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

Chapter 1 - Object Oriented Design

The purpose of design is to allow you to do design later, and it's primary goal is to reduce the cost of change.

SOLID Design:

• Single Responsibility Principle: a class should have only a single responsibility
• Open-Closed Principle: Software entities should be open for extension, but closed for modification (inherit instead of modifying existing classes).
• Liskov Substitution: Objects in a program should be replaceable with instances of their subtypes without altering the correctness of that program.
• Interface Segregation: Many client-specific interfaces are better than one general-purpose interface.

Eliminating Code Smell With Grunt

by Gavin Lazar Suntop @gvn

Intro

I love clean code. There, I said it. I pride myself on passing strict linting standards and keeping my code easy to read. It's not just a personal proclivity, but a choice I hope benefits other developers.

My general experience with teams has been that code style is something people care about and have strong personal preferences. Typically, at some point people get tired of dealing with inconsistency and a standardization meeting is called. This is, of course, an important discussion to have. The problem that tends to occur is either lack of documentation or lack of enforcement of the agreed upon style. Additionally, new team members or contributors may not have access to a clear set of rules.

a simple git branching model (written in 2013)

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

Update: Woah, thanks for all the attention. Didn't expect this simple rant to get popular.
