Ciro Santilli has enjoyed doing projects dealing with with lots of data! They usually have a large overlap with Ciro Santilli's naughty projects, but not always!

This mini-project walks the category hierarchy Wikipedia dumps and dumps them in various simple formats, HTML being the most interesting!

Buying October 2023 as an immediate backup phone after the Google Pixel 3a (2020) touchscreen died, and Motorola Moto G6 Play (2018) wouldn't connect to giffgaff.
Still working checks: May 2024.
Circa 2020, a bowl fell on it from about 25 cm height and broke the screen. £159.99.
2023-10: unable to connect to Giffgaff. "Network unavailable". Same SIM works in other phones. So annoying. Update APN to match: www.giffgaff.com/help/articles/internet-apn-settings-guide. Went next to a tower and then got signal. So the receiver is much worse than the pixel one. Vibration appears to be broken.
Authy sync worked: 2023.
December 2023: found the keys for the Kryptonite Kryptolock and the Abus in the house, so now I've got backup!
2023 lost one of the two keys to Kryptonite Kryptolock and to the Abus padlock:
2018 Kryptonite Kryptolock. Looks like: www.kryptonitelock.com/en/products/product-information/current-key/002031.html Includes Transit Flexframe-U Bracket carrier
2017 Abus Sinus Plus 471/150 HB U-lock. Sample seller with image: www.lockshopdirect.co.uk/products/abus-sinus-plus-471-d-lock-230mm-shackle-62620/
2017 an Abus chain and padlock, can't see marking easily. Chain length: 82cm.
During the early 2020s, many of the idiotic social media platforms started adding a non optional "feature" of suggesting feed posts by people you don't follow:
It must have been some A/B testing overload that made that decision to try and make things more addictive for everyone. Or perhaps as a way to drive revenue with people paying to cheat the algorithm and boost their posts.
European Union we need you.
Info-ZIP by Ciro Santilli 37 Updated 2025-07-16
The dominant Linux implemenation, e.g. default zip command on Ubuntu 23.04.
So dominant that it is usualy called just "zip".
This paper is in the public domain and people have uploaded it e.g. to glorious Wikisource: en.wikisource.org/wiki/On_the_Relative_Motion_of_the_Earth_and_the_Luminiferous_Ether including its amazing illustrations.
