• How to tell Vim to extend the background color to the whole screen?

  - by chiborg

  I have an issue with the Vim color schemes: The background color does not fill the whole screen. For example, in the "blue" color scheme the whole screen should turn blue. Instead, the blue background only extends to the end of each line. Is this a setting in the console I'm missing or is this an issue with my vim default settings? I'm only having this issue with Ubuntu 10.10. echo $TERM outputs xterm-color. [Update]: To eliminate error sources my minimal ~/.vimrc looks like this: filetype plugin on colorscheme blue syntax on /etc/vim/vimrc contains the unchanged defaults of Ubuntu

• allowing 2 VM's to communicate RED HAT 64 bit

  - by ????? ????????

  My physical PC is running 2 VMs on virtualbox. Both of the VM's are linux 64 bit. I am going through this tutorial: http://www.cyberciti.biz/faq/rhel-centos-fedoracore-linux-network-card-configuration/ in order to expose both of their IP's so that they can speak to each other. Mike Schwager November 25, 2009 at 10:55 pm Whoops! In section 3, you forgot about editing /etc/hosts. I believe RedHat comes complete with the system’s host ip address set up in /etc/hosts. Don’t forget to give it a look. I agree with Mike because after I looked into the /etc/hosts files, it has just default localhost stuff in it. How should I reconfigure the hosts file?

• Monit and Thin and Unfound Gems

  - by TenJack

  I've been using Monit to monitor my Thin server and everything was working until I upgraded my Rails version from 2.3.4 to 2.3.14. Now when I try and start Thin using monit it gives me an unfound gem error: Missing the Rails 2.3.14 gem. Please `gem install -v=2.3.14 rails` I thought this may be a GEM PATH issue and also tried setting the GEM_HOME and PATH variables in the start command: check process thin3001 with pidfile /home/blahblah/apps/Vocab/shared/pids/thin.3001.pid start program = "/usr/bin/env PATH=/usr/lib/ruby/gems/1.8/gems GEM_HOME=/usr/lib/ruby/gems/1.8/gems /usr/bin/ruby /usr/bin/thin -C /etc/thin/vocab.yml start -o 3001" stop program = "/usr/bin/ruby /usr/bin/thin -C /etc/thin/vocab.yml stop -o 3001" if totalmem > 150.0 MB for 5 cycles then restart group thin It's strange because if I run the start command in the console it works fine, it's only within monit that I get the missing Gems error.

• [Ubuntu 10.04 Desktop] Unable to get Webmin or Vboxdrv to auto start on boot

  - by Matthew Hodgkins

  Ever since installing Ubuntu 10.04 I've had issues getting things to auto-start.

• Does any know fix/cause of USB drives that lose connection

  - by Burch Kealey

  I have been having significant problems trying to copy files to a USB drive (G0-Flex 1.5 tb) No matter what I use to try to copy the files (python code, Windows copy and paste or Drobo Copy utility) I ultimately get a failure. The failure is always some indication that the device is not ready or able to be written to. I am pretty sure the problem is that the drive is losing its connection. I have done everything I can find so far including setting the USB Root hub to never turn off the power, I updated some usb drivers etc. I have found references to this problem primarily with Win7-64 bit. I have also had USB connection problems with other devices- we kept losing a connection to our Bravo Disc Publisher when we went to Win7 and finally bought a newer model and have not had problems since. Any pointers about diagnosing and or understanding the problem would be appreciated.

• TFS 2010 Build: Dealing with the API restriction error

  - by Jakob Ehn

  Recently I’ve come across this error a couple of times when running builds that exeucte unit tests using Test containers: API restriction: The assembly 'file:///C:\Builds\<path>\myassembly.dll' has already loaded from a different location. It cannot be loaded from a new location within the same appdomain. Every time I’ve got this error, the project has been a web application, and the path to the assembly points down to the _PublishedWebsites directory that is created beneath the Binaries folder during a team build. The error description really says it all (although slightly cryptic), when using test containers, MSTest needs to load all assemblies and see if they contain any unit tests. During this serach, it finds the ‘myassembly.dll’ in two different locations. First it is found directly beneth the Binaries folder, and then it is alos found beneath the _PublishedWebsites\Project\bin folder. The reason is that the default setting for test containers in a TFS 2010 build definition is **\*test*.dll:   This pattern means that MSTest will search recursively for all assemblies beneath the Binaries folder, and during the search it will find the MyAssembly.dll twice. The solution is simple, set the Test assembly file specification property to *test*.dll instead, this will disable the recursive search:

• Monogame - Shader parameters missing

  - by Layoric

  I am currently working on a simple game that I am building in Windows 8 using MonoGame (develop3d). I am using some shader code from a tutorial (made by Charles Humphrey) and having an issue populating a 'texture' parameter. I'm not well versed writing shaders, so this might be caused by a more obvious problem. I have debugged through MonoGame's Content processor to see how this shader is being parsed, all the non 'texture' parameters are there and look to be loading correctly. Shader code below #include "PPVertexShader.fxh" float2 lightScreenPosition; float4x4 matVP; float2 halfPixel; float SunSize; texture flare; sampler2D Scene: register(s0){ AddressU = Clamp; AddressV = Clamp; }; sampler Flare = sampler_state { Texture = (flare); AddressU = CLAMP; AddressV = CLAMP; }; float4 LightSourceMaskPS(float2 texCoord : TEXCOORD0 ) : COLOR0 { texCoord -= halfPixel; // Get the scene float4 col = 0; // Find the suns position in the world and map it to the screen space. float2 coord; float size = SunSize / 1; float2 center = lightScreenPosition; coord = .5 - (texCoord - center) / size * .5; col += (pow(tex2D(Flare,coord),2) * 1) * 2; return col * tex2D(Scene,texCoord); } technique LightSourceMask { pass p0 { VertexShader = compile vs_4_0 VertexShaderFunction(); PixelShader = compile ps_4_0 LightSourceMaskPS(); } } I've removed default values as they are currently not support in MonoGame and also changed ps and vs to v4 instead of 2. Could this be causing the issue? As I debug through 'DXConstantBufferData' constructor (from within the MonoGameContentProcessing project) I find that the 'flare' parameter does not exist. All others seem to be getting created fine. Any help would be appreciated.

• Why does integrity check fail for the 12.04.1 Alternate ISO?

  - by mghg

  I have followed various recommendations from the Ubuntu Documentation to create a bootable Ubuntu USB flash drive using the 12.04.1 Alternate install ISO-file for 64-bit PC. But the integrity test of the USB stick has failed and I do not see why. These are the steps I have made: Download of the 12.04.1 Alternate install ISO-file for 64-bit PC (ubuntu-12.04.1-alternate-amd64.iso) from http://releases.ubuntu.com/12.04.1/, as well as the MD5, SHA-1 and SHA-256 hash files and related PGP signatures Verification of the data integrity of the ISO-file using the MD5, SHA-1 and SHA-256 hash files, after having verified the hash files using the related PGP signature files (see e.g. https://help.ubuntu.com/community/HowToSHA256SUM and https://help.ubuntu.com/community/VerifyIsoHowto) Creation of a bootable USB stick using Ubuntu's Startup Disk Creator program (see http://www.ubuntu.com/download/help/create-a-usb-stick-on-ubuntu) Boot of my computer using the newly made 12.04.1 Alternate install on USB stick Selection of the option "Check disc for defects" (see https://help.ubuntu.com/community/Installation/CDIntegrityCheck) Steps 1, 2, 3 and 4 went without any problem or error messages. However, step 5 ended with an error message entitled "Integrity test failed" and with the following content: The ./install/netboot/ubuntu-installer/amd64/pxelinux.cfg/default file failed the MD5 checksum verification. Your CD-ROM or this file may have been corrupted. I have experienced the same (might only be similar since I have no exact notes) error message in previous attempts using the 12.04 (i.e. not the maintenance release) Alternate install ISO-file. I have in these cases tried to install anyway and have so far not experienced any problems to my knowledge. Is failed integrity check described above a serious error? What is the solution? Or can it be ignored without further problems?

• MacPorts, how to run "post-destroot" script

  - by Potatoswatter

  I'm trying to install MacPorts gdb; it seems to be poorly supported… Running "port install" installs it to /opt/local/libexec/gnubin/gdb, but the intent doesn't seem to be to add that to $PATH. The portfile doesn't define any parameters for port select which is typically used to set a MacPorts installation to handle default Unix commands. But it does include these lines: foreach binary [glob -tails -directory ${destroot}${prefix}/bin g*] { ln -s ${prefix}/bin/${binary} ${destroot}${prefix}/libexec/gnubin/[string range $binary 1 end] } This is buried under an action labeled post-destroot. destroot is a MacPorts command but post-destroot is not. The script is apparently not run by port install or port activate, or if it's failing it's doing so silently. Is there a better approach than creating the links manually?

• email handling with inbox.py and nginx

  - by Matt Ball

  I have a Flask web application running behind gunicorn and Nginx. Nginx proxies any traffic to ivrhub.org to the correct flask app. I would very much like to use inbox.py to process some incoming email. Running inbox.py's example on my server and then sending an email to [email protected] does not work as I intended. The inbox.py server does not seem to receive anything but the email also does not bounce. I'm missing something conceptually -- is there a DNS setting I need to configure or something I need to adjust with Nginx?

• The Boss Answer: What is a relational database?

  - by kce

  I'm mostly a system administrator and I don't directly work with databases other than installing them, setting up accounts, granting privileges, and so on. I realized that if The Boss walked up to me and asked, "What is a relational database?" I probably couldn't give a satisfactory answer... I'd maybe mumble something about data being stored and organized by categories which you can query with a special programing language (i.e., SQL). So could someone give a good "Boss Answer" for what a relational database is? And maybe how its different than just storing data on a file server? Bonus points for clever but accessible analogies and explaining tables, columns, records and fields. I'd define a "Boss Answer" as a quick one (maybe two) paragraph explanation for non-technical folks... mostly your Boss, on those rare occasions they actually ask you what it is you do all day.

• Changing location of ClamAV logging files

  - by GrumpyCanuck

  I've run into a weird problem with ClamAV that I have been unable to resolve, due to a incredibly non-informative error message. I've installed ClamAV via aptitude on an Ubuntu box (ClamAV 0.96.5/13202 according to the system) up on EC2 and it is 100% stock. We have an additional drive mounted under /mnt where we put all our log files. When I start it up with the log files in the default location, it runs just fine. However, if I change the configuration file from /var/log/clamav/clamav.log to /mnt/clamav/clamav.log I get the error ERROR: Can't open /mnt/clamav/clamav.log in append mode (check permissions!). ERROR: Can't initialize the internal logger It's the same file with the same permissions on it, just in a different location. Any thoughts or tips on how to resolve this problem would be greatly appreciated.

• What is this jumper for on my new motherboard?

  - by jasondavis

  I am building a new PC, I just got my motherboard in the mail today. It is a ASRock X58 Extreme 3. I am reading over the manual for it and one of the jumpers says this. There is a 3 pin jumper labeled 1 2 3, with pins 1 and 2 shorted by default it is "+5v" If I manually change it to short jumper pins 2 and 3 instead of 1 and 2 then it will be "+5vSB (standby) for PS/2 or USB wake up events. So I am confused as to exactly what this is for. Can someone explain what it means, why I would want one other the other?

• Refurbished System Windows License Key and OEM Media

  - by Timothy R. Butler

  According to this question, it is legal to use a Windows 7 OEM license that is presently installed as a 32-bit install with a 64-bit version of Windows 7. With that in mind, I purchased several refurbished systems through TigerDirect. When I received the computers today, I found that they have a Windows 7 license key attached to them that says it is a "refurbished key." A flyer in the box also seemed to imply that this key would not work with regular OEM media. Has anyone tried using regular OEM media with a refurbished key? I had hoped to create a new 64-bit WIM image that I could use on these systems, but I don't want to try replacing the default install with this new 64-bit install only to find that the key won't validate. If it requires a special customized image, is it possible to convert another type of Windows 7 disc into the required sort much as one can convert a retail disc to an OEM one (and vise versa)?

  - by Asian Angel

  What happens when you mix the Legend of Zelda with the 80s high school scene? Something fun and cheesy that makes you wish there really was a movie based on this! From YouTube: In this charming critically-acclaimed tale of first love, Link, an eternal optimist and adventurer, seeks to capture the heart of Zelda, an unattainable high school beauty and straight-A student. He surprises just about everyone-including himself-when she returns the sentiment.

• Converting text file to epub?

  - by jamesh

  I have a bunch of book length text files I'd really like to read on my EPUB reader (as it happens FBReaderJ). What would be the best route to convert them? I have access to OSX and Linux (Ubuntu). Probably happiest with a command line, but would setting for a GUI for batch conversion. My criteria for success are really based upon the shortfalls I have found with Calibre must do the whole book at least a guess of what the title/author may be. Minimum the source filename for the title. hygienic with files it uses - tidies up after itself (this is less important) doesn't try to be an all-in-one library manager (again, less important). is lenient in parsing special characters (e.g. < and & characters).

• Uploading.to Uploads Files to Multiple File Hosts Simultaneously

  - by Jason Fitzpatrick

  If you’re looking to quickly share a file across a variety of file hosting services, Uploading.to makes it a cinch to share up to 10 files across 14 hosts. The upload process is simple. Visit Uploading.to, select your files, check the hosts you want to share the file across (by default all 14 are checked), add a description to the collection, and hit the Upload button. Uploading.to will upload your file to the various hosts; during the process you’ll see which hosts are confirmed and which have failed. We had 2 failures among the 14 hosts which still left the file mirrored across a sizable 12 host spread–not bad at all. When you’re ready to share the file hit the Copy Link button at the bottom of the screen and share it with your friends. They’ll be directed to Uploading.to and will be able to select from any of the hosts the file was successfully mirrored across. Uploading.to is a free service and requires no registration.

• Sensei mouse sensitivity

  - by Marcelo

  I've recently acquired a Steelseries Sensei. Despite being a great mouse, I'm having some trouble finding settings that I can get used to... The mouse engine allows me to set a CPI from 0 to 5700. It also allows me to set it even higher, calling it "DCPI" (Double CPI), from 5701 to 11400. On Window's Control Panel, there's a "Pointer Speed" slider and a "Enhance Pointer Precision" checkbox (wording may be different as I use a non-english version). The majority of games allow me to set an in-game "Mouse Sensitivity". Some games let me use a "Raw mouse input". I'm already familiar with the basics of CPI/DPI - "higher CPI means less hand movement", but what are the differences between all those options? Is there a "better" or "worst" setting?

• Settings on php.ini ignored

  - by bfavaretto

  I can't get my server to obey the settings from php.ini (I'm trying to change memory_limit and upload_max_filesize). As far as I can tell, I'm editing the correct file. phpinfo() gives: Loaded Configuration File /etc/php.ini The file permission is 644. There are also some extra .ini files on /etc/php.d, but none include any of the keys I'm trying to change. No matter what I do, phpinfo reports the default values on both "Local" and "Master" columns. I also scanned my Apache config files, but found nothing related to PHP (besides loading the PHP module). The only way I was able to change those settings was by adding some php_value lines to my .htaccess. Is there something obvious I'm missing? This is a virtual server, and I can perform root commands with sudo. I'm running Apache 2.1.3 and PHP 5.3.3.

• Squeezing hardware

  - by [email protected]

  It's very common that high availability means duplicate hardware so costs grows up.Nowadays, CIOs and DBAs has the main challenge of reduce the money spent increasing the performance and the availability. Since Grid Infrastructure 11gR2, there is a new feature that helps them to afford this challenge: Server PoolsNow, in Grid Infrastructure 11gR2, you can define server pools across the cluster setting up the minimum number of servers, the maximum and how important is the pool.For example:Consider  that "Velasco, Boixeda & co"  has 3 apps in a 6 servers cluster.First One is the main core business appSecond one is Mid RangeAnd third it's a database not very important.We Define the following resource requirements for expected workload:1- Main App 2 servers required2- Mid Range App requires 1 server3- Is not a required app in case of disasterThe we define 3 server pools across the cluster:1- Main pool min two servers, max three servers, importance four2- Mid pool, min one server max two servers, importance two3- test pool,min zero servers, max one server, importance oneSo the initial configuration is:-Main pool has three servers-Mid pool has two servers-Test pool has one serverLogically, we can see the cluster like this:If any server fails, the following algorithm will be applied:1.-The server pool of least importance2.-IF server pools are of the same importance,   THEN then the Server Pool that has more than its defined minimum servers Is chosenHope it helps
