I agree: clickbait. She unpacked the toilet; I doubt it was anything like what you or I would think of as "cleaning a toilet."

Lots of replies with good ideas here. The biggest question is that EMI resistance; do you really need to ignore brief closures? In the vast majority of situations, the answer is no.

Agreed. The writer is pretty loose with their comparisons:

* What does it mean for "performance per dollar" to get faster? Higher, maybe; rise faster than it has in the past, maybe, but just "faster"? Nope.

* The article cites some equipment as being "2x cheaper". I think they mean "half the cost", but if so they should say it.

> I absolutely prefer anything with classic instruments (Jazz, Classical) in higher-quality formats

High-dynamic-range material benefits from lots of bits.

I have about 2500 CDs in my garage, with all of them ripped to my laptop. I'll never lose access to them. (My only regret is that I can't look through the jewel case covers and booklets.)

Yes, but note that your cited article doesn't talk about "more granular" or "less granular"; it talks about "fine-grained" and "coarse-grained".

I hate the use of "granular" in a relative context. If water is not granular, and ice cubes are granular, what does it mean for some ice cubes to be more granular than other ice cubes? Are the cubes in question larger or smaller?

"Denied Fast Index Entry" is a much more honest title than "Rejects SpaceX", which is just click-bait.

He said that it got a few resistor values wrong, but other than that it was correct. I assume it was actually a single-layer board. (Nobody's doing this with a mini-ITX motherboard.)

A friend had the power supply die on his high-end turntable. He took a picture of each side of the supply's PCB, handed it to Claude, and it gave him back a schematic.

The day was somewhat stormy. I was in my kitchen in my north-suburban-Boston house, when I suddenly heard a BOOM. I thought it was a very large branch falling on my house, so I ran outside to check out the roof. Saw nothing, and only later heard about the meteor.

I have a Donegan DA-5 OptiVisor Headband Magnifier. They're nice, because the lenses are prism'd so that you can focus on something close without having to go cross-eyed.

We watched all of The Ascent of Man in middle school. The only thing I remember is that when the narrator, Jacob Bronowski, gestured with the back of his hand (fingers up), he always tucked his middle finger behind his ring and index finger. I assume this was so that he wouldn't "give the finger" to the audience.

(I've been wasting neurons on this for fifty years...)

I saw the first Star Wars movie on the day it opened in Boston, in an enormous, packed theater. I will never forget the roar that went up when Han Solo came out of the sun to save Luke.

Yeah; they had a wonderful earthiness to their language; both highly technical and highly vivid. Like this comment on hexanitroisowurtzitane:

> Recall that this is the compound whose cocrystal with TNT is actually less dangerous than the pure starting material itself, and yeah, I know that sounds like the guy at the pet store packing a starved Komodo dragon into the carrier with your new dog, just to calm him down some.

I'm guessing he just ran out of nasty chemicals. Either that, or he got tired of it and followed his muse elsewhere.

Isn't infrared, by definition, wavelengths beyond what people can see?
