How To Get Superbly Hinted Fonts in openSUSE 13.2

May 10th, 2015 by

Hey geekos,

So, this has been kind of my obsession these past years using openSUSE – I couldn’t get the fonts to be gently hinted in the way I want them to be. Every patch or repo had an issue with displaying a specific group of fonts. Now I finally found a way to get my fonts to look like this:

Font hinting


Ever wanted to be a Dj with open source touch?

April 29th, 2015 by

There are plenty of Dj software available on Internet. Most popular I think are Traktor and VirtualDJ. Those are no brainier to choose and don’t support Linux. Because I’m old fart and I started doing my dang long time a go with Technics vinyl-players (and still play my gigs with them). They work as they have always worked great but I though that I need new geeky Dj system with digital vinyls because many interesting release doesn’t do vinyls anymore and I don’t like CD-format. Summarizing all of that I wanted something that what is open source and I can still attach my digital vinyls to it (so it should work with Serato or Traktor vinyls).

Linux audio library smackdown part4: LibAO

March 2nd, 2015 by

Last time I’ve took look at Simple Direct Layer and how to get audio out of it. If SDL still feels little bit too hard to cope with I think I have solutions for you: libAO. Besides being no brainier with API libAO provides huge list of supported operating systems.
There is so much audio systems supported that you won’t be dissapointed but as much as I like everyone use Roaraudio. I don’t see it’s happening really soon (sorry roar you had your time in fame) but supporting Roaraudio  doesn’t mean that libAO is obsolete. It’s far from being obsolete. Libao supports OSS, ALSA and Pulseaudio out of the box and only problem is license is GPL 2.0+ so it’s no-go for proprietary development.


LibAO is developed under Xiph umbrella. Xiph is the organization who brought you Ogg/Vorbis, FLAC, Theora and currently they are hammering together next generation video codec Daala. Opus-audio codec standard is also Xiph project. LibAO rised from Xiph’s need multi-platform audio output library for Vorbis-audio codec. In this point if you don’t have any glue what I just said in last sentences I think you should take your spoon and start shovelling about Open Source audio codecs.
Becaus of the history libAO only has output mode and doesn’t use any callbacks. It doesn’t have fancy Float32 mode (as much as I understood) but that doesn’t say it’s bad thing. It works as expected you just feed bytes and after while you hear them from your speakers.

What about API

Supported outputs: Alsa, Oss, Jack, Mac OS X, Windows
License: GNU General Public license 2.0+

As said libAO API is difficult to describe since there almost ain’t NAN of it. You initialize, ask output device, put in your mode settings and start feeding data. Pulseaudio simple is almost easy as this but it’s still more difficult if you compare it to libAO. LibAO doesn’t support recording so only output and there must be a way to use another device than default but it’s not very easy to find or I was too lazy to dig it out.

So who wants to use libAO? People in hurry and don’t mind GPL-license, someone with very very tiny need of just getting audio out and people how hate bloat.

Summary: So if you hate bloat and again license doesn’t make you unhappy please use this library. Still libAO has kind of same problem that ALSA has. It’s mature, usable and ready for hardcore torturing but is it sexy? No! Is fresh? No, No! Is something that will change it API every week or hour?

After this I have to choose what to bring next. I have FFmpeg, Gstreamer and VLC in row. If you have opinion about next framework let me know.

Linux audio library smackdown part2: Pulseaudio

January 27th, 2015 by

Oh yes.. those were great times! Open Sound System was rocking my Linux based sound system and I was having a time of my life. Like we all know good doesn’t last long. Soon after happiness I find out that OSS couldn’t do recording and playing (full duplex) same time. Fiery same time this was working on Windows 98 very well. I was shocked how the heck my Linux box is so borked? Luckily times were changing and this time they formed only better. ALSA was about to take over OSS in Kernel version 2.6. Why I’m talking about ALSA and OSS when I should talk about Pulseaudio?

It’s hoolihoolihooliday and what fun I can do?

December 16th, 2014 by

I know I’m old losah! Nowadays it’s all about pads, phones and mobile this and mobile that. Install some cool stuff from app store and start mangling. I was amused how much you can do with these small entertainment units but then comes small detail that is not that cool over 20% stuff that is downloaded from Apple store is games and those neat utilities are just 5%. I don’t know what education means but it’s after games so I think it’s good thing. What I’m trying to say stop playing for a while (it’s good thing to do. Don’t get me wrong), put pad/phone down and look around what kind of world we are living in 2014.

Nah Open Source/Free Software doesn’t matter anyway

In year 2014 wasn’t just year on Linux getting into you hands as Android. It was strange year in Linux land. Probably biggest Linux hater from Redmond that called Linux Cancer said ‘hey Free Software and Open Source are cool! We take cherrys like Apple and sell them to you in nice package and there nothing wrong with that (And I’m with them.. it’s what they can do if you buy it)’. Small IoT (Internet-Of-Things, Industrial Internet or choose your favorite term) ARM SOC boards are so Nineties. MIPS made proud comeback! Once it was SGI’s own bitch but now there is growing mass of small very cheap wireless boards started to flow in. All supporting Linux and most have also Android. Targeted to next big thing that you are doing when not playing.

In Finland where I’m located this have been year of economical rumble (read economical crash). Mass layoffs, industrial work places are getting rare and Nokia was sold to that huge firm from Redmond. Selling Nokia out was end of Finland’s mobile dreams as they now have new tablet and fear not also Jolla is launching their new shiny Sailfish tablet and got very good funding through indie-go-go. Ok nobody really wants this tablet because of Android but it’s good to see there is guys and girls that still think with punk attitude and believe that very small firm like Jolla can produce something that big players can’t.

Year 2014 also was big climate is changing year. USA and China make promise to cut their carbon dioxide emission till 2030. USA will do something and China says their peak will be 2030. Does this stop global warming probably not but at least now it’s official that climate is changing. How this is relevant with Linux? Most of these calculation are done in ‘super computers’ and those run tadaaaa… Linux. They don’t run Fedora or openSUSE because they are mostly very fast calculators but they run Linux kernel and something that as immortals never will know because most of them doesn’t calculate climate change things. They calculate nuclear war scenarios. Hello Dr. Falken shall we play a game? Linux++ and HP Machine anyone?

Firefox which is now 10 years old. They broke up with Google because as you can see they don’t need that search flow anymore. Firefox preset for searching in USA is now Yahoo, Russian Yandex and China Baidu. Mozilla also made bold moves with Firefox OS in 2014. More phones and if you need low end cheap phone so you should consider Firefox OS phone 25$ that is very cheap.

So what happened in Linux land

openSUSE made only one release 13.2 but then rumbled big changes in. openSUSE is also catching up popular rolling release method like Arch Linux with Tumbleweed but this year openSUSE upstream Factory also become a rolling release and then it get together with Tumbleweed. It’s good thing! Really things get tested and traditional releases are more stable. Hooray for that. There was and gigantic war against systemd and you can start sending me millions of hate mails for a start because I Like it! It’s modern and does everything that was wrong with Linux init. No more big tune this tune that complex learn curve up to your a** stuff very neat simple configuration. Ok it’s bloat.. but why don’t you start hating Linux kernel. It’s not very UNIX nether it’s doesn’t just one thing like BSD micro-kernel approach. But that is what I wanted to say about that. If you fork Debian just to have Sysvinit I think you are little bit over reacting but best luck to you I’m nothing but thumbs up get it rolling! At the end this feels like Pulseaudio hating campaign. Everybody hated it first but now nobody even notices that they are using it.

Also it becomes clear 2014 that Desktop Linux will never come. Time just passed by and people moved to other things and we have desktop Linux Google’s Chromebooks. In year 2014 It also becomes clear that nor Tizen or Ubuntu phone will be huge success at least it takes little bit longer. My hope is that X will die in great crash of meteorite or let me rephrase how about Wayland project will never take X-windows place and things never become sweet again. Canonical  shiny move with Mir display server will shake things up if it becomes successful. Time will tell how things end up will Mir be successor of X or should it be Wayland?

So what to give as present if you want to give Linux based device?

There is so many Linux gift list to choose from that I just link to them so you can choose from yourself.

This was how I see year 2014. Let’s meet interesting year 2015 which is just few weeks away and light will come back and darkness fade away.

UnReal World RPG and propiertary applications in linux ecosystem part SDL2

November 14th, 2014 by

So last time I was on top of Curl and what problems can come out when you are using it through out different distributions. After that struggle UnReal World RPG have been ported to SDL2. It’s used by Steam so it should we available every distribution you can dream of. How wrong I can be and how correct I am! (more…)

Javascript tools in openSUSE round 1: JSHint

July 2nd, 2014 by

Node.js is not getting as much attention in openSUSE community as it’s gaining foot in development world.  Node.js is not just fancy buzz word that I just to be couple years back. There is plethora of libraries and tools that you can use for Node.js development or web-coding. I have been in this Nnode.js dependency hell (ok you can use npm if you like but if you like to make RPM-files you are in trouble) for a while but now I figured out most troubles and start using new tools! I copied most Node.js packaging stuff from Fedora as like Java Javascript is first class citizen of their ecosystem. I also added packages that were missing and updated and added and updated.

Disable firefox addon compatibility check after update

June 1st, 2014 by

Running this command before launching firefox after update will disable the pesky addon compatibility check at start.

sed -i -e "s@lastAppVersion\", \".*@lastAppVersion\", \"$(rpm -q --queryformat %{VERSION} MozillaFirefox)\"\)\;@" ~/.mozilla/firefox/*/prefs.js

LXQT is ready for testing

May 15th, 2014 by

The stable branch of LXQT, the QT branch of LXDE is now available for openSUSE:13.1 and openSUSE:Factory.
Following are a few screenshots of lxqt, which will be quite familiar to any of you that dabbled with Razor-qt in the past.

Here is the Main Desktop (note, this is using the “flat” theme, and the default openbox windowmanager)

LXQT can offer a fully composited desktop, through the compton compositor, and includes a GUI tool for configuring.

Resulting in a highly configurable composited desktop:

LXQT also provides a powerful configuration tool, which allows you to tweak things the way you like…

So if you’re looking for something to try out, please, give it a shot.

Please keep in mind, we are considering this a “Beta” quality release, so there are still some rough edges.

Additionally, lxqt is currently un-branded for openSUSE, so I certainly wouldn’t turn down help from folks that are into helping out with that sort of thing.

Stable packages are available for openSUSE:13.1(i586, x86_64, armv6l and armv7l) and openSUSE:Factory (i586 and x86_64) at:

Unstable Packages (latest git pulls), are available for 13.1 and Factory, i586 at:

And if you happen to be running Fedora, i586 and x86_64 packages are available at:

Have some fun today… compile kernel

April 15th, 2014 by

Are you bored or seeking something to do? Do you want to do something that your friends will call just waste of time but it is so highly nerdy and most cool? Do you want to know what makes openSUSE or Linux in general tick? (more…)
