Test design and implementation.
Test design Our test system has a pretty simple configuration, so I do not want to bother you with the detailed description of it. Simply – it’s just a standalone execution of a test.py file with all requirements (test setup and tear down) in local internal test utility. Helper local utility has a usual amount of preparation functions, test data loading and some other configurations. In the very end of test loading, it just compares a node-set result of “real” scan (software and hardware nodes in a database after the scan) with predefined node-set (from test.py). Node set we usually expect at the end of the test should be added by the developer when product discovery pattern is ready orShort Read more…

Python и vk execute = 40 тысяч постов за 3 минуты!
Да, сучка, это Python и vk execute! Собрать 39000 постов за 3 минуты! Закончил очередную партию парсеров, теперь этот парсер умеет делать сбор постов несколько быстрее, чем раньше. В прошлый раз, одними только силами Python while – мне удалось спарсить стену с 39 тысячами постов минимум за 15-20 минут, при этом с вероятностью в 50% поймать timeout error и запускать все заново или дробить сбор постов по дате или кол-ву. Вуаля, упорство и немного логики: Get posts from wall from VK wall.get Posts present: 39143| Runs: 20| Iters: 20| Offset of posts is: 2000 Posts present: 39143| Runs: 20| Iters: 20| Offset of posts is: 4000 Posts present: 39143| Runs: 20| Iters: 20| Offset of posts is: 6000 Posts present:Short Read more…

High CPU usage VMWare ESXi 5.5
Использование CPU в определенный момент начинало превышать допустимые нормы, сервер зависал и не отвечал ни на какие команды, виртуальные машины продолжали работать.
