  Just to add why it works, atan2 is actually arctan of y/x. Same formula for angle of inclination wrt +x and slope of a line....

  Hi Laurent, One of the optimization I made is to do it backwards. Generate list of names ending with a letter which is NOT a starting letter of any name in the whole pokemon name list. These will be the...

• Posted Perl Weekly Challenge W024 - Smallest Script, Inverted Index to Yet Ebreo

  I've been doing the Perl Weekly Challenge (PWC) for 3 weeks now. So far there's been unique challenges that made me utilize different modules. I even submitted a solution using APIs which I haven't done in my work because I didn't have any reason to. (lol)

• Posted Perl Weekly Challenge W023 - Difference, Factors and Poem to Yet Ebreo

  This week's challenge is composed of three tasks.The first one is to get the n-th order of forward difference of a given list.

  Task #1 - N-th order difference:
  

  Suppose we have list (X) of numbers: 5, 9, 2, 8, 1, 6 and we would like to create 1st order for…

• Posted Perl Weekly Challenge W022 - Sexy Primes to Yet Ebreo

  I was googling about perl, hoping to see an active community that is dedicated to perl. I have been an active member of codesignal and I primarily use perl to solve the challenges. And then, I came across the website

• Aaron Priven commented on Is Perl 6 Being Renamed?

  In general, I think the "rename Perl 6 to Raku / rename perl 5 as perl 7" is a good solution, but I would suggest that the Perl 5 -> Perl 7 bump should happen only when there is at least something notable to include in it that would otherwise justfy the change. (Native OO system, non-experimental signatures with named parameters, something like that.)

  I mean, the big user-visible improvement in Perl 5.30 was "The upper limit 'n' specifiable in a regular expression quantifier of the form '{m,n}' has been doubled to 65534", which was pretty underwhelming. And so far, the most notable …

  Hi Yet,
  thank you very much for your input. I thought, when considering how to solve the task, about whether doing it backward would help, but could not see any benefit of doing so at the time. Right now, it is almost midnight here and I'm just coming back from a Paris Perl Mongers social meeting, meaning that I had some glasses of wine. Not the best situation to think clearly about your comments. I'll come back tomorrow evening and try to think more about your suggestions.
  Cheers, Laurent.

  Yeah, well, I understand what you mean and I mostly agree, Yet, but, strictly speaking, this is true only for x > 0. You have to add or subtract pi when x

  Oops, messages are cut off when there is the smaller than symbol in it.

  I try again:

  Yeah, well, I understand what you mean and I mostly agree, Yet, but, strictly speaking, this is true only for x > 0. You have to add or subtract pi when x is negative, and atan2(y, x) is usually defined for x == 0 (at least for values of y other than 0), even though y/x would lead to an exception when x = 0. I chose to give a geometrical interpretation of atan2 (the rectangular coordinates of a point in the plan) in my update to avoid having to deal with all these edge-case difficulties in al…
