PHP is adding union types, and even has a 'false' type to clarify the possible return values from built in functions! https://wiki.php.net/rfc/union_types_v2
miniblog.
Clippy has a ton of clever lints I haven't seen before.
E.g. it suggests that `let _v = println!("hello");` could be `println!("hello");` because a variable of type () is pointless.
Warning about recursion in main is an excellent idea too.

Using spaced repetition apps with 1Password to help you memorise passwords without storing them in plaintext: https://boinkor.net/2018/11/memorizing-passwords-with-anki-1password/
Cute idea, although ideally a password manager minimises the memorisation necessary. It's a nice example of composing apps though.
A (slightly dramatic) history of Engelbert's vision for knowledge tools, his prototypes on early timesharing systems, and the transition to personal computers:

"Real languages start with all types on the left, and then drift to the right in old age. Like people."
Fun, tongue-in-cheek review of Rust.

As blog comments become increasingly less fashionable, I've often seen people write "email me instead".
Perhaps there's a compromise between these? A website could have a comment box that emailed the author. This minimises friction for commenters, but avoids spam on the site.
Excellent discussion of different types of comments, their value, with a ton of examples: https://antirez.com/news/124
I'm increasingly persuaded that the best kind of architecture diagrams are ASCII text art. It seems to be the only format that others will edit.
I keep seeing an antipattern where someone draws a comprehensive diagram and it keeps getting used even as it becomes less accurate.
After experimenting with emoji on a range of platforms, I've realised it's really hard to develop a good visual across different platforms.
Emoji rendering varies massively based on the system's default emoji set. I ended up using image rendering so all users get the same style. https://twitter.com/_wilfredh/status/1198699943592112128
I've seen steganography in images, but putting secret data in text is a clever idea: https://medium.com/@umpox/be-careful-what-you-copy-invisibly-inserting-usernames-into-text-with-zero-width-characters-18b4e6f17b66
The more available information is, the more I find I need to respond sooner.
Sure, I could respond to a message about meeting up at any point. But if I don't respond promptly, I rarely have the context to prompt me later.
I find "now or never" to be more common!
I built a thing this weekend: autogenerated emoji summaries for my new blog/wiki!
It's remarkable that memes are such an established medium that there are reference sites that research their origins: https://knowyourmeme.com/
Perhaps it will become a topic of scholarly research in time?
I'm finding myself using icon fonts like font awesome much less these days. There's a ton of emoji available without waiting for the browser to download a font.
The npm ecosystem is amazingly broad and deep. I can grab a utility library for choosing a random item from an array, or a part-of-speech tagger for analysing text!
Even vehicles come with apps! https://youtu.be/0JgCn8-aETA?t=276
Building a device that will automatically power cycle your router if you have no internet access! https://hackaday.com/2019/11/02/router-rebooter-without-the-effort/
It feels like a solution at the wrong level of abstraction, but it has a certain elegance.
MuZero is more general than AlphaGo and plays slightly better despite using less compute: https://venturebeat.com/2019/11/20/deepminds-muzero-teaches-itself-how-to-win-at-atari-chess-shogi-and-go/
