In the HN comment that the article discusses [0] is the conclusion that commenter a1369209993 is correct (there are as many between 0 & 1 as 1 & +INF) and llm_trw is not correct? I got a bit confused.
Also, the article links to a blog by Daniel Lemire [1] in which he says (with regard to producing an unbiased random float) "picking an integer in [0,2^32) at random and dividing it by 2^32, was equivalent to picking a number at random in [0,1)" is incorrect and there is a ratio of up to 257:1 in the distribution so obtained. Not wanting to disagree with Daniel Lemire but I can't see why, and a quick experiment in Python didn't give this ratio.

You can put an extra 'level' in, to make both options return the same 0,1...9
def loop():
for number in range(10):
def outer(n):
def inner():
return n
return inner
yield outer(number)

Currently reading "Byzantium: The Surprising Life of a Medieval Empire" by Judith Herrin[0]
It's very interesting, a sort of missing piece of history from my point of view. At school those centuries was just skipped as 'the dark ages.'

It may be different on newer MacOS but on mine you will need ping6
> ping6 ff02::1%en1
for example.
I wasn't able to get it to work on Windows (I can get the command to work in WSL but it seems to sit alone in an internal network). Any advice welcome.

When I started my first job in 1995, the old hands were still using DEC ALL-IN-1 [0] from terminals on their desks but it was in the process of being phased out (for Microsoft Mail or something on Windows for Workgroups), so I never got to use it myself.

In my youth I had a ZX spectrum which had BASIC with line numbers and no renumber command. Sometimes when adding code I'd simply run out of line numbers so had to GO TO an unused block of line numbers, put the new code there and GO TO just after the original code. I've never quite recovered from that.

It's a consequence of being block-based as mentioned elsewhere, but interesting to note that cat'ing together bzip2 files gives a valid bzip2 file. That's the basis of pbzip2 [0] - it breaks the input file into chunks of 900K by default, compresses each chunk and then concatenates the compressed chunks. The individual chunks can be compressed in parallel if hardware allows.

A role reversal from the 1930's - the first Canon cameras used Nikkor lenses!

And could one swap between the two backends with the same VM image (.vbox +.vdi) to see which one gave the better performance?

'Go' was named because "it's short, easy to type"[0] though I assume it being part of Google was also a contributing factor?

Might depend on what kind of book it is - do you have a lot of images, tables, cross-references, ... or is it mostly plain text?

There is such a thing[0] - at one time I was using both and it made my poor head spin a bit.
