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

My runs in Lexington as logged by RunKeeper. GPX files of individual runs were downloaded from RunKeeper and tracks were consolidated into a single GPX file using GPS Babel. I converted the combined GPX file into GeoJSON using OGR2OGR via QGIS 2.8.1. I used MapboxJS to pull in CartoDB's Dark Matter tiles and to generally just set up the map. Finally, I used jQuery to pull in the runs.geojson.

Next steps include:

• Add a class to each path (using D3js?)
• Use that class and CSS to mess with the opacity blending on the paths (mix-blend-mode perhaps?)
• Maybe do this with Mapsense...It'd just be nice to be able to use CSS a little more naturally
• Also, let's add some title text with cool neoness!
• It might also be cool to buffer the paths, dissolve into a single polygon and toss that through [TileLayer.bound

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

Notes on my Raspberry Pi server config

This describes how I installed and configured my Raspberry Pi model B (512MB).

The Pi is mainly used as SSH jump host, IRC client, Git server, backup fileserver, etc. It doesn't need stellar performance, it just has to be cheap, low in power usage, and secure.

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.
