Tiles were comparably slow to draw. Windows 3.1 and maybe more recent Windows had a background option called "patterns". These are 8x8 patterns of black-over-something. Second color is customizable. It could be white, but also something else. EGA/VGA hardware specific is that 8 pixel wide repeating stuff can be drawn relatively quickly. Patterns were not inside files. They are probably inside registry? Or ini files?
Whatever. The end result is that patterns are forgotten and omitted from retro background collections.
When I could run Windows 3.1, I had no multimedia thing. I have found PC Speaker driver somewhere, and it could play event sounds like start-up, but could not play in ordinary player. Same WAV in player won't play because it is not "event sound". And no MIDI of course. Windows 3.1 was somewhere around, but it was nothing to do there. Graphics on EGA was slow. Windows 3.1 was telling us: if you want your programs to work fast, write them for bare metal, and we were using bare metal programs in DOS and writing bare metal programs for DOS.
First time I heard MIDI was Windows 98 already. Graphics of Windows was still slow compared to DOS, but Windows 98 offered more experience. Other developers were raising questions why do they write slow programs for Windows when they could write fast programs for DOS. From times of sound card arrival I recall that there was a bridge between CD-ROM and soundcard, and DOS Navigator could control playback of CD tracks, and that was they way we had music for ordinary activity.
Most memories about MIDI are related to custom Duke Nukem 3D maps. Custom maps sometimes included custom graphics in ART files and custom music in MIDI format. Duke Nukem 3D is the most recognized MIDI player. In Windows I could download Macromedia Flash file, observe the slide show, think "guys, when will you learn to program?" Exit Windows, run Duke Nukem 3D, wonder why can some programmers deliver real time 3D graphics, and other programmers cannot even draw 2D. Oh, and MIDI plays in the background because Duke Nukem 3D music is MIDI.
> unable to keep its own top tech talent supportive of their own government
Government did much to turn them away. And with regards to Makh messanger. Patriotic tech talents are supposed to be interested in Elbrus 2000 PC and Aurora mobile OS. Does Makh messenger work on something Russian? No, Makh does not work on anything Russian. So what makes Makh Russian? We don't get it. It's some another Russia that we don't belong to. Our Russia is Elbrus 2000 PC and Aurora mobile OS. And software from Astra group. People behind Elbrus 2000 support orthodoxal christianity, and people behind Astra group are for great Soviet past. They call one of Astra Linux releases "Leningrad". The proper name of what is currently known as "Saint-Petersburg."
Makh is from some commercial group that does not care about our values. Virtually openly violates traditional values. They are from VK group, and VK hosts VKFest, an open air for youth with rotten words, furnication songs, all that stuff.
Our Russia and their Russia don't mix like water and oil.
For military there is another communication network called Свод (Svod, Arch). It was 4 years late to the party, but at least goes in now.
I would say they are trying to block every public VPN, and if some VPN tried to hide behind CloudFlare's backs thinking that they took all CloudFlare sites as hostages, then whole CloudFlare is nuked, and hostages did not save VPN from blocking.
YouTube is easily accelerated via DPI bypass. It used to work with CloudFlare too, but not anymore, so CloudFlare is banned more hard than YouTube. With DPI bypass YouTube is very fast.
There is a real world alternative to Markdown. Ada programming language standard is defined in a text format that is converted to TXT, HTML and PDF. Tools can compare different Ada standard versions, sometimes several versions, producing multi colored documents.
LibreOffice can export into PDF with embedded source document. This PDF can be opened for editing in LibreOffice. I think, they should make more use of this feature. Signature can be applied to PDF half which is definite enough
