With some luck, all my Windows programming wet dream might actually come true one day. There's progress on making Swift available on Windows, and there's progress on providing a Win32 API wrapper for Swift so you can share model code across platforms and write UI for Windows and Mac separately.

After a couple weeks of experimentation, I find that twice weekly email delivery of my recent blog posts is one too many. I wrote a lot in the past months, so each issue contained quite a few links.

Rich Siegel recently wondered on Slack why NSTextView would suddenly display empty placeholders for some glyphs when the font does not support them, instead of falling back to a safe font like it usually does. Chinese characters never got displayed. Michel Fortin remembered a similar problem, and the potential fix was quite simple:
