• How to update the USB Ubuntu (ISO) with new software

  - by nakata

  I have Peppermint (based on Ubuntu) running of USB. Its bascially an ISO image that loads using Grub4Dos. Problem is that I each time I load Ubuntu - and want to use i.e. teamviewer or Firefox...I have to install it on the running live system. Since its running from a ISO image...a reboot means the software is gone. I can edit/open the ISO image using WinImage (on XP) - would you know how I can add extra software into this ISO image so next time Ubuntu loads...the new software is on there? Is there some special repositary director where I should copy the software files into and recreate the ISO image? The directory structure of this iso image is along the lines of: .disk [BOOT] Casper dists install isolinux pool preseed Appreciate your help with this. The software I am really interested in installing is the plugin for LogMeIn (for which I may need Firefox...thus I need Firefox installation) and Teamviewer. Thanks Nakata

• CreateDXGIFactory Doesn't Let Program Exit

  - by smoth190

  I'm using CreateDXGIFactory to get the graphics adapters and display modes. When I call it, it works fine and I get all the data. However, when I exit my program, the main Win32 thread exits, but something stays open because it keeps debugging. Does CreateDXGIFactory create an extra thread and I'm not closing it? I don't understand. The only thing I would suspect is that in the documentation it says it doesn't work if it's called from DllMain. It is in a DLL, but it's not called from DllMain. And it doesn't fail, either. I'm using DirectX 11.

• Can't load Wordpress static files on home network

  - by Tosho

  I've just installed Wordpress 3.5 on my laptop (LAMP on Ubuntu 12.10) and when I'm trying to access the site from my phone but it doesn't load static files (css and images). I tried with Opera Mobile Emulator on my laptop and it works perfectly. I also have another Drupal site on my localhost which I can load from my phone without any issues. Both directories have chmod 777 permissions. What can cause that? Just tried to open the site from my sister's laptop but it except static file I can't access any post or page.

• How do I install the latest NVIDIA drivers from the .run file?

  - by Shahe Tajiryan

  This is what I am trying to do. I downloaded the latest driver for my VGA from http://www.nvidia.com. The installation needs the X11 to be shut down, so I log out of my account, then press Ctrl+Alt+F1, then log in with my username and password, then run the command sh NVIDIA-Linux-x86_64-285.05.09.run in every possible way, I have even tried CHMODing the package with 777 permissions, but still I'm getting the sh: can't open NVIDIA-Linux-x86_64-285.05.09.run error. Any help would be greatly appreciated.

• Low display resolution under Ubuntu 12.04

  - by Chinouk

  I had some problem after installing new drivers for Nvidia. After having followed the instructions answered to this question, I now only have the Nouveau open-source driver. I can have access to my desktop, but I'm stuck with a 640x480 (4:3) resolution. No other resolution is proposed in the dropdown list of the "Displays" utility. I tried installing the two Nvidia drivers suggested in the "Additional Drivers" utility, but each one broke my display again. Now that I have reverted back to Nouveau again, what should I do to get a higher resolution ?

• Trouble with printer canon lbp2900-Ubuntu 14.04

  - by user288922

  I use Ubuntu 14.04. I installed the printer Canon LBP2900 following the guide and did all steps and now the printer works. I added CCPD in Startup Application (with command: sudo /etc/init.d/ccpd start). But after I log out or restart my pc, the printer can't print until I have to open terminal and run sudo /etc/init.d/ccpd restart && sudo /etc/init.d/cups restart. Once more, after restarting my pc I’ve just only printed 1 job (of course it can't print), and I run sudo /etc/init.d/ccpd restart && sudo /etc/init.d/cups restart, the printer will work but it prints the same job three times.

• Problem installing libva (VAAPI), vainfo fails

  - by satuon

  I'm following a wiki on how to make VLC use the GPU in the Core i3 integrated graphics chipset, but I'm stuck at one of the first steps, installing VAAPI.

• Do any database "styles" use discrete files for their tables?

  - by Brad

  I've been talking to some people at work who believe some versions of a database store their data in discrete tables. That is to say you might open up a folder and see one file for each table in the database then several other supporting files. They do not have a lot of experience with databases but I have only been working with them for a little over a half year so I am not a canonical source of info either. I've been touting the benefits of SQL Server over Access (and before this, Access over Excel. Great strides have been made :) ). But, other people were of the impression that the/one of the the benefit(s) of using SQL Server over Access was that all the data was not consolidated down into one file. Yet, SQL Server packs everything into a single .mdf file (plus the log file). My question is, is there an RDBMS which holds it's data in multiple discrete files instead of one master file? And if the answer is yes, why do it one way over the other?

• What framework for text rating site?

  - by problemofficer

  I want to start a "rate my"-style site. The rated objects are mostly texts. I want it to be rather simple. Features I need: object rating (thumb up, thumb down) object comments object tags related object presentation based on tags user authentication and management private message system sanity checks for text inputs (i.e. prevention of code injections) cache open source runs on GNU/Linux I would gladly take something that is tailored for my scenario but a generic framework would be fine too. I simply don't want to write stuff like user authentication that is been written a million times and risking security flaws. Programming language is irrelevant but python/php preferred.

• How do I secure a Tomcat installation?

  - by spangeman

  I have installed tomcat on my Ubuntu Home 11.10 system and can successfully access the test page online after port forwarding on 8080 within my router. I have not made any other changes to the router, Ubuntu or the tomcat install, everything else has remained standard. I intend on using this to play around with Java Servlets and basic web development for my own personal use. What steps, if any, would you suggest I take to ensure this is secure? Should I change anything within the Tomcat configuration? This seemed like a good idea to limit access - http://www.seankilleen.com/2010/09/how-to-allow-only-specific-ip-addresses_30.html But I am open to any other recommendations.

• Is there a way to mirror directory changes in Terminator?

  - by Kasisnu

  I'm on Ubuntu 12.04 and am using Terminator as my primary terminal. I like it because it lets me keep a python interpreter and bash terminal open at the same time, in the same view. What is annoying is that I end up moving between directories A LOT, and then I have to do it twice. Is there a way to set up a terminator configuration to do that? To have terminator mirror directory changes. I'm guessing I'm not the only one that finds that frustrating!

• Ubuntu 14.04 LTS AMD64 randomly uninstals packages / applications

  - by Jacob Lindeen

  I am having a strange issue. Occasionally when installing new packages, I will get a system crash notification which I will report. The environment then becomes unstable, unity crashes and all open windows, loose title bars, and the main launcher shuts down. I usually have to run the command unity --replace to restore functionality, but ultimately end up having to reboot. Upon booting back up I find all of my user-installed packages are gone and I have to reinstall them via apt. Please tell me someone else is having this issue, because this is the second system and third install I have had this issue on.

• Hosting my own SVN repositories

  - by TheAdamGaskins

  I've been experimenting with Google Code and Sourceforge and the like, and am happy with what I've found. The main problem with them, is that you have to have your project be open source to use them, so anybody can edit them. So... is there some way I can have my own svn repositories on my own server? I have FTP access, cpanel, and all that. If it helps any: Operating system Linux cPanel Version 11.26.20 Architecture x86_64 MySQL version 5.0.91-community-log Apache version 2.2.13 PHP version 5.2.11 cPanel Pro 1.0 (RC1)

• Good places for starting to learn Lua scripting [closed]

  - by Cascalho

  I want to start learning to script in lua for game development. I could start with the official Lua tutorials, but I would rather study scripts that were written specifically for games and learn the syntax from there as I believe this is faster and more related to what I want. Can you recommend tutorials in video or text that are very detailed in explaining the code? Or some open source game with heavily commented code? What I want is something detailed that walks me through it, so I start understanding both the syntax and how each piece relate to each other, like "First of all, install this, this and that." "So, here we are defining a new function that will make the player jump." "This is the main script that calls the other ones. It defines these variables." "This function tests if the player is alive."

• Ruby using the Gosu framework: why it runs slow first time?

  - by Omega

  I'm creating a Ruby game using the Gosu framework. All good. Sometimes, when I run the game, it has some kind of slow startup, and probably it will be rather slow during the whole game. So I close it and... open it again. It is very likely that it will startup quickly and the whole game will run smoothly and fast. Why is that? What is this phenomenon? Is it faster because of some cache stored or whatever since the first run? (But why would cache be stored? If the app dies, I would expect no references at all etc...) Ruby, Windows 7.

• Facing quality issues

  - by juststartedmycareer

  A workforce management software has complex GUI (for example values in a page depends on the status (closed or open) of other pages). Only latest and near past development has test coverage. During our last release, we received lots of bugs from customer in-spite of 2 weeks of testing Sprint . We don't have dedicated test team. The developers does the unit test & User acceptance test. Every day triggers automated regression test. I am afraid the developers are not testing the entire workflow because its time consuming also not able to automate it because of its complexity. Any suggestions ?. The legacy code (15 yrs development) has less code coverage. How can I improve quality ? Note: Now not possible to hire testers to have independent test team!!
