Originall From: Posted 2015-05-29 http://ubwg.net/b/full-list-of-ffmpeg-flags-and-options

This is the complete list that’s outputted by ffmpeg when running ffmpeg -h full.

usage: ffmpeg [options] [[infile options] -i infile]… {[outfile options] outfile}…

Getting help:
    -h — print basic options
    -h long — print more options
    -h full — print all options (including all format and codec specific options, very long)

How to setup AWS lambda function to talk to the internet and VPC

I'm going to walk you through the steps for setting up a AWS Lambda to talk to the internet and a VPC. Let's dive in.

So it might be really unintuitive at first but lambda functions have three states.

1. No VPC, where it can talk openly to the web, but can't talk to any of your AWS services.
2. VPC, the default setting where the lambda function can talk to your AWS services but can't talk to the web.
3. VPC with NAT, The best of both worlds, AWS services and web.

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

console.log wrap resolving for your wrapped console logs

I've heard this before:

What I really get frustrated by is that I cannot wrap console.* and preserve line numbers

We enabled this in Chrome DevTools via blackboxing a bit ago.

If you blackbox the script file the contains the console log wrapper, the script location shown in the console will be corrected to the original source file and line number. Click, and the full source is looking longingly into your eyes.

/**
 * Fancy ID generator that creates 20-character string identifiers with the following properties:
 *
 * 1. They're based on timestamp so that they sort *after* any existing ids.
 * 2. They contain 72-bits of random data after the timestamp so that IDs won't collide with other clients' IDs.
 * 3. They sort *lexicographically* (so the timestamp is converted to characters that will sort properly).
 * 4. They're monotonically increasing.  Even if you generate more than one in the same timestamp, the
 *    latter ones will sort after the former ones.  We do this by using the previous random bits
 *    but "incrementing" them by 1 (only in the case of a timestamp collision).

Tools that read through a directory, stream or tree and create an Application Cache manifest for you.

AppCache is still a douche but luckily there are tools available to take the pain out of generating your initial manifest files:

• Grunt: grunt-manifest is currently the de facto option, but the project lead is looking for a new maintainer. In light of that grunt-appcache is an alternative in case you're looking for more active support.
• Gulp: gulp-manifest is inspired by grunt-manifest and has a similar set of options.
• Broccoli: broccoli-manifest brings manifest file compilation based on trees.

Do review what is generated. As with any automation tooling, be careful that what is being generated is what you actually intend on being cached. I generally rel

Nesse artigo vou mostrar rapidamente como tirar um Print Screen da página inicial de seu site utilizando diversos dispositivos. Algo que pode facilitar e muito a vida caso esteja desenvolvendo uma página responsiva.

Nesse exemplo vamos utilizar o NodeJS e o Selinium 2. As outras dependências necessárias estão especificadas no arquivo package.json. Arquivo que é usado para fornecer ao gerenciador de pacotes NPM informações de como lidar com as dependências do projeto, a descrição do projeto, a licença utilizada, dentre outras.

Para facilitar nossa vida vamos utilizar um serviço de Cloud do SauceLabs. Esse serviço permite utilizar diversos tipos de navegadores. Logo logo
