sonofgod··on Just Room Enough Island
They're around 250 metres from each other.

The Thousand Islands seems a completely ludicrous place that feels like a fantasy novel. Or Legend of Zelda: Wind Waker

sonofgod··on The Cannonball Run record has been broken seven times in five weeks
These new records are likely to be unbeatable once traffic returns to normal. I wonder whether that'll cause the demise of the Cannonball Run?

That said, in computer speed runs, it's generally said that once someone says a run is unbeatable, it'll be beaten...

sonofgod··on Ignition: An Informal History of Liquid Rocket Propellants (1972) [pdf]
"hypergolic: igniting spontaneously on mixing with another substance."
sonofgod··on Ignition: An Informal History of Liquid Rocket Propellants (1972) [pdf]
On chlorine trifluoride:

”It is, of course, extremely toxic, but that’s the least of the problem. It is hypergolic with every known fuel, and so rapidly hypergolic that no ignition delay has ever been measured. It is also hypergolic with such things as cloth, wood, and test engineers, not to mention asbestos, sand, and water-with which it reacts explosively. It can be kept in some of the ordinary structural metals-steel, copper, aluminium, etc.-because of the formation of a thin film of insoluble metal fluoride which protects the bulk of the metal, just as the invisible coat of oxide on aluminium keeps it from burning up in the atmosphere. If, however, this coat is melted or scrubbed off, and has no chance to reform, the operator is confronted with the problem of coping with a metal-fluorine fire. For dealing with this situation, I have always recommended a good pair of running shoes.”

sonofgod··on Ignition: An Informal History of Liquid Rocket Propellants (1972) [pdf]
An absolute classic: people may not be aware it got reprinted, and is therefore available in dead-tree (and ebook) format again.
sonofgod··on Ask HN: I'm a software engineer diagnosed with Alzheimer's,how should I prepare?
Firstly, fuck. That sucks.

Here's my penny's worth, as someone with no actual experience of the disease:

From a programming and work perspective, make sure that other people have the knowledge and skills to take over. Little things that should be obvious (and ideally avoided up front), but only in hindsight, like write access to repos, third-party accounts linked to email addresses. Now is a good time to audit them.

And the bigger things, like "so how is this library Charlie wrote supposed to work?" Now might be a good time to pair with someone unfamiliar with it to make sure documentation is up-to-date and encompasses what the intention behind the decisions was.

Depending on what you're working on, there might be a point in the future at which you might be inadvertently capable of harm: accidently publishing secrets, etc. I don't know enough to know how best to mitigate this, or even if it needs worrying about at all in your work.

If you've got any projects that have downstream users, you might want someone else to also have write access to the project. Managing their expectations on the future may be of use to them.

Consider getting pictures/video of your favourite projects, people and places in the work environment; I've heard these sort of external memory cues can be helpful later on in sparking recall of memories.

Best of luck in what is going to be a trying time for you and your loved ones.

sonofgod··on Six Signs of Scientism (2009) [pdf]
One might as well complain that when that one kilogram pile of protons, neutrons and electrons flaps and squawks like a chicken, it no longer "follows science". It's just that biology is a better, higher level tool for getting meaningful than particle physics for explaining the trajectory of a chicken.

And it's a well-known aphorism that "in carefully controlled conditions ... the experimental animal will do as it damn well pleases". And yes; it becomes more difficult to reason about the trajectory of that chicken when its internal motivations and factors like hunger, tiredness etc. are opaque to us. And I think that's directly analogous -- DNA and the processes of life have programmed and reprogrammed matter, and does make reasoning about them harder.

And it highlights the importance of metaphorically aseptic technique in the analysis of malware and computer interaction; and in doing so highlights the problems of "laboratory conditions" being distinct from real world ones since malware might detect the abnormal sterility...

(I'm not even sure whether I'm agreeing with you or disagreeing. But your post was thoughtprovoking.)

sonofgod··on Now Is the Perfect Time to Memorize a Poem
If you're super short on time:

"Ode to a Goldfish", Ogden Nash.

Oh, wet pet

[my interpretation: to be declaimed grandly as a great epic, before tailing off as if you've forgotten]

sonofgod··on New Zealand PM: No open borders for 'a long time'
Did someone realise that one of the cases wasn't actually a case?
sonofgod··on New Zealand PM: No open borders for 'a long time'
The UK currently has nothing to fear from open borders: why worry about the risk of a planeload of cases when there's ten new planeloads* of homegrown coronavirus every day?

Everyone else, however, may well have something to fear from the UK...

* 747: 450 passengers; new cases 4400 (5 May)

sonofgod··on Nobel prize-winning scientist: the Covid-19 epidemic was never exponential
> if you have twice as long infectious and half the R 0 you'll get exactly the same growth rate (7m15)

uh... no. (I am not an epidemiologist, but neither is he, so...)

R is an estimate of the total infections one person will cause. So if you're infected for twice as long, and R remains the same, then the growth rate will be halved. If you also halve R, the growth rate will also be halved.

I don't believe he understands what he's talking about.

sonofgod··on Ask HN: OK to restart an app abandoned by it's founders?
Literally from googling, so not legal advice:

https://www.upcounsel.com/abandoned-trademark

A dead trademark is not always available for use or registration by someone else because the original registrant might still be using it, and thus retain common law trademark rights. Search the USPTO website to learn why the trademark was abandoned. You might be able to acquire the trademark depending on the circumstances of its abandonment.

Before using an abandoned trademark, speak to a trademark and branding attorney and find out why the application was abandoned.

You must clear the rights before using the mark.

If the mark has been abandoned for three to five years, most likely you're safe. But beware that a non-active mark in the USPTO database could still be in use by the original owner. Even if you prove that the original owner has no intention of using it again, you still risk legal problems.

Make sure to also check all countries where the mark was used.

sonofgod··on Shirt Without Stripes
My first assumption is [shirts -stripes]

Of the first ten hits: Amazon: 7/10 aren't shirts (but all are stripeless) Google: All shirts, one is checked Bing: All shirts, all contain stripes in description.

Not exactly glowing for Amazon, clearly unsupported by Bing.

sonofgod··on Show HN: Tom Nook's Laptop
I parsed it as AC, for Animal Crossing, the left part of the C being also the right leg of the A.
sonofgod··on Show HN: Tom Nook's Laptop
So it looks like they use ethernet and SD cards in the Animal Crossing universe too (right hand side) (the middle is probably USB but rectangles aren't very diagnostic)

And I think there's HDMI and a 3.5 mm headphone jack on the left? :P

sonofgod··on United Kingdom to introduce security labelling on connected devices
Trying to work out what I'd want in a first pass. At an absolute minimum:

* A commitment and ability to update any critical security issues for a specified amount of time

* Standardised mechanisms for reporting critical updates to users which are not used for marketing

* A basic checklist of best practice for internal self-audit (SQL injection, plaintext data, enumeration attacks)

A low bar, but still far better than what we've currently got. (External audits are probably silver tier?)

sonofgod··on Airlines flying empty planes to keep flight slots during coronavirus outbreak
I feel like there's a short-term solution to this:

You can keep your slot and not fly the plane, as long as you pay some large percentage* of the cost of each ghost trip to the organisation that'd resell your slot. Your 'flight' must be fully crewed.

That way the carbon isn't emitted, (some) jobs are kept secure, and the airline recoups a little of the money they would have otherwise lost.

sonofgod··on Command-line program to download videos from YouTube.com and other video sites
Top tip: it'll fairly regularly stop working, because Youtube have changed the website.

If you encounter this, there'll almost certainly be a new version which fixes the problem.

sonofgod··on Jitsi Meet: open-source video conferencing
Bear in mind that your URL is your password, and you might occasionally get randos joining you if it's too simple a URL. Happened to me once at work, got some giggling people whilst we were pairing, they then hung up immediately :)
sonofgod··on Freeman Dyson takes on the climate establishment (2009)
A model that can't predict inputs can provide a mapping from any given inputs to a predicted value. We can then, after the fact, demonstrate whether the actual value is equal to the predicted value (i.e. within expected error bars). Repeated failure to predict at the expected probability of your error bars would falsify the model. (i.e. commit to what your model is, then run it with now known inputs after the fact)

It's possible some of these inputs may be of the form "the Gulf Stream continues to operate within historically observed parameters", i.e. we make no attempt to claim accuracy for the model outside of its studied conditions. That's fine: there are a large number of accurate models which are known to have breakdown conditions.

It is literally impossible for any model to be robust to unknown unknowns. All we can do is endeavour to drag them into the light and become known unknowns, then attempt to quantify them as known knowns. Sadly, our ability to experiment repeatedly in the same conditions with the environment is deeply limited, in a way much akin to astronomy.

sonofgod··on 'This airplane is designed by clowns':Boeing employees KNEW about 737 Max issues
Just a heads up - the Daily Mail are not a reliable source of news. (for example: Wikipedia have had to ban them from citations due to "the Daily Mail’s reputation for poor fact checking, sensationalism and flat-out fabrication".)

Whilst this specific report is echoed in other news sources, and therefore probably accurate, I'd avoid using the Daily Mail as a primary source of information.

sonofgod··on More than 80% of total knee replacements can last for 25 years
The big thing to add to the cost of having a human-sourced knee is being on immunosuppressant drugs for the rest of your life, which is a significant health risk (but significantly less than, say, not having a functional critical organ). There are processes to clean some transplants, but I'm not certain they work on anything other than the simplest of structures (e.g. pig heart valves)

Corneas are the exception: they don't provoke an immune response.

sonofgod··on You can't just rename your IT Ops team and call it DevOps
I've had "here is an install of Jira, go play" with no configuration done or any admin existing too.

My greatest achievement in that job was making production a git repo so that we could regards against production before pushing. A sufficiently low bar you'll trip over it.
