I now prefer almost exclusively digital books, but occasionally, they are available only in paper. The following two are my latest physical purchases:

Something old
The item on the left is the first development book I read, "80X86 Assembly Language", from 1995, which only exists in Spanish. A great book to learn Assembly, but also one that I needed to read two or three times as a teenager to properly understand.
I got nostalgic and decided to search for a second hand copy, as I donated mine long ago to the university where I studied. I don't know if I'll read it again in the short term, but nowadays it is easy to develop for MS-DOS thanks to DOSBOX, and going so low-level is not something you do any more. Or I might do another round of Z80/GameBoy development.
Something new
I'm a firm believer that Go is the best language for building CLI tools, and I can summarize why in these few words: cross-compilation and no execution runtime. I've migrated most of my local shell scripts, and added dozens of useful new commands to an internal CLI tool that I now use daily. Plus, being based on a few simple and clean design patterns, now I am delegating any remaining shell script migrations to AI tools, as they generate a perfect conversion.
In any case, I heard about the second book, >CLI, in a podcast episode, and it sounded very appealing to me. As the examples are already in Go, I'll directly see the book patterns correctly built in this fantastic language, and can probably incorporate a few ones into my tool.
