• Problem doing SVN Vendor Branch - merge

  - by Gyan

• Shortcuts and MSI updates

  - by Filip Navara

  We have an installer for application that is compiled using WiX and each version is updated using a new setup package. The installer creates advertised shortcut in Start menu and users often copy this shortcut to desktop or other location. During an application update a major upgrade is performed and the old shortcuts are removed, which causes the ones copied by users to disappear. This causes a major annoyance to the users. Is there a way to update advertised shortcuts when doing MSI major upgrade (ie. different product code)? Or, is there a way to allow minor updates by just running the setup.msi file (without passing a REINSTALLMODE option on the command line)? Or, is the only way to solve this problem to use non-advertised shortcuts?

• Where is the help.py for Android's monkeyrunner

  - by Keyboardsurfer

  Hi, I just can't find the help.py file in order to create the API reference for the monkeyrunner. The command described at the Android references monkeyrunner <format> help.py <outfile> does not work when i call monkeyrunner html help.py /path/to/place/the/doc.html. It's quite obvious that the help.py file is not found and the monkeyrunner also tells me "Can't open specified script file". But a locate on my system doesn't bring me a help.py file that has anything to do with monkeyrunner or Android. So my question is: Where did they hide the help.py file for creating the API reference?

• Make errors - can the gcc compiler warnings prevent a C file from being compiled into an object file

  - by Xolstice

  I'm trying to compile a wireless network card driver for my Linux box and I ran into a problem with the Make command. During the compilation process I normally see warnings on some of the C files that being are compiled; despite the warnings these files were still able to be compiled to an object file. When the Make process comes to a file called rtmp_wext.c however, the compiler generates a large number of warnings and then the whole Make process stops and returns an exit status of error 1, i.e. make: *** [rtmp_wext.o] Error 1. Usually I see an error with the C file for compilation to halt. This is the first time where it seems compiler warnings are preventing the file from being turned into an object file; is this possible or is something else the cause for the unsuccessful compilation?

• MD5 hash differences between Python and other file hashers

  - by Sam

  I have been doing a bit of programming in Python (still a n00b at it) and came across something odd. I made a small program to find the MD5 hash of a filename passed to it on the command line. I used a function I found here on SO. When I ran it against a file, I got a hash "58a...113". But when I ran Microsoft's FCIV or the md5sum.py in \Python26\Tools\Scripts\, I get a different hash, "591...ae6". The actual hashing part of the md5sum.py in Scripts is m = md5.new() while 1: data = fp.read(bufsize) if not data: break m.update(data) out.write('%s %s\n' % (m.hexdigest(), filename)) This looks functionally identical to the code in the function given in the other answer... What am I missing? (This is my first time posting to stackoverflow, please let me know if I am doing it wrong.)

• Do I need a view controller for MVVM-light in Silverlight?

  - by Stefan de Vogelaere

  I have the following question regarding MVVM light: what "drives" the UI? I see I can have a ViewModel per View I am showing; the ViewLocator handles all the ViewModels (for caching as I understand). But what is driving the UI? If I have a Command defined in my ViewModel that says "ShowDetail"; do I have to write the code for displaying this View inside the ViewModel? Are there any examples of this? Thanks!

• How to read tags out of m4a files in .NET?

  - by dkackman

  I've got some heavily modified code that ultimately came from the Windows Media SDK that works great for reading tags out of MP3 and WMV files. Somewhere along the line, Windows Media Player added support for .m4a files (was it in Windows 7?) but the Windows Media API doesn't seem to reflect that addition (or at least IWMMetadataEditor2::OpenEx pukes on an .m4a file). What would be some good C# code or links on how to dig meta data tags out of m4a files? (Google has come up dry on the C# front.) UPDATE AtomicParsley did indeed end being the best approach. Since that code is a command line tool however I ended up having to create a managed wrapper around some of its functionality in order to use in-process. It is posted on google code if anyone else needs such a thing.

• Redirect output from sed 's/c/d/' myFile to myFile

  - by sixtyfootersdude

  I am using sed in a script to do a replace and I want to have the replaced file overwrite the file. Normally I think that you would use this: % sed -i 's/cat/dog/' manipulate sed: illegal option -- i However as you can see my sed does not have that command. I tried this: % sed 's/cat/dog/' manipulate > manipulate But this just turns manipulate into an empty file (makes sense). This works: % sed 's/cat/dog/' manipulate > tmp; mv tmp manipulate But I was wondering if there was a standard way to redirect output into the same file that input was taken from.

• Xcode 3.1.2 locks up when loading C++ project...?

  - by Stabledog

  I have a project which builds correctly from the command line. On one of my Macs (10.5) running Xcode 3.1.2, I can load it and build it in the Xcode IDE. On my other Mac (same configuration of software), Xcode sometimes loads the project, but always locks up with a spinning beach ball at some point before the build is done. Sometimes this occurs as the project is loaded, sometimes late in the build. I've tried doing a 'clean' on the project, I've tried pulling in the source code fresh from source control. So far, no luck -- I have to kill Xcode and in effect, cannot develop on this particular Mac. I've uninstalled and reinstalled Xcode. Any clues?

• Android : How to Remove all capital letters from image filenames before importing into Eclipse

  - by Hubert

  As you know, you can't have capital letters in your image filenames that you use in your Android project (Ressource/Drawables folder). I've got hundreds of small images (GOOG.GIF as an exemple) that I need to import into my project (I usually do a simple drag and drop from a desktop folder into Eclipse). So here's the question : How do I quickly change all the filenames (replace all capital letters to lower case) before importing into my project ? So, GOOG.GIF becomes goog.gif AAPL.GIF becomes aapl.gif etc. Any quick command line solution or another tool to do just that ? Thanks.

• Practicing buffer overflow attack in Ubuntu

  - by wakandan

  I am trying to learn to use buffer overflow attack in Ubuntu. Unfortunately, I cannot turn off Address Space Layout Randomization (ASLR) feature in this OS, which is turned on by default. I have tried some work around found in some fedora books: echo "0" > /proc/sys/kernel/randomize_va_space but for some reason the protection's still there. Please give me some suggestions. Thanks. [edit]Actually the above command was not successful, it said "Permission Denied", even with sudo. How can I fix that? [adding] I kept on getting segmetation fault error when it shows an address in stack. Is it related to non-executable stack in ubuntu :(?

• Vim open file under cursor

  - by ereOn

  Hi, Let's say I have the following file tree: / include/ library/ a.hpp b.hpp src/ a.cpp b.cpp And the following /src/a.cpp file: #include "a.hpp" #include "b.hpp" I always open Vim at the root directory. So when I want to load a.hpp I do : :tabnew include/library/a.hpp or: :tabnew **/a.hpp I'd like to map <F4> to open the file under the cursor in a new tab, using a recursive search. I tried the following mapping command: :map <F4> :tabnew **/expand("<cfile>")<cr> But obviously, this can't work, as it tries to open the file "/expand(" instead. Any clue on how I could do that ? Thanks.

• How to regularly merge two git repositories, one with submodules into one without

  - by smoothify

  I maintain a Drupal project in a git repository containing submodules. This works well for me overall, and I like the submodule approach. However, I would like to move my site to a hosting provider that offers deployment via git push but doesn't work with submodules. I would like to keep my current repository intact, and then when I'm ready to deploy, I would like to merge the changes from my repository into the deployment repository, but any submodules need to be exported into the tree. So, it needs to be (semi) automated, so I can just run a command or two and initiate the merge, and then push to the server. Ideally it would keep track of individual commits, but I wouldn't mind if it squashed them into a single commit. How would be the most effective way to achieve this?

• Selenium: How to click an HTML button element?

  - by Andrew

  I have button on the page that being used as a link to another page. So when the user clicks the button they are redirected to the right page. I am using the Selenium extension for PHPUnit and I would like to test that the button is correctly redirecting the user. Here is the HTML that I am trying to test: <button onclick="window.location='/sponsor';" value="Continue" type="button" id="sponsorContinue" name="sponsorContinue">Continue</button> I have tried a lot of different approaches to click the button, but I can't seem to get any of them to work: $this->click("//button[@id='sponsorContinue']"); This command executes and does not throw any errors, but the page isn't redirected. It works fine when I manually click the button. What should I do?

• php search and replace

  - by Dave

  I am trying to create a database field merge into a document (rtf) using php i.e if I have a document that starts Dear Sir, Customer Name: [customer_name], Date of order: [order_date] After retrieving the appropriate database record I can use a simple search and replace to insert the database field into the right place. So far so good. I would however like to have a little more control over the data before it is replaced. For example I may wish to Title Case it, or convert a delimited string into a list with carriage returns. I would therefore like to be able to add extra formatting commands to the field to be replaced. e.g. Dear Sir, Customer Name: [customer_name, TC], Date of order: [order_date, Y/M/D] There may be more than one formatting command per field. Is there a way that I can now search for these strings? The format of the strings is not set in stone, so if I have to change the format then I can. Any suggestions appreciated.

• Massive git commit squashing

  - by Nycto

  My company is in the middle of converting from CVS over to git. We've been on CVS for a long time, so there is a huge history. Too much to do by hand. Looking at the logs, there is a lot of squashing that could be done. A whole lot. What I would like to do is hook in a script that will compare two adjacent commits. If it returns true, then concatenate the commit messages and squash the commits. I would also be happy with a command that accepts two commits and a commit message, then squashes them together. git rebase --interactive is close to what I need, but "squash" requires far too much manual intervention. I also looked at using "fixup" instead of squash, but I don't want to lose the commit messages. Any ideas?

• Python script run via cron does not execute occassionally

  - by gcorne

  I have a simple python script for fetching tweets and caching them to disk that is configured to run every two minutes via cron. */2 * * * * (date ; /usr/bin/python /path/get_tweets.py) >> /path/log/get_tweets.log 2>&1 The script runs successfully most of the time. However, every so often the script doesn't execute. In addition to other logging, I added a simple print statement above the meat of the script and nothing except the output from the initial date command makes it to the log. #!/usr/bin/python # Script for fetching tweets and then storing them as an HTML snippet for inclusion using SSI print "Starting get_tweets.py" Any ideas? The system is a VPS running Centos 5.3 with python 2.4.

• Ubuntu quickly (python/gtk) - how to monitor stdin?

  - by neil

  I'm starting to work with Ubuntu's "quickly" framework, which is python/gtk based. I want to write a gui wrapper for a textmode C state-machine that uses stdin/stdout. I'm new to gtk. I can see that the python print command will write to the terminal window, so I assume I could redirect that to my C program's stdin. But how can I get my quickly program to monitor stdin (i.e. watch for the C program's stdout responses)? I suppose I need some sort of polling loop, but I don't know if/where that is supported within the "quickly" framework. Or is redirection not the way to go - should I be looking at something like gobject.spawn_async?

  Hey all, If I have the following code: main(int argc, char *argv[]){ char serveradd[20]; strcpy(serveradd, argv[1]); int port = atoi(argv[2]); printf("%s %d \n", serveradd, port); The first two arguments to the command line are printed. However, if I do this: char serveradd[20]; strcpy(serveradd, argv[1]); int port = atoi(argv[2]); char versionnum[1]; strcpy(versionnum, argv[3]); printf("%s %d %s \n", serveradd, port, versionnum);` The first argument (serveradd) does not print out to the screen and is not being stored... Why is this happening and how can I fix it? Thanks!
