I really would like to have a simple re-implementation of ye olde TNC-2s that had a small eprom and a kiss mode TNC with a fricking BBS on ax-25 that worked like a charm. They existed I believe around 1988-1990ish.
I mean, yes, this cable works with direwolf, but then I need to have a full linux system running, which I could do without for the purpose of an emergency comms system.
I have one of these in the garage. I think they're 6502-based with the OS on EPROM, or at least that's what I vaguely recall from last time I had mine opened-up about 20 years ago. I can dump the ROM if it'd help.
They run on the rate of change of chip production. To make up for the loss of China chip production in the US/Europe would have to increase the rate of change ie grow exponentially.
Going forward how bad of a move this is for one of Europe's leading tech companies will be apparent IMO. It's all about the moat. The sanctions started to fill in the moat when they catalysed a massive investment on lithography in China, but did wonders to preserve the moat of Nvidia, Intel, ARM, etc by setting their Chinese counterparts back a decade.
EU chip production is negligible, the change rate is positive but again negligible (single 16nm fab). US has some spending but rely heavily on Intel. That says a lot. So, it's Taiwan and Korea. Though TSMC and Samsung are scaling up capacity, they won't do it to the scale as AI-bros want it. It's too big of a risk to have over-capacity in a downturn. This happened in the past several times and the industry learned to always stay couple of steps behind the hype. Similar to oil and gas industry.
I agree that their is no lack of demand for chips. But the cost of building a brand new fan, or even upgrading one is massive.
Were talking a small market of countries or super massive corporations that could possibly afford to build a fab.
The revenue is that eventually hardware needs to be replaced, and existing fans have to either upgrade or scale horizontally if they want to keep up with market and demands.
I always wondered if you can orbit inside the event horizon of a large black hole and wait until its hawking radiation shrinks the event horizon so that you find yourself outside. You would have to wait a long time I guess.
Won't this "long time" be only for the outside observer? Won't the person orbitting experience much less time and actually could get to watch the black hole evaporate?
Maybe off-topic, but are there good solutions for esp32/other microcontrollers controlling zigbee devices ?
I found a bunch of libraries (e.g., https://github.com/espressif/esp-zigbee-sdk), but nothing that seems easily usable as a zigbee controller/hub to flip switches in the house, out of the box.
OTOH, running home assistant on a pi is monstrous: overly general and bloated for my use case, need a beefy Pi to get decent performance and not need >1 minute to reboot after a power outage.
I mean, I know it’s lame to say ai is the solution to everything but here it seems to make sense to me.
