Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

There are always 24 hours in a day.
February is always 28 days long.
Any 24-hour period will always begin and end in the same day (or week, or month).

Unofficial Bash Strict Mode

Sometimes a programming language has a "strict mode" to restrict unsafe constructs. E.g., Perl has use strict, Javascript has "use strict", and Visual Basic has Option Strict. But what about bash? Well, bash doesn't have a strict mode as such, but it does have an unofficial strict mode:

set -euo pipefail

set -e

Connecting to an Android device over SSH

Initial Setup

Install Android App Termux from APKPure or AppStore. If the app exists, just delete and re-install it to get the latest version, The APK can be downloaded from https://apkpure.com/termux/com.termux/ Install the APK using by running

adb install ~/Downloads/Termux_v0.73_apkpure.com.apk

Say you want to listen to youtube videos as a podcast but you're too stubborn to use the AWS instant install thing on the podsync home page.

Before you start: if you're using Pocket Casts you'll want to make sure this all works before adding the podcast. Pocket Casts will cache your podcasts and then if you goofed it will always be referencing the non-working podcast. You can fix that by changing the subdomain you use. But it's just easier if you get it right from the start. You can test that it works by using something like Apple Podcasts, which will not cache and will just work if it works.

I'm kind of expecting that you're comfortable (though not necessarily experienced in) logging into your router, accessing the terminal and doing git commands, managing domain names, and that docker works on your system.

👾 Error

fatal: detected dubious ownership in repository at '/storage/emulated/0/<some_folder>'
To add an exception for this directory, call:

        git config --global --add safe.directory /storage/emulated/0/<some_folder>

🤔 Why do I see this error ?

This is a simple check (by Git) comparing current user ID and the ID of the owner of the current folder. If they do not match (in case of rootless Termux, root owns them all.), Git will not permit any action (even git status).
