• Can't find partition tab in disk utility osX ver. 10.6.8

  - by John W

  I just got a used Mac Book Pro. I created a new admin account and deleted the old one as well as one other user. This is an older late 2007 MBP... the osX upgrade to 10.6.8 was just performed. My Macintosh HD is showing up as Partition 2. I ran disk utility (not from install disk), but there was no partition tab. I have a 160GB drive with only 53GB of space left on it. Since I am the only user and have no files on the laptop yet, I don't understand why there is so little space left. Surely the OS can't use up over 100GB. I wanted to run disk utility to see if there were any recovery partitions or other partition left over from the previous owner that could be erased to make room for expanding the main partition. Unfortunately, there is no partition tab in disk utility. The documentation I have found on line states that this version of osX includes that utility. The osX disks I have are for an older version so I wasn't sure if they would be of any use in solving this problem. Also, I was afraid if using the disks, would I lose the little bit of data/apps that I have assembled. I would rather not do a fresh install and have to do all the updates again to achieve this. The previous owner had some apps that I don't want to lose as I would have to pay handsomely to get them back. Simply, if all the previous users data is backed up on here after deleting user is still taking up space on a recovery partition (that I can't see)... I need to locate it erase it and expand the primary partition to re-aquire disk space for my files. I am new to Mac, so please be as descriptive as possible. Thanks.

• Major problem with Nvidia drivers

  - by user38580

  Since I decided to use Ubuntu -yesterday- I've been struggling with the drivers. It isn't recognizing my optical disc drive nor my video card, a Nvidia 8500gt. For the matter, here's how I "successfully" installed the .run driver downloaded from Nvidia's website: The terminal wouldn't let me start the installation because the X server had to be shutdown, so I pressed Ctrl+Alt+F1 Then, I used: sudo service lightdm stop cd /(directory where the nvidiaupdate.run was) chmod +x nvidiaupdate.run sudo ./nvidiaupdate.run The installation began and got completed, but unfortunately it crashed Ubuntu's UI, invalidating the OS for me. All that would appear was a DOS-like screen with reports. I'm new to Linux, so I really would appreciate any help given. For now, I'm sticking to the additional drivers, but even with it Ubuntu doesn't show my video card in the informations of the system. Forgive my bad English.

• Determining an application's dependencies

  - by gpuguy

  I have developed an application using Windows Forms in C++ (IDE MS VC++ 2010). Some parts of the application also use MFC, and OpenCV. I want to send the application to my cleint for interim testing on his own machine. I have not developed any installer for the application, so I will be sending him an .EXE file. I want the client to not face any difficulties in replicating the environment, and therefore not lose any time. Can somebody suggest me what software (such as MS VC++ Runtime, .NET Framework, Windows SDK, etc.) should be installed on the client's machine for successfull testing of the application? Note: The OS (Windows 7) and hardware are exactly the same on both sides.

• Representing timezone list

  - by StasM

  I have a web application that allows the user to choose the timezone from the list. The list is very long (pretty much all CLDR-supported timezones). So the question is - how should I represent it? How should it be sorted - alphabetically or by timezone offset? What information should each item contain - offset, location, long name (like Europe/Zurich) or short name (like CET)? Should I display information about DST or only current offset? Let's say I can't right now do something like fancy maps OS configuration dialogs display, so the list is the only option. However I want to make the list look nice. Any best practices how it's done?

  OS: Ubuntu 12.04 LTS Problem 1: When installing anything (or updating) it always ends with this error: Errors were encountered while processing: linux-image-3.8.0-36-generic linux-image-3.8.0-38-generic linux-image-generic-lts-raring linux-generic-lts-raring Problem 2: When installing or updating stuff it opens some grub files and halts execution until I close these grub files. See screenshot below. Grub files + terminal window (screenshot) Pastebin with terminal output while trying to install something I should mention that I don't known if these two errors are related, but it is a fact that every time I try to install something or run an update both of the above errors pop up.

• Ubuntu won't stay installed

  - by tommythm227

  I recently experienced OS problems with Windows 8 so I decided to wipe my hard drive and install Ubuntu using a usb boot. I am able to "Try Ubuntu" or choose to install instantly, however, after installation it asks me to restart my computer but when I do this I receive the same installation options I originally had, "Try Ubuntu", "Install", "OEM Install", "Repair Disk". I initially thought this was the result of leaving the boot usb in, so I tried reinstalling, but now I just receive a message saying "No boot disc or boot disc failed". This happens with any type of install I do, I've tried clearing the hard drive multiple times, making a new boot usb, but nothing seems to help. I've tried reinstalling windows, but I encounter the same problem, without the usb I get an error. I have an Acer Aspire M3470, I cleared my hard drive and attempting to install via usb boot. I have a weird BIOS menu probably because of AMD but it's been hard to find information regarding my particular BIOS menu. HERE is an image of my BIOS menu

• Facter - custom fact, returns empty data set when invoked by Puppet agent

  - by user3684494

  According to this puppet labs article, I can create custom facts from shell scripts. I have created a bash script that returns a single fact, it is packaged in a modules facts.d directory. The module is included on the target system via an ENC class. When invoked by the puppet agent on the target it returns an empty set, when run by hand on the agent it correctly returns the fact. The script has execute permission on the master, but does not have it on the agent. I saw a bug report related to permissions and file types, but that was windows and supposed to be fixed in puppet version 3. What am I doing wrong? ENC definition: --- classes: facttest: Shell script: #!/bin/bash echo "test_fact1=$(hostname)" Permissions: master: -rwxr-xr-x 1 root root ... modules/facttest/facts.d/testfact.sh agent: -rw-r--r-- 1 root root ... /var/lib/puppet/facts.d/testfact.sh Agent message: Fact file /var/lib/puppet/facts.d/testfact.sh was parsed but returned an empty data set Version information: Puppet master: 3.5.1 (Debian) Facter master: 2.0.1 Puppet agent: 3.6.1 (OpenSUSE) Facter agent: 2.0.1

• Is porting a Windows application to Mac worth it? [closed]

  - by mikel

  I have a C# Windows application that sells for $35, and fairly regularly receive requests for a version for OS X too. I don't have any experience with Mac so far though, and so am not sure exactly how much work that would involve and if it would be worth it. If anyone's been in a similar position, it'd be very helpful to know: Roughly how many more (%) sales can you expect by porting to Mac ? Would you say it's worth the investment of a new Macbook Pro and the time of learning and porting to Objective-C ? Thanks in advance.

• usb drive filesystem?

  - by purbleguy

  So, school is approaching quickly, and one of the things on my supply list is a usb drive. Now I'm asking myself what filesystem to use. After some research, I found ext4 to be the most stable drive filesystem. But, I also found that Windows (The OS used by every computer in my school) can't read ext4 formatted drives without special drivers, and I'm sure the school wouldn't be too happy with me having to install the windows ext4 drivers on every computer I use with my usb. So, my question is, Should I use fat32, one of the ext filesystems (2, 3 or 4 would work) or NTFS, I have an ubuntu laptop, a Mac desktop, and of course the school computers I use are Windows, so which would be the best filesystem for my usb.

• System checks for disk drive error every time it boots

  - by Starx

  When my disk space for the ubuntu installation partition was getting low, from a live cd, I used gparted to increase its volume capacity, but deleting another partition and merging it to the ubuntu partition.

• Les ordinateurs sous Linux enverraient proportionnellement plus de spams que les autres, d'après Sym

  Les ordinateurs sous Linux enverraient proportionnellement plus de spams que les autres, d'après Symantec Malgré le peu de parts de marché détenues par Linux, les ordinateurs équipés par ce système serait les plus gros expéditeurs de spam. Symantec et ses chercheurs experts en sécurité informatique ont scrupuleusement étudié les spams envoyés entre novembre 2009 et mars 2010 afin d'identifier le système d'exploitation installé sur l'ordinateur propulsant les pourriels. Cela a été possible en utilisant la méthode dite du fingerprint passif, qui consiste à analyser le trafic réseau d'un hôte à distance, ce qui révèle l'OS de cet hôte.

• Lexmark X7170 shows documents as printed when they haven't

  - by Mehmet

  I made the move from Windows 7 to Ubuntu not dual booting because I have decided to quit gaming to spare more time for my studies. I just needed an OS for browsing the web and word processing etc. After I installed Ubuntu I installed the AMD GPU drivers, after which I clicked on the little printer icon, selected add printer and it found the drivers for the Lexmark 7000 series and I installed them. Now my problem is when I print something from Writer it processes it thinks its completed it, when in fact it hasn't printed anything. I tried printing a test page but it was stuck on processing for 5 minutes. I have restarted my computer and turned the printer on and off. I'm running 64bit if that changes anything.

• Computer Freezes After GRUB

  - by paulmcg421

  Ok so I've just built my first computer and have got it running, here are the specs: Asus P8Z68-V PCI-E LX Motherboard, Intel Core i5-2500K, Patriot Memory 8GB (2 x 4GB), Viper Xtreme Series PC3-15000 1866MHz CL9 Division 2 Edition Memory (PXD38G1866ELK), Gigabyte ATI Radeon 6850 820MHz 1GB PCI-E HDMI OC Windforce 2x 500w Ezcool 24pin psu as standard. The only thing I haven't bought new is the hard drive, it's a 250gb that I removed from an Acer Aspire M5100 that I was using till now with no OS Problems. On start up it runs fine but is unresponsive after the GRUB menu disappears to load Ubuntu (Oneric Ocelot). The keyboard lights then turn off and the screen eventually returns that there is no signal. Is there anything that I could be missing from building? (This is my first attempt at building my own PC) Any input would be appreciated, thanks !

  - by Josefvz

  Hey Folks. I'm lost... I'm using Windows 7 Ultimate 64bit. My Pc is up to date(windows updates) and I've used Winutilities to scan my registry. My explorer.exe keeps on crashing. Just randomly it seems. I don't even need to be doing anything particular. I do have experience with pc in general as I'm a software developer. I know you will require additional info, but i don't know what, so just leave a comment and I'll update. Additional info I think i should also mention that explorer is the only app that crashes on my pc. The crash report i got now: Description: A problem caused this program to stop interacting with Windows.

• How often should saving to disk occur in an automatically saving text editor?

  - by lelandmiller

  I am developing a simple text editor and would like the application to save the text automatically. In other words, the user would never have to press a save button. I have seen other applications that do this, and was wondering how often is it safe to write files to disk? From a user experience standpoint, it seems that the more frequently this happens the better, but I am worried about performance and possible disk wear (especially on writes to SSDs). It seems like the operating system disk caching might help avoid these problems, but I also don't know if its safe to rely on that for an application like this. I was planning on writing the whole document to disk at each save, but this just seems terribly inefficient if the OS ends up writing it to disk to frequently, but relying on program unload may lose data in the case of a crash. Does anyone have any experience dealing with this that might be able to help?

  I have an old Gateway MX6920 laptop that got a virus on its hard drive so I put in a new one from another laptop. When i turn it on it tries to load Windows but fails so I'm going to try to put Ubuntu on it (because I heard it's a good OS). I downloaded the 32-bit desktop version of Ubuntu and burned it to a CD. I put the CD in the computer, went to the boot menu, and selected CD-ROM. The computer tries to boot but stops at a black screen with a mouse icon sitting in the middle of the display.

• Le marché des tablettes Android sera fragmenté, mais cela sera-t-il réellement un problème ?

  Le marché des tablettes Android sera fragmenté, mais cela sera-t-il réellement un problème ? Avant même d'avoir commencé a décoller, le marché des tablettes Android rencontre déjà un sérieux problème. Il est fragmenté. En effet, la toute dernière mouture de l'OS (Honeycomb) a besoin de processeurs puissants pour fonctionner convenablement. Ce qui signifie que les anciens appareils équipés de versions précédentes du logiciel de Google ne pourront faire le pas en avant nécessaire à l'upgrade. Autre conséquence : les premières tablettes équipées d'Android 3.0 seront assez coûteuses, histoire de pouvoir suivre la cadence. Ce contexte pourrait pousser les constructeurs a concevoir des modèles...

• Creating Ubuntu bootable disk on my phone

  - by Aerus

  I want to install Ubuntu 12.04 on my laptop but because I have a complete shortage of writable CDs and DVDs, I wan't to create a bootable USB stick (on Windows). However, the only USB stick I currently have lying around is my HTC phone (HTC Touch HD with 8Gb memory). I was following the Ubuntu guide to create a bootable usb stick with pendrivelinux, however in the last step it shows me that it wants to do more than just copying the .iso file to the USB drive: My question: can I safely proceed without wiping the current OS off my phone (Windows Mobile 6.1) and use it to install Ubuntu?
