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.

  • elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent
  • elem.clientLeft, elem.clientTop, elem.clientWidth, elem.clientHeight
  • elem.getClientRects(), elem.getBoundingClientRect()

Distributed Systems Papers
View papers.md

(dominic: this list of papers was originally recommended to me by Brain Noguchi @bnoguchi, and was a great start to understanding distributed systems)

Here's a selection of papers that I think you would find helpful and interesting:

Time, Clocks, and the Ordering of Events in a Distributed System

The seminal paper about event ordering and concurrency. The important result is that events in a distributed system define a partially ordered set. The connection to what we're working on is fundamental, as this defines how to detect concurrent updates. Moreover, the chosen algorithm to turn the partially ordered set into a totally ordered set defines the conflict resolution algorithm.

What I Wish I'd Known About Equity Before Joining A Unicorn

Disclaimer: This piece is written anonymously. The names of a few particular companies are mentioned, but as common examples only.

This is a short write-up on things that I wish I'd known and considered before joining a private company (aka startup, aka unicorn in some cases). I'm not trying to make the case that you should never join a private company, but the power imbalance between founder and employee is extreme, and that potential candidates would

Pagination 101

Article by Faruk Ateş, [originally on KuraFire.net][original] which is currently down

One of the most commonly overlooked and under-refined elements of a website is its pagination controls. In many cases, these are treated as an afterthought. I rarely come across a website that has decent pagination, and it always makes me wonder why so few manage to get it right. After all, I'd say that pagination is pretty easy to get right. Alas, that doesn't seem the case, so after encouragement from Chris Messina on Flickr I decided to write my Pagination 101, hopefully it'll give you some clues as to what makes good pagination.

Before going into analyzing good and bad pagination, I want to explain just what I consider to be pagination: Pagination is any kind of control system that lets the user browse through pages of search results, archives, or any other kind of continued content. Search results are the o

Generators Are Like Arrays
View generators.md

In all the discussions about ES6 one thing is bugging me. I'm picking one random comment here from this io.js issue but it's something that comes up over and over again:

There's sentiment from one group that Node should have full support for Promises. While at the same time another group wants generator syntax support (e.g. var f = yield fs.stat(...)).

People keep putting generators, callbacks, co, thunks, control flow libraries, and promises into one bucket. If you read that list and you think "well, they are all kind of doing the same thing", then this is to you.

You can’t perform that action at this time.
