Climbing evening.


Lazy-boom-slacker Grange was not able to get his ass out of traffic jam, so I climbed alone. As a result no new traces, but a number of interesting boulderings, some old traverses. As next level result I would mention damaged shoulder and leg after wild jumpings, and some interesting new starts (with couple of heavy falls from 3-4 meters high to the back).
Since I did not climb high, there were plenty of time to talk with another climbers on the floor...
It was fun training.

Distributed storing dilemma.


I have a qustion about the way data should be organized in distributed storage.
There are two possible ways:

  • sequential data is stored lineary - first storage is filled until it is full, then next one and so on. Of course error recovery codes usage requires another storages to be used, but amount of CRC data is usually noticebly smaller than amount of actual data.
  • sequential data is distributed among several storages according to some algorithm (like round-robin).
The former allows to increase random access speed, the latter - sequential access. Getting into account that even 1Gbit network has about two times faster bulk transfer speed than modern disks, priority of this issue increases.
Likely round-ribin writing is a good candidate for first implementation.
