dmckeon··on How the design of a WWII plane led to the concept of user friendliness (2019)
A similar confusion may be audible in any McDonalds. Their kitchens have many alerts and alarms, and many of them use the same tone. Get a beverage, stand with a view behind the counter toward the kitchen, wait, and listen.
dmckeon··on Complete Guide to Buying Lumber (2015)
> their framing lumber quality is really poor

For 1x and 2x softwood at big box stores, assume that the 10% of pieces that are the most accessible have been picked over and rejected by previous customers. If you just need strength, take almost anything, but if you want nicer-looking boards, be as picky as those who shopped before you.

dmckeon··on Health Insurance Shouldn't Be Tied to Employers
The impact to labor mobility is significant: people who rely on employer-provided health care would be more reluctant to change jobs if there is any risk of discontinuity of health care for chronic conditions, or a higher cost for any conditions pre-existing before the new job starts. The US has not had indenture by name for decades, but we still have it via health care.
dmckeon··on After many false starts, hydrogen power might now bear fruit
With regard to https://pbs.twimg.com/media/DPkaz0nX4AAcr_v.jpg if the capture and separate elements can be decentralized, then distribution and one storage phase are eliminated.

In other words, if a refueling station can do solar or wind capture and electrolysis on-site, the economics are better. This would be unlikely for stations in urban or high-density areas, but for rural and suburban locations it might be a win.

dmckeon··on Derailing illusions that kill: misperceptions at railway crossings (2003)
> the traditional American crossbuck, the simple X-shaped railroad sign that warns drivers to yield to an oncoming train.

I would guess that roadway signage in the US runs about 80:20 textual:symbolic, but that the EU runs about 20:80, with much heavier use of symbols, and use of text only to modify or explain something not covered by the available symbolic palette. Could any EU->US or US->EU migratory drivers make their own estimates?

dmckeon··on A 1950s proposal to nuke Alaska (2015)
Some of those investigations were more than theoretical, as the Jicarilla Apache well know: https://en.wikipedia.org/wiki/Project_Gasbuggy
dmckeon··on The caretakers of Sealand, the most stubborn micronation
If you fly on British Airways, their passenger identity page has a menu that includes titles: Lord, Lady, Dame, etc. Of course, you must use this power for good ...

dmckeon··on Sergey Brin has a secret disaster relief charity
As a thought experiment, imagine some wealthy private citizen who could afford to spend, say, $10 million USD and had a few hundred employees to draw a team from, and adequate transportation to a disaster location.

Now identify a country that could respond with a similar level of aid in less time. Not more aid in more time, but just “beat to the punch” with a useful initial response. Citations preferred.

dmckeon··on Realtime Starlink Satellite Map
Fewer potential users in the near-polar regions, so the orbits are angled & aligned like wrapping a ball of twine, while polar coverage would require multiple tracks in north-south orbits.

dmckeon··on Twitter, Reddit support challenge of visa applicant social media requirement
Defendants in US federal courts plead guilty in about 90% of cases: https://www.pewresearch.org/fact-tank/2019/06/11/only-2-of-f...

Whether that is due to “very good reasons” or the possibility that prosecutors have many options of how many charges to bring and what degree of charge is debatable.

dmckeon··on Supreme Court says state may enforce some restrictions on religious gatherings [pdf]
Because in the US, states get to make some rules, and the federal government gets to make some other rules, and each is protective of their rights and prerogatives as enumerated in the US constitution, as amended. Look into amendments 9, 10, 13, & 14 for more.

When the US federal government has wanted to enforce things like a nation-wide speed limit, or vehicle safety requirements, they have had to threaten to withhold highway funding to get states to go along by passing state-by-state laws. In theory, the same could be done with helmet laws, but enough political energy has not materialized for that to happen. This pattern will have implications for full-self-driving vehicles.

dmckeon··on Pulmonary Vascular Endothelialitis, Thrombosis, and Angiogenesis in Covid-19
Also at: https://elemental.medium.com/coronavirus-may-be-a-blood-vess...

Briefly, previous SARS viruses reproduced in the lungs, impairing respiration, but Covid-19 reproduces in the cells lining blood vessels, impairing circulation.

dmckeon··on History of Unix Manpages (2011)
Changing all existing man pages (in all distorts, languages, etc.) seems like a “boil the ocean” solution - perhaps easy on the technical side to automate conversion of 1000s of pages, but harder on the social side of persuading most distros to use a new format.

A tool or family of tools that convert various other formats to the groff format might be a more accessible project.

dmckeon··on Herd of Fuzzy Green 'Glacier Mice' Baffles Scientists
The curved upper/exposed surface could act as an airfoil, allowing gusts of wind to lift the moss-mouse, and move it a bit, and/or rotate it around it’s vertical axis.
dmckeon··on Herd of Fuzzy Green 'Glacier Mice' Baffles Scientists
I believe they may have grown out of “terms of venery” or words specific to hunting - an activity often divided into class-specific groupings.
dmckeon··on Just Room Enough Island
From the title, I was expecting https://en.wikipedia.org/wiki/Stand_on_Zanzibar (title from a mention in the novel of a factoid that the entire human race, standing close together, would just cover Zanzibar.

Would love to see either this or Brunner’s https://en.wikipedia.org/wiki/The_Shockwave_Rider as well-produced films.

dmckeon··on Ask HN: Do you ever go back and admire a piece of code you wrote?
I’ve heard that styled as “do project the document, don’t document the project” but I don’t know a source to attribute this to.

The idea is to write a rough draft that covers what the project is, what it does, the API structure, and how to use the project, then write the code, “projecting the document”, and finally sort out the documentation - comments in the source, everything else in a manual page, article, or research paper.

dmckeon··on The Cost of Free Doughnuts: 70 Years of Regret
One wonders what the alternative-history narrative would be if the US had offered to pay the Brits for their soldiers’ snacks? Perhaps the common UK complaint about US soldiers in WWII would have been: overpaid, oversexed, overweight, and over here. :-)

dmckeon··on The SEC Rule That Destroyed the Universe
The core issue seems to be that executives who are effectively “paid in stock” are directly incentivized to maximize the market value of the stock before they sell, whether that is good for the long-term health of the company or its other shareholders, or not.
dmckeon··on The 1k-Bed Comfort Was Supposed to Aid New York. It Has 20 Patients
We should not be surprised - this is what Puerto Rico saw after Maria:

https://www.nytimes.com/2017/12/06/us/puerto-rico-hurricane-...

> The ship was prepared to support 250 hospital beds, but over its 53-day deployment, which included travel to and from the island, it admitted an average of only six patients a day, or 290 in total. An additional 1,625 people were treated aboard the ship as outpatients, all at no cost.

dmckeon··on Ask HN: How are you managing your money now?
Eventually, yes. Meanwhile, FUD will rule, GDP will be depressed, markets will be frothy, and the service economy will be in freeze-frame for as long as social distancing is generally expected. Any person or business with limited cash on hand or in dependable income streams faces a long passage.
dmckeon··on Tree felling work uncovers WW2 underground bunker near Moffat
Near the town of Moffat, in Scotland, not Moffat Federal Airfield (Naval Air Station) in Sunnyvale, CA.

For commercial trucks, there is a law - search “Mansfield bar” or (possibly NSFW image) https://sparebumper.com/the-mansfield-bar-jayne-mansfield-an...
dmckeon··on The easterner goes west in three early American comics
No mention of the risk of malaria on the Panama route? Perhaps alligators were more dramatic and better suited to the graphic medium.
dmckeon··on Bubonic Plague Strikes in Mongolia: Why Is It Still a Threat? (2019)
The plague is endemic in fleas on rodents and small wild animals in the US Southwest. Most people who contract it are first treated with antibiotics after presenting with the typical symptoms, and only a few days later do the test results confirm the presumed diagnosis.

The riskiest situation is exposure to plague and then quickly traveling to some other location where plague is rarely seen, and doctors at the destination do not know to look at the symptoms as possibly plague, and to tentatively treat for plague before testing confirms the diagnosis. Medical groups in New Mexico have several time done public awareness programs using the tag line: “Land of the flea, home of the plague.”
