y'know what's cooler than Perlin Noise? Simplex Noise [1]! This is what is hinted at at the end of this article. Also invented by the same person to address issues in the original Perlin Noise function. It's not as popularly known because it was restricted by patent issues for so long but as of 2022 the patent has expired!
the only thing I can imagine in the near-term are a subset of vehicles in the fleet which have carseats for infants and todlers which stay installed in the vehicle. We also already see vehicles from Volvo which have integrated/convertable booster seats for children 4+ and maybe the entire fleet could have these.
The global leader in self driving cars has a headquarters thirty miles from here - the city could invite someone from Waymo to give a talk on the future of onsite parking and how our codes should adapt.
I agree with pretty much everything in your article, Kevin. But I wonder whether Waymo actually has a holistic vision for how families would use their service? Do they expect people with small children to haul around a carseat or booster seat (possibly multiple) for these trips until all their kids are old enough? And spend the extra couple of minutes double parked while they install/remove it?
Michael Crosby wrote this! He's a long-time maintainer of Docker, Containerd, and more! He was Docker's first to receive the 'Distinguished Engineer' Title. This means a lot coming from him.
they specifically said "Splotlight Semantic Indexing" which means they generate embeddings of all your "personal context" and store it in a local vector database so they can do on-device RAG.
that's interesting because my understanding was that a lot of models used pressure as the vertical (height) coordinate and with tracking temperature at any given coordinate lets you know the density of the air at any point.
Atmospheric circulation. hadley cell, polar cell, and mid-latitude cells. It would also be interesting to see how new bands would occur if we increased the rotational speed of the earth, thus increasing the strength of the coriolis effect. It would also be neat to draw your own continents and orography and see how that impacts climate. which places become more wet/dry, etc. Change how much long wave radiation is absorbed by the atmosphere as the composition of the atmosphere changes. I'm not interested in actually making weather or climate predictions but using it as a tool to educate people on how the climate works.
The title should be updated to note this is from 2006.
Has there been anything like this published in the past 20 years but for compressible fluids? I have wanted to make a simple atmospheric model for years but have been unable to because of the complexity and probably my lack of complete understanding.
I was waiting for him to make some point but then it ended up being that a wealth tax is like increasing regular income taxes by 20% which makes it seem like PG is trying to confuse people about what a wealth tax is designed to target. It's not targeting your wages or salary, or even your interest or dividends. It's primarily targeting unrealized gains on financial securities.
Maybe he should spend his time trying to work with these politicians to design something that is more fair? Like making it actually act as a tax on unrealized gains over $1B (so that it takes cost basis into consideration) OR make it so that if you need to sell some assets to pay the tax, you can writeoff the wealth tax you paid from your regular/capital-gains income so that you aren't taxed twice? There's a lot of actually useful stuff he could write about in this policy area instead of blogging about the financial equivalence between stocks and flows.
Antigravity was the only autonomous agent that implemented the Pantheon’s signature interior ceiling pattern: repeated square coffers visible through the oculus.
That is seriously really impressive. I looked at the 3D model and didn't even thing to LOOK INSIDE the building before reading this.
Here's [1] the 3D model with `show_cutaway` enabled.

while I understand that we are computing the tokens in parallel to get the "faster" result, is there a tradeoff where we're actually utilizing more compute resources by running multiple instances of the large model? That is, while it's faster, is it more efficient?
edit: doing some more of my own research, it sounds like the bottleneck in doing it sequentially is in shifting weights around in memory, so while it uses more compute it doesn't oversubscribe compute resources because the bottleneck is not in supply of compute but in supply and speed of memory. The GPU has a massive supply of compute but sequential decoding only demands a relatively small amount of it. Time is primarily spent waiting on loading values from vram.
This seems hyperbolic as it's actually a long path between age verification to full digital identity tracking. But I agree that pushing the burden of verification to websites is ridiculous. Like the GDPR requirements where every webpage has an annoying consent modal, the verification and preferences should be controlled on the device you use to access these digital services. My browser should know and enforce my cookie preferences in a way that has a uniform user experience. Likewise, if I am a minor, my parent should provide me with a device (or profile on a device) which knows my age and can use that to inform online services of the age of the user rather than needing to go through a separate process for each service.
they are saying that LA takes water from sources which would otherwise drain into the sacramento and san joaquin river delta. The video from this post mentions the California State Water Project which takes water from the Feather River (Oroville Dam) and distributes it along the Western edge of the central valley South to Bakersfield where it is then pumped over the mountains both towards Los Angeles and further East to San Bernardino and Riverside. It provides way more water to SoCal than the two Los Angeles-specific aqueducts from the Owens Valley on the Eastern side of the Sierras.

It's incredibly suspect that in a battery capacity test ...
They would probably say this is because it's not a "battery capacity test" but a "charge performance test"
But I agree, when they eventually do have VTT perform a capacity test, how can we be sure that it's the same cell from the charge performance test?
control inflation
I think you are confusing cost inflation with an increase in the money supply. The way the US government funds deficit spending is not by increasing money supply (though it could) but by issuing debt in the form of US Treasury bonds. That is a transfer of money from bond investors to the government. No new money is made. This is distinct from the way that banks issue loans which is by creating new money in the form of credit (but that credit money gets "burned" as loan principal is paid back). So federal taxes do not actually control inflation in the way you are describing. Since federal deficit spending is not financed by increasing the money supply, it can only cause price inflation if it increases aggregate demand over the current productive capacity of the economy. An example would be paying more for healthcare subsidies when there's a shortage of doctors. Or subsidizing demand for housing with more mortgage subsidies when there's a housing shortage. Taxes could also increase inflation if they have the effect of reducing supply of some goods or services (like tariffs do).
Edit: I want to mention that the Federal Reserve can and does increase money supply by buying US Treasury Bonds from banks (converting the asset into cash reserves). There are various reasons why they do this but overall it's done with their dual mandate in mind: control inflation and minimize unemployment.
the world’s foremost real-time information and free speech platform
What a joke.
the book I mentioned (_The Experience Machine_ by Andy Clark) talks about this.
Now I can't stop thinking about _The Experience Machine_ by Andy Clark. It theorizes that this is how humans navigate and experience the real world: Our brains generate what we think the world around is like and our senses don't so much directly process visual information but instead act like a kind of loss function for our internal simulations. Then we use that error to update our internal model of the world.
In this view, we are essentially living inside a high-fidelity generative model. Our brains are constantly 'hallucinating' a predicted reality based on past experience and current goals. The data from our senses isn't the source of the image; it's the error signal used to calibrate that internal model. Much like Genie 3 uses latent actions and frames to predict the next state of a world, our brains use 'Active Inference' to minimize the gap between what we expect and what we experience.
It suggests that our sense of 'reality' isn't a direct recording of the world, but a highly optimized, interactive simulation that is continuously 'regularized' by the photons hitting our retinas.
class 2 and class 3 are mutually exclusive. You cannot legally have an e-bike that supports throttle up to 20mph that can also continue to e-assist if you pedal up to 28mph. While it's technically possible in software to switch between these modes, consumers aren't supposed to be able to do this on their own.
that's a nice bike! bummer that the rear rack isn't co-sprung.
From the article:
It also features a throttle good for 20mph where regulations allow.
That must mean they have a class 2 option.
In the U.S., there are 3 classes of e-bike: Class 1: pedal-assist only up to 20mph (helmets optional for adults) Class 2: same as Class 1 but with optional throttle to 20mph Class 3: pedal-assist only up to 28mph (helmets required, adults only)
There's also a maximum power rating of 750 watts for all of these. I'm not sure where the "pedal by wire" feature is from a regulatory perspective, but to me this fits into either class 2 or 3 depending on what option you get.
The e-bike market has multiple tiers/segments. This is not priced to compete with brands like Rad Power Bikes, Lectric, or Aventon. It's likely going to compete with brands like Tern, Benno, Gazelle, Trek, etc.
edit: ask yourself why the median new car in the US sells for over $50k when you can easily find cars for less than half that price.
mid-drive e-bikes like this one are generally more expensive also but more efficient than rear hub motor systems. They also provide better overall weight distribution.
a full suspension e-bike, 500+Wh battery, with a belt drive for $4,500 is honestly a really good deal. There is a shortage of options when it comes to full-suspension bikes that are good for commutes. Compare this to any e-bike with the Bosch e-bike system. The big risk here for consumers if whether they can match the service, support, and reliability that Bosch has. There appears to be a class-2 e-bike option which is something that significantly differentiates it from bikes with the Bosch system.
gotta listen at 2x speed!
this isn't necessarily true. While it generates less direct revenue, it increases nearby land value in two ways: 1) business activity which would have taken place on that parcel "overflows" to nearby parcels, ie, the demand for those other land uses doesn't go away and increases prices in the surrounding area. 2) the park provides real value to its users and access to that value also increases nearby ground rents.
