Lsyncd Technical Session

So what is lsyncd?

Lsyncd is a tool used to keep a source directory in sync with other local or remote directories. It is a solution suited keeping directories in sync by batch processing changes over to the synced directories.

When would we use lsyncd?

So the generic use case is to keep a source directory in sync with one or more local and remote directories.

Stuff I wish I'd known sooner about service workers

I recently had several days of extremely frustrating experiences with service workers. Here are a few things I've since learned which would have made my life much easier but which isn't particularly obvious from most of the blog posts and videos I've seen.

I'll add to this list over time – suggested additions welcome in the comments or via twitter.com/rich_harris.

Use Canary for development instead of Chrome stable

~~Chrome 51 has some pretty wild behaviour related to console.log in service workers. Canary doesn't, and it has a load of really good service worker related stuff in devtools.~~

Firstly install Brew on your MAC

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Then install PHP

brew update
brew tap homebrew/dupes
brew tap homebrew/php
brew install php56

Installing Node.js with `nvm` to Linux & macOS & WSL

A quick guide on how to setup Node.js development environment.

Install `nvm` for managing Node.js versions

nvm allows installing several versions of Node.js to the same system. Sometimes applications require a certain versions of Node.js to work. Having the flexibility of using specific versions can help.

Open new Terminal window.

	# this original one uses values returned from 'brew info'
	brew list --formula \| xargs -n1 -P8 -I {} \
	sh -c "brew info {} \| egrep '[0-9]* files, ' \| sed 's/^.[0-9] files, \(.\)).$/{} \1/'" \| \
	sort -h -r -k2 - \| column -t

	# faster alternative using 'du'
	du -sch $(brew --cellar)// \| sed "s\|$(brew --cellar)/\([^/]\)/.\|\1\|" \| sort -k1h

	var Vector = function(x, y) {
	this.x = x \|\| 0;
	this.y = y \|\| 0;
	};

	// return the angle of the vector in radians
	Vector.prototype.getDirection = function() {
	return Math.atan2(this.y, this.x);
	};
