В поисках компактного ЛБП
Я решил для разнообразия немного отойти от своих любимых тем про видеоигры и жуткие звуки музыки в них, а также и временно воздержаться от ковыряний различных Ардуин. Вместо этого обращусь к другой плоскости своих интересов: к созданию электронных самоделок. А если точнее, созданию самодельных инструментов для создания электронных самоделок.
Речь пойдёт о простейшем самодельном компактном регулируемом маломощном источнике питания, также известном среди радиолюбителей и им сочувствующих как «лабораторный блок питания» (ЛБП), собранном из подручных средств в виде готовых китайских модулей и наборов. С его помощью можно налаживать прочие самодельные творения. Конструкции подобного рода сейчас довольно востребованы, и, возможно, вам окажется полезным...

Serve a MCP Server in Google Cloud Run
Agentic AI hype is in full motion and the number of published MCP (Model Context Protocol) servers is exploding. Some years back, we joked about having a mobile app available for any purpose you can think of – today its the same with having MCP servers available for any use-case.
Given the popularity that MCP servers and building AI agents experiences, I wanted to look into how hard it would be to build the most minimalistic ‘hello world MCP server’ and deploy it as a remote MCP server with Google Cloud Run.
Google Cloud Run represents a cost-effective way of providing dockerized,...
