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.
Is there a short but decent RF/antenna crash course? I’m fascinated by the topic — though the prospect of going through a textbook and revisiting the physics rabbit hole gives me massive anxiety (it always ends up recursing to philosophy).
It is about more than just the calorie content of the food.
Unless your digestive system is hyperactive, a lot of this huge glob of fat will likely just pass right through without being absorbed into your bloodstrean.
The refined sugar is virtually guaranteed to fully hit your bloodstream and right now. It's enough to send some people into a life threatening diabetic coma.
After eating a pound of fat, you may want a nap but dying from it is extremely unlikely.
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...
You're gonna have to locate yourself for this comment to make any sense. Plenty of places still get snow regularly in winter, and nothing humans can do will change that
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.
Yes! Going cross-platform is on the roadmap, but right now we're focused on building out the feature set and improving the form factor.
Also yeah, Kernel refers to onkernel - they call it that because they're running the browsers in a unikernel. They're a great product and you should give them a look if you need hosted browsers!
In the early stage of a startup/product the most important thing is usually fast development loops, to add features and, most importantly, figure out what the product needs to be. It usually makes sense to focus on that, which means deferring later projects (such as porting to other platforms) which are also important, but aren't part of the figuring-out-the-product loop and so can come later.
This of course is frustrating for users who want the product but aren't using that platform. But also a good sign that someone wants the product enough to complain about this!
I am just wondering from technical standpoint. Their product doesn't seem like it would be doing anything OS-specific, so I would expect that it would be multi-platform without them having to do anything.
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.
