dwd··on Kirkland Roundabouts
> Single-lane roundabouts are really straightforward

Like the Arc de Triomphe roundabout? :)

If it had lane marking there would apparently be 10 tracks around the circle.

What makes it seem crazy is cars entering have right of way.

The reason it works seems to be French attitude. Cars entering do their thing, and cars already going around do their thing (and just have to avoid anyone on their right).

dwd··on The Magic Roundabout of Seattle Area
Probably an instance where busses need their own level/ramps.
dwd··on Kirkland Roundabouts
That is a very basic roundabout. I was expecting by "magic" that you would have to go round some part in reverse (clockwise for US left-hand driving). This is nothing compared to the original "magic" roundabout of Swindon, Wiltshire.

This interchange might have been better off using a diverging diamond interchange layout [1]. While not a roundabout they are "magic" and we should use them more often.

They just look confusing because at some point you are effectively driving on the wrong side of the road, but are extremely efficient. My daily commute includes one that cuts a few minutes off what it once took to negotiate the previous traditional interchange.

dwd··on A short history of Cerro Torre, the most controversial mountain (2012)
It's about leaving it in the state you would like to have found it. No rubbish, no abandoned equipment, no bouldering-style puzzles already solved because someone has stuck a bolt there.

I do wonder whether the boulderers find it annoying when a boulder is clearly already solved by the worn, chalk marked hand holds. Probably explains why many seek out new untouched sites to solve first.

There is the "Leave No Trace" principle where you do not leave anything behind.

This is why you see in trad climbing the lead will place cams and nuts, while the last in the group on that pitch retrieves them.

dwd··on Firewood Splitting Simulator
Used to watch the competitive wood chopping at my local agricultural show all the time.

The highlight was always the tree felling competition. Each competitor has an axe and four springer boards, and it's a race to basically chop the top off a standing telegraph pole.

That would make a better game.

dwd··on If you are asking for human attention, demonstrate human effort
And no one has mentioned Rovo yet.

Atlassian's in-built AI assistant for JIRA will generate a task description with a complete SDLC task breakdown, requirements and deliverables.

While the person creating the task will need to provide some details and modify some of the generated text (if they bother to read it) - the sheer verbosity and the fact it's clearly generated just makes you not want to engage with it.

Or the Russian POM-3, scattered by aerial deployment, detects vibrations before bounding and detonating in the air.

dwd··on What is it like to be a bat? (1974) [pdf]
For a non-bat to experience what it is like to be a bat, you have to embrace one of two philosophies: - Dualism: body and soul/consciousness are separate), or - Panpsychism: consciousness is fundamental and doesn't emerge from the material physiology.

For a materialist, and someone who thinks consciousness arises from the physical aspects, the idea of a human experiencing bat consciousness is not possible. Our evolution developed algorithm for processing the world is wired to our senses. Similarly a bat's perception of the world has evolved along with bat senses and is not the same as ours.

Without any of the evolutionary pre-wiring, a human conscious dropped into a bat would be deaf, dumb and blind.

dwd··on Rich Sutton on AI creativity and discovery
Sure, but does that mean he's right all the time about all things, including everything in his own field?

He is saying no generative AI is going to produce output that is both good and novel because it is always derivative. And then adds a generative AI (Claude Code) into his list of AI that have produced output that he feels is good and novel, invalidating what he is arguing.

"...no matter how many instances of white swans we may have observed, this does not justify the conclusion that all swans are white."

dwd··on Rich Sutton on AI creativity and discovery
"We have many AI systems which can give us more. ... and Claude-Code, which have brought true advances in science, mathematics, and programming."

That contradiction kind of says he doesn't know what he's talking about.

dwd··on Forever Young: how one molecule can lock plants in a youthful state (2025)
Problem is, most of these "coastal" acacias don't live very long. Same with grevilleas.

The ones we have planted in our garden will likely need replacing in 7-15 years.

dwd··on Mornings and nights no longer exist at 47C: A day in the hottest place in India
As a child traveling around northern Spain and rural southern France we got caught out and had to stop and wait for a service station to reopen so we could buy petrol. All part of the experience.

I've lived in a few places that would get consecutive 40C+ days. Perfectly fine unless the wind is a strong northerly blowing from the interior. The 37C in Brisbane this year was much less bearable due to the higher humidity: 75% rather than 45%.

What I find bizarre is the word "siesta" doesn't appear in this article.

People have been working around the hot summer hours in Southern Europe for centuries. Until recent times it was part of the culture.

I would also add Iain McGilchrist, Donald Hoffman, Andy Clark, Jeff Hawkins and Jesse Prinz to that list.
dwd··on Squillions: How money laundering won
I always thought the TV show Ozark was fairly accurate in it's depiction of money laundering. The family would buy a small business that they could inject cash and cook the books with fake sales.
dwd··on Claude Opus 4.8
Can we just say it was basically vibe coded, but with real humans in the loop?

Version 5 was when the source material dried up, and the hallucinations became more frequent and obvious.

As far as I remember there was a basic outline of major plot points and where all the major characters ended up (a prompt) and were left to fill in all the blanks.

Given he posted this comic in 2008, Randall Munroe was way ahead of the ball on the idea of autonomous agents.

Maynard Keynes posited a future 15 hour work week in 1930 based on the productivity gains after WW1, nearly 100 years ago now.

dwd··on Does anybody like React?
Back in the days when launching a website was an event, and sometimes included junket trips to attend.
dwd··on The real cost of owning a home
It depends. If you own a single block dwelling and have a yard with trees, plants, lawns or a pool there are always things to do.

$500/year for the garden is very conservative, even when you're doing all the labour.

It would be more like $500/month were you to get a gardener in. If you need an arborist (for example cutting back tall trees close to power lines or encroaching on neighbours) it gets expensive very fast.

A pool also costs at least $500/year just in chemicals.

dwd··on Is "colorectal cancer" rising in "young people"?
"Other products" is quite a long list, though there's more a link between a high intake of refined sugars that promote particular bacteria that can damage the lining. Still often the same products to avoid or minimise.

We've been on the whole food path for a few years now, and while there's a bit of extra time in prepping all the ingredients from scratch and you have to turn over fresh vegetables often (therefore more frequent visits to the market) you at least know what you're eating.

dwd··on Taking a walk may lead to more creativity than sitting, study finds (2014)
Always wonder whether this fits with Jeff Hawkin's "Reference Frames" where he ties movement to learning and understanding - and I would also say creativity.
dwd··on Does anybody like React?
React was a major improvement over Backbone + Marionette. Pre-jQuery was a shit-show as they hadn't even standardised the DOM.

Before that was XMLHttpRequest (particularly during my .Net WebForm days) and even had to use the ActiveXObject in IE that predated JSON.

Groupon? Did an IPO with a 12.7b valuation and was mostly dead within a year.
dwd··on The Eternal Sloptember
Joined Usenet in 1990 and for a few years it was great.

I always wonder whether HN suffers from periodic influxes of newbies who don't get it yet and rile up the regulars.

Isn't this Sun YuChen, who has been dogged by crypto scam accusations for years?

dwd··on The Worlds Left to Conquer
They're often polymaths - generalists who are very competent across the fields they touch on but not necessarily the best. It is their ability to reach across multiple fields simultaneously or bring together experts in those fields that you see great things occur.
