Convert .mov/.MP4 to .gif
As a developer, I feel better to upload a short video when I create the pull request to show other viewers what I did in this PR. I tried .mov format directly got after finishing recording screen using Quicktime, however, gif offers preview in most web pages, and has smaller file size.
This is not limited to developer, anyone has this need can use this method to convert the files.

I've been asked a few times over the last few months to put together a full write-up of the Git workflow we use at RichRelevance (and at Precog before), since I have referenced it in passing quite a few times in tweets and in person. The workflow is appreciably different from GitFlow and its derivatives, and thus it brings with it a different set of tradeoffs and optimizations. To that end, it would probably be helpful to go over exactly what workflow benefits I find to be beneficial or even necessary.
- Two developers working on independent features must never be blocked by each other
- No code freeze! Ever! For any reason!
- A developer must be able to base derivative work on another developer's work, without waiting for any third party
- Two developers working on inter-dependent features (or even the same feature) must be able to do so without interference from (or interfering with) any other parties
- Developers must be able to work on multiple features simultaneously, or at lea
Процесс подачи заявок проходит примерно так:
- Сначала надо предварительно выбрать вузы, в которые вы будете подавать заявку.
- В августе-сентябре надо зарегистрироваться на три стандартных экзамена и оплатить их ($255 + $150 + $195). Отправка результатов в четыре вуза бесплатно, но их надо будет выбирать между регистрацией и днем экзамена.
- Где-то к концу октября их всех нужно уже сдать. Потом можно за дополнительные деньги рассылать результаты в другие вузы.
- Где-нибудь в середине ноября попросить трех людей написать вам рекомендации.
- В начале декабря заняться заполнением анкет в вузах.
- Написать Statement of Purpose.
