Just received merch from the #warp (https://warp.dev) #terminal for taking part in their user interview!

A think I learned a while ago: If you implement a #texteditor, make it possible to scroll past the last line that contains text. If you don't, using it can be quite annoying at times. As a fallback, at least make sure that the viewport scrolls up when you type past the last line, otherwise the text a user types will spill out of the visible viewport once per typed line.

Btw: Don't ever buy an MSI Creator TRX40 motherboard! At least not if you don't want to fully dissamble it just to replace the BIOS battery.

(also it sometimes crashes in a way that reset by holding the power button doesn't work anymore and I need to turn off the power supply)

#golang is the best language ever 🙄 . Ever set a value to 0 via CLI parameter and wondered why it still took the default, then remembered that go encourages using default-Value (0 for integers) as an indicator of absence or "wanting the default value", then set the CLI parameter to 1 and suddenly it is taken into account?

Just happened to me because someone used an int where a pointer to int would have been necessary in go.

Just a reminder: 0 IS NOT THE SAME THING AS ABSENCE OF A VALUE!

I've just signed the open letter calling for the removal of the entire Board of the #fsf and for #rms to be removed from all leadership positions, including the GNU Project.

I'm going to give a #rustlang talk tomorrow: https://www.meetup.com/de-DE/Rust-Community-Stuttgart/events/nnmzcsyccfbgb/

I propose to rename artificial intelligence to artificial Intuition,

because that's exactly what it is most of the time. A machine trained to make decisions based on intuitive "gut feeling". (Note that there are exceptions to that of course, there is machine learning that doesn't work Like that, but most of what ist called AI does)

Today's tip: Don't partition already partitioned data using the same hash function that it has already been partitioned with.

Or: Application specific keys for hash functions are there for a reason, don't use the same for different applications.

Key takeaway: Consider your /etc/shadow to be containing essentially plain text passwords.

-> Don't reuse Linux login passwords for anything else
-> Encrypt your system partition (and be sure to configure a sensible key derivation function when setting it up using cryptsetup, I don't think they use sensible defaults yet. In other words: Tell cryptsetup to use Argon2id and optimise --iter-time and --pbkdf-* to be as slow and memory consuming as acceptable)

OMG, why can't we have nice things. Just found out that passwords in /etc/shadow are hashed using SHA-512 by default (which is the least bad option ...) but only 5000 rounds by default (not that more rounds would make it significantly more resistant against brute force in any case).

Today: Have you ever looked at the semantics of "round" in your programming language. Look at JavaScript and Python for example.

The biggest unsolved problems of applied computer science:
* floating point numbers
* date/time
* text

Just found some interesting code in jemalloc's implementation of a mutex:

if (ncpus == 1) {
goto label_spin_done;
}

Microsoft just open sourced their STL implementation! https://devblogs.microsoft.com/cppblog/open-sourcing-msvcs-stl/
