How to update the Go version

System: Debian/Ubuntu/Fedora. Might work for others as well.

1. Uninstall the exisiting version

As mentioned here, to update a go version you will first need to uninstall the original version.

To uninstall, delete the /usr/local/go directory by:

Update package.json, set version to a prerelease version, e.g. 2.0.0-rc1, 3.1.5-rc4, ...
Run npm pack to create package
Run npm publish <package>.tgz --tag next to publish the package under the next tag
Run npm install --save package@next to install prerelease package

Managing GitHub Watching

I decided to unwatch many repos in multiple organizations. Here are two scripts that I wrote to make that possible. It works like:

I load GitHubAccessToken in my environment, an environment variable that gives these access
I run node get-all-watched.js > all-watching.txt to dump all watching into a text file
Run grep "^developmentseed" all-watching > developmentseed.txt, for instance, to make a text file of only repos in the developmentseed org that I'm watching
Run node unwatch-file-of-repos.js developmentseed.txt to unwatch all those repos.

Redis 4.2 roadmap

Speed up key -> hashslot association. Now makes RBB loading 4x slower when there are many small keys.
Better multi data center story
redis-trib C coded and moved into redis-cli

Non blocking MIGRATE (also consider not using 2X memory)
Faster resharding
Bug fixing and stress testing to bring it to next level of maturity

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

Kubectl output options

Let's look at some basic kubectl output options.

Our intention is to list nodes (with their AWS InstanceId) and Pods (sorted by node).

We can start with:

kubectl get no

	console.log(1);
	(_ => console.log(2))();
	eval('console.log(3);');
	console.log.call(null, 4);
	console.log.apply(null, [5]);
	new Function('console.log(6)')();
	Reflect.apply(console.log, null, [7])
	Reflect.construct(function(){console.log(8)}, []);
	Function.prototype.apply.call(console.log, null, [9]);
	Function.prototype.call.call(console.log, null, 10);

	const MODULE_DIR = /(.([\/\\]node_modules\|\.\.)[\/\\](@[^\/\\]+[\/\\])?[^\/\\]+)([\/\\].)?$/g;

	{
	loader: 'babel-loader',
	test: /\.jsx?$/,
	include(filepath) {
	if (filepath.split(/[/\\]/).indexOf('node_modules')===-1) return true;
	let pkg, manifest = path.resolve(filepath.replace(MODULE_DIR, '$1'), 'package.json');
	try { pkg = JSON.parse(fs.readFileSync(manifest)); } catch (e) {}
	return !!(pkg.module \|\| pkg['jsnext:main']);
