В прошлом посте мне предрекли судьбу старухи у разбитого корыта. Комментаторы справедливо заметили: «Визионер без хард-скиллов - это просто мечтатель». Я обещал не спорить, а показать результат. Время пришло.Убираем лирику, достаем «мясо». Внутри - полный разбор архитектуры AI-платформы на n8n + Supabase + OpenAI: как реализовать рекуррентные платежи, SRS-систему повторений и генерацию PDF-дипломов, не написав и сотни строк кода вручную.

In this post there are a lot of references to the previous one – it is essential that you read it before getting down to this.In my previous posts (see the list below below) I tried to express my doubts whether there is a real physical substrate to the Lorentz transforms. The assumptions about the constancy of the speed of light, the homogeneity of space-time, and the principle of relativity... Read more ›

Коллективу Альфа-Банка и корпоративным коммуникациям больше 30 лет. За нашу историю накопилось огромное количество систем, которые внедрялись разными командами. Отпуска мы планируем в SAP HCM, командировку оформляем в SAP АХД, кандидатов ведём в E-Staff, обучение проходим в WebTutor — список внушительный. Что это значит для сотрудника? У каждой системы свой интерфейс, и нужно разбираться, где что находится. Неудобно.Неудобства проявлялись не так явно, когда команда собиралась в офисе. В нём проще... Read more ›

Я администрирую серверы на базе Astra Linux и хочу рассказать о своем видении настройки ALD домена: серверной части, клиентской, использовании файла hosts (по сравнению с DNS сервером).

Статья будет вам полезна, если вы собираетесь узнать больше о Astra Linux не только из официальной wiki. Кроме того, эту операционную систему (вместе... Read more ›

I thought my previous post rather funny, and was surprised seeing it initially receive so few views. I thought the entertainment flopped, but fortunately I was wrong. I therefore feel it my duty before my readers to address the subject of the Landau & Lifschitz proof of the invariance of the interval.You can find the summary of it in Wikipedia. Making their starting point the light-like interval always being equal... Read more ›

Even as I am posting this, I can see that my previous post received a hundred and twenty plus views, but no comments yet. I am saying again that my pursuit is not to give an answer, but to ask a question. I only wonder if there is in fact no answer to the questions I am asking – but anyway, I will continue asking them.

There is one only too obvious problem with relativity of simultaneity in the way it is normally introduced, and I have never found an answer to it – what’s more, I never read or heard anyone formulate it. I will be grateful for an enlightening discussion.The framework of the thought experiment introducing relativity of simultaneity is this. Two rays of light travel in opposite directions and reach their destination simultaneously... Read more ›

I wonder why IT developer interviews are so strange most of the time. It feels as if the people are looking for computer science teachers, not engineers. All those theoretical questions that have no relation to the working reality. It is strange to be looking for eloquent teachers, who can perfectly explain any term or pattern, and then ask them to do the actual work. Maybe it is the imprint... Read more ›
