Percona XtraDB | Johan Hedberg
http://johan.pp.se/2012/10/31/percona-xtradb
Random notes of geeky stuff. Posted on October 31, 2012. I've been using standard MySQL with semi-synchronous. On a few places for quite some time and have found it unreliable and as expected a bit slower than a single MySQL instance. So I've been looking for alternatives and after some googling I decided to try out Percona. Or more precisely their XtraDB Clustering software. I've set up two servers in a redundant multi-master manner. Both are virtual machines. Filed under: General geeky.
Installing Steam on Linux Mint 13 | Johan Hedberg
http://johan.pp.se/2013/01/03/installing-steam-on-linux-mint-13
Random notes of geeky stuff. Installing Steam on Linux Mint 13. Posted on January 3, 2013. Today I've went through the hassle of installing steam on Linux Mint 13 (Maya). It wasn't that straightforward, because the guides that exists. Are horribly wrong and for example the ones I tried to follow will make you end up with API version mismatch between Nvidia kernel module and X11 driver. So I'm providing correct and up to date instructions here. You can start by downloading the steam package. Then you'll n...

Random notes of geeky stuff. This is my collection of configuration files for the applications I use on the command line. It includes my favorite shell, favorite editors, favorite terminal multiplexer etc. I mostly keep this for myself for when I install a new server or get a new shell account on someone else's server, but feel free to grab whatever you want from here. I will comment the files some day. Hardstatus string '%{= kG}[ %{G}%H %{g}][%= %{= kw}%? G}][%{B} %d %M %Y %{W}%c:%s %{g}]%{-}'. Bindkey ...

Dogs never bite me. Just humans. Augusti 17th, 2014. För några veckor sen sökte jag ett jobb som Black Jack-dealer, och jag fick det! Just nu går jag en kurs så jag ska lära mig, men det dröjer inte länge tills jag ska vara ute själv! Det kommer klirra lite i kassan iallafall och jag kommer förhoppningsvis ha riktigt kul!

ZFS - Zettabyte File System
http://www.zfs.se/backups
Backing up ZFS storage. ZFS has bultin snapshot functionality which is very useful for taking backups. Taking backups for keeping locally is very simple. You create a snapshot with the zfs. Command and then you're done. Snapshots can be destroyed using the zfs. Command. The data in a snapshot is readonly, and can be accessed using a special directory entry. Zfs snapshot storage/myfs@my-snapshot-name cd /storage/myfs/.zfs/snapshot ls # my-snapshot-name zfs destroy storage/myfs@my-snapshot-name. Which simp...
ZFS - Zettabyte File System
http://www.zfs.se/monitoring
Proper monitoring is almost as important as backups. You want to know when something bad happens, and you want to know it fast so that you may fix it. You will probably have to write some scripts in order to incorporate this into your monitoring system of choice. But for the ZFS part of the setup there's two things you want to look at. Pool and device status. You want to make sure your pool is healty, that no disks are. Created by: Johan Hedberg.

ZFS - Zettabyte File System
http://www.zfs.se/create
Create ZFS pools and file systems. Creating ZFS pools and filesystems is dead easy. You need to have a list of the disks you want to use at hand. This is operating system dependant and not shown. I will assume you know how to list the disks on your operating system. A zfs pool is made up of one or more. Which is kind of a logical group of disks. A vdev can be a single disk, but it's not recommended. Common choices are. Creating a ZFS pool. Created by: Johan Hedberg.
ZFS - Zettabyte File System
http://www.zfs.se/get
The best choice for running any kind of ZFS solution as ZFS is builtin, even the root filesystem runs on ZFS by default. Oracle Solaris is also always on the latest version of ZFS as long as you update. Because you do have valid certificates in your pkg right? So instead we install the native ZFS kernel module from zfsonlinux.org. But using a ppa in order to have proper package management with APT. Apt-add-repository -y ppa:zfs-native/stable apt-get update apt-get -y install ubuntu-zfs modprobe zfs.
ZFS - Zettabyte File System
http://www.zfs.se/maintain
Maintaining ZFS pools and filesystems. Maintaining ZFS is pretty easy as the zpool and zfs commandline utilities are very easy to use and well documented, both with builtin help texts and in the man pages. There's also a ton of useful documentation on Oracle's web pages. Zpool add storage mirror /dev/sdf /dev/sdg. ZFS has support for hotspares which ZFS can automatically use to replace disks that suddenly disappears. Spares unlike vdevs can be added or removed at any time. If you have had a hotspare auto...

Random notes of geeky stuff. Posted on March 23, 2015. A few months ago I moved all my sites out of a shared hosting environment (which I used due to laziness) and onto a VM in order to have some more freedom. I've sticked with Apache instead of switching to Nginx as I work with a huge Apache environment and it's only good to use that same skill-set privately too. (Although I do run nginx on some other boxes for other stuff too of course.). Back to web development. Posted on March 22, 2015. IFA IN6 (.

26 juni 2012 - Montevideo. Hallo, hallo, hierbij het laatste (sniksnik) reisverhaal. De nacht zijn we in Salto gebleven. Ook hier was het weer een praktische opzet, want de busterminaal, de bank met ATM, wisselkantoor, de supermarkt en overige winkels bij elkaar. Verrassend en erg makkelijk. Juist, badderen in de thermobaden. Lekker lui en daarnaast een beetje barbecueën en lanterfanten. Niks mis mee. Uruguay is qua landschap niet zo spectaculair. Het is licht glooiend, soms wat heuvelachtig, met voo...
