Latest of Changelog

GCC Dangling Reference Detection

, .

I understand why GCC guys added checks for dangling references, but without a Rust-like syntax for annotating lifetimes of references, they’re confusing and produce way too many false-positives. The situation is bad, because you should trust compilers, even more than yourself, and now instead of acknowledging and fixing our mistakes, we’re going to spend time checking if compiler is right or not. This has uncanny resemblance to the current situation with AI which you cannot trust.

Upiorek

, .

Anna Studniarek is Polish translator for most of Cosmere books, but not for Mistborn, which was translated by Aleksandra Jagiełowicz. I think that she initially planned to translate (some of) names to their Polish equivalents, similar to what Jerzy Łoziński had done with The Lord of the Rings, (sidenote: n.b. negative feedback which Łoziński’s translation received is probably the reason for most Polish translators to think twice before they change any original name.) but she changed plans. She left a single unnoticed “Upiorek”, a translation for the name of one of characters, Spook. (sidenote: “spooky” can be translated as “upiorny”) It’s one of these things you start noticing when you re-read books, but it still took me a minute to connect the dots.

Ledgerify 0.2.2

, .

I released Ledgerify 0.2.2. It has only one fix: it stops complaining about transactions with 2 postings with different currencies and different signs, but instead it correctly recognizes them as currency exchange.

i3a-scale-cycle

, .

I added a new script to i3a: i3a-scale-cycle. This allows to use a single comand to predefine some scaling factors for Sway and cycle them. I generally don’t have problems with small letters, so I don’t use scaling, but sometimes my eyes are to tired to bear them any longer. Usage example: i3a-scale-cycle -f 1,1.25,1.5 --next
