  • bash-completion for xelatex

    - by andreas-h
    I'm on Ubuntu 12.04. When using bash as my shell, I can just type latex my_do <TAB> to compile a file my_document.tex, as *bash_completion* does the auto-complete. However, this auto-completion does not work for the xelatex executable. So I would like to add the same auto-complete functionality for xelatex as exists for latex. I could find that the latex auto-complete feature comes from the file /etc/bash_completion, where I could find a line complete -f -X '!*.@(?(la)tex|texi|dtx|ins|ltx)' tex latex slitex jadetex pdfjadetex pdftex pdflatex texi2dvi Now I could of course just add xelatex to that line and everything is fine. However, I'm wondering if I could instead put a file in /etc/bash_completion.d, as this would leave the system file untouched. Unfortunately, I'm at a complete loss about the syntax -- but maybe someone can help me here?

  • Making a DVD video with a still image and PCM 16bit audio with ffmpeg

    - by João
    I'm trying to make a small video with a still image and a sound file playing in the background to pass it to dvdauthor and create a DVD. The command I'm using is this: ffmpeg -loop_input -i image.jpg -qscale 2 -i song.flac -aspect 4:3 -target pal-dvd -acodec pcm_s16le -shortest output.mpg However, the resulting video file doesn't have sound at all (testing it on VLC Player). I don't know if I can't combine "-acodec pcm_s16le" with "-target pal-dvd" to override the later, or if there is something else wrong with the command. If I try without the "-acodec pcm_s16le" parameter the video and audio works, I can even create a DVD ISO with it. However, the audio stays as AC3. I wanted to include with the video the lossless audio, not a compressed one. I suppose the DVD standart allows to have PCM audio in it, am I right?

  • MissingSourceFile when I run "cucumber features"

    - by Jess
    I had cucumber 0.6.1 working quite fine... but I ran the gem update cucumber command, and things went smoothly. Then when I decided to run the cucumber features command, I received this error: Using the default profile... no such file to load -- cucumber/webrat/element_locator (MissingSourceFile) /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in gem_original_require' /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:inpolyglot_original_require' So I tried a few things... I did a gem update on webrat, that didn't work. I removed all previous versions of cucumber by doing gem uninstall cucumber then selecting past versions. Same with webrat. No luck. What am I doing wrong?

  • how to write unicode hello world in C on windows

    - by hatchetman82
    im tyring to get this to work: #define UNICODE #define _UNICODE #include <wchar.h> int main() { wprintf(L"Hello World!\n"); wprintf(L"£?, ?, ?!\n"); return 0; } using visual studio 2008 express (on windows xp, if it matters). when i run this from the command prompt (started as cmd /u which is supposed to enable unicode ?) i get this: C:\dev\unicodevs\unicodevs\Debugunicodevs.exe Hello World! -ú8 C:\dev\unicodevs\unicodevs\Debug which i suppose was to be expected given that the terminal does not have the font to render those. but what gets me is that even if i try this: C:\dev\unicodevs\unicodevs\Debugcmd /u /c "unicodevs.exe output.txt" the file produced (even though its UTF-8 encoded) looks like: Hello World! £ì the source file itself is defined as unicode (encoded in UTF-8 without BOM). the compiler output when building: 1------ Rebuild All started: Project: unicodevs, Configuration: Debug Win32 ------ 1Deleting intermediate and output files for project 'unicodevs', configuration 'Debug|Win32' 1Compiling... 1main.c 1.\main.c(1) : warning C4005: 'UNICODE' : macro redefinition 1 command-line arguments : see previous definition of 'UNICODE' 1.\main.c(2) : warning C4005: '_UNICODE' : macro redefinition 1 command-line arguments : see previous definition of '_UNICODE' 1Note: including file: C:\Program Files\Microsoft Visual Studio 9.0\VC\include\wchar.h 1Note: including file: C:\Program Files\Microsoft Visual Studio 9.0\VC\include\crtdefs.h 1Note: including file: C:\Program Files\Microsoft Visual Studio 9.0\VC\include\sal.h 1C:\Program Files\Microsoft Visual Studio 9.0\VC\include\sal.h(108) : warning C4001: nonstandard extension 'single line comment' was used 1Note: including file: C:\Program Files\Microsoft Visual Studio 9.0\VC\include\crtassem.h 1Note: including file: C:\Program Files\Microsoft Visual Studio 9.0\VC\include\vadefs.h 1Note: including file: C:\Program Files\Microsoft Visual Studio 9.0\VC\include\swprintf.inl 1Note: including file: C:\Program Files\Microsoft Visual Studio 9.0\VC\include\wtime.inl 1Linking... 1Embedding manifest... 1Creating browse information file... 1Microsoft Browse Information Maintenance Utility Version 9.00.30729 1Copyright (C) Microsoft Corporation.

  • Check connection and reconnect wifi

    - by Ruud
    I'm building a wireless photoframe. The one thing I haven't been able to figure out is how to get my wifi connection back up using a recommended method. Right now I edited /etc/network/interfaces so wlan0 is started at boot: auto wlan0 iface wlan0 inet dhcp wireless-essid ourssid This method works fine for booting. But I found that if I do not check the connection for a long time (could be a week) it might be down. So I should reconnect. What I do now to verify the connection is working is downloading a file from the server that can't be cached (http://server.ext/ping.php?randomize=123456) If I fail to retrieve the file I assume that the connection is no longer working and I run a shell script like #!/bin/bash ifconfig wlan0 up iwconfig wlan0 essid "ourssid" dhclient wlan0 And the connection comes back. But I can't find anything if this is in any way a good method. Can this be improved upon, or is this already right?

  • C++ EZWindows Linker Errors when trying to run demos

    - by Brent Nash
    I'm attempting to download and use the EZWindows ( http://www.cs.virginia.edu/c++programdesign/software/ ) SPARC installation (the http://www.cs.virginia.edu/c++programdesign/software/EzWindows2a-SPARC.tar.gz file).

  • Problem with recording audio in Flash (Red5, ffmpeg)

    - by AT
    I'm trying to implement a small program with Flash and php that records audio and converts it to mp3. Currently I have Red5 server up and running, I can connect to it with no problems and I can publish flv recordings to the server. When I listen to the flv with Wimpy FLV player it seems to be fine. The problem comes when I'm trying to convert it with ffmpeg on the command line. I'm simply using a command ffmpeg -i but the output wav is about 50% slower than the input. When I record 10sec, the output is 15sec and pitched down. I've also tried all kinds of bitrate settings, -nv option, etc. but nothing seems to work. I have a recent version of ffmpeg that supports nellymoser format.. Don't know what to do. Anyone have any ideas?

  • How can I view multiple git diffs side by side in vim

    - by Pete Hodgson
    I'd like to be able to run a command that opens up a git diff in vim, with a tab for each file in the diff set. So if for example I've changed files foo.txt and bar.txt in my working tree and I ran the command I would see vim open with two tabs. The first tab would contain a side-by-side diff between foo.txt in my working tree and foo.txt in the repository, and the second tab would contain a side-by-side diff for bar.txt. Anyone got any ideas?

  • Remapping Shift Selection in Gnome Terminal

    - by Gowie47
    Hey so I was hoping somebody could help me out in finding a way to get shift-selection working in gnome-terminal on Ubuntu 11.10. I found the question/bug report below but neither seem to have a solution. I use Emacs for development and being able to select my current line with shift-ctrl-a/e is something I find myself trying to do every couple of minutes. I use 10.04 at work and this is possible so I am not sure what has changed. If it matters I am using Gnome 3 Shell and I use bashish to style my terminal. Thanks in advance! https://bugs.launchpad.net/ubuntu/+source/vte/+bug/546021 http://askubuntu.com/questions/31991/using-the-shift-key-in-terminal

  • WPF Standard Commands - Where's Exit?

    - by Andrew Shepherd
    I'm creating a standard menu in my WPF application. I know that I can create custom commands, but I know there are also a bunch of standard commands to bind to. For example, to open a file I should bind to ApplicationCommands.Open, to close a file I should bind to ApplicationCommands.Close. There's also a large number of EditCommands, ComponentCommands or NavigationCommands. There doesn't seem to be an "Exit" command. I would have expected there to be ApplicationCommands.Exit. What should I bind to the "Exit" menu item? To create a custom command for something this generic just seems wrong.

  • RCP applicatoon activities

    - by Peter
    I have a problem with my RCP application. First, I defined an activity in my plugin.xml: <extension point="org.eclipse.ui.activities"> <activity id="myproject.view.input.activity" name="myproject.view.input.activity"> <enabledWhen> <with variable="myproject.view.input.active"> <equals value="ENABLED"> </equals> </with> </enabledWhen> </activity> <activityPatternBinding activityId="myproject.view.input.activity" pattern="myproject.gui/myproject.view.input"> </activityPatternBinding> Then i defined my SourceProvider: <extension point="org.eclipse.ui.services"> <sourceProvider provider="myproject.util.CommandState"> <variable name="myproject.view.input.active" priorityLevel="workbench"> </variable> And, finally, my CommandState class: public class CommandState extends AbstractSourceProvider { public final static String OUTPUT_VIEW = "myproject.view.input.active"; // then goes some others variables, i just skip them // .... public final static String [] ACTIONS = {OUTPUT_VIEW /*and all others variables*/}; public final static String ENABLED = "ENABLED"; public final static String DISENABLED = "DISENABLED"; private final Map <String, String> currentState = new HashMap <String, String> (); @Override public void dispose() { } @Override public String[] getProvidedSourceNames() { return ACTIONS; } @Override public Map <String, String> getCurrentState() { return currentState; } public void setEnabled(boolean enabled, String [] commands) { String value = enabled ?

For commands it works fine, they are enabling or disabling correctly. But when i try to disable view and open perspective, that contains that view (myproject.view.input), it opened without that view, but also throws exception: !STACK 1 org.eclipse.ui.PartInitException: Could not create view: myproject.view.input at org.eclipse.ui.internal.ViewFactory.createView(ViewFactory.java:158) I can show full stacktrace if anyone want. I tried to debug my application and before i open my perspective whith that view, i checked currentState of my CommandState source provider, and all seemes to be ok: all variables values are correct and myproject.view.input.active = DISABLED Can anyone say, why exception is thrown? Thanks for any help. Sorry for big post and bad language

  • ADO.NET Commands and SQL query plans

    - by ingredient_15939
    I've been reading up on query plans and how to minimise duplicate plans being created by SQL Server for the same basic query. For example, if I understand correctly, sending both these query strings will result in 2 different query plans: "SELECT FirstName FROM Members WHERE LastName = 'Lee'" "SELECT FirstName FROM Members WHERE LastName = 'MacGhilleseatheanaich'" Using a stored procedure avoids this, as the query plan is the same, and "LastName" is passed as a variable, eg: CREATE PROCEDURE sp_myStoredProcedure @LastName varchar(100) AS SELECT FirstName FROM Members WHERE LastName = @LastName Go Now, my question is whether the same applies to the Command object (eg. SQLClient.SQLCommand in ADO.NET). The reason I ask is that string parameters don't have a defined max length, as in the code above. Take the following code: MyCmd.CommandText = "SELECT FirstName FROM Members WHERE LastName = @LastName" MyCmd.Parameters.AddWithValue("@LastName", "Lee") Then later: MyCmd.Parameters.Clear() MyCmd.Parameters.AddWithValue("@LastName", "MacGhilleseatheanaich") Since @LastName hasn't been declared to SQL Server as having a defined maximum length, will SQL Server create a new query plan for every different value when I execute the command this way?

  • Deploying a Rails App to Multiple Servers using Capistrano - Best Practices

    - by Louise
    I have a rails application that I need to deploy to 3 servers - machine1.com, machine2.com and machine3.com. I want to be able to deploy it to all machines at once and each machine individually. Can someone help me out with a skeleton Capistrano config file / recipe? Should it all be in deploy.rb or should I break it out in machine1.rb, etc? I thought I was on the right track getting Capistrano to take in command line arguments, but it choked when I tried set the roles within the namespaces. I'd pass in 'hosts=1,2,3' as an argument and set the role:app/web/db to "machine#{host}.com" after splitting on the command and going into an each do |host| {}... Anyway, other than creating 4 different deploy.rb files and renaming it before running cap:deploy each time, I'm stumped. I'd like to be able to do the following: cap deploy:machine1:latest_version_from_svn cap deploy:all_machines:latest:version_from_svn Just don't know if it should all be in deploy.rb split up with namespaces or if it should be broken into multiple deploy*.rb files.

  • Executing multiple commands from a Windows cmd script

    - by Darren Greaves
    I'm trying to write a Windows cmd script to perform several tasks in series. However, it always stops after the first command in the script. The command it stops after is a maven build (not sure if that's relevant). How do I make it carry on and run each task in turn please? Installing any software or configuring the registry etc is completely out of the question - it has to work on a vanilla Windows XP installation I'm afraid. Ideally I'd like the script to abort if any of the commands failed, but that's a "nice to have", not essential. Thanks.

  • Can I use an opened gzip file with Popen in Python?

    - by eric.frederich
    I have a little command line tool that reads from stdin. On the command line I would run either... ./foo < bar or ... cat bar | ./foo With a gziped file I can run zcat bar.gz | ./foo in Python I can do ... Popen(["./foo", ], stdin=open('bar'), stdout=PIPE, stderr=PIPE) but I can't do import gzip Popen(["./foo", ], stdin=gzip.open('bar'), stdout=PIPE, stderr=PIPE) I wind up having to run p0 = Popen(["zcat", "bar"], stdout=PIPE, stderr=PIPE) Popen(["./foo", ], stdin=p0.stdout, stdout=PIPE, stderr=PIPE) Am I doing something wrong? Why can't I use gzip.open('bar') as an stdin arg to Popen?

  • Installing Microsoft VX1000 webcam

    - by KRistian
    I found a tutorial with people saying it works; here are the instructions I followed. I opened a shell as root on my system and launched the following: wget http://linuxtv.org/hg/v4l-dvb/archive/tip.tar.gz tar zxvf tip.tar.gz cd v4l... (whatever the newly created directory name is) make all sudo make install Then I edited /etc/modprobe.d/blacklist-custom and added blacklist sn9c102. After reboot, I launched sudo gstreamer-properties. However when I type tar zxvf tip.tar.gz it displays: tar: You may not specify more than one `-Acdtrux' or `--test-label' option Try `tar --help' or `tar --usage' for more information. Why? How can I do this? Thanks in advance.

  • Is there a way to convert a swf to an .abc file?

    - by Jeremy Ruppel
    I'm looking for a way, preferably a command-line utility, to pump out an .abc file for a compiled swf. I've looked into asc.jar, but so far it seems like it can only accept classes, not compiled swfs. Anybody know of a good way to do this? The end-goal of this process is to use Zwetan's RedTamarin project to run describeType on some specific classes inside a loaded swf, but there are complications with SecurityDomain preventing me from using Loader.loadBytes. If there's another good way to describe classes in the loaded swf via command-line, I'd be interested in that solution as well. Cheers, J

  • How to write a virtual conditional breakpoint in java

    - by Phuong Nguyen de ManCity fan
    I'm sorry if the question title may mis-inform you, but I cannot find a proper word to explain that. If you ever working with .NET, you would know that there is Assert class that will automatically wake up and attach debugger if necessary and then have debugger (Visual Studio) pausing at the Assert command, given the Assert command failed. Given I'm running a java program and having debugger connected, then how can I have debugger to break on certain condition without manually setup a break point? I'm expecting something like that: void doSomeThing(String x){ if (x==null) breakDebuggerNow(); }

  • FFmpeg on iPhone

    - by gn-mithun
    Hello, I have downloaded ffmpeg libraries for iPhone and compiled them. My objective is to create a movie file from a series of images using ffmpeg libraries.The amount of documentation for ffmpeg on iphone is very less. I checked an app called iFrameExtractor, which does the opposite of what i want, it extracts frames from a video. On the command line there is a command called ffmpeg -f image2 -i image%d.jpg video.mov This turns a series of images into a video. I actually checked it on my mac and it works fine. What i wanted to know was how do we get the equivalent in iPhone. Or rather which class/api or method to call. There are a couple of examples of apps doing this on iPhone. Not sure whether they do it through ffmpeg though. Anyways, for reference "Time lapser" and "reel moments" Thanks in advance

  • ApplicationCommand.Paste happens twice

    - by Carlo
    Hi, well this is driving me crazy. We have a command like so: <CommandBinding Command="ApplicationCommands.Paste" CanExecute="HasClipboardData" Executed="OnPasteExecuted"/> And the code for OnPasteExecuted is this: private void OnPasteExecuted(object sender, ExecutedRoutedEventArgs e) { CurrentView.Paste(); e.Handled = true; } That code gets executed twice, and I have no idea why, we also have the other commands: Cut, Copy, Undo, Redo, those work just fine, the problem is only with Paste. Let me know if you have any idea of what could be going on. Thanks!

  • Polygon with different line width (in R)

    - by Tal Galili
    Hi all, I would like to use a command like this: plot(c(1,8), 1:2, type="n") polygon(1:7, c(2,1,2,NA,2,1,2), col=c("red", "blue"), # border=c("green", "yellow"), border=c(1,10), lwd=c(1:10)) To create two triangles, with different line widths. But the polygon command doesn't seem to recycle the "lwd" parameter as it does the col or the border parameters. I would like the resulting plot to look like what the following code will produce: plot(c(1,8), 1:2, type="n") polygon(1:3, c(2,1,2), col=c("red"), # border=c("green", "yellow"), border=c(1,10), lwd=c(1)) polygon(5:7, c(2,1,2), col=c( "blue"), # border=c("green", "yellow"), border=c(1,10), lwd=c(10)) So my questions are: Is there something like polygon that does what I asked for? (If not, I would do it by creating a new polygon function that will break the original x,y by their NA's, although I am not yet sure what is the smartest way to do that...) Thanks, Tal
