New blog – cyberorg.wordpress.com

August 29th, 2017 by

I have not been actively participating in openSUSE project for some time now, as a result there has not been much to blog about on openSUSE Lizards blog, there is a new blog at https://cyberorg.wordpress.com to blog about what I have been and will be up to with Li-f-e: Linux for Education project among other things. I am also now “Member Emeritus” of the openSUSE community due to lack of participation, so cyberorg@opensuse.org email address will no longer work, please use @cyberorg.info if you need to get in touch with me.

After almost a decade of bringing you Li-f-e: Linux for Education based on openSUSE, it is now based on Ubuntu MATE LTS releases. I hope to provide the same excellent user experience that you have come to expect. Download it from here. Reason for this change is mentioned in previous post and it’s discussion(lack of interest/time/skills by anyone for maintaining live installer). You can of course easily enable Education Build Service repository to install packages on standard openSUSE or use susestudio to create your own spin with Education packages.

To new beginnings…

Future of Li-f-e: Linux for Education distribution

July 4th, 2016 by

We have come a long way since the first Li-f-e live media based on openSUSE was created, the current release is based on openSUSE Leap 42.1. Deployments by Indonesia’s education system is a shining example of openSUSE Education project’s accomplishment.

The openSUSE project has stopped producing live medias for Leap and also live-installer is dropped from live medias created for the Tumbleweed distribution. As Li-f-e is primarily a live distribution we would not be able to create any more medias without live-installer. So unless this situation changes we may not have Li-f-e based on Leap 42.2.

In the meantime I’ve had a look at Ubuntu to create Li-f-e based on the latest LTS release of Ubuntu-Mate, check it out here. Software selection available is kept identical to the Li-f-e based on openSUSE, however there is always a room for improvement, suggestions to enhance it are always welcome.

Many thanks to openSUSE/SUSE who willing to become one of the sponsor for this event. I organized some friends from Indonesia openSUSE community to make an openSUSE booth. We prepare several PC and RasPi for some demo and displaying openSUSE 13.2. I really appreciate the help from Andi Sugandi, Yan Arief Purwanto, and Adnan Kurniawan for their time in this event. Joey Li from SUSE Taiwan, Max Huang from Taiwan openSUSE community and Bin Li from China openSUSE community, also came and joint us on the event.

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.

History

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.

LTSP client goes Banana Pi!

The Raspberry Pi is a credit-card sized computer running ARM processor that plugs into your TV/PC monitor, mouse and a keyboard, it is capable of running Linux and can be made to do many interesting things.The Banana Pi is a what Chinese ingeniousness came up with after they checked out Raspberry Pi, they made a lot more powerful knockoff. This is a “How-to” use Banana Pi as LTSP client. (more…)
