What's the expected lifetime of the average hard-drive in a datacenter? And does Amazon allow next day delivery to the Moon?


Wasn't there an GA FPGA design to distinguish two tones that was so weird and specific not only did it use capacitance for part on its work but literally couldn't work on another chip of the same model?


Yes, indeed, although the exact reference escapes me for the moment.

What I found absolutely amazing when reading about this, is that this is exactly how I always imagined things in nature evolving.

Biology is mostly just messy physics where everything happens at the same time across many levels of time and space, and a complex system that has evolved naturally appears to always contain these super weird specific cross-functional hacks that somehow end up working super well towards some goal

It's mentioned in a sister comment: https://www.damninteresting.com/on-the-origin-of-circuits/


As I recall it didn’t even work from day to day due to variance in the power supply triggered by variance in the power grid.

They had to redo the experiment on simulated chips.


Yes. The work of Adrian Thompson at the University of Sussex.

I think it was that or a similar test where it would not even run on another part, just the single part it was evolved on.



Sphinx C-- maybe?


Is that microsoft C--?



Had a look, its syntax is already too rich: I saw "while" "switch" etc.

I guess, we are looking for even simpler thas sphinx c--.

I start to wonder, if I could not express such simple C syntax using a powerful assembler macro preprocessor (like the one of fasm2). Until there is a "expression" processor, it should kind of be easier.


You didn't have to replace the house's wiring at least (Happened to an aunt of mine: Gave her a computer, it worked perfectly outside of her home. The electrician was a tad horrified. She still scoffed when I suggested the computer wasn't the problem first.)


I plugged my old Atari into an outlet in the old basement in a different building. The HDD-cable started burning.

Electric company plugged in some device to measure power over time. Turns out the power was slightly below normal but within tollerances. The OEM power supply that was powering my Atari wasn't up to standards. If I remember right, badly designed PSU's can feed too high current if the voltage is too low. Or something like that, was a very long time ago...


Many switch mode power supplies will increase the current draw if the voltage drops, that's why many of them will work on both 120 and 248V, while old school power supplies need a manual switch. I had a brownout once and thought my washing machine was broken because that was the only thing that stopped working (Until evening when I switched on the lights. That was back in the days of incandescents, oddly though led lights still dim with lower power, I don't know how they do voltage conversion).

We have so many cheap power supplies in our houses that it would not surprise me if at least some become unsafe if the source voltage drops too low. Being unsafe with only a slight drop is weird though.


Yeah, lucky it didn't get that far, "Sorry bro, I gotta try just replacing your house."


If between rice and water, you replace the rice with chicken broth, I'm pretty sure you don't get to cook much rice...


I can do something not unlike that with the second-hand displaylink adapter I currently have gathering dust... I would just need to install a desktop environment on termux for it to be complete (not sure if I could get 3D acceleration with this). The only real problem there is the adapter I have cannot charge the phone while connected.


I use Lutris for that, a bit clunky (especially updating games) but it does work.


Port a mips emulator for it so you can run Linux on it?
