have. They want all the features like heated seats, backup camera, kick ass navigation, USB support, wireless internet, electricity based, parallel parking, heart beat detection, advanced airbag protection system, abs, 0-60mph in under 6 seconds, the list goes on and on. Only after they build it, they realized that it has a high price tag, can not offer mileage guarantee beyond 10,000 miles / 1 year, reliability is no where to compete with the likes of their competitors, and scratch their head trying to figure out a market for themselves.

Now this is just an example in the context of building / selling cars. However, to me, it is equally applicable to building modern day software / services.

Shame on Google. The two sides of getting yourself indexed.

Liming — Fri, 13 Jan 2012 15:06:00 GMT

The news just got in. Please read http://blog.mocality.co.ke/2012/01/13/google-what-were-you-thinking/.

In short, a company called Mocality, who painstakingly build their comprehensive business directory in Kenya over the years by investing in money as well as human resources, got hijacked by Google as they PRETENDED they were working in collaboration with Mocality, contacted all the business owners listed on the directory and tried to up sell products and services.

What does it sounds like? Do you own any mortgages? Have you ever received letters from certain loan companies whom knows exactly who you loaned from, your loan number as well as your loan amount and your loan dates, in order to help you "refinance" and lower your monthly mortgage?

This story reminds me of what happened to Yelp. Now, Yelp itself has its own set of problems and questionable practices, however, if you recall a year or two ago, Google gave them this option. Either you let us list your reviews on Google Place (which will make Google Place more powerful and such earns more revenue from advertisers), or we are going to completely take you out of Google search index.

I've had talks over this tactic with others before. Others have a valid point, it's their service, they can do what they want. However, to me it all too much sounds like another form of blackmail. Imagine a police station whose job is to protect the public in their district, comes up to a business and say, unless you give out free stuff to our officers on duty or "donate" your products willingly to our charity events (to raise money for the department) or else we will de-list you from our protection, no 911s, no firefighters, no ambulance. When people rob you? That's too bad.

*Note: Once again, Yelp itself has its own questionable practices and it's really a case of a thief met a robber, but I decide to focus on Google right now.

Now you might say, that's comparing apples or oranges. Businesses pay tax and such they are not using the police for free. Well, my argument is the same. While Google is providing traffic to businesses, however, they are also getting paid by advertisers from having information from these businesses. Businesses is hardly the only beneficiary here and Google sure is not the all mercenary charity, doing a favor for human kind either.

The CEO of Mocality described it the best in my opinion.

"Our database IS our business, and we protect and tend it very carefully."

This statement is the key. So when you build your next start up, you should seriously think about what type of businesses you are trying to build. While getting indexed is a good thing especially when you are a small company, you are using Google's influences to get to your potential customers, consider two sides of the same blade.

Anyway, I digressed. In Mocality's case, it's not just that. It also involves fraud, as Google this time went a step further. Cold stealing customers while pretending to be working in collaboration with Mocality, to gain people's trusts.

In my honest opinion, all they had to do is ask Mocality, if they may use their index and use it to sell their services. Hell, just use their services without telling any customers they are in collaboration with Mocality, Google's reputation itself should have been convincing enough.

*Shake heads*

Identify a market or identify a problem? How you approach your idea makes a difference!

Liming — Thu, 12 Jan 2012 15:50:00 GMT

The other day, my business partner Jackson Lin and I had a rather interesting discussion.

Background
------------------------------------------
It all started by an article discussing the differences between Tumblr and Wordpress, how Tumblr was able to build a service that looks similar to Wordpress and yet, able to build a huge base of audiences to themselves.

I started by expressing that the reason in my point of view is that they identified a crowd, a market who are looking for "light blogging", an environment where NOT all piers create long postings that seems as if they took an hour to write, an environemnt where it's fun, light and easy to record something quickly and share with their friends as well as strangers.

In my opinion, they identified a market, came up with the idea of Tumblr and then started to think about how to tweak a blogging service to fit this market.

Interesting enough, Jackson expressed a rather different view, however equally as valid.

Jackson expressed that Wordpress platform itself is not as "friendly" of a service to a lot of people. It's not as easy to use and it's more intimating to beginner or light blogging users. The workflow / UI in a way, forces you to think about what to write, how to write and definitely try to write well. Tumblr recongized that fact and build a friendly UI/Workflow where it's extremely easy to blog, you can quickly categorize what type of posts you want to blog, might it be Text, Pictures, Links, Movies or whatever. By implementing these critical features, it succeeded in pulling in their unique base of audiences.

In Jackson's opinion, they identified a problem in an existing software / platform, by fixing the problems, it generated a new base of users that is both unique and loyal to its services.

Approaches
------------------------------------------

As we discussed, we realized that we've always been this way. Jackson would always find one services or two and identifies the problems with them, how it would be nice if they did do or did not do certain things, how a service failed because they provided too much or provided too little of this feature or that feature. He wants to build an alternative service that fixes these problems.

While I, most of the time don't think too much in terms of " features & problems". When you tell me there are people and a lot of them are looking for certain things or if there are a lot of people are unhappy of a certain service due to a range of things? I see a market. I get excited because there is a potential for us to build something and grab their attentions. I want to build an alternative service for these people.

Solutions and Problems
-----------------------------------
Jackson and I often would agree on this one service that we both want to build, however, we never realized that we wanted to build for two different reasons. Without realizing this, there are problems when it actually comes into implementation.

Jackson would build a product from feature perspectives, and we would discuss what features to put it, what to get rid of and what to improve. Throughout the process, I would think of features as well that are super cool and make the software more "powerful". In my mind, the more, the merrier, the more powerful that is, the happier my customers will be..

The problem is, we would both go off the rail and forget completely the reason why we wanted to build it in the first place.

Jackson would explain the product from the feature perspectives, what it offers and what it does. If potential customers, whoever they are like what they see, they then would form a unique customer base themselves.

Me, on the other hand, try to satisfy my audiences as much as I can. As long as our competitors don't offer it, then we will try to implement it. I want the market. I try to make it appealing in all different types of scenarios. The problem is however, the product will end up loosing its focus,to a point where customers can't identify what is the software EVEN THOUGH it offers all the features they need. When customers can not associate with your service, they simply don't buy it nor join it no matter how powerful it is.

Lesson and Conclusion
-------------------------------
The lesson here is, know your audiences and knows yourself, what is your identify and who you are. Don't lose your focus and try to do a little bit of everything. Even if you mange to do everything well, but if you can't identify who you are, your customers certainly won't be as well.

My First .NET MVC Project 1 | Part 2 - Brainstorm Application and Use Cases

Liming — Fri, 06 Jan 2012 18:32:00 GMT

Previously, I wrote a post titled "American Healthcare - A maze needed to piece together by seniors", I realized that it was somewhat difficult to piece together the information out there on the web. Maybe it's due to a lot of Seniors are computer illiterate or simply there aren't that many young people willing to spend time into helping them.

A simple search of "Medicare forum" on Google, did not turn up any place truly helpful. Let along, search for Medicare information useful to immigrant patients who still prefer reading in their native languages. So, let's humor ourselves this time and think about a useful website that can assist Seniors shall we? Not really a sexy idea, but hey, we are trying to brush up our .NET skills with a sample application aren't we? Might as well serve some purpose.

Technical requirement is mentioned in [Project 1 | Part 1 - Technical Requirement].

First Draft : Jan 06, 2012
==================

Goal:

To create a website / application where Seniors (and their kids for that matter who are helping them) to be able to plan out their Medicare, connect with other Medicare users who are in similar situations, get ideas and learn from others who have ALREADY been in their shoes, get tips, to-dos and discuss Medicare / insurance / doctors / patient care related issues.

Basic Requirement

1. Users can remain anonymous - Let's get this clear first. I simply don't dig the Facebook / Google + policies. Medical information is private and some questions would be embarrassing to ask in public under your real name.

2. Users do not have to register in order to view the content. At anytime while viewing however, we give the users the options to fill out some information to help them find others who have similar situations, such as age, with spouse, no spouse, spouse's age, zip (some insurances are only offered in certain areas), currently have traditional medicare or medicare advantage (Part A + Part B) or Part D, etc

3. To ask questions, user need to register and if the user was an anonymous user, all previously entered information while filtering the information will be auto transferred as part of registration process.

4. All questions will be able to have multiple tags such as "Medicare", "Part D", "Enrollment", "Dis-enrollment", etc

5. All questions have the option to seek specific audiences such as

- age 64, soon to be medicare users
- age 65+ users
- age 65+ users who have medicare part D
- age 65+, Part D, living in Virgina
- speak Spanish, or Chinese or etc.
- Income Level - Under $10k, under $20k, etc.. As it does have an impact for people with Mediaid (no that I understand the details of it)
- Existing Conditions - Such as Glucoma, High Blood Pressure, Diabetes, etc etc etc.
- Professionals such as healthcare provider, agent, etc

6. People matching the quarteira will see a list of questions targeting them, in addition to a separate section of an up to date complete list.

6. People viewing the questions can mark a question as "I'm in the same shoes" to get notified of the answers

7. People viewing the answers can mark "I agree with this comment" or "I disagree with this comment".

8. People answering questions should be able to submit "Google" / "Bing" search engine keywords they used to get their answers from to help other people.

9. Due to the nature of laws changing every year, it is important to list questions and answers relevant to the year in question. All questions / answers will be sorted and highlighted clearly to indicate if it's current year or past year.... and users are able to filter questions/answers based on the year as well.

10. In addition to questions/answers. you are able to find / add people who are similar to you by your demographic. Read their questions / answers

That's it for now. I will have to brainstorm some more and revise in the next few days before I narrow down the scope and what else to add / remove.

To be continued...

American Healthcare - A maze needed to piece together by seniors.

Liming — Fri, 06 Jan 2012 14:59:00 GMT

First, let me note down a bit of a background.

My parents are over 65 and they are on Medicare. Due to the language barrier, I had to chip in and lend a helping hand. It's not that they can't speak English, but to navigate through the maze that is Medicare, it seriously takes hours and hours of conversations with agents and customer services, therefore, it's important that they don't misunderstand any details.

Now, their basic requirement is simple. They are looking for private insurance companies who offer Medicare packages or sometimes called "Medicare Advantage". However, they do not want to pay any more premium in addition to what they already paid to Medicare. This means, we had to search for $0 premium "Medicare Advantage" plans. We found it and it was Humana "Medicare Advantage" - HumanaChoice Regional PPO which covers Part A and Part B of the Medicare, with no prescription drug coverage. In the profession of Medicare, they call it the "MA" plan.

**Note: Medicare Advantage plans are regulated by the Centers for Medicare and Medicaid Services (CMS or Medicare) and implemented by private insurance companies (such as Aetna, Humana, and United HealthCare).

The confusion started when we wanted to look into the drug coverage or Part D of Medicare (an optional choice). In order to enroll into Part D, you have to make sure that ever since you were eligible, you never had a period of more than 63 days (I think) of gap in coverage. If you had, then you will incur a penalty at the rate of 1% of national average premium for the time you did not have coverage FOR AS LONG AS YOU CONTINUE the coverage MONTHLY. Did you understand that? Read it again! (Source: https://questions.medicare.gov/app/answers/detail/a_id/2255/~/late-enrollment-penalty-(lep) )

For instance, national average premium for 2011 is $31. 1% of $31 is $0.31. If you had no coverage for 24 month in previous years, then you have a penalty of $0.31*24(month) = $7.68 penalty. IMPORTANT. This $7.68 will now add to your monthly premium for as long as you continue the converge. IT IS NOT A ONE TIME late payment!!! If you premium is suppose to be $15 a month, that means now, you will have to pay $22.68 a month, every month, every year from now on!!

Okay. Fine. Better to join early than late or else, the monthly premium penalty will increase month after month and year after year. So we chose Humana Walmart Preferred RX Plan for prescription drug coverage or what the professionals called - "PDP" plan, and this is when all hell broke loose.

You probably would figure by now, that okay, I have a "MA" Plan that is HumanaChoice Regional PPO, and now a "PDP" plan that is Humana Walmart Preferred RX Plan, I'm good and covered completely in Medicare Part A, Part B and PartD correct? NOT SO!!!

After hours of conversation and navigates through a maze of representatives, we found out that there is a rule from Medicare, not Humana, that you may not enroll into a standalone PDP plan without being dis-enrolled from a MA plan or a MA Plan with prescription drug coverage (or what the profession calls a MA-PD plan). In our case, by enrolling into a standalone PDP plan, without any acknowledgement, Humana auto dis-enrolled my parents from their MA-plan!!

The end result is now they are back to traditional Medicare (the red and blue card) + a PDP plan.

From this lesson, I realized the following

1. We should have known this rule, but then again, there are SOOOO many.

2. Humana should have given us a huge warning that states - "Are you sure you want to enroll into the PDP plan? If so, you would be dis-enrolled from your Humana Regional PPO medicare advantage plan due to regulation!!?"

3. Medicare system - Made by lawyers and politicians. Way too complicated.

It's a learning experience and it truly makes you think about the innovations that is desperately needed in the Healthcare industry.

Ready....Go! My first .NET MVC application Project 1 | Part I - Technical Requirement

Liming — Wed, 04 Jan 2012 20:26:00 GMT

I have a simple ideal application for learning MVC and below is a list of the technical requirement I wish to achieve

1. Use MVC 3 / C# (MVC 4 looks like it's still in developer's preview, so we'll skip that for now)
2. Use Entity Framework 4.1 (See what's good and bad about it)
3. MySQL Server
4. Master Page needed using Razor View Engine
5. Theme is a must
6. Internationalization / Globalization is needed. (driven by database, no resource files)
7. Need Restful API with authentication enabled.
8. Ajax based. JQuery with (either backbone.js or knockout.js). JQuery Template needed.
9. Webgrid helper - use that to generate the default grid upon loading. use JQuery/Template for manipulation.
10. All form fields have to be validated server side with globalized error messages.

The application itself is a somewhat simple website. Hopefully it will give me insight into the various technical aspects needed to build a modern web application.

A Programmer's New Year Resolution

Liming — Wed, 04 Jan 2012 18:33:00 GMT

Really, it never works, but I have to try.

ASP.NET MVC (3/4) is something I have to get on board this year. Learn it well and converts all my .NET 2.0 applications this year and have them up to date.

I'm still somewhat sketchy on the lambada expressions (Yeah, I'm really behind now) and whatever is new in C# 3 / 4. This will be a pretty exciting new year.

In addition, mobile development has became main stream and I predict that in the future, mobile development will become an essential skill required by application programmers, after all, what good is it to have a website but not have a native mobile app along with it? This is another goal I will try to obtain this year. First and foremost, I will focus on Android platform as I'm equally experienced in Java and learning Android development will be the best place to start. Second, comes with Windows 7 Mobile. IPhone will probably be my last just because I need to buy a mac to develop on it (or I could hack a PC to run Mac OS. Tiring process....)

Lastly, I plan to blog more often whenever I learn something of interest along the way.

Anyhow. Below are the resources I've found so far for references. Happy New Year everyone!

Design Change and the Impact on Products

Liming — Fri, 23 Sep 2011 18:51:00 GMT

It's funny how a simple design change can impact your product.

I've been a loyal Yahoo Mail customer for years and years, and to me, email is email. If I don't have obvious reasons, then I don't see a point of switching. Recently, after accidentally clicked the upgrade option, I was upgraded to the new Yahoo mail. Before, I always had the option to switch back to the classic version, however, this time, that option is no where to be found.

I can see why Yahoo wants everyone to upgrade to the new email interface. Ajaxed, resembles outlook, gives Gmail a little competition, so on and so forth. However, there are two features that I used the most are missing in the new email interface. I really want to stay with the new GUI, however, with those missing features, I simply can't manage it.

On top of it, because I couldn't find a build-in way to switch it back to the classic version, for a short second there, I almost wanted to abandon my long used email address.

The missing features are "Read all unread" emails and "From Contacts" emails.

Over the years, I signed up a few services that I want to look from time to time. If they are interesting in the subject line, then I take a look. Otherwise, I delete them. Sometimes, I'm out for a whole week and I will be back with 40-50 emails waiting. I typically pick the messages from family members and friends first (and such I used the feature "From Contacts") and when I'm done, I click "Read all unread" messages, give a quick scan, nothing interesting? Delete them all. Simple and easy to manage. No need to setup custom filters, no need to mess with tags/flags like in gmail. I was a happy camper.

With the new Email Interface, the only thing I could do was "Sort by Unread messages" which makes unread messages appear on top. However, to delete them all, I have to click each check box one by one individually, all 40-50 of them every time as oppose to "Check all". That was just too much.

Luckily, since I figured the new UI is javascript heavy, what if I turn off Javascript in the browser? Tried that, and voilla, Yahoo gives me back the option to switch back to the yahoo classic. Enable Javascript again, I'm back to my dearly loved (but somewhat lacking) classic interface. Within the next 2 minutes, I deleted 100 unread emails from different services and other non important messages from friends like jobs, jokes and the mass bcc kinds.

It makes me really ponder on the design decisions a company makes on their product. From this experience, as you can see, as loyal as I am to Yahoo mail, when a new feature comes up and takes away a really small but important feature that I absolutely need, that's all it takes to scare away the existing customers.

It's interesting that this experience of mine coincide with the release of Facebook Profile change. A lot of people love it, a lot of people hate it. It's true, you can never make everyone happy, however, a big design change such as the new profile "Timeline" feature, I really wonder if that will take more users away from Facebook than attract more new users. With G+ on its heels, to me, retain their existing loyal users are more important than attract new fresh bloods. This is a gamble that is unnecessarily risky..

Random observations from a random experience, life goes on, eager to see what other exciting things companies have for us in future.

Await .NET 4.5

Liming — Fri, 16 Sep 2011 18:10:00 GMT

I have been stuck on the .NET 2.0 bandwagon for the longest time.

During the development in the past few years, I have watched Microsoft giving birth to .NET 3.5 and .NET 4.0, the features came out of them such as LINQ, LINQ to SQL, Entity Framework, Enterprise Library, MVC and others. I read them, I had an idea they existed, but because I was focusing on improving the product I'm making, other than MVC framework, I simply haven't had much time to dive into the details from most of them, overtime, I got seriously behind the curve.

Lately, my interests have been largely focused on asynchronous programming in.NET as I'm concerned of the performances that the traditional synchronous operations have on the servers. While asynchronous programming has no direct impact to the end users per say, however, it is absolutely vital to end programmers such like me to leverage it, get the best values out of the CPU / CLR Threadpool and as a result, maximizing the full capabilities of the hardware and such delivery a better product to the end users. I'm glad .NET 4.5 took an emphasis in this area.

In addition, real time live updates in the past has been nothing short of difficult. The only solutions you had were to ajax poll on a regular interval or implement your own comet solutions which involves long persisted connections with asynchronous programming implemented on the server side. This effort itself is not for the faint of heart and I'm glad that it too has been addressed in the upcoming .NET 4.5 with the WebSocket namespace.

I highly encourage anyone who are in the same shoes as me to read over the changes (http://www.asp.net/vnext/whats-new#_Toc303354469) and get a general idea of what's coming, dive into it and prepare for your future developments.

Overall, I think I will finally take the leap and jump off the .NET 2.0 / Web Form bandwagon. .NET 4.5 still have awhile before it can be released, meanwhile, migrate to .NET 4.0 is my top concern. Once we are upgraded to .NET 4.0, switching to .NET 4.5 will have a less impact as oppose to directly switching from .NET 2.0 to .NET 4.5

One thing though, I'm somewhat disappointed to learn that the Entity Framework still does not support the asynchronous model. To fully leverage the CLR Threadpool, Microsoft seriously need to put some energy into this area and gives us a full stack we can really use.

Lotus Seeds

Liming — Thu, 08 Sep 2011 02:17:00 GMT

It has been ages.

People who've lived in Asia loves to eat this delicacy. They are lotus seeds and in China at least, it's only available in summer time.

They are tender and they are mildly sweet, a summer must have when you wanted to chew on something.

Sigh.

Touchpad Minus. I want one

Liming — Tue, 23 Aug 2011 15:38:00 GMT

Just went over to Techcrunch and read the article titled "Dear HP: Please Keep Making Those CrunchPads! Er...TouchPads", I have to say, I can't agree with it more!

Over the weekend, due to the $100 price tag, I was running around like maniac attempting to secure myself a touchpad or two, or three or four. Hell, if they had 8 left, I would've bought them all.

The reason is, I really just wanted a simple device to read yahoo/gmail, read CNN, Techcruch, Mashable, New York Times, chat with friends using GTalk or Meebo, watch movies (yes, that means flash) and skype. NOTHING else. I don't need Microsoft Office on it, I don't need to play games on it (but if you offer it in the browser, I'm fine with it), I don't even need to take pictures or photos on it. If I need to take notes, I'll head on over to EverNotes. If I need to take a picture, I'll pull out my phone or camera for it. If I need to do anything more serious, then I'll head over to my computer desk, upstair or in the basement, 3 workstations, 1 server, 2 different laptops, I have more than enough to do serious stuff.

So see, with $100, if you are able to give me all that and then some, why not? I will not only get one, I will get a couple of them because for instance, my mom is completely computer illiterate, it will be much easier to have her use it then learning a PC. I can take it with me while taking a #2 (excuse my use of number), use it as a digital picture frame / find recipes while in the kitchen, so on and so forth.

I know there are some cheap tablets on there, but you know, either I can't trust the brands or the review came out bad, really bad. However, for a brand like HP backed with WebOS, mentally, I'm just more willing to spend the $100 because even if it came out not as ideal, I trust the company in the future will back it up and improve it.

Too bad, this time, HP proved me wrong and pulled the plug on WebOS. I really wanted a Touchpad Minus.

Btw, if anyone has an extra Touchpad for sale, I'm willing to pay $150 for it. Thanks :)

Amazon AWS Explained - In Layman's Terms

Liming — Fri, 19 Aug 2011 20:51:00 GMT

So my business partner Jackson Lin and I have been looking into a more reliable hosting option.

Our traditional "shared" hosting has been giving us some heart burns here and there. Throughout the past few years, we discovered a few distinct disadvantages as we grew our small start up company, things such as

Being shared, at times, the website is slowed down to a crawl
Have no control over the serve itself
Can not install our own software
Being an ASP.NET shop, "shared" hosting does not grant us "Full-Trust" permission. Limits our options (can not use the PayPal SDK for instance)
Can not dynamically increase our server load abilities
Unreliable email services (it's fine now, we changed to Google Domain for business)
etc

While traditional hosting company can and will work with you if your website is down or needs more capabilities, the downtime and the time it takes to bring the website back up with a more beefed up machine, it takes way too long and the experience is less ideal.

Amazon AWS and Microsoft Azure for all intends and purposes, seem to address all of our concerns and such far, Amazon AWS seems to be cheaper of the two and so we tried to dig in and find out more about it.

The issue is? My god is it complicated!! We were thoroughly confused with the myriads of options and jargon. So after some research, I'll try to explain in layman's terms to the extend of my limited knowledge.

Amazon AWS - It's basically Amazon hosting. AWS itself doesn't mean anything. It represents the entire ecosystems of everything Amazon has to offer.
EC2 - They are basically the "machines" amazon has to offer to you. Windows or Linux. Though, they are "virtual" machines instead of a physical computer you can see and touch. For commoners like us, it doesn't matter much. We'll just consider them as real machines. It's easier to wrap our heads around.

For Microsoft Windows machines, , they normally come with Windows server (2008) equipped with IIS and .NET framework already installed. So we don't have to worry about server license. That's good.

On these virtual machines, they normally come with 1.7gb of memory, 1 virtual core with 1 EC2 Compute Unit (like single core cpu machines) for small instance with 160 GB of disk space, which is good, but we probably wont' be using it (I'll explain it later).

What's good with these EC2 servers? In case of sudden spike of traffic increase, you can add 1 or more of the same type of machines on the fly (which will cost the same price of your existing one) and at that time, you can enable "Load Balancers", so instead of 1 server handling the traffic, you can have 2, 3, 4, 5, different servers to handle them at the same time, divide up the traffic. When traffic dies down, then you kill those extra instance (which is charged on a per hour basis), so you only have to pay when your traffic is super jammed.

The trick here is that cost. Instead of 1.7 gb of memory per machine (Small Instance), and you end up with 6 instances to handle the traffic, you should calculate that and see if you should increase it to have a large instance (7.5 GB memory running on 4 cpu) or extra large instance (15 GB memory with 8 cpu). They are more powerful and probably 1 single machine can handle x amount of small machines.
Regions and Zones - Regions is sorted like where Amazon's Data center is. In west coast, east coast, or somewhere in central U.S.A They also have regions in Asia like Singapore. Basically, in case some big disasters happen, your data is safe. Normally "Region" is just one big facility in a city, like an office park if you will.

Zone is then somewhat like individual buildings in the park. Say in East Coast Region (Northern Virgina), they have building 1, building 2, building 3, etc etc. So you can choose to have your server be served from multiple buildings, and/or multiple regions (East coast and west coast).

It's like you are trying to design for Armageddon, in case building 1 is on fire, your data is still served from building 2, so on and so forth. If ALL the buildings in the office park in Virgina (east coast region) is wiped out due to Zeus's lighting, you still have options to switch to the west coast.
EBS - It's basically the storage. Think of it as a network drive in your house, an external hard drive. Now I mentioned earlier that you should not depend on the 160GB on the virtual machine. Why? Because if the virtual machine crashes or a patch is need to be applied to the Virtual machine? It will be temporarily shut down and your data stored on there COULD be lost. EBS however is simply a network hard drive, so the data will always be there.

You can shut down your instance (in case of failing), create another instance with your webserver and asp.net files, point the existing EBS back to the new instance, bang. you are back online.
S3 - Also a storage. Now this is a bit confusing comparing to EBS and basically from my understanding, EBS is faster to read and write but with the limitation of HAVE to be in the same zone as where you web server is. Its' a network drive after all, in your house.

S3 is more like a hard drive on the internet. Similar to services like DropBox if you know what it is, where it's not confined to any particular zone. It's up in the "cloud" and can be accessed and shared from anywhere. Disadvantage? it's slower as it's crossing the "internet", not like EBS which is more like a drive in your own house. Another disadvantage? It's a bit more expensive than EBS. 15 cents per gb compare to 10 cents per gb of EBS. But hey, you can store your files in the "cloud" and retrieve from the "cloud", anywhere, anytime, even from another hosting company. EBS can not.

So when it comes to decide where do you want to store your files. Its' a matter of deciding do you store the file in your house or out on the "internet".

General consensus is that you store and install "software" like Database, search indexes on your EBS for fast access. And for static files, public files such as images, css and what not on S3 (which very conveniently, can be retrieved say from a website hosted elsewhere)

If you want to have long term backups, you can then take a snap shot of your database (scheduled) and other type of search indexes on EBS to S3 for long term storage. In case god forbidden, EBS fails, you can quickly restore back from s3.
Amazon RDS - Basically, it's a virtual server admins for database. What it does is that it handles backup of you database (by default once every day) and offer ability to restore your database in case of disaster. In addition to other services such as replication.

*Note, currently it's only available for MySQL.

Now, what is replication you ask? There are two types of replications

One is called "Simple read only replication". Meaning, they will create a mirror SLAVE instance of your database (two slave, three slaves, etc) and they are read only. So every time you save something into the master database? It'll auto replicated to the SLAVE instances. So what you can do is to have your application to read primarily from the slave and allocate write to the master. So for instance, your website have 1000 contributors to contribute news. But 1 million "view" consumers. You probably want to have all reads come from the mirror instances (to reduce load) and RDS helps you to distribute that. Downside? They are read only and whenever anything writes to the master, it MIGHT NOT be immediately replicated to the slaves. The fact it's in the same zone as your database. Meaning if you database is in building 1 of Northern Virgina, your slaves are in the same building. When building 1 say got bombed? Oops. your data is lost, both the master and slave.

Another type of replication is called Multi-AZ replication (which costs additional money). What this does is that whenever a master writes to the database, it's copied IMMEDIATELY to the slaves. Not only that. The slaves are in multiple zones within your region. Unlike simple replications which is in the same zone within the same region. In case of fire or air conditioning failure in that building fails, meaning "Building 1 in Northern Virgina is on fire and bombed", your data will be still available from building 2 and building 3.

So that's the overview in layman's term. As you can see, there are some very very annal people out there when it comes to hosting. Their ideal setup is probably prepared for the end of the world, but on the Internet? You never know. When people pours in, if you are prepared for it, it's heaven. If you are not? It's hell.

U.S Postal Service - Is benefits law dragging it down?

Liming — Fri, 19 Aug 2011 15:42:00 GMT

The short answer is yes for the time being, and no for the long term and the future.

CNN reports - "Is benefits law dragging down the Postal Service?", the U.S postal service is loosing billions of dollars a year and about to lay off tens of thousands of workers. By the way, did you know the U.S Postal Service employs around half a million people?

However, in my honest opinion, U.S Postal Service should really look into their management and brings in leaders with visions, seriously manage and treat this "company" as a for profit entity!

With the technology, the social media and competitions around them, if you don't innovate and streamline your organization, you will be a thing of the past!

Just take a look at all the publishing companies, newspapers and magazines, all of them are fighting and fighting hard for their chance of survival, why should U.S Postal Service be an exception? Just because "delivering mail" is too boring to innovate? and who says you can only deliver mail???

- Ever thought about smarter advertising?
- How about a better mail client? one that rivals Gmail? Everyone gets an account.Free accounts, based on their zip, will have localized advertising from your local partners. Upgraded accounts will have none. hm?
- A Craiglist type of service where local citizens can post listings or sale items?
- Partner up with local police to provide a comprehensive site of criminal activities or local news, registered sex offenders?
- Traffic report? Social Local? Eat at Zip x? Latest local developments?
- Groupon type of collaborations with local businesses?
- TaskRabbit -ish services?

C'mon, all of these can draw a significant amount of advertising revenues and maybe subscriptions.

These ideas if done right will easily bring lots of revenues to the organization. With all the offices and mailmen/women at your disposal, think!!

*Side note. I hate Fedex! Especially at the package pick up center. Multiple times, I wonder, why I pay them to treat me like I'm invisible. Believe it or not, U.S Postal service actually have better manners.

Ladies and Gentlemen - Looking for rich singles?

Liming — Fri, 19 Aug 2011 15:26:00 GMT

CNN Money Reports - "Best Places for the rich and single".

Now I'm not sure how accurate the list is as I personally have not been to all the places mentioned, but Ranking #2 - "Tysons Corner, VA", is probably a good bet for all the single ladies..and gentlemen alike.

The articles fails to mention that other than the many private sector jobs being offered around there, a lot of those Northern Virginians who visit Tysons often (singles) are probably contractors of some kind who sucks in at $60, $70, $100+ an hour from some government contracts.

You really do have a higher probability of picking up something worth awhile.

Dear Palm, not again!

Liming — Thu, 18 Aug 2011 20:55:00 GMT

I clearly remember when I first owned a "smart" phone, the Palm Treo 600, my business partner Jackson talked me into it. It wasn't cheap either. I remember $300 per phone?

I was not and still am not a big gadget fan. While Jackson and my other friends who were using Palm to improve their productivity, download apps and what not, I wasn't one of them. I just used it as a regular phone. I barely even used any text features. I just didn't like the fact I have to sync with my computers and all that. Too much hassle.

Sometimes during the last 8 month, after I started using Sony Ericsson Android, I started to like it a lot. It's my second "rich" phone or should I say my first "smart" phone, but the experience is vastly different. So I talked to Jack and compared the current smart phones with Palm, I remember I said, "You know Jack, I think the current phone market works because they have a good developer ecosystem, as well as the phones are internet connected, you can download the apps without hooking up to a PC!" . Jack responded "You know, Palm model blah blah could do that right? and Palm had a huge base of developers too", I was shocked, only then I realized how "forward" thinking the Palm series were, but it was a little too late. Palm never was able to reach regular users like me who are non gadget lovers. I asked Jack, "Is it because of its marketing? I mean if they advertised it like how Apple marketed their IPhone and their app store, I'm sure at least I'd been aware of it!"

Ever since Palm was bought by HP, I have been following up on the release of HP Touchpad. I thought to myself, with those talents? I'm sure they can come up with something that'll rival the IPads and Android tablets. From all the reviews I've seen on Touchpad, I think I really liked it. For the first time, I'm actually thinking of getting a gadget like the tablets without anyone to persuade me into it.

Too bad, reading Techcrunch today, titled "It's Official: HP Kills Off webOS Phones And The TouchPad", it's dead. It's dead before I can realize its potential.

I have to ask, and this applies to a lot of products out there, is it the product or is it the marketing or is it simply the wrong timing???

Talent waste in the Silicon Valley

Liming — Thu, 18 Aug 2011 20:06:00 GMT

Reading today's Mashable post, titled - "Can Google+ Challenge Facebook for Social Gaming Dominance?", I can't stop thinking about the one issue that has been bugging me for a long time, that is the talent wasted in the competition between the social giants.

Maybe that is because I'm coming from the enterprise software background, it's just that with all the capabilities that these giants have in their arsenal, to be competitive and popular, their focus have turned into social gaming. How many talents are being reallocated to make this happen? Are those top notch developers enjoying their skills being used there?

I don't mean to dis on the game developers. I'm sure you are all top notched in your own rights. I'm just thinking how many non-game developers are being reallocated in order to make this happen when these same developers could focus on something else that can be more productive and such improve everyone's life? I guess that's why whenever I see niche startups who focus on things such as better search (duckduckgo), education (BeatTheGMAT), Travel (GogoBot), Content Curation (Trap.It), note taking (Evernote), questions/answers (StackOverFlow) and too many others to mention, I get more excited than say.... yeah.. games.

I guess Google is big enough to sacrifice a few of these developers in the grand scheme of things. After all, they have many more talents who are working on something else.

I'm just saying.

Scared bunch or something else? What the heck are the banks doing with all the money?

Liming — Thu, 18 Aug 2011 19:50:00 GMT

According to CNN Money - Home sales take a sharp turn down, home prices are at one of the lowest point since 1970, but due to strict loan requirement, a lot of qualified buyers are prevented from getting a loan.

My questions to the banks are what the hell are you guys doing? When there are too many unqualified borrowers, you lend them carelessly. Now with federal assistance and the truck load of money the government is giving to you, you turn your back to qualified buyers because you are "scared", can you guys do anything right? First your wreck the economy and then you prevent it from recovering!

"While the struggling housing market has made buying a home increasingly affordable for consumers, many can't get financing from lenders to make purchases and therefore help the market recover, said NAR chief economist Lawrence Yun."

"Affordability conditions this year have been the most favorable on record dating back to 1970, but many buyers are being held back because banks are offering financing to only the most highly qualified borrowers, ignoring a large share of otherwise creditworthy buyers," Yun said".

Further more

"Contract failures, largely caused by declined mortgage applications or appraisals below the negotiated price, were unchanged in the month. But 9% of realtors said that a contract was delayed in the past three months because of low appraisals, while another 13% reported that contracts were negotiated to a lower sales price because an appraisal came in below the price that had initially been agreed upon."

Back @Blogging. It's been a long time

Liming — Thu, 18 Aug 2011 17:06:00 GMT

Wow, it has been 8 month since I blogged. It's been a long time.

In the past 8 month, a lot has changed in terms of my social behavior. For the longest time, I have resisted social media platforms such as Facebook, Twitter, Tumblr and such. I simply didn't see a need for it and used this blog as my main source to broadcast my thoughts.

8 month ago, while discussing the roadmap of the future Jumptree, we wondered, if we missed any important aspects of the "hot" social media tools and decided that the best way is to actually try them out, use them and see if there are any useful ideas that will be helpful. Added to the fact, back in December, I was still using one of those old and basic cellphones, so I was definitely not up to date on the social media bandwagon so to speak.

Long story short, I got myself a Sony Ericsson Android, started using my Twitter account "@liming22031", started posting on the almost forgotten Facebook account, tumblr and lately, with Google plus, I can say now that I have a good grip on "social media".

Here is what I discovered as a complete newbie to social media so far

- Twitter is useful and chaotic at the same time. Sometimes I'm not sure if I'm using it as just a RSS feeder or a communication platform, but I was impressed with how easy it was to reach out to companies' customer services department through Twitter. The only two times I wrote about my complains, both of them were addressed within an hour or two. But the problem is? After 8 month of mainly consuming Twitters, the user experience simply weren't that great, chaotic is the only way I can express my feeling towards it. I can't filter messages, I can't group messages, I can't follow / save #hashtags, awkward ways to group people I follow, hard to keep track of replies, the list goes on and on. Seriously half baked imho.

- Facebook, well, I guess it's good for what it is intended for, but I was bombarded with useless informations that my friends post (don't mean to offend anyone), I simply did not feel comfortable to post my "serious" thoughts on there, just a general feeling that my posts will be out of their place. My wife use it more often that I do though, to see pictures from her friends which in my opinion, most of them should have kept them private, such as "hey everyone, see what my husband bought me for my birthday!". Seriously? Anyway.

- Tumblr. This tool is a bit confusing to me till I see that it's a way to connect blogs, but other than that, the goal is somewhat ambiguous to me. I didn't return to it that much to be honest.

- Google Plus. I have to say out of the eight month of experimenting, Google Plus caught onto me the quickest and stayed with me the longest. For the first time, I felt comfortable sharing with friends, solved my problem of easily share my photos and take photos to share, group messages. I still mainly consume posts from tech bloggers, but I find myself share personal posts with friends more often than any other platform. Having said that, Google plus lacks in many other areas that at this stage, beta probably is the right stage to describe it.

Overall, Twitter, Google Plus is here to stay with me for now and blogging is still necessary. The good side to all this, is it really opened up my eyes on the opportunities out there and it helped me to shape my vision for not only Jumptree in the future, but also probably a strategic changes in terms of resource allocations.

The next one year will be exciting for all of us.

Btw, I apologize to all Jumptree customers. In the past few month, I developed a back pain that lasted two month followed by a seasonal flu, and with a bit of distraction researching on social platforms, it took a toll on my team and it resulted in the unnecessary delay of Jumptree V1.5. I'm seriously taking this into account and make sure the way we manage the team will get better and be isolated from my personal issues.

GroupOn, Is it a Win/Win in the short term but Lose/Lose in the long term?

Liming — Fri, 03 Dec 2010 09:16:00 GMT

With recent rumors of Google will be purchasing Groupon for 6 billion dollars, the first thing that comes to your mind is, really? Does it worth that much? I mean Google bought it, it must be good. Google knows how to make money!

In GroupOn’s own words “Groupon uses collective buying power to offer unbeatable prices and provide a win-win for businesses and consumers”. In another words, what Groupon seems to tell you is what we already know, i.e, “Buy More & Save More”. I mean that’s what Costco/BJ does right? So are the wholesalers. They sell cheap but sell by mass, they make up the profits by having more sales while passing on the savings to the consumer. The other day, I bought 2 boxes of cereals for the price of one.

But what happens if if I don’t want 2 boxes of cereal, I just want to buy one for the price of half? I mean it all boils down to buy at an individual level but still get the wholesale deals, correct?

Groupon use this strategy and steps up the game by getting a lot of people to buy together at this one vendor, so you can get the best price without requiring anyone to buy a lot. You only have to reach the “tipping point”, which the vendor specified, i.e the minimum amount of people for them to give out the good deal and make money at the same time. If the “tipping point” is not reached, you won’t get charged and vendor won’t sell it. Win win for everyone.

OMG, you say, why no one else ever did this before GroupOn? Well, there have been many, just in different ways. In fact, you probably already did this before.

1) In college, you and your roommates ever went to Costco or similar stores together and split the prices of items? It’s a group deal, you created it.

2) You ever had any junk mails coming to your home that goes something like buy over $50 and get 20% discount? and then you and your friends go buy together and receive a total 20% discount? Of course, as how you guys splitted the saving, is up 2 you. That’s a group deal.

3) You ever saw that PopEye family deals? Lots of chickens for cheaper? You and your friends got together and split the cost. Yum AND CHEAP.

4) You ever had a roommate in college renting condos together? You grouped together to get a two / three bedroom condo because it’s cheaper than each of you renting one condo. It’s a buy in group deal. You of course, at the time probably could not afford a one bedroom condo yourself, but you sure can get together with a friend and rent a 2 bedroom, cuz you don’t need 2 rooms. You just need one bedroom to sleep in. Well, the effect is a group deal. Ever thought of that? Okay, this one is a bit of a stretch.. (I just twisted your brain here intentionally, you probably felt something doesn’t seem right with the way I described, I’ll explain this later).

Still not as obvious to you? Well, there are all around you and yes, you can book them online or give them a call.

1) Travel industries have long offered group discounts
2) Tourist sites or Tour Guide companies prefer and sometimes only offer group rates.
3) AAA offers travel group because they have partnership with American Airlines’ travel agencies and they offer discounts for groups of 10 or more people going to the same place.
4) Ever heard of Timeshare? A group of people paying a low rate to live at hotels, different hotels all around the world!

Okay, so you are not a travel agency and it’s not for generic consumers. Besides, it’s related to travel. Okay. Fair enough. What about..

1) Concert halls or Sports Centers like Kenny Center in D.C. Most of these places offer group rates, you just have to look
2) Ticketmaster offer group rate for events.
3)… okay okay, stop

You are missing the point, you say. For general consumers, where are we going to get 10 to 20 peoples to buy together? We are not event coordinators. Even if we can get friends together, the hassle, jesus.. That’s why GroupOn is great! They bring in completely strangers together. You are correct, that’s the power of GroupOn and their advantages.

All good right? Consumer got it for cheap and merchants sold to more people. Well…..Ah…finally, after all that reading, we know you are going to say “well…”. You are correct. Let’s break down Groupon’s customers into two groups, the consumers, and the merchants.

Consumers

First, getting things at a cheaper price is always good as most of the people say, but are you really getting everything as good as if you were paying it at regular price? (Note, the points below are for consumers to consider, in no ways, am I bashing local businesses. There are consumers for local businesses, see my last paragraph in this “Consumer” section. )

The Whole Product

Buying merchandise and services is not only about price. It's what we call the "whole product". It involves in a few different areas such as quality, customer care, no hassle return policies and etc. As GroupOn consumer, you have to think the following

#1 Services

For services industry such as restaurants, doctor’s offices, fast food places, normally you will get a place you want, you will get the seats you want, you will get the food / services you want when you want it. You typically could not buy it online.

With GroupOn, you can easily purchase the offer online in the form of coupons, however you MIGHT find that the line is super busy because there are hundreds, if not thousands of people got the same deal, and it’s a Saturday! Well, you say, normally, you still get a busy restaurant, long waiting times (sometimes month) at a doctor’s offices and etc. But you know what the differences is? With the purchase you got at GroupOn, it’s POSSIBLE that it will be WORSE, but you already paid for it, it’s hard to back out! (Not that you can’t).

Please remember, you are buying from small businesses, that’s what GroupOn is focused on, can small businesses handle the traffic and handle the good services to you at the same time? When you bought at GroupOn, the tipping point might be 50 and there are only 50 people right now, but it’s possible to go very fast to 1000. What good does it do to book a wedding photographer for a whole day but there are 500 people before you? That’s almost 1.5 years later before he gets to you, your wedding I’m sure can not wait for it.

Without a coupon and a purchase before hand, well, you are more flexible. If the restaurant is busy, then you go elsewhere. If the doctor’s office is busy, then you will find another doctor. Ask yourself, if you know the line is busy and the appointment is long, very long. Will you get it? When was the last time you ordered a pizza and they tell you the wait time is 3 hours or longer, and you still went for it? Not likely or you simply eat really late :)

Consider, is it worth awhile to get discounts in exchange for bad services? Think carefully. I’ll give an example later.

#2 Products

For product industry such as clothing, jewelries, shoes, business cards and etc, are you really getting a good deal you have to ask yourself. Remember, these are Mom and Pop shops in your local area (in a few instances, they are chain stores), even with a discount, can they compete with super stores like Costco? Costco has a whole corporation behind it with billions as barging chips to buy in mass, such they can give sell you at a cheap price. Mom and Pop shop can’t. Can they compete with online stores like Amazon? Amazon has no middle man, no rents like Mom and Pop shops (0kay, they have warehouses and its operation costs, but seriously, they have good deals). You really have to research a bit instead of buying it just because its’ a deal with a big 50% discount slapped on it.

Here is a tip for those who wants to do the next hot online web 2.0 or web gazillion-point-o business. Do a group sales for Wholesalers. Meaning all vendors have to be wholesalers. You are acting as Costco and passing on the deals to consumers directly, no warehouses, no middle man. You will be the Costco / Wallmart killer! #2 point I just mentioned here will be moot.

Consider, are you sure this is the best price you can get?

#2 Quality and Quantity

Now a deal is only a deal if the quality is comparable at regular price or if it’s better than elsewhere. Getting a IPHONE for 50% off v.s at regular price is a deal! But the issue is, for one, you might never heard of this Mom and Pop shop before this deal, you won’t find out till you try it. If you like to try new things, then it’s cool. You probably already have the expectations that if it’s bad, then you won’t use it again. But if you are more conservative, you have to either do a bit of a research first on this Mom and Pop shop or you should had a previous PLEASEANT experience with them enough for you to go back.

Suppose you spent $100 on bad quality products or restaurants on 5 different deals. $20 each, great deal, however serves no purpose to you, you can barely eat the food, etc. Wouldn’t you regret that you did not spend the $100 on two of your favorite products/services at $50 each? Yes, it’s more expensive, but the experiences and quality they brought to you is worth every penny of it.

or
Look it another way, buying a product on a deal for $50, break in 2 weeks and you have to buy another good one for $100, is it really worth it v.s buying $100 in the beginning (twice the price) but it lasts much longer? I think you already know the answer to that.

Just remember this, don’t pay for crap even if they are cheap. I know I won’t.

Second assessment is quantity. It's somewhat related to #2 item above. Is it really cheap? Consider this. Will you need the item for a long period of time? I mean after all, a deal is only for that day, while it might sound cheap with a one time 50% discount for ONE item, do you really save compare to say..you buy a lot YOURSELF at a retail discount store? Quantity here makes a difference for you, not for the group.

Consider, are you willing to use discount in exchange for bad quality of products or services, or a "seems" cheap one day deal?

#4 Service Competitions

Not sure if you noticed this or not, Groupon is a Deal of the Day type of site. It’s not a price comparison site. The deal they bring to you might be a good deal for that shop compare to their regular price, but it might not be a good deal for your entire area / zip code. Shop around is always the key. It’s somewhat related to point #2, but that was focused on products, but this is talking about services. As services like restaurants can not be sold on Amazon.

Ask yourself, is it my first time buying from the store? If it is, then you really should be using a price comparison search engine for your local area or search multiple sites for comparisons. After all, other than price (which is of course important), you have no other data such as their customer services, quality and availability to asses against.

True stories, I’ve heard stories from my people who suffered from the above. One found out their appointment will be 6 month out after purchase (bad services), another one found out they could get online for a better deal without leaving the house (coned on price) , the last one, well, he found out the massage business is at a basement with dirty sheets! (bad quality) Needless to say, they weren’t happy campers. This one experiences and the money they spent, completely offsets their budget and either prevent them from getting similar things at a better place or paid a higher overall price for getting them at the end. My god, am I glad I didn’t get any of those “deals” with quotes.

With Groupon, you have to remember its sources are s small businesses, not big stores like Amazon, or BestBuy or Wallmart. They might be honest businesses truly with good products/services at very good prices, but if they are overwhelmed by the traffic, the victim is you! The consumer.

In addition, remember the #4 example I gave earlier about 2 friends together to share a 2 bedroom condo as oppose to each get a 1 bedroom condo? I said it was a deal. Well, i was twisting it. First, depends on how you look at it, you might got a deal if you don’t care about privacy. In another words, you suffered on the quality of living. If you care about privacy, then it’s not a deal no matter how you dice it. To the merchant however, they essentially lost some because instead of having 2 people each rent a 1 bedroom condo, now you both lived in a 2 bedroom! In this case, the merchant IS their own supplier. Every penny they lost, it’s lost.

This will only be a deal IF

1) You get a one bedroom condo for half of the regular 1 bedroom price or you pay 1/4 of the price to share the 2-bedroom with your friend. We all know that’s not going to happen as your Condo Company will loose a lot money and your roommate definitely won’t pay for 3/4 of the price (well, there are exceptions to this rule. If you are that guy/gal pays for the 1/4, consider yourself lucky and be forever grateful to your friend)

2) You rent the 1 bedroom condo with a discount IF YOU sign a yearly contract v.s monthly contract or multiple years contract v.s a single year contract.

You see, in the above case, “Buy More & Save More” DOES NOT apply to “The more people buy, the more you save”. Two people living in the 2 bedroom condo will cost exactly the same as 1 person living at the 2 bedroom condo

Two types of “Buy More & Save More”

Going back to the original phrase "Buy More & Save More". Consumers, you first have to ask yourself, what does it mean to you? Your probably will say, buy in bulk right? Okay, if so, then answer this question. What's the point of you buy in Costco v.s you buy at GroupOn? Why do you buy at Costco? I mean after all, they are all trying to "Save more for you" correct?

Think long and hard.....

...

Okay. Let me break it to you. Here are the difference, long term savings v.s short term savings.

Long Term

#1) The more you buy (money or quantity), the more you save in the long term. Costco/Wallmart, sell you in bulk is because they know you need it, while it won't save you any money in the short term, as you buy more than you currently need it, so you actually spend a bit more than you should right now, but you will save in the long term. However, you will keep going back to them realizing the long term benefits and Costco / Wallmart in return retain you as a loyal customer. That now my friend is a Win/Win.

It's important to note though. As I've previously described, its' not just about the price only, it's about the "whole product". This does not necessarily requires the merchant to have the ability to acquire cheap prices by buying huge quantity nor require a huge quantity of consumers to stay profitable. You as consumer does not save much in the short term as well necessarily. However, in the long run, you save quite a bit and the merchant at the same time, continue to make profits by having you as their long term customer. The key is? Your quality might be better or the quantity you need in the long term will increase.

Short Term

#1) More people buy, more saving. As previously described, this is really about a one time saving in the short term. While 50% discount saving on one item is great (YIPPIE), buying another one at full price, suddenly doesn't sound so appealing let along if you want to buy a lot and keep buying. The key is each consumer will get a discounted at a great price without buying a whole lot, for a selected period of time, for one time only.

As I explained earlier, save $20 for $50 on one transaction, with a total of 10 transactions will cost you, 1*$20(one time only)+ 9*($50)=$470.
Another vendor without discount, cost you $35. That's 75% more expensive than $20. However, in the long run it costs 10*$35 = $350.

In addition, if you will use that service or products a lot in the future, merchants sometimes have customer retention / appreciation plans such as (exactly how it is done depends on the merchant. Either one time saving or overtime, like the 10th time you come, you get it for free type of deals)

But of course, we all understand, a “deal” is a marketing gimmick, consumer will forget everything and just go for it. However, my point is GroupOn focuses on small businesses and not many small businesses by nature can give really cheap prices using the “Buy More, Save More” "Long Term" at a 50% discount rate they are taunting around. If they try to be, then they are doing it all wrong for all the wrong reasons!! The goal to use GroupOn is to get new customers in the door while you have plans to convert them to a happy long customers.

Think about it for a second here. How is the overall consumer experience in the long term will be? Can the merchant sustain the profitability without incur on heavy physical burden? For instance, (and this is conservative), used to have $2 profit per customer, now it’s $1 profit per customers. This means, they have to handle twice as many people to reach the same profit!! Or they must have a really big margin which seriously puts the business in jeopardy in the long term (maybe high rent?).

Consumers should NOT buy multiple deals just because they are cheap. Merchants should not use Gourpon blindly believing "Buy more & Make More". More people does not = More Money. It's a lose /lose deal. Only by having policies in places for re-warding existing customers, would you convert new customers to long term customers and long term customers will realize in the long run, it saves them more even through a daily price might be a bit more expensive, why? because they trust you and your "product"! Not having to risk getting craps multiple times. (Let's see, customer reward card, a new coupon after every other purchase, customer appreciation day, coupons for existing customers reguarly, etc etc)

Such, I do think Groupon has the responsibility to not mislead the consumer into thinking, the cheaper it is and the more people join on the deal, the better the deal is. The whole idea of “Groupon uses collective buying power to offer unbeatable prices and provide a win-win for businesses and consumers” is somewhat sickening to me. Believe me, not a lot buyers think about the stuff till after they purchased it and get pissed about one of items between #1 to #4.

Groupon instead is an Advertising / Coupon company and merchants' common sense in regards to effect of coupon should kick in. But at least it's much better than leading merchants to think, this hot web2.0 online business will make you merchants rich! Ride on the wave people. Everyone is doing it! Just look at the number.

Which leads to as the title suggested, by giving consumers / merchant such an experiences, is it a good business for the long term?

Some of you might say, it’s a stupid question. Can you see GroupOn is making millions and millions? Well, yes. In fact, did you know Ponzi Schemes gets “billions” of "ROI" over the decades? But in reality, everyone lost, except the guy who organized the Ponzi – Ponzi, who collected commission every time. I’m not sayinig GroupOn is a Ponzi scheme at all (it's just the structuring/marekting of having both of their customers join for the wrong reason is misleading), as a a consumer you just have to know when a deal is the right deal for you. However by saying how much a business makes at the time, makes no senses at all especially there are valid concerns over the long term stability of its bases and because there are plenty of more people waiting in lineto feed it, this model won't easily be discovered till its base (the merchants) start to pull out in mass due to whatever reasons as investors pull out of Ponzi during economy down time, suddenly, it collapsed.

SO, having said all that, bottom line, if

1) It's a one time deal for you, get it cheap even though you don't need it and no plan to go back anyway. Use GroupOn. You can find some stuffs.

2) You truly found a business locally, promoting a RARE deal that is cheap, the product/services is good, fully equipped with handling everything for you, go for it.

3) Their deal doesn’t get thousands of customers, but only a few of you, price decent. Go for it.

But if you find the item is already on sale at a store you frequently visits, then you really have to ask yourself, is that relly a deal? Do my trusted store have special events that will sell it for as cheap? Are they as trust worthy? Is it as easy to get as my regular store? Will I waste my money on this deal? Do they have too many restrictions? If any one of these rings a bell, you might reconsider to get a "deal".

Okay. Take a break. Be back later for the other side of the analysis. The merchants.

ASP.NET 2.0 Forms Authentication and Active Directory Installation

Liming — Wed, 19 Mar 2008 18:16:00 GMT

Earlier this week, I've posted an article on this subject and it can be found on the Jumptree Blog.

Overall, I went through the steps from setting up up Active directory to how ASP.NET authenticates against the new setup. I always find it is more clear to developers if we know how the system works behind the scene.

As we all know, larger size corporations and agencies normally uses Active Directory to manage their internal users for various of reasons. Personally, because we are a small shop and the contracts we've dealt with were mostly in hosting environments, such we never had the need to look into supporting Active Directory. However, this has changed ever since Jumptree were being tested in such environments. We realized by providing the support for such authentication is essential to expanding our customer basis.

I mentioned at the end of the article, there are still much to be done. The reason is it's very often to have multiple Active Directories within an organization and users are spread through out the multiples domains. We need to research further on how to authenticate the proper domain based on user's selection in addition to build the proper admin module for multiple domain registrations.

In addition, we find that a lot of organizations also use "SiteMinder" from Computer Associates for authentication. This makes it very interesting and it appears at least to us that only very huge organizations use "SiteMinder" and yet, the resources on ASP.NET 2.0 / SiteMinder integration is rare to find. We are doing research on this subject as well and when I do find out how to do this, I will write another article following up on this subject. If any of you know anything on this subject or would like to learn about it, definitely let me know.

Anyway, hope the article helps some of the .NET developers out there on with Active directory / Forms Authentication development issues.

Jumptree V1.1 is released today on 1/1/2008

Liming — Tue, 01 Jan 2008 12:19:00 GMT

Dear Jumptree users:

Maybe we are just a tiny bit superstitious :), but it just seemed like the best day to release v1.1 is on 1/1 :) , so thanks again for your understanding and today, we are proud to present you with the immediate availability of Jumptree V1.1 for download.

As we have announced before, v1.1 is a free upgrade to all v1.0 purchased users, such, please log into our customer portal and you will find the v1.1 release file there for download.

Other than the v1.1 features and the screen-shots that I've already showed in the previous post, I want to point that the installer has been upgraded to ease your migration from v1.0 to v1.1 as well. Simply choose "Upgrade from v1.0 to v1.1" and you will be good to go. Here is a screen shot of the new installer.

Of course, the first thing you have to is to delete the old v1.0 files and replace them with the new v1.1 files. Here is what you need to do in 4 simple steps.

1. Delete All existing v1.0 files Except

Directory : /App_Data/
Files : PMAppSetting.config, PMDBConnection.config, PMEmailSMTP.config

2. Copy all v1.1 files over except the above mentioned config files and the App_Data folder
3. Copy v1.1 /App_Data/SqlScripts/ folder to your exisiting /App_Data/ directory
4. Lastly, launch your installer at http://[your url]/setup/default.aspx

Feature wise, to further improve your experience, our designer Jackson Lin has added special CSS for printing purposes and here is a snap shot of the task detail in "Print Preview".

Now, you have no excuses to not bring them along to your weekly meetings :)

In addition, Jumptree now supports the inputs and displays of all languages. Here is a screen shot of the word "Hello!" in 9 different languages.

In the previous edition, some of our Non-English customers (mainly French users and Chinese users) pointed out that their native characters became garbage questions marks and it was a great concern to them. Such it is our pleasure to finally provide the support for it.

Some of the Chinese readers might have already noticed that the names are displayed in both Traditional and Simplified Chinese, so yes, because it's UTF-8 encoded, both characters can co-exists without any special treatment.

Another screen shot with all Chinese characters

In v1.0, some project managers complained that by viewing project details, there were many tasks missing due to the fact that there were tasks not attached to milestones and such were missing in project detail, we're glad to have fixed this issue and present you with a complete one-page view of your project in its entirety. (Notice, now we displays "tasks with no milestones" in a grid of its own)

Okay, these are just some of the highlights in V1.1 in addition to the ones that I've described in the previous post. There are many other small usability improvements throughout the software in this version and we are sure when you get it, you'll quickly find out.

Thank you

InfoWorld - Java is becoming the new Cobol.

Liming — Fri, 28 Dec 2007 20:51:00 GMT

This article pretty summarizes the sentiments of developers who worked extensively on both the Java environment and the .Net environments.

Again, I can’t comment on Ruby on Rail or PHP because I don’t have experiences with them, but what I CAN tell people is that if you are a Java/Ruby/PHP developer then you have to try out the .NET platform yourself to truly appreciate what you are missing.

It’s not a conflicted statement. I haven’t tasted apple before, but I can still tell you if you’ve never tried orange, then you’ve missed something.

I can’t argue with those who haven’t truly used .Net, because as with any new languages and frameworks, there is a bit of learning curve in the beginning. Frustrations and mis-understandings of the “right way” to do something new, a lot of times, prevent people from “crossing” the chasm.

Case in point, I get this type of complaints a lot. For example, ASP.NET “ViewState” is huge and simply a waste of bandwidth, it unnecessarily produces huge page size. The keyword is “unnecessarily” as I tell my friends. If it’s unnecessary, then please turn off the view state. Use ViewState only if you need it, please don’t abuse it. A typical case of the paradox of choices which I admit, Microsoft offers way too many goodies to developers these days, spoiled us way too much. It definitely encouraged some bad practices simply because they are there.

It’s a leap in faith for those non .Net developers, no questions about it, however with a little bit of patience and investment in the beginning, what you’ll find out is that the return of investments of .NET platform far exceeds your expectations. The time invested into the same application, the time you saved with your family, meeting clients’ expectations and timeline, the headaches you’ve saved just to get your environment right and at finally, as a company decision maker, the ease of finding another equally qualified .NET developer without a steep learning curve; a typical short-coming suffers from the J2EE side.

For example, a Senior J2EE developer with JSP, Servlet and EJBs using IBM Websphere 5.1 on the windows platform, won’t matter much if the new environment is JSF/Spring/Hibernate using JBoss 5.0 on the Sun Solaris Unix platform. I personally know many of my Java colleague runs away from such cases even though they are one of the best senior J2EE developers you can find in their specialized combo skill sets. It’s truly unfortunate.

Java won’t be phased out, Java won’t die, but Java sure will taste the fury of the products developed by the .Net developers in the next few years especially with what .NET 3.5 has to offer these days. You can sigh, you can wish, but the fact remains, develop AND providing support on the .NET platform simply saves more time and human resources than on the Java platform.

This ends my thoughts as the *Java Sellout* for today , happy new year everyone!
