It blows my mind that for ÂŁ7 I can have a tiny computer with 5Ghz WiFi and program it to make hardware gadgets.

This time I've made a remote controller for PC fans. It sets and measures RPM, and integrates with #HomeAssistant

Let's Encrypt bans certificate usage in any US sanctioned territory, https://news.ycombinator.com/item?id=48453275.

Here we are. Let’s Encrypt is not trustable anymore. Any alternatives?

Feeling sad.

"the body keeps the score" okay so i thought we were playing for fun and now i'm upset

They say every #billionaire is a policy failure.

A #trillionaire (a word so obscene my spellchecker marks it as illegitimate) is a civilisation already crumbling, a distortion of human flourishing so severe that it signals (and accelerates) a system destroying the conditions of its own possibility.

Whatever dazzling brilliance apparently shines forth from #plutocracy is merely the glow from the combustion of the house we all share.

I employ a two-pronged defence against phishing:

First, I am so behind on reading my email that, by the time a phishing message actually gets read, the original scammers have probably had their site taken down, or maybe died of old age.

Second, I don’t know any of my passwords and, if your domain doesn’t match, my password manager won’t fill them, and I’m much too lazy to fill them manually, so will probably just close the window. If it looks important, I’ll flag the email and come back to it eventually. Maybe.

NEW: Trump Administration Killed Criminal Investigation of GOP Senator’s Coal Companies

EPA and Justice Department officials were looking into potential criminal violations by the vast coal empire owned by Sen. Jim Justice. Then the Office of the Deputy Attorney General told them “pencils down.”

For sound insulation everyone recommends mass loaded vinyl (MLV), but that barely made any difference in my case. MDF/wood is thick and heavy enough on its own.

Foam easily eats high-pitched sound, but low-freqency harmonics almost drove me mad. 5700RPM HDD turned out to have 95Hz harmonic that spread through everything, including foam, felt, rubber feet and my floorboards!

High freq needed closed foam, and the low freq needed layers of butyl rubber mats (for car sound deadening).

For the base of the acoustic enclosure, I've used IKEA ALEX. Tight fit. Shelf used for a 12cm duct at the top.
I've used pair of Noctua NF-A14x25 G2 PWM Sx2-PP to pull air out 500RPM. That's quiet enough, but barely enough airflow. Instead of pulling, I should have hidden them inside a duct behind a baffle.

I totally underestimated importance of baffles. I thought smooth airflow would be more important, but nope. Labyrinth matters more. Super important around both exhaust and intakes!

I'm oddly sensitive to fan noise. A normal person's "quiet" PC to me is still unacceptably annoying. So I (foolishly) built an acoustic enclosure for my already-Noctua-laden PC.
Lots of faff for shaving off ~5dB(A).
