• Best open source server notification software

  - by Adam Evers

  I am looking for an open source notification/monitoring software which will work much like growl does with a mac. It would be awesome if I could receive certain messages to my mac computer from my server when lets say it restarts or some predefined error happens etc. Anyone know of anything like that? I know of Nagios but I am thinking not as complex.

• Devices renamed with udev not working, original device node still there

  - by skerit

  I'm trying to rename certain video devices using udev. Here's a rule (broken down for readability): ACTION=="add", SUBSYSTEM=="usb", ATTR{busnum}=="1", ATTR{devpath}=="2", ATTR{idVendor}=="05e1", NAME="video97" It works. /dev/video97 is created But the original /dev/video1 node is STILL there. The even worse, when I try to view the /dev/video97 node in guvcview it doesn't work, while the original node DOES work.

• How cpu writes data to dynamic RAM

  - by Krit

  Hello, I would like to know what kind of electrical signals does a cpu send to a dynamic RAM when it wants to write one bit (a 1 or 0). Is it simply that cpu sends just a single electric pulse, and if that electric pulse's voltage is higher than a certain level, it charges the capacitor to a voltage level that is "1" and if it is at a lower voltage band, it charges capacitor to level that it is "0"?

• Automatic Edit Photoshop Canvas Dimensions in Bulk

  - by Josiah

  On a website that I maintain I am required to edit hundreds of images to have a certain canvas size. The images come in all different shapes and sizes. I am trying to figure out a way to automatically edit them so that I dont have to write ineffective AHK scripts to do it. Is there a feature inside of Photoshop (cs3) to do this? I am more than willing to try different software. Thanks guys!

• PNG Compression

  - by T Pops

  At work, on certain projects I have to manage a lot of images. Most of the time PNG files work the best for what I'm doing. With such a huge amount of images, I've tried using PNG compression with PNG Gauntlet but sometimes the file doesn't really change and sometimes PNG Gauntlet reports it would've made the filesize bigger! Am I just maxing out the compression or is there something more I can do?

• linux macvlan - stop from broadcasting hostname

  - by staticfloat

  I am trying to simulate two different computers on one box, using the macvlan module (which is awesome, by the way) but I have one small problem; When I create the macvlan Ubuntu 11.10 very helpfully starts broadcasting its hostname on both interfaces, creating an amazing amount of confusion for everything that deals with hostnames. Does anyone know how to stop ubuntu from advertising its hostname on a certain interface? Thanks!

• Can I limit remote desktop to a particular network card?

  - by Jack Mills

  I have two routers/internet connections connected to my PC. One is a slower connection with a fixed IP that I use for business, the other is a faster connection I use for day to day surfing. I have to use the fixed IP connection to log onto certain servers (due to security) to work but I'm finding that often my PC will try to use my other internet connection to connect which will get rejected (as it doesn't have the fixed IP). Can I limit remote desktop to use a particular network card to get around this problem. Note: I'm running Windows 7

• Share PC over network

  - by Sachin Verma

  I have a server installed on one local Win7 machine (say as 192.168.2.14:8080/myAPP) and I want to access that server from different computer (say ip as 192.168.2.16). Even they are connected to same network I can't access server from other computer. I guess the problem is in firewall. This is working when I disable firewall and not working when I allow certain ports in windows firewall but keeping firewall on (As a rule to allow incoming connections).

• Where the heck is mod_login? (Joomla)

  - by Joey Adams

  I'm a Joomla newbie, and I'm trying to set up a site to require login access to certain articles. Simply setting the article's Access Level to Restricted makes it disappear rather than prompting for a login. I can't figure out how to make a login page because I can't find any menu items or documentation pertaining to mod_login. I want to set at least one page to require login access. Where do I start?

• Delete registry key or value via a CMD script?

  - by Derek

  How do I edit an already-in-production .cmd script file, in order to have the script delete a certain registry key in the Windows registry? Firstly, is this even possible, and secondly (if that's not possible), could I create a .reg file and execute that file from with the .cmd file? From within the .cmd script, it is not working: del "[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\CurrentVersion\SampleKey]" This method hasn't worked for me either: cmd "\\networkdrive\regfiles\deleteSampleKey.reg" Then from within the .reg file: Windows Registry Editor Version 5.00 [ -HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon ]

  I have an Excel sheet that I'm using to keep track of the status of certain things. I want to have a column which consists of cells containing a repeated drop down that allows you to select (as background) red amber green unknown I don't want any text in this cell, I just want a coloured block. Is this possible? I've tried playing around with data-validation-list (based on range containing all of said colours but to no avail)

• Automatic backup software?

  - by Mehrdad

  Every backup software I've seen (even the ones that claim "continuous" protection) only backs up files periodically -- say, every 5 minutes. What I'm looking for is true continuous backup software, i.e. software that can transparently back up files immediately before they are written to, so that I can be certain I have all the versions of a file that ever existed. Is there any software that does this?

• AD reset user passwords for a security group

  - by Nathan C

  I'm not quite sure if this is possible or not, but I need to force a certain security group's users to have their passwords expire so they'll be forced to change them on next login. The reason for this is because I applied a FGPP (password policy) to this particular group in order to enforce strong passwords. Well, many users have really weak passwords and they won't be changed unless they're forced. Is there a way to do this without forcing everyone to a single password?

• How can I start any application with Guest permissions by default?

  - by Tom Wijsman

  Here are my two questions: How can I start any application with Guest permissions by default? How can I set certain applications not to launch with Guest permissions? For the first bullet, any non-Microsoft signed application I launch should run as the Guest account. For the second bullet, I'm imagining adding menu entries like this would be a nice approach: Set to run as Guest (= default selected entry) Set to run as User Set to run as Admin But how do I do this?

• Why does Kerberos need Ticket Granting Server?

  - by Narsil

  It's probably something fundamental but I can't find a certain statement. Why can't KDC authenticate then provide the service ticket directly. Is it about security or performance or some other thing? Since users don't log in each time they request a service and assumably they will keep logged in for a long time, AS doesn't seem so busy. Why do they have to be seperated?

• Recompile PHP5.3 with mysqlnd on Debian Squeeze?

  - by TheRebel

  My current PHP5.3 installation was compiled with libmysql by default. To run certain mysqli functions, I need the mysqlnd library, but I can't seem to find a step by step guide giving proper description how to recompile PHP 5.3 on Debian 6 with custom settings. All I found was the configuration parameter on the PHP.net manual (http://php.net/manual/en/mysqlinfo.library.choosing.php) saying that this is a compile time decision: $ ./configure --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-mysql=mysqlnd Any ideas how to do it? Thanks!

• Untar with date filter

  - by Don

  Is there any way to untar and only extract those files that are above a certain date including directory structure?? I restored a backup on a play server but it was a few days old. However I have a tar archive of the entire structure that is more up to date and healthy so now I want to extract all files (including directory structure) based on a date filter on the files if possible?

• How can I omit an application from showing up as frequently used in the start menu?

  - by Ben S

  I used to use a certain application very frequently (WinSCP), but I now seldom use it. As such, I explicitly removed it from the start-menu's frequently used list. However, now if I use it even just once, it jumps to the top of the list and I have to remove it manually again. Is there a way I can tell Windows to simply omit the application from the start menu list?

• Monitoring folder diffs across servers with zabbix

  - by Marcus

  Problem: I want to make sure that a certain folder is equal regarding it's contents across my servers. I do not want an automatic filesync to keep them equal, changing is done manually. My initial thought was to once a day calculate some crc/hash on folder and send to Zabbix, and trigger when values differ. Is there any good tools out there that can calculate crc or similar of a folder? Anyone know of another solution that solves my problem?

• If a user is part of two TFS security groups, why do they (appear to) receive the lesser security of the two?

  - by Jedidja

  Given two TFS security groups Admins: Contains a set of Windows users Friends: Contains a Windows Security Group (which is also used as a mailing list) However, the people listed as admins are also part of the security group. It appears that when I lock down the Friends group to certain directories in TFS, the people in Admin also lose their privileges. Is there any way for users to receive the maximum security allowed between multiple groups they are included in? Or have I perhaps setup my TFS security groups incorrectly?

• Software to hold battery at 50% charge level

  - by Mehper C. Palavuzlar

  My Sony Vaio laptop has a built-in program called "Sony Battery Care" which provides a functionality to hold battery at certain levels of charge while operating. For example, I've set it to 50% and the battery is always kept at that level while on AC power. This mode prevents battery degradation and is more effective as I usually use my laptop with AC power. I'm looking for a similar program to use with other laptops with Windows OS; preferably a free one.
