Oatseller··on Ludwig: A type-based declarative deep learning toolbox

Oatseller··on Ternary Trouble in Perl
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:

Oatseller··on The Feynman Technique: The Best Way to Learn Anything
> Citation needed.

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"

Oatseller··on Google to Remove Chrome “Close Other Tabs” and “Close Tabs to the Right” Options
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.

Oatseller··on Ask HN: How should I start with modern JS?
A good place to start is MDN (Mozilla Developer Network): https://developer.mozilla.org/en-US/

MDN Javascript resources: https://developer.mozilla.org/en-US/docs/Web/JavaScript

Before starting the tutorials, take some time to learn what's available in the Firefox developer tools. You won't need most of them at first, but knowing what's available will help as you gain experience.

The two developer tools you'll probably use most when leaning are the Scratchpad (https://developer.mozilla.org/en-US/docs/Tools/Scratchpad) and Console (https://developer.mozilla.org/en-US/docs/Tools/Web_Console)

https://jsfiddle.net/ & http://jshint.com/ will also be very useful while learning JS

I haven't taken any but Udacity has some javascript courses (https://www.udacity.com/courses/all), just tick the "Javascript" checkbox under "Technology" in the left menu

Oatseller··on Learning Human Identity from Motion Patterns
tl;dr

   8. Conclusion

    From a modeling perspective, this work has demon-
    strated that temporal architectures are particularly efficient
    for learning of dynamic features from a large corpus of
    noisy temporal signals, and that the learned representations
    can be further incorporated in a generative setting. With
    respect to the particular application, we have confirmed
    that natural human kinematics convey necessary informa-
    tion about person identity and therefore can be useful for
    user authentication on mobile devices. The obtained results
    look particularly promising, given the fact that the system is
    completely non-intrusive and non-cooperative,i.e. does not
    require any effort from the user’s side.

    Non-standard weak biometrics are particularly interest-
    ing for providing the context in, for example, face recog-
    nition or speaker verification scenarios. Further augmenta-
    tion with data extracted from keystroke and touch patterns,
    user location, connectivity and application statistics (ongo-
    ing work) may be a key to creating the first secure non-
    obtrusive mobile authentication framework

Oatseller··on Predicting the Future with Google Maps APIs

    Does it mean that the new traffic predictions, as well as the
    increased waypoints limits, are not accessible via the JavaScript API
    except for Google Maps for Work customers, but they are accessible to
    the general public via some other API?
It appears so, but they state "for now" so I'm guessing it will be available (hopefully) soon.

    What is the non-JavaScript Maps API?
There are Java and Python client libraries: https://developers.google.com/maps/web-services/client-libra...

Oatseller··on ASLSpeak: Intuitively decode sign language using the Leap Motion, and speak it
I originally found this on MSDN BLOGS: http://blogs.msdn.com/b/microsoft_student_developer_blog/arc...

    Like Nick Bowmen (18) and Nelson Liu (18, pictured left). The duo
    forms team ASLSpeak - winner of both the Microsoft Hack Award and the
    EMC Isilon Hack Award.

    Knowing they wanted to create something to help the disabled in some
    way, they came up with an idea that aims to aid American Sign Language
    (ASL) speakers.
Truly inspiring work.
