Strictly speaking, the current messaging code is sufficient to start working on a DOS layer.
That's DOS as in Device Operating System. This is more inclusive than Disk Operating System, for all disks are devices, but the reverse isn't necessarily true. I can assure you, though, that (at least) one implementation of a ForthBox DOS will be a proper DOS.
Confused yet? Don't be. It's just a DOS pretending to be a DOS.
I'll wait until I can resolve my current "codec" loopback bug though. This will eliminate at least one source of bugs from any code experiencing buggy 9P messages.

All this #cyberdeck stuff has me considering pursuing a project I once considered a flight of fantasy.
@requiem @Meandres I agree. Internally to the device, it's definitely more about logic and system design. It's where the FPGA meets the outside world that some electronics knowledge can be handy. And even there we're generally talking about digital electronics (ignoring high speed design for the moment). Any sort of decent "digital 101" course will take you a long way if you're interested in FPGAs. :)
I’ve been pretty heads-down the last year an not keeping up on #hpc as much as usual. It seems I missed the emergence of the “smart NIC”:
I would call this a “dynamic channel processor” but regardless it’s an interesting component and stirs the imagination application-wise.
The article also contains some nice background info on historical use of #fpga.
What happened in texas, why and the process leading to near total infrastructure collapse
One of the most frustrating and horrifying things about what happened in texas over the last week is the fact that, with poor infrastructure durability and preparedness of the texas power grid, what ended up happening was one of the least bad possibilities for how things could have turned out.
According to one report, the texas power grid was "minutes, seconds" away from even more catastrophic failure that would have resulted in months of rolling and sustained blackouts.
Think about that for a minute. Shit was so unprepared and at such a dire level in Texas, that people who controlled the switches had as much time to figure out how to prevent complete infrastructure collapse as you might have to order food at a fast food place.
I don't think it's a bad thing that there are people with enough power to make those decisions. When it comes down to infrastructure, someone has to make decisions, eventually.
More importantly, it's an obscene failure of infrastructure and governance that they had to.
Imagine being the person who has to choose between cutting power to maintain the integrity of the power system, or trying to keep power online and guaranteeing the collapse of the power grid altogether. There's no real choice here.
The grid manager, ERCOT isn't solely responsible for this failure. A large part of the responsibility rests with the state enabling regional power providers within texas to disregard Best Practices in favor of building cheap power generation which didn't meet severe weather durability standards.
As with any infrastructure failure, this isn't a failure at one level, but a failure across almost every level. With a fuckup this bad, there's no single point of failure. It's a cascade of fuckups and negligence that stack up.
Some people might not understand the context of what happened there this week. It's a complicated situation, and that's understandable.
I found this thread in the Austin Subreddit that is a good summary of the infrastructure collapse as it happened.
I'm going to paste a copy of this post in a readable format. This was originally posted early in the storm.
So since everyone is going crazy regarding "rolling blackouts", please read this:
There have been no rolling blackouts in Texas (in the ERCOT-managed regions). Rolling blackouts will ONLY be ordered if, and I quote, "operating reserves cannot be maintained above 1,375 MW". This is the EEA Level 3 alert level. There are 2 previous levels, as well as the current "Conservation Alert" that asks everyone to conserve electricity as we move into the worst of this event.
We are currently in a "Conservation Alert". There have been no disruptions to commercial or residential power. Any outages have been localized due to local power outages like branches on a line or a substation failure.
If things get worse, ERCOT will declare an EEA Level 1, which will direct power operators on this grid to start generating power immediately if reserves are expected to be below 2,300 MW for more than 30 minutes. (We're currently, as of 0:05, at 2,545 MW).
If things get more worse, ERCOT will declare an EEA Level 2, which if reserves are expected to be below 1,750 MW for the next 30 minutes, will cut contracted industrial power.
If things get desperate, ERCOT will declare an EEA Level 3, which will expect reserves to be maintained above 1,375 MW. If not, quote, "If conditions do not improve, continue to deteriorate or operating reserves drop below 1,000 MW and are not expected to recover within 30 minutes, ERCOT will order transmission companies to reduce demand on the system."
Only if it reaches this point will "rotating outages" (read: rolling brownouts) be enforced. The texas grid is solid and only has enforced rotating outages 3 times in its entire history.
With all this said, please do not panic. The grid is resilient and can handle this load if everyone conserves a bit of electricity.
EDIT2: We are currently in EEA1 and should expect further action due to degrading grid conditions.
EDIT3: We are now in EEA2, please conserve as much as possible. Any further actions will result in rotating outages, per ERCOT
EDIT4: CONSERVE AS MUCH POWER AS POSSIBLE, WE ARE ABOUT TO ENTER EEA3. PLEASE SHUT OFF EVERYTHING THAT ISN'T ABSOLUTELY NECESSARY
EDIT5: EEA3 ERCOT has issued an EEA level 3 because electric demand is very high right now, and supplies can’t keep up. Reserves have dropped below 1,000 MW and are not expected to recover within 30 minutes; as a result, ERCOT has ordered transmission companies to reduce demand on the system.
Well this is a spooky-ass read...
