Since "N nines" for positive integers N denotes an uptime of 1 – 10^(–N), I think it's fair to analytically continue that formula, and say that 9% availability corresponds to 0.041 nines!

This is true as stated. However, it is important context that the time bomb was originally introduced in Trump's signature Tax Cuts and Jobs Act in his first term. So, yes, Trump's OBBBA fixed it, but Trump's TCJA caused it i

The converse and inverse are logically equivalent by contraposition, so it doesn't really matter which one you use. If you think through it, you can see that "if you're the product, you're not paying" is equivalent

I might guess that GP is referring not to interface ergonomics (for which a struct is a perfectly satisfactory solution, as you describe), but to implementation efficiency. A pointer is one word. A slice / string view is two words: a l

When we're talking scales like 10^-23, "one" and "one sixth" are comparable enough to warrant an "approximately".

This is what I was thinking, too. Without some kind of linearity, `connect` et al. don't give the claimed guarantees if you can just reuse the old socket handle. Especially if it's aliased in a list or something. I was surprised t

It can mean either. "Suspicious behavior" doesn't mean that the behavior thinks that you've done something wrong. "She's suspicious" can mean either that I suspect her intentions or that she suspects someo

Red/green has no inherent semantics. It has the semantics that you assign it. If you choose to assign it meaning that disenfranchises 8% of men using your system, that's your choice, but it is not a good one.

I have usually heard it called "A–AB–B migrations". As in, you support version A, then you support both version A and version B, then you support just version B. The rest of the sequencing details follow from this idea.

Sure. If T is a zero sized type, then chan T should just be an atomic int. I am not sure how much this improves code readability in practice—I see chan struct{} frequently, but I cannot recall ever having seen chan T for a zero-sized T othe

The term is correct. Grammatically, we would say, "I love vacuous truths", or, "I love vacuously true statements". (To my ear the second version sounds very slightly more appropriate, because in mathematics "vacuous

If you have a buffered channel with 100 "true"s in it, you're using 100 bytes. If you have a buffered channel with 100 "struct{}{}"s in it, you only need to store the length, since the element type is zero-sized.

Wow, so, connecting these dots: - reducing headcount by 50% down to ~70 people = firing 70 people - at a generous estimate of total burdened cost of $1M/person/year, that's $70M/year - which accounts for a full 5 year
