Delete Stuck Namespace

Here be dragons. Use with extreme caution.

About

This script is designed to accept namespaces as a list of arguments and will perform a namespace child resource delete loop before terminating the namespace and any finalizers.

Motivation

Just thought I'd put together some detail on deploying Tailscale using Docker and Portainer. These bits-and-pieces are available elsewhere, but not together, so hopefully this will save someone a bit of time if you'd like to add Tailscale to an existing Docker install:

Here's my annotated recommended docker-compose, to use with Portainer-Stacks. Note that I'm not using a pre-made Auth Key. I started that way, but realized it was very easy to simply check the Portainer log for the tailscaled container once the stack is running. In that log you'll see the standard Auth link that you can use to authorize the container. This way you don't need to create a key in advance, or create a reusable key that introduces a security risk:

version: '3.9'
services:
  tailscale:
    image: tailscale/tailscale
    container_name: tailscaled

Pretende usar `UUID` como PK em vez de `Int/BigInt` no seu banco de dados? Pense novamente...

TL;TD

Não use UUID como PK nas tabelas do seu banco de dados.

Um pouco mais de detalhes

const assert = require('assert')
const BLUEBIRD = require('bluebird')

const nameAsync1 = async (name) => name
const nameAsync2 = (name) => Promise.resolve(name)
const nameAsync3 = (name) => BLUEBIRD.resolve(name)
const nameSync = (name) => name

const isPromise1 = (value) => Promise.resolve(value) === value

Vim without NERD tree or CtrlP

I used to use NERD tree for quite a while, then switched to CtrlP for something a little more lightweight. My setup now includes zero file browser or tree view, and instead uses native Vim fuzzy search and auto-directory switching.

Fuzzy Search

There is a super sweet feature in Vim whereby you can fuzzy find your files using **/*, e.g.:

:vs **/*<partial file name><Tab>

Download docker-compose.yml to dir named sentry
Change SENTRY_SECRET_KEY to random 32 char string
Run docker-compose up -d
Run docker-compose exec sentry sentry upgrade to setup database and create admin user
(Optional) Run docker-compose exec sentry pip install sentry-slack if you want slack plugin, it can be done later
Run docker-compose restart sentry
Sentry is now running on public port 9000
