This example attempts to keep temperature to a fixed point by turning on a fan when a thermistor gets too hot.
You can test it easily if you are not in a place that is too hot by holding the thermistor with your finger to turn on the fan.

List of GPT models 2025-08-08
For inferencing just a single prompt, things appear to be very obviously memory bound, i.e. bound by the transfer speeds of VRAM to GPU cache for loading model parameters into GPU so they can be used, supposing that the model fits in VRAM, which is the case for many popular models.
It is however possible to make fuller utilization of the GPU's compute power by running multiple independent queries in parallel, this way you load the subset of model weights that you need, and then use those to do part of the inference for multiple input prompts. With this it should be possible to reach full utilization.

LLM inference batching 2025-08-08
This can be used to overcome the fact that most single prompt inference will be heavily memory bound, see also: Section "Theoretical peak performance of GPT inference". Batching helps increase the GPU compute utilization and balance it out with the memory.

Microcontroller plus circuit emulation 2025-08-08
There were still no amazing open source implementations as of 2025.
This section is about emulation setups that simulate both the microcontroller as well as the electronics it controls.

Historical WHOIS database 2025-08-08
A "DNS database" is a database that stores DNS records, notably A-records, which IP a domains is hosted at.
For currently live domains, domain to IP can of course be easily determined on the fly by just resolving the domain like the browser does, e.g.
cirosantilli.comWhat is hard however is:
As of 2023, working with DNS data is just going through a mish-mash of closed datasets/expensive APIs.
We really need some open data in that area.
