So, I should clarify something: A visual approach is pretty simple from the controller's point of view; it's more work for the pilot. But, the pilot is always the one in command of the plane: If the pilot is unwilling to accept a particular approach, they just need to say so. It may lead to delays, but controllers will accommodate.

I originally said that the pilot had been assigned a visual approach to runway 28 Right. Looking at the charts for SFO[1], and the FlightAware trace[2], I have an alternative: The pilot may have been flying the LDA PRM runway 28 Right approach[3].

(You should open up [3] to look at while reading the rest of this comment.)

As has been mentioned, SFO is a bit weird: The two main runways are close enough together that it's not possible for you to have normal simultaneous approaches. For example, have a look at the diagram for Cincinnati/Northern Kentucky International (CVG)[7], another Class B field. Now, compare that to SFO[8]. At CVG, the parallel runways are far-enough apart that simultaneous approaches are possible, but with SFO, that's not possible. So, the FAA came up with the PRM (perimeter) approach.

Essentially, the plane approaching runway 28 Left is on an ILS approach. The plane on approach to Runway 28 Right is on an approach that is kindof like an ILS approach, but the plane isn't heading towards the runway, the plane is heading to a point to the right of the runway. Notice on [3], the point labelled "CFFKC". That's a fix (a point in lateral space), marking the point that you're being guided to. Note how the fix doesn't line up with the runway; that's why this approach is an "LDA (Localizer-type Directional Aid) with Glideslope" approach.

As per the detailed instructions (in [4], and point 4 in [6]), pilots on the LDA PRM runway 28 Right approach switch to a visual approach after the DARNE waypoint (3.4 nautical miles from the runway end). For most of the approach, they are monitoring a second frequency, which is only used if planes get too close together. But, once you pass DARNE, you no longer need to listen on that frequency. And although tower might have a radar view of surrounding traffic, it's not their primary tool (their eyes are).

If the Air Canada pilot was flying the LDA PRM RWY 28R approach, I think the final sidestep (from the LDA to the runway) may have been missed, or not completely executed, causing the pilot to line up with what he thought was the runway, but what was actually the taxiway.

I'm kinda surprised manufactures don't have full HUDs in commercial airliners yet. For airports that support ILS, it seems like using it should be mandatory, with a HUD providing a visual guide to ensure the pilot is lined up with the correct runway.

I mean sure, you could still have mistakes (pilot types in the wrong runway in a parallel runway airport and lands on the wrong one), but it'd be another check/safety system in place.
That's true but almost all the draw of Linux for developers is the non-graphical tools. GUI software for Windows tends to be much better, especially for stuff that you'd need acceleration for.
To be fair though, Interstellar has really awful sound production. You cannot blame the theatre for that movie. Many theatres actually had signs up explicitly saying that the ear-shatteringly loud music drowning out the dialogue is they way the movie was produced, so don't blame them.

And what awful music it was. Just a terrible, terrible soundtrack. They really should not have let Hans Zimmer play with his organ.

>So to fill in what comes after the ellipses for the typical respondent of news of a laptop running OpenBSD: "Really?

These problems seem related to the choice of WindowMaker, not OpenBSD. Choosing a different window manager or desktop environment won't have the same issues.

Like it or not, the GFW helped to created the "most dramatic periods of economic development" in Chinese history.

Back in 2010, when Google chose to exit China, many argued the exact same that China is isolating itself from the outside. Such feeling is understandable from a western point of view, I mean for anyone from a western background there is simply no Internet if google/twitter/fb etc. are all unavailable. However, a bold however, 7 years after Google's exit from China, it has been proved again and again that the biggest motivation of GFW is the protectionism aiming to help domestic Internet companies - and that actually paid off pretty well.

You don't need Google/fb/twitter etc to have booming Internet/high tech economy. Look at China's social media, online payment, e-commerce, online gaming, AI, shared economy etc, did China miss out. Let me give you a bloody simple number: I didn't use any cash or bank card/credit card in the last 45 days, everything, I mean 100% everything, was paid by mobile.

This is not about some cheap nationalism - it is _all_ about how many good paying jobs can be made available in China for Chinese. It is the exact same as the Making America Great Again crap. Blocking google/fb/twitter was the first essential step to achieve that.

How Spammers, Superstars, and Tech Giants Gamed the Music Industry
Unfortunately we don't have enough information here to know for sure.

For example, the approach controller may have noticed that a plane they recently handed off to Tower was not yet lined up. The controller would then call up to Tower to make Tower aware of the issue.

Or, Tower may have a screen showing them a radar view of the approach, similar to Approach's screen. They may have noticed it there.

But, the nature of aviation radio is such that you use one frequency to transmit and receive. That means you can't speak over anyone else; you have to wait for them to stop talking before you can start. And if you mess up, there's no easy way for you to know (except when someone else on frequency says "blocked").

I find that even with proven non-bleeding-edge hardware with known drivers, battery life and graphics stability are far worse.

In a foggy situation they would've used ILS or even autoland. Looking at instruments instead of out of the window would've prevented this much earlier.
What's missing is, when (relative to radio traffic) did the pilot begin the go-around maneuver. Did they begin doing so before being told to go around, or did they only start to do so after?
As someone who just switched from windows to Mac, when you pick windows you also gain periodic show stopping problems, kafkaesque hoops to jump through randomly in the middle of your workflow, a slightly terrible security architecture and the ability for family and friends to see you using windows and are clearly an expert and then ask you to fix their crapware ridden death boxes. At least you gain thousands of google results for every problem coming your way.

Incidentally yesterday I ran out of disk space on my old windows laptop. There was a windows problem reporting process that ate 100MiB once an hour. Eventually over the space of weeks you lose your entire disk then spend an hour googling the numerous incantations that need to be applied to fix this most of which don't work. Random shit like this happens at least once a week or so and just ruins an afternoon.

Also don't think that the built in ubuntu or windows shell stuff actually works properly. There are many horrible bugs. Nothing on windows works properly for months if not years. Even with creators update, I used putty and virtual box because it was that bad.

Also you're going to miss things like keychain in OSX.

Edit: also my old T440 which I was running windows on, Lenovo couldn't ship working drivers for creators update and the moment that got rolled out TSHTF. This resulted in the SATA controller hanging for 30 seconds every five minutes and locking the machine up. I wasted six hours trying to find a combination of drivers and PM config that actually didn't do this. That's a whole day of work down the pan.

There is just ZERO quality on the platform and I'm done with it.

Wow, that's a lot of detail and analysis. That does make a lot of sense. I know it will be a while for the FAA report to come out, but if it does turn out to be what you've stated, you can totally say you called it.
Tenerife was very different. Here, the aircraft were at the beginning of the runway and clearly visible. In Tenerife, aircraft were at different part of the runway and couldn't see each other until it was too late. That's not comparable.

We know from the recording that the pilot saw planes on the taxiway and asked the tower about it. He would've never landed there after the tower confirmed that the runway should be empty.
it is completely different, in the 15th Century, the Haijin policy was used to stop "barbarians" from flooding the country. there is nothing to gain from trading with the rest of the world because the country was ranked No.1 in the world in almost all metrics. today's GFW is to protect a young but fast growing industry - because the overall economy is not that strong.
If you really want to test an OCR tools, try scanning something like an XBox Live membership card. The fonts on those cards seems to be specifically designed to mess with OCR.
Then this specific type of incident would likely not have happened.

The pilot here was flying visually (which I expect either means a visual approach, or else the LDA PRM Runway 28 Right approach).

If the airport was fogged out, the pilot would be on an ILS or RNAV (area navigation) approach. The former uses ground-based signals to provide precise lateral and vertical navigation; the latter uses either GPS or multiple ground-based aids to accomplish the same thing.

The downside to ILS, RNAV, etc., is that you can't fit planes as close together while still being safe. That's why you get delays when major airports have reduced visibility: The flight scheduled are "tuned" for maximum planes per runway per minute, which is only possible when skies are clear and winds are (relatively) calm, so that you can use visual approaches.
Is there any reason medium has outsourced it's embedding UX? It's one of their key integrations/differentiation UX wise.
I would assume it was edited. He only joins the frequency about 30 seconds before it happens. That means tower only took control once he was 60 seconds before landing. I don't know the procedures at SFO but that seems too short.
Describing Apple's situation as its "vision" or "strategy" is misleading. Apple required significant prodding to get to the point described in the article. A public company without a dual ​voting ​structure can only resist shareholders so much. ​It's hard to imagine that if Apple were incorporated today that the founders wouldn't have wanted to retain significant control. ​In any case, even with a dual structure, founders owe fiduciary duties to other shareholders​; they ​can't do whatever they want.

Also, these are not ​"​alternative models of capitalism​". These are alternative models of public company corporate finance - a much narrower discussion.
100 miles a week will tax the bio-mechanics of most people in the first world. Granted doing those 100 miles at 10 min/mile is far, far easier than doing it at 6:00 to 7:00 pace. And doing lots of LSD (long slow distance) DOES have proven physiological effects.

But please don't treat 100 mile weeks as some trivial task. I have been running for > 25 years and have run from a 4:40 mile to a 2:44 marathon and 1:15 half and my max week was 84. I was doing consistent 70 mile weeks in college for a while and finally couldn't continue due to injury.

I do agree with your core point that most people have no idea what their true limits are. I have seen friends who hated to lose pass out at the finish line of a race. I find I don't even improve until I hit about 40 miles a week with at least one LT run of 4 to 6 miles and a >= 13 mile long run. That only takes about 4 to 5 hours a week (not including extra showers, drives to runs, necessary strength work, etc.) I guarantee most spend far more than that on Netflix et al.

P.S. Congrats on your race!
If the pilot initiates a go around they need to announce it to the ATC. It is usually a drastic full power pull up that will certainly disrupt nearby air traffic.

So the pilot probably did not start the go around before being told so.
I guess the part I'm missing is why you care whether the goofy selfie disappears.
If I was going to explain a bloom filter like you're 5... a bloom filter is like a savant who never forgets a face -- maybe he's got a job in passport control in Arstotzka -- if you show him someone's face or picture once, he'll never forget it: if any time later you show him the same picture and ask him "have you seen this face before?" he'll say "yes" without fail. If he replies "no way", you can be 100% sure he's never seen it. But his memory isn't photographic: he confuses people's faces after a while, recognizing faces he's never seen, and that becomes worse the more people he's seen. So to be safe he doesn't reply just "yes" but "hmm, I guess so".

In computing terms the interface has 2 methods:

- takeALookAtThisFace(x)

- yaSeenThisFaceBefore?(x) which returns either "no way" or "hmm, I guess so".

"no way" means P(x is a member) = 0. Its negation is not "hell yes" (P(x is a member) = 1), it's "maybe" (P(x is a member) > 0).
> A woman who has a start-up she's trying to raise money for is a WHORE if she puts up with unwanted sexual advances from investors?

She is saying that if you put up with this kind of behavior rather than cutting it off, you are part of the problem.

To be fair, this goes for men, too. I have had the "joy" of turning down funding because the person involved was such a jackass. Fortunately, he wasn't offering a huge sum of money.

Add another zero, and my partner and I would probably have been in a major argument. And two zeros and I probably would have swallowed my pride. I acknowledge that I can be bought--I just hope my price is high enough to make it worth it.

I really don't envy women in this environment. Lots of people running VC funds really like to throw the power imbalance around even towards men. Adding sexual dynamics to the mix has to be ferociously toxic--think about the abuse of Hooter's waitresses and then dial the restraint to zero.

Again, virtual air traffic controller!

I think many of the readers here would be interested in virtual ATC, as many parts of the brain: Keeping many things in order, looking multiple steps ahead at what's going to happen (it takes time for a plane to turn), and communicating with your "customers".

The only downside is, you shouldn't sign in to control when you're on call 8-)

The moral might also be that automatic guided landing approaches should be mandatory whenever they are available.
I usually cook my own questions that involve a loop and an if statement. I kid you not, plenty of candidates cannot do simple stuff, and they're interviewing for a developer position.

If you don't know how to reverse a string, or split an array of ints into two with even and odd ints, or write a while loop that terminates on a specific word - I have zero belief that you can fill the position I have available.
You're kidding?

Red 'X's on a runway usually denote an inactive or out of service runway.

They ARE actually quite different in terms of lighting, width etc. and 99.9% of the time there is no issue telling them apart. Runways also have extra approach lights etc. at night to really make it clear where you should be pointing the nose.

(NB: Check out the video posted elsewhere in this thread of the cockpit view of a 747 landing at SFO at night. It is pretty clear which is the runway and which is the taxiway).

However, it is those 0.01% of the times where the weather is bad, or you are landing into the sun or the traffic is really congested and you are trying to talk on the radio at the same time etc. where mistakes can be made.

In this particular scenario in the OP, I am assuming that having 4 heavy aircraft lined up on the runway pointing at the landing plane, then 4 sets of bright landing and navigation lights on the taxiway could have looked like runway lighting, and disoriented the Canada Air pilot? Just outside speculation here, but stranger things have happened.

It's like the case of the Air New Zealand CD-10 crash into Mt. Erebus in clear weather. Non pilots were incredulous that a plane could fly into the side of a mountain in clear daylight weather, but the visual trickery played by bright snow on a slope actually fooled ALL pilots on board that they were flying down a valley instead of into an upward slope.

Why can't they make taxiways more obvious (e.g. paint them bright red)? Seems like it would be a small cost for a lot of insurance against an accident.
I'll gladly tell them how the modular arithmetic works, I just want them to fill out the rest. Many are unable to, which tells me that they don't know even the simplest constructs in programming.
If ILS and autoload can prevent this, why is it not mandatory?
Just a very naive question, would not it be possible for the taxiway lights to only be visible from the ground?
