Wish they would get around to updating the PFS suites though. They appear "stuck" at a 1024 bit keysize....

Registering for #LGM  2014
I'll be attending next weeks LGM in #Leipzig  on behalf of the #Rapicorn  project. Drop me a line if you like to meet up, I always fancy a coffee. It must be some 7 years that I didn't manage to attend, so I'm really looking forward to the event this time ;-)

RR - #debugging  through process execution replay

This looks like an incredibly interesting debugging tool, initiated by Mozilla Research:

You record your process execution under #linux  and later replay the same execution with the exact same memory layout, syscall results, etc, all with #gdb  attached. Effectively allowing to go back in time of the process execution as many times as needed to hunt down a race condition.

A presentation is linked to at the end of the page, that explains how it's all done by rr, it includes some nifty tricks around performance counters and syscall interception...

Definitely gets my innovation star of the week ;-)

It's a fantastic idea and I'm very impressed that they managed to make it work.  I dug through the bug tracker a little and found all kinds of interesting nuggets of information that made me very happy that I wasn't the one trying to figure out what was going on :-)

Great example on why it's inferior to look for just your own good...
"A group of 50 people was attending a seminar. Suddenly the speaker stopped and decided to do a group activity. He started giving each one a balloon. Each one was asked to write his/her name on it using a marker pen. Then all the balloons were collected and put in another room. Now these delegates were let in that room and asked to find the balloon which had their name written, within 5 minutes. Everyone was frantically searching for their name, colliding with each other, pushing around others and there was utter chaos. At the end of 5 minutes no one could find their own balloon. Now each one was asked to randomly collect a balloon and give it to the person whose name was written on it. Within minutes everyone had their own balloon. The speaker began— exactly this is happening in our lives. Everyone is frantically looking for happiness all around, not knowing where it is. Our happiness lies in the happiness of other people. Give them their happiness; you will get your own happiness. And this is the purpose of human life." (Source imgur)

Potentially Vulnerable Industrial Plants

Eeek, Heise reports (in German) on an "Industrial Risk Assesment Map (IRAM)" created by the DFN, which visualizes vulnerable industrial installations. A scary map:

Sun Over Berlin
We've recently moved to #Berlin , which turned out to be much more labor intensive than originally hoped for. I love the city and weather here has been really nice lately, I'm looking forward to find more time exploring it.

Also, if the wiki isn't too outdated, Berlin also seems to offer a variety of hackerspaces worthy to investigate: 

I'd appreciate people dropping me a line if you know about interesting locations around here or fancy a meetup over coffee/beer ;-)
