• How do you diagnose constant crashing issues?

  - by P102

  My recent installation 10.10 on my laptop keeps freezing/crashing on start-up after working perfectly for one day. The system just freezes, like a screnshot, and a restart is required. It happens directly after login or just as any application is selected. Nothing new has been installed. I have just moved from XP so I would be very grateful if some one could please explain to me, as simply as possible, how to do the following... How to diagnose the problem so it can be fixed, remember it may have to be before the log in. all help is greatly appreciated.

• Good site building for little kids [closed]

  - by guy mograbi

  I am teaching kids to write 3d games with Unity. Now I want to publish their games online along with some other stuff. I don't want to teach them HTML, CSS etc.. I don't mind buying the domain (after a bad experience with "TK" domains I concluded buying one is better), so all I need it hosting and possibly with a builder with a nice interface. Couldn't find one which seems to be the right fit. Can you recommend of anyone? Static HTML hosting will do, but I prefer PHP support and DB just in case we will need to implement a login mechanism.

• What to use for an event listing site? [on hold]

  - by Vykintas

  I have a site which lets users buy & sell tickets, but it's built on wordpress & buddypress. So it's very heavy and messy. I would like to re-do the whole site on something lighter, cleaner and solid. The main functionality for user would have to be as follows: Register or login via Facebook. Create events and sell tickets to them. See ticket sales statistics Upload photos and associate those with events. Buy event tickets, print pdf ticket. Comment, favourite and like events. What would be your suggestions? PHP framework? CMS? CMF? I must say that I'm a front-end dev so building a system from scratch on my own would take a while. I'd be interested more in a "skeleton" app solution or something similar.

• Free web mangement control panel

  - by Thorn007

  Hey guys I need some help. I will also apologize for not being able to be more specific. I'm looking for a specific web admin panel. that uses a login page via port 2222 or 4444. This is not vanilla forum or any forum. So the only way I know how to make this a legit question is to ask what "free" control panels do you use to manage your web sites. This means files and domains. Why do you use it? Where is it located?

• How to generate `AllowDeactivateGrabs` in command line ?

  - by boffin

  I am using XFCE-Ubuntu and do a lot of my development work there. In my case, when I sometimes use Xilinx ISE, the mouse cursor hangs as a Grab pointer and then stops responding. The entire X environment becomes unusable and I have to kill it and restart. This is becoming a serious annoyance. I saw this bug: AllowDeactivateGrabs is broken I see that sending AllowDeactivateGrabs in command line can kill the Grab. In my case, I am doing this on a remote server, so it is the application in the remote server (over X2GO) getting messed up. I am able to login in command line and kill X. Is there a way to generate AllowDeactivateGrabs in command line ? So I dont mess up my other applications and potentially lose data.

• What are general guidelines and advices to estimate how much you should charge for a project, being a novice freelancer?

  - by Dokkat

  I am an experienced programmer but completely new to the market. Someone wants me to do a project for them, but I do not know how much it is worth. What are general guidelines/advices for finding what a project is worth on the market? If I can ask here about this particular one, it is a HTML5 site with a login/register form and a video player that has to play a lecture video and powerpoint slides synchronized. They'll give me the video, the audio the powerpoints. I should also do some editting on the video before.

• Update to 13.10 without GUI access

  - by Tom

  After upgrading 13.04 with the latest patches, I'm getting some really weird problems -- namely, logging in at the GUI just dumps me back at the GUI login screen. I can, however, get command line access from Ctrl-Alt-F1, and remotely via SSH. Given that I was doing these updates to step to 13.10, I figure I might as well continue the process, and then deal with the fallout once I get there. However, how can this be achieved with only the command line, and no X available? The only method I've found thus far is to run 'update-manager', which does not appear to have a CLI mode (and will not start without access to X). What's the solution? Thanks!

• Is there a way to develop desktop software using PHP?

  - by user1492018

  I have to develop a real estate marketing CRM software for my client - where the application is installed on desktop but can also be accessed from web. 2 reasons why they want the application to run from desktop : So that it can work with/without internet connection They don't want their complete data to be online They want to access few of the data like property listing & inquiries (managed from desktop application) from their website through secure login & password. The data that is entered in desktop application should be automatically synchronized with the website application. I was wondering if there is a way to develop this kind of software using PHP & MySQL. If yes, it will be great if anyone can provide me the referral link.Else please suggest, which language should I use.

• Who created that user?

  - by AaronBertrand

  Twitter has provided some great fodder for blog content lately. And twice this week, I've found an excuse to take advantage of the default trace. Tonight @meltondba asked: I'm trying to find who created a user act in a DB It is true, SQL Server doesn't really keep track of who created objects, such as user accounts in a database. You can get some of this information from the default trace, though, since it tracks EventClass 109 (Audit Add DB User). If you run this code: USE [master] ; GO CREATE LOGIN...(read more)

• Returning status code where one of many errors could have occured

  - by yttriuszzerbus

  I'm developing a PHP login component which includes functions to manipulate the User object, such as $User->changePassword(string $old, string $new) What I need some advice with is how to return a status, as the function can either succeed (no further information needs to be given) or fail (and the calling code needs to know why, for example incorrect password, database problem etc.) I've come up with the following ideas: Unix-style: return 0 on success, another code on failure. This doesn't seem particularly common in PHP and the language's type-coercion messes with this (a function returning FALSE on success?) This seems to be the best I can think of. Throw an exception on error. PHP's exception support is limited, and this will make life harder for anybody trying to use the functions. Return an array, containing a boolean for "success" or not, and a string or an int for "failure status" if applicable. None of these seem particularly appealing, does anyone have any advice or better ideas?

• Looking for open-source solutions for a knowledge sharing website

  - by Bundarr

  There is a need in my workplace to setup a knowledge sharing site, a place where users can discuss projects they are working share documentation ask questions I am looking for a open-source system that answers these needs, and that can be setup in a week, and requires only PHP and MySQL. I am a Wordpress fan and developer and could easily implement such a system in Wordpress, however this system needs to be very simple to use for the technically challenged. Without customization, Wordpress users would still need to login to the "back-end" to post. I like the Stackexchange (OSQA) format, but these do not allow for file uploading out of the box. I do not have experience with Buddy Press, would this be an alternative?

• Super slow and laggy?

  - by Mystogan

  I'm a native Windows user, running 7 Home Premium atm. In the past I installed Ubuntu 10 on my netbook I believe, but was a bit 'scared' by it. Anyways, I made a partition on my desktop pc, 100gb and installed Ubuntu 12.10 on it. It was pretty slow first thought it had to install updates or something, so I rebooted it. Now after the login it looks like everything freezes, I can move my mouse only ,but that's it! I can see my desktop and launcher, but the task bar doesn't display time and misc system info, only a black bar, I downloaded the android SDK pack and installed vlc media player before I rebooted. My computer info: - 1tb HDD - 8gb ddr3 ram - ATI Radeon 4890 videocard (1gb) - AMD Phenom 2 x4 black 3,2ghz CPU(64 bits) Thanks in advantage!

• Is the php method md5() secure? Can it be used for passwords? [migrated]

  - by awiebe

  So executing a php script causes the form values to be sent to the server, and then they are processed. If you want to store a password in your db than you want it to be a cryptographic hash(so your client side is secure, can you generate an md5 using php securely( without submitting the user:password pair in the clear), or is there an alternative standard method of doing this, without having the unecrypted pasword leaving the clients machine? Sorry if this is a stupid question I'm kind of new at this. I think this can be done somehow using https, and on that note if a site's login page does not use https, does that mean that while the databse storage is secure, the transportation is not?

• 12.10 Unity GUI Not Displaying

  - by lolajl

  I had 12.04 installed and had no problems at all, having had it setup on my Compaq Presario CQ62 for about 2 weeks (I'm new to Ubuntu and I had a spare laptop to experiment with). Last night, I installed 12.10 through the update manager. Now, I'm not seeing the Unity GUI if I select Default or Ubuntu, at all, just the Eclipse launcher which I had created sitting on the desktop. Even hitting the Windows key to bring up Dash doesn't work. But, when I select GNOME during login, I'm able to access everything in the GUI, including the menu folders for games, internet, system settings, etc. There was a couple error message saying that a system file wasn't loading properly but I forgot to write these down, and now these error messages aren't loading when I restart. Will I need to wipe clean and reinstall?

• FTP Changes file permisions

  - by AkBKukU

  I am trying to make changes to my website over ftp but when I save any files it changes the permissions and owner to my username. I can edit files in the same folder trough samba without changing the permissions. I really don't understand how the permissions for the /var/www folder work and I'm pulling my hair out trying to get it to work. I have recently made changes to the permissions of the /var/www directory (following this guide) so I could modify files in the www root. Right now I have the entire contents of /var/www set as -rwxrwxr-x 1 www-data www-data but when I change a file over ftp it becomes -rw------- 1 akbkuku akbkuku, akbkuku being my username. I am using vsftpd as the server, and I login with my normal user. How do I make it leave to permissions alone? At this point I'll even take a way yo reset all the permission back to stock and I'll just never modify files in the web root.

• How to pre-configure (configure defaults for new users) KDE?

  - by luxifer

  I'm trying to figure out how to configure KDE for new users. That is: setting up KDE and make these settings default for every user upon her first login. I know that there's /etc/skel but it's not working nicely because KDE writes user- and machine-specific stuff in its users configuration files and I want this to work for every user on every machine. Also modifying stuff in /usr/share seems wrong to me as well as stuff there could get overwritten by an update or - even worse - modifications there could make auto upgrade fail. So, is there a standard way of doing this? Thanks

• Ubuntu not booting after upgrade to 12.04 from 11.10

  - by ddd

  I upgraded to 12.04 from 11.10 today. After the upgrade, I did the usual reboot of the system and then Ubuntu hangs on Checking battery state..[OK]. I can login to terminal with Ctrl-Alt-F5 and I did startx but it hangs after displaying white images of the desktop icons..there is no menu or any top bar at all. I guess this problem has something to do with Xserver, but I cannot find xorg.conf on my system. How can I get around this problem? Also is there a way I can make a backup of my files through the command line, because the GUI is not showing up at all?

• How to fix: "The connection to the server was reset while the page was loading."?

  - by stupidity

  I have a 64-bit Ubuntu 12.04 installed. I used to login to a website (chess.com) but since a few days ago I get this message: The connection was reset The connection to the server was reset while the page was loading. The site could be temporarily unavailable or too busy. Try again in a few moments. If you are unable to load any pages, check your computer's network connection. If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web. This is the case in Firefox, and chrome. A friend of mine confirmed to me that the website is working fine and he could access it. And I can access many other websites and facing no issues except for this website. I tried switching the use TLS 1.0 option as suggested by someone but this didn't fix it. Can someone suggest a way to fix this issue?

• Linux (Ubuntu 12.10) starts up, but the main menu on the left side, and the pictograms at the upper right corner, do not show up

  - by user114220

  Linux OS (Ubuntu 12.10) starts up (user login, my personal picture of a beautiful Norwegian fjord-landscape fills the background), but the main menu on the left side, and the pictograms (battery state etc.) at the upper right corner of the screen, do not show up. This occurred yesterday quite suddenly after six or seven weeks working with Ubuntu 12.10. Then I started in recovery mode and performed a file system check (fsck) but that takes hours and finally a message ¨Sorry Ubuntu has experienced an internal error etc¨ appeared. How can I determine what has gone wrong and eventually, how can I solve it? So that I can work again using Ubuntu 12.10 (on a dual-boot system, Intel i7, ASUS P8P67 motherboard).

  This issue appeard after installing last week's updates from Update Manager. When waking up after suspend, the OS starts loading and it halts unexpectedly, before the load is complete.

Then I need to remove laptop's battery, wait a while, then plug it and start again (otherwise power button won't work). Is anybody else experiencing this behavior? I have an HP DV7 with an intel core i7.

• Settings messed up after crash

  - by ChocoDeveloper

  After an abrupt shutdown many settings were messed up: #1 Firefox was a mess. Bookmarks were gone, and I couldn't even add new ones. I had to reset firefox from safe mode and install all my addons and configure everything. This was a pain but is now solved. #2 The background in the login screen shows the one I chose with Ubuntu Tweak for a second, and then it puts back the default one. I tried changing it again with Ubuntu Tweak but it's still happening. #3 All my shortcuts in the sidebar were replaced by the default ones. I re-added them manually, also a pain. So how can I solve 2? And in case this happens again, is there a way to fix everything easy and fast?

• get_hosts script being ignored in LTSP setup on Ubuntu 12.04

  - by Shwetav

  We had a home-grown LTSP load-balancer based on LDM_SERVER and get_hosts in Ubuntu 10.04. After upgrading to Ubuntu 12.04, everything worked fine except that get_hosts is being ignored completely. If we put space delimited list of servers as LDM_SERVER in lts.conf, users can choose a server during login and things work fine. Tried both locations below without any luck so far: 1. /var/lib/tftpboot/ltsp/i386/get_hosts 2. /opt/ltsp/i386/etc/get_hosts Any pointers would be greatly appreciated.
