prakashk··on YouTube's CEO limits his kids' social media use – other tech bosses do the same
The hypocrisy is not because they are limiting access to their kids.

It is because they are limiting access to their kids, while actively creating and executing algorithms to increase user engagement even to the point of making people addictive and dependent on their platforms.

prakashk··on The joy of reading books you don't understand
Is there a path (short of going through a Physics undergrad curriculum itself) to enjoy and get more 'return' from Feynman for someone without formal Physics background? Any recommendations of books to read prior to undertaking Feynman?
prakashk··on India cuts periodic table and evolution from school textbooks
I hope you aren't using the "everybody does it" argument to normalize, or worse, justify this stupidity.

That every country has its share of people who engage in such backward-looking, glorifying-the-past behavior does not make it right.

prakashk··on Ask HN: Something you’ve done your whole life that you realized is wrong?
Do you, by any chance, mean to say "gait" analysis, instead of "gate" analysis?

If not, can you please explain what "gate analysis" is?

prakashk··on Error messages in Haiku?
Normal error message in Perl:

    $ perl -Mstrict -e 'say $x'
    Global symbol "$x" requires explicit package name (did you forget to declare "my $x"?) at -e line 1.
    Execution of -e aborted due to compilation errors.
With the addition of `Coy` module [1]:

    $ perl -Mstrict -MCoy -e 'say $x'

Every (most?) special variable has a non-cryptic alias, if only one were disciplined enough to choose to use the alternative.

Hopefully, the author discussed it in detail in her book.

prakashk··on Chart of the Decade: Why You Shouldn’t Trust Every Scientific Study You See
> Is it not possible that the low-hanging fruit had been found earlier, in the 1970s-1990s, and the problem got harder?

The problem of "problems getting harder" is a continuous phenomenon. Why would that be the case suddenly after 2000, and not before?

> However, I'm a bit puzzled by the weird direction the journalist ran with this, which is straight to his preconceived notions that are not that supported by the data he's looking at.

Is it possible that your own preconceived notions about the author and the publication may have caused you to judge this way?

In any case, don't trust every comment posted on Hacker News (including my own) :)

prakashk··on Permanent Daylight Saving Time? Florida Says Yes, but It’s Not So Simple
India, UTC+05:30, all through the year. Despite having widely different climate zones in various regions of the country, there is no "Daylight Saving Time".
prakashk··on A CEO's Guide to Emacs (2015)
No need for a separate preprocessor. org-mode offers org-babel which enables you to practice "literate programming" to create your init file, where you interleave text and code.

Here's are couple of examples: https://github.com/howardabrams/dot-files/blob/master/emacs....

> The only gripe I have with emacs help, is that it does require some basic skill to use it.

The only thing to know is to press 'q' to quit the help window and get back to where you were.

prakashk··on Advanced Data Structures
Take a look at the recently released "Grokking Algorithms" [1] by Bhargava. Uses Python for code examples. I haven't read it personally, but has good reviews on Amazon [2].

prakashk··on Netflix Now Only Has 31 Movies from IMDB's Top 250 List

    I think there's fairly strong evidence that the answer would be "yes" to that question.
I doubt that. Netflix didn't start with original content. They had to spend many years acquiring their substantial member-base before they started experimenting with the original content. If the company literally launched with House of Cards with no existing members to speak of, it would have been much tougher for them to convince people to pay them money and watch their as yet unproven original content.

prakashk··on Tell HN: New features and a moderator
Favoriting doesn't appear to work for me. When I click on the 'favorite' link on an article page, I am taken to my favorites page, and nothing is shown added to the list. I only see the message "To add a story here, click on its timestamp to go to its page, then click 'favorite' at the top."

Using Firefox 47.0 on Ubuntu 16.04. uBlock Origin shows "0 requests blocked".

prakashk··on Hiring Is Broken – My interview experience in the tech industry
Since those are companies to avoid anyway, you are not losing if you are rejected because of an honest "I don't know" answer.
prakashk··on Curing Our Slack Addiction
Many IRC channels are archived and the archives are searchable, so the information is not necessarily lost.
prakashk··on Larry Wall Unveils Perl 6.0.0
See cpanminus [0].

From [1]:

    cpanminus (cpanm) is an attempt to make a zero-configuration client
    that automatically does the right thing for most users. It's also
    designed to run well on systems with limited resources (e.g. a VPS).
    It doesn't come with Perl, but it's easy to install.
    It integrates easily with local::lib.

prakashk··on Keystroke shortcuts in bash
C-r is reverse-search-history. You press C-r and start typing your search pattern to trigger an incremental search. Most recent command matching the pattern anywhere in the command is selected.

In contrast, history-search-backword requires you to start typing your pattern followed by the keystroke it was bound to. The most recent command that starts with your search pattern is selected.

prakashk··on Ccat – syntax highlighting cat
I use the highlight package[1] that comes with Debian/Ubuntu. With that:

    highlight -O ansi file.ext | less -R
    highlight -O xterm256 file.ext | less -R
highlight can also convert the input to other formats: HTML, XHTML, RTF, LaTeX, TeX, BBCode or SVG.

An alternative to `less -R` is the `most` pager [2].
