cornellwright··on Google's latest iPhone rival off to a rocky start
I had some trouble with burn in on an OLED TV that was being left on all the time. I did some research and found out that the effect goes away by leaving the screen off for a few hours every day. I set the TV to turn off every evening, and the burn in problem went away and less electricity was wasted.

I wonder if this is happening from very heavy use or something else that's not allowing the screen to recover.

cornellwright··on Student Debt Giant Navient to Borrowers: You’re on Your Own
However the pizza restaurant also doesn't have anything about helping you make good, long-term financial decisions plastered all over it's website.

If Navient wrote "call us and we'll screw you" then that would be fine as the customer would get what exactly what they were promised.

cornellwright··on Why We Should Adopt Driverless Cars That Kill People
That's fine and that is already an acceptable method so long as you can make the case for why it's representative and do some real world testing to validate it.
cornellwright··on Why We Should Adopt Driverless Cars That Kill People
>> Regulators test new products until they feel certain that people will not be put at risk. Inventions from elevators to aspirin were subject to fierce scrutiny before they were broadly adopted. We can’t apply the same level of scrutiny to driverless cars.

This article is clearly written by someone who has never worked on a safety critical system. There is a method for establishing risk and making risk-benefit tradeoffs, not just feeling certain. If we did that many more people would be killed.

If the author is arguing about public scrutiny, then I generally agree with the argument, but existing safety engineering practices will work for driverless cars.

Source: I work on hardware and software for surgical devices (among other things).

cornellwright··on Libtiff goes offline
Tiff is very useful because it lets you do almost anything. A tiff image is just several arrays of numbers, you decide how many bits, signed, unsigned, float, int, etc.

This is very helpful for processing which treats each pixel as a sample of the scene, such as computational microscopy or remote sensing. I've always wondered if that had something to do with why it was hosted at remotesensing.org.

The most-produced airplane [1] seats 4 people. Only ~43,000 have been produced since the 50s.

cornellwright··on Why Tech Support Is Purposely Unbearable
If you pay for Google Apps they do. I've had to call them a few times, and they were actually fairly helpful, even calling me back the next day to make sure the problem was resolved.

Judging by the number they called me from their call center is in Ireland.

Yes.

Projecting black is currently an open problem in AR right now.

(Though Magic Leap's videos seem to indicate they've solved it. I'm still skeptical though.)

cornellwright··on The Trollable Self-Driving Car
From other articles I've seen this is something that's already been dealt with. One of the problems they had early on was all-way stops where human drivers were so aggressive that the self driving car would never get its turn to go, instead getting skipped by humans that just went when it hesitated for an instant.
cornellwright··on The Trollable Self-Driving Car
It's more than just deterministic, but deterministic and stupid enough to make do some really undesired behavior. Using the same example as before, if I run a full speed toward the street, almost every car is going to screech to a halt. Doing this a rush hour, would be incredibly disruptive and probably cause a small traffic jam if no one made me stop.

The question with self driving cars will be, for example, can a group of people "herd" one into a garage to steal it, or perhaps get it to do something crazy like drive into a lake. My guess is at some point the car will just sit there, just like you would if a huge group of kids were trying to do this to you.

cornellwright··on The Trollable Self-Driving Car
I don't know, a lot of these things seem to have analogs to human drivers.

I can cause emergency braking on the road outside my house by behaving like I'm about to run into the street while never leaving the sidewalk.

I could get on an overpass and shine a bright spotlight in drivers' eyes at night.

I get what the author is saying, and there will be a continual need to improve self driving cars. Sure there may be different ways to troll them, but I don't think he makes a strong case that they will be particularly more troll-able than humans.

cornellwright··on Google says self-driving car hits municipal bus in minor crash
I wouldn't necessarily say cut out attorneys, but provide sane liability limits so that awards don't go much beyond costs actually incurred.

The only exception I'd make to that would be cases of withholding a known defect, like the self driving car equivalent of the Takata exploding airbag fiasco.

cornellwright··on Google says self-driving car hits municipal bus in minor crash
Another way to do it would be for each manufacturer to have to price in liability coverage to their vehicle. This could be done as a yearly or monthly software license fee that the current owner/operator of the vehicle has to pay. It creates the right incentive for manufacturers because they can charge less (or make more money) if their cars are safer and have fewer claims.

We'd probably also need some amount of limits on full tort liability though since the manufactures would be bigger targets for lawyers than individuals.

cornellwright··on Ask HN: What would happen if Apple removed Uber from its App Store?
Does Apple get a cut of Uber fares from in-app purchases? (I think the standard amount is 30%.) If that's the case, the money lost would be one more reason for Apply not to do this, or perhaps a reason to reject the Uber app if Uber refused to pay.
cornellwright··on After the Gold Rush
Oh no you have to do something new to get rich.

There's still plenty of money, talent, and success out there for new, good ideas. It being hard to fund the same old thing again and again is more of a feature than a bug.

And the argument about the last few YC classes - it takes years to see who the stars are. I remember seeing one of the founders of Stripe speak when they were in YC. It wasn't clear they were going anywhere. What they were doing was cool, but there wasn't exactly lots of hype about it. Their success only looks obvious in hindsight.

cornellwright··on Twitter's missing manual
> On one end of the spectrum you have tools like Notepad, where the only easter egg is that pressing F5 inserts the current time.

I wonder how many people reading this just opened Notepad to try this.

cornellwright··on Why YC
the bump in valuation you get is bigger than the 7% slice of the pie YC takes.

People often seem to get too hung up on what percent they own. While you should pay attention to this, it's more valuable to direct your effort toward how big you can make the pie.

cornellwright··on The War on Cash
Are you serious? Every time I've been to Europe (I've lost count of how many times...) I've paid for many things with cash. I actually find it more inconvenient not to have cash there than in the US.
cornellwright··on Missing Malaysia Jet MH370 Weeks Away from Keeping Secrets Forever
It's only a little off. Services like Spot [http://findmespot.com/en/] offer satellite tracking with updates every 5 minutes while moving for $100 for equipment and $100/year for service. Spot doesn't quite cover the whole world, but Delorme InReach does [http://www.inreachdelorme.com/] for like $250 for equipment and $150 per year.

Given how easily available this technology is to anyone with a credit card, it's hard to understand how a $250M airliner doesn't have something similar.

Any member of the public (with a fair amount of money) could also just charter and fly a plane over the property and watch. While persistent surveillance would be incredibly expensive, it's still possible. A neighbor could temporarily install a pole with camera or allow another individual to do so.

In short, you have no expectation of privacy when it's possible to be seen from a public right of way. I really see no problem with what LE did here.

cornellwright··on Bad USB-C cable destroys laptop
Right, and either way the fact that this cable made it out of the factory to see the light of day says terrible things about this manufacturer.
cornellwright··on Bad USB-C cable destroys laptop
I wonder if this one cable was miswired or it's something consistently wrong with the product. Either way that something like that could make it out of the factory demonstrates terrible or no QA/QC.

I've never used the Twinkie but it looks pretty cool. This shows that it may be worth adding some simple protection to the circuit to prevent simple miswires from damaging it or the host PC.

cornellwright··on A Plague of Helicopters In New York
Back in 2009 there was a midair collision [1] between a tour helicopter and a private plane which sadly killed 9 people. If I remember right, there was some simple steps done to try to improve safety in the Hudson corridor, but nothing that really slowed down the growth of the industry.

cornellwright··on Heap on Embedded Devices: Analysis and Improvement
While it's nicely written, my first question is why are you running JS on a microcontroller?
cornellwright··on How to play Powerball so you don’t have to share the jackpot
If I remember right (and IANAL) you can deduct gambling losses from gambling winnings (but not ordinary income), so you'd only be paying tax on difference.
cornellwright··on Big Oil Companies Should Adopt a Self-Liquidation Strategy
I think the issue that this and a few other comments have is that by "self-liquidation strategy" the author doesn't literally mean sell every company asset as quickly as possible. It means recognize that the market for petroleum is going to decline and mostly go away before the OPEC states have all depleted their reserves. Therefore, BP et al should not invest in finding more reserves, and instead just focus on extracting all the money they can from what they have.

Note I'm not taking a stance on whether or not the author is right, but I think that if he is, there are enough players to prevent price gouging, and if anything we'd see prices fall due to no one wanting to be left with stranded assets.

cornellwright··on Access UART ports
Wow this is way more transparency than I'm used to seeing from Sony. Hopefully it's not just a one-off thing.
