• Discussion of a Distributed Data Storage implementation

  - by fegol

  I want to implement a distributed data storage using a client/server architecture. Each data item will be stored persistently in disk in one of several remote servers. The client uses a library to update and query the data, shielding the client from its actual location. This should allow a client to associate keys (String) to values(byte[]), much as a Map does. The system must ensure that the amount of data stored in each server is approximately the same. The set of servers is known beforehand by other servers and clients. Both the client and the server will be written in Java, using sockets, threads, and files. I open this topic with the objective of discussing the best way to implement this idea, assuming simplicity, what are the issues of this implementation, performance measurements and discussion of the limitations.

• No programs or applications show up in dash

  There are no programs on the dash list (seacher on appmenu). Yesterday I logged into my account and I tried to find a particular program, but there weren't any! Additionally, I tried to view installed programs and manually find programs, but nothing was displayed. And today, when I wanted to turn on Ubuntu Software Center, it just don't turn on.

• 3 Ways to Normalize Sound Volume on Your PC

  - by Chris Hoffman

  If you’re constantly adjusting your computer’s volume while you watch videos or play music, there’s a better way. You can set a consistent volume level, either Windows-wide or in a specific program like VLC or your music player. Many applications have “volume normalization” or “loudness equalization” features built-in, including Windows itself. These features are often somewhat hidden and off the beaten path, so you won’t find them unless you go looking for them.

• PHP accessible shared content between two websites on the same VPS on different domains/IPs

  - by Lee Fentress

  I have two ecommerce websites, selling music digital downloads, on the same VPS, currently using cPanel/WHM (but thinking of switching to Virtualmin). They have separate domains and IPs of course. They both share from the same set of music files, so I have duplicate copies in each website directory, which takes up a lot of disk space. How might I go about sharing the same set of music files across both sites, allowing PHP access, so that it does not break my shopping cart's functionality of serving customers the downloads after they have paid for them? I thought of maybe using symlinks or something, but I don't know if it's possible, or if it would have to somehow circumvent built-in security features of the server. I'm new to VPS management.

• How can I get wireless working on an HP-Mini 110-3150?

  - by jfmessier

  I just got an HP Mini 110-3150, and booting from an external hard disk with Ubuntu 10.10 works all fine, except that there is no wireless detected. I noticed that the Wireless indicator is red under Ubuntu, but is enabled under whatever Windows 7 I got on it. So, I understand that it may not get detected at all by Ubuntu at startup time, and there is no manual switch that I can simply slide to turn on/off. How can I get the Wireless device turned ON by default at startup time, and is there any special driver I need to install (proprietary or not) to get it working ? Merci :-) Update: When actually installing on the computer, as a new install, the NIC is not detected at first, but upon restarting, I get a notification of a closed driver available for the wireless. Once installed, updated and restarted, it works fine.

• Will a Wubi install of Ubuntu effect my Windows installation in anyway? [closed]

  - by Oddysee

  Possible Duplicate: What are the benefits of a disk install vs. Wubi? And can I migrate my settings easily? Having never tried a Linux OS before, I want to dabble and take a look at one. Ubuntu seems like a good distro to go with (due to how popular it is) and I want to use Wubi to try it out. I just wanted to know if anything I do while trying out Ubuntu will effect my Windows Installation or the files pertaining to it in anyway? If so, is it potentially Windows breaking?

• Install/upgrade ubuntu from another system

  - by Samarth Agarwal

  I have a new Laptop with latest Ubuntu preinstalled on it, its 12.04. I have another laptop with Ubuntu 10.04 on it. What I lack is a fast internet connection. I want to upgrade my Ubuntu 10 laptop to a ubuntu 12 version. How is this possible without using internet connection? Can I move/copy the installation from the new laptop to the older one? Is there a way so that the newer laptop can upgrade the older one using a usb disk or dvd/cd?

• High I/O wait after login

  - by Jackson Tan

  I've noticed that the ubuntuone-syncdaemon hogs up the hard disk every time I log in to Ubuntu (10.04). This takes up to two or three minutes, which makes Ubuntu insufferably slow. Opening Firefox is okay, but the browser is constantly greyed out and lags horribly. Given that I often shut down my laptop when I don't use it (about 3 to 4 times a day), this makes Ubuntu lose much of its lustre because of its long boot time. Is this a normal behaviour of Ubuntu One? Is it intended? Note that I've actually posted this in the forums here, but I received only few replies.

• Can't install Ubuntu on a HP DV6 Laptop

  - by EApubs

  I just bought a HP DV6 6011tx (link) Laptop. I formated the disk through Windows and prepared for installing Ubuntu. But when I inserted the live CD, it showed the Ubuntu start screen and then everything went black. There was no cursor, everything just stayed black like the screen was switched off (but the system is running). When I tried to install from the USB, it said Live media is not found. Sometimes it also gave me a black screen like the CD. Does anyone have any idea how to fix this? Thanks!

• Ubuntu partitions on Dell XPS13

  - by Francois

  I bought a Dell XPS13 with ubuntu 12.04 pre-installed. I want to reformat and repartition the machine but as I'm far from being a linux guru, I'm afraid to erase something important that could have been preinstalled by Dell. On the disk, there are 3 partitions: /dev/sda1 - Ext4 Linux bootable 248GB - witch is the system+user partition I guess, /dev/sda2 - Extended (?) of 8GB - What is this partion about? /dev/sda5 - Linux Swap of 8GB - whitch is for RAM and need to be reconduct (why only 1xRAM and not 2?) Do I have to care about /dev/sda2 ? According to you can I reformat to create a partition for /home whitout losing anything important (except user data of course) ? Thank you for your help

• Existing Instance, Shiny New Disks

  - by merrillaldrich

  Migrating an Instance of SQL Server to New Disks I get to do something pretty entertaining this week – migrate SQL instances on a 2008 cluster from one disk array to another! Zut alors! I am so excited I can hardly contain myself, so let’s get started. (Only a DBA could love this stuff, am I right? I know.) Anyway, here’s one method of many to migrate your data. Assumption : this is a host-based migration, which just means I’m using the Windows file system to push the data from one set of SAN disks...(read more)

• The /usr/bin/x11 folder

  - by WrecklessT

  Why does the /usr/bin/x11 folder hold another x11 folder and when you open that === x11 you get another x11 and then another and another??? I did it about 6 times and got frustrated so I have no idea how deep this goes but What is the purpose (or is it a glich?)? Is this eating disk space more than it should? (I was going to delete one or more but thought I better ask first before I end up !fucked ) and finally Is it just me and I am going crazy maybe the pills are wearing off or maybe they are kicking in.. I am not sure but an answer would help. I can see no reason why this should be happening at all.

• What are the advantages and disadventages of git or bzr + rsync vs rdiff-backup?

  - by Azendale

  I used to use rsync to do backups, but then I switched to rdiff-backup to incremental backups. Recently, I discovered git and bzr while working on a coding project. So, I was thinking, I could have my backup disk be a repository in either git or bzr. Then I could rsync to the repository, and commit the changes. Would there be any performance concerns with this? Any other issues that I'm not thinking of? The benefit I see in using rsync is that you can restart an interrupted transfer, while rdiff-backup reverts to the last version, and then starts again. Any reason not to do it this way? Anything I'm not thinking of?

• How to Restrict Android App Permissions

  - by Chris Hoffman

  Android forces you to agree to every permission an app wants, assuming you want to use the app. After rooting your device, you can manage permissions on a per-app basis. Restricting permissions allows you to protect your contacts and other private data from apps that demand access you’d rather not allow. Many apps will continue working properly after you revoke the permissions. HTG Explains: What Is RSS and How Can I Benefit From Using It?

• How to disable the Mount notification in Gnome 3.4?

  - by Thompson

  How to disable those annoying notifications when you plug a new disk in, or connect to a network and so on.... I know that if I add a device to a mount script they will be mounted on boot thus not showing me the notification, which I did for my hard drives, but it doesn't help with all those flash disks I have... I can't add them all that would be silly. I looked at: How can I disable gnome-shell's notification area? ... but they didn't help, since the code was different I also looked at configuration editor, but I think it can only disable auto-mount when inserted, it doesn't disable notification...

• How to convert an XFS file system to HFS+

  - by user219350

  I have repeatedly convinced of the reliability of the XFS file system , and I was more than satisfied . I was happy with everything in Ubuntu 14.04 ( great software) , but there is a little "but ! " Basically, I work on OSX-Mavericks 10.9.3, which sees very Windows 8.1 and works wonders with NTFS, but does not see Ubuntu! Briefly describe the equipment: ASRock B75 Pro3-M i5 3330 GeForce GTX 650 Ti SATA 500GB running OS X Mavericks + Clover - a boot disk Toshiba 2TB running Windows 8.1 (x64) and Ubuntu 14.04 (amd64) If you boot from the Toshiba (where there is Ubuntu and boot Windows + GRUB) after restart boot from Clover, it is impossible. Tried a lot of options - as Clover installation and boot priority, and various settings for GRUB, but have not found an acceptable option and have no desire to reinstall again Clover (Mavericks reboots 20 seconds - excellent!) So please help on the file system - how to convert from XFS to HFS+ journaled. Mavericks to saw it all synced on Mac. Thank you for the sensible answer and help! Originally in Russian.

• Using the @ in SQL Azure Connections

  - by BuckWoody

  The other day I was working with a client on an application they were changing to a hybrid architecture – some data on-premise and other data in SQL Azure and Windows Azure Blob storage. I had them make a couple of corrections - the first was that all communications to SQL Azure need to be encrypted. It’s a simple addition to the connection string, depending on the library you use. Which brought up another interesting point. They had been using something that looked like this, using the .NET provider: Server=tcp:[serverName].database.windows.net;Database=myDataBase; User ID=LoginName;Password=myPassword; Trusted_Connection=False;Encrypt=True; This includes most of the formatting needed for SQL Azure. It specifies TCP as the transport mechanism, the database name is included, Trusted_Connection is off, and encryption is on. But it needed one more change: Server=tcp:[serverName].database.windows.net;Database=myDataBase; User ID=[LoginName]@[serverName];Password=myPassword; Trusted_Connection=False;Encrypt=True; Notice the difference? It’s the User ID parameter. It includes the @ symbol and the name of the server – not the whole DNS name, just the server name itself. The developers were a bit surprised, since it had been working with the first format that just used the user name. Why did both work, and why is one better than the other? It has to do with the connection library you use. For most libraries, the user name is enough. But for some libraries (subject to change so I don’t list them here) the server name parameter isn’t sent in the way the load balancer understands, so you need to include the server name right in the login, so the system can parse it correctly. Keep in mind, the string limit for that is 128 characters – so take the @ symbol and the server name into consideration for user names. The user connection info is detailed here: http://msdn.microsoft.com/en-us/library/ee336268.aspx Upshot? Include the @servername on your connection string just to be safe. And plan for that extra space…

• Uninstalling Ubuntu dual-boot bootrec issues

  - by Raymond Standen

  So on my laptop I am currently planning on uninstalling Ubuntu 12.04 so I can upgrade my Windows 7 partition to Windows 8, then install Ubuntu 12.10. My issue being that when I boot the Windows 7 recovery disk, I believe i Need to use cmd to run bootrec /fixboot and bootrec /fixmbr. Now, whilst fixmbr works, fixboot yields me with an error regarding an unrecognised volume. When I turn on my PC now, I am no longer met the GRUB option, so I boot straight into Windows. My question is: As such, do I still need to have fixboot run or can I just format and resize the partitions now even with the error when running fixboot?
