• Repartitioning in 14.94 To Add Home Partion

  - by Chaim Frazer

  I have 32 bit 14.04 installed as the only OS on a older Toshiba Laptop. Unfortunately, when I installed it I did not set up a \home partition, which I had intended to do. What I want to do is to set up a \home partition and to transfer the files in my current \home directory to it. I have a 14.04 Live CD, so I could reinstall 14.04. I also have GParted on a Live CD. If I use GParted, I need precise instructions about how to proceed. I have plenty of disk space (200 GB) for either alternative and know how to decide space allocation for Linux partitions. How should I proceed? Thanking you in advance. Chaim Frazer

• Lipoaspiration in your SQL Server Database

  Once, when disk space was at a premium, DBAs fought hard to keep the size of their database down. Now there seems less motivation to 'fight the flab' of a database. Fabiano Amorim was watching television recently when the subject matter, cosmetic surgery, gave him the theme and inspiration for this guide to keeping your database fit and trim.

• Ubuntu 12.04 won't boot from USB

  - by user986871

  I downloaded Ubuntu 12.04, then using the tool Startup Disk Creator i made the live usb. I checked that it's bootable Device Boot Start End Blocks Id System /dev/sdb1 * 62 15635593 7817766 c W95 FAT32 (LBA) Now on my lap top it boots nicely, but on two other machines that don't have any installation of ubuntu(no Grub) it doesn't boot. I changed the booting order so that USB is before HDD. So i think i did everything i know, but no luck. How can i use this USB drive on other devices that don't have any previous ubuntu installation.

• What should be the correct ownership of /tmp /var /usr and subdirectories?

  - by sbergeron

  For some reason I think the permissions of those were messed up from a small amount of disk corruption I had. This may be a dupe, I don't know but I googled it and didn't find any mention of it. I need to know how the permissions of them should be set up as currently my computer can't actually use the tmp directory and I can't download anything consequently. I have access to the recovery mode command line but while in sudo user prompts it doesn't seem to work correctly. Also something is wrong with package management and I get dpkg: error: unable to access dpkg status area: read-only file system. I know my system is really messed up but I don't want to have to reinstall AGAIN.

• How to access the SD card through my Sony Ericsson Xperia Arc Phone?

  - by user16364

  I have a Sony Ericsson Xperia Arc phone and I cannot access its SD card through the USB cable provided. I have set the USB connection mode to MSC yet when I connect the phone to my computer I cannot see the SD card (or anything for that matter). The Disk Utility however, does see an SEMC Mass Storage device but it says that no media was detected. I have validated that the SD card works as I removed it from the camera and plugged it into a card reader and saw all the photos and files stored on it. I have validated that the phone works as I have connected it (in MSC mode) to my wife's Windows 7 computer. Can anyone please tell me how I can access the SD card on my phone.

• 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.

• Ubuntu One lost most of my files!

  - by Max

  I keep in my UbuntuOne the source code of my projects as a back up. In the past it worked and I never had problem. It happened that I had to change the hard disk of my laptop and I installed a fresh Ubuntu 12.10 in the new one. First time I connected with UbuntuOne it downloaded my files, but when I went to see my projects almost all my c++ source code files were missing!!!... I tried to check if I still have them on UbuntuOne by accessing from the web but nothing... my work is lost forever. I don't know who to ask for help? Is there a way to get back my precious files? Honestly I can't trust this service any more, I'm very disappointed. (edit: thanks God I found a back up in one of my external hard disks. I won't trust Ubuntu One any more, it's buggy and quite slow. )

• Automatically delete files after they expire

  - by Auxiliary

  I've got this idea for some time and I was wondering if anyone has seen such a feature/app in any operating system and if you haven't, what do you think about it. Where do you think I should begin? The idea is simple. I think we all have those files that are made and probably used for a few days and then are left on our disk and we never delete them or even check to see if we need them again. It'd be cool if you could right click on a file and click on "Expire in.. 3 days" for example. And the file gets deleted after 3 days. I have a great need for this and maybe some people will find it useful. I was thinking of writing a script and use the Nautilus Action project in GNOME for a start.

• Neither suspend nor hibernate in 12.10 lubuntu - is there a workaround by scripts?

  - by J.-S. Farinet

  I've neither suspend to ram nor to disk in 12.10 lubuntu (i suspect there might be a kernel issue but i'm only a simple user). Also, the xfce powermanagement which comes with lubuntu by default does not have any effect. Even it doesn't lock the screen when i set this in the preferences: What do when close the lid. So, on a portable that's annoying a lot. Is there some way to workaround by scripts in 'etc/pm/*.d'? TIA for any idea.

• Ubuntu 12.04 mdadm inactive

  - by user32274

  For a while now, my RAID 5 has ceased to work. Everytime I tried "madm --detail /dev/md127", its states all the drive and drive info, but that two of the drives have been removed. After some restarts, doing the same thing, i am getting /dev/md127 does not appear to be active. When I go into DiskUtil, I can see all 6 Hard Drives healthy and present, and i can see the Raid 5 at the bottom under Multi-disk Devices. However, the Raid says 0.0kb, and is not active. Please help and let me know how to proceed from here. I would really like to avoid rebuilding the RAID, especially because all 6 drives seem to be healthy and present. Thanks so much.

• Maxtor OneTouch Hardisk Not Recognised

  - by user8960

  I have a Maxtor OneTouch External Harddisk 160gb that i purchased recently. At first my Ubuntu 10.10 could not mount it. I opened disk utility which recognized it but with no filesystem. I proceeded to try formatting it but this error popped up Blockquote Error creating partition table: helper exited with exit code 1: Error calling fsync(2) on /dev/sdb: Input/output error Blockquote I resorted to Gparted. Things turned worse; it wasn't even listed in the list of devices. Does anyone have a solution to this problem? Any help is appreciated.

• What makes Java so suitable for writing NoSQL Databases

  - by good_computer

  Looking at this page that aggregates the current NoSQL landscape, one can see that the majority of these projects are written in Java. Databases are complex systems software dealing with the file system, and so C/C++ would be a better choice than Java for this. (that's my thinking which might be flawed) Secondly, databases deal with transferring large amounts of data from disk to RAM -- which they call a working set. The JVM takes non-trivial amount of RAM for it's own purpose -- so it would be more efficient to use a platform that leaves lots of memory for data instead of hogging it for its own operations. The major relational databases are ALL written in C/C++ MySQL C, C++ Oracle Assembler, C, C++ SQL Server C++ PostgreSQL C SQLite C So what makes Java so popular in NoSQL world.

• Having problem to login after upgrading from 11.10 to 12.04

  - by LinuxIsMyFriend

  I just update to 12.04 from 11.10 and I get to the login screen w/o problems. When I enter my password the screen turns black and returns to the login screen half a second later. There is a related question out there which was solved by creating more space on the disk but my disks (or rather partitions) are all below 30%. I can log in as guest. I can also login at the cmd prompt (going to tty with Alt+Ctrl+F1) with my normal user credentials. When logged in as guest I can also install programs using my normal account password. There is the normal authentication error when I mistype my password so I'm also sure the password works. Any suggestions?

• SSMS Slow To Save

  - by Bunch

  When using SSMS 2008 I found it to be really slow when trying to save a file, even a small one with just some simple SELECT statements on it. The symptoms were the flashing save disk icons in the lower right corner and selecting the location to save in the Save File dialog would hang each time I picked a location (e.g. Libraries, a folder). This was the first I had seen anything like this where it was really, really slow. It ended up that a server had died last week and I was still mapping a drive to it. SSMS was still trying to connect to it causing the slow down (further information here and here). Once I removed that the save functionality worked like it should. Tags: SQL

• Opening programs very slow on ubuntu 12.10

  - by Mislav Blaževic

  When I open any program for first time after boot, it loads VERY slowly (Doesn't matter how long after boot). For example, terminal takes 2-3 seconds, skype and firefox often take much longer. If I close it and open again, it loads in reasonable time (<1 second). I got Intel Core i5-2500K CPU @ 3.30GHz, so it shouldn't be hardware issue... What is causing this? Disk benchmark: Average read time: 115.5 MB/s (100 samples) Average write time: 98.7 MB/s (100 samples) Average access time: 11.79 msec (1000 samples)
