All information technologies in summary

The main problem of the developer, and of any IT-specialist, is that you have to constantly learn something new (it’s well written here), but there’s no time. And for each technology there is a Thick Book, setting out on a thousand pages what can be stated in ten. One gets the feeling that publishers are paying authors for the number of pages.

Citforum.ru was at one time, in fact, it still exists, only somehow it is not updated. There were articles on many then modern technologies, briefly but succinctly. I am looking for something similar, in runet or in English, where everything is brief and clear and I can not find it.
I suggest everyone to gather here links to your favorite technologies, set out in an equivalent volume of no more than 30 pages.
