Beware when overwriting files with the same content using NSFileWrapper: the modification date can mess up.

NSTextView Bypasses performKeyEquivalent Check for Backspace and Option-Backspace

Shortcuts, aka “key equivalents”, are usually handled by views in your vier hierarchy in the same, predicatable way. Except deleting a character or word with backspace in a text view. These two, apparently, short-circuit this mechanism.

Read this introduction to Swift Concurrency. You need it.

Iterating Through Realities

Refactoring is bending reality over and over until you finally make the actual change. It’s exhausting.

Pi-hole on Unraid (as Local DNS to Access NAS Services Without a Roundtrip to Cloudflare)

My Nextcloud and a couple of other sync services are exposed to the internet via a reverse proxy, and I reach them via a Cloudflare tunnel and a custom domain. That Cloudflare round-trip doesn't make sense while I’m home, so with Pi-hole as DNS, I directly connect to my NAS for LAN speeds.

Checklists Appreciated Under Stress

Giving birth to a child includes managing stressed-out hospital staff, too. Checklists would’ve helped along the way at every turn. And they still help me to get stuff done in an otherwise unorganized daily routine.

Typed Filters and callAsFunction

Combining three Swift features for the sake of expressivitiy: sum types aka enums, callAsFunction to introduce “callable” semantics, and type extensions to beautify call sites.

The Rake and Its Prongs

We don’t think about this as we write: the blinking cursor tells a useful lie about what the text looks like, so we can work on an abstraction that is about the space between characters, and especially the space after the last character.

The Communication Tradeoff

As a software developer, I want to understand the code, so that I can implement changes for our users. How do we get there?

If You Use KOMA-Script, Really Do Use KOMA-Script

The KOMA-Script LaTeX package bundle may be typical German over-engineering, but when it works, it really works.

Fold Search Results Away in rg.el

Whenever you want to fold away content in an Emacs mode that doesn't support this out of the box, consider using outline-minor-mode. Here’s how I did that to make rg.el

You Absolutely (Do Not) Need to Comment Your Code

Comments in code are useless. And commented code is the best.

Emacs sqlite-mode to Open .sqlite Files Automatically

.sqlite files render “graphically” in Emacs, but only if you open them manually with the equivalent of a file picker dialog; that is unacceptable, and I propose a solution that opens the graphical view for SQLite database files when you visit the files automatically.

Cold-Blooded vs Warm-Blooded Software

You cannot run cold-blooded projects as warm-blooded ones. There is not enough activity “to keep the temperature up”. But cold-blooded projects are great to keep around for years and years.
