• Install GIMP 2.7.1 on Lucid Lynx using PPA

  - by Vivek

  GIMP lovers are going to be disappointed to hear that GIMP is going away in the next release of much awaited Ubuntu 10.04. Today we take a look at installing in on Lucid Lynx using PPA. The reason for getting rid of it as cited by the GIMP developers, is that GIMP is too professional a software to be included in regular desktop version of Ubuntu. And it takes up too much of space on the disk. Also, the fact that it’s too complicated for regular users. If you can’t live without it…let’s see how to install GIMP 2.7.1 on Lucid Lynx (Currently in Alpha). The new version of GIMP supports single window mode and we will also see how to enable this feature as well. First we need to add the official GIMP 2.7.1 PPA in the software sources of Ubuntu 10.04, by opening the terminal window and typing the following command: sudo sh -c “echo ‘deb http://ppa.launchpad.net/matthaeus123/mrw-gimp-svn/ubuntu lucid main’ >> /etc/apt/sources.list” Now that we have added the PPA we need to add the GPG key, so type the following in your Terminal window. sudo apt-key adv –recv-keys –keyserver keyserver.ubuntu.com 405A15CB Next up we have to update the software repository… sudo apt-get update All that is left is to install GIMP 2.7.1 by typing in the following… sudo apt-get install gimp Click ‘Y’ (for yes) to install GIMP Once GIMP is installed you can start it by going to Applications > Graphics > GNU Image Manipulation Program. You now have your favorite GIMP on your favorite Ubuntu 10.04. As you can see in the image below, GIMP still comes with default 3 windows, which could clog up your lower panel In Ubuntu 10.04. However, now you can run GIMP in single window mode by going to Windows > Single-Window mode. That’s all! Now you have your GIMP running in single window mode with less of hassle to manage 3 windows. It’s unfortunate that GIMP will not be included, but by following these instructions, you’ll be able to enjoy using it in Ubuntu 10.04.

• Upgrade Office 2003 to 2010 on XP or Run them Side by Side

  - by Mysticgeek

  If you’re still running XP, currently have Office 2003 installed on your machine, and skipped Office 2007, you might want to upgrade to Office 2010. In this guide we will show you the upgrade process or how to run them side by side. In this example we are upgrading from Office 2003 Standard to Office Professional Plus 2010 RTM (Final) on XP Professional. System Requirements To run Office 2010 on your XP machine you have to make sure you have Service Pack 3 and Microsoft Silverlight installed (links below). Or you can just install them through Windows Update. Recommended Hardware 1GHZ CPU or higher 512 MB of RAM or higher 1024×768 Resolution or higher DirectX 9.0c compatible graphics card with 64 MB of memory or higher Installing Office 2010 Simply kick off the Office Professional Plus 2010 installation. Enter in your product key… Agree to the EULA…   Select the Customize button… Setup will detect Office 2003 and allow you to remove all applications, keep them, or select only the ones you want to keep. In this example we’re going to remove Excel and PowerPoint, and keep Outlook and Word 2003. Next, click the Installation Options tab and select Office programs you want to install. Since we’re keeping Outlook 2003 and don’t want to use Outlook 2010, we’re making sure not to install Outlook 2010. However, we want to run Word 2003 and 2010 on the same machine. After you’ve made your selections click the Upgrade button. The installation begins and you’re shown the progress. The amount of time it takes to install will vary between systems. Installation is complete and you can close out of the installer. Now when you go into the Start menu under Microsoft Office, you’ll see both versions of the Office apps available. Here is a shot of Word 2003 and 2010 running together on our XP machine.   Conclusion If you’re moving from Office 2003 to 2010, this allows you to install both versions side by side. It gives you a chance to learn 2010 features, and still work in the familiar 2003 environment when you need to get things done quickly. If you’re having problems installing Office 2010 make sure to check out our article on how to fix problems upgrading Office 2010 beta to RTM (Final) release. Also, if you were using Office 2007 and are currently using the 2010 beta, we have a guide on how to switch back to Office 2007 after the 2010 beta ends.

• Should I upgrade to "Ubuntu 14.04 'Trusty Tahr'" from "Ubuntu 12.04 LTS" and what care do I need to take if I upgrade?

  - by PHPLover

  I'm basically a Web Developer(PHP Developer) by profession. I mainly work on PHP, jQuery, AJAX, Smarty, HTML and CSS, Bootstrap front-end web development framework. I've also installed and using IDEs/editors like Sublime Text, NetBeans. I'm also using Git repository for my website development as a versioning tool. I'm using "Ubuntu 12.04 LTS" on my machine almost since last two years. My machine configuraion is as follows: Memory : 3.7 GiB Processor : Intel® Core™ i3 CPU M 370 @ 2.40GHz × 4 Graphics : Unknown OS type : 64-bit Disk : 64-bit The important softwares present on my machine and which I'm using daily for my work are as follows: PHP : PHP 5.3.10-1ubuntu3.13 with Suhosin-Patch (cli) (built: Jul 7 2014 18:54:55) Copyright (c) 1997-2012 The PHP Group Zend Engine v2.3.0, Copyright (c) 1998-2012 Zend Technologies Apache web server : /usr/sbin/apachectl: 87: ulimit: error setting limit (Operation not permitted) Server version: Apache/2.2.22 (Ubuntu) Server built: Jul 22 2014 14:35:25 Server's Module Magic Number: 20051115:30 Server loaded: APR 1.4.6, APR-Util 1.3.12 Compiled using: APR 1.4.6, APR-Util 1.3.12 Architecture: 64-bit Server MPM: Prefork threaded: no forked: yes (variable process count) Server compiled with.... -D APACHE_MPM_DIR="server/mpm/prefork" -D APR_HAS_SENDFILE -D APR_HAS_MMAP -D APR_HAVE_IPV6 (IPv4-mapped addresses enabled) -D APR_USE_SYSVSEM_SERIALIZE -D APR_USE_PTHREAD_SERIALIZE -D SINGLE_LISTEN_UNSERIALIZED_ACCEPT -D APR_HAS_OTHER_CHILD -D AP_HAVE_RELIABLE_PIPED_LOGS -D DYNAMIC_MODULE_LIMIT=128 -D HTTPD_ROOT="/etc/apache2" -D SUEXEC_BIN="/usr/lib/apache2/suexec" -D DEFAULT_PIDLOG="/var/run/apache2.pid" -D DEFAULT_SCOREBOARD="logs/apache_runtime_status" -D DEFAULT_LOCKFILE="/var/run/apache2/accept.lock" -D DEFAULT_ERRORLOG="logs/error_log" -D AP_TYPES_CONFIG_FILE="mime.types" -D SERVER_CONFIG_FILE="apache2.conf" MySQL : 5.5.38-0ubuntu0.12.04.1 Smarty : 2.6.18 **NetBeans :** NetBeans IDE 8.0 (Build 201403101706) Sublime Text 2 : Version 2.0.2, Build 2221 Yesterday suddenly a pop-up message appeared on my screen asking me to upgrade to "Ubuntu 14.04 'Trusty Tahr'". I'd also be very happy to upgrade my system to "Ubuntu 14.04 'Trusty Tahr'". Following are the issues about which I'm little bit scared about and I need you all talented people's expert advice/help/suggestions on it: Will upgrading to "Ubuntu 14.04 'Trusty Tahr'" affect the softwares I mentioned above? I mean will I need to re-install/un-install and install these softwares too? Do I really need to and is it really a worth to upgrade to "Ubuntu 14.04 'Trusty Tahr'" from "Ubuntu 12.04 LTS" now? If I upgrade to "Ubuntu 14.04 'Trusty Tahr'" what advantage I'll get from web developer's point of view? Will the upgrade be hassle free and will I be ablr to continue my on-going work without any difficulties? Is "Ubuntu 14.04 'Trusty Tahr'" a LTS version and if yes till when it's going to provide support? These are the five crucial queries I have. If you want any further explanation from me please feel free to ask me. Thanks for spending some of your vaulable time in reading and understanding my issue. Any kind of help/comment/suggestion/answer would be highly appreciated. Though if someone gives canonical, precise and up to the mark answer, it will be of great help to me as well as other web developers using Ubuntu around the world. Once again thank you so much you great people around the globe. Waiting for your precious replies.

• #MIX Day 2 Keynote: Put the Phone Down and Listen

  - by andrewbrust

  MIX day 1’s keynote was all about Windows Phone 7 (WP7).  MIX day 2’s was a reminder that Microsoft has much more going on than a new mobile platform.  Steven Sinofsky, Scott Guthrie, Doug Purdy and others showed us lots of other good things coming from Microsoft, mostly in the developer stack, that we certainly shouldn’t overlook.  These included the forthcoming IE9, its new JavaScript compiling engine and support for HTML 5 that takes full advantage of the local PC resources, including the Graphics Processing Unit.  The announcements also included important additions to ASP.NET (and one subtraction, in the form of lighter-weight ViewState technology) including almost-obsessive jQuery support.  That support is so good that John Resig, creator of the jQuery project, came on stage to tell us so.  Then Scott Guthrie told us that Microsoft would be contributing code to Open Source jQuery project. This is not your father’s Microsoft, it would seem. But to me, the crown jewel in today’s keynote were the numerous announcements around the Open Data Protocol (OData).  OData is nothing more than the protocol side of “Astoria” (now known as WCF Data Services, and until recently called ADO.NET Data Services) separated out and opened up as a platform-neutral standard.  The 2009 Professional Developers Conference (PDC) was Microsoft’s vehicle for first announcing OData, as well as project “Dallas,” an Azure-based cloud platform for publishing commercial OData feeds.  And we had already known about “bridges” for Astoria (and thus OData) for PHP and Java.  We also knew that PowerPivot, Microsoft’s forthcoming self-service BI plug-in for Excel 2010, will consume OData feeds and then facilitate drill-down analysis of their data.  And we recently found out that SQL Reporting Services reports (in the forthcoming SQL Server 2008 R2) and SharePoint 2010 lists will be consumable in OData format as well. So what was left to announce?  How about OData clients for Palm webOS and Apple iPhone/Objective C?  How about the release to Open Source of .NET’s OData client?  Or the ability to publish any SQL Azure database as an OData service by simply checking a checkbox at deployment?  Maybe even a Silverlight tool (code-named “Houston”) to create SQL Azure databases (and then publish them as OData) right in the browser?  And what if you you could get at NetFlix’s entire catalog in OData format?  You can – just go to http://odata.netflix.com/Catalog/ and see for yourself.  Douglas Purdy, who made these announcements said “we want OData to work on as many devices and platforms as possible.”  After all the cross-platform OData announcements made in about a half year’s time, it’s hard to dispute this. When Microsoft plays the data card, and plays it well, watch out, because data programmability is the company’s heritage.  I’ll be discussing OData at length in my April Redmond Review column.  I wrote that column two weeks ago, and was convinced then that OData was a big deal. Today upped the ante even more.  And following the Windows Phone 7 euphoria of yesterday was, I think, smart timing.  The phone, if it’s successful, will be because it’s a good developer platform play.  And developer platforms (as well as their creators) are most successful when they have a good data strategy.  OData is very Silverlight-friendly, and that means it’s WP7-friendly too.  Phone plus service-oriented data is a one-two punch.  A phone platform without data would have been a phone with no signal.

• Install Problem (Ubuntu Server 10.04) with USB as it reboots when I hit 'enter' for 'Install Ubuntu Server' option! Help

  - by Alastair

  We cannot seem to install Ubuntu Server with USB as it reboots when I hit 'enter' for 'Install Ubuntu Server' option. My friend wants to try setting up a server so; we downloaded Ubuntu Server 10.04.4 we created a boot CD and installed ubuntu server no problem at all. But then the problem arose the hardrive we wanted to use is a 1tb sata drive and the computer orginally has 40gb IDE. So I bought a Sata to IDE and IDE to Sata converter from: http://www.microdirect.co.uk/Home/Product/52926/IDE-to-SATA-converter---Converts-IDE-HDD-to-SATA-inc-sata-data-and-power-cables Unfortunately this converter means I cannot plug in the IDE cable meaning I only have one IDE connection i.e CD drive has to be disconnected for the 1tb sata Hardrive to be connected. So now the 1tb drive is connected, powered it on opened the bios to make sure the hdd appeared it did as ST3ASDAPFKG (somthing like that). Fortunately the computer supports USB booting, so I read ubuntu server usb install instructions I tried: Startup Disk Creator & Unebootin Startup Disk Creator made the usb bootable with the 'ubuntu-10.04.4-server-i386.iso' All looked fine stuck the usb drive in, booted the machine up and I am quickly presented with ubuntu language choice. I hit enter to select English then I am presented with: Install Ubuntu Server, Install Ubuntu Enterprise Cloud, Check Disk for defects, test memory, Boot from first hard disk, Rescue a broken system I can move up and down the menu fine everything seems ok, I select 'Install Ubuntu Server', computer just hangs and screen either goes blank or locks. So I rebooted the computer loads the same menus fine, I select 'Install Ubuntu Server' hit 'enter' and the computer just restarts then brings me back to the same menu. hmmm Then I tried choosing the rest of the options separately: Install Ubuntu Server, Install Ubuntu Enterprise Cloud, Check Disk for defects, test memory, Boot from first hard disk, Rescue a broken system computer just restarts and back to the same ubuntu menu every-time. Grrrr At this point I wish I actually new how to command line install or something but I don't have a clue how to do that. So I tried hitting 'f6' for 'other options' and I tried them all in various combinations and individually. No Luck: (Expert mode, acpi=off, noapic, nolapic, edd=on, nodmraid, nomodeset, Free Software only) At this point I am wondering if it is a bios setting causing problems, I tried turning every option in there on off that I don't understand. No Luck. I then discovered by accident if you hit esc in the ubuntu install menu it says "you are leaving the graphical boot menu and starting the text mode interface" I hit 'Ok'. Next a prompt pops up saying 'boot:' One time it responded when I typed somthing with 'Cannot find kernal image (something like that but since then it just restarts when I hit enter in that prompt). I had a browse on the net and found someone suggesting removing quiet from install command for 'Install Ubuntu Server'. Made no difference at all just reboots... Orginal boot options noprompt cdrom-detect/try-usb=true persistent file=/cdrom/preseed/ubuntu-server.seed initrd=/install/initrd.gz quiet -- Modified boot options noprompt cdrom-detect/try-usb=true persistent file=/cdrom/preseed/ubuntu-server.seed initrd=/install/initrd.gz -- Still I cannot install Ubuntu Server by USB as it, reboots when I hit 'enter' for 'Install Ubuntu Server' option. This is a real pain as we cannot take the 1tb Sata Hardrive and swap it for IDE to be able to use the cd drive. Why is is it so hard to install ubuntu server with usb? I have wasted a full day and half on this really frustrated any help would be amazing! I know the answers out there just seems a bit illusive at the moment!

• Plymouth and GRUB do not show at all

  - by WarriorIng64

  I am using Ubuntu 11.04 64-bit as my only OS on my desktop computer, which used to only run Ubuntu 10.04 LTS until I had the time to upgrade it with a fresh install. It uses integrated NVIDIA graphics (listed as a GeForce 6150SE nForce 430 by the NVIDIA X Server Settings utility) with the current proprietary driver as provided by the Additional Drivers utility, and has a VGA connection to a 1680x1050 Acer monitor. I used to get the (ugly-looking version of) Plymouth graphical boot screen while under 10.04. It didn't look that great, but I was fine with it. Now, it doesn't show on 11.04 at all during boot (I just get an error message in a moving gray box from the monitor saying "Input Not Supported"), and only rarely it will show on shutdown, all garbled up. I could not get GRUB to show during boot while holding down Shift, either (same error message), but pressing Enter while it should be up starts the system normally. A picture of the error message I was getting: Once fully booted, the system still shows the login screen and desktop just fine. Any information on how to troubleshoot this would be appreciated. If there's any hardware-specific stuff I forgot to include here, let me know the relevant commands to run in a comment below. Things that I've tried: Running plymouth in a framebuffer: no effect Booting with nomodeset as my grub boot: option no effect Booting with nomodeset and plymouth in a framebuffer: no effect other than Plymouth showing during shutdown only Following the Softpedia instructions for fixing Plymouth's resolution: Problem mostly solved, except logo does not show in Plymouth during boot, and both grub and Plymouth are slightly off-center #4 above, but with nomodeset removed as a grub boot option: same effect as #4 #5 above, but with vt.handoff=7 added as a grub boot option: same effect as #4 I have added the current contents of /etc/default/grub as requested in the comments: # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video=uvesafb:mode_option=1280x1024-24,mtrr=3,scroll=ywrap" GRUB_CMDLINE_LINUX="" # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' GRUB_GFXMODE=1280x1024 # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1" CURRENT STATUS: I forgot to uncomment one line as per "things that I've tried" #4, so I took care of that. I can now see GRUB during startup when I hold Shift and a normal-looking Plymouth during shutdown...but Plymouth during boot is now just a solid purple screen. In each case, it's displayed a little off-center to the left, with a thin black bar running down the right side of the monitor. The error pictured above no longer shows. I'd say this problem is about 2/3 solved now. UPDATE: After Natty started freezing up on me, I decided to dual-boot with Oneiric, which unfortunately shows the same problems. Rather than trying all these workarounds though, I decided to do what I should have done from the start and file a pair of bug reports. LAST UPDATE: Bug 850908 has been confirmed as a legitimate nouveaufb bug. I have overwritten my 11.04 partition with 12.04 LTS, and I can confirm at this time that the issue is present there, as well. I will now flag this question to be closed, yet I hope it was helpful for anyone who experienced similar issues; if you are still having the same problem as me, please go there and mark yourself as affected. Thanks!

• Craig Mundie's video

  - by GGBlogger

  Timothy recently posted “Microsoft Shows Off Radical New UI, Could Be Used In Windows 8” on Slashdot. I took such grave exception to his post that I found it necessary to my senses to write this blog. We need to go back many years to the days of hand cranked calculators and early main frame computers. These devices had singular purposes – they were “number crunchers” used to make accounting easier. The front facing display in early mainframes was “blinken lights.” The calculators did provide printing – in the form of paper tape and the mainframes used line printers to generate reports as needed. We had other metaphors to work with. The typewriter was/is a mechanical device that substitutes for a type setting machine. The originals go back to 1867 and the keyboard layout has remained much the same to this day. In the earlier years the Morse code telegraphs gave way to Teletype machines. The old ASR33, seen on the left in this photo of one of the first computers I help manufacture, used a keyboard very similar to the keyboards in use today. It also generated punched paper tape that we generated to program this computer in machine language. Everything considered this computer which dates back to the late 1960s has a keyboard for input and a roll of paper as output. So in a very rudimentary fashion little has changed. Oh – we didn’t have a mouse! The entire point of this exercise is to point out that we still use very similar methods to get data into and out of a computer regardless of the operating system involved. The Altair, IMSAI, Apple, Commodore and onward to our modern machines changed the hardware that we interfaced to but changed little in the way we input, view and output the results of our computing effort. The mouse made some changes and the advent of windowed interfaces such as Windows and Apple made things somewhat easier for the user. My 4 year old granddaughter plays here Dora games on our computer. She knows how to start programs, use the mouse, play the game and is quite adept so we have come some distance in making computers useable. One of my chief bitches is the constant harangues leveled at Microsoft. Yup – they are a money making organization. You like Apple? No problem for me. I don’t use Apple mostly because I’m comfortable in the Windows environment but probably more because I don’t like Apple’s “Holier than thou” attitude. Some think they do superior things and that’s also fine with me. Obviously the iPhone has not done badly and other Apple products have fared well. But they are expensive. I just build a new machine with 4 Terabytes of storage, an Intel i7 Core 950 processor and 12 GB of RAMIII. It cost me – with dual monitors – less than 2000 dollars. Now to the chief reason for this blog. I’m going to continue developing software for as long as I’m able. For that reason I don’t see my keyboard, mouse and displays changing much for many years. I also don’t think Microsoft is going to spoil that for me by making radical changes to my developer experience. What Craig Mundie does in his video here:  http://www.ispyce.com/2011/02/microsoft-shows-off-radical-new-ui.html is explore the potential future of computer interfaces for the masses of potential users. Using a computer today requires a person to have rudimentary capabilities with keyboards and the mouse. Wouldn’t it be great if all they needed was hand gestures? Although not mentioned it would also be nice if computers responded intelligently to a user’s voice. There is absolutely no argument with the fact that user interaction with these machines is going to change over time. My personal prediction is that it will take years for much of what Craig discusses to come to a cost effective reality but it is certainly coming. I just don’t believe that what Craig discusses will be the future look of a Window 8.

• MySQL is running VERY slow

  - by user1032531

  I have two servers: a VPS and a laptop. I recently re-built both of them, and MySQL is running about 20 times slower on the laptop. Both servers used to run CentOS 5.8 and I think MySQL 5.1, and the laptop used to do great so I do not think it is the hardware. For the VPS, my provider installed CentOS 6.4, and then I installed MySQL 5.1.69 using yum with the CentOS repo. For the laptop, I installed CentOS 6.4 basic server and then installed MySQL 5.1.69 using yum with the CentOS repo. my.cnf for both servers are identical, and I have shown below. For both servers, I've also included below the output from SHOW VARIABLES; as well as output from sysbench, file system information, and cpu information. I have tried adding skip-name-resolve, but it didn't help. The matrix below shows the SHOW VARIABLES output from both servers which is different. Again, MySQL was installed the same way, so I do not know why it is different, but it is and I think this might be why the laptop is executing MySQL so slowly. Why is the laptop running MySQL slowly, and how do I fix it?

• How can I back up my ubuntu system?

  - by Eloff

  I'm sure there's a lot of questions on here similar to this, and I've been reading them, but I still feel this warrants a new question. I want nightly, incremental backups (full disk images would waste a lot of space - unless compressed somehow.) Preferably rotating or deleting old backups when running out of space or after a fixed number of backups. I want to be able to quickly and painlessly restore my system from these backups. This is my first time running ubuntu as my main development machine and I know from my experience with it as a server and in virtual machines that I regularly manage to make it unbootable or damage it to the point of being unable to rescue it. So how would you recommend I do this? There are so many options out there I really don't know where to start. There seems to be a vocal school of thought that it's sufficient to backup your home directory and the list of installed packages from the package manager. I've already installed lots of things from source, or outside of the package manager (development tools, ides, compilers, graphics drivers, etc.) So at the very least, if I do not back up the operating system itself I need to grab all config files, all program binaries, all created but required files, etc. I'd rather backup too much than too little - an ubuntu install is tiny anyway. Also this drastically reduces the restore time, which would cost me more in my time than the extra storage space. I tried using Deja Dup to backup the root partition, excluding some things like /mnt /media /dev /proc etc. Although many websites assured me you can backup a running linux system this way - that seems to be false as it complained that it could not backup the following files: /boot/System.map-3.0.0-17-generic /boot/System.map-3.2.0-22-generic /boot/vmcoreinfo-3.0.0-17-generic /boot/vmlinuz-3.0.0-17-generic /boot/vmlinuz-3.2.0-22-generic /etc/.pwd.lock /etc/NetworkManager/system-connections/LAN Connection /etc/apparmor.d/cache/lightdm-guest-session /etc/apparmor.d/cache/sbin.dhclient /etc/apparmor.d/cache/usr.bin.evince /etc/apparmor.d/cache/usr.lib.telepathy /etc/apparmor.d/cache/usr.sbin.cupsd /etc/apparmor.d/cache/usr.sbin.tcpdump /etc/apt/trustdb.gpg /etc/at.deny /etc/ati/inst_path_default /etc/ati/inst_path_override /etc/chatscripts /etc/cups/ssl /etc/cups/subscriptions.conf /etc/cups/subscriptions.conf.O /etc/default/cacerts /etc/fuse.conf /etc/group- /etc/gshadow /etc/gshadow- /etc/mtab.fuselock /etc/passwd- /etc/ppp/chap-secrets /etc/ppp/pap-secrets /etc/ppp/peers /etc/security/opasswd /etc/shadow /etc/shadow- /etc/ssl/private /etc/sudoers /etc/sudoers.d/README /etc/ufw/after.rules /etc/ufw/after6.rules /etc/ufw/before.rules /etc/ufw/before6.rules /lib/ufw/user.rules /lib/ufw/user6.rules /lost+found /root /run/crond.reboot /run/cups/certs /run/lightdm /run/lock/whoopsie/lock /run/udisks /var/backups/group.bak /var/backups/gshadow.bak /var/backups/passwd.bak /var/backups/shadow.bak /var/cache/apt/archives/lock /var/cache/cups/job.cache /var/cache/cups/job.cache.O /var/cache/cups/ppds.dat /var/cache/debconf/passwords.dat /var/cache/ldconfig /var/cache/lightdm/dmrc /var/crash/_usr_lib_x86_64-linux-gnu_colord_colord.102.crash /var/lib/apt/lists/lock /var/lib/dpkg/lock /var/lib/dpkg/triggers/Lock /var/lib/lightdm /var/lib/mlocate/mlocate.db /var/lib/polkit-1 /var/lib/sudo /var/lib/urandom/random-seed /var/lib/ureadahead/pack /var/lib/ureadahead/run.pack /var/log/btmp /var/log/installer/casper.log /var/log/installer/debug /var/log/installer/partman /var/log/installer/syslog /var/log/installer/version /var/log/lightdm/lightdm.log /var/log/lightdm/x-0-greeter.log /var/log/lightdm/x-0.log /var/log/speech-dispatcher /var/log/upstart/alsa-restore.log /var/log/upstart/alsa-restore.log.1.gz /var/log/upstart/console-setup.log /var/log/upstart/console-setup.log.1.gz /var/log/upstart/container-detect.log /var/log/upstart/container-detect.log.1.gz /var/log/upstart/hybrid-gfx.log /var/log/upstart/hybrid-gfx.log.1.gz /var/log/upstart/modemmanager.log /var/log/upstart/modemmanager.log.1.gz /var/log/upstart/module-init-tools.log /var/log/upstart/module-init-tools.log.1.gz /var/log/upstart/procps-static-network-up.log /var/log/upstart/procps-static-network-up.log.1.gz /var/log/upstart/procps-virtual-filesystems.log /var/log/upstart/procps-virtual-filesystems.log.1.gz /var/log/upstart/rsyslog.log /var/log/upstart/rsyslog.log.1.gz /var/log/upstart/ureadahead.log /var/log/upstart/ureadahead.log.1.gz /var/spool/anacron/cron.daily /var/spool/anacron/cron.monthly /var/spool/anacron/cron.weekly /var/spool/cron/atjobs /var/spool/cron/atspool /var/spool/cron/crontabs /var/spool/cups

• How to detect and configure an output with xrandr?

  - by ysap

  I have a DELL U2410 monitor connected to a Compaq 100B desktop equipped with an integrated AMD/ATI graphics card (AMD E-350). The installed O/S is Ubuntu 10.04 LTS. The computer is connected to the monitor via the DVI connection. The problem is that I cannot set the desktop resolution to the native 1920x1200. The maximum allowed resolution is 1600x1200. Doing some research I found about the xrandr utility. Unfortunately, when trying to use it I cannot configure it to the required resolution. First, it does not report the output name (which supposed to be DVI-0), saying default instead. Without it I cannot use the --fb option. The EDID utility seems to identify the monitor well. Here's the output from get-edid: # EDID version 1 revision 3 Section "Monitor" # Block type: 2:0 3:ff # Block type: 2:0 3:fc Identifier "DELL U2410" VendorName "DEL" ModelName "DELL U2410" # Block type: 2:0 3:ff # Block type: 2:0 3:fc # Block type: 2:0 3:fd HorizSync 30-81 VertRefresh 56-76 # Max dot clock (video bandwidth) 170 MHz # DPMS capabilities: Active off:yes Suspend:yes Standby:yes Mode "1920x1200" # vfreq 59.950Hz, hfreq 74.038kHz DotClock 154.000000 HTimings 1920 1968 2000 2080 VTimings 1200 1203 1209 1235 Flags "-HSync" "+VSync" EndMode # Block type: 2:0 3:ff # Block type: 2:0 3:fc # Block type: 2:0 3:fd EndSection but the xrandr -q command returns: Screen 0: minimum 640 x 400, current 1600 x 1200, maximum 1600 x 1200 default connected 1600x1200+0+0 0mm x 0mm 1600x1200 0.0* 1280x1024 0.0 1152x864 0.0 1024x768 0.0 800x600 0.0 640x480 0.0 720x400 0.0 When I try to set the resolution, I get: $ xrandr --fb 1920x1200 xrandr: screen cannot be larger than 1600x1200 (desired size 1920x1200) $ xrandr --output DVI-0 --auto warning: output DVI-0 not found; ignoring How can I set the screen resolution to 1920x1200? Why doesn't xrandr identify the DVI-0 output? Note that the same computer running Ubuntu version higher than 10.04 detects the correct resolution with no problems. On this machine I cannot upgrade due to some legacy hardware compatibility problems. Also, I don't see any optional screen drivers available in the Hardware Drivers dialog. ---- UPDATE: following the answer to this question, I got some advance. Now the required mode is listed in the xrandr -q list, but I can't switch to that mode. Using the Monitors applet (which now shows the new mode), I get the response that: The selected configuration for displays could not be applied. Could not set the configuration to CRTC 262.

• concurrency::accelerator_view

  - by Daniel Moth

  Overview We saw previously that accelerator represents a target for our C++ AMP computation or memory allocation and that there is a notion of a default accelerator. We ended that post by introducing how one can obtain accelerator_view objects from an accelerator object through the accelerator class's default_view property and the create_view method. The accelerator_view objects can be thought of as handles to an accelerator. You can also construct an accelerator_view given another accelerator_view (through the copy constructor or the assignment operator overload). Speaking of operator overloading, you can also compare (for equality and inequality) two accelerator_view objects between them to determine if they refer to the same underlying accelerator. We'll see later that when we use concurrency::array objects, the allocation of data takes place on an accelerator at array construction time, so there is a constructor overload that accepts an accelerator_view object. We'll also see later that a new concurrency::parallel_for_each function overload can take an accelerator_view object, so it knows on what target to execute the computation (represented by a lambda that the parallel_for_each also accepts). Beyond normal usage, accelerator_view is a quality of service concept that offers isolation to multiple "consumers" of an accelerator. If in your code you are accessing the accelerator from multiple threads (or, in general, from different parts of your app), then you'll want to create separate accelerator_view objects for each thread. flush, wait, and queuing_mode When you create an accelerator_view via the create_view method of the accelerator, you pass in an option of immediate or deferred, which are the two members of the queuing_mode enum. At any point you can access this value from the queuing_mode property of the accelerator_view. When the queuing_mode value is immediate (which is the default), any commands sent to the device such as kernel invocations and data transfers (e.g. parallel_for_each and copy, as we'll see in future posts), will get submitted as soon as the runtime sees fit (that is the definition of immediate). When the value of queuing_mode is deferred, the commands will be batched up. To send all buffered commands to the device for execution, there is a non-blocking flush method that you can call. If you wish to block until all the commands have been sent, there is a wait method you can call. Deferring is a more advanced scenario aimed at performance gains when you are submitting many device commands and you want to avoid the tiny overhead of flushing/submitting each command separately. Querying information Just like accelerator, accelerator_view exposes the is_debug and version properties. In fact, you can always access the accelerator object from the accelerator property on the accelerator_view class to access the accelerator interface we looked at previously. Interop with D3D (aka DX) In a later post I'll show an example of an app that uses C++ AMP to compute data that is used in pixel shaders. In those scenarios, you can benefit by integrating C++ AMP into your graphics pipeline and one of the building blocks for that is being able to use the same device context from both the compute kernel and the other shaders. You can do that by going from accelerator_view to device context (and vice versa), through part of our interop API in amp.h: *get_device, create_accelerator_view. More on those in a later post.

• Validating Petabytes of Data with Regularity and Thoroughness

  - by rickramsey

  by Brian Zents When former Intel CEO Andy Grove said “only the paranoid survive,” he wasn’t necessarily talking about tape storage administrators, but it’s a lesson they’ve learned well. After all, tape storage is the last line of defense to prevent data loss, so tape administrators are extra cautious in making sure their data is secure. Not surprisingly, we are often asked for ways to validate tape media and the files on them. In the past, an administrator could validate the media, but doing so was often tedious or disruptive or both. The debut of the Data Integrity Validation (DIV) and Library Media Validation (LMV) features in the Oracle T10000C drive helped eliminate many of these pains. Also available with the Oracle T10000D drive, these features use hardware-assisted CRC checks that not only ensure the data is written correctly the first time, but also do so much more efficiently. Traditionally, a CRC check takes at least 25 seconds per 4GB file with a 2:1 compression ratio, but the T10000C/D drives can reduce the check to a maximum of nine seconds because the entire check is contained within the drive. No data needs to be sent to a host application. A time savings of at least 64 percent is extremely beneficial over the course of checking an entire 8.5TB T10000D tape. While the DIV and LMV features are better than anything else out there, what storage administrators really need is a way to check petabytes of data with regularity and thoroughness. With the launch of Oracle StorageTek Tape Analytics (STA) 2.0 in April, there is finally a solution that addresses this longstanding need. STA bundles these features into one interface to automate all media validation activities across all Oracle SL3000 and SL8500 tape libraries in an environment. And best of all, the validation process can be associated with the health checks an administrator would be doing already through STA. In fact, STA validates the media based on any of the following policies: Random Selection – Randomly selects media for validation whenever a validation drive in the standalone library or library complex is available. Media Health = Action – Selects media that have had a specified number of successive exchanges resulting in an Exchange Media Health of “Action.” You can specify from one to five exchanges. Media Health = Evaluate – Selects media that have had a specified number of successive exchanges resulting in an Exchange Media Health of “Evaluate.” You can specify from one to five exchanges. Media Health = Monitor – Selects media that have had a specified number of successive exchanges resulting in an Exchange Media Health of “Monitor.” You can specify from one to five exchanges. Extended Period of Non-Use – Selects media that have not had an exchange for a specified number of days. You can specify from 365 to 1,095 days (one to three years). Newly Entered – Selects media that have recently been entered into the library. Bad MIR Detected – Selects media with an exchange resulting in a “Bad MIR Detected” error. A bad media information record (MIR) indicates degraded high-speed access on the media. To avoid disrupting host operations, an administrator designates certain drives for media validation operations. If a host requests a file from media currently being validated, the host’s request takes priority. To ensure that the administrator really knows it is the media that is bad, as opposed to the drive, STA includes drive calibration and qualification features. In addition, validation requests can be re-prioritized or cancelled as needed. To ensure that a specific tape isn’t validated too often, STA prevents a tape from being validated twice within 24 hours via one of the policies described above. A tape can be validated more often if the administrator manually initiates the validation. When the validations are complete, STA reports the results. STA does not report simply a “good” or “bad” status. It also reports if media is even degraded so the administrator can migrate the data before there is a true failure. From that point, the administrators’ paranoia is relieved, as they have the necessary information to make a sound decision about the health of the tapes in their environment.

• Windows Azure Use Case: New Development

  - by BuckWoody

  This is one in a series of posts on when and where to use a distributed architecture design in your organization's computing needs. You can find the main post here: http://blogs.msdn.com/b/buckwoody/archive/2011/01/18/windows-azure-and-sql-azure-use-cases.aspx Description: Computing platforms evolve over time. Originally computers were directed by hardware wiring - that, the “code” was the path of the wiring that directed an electrical signal from one component to another, or in some cases a physical switch controlled the path. From there software was developed, first in a very low machine language, then when compilers were created, computer languages could more closely mimic written statements. These language statements can be compiled into the lower-level machine language still used by computers today. Microprocessors replaced logic circuits, sometimes with fewer instructions (Reduced Instruction Set Computing, RISC) and sometimes with more instructions (Complex Instruction Set Computing, CISC). The reason this history is important is that along each technology advancement, computer code has adapted. Writing software for a RISC architecture is significantly different than developing for a CISC architecture. And moving to a Distributed Architecture like Windows Azure also has specific implementation details that our code must follow. But why make a change? As I’ve described, we need to make the change to our code to follow advances in technology. There’s no point in change for its own sake, but as a new paradigm offers benefits to our users, it’s important for us to leverage those benefits where it makes sense. That’s most often done in new development projects. It’s a far simpler task to take a new project and adapt it to Windows Azure than to try and retrofit older code designed in a previous computing environment. We can still use the same coding languages (.NET, Java, C++) to write code for Windows Azure, but we need to think about the architecture of that code on a new project so that it runs in the most efficient, cost-effective way in a Distributed Architecture. As we receive new requests from the organization for new projects, a distributed architecture paradigm belongs in the decision matrix for the platform target. Implementation: When you are designing new applications for Windows Azure (or any distributed architecture) there are many important details to consider. But at the risk of over-simplification, there are three main concepts to learn and architect within the new code: Stateless Programming - Stateless program is a prime concept within distributed architectures. Rather than each server owning the complete processing cycle, the information from an operation that needs to be retained (the “state”) should be persisted to another location c(like storage) common to all machines involved in the process.  An interesting learning process for Stateless Programming (although not unique to this language type) is to learn Functional Programming. Server-Side Processing - Along with developing using a Stateless Design, the closer you can locate the code processing to the data, the less expensive and faster the code will run. When you control the network layer, this is less important, since you can send vast amounts of data between the server and client, allowing the client to perform processing. In a distributed architecture, you don’t always own the network, so it’s performance is unpredictable. Also, you may not be able to control the platform the user is on (such as a smartphone, PC or tablet), so it’s imperative to deliver only results and graphical elements where possible.  Token-Based Authentication - Also called “Claims-Based Authorization”, this code practice means instead of allowing a user to log on once and then running code in that context, a more granular level of security is used. A “token” or “claim”, often represented as a Certificate, is sent along for a series or even one request. In other words, every call to the code is authenticated against the token, rather than allowing a user free reign within the code call. While this is more work initially, it can bring a greater level of security, and it is far more resilient to disconnections.

• Installing CUDA on Ubuntu 12.04 with nvidia driver 295.59

  - by johnmcd

  I have been trying to get cuda to run on a nvidia gt 650m based laptop. I am running Ubuntu 12.04 with the nvidia 295.59 driver. Also, my laptop uses Optimus so I have install the driver via bumblebee. Bumblebee is not working correctly yet -- however I believe it is possible to install CUDA independently. To install CUDA I have followed the instructions detailed here: How can I get nVidia CUDA or OpenCL working on a laptop with nVidia discrete card/Intel Integrated Graphics? However I am still running into problem building the sdk.

• OpenGL slower than Canvas

  - by VanDir

  Up to 3 days ago I used a Canvas in a SurfaceView to do all the graphics operations but now I switched to OpenGL because my game went from 60FPS to 30/45 with the increase of the sprites in some levels. However, I find myself disappointed because OpenGL now reaches around 40/50 FPS at all levels. Surely (I hope) I'm doing something wrong. How can I increase the performance at stable 60FPS? My game is pretty simple and I can not believe that it is impossible to reach them. I use 2D sprite texture applied to a square for all the objects. I use a transparent GLSurfaceView, the real background is applied in a ImageView behind the GLSurfaceView. Some code public MyGLSurfaceView(Context context, AttributeSet attrs) { super(context); setZOrderOnTop(true); setEGLConfigChooser(8, 8, 8, 8, 0, 0); getHolder().setFormat(PixelFormat.RGBA_8888); mRenderer = new ClearRenderer(getContext()); setRenderer(mRenderer); setLongClickable(true); setFocusable(true); } public void onSurfaceCreated(final GL10 gl, EGLConfig config) { gl.glEnable(GL10.GL_TEXTURE_2D); gl.glShadeModel(GL10.GL_SMOOTH); gl.glDisable(GL10.GL_DEPTH_TEST); gl.glDepthMask(false); gl.glEnable(GL10.GL_ALPHA_TEST); gl.glAlphaFunc(GL10.GL_GREATER, 0); gl.glEnable(GL10.GL_BLEND); gl.glBlendFunc(GL10.GL_ONE, GL10.GL_ONE_MINUS_SRC_ALPHA); gl.glHint(GL10.GL_PERSPECTIVE_CORRECTION_HINT, GL10.GL_NICEST); } public void onSurfaceChanged(GL10 gl, int width, int height) { gl.glViewport(0, 0, width, height); gl.glMatrixMode(GL10.GL_PROJECTION); gl.glLoadIdentity(); gl.glOrthof(0, width, height, 0, -1f, 1f); gl.glMatrixMode(GL10.GL_MODELVIEW); gl.glLoadIdentity(); } public void onDrawFrame(GL10 gl) { gl.glClear(GL10.GL_COLOR_BUFFER_BIT); gl.glMatrixMode(GL10.GL_MODELVIEW); gl.glLoadIdentity(); gl.glEnableClientState(GL10.GL_VERTEX_ARRAY); gl.glEnableClientState(GL10.GL_TEXTURE_COORD_ARRAY); // Draw all the graphic object. for (byte i = 0; i < mGame.numberOfObjects(); i++){ mGame.getObject(i).draw(gl); } // Disable the client state before leaving gl.glDisableClientState(GL10.GL_VERTEX_ARRAY); gl.glDisableClientState(GL10.GL_TEXTURE_COORD_ARRAY); } mGame.getObject(i).draw(gl) is for all the objects like this: /* HERE there is always a translatef and scalef transformation and sometimes rotatef */ gl.glBindTexture(GL10.GL_TEXTURE_2D, mTexPointer[0]); // Point to our vertex buffer gl.glVertexPointer(3, GL10.GL_FLOAT, 0, mVertexBuffer); gl.glTexCoordPointer(2, GL10.GL_FLOAT, 0, mTextureBuffer); // Draw the vertices as triangle strip gl.glDrawArrays(GL10.GL_TRIANGLE_STRIP, 0, mVertices.length / 3); EDIT: After some test it seems to be due to the transparent GLSurfaceView. If I delete this line of code: setEGLConfigChooser(8, 8, 8, 8, 0, 0); the background becomes all black but I reach 60 fps. What can I do?

• Merge sort versus quick sort performance

  - by Giorgio

  I have implemented merge sort and quick sort using C (GCC 4.4.3 on Ubuntu 10.04 running on a 4 GB RAM laptop with an Intel DUO CPU at 2GHz) and I wanted to compare the performance of the two algorithms. The prototypes of the sorting functions are: void merge_sort(const char **lines, int start, int end); void quick_sort(const char **lines, int start, int end); i.e. both take an array of pointers to strings and sort the elements with index i : start <= i <= end. I have produced some files containing random strings with length on average 4.5 characters. The test files range from 100 lines to 10000000 lines. I was a bit surprised by the results because, even though I know that merge sort has complexity O(n log(n)) while quick sort is O(n^2), I have often read that on average quick sort should be as fast as merge sort. However, my results are the following. Up to 10000 strings, both algorithms perform equally well. For 10000 strings, both require about 0.007 seconds. For 100000 strings, merge sort is slightly faster with 0.095 s against 0.121 s. For 1000000 strings merge sort takes 1.287 s against 5.233 s of quick sort. For 5000000 strings merge sort takes 7.582 s against 118.240 s of quick sort. For 10000000 strings merge sort takes 16.305 s against 1202.918 s of quick sort. So my question is: are my results as expected, meaning that quick sort is comparable in speed to merge sort for small inputs but, as the size of the input data grows, the fact that its complexity is quadratic will become evident? Here is a sketch of what I did. In the merge sort implementation, the partitioning consists in calling merge sort recursively, i.e. merge_sort(lines, start, (start + end) / 2); merge_sort(lines, 1 + (start + end) / 2, end); Merging of the two sorted sub-array is performed by reading the data from the array lines and writing it to a global temporary array of pointers (this global array is allocate only once). After each merge the pointers are copied back to the original array. So the strings are stored once but I need twice as much memory for the pointers. For quick sort, the partition function chooses the last element of the array to sort as the pivot and scans the previous elements in one loop. After it has produced a partition of the type start ... {elements <= pivot} ... pivotIndex ... {elements > pivot} ... end it calls itself recursively: quick_sort(lines, start, pivotIndex - 1); quick_sort(lines, pivotIndex + 1, end); Note that this quick sort implementation sorts the array in-place and does not require additional memory, therefore it is more memory efficient than the merge sort implementation. So my question is: is there a better way to implement quick sort that is worthwhile trying out? If I improve the quick sort implementation and perform more tests on different data sets (computing the average of the running times on different data sets) can I expect a better performance of quick sort wrt merge sort? EDIT Thank you for your answers. My implementation is in-place and is based on the pseudo-code I have found on wikipedia in Section In-place version: function partition(array, 'left', 'right', 'pivotIndex') where I choose the last element in the range to be sorted as a pivot, i.e. pivotIndex := right. I have checked the code over and over again and it seems correct to me. In order to rule out the case that I am using the wrong implementation I have uploaded the source code on github (in case you would like to take a look at it). Your answers seem to suggest that I am using the wrong test data. I will look into it and try out different test data sets. I will report as soon as I have some results.

• Windows Azure Use Case: New Development

  - by BuckWoody

  This is one in a series of posts on when and where to use a distributed architecture design in your organization's computing needs. You can find the main post here: http://blogs.msdn.com/b/buckwoody/archive/2011/01/18/windows-azure-and-sql-azure-use-cases.aspx Description: Computing platforms evolve over time. Originally computers were directed by hardware wiring - that, the “code” was the path of the wiring that directed an electrical signal from one component to another, or in some cases a physical switch controlled the path. From there software was developed, first in a very low machine language, then when compilers were created, computer languages could more closely mimic written statements. These language statements can be compiled into the lower-level machine language still used by computers today. Microprocessors replaced logic circuits, sometimes with fewer instructions (Reduced Instruction Set Computing, RISC) and sometimes with more instructions (Complex Instruction Set Computing, CISC). The reason this history is important is that along each technology advancement, computer code has adapted. Writing software for a RISC architecture is significantly different than developing for a CISC architecture. And moving to a Distributed Architecture like Windows Azure also has specific implementation details that our code must follow. But why make a change? As I’ve described, we need to make the change to our code to follow advances in technology. There’s no point in change for its own sake, but as a new paradigm offers benefits to our users, it’s important for us to leverage those benefits where it makes sense. That’s most often done in new development projects. It’s a far simpler task to take a new project and adapt it to Windows Azure than to try and retrofit older code designed in a previous computing environment. We can still use the same coding languages (.NET, Java, C++) to write code for Windows Azure, but we need to think about the architecture of that code on a new project so that it runs in the most efficient, cost-effective way in a Distributed Architecture. As we receive new requests from the organization for new projects, a distributed architecture paradigm belongs in the decision matrix for the platform target. Implementation: When you are designing new applications for Windows Azure (or any distributed architecture) there are many important details to consider. But at the risk of over-simplification, there are three main concepts to learn and architect within the new code: Stateless Programming - Stateless program is a prime concept within distributed architectures. Rather than each server owning the complete processing cycle, the information from an operation that needs to be retained (the “state”) should be persisted to another location c(like storage) common to all machines involved in the process.  An interesting learning process for Stateless Programming (although not unique to this language type) is to learn Functional Programming. Server-Side Processing - Along with developing using a Stateless Design, the closer you can locate the code processing to the data, the less expensive and faster the code will run. When you control the network layer, this is less important, since you can send vast amounts of data between the server and client, allowing the client to perform processing. In a distributed architecture, you don’t always own the network, so it’s performance is unpredictable. Also, you may not be able to control the platform the user is on (such as a smartphone, PC or tablet), so it’s imperative to deliver only results and graphical elements where possible.  Token-Based Authentication - Also called “Claims-Based Authorization”, this code practice means instead of allowing a user to log on once and then running code in that context, a more granular level of security is used. A “token” or “claim”, often represented as a Certificate, is sent along for a series or even one request. In other words, every call to the code is authenticated against the token, rather than allowing a user free reign within the code call. While this is more work initially, it can bring a greater level of security, and it is far more resilient to disconnections.

• MySQL is running VERY slow on CentOS 6x (not 5x)

  - by user1032531

  I have two servers: a VPS and a laptop. I recently re-built both of them, and MySQL is running about 20 times slower on the laptop. Both servers used to run CentOS 5.8 and I think MySQL 5.1, and the laptop used to do great so I do not think it is the hardware. For the VPS, my provider installed CentOS 6.4, and then I installed MySQL 5.1.69 using yum with the CentOS repo. For the laptop, I installed CentOS 6.4 basic server and then installed MySQL 5.1.69 using yum with the CentOS repo. my.cnf for both servers are identical, and I have shown below. For both servers, I've also included below the output from SHOW VARIABLES; as well as output from sysbench, file system information, and cpu information. I have tried adding skip-name-resolve, but it didn't help. The matrix below shows the SHOW VARIABLES output from both servers which is different. Again, MySQL was installed the same way, so I do not know why it is different, but it is and I think this might be why the laptop is executing MySQL so slowly. Why is the laptop running MySQL slowly, and how do I fix it?

• SFML fail to load image as texture

  - by zyeek

  I have come to a problem with the code below ... Using SFML 2.0 #include <SFML/Graphics.hpp> #include <iostream> #include <list> int main() { float speed = 5.0f; // create the window sf::RenderWindow window(sf::VideoMode(sf::VideoMode::getDesktopMode().height - 300, 800), "Bricks"); // Set game window position on the screen window.setPosition( sf::Vector2i(sf::VideoMode::getDesktopMode().width/4 + sf::VideoMode::getDesktopMode().width/16 , 0) ); // Allow library to accept repeatitive key presses (i.e. holding key) window.setKeyRepeatEnabled(true); // Hide mouse cursor //window.setMouseCursorVisible(false); // Limit 30 frames per sec; the minimum for all games window.setFramerateLimit(30); sf::Texture texture; if (!texture.loadFromFile("tile.png", sf::IntRect(0, 0, 125, 32))) { std::cout<<"Could not load image\n"; return -1; } // Empty list of sprites std::list<sf::Sprite> spriteContainer; bool gameFocus = true; // run the program as long as the window is open while (window.isOpen()) { sf::Vector2i mousePos = sf::Mouse::getPosition(window); // check all the window's events that were triggered since the last iteration of the loop sf::Event event; while (window.pollEvent(event)) { float offsetX = 0.0f, offsetY = 0.0f; if(event.type == sf::Event::GainedFocus) gameFocus = !gameFocus; else if(event.type == sf::Event::LostFocus) gameFocus = !gameFocus; if(event.type == sf::Event::KeyPressed) { if (event.key.code == sf::Keyboard::Space) { if(gameFocus) { // Create sprite and add features before putting it into container sf::Sprite sprite(texture); sprite.scale(.9f,.7f); sf::Vector2u textSize = texture.getSize(); sprite.setPosition(sf::Vector2f(mousePos.x-textSize.x/2.0f, mousePos.y - textSize.y/2.0f)); spriteContainer.push_front(sprite); } } if(event.key.code == sf::Keyboard::P) std::cout << spriteContainer.size() << std::endl; if( event.key.code == sf::Keyboard::W ) offsetY -= speed; if( event.key.code == sf::Keyboard::A ) offsetX -= speed; if( event.key.code == sf::Keyboard::S ) offsetY += speed; if( event.key.code == sf::Keyboard::D ) offsetX += speed; } // "close requested" event: we close the window if (event.type == sf::Event::Closed || event.key.code == sf::Keyboard::Escape) window.close(); // Move all sprites synchronously for (std::list<sf::Sprite>::iterator sprite = spriteContainer.begin(); sprite != spriteContainer.end(); ++sprite) sprite->move(offsetX, offsetY); //sprite.move(offsetX,offsetY); } // clear the window with black color window.clear(sf::Color::Black); // draw everything here... // window.draw(...); // Draw all sprites in the container for (std::list<sf::Sprite>::iterator sprite = spriteContainer.begin(); sprite != spriteContainer.end(); ++sprite) window.draw(*sprite); // end the current frame window.display(); } return 0; } A couple weeks ago it worked flawlessly to my expectation, but now that I come back to it and I am having problems importing the image as a texture "tile.png". I don't understand why this is evening happening and the only message I get via the terminal is "Cannot load image ..." then a bunch of random characters. My libraries are for sure working, but now I am not sure why the image is not loading. My image is in the same directory as with my .h and .cpp files. This is an irritating problem that keep coming up for some reason and is always a problem to fix it. I import my libraries via my own directory "locals" which contain many APIs, but I specifically get SFML, and done appropriately as I am able to open a window and many other stuff.
