avanavana / async-iteration.js
Last active February 6, 2021 19:34
Demonstrates two methods for iterating over arrays of data sequentially, while applying asynchronous functions to each element. The first, queueAsync(), is to be used with Array.prototype.map(), or any functor, while the second, loopAsync(), is to be used with non-functor, non-mapping 'for'-type loops.

avanavana / tzdb.sh
Last active March 26, 2021 12:51
Checks timezonedb.com to see if timezone sql and csv db files have been updated today, and downloads them both if they have. Meant to be run daily with crontab.
#!/bin/bash
# add to crontab with something like '* 0 * * * /path/to/tzdb.sh &>/dev/null'
# change the -o option's parameter to save the files in a different dir on your machine
date=`date "+%Y-%m-%d"`
if [[ ! `curl -s https://timezonedb.com/date.txt` < "$date" ]]; then
curl -s "https://timezonedb.com/files/timezonedb.{csv,sql}.zip" -o "tzdb-${date}-#1.zip"
