In 2016 Ciro made a script downloaded Facebook profile pictures.

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 fbdata.torrent of about 2.8GB, mostly compressed. Doing:on Ubuntu 20.04 gives:This dump widely reported e.g. on Hacker News at: news.ycombinator.com/item?id=1554558.

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.

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.

But now that Facebook finally fixed it, it's fine, no need for the video anymore.

The definition of the "dot product" of a general space varies quite a lot with different contexts.

Most definitions tend to be bilinear forms.

We use the unqualified generally refers to the dot product of Real coordinate spaces, which is a positive definite symmetric bilinear form. Other important examples include:The rest of this section is about the ${\mathbb{R}}^n$ case.

The positive definite part of the definition likely comes in because we are so familiar with metric spaces, which requires a positive norm in the norm induced by an inner product.

The default Euclidean space definition, we use the matrix representation of a symmetric bilinear form as the identity matrix, e.g. in ${\mathbb{R}}^3$:so that:

The approach many courses take to physics, specially "modern Physics" is really bad, this is how it should be taught:

This is likely because at some point, experiments get more and more complicated, and so people are tempted to say "this is the truth" instead of "this is why we think this is the truth", which is much harder.

But we can't be lazy, there is no replacement to the why.

I also believe in publishing null results, so here goes.

Thick cardboard paper and Gorilla Tape: the intense Sun heat made the cardboard bend, and even the Gorilla tape could not hold it, leading to light leakage. Even worse, it started to smell a bit, and I got afraid that it could catch fire, so don't do this! Maybe I will try coating with aluminium foil next time, but I'm afraid it might stick to the glass. In any case, even if those setups work, your room may be permanently very dark depending on how far the window opens, which can lead to other problems such as mold. Another downside of this method is that the tape is extremely sticky, and especially difficult to remove if it touches the glass, where you can't use metallic items to scrape it off without scratching the glass. I had to get a solvent and use a lot of elbow grease to get rid of it.

I have tried a few sleeping masks, but none of them were enough on their own. There is always some light leakage around the nose, especially as you turn around in the night. And some of them are too hot. I have tried:

I also considered getting one of those "Perfect Fit Blinds" www.blindsdirect.co.uk/perfect-fit-roller-blinds (archive) which fit between the glass and the insulation. This looks like it could work. But I didn't go for it in the end because my window has 3 glass panels, so I would have to get three of those blinds separately.
