• Advice on translating code from very unrelated languages (in this case Scheme to Python)?

  - by Michael

  Reasoning: I'm trying to convert a large library from Scheme to Python Are there any good strategies for doing this kind of conversion? Specifically cross-paradigm in this case since Python is more OO and Scheme is Functional. Totally subjective so I'm making it community wiki

• Transitioning from the web to the desktop

  - by Paul Anderssen

  Can anyone recommend a language, library, framework or book which focuses on GUI programming from the perspective of a web developer? I have experience in web development, for example HTML/AJAX/PHP/MySQL among similar technologies. However, I have never programmed my own back-end, or any kind of standalone program. Does anyone have experience making this transition, and what would I best study to help make the leap from the browser to creating programs with GUIs (primarily for Windows)?

• Mac OS X & MAMP - How to run mysql without having to type in the full path?

  - by BigDogsBarking

  Right now, if I want to run mysql, I have to do /Applications/MAMP/Library/bin/mysql -u user -ppass... I'd be a happy camper if I could just do mysql -u user -ppass.... Been googling around, but haven't been able to find anything... Have a feeling I'm using dumb search terms, so if anyone here knows how to do this, that'd be awesome...

• Tool for converting subset of PHP code into Java/Scala/Groovy?

  - by Alex R

  Do any exist? Ideally it would also come with a library of basic PHP functions. I have a bunch of simple PHP scripts (no extensions, no fancy dynamic hacks, etc) I'd like to convert to Java... It would be great if a tool could do 80% of the work while I do the other 20%.

• Python: Container object that preserves ordering and enforces uniqueness?

  - by Infinity

  Is there anything like this in the standard library? I've looked but haven't found it. It needs to be like a list (preserves order) but also like a set (elements can only appear once). So if you give it ['a', 'b', 'a'] it should return ['a', 'b'] Thanks!

• Are there any good free .Net network libraries? (FTP, SFTP, SSH, etc.)

  - by Kilhoffer

  I'm a bit surprised I haven't found a good open source library for performing common network tasks. There are a few very good commercial libraries, but they're too expensive to use on an open source project. Anyone know of any?

• why my C++ output executable is so big?

  - by Vincenzo

  I have a rather simple C++ project, which uses boost::regex library. The output I'm getting is 3.5Mb in size. As I understand I'm statically linking all boost .CPP files, including all functions/methods. Maybe it's possible somehow to instruct my linker to use only necessary elements from boost, not all of them? Thanks.

  - by Nishan

  I am trying to parse a string which in JSON format only that keys are not enclosed in quotes. I can very well parse this string in Javascript, but can not find a Java API which will help me parse this. All the APIs I tried assumes strict JSON format. Can anyone suggest a library which has an option to parse this, or a whole new approach to the problem (say like use regex instead) ?

Trouble is I'm a Javascript noob :-(, so if you figure this out please share as much of your code as possible. Thanks much!

  Hi Using Actionscript and or in the Flash IDE you can either instantiate bitmaps from the library, or simply import bitmaps into the timeline of a MovieClip to create an image sequence. How would you do the same thing in InterfaceBuilder and-or using ObjectiveC? Do I need to create a new view for each and every image?

• How to resize an image smoothly (with resampling) using Windows API calls?

  - by Clay Nichols

  I need to resize images and resample them so they don't end up all jagged (I think that's called aliasing). I found some code (sorry, lost the link) that does this in pure VB6 code but it's a bit slow (2-5 seconds) and I'm displaying pictures in real time so I need something faster. I seem to recall seeing some examples of doing this with the GDI+ library. An example in VB6 would be ideal, but I can probably work with a simple example with Windows API calls in another language.

• Do you know of some performances test of the different ways to get thread local storage in C++?

  - by Vicente Botet Escriba

  I'm doing a library that makes extensive use of a thread local variable. Can you point to some benchmarks that test the performances of the different ways to get thread local variables in C++: C++0x thread_local variables compiler extension (Gcc __thread, ...) boost::threads_specific_ptr pthread Windows ... Does C++0x thread_local performs much better on the compilers providing it?

• Do null SQLite Data fields take up extra memory?

  - by CSharperWithJava

  I'm using the built in sqlite library on the Android platform. I'm considering adding several general purpose fields that users will be able to use for their own custom applications, but these fields will be blank most of the time. My question is, how much overhead will these blank fields add to my database? Do null fields even take up per record memory in sqlite? If so, how much? I don't quite understand the inner workings of a sqlite database.
