TDR Molotok is IMHO the best thing ever in software and/or hardware when you want the most hyper reactive compressor in existence with reasonably clean sound at extremes.

In my books, when ducking with kick some other channel, it beats ShaperBox3, LFOTool and similar plugins. You get both surgical and musical off-the-bad. The sound just feels right :-)

Molotok is also great alternative to give a shot when having either 1176 or dbx160 would be, or is already used. Worth of trying out.

Storj made me consider a blockchain company. Before that, honestly I did not understand the application. I used it for four months without knowing it is token based and ended my Dropbox subscription. Token is like IP address, totally useless without service that makes it tick. In Storj tokens work as B2B in storage sharing. I just pay with my credit card and enjoy the awesome benefits like pay for use and ultra-cheap S3 object storage, never ever thinking crypto 😀 This is how to do it right.

#systemd sucks for #embedded because it is not a design that downscales effectively. Tried systemd few times for smaller devices but it just a bad solution for anything not at least a mobile phone.

An init system that could both upscale and downscale and based on statically linked tight core would be awesome.

It could even be (partially) compatible with the same unit-file format.

In particular for this project it would make a lot of sense to implement such support because this is a need at scale:

Could even gain sponsorships from embedded companies.

I have now a registered private company for the sake of being a contractor starting from October: Siltakatu Solutions Oy (aka Ltd).

Siltakatu is my home street [1] in #Tampere and I try to find solutions for various issues in software engineering, so by combining these two facts I got a company name 🤷

Sometimes my solutions suck tho but I do not imply anything about quality in my "company brand" ;-)

[1] The #Finnish word silta translates to bridge and katu translates to street.

One wisdom that applies both understanding math and programming in deeper level and navigating through that jungle: be stupid and try not to understand 🤷 Stupid is the new smart.

A power user belongs to a category of users who use computers just for the sake of using them, and that is the overall main goal of using a computer.

I like Low Level Learning Youtube-channel but with this I have I have to totally disagree: https://www.youtube.com/watch?v=3T3ZDquDDVg

The golden rule for writing code and debugging is obviously:

1. Do the most simplest and least scalable trial at first.
2. If that does not scale take a more powerful tool.

I certainly know how to use core files but it is MORE EFFORT.

Since https://github.com/RustScan/RustScan claims to be fast I tried first a trivial SYN scan to my file server:

sudo nmap -sS -p- haaparousku

I got the list of ports in about one second (bit more or less). Then I tried rustscan and got bored enough to finally SIGINT it:

rustscan --addresses haaparousku

Not sure I get the improvement here… Also command-line is not “tactile :-)

Something definitely to improve in Rust command-line apps is not to think arguments as an object tree that you feed into clap crate. That’s just lazy.

Instead a better metaphor for a great command-line interface is something like a game pad that you can “play” easily. That’s why nmap has been relevant for decades.

It would be sometimes useful if #QEMU w/o libvirt could interpret domain XML to some level.

Like for instance if you want to CI kernel, that would be one use case for this.

For the sake of example, here’s the QEMU command-line that I use as starting point for any kernel testing/CI:

qemu-system-x86_64 \
  -M pc \
  -monitor unix:monitor.sock,server,nowait \
  -serial unix:serial.sock,server,wait \
  -drive file=disk.img,if=virtio,format=raw \
  -net nic,model=virtio \
  -net user,hostfwd=tcp::10022-:22 \
  -rtc base=localtime \
  -nographic \
  -chardev socket,id=chrtpm,path=${SWTPM_DIR}/swtpm-sock \
  -tpmdev emulator,id=tpm0,chardev=chrtpm \
  -device ${QEMU_TPM_DEVICE},tpmdev=tpm0 \
  -bios /usr/share/edk2/ovmf/OVMF_CODE.fd \
  "$@"

I had also NVidia interview this week (which went well but I decided to took a position already offered elsewhere) and in that interview I was asked stuff about virtual memory.

Without going details on questions concerning I said that security USED to be a property why we use virtual memory ;-) Now it is the place inhabited by the seasonal flu with its various generations, i.e. Spectre.
