• 3 Monitors 2 different graphic cards

  - by Michael

  I am looking to add a third monitor to my workstation. I currently have 2 monitors connected to a geforce gt 120. I am wanting to find the cheapest solution on adding another monitor, I have a old ati x300 laying around and wanting to know if I would be able to use that to power the other monitor and if it would conflict with my other graphic card (I am not a gamer). What I want to do is have the at x300 power 1 monitor via dvi and the gt 120 power 2 monitors via vga and dvi. Thanks edit: im running windows 7 64bit

• Interview questions for programming tutor?

  - by Emmett Gear

  My family is looking for a programming/computer science tutor. Personally, I want to learn Java or some other brand of web programming. I am best described as a PC "power user." I have never programmed in the past and would like a good jump start. I am a very quick learner and do not expect the tutor to have to teach me the ultra basic stuff that I can learn myself. My son also needs a programming tutor. He just got into Carnegie Mellon as a computer science major. Having done only robotics and mathematics in the past he is very nervous that he does not have the same level of knowledge as his future classmates. I need some help coming up with a list of questions to ask potential tutors and some criteria to judge them by. Thanks! Edit: So far I have come up with just the obvious... Where did you receive your education? What languages are you familiar with? How long have you been tutoring? What made you decide to become a tutor? What software projects have you worked on? What work references can you give me? How much do you charge?

• Restrict Overriding memory_limit in php.ini

  - by Rohit Batra

  We have a issue that just came to our notice, some of our developers used ini_set('memory_limit', -1) to over-ride the php.ini memory_limit settings in their code files. Due to which sometimes our Memory/CPU usage is way far more than usual and we even have experienced server hanging/crashing many times. Is there any way to restrict these changes for certain params like memory_limit, upload_max_filesize & post_max_size? Users should not be able to edit them after a certain limit set? Sorry if i asked a dumb question, tried searching but there was no reference to this only found answers asking for increasing these parameters.

• Plesk 9 - Client panel access via client domain, not server host name

  - by Ben

  I've setup a Plesk 9 vps recently. The plesk admin is accessible at, say, http://superawesomedomain.com:8443. I'm setting up a couple of client domains on the server. I'd like clients to be able to access plesk via a similar url, but instead it would be something like http://inferiorclientdomain.com:8443. This works ok in a sense, but it always redirect the request for inferiorclientdomain.com:8443 to superawesomedomain.com:8443. I'd like the control panel access url to remain on inferiorclientdomain.com. Is that possible? EDIT: System Info. Plesk 9.5.2 on CentOS 5 (Build 95100504.12)

• Trying to recover deleted Ubuntu partition

  - by user110984

  I made a mistake in logging into my 200 GB Ubuntu partition. I could not access Grub after that. Using a live CD I then ran Boot_Repair and apparently deleted the partition, I guess because I ran it from my 70 GB Windows partition. I can send the results of boot_info before that and of Boot_Repair. Then I ran TestDisk, which apparently found only dev/sda/ -320GB / 298 / GiB - WDC - WD3200BEVT-22A23T0 (Was there any more I could have done with TestDisk? I looked at the TestDisk_Step_By_Step example and found no way forward given that no other partitions turned up) I have run gpart and found this: /sda1 - 15 GB /sda2 - system reserved /sda3 - 70.15 GB /sda4 - extended 212.84 unallocated - 209.10 /sda5 - unknown 3.74 . I have been told I can recover the partition using gparted's Rescue start end command, but I don't know what to enter for start and end. [--EDIT: TestDisk Deeper Search stated that "the following partitions can't be recovered" and listed a 220-GB Linux partition 6 times. Then it stated that "The current number of heads per cylinder is 255 but the correct value may be 128" and I could try to change it in the Geometry menu (because apparently these are overlapping partitions) So should I do that?--]

• There is not enough space on the disk when there is?

  - by Lee Tickett

  Permissions are fine (inherited) and checking effective permissions everything is AOK. As you can see i can make a file in the docs folder but not the pdf_docs subfolder. The folder has a lot of files and is quite large- i wonder if i've reached a limit? I couldn't find anything on google. Size: 51.0 GB (54,819,804,885 bytes) Size on disk: 52.0 GB (55,925,719,040) Contains 554,697 Files EDIT I've just checked and i can delete files... and for every file i delete i appear to be able to create a new one. This definitely points toward a limit in terms of number of files?

• Determining End of Line Delimiter

  - by Michael Merchant

  How do you verify what the delimiter for a file is? I'm using eclipse to edit a script file on my windows system that I use to deploy on my unix server. The script specifies file names and I'd like to be certain that eclipse is saving the files with unix end of line delimiters. I've set my preferences to use the Unix Line Delimiter on new files using: Window > Preferences > General > Workspace > "New text file line delimiter" And have changed my script file's line delimiter using. File -> Convert Line Delimiters To Is there a way (preferably with the eclipse IDE) to check that there is no "\r"?

• Software vs Network Engineer (Salary, Difficulty, Learning, Happiness)

  - by B Z

  What are your thoughts on being a Software Engineer vs a Network Engineer? I've been on the software field for almost 10 years now and although I still have a great deal of fun (and challenges), I am starting to think it could be better on the "other" side. Not to degrade network engineers (i know there are many great ones out there), it seems (in general) their job is easier, the learning curve from average to good is not as steep, job is less stressful and pay is better on average. I think as software developer I could make the switch to networking and still enjoy working with computers and feel productive. I spend an enormous amount of time learning about software, practices, new technologies, new patters, etc...I think I could spend a much smaller amount of time learning about networking and be just as "good". What are your thoughts? EDIT: This is not about making easy money. Networking and Software are closely related, I love computers and programming, but if I can work with both, make more money and have less stress in my life and can spend more time with my family, then I am willing to consider a change and hence I am looking for advice that Do or Don't support this view.

• how to make a continuous machine gun sound-effect

  - by Jan

  I am trying to make an entity fire one or more machine-guns. For each gun I store the time between shots (1.0 / firing rate) and the time since the last shot. Also I've loaded ~10 different gun-shot sound-effects. Now, for each gun I do the following: function update(deltatime): timeSinceLastShot += deltatime if timeSinceLastShot >= timeBetweenShots + verySmallRandomValue(): timeSinceLastShot -= timeBetweenShots if gunIsFiring: displayMuzzleFlash() spawnBullet() selectRandomSound().play() But now I often get a crackling noise (which I assume is when two or more guns are firing at the same time and confuse the sound-device). My question is whether A) This a common problem and there is a well-known solution, maybe to do with the channels or something, or B) I am using a completely wrong approach to the task. I had a look at some sound-assets for other games and they used complete burst with multiple shots. I suppose I could try that, but I would like to have organic little hickups in the gun-fire (that's what the random value is for) to make the game more gritty and dirty. I am using Panda3D, but I had the exact same problem in PyGame and SDL. [edit] Thanks a lot for the answers so far! One more problem with faking it though: Now how do I stop the sound? Let's say I have an effect with 5 bangs... *bang* *bang* *bang* *bang* *bang* And I magically manage to loop it so that there's no gap or overlap if the player fires more than 5 shots. Now, what do I do if the player stops firing halfway through the third bang? How do I know how long to keep playing the sample so that the third bang is completed and I can start playing the rumbling echo of the last shot? Of course I can look up the shot/pause timing of that sound-sample and code accordingly, but it feels extremely hacky.

• Nohup & Sass: Process keeps running but, after a while, *.scss files do not get compiled

  - by maurits

  I am using Sass on a CentOS 5.8 server and want it to keep running after SSH logout, so that other users can edit *.scss files for days or even weeks to come without any need to start the program each time they login (in fact, they don't even have SSH access). I have used the following command from this question/answer: $ nohup sass --watch path/to/scss/files:path/to/css/output/files & Then, I log out of the SSH session and the process keeps running. It all works fine (logging in again and using touch to create a test file (test.scss) correctly triggers the creation of the corresponding test.css file) for the first few minutes, but after a while the *.scss files stop getting compiled... However, ps aux | grep 'sass' Shows that the process is still running. Anybody knows what am I doing wrong?

• OS X clients ignoring Windows print server permissions

  - by Ilumiari

  I'm in the process of testing a Windows Server 2008 R2 print server for a mixed OS X/Windows environment. Any security permissions (AD groups) I set for the printers on the print server are not honoured by the OS X clients. Only if I remove absolutely all permissions for a given printer will an OS X client not print to that printer. The Windows clients honour the permissions as expected. The PrintService log doesn't record any activity when an unprivileged Windows client attempts to print, and records a typical print job when an unprivileged OS X client attempts to print. Has anyone encountered this problem before and have a fix? With 600-700 clients, a number of which are dual-booting, restricting by IP address is not viable. EDIT: The jobs are definitely going through the print server, they show up in the logs with their AD credentials.

• Where can I find a list of the highest resolution monitors for sale?

  - by speedmetal

  I am always on the lookout for the latest and greatest monitors, but for some reason, I have never found a good resource for this information. And while we know months in advance what new processor will be released, it doesn't seem like we ever know what new monitors will be released until they are. I am tempted to buy a Dell 3008WFP, but since the 30" 2560x1600 monitors have been out for 6 years, I would expect something better is about to be released. Where can I find out what is available in the high resolution / widescreen market and what is soon to be released? EDIT: I did finally find a resource for this information: Comprehensive List of IPS Based LCD Monitors However, if anyone finds another similar or possibly better resource, I will give it a correct answer mark. Thanks!

• Why is my hosts file not working?

  - by elliot100

  I've been using the hosts file to for local website development, and it's recently stopped working. No entries other than localhost resolve. I've simplified to test, so it now contains only 127.0.0.1 localhost ::1 localhost 127.0.0.1 test.dev localhost responds to ping, test.dev does not. The file is called hosts with no extension It has no trailing spaces It's saved in C:\WINDOWS\System32\drivers\etc which matches the value of HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\DataBasePath Oddly, despite UAC being on, I can edit, delete and save the file without admin permissions No proxy is being used, PC is not connected to network for testing Stopping the DNS Client service seemed to resolve the issue for a few minutes, test.dev briefly resolved but doesn't any more. Only firewall is Windows' Machine has been restarted. Is there anything else I should try?

• What advantages does developing applications for smartphones have over developing the same application as a web application?

  - by Alfredo O

  Let's take the Facebook application as an example. Why did they develop an application when the users could just access to their page and do the same? For me that represents more maintenance and more cost because for each feature added to the web application that feature will have to be added to the smartphone application as well. So why would I want to develop more than once (for each patform iOS, Android, etc) when I could just have one web application? What benefits do I get? The only one that comes to my mind is GPS feature. EDIT: My question is more oriented towards business applications that are going to be used only by some members of the company, it's not about selling the application (private use). So contrary to what some answers say about that by developing as a smartphone application it will benefit from more sells because of the "smartphone stores" for me this point is not important because the application is for private use. By developing the application as a web application it means that it can be accessed through smartphone browser and also in a PC (any capable browser), but developing as a native application would limit this to only some kind of smartphone so we would be limiting the use. On the other hand developing it as a web application means that in order to access the application an Internet connection must be available. So keeping this in mind how would you convince your boss to write the application for a given smartphone platform (iOS/Android) vs developing it as a web application?

• Screen is black at login screen if display driver is enabled

  - by Amir Rachum

  I have a Lenovo x200 and recently its screen didn't work, so I took it to a repair lab. The guy told me they replaced the screen inverter. I powered up the laptop and the ThinkPad logo was shown, so I was happy. When I got home the computer would boot up, then instead of the logon screen, I got a black screen. Went to safe mode, disabled the display adapters, reset the computer, and I got a clean boot. Then I tried to reinstall the drivers, and it just led to the same condition. My video card is (from device manager): Mobile Intel(R) 4 Series Express Chipset Family. Now my laptop works as I'm working with display drivers disabled, but without display drivers I can't watch movies, etc. Any solution to this problem? Edit: I plugged in an external monitor and it works on it with display drivers enabled. However, it does not find the laptop monitor.

• Ubuntu won't suspend anymore, but it did upon install.

  - by Bruce Connor

  I fresh installed Ubuntu 10.10 back when it came out, and my laptop was suspending fine. All of a sudden, I can't get my laptop to suspend anymore. It's an HP Pavilion dv2-1110, but I don't think it's a hardware issue, here's why: It suspended fine upon first install. I haven't installed any new kernels since then, but I have installed tons of packages, so it's probably a package. The suspend and hibernate options disappeared from the shutdown menu. If I press my keyboard's suspend button (or if I close the lid) I get the following message: If I try the command pmi action suspend, I get the error message: Error org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.Hal was not provided by any .service files. If I try the command echo -n mem > sudo /sys/power/state I get absolutely no output and no visible effect. What might be causing this behavior? I thought a list of installed packages might be useful, but it's huge and I don't know how to post it here in collapse/expand mode or something. EDIT:Just in case someone asks, none of the installed packages are kdm or anything like that (which would justify the lack of options in gnome's shutdown menu).

• What does dd conv=sync,noerror do?

  - by dding

  So what is the case when adding conv=sync,noerror makes a difference when backing up an entire hard disk onto an image file? Is conv=sync,noerror a requirement when doing forensic stuff? If so, why is it the case with reference to linux fedora? Edit: OK, so if I do dd without conv=sync,noerror, and dd encounters read error when reading the block (let's size 100M), does dd just skip 100M block and reads the next block without writing something (dd conv=sync,noerror writes zeros to 100M of output - so what about this case?)? And if is hash of original hard disk and output file different if done without conv=sync,noerror? Or is this only when read error occurred?

• Why does running this program on 11.10 give a 'GLIBC_2.15 not found' error?

  - by RafLance

  I am trying to install Absinthe 2.0.4 on Ubuntu 11.10 on a netbook. When I try to run the install file, this keeps on happening: rafael@RafLaptop:~/Desktop/absinthe-linux-2.0.4$ ./absinthe.x86 ./absinthe.x86: /lib/i386-linux-gnu/libc.so.6: version `GLIBC_2.15' not found (required by ./absinthe.x86) Do I need to upgrade GLIBC? If so, how do I do that? Since I'm on a netbook I can't use a LiveCD so I wanted to know if there was a way I could fix this issue without reinstalling my whole OS. Any explanations about what GLIBC is exactly would be great too since this is a learning experience for me. I know that GLIBC is a part of libc.so.6 and so I tried to run sudo apt-get install libc.so.6 but was told that it was up to date. But GLIBC isn't? I hope this articulates my problem well, if there are any pieces of missing info or questions to clarity my question, please let me know! ~-~ EDIT/UPDATE: So after some help on the AskUbuntu chat room from user izx, I have gathered the following information/understanding: -I need to run this program with Ubuntu 12.04 or recompile it from source -Upgrading libc on Oneiric to 2.15 while possible, is not an easy task and is not officially supported.

• GNOME session not starting after filesystem corruption

  - by user3215

  I'm running Ubuntu 9.10 desktop edition. Suddenly today /home became corrupted and I was prompted to run fsck manually. I ran fsck -y /home and rebooted the system. The system booted but I got no GUI interface (GNOME session) but a black screen with a user prompt instead. Any tricks here to start my system normally? Any help is greatly appreciated.

• Word document has very strange "hidden" formating after converting from PDF to .docx

  - by Celeritas

  I have a PDF document with my resume which I need to edit. I used this service to convert it to doc. I opened it in Word 2010 and saved it as .docx. There are some bizzare problems where there's empty space and if you try to delete it text gets shifted into vertical columns. How can I fix this? I'm afraid this document has a lot of private information and I can't just fill in dummy text, then the formatting gets even more messed up :/ Otherwise I'd post screen shots.

• Chrome developer tools - network panel gaps

  - by Chris Nicholson

  In the Chrome developer tools, under the network tab, I'm curious to know what is happening during the gaps. If you look at my image below, I have highlighted in orange the areas where these gaps exist. Where I'm able to load a lot of my page from cache it's a shame these large gaps occur as they make up most of my page load time. What exactly is happening in this time? EDIT Okay I found this answer which essentially sums up my question, so a different question: does anyone know a good method to reduce the length of these gaps? Presumably (albeit rather extreme) if I loaded all my CSS on the page there wouldn't be a delay after loading the CSS file before the images were loaded.

• How to properly store dotfiles in a centralized git repository

  - by asmeurer

  I'd like to put all my dotfiles (like .profile, .gitconfig, etc.) in a central git repository, so I can more easily keep track of the changes. I did this, but I would like to know how to properly handle keeping them in sync with the actual ones in ~/. I thought that you could just hard link the two using ln, but this does not seem to work as I expected, i.e., if I edit one file, the other does not change. Maybe I misused the ln command, or else I misunderstand how hard links work. How do people usually do this? Judging by GitHub, it's a pretty popular thing to do, so surely there's a seamless way to do it that someone has come up with. By the way, I'm on Mac OS X 10.6.

• Work around for yahoo mail slowness (using 100% cpu)

  My yahoo mail is very slow sometimes. When it is, I notice that IE8 is using 100% cpu. Using sysinternals process explorer I discovered the thread using all the cpu in IE8 has Flash in the stackwalk. I upgraded flash from 9 to 10, but the problem persists. I'm about to edit hosts to block the flash content by redirecting the yahoo and ad click dns entries. Is there some easier way to get flash to behave? The fix for the long run will be switching to gmail.

• Western Digital Mybook is creating folders I didn't create

  - by Rogue

  I have a WD MyBook which has been creating empty folders with a long string of numbers and alphabets and some shorter ones with just some numbers with a 0kb file in it Some of these can be deleted but some just stay put. It's irritating to find new ones everyday and now i have a collection of them which don't delete is there any way to delete these ? Edit: I have scanned the drive using Antivirus and AntiMalware Software so i don't think it would have a virus One solution is copying all the matter elsewhere and formatting the hard disk but there is not guarantee that these folders wont reappear.
