old ikea lamp books 14.02.2024

Here are some (most) of the books that I've read, ordered by reading date.
Electronics books and mangas are excluded from the list, I have too many of them to list and I don't remember when I first read them.
I've written the English titles when available.

childhood:
- Microsoft Windows 95, 1998 New Edition, Warren Bates
- Building a PC for Dummies, Mark L. Chambers
- UNIX for Dummies, 4th edition, John R. Levine, Margaret Levine Young
- Linux for Dummies, 4th edition, Dee-Ann LeBlanc
- MS-DOS 5 utile, Daniel Rougé
adulthood:
- The Lord of the Rings, J.R.R. Tolkien (vol. 1 only)
- Introduction à Ada, Pierre Le Beux, Second Edition
- Sword Art Online, Reki Kawahara (vol. 5 and 6 only)
- The C Programming Language, Brian Kernighan, Dennis Ritchie
- Haruhi Suzumiya, Nagaru Tanigawa (12/12 vol.)
- Curiosities of Lotus Asia, Jun'ya Ōta "ZUN"
- Shakugan No Shana, Yashichiro Takahashi (1/22 vol.)
- Kino's Journey, Keiichi Sigsawa (16/23 vol.)
- Higehiro, Shimesaba (2/5 vol.)
currently on the reading stack:
- Structure and Interpretation of Computer Programs, Second Edition, Harold Abelson, Gerald Jay Sussman, Julie Sussman
- The Apothecary Diaries vol. 1, Natsu Hyūga

Some notes:
All of my computer science books came from thrift stores.
Availability of light novels in a language other that Japanese can be abysmal. Kino and Shana only have the firsts volumes officialy translated in English, have long been out of print, and will probably ever be.

webpage logo, i guess this website 17.02.2023

I had this really dumb idea of creating a webpage that would be contained in only one file. Here are some random thoughts and obstacles I ran through while doing this:

This will absolutely backfire one day.

There is no menu to design.

Images. They are encoded in base64, and I had to make compromises on quality to keep the file sizes small and thus the html file somewhat readable:

-Mostly JPEGs in low quality (favicon for example is so small PNG is more efficient)
-Monochrome images
-Smallest resolution acceptable

exampleHere is a 4KB JPEG example.
One compromise I didn't make was to use arhitmetic-coded JPEGs. stb-image.h and old browsers hates them, and the size loss wasn't that interesting.
As a side-effect, this webpage lacks colour. Except links.
