I'm becoming a pigman or finally powerfull climbing training.


It was really hard training, although I did not run a lot of traces or performed complex exercises. I just did not climb for a long time - body lost lightness, muscles became inert, blood - slow. But everything has changed - I climbed for about 3 hours, completed one new trace and couple of old traverses, and now everything is in pain - arms, legs, back, the whole body rises from the sleep.
I have tired a lot, but I feel myself just bloody excellent!

This is not an any kind of political blog, but...


Tomorrow (Nov 4) Russia celebrates "Day of people's unity", some stupid people want to change this day into nationalistic and nazi appearance.

Do not participate in idiotic "Russian march" - just be smart.
Move to the cinema, watch a video, play computer games or build an ikebana, but do not jeopardize your life and lifes of your friends.

If some persons are just idiots, it can not be changed even if you beat them in public, and some really good people suffer from such stupids.
Be smart, be gentle, be cool.

P.S. Nov 4 1612 irregulars under the direction of Minin and Pozharskiy turned out interventionists from Moscow.

My english language troubles.


I always thought that having inverted comma (') and character s after the word means some belongings to that word.
For example with following sentence 'it's property' I meant 'property of it', but actually it means 'it is property', correct is 'its property' without inverted comma after 'it'.

So don't be confused - english is not my native language (I spoke with other person in english only once (although about 4 hours), not counting simple phrases like 'where is the bus station'). Until I find some manual I will try to restructure the sentences to avoid problematic places.

Ugh, well, and definite/undefinite articles...

Netchannels roadmap.


Following issues have the highest priority in my network development process:

• netchannels wildcard support.
• NAT implementation.
• more extended userspace network stack testing.

Kevent roadmap.


I plan to implement following features in kevent in order as they are presented:

• new ring buffer implementation.
  It will be exactly like existing one, except that it will work with provided by userspace using special syscall.
  This will allow to make all kevent syscalls as so called 'cancellation points' by glibc, i.e. when thread has been cancelled in kevent syscall, thread can safely removed and no events will be lost, since each syscall will copy event into special ring buffer, accessible from other threads or even processes (if shared memory is used).
  Actually it is already possible, and it was there from the beginning of the kevent - one can provide shared memory (or memory used as shared buffer between threads) to kevent_get_events(), but in this case userspace should manage indexes (offsets where to put new ready events) by itself.
• wake-up-one-thread flag. When several threads wait on the same kevent queue and requested the same event, for example 'wake me up when new client has connected, so I could call accept()', then all threads will be awakened when new client has connected, but only one of them can process the data. This problem is known as 'thundering nerd problem'. With new flag it will be possible to mark some events, so only threads requested to be in the thundering nerd (i.e. those threads which have not set the flag on given event) would be awakened when event is ready.
• FIFO read/write notifications.
• userspace notifications. Userspace will be able to register a special event, which can be marked as ready by some other thread. In theory it is just usual pipe between users, so it is possible (and likely) that I will not do it.
• signal notifications. Unlikely to be implemented by me - I already have huge experience in 'working' with signal/rt-signal gurus, so additional project will likely mar my karma even more.
