  • Yeah, I don’t think it’s possible for the concept to click until at least learning how to calculate Fourier transforms by hand. Before then all I could say when hearing about orthogonality was “Uh-huh, sure”, but you never really believe it. Only when you have calculated something like “what is the frequency of the delta function?” and seen the answer with your own eyes, not through someone’s interpretation, do you start believing it.







  • The helicopter route at the time of the collision allowed the Black Hawk to fly as close as 75 feet below planes descending to land on runway 33 at Reagan National Airport, according to the NTSB. With allowable errors in the helicopter’s altimeters and other equipment as well as Army rules expecting aviators to hold their altitude within 100 feet, it could end up being much closer.

    “How much tolerance should we have for aviation safety whenever civilian lives are at risk?” asked Todd Inman, NTSB board member. “How much is that tolerance,” he continued. “I think it should be zero.”

    Sounds like the tolerances weren’t big enough! Odd interaction putting those two paragraphs next to each other. NTSB demanding zero margin for safety…








  • It’s worse. They are saying that the EU copyright law, as written, only allows decompiling/reverse engineering to “fix bugs”. A bug fix would involve a software patch of some sorts. But the security researchers did not have time to write a patch yet, what they did is tell the customer “Yep, it’s fucked. Your vendor put in a killswitch to make the trains brick themselves.” So that does tell them where the problem is, but it is not a bona fide bug fix from the Bugfix region of France, and therefore illegal.


  • he started firing, [Police Commissioner] Tisch said, killing a police officer working a corporate security detail

    “He was doing the job that we asked him to do. He put himself in harm’s way. He made the ultimate sacrifice,” Tisch said.

    Off-duty police officers working as private security are not doing the job we the public asked them to do! During the time they are getting paid, they are protecting corporate interests, not the public in general. Frankly, “corporate security detail” is a corrupt impersonation of a police officer - they wear their official police uniform, they act under the color of law, but they are not serving the police or the public. Fucking Cyberdyne Systems/Omni Corporation privatized police cyberpunk shit. Irks me how this police “impersonator” is getting full honors from the police commissioner, and photos in the AP of police and medical staff standing at attention in respect of the ambulance carrying the body, and meanwhile the other security guard killed who did not daylight as police during their off-the-clock hours doesn’t even get a name mentioned.

    shot a guard at a security desk

    Only their gang members matter to them.


  • Newag [train maker] claims that the Dragon Sector [whitehat hacker] team endangered passengers’ safety by modifying the software without proper experience. But Newag then turns right around and claims that Dragon Sector did not modify the software at all. They point out that EU law only allows reverse engineering of software in order to fix bugs. And if Dragon Sector did not actually modify the software, it cannot have fixed any bugs, in which case their reverse-engineering must be illegal.
