Discussion of the voting system developed by the DIT of Moscow and made publicly available
Two articles have been published on Habré, offering for study and discussion a voting system, the source codes of which have recently been made publicly available and which, apparently, will be used in electronic voting on the Constitution in Moscow and Nizhny Novgorod.

About the death of dual boot and the unity of Windows and Linux (but this is not accurate)
A very controversial material came out on Habré. The author decided to abandon Apple products because of the unwillingness to depend on one vendor.

Calls to follow his example. Of course, everyone has a choice, and under the article there are already 480 comments, you can stock up on popcorn.
