📂 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.

About

When using ArchLinux, I typically prefer to use an AUR helper like pacaur or yaourt to automate away the process of installing a community package.

Ansible's pacman module is great, but it doesn't support AUR packages or pacman's -U flag. Installing AUR packages with Ansible seemed to be left as an exercise to the user, and since AUR helpers do not come with a fresh Arch install, I

Moved

Now located at https://github.com/JeffPaine/beautiful_idiomatic_python.

Why it was moved

Github gists don't support Pull Requests or any notifications, which made it impossible for me to maintain this (surprisingly popular) gist with fixes, respond to comments and so on. In the interest of maintaining the quality of this resource for others, I've moved it to a proper repo. Cheers!

Every so often I have to restore my gpg keys and I'm never sure how best to do it. So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.

Method 1

Backup the public and secret keyrings and trust database

cp ~/.gnupg/pubring.gpg /path/to/backups/
cp ~/.gnupg/secring.gpg /path/to/backups/
cp ~/.gnupg/trustdb.gpg /path/to/backups/

or, instead of backing up trustdb...
