Aqui vai um comando muito interessante que encontrei no Fórum do blog Ubuntued para facilitar na limpeza de kernels antigos. Estre procedimento limpade forma automática os kernels antigos deixando apenas o atual. Não esqueça de ter a certeza de que o kernel atual está funcionando bem em sua máquia. Faça por sua conta e risco, mas comigo funcionou numa boa… Basta copiar o comando abaixo e colar no seu terminal:

dpkg -l ‘linux-*’ | sed ‘/^ii/!d;/'”$(uname -r | sed “s/\(.*\)-\([^0-9]\+\)/\1/”)”‘/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d’ | xargs sudo apt-get -y purge

 

 

 

as you might have heard, we’re providing nightly builds of the parts of ownCloud, which is ownCloud community server as well as the ownCloud client on its supported platforms Linux, Windows and Mac.

The nightly builds of the client for Windows and Mac and the source balls can be downloaded from the nightly directory on our download server. They are named after the last release, followed by a date time stamp, which is simply a concatentation of the year, month and day the nightly was built on. For linux we maintain a so called nightly repository in the openSUSE Buildservice which builds for various distributions. That can be added to the linux package management system and that way every morning, an update is there for you. The ownCloud server is built only in the nightly repository from this daily source.

What are nightlies for?

To test ownCloud is a very difficult task. ownCloud is a complex system consisting of variuos parts (anybody thought ownCloud is just a “LAMP web app”?) which supports a huge variety of environments. That multiplies to a huge variety that needs to be tested. We had issues with that in the past and as a result, providing easy access to ready-to-run testing versions is one important action we are taking to improve quality as that enables more people to participate on tests.

Of course nightly builds are not released software, nor got they extensive testing. Nightly builds must never be used on production installations, please, really don’t do.

But maybe you have a test server or virtual machine somewhere in spare. So it would be great if you could install a nightly version on that, combine it with a nightly built client, and see if everything runs as you would expect it.

Another great purpose of the nightly builds is to use it for bug verification. In client development we often comment on bugs with sentences like this is fixed now, please verify with the current nightly build. That way bug reporter get a very quick way to verify the fix of their issue and developers can be sure that their fix really is sufficient.

How are nightlies built?

We are doing the nightly builds through an instance of Jenkins, a continous integration server. With a little script we wrote Jenkins feeds the OBS every night, so this is completely automatted. But more on that in a subsequent blog.

Today is release day!

We just release ownCloud Client 1.2.5, hurrah! It’s a small bug fix release, but it will make more people happy users! It fixes three ugly crashes we found with the help of encouraged bug hunters. One of them was an race between our thread which runs csync and the Qt SSL stack we’re obviously using. That caused a crash which happened after quite some run time, or also never… Hard to reproduce and debug, but finally Danimo and his mighty friends were able to nail that.

The new client can be found through it’s download page, here is the Changelog.

If you find issues, please help us to improve ownCloud by commenting or reporting the bugs on our bugtracker. Thanks!

I just published a blog post on ARM’s corporate blog with an overview of the recent openSUSE ARM Hackathon. We didn’t quite manage all the tasks that we had hoped for, but we did get the big ones done. For me it was great to meet so many old friends, and some new ones. I’d like to say a few thanks to some of the people involved, they all did so much and this is just some of the things that they did:

This is my 100th blog entry!  

In short, I wasted a few days and a weekend to get my shiny new 12.3 to connect with my company's Cisco LEAP (henceforth referred to as just LEAP) wireless network.

For those who do not have a requirement to connect to wifi via LEAP but are curious anyways, please see this link for LEAP.

To save you the same grief, here is the answer (see screenshot below) on how to configure NetworkManager:

The one on the Left WORKED; the one on the Right did NOT work for me

Disclaimer: Your mileage may vary (YMMV) because I did not test this against another LEAP wifi network outside of my company's implementation.

Το φετινό πανελλαδικό συνέδριο ανοιχτού λογισμικού Fosscomm διοργανώνεται από το Χαροκόπειο Πανεπιστήμιο/Tμήμα Πληροφορικής και Τηλεματικής. Μετά το χτεσινό release party στο hackerspace.gr σήμερα τελείωσε η πρώτη μέρα του συνεδρίου με πολλές ενδιαφέρουσες ομιλίες και workshop από τα μέλη των κοινοτήτων και των ομάδων που παρευρίσκονται στο συνέδριο. Την παράσταση έκλεψαν η πολύ καλή οργάνωση, η πλούσια θεματολογία των παρουσιάσεων και τα ξεχωριστά booth των κοινοτήτων και των ομάδων από τα οποία οι επισκέπτες μπορούσαν να προμηθευτούν ενημερωτικό υλικό και dvd διανομών linux και να ενημερωθούν.

Νωρίς το πρωί μετά το απαραίτητο freddo στο χώρο του συνεδρίου, έκανα εγγραφή στο Registration Desk και ξεκίνησε το στήσιμο του booth της ελληνικής κοινότητας openSUSE.

Η πρώτη μέρα ξεκίνησε με Cloud και μία εκπληκτική παρουσίαση “~okeanos and Synnefo: The public cloud service and the open source software that powers it”  και workshop από τον Β. Κούκη. Ακολούθησαν ομιλίες από τις κοινότητες Ubuntu, GNOME, openSUSE, Fedora και Enlightenment (Ε17) για τα νέα χαρακτηριστικά των διανομών και τις δράσεις των κοινοτήτων. Παράλληλα υπήρχαν ομιλίες για Development Services & GUIs όπως “Getting involved in Mozilla”, Winnie: ένα framebuffer window και workshop για Arduino.

Ακολούθησαν δύο ομιλίες για επερχόμενα παγκόσμια συνέδρια το EuRuKo 2013 και openSUSE Conference 2013 που θα γίνουν σε Αθήνα και Θεσσαλονίκη αντίστοιχα.

Μερικές φωτογραφίες από τις ομιλίες:

Μετά το μεσημεριανό διάλειμμα ακολούθησαν ομιλίες για 3D Printing, Design & Hacks και Arduino. Τέλος η μέρα έκλεισε με ένα ενδιαφέρον panel με θέμα “Πολιτικές Ανοικτών Τεχνολογιών στην Οικονομία και τη Δημόσια Διοίκηση“.

Ένα booth που ξεχώρισε κατά τη γνώμη μου ήταν το booth με το LilPad Arduino και τις δημιουργίες της Smartcraftlab

Με την ευκαιρία το Fosscomm 2013 στην Αθήνα η κοινότητα openSUSE δεν θα έχανε την ευκαιρία να συναντηθεί και να γιορτάσει την κυκλοφορία του openSUSE 12.3 ! Έτσι λοιπόν την Παρασκευή 19 Απριλίου στον χώρο του hackerspace.gr έγινε το Release Party. Μέλη της κοινότητας απ’ όλη την Ελλάδα ήταν εκεί να γιορτάσει τη διανομή, να συζητήσει και να διασκεδάσει.

Hello openSUSE 12.3!  You were released into the big bad world on 13 March 2013 and you are fantastic!


Two weeks back, I installed 12.3 onto a new partition on my primary workstation/laptop in one hour.  By the hour thereafter, and I do need to install quite a handful of additional software, I was working on my day job without skipping a beat.  One of the software that is critical to my job is IBM Notes 9 Social Edition. As covered in my previous blog entry on the beta, IBM Notes 9 has been officially released on 2 March 2013.  Look out for my next blog entry on installing the Generally Available(GA) version of IBM Notes 9 Social Edition on openSUSE 12.3.

Hand on my heart, 12.3 is a very worthy successor to 12.2.  I am very happy with it, and if you know me, that says alot... BUT... there is one little usage/design point with the GUI of NetworkManager that got me confused and I was unable to get onto my office's Cisco LEAP wireless network.  This was resolved eventually (after 3 days and a weekend) and it turns out to be a non-issue... or a usage issue... or... anyway, look out for this in my next entry.

Hello friends!

Here is another wallpaper that I have been working on recently. I want to make this one part of the supplemental wallpaper package for openSUSE 13.1. I hope it strikes the idea of simplicity and keeping the dark colors introduced on openSUSE 12.2.

The idea here is to show simple crystals with some light effects. Looking at it from far away makes it stand out and I think that it enhances your work being unobtrusive and "blingy" at the same time.

Please remember that you can also turn in your submissions for the next release of openSUSE. Everyone is invited to work on an image that they would like be considered for the wallpaper. Something to remember is that if you are making an image proposal for the "DEFAULT" wallpaper, your work will have to be done in SVG format. If the image proposal you are making is intended for the "SUPPLEMENTAL" wallpaper package, you can do it on raster as well as svg. If done in raster, you will have to prove copies of your work in 4 different resolutions, 2560 × 1440, 2560x1600, 2560x2048 and 2048x1536.



Thank you for you work.

Anditosan
