• What is a de-compiler how does it work?

  - by thyrgle

  So is a decompiler really a thing that gives gives the source of a compiled/interpreted piece of code? Because to me that sounds impossible. How would you get the names of the functions, variables, classes, etc if it is compiled. Or am I misinterpreting the definition? How does it work? And what is the general principal behind making one?

• Unit Testing - not testable code converted to testable code

  - by imak

  I have read so many places is that if your code is not test-able that mean code is not well written. So that makes me start writing a code that is test-able and to start using some unit testing framework. With this though I start looking for some example with piece of code that is not testable and gradually converted to a testable code. I find tons of examples on unit testing but if someone can provide an example like above it probably can jump start things for me. TIA

• Django: How to handle imports in a reusable app

  - by facha

  everyone I'm just starting with django. It is not quite clear to me, how should I write an app I could reuse later. In every tutorial I read I see the same piece of code: view.py from project.app.models import MyModel So, if I move my apps to another project, I'll have to modify the "project.app.models" so that it looks like "project2.app.models" for every app I move. Is there a way to avoid that? Thanks in advance.

• Anything like VisualSVN Server for Mercurial?

  - by Billy ONeal

  VisualSVN server is a nice piece of software; particularly in that it uses the builtin Windows authentication mechanism on my server. I'd like to try to start using Mercurial though, and I'd like to keep the Windows authentication scheme. Is there some way to set this kind of thing up using the tools available on Windows Server 2008 R2 Standard (in particular, IIS 7)?

  Would it be possible to run ssh-keygen without human interaction? I have a shell script that takes care of server deployment from start to finish, but ssh-keygen is the only remaining piece that still requires my input. Would it be possible to feed the parameters to it? Or is there something similar to debconf-set-selections that could be used for this? *running Debian

• Python: Split, strip, and join in one line

  - by PandemoniumSyndicate

  I'm curious if their is some python magic I may not know to accomplish a bit of frivolity given the line: csvData.append(','.join([line.split(":").strip() for x in L])) I'm attempting to split a line on :, trim whitespace around it, and join on , problem is, since the array is returned from line.split(":"), the for x in L #<== L doesn't exist! causes issues since I have no name for the array returned by line.split(":") So I'm curious if there is a sexy piece of syntax I could use to accomplish this in one shot? Cheers!

• Monochrome BitMap Library

  - by Asad Jibran Ahmed

  I am trying to create a piece of software that can be used to create VERY large (10000x10000) sized bitmaps. All I need is something that can work in monochrome, since the required output is a matrix containing details of black and white pixels in the bitmap. The closest thing I can think of is a font editor, but the size is a problem. Is there any library out there that I can use to create the software, or will I have to write the whole thing from the start?

• Dynamic memory managment under Linux

  - by petersohn

  I know that under Windows, there are API functions like global_alloc() and such, which allocate memory, and return a handle, then this handle can be locked and a pointer returned, then unlocked again. When unlocked, the system can move this piece of memory around when it runs low on space, optimising memory usage. My question is that is there something similar under Linux, and if not, how does Linux optimize its memory usage?

• ServerVariables and POST Data

  - by tyndall

  I've got a piece of tracking code which is capturing REMOTE_HOST, SERVER, REQUEST_METHOD, SCRIPT_NAME and QUERY_STRING. It grabs these from ServerVariables and sticks them in a database by user and IP. What is the best way to pick up the exact contents of what was posted back to a URL in ASP.NET? Is there an HTTP_POST? I'd rather not grab something and then have to parse it.

• Is web-browser to Excel interprocess communication possible

  - by Abiel

  Is is possible to write a browser plugin (one that requires the user to install something is OK) that would allow interprocess communication between the browser and a running instance of Excel (on Windows)? For example, suppose I want the user to be able to click something within their browser, and then have a piece of text drop into the selected cell in Excel as a result. This is certainly possible to do with a regular desktop application and Excel, but I'm not sure if it is possible with a browser, for security reasons.
