• Good example of Reactive Extensions Use

  - by Keith Hill

  I understand the basics of Rx. Where I'm struggling is how you would actually use this beyond academic examples? What are some common, simple real-world scenarios where Rx is a much better solution than what we have today in .NET?

• Objective-C Array/List Question

  - by Dave C

  What is the best practice, even in general programming, when you have an undefined, possibly infinite, amount of items that you need in an array but don't have defined bounds. Can you define an endless array in objective c that you can keep pushing items onto, like other lanaguages have a list item. Thanks for any help.

• Why there is no open source framework (like Java) for C# application development?

  - by Calvin

  Hi, C# is much more popular than Java in recent years. As a general-purpose programming language, many people feel that C# is better designed than Java. Why until now there is no open source framework for C# application development? Why no one take the initiative to develop a open source framework for C# which is comparable to Java? (Many people say Mono is not a mature framework and should not be used in serious application development.) Calvin

• Dynamic UI vs Static UI

  - by Damien

  I've been wondering, at what point should I give up the convenience of a static data entry form with designer support for a dynamic UI which removes a lot of code duplication? There seems to be a conflict in the programming world where people constantly try to remove code repetition to improve maintainability and yet when it comes to forms, that all goes out of the window and everything gets added explicitly to the forms. What signs should I look for to know when it's time to leave the designer in the dust and create a dynamic UI?

• Rich Text Editor with Tab and Table Support

  - by Chris W.

  We are developing a project for a client that requires a rich text editor that supports both tables and "real" tabs for indentation. Of the editors we've looked at, both TinyMCE and FreeRichTextEditor are very close fits, but indenting with tab seems to only work in WebKit-based browsers. Is there a (preferably free) cross-browser compatible rich text editor that supports both of these features, or a way of 'fixing' tab support in Trident and Mozilla-based browsers?

• How can I tell if a set of parens in perl code will act as grouping parens or form a list?

  - by Ryan Thompson

  In perl, parentheses are used for overriding precedence (as in most programming languages) as well as for creating lists. How can I tell if a particular pair of parens will be treated as a grouping construct or a one-element list? For example, I'm pretty sure this is a scalar and not a one-element list: (1 + 1) But what about more complex expressions? Is there an easy way to tell?

• Why are there so many Database Management Systems?

  - by mr.bio

  Why are there so many Database management systems? I am not an DB expert and I've never thought about using another Database other than mySQL. Programming languages offer different paradigms, so it makes sense to choose a specific language for your purpose. Question What are the factors in choosing a specific Database management system ?

• Deploy application to iPhone Simulator

  - by Craig Warren

  Hi, I am looking for a way to deploy my application to another users simulator. To be blunt the person needs to show the application on the simulator and is not capable of compiling the source code and I don't have the time to produce the instructions. What I want to do is provide them with the .app (or another) file and have them install it in the simulator just like they can do with any real iPhone Device. Does anyone know how I can do this?

• Is LuaJIT really faster than every other JIT-ed dynamic languages?

  - by Gabriel Cuvillier

  According to the computer language benchmark game, the LuaJIT implementation seems to beat every other JIT-ed dynamic language (V8, Tracemonkey, PLT Scheme, Erlang HIPE) by an order of magnitude. I know that these benchmarks are not representative (as they say: "Which programming language implementations have the fastest benchmark programs?"), but this is still really impressive. In practice, is it really the case? Someone have tested that Lua implementation?

• NTFS drivers on Linux

  - by Jack

  Hopefully this is programming related. Many people have reported that the NTFS-3G driver works perfectly for writing to NTFS drives without any problems. If NTFS has been successfully reverse engineered to a useful degree, then why is the kernel driver still only read-only, with write support being very dangerous.....just as it was 5 years agi?

• Program compiled with MSVC 9 won't start on a vanilla SP3 XP

  - by jemper

  I installed XP on a virtual machine, updated it to SP3 and then tested a small program compiled with Visual C++ 2008 on my real computer - however it didn't start but outputted only an error saying that a problem had been detected and that a reinstall of the application (mine is 10KB in size and doesn't even have an installation) could fix the problem. What is required to run programs compiled with MSVC 9? Can I just include some dlls for it to work everywhere?

• Why do transfer objects need to implement Serializable?

  - by smaye81

  I realized today that I have blindly just followed this requirement for years without ever really asking why. Today, I ran across a NotSerializableException with a model object I created from scratch and I realized enough is enough. I was told this was because of session replication between load-balanced servers, but I know I've seen other objects at session scope that do not implement Serializable. Is this the real reason?
