    For an object heavier than the Earth, 1g radius will be greater than the radius of Earth. For 56 Earth masses that’s sqrt(56) times bigger = 48000km.

    A 56 Earth mass black hole will take 5.5e55 years to evaporate according to this calculator. A 100kg black hole (more close to what Richard used to be) is much smaller than the nucleus of an atom and will evaporate in 0.05 nanoseconds.

    Curiously there was a paper recently that calculated that even if there was a small black hole in the center of the Sun, it would take millions of years for it to grow, because the aperture is so small not much can fit through, and the infalling gas heats up so much as to repel the rest, creating an internal hot bubble.


  • By some argument, section 103 of the DMCA (which is what grandparent post is referring to) does make it illegal to even talk about DRM circumvention methods.

    illegal to: (2) “manufacture, import, offer to the public, provide, or otherwise traffic in” a device, service or component which is primarily intended to circumvent “a technological measure that effectively controls access to a work,” and which either has limited commercially significant other uses or is marketed for the anti-circumvention purpose.

    If youtube implements an “access control measure” by splicing the ads with the video and disabling the fast-forward button during the ad, and you go on a forum and say “Oh yeah, you can write a script that detects the parts that are ads because the button is disabled, and force-fast-forwards through those”, some lawyer would argue that you have offered to the public a method to circumvent an access control measure, and therefore your speech is illegal. If you actually write the greasemonkey script and post it online, that would definitely be illegal.

    This is abhorrent to the types among us for whom “code IS free speech”, but this scenario is not just a hypothetical. DMCA has been controversial for a long time. Digg collapsed in part because of the user revolt over the admins deleting any post containing the leaked AACS decryption key, which is just a 32-digit number. Yet “speaking” the number alone, aloud, on an online platform (and nothing else!) was enough for MPAA to send cease and desist letters to Digg under DMCA, and Digg folded.




  • Street space is a public good. It is literally land, surface area to be used for something. You can’t create more of it short of demolishing all the existing buildings. Right now like 80% of the width of a Manhattan avenue is dedicated to moving and parking cars. Pedestrians and bicyclists are squeezed into tiny slithers on the sides. It’s a total shame. If you count and compare the number of people passing a given point on a 5ft busy Manhattan sidewalk to the number of passengers in private cars in the 55ft roadway next to it, it’s like a 10-fold difference in 1/10th the space.

    Right now, everyone poor and rich at least has an equal access to drive on the roadway (assuming you can afford to maintain a car at all). However, midtown roads are already at full capacity all the time. There exist way more people in New York who would drive if they could, but they literally can’t fit. It takes 1-2 hours to drive into Manhattan. This is considered “typical traffic conditions”. Morning rush hour stretches into the afternoon and merges into evening rush hour.

    Effectively, you are trading patience/time for the opportunity to drive in. For every one person who has the patience to wait 1 hour in gridlock, there are 2 more who do not and find alternative ways in. Even billionaire mayor Mike Bloomberg took the subway to work. It was described as “populist signaling” but it was literally faster for him than taking a limo.

    Rich people have a lot of money and not a lot of patience. Lots of them would have loved to be able to pay to skip the gridlock, but they couldn’t, until now. They have succeeded in taking this 80% of public space, that everyone with sufficient patience could access, and turning it into a private toll road. That’s why this is a land grab! Doesn’t matter if the fees go into a public fund - if revenue was needed it should have been raised by a progressive tax. A flat fee is the opposite of that!

    The congestion charge will not even decrease the number of cars on the road. Remember how for every 1 driver there are 2 more who wish-they-were-drivers but who had more money than time? Every 1 poor driver taken off the road will be immediately replaced by 1 more private car service Suburban SUV. The rich crave travel away from us poors, in their padded armored tanks, and now they can do exactly that, as they have succeeded in having the legislature kick us off our public land.

    The only thing that will reduce car traffic is shrinking the roadways. Take those 5-lane Manhattan avenues, take away one lane and convert it to protected micromobility lane. Take away another and widen the fucking sidewalks! Take away the street parking and convert it to green space with trees that survive longer than 1 year. Add loading zones for delivery drivers. Use the public street space for the benefit of the actual public!







  • That’s why Google is pushing hard their Web Environment Integrity. It’s DRM for the browser! They want the TPM chip in your computer to attest that the code running processing the video stream is authentic. Then you can’t slice out the ads because you do not have physical access to the inside of TPM. With HDCP encryption on the HDMI video output, you gonna need to point a literal video camera at the physical screen to DVR the video and slice out the ads later.

    They’ve been working hard for decades to lock down the video pipeline with TPM and HDCP and now WEI. They said “don’t worry about it” and we let them. They are really close to snapping the trap shut!

    Now please excuse me, my tongue is falling off with all the acronyms…




  • Oh yeah, the app is probably even more convenient, especially with the pre-checkin, and the hygiene too, but there is no way I’m using that tracking bundle 😂. When I was born, nobody was counting how many burgers I was eating, and I’m not going to allow that to change. It’s a shame too because they hide all the actually good deals in the app, the ones that make eating there actually affordable, so I find myself not even going to eat there anymore. I feel like a rube paying the full price. Probably better for me in the long run anyway.


  • I don’t see why you are being so stubborn about this. If you don’t like the numbers I gave you because “you can still go up to the counter and get a real person” it’s an easy adjustment to make that tells the same story: before kiosks = 5 people working 75% at food and 25% at register, after kiosks = 4 people working 95% at food 5% at register. The conclusion is the same - your claim that automation does not eliminate positions is simply incorrect. I thought maybe you had some insider knowledge on mandatory staffing levels, but it seems you are just bad at math. Everyone else in these comments was arguing about jobs disappearing (not me! I only wanted to show off the cool cashbox) - it must have been really confusing to see all those people upset about something which you can’t even comprehend as a problem.




  • We can keep the supermarket cashiers, we just have to demand it. Always choose the full-service line, and complain loudly if there are not enough cashiers to keep the line short, scoff at any suggestion to use the self-checkout and demand to speak to a manager and corporate. As I said elsewhere, one person can only do so much, but when a million people keep doing it the mountain will have to move. I feel personally responsible for the installation of these cashboxes by insisting to pay in cash every single time for the past several years.


  • Literally starving to death is more difficult nowadays than in the past, but every society is still structured around the idea that you must be doing something wrong if you are not employed. Food, housing, healthcare, all tied to employment, and the substitutes they maybe give you are designed to only barely keep you alive until you find more employment.

    Yes, every job that has become obsolete in the past due to automation has been replaced with a new kind of job, many of which could not have even been imagined before. We don’t have buggy whip manufacturers, but we do have programmers. But that doesn’t mean that will continue always. Jobs that disappear now or in the near future may never get replaced. And many jobs that exist now, I’d argue, are totally bullshit already, and we don’t need more of them. We as a society need to reassess our expectations for 100% employment and better reallocate resources according to the new norms.



  • They’ve been the most vocal opponent to $15 minimum wage increase in New York, which I’ve always found odd, since they’d be the ones to most benefit from it via competitive advantage, as you said, due to economies of scale. They’ve been making threats the entire time “We’ll replace cashier with computers! If you raise the wage, we’ll totally do it, you’ll see!” and I’m like “Dude, if you had the capability to do it, you gonna do it either way anyway, why you extorting us?”

    I guess the smaller competitor restaurants will need to get kiosks as well. They can’t develop their own in-house technology like the big chains do, but they can still purchase 3rd-party ready solutions, like all of them have already done with online ordering. Slightly more expensive to use 3rd party, but that’s economies of scale for ya.
