razorunreal··on These are called opportunities
If companies like Apple didn't try to make things as incompatible as possible, maybe software engineers wouldn't have to keep adding new layers of abstraction and things would run a bit faster. There's basically a never ending war between platform developers trying to create lock-in and app developers trying to escape with new cross-platform technologies.
razorunreal··on The CDC lost control of the coronavirus pandemic, then the agency disappeared
It seems very relevant because the military was apparently completely unprepared for biological warfare. Like in all their talk of terrorism they hadn't even considered the possibility. Sure, this virus wasn't an intentional attack, but it easily could have been. How much good do all those weapons do when a virus can bring the country to a halt?
razorunreal··on Programmers generate every possible melody in MIDI to prevent lawsuits
Without being any kind of copyright expert, this argument doesn't make much sense. If you have the relevant indices into pi, I guess you could claim copyright. The index will be much larger than the original book though. Essentially you have a really bad compression algorithm. I'm not going to get very far claiming that because my decompression algorithm could output any sequence, all sequences are mine.
razorunreal··on Letting slower passengers board airplane first is faster, study finds
Seems to me the real problem is people in the same row who don't board together, since frequently someone has to squeeze back into the isle and block things until their neighbor is seated. Airlines know who booked together, couldn't they optimize the boarding groups flight by flight? If some people booked together and sit together, give them all the earliest boarding group that any individual member would have had.
razorunreal··on The Big Problem with Wealth Taxes
That seems fair to me because it results in a tax based on how much the property is worth to you specifically. The "value" may be inflated from real market value, but as long as that is true for everyone it doesn't matter.

Also if it's too much of a burden to value all these assets, you can list them publicly and let people bid. If you expect the government to protect your ownership rights, I think it's not too much to ask that you list your major assets.

razorunreal··on Can You Overdose on Happiness?
I think our emotional responses exist to guide us towards good decisions. If you take a reinforcement learning system and you always give it positive reinforcement, it will not learn much of anything. I guess I'm saying your enlightenment is irrelevant if it's not improving your survival.
razorunreal··on Android 10
It's a setting, you can keep the soft buttons if you like.
razorunreal··on Many Americans who live paycheck to paycheck blame debt
I think people forgot that a 10 year old car means 2009. Newer cars are still safer, sure, but that's easily recent enough for good crumple zones, strong pillars and plenty of air bags, all for under 10k.
razorunreal··on World’s top bicycle maker is moving U.S. orders to Taiwan factory
This is actually weird to me. It seemed like it should be possible to stamp out bicycle frames like a car, so I researched it. Such a bike does exist, but is extremely expensive, which seems to defeat the purpose. Is it really not possible to streamline the manufacturing beyond welded tubes?
razorunreal··on Fast constant-time GCD algorithm and modular inversion
So binary search is not logn time because it only reads logn values from the input? To know which parts are not read you basically have to run the algorithm. I find your definition unhelpful.
razorunreal··on Changes to Models S and X allow them to travel longer without larger batteries
Internal combustion engines throw off heat whether you want them to or not, plus the total amount of energy stored in a gas tank is vastly greater than a battery, so wasting some of it as heat is less likely to strand you. EVs only get similar range by being much more efficient, and efficiency means less energy lost to heat.
razorunreal··on Appl Still Hasn’t Fixd Its MacBook Kyboad Problm
Funny you mention magsafe, because that was defective too. They settled a class action but didn't actually fix anything. It would slowly toast it's own cable (probably due to dust in the connection) until the insulation frayed and you had to buy a new charger. Of course they would blame you for abusing the cable.
razorunreal··on Google Moves to Address Wage Equity, and Finds It’s Underpaying Many Men
I think you are asking the wrong questions. Why not ask: Why are there so many men in tech?

To answer that I would compare it to a field like finance, where people are well paid and over worked. I think the money comes first, then the men, and with them the bro culture. So my hunch is that men will disproportionately do anything for a dollar. And no-one notices because they are busy wondering where the women are.

razorunreal··on Pathfinding.js – Visualizations and Playground
Feel free, it exists to be read. And you just gained a subscriber.
razorunreal··on Pathfinding.js – Visualizations and Playground
If anyone has a tougher path planning problem and needs a better heuristic, I wrote an article a few years ago that might help: http://razorcode.net/articles/vehicle-path-planning.html
razorunreal··on Insurance Company Says NotPetya Is an “Act of War”, Refuses to Pay
I tried finding data on insurance payout/refusal rate when I was considering switching to a cheaper but lesser known car insurance company. It doesn't seem to exist. So much for consumer choice.
razorunreal··on Fundamental rule of traffic: building new roads makes people drive more (2015)
Look at big cities around the world and you'll find buildings with retail at the bottom and office space further up. I don't think it would be an issue, unless you stroll around the sky at night.
razorunreal··on China ‘Is the Only One in the Race’ to Make Electric Buses, Taxis and Trucks
Redistributing money from people who use more to people who use less is an incentive to use less. It can be an arbirarily large incentive depending on how much you decide to redistribute. It's not like the money is destroyed or something.
razorunreal··on Bus Lane Blocked, He Trained His Computer to Catch Scofflaws
If that's true, then in Manhattan the cars should go. Even as a pedestrian it is frustrating to wait for cars at the end of every short block. I'm not sure how gridlock is helping anyone, they should just ban anything that isn't commercial or a taxi from most of the city. If you want to live in Manhattan and own a car, fine, just don't bring it in.
razorunreal··on What Airbnb Did to New York City
If Grandma needs subsidized housing, that is something that should be separately agreed upon and implemented, presumably from tax revenue. The idea of forcing landlords to pay that subsidy basically at random seems ridiculous to me, the kind of thing that results in discrimination and legal fights.
razorunreal··on How poverty changes your mindset
This is the kind of thing that needs an institution (government or not) because otherwise the money goes to the most convincingly miserable looking people, not the ones in need. It's hard to prove, but it seems like most of the "homeless" on the NYC subway are just doing an act like the rest of the buskers. There's money to be had, and they've made a job of figuring out how to get it. If you can be sure that the problem is competently handled by the government, you can ignore people asking for handouts and not encourage that behavior.
razorunreal··on Physics Makes Aging Inevitable, Not Biology (2016)
I think they've got the evolutionary argument backwards. Rather than the older generation aging and dying because there is some evolutionary reason why they should, I think there is simply not a strong enough reason why they shouldn't. Why fix the remaining aging bugs when you already live long enough to reproduce and pass on knowledge?
razorunreal··on How NYC’s subway got wireless in the tunnels
24/7 "service". Sometimes I feel like I'm stuck in the middle of a tunnel just so some middle manager can claim that the line is still running. I would prefer they closed the thing at night and put some serious effort into improvements.
razorunreal··on The insane amount of backward compatibility in Google Maps
Some tips, just in case they help. When disabling apps, you can generally ignore the warning that other apps may break. Do not disable Google play services, though. Also, go into the account settings and make sure sync is turned off for everything, you can sync manually when needed. Finally, disable auto-update in the play store. Google apps update frequently but will generally continue to work for quite a while if you refuse those updates.
razorunreal··on “We Are Morons” – A quick look at the Win2k source (2004)
That's intentionally misleading. If it's not largely accurate the disclaimer should be "inspired by".
razorunreal··on Man who stole $1M bucket of gold details escape from US
You don't have to tell anyone if your face is on the news.
razorunreal··on How a Single Mechanical Failure Sparked 625 MTA Delays (2016)
That's what they do in Hong Kong, a nice glass barrier. Solves the trash on the tracks problem, plus people can't fall down there.

My guess is that requires a precise stopping position, which requires a proper control system, which they probably don't have.

razorunreal··on FAA Issues Emergency Order of Revocation Against TapJets
Having lived in both countries, Australia doesn't seem to have the inflating vehicle size problem to the same degree. Plus the attitude to welfare is very different in general. I don't think you can just transplant laws and arguments from one to the other and expect them to make sense.
razorunreal··on Like an AI Could Ever Spot Sarcasm
Easy. "Don’t they make you proud to be British!" is incongruous because nobody is proud to be British!

(I jest, please don't kill me)

razorunreal··on Tesla employees say Gigafactory problems worse than known
Have you asked them if they can just pay it out? It might mess with their budgeting slightly, but they'd be paying the same per hour worked so likely not be a big deal.
