• What's the recommended hashing algorithm to use for stored passwords?

  - by Hissohathair

  Given the known weaknesses of MD5 and the recent (May 2009) weaknesses discussed in SHA1, how should new programs be salting & hashing their passwords? I've seen SHA-256 and SHA-512 suggested. Programming predominately in Ruby on Rails and using PostgreSQL -- but other languages and environments might also have to calculate password hashes.

• Generating .po/.mo files

  - by Echilon

  I have a database full of translations I'd like to generate either .po or .mo files. I'm using C#, but I could also port an implementation from PHP if one exists. I can't find any examples in any languages using anything other than GNUs gettext utilities. Does anyone know of one?

• Embed python interpreter in a python application

  - by MatToufoutu

  Hi, i'm looking for a way to ship the python interpreter with my application (also written in python), so that it doesn't need to have python installed on the machine. I searched google and found a bunch of results about how to embed the python interpreter in applications written in various languages, but nothing for applications writtent in python itself... I don't need to "hide" my code or make a binary like cx_freeze does, i just don't want my users to have to install python to use my app, that's all. Thanks.

• Actor model to replace the threading model?

  - by prosseek

  I read a chapter in a book (Seven languages in Seven Weeks by Bruce A. Tate) about Matz (Inventor of Ruby) saying that 'I would remove the thread and add actors, or some other more advanced concurrency features'. Why and how an actor model can be an advanced concurrency model that replaces the threading? What other models are the 'advanced concurrency model'?

• Invoking shell commands from Squeak or Pharo

  - by squeaknewb

  How can you invoke shell commands from Squeak and Pharo? Do these environments have anything in them like the system() function in certain unix languages to run external shell commands, or the backticks (can't make them here do to the editor, but what you get when you push the key left of "1" and above "TAB") to capture the output of commands?

• translating Ecmascript (Java,javascript,Actionscript) knowledge to Objective C

  - by eco_bach

  Hi Newcomer to Objective C and trying to translate concepts and sytax I know from ecmascript based languages to Objective C. Is it proper to think of the .h header file in ObjectiveC as an Interface in Actionscript? Lets take the following code example in Objective C which calls a method containing 2 arguments [myTextObject setString: @"Hello World" color: kWhiteColor]; In Actionscript(or javascript) would this be the same as calling 2 accessor methods on 'myTextObject'? ie myTextObject.setString("Hello World") myTextObject.color(kWhiteColor);

• Most Up-To-Date C# Duck-Typing Library

  - by Anton Gogolev

  The title says it all, basically. What is the current state of the art on duck typing for C# below version 4.0? I know about Duck Typing Project, I know that BLTookit has something to that end, but I'd like to know if I'm missing something really wicked apart from DLR languages and C# 4.0. The inevitable:

• .Net Library for parsing source code files?

  - by Jörg Battermann

  Does anyone know of a good .NET library that allows me to parse source code files, but not only .NET source code files (like java, perl, ruby, etc)? I need programmatic access to the contents of various source code files (e.g. class/method /parameter names, types, etc.). Has anyone come across something like this? I know within .NET it is reasonably possible and there are some libraries out there, but I need that to be abstracted to more types of programming languages.

• What are codepad.org's Perl runner limitations?

  - by Lemurik

  Sometimes I see people use http://codepad.org as a way to quickly run/test their Perl snippets (it supports doing that with a wide variety of languages, from C to Scheme to Perl). It's pretty obvious that there must be some limitations as to what code/features can be tested with codepad - does anyone know what those limitations are for Perl runner? I'll get the ball rolling on my own observation: not every CPAN module is available :(

Not to offend anyone, please post code samples in a language like c#, python, javascript, ruby etc. I am sorry, I do not understand functional languages yet.

• API for parse/update UNIX configuration files

  - by Chen Levy

  Unix configuration files come in all shapes and forms. I know that Webmin has a Perl API that makes it easy to parse and modify most common configuration pro grammatically, while preserving changes that might have been made by hand. Are there any other libraries that has similar functionality, perhaps for other languages (Python, Ruby, C, C++, etc)?
