In my mind, nothing with a circuit board is disposable. Pains me to see it.

why does a glorified heater connected to a battery need any silicon attached to it?
To control the amount of voltage used in making the heat and not immediately burst into flames, for one.
It is interesting to see old tech having clever solutions for stuff like this, these days the answer is 98% of the time is to slap a CPU on it.
It's boring!
Wait til you hear about all the different technologies we use to generate electricity
yep, that’s right - ~~it goes in the square hole~~ we’re boiling water!

I don't get those pieces of crap. There were these fancy electric cigarettes years ago, using those 3.7V rechargeable batteries. Custom designs (saw lightsaber designs), custom liquids, repairable, no e-waste. What is wrong with people to use those crapsticks? And why do those dumbnuts don't get that these things are e-waste not residual waste?

But does it run DOOM?
24 MHz Arm Cortex M0+ processor. The chip also carried 24KB of flash storage and 3KB of static RAM.
... a 10y old phone can barely load Google, and this is about 100x slower.
Wild that you can serve anything with that hardware. Granted, static websites are basically just sending files over the wire.
The 10 year old phone OS probably is slowing all of that. If they flashed phone as a dedicated webserver it would probably be fine
The webpage he hosted was a copy of his own blog post explaining the hack. It just about fit into the 20KB of available flash storage.
We can infer that on every request, the whole static page needs to be spooled out of flash onto RAM (in chunks no larger than 3k), then sent out over Ethernet.
That's an awful lot of work for the chip. I'm not surprised at all that it errors out under heavy load. The request queue probably grows until it collides with the buffer that bucket brigades the web page to the network.
I'm afraid to look up what optimizations were necessary to get that level of performance. It's damned impressive work.

What can I do with my samsung smartphone whose screen is broken?
Hardware isn't the limitation, its willingness to fight locked down hardware and the power management of android. You might be able use ADB to control it, install termux and then with that, SSH server and then a server of some sort.
In my experience, most phones don't seem to boot sans battery, so its just a matter of time until the battery goes poof and your system goes down. Some manage it though - you do get a decent amount of hardware for the power consumption.
