Things 77, Time Slices, Innovative Pricing, Trigger’s Broom

Video
Imagine frames of a video printed on the side of a sequence of decks of cards. Then imagine all of those decks combined with a perfect n-riffle shuffle. What would the result look like if played back as a video? Something like this:

I love the idea that seemingly obvious things that work pretty well are actually only local maxima, and if you move far away enough from the norm you can actually find something far more effective.

The nicest example of this I’ve come across so far can be found here; some great data to show that under some circumstances combining the two pricing strategies of pay-what-you want with half-goes-to-charity produces a significantly better outcome than either option alone, or standard pricing. (This was anecdotally demonstrated by the Humble Indie Bundle back in May, but that clearly lacked a fair “control” for comparison).

Puzzle
As suggested by Angela last week, the problem of Trigger’s Broom, more conventionally known as the Ship of Theseus Paradox:

Trigger: And that’s what I’ve done. Maintained it for 20 years. This old broom’s had 17 new heads and 14 new handles in its time.
Sid: How the hell can it be the same bloody broom then?

Is Trigger’s broom still the same broom? If so why, if not why not?

Things 76: Bikes, Polaroids, Kanye Tweets

Video
For some reason it’s the most pointless things that make me feel most encouraged about the human race:

I am naturally drawn to extremely long term, incremental projects. This probably explains why I have chosen to serialise 50+ issues of old Things on this blog at a rate of one a week; why I have spreadsheets tracking my sleep data going back nearly 10 years; and perhaps why it took me 6 years to complete a PhD. But as the title suggests, “He Took a Polaroid a Day” takes that kind of thing to a whole new level.

Last Week’s Puzzle
Last week I asked why buses come in clusters. I think the main problem is the feedback loops – any traffic fluctuation that causes a bus to become slightly delayed means a longer wait at the next bus stop, which means more people are likely to turn up. More people take longer to get on board, and as Xuan points out make it more likely the bus will need to stop more often. Meanwhile, when the next bus turns up there has been less of a wait since the last bus left, so fewer people board, and by the same token the bus can make faster progress, so the gap between buses is closed by feedback loops at both ends.

One answer is to hold buses to “even out gaps in the service” as does indeed sometimes happen. Xuan also suggests better data on how crowded imminent buses are would encourage people to wait for the next, more empty bus, easing the feedback loop. I also think the surfacing of real time public transport data – as could be viewed a few weeks ago – will help us collectively improve efficiency in a similar way.

Things 75: Fast robots, Inception links, Buses

Video
It’s strangely easy to forget that sufficiently well-made robots can move and react ridiculously fast. Here’s some nice reminders:

Spoiler warning: if you haven’t seen Inception, these links are not for you. Move along to the quote.

I saw Inception and particularly liked the way you can enjoy it at face value or try to make out a deeper underlying truth. Whichever camp you fall into, I recommend checking out this YouTube video (more accurately audio), and if you’re trying to piece things together you might be aided by this simple diagram, or this more ambitious one.

If you want to dive deeper into working things out, I recommend you start with the IMDb FAQ which has some pretty good answers, then move on to the InceptionTheories forum.

Here’s a classic: why do buses come clusters?

Last Week’s Puzzle
Last week I asked why walk-in freezers have doors that cannot be opened from inside. As Richard pointed out, the answer is that actually, they generally don’t. But if they did, I like Maria’s theory: “Maybe it is a Hollywood conspiracy. Think of the lack of plots if people didn’t get stuck inside a walk-in freezer.” Hollywood manipulating real life to make convenient tropes seem more plausible sounds like a fun premise for a film…

Things 74: Swing, Freezer Door, Carnist Bingo

Link
A test audience on Facebook didn’t find this remotely as incredible as I did, but here it is anyway: The Swinger, an algorithmic process that can automatically generate a swing remix of a song.I recommend trying out whichever of the songs listed you are most familiar with, but for me “Money For Nothing” had the most profound effect.

Puzzle
Anyone that has watched enough movies or TV is familiar with the dangers of an industrial freezer room: if you happen to get shut inside, you are doomed, since the door can only be opened from outside. But this seems like a very strange design flaw. Why are those doors designed in such a way?

As a vegetarian, I’ve found myself in many minor debates on food ethics over the years. A strange feature of these debates is that meat eaters have not generally applied as much thought to what they personally think they should or should not eat, and as a result vegetarians (and especially vegans) tend to find themselves arguing against the same instinctive, poorly-thought-out arguments every time. The Secret Society of Vegans found an excellent answer to this recurring feature of any v*gan’s life: a ‘bingo’ card for use during such debates:

Last Week’s Puzzle
Last week I asked how turning over a cassette caused the other side of the tape to be read. In fact the ‘side’ terminology only applies to the cassette – the tape itself has one ‘side’ of music recorded in one direction along the top, and the other in the opposite direction along the bottom.

Tarim points out that 8-track tape is much more mind-boggling: the tape is a continuous loop, wrapped around a single spool, with one end necessarily being pulled out from the inner part of the spiral. How could such a mechanism overcome so much friction in order to run continuously?
