Save your passwords

If you use a password manager, or another safe place to store your passwords, don’t make any exceptions! December 2015 I bought a new laptop computer. I had the basic setup running and wanted to take it to 32C3, which was around the corner. So I did. Once I was there, I realised I didn’t set up a BIOS password yet. The last time I didn’t have a BIOS password, and left my notebook alone for 5min because I had to pee, someone else generously set one up for me.

Creating Samba shares with Arch Linux

I recently installed a new Arch Linux system to replace an older one. I was in need of providing that Samba share again to access some files from a Windows PC. Setting up Samba on Arch Linux is pretty easy: » pacaur -S samba [...] » cp /etc/samba/smb.conf.default /etc/samba/smb.conf » sudo vim /etc/samba/smb.conf I disabled the printer sharing and other examples, and added the following share to the end of the config file:

There is no valgrind for armv5te

For those who were wondering like me: There is no valgrind for armv5te, and there will probably never be. Has “https://bugs.kde.org/show_bug.cgi?id=248998 ARMv5 and v6 support” been incorporated into release 3.8.1 so that support is now available for ARMv5 and ARMv6. No. ARMv7 is the minimum. ARMv5/v6 is not supported by 3.8.1, and probably will not be supported for a long time. ARMv5 lacks reasonable hardware instruction support for threads.

Errexit in Bash

I have to argue about this option a lot, so I figured writing it down and linking to all the resources will make a good post to point at when this topic comes up again. Many Bash scripts contain the option -e (or errexit) for “error checking”, to make the script exit when something goes wrong. I put this in quotes, because it actually just checks if a command exits with a non-zero return value.

Orbital Reflector

Trevor Paglen is an artist that has actually earned this title, in my opinion. Many of his art projects are concerned with this abstract “mass surveillance”, and how one could make it observable. Examples are photographs of espionage satellites or of giant undersea internet cable taps. I stumbled upon him by accident on my very first visit to the Chaos Communication Congress, the 30C3. Owing to favourable circumstances, I sat in his talk Seeing The Secret State: Six Landscapes, where he showed an overview of his work on surveillance.

SHA2017

I had the pleasure to attend this year’s hackercamp in the Netherlands, the SHA2017 (“Still Hacking Anyways”). After missing out on the Chaos Communication Camp 2015, I immediately grabbed a ticket as soon as they were available. As for the congress each year, I grouped up with the local hackspace Mainframe and became part of the village. We arrived at day -1, so we caught the last bits of the buildup, while setting up our village ourselves.

Nordlicht 2017

Last weekend was my first time to attend the Nordlicht demoparty, which was also my first visit to a demoparty at all (“demo” as in demoscene). I had sporadic contact to demos before—sometimes youtube suggested me some recordings of demos, sometimes Rene blogged some on nerdcore, and I even knew some people who attended this very party before. But I never had contact to “the scene” itself before, and was intrigued what it may looked like on one of those events.
