• Java: Check what processes are bound to a port?

  - by bguiz

  Hi, I am developing an application in Netbeans, and it is using JavaDB. I can connect to it and execute queries without issues, but for some reason, the "Output - JavaDB Database Process" pane within Netbeans keeps displaying Security manager installed using the Basic server security policy. Could not listen on port 1527 on host localhost: java.net.BindException: Address already in use How do I find out what process is already using, or bound to that port? On Ubuntu Karmic, Netbeans 6.7.1

• What is the difference between C++, Java and JavaScript exception handling?

  - by Dpp

  They are very different kind of languages and the way they handle exception might be pretty different.. How is exception handling implemented and what are the implementation difference within these languages? I am asking this question also because I noticed that C++ exception handling seems to be very slow compared to the JavaScript version.

• String replacement on a whole text file in Python 3.x?

  - by SkippyFire

  How can I replace a string with another string, within a given text file. Do I just loop through readline() and run the replacement while saving out to a new file? Or is there a better way? I'm thinking that I could read the whole thing into memory, but I'm looking for a more elegant solution... Thanks in advance

• GA Framework for Virtual Machines

  - by PeanutPower

  Does anyone know of any .NET genetic algorithm frameworks for evolving instructions sets in virtual machines to solve abstract problems? I would be particularly interested in a framework which allows virtual machines to self propagate within a pool and evolve against a fitness function determined by a data set with "good" outputs given expected inputs.

• SQLAlchemy autocommiting?

  - by muckabout

  I have an issue with SQLAlchemy apparently committing. A rough sketch of my code: trans = self.conn.begin() try: assert not self.conn.execute(my_obj.__table__.select(my_obj.id == id)).first() self.conn.execute(my_obj.__table__.insert().values(id=id)) assert not self.conn.execute(my_obj.__table__.select(my_obj.id == id)).first() except: trans.rollback() raise I don't commit, and the second assert always fails! In other words, it seems the data is getting inserted into the database even though the code is within a transaction! Is this assessment accurate?

• Sharing code between two different git projects

  - by ripper234

  I have two different .Net projects, hosted on github. I would like to create a shared "commons" library for the two projects. How should I structure my repository to facilitate this sharing? Ideally, a change in this common library in one project could easily be pushed into the other project. I prefer to keep the code itself editable from the two projects (within Visual Studio), and not include it as a library. Are there best practices for this?

• How can I check if a powershell script is signed from the managed API?

  - by James Berry

  I want to execute a powershell using the .net Powershell SDK. I have this working fine. Before I execute it I want to check that the script has been signed by my code signing certificate - this is easy enough to do from within powershell itself using Get-AuthenticodeSignature but I would like to do this in code before choosing to execute this script.

I created a really simple NUnit test in VS and this also doesn't show so I know it's not something weird in my existing tests. Any ideas?

• Silverlight penetration rate

  - by sthg

  Duplicate of: Silverlight Install Base - How big is it? Hi, Anyone knows the penetration rate (in %) for all North-American internet users with the Silverlight plugin installed? Been looking all around, but couldn't find any comprehensive numbers. I'm looking for General Public penetration rates, not only within the dev community. Something close to Adobe's flash version penetration stats would be great.

• Windows Media Center, setting referer header

  - by Sha Le

  Hi I asked this question in SuperUser, posting here as well (http://superuser.com/questions/225671/windows-media-center-setting-referer-header). Is there a way to add REFERER header for any RTSP streams within Windows Media Center, I learned that REFERER header is only added when Windows Media Player is in a embed state. But I want to know that's true and also is there any plugin/addon. Thanks in advance.

• Is it more efficient (Performance) to store the CFC in application variables OR instance the CFC on the page call?

  - by Mitchell Guimont

  Hello, I'm working on a ColdFusion dynamic website. For this website, there are a lot of CFCs and a lot of functions within each CFC. Would it be more efficient to store an instance of the CFC in an application variable, then to instance each CFC separately on each page load. For each page, at most 2 separate CFCs get called. I'm also interested in how performance will be effected when requests increase (Stress). Thanks!

• How to disable customization for the TabBar?

  Hey, within my App it should be forbidden to edit (customize) the TabBar. This means there should be no edit button and no other possibility to change the order of the items.

• Can I configure a resource path that contains java source files in eclipse?

  - by tangens

  Motivation In eclipse I'd like to configure a path as a resource path. This path contains some java files that I only want to handle as resources, i.e. I don't want eclipse to try to compile these files. I only want to read them as resources from within junit tests. Question Is there a way to configure eclipse so it won't try to compile the java files it found there?

  Now, this is simple enough when the numbers are small, but numbers like "9223372036854775807" are too large for parseInt(). I'm not sure how to do this within the Google docs script editor, which doesn't seem to allow for external classes.
