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.

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-main-desktop

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

Resulting in a highly configurable composited desktop:
lxqt-qterm-dropdown

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

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:
X11:lxde:lxqt

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

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

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…)

Emscripten and openSUSE: Hands on.. Hands up!

March 24th, 2014 by

Emscripten logo
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…)

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

I’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

First 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

When 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…)
