Meanwhile on flat development front.


As I said, Germans know how to do the things.
Using Dronco diamond cutting wheel for corner-grinding machine and Hawera chisel I was able to create a 1.5 meters long slit in a super concrete wall with about 2x2 sm width and depth for about 20 minutes (although not without problems - some small pieces of the wall's concrete upto 1sm in diameter somehow managed to fly under my working clothes, which was not that pleasant feeling). It was so much dust in the air, that it was quite hard to detect small details in couple of meters.
And it was not quiet.
I would even say that it was loud. Very loud. Very damn bloody loud. But only for 20 minutes.
So slit for corrugation pipe for additional electricity wires for hinged ceiling is ready.
I also completed additional couple of electricity slots using drilling head, which took additional hour or so.
When dust was settled I started to fill the walls with the plaster and completed part of the kitchen corridor.

There are only couple of major things I need to complete so I could say that initial stage is over - it is electricity slit for bathroom, probably some electricity slot changes in kitchen and I need to complete to fill all walls with plaster. I suppose it will take this and next weeks, wince I will leave Moscow for weekend and will go to my sister Marina birthday.

Second stage includes complete bathroom repair: water system (boiler, filters, collectors), sewerage system, ceramic tiles and finally shower cabin and furniture. I think first two (water and sewerage systems) can be completed for one day (I even have some kind of design for them), the rest will take some time, but the main problem here is that I can not select the right colours and so on - it is even harder than selecting a tie, which was the hardest problem for me before - since I can change suits and ties quite frequently (although I rarely wear them at all), it is quite complex and expensive task to change ceramic tiles.

Third stage is floor levelling and flat clean repair (wall-papers, painting and so on), which I expect to complete this century (although optimistic plan is to complete it early in November).

More kevent benchmarks from Johann Borck.


He created kevent based web server and client and got following results:
With 20k concurrent connections it is possible to handle more than 4100 (4117) requests per second.
With 26k concurrent connections it is possible to handle slightly less than 4100 (4086) requests per second.
With 4k concurrent connections it is possible to handle about 5000 requests per second.

Hardware used for tests:
Server: Athlon 1.8 GHz (Barton 2500) 1024 MB of RAM.
Client: Sempron64 1.6 GHz 512 MB of RAM.
