Structured logs are way better than normal logs for a whole bunch of reasons, but they can sometimes be a pain to read in the shell. Take this logline for example:

{"erlang_pid":"#PID<0.1584.0>","level":"error","message":"Got error when retry: :econnrefused, will retry after 1535ms. Have retried 2 times, :infinity times left.","module":"","release":"c2ef629cb357c136f529abec997426d6d58de485","timestamp":"2019-12-17T19:22:11.164Z"}

This format is hard for a human to parse. How about this format instead?

error | 2019-12-17T19:21:02.944Z | Got error when retry: :econnrefused, will retry after 1648ms. Have retried 2 times, :infinity times left.

Docker on BTRFS is very buggy and can result in a fully-unusable system, in that it will completely butcher the underlying BTRFS filesystem in such a way that it uses far more disk space than it needs and can get into a state where it cannot even delete any image, requiring one to take drastic actions up to and including reformatting the entire affected BTRFS root file system.

According to the official Docker documentation:

btrfs requires a dedicated block storage device such as a physical disk. This block device must be formatted for Btrfs and mounted into /var/lib/docker/.

In my experience, you will still run into issues even if you use a dedicated partition. No, it seems it requires a standalone

Raspberry Pi 2/3B/B+/4B Wireless Bridge using Ubuntu Server 18.04 ARM Image and Netplan

The initial goal of this project is to use the raspberry pi in place of my Wireless Range Extender and then going from 3 wireless networks (2.4ghz, 2.4ghz extended, 5ghz) at home to only one (5ghz). This way I'm reducing the exposition to radio waves for the whole familly at home.

Let's go technical

Ok, enough drama for now, let's go technical. 😁

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).
