Installing #OpenSUSE #Tumbleweed to my desktop. Seems like a good sweet spot having latest packages and professional QA for a workstation.

Got #Arturia #Minifreak and it is my main #MIDI keyboard now. I was worried that it has the same problem as with #Microfreak, i.e. low audio signal but it is all good. I guess it has better DAC's or perhaps a built-in preamp. The low signal in Microfreak has been a real turnoff for me and have not used it that much, which is a shame.

The synth engine is capable of doing all the basic sounds, except it lacks wavetable oscillator but I'm 100% sure that it will land at some point in firmware update. Why I think it is great synth to use as starting point for any track is the matching #VST plugin. I'm planning to use that instead of #Serum to do placeholder sounds for first versions of new tracks and later phase replace some of them with other synths. Only thing I'm sticking to #Serum is bass because there the wave shape of the oscillator is too crucial to make compromises (as important as the filter).

I'd also like to have 18 dB filter for bass as it is sort of in the sweet spot but as the other engine can act as digital filter, the combination of analog and digital filter can probably be used to find the sweet spot (I some times use two 12 dB filters in series, if a synth lacks 18 dB slope filter).

If I did not have anything else to do I would reimplement this in Rust: https://github.com/microsoft/ms-tpm-20-ref. The code quality is not great in the original and it is not particularly complicated thing to do just time consuming. Looking how bad code quality is, I wonder why e.g. #OPTEE implementation is based on it (if I got this wrong please correct, 99% sure it is).

Writing my own serial port tool in Rust that plays well with #tmux. I like #tio but I'm looking into later expanding mine with built-in #zmodem support. Also, this should give portability across all major operating systems (#Linux, #Windows, #macOS).

probably the most useful effect chain i've made either for #Ableton Live or #BitwigStudio. No longer automating on/off buttons.

considering #radare2 vs #rizin, i’ve settled with rizin because of the standard build system:

meson setup --buildtype=release \
            --prefix=/home/jarkko/.local \
            --default-library=static \
            -Dblob=true \
            -Dstatic_runtime=false \
            build
ninja -Cbuild install

updating is a breeze. no idea what happened to that community, just using what works for me…

having worked with many #infosec #researcher's over the years sometimes (definitely not always) they have a misconception that being able to build and/or detonate a bomb gives you capability to be a great #programmer.

if this was the case, safe thieves should build safes, and police department should be recruited from organized crime groups.

an infosec researcher can also definitely be a great programmer but they are different crafts.

"Toinen yllätys oli se, että poliisi sai avattua vahvasti salattujen palvelimien tiedot auki. Niitä suojannut salasana oli 64-merkkinen, ja sen poliisi onnistui selvittämään."

Tämä jäi itselläkin kytemään, että millä tempulla salasana saatiin selville.

En käytä ruokalähettipalveluja, koska bisnesmalli on moraaliton. Omistajien verojen maksu on taas tämän tosiasian valkopesua.Toisten selkänahasta revitty fyffe on väärin, vaikka siitä maksaisi kuinka paljon veroja.

One thing where I would use #rustlang rewrite: vim/neovim clone. Helix/Amp etc. have the problem that they try to do something new.

Actually the best would be if @neovim would join the club of Firefox, Linux etc. and provide shenanigans for rewriting parts of it in Rust. I promise to contribute in this effort, if that ever happens (no time for working on the shenanigans unfortunately).

printing hex in the #python shell:

>>> val = bin(0x1119e)[2:]
>>> ' '.join(list(map(lambda i: val[i:i + 4], range(0, len(val), 4))))
'1000 1000 1100 1111 0'

I like the #BeagleBone layout in #BeagleV:

Very nice indeed, should get one.

Did you know you could control brightness of the red dot on the i of the "ThinkPad" on the top-side of your thinkpad? I sure didn't:

this turns it off:

echo 0 | sudo tee /sys/class/leds/tpacpi\:\:lid_logo_dot/brightness

and this turns it on:

echo 255 | sudo tee /sys/class/leds/tpacpi\:\:lid_logo_dot/brightness

I don't really know what this information is good for, but hey, isn't it awesome to have a 1px display on the outside of your laptop?
