  • Is there something like LINQ for Java?

    - by Kb
    Started to learn LINQ with C#. Especially LINQ to Objects and LINQ to XML. I really enjoy the power of LINQ. I learned that there is something called JLINQ a Jscript implementation. Also (as Catbert posted) Scala will have LINQ Do you know if LINQ or something similar will be a part of Java 7? Update: Interesting post from 2008 - http://stackoverflow.com/questions/346721/linq-for-java

  • Does string concatenation use StringBuilder internally?

    - by JamesBrownIsDead
    Three of my coworkers just told me that there's no reason to use a StringBuilder in place of concatenation using the + operator. In other words, this is fine to do with a bunch of strings: myString1 + myString2 + myString3 + myString4 + mySt... The rationale that they used was that since .NET 2, the C# compiler will build the same IL if you use the + operator as if you used a StringBuilder. This is news to me. Are they correct?

  • Sort directory listing using RecursiveDirectoryIterator

    - by Scott Saunders
    I'm using RecursiveDirectoryIterator and RecursiveIteratorIterator to build a file listing tree using code like below. I need to the list to be sorted - either directories then files alphabetically, or just alphabetically. Can anyone tell me how to sort the file list? $dir_iterator = new RecursiveDirectoryIterator($groupDirectory); $iterator = new RecursiveIteratorIterator($dir_iterator, RecursiveIteratorIterator::SELF_FIRST); foreach ($iterator as $file) { // do stuff with $file }

  • programmatically updating iTunes track location

    - by Ben Clifford
    I would like to modify the filesystem path for tracks on itunes programmatically, so that I can apply a string transformation to some of the tracks locations (which are now stored in a different places on the filesystem). I've tried using AppleScript to update the location property of the relevant tracks but I get an end-of-file error when calling "set mytrack's location to ..." I've seen various other hacks online that involve exporting the entire track db, modifying it in XML, and then reimporting it - but that seems to lose too much metadata (such as playlists).

  • Jetspeed 2.2 Nest or render one portlet inside another

    - by David Just
    I have a requirement to build an extensible wizard in a portlet. This wizard will list components that are installed and forward the user to a sub-wizard that is component specific. The requirement is that the components are to be developed by other people and dynamically plugged into this wizard (Jetspeed reboot is okay). I would like to be able to define the components as portlets themselves who's content is rendered into the primary portlet. Has anybody ever done something like this?

  • How to replace the deprecated csc ant task

    - by GrGr
    I have a mixed Java / C# project and use an ant script that contains a csc task to compile the dll. This works, but I get a warning [csc] This task is deprecated and will be removed in a future version [csc] of Ant. It is now part of the .NET Antlib: [csc] http://ant.apache.org/antlibs/dotnet/index.html How can I replace the csc task? I can surely create an exec task calling nant with a project.build file, but that feels completely wrong.

  • Generating db schema from c# class

    - by Niran
    Hi, Is there any other method than nHibernate by wich we can generate db schema from class definition? My classes arn't that complex etc (few one-to-many relations). However I would like to just be able to save my objects in db and recreate schema if needed. I am stuck with .NET 2.0. I am not that particular about performance for this project, I am just lazy to create tables and write save/load code and deel with nHibernate xml. Thanks

  • Learning to compile in xcode

    - by 00PS
    I have started using c++ extensively in school and now my programs are getting to the point where have more than 1 file (i.e. header, driver, implementation file). I don't know enough about software development to understand or get a grasp of how to setup the build process by looking at apple's guides. Could someone walk me through how to compile a simple c++ project with a header and two c++ files in xcode? Do I first need to make a makefile??

  • Makefiles, symlinked folder & relative paths

    - by l.thee.a
    Let say I have the following folders: /A/C /D/B/E /D/B/C (this is a symlink to /A/C created by ln -s) When one of the makefiles tries to use the path /D/B/C/../E it gets a "no file or directory" error. I understand why this happens; /A/E does not exist. However I have to use symlinks to populate the B folder and create the build tree (very long story). Any ideas?

  • What alternatives do I have if I want a distributed multi-master database?

    - by Jonas
    I will build a system where I want to reduce single-point-of-failures, and I need a database. Is there any (free) relational database systems that can handle multi-master setups good (i.e where it is easy to add and remove nodes) or is it better to go with a NoSQL-database? As what I have understood, a key-value store will handle this better. What database system do you recommend for a multi-master (cluster) setup?

I really need some resources, so any help is appreciated.
