No demos yet on Pushkin square but a ton of police in riot gear. They picked up two guys and threw them in a bus. The entire square is protected by crowd control barriers. Felt like there were lots of people just kind of milling about waiting for something to happen. πŸ‡ΊπŸ‡¦.

Does anyone know of server farms that support various platforms? Like, I want 10 VMs running MIPS/Linux, another 10 running x86_64/Windows, etc? Think: where do I run millions of tests for my compiler on all architecture/OS combinations?.
