Welcome to Social Network of Hrušecký Family


Hans de Raad
Just set up the Community​ booth at #LinuxDays Prague! I've got the pleasure of giving a workshop on how to setup your own secure and private groupware and office intranet environment based on the brand new #Univention #Kolab appliance VM image and about the importance of using open source tools to build scalable, privacy respecting websites, an issue which became even more important since the EU high court just ditched Safe Harbour. If you're in town, come have a talk and/or a drink!


I've been playing with +ownCloud +openSUSE +ARM and my old TV :-)

Michal Hrušecký » Introducing OCTV – ownCloud + ARM + old TV


Do you remember my post about how Raspberry Pi revived my old TV? This is partially continuation of that post but also something new. Lets start with recap of what I did almost a year ago. I connected my Raspberry Pi to old CRT TV, installed video player and hacked together few CGI scripts to ...

Ten Habits of a Good Programmer -


Good programmers are born and then made. You need talent and passion, and you need experience. I was lucky to learn from the best, and have lots of opportunity to practice. I'm going to summarize ten of the top habits I've always applied to my work. Cause or correlation? You tell me.

Ten Rules for Good API Design -


Every software developer uses APIs and most of us make them. The design of a "good" API is a black art. You know one when you see one. And yet how many of us could explain why some APIs are complex and hard to learn, while others are clean, simple, and a joy to use. It's a question I'll answer ...

LinuxDays: konference od lidí pro lidi


Konference o Linuxu, open-source a vším, co s tím souvisí. Koná se každoročně v pražských Dejvicíc na půdě FIT ČVUT v Praze.
So I'm thinking about using multiple computers again. But I hit a problem pretty soon. I use everywhere just +Mozilla Firefox and I would like to use my own server for synchronization. Found out that +ownCloud already supports at least some version of the new protocol, but setting it up in #Firefox is #pitta . To use my own server for synchronization I really have to go through about:config? How does it come that after few years situation is worse than last time I tried it? Yep, I read reasons #Mozilla had for developing such a complicated setup, but I know it doesn't make sense in my use case and doubt there is more of those complicated users than simple users like me.

So apart from rant, real question, what do you use? Currently I'm intrigued to try some third party plugins for synchronization, I vaguely remember that some of them supported FTP/WebDAV...

"docker" functionality implemented in 100 lines of bash, very nice hack.  Shows just how powerful btrfs is, along with the 'ip' tool.

Unbelievable. #infosec folks have been warning against this for YEARS. They said: separate infotainment from steering/breaks etc. Do not implement wireless control over this. Have good security measures. This can kill people. It can turn cars into weapons.

And here is a car you can control over the internet - COMPLETELY. From CD player to brakes - thousands of Jeeps can be turned into remote murder weapons, for both the people in them and those around them.

EVERY Jeep Cherokee should be immediately grounded. And let them pay a 500 million fine - just to ensure no car maker tries to save 5 bucks on a 50K car by not separating driving from the fscking entertainment system!!!

Or are we going to wait until a few people are killed? Or for a cyber war where cars are used to take down bridges by driving into them?

Woke up today with completely trashed filesystem on desktop. Spending Birthday re-installing... Thanks Samsung - (A bug in their recent SSD firmware for 840 evo)

My presentation from +openSUSE conference 2015 is live, where I propose using the recently released +SUSE Linux Enterprise sources as an opportunity to redefine the openSUSE Regular Release in an effort to build Stable Linux release that covers the needs of its users as well as Tumbleweed covers the needs of those who want new versions of everything, regularly. Please join the discussion on the mailinglist :)

For those attending +FOSDEM next week, +openSUSE are re-introducing the Old Toad. So if you fancy some fine #opticalexperiments  during the day then pop by their booth.

Although originally planned to be free, there will be a €1 charge per bottle. Proceeds will be split, half going back to the awesome folk of FOSDEM, and the other half will help ensure that openSUSE can continue to bring the amber nectar to events.
