Falsehoods Programmers Believe About Names

So, as a public service, I’m going to list assumptions your systems probably make about names.  All of these assumptions are wrong.  Try to make less of them next time you write a system which touches names.

One of my favourite programming articles of all time.

Still thinking about how to solve the “posting a digest of interesting links today” problem.. In the meantime I'll post them on my website, not showing on the homepage but under https://vandragt.com/content/bookmarkedpages/

Opinion pieces used to be more insightful than the news. Now they’re just more ridiculous. Research the subject instead, you will be better informed than the people writing these articles.

Countdown - a bash countdown timer

1 min read

I was looking for a tea timer countdown but quickly realised I might as well use a countdown script for this. I based my script on the linked script but added a customizable notification at the end

$ nano ~/bin/countdown
#!/bin/bash
# v2 - 2019-05-01
secs=$1
msg=${2:-$1 seconds passed.}
while [ $secs -gt 0 ]; do
echo -ne "$secs\033[0K\r"
sleep 1
: $((secs--))
done
notify-send 'Countdown Finished' "$msg"

$ chmod +x ~/bin/countdown
$ countdown 180 "Tea is ready."

Our society is sleep deprived

“Sleep loss will leak down into every nook and cranny of your physiology,” he said. “Sleep, unfortunately, is not an optional lifestyle luxury. Sleep is a nonnegotiable biological necessity. It is your life support system.”

I'm looking forward to reading Matthew Walker's book on the topic.

macOS doesn't use a swap file when running from an external SSD

1 min read

So I was seeing graphical glitches, freezes and Activity Monitor indicated memory pressure. Turns out macOS doesn't mount a swap file, as I am running from an external SSD install.

This is easily fixed. I can't believe it is a problem though.

By the way I had to change the end of line 4 (because the command in the Ask Different answer returned multiple results) to:

VM_VOLUME=$(/usr/sbin/diskutil list | grep "VM" | awk 'NR==1{print $7;exit }')

It's easy to add the launch item using Lingon X and start it with sudo ./mountvm.sh for the current session.

DarwinMailApp gives us all a lesson in customer service in this thread: https://news.ycombinator.com/item?id=19705440 His tone is exactly right, and encourages more follow-ups as a result. Well done!

Stop OpenPGP passphrase prompting on login

1 min read

As a security conscious person I setup my OpenPGP keys with a passphrase, however on OpenSUSE Leap 15 this causes a login prompt to appear that delays the network connection from initiating. The same issue also blocks software updates and means a browser restart due to DNS cache stopping connections to websites. This is fairly annoying.

It turns out that this can be fixed by sharing the network connection via Connections > open the connection > General Configuration > All users may connect to this network. This causes NetworkManager to cache the required  authorization tokens (this is my understanding).

Note that other software such as Kontact might set a daemon to startup by default, causing the same prompt. This can be unticked in its settings.

If everything else fails, then you could remove the passphrase for the PGP key but this is not recommended as this means someone can take on your identity should your key be exposed for any reason.
