Facebook profile face dump Updated 2025-07-16
This was possible at the time without any login by using a 2010 profile ID dump from originally announced at: blog.skullsecurity.org/2010/return-of-the-facebook-snatchers since profile picture access was not authenticated.
The profile ID dump was downloadable through a BitTorrent named on Ubuntu 20.04 gives:This dump widely reported e.g. on Hacker News at: news.ycombinator.com/item?id=1554558.

of about 2.8GB, mostly compressed. Doing:find . -type f | xargs sha256sum | sha256sum

At some point however, Facebook finally started to require tokens to view public profile pictures, thus making such further collection impossible, e.g. as of 2021: developers.facebook.com/docs/graph-api/reference/v9.0/user/picture mentions:This is also mentioned e.g. at: stackoverflow.com/questions/11442442/get-user-profile-picture-by-id. This major privacy flaw was therefore finally addressed at some point, making it impossible to reproduce this project.
Querying a User ID (UID) now requires an access token.
Ciro downloaded 10 thousand of those pictures, and did facial extraction with: stackoverflow.com/questions/13211745/detect-face-then-autocrop-pictures/37501314#37501314
He then created single a video by joining 10 thousand of those cropped faces which can be uploaded e.g. to YouTube. Ciro later decided it was better to make those videos private however, as sooner later he'd lose his account for it.
Companies like YouTube blocking this kind of content is the type of thing that makes companies take longer to fix such gaping privacy issues, and is a bit like security through obscurity. A video makes it clear to everyone that there is a privacy issue very effectively. But people prefer to hide and look away, and then 99% of people who know nothing about tech get their privacy busted by actual criminals/government spies and never learn about it.

Apple Inc. Updated 2025-07-16
- owns the entire stack and creates high quality highly optimized systems
- creates closed lock-in systems without inter-operability and actively fights users from owning their devices
- do they give back enough to open source, or do they leech mostly?

Applications of Josephson Junctions Updated 2025-07-16
- the basis for the most promising 2019 quantum computing implementation: superconducting quantum computer
- Josephson voltage standard: the most practical/precise Volt standard, which motivated the definition of the ampere in the 2019 redefinition of the SI base units
- SQUID devices, which are:
- very precise magnetometer
- the basis for superconducting quantum computers
Applications of Lie groups to differential equations Updated 2025-07-16
Solving differential equations was apparently Lie's original motivation for developing Lie groups. It is therefore likely one of the most understandable ways to approach it.
It appears that Lie's goal was to understand when can a differential equation have an explicitly written solution, much like Galois theory had done for algebraic equations. Both approaches use symmetry as the key tool.

Seems to work OK. But you're fighting the symptom, and it will eventually come back.
