Any reading of Tufte's claims about the Challenger launch decision should be accompanied by reading this article, one of whose authors is Roger Boisjoly, one of the Thiokol engineers who recommended against the launch:

https://people.rit.edu/wlrgsh/FINRobison.pdf

tl/dr: Tufte's analysis itself exemplifies the charge Tufte makes. Tufte presents the wrong information about the way the decision was made, in the wrong way, and that is what drives his conclusions. When the right information is presented in the right way, it is clear that the Thiokol engineers did everything they possibly could, and that it was indeed a case of management overruling good recommendations by engineers.

The article also gives very important background information: Thiokol had previously recommended grounding the Shuttle until issues with the O-rings that had surfaced on previous flights could be understood. NASA refused. So during the discussion the night before the Challenger launch, Thiokol could not make a number of arguments that would have seemed simpler and easier, taken in isolation--because they had already made those arguments and had them rejected.

The main author of Plan 9 was Rob Pike. He knows a little bit about networked software.

I actually had Plan 9 working on some Sun 3/50s at one point. You could use it over a 2400 baud modem... a kind of broken one where I had to listen to the connection noises and twiddle the wires at the right moment to make it connect. A bad cell phone connection would have been nice.

I am also Texan and I agree with everything you wrote in this comment. It's that you made a guess that the reason the study was commissioned was because the other ones weren't good enough for them. Which I have not seen anywhere. This new study "won't be good enough them" either. We can demonize the state handling of the issue while also praising any commissioning of studies in the area.

Font rendering has kind of stopped sucking on Linux lately. There was this guy making a package called Infinality which majorly improved the appearance of most fonts on Linux. His patches has fiiiinally been pushed upstream to fontconfig and freetype2 themselves.

But that's not the major difference between Android and Linux -- it's the DPI. Mobile phone screens have about four times as many pixels/unit of area compared to regular 1920x1080 screens. Run Linux on a HiDPI screen and fonts will look just as good.
I was being sarcastic. Democratisation = making flying available to everyone - in this case, by enabling unqualified crew to pilot a plane.

Google, as the copyright owner, could do that, or let hardware vendors do so, even if it was GPL.

Generally I agree, but it's definitely an area Amazon could improve on at times. They recently shipped me a 60cm steel rule in a box that was roughly 70cmx40cmx10cm.
It is not correct that a private pilot can be reimbursed for expenses. Pilots are permitted to share expenses for a common purpose.

The long standing (~30 years) rule is the pilot's share can't be less than their proportionally equal share, based on the total number of people in the aircraft. The pilot can't walk away from a private flight with a net $0 cost or it isn't really a private flight, the pilot is being compensated. And the passengers and the pilot need to be engaged in a common purpose activity, ergo it cannot just be about transporting people from A to B if the pilot has no need himself to go from point A to point B.

If the purpose of the flight is to test an app for the company, it is unquestionably a commercial flight and the pilots are employees for the app company. Depending on myriad other factors, the size of the aircraft and how many passengers are on board, a two pilot crew rule might apply and if so absolutely a student pilot does not qualify.
What I find intriguing is that the pattern merely acts as a background.. yet the plain wall at the start was already a background and did not discourage chaos.

Why does a plain background encourage chaos where a patterned background does not? My imagination may be in overdrive, but I think there are some interesting metaphors for why society works hidden in there.. :)

You're right that there are commercial flights that fall under part 91 rules. However in this case I think TapJets response was trying to say that their pilot didn't require a commercial rating, which would answer the FAA's claim of "a commercial pilot certificate was required."

You would do the same thing you do today. There's a few options, you could go to your primary care physician who would have a known price for an office visit. You could go to an urgent care type facility. You could go to something like a CVS Minute Clinic which has flat rates for "minor illness" visits. All of whom may discover you have something more serious and refer you elsewhere.

You are acting as if paying out of pocket at a price not determined by an authoritarian central planner would suddenly mean nothing in healthcare would be regulated in any way and people would be getting healthcare from crackhead joe in the back alley.

Not everyone will pick the cheapest option all the time. Today there are free clinics in many places. Most people don't go to those. Some people will choose Wal-mart. Some people will choose Macy's. And there will be a myriad of options in between.

Amazon's own couriers are the worst of the bunch for me (in the UK). They leave stuff pretty much anywhere, even if you're in, up to and including inside a general waste bin (which is great fun when you have pets to clean out and don't immediately notice the Amazon card...) and show up at pretty much any time (after 10pm on more than one occasion).

If I were tapjets, I would probably not want my legal counsel saying that tapjets is like airbnb and uber. 2 companies which continue to operate in sometimes murky legal areas.

" Just like Uber, Airbnb, and other successful companies that changed the status-quo, TapJets Inc. is now facing push-back by government regulators," said Debra Fein, Corporate Counsel for TapJets, " TapJets denies any wrongdoing, denies all allegations that FAA has made, and is prepared to vigorously defend itself against allegations despite it no longer being the need for TapJets to be a certified airline."

That $51,000 to the accountant covers payroll for at least a couple accountants and a secretary, the taxes and rent those individuals pay personally, the rent the business pays locally, food spent at local restaurants and grocery stores, and the taxes and rent those businesses pay. Rent and food make up anywhere from 30-50% of most modest income household budgets, so it's reasonable to believe 30-50% of that $51,000 stays in the community.

The impact the NOAA, VA, etc has on a local community of 100,000 is, barring a local employment center, 100,000/330,000,000*$51,000. It's not even close how much more of an impact paying your taxes to your local accountant instead of the government would have on where you live.

I don't think we need to posit a mustache-twirling villain here. They call it "skin in the game" because the idea, stated in plain terms, wouldn't be popular. If you strip away all the performative outrage that was the big "revelation" of John Gruber talking about why they started calling the individual mandate in Obamacare a "fine" rather than a "tax"; why wouldn't the same logic apply here?

But don't take my word for it; here's the Rand Corporation offering a studiously even-handed assessment and giving a definition of the term matching the one I suggested: https://www.rand.org/pubs/research_briefs/RB9672/index1.html

> These plans are intended to give consumers more "skin in the game" — that is, to make them responsible for a greater share of spending. Proponents of this approach contend that consumers in such plans will have more incentive to make prudent, cost-conscious decisions about using health care, which, in turn, should drive down overall health care costs. Critics, however, have voiced concerns that consumers lack information needed to reduce spending without reducing quality of care.

> We don't keep the three grand we save by saying, "Hmmm... maybe I'll just lose 15 pounds instead." That's how things are supposed to work.

Well, first of all, that's false, in the sense that, increasingly, deductibles are substantial (a few thousand, at least), co-pays are higher, and co-insurance (where it's difficult to even predict what you'll owe) is becoming more common. Almost nobody has a plan where they don't have to pay something for medical care.

But besides that, maybe in your scenario someone decides to lose weight. But let's think of another scenario. I start to experience some pain but I haven't really got the money for the doctor's visit. I decide I can tough it out. I keep doing this until the pain is truly unbearable and then I go to the doctor and find out I'm terminally ill and I waited too long to be treated. Or I forego preventative care and miss an opportunity to catch and treat cancer early. There aren't outlandish scenarios; they're the result of a system where patients have to shoulder more of the cost of care out-of-pocket, especially when combined with a state of affairs where a great many Americans do not have the savings to pay an unexpected expense of a few hundred dollars out-of-pocket.
> Looking at the memos and slides that were presented up the chain, it's not very surprising that the correlation between temperature and failure was lost on its way up the bureaucracy.

One of the points made by the article by Boisjoly et al (linked to in my other comment just now) is that "the correlation between temperature and failure" is hindsight (and incorrect hindsight at that--see below). On the night before the Challenger launch, nobody knew exactly what the problem was. That was not for lack of trying on the engineers' part: they had repeatedly requested more data and more experiments with the O-rings, and been refused.

The basis of the engineers' recommendation the night before the Challenger launch (which, as I noted in my previous comment, must be considered in the light of the fact that they had already recommended grounding the Shuttle until the O-ring issue could be understood, and been refused) was not "the O-rings will fail in sufficiently cold weather"; there was not sufficient data to show that. The basis was that, in the absence of an actual understanding of the issue with the O-rings, no launch should be attempted outside the range of temperatures previously experienced.

The reason "correlation between temperature and failure" is not correct hindsight is simple: as noted in the Boisjoly et al article, both test data and flight data had shown failures of the O-ring assembly at higher temperatures as well as lower temperatures! To understand how this could be, one needs to understand the root problem with the O-ring assembly (another item that Tufte's analysis gets wrong). The root problem is that, as the SRB fires, the gap between sections, which is supposed to be sealed by the O-ring assembly, expands. The O-ring assembly also has to expand, fast enough to keep the gap sealed; if it doesn't, hot gas can escape.

It is true that the speed at which the O-ring assembly can expand gets slower as the O-rings get colder. However, it is also true, looking at the data, that even at temperatures as high as 75 F (and possibly as high as 100 F--the data is not conclusive), the O-rings already were not expanding fast enough to keep the gap sealed! In other words, based on a proper understanding of the root problem, pretty much every Shuttle flight with this O-ring assembly was rolling the dice. And, of course, there were indications of a problem on a number of previous flights, which were raised as issues by the Thiokol engineers and ignored by NASA.

You would only need to sandwich the intercooler between the hot and cold heat exchangers with a (fairly powerful) automotive refrigerant pump connect to them. The cold heat exchanger would go in front of the intercooler.

The answer is you choose a car based on personal experience, referrals from friends, and trusted third party reviews. That's exactly how you choose a healthcare provider today.

There is no magic here just because healthcare is more important than car choice. You're no more or less safe because you're paying out of pocket. It's not as if paying out of pocket means you're going to be getting healthcare from Joe the crackhead in the back alley. It will still be doctors, NPs, etc. all licensed in your state.
This, yes. Also, if you're processing discrete items in any measurable way (downloading kilobytes, ingesting database rows, querying servers...) that takes longer than one second flat, display that to users. "Processing record 1/1,000,000... Processing record 2/1,000,000..." gives a positive sense of progress. Even if you don't actually know the final total in advance, you should still display whatever you've got.

As a bonus, this can occasionally be useful for bug squashing. "I've been waiting for hours and it's only up to row 5681" when you know for a fact that there's <2000 rows is a lot more informative than "My report won't finish."

There are two things that have stopped me from using CloudKit in my apps in the past: 1- Despite Apple's generous free tiers, the cost of data transfer is on the app developer, and not on the user. As a developer, I see this as a liability risk. 2- Data is either completely private or completely public, there is no intermediate "team" or group that can be easily set up to share data among users.
This will work really well at small scale. As you start to make large volumes of queries against major email service providers, they will start blocking you. It then becomes a cat and mouse game as you move IP address is constantly to try to avoid detection. The only long-term strategy for recipient validation that actually works is to partner with somebody who sends a great deal of legitimate email, and mine their logs.

In certain respects, it doesn't matter if it's a bubble. Sequoia's job is to allocate funds across the tech industry. Simply by giving them money to invest, their LPs accept the risk of systemic issues that could result in the entire tech industry crashing.

In part this is allowed by the fact that most LPs diversify their funds, so they're not completely vulnerable to problems in a single sector. It's also because funds are rarely judged against absolute return; they're judged against benchmarks. If the entire market falls by 10%, and a fund only falls by 8%, then they're still doing well relative to their benchmarks.

But what's more important to Sequoia is not missing out on returns. LPs aren't investing so that Sequoia will keep them from losing money. If that were their primary goal they would just invest in CDs or government bonds. They're investing with Sequoia so they don't miss out on the upside. And if that's the priority, and Sequoia's competitors have far more money to allocate (see SoftBank with their $100 billion fund), then Sequoia also needs more money to allocate to stay competitive.
> Messaging apps are the third phase of platforms on which digital audiences congregate. First came websites, then social networks and now messaging apps—which collectively accounted for 7.7 billion monthly active users (MAUs) at the end of 2017, up from 6.6 billion in 2016 and 5.5 billion in 2015. This is a massive segment that continues to grow at pace.

That's a pretty misleading claim. I guess I sort of understand what's being expressed here, but it feels weird to just add up every platform's monthly active users and come up with a number larger than the population of the Earth.
> The reality is that if you are ever in this situation you should ALWAYS negotiate. There's a reason medical debt is bought for pennies on the dollar.

I wonder if it's possible to buy your own (or a close friend's) medical debt). If someone has to pay $200000 in debt, but could buy that debt for $2000, then that may be the easiest way to "pay it off".

Most places in the UK do as well (it's mandatory online), but Amazon tend to deal with returns outside that initial period much better. I recently had a pair of headphones break after 17 months use - still in warranty but I wanted to avoid the manufacturer if possible due to the 2 week turnaround time and the fact that Amazon listed them as "Used - Like New" (Warehouse Deals). In similar situations, other retailers have either been extremely awkward about the exchange or insisted that the manufacturer do the repair. With this one, one email to Amazon and less than twelve hours later I had a returns label and a refund on the way.

It's still worth shopping around - occasionally Amazon can be far more expensive than the alternatives - but if the price is close, _knowing_ that Amazon will sort an issue even if it doesn't show up for a year plus without even questioning is useful to know.
What’s odd is my experience with cancelling Prime is the same with getting rid of my Facebook. Once I got rid of it I was happy and didn’t miss it. Having no prime just means I lose out on instant gratification (well 1-2 day delay becomes a week). I also did not use prime music or video, so they didn’t have their hooks in me.
Fundamentally the analogy doesn't work because cars can be replaced. I can't trade in my body because the doctor can't figure out what's wrong with it and it's getting too expensive to keep getting care.
