othello··on Color Photography of Early 1900s Paris
I'm almost sure it was taken at the Grand Palais.

othello··on Psy Makes $8.1 Million By Ignoring Copyright Infringements Of Gangnam Style
Those $8.1 million did not come from Youtube advertisement: according to the original AP article, only $870,000 did.

https://www.google.com/hostednews/ap/article/ALeqM5jlcpd0qGl...

This estimate seems to be based on views for all of PSY's channel, i.e. 1.3 billion views. That works out as a $0.7 eCPM, which seems more credible than the $8 floated below in this thread.

othello··on Intelligence Council Predicts 3D Printed Organs, Megacities, Brain Chips by 2030
Global trends 2010 from the National Intelligence Council.

Surprisingly, the direct link no longer works, so I had to go through archive.org

othello··on One-molecule-thick material has big advantages
Indeed, from the fourth to last paragraph: "The material is so thin that it’s completely transparent"
othello··on Micro-apartments next for S.F.?
To put this in a European perspective: the legal minimum floor area to rent out an apartment in France is 9 square meters, or slightly less than 97 sq feet.

Even better (or worse, depending on your perspective): the absolute minimum is a volume of 20 cubic meters [1].

Therefore in cities like Paris where flats with high ceilings abound, you find owners of big, old apartments with 3m high ceilings breaking them up in 7 sq meters (75 sq feet) "studios"...

250 sq feet is aplenty.

othello··on Indus Valley Civilization’s Collapse Explained
"They had cities ordered into grids, with exquisite plumbing, which was not encountered again until the Romans"

It's amazing how quite advanced technologies (for a civilization that thrived from 5000 to 3000 years ago) were mastered only to be lost later over the course of history.

A mind-blowing example closer to us is the Antikythera mechanism [1]. Found in a Mediterranean wreck in 1900, the artifact was not analyzed until the 1950s, when it was found to be "a mechanical computer designed to calculate astronomical positions" - except it was made in the first century BC.

Wikipedia notes that "Technological artifacts of similar complexity and workmanship did not reappear until the 14th century, when mechanical astronomical clocks were built in Europe."

It is the oldest known mechanical computer - and to my knowledge no comparable device was to be manufactured until the 17th century and the invention of the Pascaline [2]. That's 18 centuries of gap, right there.

The precision of the clockwork and the exactitude of the astronomical calculations made by the Antikythera mechanism only goes to show how much knowledge was lost in Europe after the fall of the Roman Empire. Progress does not always follow a straight arrow.

othello··on After the age of scarcity
"If you're lucky you will have patrons, not customers."

Probably the best quote from the post. Soon the only way of making a living from a creative endeavour might be to be funded by patrons, then releasing your content for free. A generalized Louis CK model if you will.

Funny how that would bring us back to pre-18th century days where patronage was the only business model in town for creative types, with all the constraints that came with artists-patrons relationships.

Except in this world everybody would get to play Medicis or Louis XIV. I certainly hope that "crowd-patronage" will mitigate the limitations of artistic freedom that often came with traditional patronage.

othello··on Python Application Deployment with Native Packages
Deploying web apps as self-contained binaries reminds me of Go [1]. Except in Go you get this for free as a simple (and swift) compile step.

Of course, this is true of any compiled language that can produce self-contained binaries, but Go has the added benefit of being well adapted to web app development.

othello··on If you can't remember why onions are in there, take 'em out.
This piece of advice is quite at odds with another classic piece:

http://www.joelonsoftware.com/articles/fog0000000069.html

Back to that two page function. Yes, I know, it's just a simple function to display a window, but it has grown little hairs and stuff on it and nobody knows why. Well, I'll tell you why: those are bug fixes. One of them fixes that bug that Nancy had when she tried to install the thing on a computer that didn't have Internet Explorer. Another one fixes that bug that occurs in low memory conditions. Another one fixes that bug that occurred when the file is on a floppy disk and the user yanks out the disk in the middle. That LoadLibrary call is ugly but it makes the code work on old versions of Windows 95.

othello··on Future Timeline
For those who did not get the xkcd reference either:

othello··on Religion may become extinct in nine nations
What do you make of France, which with Ireland has the highest fertility rate in Europe (2.01 in 2010 [1]), while Catholicism can hardly be described as thriving there: 4.5% of French people go to mass at least once a week [2].

Social policies such as benefits for families with two or more kids and low-cost, widely available day-care centers for children under 3 that allow women to work and have kids sound far more important to me than any "residual Catholic natalism".

othello··on Was Einstein really a poor student?
Thank you for pointing the mistake out.

However, it is not so obvious that 6 is the highest score. While it was the case in Switzerland (where Einstein was studying at that age), it was the exact contrary in Germany at that time - 1 being the best score and 6 the lowest.

As pointed out in the Stack Exchange's answers, this discrepancy in scoring systems may also have contributed to the myth of Einstein's poor performance at school.

othello··on Was Einstein really a poor student?
Here is Einstein's certificate for the year 1879 (he was 10):

http://www.scienceblogs.de/frischer-wind/einsteins-zeugnis.j...

Long story short, he obtained the best score (6) in the three mathematical topics (algebra, geometry and descriptive geometry) and in physics.

I guess one of the reasons the myth has endured so long may be that it makes for such a great story. A sort of intellectual rags-to-riches, so to speak.

Edit: corrected the physics score.

othello··on You can't do that
Surprisingly enough, this can even happen in academic environments that should know better.

Though far from the level of difficulty presented by jacquesm, the same thing happened to me with an end-of-term project a few years back.

We had to make a small piece of software in Java. Most of my mates were going for boring stuff, such as sudoku solvers or small neural networks to play the likes of Connect four.

I wanted to make a Gameboy emulator.

"You can't do this", said my professor. "At least not in two weeks' time."

Well I don't remember much besides coding during those two weeks, but guess what - after 14 days, my program could boot Tetris. No sound, granted, but it was playable.

My professor was quite the sore loser though - he considered the program incomplete since it only booted a few roms, didn't have sound and could crash randomly. I ended up turning in a gameboy rom dissassembler instead, complete with GUI and breakpoints setting.

Still, never believe that "you can't do that".

othello··on Fukushima is a triumph for nuke power: Build more reactors now
The article dates back from yesterday, 1pm GMT. More evidence that there should be no conclusion drawn (one way or another for that matter) on nuclear energy safety or lack thereof before this whole catastrophe has fully unfolded.

Though the more recent developments would seem to point out that Quake + tsunami >> 1 minor radiation dose.

othello··on Hosni Mubarak finally steps down
And Mubarak's Wikipedia entry is already edited:

Muhammad Hosni Sayyid Mubarak was the President of Egypt from 1981 to 2011. [1]

History unfolding live indeed.

othello··on The Commuter Bike Redesigned and Electrified
As a matter of fact, bicycles are one of the oldest and most refined technologies available to us.

Bicycles can hardly be considered an old technology. While Da Vinci had already sketched some designs in the late 15th century [1], the first prototypes could not be built before the early 19th century.

The first recognizable version of the current chain-driven models was only produced in 1885. [2]

The chain-driven bicycle is not as simple as it looks.

othello··on World's worst hacker
Still, this leaves you wondering how someone with such little knowledge of even the most basic Linux commands could ssh in there in the first place. Any idea ?
othello··on So Long and Thanks for all the Bits
This is the kind of message that reminds me that HN is not eternal.

That one day, it will be remembered as a precious community, surprising in the quality of its members and the stability of its standards. A sort of modest, modern day digital Athens if you wish.

So let's enjoy it to the fullest while it lasts, and thank you Jacques, for all the invaluable contributions you brought to the community.

othello··on Time Investment
Amanda Hocking is probably the best example right now of an author who made it big through ebooks without having been published traditionally first.

She does have a blog [1] and promotes herself quite heavily through social networks, but she's never had the support of a big publishing house that Konrath had.

She's far from being an overnight success though - in an interview with the Huffington Post [2], she explains how she's been writing fiction constantly from the earliest age, attending every possible writing courses along the way.

othello··on Impact (Javascript Game Engine) Sales Report
When you're writing a game engine, your main concern is performance. Not using the built-in javascript sqrt() and rolling out your own would be woefully inefficient.

That question would have made more sense for an engine in C, building your own fixed-point sqrt() for example.

othello··on Impossible for the HN crowd: Do nothing for 2 minutes
Well done, the waves are actually quite relaxing.
othello··on How To Use Amazon EC2 as Your Desktop
I have been doing this for a year with a Linode small instance and it works like a charm - although I only use it through a Putty terminal.

I had initially set it up to code small ruby scripts remotely that help me with my day job (mostly to scrape websites with the excellent Scrapi gem). Since IT would not let anyone install anything on their computers, but still left port 443 wide open, I gave it a try.

The added benefit is that working on a linux box through Putty forces you to learn a real terminal text editor - in my case Emacs. I guess I can thank IT now ;)

othello··on Google Turns Your Android Phone Into An On-The-Fly Conversation Interpreter
I would also add to that list the Emotiv kit (http://www.emotiv.com), which allows "to create applications that can be controlled by your mind" by making use of the same type of technology that allows paralytics to control robotic arms.

Actually, the technology alone is highly impressive, but that an SDK is available to anyone for $299 is nothing short of mind-boggling.

othello··on (Android) Developer Income Report #6
How many ad impressions does the $1,700 Android revenue correspond to?

Thank you again for posting these numbers every month.

othello··on For what are the Windows A:\ and B:\ drives used?
This reminds me that even us twenty-somethings may one day be made every bit as clumsy and baffled by whatever comes up 30 years from now as our own proverbial mothers are today...
othello··on There is no place for just shitting all over other people's work
The irony being of course that the critics themselves should start by reading a f*ing English grammar book and learn to capitalize the beginning of their sentences.
othello··on GameBoy Color Emulator in JavaScript
There is also GBATEK, from the no$gba emulator. It provides a full description of the memory map, interrupts, IO ports and rom layout for GB, GBA and now even the DS.

http://nocash.emubase.de/gbatek.htm

The CPU instruction sets can be obtained from the original manufacturers (ARM9/ARM7 for DS, ARM7 for GBA and Z80 for the original Gameboy - and the Color version).

othello··on Salesforce Buys Heroku (YC W08) For $212 Million In Cash
It's surprising that it comes out of the blue like this. Had there been any rumor of a coming acquisition in the past few weeks?
othello··on Apple Granted Patent For 3D Display Method
The actual patent abstract reads :

A three-dimensional display system provides a projection screen having a predetermined angularly-responsive reflective surface function. Three-dimensional images are respectively modulated in coordination with the predetermined angularly-responsive reflective surface function to define a programmable mirror with a programmable deflection angle.
