I worked briefly as a bike mechanic and spent some time working on old cars. During that time picked up a mild fascination with failure analysis and one or two tricks.

If a bolt or a flange fails, you can look at the oxidation patterns and see if the failure happened all at once or over time. Most of the times I encountered a piece of metal where only half of the fractured surface was shiny, indicating that this piece has been failing for quite some time. It's a bit unsettling to think about how many fasteners around you might be in that state so I... don't. But there virtue in disassembling and reassembling old equipment, and inspection is certainly part of that.

My buddy in college was in the ME program and he came to me excited one day because he'd just learned about metal failure and figured out why airplane structural members have so many holes in them. Weight, of course, but also it turns out the shockwave when a crack starts can propagate the crack, not unlike how breaking 5 boards karate style is only about 2x as hard as breaking one. If that force hits a hole in the material it travels around the circumferences and it acts more like a spring. Thus drilling a hole in the end of a crack to stop it.

So a localized flaw in the wrong spot in the material can start a fracture, and spread into material that's up to standards.

If I remember my physics at all, there's more torque on the end of the beams, so in theory a crack could start anywhere but it might be more likely near the ends. Still, a crack that close to a weld seems pretty sketchy. If I saw that in a bike, I'd presume the metal was damaged in the assembly process. I encountered cases of both materials defect and manufacturing defect. In particular a case of bad epoxy from Trek (assembly) a couple years before excessively anodized aluminum rims showed up on Cannondales (material defect).
Their position seems to be that they don't need to compensate because he's already getting paid by the insurance company.
I assume a sunshade in space would need to stay oriented as the Earth revolved around the Sun in order to deflect the sunlight. Therefore "take down" could simply mean disable the orientation equipment.
Isn’t it perverse that we need such optimization techniques so that we can sit at a desk all day.

I think it’s a wonderful technique but it makes me wonder why and if we’re just -not built for this-.
Very interesting. It some kind of sense to me that the noisiest customers are those paying less, even if they're only making up something like 20% of actual MRR.

Are a lot of the support requests related to yearly billing or do you mean a quarterly option would theoretically preempt those kinds of requests?

Really great extension, site and all-around product, by the way.
Eh. You can literally do a PhD anywhere (in western countries) and as long as you're good and your skill set is complementary, you will find a good job in industry science. Going to a top-tier university for a PhD may get you a better network, but ultimately when I hire I really don't pay attention to where the degree comes from. Nor do I care about papers beyond did you get your name on (any author position) at least one during your graduate work. The key is complementary and practical skill sets and being able to speak passionately about your work--even if it's arcane or boring.

vfork is perfectly predictable as long as you follow the basic rule: only invoke async-signal-safe functions until you call exec. they're explicitly listed but basically boil down to: any functions that more-or-less map directly to a system call, and nothing that could possibly modify process memory or attempt to take a lock (including memory allocation)

it's meant for cases where you want to avoid a bit of the fork overhead or if you need to spawn a subprocess from an existing memory-heavy process without getting a KILL from the kernel if overcommit is disabled (as the fork COW doubles your claim on memory even if you don't actually trigger a copy)

The Inquisition certainly wasn't the worst thing the humans have done, no. I didn't mean to suggest it was. Its infamous crimes need no exaggeration to earn their prominent place in the pathetic catalog of human vileness, though at times that has been no obstacle to those motivated more by hate for Catholicism than by wisdom, compassion, or personal integrity. But the bare truth is heinous enough.

I brought it up because the centuries-long intellectual blight that resulted from it is a salient example of the corrupt fruits of the poisoned tree of state censorship, a tree whose root in European history is that very Inquisition.

Rent control is often seen as counterproductive -- a disincentive to creating more housing.

What if it's the reverse?

The supply of land is fixed. Its intensity of usage is not.

By imposing a per unit rent cap, what's effectively happening is that a rule is being established that no more rent than that cap can be extracted per unit. But there's no inherent restriction (zoning, construction laws, etc., being of course the exceptions) to more intensive development. Increasing the unit count.

A rent cap plus zoning restrictions is one form of death: there's no new housing supplied, and if the issue is rent control (limited rates of increase over tenancy), then the result is similar to what happens in San Francisco.

But with sane zoning and construction standards and a cap, you're inducing more intensive development -- an increase in housing supply -- by imposing an arbitrary per-unit revenue cap. And without nominally raising taxes, the bugbear of the land value tax approach.

I'm not aware this argument has ever been proposed, though I am fairly confident it has been.

> I was shocked that anybody was shocked.

I agree, and I also think that's why there's no widespread outcry about surveillance among the general population. For example a lot of baby boomers grew up with "party line" telephones. I did, rural areas in the 80's still had them. You get used to idea of someone listening. I'm not saying this makes it right, just that it could explain the ambivalence of many.
Many people consider it a walking distance. If you go on foot both ways but sit 8h at work you can still find it dificult to hit 10k steps per day (WHO recomendation IIRC).

> The results of the elections and the independence referendum strongly disagree.

The turn out in the 2017 one was 43% and iirc at the time those against the referendum were encouraged to and did sit out as a way of saying 'this is not legitimate' which kind of muddies the water a bit on the actual numbers. [0]

https://en.wikipedia.org/wiki/2017_Catalan_independence_refe...

[0] Of course this is the problem with any low turn out election, how do you account for the people that don't turn out? Are they protesting, happy with either choice or something else?
A judge can order Tesla to stop distributing GPL'ed code. Which means they couldn't sell Teslas with it or ship firmware updates to anyone with it.

Source: https://lwn.net/Articles/61292/

Relevant part:

> You do have a choice under the GPL: you can stop using the stolen code and write your own, or you can decide you'd rather release under the GPL. But the choice is yours. If you say "I choose neither," the court can impose an injunction to stop you from further distribution, but it won't order your code released under the GPL. Your code remains yours, as you can see, even in a worst case scenario.

Well really the whole article is relevant. It points out that the GPL is a license to use the GPL'ed code. If Tesla violates the conditions of that license, they can lose the right to use that code as a result. IANAL though.
I strongly agree! I often wonder why a big alliance of industrial companies (say Ford, Toyota, Airbus, Mitsubishi...) hasn't formed to create a high-performance open-source mechanical CAD, modelling software. Surely they each pay a fortune in proprietary licenses each year? It seems like it would save them a lot in the long-run to back an open-source standard and then just pay a small amount each year to support its maintenance.
> You do realize that police keep investigating crimes and tracking down suspects afterwards, right?

You realize that most shoplifting suspects are never caught, right? Some stats suggest a 2% chance of actually catching a shoplifter after the crime. Letting them go at this point means 98% chance that they'll get away.

For the officer: keeping up the police chase is your best bet. You keep chasing until the Helicopter comes in, and then the Helicopter can follow the car no matter where it goes.

This is why criminals force a high-speed chase, because they can (and often do) get away with it (as long as they disappear before the Helicopter arrives). The mistake for the criminal here was shooting at the Police Officer, which enrages officers to a severe degree. Once you apply lethal force to officers, they'll chase you down basically forever.

I'm running uBlock origin and I'm not sure what you're talking about, the original looks normal to me?
You're comparing the average Dutch person vs a hypothetical average American to say it's a huge difference, but obviously the "average American" is going to be orders of magnitude lower as the vast majority of Americans don't bicycle regularly.

The article already points out that a much higher proportion of people in the Netherlands bike.

"The Dutch hardly bike at all" refers to an individual cyclist compared with an individual cyclist in the states. To someone who does bicycle regularly, 1.5 miles is, indeed, hardly anything at all. I bike 1.5 miles in each direction to my train each day (so twice that average) and don't consider myself to bike far at all.

I guess at worst you can say it's a click-baity title, as it's appearing to go counter to your expectations of a heavy biking culture (which it is) to say that any one cycling individual doesn't actually bike far, but that shift in perspective is the point of the article.
Normally didn't do much in the partial class other than reference it.

You could override what it was doing in the main class file though if needed pretty easy. Again if it did break it was just aode and threw a normal exception in the designer, usually revolved around something that didn't work right in DesignMode so you had to check for that explicitly.
You've completely missed the point of the article. The point is that the Dutch use bicycles a lot because their urban infrastructure means many of their trips are the right length for a bike to make sense over either walking or driving.

The Dutch are not insane fitness nuts biking 25 miles to work daily. They just have a built environment where taking a bike actually makes sense because they aren't going terribly far, just far enough that the hassles involved in taking a bike (like locking it up) are worth it.

>Summary: Dutch biking rates are highest for trips of about 1 mile, and when trips get longer than three miles, bike trips start to fall sharply while car trips rise.

The summary and the graph supporting it are startling. I think in my city you see a very exponential increase in car transportation starting past the average distance we cross the parking lot, about 500 feet.

Those conclusions are taking the available detail of the current proposals to conclusion.

I seriously doubt that any proposal would pass that results in such a conclusion. The point the article is making is that the proposals need to consider the facts that result in that conclusion (ie, current Medicare/aid rates cannot support the current industy), and need to offer proposals to counter act such a conclusion. Any proposal that doesn't is not a proposal, but a platitude.
This is great logic.

"Sure, my house is valuable now, but if I could also walk to a grocery store, a barbershop, a coffee shop, an electronics store, a beer pub, a few restaurants, and a few other kinds of stores, AND get on public transportation that would take me to local hubs and office spaces -- surely my house would drop value like crazy then!".

Greater logic: people looking to rent a small, inexpensive apartment are clearly the same people looking to buy a house with a backyard, so increasing the supply of the former would decrease prices for the latter by the law of supply and demand.

Exploding brain logic: ignoring property values going up every time the subway/local rail starts expansion into an area. Also voting against public transport expansion because nobody is using it anyway. AND also voting against constructing dense housing, because it will increase traffic.

Note that all three are required to block mixed-used dense walkable developments on the premise of "my property value" --- and that all three currently apply to the Bay Area.
Illegal and forbidden are not synonyms. Political actions especially with respect to territorial integrity can both be illegal and allowed to happen i.e. not forbidden.

Scientific Jury Selection
Green Bank Observatory does not intentionally transmit, and any leakage would hardly exist for long, since the whole point is to listen to extremely weak signals.

However, a radio telescope differs from your usual radio receiver in that the stages are often separated by vast distances. I'm unfamiliar with the exact signal chain used in GBT, but I do have plenty of experience with a similar scale telescope, the Arecibo Radio Observatory.

A radio telescope will go to huge lengths to reduce the system noise of the receiving elements, including cryogenically cooling the receiver and first few stages of amplification. These signals will then often be brought down within a shielded enclosure (often within a shielded receiver room) and shifted into their intermediate frequency (IF) stage with a highly pure local oscillator (LO) signal and brought back down to the control/electronics building.

In the case of both GBT and Arecibo, that IF is brought down as modulated light over fiber optics, meaning that there is no RFI leakage possible on the transport. And at both, the conversion back to IF is done within a shielded room. At GBT, if I remember correctly, that room is within the Jansky Lab, which was designed as a shielded building.

All of this is to say that it's very unlikely that there is any signal at all transmitting out of the telescope system in any way.
Did you read the rest of the article? The entire point of the article is that by one measure, the Dutch hardly bike at all, while by another measure, the Dutch bike all the time, and that the difference is that there are destinations that makes a mile or two round-trip plenty in Dutch cities, but not in American cities.

Why would he not be able to do that? He had access to his lawyer, right? Or why would he not be even more upfront and straight up tell the prosecution that someone tried to kill him and that he would spill everything for protection?
> I mean, why try to do anything? [...] compromise [...] severe lack of funding

I agree with the challenge, but suggest parts of the compromise are not being squarely faced.

Have you seen a Jackie Chan action film, where mixed into the ending credits, is a blooper reel of stunt fails and injuries? It serves to correct the reality distortion of the film itself, to reduce viewer injuries from emulation misjudgement. If Hollywood held itself to a similar standard, there would be less paralysis from "we had to move them, before the car exploded", and less drowning with "but... it was so quiet".

A microbiologist writing a young children's picture book, included an errata page. Describing the liberties taken, and at least some of the errors made. And if just maybe, one might uncharitably suggest that maybe it was motivated a bit more by concern for being seen by ones colleges as having made an mistake, and perhaps a bit less for the conceptual integrity of readers, still it served to remind of the latter, and perhaps helped.

Yes, resources are always limited, and engineering and content creation are fundamentally about tradeoffs.

But you know how expense escalates, as one moves from thought to sketch to storyboard to crufty draft to professionally polished prettiness? That means one can always afford to add something crufty, if motivated to do so.

I'd have no problem if people said, "yeah, we could have reduced that misconception, but given our resource limitations, it would have been an unprofessionally hackish job mixed into our otherwise nice work, and we prioritized polish over the misconceptions, which maybe sucks, but it has to be viable as a product".

But I've never heard that. I've never heard "we prioritized polish over student outcomes". But I have heard lots of comments about software limitations, and pedagogical constraints, and so on. But the implicit constraining context, that "pretty" is prioritized as more important than "works", that's usually not looked at straight on.

And sure, part of that is the dysfunctional way that content is created, which in turn results from the way it's funded. I talked with a PBS science creator, who commented, sure, we'd love to try iterative creation and testing, rather than creating a thing, tossing it over the wall into the world, and never being sure how all our efforts and tradeoffs actually worked out... and just as soon as we find someone willing to fund that, we'll try it.

So my suggestion is that if we were more heads up about our choices, and their costs, we might be making different and better choices.

Why would that be the case?

> Wanna use JavaFX? You have to jump to Java 11 and hope your dependencies don't fail with module packaging errors.

Dependencies which still fail with module errors are basically abandoned and should probably be replaced. But even for those there's an escape hatch if you really want to continue using them, so that seems to be a non-issue?

> The Java tech stack is awesome when it works, but to solve issues you have to go so deep into the tech stack that I'm starting to think it just can't be done unless you're at least a mid-sized company with JVM specialists on the payroll. Not developers, but systems people.

I've worked either directly or indirectly with so many companies of all sizes using Java without any dedicated JVM specialists I'm pretty sure you're doing something very, very wrong with all the problems you seem to have.

I think his point is the science would be better served if it focused on solving problems for people, rather than exploring knowledge for the sake of it. But really I think that is the realm of engineering, and science is really just pursuing knowledge for the sake of it. It's impossible to know what will be useful - Richard Feynman thought it would be fun to analyze the flight characteristics of a flying plate. He later used the math he developed doing that to help him earn a Nobel prize.
