   > 6.6 megaflops vs the original 6.6 gigaflops. Hmm... I think 9800X should be able to do at least 32 FLOPS per cycle per core. So 1.3 TFLOPS is the ceiling for the CPU. 1/100000 leaves you... 12 MFLOPS. Then there's the iGPU fo

   We could call it Bender.

   Do we really still have the society wide institutional knowledge to do things how they were done 50 years ago? I wouldn't be so sure.

   It could also happen as natural decay over centuries. There's no guarantee we'll get more advanced over time.

   We're toast should we ever lose ability to make CPUs. Perhaps there should be more research how to make small runs of chips cheaply and with simple inputs. That'd also be useful if we manage to colonize other planets.

   Venus probably doesn't have enough hydrogen to be of any use.

   I think RP2040 does not support UART booting.

   That requires having a flash chip in the first place. By booting via UART you don't need any flash at all.

    It's not just the user interface. UI is just the tip of the iceberg. It's also firmware for all those controllers all over the car as well.

    One could also send a binary stub that sets up fast CPU clock speed and decompresses the rest of the firmware at the RP2350 side. Should be even faster. Just like old C64 decrunchers and Amiga PowerPacker. Or Fabrice Bellard's LZEXE. (

    I think this Win32 app could be done in C under 20 kB.

    Wasn’t POKEY out of tune due to limited frequency register? Making it hard to produce music that sounds good.

    Decompression is your friend. Usually CSV compresses really well. Multiple cores decompressing LZ4 compressed data can achieve crazy bandwidth. More than 5 GB/s per core.

    That probably just means it's a memory bandwidth bound problem. It's going to be a different story for tasks that require more computation.

    Such an odd choice not to have a timer interrupt on Apple II and then having to do this kind of trickery on a MouseCard. I guess this saved a few bucks...

    Just like Amiga OCS/ECS. 4-bits for each red, green and blue.

    Oh damn. I've dropped SSE ages ago and no one complained. I guess the customer base didn't use those chips...

    > Which still means you have to write your code at least thrice, which is two times more than with a variable length SIMD ISA. 256 and 512 bits are the only reasonable widths. 256 bit AVX2 is what, 13 or 14 years old now.

    Sometimes relatively trivial actions can save millions. Say, finding a "simple" bug in the firmware causing a lot of expensive industrial PCBs appear completely dead. Millions of dollars of savings in service personnel travel and

    The air purity requirements for fuel cells are rather demanding. Impurities will destroy them. ICE air filter would destroy them in no time.
25. 325.▲
    by vardump 1y ago

    Don't fuel cells require air without any contaminants, thus air filters? So you still need filters, this not for the exhaust, but for the intake.

    Unless you use only cartridges, BASIC ROM is required to load anything at all from disk or tape. Once your program loads you can turn the BASIC ROM off to see the RAM underneath. Commodore MAX Machine was basically a stripped down C64. It h

    I think you're fully protected from Terminator and Bender. Neither will dare to attack your residence.
