• Programming Language for RF scanner [closed]

  - by Sid

  I am a Software Developer mostly on Windows System. I have been tasked to create an App Program for an RF Barcode Scanner. Which I don't have any experience in this kind of software. I am open to learn new Programming Languages to develop the software for this barcode scanner. From which I see on our meeting. It uses Windows or Windows Mobile as OS. Can someone direct me to a tut site or just tell me what language I should use? Requirements is mostly, Log In, UI Entry of Details + Barcode, Process Button. Connection To SQL Server via Wifi Access Point to call the procedure afterwards. I am not developing a Barcode scanner, I am developing a UI Software like a Mobile App. I tried to google but I dont know what exact keywords I should search for. My question is, what PL is mostly used to develop this kind of softwares.

• Windows 7 professional won't boot after installing ubuntu 11.10 alongside

  - by Piman3.14

  I can't boot into windows 7 professional after installing ubuntu 11.10 alongside windows as a dual boot. Windows starts to boot but then it stops during start up and "crashes". I do not have an installation or repair disc and windows is not registered as I built the computer in a class. Please help anybody who is familiar with ubuntu. Optimally I would like to just uninstall ubuntu altogether as GRUB scares me a little and Ubuntu isn't as good as windows 7 and "Bleeped" stuff up. I tried google and nothing that great came up and also I can't find a phone # to contact ubuntu/linux. :-( Specs: OS: Windows 7 professional x64, Ubuntu unity 11.10; CPU: Intel Celeron 2.6 GHz; 2 GB of RAM; Built in september or october 2011. Desktop Homebuilt PC.

• Why does Ubuntu Freezes on ASUS K42DY laptop with RADEON HD6470M Graphics Card?

  - by ix3

  Hi,I have an ASUS K42DY laptop with AMD Phenom II x2, 8 GB Ram , 500 GB Hard Drive and has a didicated ATI RADEON HD 6470M Graphics Card and I'm running Ubuntu 12.04 LTS 64bit on it. I have installed GNOME 3 and also followed this Make Ubuntu look like Mac OS X. I have also installed apps from the software center, getdeb & playdeb all of which worked fine. However, I noticed that Ubuntu freezes after inactivity let's say 1-3hrs. I have already set power setting to never standby or hibernate. This is completely annoying because all I can do is log-out via ctrl+alt+del or manually shut down and reboot my laptop. What should I do? By the way, this happens on all shells Unity, Gnome (even with the basic) and Cairo Dock.I set Swap Space at 8GB during installation. Any help will be appreciated. Thanks!

• Grub rescue doesn't allow me to boot from LIVE CD/USB

  - by Thameem

  I used to have Windows Vista & Ubuntu 12.04 on dual boot. Accidentally, I deleted the Linux partition and landed on Grub rescue on the next boot. The tricky thing for me here is I have been trying to boot through LIVE CD/USB of the ubunutu version, other linux versions but in vain. What happens is, it appears as if it reads the CD/DVD drive or the USB flashes for a while when trying to boot through LIVE versions but the Grub rescue appears after a while. The only option I could think here is to remove the hard disk and connect to the other laptop I have through USB and reinstall a fresh OS. Please suggest me a way to boot through the DVD/USB again. My laptop is Sony VAIO CR32 series.Thanks.

• ASUS VX-6 Laptop Wireless not connecting

  - by user2152790

  Someone posted a script a couple days ago, here is my output.Pastebin I can see wifi SSIDs in network, but cannot connect to mine. The only time wifi worked on 13.10 was in the Live CD, but wifi stopped working as soon as install process started. Did below but made no difference. sudo apt-get install bcmwl-kernel-source sudo modprobe -rv brcmsmac sudo modprobe -v wl What I do next? I tried Software&Updates and it showed 1 proprietary driver in use. This sounds like a WPA/WPA2 issue? Wifi works when I tried Zorin OS 7.1, wifi always worked in windows 7.

• Virtualbox Kernel driver not installed

  - by Cyndi

  I tried to use my Virtual Box and this is the error I received - (I just updated to the new Ubuntu also) and I am VERY new at this Linux OS :) Kernel driver not installed (rc=-1908) The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Please reinstall the kernel module by executing '/etc/init.d/vboxdrv setup' as root. Users of Ubuntu, Fedora or Mandriva should install the DKMS package first. This package keeps track of Linux kernel changes and recompiles the vboxdrv kernel module if necessary.

• Ubuntu 14.04 Fatal Exception

  - by user286534

  I use Ubuntu 14.04, 64-bit. I installed Virtualbox and was testing another Linux OS (Deepin). My system froze and I could not get to a TTY session to reboot. I had to do a hard restart and when Ubuntu restarted I got various error codes one of which was "kernel panic - fatal exception in interrupt" Booting to Advance mode and attempting repairs did not work (fsck, grub repair, etc) I reinstalled Ubuntu and chose the option to keep my files intact. I can now access my system but many programs I have installed do not work. My question is; I have a Deja-Dup backup (but only of my Home directory), is it better to restore my backup files or do I have to reinstall all of my programs? The weird thing is, the programs I verified using the Software Center to see if they were installed are checked as installed, but won't appear in Dash.

• Momentary freezes about every 60 seconds

  - by Barafu Albino

  I have just switched from OpenSuse to Ubuntu (the only reason is poor repositories - I got tired of installing everything from tar-balls). OpenSuse KDE worked flawlessly. Off-topic OS 7 does too. However, Ubuntu 13.04 after all updates keeps freezing about every minute. The time differs between occasions. It halts just for a fraction of a second, too quick to notice, but music crackles, and compressed video looses its tracks and covers with errors until a scenecut. I don't know what is responsible, the logs are clear. Tried to: change audio card, switched to Nvidia drivers and back, paused all unneeded daemons. Didn't help much. Any ideas where to look? I am experienced in Linux, just new in Ubuntu.

• Microsoft annonce une vulnérabilité dans Windows 7 et Windows Server 2008 R2 versions 64 bits qui to

  Microsoft met en garde contre une vulnérabilité de Windows 7 Et Windows Server 2008 R2 : elle touche Aero et les versions 64 bits Dans un bulletin de sécurité, Microsoft met en garde les utilisateurs de Windows 7 et de Windows Server 2008 R2 contre une vulnérabilité récemment découverte dans les versions 64 bits de ces deux OS. La vulnérabilité pourrait permettre l'exécution d'un code arbitraire. Le « pourrait » est important car la dangerosité de la faille semble être assez faible. Néanmoins, deux précautions valent mieux qu'une et Microsoft continue à jour la carte de la transparence (cf. ci-dessous "Lire aussi"). On apprend dans le bulletin de sé...

  - by user71468

  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. I don't get to see login screen. This worked well last week, before installing updates. 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.

• 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).

• Limitation of high level languages? [closed]

  - by user1705796

  My question may look bit philosophical and nonsense! But I need to know kind of instructions those are not well suitable in high level languages even in c? Or rarely use in the development of software? Like read/write content of CPU registers may useful in debugging programs. And access to cache memory required when developing OS (maybe I am wrong at this point). Is this kind of instruction available languages like Java, Python, C? I also have a second question: And Why all high level languages not having same uniform syntax; at-least same standard library interface name? In python there is and. Or operator is almost same as && and ||. I think Python is developed after C but space indentation is compulsory in Python. Why Python does not use brackets {}. I already know this question going to be highly down-voted.

• How to avoid problems when installing Ubuntu and Windows 7 in dual-boot?

  - by BlaXpirit

  I want to try out Ubuntu (and hopefully choose it as my primary OS). After looking at many versions of it in VirtualBox and from Live CD, I've finally decided to install it. So I defragmented and shrinked one of the partitions to make room for Ubuntu. My current setup (after shrinking the D: partition): [·100 MB·] [······250000 MB······] [·······600000 MB·······] [··100000 MB···] Reserved Windows 7 system (C:) Data (D:) Free space NTFS NTFS NTFS (for Ubuntu) The Internet (including AskUbuntu) is full of scary stories about Windows not loading after installation of Ubuntu, something about installing GRUB to a wrong partition, etc. As I am a newbie to Linux and Ubuntu, it is very easy for me to do something wrong. Please mention the problems that may appear and explain how to avoid them. Ubuntu version that will be installed: 10.10 Desktop amd64 Please note that I have installed Windows 7 about a year ago, so I have much to lose if something goes wrong. I want to be very careful because there is no way for me to backup all the data.
