3JPLW··on Long Before Boeing 737 Max Crash, Ethiopian Air Pilot Warned of Dangers
You know how you make it known to pilots? Not by reading the news. By having the manufacturer issue an airworthiness directive. And Boeing did. And yet it did not prescribe what you're advocating. Are you suggesting that you — a non-737 pilot — know better than not only the pilots in the crashed planes, but better than Boeing as well? Their AD does not list your homegrown procedure as a remedy.

You know how else to make it known to pilots? By making it a part of their training materials. But Boeing had significant financial interest in not doing so.

> In both cases, the pilots didn't strictly follow procedure

But would "the procedure" actually have saved the plane? I don't believe so. WalterBright is arguing that the pilots should have known better than "the procedure" and done something different from what the checklists and memory items proscribed. I can't comment on doing so — as I'm not an airline pilot — but to put blame on pilots in this sort of situation without acknowledging Boeing's actions is beyond tasteless.

IMHO Boeing is 100% responsible for the deaths.

3JPLW··on Scene report from the Chernobyl Zone
In the context of a drama about the explosion and aftermath, I'd say it's quite reasonable to use an absurd number from one of the physicists involved.

Perhaps it was indeed wrong, but it sounds like that might be actually what those involved believed at the time.

3JPLW··on Scene report from the Chernobyl Zone
Estimates seem to vary wildly — which makes sense given the variety of agents and agendas. It's not really fair to hammer him on facts without acknowledging that the ground truth is far from certain.

Heck, even your fourth citation writes:

> Figures for the number of liquidators involved vary greatly from several hundred thousand to nearly a million people. It is likely that at least 300,000 – 350,000 people were directly involved. A report by the Nuclear Energy Agency quotes a figure “up to 800,000”. The International Conference “One Decade After Chernobyl” refers to “about 200,000 ‘liquidators’ who worked in Chernobyl during the period 1986-1987 and estimating the total number of people registered as involved in activities relating to alleviating the consequences of the accident at between 600,000 to 800,000.

3JPLW··on Ask HN: How close together are your bus stops?
Wow, that's almost exactly what I would have guessed. The block distance in Chicago is 1/8th mile (200m).
3JPLW··on Ask HN: How close together are your bus stops?
In US cities, the densest lines will have one stop per "block" — and that's frequently a regular tenth or eighth of a mile (and more regular as you move towards the newer cities in the west). So you'll typically find minimum distances of 160m or 200m and then multiples of those for express lines or less dense areas.

3JPLW··on What is a fork, and how GitHub changed its meaning
Yes, I've done this myself — it's just an email and they "disconnected" the fork within an hour. Very happily and friendlily, too.

Is it as easy to export tickets from Sourcehut? Can I participate in tickets on Sourcehut without creating an account?
3JPLW··on What is a fork, and how GitHub changed its meaning
I still respectfully disagree. If GitHub really wanted to deceitfully name this feature to foster the cathedral model they would have gone with "branch" instead. In fact, I recall them getting quite a bit of push back for naming it "fork" because it has historically been a pejorative term. Even further, I believe the actual operation is implemented as a branch on their backend for efficiency's sake. So why go so far as to call it a fork?

Well, because you can treat it as a fully maintained source tree itself (and participating like a member in a bazaar). It's easy to turn on issues locally, add collaborators, accept pull requests, and trade commits back and forth between the forks. Now, yes, GitHub does by default "link" it to the upstream repository and it even keeps tabs on how its history differs, but I'd call these features that reflect real use-cases.

Also amusing is how the repositories on kernel.org describe themselves; 149 use the word "fork". Sure, it's probably partly due to how GitHub uses this terminology, but I'd say it's a good thing that forking is no longer pejorative by default — now it's a "hard fork" that's a bad thing.

3JPLW··on What is a fork, and how GitHub changed its meaning
Yes, I did read that. But what is Linus' branch then, and why do folks aim to "upstream" changes to it?

I'd argue that the other important Linux sources are _themselves_ cathedrals, each with their own form of centralized leadership — be it an individual or a group (like a distro or company). And these cathedrals happily work together.

You can totally have this model with GitHub.

3JPLW··on What is a fork, and how GitHub changed its meaning
It's a little funny to focus on GitHub's fork/pull-request model if you're trying to critique their centralization and lock-in. Every single successful open source project — on GitHub or not — has a canonical "source" branch and some sort of organization/leadership that decides what goes in. I'd argue that GitHub's behavior here isn't a power grab so much as a reflection of reality.

The "real" lock-in is with the discussion model — on both issues and pull requests — and the organizational structure you're able to set up. It's easy to move the source code to another service. Heck, you can even email patches to maintainers of a project on GitHub without creating an account. It's not easy to move historical discussions/reviews or "commit bits"/maintainership roles, and of course you can't participate in reviews of an emailed patch that a maintainer PRs for you unless you create an account.

Amusingly the drama continued with a new post:

> censoring my comment will not resolve the inherent dishonesty of this article!!!

Even more amusingly, the commenter's name links to disney.com. Or perhaps it is a strange new astroturfing campaign.

3JPLW··on Europe says 737 Max won't fly until it completes it own design review
Absolutely 100% agreed. I started with that assumption and figured that even with very conservative numbers I'd be well below the number of driving fatalities. I did that calculation as I wrote that comment and didn't retroactively edit my initial reactions or change any numbers to fit my bias.

I'd love to see someone figure out the real numbers here.

3JPLW··on Europe says 737 Max won't fly until it completes it own design review
> I bet if you do the numbers it is the most dangerous way of traveling

That's just crazy talk. If it's more dangerous than a car I'll eat my hat.

According to NYT/Flightaware, there were ~8600 737Max flights per week. Let's call it 8000, and limit our analysis to the past year. Let's also make the very low assumption there are only 100 passengers on each.

8000 * 100 * 50 is very conservative 40 million passenger trips per year. And there were 350 deaths.

Cars have a fatality rate of ~1 per 100 million miles. That means that the average distance traveled needs to be ~1000 miles to be better than cars.

I challenge you to find better numbers estimates, but my very conservative numbers says they're on par or better than cars. I must confess I'm a little surprised how close it was.

3JPLW··on U.S. records 75 new measles cases, 9.8% increase, as outbreak grows
It is, as with many things, a mix of all things. But the decrease in vaccination rates is _definitely_ a huge contributing factor in many of the outbreaks. See, e.g.,

3JPLW··on U.S. records 75 new measles cases, 9.8% increase, as outbreak grows
Yeah, I've looked into the six-month option. At least some of those failures are thought to be due to Mom's antibodies — through breastfeeding — fighting the vaccine. So that's also a little bit of solace; we're not totally unprotected as long as she's breastfeeding.

We're also not in a hotbed, but it's really crazy how contagious measles is.

This is terrifying as a parent of an unvaccinated child.

She'll get her vaccine as soon as she can (starting at the 1 year checkup), but there are others out there that cannot get the vaccine for other medical reasons.

3JPLW··on Insurers Know How Often American Drivers Touch Their Phones
I was bumped by a car behind me in the exact same situation. I looked in my rearview mirror and immediately saw the cell phone in her hand. What made this particularly amusing was when we got out of our cars to assess any potential damage, I realized the woman only had one arm. Fortunately there was no damage — especially since I was in a rental car and wasn't looking forward to the insurance rigamarole.

I am now similarly cautious about such "false starts" — I try not to start rolling until I think I'll be able to continue smoothly accelerating to normal speeds.

3JPLW··on Insurers Know How Often American Drivers Touch Their Phones
While I believe that is technically illegal in many jurisdictions, I agree a quick peek is fine.

What I routinely see, though, is folks with their heads solidly down and noses buried in their phone. Just in the past week I've seen two folks _watching video_ on their phones while I was bike commuting. This is terrifying.

And sure, not everyone peeking at their phones at full stops will also be looking while they're moving. But folks who look at their phones while moving will definitely be looking at full stops, too.

3JPLW··on Insurers Know How Often American Drivers Touch Their Phones
That definitely won't work — my wife is in charge of my phone while I drive. This includes texting, GPS, and more.

Even if you knew I was the one driving, just looking to see that my phone was in use wouldn't be accurate.
