WAV is uncompressed. MP3 is highly compressed, but lossy. FLAC is compressed and lossless. If you wanted to store lots of master copies of audio, you could use WAV or you could red…

Interesting, thanks. Is your chair anything special? I'm guessing it has a high back for head support?

> I recline while I work Can you elaborate on this? Sounds like it might be a way to limit back strain? Do you have a desk at all?

So basically, if there's a distribution of possible outcomes (with estimated duration plotted on the x-axis, and probability on the y-axis), then we put bounds on either side of th…

So one question here is: Why reduce the distribution (with long tail or whatever) to a single estimate number? If the distribution represents the range of possible outcomes well, t…

Yes, I don't see the logic of using fertile agricultural land for solar PV. It seems like short term thinking and a planning failure. I've heard at lest one similar story regarding…

How long before the riots and total societal breakdown?

This is anecdata, but I don't think it affects my overnight sleep if my nap is post lunch, although it definitely does if I sleep later in the day, say from 4pm to 6pm. I think the…

As I understand it REM sleep is at the start and end of each cycle, thus 45 mins would put you squarely in a deep non-REM phase. That said, the cycles get progressively shorter in …

I find if I'm working on a difficult problem, I feel like I can make more rapid progress if I take a 'nap' early afternoon in that post lunch drowsy period. I often start thinking …

I frequently go down rabbit holes like this, one such journey resulted in this port of Timsort to C#/dotnet: https://github.com/colgreen/Redzen/tree/master/Redzen/Sortin... Availab…

In my experience it's often quite obvious when someone doesn't understand something and they say they do. Someone who properly understands will typically offer some tidbit of feedb…

Iran is ominously missing any cases according to this data. I guess you could say Iran is a known unknown.

If you cross byte boundaries, i.e. compactly pack the bits such that there are no wasted bits; then you have 4 bits per decimal digit, 50T digits becomes 200T bits == 25TB. Technic…

For one, a database may receive a query such as "WHERE x >=10 AND x <=100". I.e. having an ordered index is useful for accessing ranges, whereas a hash lookup is always just for a …

Yeh. I had one pull request accepted into dotnet core a couple of years ago; I wonder if that was enough to be included in that 25k number?
