GPS time, leap seconds, and a clock that's always right has been released on media.ccc.de and YouTube #emf2024 #talk #StageB https://media.ccc.de/v/emf2024-337-gps-time-leap-seconds-and-a-clock-thats-always-right https://www.youtube.com/watch?v=u2wyY0CTiXo

Interestingly, BMCs in the Supermicro server are based on ASPEED SoCs.

These SoCs include a USB Device Controller capable of emulating a USB hub via the Linux kernel USB Gadget subsystem. This is the only such controller known to me.

apparently you can get from Plymouth to Wayland in less than 15 hours

#Wayland #inputmethod team GO!

I assembled a team to continue work I started for #mobilelinux with #phosh , #squeekboard and #librem5 .

We're going to finish the mobile side of screen-based input, and also try to properly bring traditional input methods (like for Chinese) to Wayland.

Thanks @nlnet for providing the motivation.

Just two days left until the first hearing Newag's lawsuit against us (Dragon Sector members) and SPS. It will take place on 28.08.2024 at 10:00. In case you've missed it, we're being accused of infringing upon Newag's intellectual property and unfair competition. This is, of course, bullshit and a great example of a SLAPP case.

@fasterthanlime @Kahanis @uint8_t @mntmn @timonsku @dos I really dislike it that when I ask a question I can't easily answer--which is a *really big share* of questions I ask a search engine--an LLM is straight up lying to me, in a way I can only recognize *because I'm already a domain expert* who was in the field since high school

what if I wasn't? what sort of bullshit would I "learn" then?

There will be #phosh stickers and t-shirts at #FrOSCon. Join us in the mobile dev room (C117).

I've tagged version 0.0.2 of #libcmatrix - a #matrix client library.

This release focuses on making Matrix support in #chatty more robust, simplifying some APIs and improving the documentation (which is now automatically generated at https://agx.github.io/libcmatrix/)

See https://source.puri.sm/Librem5/libcmatrix/-/releases/v0.0.2 for the list of changes and contributors.

I got an unexpected mention in the release of Raspberry Pi's RP2350 chip.

Nice to get a mention, but I hope the security is broken, so the amount of unrepairable devices and e-waste can be reduced.

PartLint is now released on https://git.sr.ht/~martijnbraam/partlint

Also added a small utility for calculating LCSC basic part resistors :)

Dear distro maintainers and "i build my own stuff" people: In case you want to check out 0.41.0 upfront: we've tagged the first releases candidates of #phosh and related components today. Release is planned 2024-08-15 (https://gitlab.gnome.org/World/Phosh/phosh/-/wikis/Releases)

Something I've found interesting about ADHD is one of the most ignorant comments "adderall is literally just meth lite" isn't really wrong, and most of the response to it, imo, do more harm than good. I think a lot of the issue is there is a huge stigma surrounding meth, and people taking adderall don't want to be associated with that stigma, so they have a extremely negative response to this statement (it is also typically made in bad faith, so there's that too).

But I think people would benefit from understanding a bit about ADHD, rather than fearmongering. Meth is actually an FDA approved treatment for ADHD, for exactly the same reason that all the other stimulant medications are. Adderall is a mix of amphetamine and dextro-amphetamine. Meth is methamphetamine, a much more potent amphetamine. It's not a coincidence or a side effect that highly addictive drugs treat ADHD, they treat ADHD for the same reason they're highly addictive drugs.

I'm going to oversimplify a bit for laypeople, but essentially a lot of the ADHD symptoms stem from their brains having a natural deficit of dopamine and norephedrine. Dopamine is involved in regulating the reward system (motivation & feeling of accomplishment from achieving goals). Whereas norephedrine regulates the fight-or-flight system (which also affects motivation and energy levels). The deficit of both of these neurotransmitters is largely responsible for people with ADHD having extremely low motivation and executive function. The deficit of norephedrine, I suspect, is why people with ADHD are able to treat some of their symptoms by deliberately putting themselves into stressful situation, thereby naturally boosting norephedrine.

Anyway, when it comes to stimulants, being "high" is essentially just your brain experiencing above baseline levels of dopamine and norephedrine. Stimulants boost dopamine and norephedrine, which is what is why they get neurotypicals high. But when given to someone with a deficit of those neurotransmitters, such as someone with ADHD, it simply just boosts them closer to normal levels. Because the symptoms of too high and too low levels of those neurotransmitters can be similar, it led to the myth that "adderall has the opposite effect on people with ADHD".

What's actually happening is the restlessness/disorganized thoughts/lack of motivation in people with ADHD comes from having a deficit of dopamine and norephedrine. So, as you increase the dose of stimulant medication, their neurotransmitter levels get closer and closer to a regular baseline level, leading to a reduction in symptoms. But if you give someone with ADHD a too high dose of stimulants, it's possible to increase their dopamine or norephedrine levels above baseline, leading to them becoming "high", and their ADHD symptoms returning.

This is likely why many studies show that Adderall doesn't actually boost the productivity of neurotypicals. What's likely happening is the excess levels of norephedrine and dopamine negatively impacts their performance, but since dopamine interferes with the brains reward system and increases feelings of gratification, they simply perceive that they are accomplishing more than they actually are.

The reason why people with ADHD don't find their medication to be addictive is because they're not taking recreational doses of it. They're only taking the appropriate dose to boost their neurotransmitter levels up towards the normal levels, which allows their brain to function similar to a neurotypical's. There's essentially no non-recreational dose of stimulants for neurotypicals (any amount will get them at least a little bit high), but people with a deficit of those neurotransmitters can take low-medium doses of stimulants without getting high, hence the difference in effect and outcomes.
