This is a follow-up on my earlier post on zypper tab-completion.
Completion for package-names just made its way into git (thus soon will appear in Factory aka Tumbleweed) after ~6 weeks of back and forth exploring different approaches.
And it is super-fast 🙂
If you do not want to wait, you can use OneClickInstallCLI http://multiymp.zq1.de/zypp:Head/zypper
with allowing some vendor changes for libzypp and libsolv
Today I spent some hours implementing nice tab-completion for zypper. There was already a lot done 6 years ago, but the part about installing/removing packages was missing.
Now the thinking part is about the speed. For the tab-completion I needed a list of installed packages and of course we have that in our RPM database (using berkeley DB as a backend). However querying the list with rpm -qa already took over a second on a modern and fast system. On my poor netbook with a cold cache, it took 25 seconds (5 secs on second try with hot cache)… And the point is that you probably do not want to wait 5 seconds for your tab-completion to react.
So to avoid this problem, I used caching via make to produce a better format (plain text). This is then post-processed with sed in a fraction of a second – a speedup factor somewhere between 15 and 150. This makes a big difference.
In the end, I still wonder why plain text is so much faster than a DB. I guess, one reason is that the DB is optimized for retrieval of single values – e.g. rpm -q bash – this is very fast (but even there an egrep “^bash-[^-]+-[^-]+$” is more than twice as fast).
I still want to optimize zypper for better speed, so that a search might some day return in under 2 seconds. One idea for that is to not parse all those config+repo files every time, but only when they change. It could use mmaped files under /var/cache/zypp* as memory to store the binary representations. Though it might become complicated, if dynamic structures such as linked lists are involved.
The future will be interesting…
Hi Geekos, here a small summary of our Thursday February 19th openSUSE miniSummit event here at SCale 13x.
Located in Century AB room, a 80 seats room. The average attendance rate was varying between 50% and 85%.
Qualifying the attendance 50% or more were not related to SUSE / openSUSE, which was a good experience of question and feedback.
The day started by a talk about openSUSE / SUSE Xen and openstack by Peter Linnel and Russel Pavlicek.
One hour later Manu Gupta has presented all the bolts and nuts about GSOC at openSUSE.
We then go for lunch, and corridor exchanges.
I’ve opened the afternoon with my talk “them + me = we” about breaking mythic frontier
Then just after a small break, Mark Fasheh member of filesystem SUSE Labs group has talk about the project Duperemove: dedupe on btrfs (have a look on github the source are there, and package available on obs)
The day continue with a Town Hall talk co-animated by myself and Peter running an open discussion with attendees. With interesting remarks and feedback from openSUSE users, and also complete foreigners. For example, the way systemd was introduced in openSUSE distribution was appreciated (having choice during 2 versions). It was an unstressfull, open and positive exchange.
To follow, Bryan Lunduke and Peter animated a talk about “the 10 things you would love about SUSE and openSUSE if you only you knew…”
I did really enjoy the way they numbered the slides …
Freschy, punchy, funky, the kinda talk I would like to see again at OSC15.
To finalize the day, Markus Feilner for Linux Magazine (de) talked about openQA.
I found interesting the perfect mix we’ve done between openSUSE and SUSE during this day, confirming the excellent partnership we have.
Let the sponsors of this day be warmly thanked to make it happened.

Stay tuned for more news during this week-end.
Again this year the thirteen annual Southern California Linux Expo is in the starting block.
During 3 days you will be able to visit us at our booth (38,39,40).
Yeah 3 booths cause we co-run the KDE and Gnome booth.
The exhibition hall open Friday afternoon at 2pm.
Drew and Peter are working as daemon to get everything ready to spread, Doug have brought also quite numerous goodies there. I will do my best to inform you here or follow my G+ channel
Whatever the way you come, bring your feet there and shake hands.
On Thursday, no one has to miss our full day of openSUSE mini-summit, room Century AB.
There will be interesting talks and also a full green hallway, We’re looking forward SUSE’s team, working together in this promising adventure.
On our side Geeko is ready to cross 9.000 kilometers tomorrow.
Hey cool first time in the famous Airbus A380…
Demo laptop with Tumbleweed and KF5 is also secured.
See you all in Los Angeles
Hello Geekos.
I’m contacting you personally, as an openSUSE Board member.
You certainly already know that we want to have a kicking openSUSE conference next 1st-4th May 2015 at the Haag (NL).
Thus I’ve found that creating special workshop organized by development project could foster our beloved distribution.
oSC is the unique case in the year, where Geekos from all around the world meet together.
Let’s imagine you, meeting perhaps for the first time your fellows, having nice discussions, and hacking around the software you maintain.
There’s high level of chance to meet also your end users, and have constructive exchanges.
That’s why I invite you to propose a workshop directly to our event tools:
https://events.opensuse.org/conference/osc15/proposal
Having a workshop run like a mini-hack sprint, would help any of us in the distribution and the project.
Be it like learn people how to submit nice package, how to do maintenance, or how to do bug triage.
I feel confident that you will have the creative approach to resolve your own problematic.
The event place has small rooms for unattended sessions and they could be used to extend your workshop to get some more work done.
Some practical aspects:
oSC website : https://events.opensuse.org/conference/oSC15
And soon the travel support program for oSC 15 will be opened to handle your request about getting financial support for going to oSC.
https://connect.opensuse.org/travel-support/
If you have any questions, thoughts or ideas, don’t hesitate to ask on -project mailing list
or ping me by reply.
A final note about the why you should do it? Well beside being one of our “heroes” even if nobody need them 🙂
You and your co-maintainers will be able to explain your “job” on the project.
Don’t you want to inspire new comers, lead them directly to the right direction, and share the load.
Meeting you there, will also help our “marketing” force to light up a bit the work done in the shadow.
I really will appreciate your presence, afterwards, it’s you that create our distribution.
The time has come for you to be warmly thank.
I’m looking forward to see you there.
Hi Fellow Geekos,
This post is a summary of my wish to continue to serve on your behalf on the openSUSE board.
My term has been a short one, as I was appointed to serve out the remainder of Vincent Untz’ term.
While I now work for SUSE (and it has been a fabulous experience), that does not change my view or efforts to contribute to openSUSE. Prior to joining SUSE, as a part of the Sales Engineering team, I was elected to the board for a two year term. To avoid having too many SUSE employees, I had to step down. A rule I completely support.
Having been an openSUSE member long before joining SUSE, I think I have a keen awareness of what the community is about and where we can improve together.
My take is we have an awesome group of contributors who want to see the community grow and prosper. With things like Tumbleweed and OBS, among others, we have shown real innovation and technical leadership in the Linux world. We have arguably one the top distros available. It is solid, polished and usable for a wide variety of use cases. We need to keep the openness and solid collaboration which enables everyone to participate and succeed.
My efforts within openSUSE have been mostly focused on the Open Build Server, maintaining several projects, as well as, being part of the Factory review team.
Going forward, I want to concentrate on reaching out beyond our community to build more awareness of what an awesome distro we have, along with a pretty friendly community. I see other, less compelling, distros getting more visibility than perhaps is deserved.
Along the same lines, my take is we as a community can take a more active role in bringing in new members, who might not be technical folks, but can help in the marketing and outreach. I’ve started a local SUSE group through meetup.com which is a different way to find new users and contributors.
One other reason I wish to remain on the board, is we have a solid working relationship and there is a lot of mutual respect and good collaboration.
No matter who is elected to the board, I am very pleased with the caliber of the folks running and know the community will be in good hands moving forward.
Thank you in advance for your vote!

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…)
Hey Christmas time around! AMD give us a new version of fglrx, and Sebastian Siebert just release his script yesterday night.
So I’ve prepared the new version available for openSUSE 11.4, 12.1, 12.2, 12.3, 13.1, 13.2 and Tumbleweed.
Sebastian’s script contain a special patch for supporting kernel up to 3.17 and 3.18 version.
I should also share Sebastian’s surprize about the fact that this version didn’t got a beta/rc cycle….
I hope this release will give better results for all of you who own an apu (especially the recent one), and also fix a number of issue with the hybrid chipset intel cpu/amd gpu embedded.
See below how to report issue on Sebastian blog.
It will be the last build for all openSUSE version below 13.1 (except if patches are needed).
In January 12.3 support will definitively end. But I will let the drivers as is so you can still use them in case of.
Please refer to the wiki page SDB:AMD_fgrlx
The driver is now splitted into different rpm that all need to be installed. Normally the necessary Require field is there and should happen automatically.
My advise is to check if you have them all installed.
for 32 bits
zypper install fglrx_xpic fglrx_core fglrx_graphics fglrx_amdcccle fglrx_opencl
for 64 bits
zypper install fglrx64_xpic fglrx64_core fglrx64_graphics fglrx64_amdcccle fglrx64_opencl
The new release has now its package correctly named, previously they were called SUSEFACTORY, with the new version the package will contain SUSETUMBLEWEED in their name
openSUSE Education Team is happy to announce the availability of Li-f-e built on the latest openSUSE release. Download and spread this love around.
While ago new version 3.19 of UnReal World RPG was released. It was very smooth release in my part. Everything was working as expected. Packages were build to several platforms that were planned. Those platforms were Ubuntu 10.04, 12.04, 14.04 and openSUSE 12.2,12.3,13.1 all there packages build from openSUSE 13.1 base distribution. Nobody found nothing to complain about binary packages before someone launched them on Arch distribution. (more…)
