• Conky - How to get weather alerts using rss?

  - by BeSlayed

  Quick question about how to get weather alerts with conky. I'm using the following bit of code: ${execpi 3600 ~/.conky/scripts/conky-rss.sh "http://www.weather.gov/alerts/wwarssget.php?zone=MDZ006"|sed '1,3d'|fold -sw 62} This (correctly) display a message to the effect "There are no weather alerts for ...." when there are no weather alerts. However, when there is an alert, it simply displays a message like "Short-term forecast for ..." with no further information. Any suggestions? How are other people getting weather alert info in their conkys?

• How to switch to user perspective in Blender

  - by Cyanophage

  I've just started using Blender (v2.63) for the first time. I have used a lot of 3d modelling programs in the past but Blender's controls seem to be set up differently and it's taking a while to get used to it. The thing that is really bugging me at the moment is switching from user perspective to front/side/top views. I have my view in perspective mode and I want to switch to front view in orthographic mode and then switch back to the view I had before. It seems that the only way is to press numpad-0 to go to camera view, rotate the screen a bit to get rid of the annoying black outline and then switch it back to perspective mode. Then sometimes when I go back to front view it's in perspective mode which is annoying as you never want front view in perspective, only orthographic mode. My question: Is there a way I can be in my user view in perspective mode, switch to front/side/top views in orthographic mode and then switch back to where I was before in my user mode and be back in perspective mode?

• Remapping Home/End from PC to Mac Via Synergy is not client specific.

  - by DtBeloBrown

  This question asks about the end key but the answers give no examples: http://superuser.com/questions/60052/what-key-works-like-end-using-a-mac-with-synergy If they had, I am guessing that they would likely have run into this problem. Adding lines like the bottom two of this: section: options keystroke(End) = keystroke(Control+Right,myiMac) keystroke(Home) = keystroke(Control+Left,myiMac) to my synergy.sgc in MyDocuments on the winXP machine would work but causes the keys to stop functioning on the winXP machine. Unacceptable. I next tried a compromise: keystroke(End) = keystroke(Control+Right,myiMac); keystroke(End,myPc) keystroke(Home) = keystroke(Control+Left,myiMac); keystroke(Home,myPc) Expecting that to broadcast the keystrokes to both machines regardless of which one was the Active Screen. That and many other variations did not work. What am I doing wrong? Has someone actually done this?

• Find which php scripts cause high CPU with php-cgi

  - by Oli

  Background: I maintain a server for a client who has half a dozen Wordpress sites on. They all have the W3 Total Cache plugin installed and eAcellerator is installed (might be APC). All the PHP sites run through a single batch of fastcgi php-cgi processes (it's actually php-fpm but I'm not sure if that makes a difference). Problem: php-cgi's CPU usage is quite high. Not terminally high but high enough to raise an eyebrow. The client wants to add more sites in the future and I want to avoid becoming CPU limited if I can help it. Question: Is there any way I can find the scripts or even just requests that are causing the high CPU. I realise I might not be able to do anything with the results but it would give me a chance.

• Using Windows 7 drivers in Windows Server 2008 R2

  - by Robert Koritnik

  Maybe I should post this to http://www.serverfault.com. Windows 7 comes with all sorts of signed drivers so there's high probability that all drivers for your machine will be installed during system setup. On the other hand Windows Server 2008 doesn't event though it's practically the same OS when it comes to drivers. But I know that this has a very good reason. It's a server product, not a desktop one. But the thing is that many power users and developers use server OS on their workstations which are normally desktop machines and would need Windows 7 driver spectrum... Question I know I've been reading about some trick on the internet that first installed Windows 7 on the machine, than do something to get either all Windows 7 driver collection or just those installed, and then install Windows Server 2008 and use those drivers. The thing is: I can't seem to find these instructions on the internet any more. If anybody knows where these are please provide the link for the rest of us.

• SQL Server Column Level Encryption - Rotating Keys

  - by BarDev

  We are thinking about using SQL Server Column (cell) Level Encryption for sensitive data. There should be no problem when we initially encryption the column, but we have requirements that every year the Encryption Key needs to change. It seems that this requirement may be problem. Assumption: The table that includes the column that has sensitive data will have 500 million records. Below are the steps we have thought about implementing. During the encryption/decryption process is the data online, and also how long would this process take? Initially encrypt the column New Year Decrypt the column Encrypt the column with new key. Question : When the column is being decrypted/encrypted is the data online (available to be query)? Does SQL Server provide feature that allows for key changes while the data is online? BarDev

• One codec to rule them all

  - by AngryHacker

  I am streaming videos in my house via Windows Media Player Streaming, which is basically DLNA. So theoretically any DLNA compliant device can pick up the stream. However, I've quickly found that this is only one part of the solution. Over the years I've accumulated a ton of video-capable devices. While all these devices can see the Windows Media Player stream, they all speak in different codecs. And frankly, I am confused by codecs. In the beginning, I thought that the codecs were defined by the filename extension they carried (e.g. avi, mp4, wmv, etc...), but after further research, it looks like the extensions are simply containers. Inside an .avi file could reside several different codecs. So my question is this: is there a format/codec that plays equally well on any device.

• Linux box acting as wireless access point to share the internet connection

  - by Suresh

  A linux machine is connected to internet over two interfaces ppp0 and ppp1 using two modems. Also this machine acts as wireless access point through an interface say, eth0 with ip address 192.168.1.1 and acts as gateway for the connected devices through this network with subnet mask 255.255.255.0 Now is it possible to achieve the following: When any of the connected devices through wireless AP needs internet connection linux machine has to use ppp1 interface for internet. If any of the applications on the linux machine needs internet connection linux machine should use ppp0 interface for the internet. Can this be achieved by adding rules to chains in filter/nat tables? If the kernel routing table has a default rule to route the default traffic through interface ppp0, wil kernel completely ignore ppp1 for internet? PS: new to networking and routing concepts, If the question is not clear leave a comment, will try to give more information.

• active directory servers synchronization

  - by Mit Naik

  I have 3 AD servers with windows server 2008 R2 at 3 different places, main server is at datacenter and 2 are in our local office which are at 2 different place. I want to synchornize all the 3 server together, were datacenter server should be central server and rest 2 servers should synch with the datacenter server. Please provide us the steps or tutorial to do this. Also we want that once the changes are done in 1 of the AD server the changes are automatically done in all the servers. For example if I change the password of user in our local server it should be updated in our main AD server and other branch server too. Please provide us the steps or tutorial to do this asap. I have one more question I have already created main datacenter AD as domain.local and other domains as xyz.local and abc.local, how can I replicate the additional AD domains with main datacenter DC, also do we require VPN connection, is there any other way to replicate the servers without using VPN connection?

• My Unicomp Model M is double-striking on a key. What to do?

  - by Alex

  I realize this isn't strictly a computer-related question, but I figured that if there's any place to go for help about a broken keyboard, it would be a power users' forum. The O key on my Unicomp Model M has the tendency to strike twice. In other words, I press the key once, and it sends out two letters. There is probably a mechanical solution to this, but I'm not familiar enough with how these things work to come up with a fix myself. Has anyone had this problem?

• Replicate Oracle to MySQL

  - by Rosdi

  I am developing a web apps, this web application will be using MySQL. Now I need to replicate my client's Oracle database into MySQL, only a few tables will be involved.. a table can be up to 2-3 million rows. I only have SELECT privilege on this Oracle, so don't ask me to install any kind of service on the Oracle machine. I have complete control on the MySQL side however. The replication is only one way (Oracle to MySQL). I can write a simple script to truncate MySQL table and repopulate it every night but I think this is very inefficient, there must be a better way. Is there any free tools I can use? Expensive database replication system is definitely out of the question.

• Can you recover from a backup with bad blocks?

  - by Macbook-Recovery

  The hard drive in my Macbook recently gave up while using it on the plane (dual prop, lots of vibration unfortunately). I have a backup of its contents from a few weeks ago, but there are files that aren't included in it that I would like to recover. As it stands right now, I have it plugged to my macbook by USB. Snow leopard recognizes it, but can't mount it. Therefore, tools like Diskwarrior and Techtools do not work. I started doing a clone of it with Data Rescue 3, but after 7 hours of activity (20% through the drive), it has copied 130 GB of the drive but reports all of the data as "bad blocks". My question is this: Is any data recoverable if the clone is completely composed of bad blocks?

• Company Password Management

  - by Brian Wigginton

  The topic of personal password management has been covered in great detail time after time. This question is aimed at the business or organization that needs to keep track of many unique passwords for many clients. What are some strategies/tools or ideas you all have for accomplishing this task? I was at an Interactive Agency, where we needed to keep track of client DB, ftp, mail... and for different environments for the app so any one client would have up to 3-10 passwords usually. This can get crazy when there are more than 250 clients

• BES and BES Express co-existance

  - by ITGuy24

  Question: Can I deploy BES and BES Express with Exchange 2010? Any tips for doing this if possible? Background: We have a lot of users with personal BlackBerry's and we would like to allow them to start using their devices for receviing corporate email. We don't need full BES features for these users, just the ability to enforce passwords and remotely wipe. Plus users have never wanted to upgrade their data plans to the more expensive BES plans. So BES Express is a great fit. We already have an existing BES, for corporate owned BB's. We want to keep this as is allows us to enforce several policies, not available on BES Express.

• Ubuntu server failing daily

  - by deanvz

  Symptoms: Server becomes unresponsive - Increase in load, all services stop Loss of connectivity - Ping/SSH Flush MySQL hosts after reboot - As MySQL refuses new connections Intermittent Apache crashes Generally happens early morning hours - 2 days of the week are however excluded Changes made: Updated the OS - to Ubuntu 10.04.4 LTS Not sure if the MySQL server was also updated in the process Current MySQL version - mysql Ver 14.14 Distrib 5.1.63, for debian-linux-gnu (x86_64) using readline 6.1 Updated Plesk from 10.4.4 Update #47 to 11.0.9 Update #23 Rebooted on almost daily basis All crons stopped for the times corresponding to the server crashes Created a MySQL log to monitor the lock times on queries Possible causes: Failing hardware Incorrect software configuration (MySQL, Apache etc) Responsibilities: Small webserver Runs our billing system - WHMCS Responsible for CRONs Bulk-email solution - No delivery times coincide with server crashes Proposed solutions: Move machine over to VM Format and restore the Plesk server backup and take it from there?

• How do you remove old Windows Vista Backups?

  - by leeand00

  I've been backing up my Vista box using Complete PC backup for quite a while now, and I was just wondering how it is that you remove old backups when your backup drive is to full for another backup. I recently received the following error: The backup did not complete successfully. An error occurred. The following information might help you resolve the error: There is not enough space to save the backup files. Free up disk space or change your backup settings. (0x81000005) I don't see anything in the settings for the backup to change this. Do I have to mount the backup to delete an old backup? If so where is that file located? Update Posted my question here

• Add unallocated space to lvm

  - by Newbie

  I shrunk my windows partition and now have 10 GB of unallocated space that I now want to use to grow my / partition which is an ext4 in an lvm. I'm running Fedora 12. I ran system-config-lvm but the "Initialize Entry" button is greyed out. The unallocated space is not adjacent to the lvm but I cannot move the partitions in GParted like I was able to with ext3 in the past. I cannot create a new partition either as it says it cannot have more than 4 primary partitions. I don't see any option to create an extended partition. So my question is, how do I add that unallocated space to the lvm so I can grow the size of the / partition? I don't want to reinstall Fedora.

• GRUB Problem or Hardware Problem?

  - by Nikit Batale

  I have Windows XP Professional and Ubuntu Karmic Koala 9.10 on dual boot. I often get a GRUB loading failed error during boot-up. Or sometimes, when I try to boot into either Ubuntu or XP, I get a Could not read from source error. Now this is funny. After getting one of the above errors, if I simply unplug the SATA cable from Hard Drive end and plug it again, the problem gets solved. So what and whose problem is it? GRUB or My Hardware ? P.S.: I was suggested on StackOverflow that ServerFault is the right place for this question.

• Prolific USB-to-Serial Comm Port significantly slower under Windows 7 comparing to Windows XP

  - by Dmitry S

  I am using a Prolific USB-to-Serial adapter based on the Prolific chip to use with a device on serial port. I have the latest version of the driver installed: 1.3.0 (2010-7-15). When I use my device with this adapter on my main Windows 7 (32bit) system it takes 8-9 seconds to send a command through to the device. However, when I do the same thing on a different Windows XP system (an old laptop I borrowed for testing) it only takes 2-3 seconds. I have made sure that the port settings and other variables are the same between systems. I also tested on a third laptop (also running Windows 7) and again got a significant delay. So the question is if anyone else experienced the same problem and found a solution. I would like to avoid moving to an XP system for what I need to achieve so that's my last option.

• FOR command cannot see hidden files

  - by Synetech

  I’m struggling with one of the most frustrating bugs I’ve ever come across. Bug description:   The for command of the command-interpreter cannot see hidden files. Reproduction steps: Create a temporary directory Create a few files Assign a variety of attributes to the files (including hidden) Use a command like for %i in (*) do echo "%i" Expected results:    All files are processed in the for loop either by default or though a switch. Actual results: Files with any attribute other than hidden are processed; files flagged as hidden are skipped There is no switch to the for command to allow it to process hidden files Implications:    There is no way to process all files from the command-prompt. Question:    How the heck can hidden files be processed from the command-prompt or batch-files (at least in Windows if not DOS)?

• Which software could I use to setup a 4in6 IP tunnel (RFC 2473) on GNU/Linux

  - by Mildred

  Here is my problem. I have a server A that has two IP addresses. One public IPv4 and one IPv6. Server B has only one IPv6 address. I want to host most of my services on server B (because I have more disk space on it, I can control it better) but I need the IPv4 of the server A. I would like to set up a 4in6 tunnel (RFC 2473) between A and B so that I can transfer the traffic from the IPv4 address in A to B. If needed, I can request another IPv4 address on the server A, but I'd prefer not to. My question is: which software use to do the 4in6 tunnelling? I suppose OpenVPN can do the thing, but is there any implementation of the 4in6 protocol on Linux? A little more challenging: the IPv4 address comes from a venet interface, which cannot be bridged. How could I transfer ownership of this address I don't use on server A to the server B? Thank you

• Chromebook, Crouton & “External Drive” is it possible to rename the folder?

  - by Cyril N.

  I have a Chromebook where I installed Crouton. I have plugged an SD Card and Chromebook detects it as "External Drive". In my Ubuntu instance, it's located at /media/removable/External Drive/ but this poses some problems for executing some applications I have installed on that external drive. In order to fix the problem, I need to remove all the spaces in the path, which is located in "External Drive". My question is simple, is it possible to move/rename the mount name "External Drive" to something else and doing it automatically at every mount/boot ? Thank you for your help !

• LAMP/TURNKEY LINUX/VIRTUAL BOX: Manipulating Files on a Virtual Machine

  - by aeid

  I am running Ubuntu 9.10 and I want to install turnkey linux's LAMP server on my machine to test out my code. I installed Turnkey LAMP via VirtualBox and it seems to be working because I can access the http://localhost. My question is: How do I manipulate files via VirtualBox? For example, if I had installed LAMP on my machine (not on a virtual machine), I could easily add/edit/delete files in the var/WWW folder. Where is the equivalent of "WWW" folder on Virtualbox and how can I interface with it? Thanks,

• Problem running mercurial against symlinked .hgrc file under Cygwin/Windows 7

  - by emptyset

  This is not a question about handling symlinks in the mercurial repository. I have this setup at work where I keep my dotfiles in a separate directory (.configuration) that I can use to synch my dotfiles between cygwin/windows and linux, then use symlinks instead of dotfiles in the home directory. So, I have the symlink ~/.hgrc -> .configuration/.hgrc in my home directory. After setting this up, mercurial complains thus: $ hg st hg: config error at C:\Users\aaf\.hgrc:1: '!<symlink>ÿþ.configuration/.hgrc' Removing the symlink and replacing it with the actual file works, so the contents of the .hgrc file are not at fault. I can live with that, I suppose, but I'd like to know why this happens. All other tools I've configured the same way work great with symlinked dotfiles.

• adding keyboard shortcuts for OSX terminal or xterm

  - by I J

  Is there a way to add a keyboard shortcut for a terminal command in OSX. Basically most of the times i open the terminal app in MAC in order to ssh into a certain server foo. What I want to do is add a keyboard shortcut (say ^k) so that on a terminal when I do that, it runs "ssh foo" in the terminal. Thanks PS: I think if there is something for the xterm in linux then it should work for the terminal too. So this might not be an OSX specific question. PS2: I want the shortcut to do carriage return with the "ssh foo". If its just "ssh foo", then I can write an alias in .bashrc. My goal is to minimize the number of keystrokes I've to do at the end of the day.
