Stephan Schlecht @sw7com.bsky.social · 05/10/2026Was planning to do this eventually anyway: Added LSP support to my editor. 000
Stephan Schlecht @sw7com.bsky.social · 02/10/2026In Go programs, you will occasionally find a helper function like this, especially in unit tests, where you often want to define a pointer to a literal. The reason is that the address operator & requires an addressable operand (e.g. a variable). See also go.dev/ref/spec#Add... 100
Stephan Schlecht @sw7com.bsky.social · 02/10/2026Sometimes I have thoughts like, 'I'm glad I went with a custom UIView since it made placing the gutter icons/markers easier,' only to realize a few minutes later that an NSRulerView subview would've done the job just as well. 030
Stephan Schlecht @sw7com.bsky.social · 13/09/2026Saw some computers at a museum of applied arts today, including a Robotron A 5120. It's an 8-bit computer from 1982 (up to 64 KB) that cost between 27,000 and 40,000 East German Marks. 020
Stephan Schlecht @sw7com.bsky.social · 10/09/2026The Macintosh IIfx used a 68030 chip. I found a cool browser emulator running System 7 that even features a Metrowerks C compiler. I've never seen one in real life, but according to Wikipedia, its original intro price would be equivalent to $22K today. infinitemac.org/1991/System%... 210
Stephan Schlecht @sw7com.bsky.social · 09/09/2026I've got it bookmarked in my Finder sidebar. Don't even have to open Xcode to wipe the folder. 011
Stephan Schlecht @sw7com.bsky.social · 09/09/2026Almost forgot: here is a workaround. It might not be the most elegant solution, but it's what I use. 000
Stephan Schlecht @sw7com.bsky.social · 06/09/2026Ha, ha. Indeed. I'd recommend to start with LM Studio (nice chat UI), an MoE model like qwen/qwen3.6-35b-a3b with 4-bit quantization, and a customized /.config/opencode/opencode.jsonc file. 000
Stephan Schlecht @sw7com.bsky.social · 05/09/2026I've set up an Amiga 4000 emulator (FS-UAE) and I'm just tinkering with it a bit. Emulators definitely have their own charm. 130
Stephan Schlecht @sw7com.bsky.social · 04/09/2026We had a visit from two common kestrels (Turmfalken). 000
Stephan Schlecht @sw7com.bsky.social · 01/09/2026Been tinkering with various things here and there, for fun and to learn. A few years ago, I built this (using SwiftUI for the first time). It might come in handy, as I’d like to switch my password manager for recent reasons (ofc no proprietary crypto, it uses KeePass file format). 030
Stephan Schlecht @sw7com.bsky.social · 21/08/2026Started taking a look at SwiftTerm: seems to use Metal on macOS. Wasn't necessarily expecting that. Interesting. Maybe because of scrolling performance? Or smooth resizing? I'll see. 110
Stephan Schlecht @sw7com.bsky.social · 21/08/2026Ok, so it's decided: the bar without the X it is (since it's non-modal, it shouldn't get in the way anyway.) Thx. 010
Stephan Schlecht @sw7com.bsky.social · 21/08/2026Should be done with the conflict handling, but I’m second-guessing the UI. The 'x' feels ambiguous, would it be better to just use 'Revert' and 'Keep My Version'? Also, would 'Reload from Disk' be clearer than 'Revert'? Oh, and the red tint seems a bit too subtle, should it be made more neon? 110
Stephan Schlecht @sw7com.bsky.social · 20/08/2026While we're on the subject: passing this struct as inout into a function would also be a bad idea, because you'd be violating Swift's Law of Exclusivity. 000
Stephan Schlecht @sw7com.bsky.social · 19/08/2026That's why you should avoid using reference types in structs. When assigning a value type, you expect to get an independent copy. That's not the case in this example. The invert action inverts both, since it's just a single NSBitmapImageRep that's referenced twice. 210
Stephan Schlecht @sw7com.bsky.social · 17/08/2026With my JetBrains IDE subscription, I get some AI credits automatically. I have a few days left to use them before they expire. What USEFUL things could I do with them without sending existing code to a US company? I'm open to suggestions. 010
Stephan Schlecht @sw7com.bsky.social · 15/08/2026I know this is a bit messy (I'm working on it), but error messages like this in Xcode always confuse me. Turns out I just misspelled 'drafts:'. 031
Stephan Schlecht @sw7com.bsky.social · 14/08/2026forEach is marked as mutating. body closure calls reg.remove(). This would require exclusive access. Crashes in debug build configuration, maybe author didn't notice because they only used the release config, can't say for sure. 110
Stephan Schlecht @sw7com.bsky.social · 14/08/2026Adding snapshotting here still violates Swift's Law of Exclusivity github.com/swiftlang/sw.... 231
Stephan Schlecht @sw7com.bsky.social · 12/08/2026I don't really like the title 'Draft in Current Window', need to let it sit and think about it again tonight. 000
Stephan Schlecht @sw7com.bsky.social · 11/08/2026Don't know. Read this morning, that China can continue to reduce its crude oil imports for another six months without any problems: www.wsj.com/business/ene... 020
Stephan Schlecht @sw7com.bsky.social · 11/08/2026That’s kind of how it is right now, isn't it? At least according to data from openrouter. 010
Stephan Schlecht @sw7com.bsky.social · 04/08/2026Whoa, a few days ago I read that the damage would be at $40 million, and now it's already $70 millions? Let's see what the situation looks like next week... 100
Stephan Schlecht @sw7com.bsky.social · 30/07/2026Lol. With "marketing" emails like these, you can be absolutely absolutely certain reach devs who definitely won't unsubscribe, will definitely read the article, and will 100% buy your products. What? 🤷 000
Stephan Schlecht @sw7com.bsky.social · 29/07/2026I forgot temporary attributes exist and was trying to clear temporary attributes using setAttributes. Time to call it a day. 000
Stephan Schlecht @sw7com.bsky.social · 29/07/2026Even if I restrict opening the same folder twice later, it's a good way to test the sync, like syncing changes, undo manager binding to different NSTextViews, updating word-wrap in one doc updating all views, etc. 010
Stephan Schlecht @sw7com.bsky.social · 28/07/2026For some reason, opinions on this seem to change every now and then. 🤷 011
Stephan Schlecht @sw7com.bsky.social · 25/07/2026Couldn't resist. Undo for drafts is now persisted across app restarts. Nice side effect: proves undo/redo doesn't rely on concrete object instances. 122
Stephan Schlecht @sw7com.bsky.social · 22/07/2026I was just playing around a bit; needed o run a quick test to see if a certain menu item is added by system. Much better than `swift -e ‘...’ 2>&1` on the command line for sure. (do not know where the title "Silken Couragenus" comes from, I don't even know what a "Couragenus" is.) 120
Stephan Schlecht @sw7com.bsky.social · 22/07/2026And I thought one could disable this automatic submenu entry with setting isAutomaticTextReplacementEnabled to false. Hmm. 000
Stephan Schlecht @sw7com.bsky.social · 20/07/2026After not working on it for two weeks, I'm back now and thinking about what I'd like to display under “Reveal in Sidebar” for unsaved drafts. Maybe a “Drafts” section?. Hmm. 021
Stephan Schlecht @sw7com.bsky.social · 03/07/2026That feeling when you're drilling down in Instruments to find the bottleneck, that strange mix of satisfaction at having found it and embarrassment because you really should have known about it in the first place. 130
Stephan Schlecht @sw7com.bsky.social · 01/07/2026It rained in Regensburg tonight, finally some cooling. 010
Stephan Schlecht @sw7com.bsky.social · 13/06/2026Just saw the use of `data[...]` in some code, where `data` is of type `Data`. That got me thinking: if the SubSequence type of a collection matches the type of the collection itself, using the unbounded range operator (`...`) makes no difference. github.com/swiftlang/sw... 120
Stephan Schlecht @sw7com.bsky.social · 12/06/2026Installed Golden Gate beta and Xcode beta in UTM and, of course, immediately compiled my GitChronicles app: at first glance, everything seemed to work right away, at least so far. 010
Stephan Schlecht @sw7com.bsky.social · 12/06/2026I got it working on Tahoe in UTM (App Store version) by first installing Tahoe IPSW as a guest and then installing Golden Gate Beta with InstallAssistant.pkg as an update within the guest. I don't know yet how well it works; I haven't had much time to try it out. 000
Stephan Schlecht @sw7com.bsky.social · 10/06/2026So you can restore a bricked Intel MacBook Pro using DFU (Device Firmware Update) from a Silicon MacBook. That's pretty cool. All you need is a USB-C-to-USB-C cable. Hopefully the rest will work out too. 232
Stephan Schlecht @sw7com.bsky.social · 07/06/2026Lol. Too bad it's a Snow Leopard bug fix update and not a Tiger one; otherwise, I could just install it. 110
Stephan Schlecht @sw7com.bsky.social · 07/06/2026Very nice. We had a visitor. A Green Woodpecker (Grünspecht) perched in the cherry tree in the garden. 010
Stephan Schlecht @sw7com.bsky.social · 28/05/2026I saw a green lizard today. It's a very beautiful animal. 010
Stephan Schlecht @sw7com.bsky.social · 24/05/2026Saw a Rose-ringed Parakeet (Halsbandsittich) today. 010
Stephan Schlecht @sw7com.bsky.social · 19/05/2026I'm thinking about using a minimalist interface for the title bar. Aside from the fact that the opacity of the line number gutter isn't reduced (can be fixed for sure), I'm not yet sure if that's really what I want. I need to think about it some more tonight. 030
Stephan Schlecht @sw7com.bsky.social · 15/05/2026In TextKit 2, if you only change the rendering attributes for ranges, the update either doesn’t happen at all or only occurs after a while, once you’ve scrolled a bit. One workaround I’ve found is to call setNeedsDisplay for the (sub)layers of the subviews, but there must be a better way, no? 140
Stephan Schlecht @sw7com.bsky.social · 14/05/2026Hmm, the graphs showing the changes look pretty dramatic. 010
