  • mysqld - master to slave replication using rsync innodb, sequence number issues

    - by Luis
    I've read several of the related topics posted here, but I have not been able to avoid this innodb error. The steps I've taken to replicate data from a Slackware server - 5.5.27-log (S) to a FreeBSD slave - 5.5.21-log (F) were these: (S) flush tables with read lock; (S) in another terminal show master status; (S) stop mysqld via command line in third terminal; (F) while both servers are stopped, rsync mysql datadir from (S), excluding master.info, mysql-bin and relay-* files; (F) start mysqld (skip-slave) 121018 12:03:29 InnoDB: Error: page 7 log sequence number 456388912904 InnoDB: is in the future! Current system log sequence number 453905468629. InnoDB: Your database may be corrupt or you may have copied the InnoDB InnoDB: tablespace but not the InnoDB log files. See InnoDB: http://dev.mysql.com/doc/refman/5.5/en/forcing-innodb-recovery.html InnoDB: for more information. This kind of error happens for a lot of tables. I know I can use dump, but the database is large, ca. 70GB and the systems are slow (old), so would like to get this replication to work with data transfer. What should I try to solve this issue?

  • attempted WUBI install corrupted Vista

    - by oliver zimmermann
    Tried to install WUBI through Google Chrome on my Vista machine. Got through the usual warning about running new software, selected "continue" and waited for a prompt about where to install WUBI. Never got one...waited about 30 minutes (computer still running fine)...decided to reboot and try again. OOOOOPS. Was not able to reboot Vista. Ouch. When I run a Vista recovery CD it tells me there is an "X:" drive on what used to be my C: drive and it cannot find a Vista install to recover. Anyone seen this ? It is making me very happy... THANKS!!!!!!!!!!!!

  • What is the mentally retirement age as a programmer? [closed]

    - by Yau Leung
    Here in my city, computer science is still a relatively "young" degree started at most 20-30 years ago. So most of the "senior programmers" here are at most 40 years old. I have friends in London in their mid 40s are earning decent salaries by working for investment banks on various financial products. Some of them don't want to get "promoted" as project managers because they still have the passion in coding and they are probably making more money by coding. However, when you get older, you might loss creativity and might not unable to pick up new languages or frameworsk as fast as those who are decades younger than us. For those who are unwilling or unable to be migrated to be project managers. What should be the mentally retirement age?

  • How to install ubuntu from desktop w/o internet access?

    - by Tom P.
    I am trying to install ubuntu on a netbook without a CD drive. I first attempted a flash drive, but it did not work, so I decided to use the flash drive to transfer the application that can install from the desktop. However, this is a secondhand school computer that needs its borderline spyware security suite wiped before it can access the internet, so I cannot use the install from desktop application. Do I have any other options? I do have access to an external CD drive that I could try, but I am unconvinced that I would get different results since it would have to go through a USB port. Any and all input is very much appreciated!

  • Cannot see user desktop (Applications, Places, System...) when I log in

    - by Jesi
    I am very new to Ubuntu. I recently got a new laptop running Windows 7. I am using Virtual Box and just installed the Ubuntu 12.10 ISO as a new Virtual Machine within Virtual Box. Everything seemed to install just fine and I even added the Guest Additions under Devices. The problem is that I cannot see the menus and my login information. The virtual machine says it is running; however, I do not have the Applications, Places, System, etc. tray to select from. Is there something I am supposed to do after logging in to get this? I entered my password and everything seemed fine, I just don't have those drop-down menus available...

  • Couldnt find a way to open blender software

    - by sapphirebox001
    I am new to Ubuntu. I downloaded the latest version of Blender (2.70a) from official blender.org site as an tar.bz2 file. My Ubuntu OS is 14.04 LTS amd64 bit os, and I am sure that I have downloaded the correct version of blender. I have read that for security reasons, Ubuntu does not allow executing exe files. Since the downloaded package contains blender as an executable/x-executable type, it is not able to execute. I do not have an internet connection in that computer too. Also the "Allow executing file as program" checkbox is checked by default. Still double clicking it does not execute the file. Can anyone say how to open this file? P.S: Wine also checked but requires active internet connection, which I dont have.

  • Issues with upgrade to ubuntu 14.04

    - by SUBPUR
    First, I should say that I am a total beginner. When answering, please do not take for granted that I understand even the most basic step. Now for my question: Yesterday, I was given the option to update to ubuntu 14.04. I clicked yes, and the system took about 2.5 hours to accomplish this task. Now, whenever I log into my user account, I get an error message and then I am asked to authenticate my user account. When I try to enter the password, my computer freezes. Please help, what can I do to fix this?

  • 2D Game Development dynamics in c++ [on hold]

    - by novice
    I am new to developing computer graphic applications in c++ using OpenGl. I want to develop games but I really am facing problems when it comes to understanding concepts like trajectory, collisions, gravity and also the use of various physics engines that are available. when i search the internet I kind of get lost because they aren't for beginners like me. There is some hardcore mathematics, physics and coding involved. I need to pick the concepts that are mostly needed in game dev like trajectory, collision etc. Any good tutorials that can help me out in picking these concepts from the start.

    I have an acer aspire running net book remix 11.10. the mouse pad freezes up completely and I must use an external mouse. if I reboot the computer the mouse pad will work again. i seem to have this problem happen in the middle of either using firefox or a few time while using thunderbird. anyone else having this problem. an external mouse works but scrolling is choppy or it scrolls part of the way down a page and then jumps to the top again. I don't recall having this problem after upgrading to 11.10 so I think it is related to an update. my Linux skills are limited.

  • How do I get Bibletime 2.91 running on 12.04?

    - by To Do
    I would like to install the latest version of Bibletime (2.9.1) on my computer because the version in the official repositories (2.8.1) has a bug with the "Mag" feature. I had installed 2.9.1 on 12.04 32 bit through one of the following ppa's: ppa:pkgcrosswire/ppa ppa:pkgcrosswire/developer-testing Now on an Ubuntu 12.04.1 64 bit, I'm getting a dependency issue. It seems that it depends on libsword8 but it should actually depend on libsword9 which is available in the repositories. See http://sword-dev.350566.n4.nabble.com/Ubuntu-12-04-td4577002.html Can someone help me install this app please? EDIT: apt-get install -f bibletime yields the following: The following packages have unmet dependencies: bibletime : Depends: libsword8 (>= 1.6.2+dfsg) but it is not installable Depends: bibletime-data (= 2.9.1-0ubuntu0~r70~precise1) but 2.9.1-1~ppa2~precise is to be installed E: Unable to correct problems, you have held broken packages.

  • error when installing rmagic gem on Ubuntu 12.04 for Ruby on Rails

    - by PeaceDefender
    0 down vote favorite I am trying to get my Ruby on Rails application working and installing RMagic gem. But I get an error that says "Can't install RMagick 2.13.1. Can't find the ImageMagick library or one of the dependent libraries." Altough I have ImageMagick installed with its dependences. Terminal log : http://pastebin.com/vcgkbwZR I even tried to installed RMagic from Synaptic, but I get the same error when I run "bundle" command. Through my search, some people had problem with lib dependencies, but I believed I have them all installed. Another solution I found is this ( error installing RMagick from gem ) a little bit old and not sure if it is going to work for 12.04. BUT, I don't know where those configurations should go.

  • "Sorry, Ubuntu 12.04 has experienced an internal error."

    - by malapradej
    I have recently upgraded to Precise and had some errors. It seems to be quite random and with differences in the error reports. I have duly sent the reports hoping the system will have found the problem and sorted itself out. After the second error I am following the wizards (software...) advice and seeking help. The 1st time it happened I jotted down the following: ExecutablePath /usr/lib/tracker/tracker-extract LaunchPad bug 950765 AMD64 The second time the following: ExecutablePath /usr/share/appart/appart-gpu-error-intel.py "Possible GPU hang........" sandybridge-m-gt2 LaunchPad bug 981261 If there is anyone that can help it is much appreciated. I did not really want to upgrade at this stage, but was forced to due to the latest version of python-numpy in precise. You win some, you loose some.... Jacques I am using a Pavilion dv6 notebook and 64bit ubuntu 12.04 LTS

  • Video Bug in Ubuntu 12.10 MSI CX623 laptop

    - by user104731
    http://www.youtube.com/watch?v=5xyJkS8XjgA&feature=youtu.be I managed to take a video with what happens on my Ubuntu 12.10 laptop when I play with the volume and hover with the mouse over the slider and when I press Ctrl + Alt + D (show Desktop/minimize all) The real bugs are those in which the panel becomes transparent on the down side, exactly above the volume slider (and not only when that slider appears, but also when brightness slider appears, and when blocking my touchpad applet appears) and when I have a maximized window, more maximized windows or a non maximized window that touches the panel, while I use Ctrl+Alt+D (show Desktop/hide all normal windows). Is there a way to solve this bug? PS: The other bugs are from Record My Desktop. I didn't have the mentioned bugs in ubuntu 12.04, but I like more the graphics in 12.10.

  • Grub Doesn't Load after Update

    - by Parris
    Hi Everyone, After I updated ubuntu (I believe it was most likely a kernel update) and restarted I selected ubuntu from the windows boot loader (I am using wubi). At this point I would usually land on the grub loader; however, I see something about NTFS file not found and a couple other screens flash then the computer restarts. I have tried pressing ESC right after to try and get some options, but I think grub is just not found or something... Not sure what is going on.. Any help would be much appreciated :). Thanks!

  • WCF RIA Services - Hands On Lab

    At the keynote for the Silverlight 4 Launch alongside Scott Guthrie I demonstrated (minute 28 to minute 38) how to build a Silverlight 4 application using WCF RIA Services and the new Visual Studio 2010 tooling. The application I built is an online book store to rival the big boys OK, well, maybe not the big boys but you get the idea. As promised I am elaborating on the presentation and breaking down the steps to create the application here.

  • Implementing scrolling buttons in android

    - by Twirling Hearth
    I want to create an Android app in which the buttons scroll up or down the screen, kind of like a "wheel", so that when the "last" button is reached, it is simply followed seamlessly by the first one. I would want it to look something like the Price Is Right wheel. (This video at 0:12.) I want the first round of buttons to be presented for the user to tap the screen and make his choice, which would lead to a second round of buttons based on the first choice, and a third round based on the second choice. I've done a number of different google searches, but nothing so far. Any ideas?

  • How to operating systems… run… without having an OS to run in?

    - by Plazmotech Binary
    I'm really curious right now. I'm a Python programmer, and this question just boggled me: You write an OS. How do you run it? It has to be run somehow, and that way is within another OS? How can an application run without being in an OS? How do you tell the computer to run, say, C, and execute these commands to the screen, if it doesn't have an OS to run in? Does it have to do with a UNIX kernel? If so, what is a unix kernel, or a kernel in general? I'm sure OSes are more complicated than that, but how does it work? It would be really brilliant to know this! Thanks.

  • Outbound ports to allow through firewall

    - by dunxd
    This question was asked before, but in a rather general way. I'm asking more specifically based on my current requirements. We have a number of remote offices made up of a bunch of PCs and an ASA 5505 which is used as firewall and VPN termination point. In the offices we share the internet connection with one or more other organisations over whom we have very little control, asides from the config on the ASAs. For a bunch of reasons I'd like to lock down these ASA 5505s to only allow outbound traffic to ports used by applications we know we need. I'm putting a standard config to roll out to all the ASAs, and if we need to open up ports for the other orgs we can do it on request. But I want to leave open the most commonly required ports so we can get up and running without waiting on other folks technical staff to get back. I plan to allow the following TCP ports to support commonly required resources: POP3 (110 and 995) HTTP (80 and 443) IMAP4 (143 and 993) SMTP (25 and and 465) The question really is, what other ports do I need to leave open to allow for "normal" working. I've seen UDP port 53 for DNS as one. Are there any others that would be worth opening up? Just to note - I'll also be setting up monitoring systems to keep an eye on the ports we do allow. Any of the above could be misused of course. We'll also back all this up with signed agreements. But I'm aiming for a technical solutions where I don't have to start out with the full requirements of everyone we share connections with. See also: outbound ports that are always open

  • System doesn't show option to select operating system during startup!

    - by samsher
    i am new at linux and ubuntu, today i installed ubuntu 12.04 but during installation some problem happened, i don't remember what was that exactly (but can tell you that it was related to boot), so i reinstalled ubuntu (using usb stick both time) and ubuntu installation finished successfully, Now problem is that when I start my computer then system is directly selecting ubuntu as my operating system, i have installed it along with windows 7 in option during installation, so it should give me option to select which operating system i want to use. I don't know what may be the problem. Also, I want to know where ubuntu is installed (which directory)? i just selected default setting during installation as i am noob in these things.

  • where is my disk space?

    - by user166241
    I recently had a problem with .xsession-errors file - it became very big ( 90GB) and took all disk space: How I can check what takes disk space in /tmp?. I cleaned it with command > .xsession-errors but after an hour it became large again. So I deleted it (rm .xsession-errors) - it helped because it wasn't recreated but again after hour disk space disappeared - now there is no .xsession-errors anymore but I don't know where is the memory: df Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda1 106640456 101223392 4 100% / udev 8166744 8 8166736 1% /dev tmpfs 3270224 972 3269252 1% /run none 5120 0 5120 0% /run/lock none 8175552 152 8175400 1% /run/shm du -sc * .[^.]* | sort -n 0 initrd.img 0 initrd.img.old 0 proc 0 sys 0 vmlinuz 0 vmlinuz.old 4 cdrom 4 lib64 4 media 4 mnt 4 selinux 8 dev 12 srv 16 lost+found 68 tmp 1124 run 3396 lib32 5164 .rpmdb 5540 root 8888 sbin 9120 bin 17132 etc 106080 opt 116956 boot 861908 lib 3530584 usr 3821836 var 13371260 home 21859112 total So there is around 100GB used but executing du -sc * .[^.]* | sort -n in root directory finds only ~21 GB - so what takes 80GB?? How to check it? I suspect that when I deleted the `.xsession-errors' file the errors were redirected somwhere else - but where?

  • Can't interact with windows after first login

    - by evilpie
    Every time I restart my computer and login into my ubuntu account for the first time, I can't click on anything besides the bar on the left. So I can start Firefox from there, but I am not able to click on the new tab button etc. Same will all other apps. I can start the Terminal via the keyboard, but I can't move it around. So I have to logout via the keyboard and login again. Usually everything works fine now. Just waiting doesn't help. The only obvious change I made to Ubuntu was to move the /home directory.

  • Laptop suspend appears broken, what must I roll back?

    - by M. Tibbits
    Question: What package contains the subprogram responsible for the KMenu option "sleep"? Background: I've been running KUbuntu 10.04.1 and I am completely updated. Recently (within the past month), the "sleep" menu item has stopped working. It just sits there waiting like I clicked nothing. I've check all of the logs in /var/log and nothing is added when I click sleep. I'm guessing that something I updated has bollux'ed things up, but I don't know which package contains the component that I need to roll back. In the meantime, I've installed uswsusp, but s2ram & s2both don't ask my password when the laptop resumes -- which really bothers me. So now that I've got a little time to track this down, I had to post -- any ideas??

  • Microsoft Secret Event: New Tablet Unveiling?

    If you read the headline, you know what everyone thinks it will be: a new tablet computer, that Microsoft will manufacture from beginning to end. Apparently, the company believes it will be better able to compete against Apple if it controls both the hardware and the software. But why choose this location for the announcement? Wired thinks it makes sense if the tablet features Xbox live streaming. That would turn the humble device into something of a media machine. Speaking of the device itself, what kind of specs will this hypothetical tablet have? It's hard to say. Microsoft boasts software...
