Prove Apple wrong about data recovery and get banned

dag says...

Comment hidden because you are ignoring dag. (show it anyway)

As some of you may know I'm an Apple Fanboy so take this with a grain of salt.

-- was she advertising her services on the Apple Support forums? I can see where that would get you banned.
-- the responses she received on the forum were from other users - not official statements
-- for several years now data on iPhones has been encrypted with the secure enclave. Even Apple can't unencrypt. Depending on the type of damage, it could be very difficult and sometimes impossible to retrieve the data.

With those bits out of the way - I do support right to repair, and I don't like Apple's stance on this type of stuff. I recognise that Apple isn't the company I loved from the 80s - but I still enjoy their products.

Plane Ran Out of Fuel at 41,000 Feet. Here's What Happened.

CrushBug says...

OK, hold the fucking phone here. This video is just a disaster. It is flippant and glossing over the facts of what actually happened. This story is a favorite of mine, so I have done a lot a reading on it.

This happened in 1983 (36 years ago).

>> Do planes seriously not have a fuel gauge?

There is specifically a digital fuel gauge processor on that plane, and it was malfunctioning. There was an inductor coil that wasn't properly soldered onto the circuit board. At that time, planes were allowed to fly without a functioning digital fuel gauge as long as there was a manual check of the fuel in tanks and the computer was told the starting fuel.

The problem is that fuel trucks pump by volume and planes measure fuel by weight. The fueling truck converted the volume to kilograms and then converted to pounds. He should not have used both. In 1983 ground crews were used to converting volume to pounds. The 767 was the first plane in Air Canada's fleet to have metric fuel gauges.

The line in the video "the flight crew approved of the fuel without noticing the error" glosses over how it is actually done. The pilot was passed a form that contained the numbers and calculations from the ground crew that stated that 22,300 kg of fuel was loaded on the plane. The math was wrong, but unless the pilots re-did the numbers by hand, there wouldn't be anything to jump out at them. He accepted the form and punched those numbers in to the computer.

The 767 was one of the first planes to eliminate the Flight Engineer position and replace it with a computer. There was no clear owner as to who does the fuel calc in this situation. In this case, it fell to the ground crew.

>> I would hope there is a nit more of a warning system than the engines shutting off.

If there was a functional digital fuel gauge, it would have showed them missing half their fuel from the start, and the error would have been caught. Because there wasn't, the computer was calculating and displaying the amount of fuel based on an incorrect start value.

That is another problem with this video. It states that "they didn't even think about it until ... and an alarm went off signalling that their left engine had quit working."

Fuck you, narrator asshole.

In this case, low fuel pump pressure warnings were firing off before the engines shut down. They were investigating why they would be getting these low pressure warnings when their calculated fuel values (based on the original error) showed that they had enough fuel.

>> I can't believe the pilot's were given an award for causing an avoidable accident.

The pilots did not cause it. They followed all the proper procedures applicable at that time, 1983. It was only due to their skill and quick thinking that the pilots landed the plane without any serious injuries to passengers.

They ran simulations in Vancouver of this exact fuel and flight situation and all the crews that ran this simulation crashed their planes.

"Bad math can kill you." Flippant, correct, but still not quite applicable to this situation. Air Canada did not provide any conversion training for dealing with kilograms and the 767. Not the ground crew, nor the pilots, were trained how to handle it. They were expected to "figure it out". That, and the elimination of the Flight Engineer position, set these situations up for disaster.

Hypersonic Missile Nonproliferation

Mordhaus says...

The simple point is that as soon as we realized the capability of the Zero we easily and quickly designed a plane(s) capable of combating it.

The Yak-3 didn't enter the war until 1944, at which point the war had massively turned in Western Theatre. For the bulk of the conflict, they were using the Yak-1.

The Mig 25 and Mig 31 are both interceptors, they are designed to fire from distance and evade. The Su 35 is designed for Air Superiority. We have held the edge in our capabilities for years compared to them.

Every expert I know of is skeptical of China's claimed Railgun weapon. As to why they would bother mounting it and making claims, why not? It is brinkmanship, making us think they have more capabilities than they do.

The laser rifle is a crowd deterrent weapon. It would serve almost no purpose in infantry combat because it cannot kill. Yes, it can burn things and cause pain, but that is all. Again, this was claimed to be far more effective than experts think during our diplomatic arguments over China's use of blinding lasers on aircraft. We have no hard evidence of it's capability.

Yes, Russia could sell such a missile to our enemies versus using it directly against us. The problem is that as soon as they do so, the genie is out of the bottle. It will be reverse engineered quickly and could be USED AGAINST THEM. No country gives or sells away it's absolute top level weaponry except to it's most trusted allies. Allies which, for all intents and purposes, know that using such a weapon against another nation state risks full out retaliation against not only them but the country that sold it to them.

Our carriers are excellent mobile platforms, but they are not our only way of mounting air strikes. If we were somehow in a conventional war situation, we could easily fly over and base our aircraft in allied countries for combat. Most of our nuclear capable aircraft are not carrier launched anyway. Even if somehow all of our carriers were taken out and somehow our SAC bombers were destroyed as well, we would still have more than enough land launched and submarine launched nuclear warheads to easily blanket our enemies.

My points remain:

1. It is in the greatest interest of our enemies to boast about weapon capabilities even if they are not effective yet.

2. Most well regarded experts consider many of these weapons to either be still in the research stage, early production stage (IE not available for years), or they are wildly over hyped.

3. There is no logical reason for our enemies to use these weapons or proliferate them to their closest allies unless the weapons can prevent a nuclear response. Merely mentioning a weapon that would have such a capability creates a situation that could lead to nuclear war, like SDI did. I don't know if you recall, but I do clearly, how massively freaked out the Soviets got over our SDI claims. For two years they started threatening nuclear war as being inevitable if we continued on the path we were, all the while aggressively trying to destabilize our relations with our allies. 1983 to 1985 was pretty fucking tense, not Cuban missile crisis level maybe, but damn scary. Putin has acted similarly over our attempts to set up a missile barrier in former satellite states of Russia, although we still haven't got to the SHTF level of the early 80's.

The Zero's Chinese performance was ignored by the U.S. command prior to pearl harbor, dismissed as exaggeration. That's actually the crux of my point.

Exceptional moments do not change the rule.
Yes on occasion a wildcat would get swiss cheesed and not go down, but 99% of the time when swiss cheesed they went down.
Yes, there were wildcat aces that did fairly well (and Zero aces that did even better), but 99% of wildcat pilots were just trying to not get mauled.

Hellcat didn't enter combat till mid 1943, and it is the correction to the mistake. The F6F should have been the front line fighter at the start of the war... and could have been made sooner had Japanese tech not been ignored/dismissed as exaggeration.


Russian quantity as quality? At the start they were shot down at a higher ratio than the manufacturing counter ratio (by a lot). It was a white wash in favor of the Germans.
It took improvements in Russian tech to turn the tide in the air. Lend-lease only constituted about 10% of their air force at the peak. Russia had to improve their own forces, so they did. By the end, planes like the yak3 were par with the best.


The Mig31 is a slower Mig25 with a digital radar. Their version of the F14, not really ahead of the times, par maybe.

F15 is faster than either mig29 or Su27 (roughly Mig31 speed).
F16/F18, at altitude, are moderately slower, but a wash at sea level.

Why would they shoot and run?
We have awacs, we would know they are coming, so the only chance to shoot would be at max range. Max range shots are throw-away shots, they basically won't hit unless the target is unaware, which it won't be unaware because of the RWR. Just a slight turn and the missile can't follow after tens of miles of coasting and losing energy.


Chinese railgun is in sea trials, right now. Not some lab test. It wouldn't be on a ship without first having the gun proven, the mount proven, the fire control proven, stationary testing completed, etc.
2025 is the estimate for fleet wide usage.
Try finding a picture of a U.S. railgun aboard a U.S. ship.


Why would a laser rifle not work, when you can buy crap like this : https://www.youtube.com/watch?v=7baI2Nyi5rI
There's ones made in China, too : https://www.sanwulasers.com/customurl.aspx?type=Product&key=7wblue&shop=
That will light paper on fire ~instantly, and it's just a pitiful hand held laser pointer.
An actual weapon would be orders of magnitude stronger than a handheld toy.
It's an excellent covert operations weapon, silently blinding and starting fires form kilometers away.


Russia does not need to sink a U.S. carrier for no reason.
And the U.S. has no interest in giving Russia proper a need to defend from a U.S. carrier. For the very reasons you mentioned.


What Russia can do is proliferate such a missile, and effectively deprecate the U.S. carrier group as a military unit.

We need carriers to get our air force to wherever we need it to be.
If everyone had these missiles, we would have no way to deliver our air force by naval means.

Russia has land access to Europe, Asia, Africa. They can send planes to anywhere they need to go, from land bases. Russia doesn't /need/ a navy.

Most of the planet does not have a navy worth sinking. It's just us. This is the kind of weapon that disproportionately affects us.

Real Time with Bill Maher: Frank Luntz 7/15/16

Babymech says...

I don't think we can pretend that either of them was trying 100% to engage in serious discussion. Nobody who answers a question with "my whole life has been spent out with the American people, while you're telling jokes" is committed to serious debate, unless the topic of the debate is which countries Frank has lived in.

Still, Luntz was right on one of the few facts they disagreed on - "Reagan's last two Gallup job approval ratings before he left office were 57% in mid-November and 63% in December 1988.

The highest job approval rating of the Reagan administration was 68% -- reached twice, in May 1981 and as previously indicated, in May 1986. As noted, the low point was 35% in January 1983."

Last Week Tonight with John Oliver: Retirement Plans

RedSky says...

Good point. I admit I'm mostly quoting The Economist's recent article on it, since I haven't compared them myself:

"Meanwhile, fees as a percentage of assets under management have dropped from 0.68% in 1983 to 0.12% today (see chart). This compares with an industry average of 0.61% (or 0.77%, when excluding Vanguard itself). Fees on its passive products, at 0.08% a year, are less than half the average for the industry of 0.18%. Its actively managed products are even more keenly priced, at 0.17% compared with an average of 0.78%."

Totally agree with you on diversifying across index funds (as safe as fund managers are in theory compared to other financial institutions, I would never assume any financial company is 'safe') and of course staying under $250K FDIC insurance level.

heropsycho said:

In fairness, Vanguard funds are not almost always the lowest. I'd say they often are, but Fidelity beats them enough of the time that it's close between them.

With that said, I am in agreement with you that I would prefer Vanguard because of their ownership model. But as I accrue assets in my IRA's, I may open IRAs with Fidelity as well, as each of your retirement accounts' balances are ensured per account for up to $250,000. I would trust Fidelity as well, so I might diversify my index funds between fidelity and Vanguard for the insurance and other reasons.

I miss my Commodore VIC-20. Got it in 1983 and learned how to program in BASIC with 3.5 kb of RAM. Backed up programs onto cassettes. Spent many hours playing Radar RatRace.
