arc_of_descent··on How old: deep learning age estimator from Japan
It guessed correct for me, 40. I'm 38. I'm Indian.

Incorrect for a picture of my mother who's 62. It guessed 34. And the picture is of decent quality.

arc_of_descent··on New Horizons: Nasa spacecraft speeds past Pluto
Ridiculous downvoting.

Check outworlder's post for the xkcd link, you petty graphic artists!

arc_of_descent··on New Horizons: Nasa spacecraft speeds past Pluto
Does it really matter? I remember reading about this in one of Richard Dawkins' book (I think its Unweaving the rainbow). Now you can complain about the Crab Nebula, whether its color correction, or you are lucky enough to view it up close with a naked eye.

The colors you observe are just models of the different frequencies which our brain has evolved into to label as "red", "violet", or "#782". :)

A much less/more evolved brain (be it alien or terrestrial) will observer it much differently.

Sorry to bring biology into this :)

arc_of_descent··on Ask HN: Do you get impatient when learning new things?
I'm currently learning Clojure by reading the Clojure Programming book. Its really been a struggle. You're right about the impatience part. I think everyone goes through it at one point or another.

Especially with learning a Lisp language, you can be really frustrated by having to read so much before you can actually create something.

But slowly and surely I'm learning. I just re-read the chapter(s) I don't understand over and over again.

So my advice is don't try to skim over a whole book. Try reading as slow as possible, and if you don't understand something, take a break and then get back to that same shit once more. And of course, write some code as soon as possible.

arc_of_descent··on Sourceforge Hijacks the Nmap Sourceforge Account
I just wish they'd give up their domain name to someone worthy. Source Forge. Conjures up Gandalf for me.
arc_of_descent··on How to boost your Vim productivity
I use 'fg' a lot. Thanks for the '%' tip. Now to practice and grow some memory muscles!
arc_of_descent··on Ask HN: What are you doing to improve your health?
30 mins of barefoot walking/jogging on a Treadmill. Lift weights for around 10 mins after that to work on upper torso.

Do try the barefoot walking technique. Its really worked well for me.

arc_of_descent··on Show HN: What do you think of my new startup ProductChart.com?
Very nice implementation.
arc_of_descent··on Ask HN: What are some nice electronics courses that blend theory and practice?
Thanks for the recommendation. I just purchased the Kindle version. I'm not really an electronics guy, but have always been interested in how it works. Will do by best to put this book to use!
arc_of_descent··on Ask HN: I've learned a programming language – how do I solve problems with code?
http://rosettacode.org/wiki/Rosetta_Code

I'm currently learning Python and I did the Letter Frequency problem and I'm now working on the Bulls & Cow problem. I highly recommend you visit the website and pick a random task(s) and solve it using code.

arc_of_descent··on Show HN: Four numbers can predict your lifetime risk of a heart attack
A good metric would be the hours spent per week in doing cardio exercises.
arc_of_descent··on ISRO Mars Orbiter Mission: Spacecraft successfully enters Martian Orbit
Congratulations!
arc_of_descent··on Show HN: Memory Chimp – How good is your working memory?
Nice game. I finished the game. Had some trouble with the last level. What I memorized was what my hand movements (mouse) needed to do.

I assume you're talking about landline phones.
arc_of_descent··on Why Sometimes I Hate Myself
I thought the OP was rating himself 9 on a scale of 1-17!
arc_of_descent··on Why Sometimes I Hate Myself
Its a perfectly rational feeling. The problem is we also like to perceive ourselves as individuals, but in fact are products of a system.

I spend huge amounts of my time watching movies, doing things absolutely not related to my personal career ambitions, and yes I do feel guilty. But as this thread mentions, we are human, and the feelings pass away in time.

I've learned that one hour of focused productivity is worth 10 hours of "doing stuff" which you think will make you a better programmer.

arc_of_descent··on Android One
Most of rural India does not even have electricity. I wonder how they are going to charge their Android Ones.
arc_of_descent··on Submarine Cable Map 2014
Does each cable actually lie at the sea bed? What if the route comes across a really deep part of the ocean?
arc_of_descent··on Scale of the Universe
Nice!

Beautiful beautiful movie! Sorry didn't read the article though. I'm going to watch the movie again today. Work can wait!
arc_of_descent··on Docker 0.8: Quality, new builder features, btrfs, OSX support
I just tried the docker interactive tutorial. It was fun, but I still don't get the point of using docker. Just been hearing a lot about it, and its getting too much buzz.
arc_of_descent··on 67 Signals hasn't changed a thing
Some good humor here! Enjoyed it.
arc_of_descent··on Perl is 26 Today
It prints the greater variable between $x and $y.

[$x => $y] creates an array reference. => is just a fancy syntax for a comma. So its actually [$x, $y].

[$x => $y]-> dereferences the array ref.

$x <= $y is a boolean expression which return 0 or 1. Accordingly the array index is chosen.

Sorry if I'm unable to explain properly! Here's a script.

    #!/usr/bin/perl
    use strict; 
    use warnings;

    my $x = 8;
    my $y = 9;

    print [ $x => $y ]->[ $x <= $y ];

Ha ha, your nickname says it all. Back when I started programming in 2000 all my yahoo, MSN and skype (when it was released) accounts either had the word linux or perl in it.

Then unfortunately I had to become more professional and started using my real name. :)

CGI::Application too supports PSGI via CGI::Application::PSGI. I prefer CGI::Application as it is minimalist and very customizable.
arc_of_descent··on Perl is 26 Today
That's cool. :) But I'm sure the correct statement would be untangling messy code written in "your non-favorite language" and rewriting it in "your favorite language or management's choice based on buzzwords". :)
arc_of_descent··on Perl is 26 Today
Been using Perl for almost 10 years now. I've used Perl for almost everything. Web development using CGI::Application, developing my own web framework, console apps (using the ncurses library), POE (Perl Object Environment), Web socket stuff and more.

My main job currently involves maintaining and developing a huge code base in Perl including three websites (soon to expand to much more). Perl just works. I thoroughly enjoy coding in it. I've not spent too much time optimizing and testing code though. mod_perl is pretty fast in itself (using Apache).

That being said Perl certainly lacks the in-built features which would make meta programming a quick and easy job. Yes, I still have to start using Moose. Perhaps in 2014!

Happy 26th Birthday Perl! Without you, I wouldn't have a job!

arc_of_descent··on Debian 7.3 is out
Since I do apt-get update && apt-get upgrade almost regularly, I found out that my system was already running 7.3 (cat /etc/debian_version). So yes, this is not a major upgrade release just that the Debian team thought that there were enough changes and bug fixes to label this as a new release.
arc_of_descent··on Primer on elliptic curve cryptography
If its too TL;DR for you to read right now, just read the first page. It's a great introduction to RSA and the use of prime numbers with real examples.
arc_of_descent··on One-electron universe
Electric utility companies charge you for the energy they provide via electrical energy.

I remember reading an article saying that in an electrical circuit it is not the electrons that are moving, but the energy. The electrons are just the medium.
