• How to get past black screen with mouse icon while installing on Gateway MX6920?

  - by tom kruse

  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. I have no idea what's going on, so please help.

  - by Aldrin

  I've got a problem. I've tried booting it from a 4gb FlashDrive many times and yet, it'll just show me blinking dots. I've tried the options (booting from first drive, trying ubuntu without installing, help, test memory). I cant! I've also tried Ubuntu 11.10 but the turns out the same. Additional specs: First HDD, 2 partitions, C: and E: by Windows. Second HDD, 2 partitions, F: and G: by Windows. First HDD: 40Gb, Second HDD: 32Gb. I've made the Second HDD blank and plan to install Ubuntu there. Any help will do. I've tried both of the ISO images of both Linux Distros, but it didn't work. Both of them results to these. HELP "Registered protocol family 1", then "_", Boot from first hard drive Cannot load a ramdisk with an old kernel image.

• 12.04 LTS won't install from CD

  - by Rob Hays

  I've been trying to install 12.04 LTS onto a Dell with a PIII from CD. Booting from the CD the install gets through the "Who are you" process, begins copying files. The progress bar gets as far as the last period in "Copying files...". The box clears, and an error box comes up "The installer has encountered an unrecoverable error. A desktop session will now be run so that you may investigae the problem or try installing again." When I try to install from this desktop session, the install gets to the same point, the copying files box closes, and then just stops. The pointer is busy, the cd drive spins up occaisonally with no data transfer, no hard drive activity. When I boot from the CD and access the disk boot menu, the disk checks good, memory checks good ( I upgraded the original memory to 512 mb). I also updated the bios to the newest from Dell. This is an older L866r, but should meet the requirements.

• How do I migrate web files from a Plesk 8 installation (on a slaved HDD) to a Plesk 10.4.4 installation?

  - by Ranger

  Due to Plesk 8 being at End of Support our host setup a new installation of RHEL and Plesk 10 on a new hard drive. They then slaved the old drive to the new so that we could migrate all our files using SSH. I am having challenges correctly migrating the sub domain files. The path to subdomain root folder in Plesk 10.4.4 is confusing as I don't know where to copy the files to. The path to the files on the slaved drive is: "/mnt/old-drive/var/www/vhosts/domain_name.com/subdomains/SUBDOMAIN_NAME/", meanwhile on the new installation I have "/var/www/vhosts/SUBDOMAIN_NAME.domain_name.com". There is an httpdocs folder in the '/var/www/vhosts/domain_name' folder but none in the '/var/www/vhosts/SUBDOMAIN_NAME.domain_name.com' folder. Where do I copy my subdomain files to? Please help.

• how to give meaningful id to the things in database

  - by gcc

  There are a lot of manuals. I am trying to create an database to hold information of these documents. But, there is a small problem. How can I give meaningful id to the manuals? Are there any standard or logic behind the giving meaningful id to the documents? If there is no standard, can you tell me how I should do that? example: table : manual id | manual name EDIT: Not Meaningful ID 1 or M1 or foo 2 C2 bar 3 P123 name ... ... ... (i) (ii) (iii) (i) Not meaningful for me because if some item deleted, there can be gap. ex 1 33 100. (ii) random character can be confusing when one try to give a name to new manual (iii) Why giving name is not preferred is because finding a name to the manual as ID is hard after 500 manuals. Meaningful : New ID * Can be easily produced even if after 1000 manuals * Should not be so complicated

• Time it would take me to learn c++ given my speed? [closed]

  - by ashwin

  I am a student in second year of engineering and my life is hard, nowadays. To make my future secure and at least get good jobs, I have started learning C++; I have learned J2SE, ASP.NET (little, basic C#), PHP (little), HTML, CSS, AJAX, Javascript, SQL, a little android development (I have built a benchmark app) in 4 months and have received 1 gold medal in CSS and 1 each in HTML, CSS, Java. I am able to make things in C#, Java and all other, so I can apply all this knowledge. I was able to do all this, because I loved learning and I hate to ask this question. How much time would it take me to learn C++, good-enough to get good jobs at Google, Microsoft? I am currently learning data structures, so that's excluded.

• Alerts are good, aren't they?

  - by fatherjack

  It is accepted best practise to set some alerts on every SQL instance you install. They aren't particularly well publicised but I have never seen any one not recommend setting up alerts for Error 823, 824 and 825. These alerts are focussed on successful access(IO) to the hard drives that SQL Server is using. If there are  any errors when reading or writing to the drives then one of these errors will be returned. Having the alerts on these errors means that any IO issues will be brought to the...(read more)

• How to get the Dash and HUD to appear. (and stop Unity spewing error messages.)

  - by Ubuntiac

  I just installed Ubuntu 12.04 on my wifes Dell Inspiron 1501, which uses an R300 ATI graphics chip. Neither the Dash or HUD appear when pushing the appropriate key. When I try unity --reset & in the terminal, I see that over and over it's spitting out: r300: CS space validation failed. (not enough memory?) Skipping rendering. This is just after starting Ubuntu with no apps open, so I find it hard to believe that just rendering the Dash / HUD is completely blowing out the VRAM. Any suggestions on getting this working? /usr/lib/nux/unity_support_test -p shows OpenGL vendor string: X.Org R300 Project OpenGL renderer string: Gallium 0.4 on ATI RS480 OpenGL version string: 2.1 Mesa 8.0.2 Not software rendered: yes Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: yes All sections say "YES"

• How do I save to an NTFS partition?

  - by RADHAKRISHNAN

  I was using ubuntu 11.04 on my Laptop. While installing it from a DVD, I have created a 10 GB NTFS partition at the beginning of the hard disk, as primary. All other partitions ( swap, a ext3, a ext4 and a FAT32 ) are created in as logical in the extended partition. All were working well in ubuntun11.04. Now the system was upgraded to ubuntu 11.10 via internet and was sucessful. But unable to either create folder/files or to write to existing files in the said NTFS partiton. But files in the partition can read - means mounting done. Same is the case even if logged in as root also. Fortunately no such problem with other partitions including FAT Why it is so, please help.

• Do you think that in the future it'll be possible to develop games on OS X by using Python and the latest library "Sprite kit" made by Apple? [on hold]

  - by Cesco

  I don't understand a lot about game engines and modules for Python, even though I'm aware of the existance of PyGame and Pyglets, so please don't bash me too hard if I'll wrote something wrong in this question :-) When I upgraded my Mac to the latest version of OS X, I noticed for the first time that Apple is providing a library named Sprite kit for developing games on both iOS and OS X. It looks to me fairly complete, and the fact is managed by a big company gives me the impression of being well-supported for the time being; in summary, it looks... cool. Actually in order to take advantage of "Sprite kit" you need to code in Obj-C. Since I don't know Obj-C but only a little bit of Python, do you think that there's a chance that sooner or later someone will make a wrapper for Python ? Thank you very much and best regards

• Windows 8 and "Formerly known as Metro" apps, an experience with PDF app

  - by Kevin Shyr

  I'm slowing and surely getting used to Windows 8.  It is no doubt a slow process since I still run daily on an XP machine, a Vista machine, and 3 windows 7 box. A new quirk I found regarding Windows 8.  I never thought it was important to learn how to close a "formerly known as Metro" app (what do we call those these days?).  Then I attached a portable drive to my laptop and opened up a PDF file, and I couldn't safely remove the hard drive afterwards because I did not know how to close the PDF reader app. I have since learned that if you want to close an app, you can try Alt + F4 mouse over the top left corner and swipe down, right-click to close you app Windows Key + TAB, right-click to close the app All these make me wonder, how do you do this in a phone or tablet?

• Refactoring While Programming

  - by Kirby

  When posed with a problem, particularly when it is complicated in nature, I try to take some time to think about the approach I am going to take to solve the problem. Despite this, what often happens is, as I am programming the solution, I start to think of details of the problem that I missed, and I adjust the code accordingly. What results is a mess of code that needs to be refactored. I want to "refactor as I go," but while it sounds easy enough to do, I have a really hard time doing it. When the detail that I missed is small, it is tempting to make a small update to my design, rather than erase what I've already written and write it the way it is supposed to be. It sounds like a question with an obvious answer, but are there any techniques to use to better "refactor as you go"? I know that this is a good principle, but I fail with it time and time again.

• Ubuntu will not load up from my USB

  - by Ryan Mungwira

  I have a Sony Vaio Duo 13 and I am trying to get Ubuntu 13.10 to run on a partition on my Ultrabook but it will not load up from the USB drive. It goes to the black screen that asks if you just want to Try Ubuntu or if you want to Install it. I click just to try and it will not load. It acts like it is going to start up but then it just goes to a blank black screen and then I have to a hard restart. It does that when I click install as well. And I have tried disabling the Secure Install on my computer as well and nothing happens! What do I do?!?

• Ad networks that will serve via HTTPS?

  - by Dogweather

  I've built a website with 160K page views per month that serves every page over HTTPS. The recent FireSheep news will probably increase the adoption of "HTTPS everywhere" but it's been very hard to find ad networks and affiliates that will serve their content via HTTPS. I don't want to use these because I don't want my visitors to get "broken security" notification from their browsers (and of course, relevant ads would be a leak of private information). I'm tired of spending a ton of time signing up with ad networks and affiliates only to find out down the road that they don't support HTTPS (e.g. AdSense). Can anyone suggest any options or provide a pointer to a list of these somewhere?

• What is the best certification for the self-taught ASP.Net programmer? [closed]

  - by Wahid Bitar

  I learned the C#.Net language from books and many other resources then i did some good projects with ASP.Net "Web Forms & MVC". But i wanna a good certificate to get a better work out of my country as i suppose. I've two choices: Apply for a " college / institute " and start study academic courses to be more professional and maybe in two years I'll "hopefully" graduate with this college certificate. Apply for kind of " Certifications by Companies " like MCTS from Microsoft or something like that and study their straightforward courses then maybe with three or four months I'll get this "Not official Certificate". Is the second type of certifications good for learning and work or the best is the hard way ?. Please give me advises with certifications names please. ======================= Update: This is not related to certain country or region. I'm asking about a good certification and courses for an ASP.Net and C# in general programmer.

• Stuck at boot, both with wubi and USB

  - by Christoffer

  I have tried installing Ubuntu 12.04 through USB and with wubi interface. Nothing works. With USB, I will enter the main menu, doesn't matter what i choose, "install ubuntu on a hard drive" or "boot into ubuntu from USB". When I click on one of those it will scan my drives or something, and when it gets to the USB it gets stuck. It just stays there.... With wubi, the install goes fine, but when trying to boot for the first time to ubuntu it says "completing ubuntu installation"... NOTHING more happens, that cursor only blinks there. How can I get Ubuntu to work??? I got: 1TB HDD, 256GB HDD, 80GB SSD. I'm trying to install Ubuntu on my 256 GB HDD....

• List of backlinks to a specific website, listed by decreasing PageRank

  - by Nicolas Raoul

  With backlinkwatch.com I can get a list of pages that link to a particular website. Unfortunately, it lists tons of obscure blogs and small forums, it has hard to find what link is really important. Is there a similar service, where links would be displayed sorted by "importance"? For instance, a link New York Times would be shown at the top of the list, while links in small blogs would not appear before a few pages. "Importance" can be subjective, so I suggest using the PageRank, but other metrics could be fine too.

• Is it possible to outsource design properly?

  - by Eric

  I work in a company going through a downsizing process. It is assumed that a lot of "let go" developers jobs will eventually be outsourced. Some of those programmers had some design to do. Is it possible to outsource both design and creation/coding properly? I feel that by outsourcing design, we lose any in-house capability of really "owning" the code. It will be very difficult to maintain. Also we'll have a hard time ensuring a proper development. How can I address those issues?

• The #OOW Party May Over...

  - by user462779

  ...but there's no reason why we can't look forward to the next one! It's going to take all week for me to catch up on last week's neglected email, sort through the freshly-collected business cards, and generally make sense of the mad dash that is Oracle OpenWorld. So I've been playing this amazing video (produced by Lozano Productions) to remind me of the last business/IT conference marathon I survived: Collaborate 2012. It was an amazing event where we officially launched the new design of Profit and enjoyed a drink with some of our closest friends--Oracle partners, customers, and peers. Many thanks to those who came out to celebrate and who continue to help make Profit a success. It was a great time that resulted in a lot of great new work and new relationships. So I'm taking a time out to remember that the hard work is worth it. See you in Denver next year!

• Oneiric is freezing. Need help diagnosing and filing a bug

  - by mlissner

  Six months ago, I bought a new Sandy Bridge CPU and built myself a nice desktop machine. Until now it hasn't worked...at all. I finally have gotten it working now that Oneiric is released, but it freezes every so often, making it little more than a semi-functional temptation. What happens when the system freezes is: the music I have playing enters into about 5s loops. SSH fails the monitor freezes the mouse freezes the keyboard fails The only way to fix it is to do a hard reset...and that sucks. I'd love to at least figure out the source of the freeze so I can file a bug. I've looked in dmesg, kern.log, and the X.org logs. Nothing interesting is any of them. Since SSH fails, I'm convinced it's not an X crash: https://wiki.ubuntu.com/X/Troubleshooting/Freeze Anything else I can do?

• How do I run update-grub from a LiveCD?

  - by Kelley

  Okay, so I did something stupid. I was trying to clean up my Grub entries, and accidentally removed all of my Linux kernels from Grub (they're still on the hard drive). So now, obviously, Grub doesn't give me any way to boot into Ubuntu; I can boot into Windows just fine, but Ubuntu isn't even listed. So I just want to run "sudo upgrade-grub" somehow to restore Ubuntu to the list. I can boot from a LiveCD, but once there how do I run that command? (My Ubuntu installation is on sda5, by the way.)

• Updating and organizing class diagrams in a growing C++ project

  - by vanna

  I am working on a C++ project that is getting bigger and bigger. I do a lot of UML so it is not really hard to explain my work to co-workers. Lately though I implemented a lot of new features and I gave up updating by hand my Dia UML diagrams. I once used the class diagram of Visual Studio, which is my IDE but didn't get clear results. I need to show my work on a regular basis and I would like to be as clear as possible. Is there any tool that could generate a sort of organized map of my work (namespaces, classes, interactions, etc.) ?
