A project uses a WEMOS D1 Mini ESP8266 module and Arduino sketch to display local time on an analog quartz clock, automatically adjusting for daylight savings time. The ESP8266 stores clock hand positions in EERAM and retrieves them after power interruptions, allowing the clock to resume accurately.

Why is the sky blue?

163 udit99 2026-02-09 15:52:26 UTC explainers.blog Llama Share 47

The color of the sky is determined by the scattering of photons by small molecules in the atmosphere, with blue photons being scattered more than others due to their resonant frequency with nitrogen and oxygen molecules. The sky appears blue because of this scattering, and its color can change depending on the presence of other particles or gases in the atmosphere.

A Game Boy Advance emulator can implement audio enhancement to reduce aliasing and noise by using its own interpolation algorithm to resample audio channels' sample rates directly to the emulator's audio output sample rate. This approach can produce higher-quality results than accurate emulation and works with any GBA game, though quality can vary by game.

Surely people have thought about this but I couldn’t find anything on a short search. The question: let n be a random integer, say in [N,2N]. It factors as the product of p_i^a_i. So you can think of the proportion of n that is “made of” the prime p_i to be (a_i log p_i / log n). OK, now this gives you a probability distribution. What’s its entropy? You can make this a little simpler by ...
