Fuel and food are excluded from core inflation not because they're unimportant (they are in fact incredibly important) but because they are much more volatile in price--going up and down in bigger increments--so that you get a more s

As a maintainer, discovering that a PR is AI-generated just absolutely saps any motivation I have to actually review it. I've never been a great reviewer, and AI means I have to watch out for really different kinds of errors. There&#x2

I'll give an analogy to email and spam. A lot of effort has been spent making sure that if an email is from x@example.com, it actually came from x@example.com, giving us things like SPF, DKIM, and DMARC. And it turns out that the most

One of the explanations I've heard is that a lot of traders were caught out by how quickly the economy rebounded from COVID-19, so they're overcompensating by underreacting to the current situation.

The fee for filing a lawsuit by itself is $405. That's before any lawyer touches anything and you get to find out how high a lawyer's hourly rate is. A simple, easy lawsuit will cost you in the same range as a house. Even if you w

The exact kind of scenario I was thinking of is something like a driver barrelling down a road in a school zone at 35 mph and hitting a kid who ran out into the street to pick up a ball. Since you so love putting words into my mouth, I assu

No, it's actually fairly common in crashes between motor vehicles and pedestrians (or cyclists) to place most or all of the blame on the pedestrian. When the Uber self-driving car struck and killed the pedestrian, not only did the inte

This gets to the heart of effective type rules, which are complex, confusing, and not properly implemented by compilers. C and C++ definitely diverge here, because C is less ambitious in its object model (which mean it just simply leaves so

If you have 29 arguments, I assure that you some of them are on the stack in nearly every architecture in use. Also, certain types as parameters also get passed on the stack (usually types larger than a register, or in C++ code, objects wit
