Type Inheritance & Relational Theory: Subtypes, Supertypes, and Substitutability by C. J. Date really nails down type inheritance, and shows how almost all OOPLs have it wrong. e.g., the "diamond problem" isn't an actual problem, just bad implementation.
The Shlaer-Mellor Commons needs to address this in the Shlaer-Mellor generalization rules. Finally, something juicy to work on!

Tomorrow I’m walking off the job with hundreds of my Washington Post colleagues because the company is breaking the law and bargaining in bad faith. Respect our picket line during our 24-hour strike by avoiding Washington Post journalism on Dec. 7, and send a letter to our bosses here: bit.ly/postguildsupport

ORG warns "Clause 2 could allow for the commercial exploitation of personal data under the guise of scientific research. By overextending the definition of scientific research, the clause risks undermining public trust in legitimate research activities."

The #DataGrabBill will “reduce transparency... such as by exempting researchers from providing information to large numbers of individuals or when personal data have been collected a long time ago.”

If you use a Windows or Linux device, it's vulnerable to a new post-exploit attack that can remotely install an undetectable backdoor at the UEFI level. Updates from just about every vendor available today. Impressive work from @matrosov and the rest of Binarly.

3D Print with Purism.

Purism makes products that put you, the customer, in control. Generally, Librem devices are easy to disassemble for access to their internals. For the Librem 11, our focus in the first iteration is on the interior components rather than the chassis itself, which means it has an adhesive back.

If you or a friend have a 3D printer, it’s possible to replace that single adhesive component with a modular back cover and screws.

This year, i didn't wish for any birthday presents. Instead i asked the people to donate to projects that i care about. Since there are so many, i started with two this year: #PostmarketOS & #CodeBerg.

Maybe - if you are priviliged like me and not in need of material presents - you can consider this as well.

#WorkerCoops

"Eleven of the employees stepped up to become worker-owners, with another 13 remaining as employees. An employee can become a worker-owner after working for the bakery for a year and investing $2500 in the business, either up front or through paycheck deductions. Since the bakery opened as a cooperative a little over a year ago, it now has 13 worker-owners and 12 employees."
