Oracle Database by Ciro Santilli 37 Updated 2025-07-16

Here we list public domain academic papers. They must be public domain in the country of origin, not just the US, which had generally less stringent timings with the 95 year after publication rule rather than life + 70, which often ends up being publication + 110/120. Once these are reached, they may be upload to Wikimedia Commons!
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!

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.
