I'm not talking about an audio-DAC chip attached to a MCU. I'm talking about the most basic of analog designs that would transmit data over 4-20mA (just controlling an OpAmp + Transistor passing some currents). By the time you add

RP2350 doesn't have a DAC or Comparator. ESP32-S31 has... none. No DAC, no Comparator, no ADC. "Literally and completely nonexistant" is about as bad as you can get. Like the reason to reach for a PIC or AVR these days is bec

ESP32 and RP2350 have pretty crap or nearly non-existent analog. I don't think they even come with a comparator, let alone rarer analog parts like a DAC. If you need a DAC, Comparator, ADC, and a couple of logic gates, its hard to beat

Richard the Lionheart spent 10 years away from home and at most 6 months in Briton. Do you know why he was fighting in wars in far away lands? It certainly wasn't about land or power (at least, not for Richard) It was a Crusade. The 3r

The King of England isn't in charge of the UK though. The power largely rests in Andy Burnham. The job of the monarchy today is largely traditional. They pass and bless today's (better) government systems. > The monarchies and

Good question. Followup question: do you know the story of how the Frankish Kingdom of Charlemagne the Great got split up into Lombards, France and HRE (basically modern Germany) ?? Kings juggled the conflicting tasks of choosing an inherit

That's mostly a feature of monarchies. Even in European settings, monarchs claimed divine right to rule. That's why ex: El Cid (a great knight/military commander in Spain) was a threat to King Alfonso. (Doubly so because El C

You know that GPUs are more flexible than just linear algebra, right? GPUs are simply faster at fundamental algorithms like sorting (which has huge parallelism), and hashing. This is because both sorting and hashing benefit from endless gro

Parent post was talking about an 8GB dataset. 8GB isn't even CPU RAM these days. That's GPU super-mega-awesome ram. Ordinary Server CPUs are regularly pushing 2TB capacities. GPUs are in the 8GB to 32GB typically, at least for sma

With a 4B parameter model that probably ran through 8GBs of RAM multiple times to run. At a certain point we should seriously talk about CUDA accelerating Postgres instead.

Leaded Gasoline. If we don't like a technology we can easily get rid of it in practice. And by that, I mean that Leaded Gasoline is infeasible to be profitable anymore. So no gas station serves it any more. And please, it will be easie

Oh, and finally. AoE2 is played on "Random Map". This means that scouting has a degree of importance. In general, you should scout on chickens maps, and you should mix up scouting vs luring on deer maps. Chickens cannot be lured,

Sometimes SC2 was anti APM. Other times, SC2 adds chronoboost / MULEs for no other reason than to eat up APM and provide an outlet for physical clicking and increase APM. As it ends up, SC2 is randomly anti-APM and pro-APM, depending o

Yeah it's meaningless to fight. Except not really. If the powers that be are corrupt we can simply keep calling it Lake Ontario across the board, and use the difference to find who is or isn't on my side on that issue. The only pe

Focus??? These bands have names. The 2.4 to 2.5 GHz band (100MHz bandwidth) is named the 2.4 GHz band. The 5.4 to 5.7 GHz band is called the 5GHz band. The 5.9 to 7GHz band is called the 6GHz band. Anyone discussing the bands should know th

Higher frequencies support higher bandwidths though. I don't think the 2.4GHz band even has 160MHz free, for example. Literally impossible to support because 2.4GHz to 2.5GHz is all you get (100MHz or so). 5GHz isn't much larger t

And furthermore, the unlicensed spectrum problem is complex. "Anyone transmitting" includes Bluetooth devices, and Zigbee, and many other protocols that will never even try to follow the 802.11 spec.
