Debugging Poltergeist and PhantomJS
Recently at Opensight we had weird issue with our integration tests. When we run single test it succeeds, but when whole suit it fails.
It was failing on the same "terms and conditions" page where we expect 'Accept' button: could not find element Accept

Психологическое айкидо
Когда тебя бьют, не уворачивайся, а подставь плечо и используй силу удара чтобы опрокинуть противника и положить его на лопатки.
Средство от бедности
Люди разные.
Мир не обязан быть удобным.
Не бойтесь совершенства - вам его не достичь.
Лучше быть последним на растущем рынке, чем первым на убывающем.
- Дорогой, у твоего сына будет ребенок.
- Это его проблемы
- Но от твоей любовницы.
- Это ее проблемы.
- А что же ты собираешься делать?
- Это мои проблемы.
- Мне все надоело, и я от тебя ухожу.
- Это твои пробелмы.
Non-Violent Communication: A Language of Life, Second Edition
book by Marshall B. Rosenberg
This is one the best books I've ever read. I've read few dozens of self improvement and psychology books, but did not have a clue what this book is talking about. I would recommend it to everyone, including teenagers.
I did a small experiment and after reading each chapter I've created a summary list of highlights, first as a lesson for me to revisit each chapter and short list I could come back to in the future.

Differentiate your gem
Are you tired of seeing yet another project on github while there are ten others which do exactly the same thing? In this post I suggest we start to diffirentiate our projects.

And better be alone than with whoever.
The most valuable skill of a successful entrepreneur
isn’t vision or passion or a steadfast insistence on destroying every barrier between yourself and some prize.
Rather, it’s the ability to adopt an unconventional approach to learning: an improvisational flexibility not merely about which route to take towards some predetermined objective, but also a willingness to change the destination itself. This is a flexibility that might be squelched by rigid focus on any one goal.

Деминг, Уильям Эдвардс
"Деминг учил, что путём принятия соответствующих принципов управления организации могут повысить качество и одновременно снизить расходы (за счёт сокращения количества отходов, переделывания, изнурения персонала и судебных разбирательств, при одновременном повышении лояльности клиентов). Ключ в том, чтобы практиковать непрерывное совершенствование и представлять производство как систему, а не как кусочки и части."

Speed up POW DNS Lookup
I'm using POW as a proxy to my local dev server in development. That gives me nice local *.dev domain names. However I've noticed that it takes 10 seconds to load a singe page in Chrome. Of course, I thought, It does like 80 requests as each asset is served as a separate file in development. But after investigating it a bit more DNS lookup for each request was 3 seconds and for some reasons it was like that for every single http request.
Report rake (>=0.9) exceptions to NewRelic
NewRelic service is great for application monitoring and errors tracking. However it doesn't track rake exceptions by default. You can use AirBrake gem and service, but sometimes it's too much for you. Fortunately with a bit of ruby it's easy to do it yourself.

In biology, Bateman's principle is the theory that females almost always invest more energy into producing offspring than males invest, and therefore in most species females are a limiting resource over which the other sex will compete. It is named for English geneticist Angus John Bateman (1919–1996).

Homogamy is marriage between individuals who are, in some culturally important way, similar to each other. Homogamy may be based on socio-economic status, class, gender, ethnicity, or religion.[1] It is a form of assortative mating.
The Scarcity Principle
The Ben Franklin effect is a psychological finding: A person who has done someone a favor is more likely to do that person another favor than they would be if they had received a favor from that person. Similarly, one who harms another is more willing to harm them again than the victim is to retaliate.

The bigger the lie, the more people will believe it
If you tell a lie big enough and keep repeating it, people will eventually come to believe it. The lie can be maintained only for such time as the State can shield the people from the political, economic and/or military consequences of the lie. It thus becomes vitally important for the State to use all of its powers to repress dissent, for the truth is the mortal enemy of the lie, and thus by extension, the truth is the greatest enemy of the State.
