PorterDuff··on China Drone Attack on Crop-Eating ‘Monster’ Shows 98% Kill Rate
Perhaps most of the product is a refueling station.
PorterDuff··on Off-Grid, Solar-Powered, Zero-Battery Refrigerator
It would be interesting to know how much of refrigerator power consumption is due to door opening/insertion of warm food and how much is imperfect insulation.

Given that the writer of the article doesn't appear to have space issues, it would be cool to see a homebuilt unit with much higher insulation using an existing freezer to mine for parts. I really like the redneck Yeti coolers that people build.

A more trivial modification might be to put strips of plastic across the opening so that less air interchange occurs when you put stuff in or out.

PorterDuff··on A Gambler Who Cracked the Horse-Racing Code (2018)
They play in teams.
PorterDuff··on Depression, anxiety rising among U.S. college students
"I think a huge part of it is that getting a “good” job out of college has never been more competitive and more important."

That's an interesting point as opposed to the over-observed fragility of modern college students.

There's probably something to be learned from the different school and employment bottlenecks in Japan.

PorterDuff··on Alan Turing to be the face of new £50 note
No offense to Obama, but I expect he'll be merely a Jeopardy question in 100 years. Memorable people tend to come from memorable times.
PorterDuff··on Alan Turing to be the face of new £50 note
'Being persecuted' strikes me as a crummy reason to put someone on currency, it's more a sign of the times than a sign of gravitas.
PorterDuff··on Let's build houses for people, not cars
I'd say that it isn't just a matter of comfort, but also one of personal security.

I'd be far more apt to take a local train in Tokyo or Switzerland than I would BART.

PorterDuff··on America has no use for hides, so leather prices plunge
So how come Lucchese boots are still so expensive?
PorterDuff··on A Trailblazing Plan to Fight California Wildfires
Dunno if appointing geniuses will work.

It seems to me that part of the problem is that the different parties involved have different needs and resources.

. Homeowners would like to not have their homes burn. They are on 30 yearish investment horizons but buy insurance a year at a time. They are a minority of homeowners in the state.

. Insurance companies want to make a profit but have little to do with forest management. Their only knob is your bill or a cancellation. They are in the position of a health insurance companies who can cancel a sick person's insurance at any time.

. The state .gov is only loosely related to the people, these are not elected officials running the show after all. The urban areas are in charge in any case, just keep the water flowing and the occasional state park for weekends.

. No doubt it's an interesting challenge to the feds, but the occasional town burning down is just a statistic.

. PG&E is not in the fire suppression business whenever possible, keeps costs down, went bankrupt anyway.

It's all at cross purposes.

PorterDuff··on Yes, I’m Feeling Bad About Climate Change. Let’s Discuss
Dunno why it's classist or racist. I'll put forth the proposition that there are too many people in the US.

Imagine the greenhouse load reduction from having half the population. It wouldn't surprise me if it's easier to push population growth down than it is to have good habits, especially after the low hanging fruit is plucked.

PorterDuff··on Cities Are Saying ‘No’ to 5G, Citing Health, Aesthetics, and FCC Bullying
Since I don't download uncompressed 4k video anymore, I'm personally getting practically all of the value of the internet (to me) from merely having a cheap cable connection at home. I've never been certain who 5g or fiber is really targeting. Amazon works fine, Netflix works fine, downloading an OS or language tool set isn't too heinous. High data speed to a phone is uninteresting, but YMMV. As usual, improvements become less useful on the margin.

The one use case I've run into might be robot cars, probably lower latency/higher bandwidth. I don't know enough about where the intelligence actually lives or how much in the way of inter-car communications is actually required though.

PorterDuff··on Yes, I’m Feeling Bad About Climate Change. Let’s Discuss
Exactly. Any time overpopulation isn't mentioned as a (or 'the') primary cause, my nictitating membranes close up and I lose interest in reading.
PorterDuff··on 15 states are trying to make the electoral college obselete
re: California

It's also worth considering the distortions that illegal aliens put on electoral college numbers.

PorterDuff··on Survival of the Richest (2018)
My guess is that the article is fiction, or a highly modified version of the truth to make some point.

It is interesting to think about societies that can handle strong shock. Looking back, my guess is that the modern West doesn't have that capability built in. A proven model is one of a very strong hierarchy (monarchy perhaps) with strong social glue.

That isn't to say that you shouldn't go on extended vacation at your estate in Spain when a slave rebellion starts up near your place in Capua.

PorterDuff··on What It Takes to Hire 10 Employees in San Francisco
If I was 30+ years younger, I would consider that.

One problem is being old school enough that it's darned difficult to work for free.

PorterDuff··on What It Takes to Hire 10 Employees in San Francisco
I think I'd be happy to work on something interesting for crummy money. The trick is the interesting part.
PorterDuff··on Wavelets (1994) [pdf]
ImMix Cube products maybe? My memory fades.
PorterDuff··on The Sinister Brutalism of Shipping Container Architecture
Exactly. There was a Kirsten Dirksen video showing some cabins built on a piece of property that was zoned (I think) for mobile homes. Voila', they welded some big wheels on the bottom of the structures.

They still seemed poorly laid out with crummy bathrooms (in this case, no piped water and a terlet that was basically an indoor plastic porta-potty) but I did admire the law-skirting.

There can also be avoidance of property taxes in some states I believe.

PorterDuff··on The Sinister Brutalism of Shipping Container Architecture
If it's the house I was watching, the amount of house infrastructure within the house cracked me up. A house in a house, full slab, plus the inevitable California fire suppression system. It wasn't even that cool looking.

But...I really liked the idea of the above ground septic drain field.

PorterDuff··on Motion smoothing is ruining cinema
I take it that you aren't a fan of pan and scan.
PorterDuff··on Motion smoothing is ruining cinema
Just as an aside, there was a lot of work on this kind of thing (ie. 'improving' 3:2 pulldown) before the modern flat panel tv. Improving slow motion sucked up a few kilobucks of engineering time.

Also consider that a film is watched in a different environment and lighting than a TV.
PorterDuff··on Insured price $2,758, cash price $521
I would prefer a system where they charge everyone the same amount. It wouldn't surprise me if the insurance companies would be in favor of that, the whole price negotiation overhead goes out the window.
PorterDuff··on Insured price $2,758, cash price $521
Dunno if that's strictly true.

A story. Emergency room visit for moi (super high BP plus PVC that appeared out of nowhere). They hook up an EKG machine, wait an hour, tell me to see my doctor. Since it was a heart thing, I got bumped to the head of the line but forget to fork over my insurance card.

Bill #1 $10k from hospital $2.5k from ER physician

Bill #2 $4k if I pay it right away in cash

Bill #3 $500 (deductible cost) once the insurance people are brought into the picture.

PorterDuff··on Standard Ebooks: Free public-domain ebooks, carefully produced
This is a great idea.

Another ebook non-profit I'd like to see is one that shepherds books through the copyright maze. No doubt there are scads of books in the public domain that no one has proven are actually there. Perhaps this exists already but it strikes me as a good separate, and highly targeted, kind of effort.

PorterDuff··on Living Near Trees, Not Just Green Space, Improves Wellbeing
I think of high contrast areas as having the strongest mood boosting. By that I mean river fronts, visible mountain ranges, the beach, the edges of forests. No doubt trees in cities are visually pleasing, living in the middle of dark dense forest not so much.

'round these parts, trees seem to perform two useful functions. They fall on houses during storms (quite common) or they burn down whole towns. Be careful what you wish for.

PorterDuff··on Programmers: Before you turn 40, get a plan B (2009)
The endgame is likely flintknapping, although I was tempted to re-create Egyptian fiaence as an Etsy business.

(reading through the referenced story, it parses like RA Lafferty. I would pay good money for a conversational Alexa of that type)

PorterDuff··on Programmers: Before you turn 40, get a plan B (2009)
That's a good post, but I think that I went down a different set of windy little paths. My worlds (graphics and video products) had tons of companies disappear, and the ones still standing matured to the point of offshore manufacture, maintenance, decreasing margins. It hasn't all disappeared but I think that a lot of the fun is gone.

I'm older than you, never bothered with internet technologies and languages, and feel a bit of ennui about the whole deal. My guess is that a world that only consisted of workstation software and embedded systems, slightly fleshed out with an internet made up of Amazon, email, USENET (and cars without video games on the dash) is just the fantasy of a Luddite.

My temptation is to take on increasingly archaic skills. Rebuilding a carburetor or playing a musical instrument is already in the pallet, so maybe bookbinding or blacksmithing should be on the horizon.

PorterDuff··on Sony's mini air conditioner can fit in your pocket
Not everyone spends 24/7 in a conditioned environment. There's a world beyond the keyboard.
PorterDuff··on The Water Wars of Arizona (2018)
From the title, I thought it was going to be about Tombstone vs. the Forest Service.
