Today I learned about Java's enum types can have fields, methods and
constructors. This makes them more versatile than the enums I'm
familiar with from other languages, and unless I'm misunderstanding
something, it essentially means that they inherit from the
enum they're defined in, letting us have custom
functionality per type. I've already found a use case for that at
work, and I'm sure more is to come! More about Java's enums at
Baeldung.
Today, while reading peetseater's
blag, I stumbled across a
link to a chapter in Robert Nystrom's "Game Programming Patterns" book
on the
Command
pattern. While I had a knee-jerk reaction at first due to how many
layers of abstraction it introduces, the examples made it clear when
it might be useful to compose the code in such a way. I've yet to make
any actual games that are bigger than a few hundred lines of code, but
I'm definitely gonna be getting back to that book and checking it out
when I embark on a more serious project.
Today I learned more about how cosmic rays impact technology, and how
modern systems protect against them. I knew about the Mario speedrun
that has likely been impacted by them, but not much more than that or
the physics behind the phenomenon.
Veritasium's video
shed a bunch of light on the topic for me, I highly recommend checking
it out.
Spotless (Java formatting library) messed with my line endings a
little, and so I had to figure out a way to renormalize them in Git.
The comprehensive way to do so seems to be as follows. Firstly, set
git config --global core.autocrlf false. It might be
true on Windows by default. Secondly, configure Git's
line endings to default to LF with
git config --global core.eol lf. Lastly,
git add --update --renormalize will normalize the line
endings in every file tracked by Git.
Today I learned about
grid-template-columns: repeat(auto-fit, minmax(450px, 1fr));
which lets you easily create a responsive grid. This particular
example calculates how many 450px-wide columns can fit on your screen,
and adjusts the column count accordingly. See more on
MDN.
Today I learned about Java's Paths.get that provides a
cross-platform utility to assemble Path objects from
strings or URIs. The resulting interface contains many common methods
to work with file paths. See: documentation on
Paths.get
and
Path.
