Code quality and Code guidelines
February 19th, 2014 by Tuukka PasanenToday I like to take you precious time to talk about thing that get so less attention in open source world. I like to talk little bit about QA and Coding guidelines.
Many reader who are in companies that take care of themselves or are involved some major open source or free software project like KDE, GNOME or Linux kernel knows that they/we have Coding guidelines. KDE have it here and Kernel have it here. So they have them and whats the big deal? (more…)
Elfcloud.fi a small cloud storage that could
February 13th, 2014 by Tuukka PasanenI’ve been seeking cloud storage of my life for long time now. My needs are not much (but most of the time they are too big as I have learned) only space and if possible Linux/Mac OS X FUSE for using service.
Service being open source or not isn’t such big thing in this case. How data is stored (crypted or not) and how can I get them out there if I need them is what I treasure most.
I have tested SpiderOak, Wuala, Dropbox and box.net but non of them fits for my needs perfectly. As I want to use these services with Linux all of them have Linux clients and most of them have FUSE-filesystem. Lately I have been using Wuala but it has problem that FUSE stuff is written in Java (it works under openSUSE just fine!). With GUI it’s clean and like said works very well but then comes but if you don’t want to use GUI you are in little bit trouble. It’s supported but I haven’t got it working. Xvfb comes to rescue but still it’s not really a solution!
When I heard about Elfcloud.fi I though okay we have some storage provider in Finland no big deal. I just popped their web site and noticed that they are really open source friendly company. They have Github Python-library (Apache Version 2.0 licensed) and full API documentation which is dead simple JSON stuff also their pricing scheme ain’t that bad. I have mention that this is hardcore crypto cloud service. If you lose your key you can wave goodbye to you data. Best of all they gonna have marvelous FUSE implementation as I’m writing it currently (They also have C++ library available on request. Apache Version 2.0 licensed of course).
So if you want to keep your data on Europe and have it stored in same country that have also is also trusted by Google datacenters and Microsoft you can check out elfcloud.fi. It’s not for everyone for sure but those who are in same need place to store data without hustle this can be the stuff for you.
You can download python API RPM from here: http://download.opensuse.org/repositories/home:/illuusio:/elfcloud/
How to destroy your data from harddisk permamently?
January 24th, 2014 by Tuukka PasanenFirst warning and please read it: If you wipe your harddisk, USB-stick or Flash with any of these tips. Your data won’t magically come back! After correct ‘secure rm’ or ‘NWipe’ there way is no way to bring your valuable data back. Make backups and happy wiping!
Destroying data permanently from hard disk is not as easy as you think. Sometime hard disks just self destructs without notice but when there is police behind you door knocking and you have destroy as much data as you can it’s little bit trickier. Even normal cases when there ain’t police at door and you just want to make sure that your old hard disk is clean and it doesn’t contain your personal data it’s a bit of a problem. (more…)
openSUSE and GCC part 10: Distributing to other distributions than openSUSE with OBS
January 7th, 2014 by Tuukka PasanenLast time I talked about OBS and how to compile your application that you have developed with GCC. OBS is much more than just a tool for compiling openSUSE additional packages. You can also compile Debian, Ubuntu, Arch and Fedora (and couple more) but why on earth you want to do that? Short answer: because you can! Little bit longer answer: because you can and freedom is two way road. You can’t guess what Linux distribution or OS your user wants to use but you can make sure that you application is first class citizen in that Linux distribution. (more…)
Enter UnReal World RPG
December 19th, 2013 by Tuukka PasanenWhen I was kid Commodore 64 was big thing and I played ‘Gateway to Apshai‘ hour after hour. It really hit me. Others liked Ultimas but ‘Gateway to Apshai’ was THE thing to me. Years after C64 was gone with the wind I found world of Rogue, Omega and Nethack. Sweetest of them was Omega. Omega’s World map was big and you could do what ever you like and wander around and you didn’t have to fight all the time. As this was a long, long time ago none of those games are no more in active development but Sami Maaranen is still developing unique northern hemisphere survival game called UnReal World RPG.

openSUSE and GCC part 9: Open Build Service why should I use it?
December 11th, 2013 by Tuukka PasanenImagine yourself in place where: you have succeeded to create best open source project ever appeared in face of earth. Your project has most fabulous source management system ever imagined (mostly coded by you) and you release tar balls often with plenty new neat features. You have managed that your project users provide some binary builds for Windows, Mac OS X and some bunch of Linux distributions. So your ride is smooth and pleasant (Mr. Maslow just waves to you from bottom of pyramid). Then black clouds arise and some Linux build manager who is doing binary builds for spefic important Linux distribution just vanishes upon the earth or you notice it would be nice to support more wide range of distributions than you allready have. Then you should consider using Open Build Service or openSUSE version of it known as OBS. (more…)
openSUSE and GCC part 8: RPMs and how to write them
December 3rd, 2013 by Tuukka PasanenIt seems this it’s already 8 of this 10 part series of using GCC with openSUSE. This time topic is: RPM. RPM started as Redhat Package Manager and then it involved to RPM package manager (self explaining acronym like GNU). RPM packages are just files containing all the needed stuff to install application, font or something else in to openSUSE system. (more…)
