Things 50: Portal, Legalising Street Racing, Supply and Demand

(Originally sent June 2009)

An unusually long multi-lunch-break-requiring Things in unintentional celebration of hitting 50…

Things blog update
My attempts at setting up two WordPress blogs from a single database failed. I will see if I can set up a second database instead for a Things blog, in between revising for my IDM exams.
[Ultimately, that’s exactly what I did. – T.M. 28/5/11]

Film
Yesterday I saw Sam Raimi’s Drag Me To Hell. It was an extraordinary experience that is difficult to describe – imagine the kind of inventive unpleasantness that happens to Wile E. Coyote applied to supernatural horror, maintaining some of the comedy aspect, and you begin to get some idea. The trailer sets out the premise very clearly but dramatically underplays the scares:

IMDb rating: 8.2
Rotten Tomatoes aggregate: 95%

Videos
This week I finally got around to playing Portal, a short but brilliant game which, for me, achieved the astounding feat of living up to its own considerable hype. Even if you’re not a gamer, the trailer is worth checking out just to see how nifty it is:

If that doesn’t float your boat, here’s a video of a cat that jumps into and out of a tall box. 1’19” is where the best jumping starts happening:

In a fascinating case study for debates on the merits of legalising/criminalising things, police in Florida have been running legal street races in which, for $25, people can attempt to “Beat the Heat”. They claim that given this controlled and safer outlet, they have seen a drastic reduction in illegal street racing.

Quotes
Gavin Potter, a leading entrant for the NetFlix Prize (see this wired article) said:

“The 20th century was about sorting out supply. The 21st is going to be about sorting out demand.”

In other words, by solving problems of supply (think of all the information/products/services available to you via the web), we create a new problem related to demand – how do we sort through all this stuff?

I saw this articulated in the supermarket last week. A child had clearly been sent to pick up some juice, but was just staring at the shelving three times his height stocked with perhaps a 100 variations on fruit juice. His father turned up and asked what was wrong, to which the child replied with palpable desperation: “I can’t find any fruit juice!”

Here is a lovely graph demonstrating the relationship between Star Trek‘s warp speeds and energy requirements:

On a side note, in Star Trek the ships generate a bubble of distorted space around the ship, which to an outside observer means the ship appears to elongate as it sets off at warp speed. In Star Wars the ships instead enter hyperspace (warning: no basis in science), a kind of parallel universe in which distances are shorter / the speed of light is faster, so no elongation occurs.

Criminally, warp elongation was added to ships entering hyperspace in the Star Wars special editions.

This Week’s Puzzle: Buttons
Why are buttons on clothes for males placed on the opposite side to buttons on clothes for females?

Last Week’s Puzzle: Newspaper Eyeball Value
Last week I asked (roughly speaking) why newspapers are complaining about the internet when many have successful online sites with ads alongside articles just as in the print versions. I received some detailed responses and there’s clearly a lot more research that could be done, but here’s some of the main points:

1) Actually the main newspapers in the UK seem to be perfectly fine, with stable or even growing circulation figures. As JB put it: “I think alarm bells are being rung by consumers that don’t like the net and shareholders with unreasonable expectations!”

A corollary – in a blog post that could desperately use some editing, an argument is made that the important part of a newspaper is not the news (a commodity) but the package and the curation, somewhat consistent with the Gavin Potter quote above.

2) Newspapers cost money to make and to buy. The website version costs a certain amount of money to make but scales much more cheaply, and is free to the consumer. Depending on the scale and margin of each branch, this will give very different results for any given newspaper.

3) Demographics. With TGI I can see that the median age of the most regular newspaper readers (top 2 quintiles) is about 17 years older than the median age of those that regularly visit newspaper websites. The rule of thumb is that who sees your ad has the strongest effect on how well it does (over and above the offer or creative itself). Still one would expect that better targetting leads to better results, and if anything the splitting up of the audience should make targetting easier and hence more profitable.

4) Visibility. Since people get web content for free, they have less invested in it, so are unlikely to read it as attentively (A study suggests people typically read 20% of the text on a web page). Online ads can be blocked, newspaper ads can sit around the house for some time, paper is still easier on the eye than screen, people are more likely to be multi-tasking online… and many other factors similar to this exist.

There are many other arguments and deeper points to be considered about the above, but I would want to be more sure of the data before claiming to have an answer. I may revisit this topic with a more detailed investigation at some point on my blog.

Puzzle: Newspaper eyeball value
We often hear that newspapers are in terminal decline and it’s all the internet’s fault. But much of a newspaper’s revenue comes from advertising, and many have created their own ad-supported websites, and many of these websites reach very large numbers of people. So they are losing eyeballs looking at print and gaining eyeballs looking at a screen, both of which will also see adverts. Why isn’t this helping?

(Perhaps more than other puzzles I have set in the past, there are many possible answers. Don’t hedge your bets – if you have multiple solutions, put them in order of importance! I’ll summarise the results and stick my own oar in next week.)

Things 102: Bionic Cat Ears, Brilliant Journalism, Drawable Monsters

This Week’s Puzzle
I have a Tumblr on which I post daily things to draw, called Now Draw This. I really want to make sure I credit the relevant artist when I post a piece of artwork. (I should do that with the photos too, but for various reasons that’s not as important to me).

TinEye is an awesome reverse image search engine, which in the past has helped me track down artwork even when the version I had turned out to have had the colour palette significantly edited. Pretty clever.

The problem is, this site posted the above image (of Ico and Yorda from the game Ico), and neither TinEye nor wily Googling is helping me track down the original artist.

Can you find out who created the above image originally?

Video
Technology expands the range of things we can do. As a society we try to keep up by generating some kind of idea of what we should do. For example, mobile phones enabled us to use ostentatious ringtones. For a while they were everywhere. Now, it seems we’ve collectively decided that’s not such a good idea.

So here’s something I hadn’t even considered: what if you could collect some kind of real-time usually-invisible data about yourself, and then manifest it with a clear physical signal? Would that ever be a good idea?

Michael Lewis writes long articles on complex but important topics, that are nonetheless incredibly engaging, thus creating pretty much optimal long-form journalistic pieces. I highly recommend that you make time for his article Beware of Greeks Bearing Bonds (which I thought I’d linked to before but can’t find in my records), and if you like that then you should also read When Irish Eyes Are Crying.

Quote
Joe Cornish, director of Attack the Block, interviewed by Little White Lies:

If you look at a lot of the digital creatures in Harry Potter, you couldn’t go home and sketch them – you’d need a draughtsman’s degree. […] The charm is to go home and feel that it’s possible to figure out how they did it. When I was a kid, I’d go and see Ghostbusters and spend the next day trying to draw the Stay Puft Marshmallow Man, or trying to get the logo right. They had a graphic simplicity that was much more infectious and warm and authored than a lot of the stuff now.”

I had the same childhood experience, and I think it’s a really fun rubric. Attack the Block‘s creature design succeeded in exactly that way.

Last Week’s Puzzle
Last week I asked what the purpose was of this insect-eye mirror I saw on the ceiling in a bank in Vienna, but nobody hazarded a guess.

You can tell from the shadow that there’s a bright spotlight pointed at the mirror, so my hypothesis was that it was some kind of way to generate a bright, ambient light throughout the room. But it seems like overkill / overdesign if that’s the goal. And why would you want to have a diffuse, shadowless light that badly anyway? I like to imagine, completely baselessly, that there’s a local superstition about some kind of money-stealing creature that inhabits shadows. But if you can think of something more plausible, do let me know.

Things 48: Bike Parkour, Limits of Men, Wolfram Alpha

(Originally sent May 2009)

I’m considering switching to a blog format for Things in time for Things 50. Let me know if you have any strong feelings on the subject. [You’re now looking at it! – T.M. 28/5/11]

Video
Danny MacAskill does parkour/free-running but on a bike. Having seen these kind of videos before, I know a lot of them are clearly a collection of flukes edited together – but in this case the man has a staggering raw skill and most of the things he does (with the exception of the first) you get the feeling he could pull off 10 times in a row.

A slow build up, but worth it:

Quotes
Two quotes capturing a similar idea – decide for yourself just how gender-neutral ‘man/men’ is in each case:

“Every man takes the limits of his own field of vision for the limits of the world.”
– Arthur Schopenhauer

“Men perceive the world from their own point of view, which they confuse with absolute truth.”
– Simone de Beauvoir

With no regard to downplaying expectations, Wolfram|Alpha is going to attempt to launch within the next 24 hours. In some sense a web front-end for Mathematica, it will essentially curate public knowledge (population demographics, poker probabilities, mathematical algorithms, and who knows what else) and make it queryable with natural(ish?) language.

The hype:
“Wolfram|Alpha is in a sense the “killer app” for Mathematica. It is a chance for Mathematica to show off the astonishing range of things it is capable of doing when it is deployed, not against a specific problem, but against all problems.”

A lovely little .pdf summarising the ‘quest for computable knowledge’ in 2 sides of A4, where Wolfram|Alpha is naturally the next great step.

A bit of geekish chest-thumping as they assert how mighty their works are.

Showing off the maths bit.

The Reality:
From Douglas Lenat:

“[it] covers a large portion of the space of queries that the average person might genuinely want to ask. […] It handles a much wider range of queries than Cyc, but much narrower than Google; it understands some of what it is displaying as an answer, but only some of it […] The bottom line is that there is a large range of queries it can’t parse, and a large range of parsable queries it can’t answer.”

Assuming they can withstand demand, you will be able to try it for yourself very shortly – they will commence launch preparations at 1am tonight / tomorrow morning.

[Of course, it’s now live, and Lenat’s observation remains accurate – T.M. 28/5/11]

Puzzle answer: The Space Stick
Can information travel faster than light if you poke an incredibly rigid stick one light-year long? The answer is no. As many of you observed, ‘pushing’ a solid object does not magically transfer force instantaneously through it, but rather creates a compression wave as atoms or molecules push up against one another, and this is bounded by the speed of light. (There’s also the issues of the necessary rigidity being impossible, the huge amount of inertia you would be working against, needing something to push against, and gravitational complications if you’re anywhere near a planet or other large celestial body).

Many of you chose to focus instead on the general problem of faster-than-light communication. In summary, quantum entanglement does involve ‘spooky action at a distance’, but fascinatingly stops just short of being spooky enough to transfer information. Wormholes, on the other hand, are seemingly permitted by General Relativity, which would seem to lead to paradoxes, and remains a mystery.

This week’s puzzle: Wired’s “Color Scheme”
The US issue of Wired this month is guest-edited by J. J. Abrams and features a lot of interesting puzzles as well as a meta-puzzle (I think). I highly recommend ‘Color Scheme’, which you can try here [link broke, try here – metatim 03/08/15], although you’ll have to resist just clicking for the answer on the link bizarrely placed immediately below the puzzle.
