This gist demonstrates the difference between threading and asyncio. To be clear, they're both limited by the Global Interpreter Lock and are both single process, multi-threaded. They are both forms of concurrency but not parallelism.
Threading (via Thread, concurrent.futures) employs time-slicing of CPU. All threads are given a slot of CPU time to do work. If the thread is blocking (sleeping or blocked on sockets), then off it goes to the next thread. With many threads that are blocked for long periods, this begins to degrade into polling (polling vs. interrupt)
Starting from VSCode v1.60, it is possible to colorize bracket pairs without using extensions, i.e natively, which is 10,000x faster that any other extension, only by setting few values in settings.json
If you want to know more on how native bracket pair colorization is developed, please refer to this official VSCode blog post that explains the cons of using an extension (such as Bracket Pair Colorizer 2) and the pros of using the native colorization option.

The Egyptian government announced in March 2023 the return of DST (Daylight Saving Time). Thus, on April, 27th 23:59:59 midnight, this announcement will have an impact on all NTP-synced networks.
To begin with, since all time calculations on NTP servers are done in UTC (Coordinated Universal Time), a NTP server does not directly deal with time zones, but it does indirectly assist in maintaining accurate time across different time zones. By using NTP to synchronize the clocks of clients with an accurate UTC reference, it ensures that clients in different time zones have a consistent and accurate time base to work from. As you should never change time manually, unless there is no other way to do it, you need to let the NTP server handle this update to sync all clients within a network.
Fortunately, the TZ database is regularly updated. On March 28th, 2023 an update release (
2023c) that handles the Egyptian DST change, was published on the inte
