It is appalling that PLC devices are connected to the Internet. I get why it happens, a former company I worked for had a vendor install an SCADA + HVAC system, networking provided a standard drop without configuring the specific restricted VLAN. That system was open to the internet with the default password as "password." No one checked the network other than active connectivity and the system was put on the internet.
For water and power companies it is unbelievably negligent to connect SCADA to the Internet. There should be no reason why we need task force, after task force to solve this entirely self owned problem. This was a problem back in the early 2000s and systems are still placed on the Internet.
What is a solution? How about a private network between utility companies with encrypted traffic, not connected to the open Internet. If Internet monitoring is required, configure a very secure VPN to a DMZ.
Water system controllers don't belong on the internet, says ex-NSA chief after suspected Iran attacks

Questions for people who control their environmental temperatures with heat pumps (and only people with first-hand experience):
1. What is the optimal operating temperature range for your heat pump? (I.e., lowest temp it operates in efficiently for heating, highest temp for cooling)
2. When you can't use it because temperatures are outside that range, what do you use a back-up heating and cooling alternatives?

I keep reading about Corsi–Rosenthal boxes as DIY air purifiers that outperform all commercially available air purifiers.
You literally only duct-tape four HVAC filters together and slap any regular PC fan onto them.
US-Americans recommend the brand #Filtrete for MERV-rated HVAC filters, but in Europe that brand costs at least twice or thrice as much as in the USA.
Are there any equivalent affordable HVAC filters in Europe with a MERV rating of 8 or 13? Or do I simply have to swallow the additional cost because HVAC filters aren't as ubiquitous in Europe as they are in North America?

In the Canadian Smokestream right now! Graph from #HomeAssistant, showing PM2.5 readings. Outside is from the nearest station reporting to #WAQI, inside from #IKEA Vindstyrka. At 8pm, I switched from washable HVAC filters to MERV10 disposables. Around midnight, turned on #CorsiRosenthalBox, full speed. (Same room as sensor.)
So, #hvac was doing ok, MERV10 improved it. The CR really made a big difference, and quickly, lowering the level about 2.5x. -

Хотел написать регулятор для руфтопа. Пришлось решать дифференциальные уравнения
В прошлый раз я писал про голосового ИИ на Asterisk и Яндексе. Фурора не случилось, но статью открыли семьсот с лишним человек, в ленте её увидели тысячи, а в комментариях нашлись те, кто делает ровно то же — с той же болью и теми же вопросами про задержки и оценку качества ответов. Значит, тема живая, и про свои проекты писать имеет смысл. Сегодня — про другое, с виду куда более скучное: регулятор для руфтопа. Руфтоп — это крышный кондиционер, большой ящик на крыше торгового центра. Логика — по сути термостат с амбициями: держи температуру, включай компрессоры по запросу, не дай им зачастить. Я закладывал пару недель. Кончилось это системой дифференциальных уравнений с собственным движком, которая пять раз убедила меня, что всё работает, а потом оказывалось — неправильно. А главное — кончилось не регулятором вовсе. Регулятор оказался тривиальным. Настоящая работа была в другом: научить систему честно говорить, что с железом не так, — и не соврать при этом ни одной цифрой. Голый тезис на весь текст: термостат — это просто, пока не спросишь, что физически происходит внутри. После этого вопроса начинается наука. А приборы, которые показывают «всё в норме», врут убедительнее всего — и заставить их не врать труднее, чем написать сам регулятор. Читать и пить кофе
