mveety··on American Airlines Accidentally Let Too Many Pilots Take the Holidays Off
Airline passengers don't generally care about it being safer on average. If the autopilot can't make a landing in a 30 kt crosswind all of the time people won't fly on that plane. People have much higher standards for acceptable safety with aircraft than cars. Also, autopilot isn't really designed to replace the pilot. Its designed to reduce workloads during departure and approach and make cruise less shitty. Autopilots are entirely unable to handle even simple failures and even in many cases do simple things like climb at a specific airspeed or do wind drift corrections. Car are just much simpler, have fewer consequences, and have lower expectations of safety. Until we get more versatile autopilots, aircrew acceptance, and/or lower expectations of safety, I don't see self-flying airliners anytime soon.
mveety··on Show HN: Airport Locations from Around the World
Yeah, the US and Canada are fantastic exceptions to the normal rule of making aeronautical information impossible to find and use. It really sucks that GA is so much more rare outside of North America. For all the bitching we do about the FAA, they're a generally pretty good organization that actually wants people to fly. The vibe I get from most other countries' aviation authority is that they just don't want us up there and that we're a pest or threat. They make it expensive and regulate it into the ground, or worse, ban GA altogether. In the US, airspace is, for the most part, open or easy to get clearance to (barring the presidential TFR and DC ADIZ nonsense), getting a license is more or less easily attainable, and buying or renting an aircraft is super easy. This isn't really the case anywhere else in the world.
mveety··on Boeing 757 Testing Shows Airplanes Vulnerable to Hacking, DHS Says
No you need your basic sixpack. The radar altimeter might do but it only tells you your altitude in reference to the height of the stuff under you and most only up to 2500 ft. In terms of survival, I would want at minimum an artificial horizon, airspeed indicator, altimeter, and lots of fuel to hopefully fly to somewhere with better weather.
mveety··on Boeing 757 Testing Shows Airplanes Vulnerable to Hacking, DHS Says
No. You absolutely need instruments. Flying IFR without instruments is an absolutely sure fire way to get killed. You can't fly straight and level without an artificial horizon. You don't know if you're descending without, at the bare minimum, an altimeter. You don't know if you're about to stall without and airspeed indicator. You don't know which direction you're going without a compass. Not having instruments in ideal VFR conditions is perfectly fine, but if the weather goes south you're dead.

Edit: also some aircraft are going totally glass. I've seen some homebuilts and super cubs without steam gauges completely, and it's just a matter of time until Cessna, Boeing, Airbus, etc eliminate them.

mveety··on Let’s write a simple Kernel (2014)
The Plan 9 compilers work exactly like this, every compile is a cross-compile. It's extremely convenient because you can do all of your builds on your really fast machine for all of your other machines or if you're using a slow machine. It's one of the reasons I can live happily with a raspberry pi as one of my main workstations. All you need to do to build for a different target is change $objtype.
mveety··on Most sushi fish isn't fresh
I'm still hesitant to agree that we caused the mammoth extinction. There just weren't enough people at the time to do it with the technology we had, especially in places that lack enough cliffs.
mveety··on Two days in an underwater cave running out of oxygen
I disagree here. You're dangerous until you know you know what you're doing. Having a bad scare might make you not repeat that situation, but you're still just as dumb after it as you were before (well, at least that's been true for me).
mveety··on The Decline of Imgur on Reddit and the Rise of Reddit's Native Image Hosting
Probably "every web service expands to become a social network."
mveety··on Study indicates mushrooms may be the safest recreational drug
True you don't, but they are easier on some level and give you no real escape once you commit to taking them. Sitting down and putting the work in is certainly as effective, but you can bail on committing to that where as there is no escape from the chemicals once they're in you.
mveety··on Nearly 1 in 3 drugs have a significant safety issue after FDA approval
That depends. AFAIK, if its prescribed to you and you give it to someone else, that's illegal whether or not its scheduled. Otherwise, if it isn't scheduled, there's no real legal issue there.

Drug testing in the US is insane.

mveety··on How the Bantu people surged across two-thirds of Africa
Things like that come from "cultural contact" which can be peaceful or violent.
mveety··on Saudi king orders that women no longer need man’s permission to travel or study
> Rape victims arn't punished in Saudi Arabia. Theres no crime of being raped.

True, but they did commit adultery when they were raped. Technically, they aren't punished for being raped, but in reality, they are punished for being raped.

mveety··on Bilingual speakers experience time differently, study finds
You can do it in swedish in a similar way, so I would think this is possible, too, in norwegian (the languages are really quite similar).
mveety··on White House Indicates Potential Crackdown on Recreational Marijuana
Fentanyl is a thing also because it's easier to make than heroin because the reactants needed are easier to get your hands on, therefore cheaper for the dealer's/cartel's/gang's chemists to make.

On the more potent point, almost(?) all of the more potent opioids are derivatives of fentanyl and iirc use fentanyl in the synthesis so probably won't become a street drug. Also they're so potent they really are only good for killing people. (Honestly I'm suprised fentanyl is a thing because the active dose is like tens of micrograms and requires expensive equipment to measure safely. But I doubt drug cartels care if they're customers are poisoned by their product.)

mveety··on Circuit building: stop using antique parts (2014)
Well tube amps do actually need to warm up, but people think it takes minutes to hours for them to warm up when it really takes like 2 to 5 seconds. That, I think, comes from a lack of knowledge about how tubes work and the general cargo cult surrounding sound electronics.
mveety··on PDP-10/its: Incompatible Timesharing System
Actually it's not as bad as it looks at first glance. At least on OpenVMS, you normally use it like sed, and its not much worse than writing some regex, normally.

Granted, writing a text editor in regex sounds awful.

mveety··on APFS is coming soon: iOS 10.3 will automatically upgrade your filesystem
APFS can't provide the stability that ZFS does because it hasn't been beaten on for long enough yet. I have a hard time trusting a new filesystem to store anything remotely important until its been beaten on long enough to find many of the nasty pathologies. Features don't matter as much as stability. Keeping your data safe is the #1 thing a filesystem needs to do.

Also, based on how the quality of the OS has been in the last few versions, I'm not sure I entirely want to trust brand new software from apple right now. In my opinion, they don't take bugs seriously enough, and a filesystem is a hell of a lot more complicated and important than a music player, web browser, or email client.

mveety··on APFS is coming soon: iOS 10.3 will automatically upgrade your filesystem
Yes, bit rot happens all the time. Normally the drive its self catches and repairs these errors, but sometimes they slip through and become the filesystems problem. It doesn't really happen super often, but the fact that it happens at all mandates that filesystems that care about data integrity handle it.

mveety··on CDC considers lowering threshold level for lead exposure
That and the higher efficiency of diesels (assuming you're talking about little planes). Still it's a really long road ahead. For GA aircraft I think a better solution right now is a drop in replacement for 100LL (which is getting worked on) or getting leased engines certified for mogas or modified to run on it.
mveety··on FreeBSD on a MacBook Pro
A shell is a shell for the most part. The details can be a bit different (like your $PATH), but otherwise its largely the same.
mveety··on FreeBSD on a MacBook Pro
If its for the broadcom cards that's probably still a negative. I was running 11-CURRENT up until the release freeze and it never started working. That being said, it wouldn't surprise me if Adrian has it working by now.
mveety··on Microsoft planning to enable x86 on ARM64 emulation in Windows 10 by Fall 2017
Yeah, thats correct. The some (most?) of the first series (merced) of itaniums had hardware to help accelerate the emulation of x86 instructions. I don't know about the later iterations of it though as I've only run OpenVMS on the later ones and not Windows.
mveety··on Wazer introduces the first desktop water-jet cutter
I heard stories about injuries you can get from high pressure leaks from hydraulics guys. By all accounts they absolutely horrifying. They would have their flesh detached from their bones and oil basically soaking into their flesh so that it becomes necrotic later on. Plus they're said not to hurt immediately, doesn't help with treatment. Makes me glad I don't work on hydraulics that's for sure.
mveety··on Wazer introduces the first desktop water-jet cutter
You can basically use any old sand as long as it's meshed within spec for your machine depending on what you're cutting.
mveety··on Wazer introduces the first desktop water-jet cutter
With garnet, you can recycle it on site and their some companies that will buy and recycle your abrasive to resell. That being said, garnet sand is cheap as shit and it's more expensive for most shops to recycle. I've heard that factories making backhoes and the like cutting lots of like 1/4 inch plate will because they're using just so much that it makes sense to recycle on site. All that being said, the sand will go round and be a less effective abrasive after a few uses.
mveety··on Mysterious 'ping' sound from sea floor baffles Igloolik
I'm not a climate change denialist, but I am a climate change optimist. I think it would be possible to cap things off at two degrees, but we would have to start sucking CO2 out of the atmosphere and doing something with it (like big tanks or put it underground as dry ice, etc). Anyone that thinks we can stop this by producing less CO2 is deluded. We're well beyond the "unmitigated disaster for our current environment" ppm level. If we can't fix this, at least life will evolve and move on after we and many other species go extinct due to human activity.
mveety··on 25 Years After Junk Science Conviction, Texas Admits Sonia Cacy's Innocence
But then prosecutors would be much less willing to take acceptable risk when called for because the punishments are so draconian. That being said, letting a dangerous criminal free is much better than having a single innocent incarcerated.
mveety··on 25 Years After Junk Science Conviction, Texas Admits Sonia Cacy's Innocence
Sovereign immunity is a mixed bag. It protects police, judges, prosecutors, etc from having frivolous or retaliatory lawsuits filed against them by persons with a grudge. On the other hand though, it lessens accountability because someone who has been genuinely wronged by a malicious police officer, judge, prosecutor, etc has no real means to hold the individual accountable for their actions. Sure the departments can be sued, but that does little damage, harms innocents, and doesn't not bring the person accountable to justice. My gut tells me there is some acceptable middle ground here, but I have no idea what it is and I'm not sure anyone really does. I do think, if I only had the two options, that having immunity, while far from perfect, is a better option than the opposite because it protects innocents, which is more important than punishing criminals.
mveety··on Apple just told the world it has no idea who the Mac is for
Yes but IIRC most of the userland and many of the libraries are from FreeBSD.
