Adopted from here https://topaxi.codes/use-npm-without-root-or-sudo-rights/

I'm saving this as a gist and modifying it to ensure that if the original blog post disappears it lives on somewhere.

Added some notes for Ubuntu 18.04 and similar.

Today we're going to setup our npm installation to be used without root or sudo rights.

By default, if you install packages globally with npm, npm tries to install them into a system directory (i.e. /usr/local/lib/node_modules). With the next steps, we're going to use your home directory for those files.

Dealing with the Linux OOM Killer at the program level

Do this in cases when you dont want to change the os-level settings, but only want to disable the OOM killer for a single process. This is useful when youre on a shared machine/server.

The OOM killer uses the process level metric called oom_score_adj to decide if/when to kill a process. This file is present in /proc/$pid/oom_score_adj. The oom_score_adj can vary from -1000 to 1000, by default it is 0.

You can add a large negative score to this file to reduce the probability of your process getting picked and terminated by OOM killer. When you set it to -1000, it can use 100% memory and still avoid getting terminated by OOM killer.

📂 Minimize allocations in Go

A collection of tips for when you need to minimize the number of allocations in your Go programs.

Use the go profiler to identify which parts of your program are responsible for most allocations.

⚠️ Never apply these tricks blindly (i.e. without measuring the actual performance benefit/impact). Most of these tricks cause a tradeoff between reducing memory allocations and other aspects (including e.g. higher peak memory usage, higher CPU usage, lower maintainability, higher probability of introducing subtle bugs). Only apply these tricks if the tradeoff in every specfic case is globally positive.

Quick Terraform script to deploy Gitlab runner with docker onto Hetzner Cloud (Hcloud)

1. Create other terraform stuff

• tf-backend,
• creds.auto.tfvars with hcloud_token
• ssh key: mkdir keys; ssh-keygen -f id_rsa

2. modify cloudinit.yml:

• change gitlab url
• ADD_YOUR_REGISTRY_TOKEN -> Set to the Gitlab Runner Registration Token
• Add more allowed images/services, if using gitlab registry, like that: registry.myinstance.com/administrators/docker-images/*, change base image etc.
