• What programming languages are good for statistics?

  - by Jason Baker

  I'm doing a bit more statistical analysis on some things lately, and I'm curious if there are any programming languages that are particularly good for this purpose. I know about R, but I'd kind of prefer something a bit more general-purpose (or is R pretty general-purpose?). What suggestions do you guys have? Are there any languages out there whose syntax/semantics are particularly oriented towards this? Or are there any languages that have exceptionally good libraries?

• jquery - if else if?

  - by YesThatsRight

  I've been trying to figure out the syntax for an if / else if statement in jquery, but googling gives me mixed messages... There are some sites that say I need a plugin, and others that suggest that it's already possible. Trying those suggestions give me jquery errors in the jquery.js file, so I'm wondering, do I need a plugin or not? Does someone have an example of an if () { //do something } else if () { //do something else } else { //do something } in jquery?

• Are there any FREE Xaml Diff/Merge tools available?

  - by Ahikam

  I am searching a free diff tool with support of native syntax and markup for XAML, but failed to find one. I like Altova's DiffDog but it's paid. CodeCompare is an useful tool. It has some worth with its integration into VisualStudio and usage of native editors. It's a perfect solution for XML! However, it does not support XAML editors. Who can recommend a diff tool for XAML?

• Semantic #region usage

  - by Luca

  What's your opinion about using #region folding using application semantic, instead of folding for "syntax". For example: #region Application Loop #region User Management #region This Kinf of stuffs instead of #region Private Routines #region Public Properties #region ThisRoutine // (Yes, I've seen this also!) In this logic, I'm starting fold even routine bodies. I'm starting to love #region directive (even using #pragma region when using C++!).

• How do I get Aptana to recognize .jspf files?

  - by Keith Bentrup

  How do I get Aptana to recognize .jspf files? I'd like to have syntax highlighting for .jspf files. I'm sure there's a preference/config option or an xml file to edit, but I'm not finding it. I assume it's similar to the eclipse process, so I'm tagging eclipse, too. If it's not, I'll remove the tag.

• What does this mean?

  - by LeonixSolutions

  I found this in some code examples while googling : $sql = 'INSERT INTO users (username,passwordHash) VALUES (?,?)'; it's new to me, but I would guess that it a substitution method and equivalent to $sql = "INSERT INTO users (username,passwordHash) VALUES ($username,$passwordHash)";` or $sql = 'INSERT INTO users (username,passwordHash) VALUES (' . $username . ',' . $passwordHash . ')';` would that be correct? Is it an actual PHP syntax, or was he just trying to simplify his example?

• Why cast null before checking if object is equal to null?

  - by jacerhea

  I was looking through the "Domain Oriented N-Layered .NET 4.0 Sample App" project and ran across some code that I do not understand. In this project they often use syntax like the following to check arguments for null: public GenericRepository(IQueryableContext context,ITraceManager traceManager) { if (context == (IQueryableContext)null) throw new ArgumentNullException("context", Resources.Messages.exception_ContainerCannotBeNull); Why would you cast null to the type of the object you are checking for null?

• Multiple Regex on String

  - by George

  How can I apply multiple regexs to a single string? For instance, a user inputs the following into a text area: red bird blue cat black dog and I want to replace each carriage return with a comma and each space with an underscore so the final string reads as red_bird,blue_cat,black_dog. I've tried variations in syntax along the lines of the following so far: function formatTextArea() { var textString = document.getElementById('userinput').value; var formatText = textString.replace( new RegExp( "\\n", "g" ),",", new RegExp( "\\s", "g"),"_"); alert(formatText); }

• How to store the hostname in a variable in a .bat file?

  I would like to convert this /bin/sh syntax into a widely compatible Windows batch script: host=`hostname` echo ${host} How to do this so that it'll work on any Windows Vista, Windows XP, and Windows 2000 machine? To clarify: I would then like to go on in the program and use the hostname as stored in the variable host. In other words, the larger goal of the program is not to simply echo the hostname.
