I can code with javascript and I’m fairly good at it (not marvelous just brialiant!). If you have read some of my resent blog post I think in C/C++/Perl or Bash. I also have some kind of a hobby to help out with UnReal world RPG game. Mostly my part is to make it work with *nix platform (mainly Linux and Mac OS X).
As we have seen world is moving fast forward towards web. It’s the-place-to-be for everyone. There is huge potential for players just wandering around and yelling for pleasure to play UrW! So I thought let’s see if we could port SDL to javascript/Flash or something straight from same source. after tiny amount of searching I popped up Emscripten. (more…)

Is my server alive and how good is my connection
March 10th, 2014 by Tuukka PasanenIf you have time to setup real solution and need something reliable test Zabbix (http://zabbix.com). Zabbix is wonderful all in one solutions for monitoring network and your hosts (servers). If you are in need of knowing how good you Internet/(W)LAN connections is then things are getting complicated. (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 4: Pkg-config and what one can do with it
October 28th, 2013 by Tuukka PasanenWhen 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…)
openSUSE and GCC part 2: compiling ‘Hello World’
October 15th, 2013 by Tuukka PasanenI really hope you readied last article ‘OpenSUSE and GCC part 1: getting started‘ or you understand basics and you have GCC (Only GNU C Compiler as GCC stands Gnu Compiler Collection) installed. This time we learn how to compile application called ‘Hello World’. It’s so popular application even wikipedia have article about it. (more…)

Welcome to the Indian Reservation, Ubuntu GNOMEs!
March 12th, 2013 by Will StephensonI read today that Ubuntu-Gnome is now an official flavour of Ubuntu! Great work, you’ve achieved the same level of recognition as KDE has. Establishing Kubuntu, and other flavours of Ubuntu, was a very canny move on Canonical’s part to control and contain dissent within the Ubuntu big tent. The Kum-ba-ya, lets-all-make-a-circle-in-our-vests hype that Ubuntu generated in 2005 was so strong that it sucked in KDE users as well as users of GNOME, then the anointed Ubuntu desktop. Pretty soon they formed an unofficial forum, in Germany (where else) and started talking about a KDE Fork. The answer from Canonical was to throw them Kubuntu, with “infrastructure and support benefits“, hiring the Debian KDE maintainer, and to pour blandishments into the credulous ears of the KDE leadership of that time, who were mighty unsettled by the acquisition of their then-darling distribution by Novell and its earlier Ximian purchase. This sackful of glass beads and liquor was sufficient to prevent ornery KDE users roaming all over the place doing what they liked, and especially not over the border to other distributions, and in doing so increase Ubuntu’s momentum.
Now fast forward to 2013 and we’re seeing the same happen to GNOME. No longer the standard desktop, but still with significant suction among Ubuntu users, GNOME is neatly herded on to the reservation and congratulated on its wise decision. Now look to your Kubuntu colleagues to see how that is going to work out for you down the road. PS: If Mark promises to install GNOME Ubuntu, don’t believe him for a second. He has an office by now full of desktop computers representing official flavours that he never turns on. Sound familiar?
OT: Shimano Alfine 11 Di2 SEIS and backwards compatibility with existing hubs
October 17th, 2012 by Will StephensonThis post is completely OT for openSUSE, but I don’t have a better place to put it to share this useful snippet of information.
Shimano has just released its electronic shifting system for Alfine internally geared hubs. In mechanical Alfine, the gear cable pull is translated into rotation and gear selection by a detachable unit that sits on the end of the hub. Alfine Di2 SEIS replaces this with a MU-S705 motor unit controlled by an electronic brake lever. But it also introduces a new hub (SG-S705). I wondered whether the motor unit can be retrofitted to existing hubs, as I have the original Alfine 11 (SG-S700) on my Genesis Day One, and I’m not completely happy with the Versa drop bar brake lever integrated shifter*.
So I mailed Paul Lange, Shimano’s German distributor, to ask. The answer I got is that the SG-S700 hub can not be used with the Di2 components, because it has a return spring for upshifts, whereas SG-S705 does not since the gear selection in both directions is actively performed by the motor. If you put a MU-S705 motor unit on an SG-S700 it would be working against the return spring.
As far as I understood it, there is a spring in the SM-S700 cable end unit – I didn’t know there is also one in the hub itself, but I’ll check next time I have the wheel out. Until then, my dreams of perfect drop bar shifting are just that, because at 400 quid SRP the hub is a big investment. Maybe Shimano will take pity on me and make a mechanical STI…
* Mostly because there is no little cam decoupling the upshift lever from the cable spool inside the Versa shifter, so sometimes it shifts up several gears at once.
Editing KIWI configurations with Emacs
August 31st, 2012 by Togan MuftuogluI recently decided to do all my work in emacs and even though the learning speed is a bit slow, I thought I would share what I discoverd regarding editing the KIWI config files. Kiwi has the schema file for the elements and their attributes but unfortunately by default Emacs is unaware of it’s schema location. So first create a schema location file as below and save it.
<locatingRules xmlns="http://thaiopensource.com/ns/locating-rules/1.0">
<transformURI fromPattern="*.xml" toPattern="*.rnc"/>
<uri pattern=”*.kiwi” typeId=”KIWI”/>
<typeId id=”KIWI” uri=”/usr/share/kiwi/modules/KIWISchema.rnc”/>
</locatingRules>
I saved it as $HOME/.emacs.d/data/myschemas.xml. Now add this to your Emac’s init file for autoloading the nxml mode for kiwi files in addition to the xml files
(setq auto-mode-alist
(cons '("\\.\\(xml\\|kiwi\\|xsl\\|rng\\|xhtml\\)\\'" . nxml-mode)
auto-mode-alist))
and add this code for nxml mode to locate the kiwi schema file when you edit a kiwi config file
(eval-after-load 'rng-loc
'(add-to-list 'rng-schema-locating-files (concat user-emacs-directory "data/myschemas.xml")))
Now have fun with Emacs, Kiwi and your openSUSE
