• JavaScript: What is AJAX? What is jQuery?

  - by dcolumbus

  What exactly IS AJAX? Is there an official release? What exactly is jQuery? Is there an official release? From what I understand, these two "extensions" of JavaScript are just small scripts that enable extended functionality. But, what exactly are there? I mean, Adobe is a company that created Flash. If you want information about Flash, the official source is at Adobe. Is there an equivalent for AJAX and jQuery? I don't want to learn AJAX or jQuery form some shmo that doesn't know that correct syntax. I want to learn proper syntax and best practices.

• Mutt and msmtp interoperability

  - by illusionoflife

  I am working on configuring /mutt/ to send mail via /msmtp/. Strangely, if I user /msmtp/ from shell, all okay, that means, that .msmtprc is correct. However, mail sent with mutt do not come. I have this line in .muttrc. set sendmail="msmtp" How can I debug this problem? EDIT: I found, that if I send just text, like msmtp 'my-email' <<< "Hello", it works. But if I send fully builded email-header, it do not. Is it gmail politics or what?

• Perl SDL Windows Installation

  - by Blaise Roth

  I'm using Windows and I need the SDL Library to start using SDL with Perl. I've been pointed to http://www.libsdl.org/ to download it. My first queston is, which library do I want from that page? There's 3 to choose from... Then I've been pointed to 4 other SDL extensions by this page: http://arstechnica.com/gaming/news/2006/02/games-perl.ars. From those I've found there's a normal Win32 version and also a devel one. Which do I want? Thanks.

• Cygwin/Git Bizarre Terminal Issue

  - by emptyset

  Alright, this is weird. First off, this is mintty running on up-to-date cygwin, with git pulled from cygwin's setup.exe. I am running zsh. $ git clone https://<user>@<domain>/<repository>/ ~/src/project/dev Initialized empty Git repository in /cygdrive/c/src/project/dev/.git/ Password: <actual password in plain text appears> # Nothing happens... ^C $ <password text that I just typed> zsh: command not found: <same password text> What is going on here? Is this a terminal problem, a shell problem, a git problem, or a cygwin problem? Update: Yes, I'm running the Cygwin git version, not the Windows version: $ which git /usr/bin/git $ git --version git version 1.7.1 $ /cygdrive/c/Program\ Files\ \(x86\)/Git/bin/git.exe --version git version 1.7.0.2.msysgit.0

• svn diff including annotate/blame-alike information of when changes where made by who

  - by Wouter Coekaerts

  Can you add annotate/blame-alike information to svn diff, so that for every changed line it includes which user and revision changed that line? For example, an annotate-diff comparing revisions 8-10 could output something like: 9 user1 - some line that user1 deleted in revision 9 10 user2 + some line that user2 added in revision 10 The context, lines around it which haven't changed, may be included as well or not, doesn't matter. It's not just a matter of "quickly" writing a shell script combining the output of svn diff and svn annotate. annotate for example will never show you who removed a line. It's also not a matter of doing annotate on a revision in the past: We're not interested in who originally added the line that got removed (that's not the one who "caused" the diff), we want to know who removed it. I suspect the only way to implement something to do this is to inspect each and every commit between the two revisions being compared (and somehow map all the changes in the separate diffs to lines in the total diff)... Does there exist a tool that does something like that?

• Renaming and Moving Files in Bash or Perl

  - by Katie

  HI, I'm completely new to Bash and StackOverflow. I need to move a set of files (all contained in the same folder) to a target folder where files with the same name could already exist. In case a specific file exists, I need to rename the file before moving it, by appending for example an incremental integer to the file name. The extensions should be preserved (in other words, that appended incremental integer should go before the extension). The file names could contain dots in the middle. Originally, I was thinking about comparing the two folders to have a list of the existing files (I did this with "comm"), but then I got a bit stuck. I think I'm just trying to do things in the most complicated possible way. Any hint to do this in the "bash way"? It's OK if it is done in a script other than bash script.

• Understanding the Linux boot process, subsystem initialization, & udev rules?

  - by quack quixote

  I'm creating UDEV rules for automounting external drives on a headless server, much in the same way as Gnome-VFS does automounting during a user session. I'm concerned with the rule's behavior at boot-time. There's a good chance one of these drives will be connected during a boot, and I'd prefer any connected drives get mounted in the right place. The drives might be either USB or Firewire, and they are mounted from a shell script fired off by UDEV on detecting an "add". Here are my questions: When UDEV runs the mount for these devices at boot, will the system be ready to mount it? Or will the script get triggered too early? If it's too early, what's a good way for a script to tell that the system isn't ready yet (so sleep a while before checking again)? The UDEV rule matches ACTION=="add". Does this event even fire at system boot?

• Rails - Associations - Automatically setting an association_id for a model which has 2 belongs_to

  - by adam

  I have 3 models class User < ... belongs_to :language has_many :posts end class Post < ... belongs_to :user belongs_to :language end class Language < ... has_many :users has_many :posts end Im going to be creating lots of posts via users and at the same time I have to also specify the language the post was written in, which is always the language associatd with the user i.e. @user.posts.create(:text => "blah", :language_id => @user.language_id) That's fine but the way I set the language doesn't sit well with me. The language will always be that of the users so is there a 'best-practice' way of doing this? I know a little about callbacks and association extensions but not sure of any pitfalls.

• Can I ask Postgresql to ignore errors within a transaction

  - by fmark

  I use Postgresql with the PostGIS extensions for ad-hoc spatial analysis. I generally construct and issue SQL queries by hand from within psql. I always wrap an analysis session within a transaction, so if I issue a destructive query I can roll it back. However, when I issue a query that contains an error, it cancels the transaction. Any further queries elicit the following warning: ERROR: current transaction is aborted, commands ignored until end of transaction block Is there a way I can turn this behaviour off? It is tiresome to rollback the transaction and rerun previous queries every time I make a typo.

• Load Balancer recommendations

  - by delerious010

  I provide hosting service for about 250 clients to date, and this is increasing on a monthly basis. For each client, I have 2 "services" configured for L4 balancing / persistence .. one on port 80, another for port 443 which redirects to another internal port as well as 4 servers per service. This equates to a total of 500 "services" and 2000 "servers". I'm currently running with a couple CoyotePoint load balancers, and have had a look at some Barracudas but so far I'm really not impressed by those. Could anyone recommend some good load balancers which would be able to support this sort of load ? And which offer a good API, or shell access to automate management.

• Installing PHP-GTK with PHP 5.3 on OS X

  - by Shabbyrobe

  I'm having trouble getting php-gtk installed with php 5.3 on os x. I'm currently using macports to do it and when I try to install php-gtk, it spews 'duplicate static' errors: Error: Target org.macports.build returned: shell command " cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_php_php5-gtk/work/php-gtk-2.0.1" && /usr/bin/make -j2 all " returned error 2 Command output: ext/gtk+/gen_pango.c:2951: error: duplicate 'static' ext/gtk+/gen_pango.c:2957: error: duplicate 'static' ext/gtk+/gen_pango.c:3097: error: duplicate 'static' ext/gtk+/gen_pango.c:3103: error: duplicate 'static' Is there a way to coerce it into building, or an alternative way to install it?

• Bitbanging a PIO on Coldfire/ucLinux

  - by G Forty

  Here's the problem: I need to program some hardware via 2 pins of the PIO (1 clock, 1 data). Timing constraints are tight - 10ms clock cycle time. All this, of course, whilst I maintain very high level services (CAN bus, TCP/IP). The downstream unit also ACKS by asserting a PIO pin, configured as an input, high. So this loop has to both read and write. I need to send 16 bits in the serial stream. Is there an established way to do this sort of thing or should I simply get the hardware guys to add a PIC or somesuch. I'd much prefer to avoid exotics like RTAI extensions at this stage. I did once see a reference to user-mode IO which implied a possible interrupt driven driver but lost track of it. Any pointers welcomed.

• SVN: Error validating server certificate for svn hook linux

  - by Dr Casper Black

  Hi, I managed to setup a SVN (over SSL) server and TortoiseSVN client on Win. I made a Post-Commit Hook for test project. The Post-Commit will update the web dir so the App in PHP can be executed with the newest version. It all works when done over shell. The only problem is, when i commit the changes over the client in Win the change is commited but HOOK throws error post-commit hook failed (exit code 1) with output: Error validating server certificate for 'https://SERVER_IP:443': - The certificate is not issued by a trusted authority. Use the fingerprint to validate the certificate manually! - The certificate hostname does not match. Certificate information: - Hostname: DEVSRVR - Valid: from Fri, 28 Jan 2011 09:22:45 GMT until Sat, 28 Jan 2012 09:22:45 GMT - Issuer: PHP, SS, SS, SRB - Fingerprint: 5f:d0:50:d6:dd:a6:d4:64:a5:ac:3a:4b:7c:7d:33:e3:75:dd:23:9f (R)eject, accept (t)emporarily or accept (p)ermanently? svn: OPTIONS of 'https://SERVER_IP/svn/myproject/trunk': Server certificate verification failed: certificate issued for a different hostname, issuer is not trusted (https://SERVER_IP)

• Sane(r) way to get character-encoding of CLI?

  - by danyowdee

  Hi all! I was writing a CLI-Tool for Mac OS X (10.5+) that has to deal with command-line arguments which are very likely to contain non-ASCII characters. For further processing, I convert these arguments using +[NSString stringWithCString:encoding:]. My problem is, that I couldn't find good information on how to determine the character-encoding used by the shell in which said cli-tool is running in. What I came up with as a solution is the following: NSDictionary *environment = [[NSProcessInfo processInfo] environment]; NSString *ianaName = [[environment objectForKey:@"LANG"] pathExtension]; NSStringEncoding encoding = CFStringConvertEncodingToNSStringEncoding( CFStringConvertIANACharSetNameToEncoding( (CFStringRef)ianaName ) ); NSString *someArgument = [NSString stringWithCString:argv[someIndex] encoding:encoding]; I find that a little crude, however -- which makes me think that I missed out something obvious...but what? Is there a saner/cleaner way of achieving essentially the same? Thanks in advance D

• How can I allow a linux subversion user to only execute svnserve?

  - by sbleon

  I've got a user that I'd like to only be able to use subversion. We like to use svn+ssh:// URLs sometimes (for public keys and whatnot), so I need them to be able to connect over ssh and run only the svnserve command. When using a svn+ssh URL, svn ssh'es in and passes the arguments "-c svnserve -t". I wrote a custom shell as follows to filter the commands that can be run. This works, but it's not passing the input to svnserve, so when I try to "svn up" I get "svn: Connection closed unexpectedly". #!/bin/bash if [ "$1" == "-c" ] && [ "$2" == "svnserve" ] && [ "$3" == "-t" ] && [ "$4" == ""] ; then exec svnserve -t else echo "Access denied. User may only run svnserve." fi

• Using physical disk with VMware Workstation

  - by chx

  I am using VMware Workstation 9.0 under Windows 7 and trying to load my Linux from Physicaldisk0. And it boots, grub sees the two partitions on the disk (I checked in command line) and the kernel and the initrd loads and then it stops saying "device not found"and drops me into an emergency shell. Indeed there is absolutely nothing in /dev not the /sda device it expects not /hda nothing that looks like a disk. Edit: I can boot the Linux disk just fine if I boot it from BIOS and not as a VM. Edit2: The question is, how can I make this setup work?

• IAR Embedded Workbench - setting endian-ness of variable

  - by Seidleroni

  I'm using IAR Embedded Workbench for ARM (ARM7TDMI-S) and the majority of my work is done using little-endian format. However, I saw in the manual that I can do something like : __big_endian int i, j; to declare those two variables as big endian (while the rest of the app as little endian). This seems like a fantastic feature, but when I try to compile, I always get the errror: Error[Pa002]: the type attribute "__big_endian" is not allowed on this declaration. The big endian line above is copied directly from the manual, but it does not work. This is a great feature of the compiler and would make life a big easier. Any ideas how to get it working? I have my language conformance set to 'Allow IAR extensions' on the C/C++ Compiler options tab on the IDE options.

• How can I get vim to set an ACL on its swap files?

  - by thsutton

  I use vim on an OS X Snow Leopard Server machine. A number of the directories I work in have ACLs (so that various groups of users can access them over AFP) that are inherited. For some reason, when I'm working in one of these directories, vim cannot read it's own swap files. It can create them fine but can't read them which, for some reason, makes it display the "swap file already exists" message (and no, the swap file does not already exist). vim -r lists the newly created swap file as "[cannot be read]". The owner and group are correct and the permissions are 0600, and the ACLs on the swap file and the file I'm editing are identical (as disclosed by ls -le and compared with diff). groups returns the same thing whether invoked from my login shell or via :! in vim. Has anyone encountered (and hopefully resolved) a problem like this before?

• How do I give MacPorts privileges?

  - by cojadate

  I tried to install PostgreSQL server development libraries using MacPorts and got the following: Warning: MacPorts running without privileges. You may be unable to complete certain actions (e.g. install). ---> Computing dependencies for postgresql-server-devel ---> Dependencies to be installed: postgresql-devel ---> Building postgresql-devel Error: Target org.macports.build returned: shell command failed Error: The following dependencies failed to build: postgresql-devel Error: Status 1 encountered during processing. To report a bug, see <http://guide.macports.org/#project.tickets> So I guess that means I need to running MacPorts with privileges and try again. Unfortunately I've no idea how to give MacPorts privileges. I'm running OS X 10.6.3

• Adding a trigger command to autocomplete function in zsh

  - by mkaito

  When you define an alias like alias g=git, the shell will pick it up and run the corresponding autocomplete function. Now, there's a program out there called hub, which is basically a supserset of git, with some added, github-specific functionality. The recommended way to use hub is to alias git=hub. Of course, this won't trigger the autocomplete function for git, which makes sense. Now, if I wanted to have git's autocomplete trigger for hub, the only way I know of is editing /usr/share/zsh/functions/Completion/Unix/_git and adding hub in the first line as trigger. While this works, it isn't practical, since this file will get overwritten with the next zsh release. Assuming hub won't provide a zsh completion function any time soon, is there another way of adding hub to the trigger commands for git's autocomplete function?

• username and password for rsync in script

  - by sims

  I'm creating a cron job to keep two dirs in sync. I'm using rsync. I'm running an rsync daemon. I read the manual and it says: RSYNC_PASSWORD Setting RSYNC_PASSWORD to the required password allows you to run authenticated rsync connections to an rsync daemon without user intervention. Note that this does not supply a password to a shell transport such as ssh. USER or LOGNAME The USER or LOGNAME environment variables are used to determine the default username sent to an rsync daemon. If neither is set, the username defaults to 'nobody' I have something like: #!/bin/bash USER=name RSYNC_PASSWORD=pass DEST="server::module" /usr/bin/rsync -rltvvv . $DEST I also tried exporting (dangerous, I know) USER and RSYNC_PASSWORD. I also tried with LOGNAME. Nothing works. Am I doing this correctly?

• How to create a VS2010 extension that uses Language Services

  - by Hades32

  Creating extensions got much easier with Vs2010, but this seems not to be the case for everything... My aim: I wnat to make method calls and property uses of STATIC classes ITALIC. (Just like Eclipse and Java) I think I need to talk to the C# Language Service for this information, but searching for "Language Service" just yields results on how to CREATE one, not how to use one of the existing ones... To get this question a little more general: How do I get information about properties of the code (static/visibility etc) for using it in a VSX?
