@mos_8502 Hey, let's make a social network without central authority, and let communities self moderate!

No, not like that!

Whenever you wish to make a goofy prompt to a LLM, think of all the resources wasted on "blinker gluid", "edible glue" and "ligma symptoms"... #AI #LLM #ligma

These prompts are an important proof that LLMs can't produce sensible answers all the time, and can't be trusted for anything other than producing word salads. But please, don't overuse them. (oooh! I have to prompt "recipe for word salad" and heat the planet some more...)

Manjaro is still shipping the 5.6.1-2 version of the xz package. #xz #liblzma #cve20243094 #manjaro @manjarolinux

EDIT: probably a false alarm on my side, but check your version and available update - 5.6.1-2 should be "good"

Prusa Slicer says TPU isn't compactible with MMU2S multi material mode. Which is reasonable, since I hot a filament jam as soon as I tried to load it. Still, I might try to do a flexible/rigid composit later on... (PLA/TPU or something with compatible extruder temps). #prusa #mmu2s #tpu

So, next in line is a flexible filament I had on hand: colorFabb varioShore TPU. I'm using the Prusa Slicer preset, with temperature set to 190C. #3dprinting #TPU #colorFabb #varioShore #prusa #CompliantMechanisms @3dprinting

Of course, I stared fidgeting with the switch as soon as the print was done... The switching was very pleasant (not too much force required - I need to find a tool to measure it). It was so easy to switch, I just started flipping it quickly and counting. It's possible I overheated it - the first hinge to fail was the one connecting the base and the lever of the switch, not the ones on the "free bar". The free bar ones failed fairly quickly after some more fidgeting. Need to try it in PLA, ABS...

Here's the source page... Printed in PETG (personally extruded by Josef Prusa himself, lol), 0.4mm hardened steel nozzle, textured print sheet, 0.2mm layer height, 15% infill. Default settings for Josef's PETG in PrusaSlicer 2.7.2.

@jonny We can play with drink selection - Red Bull, sugar-free Red Bull, a local energy drink ("Guarana"), maybe also with a sugar-free variety, Coca Cola, Coca Cola Zero, and local soda without caffeine ("Kokta" + sugar-free "Kokta"). I was thinking in lieu of factorial design and repeated measures ANOVA. We need to work out the details: do we test each volunteer for each drink? Are we bound to just one test a day, per volunteer? Do we measure baseline reaction times only once per volunteer?

@jonny Hey Jonny! Would you be willing to share some advice on a very basic experimental design, for a student project? We wish to explore if energy/high-sugar/carbonated drinks impact/reduce student reaction times (measured with Backyard Brains Muscle Spiker + Reaction Timer). The project is aimed to be an exercise in experimental design (neurophysiology is just the research context). The general idea is to measure the reaction times of volunteers before and after consuming the drink. 1/2
