Things 114: Kern Test, Robot Bird, Social Graph, Too Soon To Say

Puzzle
This week, try testing your ability to kern.

If you liked that, try the splines.

Video
It’s easy to get overexcited about human progress, when in the grand scheme of things we’re still pretty small fry. I would periodically remind myself of this by considering that for all our ingenuity, we still couldn’t make a robot the size of a bird that could fly like a bird. Thanks to the determined efforts of Festo, I’m going to need to come up with something else.

Link
I’ve seen this link crop up in a few places now, but for good reason – I think this is some really important stuff that we are collectively getting wrong on a large scale right now: “The Social Graph is Neither” by maciej.

Cutting large swathes of great text for concision, here’s my favourite part of the  argument:

[…] declaring relationships explicitly is a social act […] Social graph proponents seem uninterested in th[is] signaling problem. […] [and] how does cutting ties actually work socially? […]  In real life, all relationships fade naturally if you don’t maintain them, but right now social networks preserve ties in amber until we explicitly break them […] Can I unfollow my ex now, or is that going to make her think I’m still hung up on her?

[…] You might almost think that the whole scheme had been cooked up by a bunch of hyperintelligent but hopelessly socially naive people, and you would not be wrong.

However, after a lot of good stuff, it ends with something of a shrug:

It’s just a matter of waiting things out, and leaving ourselves enough freedom to find some interesting, organic, and human ways to bring our social lives online.

I’m not sure that’s quite the right way to put it. I don’t think it’s about bringing our social lives online. Its more about augmenting our social lives with online functionality that goes with the grain of human nature.

That said, leaving ourselves enough freedom is critical. Quite how we do that is a topic for another day.

Quote
In the early 1970’s, Richard Nixon asked Zhou Enlai what he thought of the French Revolution. Zhou notoriously responded:

It is too soon to say.

Which everyone thought was quite wonderfully representative of Chinese sagacity.

This year it emerged that the whole thing was a misunderstanding too delicious to invite correction, as Zhou thought Nixon was referring to the much more recent student riots in Paris.

But this doesn’t matter, because the misread quote still stands as a useful reminder that we should err towards taking a longer-term view when evaluating the benefits of things. On a similar note, Ben Hecht says:

Trying to determine what is going on in the world by reading newspapers is like trying to tell the time by watching the second hand of a clock.

Last Week’s Question
Last week I asked: when someone says “next Thursday” on a Monday, which Thursday do they mean?

Richard’s response was the same as mine – always clarify. However, where I was aware of two interpretations, he identified three [This part added thanks to Richard’s clarification – T.M. 25/11/11]:

I have come across three possible scenarios:

|

(a) this = first occurrence, next = second occurrence
(b) this = occurrence in the week you’re in, next = occurrence in the following week
(c) this = occurrence in the week you’re in, next = first occurrence

|

I don’t think anyone actually uses (a).
Personally I use (b).
I have met people who use (c).

|

To give some examples, on a Tuesday, referring to “This Monday”
and “Next Monday”.

|

(a) This Monday = 6 days times, Next Monday = 13 days time
(b) This Monday = -1 days time, Next Monday = 6 days time
(c) This Monday = -1 days time, Next Monday = 6 days time

|

I can’t think of anyone who would use (a).  (b) and (c) agree.

|

Another example, on a Tuesday, referring to “This Friday” and
“Next Friday”.

|

(a) This Friday = 3 days times, Next Friday = 10 days time
(b) This Friday = 3 days time, Next Friday = 10 days time
(c) This Friday = 3 days time, Next Friday = 3 days time

|

(a) is indistinguishable from (b), hence somewhere who is a (c)
might assume upon hearing (b) that their algorithm is actually
(a).  I would use (b).  I have met people who use (c).

However, I now wonder if this is paranoia – how divided are we really on this issue? Do the vast majority of people use one of these interpretations? My plan is to start to collect instances of people using this form of date referral, noting on which weekday it was said, and which day they were intending to refer to. I’ll report the results here when I have enough data, which may take a few years.

Things 105: Pervasive Game Event, Monty Hall, American Politics

Upcoming Event, Thursday August 4th
People that like Things are very likely to like this. On Thursday August 4th from 7pm-10pm, Hide & Seek are running a Sandpit gaming event at the Southbank Centre. In practice this means you get to turn up and play lots of interesting games (for adults) for free. Having been to quite a few of these in the past, I highly recommend it as the games are always fascinating and inspiring. I’m particularly excited about this one because Clare and I will be running a game ourselves, one based on the age-old problem of tessellating pieces of cheese to make a perfect sandwich.

More details of the event can be found here, and the official Facebook event is here. Let me know if you think you can make it!

Puzzle – Monty Hall
After talking to some people about last week’s Two Envelopes puzzle, I realised that many Things readers may not be familiar with the Monty Hall Problem, which one should really understand before tackling the Two Envelopes. So I’ll state that here, then go through the answers to both in the following Things.

In the Monty Hall problem, you are in a gameshow presented by the eponymous Monty. You are asked to choose one of three closed doors. Behind one of the doors is a nice car that you apparently want to win. Behind the other two doors are goats. If you choose the door with the car behind it, you win the car. If you choose a door with a goat behind it, I don’t think you win a goat, but you definitely don’t win the car. Basically the goats are there just for comedic effect.

So you choose a door, pretty much at random. At this point Monty (who knows where the car is) opens one of the remaining two doors to reveal a goat. He does this in every episode of the show – whichever door the contestant chooses, Monty will always then open one of the remaining doors to reveal a goat. He then offers you the chance to switch from your first choice to the other unopened door. The question is: should you switch?

Sometimes The Onion packs a headline with so much satire it barely needs the accompanying article. Most recently I was impressed by American People Hire High-Powered Lobbyist To Push Interests In Congress.

Quote
From Jon Stewart’s speech at the “Rally to Restore Santiy”:

The press can hold its magnifying up to our problems bringing them into focus, illuminating issues heretofore unseen or they can use that magnifying glass to light ants on fire and then perhaps host a week of shows on the sudden, unexpected dangerous flaming ant epidemic.

This National Geographic healthcare data visualisation achieves a rare feat: showing the data in an unconventional way that nonetheless actually tells a story with the data quite well. Charlie Park has some great commentary on why a scatter plot of this data isn’t actually as useful in his general discussion of slopegraphs.

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.

[Original link is broken, the story is repeated here though – metatim 28/5/11]

[Okay, that link broke too, try this one – metatim 03/08/15]

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.

Things 97: Vertical Ship, Climbing Game, State of 3D

What is the oldest evidence of your own activity on the internet you can still provide a live link to now?

Last Week’s Puzzle
Last week I asked if it was true what they say, that 3D can never work. I think there are two compelling clues towards an answer here.

First, Box Office Quant takes a good solid look at what the money in 3D cinema is looking like. The conclusion is that after two years of 3D cinema being a serious consideration, it’s looking pretty solid. There’s lot of great data and visualisation of it over on the original post, but I’ll just reproduce the weekly revenues by dimension here:

It’s clear that something is working, anyway.

On the other hand, there was this development with Nintendo’s autostereoscopic 3DS by its producer Hideki Konno:

“We want to get software out to as many people as possible, and there are some people who just can’t see 3D […] We’re moving away from any stance that says if you don’t use the 3-D functionality you can’t play this game.”

While I’m yet to see some solid data, the picture that seems to be emerging is that a significant minority (10%?) really do have an issue with the convergence/focus conflict that Walter Merch identified (and which is, incidentally, the underlying science behind the apparent paradox highlighted in this XKCD), to the point that watching a full-length 3D movie or spending a significant time playing a 3D game is an uncomfortable experience for them. Naturally there’s also a small proportion of people that for various reasons do not perceive 3D in real life, for whom a 3D film/game has nothing to offer above a 2D one (and I suspect they are being used as a kind of smoke-screen to hide the bigger concerns about the former group in Hideki Konno’s quote above).

It seems that minority is small enough that 3D cinema revenue remains robust, but large enough that Nintendo don’t want to undermine their universal appeal by allowing 3D to be a barrier to participation.

Incidentally, I find it an incredible sign of the times that we now have three dimensional full-colour moving image experiences at a fully commercial scale, which is really quite an amazingly neat trick, and yet so many people I’ve spoken to seem to feel it’s not particularly worth having. Or in Louis CK’s words, “Everything is amazing right now, and nobody’s happy”:
