I know, but part of the logic from below the line I linked could have been deterministic, it could benefit from a single "load skill" tool that just loads the files client side!

The bad part is that it cannot create a world wide mesh, as has a low max hop limit (7), and the nodes need lines of sight. So more than 200 km in a mostly flat city is almost imposible.

I wish we had an HF ISM band that could be used for this purposes without needing a license, combined with LoRa radios would yield great results

Hmm, it's a clever hack, but they would use an oscilloscope with an "External trigger" input, like most of the older Rigols. That would let you use the full sample rate without needing to trigger from CH2

Indeed, if you search for "ceramic antennas" you'll see that they are already being used and smaller than equivalent PCB antennas. They rely on a dielectric material with high e_r, which implies that speed of light is slower there. Lots of portable devices use them nowadays!

No-name phones end up using chipsets/radios from varios manufacturers: unisoc, broadcom, mediatek, rockchip, ...

They can just grab a reference schematic and pcb and tune it a bit and get it manufactured. They all use mostly the same interfaces and protocols, like mipi dsi for lcds, so they can have many almost drop-in alternatives to choose depending on availability.

For printheads, it's likely that there are no common standards, each manufacturer has it's own head-cartridge interface, so it's probably more expensive to remain open to changes, reducing the potential profits

Argentinian here. Article has some flaws that could cause a different perception of the situation:

- The income tax isn't really "eliminated", that's not right, it just has a higher starting point and is now indexed to the monthly wage. Otherwise it required yearly updates that were quite messy. It starts to apply to gross salaries above 15x the minimum monthly wage (the starting point used to be WAY lower).

- 1.7 million pesos isn't really 5k USD, as no one has access to that exchange rate. It's more like 1800~2000 USD monthly.

Overall I think it's a good measure, but it still doesn't tackle the elephant(s) in the room: Having >40% poverty, having an unrealistic exchange rate, low minimum wage, informal economy and workers, problems renting/buying real-state, unsatisfactory education results...

GraalVM for JDK 21 3 years ago

We tried to use it to improve AWS lambda startup times but desisted as it was a pain to use it with an existing app. It required too many tweaks as there are waay too many things that rely on reflection :(

Things that broke include: JSON (de)serialization using Jackson, validations using hibernate, validator, AWS SDK, and even simpler libs like picocli...

It could be quite useful for a set of simpler apps though

There's one weird thing that I've noticed with Daft Punk's The Brainwasher, my brain has two different interpretations for the main loop offset:

If starting here, I hear a loop that starts with fast notes and then has a silence. (warning: loud) https://youtu.be/RdVEQbWjaTE?t=91

If starting a few seconds earlier, the previous melody seems to fuse with the part that starts at 1:30, and it sounds different, like a bit slower. (warning: loud) https://youtu.be/RdVEQbWjaTE?t=80

Not sure if that makes sense, hopefully some one else also hears both versions! I'm assuming it may have to do with interpreting the last note of the loop as part of the next one, but it could be something else too. It really is a brainwash :P
