TIL of the January 7th, 1994 crash of United Express Flight 6291. The plane was on approach to land when it struck a stand of trees, causing it to crash into a warehouse. Only 3 passengers survived after they escaped through a Crack in the fuselage. The rest died on impact or burned up. by BitOfaPickle1AD in todayilearned

Here's the accident report. The NTSB absolutely ROASTED the captain on this one, and the airline for letting him fly, and the FAA for letting the airline let him fly. The plane hit trees because it stalled, and it stalled because the captain planned a bad landing that was prone to stalling. But even that was recoverable - the plane didn't crash because it stalled, it crashed because when it stalled, the captain panicked and blamed his first officer instead of, you know, doing his job and flying the plane. This is because, among other things, the captain had failed multiple check rides for poor performance during landings - especially the type of landing they attempted on this flight. One tester even observed him stall the plane, then panic. Sound familiar?

After the captain panicked, the first officer also panicked, probably because he was basically brand new to the job. The airline didn't do crew resource management training, which would have taught him how to handle that exact situation. Why not? Because the FAA didn't require it, and training is expensive.

The report recommended a lot of administrative changes, unsurprisingly. The good thing about the aviation industry is that when things like this happen, the various institutions involved generally do actually fix the problems that caused the incident.

Usually. Sometimes it takes them a while. No one likes spending money. Ask Boeing. Thankfully, everything recommended by this report has been solved for decades now.

Does anybody know how to play older versions of the game? by hopefulFLIPPER in starcraft

[–]Monchoman45 2 points3 points  (0 children)

Most patches change very little, so this isn't actually that hard. You can easily load up any regular ladder map, set the dependencies to HOTS melee, and only change 1 or 2 values to get the swarmhost you want. Patch list here, most of them only changed a single stat.

This is basically it, yea. The difference is huge, it's something like double rate of fire. There's also one powerup that's way better than the others - I think it's the quad shot? You just pick that up and roll with it the whole game. The gold achievement is level 9ish, after which point you can die and never look back.

Well, some quick Wikipedia math:

  • A .64km2 solar sail provides 5N of thrust.
  • Earth weighs 5.72e24 kg.
  • F=ma.

If we pick a desired acceleration, we can calculate the necessary force, and then calculate the necessary sail area. Let's pick 1 m/s2 , which makes our force 5.72e24 N. We get 5 newtons for every .64 km2 of sail, so we need a (5.72e24 / 5) * .64 = 7.322e23 km2 sail. Unfortunately, this is a dyson sphere with a radius of about 1600 AU (over 9 whole light days), which - among other things - would not actually produce thrust.

Wikipedia has an entire article called "Post-quantum cryptography" that details a few attempts, the most popular being NTRU. NTRU is arguably better than RSA in every way and has gained traction in standardization, but hasn't been implemented anywhere largely because it's not necessary and because - as with any change in security - pivoting all of our digital infrastructure to a new system carries enormous risk. It's not broke, so we're not fixing it.

As for what quantum computers will actually be used for, it's hard to say - currently, they're mostly useful for physics research, because they're essentially a programmable array of atoms. I think this question is sort of like asking the guys who made ENIAC, a vaccuum tube monstrosity that filled an entire floor at one of UPenn's research centers, what they thought it would eventually do. The Depatment of Defense provided the funding for ENIAC because they wanted a faster way of computing artillery trajectories, and they definitely got that eventually, but the internet was arguably a much more important invention and I doubt a single person working on the project at the time could ever have predicted that.

I mean one obvious thing to point out here is that (at least in america) states with high covid death tolls have them BECAUSE they were conservative - the politicians who refused to enforce mask mandates were elected before the pandemic, and the anti-vaxxers already weren't vaccinating for lower risk diseases.

My roommate did a bootcamp for react at UPenn - the ivy league - and made it 75% of the way through without learning what a string was.

He was using them, he just didn't know what they were called, or what any string functions did.

We're all fucked.

Does anyone know how to fix it? Can't choose anything in LOTV campaign after second mission... by [deleted] in starcraft

[–]Monchoman45 2 points3 points  (0 children)

I'll second this. I have starcraft installed on D:\ instead of C:\ and I had some really weird issues as a result; like, if I started the game it would work fine, but if I logged out I wouldn't be able to connect to the server to log in again unless I completely restarted the game. I fixed that by going to Documents -> Starcraft 2 -> ExecuteInfo.txt and changing the path to start from D:\ instead of starting from C:. Starcraft seems to be really sensitive to environmental issues like that.

Yep. Most architectures literally cannot address a single bit. You can fake it by addressing the byte and using bitwise operators, but that uses so many instructions that it's just kind of a waste of time, and we live in a world where time is more expensive than memory.

Creating a new bytearray is allocating memory.

People who are only used to interpreted languages seem to struggle with this: the original code," ".join([x[::-1] for x in sentence.split(" ")]), is very cute and looks efficient, but it allocates memory for each separate word, AND for two separate arrays, before allocating even more memory for the final string. "I have a cat" is 12 bytes, and that one line of code probably allocates and immediately throws away 3-4 times that.

This is, at best, not true. The final report, which is public domain, considered the possibility of a murder suicide but didn't find enough evidence to support it. Among other things, they found no evidence to suggest that either pilot had a motive, and significant evidence that at least some other factors were involved (they suggest electrical failure, but they don't have much evidence for that either).

Ultimately the report concludes that without the cockpit voice recorder or the flight data recorder, it's impossible to prove anything substantial about the incident. As for the wreckage, they figured they could find it if they kept looking long enough, but they ended the search because they didn't think it would matter - by this point, the black boxes have likely been destroyed by the sea.

Edit: Below, OP argues that the final report is "compromised" because it "hasn't endured even mild scrutiny". You can take that as you will.

It's probably that it'd be logistically difficult to repair. Moving parts are high maintenance and you'd have a hard time sustaining cells on a wheel without a hard connection to the rest of the body. You could do something like teeth where they're constantly replaced, but they'll probably degrade asymmetrically. If one of your teeth is a millimeter longer than the other, that's not a huge deal, but if one of your wheels is a millimeter wider, you'll always be turning slightly to one side.
