There are two issues here.

First, in list assignment the first array or hash will soak up all remaining values not yet assigned.

    my ($first, $next, @rest, @empty) = (1, 2, 3, 4, 5);

  

$first is now 1

$next is 2

@rest is (3,4,5)

@empty is undefined;

see: http://perldoc.perl.org/perldata.html#List-value-constructor...

The second issue is that the split() function takes an optional "Limit" argument (split /PATTERN/,EXPR,LIMIT)

This causes the example code (split /-/,$str2, split /;/, $str4) to be evaluated as split /-/,$str2,split(/;/, $str4) which evaluates as split /-/,$str2,2

Here, split /;/,$str4 evaluates to 2 because, in scalar context, split returns the length of the resulting list - since there are two elements after splitting $str4 it returns 2.

In this case, the result of splitting $str2 results in two elements so the limit doesn't matter.

If $str2 were 'This-string-has-many-dashes', the result of (split /-/,$str2, split /;/, $str4) would be:

    array 3[0] is: This
    array 3[1] is: string-has-many-dashes
    array 4[0] is: 
    array 4[1] is:

It starts at about 30 minutes

Somebody needs to reverse engineer the video.

They've updated the video to remove the initial 30 minutes of silence

Ah, wonderful.

There aren't any, I searched the last time the "Feynman Technique" was posted on HN and found that the term originated on Youtube [0] in 2011.

When challenged by a commenter for a source the Youtuber stated:

> The technique is inspired by Feynman, not used directly by him.

> I was inspired by the story I shared in the beginning to formulate

> his more informal approach into a method. You can see him talk

> about understanding the math ideas in his book "Surely You Must Be

> Joking, Mr. Feynman"

From there it appears that "inspired by" has transformed into "created by"

Thanks, that's what I thought. The article could be clearer about this.

It's called Hyperthymesia [0], the actress Marilu Henner has it and "can remember specific details of virtually every day of her life since she was a small child" [1]

Agreed. I use those features multiple times per day, along with "bookmark all tabs" which shows even lower usage so they'll probably do away with that feature as well.

Like you, I imagine most who use those features are using chromium and not sending those stats to Google.

Elsevier was also recently awarded an "Online peer review and method" patent which earned the August, 2016 "Stupid Patent of the Month" from the EFF [0].
