set -e, -u, -o, -x pipefail explanation

set -e, -u, -o, -x pipefail

The set lines

  • These lines deliberately cause your script to fail. Wait, what? Believe me, this is a good thing.
  • With these settings, certain common errors will cause the script to immediately fail, explicitly and loudly. Otherwise, you can get hidden bugs that are discovered only when they blow up in production.
  • set -euxo pipefail is short for:
set -e
set -u

How we incorporate next and cloudfront (2018-04-21)

Feel free to contact me at [email protected] or tweet at me @statisticsftw

This is a rough outline of how we utilize next.js and S3/Cloudfront. Hope it helps!

It assumes some knowledge of AWS.

FeathersJS: Better permissions

Better Permissions Control

We have introduced 3 new hooks and 2 new middleware as part of feathers-permissions that give you much more flexibility and control over access permissions than was previously possible. Permissions are stored in the database on the entity record that needs to have access permissions checked (typically a user). They look like this:

[
    '*', // all services, all methods, all docs
    'users:*', // all methods on users service
    'users:remove:*', // can remove any user
    '*:remove', // can remove on any service

Trello CSS Guide

Hello, visitors! If you want an updated version of this styleguide in repo form with tons of real-life examples… check out Trellisheets! https://github.com/trello/trellisheets


Trello CSS Guide

“I perfectly understand our CSS. I never have any issues with cascading rules. I never have to use !important or inline styles. Even though somebody else wrote this bit of CSS, I know exactly how it works and how to extend it. Fixes are easy! I have a hard time breaking our CSS. I know exactly where to put new CSS. We use all of our CSS and it’s pretty small overall. When I delete a template, I know the exact corresponding CSS file and I can delete it all at once. Nothing gets left behind.”

You often hear updog saying stuff like this. Who’s updog? Not much, who is up with you?

nodejs clustering, zero downtime deployment solutions

Clustering: The basics

The trick? pass the file descriptor from a parent process and have the server.listen reuse that descriptor. So multiprocess in their own memory space (but with ENV shared usually)

It does not balance, it leaves it to the kernel.

In the last nodejs > 0.8 there is a cluster module (functional although marked experimental)
