journeemanon Filling the Void of a Physical Whiteboard

Nice! Would be better if one could, a) scroll to increase canvas-space and b) zoom out to step back a bit and take a look at the whole drawing.

journeemanon Featherweight Go

There's an upcoming talk by Philip Wadler on this paper on June 8 - http://chalmersfp.org/

YouTube channel where the talk will be streamed live - https://www.youtube.com/channel/UCiGOzKde1rlvzEB7J73gvrQ

journeemanon Pernosco: Fast, Fun, Omniscient Debugging

Rookout - https://www.rookout.com - is a related tool. Very handy!

journeemanon Physics, Topology, Logic and Computation: A Rosetta Stone (2009) [pdf]

This is great! Thanks.

journeemanon Mathematical Chronology

It doesn't seem to mention the works of the Indian mathematicians from Kerala, India on calculus. I think their work predated that of Newton and Leibniz.

journeemanon 40,000-year-old bracelet made by extinct human species found (2015)

I agree! Our (subconscious?) arrogance of our intellect always biases the way we look at our ancestors. If we could just be more humble, we would probably be seeing more of what's there.

journeemanon How SSH got port number 22

Thank you for the wisdom. :)

journeemanon How to Study (2016)

Great cartoons! :D

journeemanon A Strange Thing Happened in the Stratosphere

Did this affect Google's Project Loon in any way?

journeemanon SpaceX successfully lands its sixth Falcon 9 rocket after launch

I know it's too early but, I'm already kinda getting used to this.

journeemanon Ask HN: Systems whose concepts spring from programming languages/paradigms?

Cool. Another example could be of IPC in distributed operating systems borrowing from message-passing in CSP or the Actor model although, it could be also be the other way around?

journeemanon Schools Are Slow to Learn That Sleep Deprivation Hits Teenagers Hardest

I agree. I used to make the same mistake. Until I realised that it is best to go back to how people slept before electric light was invented; i.e. it is best to align your sleep cycle with the Sun's movement.

Of course, maybe it's harder to do this nearer the poles but, in the tropics we get near equal hours of day and night.

I have found sleeping early and staying away from modern tech 30-45 mins. before sleep to be _immensely_ beneficial.

journeemanon Geometric Folding Algorithms: Linkages, Origami, Polyhedra

Thanks!:-)

journeemanon Geometric Folding Algorithms: Linkages, Origami, Polyhedra

Could you please post the URL?

journeemanon A Decade of Container Control at Google

1) Will enterprises eventually shift to a DCOS?

2) Is it even worth it or necessary as afaik, even the biggest of enterprises' infrastructure needs are considerably less than those of internet companies?

journeemanon Polymagnets

Software-defined magnetism?

journeemanon Collective Memory Discovered in Bacteria

I wonder if there is some Sussman's Propagator model like biochemical process going on underneath, resulting in the collective memory.

journeemanon OpenRoads

This just brought back so many memories! Thank you! :-)

journeemanon TiltBrush by Google

This is great! Is there a similar app for sculpting in VR out there?

journeemanon Beware of HackerRank

HackerRank can be a very good way to screen developers before interviews. The author and most people in the comments nearly say, "Algorithms are useless. Writing efficient algorithms?! Who needs that?" :O

Some of the complaints are that HackerRank doesn't test things like team work. Of course, it doesn't! It's a good tool to screen developers. Things like team work, creativity and domain knowledge can only be tested in interviews.

I am not saying HackerRank has no issues but, discounting the importance of algorithmic problem-solving is very unwise, imo.

journeemanon Six-Legged Giant Finds Secret Hideaway, Hides for 80 Years

How so?

journeemanon The Japanese Art of Self-Mummification

I doubt pride is a strong enough force for anyone to undergo such intense suffering as this.

journeemanon The Japanese Art of Self-Mummification

I agree, ;-) but honestly, that title didn't prepare me for the content.

journeemanon Want to Write a Compiler? Read These Two Papers (2008)

'Compiler Construction' by Niklaus Wirth[1] is a pretty good book too. It's got the hands-on feel of Crenshaw's book with a quick but, not too superficial, introduction to theory. The book is little more than 100 pages long.

The compiler is written in Oberon however, which is also the source language (actually the source language is Oberon-0, a subset) but, Oberon is super simple and can be learned on the go.

journeemanon Physicists use photons to carry messages from electrons 1.2 miles apart

Why are photons required to "act as the messengers of an electron's spin"? Entanglement works without any communication between the entangled particles, right?

journeemanon Forty Minutes with a Fields Medallist

Wow, how inspiring! Thanks for the post.

journeemanon Illustrated Book on Indian Mars Orbiter Mission

It's a book for kids. It looks really fun! Fun > aesthics, for kids.

journeemanon Illustrated Book on Indian Mars Orbiter Mission

The problem is India's yet-to-be-perfected indigenous cryogenic engine for the GSLV (Geo-synchronous Satellite Launch Vehicle), which I suppose is required for launching into a geo-synchronous orbit.

journeemanon Defining an Escher Drawing with Julia

And the best way to find the right abstraction barriers is 'wishful thinking'. :-)

Greatly reduces the 'Invent and fit; have fits and reinvent!' cycle.

journeemanon Reconsidering Functional Programming

Isn't the author basically saying, an iterative process (process as in procedure-semantics; like the word is used in SICP) is better than a recursive process?
