It's probably good for young people to learn to do arithmetic by hand. I think you'd lose some important cognitive ability if you never learned arithmetic other than to punch things into a calculator. Not so much because of arithm

Are there proposed reasons for increased blood flow to brain regions other than neural activity? Are neurons flushing waste products or something when less active?

One conclusion is that they should start having more children or their economy will keep on dropping. An inverted population pyramid in a high-entitlement society will lead to economic collapse.

Just because something is hard to enforce doesn't mean it's absurd. Embargoes aren't impossible to enforce against the foreign importer. If a foreign entity is found to have placed orders with false documents, they can be san

setHTML needs to support just about every element if it's going to be the standard way of rendering dynamic content. Certainly <svg> has to work or the API isn't useful. SanitizeHTML functions in JS have had big security hol

There's no way to plan a city so most people can walk to a Costco. Warehouse stores are an inherently car-based phenomenon.

I already had a VPN, because I live in the UK and do business in the US, and the easiest way to get websites to show local prices & shipping is a VPN. I think anyone that is involved with multiple countries needs one. Localization was s

Yes, they transfer money from poorly informed people to well-informed people. That's the point. That's how they reward well-informed people for the service of making good predictions so everyone can be slightly better informed. Th

The change to non-skeuomorphic style at least made it faster. Liquid Glass makes it simultaneously harder to read and slower.

Laptops are pretty rugged, but with more sensitive stuff like prototypes or test equipment, the easy solution is to put it in a plastic ziploc bag while it's warming up.

Inductors (the L of LC) are large and expensive except at very high frequencies. So audio circuits are normally designed with just resistors and capacitors. And you always need an active component like a transistor. A pure LC can oscillate

I'm trying to imagine a conversation with a Bell engineer in the 80s explaining that, in the future, a 4-year old phone won't be expected to call 911 any more.

The account-owning thread has to accept messages for every atomic action you need it to do. There are lots of standard shared queues you can pick from that have been fully regression tested. That's almost always better than mixing conc

Aha, that's just what I wanted!

It's not necessarily shared. You could assign a single thread to own the account balances, reading requests from a message queue. That probably scales better than locking. A single thread can do several million transactions per second,

I draw the line where I can't expect the default gcc on most Linux and Mac systems to compile my code. And I don't want to force them to install a particular compiler. -std=c++20 seems to work pretty reliably these days. We'r

The demo with an inline 8 at 16000 RPM is hard to judge, because I've never heard such an engine IRL. Might I suggest adding demos of engines people know the sound of?

To be pedantic, an aircraft's MTOW is a function of the structural strength of the airframe and landing gear and doesn't depend on conditions. The Regulated Takeoff Weight is what depends on temperature, air density, headwinds, ru

Unlike Linux, MacOS, and Windows, which are all completely finished. But also: most of the work of an OS is supporting a variety of hardware. That's not very intellectually interesting work. Hardware is usually hacky, and since was onl

In an alternate universe, we'd all be using descendants of these instead of the 8086. Part of what killed it, besides not having the economy of scale in microprocessors, is that optimizing compilers got good at turning loops over integ

It's remarkable that it's so hard to create high magnetic fields. 35 T is only 35 times higher than what's in a regular loudspeaker or brushless motor. The electric field possible in a lab must be much more than 35x what&#x27

It's suspicious that the most important truth should contain "most important" within its statement. If you tried asking an LLM to rank the following: 1. "1+1=2" is the most important fact in mathematics. 2. "1-

Tesla and Waymo must have huge data sets that could be used to correlate driver badness with the appearance of their vehicle. It's probably not in their interest to publish such data, but one can hope.
