Worklog: Articles and Blog Posts by Christian Tietze

Hazel was still quite new when I didn’t have a Mac and planned to get one in 2007/2008.

For a while now I’ve been working with the people at Shiny Frog – the team behind Bear – on something new.

In my teenage coding days around 2001, before I used version control systems, and for a long time, I spent a lot of time reading code just to somewhat memorize it and to know what happens where and when and how I got there.

The very first Swift Blog Carnival is a wrap.

Recently on a meetup, I was asked whether the age of manual note-taking and Zettelkasten is over now that LLM’s are everywhere and can produce so much text in such a short time that humans can’t outcompete them anymore.

I picked up a term that I have not used in all my years of programming, and I love it: “Drift”.

The April Carnival is closed.

It took me a decade to try Emacs again, for reasons totally unrelated to computer programming (task management!)

What if “bicycle for the mind” never meant that it’s a way to speed up, but a way to exercise?

Put away your Betteridge’s Law of Headlines, I genuinely don’t know the answer :) In “Training large language models on narrow tasks can lead to broad misalignment”, Betley et al found that fine-tuning LLM’s with e.g. insecure coding practices can affect…

In November, I posted how to make Claude Code mark itself as the author of git commits.

Agentic engineering practices changed from “you should commit everything yourself” to giving the agentic tools more autonomy for example in order to try out different things to implement a change.

Shout-out to FreeBSDKit: FreeBSDKit provides idiomatic Swift, C and C++ interfaces to FreeBSD’s unique system features including Capsicum sandboxing, jails, process descriptors, kqueue-based signal handling, and inter-process communication with descriptor…

Over on the Zettelkasten forums, Edmund Gröpl, in a post: “On Zettelkasten Productivity”, proposes to reframe the “how many books have I written” lifetime achievement number as “how many books have grown out of what I read”, showing how small the ‘tip’ of…

I really, really don’t like how I get ebooks onto, and notes off my Supernote e-ink tablet.

Completion within Emacs is not just about “intellisense” auto-completion as you type, or tab-completion in command prompts.

Tony Arnold shared a video by Dr.

I noticed that in all terminal emulators I tried (iTerm, Ghostty, kitty), I rely on a system-global shortcut to show me a session that I use whenever I need to terminalize something right now, right there, like ffmpeg something or bulk delete with a patte…

The Xcode 26 System Prompts collection contains a couple of chat templates, but more interestingly: typical LLM-targeted documentation of new-ish technology to prime their context for stuff that’s not well-represented in training data.

I was reading the SendableMetatype docs because the new NotificationCenter messages I was catching up on use that in the API headers.
