$585B on new fabs, $357B on AI data centers, and $5.8B on humanoid robots. One of those numbers is not like the others

Run because cardiac health and general fitness are important. Manage calorie intake if your only goal is weight loss

> avoiding all sugar

I don't think you understand macros if you think a breakfast of yogurt, berries, and milk is avoiding sugar. Berries are mostly sugar, and lactose is a sugar which makes up a significant portion of yogurt and milk's calories. Your breakfast is close to 50% sugar. I would hate to see what the macros look like when you're not "avoiding all sugar".

Also 150 calories of whole milk is 8 fl oz. How big is your morning latte? Milk is a great food for bodybuilding, because it's easy to consume a bunch of calories without feeling that full. This makes it less good when you're trying to lose weight.

> apparently, 10 pounds of weight loss is roughly a clothing size [XL → L → M]

What? This is so wrong I'm confused how it could have possibly made it in. As a 5'7" guy, I was a M at 145, and still an M when I hit 175, though at that point I was close to an L. There is no way I was 3 separate sizes during that time

It's an odd article, because it claims that shops being open until 10pm (after a siesta break) is the solar-based schedule

This is the most significant record in running to fall since 1954 when a sub-4 minute mile was run. I think running can be front page news once a century

> always

Can you be more specific here? In an article about civilization 5300 years ago, where India has had a human population for at least 65,000 years, saying "always" is fairly vague

The average monthly payment for a used car in the US in 2025 was $532, according to https://www.experian.com/blogs/ask-experian/average-car-paym.... This does not count insurance, taxes, parking, or gas.

A status symbol will easily run you $1000/mo. I currently pay $350/mo (including cost of capital), and I don't know how I would pay less for a car that's not actively falling apart. Chevy Spark, manual transmission, $7k KBB value, averaging 500 miles per month.

This is a really cool hack, and I wish I could pay for things with a dumb watch. It's just the right level of useful and silly to be up my alley. But the article, as others have mentioned, is a little off. The author did not "invent" the guess-and-check method for verifying resonance. That's been a staple of radio since the beginning, which is why original tuner dials were actually variable capacitors

> Therefore, an ideal antenna should consist of a 22.12 metre long wire, but by convention fractions of λ-lambda (λ/2, λ/4, λ/8, λ/16, etc.) are opportunely chosen.

This sentence is confused enough to be incorrect. λ/2 is generally preferred as an antenna length (standard dipole configuration) because it will resonate at the appropriate frequency with desirable standing wave characteristics (current maximum and zero voltage at input, voltage maximum and current minimum at ends). λ/4 can be used as a half-dipole, but it requires a ground plane to resonate properly. There are also arguments to be made for a 5λ/8 antenna, but none that I'm aware of for λ/8 or λ/16.

In practice for small antennas, physical length and electrical length are only tenuously related, so it's a matter of creating a circuit that acts like an antenna of the chosen length.

Note that a kg of fat contains about 9000 calories, while a kg of sugar contains about 4000 calories, so this is really a startling claim, if true

I was surprised to see "An Abundance of Katherines", given that it's not John Green's newest or most highly regarded work. I looked into the comments to see why it was being discussed, but it seems to be a classification error - all of the comments are discussing "Abundance", the political nonfiction book by Ezra Klein and Derek Thompson. That one makes more sense on the list, given that it was released this March

The neat thing about electric cars is that they get cleaner as the grid gets cleaner. If you bought an EV in 2015 (when this report was published) and were worried about the grid mix, I have good news for you. Electricity production from coal in the US is in the process of falling off a cliff, dropping to 15% of the electricity mix in 2023 from over 30% in 2015. https://wolfstreet.com/wp-content/uploads/2024/02/US-electri...

> only available for Mac so far, sorry!

Is there a plan to change this? Building on Electron should make it manageable to go cross-platform. 2026 will be the year of the Linux desktop, as the prophecies have long foretold.

Off-topic, but Kernel refers to https://www.onkernel.com. A bit of an awkward name

Yes, this was in fact an explanation of a joke. "In Soviet Russia, Rome is a poor city" requires both a currently-existing Soviet Russia, and Rome to be a part of it. Both of those are far-fetched. "Russia seems poised to invade Europe in the near future" is a bad explanation, since they are currently invading a country geographically in Europe.

This also applies to getting in a car with a human driver, or to driving yourself. Or to any other way of getting from point A to point B
