Solution of problems: System of heating of hands

1 year ago
It is transfer of an amusing note of Alex Papadimoulis, the founder of "The Daily WTF".

During development of the good software, we always are under pressure from several fronts at once.
First, danger is constituted by beginners who somehow could receive the first place of work, having read "Programming for teapots" the day before, before interview.
Secondly, we are threatened by the beginning careerists who could settle successfully after end of the first contract (read: received money, and the client did not condemn them for development of a useless product). Sometimes they even manage to construct career, having managed to repeat this way several times.
And at last, to eat "Uslozhniteli", or "Megareshateli" (to find successful gromkozvuchny transfer of the word "Complicators", it was not possible therefore — "Megareshateli". — a comment of the translator), one more party which entices the best of us to join them, even only on one or two micro projects.

There are people who so deeply wallowed in solutions of Mega-problems that they as if purchased a certain sixth sense: capability to find Mega-problems ("a solution which creates one more problem in the course of a solution of a real problem") in any place.

1 year ago


Without glue to the handy person in life in any way. After blow the body of favourite phone will burst, the decorative element will fall off furniture … And if in a family there are small children, then broken-down toys most often are under repair glue!

But glues all different also yield different results. I always liked epoxy glue, holds is dead. But it has two shortcomings: it needs to be parted and it long dries. And if it long dries, then to stick together difficult figures not always it turns out, it is difficult to record them until until glue grabs. And to hold adherend parts with hands 3-4 hours that still pleasure. I paid attention to glue at once Bondik when saw it.

Where to descend to the geek at the weekend and holidays in Moscow?

1 year ago
Ideal time for drawing up the list of such places is always pleasant to find in Moscow the novel cool place, days off and holidays. Here mine of top tens places, can someone will improve the list in comments:

1. Robofir-tree



If for holidays you need to descend with children somewhere, then the choice is obvious — Roboyolka in hawkers. A DIY performance in which actors and children do turning gray suits from cardboard boxes and foam rubber, and then see a performance about the kingdom of robots where the queen-mother is affected by a virus (as I understood) and she machinates to the princess, as a result that is dumped where it is found by command of robots of suspiciously reminding turtles of the ninjia. It is necessary to see this moment when the whole hall of children shouts "Reboot it", "invert the USB stick" or "do not click on this banner". You feel very old and again to young people at the same time, strange but pleasant feeling. At the end all appears well, all are rescued by a family backup. Well and unexpected appearance of Father Frost, but I did not tell it to you.

1 year ago


Attention! In the recipe with bleach danger of corrosion of metal was found! It is not recommended in standard application!

In the last publication we created cheap powder for the dishwasher from acorns and matches of the calcinated soda and laundry detergent. In this I will tell about how it is possible to improve it by means of oxygen bleach and where it is possible to purchase components for more advanced version. Let's place emphasis on efficiency of washing, but even at the same time the price will not go beyond 100 rubles/kilogram. And still there will be a recipe of a conditioner with cost value around 1 ruble for liter. As fairly noticed amarao, occupation not for all and it is simpler to much to use ready tablets. But in similar experiments with household chemicals there is something from the childhood, the first experiments on mixing of soda with vinegar and aerated water with mint candies. So the notable economy here after all is secondary. Let's have a good time) If laziness to read someone all text — at the end of a post there will be detailed recipes with recommendations.

Which of the famous musicians poorly understands the theory of music

1 year, 1 month ago


Cortney Keykbin (Courtney Kakebeen): To answer this question, it is necessary to understand that "the great musician" means. Great often call Beatles. Undoubtedly, they were excellent authors of songs. Also they were very good musicians.

Whether there were they great? It is a controversial issue. It is necessary to consider several factors at once: to improvise a variety of styles, mastery, capability and creative approach to game in general.

There are musicians who reached such level without proper knowledge of the theory of music. My favourite example – Art Tatum. He was a blind person (could not read) and learned to play a piano itself until began to attend school for visually impaired where he began to study music.
