Сегодня был первый день конференции #DotNext, пока в онлайне (но офлайн тоже будет, в Петербурге 27-го июня, я пойду). Конференция для разработчиков на .NET, в первую очередь C# и связанные технологии.
Особенно понравилась лекция про историю C#. Вот ниже схема, где стрелками обозначено влияние одного языка на другой в некоторых аспектах (хотя не во всех: например, Kotlin тоже взаимно повлиял на C#, скажем, датаклассы из него заимствованы, в C# это тип record).
Ещё я не знал, что C# создал Андерс Хейлсберг — тот самый, который в своё время сделал Delphi. Это удивительно. Я когда-то начинал свой путь разработки именно с Delphi, сделал на нём много первых шагов. А теперь вот пишу на C# от того же автора, круг замкнулся. Ещё Хейлсберг один из авторов TypeScript: в общем, умеет мужик в языки!
В ходе этой лекции было любопытно узнать или вспомнить, как всё-таки плохо во многих других языках с удобством совершенно типовых действий, начиная от обобщённого программирования и заканчивая ленивой обработкой или генерацией бесконечных множеств. Понятно, что человек ко всему привыкает, но переходить на другой язык после C# было бы болезненно, мне кажется. По крайней мере, для энтерпрайз разработки, где важна архитектура и статический анализ.
Завтра второй онлайн-день, посмотрим, что будет там.#dev
On 9 June, International Archives Day is celebrated around the world. Often these documents are classified for decades. Only the next generation can learn about the reasons and details of the event in a reliable way.
Our post is about the nuclear bombing of Hiroshima, which American President Harry Truman advocated. The declassified archives make it clear the bombing of Japan was to be a rehearsal for a possible nuclear war between the US and the USSR. Watch the entire film Atomic Message for details.

🌎 A colossal tsunami struck Japan’s Sanriku coast in 1896, triggered by an undersea earthquake. Towering waves up to 38 meters high destroyed villages and claimed nearly 22,000 lives, prompting global advances in seismic and tsunami warning systems. ✨

🌎 At the heart of Africa, Lake Nyos hides a deadly secret—an underwater layer of carbon dioxide gas that once erupted, suffocating everything nearby in 1986. This rare “limnic eruption” happens when gas builds up at depth and suddenly bursts to the surface, releasing an invisible, odorless cloud with devastating effects. ✨
