Airsoft

Eight month ago I started playing Airsoft. In the future I will try to post about the games I have participated. In addition I will let you know about, what equipment I have and how it is modified. It is still a draft, but by the time everything will be documented. Additionally, I will keep keep track about gun internals, which are compatible.

For now, this is everything I wrote down so far.

Stupid DNS problems

I misconfigured my DNS, so none of my domains seem to work…

I am sorry for the past crapy looking, disasterious posts on planet.dokuwiki.org. I hope it is fixed now.

PulseAudio Equalizer sink selection

Recent pulseaudio versions provide an equalizer. The tool can be started by running:

$ qpaeq

If the tool fails to start, certain modules have to be loaded first. All information needed can be found here PulseAudio - ArchWiki.

Depending on how many audio devices you have connected, the equalizer might be initialized using the wrong sink, but you can change the sink the equalizer should work with. At first unload - if loaded - the module module-equalizer-sink. $ pactl unload-module module-equalizer-sink

Now get the sink name you want to use. The command (with output example) will give you a brief overview of your sinks:

$ pactl list sinks short
0       alsa_output.pci-0000_01_00.1.hdmi-stereo        module-alsa-card.c      s16le 2ch 48000Hz       RUNNING
1       alsa_output.pci-0000_00_1b.0.analog-stereo      module-alsa-card.c      s16le 2ch 48000Hz       RUNNING
3       rtp     module-null-sink.c      s16be 2ch 44100Hz       IDLE
4       combined        module-combine-sink.c   s16le 2ch 48000Hz       IDLE
5       alsa_output.usb-Logitech_Logitech_G930_Headset-00-Headset.analog-stereo module-alsa-card.c      s16le 2ch 48000Hz       RUNNING

In my case, I wanted the equalizer to work with the “G930 Headset” instead of the “Built-in Audio”. This is achieved by naming the sink_master as module argument on load. For example, considering the above sample output of pactl list sinks short, we will load the module:

$ pactl load-module module-equalizer-sink sink_name="equalizer" sink_master="alsa_output.usb-Logitech_Logitech_G930_Headset-00-Headset.analog-stereo"

Update #1

It is not necessary to unload the module first, this will most likey result in crashing pulseaudio. Just execute the command

$ pactl load-module module-equilizer-sink sink_name=<name> sink_master=<audio device name to use>

take a while and stumble upon

What should this blog post be about? In the past few years I took some snapshots of things making me wonder or milestones in my life I want to share… There are a lot more photos and I just picked a few who coming across my eye by random. So lets start with beer.

BEER

I am a big fan of beer and I like it with a harsh taste and I prefer it without any additional tastes. So it happened to be, that I came across those two strange beer abominations.

Why would anyone mix beer with beer and this mysterious “X”.

I think this is the most disgusting creation of mankind! Since that day I have never bought beer of this brand!

Artistic

Sometimes I try to release my artistic self and do something beautiful or new.

Despite the fact, that I was too lazy to rotate the image before uploading, I really like it.

This is the first real life chameleon I have seen.

Some how this picture makes me feel sad…

Artistical madness

I think the bunny is crazy… I have posted it already a few years back. I got tagged to draw a bunny and this is the result. Funfact: it is an mixture of GIR in his dog suit and a bunny (who wouldn't have guessed that?)

Geek Mode: activate

Those pictures are just a few moments of my life as a geek.

Have you ever tried flashing your BIOS? Yeah, I did once…! Btw, the laptop is now running with coreboot! Funfact: Booting into Linux in 4 seconds, after pressing the power button (to see XDM prompting for login).

The following two pictures are part of my master thesis. I tried to manipulate the firmware of hard drives using a serial console. Funfact: I only bricked one device. This was taken at the Federal Criminal Police Office. Thank you for showing me the capabilities of a PC-3000. (Do want!)

This is the setup I have used during my thesis, to do my experiements.
