• Ubuntu Chromium bookmark icons blank

  - by Matt Parkins

  Ever so often I load Chromium and it refuses to load my profile. Now that doesn't happen any more but since then it refuses to load the icons for my bookmarks which, if you look at the attached pic, is my only way of identifying which icons do what (other than hover for tool-tip, or actually pressing the icon button). The other possible variable is that the bookmarks are meant to sync with Google sync - I'm not sure if that is a factor. How do I restore the icons to my bookmark bar? Chromium version: Version 20.0.1132.47 Ubuntu 12.04 (144678)

• wildcard in httpd conf file?

  - by Joe

  Here is an example httpd config I'm currently using: <VirtualHost 123.123.123.123:80> ServerName mysite.com ServerAlias www.mysite.com DocumentRoot /home/folder </VirtualHost> I'm wondering, is it possible to have a wildcard for the ServerName & ServerAlias variable? Reason for asking is I have some software that is shared among multiple URL's all controlled in a CMS and it's kind of a pain to add new domains via ssh everytimee. And before someone points out a security hole, the software does check the current URL before doing any webpages :)

• free Raw-File Converter/Editor

  - by RCIX

  I have RAW files output by a program with a specific set of properties (Photoshop RAW, 16 bits, IBM PC byte order, no header, 1 non-interleaved channel, variable sizes like 257X257 or 129X513); does anyone know of a free tool that will allow me to convert to and from this format, and possibly do basic editing (selection, copy/paste, rotation of selection)? I've tried Picasa, XNView, and Paint Shop Pro 7 and none of them work properly. The closest i get is Paint Shop Pro which will at least make a serviceable attempt to open these files but i can't set all of the proper settings. XNView just might be able to edit it if i can figure out how to change the open settings for a particular raw file. So my questions at current are: how do i tell XNView to open a raw file a particular way? Failing that, is there any free tool that can open Photoshop-RAW files with the above settings (that's not photoshop)? If it helps, i'm trying to import/export/edit hieghtmap data for maps for Supreme Commander.

• /proc/pid/environ missing variables

  - by Josh Arenberg

  google is giving no love on this one today, so I turn to the experts... I'm currently hacking together a script that relies on the /proc/pid/environ feature in Linux (RHEL 4) to check for a particular environment variable. Trouble is, it seems certain environment variables aren't showing up in there for some reason. Example: create some test vars: $ export T_1=testval TEST_1=testval T=testval TESTING_LONGEST=testval open a subshell: $bash $ cat /proc/self/environ|tr "\0" "\n"|grep testval TESTVARIABLE_LONGEST=testval T=testval hmm... where did T_1 and TEST_1 go?? what rules govern this strange universe? Thanks in advance, Josh

• Proper way to rotate Nginx logs

  - by depesz

  I would like to achieve rotation of nginx logs that: would work without any extra software (i.e. - best if without "logrotate") would create rotated files with names based on date Best approach is something like PostgreSQL has - i.e. in it's log_filename config variable I can specify strftime-style %Y-%m-%d, and it will automatically change log on date (or time) change. Another approach from apache - sending logs via pipe to rotatelogs program. As far as I was able to search - no such approach exists. All I can do, is to use logrotate with dateext option, but it has it's own set of drawbacks, and I'd rather use something that works like |rotatelogs or log_filename in PostgreSQL.

• Equivalent of PHP setlocale in an APACHE config file

  - by Nicolas

  I need to display a date in french locale. A solution is to use setlocale(LC_TIME, 'fr_FR'); But I'm looking to set the locale directly in the configuration of my apache server. In the /etc/httpd/conf/httpd.conf file, I tried <VirtualHost *:80> ... SetEnv LC_TIME 'fr_FR' </VirtualHost> without any effect. In which php or apache configuration file should I define the LC_TIME variable?

• This weird behaviour from cronjob

  - by The DOCTOR from TARDIS

  I have set the crontab like this: */5 0 * * * /www/permitChat.sh and the /www/permitChat.sh is this: # We are setting the name of file # in the variable along with complete path. sFilePath=`date +\/www\/ChatLogs\/%Y\/%m/%d_%m_%Y.txt` # First we set its permissions to # readable by all users, and then # modify them to be writable by only root. chmod a=r $sFilePath chmod u+w $sFilePath ls -lh $sFilePath The trouble I am facing is, the cron gets executed after 12:00 PM everyday, instead of executing at 12:00 AM to 01:00 AM, every 5 minutes. What could be wrong? All my system variables appear to be synced.

• Can't use command line – "command not found" after editing PATH

  - by MEM

  I'm running OS X Mavericks and was trying to install MAMP PRO 2.2. I was trying to configure the PATH variable to have the PHP binaries of MAMP PRO. I added the following line on my ~/.bash_profile file: export PATH=/Applications/MAMP PRO/bin/php/php5.5.3/bin:$PATH As you may notice, since I have MAMP PRO and not just MAMP, I've added a space. As a consequence, I know have the following error each time I run the terminal: -bash: export: `PRO/bin/php/php5.5.3/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin': not a valid identifier Worst: I can't get any command to run, like: ls, clear etc. I always get: "command not found" I don't even know the absolute path for ls. How can I make the commands work again, so that I can properly fix the path I was trying to setup on the .bash_profile file?

• CDPATH in windows command prompt?

  - by barlop

  The accepted answer of this question Fast Ways of Cd'ing on *nix? mentions bash having CDPATH is there an equivalent in windows? so from any directory e.g. c:\windows I could do c:\windowscd compbar* and it'd take me to m:\a\b\c\d\e\compbar what if there are many compbar directories? well, the CDPATH solution is one solution, I suppose you order them it'd search through the CDPATH environment variable and choose the first. I'd like that for windows.

• X11 forwarding from one server to other

  - by n3oblit7

  I have a setup where I need to forward X11 from my local machine (laptop) to a Virtual machine. The server hosting this VM cannot be reached directly from my laptop. I need to first login to a gateway and from this gateway, I can access the VM. How can I forward X11 from my laptop to this VM? I have tried following but these do not work: [laptop # ] ssh -X [gateway] [gateway # ] ssh -X [VM] [laptop # ] ssh -tX [gateway] ssh -X [VM] I could forward X11 only till the gateway. (DISPLAY variable gets set on gateway)

• How can I get Visual Studio 2008 to align my assignment operators?

  - by Alison R.

  I had this in Vim and miss it dearly now that I'm confined to Visual Studio. I'd like to take this: MyType type_obj = new MyType(); MyLongerType longer_type_obj = new LongerType() To this: MyType type_obj = new MyType(); LongerType longer_type_obj = new LongerType() I have found some macros for this on the web, but they seem to be for an older version of Visual Studio (< 2008). Here is one from 2000. Edit: Further digging in Google turned up this one: http://www.omegacoder.com/?p=8 It seems to work to align equals signs, but I haven't yet figured out if it can align the local variable names, too. Still no clue as to whether I could just get it to perform this sort of behavior with a Ctrl E+D, although that might not be practical considering how it works. (It aligns going down from the line which currently has focus.)

• vim: highlighting a search term without moving the cursor

  - by ajwood

  Using Vim, I sometimes find myself staring at a section of source code for a while and suddenly want some variable on the screen to pop out. That's easy: /<var> which highlights them all. My issue is that it more often than not the search shifts my window so I'm not looking at the source code from the same place. Even if it's only shifted a few lines, it's still throws me off since I need to take a few seconds to figure out where things have moved to. Is it possible to highlight a search term without moving the cursor to the next match?

• REMOTE_USER through Apache reverse proxy

  - by Laurent

  I have an Apache webserver with mod_proxy enabled and a Virtualhost, proxy.domain.com. This proxy is configured to prompt the user for credentials with AuthType Basic. Then, the content of web.domain.com is available through the proxy with ProxyPass and ProxyReverse. However, the REMOTE_USER variable is empty. I read different things to achieve this with mod_rewrite and mod_headers but all my tries have failed. Does anybody has been luckier than me? Thanks.

• "ant" is not recognized as command in Windows

  - by user1294663

  This is my first time developing Android applications. I'm developing an Android app on Eclipse on Windows 7. I would like to run the Android app from the Windows 7 command line interface. I have my Android device connected to the PC. The workspace directory that I use to store the Android project is C:\Users\Guest\Desktop\Software Applications Development\Java\Android Moblie Applications Projects\Eclipse Indigo for Java EE x64-bit\project workspace I opened the command line interface and I changed the working directory to the Android workspace directory. cd C:\Users\Guest\Desktop\Software Applications Development\Java\Android Moblie Applications Projects\Eclipse Indigo for Java EE x64-bit\project workspace I included Android sdk platform tools directory into the PATH environment variable. c:\Users\admin\Android-sdks\platform-tools Then I entered this into the Windows 7 command line interface: ant debug I have this error message on the cmd: ant is not recognised as an internal or external command, operatable program or batch file. What is the solution to this problem?

• MySQL com_select?

  - by symcbean

  I'm looking to tune my query cache a bit. According to 7.6.3.4. Query Cache Status and Maintenance in the manual: The Com_select value is given by this formula: Qcache_inserts + Qcache_not_cached + queries with errors found during the column-privileges check However in 5.1.5. Server Status Variables it suggests that this is maintained by the DBMS. Having said that mysql> show status like 'Com_select%'; Always returns a value of 1 - and I'm pretty sure I've run more than one non-cached select query on my database since it started. It looks as if other people are similarly confused. Is this status variable redundant? Which bit of the manual is wrong? TIA

• Installing isolated instance of MySQL on Windows using silent install with .msi

  - by Abram

  I'm trying to write an installer for an internal application we wrote. After it installs our application it then installs MySQL using the .msi installer in silent mode. I specify the install dir and data dir to that of a directory within my application's install directory, such as: msiexec /i @@MYSQL_INSTALLER_FILE@@ /qn INSTALLDIR="@@INSTALL_DIR@@\MySQL\" DATADIR="@@INSTALL_DIR@@\MySQL\" USERNAME="@@DB_USER@@" PASSWORD="@@DB_PASS@@" (the @@variable@@'s are replace by my installer routine using InstallJammer) Once installed, I use mysqld.exe to install a windows service with a custom service name and defaults file like so: mysqld.exe --install CustomMySQL --defaults-file="@@INSTALL_DIR@@\MySQL\my.ini" This works fine as long as there is not already another instance of MySQL installed. If there is it silently fails to install MySQL. Running the msi installer manually (double-click) shows an error that a previous version is already installed and just aborts. Is there a way to automate installing MySQL as an isolated instance, regardless of whether another version/instance is already installed?

• %sessionname% returns incorrect session name

  - by Samuel Walker

  I have a virtualised Windows XP SP3 machine, which I am connecting to over Remote Desktop. One of my scripts needs to use the %sessionname% variable. However this returns incorrect information. C:\>%sessionname% constantly returns RDP-Tcp#5, instead of the value for the currently connected session (RDP-Tcp#35 or similar), as shown in Task Manager This causes my scripts to contain incorrect information. What can I do to resolve this? Edit Further Information: A restart appears to solve the problem for the first connection, but then subsequent connections have the numbers fall out of sync again.

• How to Detect that Current (Bash) Shell is a (Vi/Vim) Subshell?

  - by Jeet

  From inside Vi/Vim, I can type: :shell to drop into a shell. Is there any way to detect that I am in a Vi-spawned subshell? The environmental variable SHLVL is 2, but that does not tell me explicitly that I am in a Vi/Vim-spawned subshell. On OS X, the following variables are also set: MYVIMRC, VIMRUNTIME, VIM. How universal are these? Can I count on these being set in any system, if and only if I am in a Vi/Vim subshell? If not, is there any portable, robust and hopefully efficient way to tell that I am in a Vi/Vim subshell? Thanks.

• ssh into my mac from my ipod

  - by mechko

  Ok so this is what I got, but it don't look right... The set up is as follows: My Mac is on a wireless network, presumably behind a firewall over which I have no admin privileges. Further, said wireless network changes my internal IP randomly at random times, so I do not know what my ip is. Note that localhost is a variable ip I forward some port or the other to my dns: ssh -R 19999:localhost:22 sourceuser@remotehost connect to my remotehost from my machine: ssh sourceuser@remotehost and then connect to the port I forwarded: ssh localhost -p 19999 [solved] Second question, there are a bunch of ssh clients for the iphone. Which one should I use? EDIT: Since jailbreak is not illegal, simply frowned upon by the Corporation, I've decided to go with that. I have a nice shell with openssh and the works. Best of all, it's free and it does exactly what you expect.

• Create a web interface that starts VM's on the server side

  - by xdragonforce

  I am creating a service called TorCompute which allows for creating virtual Tor Hidden Service servers on my infrastructure (I say infrastructure, by that I mean just the 3x 32GB RAM machines waiting to be purchased). What I would like to be able to do is for users to log on, access the web interface and spin up a VM with a variable about of RAM/Disk Space. I've written the PHP for logging in and have a nice web interface, just I need the code to actually create them! How would I go about doing this? Thanks, Stewart EDIT: I will run them with VMWare Server, with vmrun

• MySQL slow query log logging all queries

  - by Blanka

  We have a MySQL 5.1.52 Percona Server 11.6 instance that suddenly started logging every single query to the slow query log. The long_query_time configuration is set to 1, yet, suddenly we're seeing every single query (e.g. just saw one that took 0.000563s!). As a result, our log files are growing at an insane pace. We just had to truncate a 180G slow query log file. I tried setting the long_query_time variable to a really large number to see if it stopped altogether (1000000), but same result. show global variables like 'general_log%'; +------------------+--------------------------+ | Variable_name | Value | +------------------+--------------------------+ | general_log | OFF | | general_log_file | /usr2/mysql/data/db4.log | +------------------+--------------------------+ 2 rows in set (0.00 sec) show global variables like 'slow_query_log%'; +---------------------------------------+-------------------------------+ | Variable_name | Value | +---------------------------------------+-------------------------------+ | slow_query_log | ON | | slow_query_log_file | /usr2/mysql/data/db4-slow.log | | slow_query_log_microseconds_timestamp | OFF | +---------------------------------------+-------------------------------+ 3 rows in set (0.00 sec) show global variables like 'long%'; +-----------------+----------+ | Variable_name | Value | +-----------------+----------+ | long_query_time | 1.000000 | +-----------------+----------+ 1 row in set (0.00 sec)

• What methods are there to configure puppet to serve resources for multiple environments?

  - by cclark

  I seem to come across two ways for using puppet in multiple environments: 1) Install a puppetmaster in each environment and only update the recipes from source control for that environment when ready to deploy the recipes in that environment. 2) Use one puppetmaster and use a variable in the puppet.conf of each client to specify the environment and then in the puppetmaster specify a different modulepath for each environment and each of those paths is updated to the branch of the recipe repository intended for that environment (e.g. dev, staging, production). Only running one puppetmaster seems like it is one less piece of infrastructure to keep running but there is some additional complexity in the configuration. Are there additional pros or cons to one of these methods or something which I'm missing entirely?

• Where to set java heap options (e.g. -Xmx) for Tomcat 6 under Ubuntu 9.04?

  - by Chris

  I'm running Tomcat using the tomcat6 package from Ubuntu 9.04, which makes a daemon out of Tomcat using jsvc. I'd like to know the proper way to set Java heap options like -Xmx for Tomcat. I'd like to put the configuration wherever is most stylistically correct, and wherever is least likely to be overwritten by Ubuntu package updates. The options I see right now: Hard-code them somewhere in /etc/init.d/tomcat6. Hard-code them somewhere in /usr/share/tomcat6/bin/catalina.sh. Create a line in /usr/share/tomcat6/bin/startup.sh to set CATALINA_OPTS to have the desired flags, and then export CATALINA_OPTS as an environment variable. (This looks like it will get picked up by catalina.sh.) The last option sounds like the best one, and it's advocated (without explanation of why) at http://serverfault.com/questions/121038/increasing-javas-heapspace-in-tomcat-startup-script. But I wanted to get a second opinion. Anyone want to confirm that there isn't a better way?

• Changing Vim Home Directory

  - by mcaaltuntas

  Previously I've been using vim without any problems. However a few months ago our company made some network and security updates. After that whenever I plug a network cable into my laptop, it creates a network shared drive "H" with my company name and when I try to open vim it doesn't load plugins and other things that are in my vim home directory. I have found the reason but I don't know how to solve it. The problem is that these network updates changed our HOME directory. When I write: echo $HOME It prints H. Before plugging in a network cable my home was C:\Users\blabla. How can I change my HOME variable? When I run set it prints: C:\Windows\System32>set | findstr /R "^HOME" HOMEDRIVE=H: HOMEPATH=\ HOMESHARE=\\companyname\blabla\username$
