• Commented on Tabs vs Spaces. Article about symbols that are used for indentation in 3.8 million Perl files on CPAN
  There are several issues that are not being considered. First off, the code for analysis looks at every line. It should ignore all blank lines, lines that are within POD ( /^=\w+/ .. /^=cut\s*$/ ), all lines that are solely...
• Commented on As simple as possible...but no simpler
  Damian's communication style (in person, in presentation, in writing, or in any other form that I've interacted with him) is always so clear. This is yet another example of why I love the Perl community: we're trying to do better...
• Posted I'm not positive about this... to Bob

  I'm not positive about this, but I'm not sure that things are behaving as I would expect. What would you expect the following lines to output?

  perl -E 'say "x"; say -"x"; say -"-x"; say -"+x";'
  

  For me, lines 1 and 2 make sense. Lines 3 and 4 …

  Ah, thank you Aristotle! You have cleared up some subtleties in the language that I knew were there, but were quite hard to pin down. Thank you for taking the time to clearly explain those subtleties, and give an example...
• Commented on What's going on here?
  Tom: If it were taking `@_[0,1]` as a scalar parameter, it would be printing out `2`. That's what happens with `sprintf(@_)`. It's clearly taking in two parameters, but for some reason the second parameter is being coerced from a number...
• Posted What's going on here? to Bob

  What do you think the following lines print?

  This is a fine example of why prototypes should not be used on user-created subroutines; just memorizing what they are for the built-ins and expecting the syntactic effects they have is hard enough.

• Cuong Manh Le commented on As simple as possible...but no simpler

  You version 4 must be:

  ```
  constant vanEck's = 0, {@_.end - (@_.head(*-1).first(@_.tail):end:k//(@_.end))}...∞;
  ```

  Otherwise, we will get undefined error on `$N`.

• Vinny commented on As simple as possible...but no simpler

  I learned a lot reading this--thanks! Your explanations are so clear, and the improvements in speed you got from thinking and algorithm improvement makes the idea that perl6, which might be 30% slower than xyz language, moot. I'm trying to switch to perl6, and hope you keep up this quality of blogging!

• Damian Conway commented on As simple as possible...but no simpler

  Yes indeed!
  Thanks for spotting that.
  I've corrected it in the text.
  Much appreciated!

• byterock commented on Tabs vs Spaces. Article about symbols that are used for indentation in 3.8 million Perl files on CPAN

  IMHO the bloger would of better off spending his time doing a few pull requests and fixing some bugs then spending a bunch of time exaiming the ages old 'tab' vs 'space' debate.

  Since the days PC computers got more than 640K of disk space on a floppy it has stopped to be an issue.

  In the good old days of 64k many of old farts would argue for 'tabs' as the took only 8 bits of less memory than while '4 spaces' took up 32.

  In the big scope of things it really doesn't matter much
