With over 60 Internet regulations, the Chinese government has successfully built a virtual Great Wall that even Google got tired of climbing over. On March 22, 2010, Google officially redirected all traffic from its Chinese mainland site to its uncensored Hong Kong site. Eight days later, all hits for Google and its other international sites ended in a DNS error for mainland Chinese netizens. Some fear the ban may be permanent.
In these days there are many projects whose aim is to bring new languages to the browser by compiling them to JavaScript. Among the others one can mention ClojureScript, CoffeScript, Dart, haXe, Emscripten, Amber Smalltalk.
I'd like to try a few of these out, but I am not sure what I should be looking for when evaluating these languages to see if they are suitable for production.
How should I evaluate a new browser language, and what are the pitfalls I should be looking for?
I like the following quote which I found on codinghorror:[As Steve points out this is one key difference between junior and senior developers:]
In the old days, seeing too much code at once quite
frankly exceeded my complexity threshold, and when I had to work with
it I'd typically try to rewrite it or at least comment it heavily.
Today, however, I just slog through it without
complaining (much). When I have a specific goal in mind and a
complicated piece of code to write, I spend my time making it happen
rather than telling myself stories about it [in comments].
I am a college foundation student and I am really having trouble on which major I should choose between a B.Sc in computer science or software engineering.I have always wanted to be a lead software developer at a big company and I am really interested in coding starting my own website and even create my own apps and software.I really don't have a strong background in programming.And here i am looking at this piece of paper asking me to choose from the two and i don't want to make a mistake that maybe will make me regret.So guys please help me.S.0.S
I'm a newbie to Ubuntu and Im looking to run Java code from the command line. Ive checked that path as well. The interesting thing is the code compiles but fails to run
ie.
user@ubuntu:~/py-scripts$ javac Main.java' works well.
but when I do .
`user@ubuntu:~/py-scripts$ java Main
I get the following error

Almost everyone is building a website these days, but by saying that one is building the website from scratch, he implies that his knowledge on the matter is almost non-existent. In this case, seeking for answers online can overwhelm him with information. Therefore, instead of trying to learn all the processes involved in building the website by reading about it, a better option would be to go ahead at building one and learn the ropes hands on.
If you’re going to TechEd North America this year, Sams Publishing will be giving away 9 advanced reader copies. In order to win a copy, be sure to follow the InformIT Twitter account and the #TechEd hash tag. Sporadically throughout the day a tweet will be sent out stating that the first person who comes to the booth and mentions my book will get a copy. The give away will probably occur over multiple days, so be sure to keep an eye on Twitter. Technorati Tags: Books,Sams Teach Yourself C# 2010
In my previous job, we had several cases where schema changes or incorrect developer assumptions in the middle tier or application logic would lead to type mismatches. We would have a stored procedure that returns a BIT column, but then change the procedure to have something like CASE WHEN <condition> THEN 1 ELSE 0 END. In this case SQL Server would return an INT as a catch-all, and if .NET was expecting a boolean, BOOM. Wouldn't it be nice if the application could check the result set of the...(read more)
I have begun a career as a web application and database developer while slowly discovering the passion I have for work in the international development sector. Since this is not the most obvious line of work for someone with my credentials, it seems to me that special care must be taken in order to court international non-governmental organisations (NGOs) and position myself in the field.
Aside from adding grant-writing to my skill set and getting volunteer experience, what indispensable advice do you have for a fledgling programmer who wants to save the world?

This blog entry is intended to provide a narrow and brief look into a way to use the Select extension method that I had until recently overlooked. Every developer who is using IEnumerable extension methods to work with data has been exposed to the Select extension method, because it is a pretty critical piece of almost every query over a collection of objects. The method is defined on type IEnumerable and takes as its argument a function that accepts an item from the collection and returns an object which will be an item within the returned collection. This allows you to perform transformations on the source collection. A somewhat contrived example would be the following code that transforms a collection of strings into a collection of anonymous objects: 1: var media = new[] {"book", "cd", "tape"};
2: var transformed = media.Select( item =>
3: {
4: Media = item
5: } );
This code transforms the array of strings into a collection of objects which each have a string property called Media.
If every developer using the LINQ extension methods already knows this, why am I blogging about it? I’m blogging about it because the method has another overload that I hadn’t seen before I needed it a few weeks back and I thought I would share a little about it with whoever happens upon my blog. In the other overload, the function defined in the first overload as:
1: Func<TSource, TResult>
is instead defined as:
1: Func<TSource, int, TResult>
The additional parameter is an integer representing the current element’s position in the enumerable sequence. I used this information in what I thought was a pretty cool way to compare collections and I’ll probably blog about that sometime in the near future, but for now we’ll continue with the contrived example I’ve already started to keep things simple and show how this works. The following code sample shows how the positional information could be used in an alternating color scenario. I’m using a foreach loop because IEnumerable doesn’t have a ForEach extension, but many libraries do add the ForEach extension to IEnumerable so you can update the code if you’re using one of these libraries or have created your own.
1: var media = new[] {"book", "cd", "tape"};
2: foreach (var result in media.Select(
3: (item, index) =>
4: new { Item = item, Index = index }))
5: {
6: Console.ForegroundColor = result.Index % 2 == 0
7: ? ConsoleColor.Blue : ConsoleColor.Yellow;
8: Console.WriteLine(result.Item);
9: }

I saw in Disk Usage Analyzer I have 3.13.0-xx for 8 minor versions of the kernel in /lib/modules. Each is around 200MB.
I remember having to go through in Synaptic and remove those old Linux versions before, but hasn't this bug been fixed? Is it just paranoid default setting, that perhaps all of the last half dozen kernels might become unbootable, so it keeps each old one around? Or do I have some developer setting enabled by accident that causes this?

There was a time when we had to worry about manually updating desktop applications. Adobe Flash and Reader were full of security holes and didn’t update themselves, for example — but those days are largely behind us. The Windows desktop is the only big software platform that doesn’t automatically update applications, forcing every developer to code their own updater. This isn’t ideal, but developers have now largely stepped up to the plate.
I realized I have a difficulty creating OOP designs. I spent many time deciding if this property is correctly set it to X class.
For example, this is a post which has a few days: http://codereview.stackexchange.com/questions/8041/how-to-improve-my-factory-design
I'm not convinced of my code. So I want to improve my designs, take less time creating it.
How did you learn creating good designs? Some books that you can recommend me?
OEL 5.5 got pushed to ULN last night.
we are creating the 5.5 base channel right now - for those that want the convenience of register to a specific update channel only. This is something we have done since the beginning (on ULN). The ISO images will appear on e-delivery in a number of daysand for those customers that need urgent ISO access they can file a support SR.

Do you test your SQL or SQL generated by your database framework?
There are frameworks like DbUnit that allow you to create real in-memory database and execute real SQL. But its very hard to use(not developer-friendly so to speak), because you need to first prepare test data(and it should not be shared between tests).
P.S. I don't mean mocking database or framework's database methods, but tests that make you 99% sure that your SQL is working even after some hardcore refactoring.

Trying to install 11.04 daily for the last couple days but, no matter what I try (wifi connected, wifi not connected, disk blank, disk prepartitioned...), if just "hangs" at the first window (pick your language) with a non-stop hourglass after hitting next. I ran into a different issue when trying to use the alternate installer image. This is on a Stinkpad T42. Should ubiquity at least tell me whats going on?!? I tried to find a log but /var/log/installer* isn't present.
