Comment Seriously inflated statistics (Score 1, Insightful) 98

"Nationally, students spend an average of $1,200 a year on textbooks" - this claim is extremely difficult to believe. Given the 'ready' availability of most common textbooks as PDFs or ePubs via the internet, and even their solutions manuals, where are all these honest fools spending over $1000/yr on textbooks? There's certainly not seen in classrooms.

Submission + - First victim of SHA-1 collisions: Subversion. Technique was reverse engineered

Artem Tashkinov writes: A WebKit developer who tried to upload "bad" PDF files generated from the first successful SHA-1 attack broke WebKit's SVN repository because Subversion uses SHA-1 hash to differentiate commits. The reason to upload the files was to create a test for checking cache poisoning in WebKit.

Another news story is that based on the theoretical incomplete description of the SHA-1 collision attack published by Google just two days ago, people have managed to recreate the attack in practice and now you can download a python script which can create a new PDF file with the same SHA-1 hashsum using your input PDF. The attack is also implemented as a website which can prepare two PDF files with different JPEG images which will result in the same hash sum.

How can a single AirPod possibly be replaced!? Surely each pair is personally handcrafted and matched by Jony Ive and his elves, each pair with a unique acoustic fingerprint that's as individual as your refined individual personality? To separate a single AirPod from its partner for life is enough of a crime against Humanity, but to flirtively attempt to mate it with another - surely not!

Submission + - SPAM: Satellite Abandoned In 1967 Mysteriously Comes Back Online

schwit1 writes: An American satellite abandoned in 1967 suddenly came back online and began transmitting again for the first time in 50 years.

Amateur astronomers first suspected that they’d found the satellite in 2013, but needed years to confirm that it was still occasionally transmitting. The satellite, dubbed LES1, was built by the Massachusetts Institute of Technology (MIT) and launched into space in 1965.

A mistake in the satellite’s circuitry caused it to never leave its circular orbit, and it eventually stop transmitting in 1967. The satellite’s signal now fluctuates widely in strength, meaning that it’s likely only transmitting when its solar panels are in direct sunlight. Scientists expect that the satellite’s onboard batteries have disintegrated.
