Собаки, сдохните !

Меня бесят противные балонки, срущие и визжащие  во дворах без причин. Тем более бесят трущиеся у помоек дворняги, бульдоги и прочие тощщие и злые твари. Люблю притопить котят, если их становиться крайне много. С радостью давлю паучков, сороконожек и совсем уж массово уничтожаю комаров и мух, когда они есть. Я изобретаю точило для крыс, но никак не могу их найти.  Единственно кто от меня мог убегать это ящерки, у меня уже трофей из 3 хвостов.


Меня бесят хозяева болонок - это противные старухи или вынужденные их выгуливать их дети, которым вообще пофигу на них.


Не бойся ! кричит старушка.. она не укусит, а проклятая балонка уже с оскалом пытается дернуть штанину.


Иди к папочке, сучечка !

Интервью у веб разработчика при приеме на работу

Вопросы, которые задают при приеме на работу у WEB  разработчика/ . Интервью.

Front-end Job Interview Questions

A while ago, a group of very intelligent and experienced Front-end Developers got together and created a list of great Front-end focused job interview questions. This group consisted of @bentruyman,@ajpiano, @paul_irish, @SlexAxton, @boazsender, @miketaylr, @iansym,@vladikoff and @gf3. Since it’s creation, I’ve expanded to this list and happen to use it to help friends prepare for interviews (like my good friend Wes Bos / @wesbos) or to interview developers myself.

To note, I think that it’s only necessary to choose a handfull of questions from this list to get a good sense of a candidates capabilities and fit. The most telling questions often relate to what a person does in their free time. Asking about Twitter & Github Accounts, RSS feeds, Personal Blogs and general community involvement will tell you a lot about whether or not this person will stay up-to-date and is passionate about their work. The last group of questions will definitely let you know if the person’s got a sense of humour.

Hope this list helps some people and, if you do use it, make sure to give credit to the folks that contributed (listed above).

Note: I’ve posted this document up on Github so that you can add to it if you want. Here’s the link: https://github.com/darcyclarke/Front-end-Developer-Interview-Questions

Инопланетяне не обнаруживают нас - дураки

Люди думают почему их инопланетяне не обнаруживают. Все просто.. Для их наше появление во вселенной это маленкий всплеск активности. Точно так же и они для нас. Просто сверкнули , а потом их луна покинула или астероид пришиб. Вообщем попасть в нужное время очень сложно. Поэтому что бы увеличить шансы нужно охватить анализом на жизнь как можно больше пространства. А там глядиш можно и зафиксировать вспышку жизни. Но где хранить знания ? Ведь любая жизнь вероятнее всего будет такой короткой впышкой, а дальше конец.
