  • How to use cscope in Visual Studio?

    - by rahulthewall
    Hello all, I am working with Visual Studio (2008 edition) for the first time. Used to programming in a Unix environment, I have become quite used to cscope and vim. For my current project, I really need cscope. I was wondering if there is any way I could use cscope on Visual Studio - or use cscope in Windows. Or if there is another tool which does this job .. Thanks Rahul

  • On what platform did these popular programming languages originate?

    - by speciousfool
    Perhaps you know the story of HTTP and HTML being developed on a NeXT computer. I am curious which platform served as the first home for these programming languages: Ada C C++ C# D Erlang Fortran Haskell Java Javascript Lisp Logo MATLAB ML Perl PHP Prolog Python R Ruby Scheme SQL Smalltalk I thought it might be interesting to reflect on how the machine and operating environment lead to different design decisions. Or to see if some architecture or operating system variant was particularly fruitful for programming language development. A question for the historians among us.

  • Starting old computer - nothing shown on screen at boot

    - by Jonas
    I'm trying to start an about 10 years old PC computer. But nothing is shown on the screen, and it beeps everytime I press a key on the keyboard. I can press Ctrl+Alt+Del to reboot the computer. The monitor is newer and seem to work with other computers. I don't see anything from POST/BIOS at start or later. I have tried to change to another graphic card, but it didn't change anything. What can I do to solve this problem? Update: I have now tried with another computer (the one where the "another graphic card" came from) and I got the same problem. I doesn't show anything on the screen. Both these computers had a GeForce2 MX 400 graphic card. I tried with another computer screen it didn't work - it was showing "signal out of range". So is the graphic card GeForce2 MX 400 too old for newer TFT-monitors? I tried with a third computer so I know that the monitors are working, and both monitors work fine with that computer.

  • Running OpenMPI on Windows XP

    - by iamweird
    Hi there. I'm trying to build a simple cluster based on Windows XP. I compiled OpenMPI-1.4.2 successfully, and tools like mpicc and ompi_info work too, but I can't get my mpirun working properly. The only output I can see is Z:\orterun --hostfile z:\hosts.txt -np 2 hostname [host0:04728] Failed to initialize COM library. Error code = -2147417850 [host0:04728] [[8946,0],0] ORTE_ERROR_LOG: Error in file ..\..\openmpi-1.4.2 \orte\mca\ess\hnp\ess_hnp_module.c at line 218 -------------------------------------------------------------------------- It looks like orte_init failed for some reason; your parallel process is likely to abort.

Can anyone help me? Upd2: Error code -2147024891 might be WMI error WBEM_E_INVALID_PARAMETER (0x80041008) which occures when one of the parameters passed to the WMI call is not correct. Does this mean that the problem is in OpenMPI source code itself? Or maybe it's because of wrong/outdated wincred.h and credui.lib I used while building OpenMPI from the source code?

  • How to organize Drupal templates?

    - by picardo
    I created a few custom templates while modifying a theme (Acquia Prosper), and my usual practice is to put all my templates in this fashion: theme-name/templates/page/page-front.tpl.php But it didn't quite work this time. So I'm wondering why. I looked through the templates.php for a clue, but there is nothing there. My base theme where I used this organization was genesis, and in that theme it seems to work, but not in Acquia Prosper. Can anyone shed some light on this?

  • Data files from development machine to iOS device

    - by StoneBreaker
    My app has created a bunch of data files as development has progressed through the simulator. Their location is obtained by this function: NSString *pathInDocumentDirectory(NSString *fileName) { NSArray *documentDirectories = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentDirectory = [documentDirectories objectAtIndex: 0]; return [documentDirectory stringByAppendingPathComponent: fileName]; } The files are now required on the device as testing of the app is moving from the simulator to actual devices. How do I transfer the data files from my current working environment to the devices?

  • Testing code that uses SoftReference<T>

    - by bmargulies
    To get any code with SoftReference<T> to be fully tested, one must come up with some way to test the 'yup, it's been nulled' case. One might more or less mock this by using a 'for-test' code path to force the reference to be null, but that won't manage the queue exactly as the GC does. I wonder if anyone out can share experience in setting up a repeatable, controlled, environment, in which the GC is, in fact, provoked into collecting and nulling?

  • Run shell command from jar?

    - by phineas
    The usual way to call a shell command from java is something like that: Process process = Runtime.getRuntime().exec(command); and works usually fine. But now I've exported my project to an executable jar file and callig shell commands doesn't work any more. Are there any explanations, solutions or workarounds for this problem? phineas -- edit: even keyboard interrupts (ctrl+c; ctrl+d) aren't recognized. terminal input won't work after killing java

  • Does Ruby Version Manager interfere with the system scripts on Dream Linux?

    - by stephemurdoch
    Since Dream Linux has built in support for Ruby, I'm assuming it will work well as a Rails development environment, but I'm wondering if Ruby Version Manager will interfere with the system version of Ruby. Generally, when I use RVM, I disable/ignore the system version. How will the Dream Linux OS system scripts that are written in Ruby react to the presence of RVM? If I can't use RVM on Dream Linux, how easy is it to upgrade to newer versions of Ruby, without frazzling the system?

  • Dropbox picture sync: Skip RAW files?

    - by Steven Lu
    I like the convenience of having Dropbox keep track of my photos because it tends to work with my devices over 3G (I am often tethering to my phone with my iPad and Macbook) as well as Wifi, but it's a waste of network traffic to sync the raw files from my camera or memory card. It clutters up the dropbox list and the files are just huge. Is there a way to configure the Dropbox client so that it ignores a certain file extension for the picture sync? Also, I suspect that if I just go and delete the raw files, that the next time I plug in the memory card and tell Dropbox to sync, it will re-download the raw files. Which would be terribad. I could switch to iCloud for Photo Stream, I suppose, but there will be no access via 3G that way. And I've already got years of experience with Dropbox so I know it's going to just work. I think any method that works for filtering files to exclude from sync on Dropbox in general should work here too. Edit: Wow there are 19k votes for this exact request.

  • Drupal site requires a higher memory limit after migration? Why?

    - by oalo
    Hello. We have a website which had a previous memory limit of 12 MB (12 MB in php.ini, and 16 MB in settings.php) and worked previously. After moving to a new server it started giving memory limit errors and displaying half-blank screen. We increaded the limit in both files (php.ini and settings.php) and now it works, but I dont understand how is it possible that now it needs a considerably larger amount of memory (it used to work with 12 MB, now it cont work with less than 20 MB).

  • Configure X connections over TCP without using an X connection

    - by Darren Cook
    I want to run a GUI application on a remote machine I only have ssh access to. I don't need to, or want to, see the GUI window. (I know I could use something like ssh -C -X remote_server if I wanted the GUI to be on my client.) I know X is running on the remote machine, as ps shows this: root ... /usr/bin/Xorg :0 -br -audit 0 -auth /var/gdm/:0.Xauth -nolisten tcp vt7 I set DISPLAY=:0.0 but I then get "Xlib: connection to ":0.0" refused by server" when I try to use it. At Get remote x display working in linux without ssh tunneling and Xserver doesn't work unless DISPLAY=0.0 I see the advice to use gdmsetup to allow X to listen on TCP. But, gdmsetup is a GUI application! And trying to run it over ssh -X did not work ("X11 connection rejected because of wrong authentication"). So, is there a text file I can edit to remove -nolisten? And, after editing it, how do I safely restart X, remotely? (There is other stuff running on this machine, so requesting a reboot is possible, but undesirable.) If not, should gdmsetup be able to run over ssh and I should persevere in that direction? UPDATE: I had to do the ssh -X session as root (ssh as a normal user, then sudo or su, does not work.) So, I did the edit with gdmsetup. I then restarted X with gdm-restart. I've also done xhost + from that ssh -X session. The ps line no longer shows the -nolisten tcp part. But still no luck connecting to it, with either DISPLAY=:0 or DISPLAY=localhost:0

  • How do you remind your Scrum Product Owner about his promises/actions?

    - by Felix Ogg
    ** EDIT: Rephrased the question to re-focus ** Our Scrum team meets as seldomly as possible, but we meet with the product owner every chance we get. We track everyone's agreed action points (particularly theirs). We are 100% agile, but our product owner lives in traditional world, we remain off-site. We facilitate him in crossing over to our fast-paced world. There's not much wrong. The team and the PO are in good spirits. PO is present at every meeting and positively energized. Just imagine this person as a 70 year old, slow grandpa, who is forgetful, yet kind. In reality he isn't, but he is used to a working environment (public servants) that is much slooooower. Manyana-manyana etc. It is frustrating for my team to cooperate: PO lives in a non-prioritized environment, and everyone in it has learned the productivity-technique of NGTD (Not Getting Things Done). He WANTS to, it's just that he forgets or 'sinks' somewhere along the away. We have experimented with a text file, maintained by the Scrum master (low-tech), which he broadcasts by e-mail every day JIRA, our issue tracker. Turns out this is nice for programmers, but too steep for 'regular people' I Googled for Issue tracking webtools but came up empty handed: All tools are aimed at IT issue tracking, instead of meeting action point tracking/planning for mere mortals. I did find TODO-lists like RememberTheMilk, but they don't track comments, and - to be honest - I doubt we could get our product owner to use it (too complicated). We have three requirements: Register action points, assign to a team member and a deadline Offer anyone to 'comment' on progress of any action point Do not build our own tool from scratch We do not need: - impressive authorization models, - multi-project, - workflow, - crosslinking. Is there any trick/tool you use to assist your product owner 'fly' like the rest of the rest of the team? Communication before tools I agree with the general consensus that one should not try to apply technology to a communication problem, however in this case I am merely looking for a tool to save me time in setting up prioritized lists. I found www.thymer.com today, may be what I am looking for. The guys are cool. It is getting rather feature-bloated though.

  • Injection of class with multiple constructors

    - by Jax
    Resolving a class that has multiple constructors with NInject doesn't seem to work. public class Class1 : IClass { public Class1(int param) {...} public Class1(int param2, string param3) { .. } } the following doesn’t seem to work: IClass1 instance = IocContainer.Get<IClass>(With.Parameters.ConstructorArgument(“param”, 1)); The hook in the module is simple, and worked before I added the extra constructor: Bind().To(); Thanks in advance...

  • How to restrict code from developers

    - by Kelvin
    My company is planning in hiring outsourcers to work for us, but concerned to give whole existing code to outside world. What is the proper way to deal with security of sharing code in such cases? Is it possible to restrict part of code for developers? So each of them could work on their project without having access to whole repository. P.S. The code we have is very integrated, and its hard to extract "one module", each module can use files from different locations. Thanks in advance

  • Using UNC path as collections location in Mecurial IIS6 Server2003

    - by Chris M
    I'm running the latest Mercurial and Python 2.6; IIS6 is using the wildcard ISAPI method to attach the site to the Mecurial hgwebdir_wsgi [paths] \ = \\COMP3254\TestRepo\* [web] baseurl = / allow_push = * push_ssl = false style = monoblue The setup works perfectly if I reference the local drive E:\repo* but doesnt work if I specify the network as above; I've given the server (MERCDEV01$) full permissions on the shared folder on COMP3254, I can't think of any other reason it wouldn't work. Any ideas?
