Things 110: Tom Cookie Monster Waits, Base Jumping with Dan Deacon, Nothing To Hide

Question – is change accelerating?
I’ve had vague qualms about the rhetoric of accelerating change, but intuitively felt that even if the arguments weren’t quite right, there was still some truth in it. Matt Edgar confronts these arguments directly here, noting among other things that Moore’s law is hardly a useful measure of change as experienced by humans, that the human perspective tends to see the present as faster-moving than the past, and that by some important measures, change has actually reduced:

There is one factor that is radically different today from any other time in history, and that is the size of the Earth’s human population […] one might argue that the global population boom is only made possible by stability in whole swathes of the world previously troubled by uncertainty and disruptive change.

So this week’s question: when we say “the pace of change is accelerating”, what exactly do we mean by that, and how can that be proved?

Another example of a cracking concept combined with an excellent execution (provided you’re already passingly familiar with the work of Tom Waits and the Cookie Monster):

The extraordinary API-linking service that acts like internet duct-tape, If This Then That (which I mentioned back in July when talking about how I find things on the internet) has now properly launched. They explain it pretty well on this aptly named page. One of the hardest things to do with IFTTT is work out what you should do with it, so rather brilliantly you can now see a list of the most popular tasks. (Personally I use it to cross-post my webcomic to Tumblr, email myself a reminder to do various things at the end of the month, and to add Twitter favourites to Read It Later).


Another video
That was technically a link I have shared earlier, so here’s something else: a rather nice video of people base jumping in some particularly ridiculous ways. However, the soundtrack gives the impression that they are striving to achieve something important for all of humanity, when in fact it’s pure, senseless, wonderful frivolity. As such, I recommend using a Dan Deacon soundtrack, which I conveniently provide for you below to play at the same time. (Dan Deacon is not to everyone’s taste though, so feel free to substitute your own flavour of insanely optimistic music).

For those that haven’t done this before: hit play and pause on both videos to get them streaming. Turn down the volume on the base jumpers to zero. Then when you’ve got enough streaming going on, hit play on both, and fullscreen the base jumpers.

Note that in terms of content, both videos take about a minute to kick off properly, so if you’re impatient then jump to ~50s into each one first.

There. Much better!


Quote

Very surprised I never came across this one from John Adams before:

“It is more important that innocence be protected than it is that guilt be punished, for guilt and crimes are so frequent in this world that they cannot all be punished. But if innocence itself is brought to the bar and condemned, perhaps to die, then the citizen will say, “whether I do good or whether I do evil is immaterial, for innocence itself is no protection,” and if such an idea as that were to take hold in the mind of the citizen that would be the end of security whatsoever.”

Rather satisfyingly (in a TV Tropes kind of way) this general idea is filed under Blackstone’s Formulation.


Last Week’s Question – Nothing to Hide?
Last week I asked for tweetable responses to the argument, “If you have nothing to hide then you have nothing to fear”, and got an impressive range of responses.

Xuan somewhat flippantly shot back:

“I have nothing to hide but a lot to lose so piss off Big Brother”

Simon says “nothing to hide” is wrong because it

“…presupposes that the reason someone desire[s] privacy is to conceal a wrong. What if people want privacy for other reasons?”

This is similar to my own thinking, which is essentially that privacy as a notion is a counterargument in itself. Hence my own answers along the lines of:

“If you have nothing to hide, why do you have curtains?”

“If you have nothing to hide, you’re not representative of the majority”

Richard pointed out that at the peak of the Wikileaks hubbub, this tweet did the rounds:

“Dear government: as you keep telling us, if you’ve done nothing wrong, you’ve got nothing to fear #wikileaks”

On a similar note, Rik points out that this is a good time to quote Juvenal:

“Who watches the watchmen?”

This neatly digs out the hidden assumption of “nothing to hide”, which is that the people you might hide something from can themselves be relied upon to act on that information “correctly” (whatever that may mean). However, this argument is a double-edged sword. The strongest reading (as I see it) is that the very idea of watchmen hides a kind of Gödelian paradox (after all, who would watch the people watching the watchmen?). But if you interpret it more simply it suggests that the answer to bad surveillance is good surveillance.

Or put another way: it seems to suggest that problems with surveillance can be solved by adding more surveillance. Given that surveillance already has that feedback loop baked-in (if crimes take place out of sight of CCTV then naturally you solve this by having more CCTV), this counterargument might not actually help.

A more direct line of attack might be to use extreme examples of Watchmen we may not feel comfortable about, for which I suggest:

“In Orwell’s 1984, should Winston Smith have anything to fear from Big Brother?”

“Would you still have nothing to hide if an extremist party formed part of the ruling coalition?”

Finally, Adam has a different approach:

“Given enough information I can make anyone look guilty”

An idea we’ve seen in various political and journalistic thrillers is that everyone has something that you could expose to damage their reputation, but Adam’s argument takes this a step further. This also confronts the above mentioned feedback loop of increasing surveillance head-on. As Adam says:

As […] data on each person grows, so too does the scope for misuse, misinterpretion and misidentity. […] No individual fact could be incorrect, but they could be formed into a picture that is, as it is known that people look for facts that meet their beliefs, and with enough information this could be achieved an alarmingly high proportion of the time…

That’s my favourite answer so far, although it does need people to buy into some form of Blackstone’s formulation (see above John Adams quote). This will be an argument to refer back to over the coming years I suspect.

There’s much more to say on this, but that will have to wait for another blog post.

Things 60: The Box, Vans, and the Shower Problem

(Originally sent October 2009)

Films
I saw Triangle, and although it may need a second viewing to clarify, I think it might be the best constructed time-bender I’ve seen yet.

I also saw The Imaginarium of Doctor Parnassus, and as expected it was very nice to see what Terry Gilliam can do with modern CG and a decent budget, but it did suffer from the apparent absence of a clear narrative arc, hampered further by the marketing’s misleading emphasis on the character played by Ledger ( / Depp / Farrell / Law).

Video
Richard “Donnie Darko” Kelly’s latest film, The Box, looks like a hilariously insane extrapolation of a very simple temptation story.

Here is a decently executed, 7-minute version of the basic idea called “Black Button”:

Even that felt fairly stretched, so who knows what they do to drag it out to 115 minutes in The Box. You can get some idea of how silly they go from the trailer:

It would have been cooler as a van”, a nice Threadless T-shirt design that doubles as a puzzle. How many can you identify?

Last Week’s Puzzle: The Return Ticket
Just in case you forgot, last week’s puzzle was this:

“Trains leaving station A only go to station B. A single from A to B costs £3. A return from A to B and back again costs £5. A woman walks into train station A for the first time in her life. She goes up to the counter and hands the cashier £5. Without either of them saying a word she is given a return ticket and leaves happy. How did the cashier know what she wanted?”

Since it took me 5 years to work out, I’m hardly about to reveal the answer here. However, I will say the following:

a) I now know a few people that have solved it in under a minute

b) While there are naturally many possible answers, there is one answer that is clearly better than the others

This Week’s Puzzle: Showers
While some are lucky enough to have a shower sufficiently advanced to have solved this problem with the magic of modern technology, for those of us less fortunate, the problem remains:

a) Why is it so hard to get a shower to run at a comfortable temperature?

b) What can be done about it?

Eddie Izzard explains the problem more dramatically here:

Things 59: Building Projection, Plant Sculpture, and the Train Problem

(Originally sent October 2009)

Films
I saw Surrogates, which was a strong enough concept (with relevance to the kind of changes we will see in the coming decades, even if we don’t quite achieve fully robotic avatars affordable by 98% of the population) that it maintained interest despite the weak writing and characters.

Technology unlocks surprising things. Witness the kind of trompe l’oeil magic that can now be achieved by virtue of having a powerful enough digital projector:

Highlighted in the final part of last week’s issue of The Week, this article from pseudonymous postman Roy Mayall casts an interesting light on the current wrangling with Royal Mail.

Key quote from towards the end:

“There is a tension between the Royal Mail as a profit-making business and the Royal Mail as a public service. For most of the Royal Mail management … it is the first. To the delivery officer … it is more than likely the second.”

The current ongoing (in)action would seem to stem directly from this tension.

Pictures
Sculpture/carpentry/architecture with living plants.

I suspect this would seem less benign if the same modificiations to a natural form could be carried out within minutes instead of over the course of years.

Puzzle
I mentioned this puzzle in a recent discussion stemming from Things and it sparked a lot of interest. Here is a version only slightly modified from the way I originally heard it from Laurence:

Trains leaving station A only go to station B. A single from A to B costs £3. A return from A to B and back again costs £5. A woman walks into train station A for the first time in her life. She goes up to the counter and hands the cashier £5. Without either of them saying a word she is given a return ticket and leaves happy. How did the cashier know what she wanted?

The original version, along with many other puzzles, can be found here:

(Note that I think this puzzle should now be filed in the first section).

Things 109: Jonathan’s Card, Dr Who Cats, Mix Shift Visualisation

Question – Nothing to Hide
As technology makes surveillance of many kinds ever easier, some people  are worried about Big Brother, two words which conveniently encompass the general idea that this would be bad, via Orwell’s 1984, which incidentally is one of those classics that you really should read if you haven’t yet as it is only becoming more relevant.

In response to this, others say “If you have nothing to hide, then you have nothing to fear,” which is powerfully concise rebuttal to these vague fears.

I can think of some counterarguments to that, but they tend to be long, and as noted by The Brads, something that takes more than 140 characters to explain doesn’t generally spread. So: this week’s challenge is to come up with a counterargument for “nothing to hide” that is 140 characters long or fewer.

A while ago, as an experiment, Jonathan Stark made his Starbucks card details public, so anyone could add credit and anyone could spend that credit. His page explaining this is here. (Note the caveat at the top – this no longer works).

Sam Odio found an easy way to transfer credit to his own Starbucks card, and I recommend reading his take on the idea (and his exploit) here.

If you don’t have time for that, you could just read this summary of the whole story over at Good, which lays out the whole strange tale.

Pure internet linkbait, but with an execution this good, it deserves to be: Dr Who cats.

Previous Puzzle
Last time I asked for ways to visualise data in such a way that mix shifts affecting conversion rate would be readily apparent.

Adam naturally had a full consultant’s answer, explaining how he would show the data different ways depending on the audience (sales director, website content manager, SEO manager…), and how he might talk through the component parts of the change in a sequence of slides, which is all very sensible. However, what I really want is something that I as an analyst can look at to apprehend the whole situation, ideally in a generic way, so any given shift becomes clear.

Simon described an interesting single-view answer, but in preparing this post I realised I needed to confirm some of its details with him, so that will have to wait for a later edition of Things.

On to my answer… the data set was as follows:

[before mix shift | after mix shift]:

Banjo section visits [10,000 | 20,000] – lots more traffic
Banjo section sales [100 | 220]
Banjo section conversion [1.0% | 1.1%] – conversion increases!

Gun section visits [1,000 | 1,000] – same traffic as ever
Gun section sales [100 | 110]
Gun section conversion [10% | 11%] – conversion increases!

Overall conversion before:
(100 + 100) / (10,000 + 1,000) = 1.82%
Overall conversion after:
(220 + 110) / (20,000 + 1,000) = 1.57% – overall conversion has decreased!

My solution looks like this:

This shows how the total visits and orders (black lines) are composed of the individual sections (red/gun and blue/banjo). While both the blue and red arrows get steeper (representing improved conversion, although it’s hard to see this on the red arrow), the angle of the black line decreases (representing the overall decrease in conversion), since the blue arrow became so much longer.

This pretty much works for the extreme example given. However, it has significant weaknesses as a general solution:

  • It doesn’t work as a trended view – conceivably it could be animated, but that seems like overkill
  • It’s hard to compare the angle of arrows when traffic changes significantly, as in the gun section above
  • It tends to encode all the interesting information into a narrow diagonal band of the chart.

Further improvements are of course welcome!
