And who needs more than 640 kilobytes of memory anyhow?

You may be amused to learn about these, then: U+2012 FIGURE DASH, U+2013 EN DASH and U+2212 MINUS SIGN all look exactly the same, as far as I can tell. But they have different semantics.

Heck, even maintaining my computers at home requires documenting things! I have lost count of the number of hours I’ve lost trying to rediscover how or why I set things up the way I did.

The flare-out is really difficult to get right, from what I’ve read. As soon as you start leveling off, air speed is going to drop really fast, and you have very little time to get that bugger on the ground before you get in a stall. They u

That mechanism is so well known, it’s trivial to undo by removing the +service part. Is it really effective? How would you even find out if it is?

For single window apps it makes sense that closing the window also quits the app. For apps that can have multiple windows I suppose it would make sense for the app to quit when the last window is closed, but that seems less obvious that it

Lissssp – lotss and lotss of ssilly parethesises! We hates it! – Quoted by memory from comp.lang.lisp years ago. (Sorry, can’t remember by who.) Really, I get the parenthesis hating: It is truly terrible to have to deal with them unless you

Indeed. The biggest hospital where I live (Trondheim, Norway) is still running at reduced capacity and over budget a year after moving to an Epic derivative. Doctors and nurses are burning out, many talking about moving elsewhere. Being rec

Pilot errors also have underlying causes. Was the pilot properly trained for the particular situation that arose? How is the safety culture of the airline? Did some aspect of the airplane design make that mistake more likely, or hinder the

I guess old unix persons do use bc. But even older unix persons, like you and me, use dc. Oh, and I still have my trusty old HP48GX calculator that I bought nearly thirty years ago. Algebraic notation is fine for paper, bur RPN is best for

That’s really a strong reason, is it not? I have no idea for how long humanity has tracked the seven day week, but suspect it’s been well over 2000 years. That’s a lot of tradition to discard.

It’s fun to think about, but frictionless means you’d have to pump out the air. So you’d need to wear a space suit, and heat shielding. It’s kinda hot down there.

Me neither, but it makes sense to me in the case of an error that is relatively easily corrected. If a proof is fatally flawed, however, I would not use that term.

Yes! In fact, as you go down the borehole, gravity will decrease linearly, until it reaches zero at the center. Strictly speaking, not quite linearly, since the earth’s density is not uniform. Thinking of the earth as made up of concentric

Calibre won’t do it out of the box, but you can install third party software to do the de-DRMing, and Calibre will use it if present. At least that is how it worked years ago. I think the Calibre web site (if not the app itself) had pointer

I attended a short series of lectures by Kalman years ago. As I recall it, he very strongly emphasised the virtue of working directly with observed data, avoiding the biases resulting from positing a model and trying to adapt it to the data

But fingerprint unlocking didn’t work with wet fingers, like outside on a rainy day. I find that face unlocking fails less often than fingerprint unlocking ever did. (Though outside on a sunny day can be challenging.)

Kibibyte: 1024 bytes. Gibibyte: 2^30 or 1,073,741,824 bytes. The -bi suffix is intended to signify “binary”.

Or they could stick with binary and introduce a name for 1/1024th of an inch. Borrow a meme from the “almost SI” prefixes kibi, mebi, gibi etc., and call it a mibi, perhaps? ;-)

A mile an hour sounds rather like a leisurely stroll to me.

Not complaining really. I mentioned this mostly for entertainment value, besides pointing out that things are not always as straightforward as it might seem. (Also triggered by the absurd precision of the number in the title.)

The title of the post could make you think that a degree of latitude varies by less than a decimeter, but that is of course not true. But close enough for many practical purposes, definitely.

I’m puzzled by this. How hard is it to convert prices by powers of 10? Do the same thing with $/lb and $/oz, and I’d be lost. Edit: Oh wait, I get it. It’s just that a price per 100 g is an order if magnitude less than per kg, so

Those cases are the best, are they not? But yeah, a large dose of sarcasm was intended. And a little bit of seriousness.

You missed a few intermediate units, which might help somewhat to explain it: Derived from surveyors’ tools, a chain is 22 yards. (It is also 4 rods, making a rod equal to 5½ yards; go figure.) Ten chains make a furlong, and there are 8 fur

Not so quick: One inch may be 1/12 of a foot, but a foot is not necessarily a foot. The international foot is 12×2.54 mm, but a US survey foot is 1200/3937 m. The ratio of the definitions is 500000/499999.

In my experience, syncing my iphone over wifi doesn’t really work. It will start fine, then lose the connection before it’s finished. Perhaps my old (2010) airport extreme is not up to the task? But in any case, I just use the cable instead
