If they had ultra-wideband transceivers on each vehicle, wouldn’t that let them determine direction and location down to maybe (i’m guessing) 10 cm?

If all cars could detect these kinds of beacons, i’d want a transmitter on my bicycle. Or, carry one (my iPhone?) as a pedestrian.

DSRC and cellular-V2V i think solve similar problems, but those two require the more inaccurate GPS, i think,.

Still, I’d rather see empty Waymos bumbling around a parking lot than seeing empty Waymos clogging up our SF streets, and (observed twice recently) blocking pedestrian crosswalks.

Still, I wish Waymo had at fielded a vehicle smaller than an enormous, 5,000 lb, 400 hp Jaguar i-Pace SUV. That Jag is designed for 80-90 mph freeway cruising, not 15-30 mph urban driving.

I’m a little concerned the turbocharged engine are built to run just a little too close to the edge.

Sad to see, as the GT Corolla will soon have an optional automatic transmission. That, and 4 doors, make it a barely acceptable family car.

Check your owners manual to see if this type of data collection can be disabled. For our 2021 Mazda, it required a phone call to Mazda.

For real security, I’d like to pull the modem fuse, but i know neither which fuse to pull, nor if other systems might stop working.

The average person has the same recourse to a cop’s injustice as the average slave had to a slave catcher.

> Covered with burns, the truck driver walked nearly a mile along the freeway before reaching a gas station and getting into a cab.

A gasoline truck, surely going too fast, hit a freeway hazard in Oakland and burnt up the road while, ironically, on its way to deliver gasoline to a service station.

Going fast, as everyone knows, usually saves time, but sometimes can have disastrous side effects.

Should first blame for the crash go to the Caltrans road engineers?

> Hardliners have grown worried that the experiment with capitalism could threaten the government’s tight grip on power, and the Cuban military, which used to control most foreign currency coming into the island, is viewing these companies as competition, sources in Cuba said.

How much blame does the military have for the mass exodus of Cubans?

And if I’m reading the Orbital Tonnage chart right, then 80-90% of every ton now being launched is a Starlink satellites.

Maybe the biggest hurdle for everyone except Starlink (with their standardized design) is spacecraft design and engineering, not cost to orbit?

And SpaceX’s Starship will be able to put a payload of 150 tons into LEO. How could we possibly make use of that capacity, other than Elon’s idea of sending millions of people to Mars?

“ The lowest rate of long Covid in the study, 3.5 percent, was among vaccinated people who were infected during the latest period in the study, between mid-December 2021 and January 2022. That compares with a rate of 7.8 percent for unvaccinated patients in the study who were infected during the same period.”

I recall the incredible relief I felt after getting my first vaccine shot.

And I actually feel sorry for the vaccine refuseniks who never got that sense of relief.

The mass hysteria churned up by the anti-vax movement, and the amount of suffering it caused, is going to keep historians busy for a long time.

The data comes from the Polaris hotline.

Criticism from the Polaris wiki page:

“Reason magazine editor Elizabeth Nolan Brown referred to Polaris as "one of the biggest purveyors of bad statistics dressed up as 'human trafficking awareness'".”

In my 50s, I started drinking coffee in the afternoon. It helped a bit.

And Elon Musk would improve on these 5,000 lb Waymo SUVs carrying 1-2 passengers in favor of 7,000 lb Cybertrucks carrying 1-2 passengers.

The improved 0-60 times alone will prove Elon the more effective accellerationist.

“Social scientists have shown — for as long as we have been collecting data — that conservatives have better mental health than liberals, and religious people have better mental health than their secular peers.”

My gut tells me social scientists have “shown” no such thing, but am open to hearing the case.

Notable to me is it uses Java’s nee vector API: https://openjdk.org/jeps/469

OT: carbuzz.com estimated its curb weight as about 5,500 lbs.

That’s good when you’re driving 80mph on the freeway, but way too big around town.

I’d like to see drivers in US cities have the option for something smaller, like Renault’s new Duo, the replacement for the Twizy:

“running quantum chemistry computations on the inputs provided by the Georgia Tech team. These calculations used about 400 million CPU hours”

Not sure bragging about high energy consumption helps their argument as much as they think.

I think MITRE did a very good job in writing up the details here. If I were a system or security engineer, these seem to be immediate actionable items laid out for me.

Such transparency should serve as a model.

From 2004.

Anything new on this since?

He emailed the evidence to the police:

“Waite emailed his recording of the call to the sheriff's office records department and requested an internal investigation. A month later, Waite was accused of five counts of illegal wiretapping for recording the conversation with the sergeant and four other calls with sheriff’s employees.“

Or step-grandparent.

Thus sparking the engineer’s natural distrust of authority figures.

No, groundwater is renewable in a lot of places, like in much if the Sacramento Valley, where it rain 20-30” a year.

But in the Fresno/Bakersfield area of California, with only 5-10” if rain per year, over pumping is making farming uneconomic. See SGMA https://en.wikipedia.org/wiki/Sustainable_Groundwater_Manage...

I don’t think solar powered irrigation is practical.

To water 10 acres of orchard in northern California, where our water levels are “good” (wells are 100-150 ft deep), we need about a 25 hp (20 kW) well pump. That’s ~2 kW per acre.

A typical irrigation cycle is on the order of 10-20 hours. So budget about 20-40 kWh/acre for a cycle, and repeat every 10 days or so (crops need to dry out between waterings else disease spreads.)

In theory, a kW of solar panels charging a 20 kWh battery for 10 days should work to water 1 acre for an entire summer season, at a capital cost of a wildly uneconomic cost of perhaps $20,000 per acre.

These are my wild guesstimates informed by some orchard experience, but please correct me if my numbers seem badly amiss.

ps: With PG&E power, we currently pay about $400/acre, per year.

cat should be the command you learn second, after ls, because you need to know what you’re dealing with.

Mazda CX-30 has buttons.

As do Subaru BRZ/Toyota 86/Toyota GR86.

btw, I'm just throwing out that "Sign in with Apple" is "best" only to challenge "Sign in with Facebook" or "Sign in with Google" folks to explain why not.

At the very least, it's nice to have Apple whip up a random email address for you every time a site asks for one.

" Once, Underhill says, there was so much water that a steamship could carry "agricultural supplies from the Bakersfield area up to Fresno and then up to San Francisco" — a distance of nearly 300 miles. "

It'd be nice to re-establish a small channel, only open in big years, like it used to be.

For a straight male, you’ll see a surprisingly large number of fake profiles. Anecdotally, women seem to report this too. (Reddit has MANY such posts!) So identity verification is a real problem.

As an iPhone user, I’d seriously consider using a dating app that ONLY allowed you to “Sign in with Apple”, in the belief that it’s the “best” way to ensure a real human is behind the sign-in, more-so than email/pwd, or even Facebook or Google sign-ins.

Except maybe ID.me as used by the IRS and the VA?

Reminds me of my one devious professional hack.

Back in the 1990s I supported a website whose users were all in our local business group. It was mostly html tables, with black text on a jarringly bright yellow background.

Asked my users if I could change it to something more subdued. All said “good idea” except for one adamantly stubborn person who threatened much commotion if anything changed.

So, every week or two I slightly tweaked the background color such that each week’s change wasn’t really noticeable.

After 6 months the brightness was exactly where I wanted it to be, and the stubborn user was none the wiser.
