• Versioning system for MS Access

  - by Melissa L

  I am currently the only developer on a MS Access project, but we may soon be adding developers onto to the project. This will be my first time sharing the load on a single MS Access project and I'm a bit clueless as to what versioning system (ex. SubVersion) might work best. Any suggestions on programs I should be taking a look at or staying away from? Thanks for your help!

• Where to wire up events?

  - by Jeffrey Cameron

  I'm using Ninject (1.5 ... soon to be 2) and I'm curious how other people use Ninject or other IoC containers to help wire up events to objects? It seems to me in my code that I'm doing it herky-jerky all over the place and would love some advice on how to clean it up a bit.

• Is there a full REPL for Erlang?

  - by Gabriel Cuvillier

  Is there a way to have a full interpreter in Erlang, not just a "shell". Since it is a dynamic language, not being able to define named functions in the interpreter is a little bit disappointing... I suspect that it is because compilation units (modules) must be explicitly compiled for their execution by the VM, but maybe a REPL acting as a dynamic/recompilable module exist?

• Serialize checkbox array, also get checkboxes with off-value

  - by guzh

  Hi, I was wondering if this is possible. The serialize-string will be inserted in a mySQL-database, so it would be fine if all checkboxes would be inserted and not only the ones that is ticked(on). it's possible to make on column in the database for each of the checkboxes, and use this if/else-statement: if(isset($_GET['checkbox'])) { // It's checked! } else { // not checked! } but its a bit unappropriate...

• Event for finger being moved off button but not lifted in objective C (iphone)

  - by Jonathan

  Is there an event which will get whether the user has moved his finger outside of the button? Kind of like TouchUpOutside except without the "up" bit. Like how the iphone keyboard, the letter gets smaller (back to normal) as you move your finger of the letter.

• Can I move beaker.SessionMiddleware to handle method somehow?

  - by Alexander A.Sosnovskiy

  It's a bit ugly that many lines of code fall into "__main__". Can someone give me a tip of how to move SessionMiddleware into handle method? I should notice that I use session in CoreXmlParser. Thanks in advance ! def handle(environ, start_response): req = webob.Request(environ) c = CoreXmlParser(req) resp = webob.Response(body=c(), charset = 'utf-8', status='200 OK', \ request=req, content_type='text/xml') resp(environ, start_response) return resp.app_iter if __name__ == '__main__': #parse config file for session options app = SessionMiddleware(handle, some_session_opts_here) from flup.server.fcgi import WSGIServer WSGIServer(app).run()

  Is there a way to install Internet Explorer 6 in Windows 7? I need to test the layout of a website. Using a website which takes screenshots is a bit awkward, as often you are making changes and testing the effect. Thanks

• How can I emulate the ASP.NET Ajax UpdatePanel when using ASP.NET MVC?

  - by Gary McGill

  In "traditional" ASP.NET (Web Forms), the UpdatePanel control lets you do a partial refresh of a part of a page. You don't need to write much code to hook this up. What's the equivalent in ASP.NET MVC? I'm guessing I'd need to use a partial view for the bit that I want to update, then on the client side retrieve that HTML and pump it into the innerHtml of the correct DIV? A tutorial/example would be helpful...

• TCP sequence number question

  - by Meta

  This is more of a theoretical question than an actual problem I have. If I understand correctly, the sequence number in the TCP header of a packet is the index of the first byte in the packet in the whole stream, correct? If that is the case, since the sequence number is an unsigned 32-bit integer, then what happens after more than FFFFFFFF = 4294967295 bytes are transferred? Will the sequence number wrap around, or will the sender send a SYN packet to restart at 0?

• What is so bad about Singletons

  - by Ewan Makepeace

  The Singleton pattern is a fully paid up member of the GoF Patterns Book but lately seems rather orphaned by the developer world. I still use quite a lot of singletons, especially for Factory classes, and while you have to be a bit careful about multithreading issues (like any class actually) fail to see why they are so awful. This site especially seems to assume that everyone agrees that Singletons are evil. Why?

• For distributed applications, which to use, ASIO vs. MPI?

  - by Rhubarb

  I am a bit confused about this. If you're building a distributed application, which in some cases may perform parallel operations (although not necessarily mathematical), should you use ASIO or something like MPI? I take it MPI is a higher level than ASIO, but it's not clear where in the stack one would begin.

  A z buffer is just a 3d array that shows what object should be written in front of another object. each element in the array represents a pixel that holds a value from 0.0 to 1.0. My question is if that is all a z buffer does, then why are some buffers 24bit, 32bit, and 16 bit ??

• How do you draw a string centered vertically in Java?

  - by Paul Alexander

  I know it's a simple concept but I'm struggling with the font metrics. Centering horizontally isn't too hard but vertically seems a bit difficult. I've tried using the FontMetrics getAscent, getLeading, getXXXX methods in various combinations but no matter what I've tried the text is always off by a few pixels. Is there a way to measure the exact height of the text so that it is exactly centered.

• How to build and deploy Python web applications

  - by sverrejoh

  I have a Python web application consisting of several Python packages. What is the best way of building and deploying this to the servers? Currently I'm deploying the packages with Capistrano, installing the packages into a virtualenv with bash, and configuring the servers with puppet, but I would like to go for a more Python based solution. I've been looking a bit into zc.buildout, but it's not clear for me what I can/should use it for.
