• A Single wireless network is not showing up in Ubuntu that used too, and other devices have no issue finding or connecting to it

  - by Kit Sunde

  Up until about a week ago I could connect to my wireless, but now I suddenly can't. Every other wireless in the area show up in the network manager. My kindle can connect to it, my friend can connect to it (in windows) without having connected to it before. My other netbook (Samsung NC10) can connect to it, but my other Samsung N150 now cannot even see it. I have tried deleting the old auto entry for it in the network manager Tried disabling and enabling both the networking and the wireless through the network indicator. Disabled the networking through the hardware shortkut key thing [fn] + [F9] Attempting to connect to it as if it was a hidden network. I'm at a loss, how would I go about debugging and unborking my computer?

• Resolution problems

  - by tampe125

  i'm having some troubles with screen resolution. First of all, i'm using a Lenovo Thinkpad E520, with BackTrack 5 R2 installed. As far as I know, BT is based on Ubuntu 3.2, so I hope this is the right place to ask for help. My natural resolution is 1366x768, but I'm stuck with 1024x768. This is my hardware: lspci | grep VGA 00:02.0 VGA compatible controller: Interl Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) How can I fix that? Is there a ready-to-use driver or I have to compile that from source? At least, is there a solution, at all? :(

• How to handle situation of programmer stealing credit for your project [on hold]

  - by shorecc

  There is a coworker who has stolen credit for my work. I created a system that will show live statuses of printing machines throughout the plant. There was one glitch in it so the coworker made an improvement and then re-wrote the entire system (copying 90% of my code, yet he added a new piece of hardware then took over the project). Now he asks me programming questions from time to time. I don't mind teaching coworkers how to program, but since he has stolen my ideas and credit in the past I am reluctant to teach him all I know. Today he asks me for a particularly challenging algorithm for this system. His code now looks exactly like the way I would program! How would you handle the situation? How can I decline helping him without appearing to not being a team player?

• I need advice on how to debug a cluster

  - by alcor

  I'm the only developer of a complex critical software system, written in Visual C++ 2005. It's deployed on a classical Microsoft cluster scenario (active/passive), that has Windows Server 2003 R2. If a server A goes down, the other one (B) starts and take the ownership of its duties. You have to know that: both servers have the same Microsoft patches/fixes, same hardware, same everything. both servers use the same memory storage (a RAID-6 through fiber channel). this software has a main module who launch the peripheral modules. if a peripheral module crashes, the main module restarts it. When I switch the application in one of the two servers (let's say the B server) two of the peripheral modules of the main applications just started to crash apparently without reason about 2 seconds after the start of the peripheral module. What could I do to analyze/inspect/resolve this weird situation?

• Getting Started with 12.04 LTS Problems

  - by mark

  Okay previously I used ubuntu 10.04 in Desktops and Loved it! I bought a newer Toshiba Satellite with an i7 CPU, 8GB Ram, 1TB HD, first thing I tried to do was install Ubuntu 9 on it then I found out it was no longer Supported. (I gave my 10.04 disk away) So I tried installing Windows 7 and experienced SO MANY problems, I am going back to try 12.04. Starting all over again. After installing 12.04 Wireless was Detected yet said it was Disabled by a Hardware Switch. Went read through the Message Boards found Solution which was Sudo rf Kill All. Okay all excited I would finally get my Ubuntu to finally work I rushed back to my laptop from the internet cafe, and went looking for the TERMINAL input on my Ubuntu 12.04, and I cannot find the Terminal. If I can't find the TERMINAL how Can I enter any Sudo Stuff? So I guess the first question is Where is the Terminal Located in 12.04? Thank you.

• Wait random number of minutes

  - by TiborKaraszi

  Why on earth would you want to do that? you ask. Say you have a job that is scheduled to start at the same time over a number of servers. This might be because you have an SQL Server Master/Target server environment (MSX/TSX) or you quite simply script a job and execute that script on several servers. You probably want to spread the load on your SAN and virtual machine host a bit. This is the exact reason I use this procedure. I frequently use MSX servers and I usually add a job step (executing this...(read more)

• What is the preferred/recommend way of running two version of ubuntu side by side

  - by GreyGeek

  I am running 14.04, but I need to run some corporate software/scripts that have been specifically designed for 12.04. I am aware of virtual box/vmware for full virtualization but I am looking for something more lightweight (on my windows machine both come at a significant cost in battery life) closer to os virtualization level. Ideally, I would like something like windows 7/8 compatibility mode: the ability to run a program as if I were on 12.04. Does Ubuntu/Linux have such mechanism? What is the preferred way of running programs/scripts designed for an older version of Ubuntu?

• As a minor, how can I make programming profitable? [closed]

  - by lesderid

  Possible Duplicate: Can I be “too young” to get a programming job? I’m 15 and I want to Freelance I've always loved programming. I started when I was about 8 with making some silly WinForms applications in VB.Net that basically did nothing. Now, I'm 15 and I would say I'm quite good C# and I'm reading through Jon Skeet's C# In Depth. I also have some experience with VB, C++ and Assembler (mostly reverse engineering). I really love coding, which got me wondering about college, what I can study to get into the software business. However, I would like to earn some money now, so I can spend it on better hardware, on development tools or on other hobbies. This is hard because I don't have any work experience nor have I done any programming-related studies. It's also not legal for me to do any freelancing jobs as I'm under the age of 18. How can I use my current experience at my age to earn some money?

• Ubuntu 12.04 x64 - Very slow response and sluggishness

  - by Murphy1138

  Recently updated to 12.04 x64 on my AMD HEX core 4GB system, over the last few days I feel that the overall system is sluggish/laggy , for instance hitting the dash button, the dash opens but the recent activity of files/videos etc is incredibly slow to populate, like wise in Nautilus and browsing my media, the file names are showing up but it takes an age to populate the "thumb" of the video, If I go into Gnome-shell the shell response is a little faster but again clicking on applications there is still a noticeable pause. I have the latest Nvidia Drivers loaded and I have very fast SATA drives, if I reboot into windows 7 the system is so much quicker in its response, I only use windows for games and Ubuntu is my main OS. 10.04/10.10/11.04 was Super quick and this was when the system still had a Duel Core Chip and a worse Nvidia card, 11.10 was pretty snappy, but 12.04 just feels bloated on each system I have installed it on. My hardware is more than up to the task so has anyone got any commands i can run to help diagnose the issue? Anyone else got the same problems? Thanks Murph

• How to use NVIDIA GeForce M310 on Ubuntu 12.10 running as guest in Virtualbox?

  - by huub

  Last couple of weeks played around with Ubuntu 12.10. This is running as a guest on Virtualbox hosted at Windows 7. There have been some challenges with the Unity 3D stuff. Particular due to not supporting X11 release 1.13 till very recently. Since today we are able to download Virtualbox version 4.2.2 which has through guest additions also support for X11 release 1.13. SO far great work everybody. Since Unity now only runs in 3D mode it would be nice to access the graphics card directly from Virtualbox. lshw -c display shows: VGA compatible controller; product: VirtualBox Graphics Adapter. QUESTION: how to get the 3D and other graphics directly supported by the hardware ie Nvidia GeForce M310

• Missing Firefox app icon

  - by frozenkoi

  I'm using Ubuntu 11.04 (upgraded from LTS 10.04) and Firefox (version 11) doesn't show it's icon in the Window List panel, in the Firefox window top left corner (system menu) nor when using ALT+TAB to switch applications. I'm using unity 2D since I'm running ubuntu as a guest in a VMWare virtual machine (Host is windows 7) Instead of the Firefox icon I get what appears to be a generic icon that looks like an app window in the window list and a black rectangle with a curl in the bottom right corner in the ALT+TAB window. How do I fix this so that the proper Firefox icon gets displayed? EDIT: Depending on the icon set chosen in the Appearence settings window sometimes I get the icon, sometimes I don't. When using Ubuntu classic none of the icon sets provide the icon for Firefox.

• Installing VMware Worstation/Player 8.0.4 on Ubuntu 12.10 fails to load with Unable to start services

  - by user106986

  I have been attempting to install this application for a few weeks without any success. I have installed and uninstalled the application and pathes with no change. I have even tried to load a VM in Virtualbox and install the application there to a base install of Ubuntu 12.10 and it still did not install. I have downloaded the patch and modified it to reflect the version of VMware Worstation and Player I am installing. I still receive the same error I saw in the first attempt to install the software. Which leads me to think that I am missing something. The error is: Unable to start services. See log file /tmp/vmware-root/modconfig-7674.log for details. I have the output of the log file if that will help. According to the dialogue box Virtual Network Device and VMware Blocking Filesystem fail to either load or execute. Any help would be greatly appreciated.

• How is Sencha Touch performing on Android in practice?

  - by user14557

  I'm just about to start a project using Sencha Touch, and just done some minor testing on my HTC desire device. All tutorial videos at Vimeo seems to be using an iPhone emulator running on a Mac. Im not sure how fast this emulator is compared to a real iPhone device or even an real Android device, but from what i have experienced, it seems that my HTC desire is not performing that nicly as this emulator. All animations (sliding, fading, etc) seems abit laggy. You can easily notice that the FPS is much less than on the Vimeo videos. HTC desire is a relativly new and modern Android 2.2 phone, running with decent hardware, so im wondering if Sencha Touch is "ready" for the Android platform. Anybody with practical experience with Android and Sencha Touch ?
