Hi to everyone, explanation of my sudden silence follows.
My poor old computer (it served me faithfully for six years) seems to be finally passing away. Hardware shows significant signs of exhaustion. So my current tools are mostly a screwdriver, a blowtorch and likes... 30 minutes of more or less stable uptime is what I succeeded to achieve so far.
Well, in the end, I may be able to revive it, and I may be not. If not, it'll take some time to get new one. There is no telling what time exactly all this will take. Shall try to update my status asap.
