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 reduce storage space by using FLAC instead.

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 the distribution and take a 'central' point on

by redcalx 4y ago
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, then the single number throws away most of the information in

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 reforesting, i.e., a scheme that was planning to

For the battery storage, perhaps they will ultimately choose https://en.wikipedia.org/wiki/Lithium_iron_phosphate_battery . The cable manufacture seems like more a 'when' rather than an 'if' problem.

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 there's enough time and mental exertion in the aftern

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 an overnight sleep, so it's possible a daytime nap slee

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 about the problems again immediately on wakin

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 feedback from their understanding as an acknowledgement

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. Technically there is still some slack in there because each 4 bit b

I agree, I think there are a few things in the Windows file explorer that conspire against its good performance (file preview is a big factor, but recycle bin content seems to affect it too), and it does seem to get worse over time. I think

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 single entry. The question then becomes - wh

Not really; if you find a block it will mostly likely have been beaten by someone else's block by the time yours reaches most nodes...unless there is a Saturn based side chain or similar.

The April 12th deadline is conditional on the PMs deal, if that doesn't go through then May 22nd is the current date at which no deal exit will occur if nothing else happens, i.e. that's the current letter of the law. So the vote(
