I know that the Stack Overflow in Russian and Russian Language (in Russian) sites were imported from hashcode.ru, a Russian-language clone of Stack Exchange. Given that the company's website http://sezn.ru/ redirects to Stack Overflow in Russian and based on what's been said here on meta, it appears that SE has acquired that company.

However, I noticed that there are currently two sites, a Math site (http://math.hashcode.ru/) and a Physics site (http://phys.sezn.ru/), that have not been imported.

Are there plans on importing those sites, or will they be run as separate sites? Is SE involved in running those sites? What's to become of them?

  • MSDN.WhiteKnight highlighted the situation very well. Could you please tell me if you still have any questions?

  • @NicolasChabanovsky It lacks discussion on the Physics site, plus it does not conclusively refer to what the future plans are (it just has speculation). Also, why was the decision made to import the Russian (in Russian) site to Stack Exchange 2.0, instead of all three former non-SO sites being hosted like the Math and Physics sites? It would be best if there were an official answer that confirmed the community answer. Oct 10 '18 at 13:34

MSDN.WhiteKnight highlighted the situation very well. Just a few extra notes:

What sites did we import?

It was a two-step decision.

  1. Evaluation of a site. SE employees went through each site and checked how much content complies with the SE rules (e.g. plain homework questions aren't allowed).
  2. Discussion with the community. After the evaluation, I contacted a community or its top users and asked them what they want: either delete the portions of the site that do not meet the SE rules and migrate to the SE 2.0 platform, or leave it as is.

As a result, the Russian Language site was imported, and the Mathematics site wasn't. As I said and MSDN.WhiteKnight quoted:

Mathematics users did not agree to throw away a large part of the site and change the rules regarding homework.

There is a very strange story with the Physics site. Before joining SE, we had ten Q&A sites in the Russian language. Most of them were too small. After the migration, we switched them to a read-only mode, and then after a few years shut them down. For some reason, I forgot to switch the Physics site to read-only mode. When it was time to shut the sites down, I realized that there were still some active users on that site.

Any plans for the future?

No plans. Occasionally I do some maintenance on the server but nothing more.


From https://vc.ru/story/11103-knowledge-network-stack-overflow

Спустя два года — в июне 2015 года — стало известно, что Stack Overflow выкупила «Сеть Знаний». Основатель компании Николай Чабановский перешёл на работу в Stack Overflow, а сама база вопросов и ответов оказалась частично перенесена на новый движок.


Two years later — in June 2015 it became known that Stack Overflow bought the "Knowledge Network" (sezn.ru). The company's founder Nicholas Chabanovsky got a job in StackOverflow, and the base of questions and answers was partially ported to a new engine.

From https://chat.stackexchange.com/transcript/22462?m=35595293#35595293

У нас есть сервер компании, к которому на самом деле доступ только у меня есть. На нем Математика крутится.

На этом сервере раньше работал ХэшКод и вся Сеть Знаний. Затем мы мигрировали что–то, что–то закрыли. Осталась только Математика, которая активна, но там одна домашка. Участники Математики не согласились выпиливать пол сайта и менять правила, запрещающие ДЗ. Как результат, сайт остался на старом движке. Поэтому компания поддерживает старый сервер.


We have a company's server that only I actually have access to. That's where Math site is hosted.

This server used to run Hash Code and the entire Knowledge Network. Then something was migrated, something closed. Only Mathematics remained active, but it consisted largely of homework questions. Mathematics users did not agree to throw away a large part of the site and change the rules regarding homework. As a result, the site remained on the old engine. Therefore, the company supports the old server.

So, it looks like StackExchange is actually involved in these remaining *.sezn.ru sites, but there are no plans on porting them to SE engine or actively developing them. They are just maintained as is.
