New comment by teytra in "A shell colon does nothing. Use it anyway"

I think colon at the start of a line was used for labels for goto statments.

https://www.in-ulm.de/~mascheck/bourne/PWB/goto.1.html

  DESCRIPTION
     Goto is allowed only when the Shell is taking commands  from
     a file.  The file is searched from the beginning for a line
     beginning with `:' followed by one or more  spaces  followed
     by  the  label.  If  such a line is found, the goto command
     returns.  Since the read pointer in the command file  points
     to  the  line  after  the label, the effect is to cause the
     Shell to transfer to the labelled line.

Like a money-back guarantee?

Like you get when you buy e.g. MS products?

I don't know much about her, but isn't that just communist propaganda? Labeling anyone who wants to get free from Maduro and return to democracy as "fascists".

They don't have a Vision Zero? (Plan for 0 deaths).

Norway has ~100 persons killed in traffic per year, but is not satisfied with that:

Quite a few modern cars do.

Drivers often don't, so it might be an improvement.

But note that it actually takes energy to break down the protein.

If you eat 100 kcal protein your body burns 20-30 kcal to process it. And you will feel more satiated than with the same amount of carbs.

Interesting. Is it possible to add what sources you use for each datapoint? The Acts and Epistles of course (verse numbers would be nice), but you use more sources, right?

Set columns to 6, and the pattern is changed in an "interesting" way.

All primes are n*6 +/- 1 (after the primes 2 and 3 that are "special").

Since English is not my mother tounge, I looked it up.

Oxford actually has (as one of three definitions):

either member of a married couple or of an established unmarried couple. "she lived with her partner"

a person with whom one has sex; a lover. "make sure that you or your partner are using an effective method of contraception"

Seems that Americans have a very weird 'love and hate' relationship to anything related to sex.

New comment by teytra in "Is 1 Prime, and Does It Matter?"

teytra — Mon, 21 Apr 2025 22:34:42 +0000

When I was younger I had a period I often was thinking about prime numbers (before I got old and started thinking about the Roman Empire).

I noticed the same as you, and IIRC the (some?) ancient greeks actually had an idea about 1 as not a number, but the unit that numbers were made of. So in a different class.

2 and 3 are also different, or rather all other primes from 5 and up are neighbours to a multiple of 6, (though not all such neighbours are primes of course).

In base-6 all those primes end in 5 or 1. What is the significance? I don't know. I remember that I started thinking that 2*3=6, maybe the sequence of primes is a result of the intertwining of numbersystems in multiple dimensions or whatever? Then I started thinking about the late republic instead. ;)

Yes that is my understanding too. Short chained saturated fat to be exact, so don't tell any of the lipophobics or they will automatically add the prefix "unhealthy" to it as they are accustomed to.

The point is how much of the carbs are you actually getting. The fibers that you excrete isn't part of your net intake.

For a non-monotheist, like Genghis Khan, religious tolerance would not be something "special" you have to grant.

It is the monotheists that has problems with other religions.

Norway is special. 94.3% of new cars sold last month were electric cars.

Actually, in the private marked it was 96.7% !
