How to destroy your data from harddisk permamently?

January 24th, 2014 by

First 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

Last 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

When 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

Imagine 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

It 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…)

openSUSE and GCC part 7: autotools and how I do it

November 19th, 2013 by

Last time I was little bit too hard to autotools. Okay they are not easy but they work. I also let last time people to figure how to get a long with autotools. Now I show how I do it. (more…)

openSUSE and GCC part 6: Introduction to autotools

November 12th, 2013 by

Autotools, autotools and once again autotools. Years ago I started with autotools I thought, ‘Hey someone has really get into linking and compiling’. I was sold for a while and tried to learn it inside out. Then I understood that I will never be good at autotools (So I started to go to gym instead). M4 macro language it is not my thing.
It’s just something that should be put on one way Mars shuttle and send to gray ones to figure out. I think mr. Spock’s brains functioned with M4 but mine won’t. If there is some M4 specialist. Send me e-mail or post comment about it and tell why M4 is best macro language on earth. If nobody stands up for poor M4-macro language I’ll keep unloving it. I can start liking it because I was so wrong with Rexx. (more…)

openSUSE and GCC part 4: Pkg-config and what one can do with it

October 28th, 2013 by

When I re-booted my blogging habits with very UN-sexy and technical topic ‘GNU C Compiler and how to make it with openSUSE’. I thought nobody bothers to read these because A) Everyone who reads openSUSE blogs are PRO B) everyone wants to do Javascript, Python or ‘Put your script language here not C. I can tell actually C ain’t that bad you just have to shoot yourself to leg and then learn how to walk again.
Last blog entry was about ‘openSUSE and GCC part 3: RPM devel packages‘ someone (thanks for pointing that out really!) noted that I should fix C-Code example I was stunned! There were someone that really readied blog entry. Okay he/she didn’t say did he/she like it but some one read it.
I have one real reason to this blog-stuff. I hope I have found something like this when I young and I was starting my journey in Linux land. Currently there is so many more people now in populating it and it’s coming up fast. So If you find errors or don’t understand something be welcome to ask or want to know about something specific let me know! Now we get on today’s topic that is ‘pkg-config and what one can do with it’. (more…)
