Postgres PL/pgSQL function for UUID v7 and a bonus custom UUID v8 to support microsecond precision as well. Read more here: https://datatracker.ietf.org/doc/draft-peabody-dispatch-new-uuid-format/
-- Based off IETF draft, https://datatracker.ietf.org/doc/draft-peabody-dispatch-new-uuid-format/
create or replace function uuid_generate_v7()
returns uuid

begin
-- use random v4 uuid as starting point (which has the same variant we need)
-- then overlay timestamp
-- then set version 7 by flipping the 2 and 1 bit in the version 4 string

Tails! A tiny Forth core written as a hack for May Forth 2021, using some of Wasm3's secret optimization sauce.
// Tails has grown a bit and moved out into its own repository: https://github.com/snej/tails/

Install PostgreSQL 10 on Ubuntu

Install PostgreSQL 10 on Ubuntu

This is a quick guide to install PostgreSQL 10 - tested on Ubuntu 16.04 but likely can be used for Ubuntu 14.04 and 17.04 as well, with one minor modification detailed below.

(Optional) Uninstall other versions of postgres

To make life simple, remove all other versions of Postgres. Obviously not required, but again, makes life simple. If you have data in your previous version of postgres that you'd like to retain, then this is not recommended. Instead, you'll have to use pg_upgrade or pg_upgradecluster.

Speed up zsh compinit by only checking cache once a day.
# On slow systems, checking the cached .zcompdump file to see if it must be
# regenerated adds a noticable delay to zsh startup. This little hack restricts
# it to once a day. It should be pasted into your own completion file.
#
# The globbing is a little complicated here:
# - '#q' is an explicit glob qualifier that makes globbing work within zsh's [[ ]] construct.
# - 'N' makes the glob pattern evaluate to nothing when it doesn't match (rather than throw a globbing error)
# - '.' matches "regular files"
# - 'mh+24' matches files (or directories or whatever) that are older than 24 hours.
