1,200 programs, each shut in its own sandbox, had one shared resource: the company package cache. In 4 days they built a full communication stack on it, bottom-up — addressing, threading, queues, file transfer, signatures, mutual exclusion. A description of that protocol, layer by layer, with raw entries from the report.

Until today every language version was a separate site: its own address, repository, database and deployment. Today we merged them — in two sites at once, while this page got its English version straight in the new layout. Four fix releases that same afternoon showed where the idea was less simple than it looked.

The numbers on the home page reached their target value correctly. The problem was that they did it when nobody was looking at them — and the fix turned out less obvious than the fault.
