Days since I installed Debian on a new computer and completed a complex manual partitioning scheme involving stacked md, dmcrypt, and lvm while forgetting to create an EFI system partition, and so having to do the whole thing over from scratch:

0.

Argh. The installer should warn you about this earlier in the process. I always forget because I only do this every 3 or 4 years.

TIL YIG filters (Yttrium Iron Garnet), which is used in microwave RF filters to make a pass-band that sits north of 3GHz.

This does _nothing_ to dispel the notion that RF engineering is just modern alchemical bullshit. Look at this simplified representation of a YIG filter on wikipedia. Oh yeah, you pass two microstrips at an angle near a mysterious Sphere Of Filtering, and its ravenous maw consumes the 0-3GHz frequencies to feed its demonic ambitions. But sure yeah, enjoy your filtered signal.

Genuine question here for Linux users and musicians, composers, guitar players etc. I am being told by several mouthy people online that "nobody uses linux" & "nobody would use linux for music making"

How many of you use or have used Linux as a vehicle for recording music?

Please retoot/repost to help get a handle on this, cheers!

When it comes to your #distro, are you?

Yeah, I think this is the correct interpretation of the symptoms I'm seeing. The surprise was where/when the side-effects (of removing that element from the $(1..NF) array) happened. And because it happens before the $ can obtain the value, the $ returns the empty value.

I can justify it, it just surprised me ☺

After 17 years, I finally switched from #Ubuntu to #Debian.

The reason has only one syllable: #Snap. After years of slow improvement, I had major trouble with it again in April. Snap is poorly designed software, existing only for strategical purposes of Canonical.

By the way: Most people who can install Ubuntu, can also install Debian IMO. It really is mostly the same.

Random electronics history: a common logic primitive in electronics is the Schmitt trigger, a comparator with hysteresis: rather than switch between logic low/high at the same threshold in both directions, the threshold for low-to-high transition is higher than that of the high-to-low transition. This is nice for cleaning up noisy inputs, among other things.

Why's it called a Schmitt trigger though?

Predictably, it was invented by grad student Otto Schmitt in 1934, while he was studying the electrical properties of squid nerves. He published it in his PhD dissertation as a "thermionic trigger", which let's be honest is a much cooler name and sounds like a component of a doomsday device.

He also made significant contributions to the invention of the differential amplifier, again as part of studying neurobiology.

It's a nice sort of immortality, to give your name to a fundamental and ubiquitous piece of circuitry. That you invented while pursuing a completely unrelated field.

(also I'm going to assume that "invented by" is likely an oversimplification, and that many of these ideas were in the zeitgeist of the time, but history likes simple stories where ideas spring fully formed in the mind of a single genius)

On FreeBSD, which interactive shell do you primarily use for your non-root user?

If "other", perhaps leave a comment about which shell it is.

#FreeBSD #shell #sh #bash #ksh #zsh #fishshell
