Climbing evening.


It was OFP (in russian) or GPT (in english) - general physical training (obshaya fizicheskaya podgotovka). I do it in a bit differnet manner, instead of fixed amount of simple exercises I try to comple as much as possible in fixed time interval. This training was second one devoted to GPT, but I think result is good. For 1.5 hours I managed to complete quite a lot of exercises, but each one was completed about 80 times (8 rounds of 10 in each turn, which contains of 7 different exercises with small weights (or without) for different groups of muscles), although I wanted to complete 100 (10 rounds).
Main goal of such exercises is to increase my power endurance, since on negative slope I behave too miserable (well, not that bad, but I do want to do better).
I also bought myself new shoes, which exeeds my budget a bit, but I expect a good result from them. This time it is 'La Sportiva Viper'.

Another idea about captcha solving.


And this time it is not based on any graphic metrics.
All previous methods are similar to how small child plays with a cube, which has inlets of different forms and set of objects, each one matches only one form of inlet. Child gets objects and tries to push them into the cube via different inlets until succeded. But reading from the paper is different, instead let's recall how we were trained to draw letters and digits - draw line from one point to another, then rotate it to some degree and draw another line or arc and so on.
That is a base for my new method - each image is converted into set of control points (start of the lines, crosses (questionable though), rotates) and set of rules of how line between control points must be drawn. If that set of rules matches in some metric to database set of rules, then letter is found.
It is purely theoretic so far, but I already see how it can solve some issues with all methods I used before, but it is possible, that there will appear complex problems. For example it is not 100% clear to me how to create set of control points from given image automatically, but I have some ideas.
