• Capistrano deploying to different servers with different authentication methods

  - by marimaf

  I need to deploy to 2 different server and these 2 servers have different authentication methods (one is my university's server and the other is an amazon web server AWS) I already have running capistrano for my university's server, but I don't know how to add the deployment to AWS since for this one I need to add ssh options for example to user the .pem file, like this: ssh_options[:keys] = [File.join(ENV["HOME"], ".ssh", "test.pem")] ssh_options[:forward_agent] = true I have browsed starckoverflow and no post mention about how to deal with different authentication methods this and this I found a post that talks about 2 different keys, but this one refers to a server and a git, both usings different pem files. This is not the case. I got to this tutorial, but couldn't find what I need. I don't know if this is relevant for what I am asking: I am working on a rails app with ruby 1.9.2p290 and rails 3.0.10 and I am using an svn repository Please any help os welcome. Thanks a lot

• Service and Web Reference crashes Visual Studio

  - by CatZ

  When I move the mouse over any of these two or right click any of them Visual Studio crashes with the following message in the event log: Felet uppstod i programmet med namn: devenv.exe, version 9.0.30729.1, tidsstämpel 0x488f2b50 , felet uppstod i modulen med namn: ntdll.dll, version 6.1.7600.16385, tidsstämpel 0x4a5bdb3b Undantagskod: 0xc0000374 Felförskjutning: 0x000cdcbb Process-ID: 0xef4 Programmets starttid: 0x01cb07b7f1bd036d Sökväg till program: C:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\IDE\devenv.exe Sökväg till modul: C:\Windows\SysWOW64\ntdll.dll Rapport-ID: 46c92fc7-73ab-11df-b110-002481038dc3 Unfortunately it's the same thing in Visual Studio 2010 as it is in Visual Studio 2008.

• Project links in RAD Studio Welcome page do not work

  - by vcldeveloper

  Hi, As you know, welcome page in RAD Studio shows a list of recent projects, and you can open each project by clicking on its name. My problem is that if the project is located somewhere My Documents folder, then the link in welcome page does not work! It works fine for projects which are located outside My Documents, but no links to anything inside My Documents work. It's been a while I am having this problem both in RAD Studio 2009 and RAD Studio 2010 on Windows Vista and Windows 7 (64-bit). I tried running the IDE as administrator to see if it works, but it didn't. I think it must be something related to IE security settings. Any idea? Thanks

• How to know the root device size of some public AMI?

  - by red23jordan

  Since I do not want to pay money for my testing, the free limit size is 10G. I can know the root device root for some default AMI such as Amazon Linux AMI 2012.03 The Amazon Linux AMI 2012.03 is an EBS-backed, PV-GRUB image. It includes Linux 3.2, AWS tools, and repository access to multiple versions of MySQL, PostgreSQL, Python, Ruby, and Tomcat. Root Device Size: 8 GB And the last row displayed 8GB. However, if I find AMI in Community Page, it does not show the root device size. Can anyone know how to use the instance such as centOS that is not provided by default but it is under 10GB so that I can still free use?

• How to automate a build for a Visual FoxPro project?

  - by jpierson

  I'm interested in figuring out how to automate a build from Visual FoxPro similar to how we can build .NET projects from the command line using MSBuild. It seems that it is possible to pass command line arguments to VFP.exe which may include the ability to specify some initial startup prg that runs however it is unclear how well starting up the IDE will work from non-interactive accounts such as the Network Service on Windows which is likely where an automated build would run. Has anybody attempt this before or read about anybody attempting to script a VFP build like this? I would be grateful for any pointers that may lead me to a solution.

• Eclipse RCP application launcher not working properly in Arabic

  - by el_eduardo

  I have an RCP application which I build using the .product file and PDE. In my product file I create a binary launcher for different applications to provide convenience to the user. It all works fine except when testing in Arabic languages. In Arabic the application starts and it actually shows the Arabic characters that I mocked for testing but, it does not mirror. That said, if I invoke the launcher and pass the -nl switch launcher.exe -nl AR Then it mirrors. Also if I launch from the IDE with the target platform environment set to AR it mirrors too. I am shipping the bidi plugins for jface and swt (along with the NL plugins) and for the platform delta packs... Does anynone know what could be wrong with the laucher?

  Hello all, I am trying to connect to a SVN server in order to import my project into it with svn+ssh authentication method.

• How to choose a integer linear programming solver ?

  - by Cassie

  Hi all, I am newbie for integer linear programming. I plan to use a integer linear programming solver to solve my combinational optimization problem. I am more familiar with C++/object oriented programming on an IDE. Now I am using NetBeans with Cygwin to write my applications most of time. May I ask if there is an easy use ILP solver for me? Or does it depend on the problem I want to solve ? I am trying to do some resources mapping optimization. please let me know if any further information is required. Thank you very much, Cassie.

• Do I really need cmake for build automation?

  - by PMiller

  I'm currently investigating cmake to allow automatic building on the Win32 platform. For all runtimes and libraries I'd like to build, Visual Studio (2008/2010) projects do allready exist. I've come across cmake, but I'm unsure if I really need it. As the documentation says, cmake generates VS projects and they then can be built e.g. using MSBuild. As the projects itself allready do exist (and build nicely via the IDE or MSBuild on the cmd line), what do I need and use cmake for? Just for directory/project folder traversal? Build failure reporting? Regards, Paul

• What useful GDB scripts have you used/written?

  - by nik

  People use gdb on and off for debugging, of course there are lots of other debugging tools across the varied OSes, with and without GUI and, maybe other fancy IDE features. I would like to know what useful gdb scripts you have written and liked. While, I do not mean a dump of commands in a something.gdb file that you source to pull out a bunch of data, if that made your day, go ahead and talk about it. Lets think conditional processing, control loops and functions written for more elegant and refined programming to debug and, maybe even for whitebox testing Things get interesting when you start debugging remote systems (say, over a serial/ethernet interface) And, what if the target is a multi-processor (and, multithreaded) system Let me put a simple case as an example... Say, A script that traversed serially over entries to locate a bad entry in a large hash-table that is implemented on an embedded platform. That helped me debug a broken hash-table once.

• jTabbedPane opens different tab on loading

  - by Santeron

  Hey mates, First of all I'm using netbeans as my IDE and I don't know if this is causing it. When I run my program (even if I have build it and run the .jar) I think it selects the tab that was previously selected (before quiting). So if for example I close the app with the third tab selected, it starts up with that selected again. Is there a known solution for this? The selectedIndex property on the jTabbedPane is set to 0. Shouldn't this property be the default onLoad value? Thx in advance, Jimmy PS. BTW for some reason it didn't submit my question in Opera (?)

• Parse HTML file to grab all ID and Classes for a CSS file

  - by iamfriendly

  Hey all, A short while ago, I'm fairly certain I came across an application (or perhaps a plugin for Coda - the IDE I use) which quickly parses a html document and then spits out all of the elements with IDs and Classes for me to use in a CSS file. Having fully 'got into' zen coding - using the wonderful TEA plugin for Coda, I'm now hot on the heels of this app/plugin again. I've tried and failed miserably at hunting through Google, but have come up completely empty handed. Does anyone know of anything which can do this? Happy New Year everyone!

• Generating a Call Hierarchy for dynamicly invoked method

  - by Maxim Veksler

  Hello, Today's world of dynamic invoke, reflection and runtime injection just doesn't play well with traditional tools such as ctags, doxygen and CDOC. I am searching for a method call hierarchy visualization tool that can display both static and dynamic method invocations. It should be easy to use, light during execution and provide helpful detailed information about the recorded runtime session. Now I guess Callgrind could be considered a valid solution for the family C. What tool / technique could you suggest to create a call graph for both static and dynamic method invocation for JVM based bytecode? The intended end result is a graphical display (preferably interactive) which can show path from main() to each method that was invoked. During research for this post I stumbled upon javashot, it seems that this is the kind of approach I'm aiming at, I would prefer that this would be integrated into a kind of profiler or alike which than can be used from within my IDE (Eclipse, IntelliJ, Netbeans and alike). Thank you, Maxim.

• trying to decide between asp.net and jsp

  - by Amir

  Hey Guys, I am wondering if anyone can shed some lights on the situation. I am about to start a project and trying to figure out what solution is best to go with asp.net or java jsp pages I have personally worked alot with .net and am really happy with the framework and Visual studio as IDE I find it easy to work with and there is a massive community support behind .net, i can get alot done quickly I have not every written anything use java jsp, there will be a learning curve here , so my experience is limited here. however after seeing jira i am very impressed with its capabilities, it has changed alot since the old days ( java 1.2 ) that i used to work with, and the fact that it runs under linux is a huge plus, so i am trying to decide is the learning curve, worth the price ? so given the situation above what would you recommended? Thanks, Amir

  I'm starting down the road of Android Development. At this point I'm looking for some insight from other developers who have been doing 'droid development and have some experience to share with someone who is just starting out.

• ANTLR parser hanging at proxy.handshake call

  - by Peter Boughton

  I am attempting to get a basic ECMAScript parser working, and found a complete ANTLR grammar for ECMAScript 3, which appears to compile ok and produces the appropriate Lexer/Parser/Walker Java files. (Running inside ANTLR IDE plugin for Eclipse 3.5) However, when actually trying to use it with some simple test code (following guide on ANTLR wiki), it just hangs when trying to create the parser: CharStream MyChars = new ANTLRFileStream(FileName); // FileName is valid ES3Lexer MyLexer = new ES3Lexer(MyChars); CommonTokenStream MyTokens = new CommonTokenStream(MyLexer); MyTokens.setTokenSource(MyLexer); ES3Parser MyParser = new ES3Parser( MyTokens ); // hangs here ES3Parser.program_return MyReturn = MyParser.program(); I've tracked down the problem to inside the ES3Parser constructor, where it's calling the function proxy.handshake() - before this line I can successfully do System.out.println("text") but after it I get nothing. So, how do I go about finding out why it's hanging, and stopping it - or even just bypassing this section (can/should I disable debugging?) - so long as that lets it work and allows me to get on with doing useful stuff.

• VSS to TFS Migration - Persist User on check-in actions

  - by Adam Jenkin

  I am using the VSSConveter.exe tool to import from VSS6 (using 2005 ide) to TFS2008. I have run analyze (no errors) and migrate WITH a user mapping file (containg the vss/domain user mappings) I would like to persist in tfs the check-in user of the file, currently the check-in user for all versions of file shows as admin (the account im running the import with), the origional check-in user is appended to the check-in comment. For example:- TestFile.aspx in VSS Check in ver: 1 - User:Adam - Comment:TEST1 Check in ver: 2 - User:James - Comment:TEST2 Check in ver: 3 - User:Joel - Comment:TEST2 After import into TFS Check in ver: 1 - User:mydomain\Admin - Comment:TEST1 (Commited by Adam) Check in ver: 2 - User:mydomain\Admin - Comment:TEST2 (Commited by James) Check in ver: 3 - User:mydomain\Admin - Comment:TEST2 (Commited by Joel) In TFS I want the user to show as the correct domain user as configured in my user mapping file. Is this possible, or is this just how the VSSConverter program works?

• How to integrate pep8.py in Eclipse?

  - by DZPM

  A little background: PEP 8 is the Style Guide for Python Code. It contains the conventions all python programmers should follow. pep8.py is a (very useful) script that checks the code formating of a given python script, according to PEP 8. Eclipse is a great IDE. With the Pydev extension, it that can be used to develop Python I run pep8.py manually when I'm scripting, but with bigger projects I prefer to use Eclipse. It would be really useful to integrate pep8.py in Eclipse/Pydev, so it can be run automatically in all the files in the project, and point to the lines containing the warnings. Maybe there is an obvious way to do it, but I haven't found it yet. Question is: How to integrate pep8.py in Eclipse?

• Scope of variables inside anonymous functions in C#

  - by Vinod

  I have a doubt in scope of varibles inside anonymous functions in C#. Consider the program below: delegate void OtherDel(int x); public static void Main() { OtherDel del2; { int y = 4; del2 = delegate { Console.WriteLine("{0}", y);//Is y out of scope }; } del2(); } My VS2008 IDE gives the following errors: [Practice is a class inside namespace Practice] 1.error CS1643: Not all code paths return a value in anonymous method of type 'Practice.Practice.OtherDel' 2.error CS1593: Delegate 'OtherDel' does not take '0' arguments. It is told in a book: Illustrated C# 2008(Page 373) that the int variable y is inside the scope of del2 definition. Then why these errors.

• exe files and Python

  - by Sorush Rabiee

  i have some questions about python: 1- How to build .exe files from .py files? 2- How to run a program with arguments and receive the result by python code? 3- How to load .NET library in python code (or write python in VS.NET IDE [!?])? 4- is built-in integer of python 3.1 something like a string? it calculates 200! in less than one second and calculates 2^1 to 2^7036 (by a simple recursive algorithm & writing them to a text file) with a 1.75GHz cpu in 4 minuets, so if it is a string, how it can be so fast like this? is there a great difference between memory type and logical calculation of python with c++? 5- what is the best python practice? how can i be an expert?

• Is using Capistrano for user maintenance tasks on university lab feasible?

  - by danielkza

  I've been looking around for tools to replace some legacy scripts for creating and maintaining accounts in a university computer lab ecosystem consisting of things like: LDAP and Kerberos for authentication User home storage and web pages Entries on an SQL database Printing quotas Mailing lists, etc. I'd also like to automate machine and VM membership for Kerberos and Puppet if possiible. I've found Capistrano, and while the basic principle of running tasks on remote hosts through SSH seems to fit, and the DSL in Ruby looks quite nice, I've found most documentation is related to application deployment, not generic tasks. I'm also not aware of any good way to parameterize tasks so I can pass on the user information for creation. Is something about Capistrano I am missing, or is it not the correct tool for this job? Are there any more userful alternatives?

• Connecting to SQL Server with Visual Studio Express Editions

  - by tlianza

  I find it odd that in Visual C# 2008 Express edition, when you use the database explorer, your options are: 1) Microsoft Access 2) SQL Server Compact 3.5, and 3) SQL Server Database File. BUT if you use Visual Web Developer 2008 Express, you can connect to a regular SQL Server, Oracle, ODBC, etc. For people developing command-line or other C# apps that need to talk to a SQL Server database, do you really need to build your LINQ/Data Access code with one IDE (Visual Web Developer) and your program in another (Visual C#)? It's not a hard workaround, but it seems weird. If Microsoft wanted to force you to upgrade to Visual Studio to connect to SQL Server, why would they include that feature in one of their free IDEs but not the other? I feel like I might be missing something (like how to do it all in Visual C#). Thanks! Tom
