Things 52: Pug Baroo, Location Based Services, Argument Visualisation

(Originally sent June 2009)

Last week, Things was once again postponed due to time pressures burning my midnight oil candles at both ends. However, now that both my IDM evening course and my PhD are over, I theoretically have more time, and I’ve also made progress with my answer to the puzzle from Things 46 on how to get things done at sub-weekly intervals (see puzzles section below), so future updates may return to regularity.

Films
I finally caught Synecdoche, New York. Imagine Charlie Kaufman (Being John Malkovich, Eternal Sunshine of the Spotless Mind) doing a ‘Memento Mori‘ piece. It’s like that. I think it’s the best film I’ve seen since Speed Racer, which is a statement almost entirely devoid of utility or cogency.


Video
It’s been quite a while since I featured a ‘cute animal’ video. Here’s three pug puppies demonstrating the comedic value of turning your head on one side when confused, an action which, as I understand it, is referred to as ‘baroo’ in cute animal watching circles.

Link
Location based services – most commonly applications on your mobile that help you do things by knowing where you are through GPS or mobile phone mast signal interpolation – are on their way. (In terms of the hype cycle I think they are currently falling from the ‘peak of inflated expectation’ to the ‘trough of disillusionment’ before finding genuine utility). Mathew Honan tested a bunch of these services and wrote about it in Wired, in a long but important article.

My personal take is that most of the services he tries are like MySpace in that they work okay when the only other people on there are People Like You, but in order to scale they will need Facebook-like privacy control. (Specifically more like the new controls Facebook are adding to the publisher, and I also suspect a time window would be added – e.g. Share my live location with these people, for the next 8 hours only).


Quote
I like to think the years I spent in higher education were successful by this rubric:

“Nothing you learn in the course of your studies will be of the slightest possible use to you in later life – save only this: that if you work hard and intelligently, you should be able to detect when a man is talking rot. And that, in my view, is the main, if not the sole purpose of education.”  – John Alexander Smith


Picture
I’m interested in creating useful visual representations of arguments, as I feel sure there is a good way to do it, but I haven’t seen one yet. (I’m currently working on an idea for one which will appear in Things when I have a first draft).

Here’s a version for the same-sex marriage debate by Patrick Farley, based on observed debates on Facebook, which is pretty good (click for big):


This week’s puzzle
As the number of people on the CC list for Things has grown, the amount of reply-to-all discussion seems to have decreased. Currently there are 11 people on it, including me.

It seems clear that some threshold has been passed and a CC list discussion really works best with around 5 people.

The puzzle is, how should this be resolved? For example, I could create one CC list for the first 5 people that were on it, and another for the rest. Or I could create one CC list for people from RAPP, and another for everyone else.

Both of these solutions have disadvantages. What do you think?

On a related note, how do you think I should credit people’s answers to each Week’s puzzles? (In the example below, I summarise the answers people gave that matched my own thinking, and cite by first name the answer I hadn’t considered).

Puzzle from Things 46
I asked for good ways to develop routines with time periods somewhere between daily and weekly. My answer was a spreadsheet programmed with the intended goals and frequencies and set to load up when I switch on my PC.

After trying this out for a few weeks it seems to be successful, and I’ve uploaded a demo version. For a given task, a given ‘davelength’ (a portmanteau of ‘day’ and ‘wavelength’, setting the intended number of days I want to elapse between instances of the task), and a weighting factor, the spreadsheet highlights if I am due to do any tasks today, and if so, which one to prioritise. Upon completing the task I just have to enter the current date in the ‘Date last done’ field.

It would probably work well as an iPhone app, which means someone has probably done it already.

Last week’s puzzle
Reasons people prefer reading writing on paper than a screen seem to breakdown in to 3 main categories:

1) Visual. Resolution and emissivity of screens are issues. In principle technology should be able to overcome these concerns.
2) Convenience. A piece of paper can be folded and put in a pocket, annotated, pinned to a wall, doesn’t need electricity, and is easily carried around to read in many situations. But once again, technology could theoretically match this in most regards, and exceed it in others – think adjustable font size, editing rather than crossing out, digital annotations (including a social aspect), searchable text, and backed up data, for a start.
3) Cultural Inertia. Even if technology addresses other concerns, people that have grown up reading from paper will be resistant to change. The added convenience factors mentioned above will have to be significant before a real transition can take place. (Thanks to Laurence for pointing out this one).

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 47: Flying Robot Penguins, Hamster Wheel Projection, Space Stick

(Originally sent May 2009)

Film
I saw Wolverine. I found it to be acceptable. I was particularly impressed that they held almost all shots of the enjoyably over-the-top climactic battle back from the trailer.

Video
In this video there are giant flying robot penguins, after the small swimming robot penguins, after the pre-roll ad, after the video loads. But worth the wait.

Link
Since the media make it very difficult to tell if a manageable disease outbreak has grown into a rampant society-threatening pandemic of doom, here’s a map that collects data on the progress of Swine Flue cases.

Semiotically speaking, the size of the circles when zoomed out subconsciously suggests a more severe situation than is actually the case, but zooming in quickly brings things into perspective.

Quotes
Going through my old archive of things-I-heard-people-say-and-wrote-down recently, I found a cluster of baffling utterances all made by the same individual, who shall remain nickless. Er, I mean nameless.

“I’ll take your word for it – but I’m still not convinced.”

“Is it one of those things you can only see when you look at it?”

“I don’t like shopping, it’s really boring. Except when you’re buying something for yourself… or someone else.”

I’ve come across this three times this week, but feel compelled to add to its viral propagation. Here and There is a “horizonless projection” map of Manhattan, which some have more intuitively described as a “hamster wheel projection”.

Previous Puzzle – The Inconvenient Hobby

Last time I asked for a time-based goal that can easily become part of a routine but sits somewhere between once-a-day and once-a-week. Given some of the answers, it became clear I hadn’t emphasised the ‘easy’ part sufficiently!

One answer was to tie different aspects of the same goal to different days of the week For example, if the goal is to exercise 3 times a week then one could do three activities once a week each, assigning each one to a particular day of the week.

My own answer has been to create a spreadsheet which automatically pops up when I boot up my PC and tells me how many days have elapsed since I last did the six things I’m trying to do with non-trivial frequencies, and whether that exceeds my target number of days to elapse for each one. Or at least, that will be my solution, but I haven’t got around to implementing it yet, which perhaps speaks to a greater problem.

Puzzle – the Space Stick
Information cannot travel faster than the speed of light. If it did, you just need to apply a bit of special relativity (not even general relativity) and you quickly get paradoxes. There’s a deeper argument to be made there, but trust me, if information could travel faster than the speed of light, It Would Be Bad, in the Ghostbustersian sense.

(Side note: that link was an example of something Kevin Kelly has spoken about – bringing the tools we have for literacy (cut and paste, footnoting, referencing) to moving pictures. Unfortunately the audio is very quiet on the YouTube video I linked to so it probably doesn’t quite work, but it’s close. See http://kk.org/ct2/2008/06/tools-for-vizuality.php )

[We now see further problems interfering as the video has been taken down. It linked to the utterance of the phrase “that would be bad” in Ghostbusters. – T.M. 30/4/11]

Unfortunately this important speed limit on information transfer seems to break if you have an extremely long stick.

It’s difficult to state the problem both precisely and concisely, but here we go:

Imagine you are at one point in space and your friend is one light-year away. You are about to have a baby and your friend will want to know if it is a boy or a girl as soon as possible. If you were to send this message at the speed of light, which is incredibly fast, it would still take one year for the message to reach them, since you are one light-year apart.

Anticipating this issue, you have got hold of a Space Stick, which is one light-year long and as rigid and low-mass as a substance can possibly be. With the Space Stick spanning the distance between you and your friend, you arrange for it to sit above a button that activates a buzzer at their end, the idea being that you simply press on your end of the Space Stick and the button is pressed pretty much instantaneously.

With a pre-arranged code (tap for a boy, long press for a girl) it seems as if this could be used to transmit information faster than light. Why could it never work?

Things 46: Miniatur Wunderland, Map of Remoteness, Door Considerations

(Originally sent April 2009)

Video
Brought to my attention by Richard, the official corporate video of ‘Miniatur Wunderland’, the largest model railway in the world, complete with earnest German-accented voice-over:

Link
An article on New Scientist with some great images showing the extent of rail, road and river networks across the globe, and the resultant ‘remoteness’ score for any given location.

Quote
I’ve mentioned this quote in conversation about three times in the last two weeks so it’s evidently topical:

Don Marquis: “The chief obstacle to the progress of the human race is the human race”

Puzzle
Last week I asked why front doors open outwards. If there can be said to be one true ‘reason’, it is that there are many reasons for it to be this way round and only one for it to be the other:

– Practicality. A common situation is for one person to be opening the door for another from the inside. It’s safer to have it open towards the person doing the opening.

– Security. If the hinges are on the outside they are more easily removed. It’s cheaper to have the door open inwards if you want to have the hinges inside.

– Weather. The hinges (see above) and interior of the door will tend to be less exposed to the elements if the door opens inwards.

– Defensibility. It’s easier (that is to say, actually possible) to defend against a potential intruder by barricading a door that opens inwards.

The only reason I’ve heard for going the other way is for safety in case of a panic evacuation, where people are likely to be pushing against whoever is first to the door. This trumps the other reasons when it comes to large public venues, but is not significant in an ordinary home.

This week’s puzzle
A great way to motivate oneself to do something (such as housework or a hobby, say) is to set an achievable time-based goal that can easily become part of a routine, like doing it once a day, or once a week. For example, I frequently intend to start a draw-once-a-day routine, and send Things almost weekly; others have similar goals for photography, or blogging.

The problem is, there’s a ridiculously huge difference between ‘every day’ and ‘once a week’. What possible strategy could one use that is somewhere between these two extremes?

Picture
It’s not explained very well, but apparently the European Space Agency’s “Environmental Satellite” can use radar to detect changes in the Earth’s surface with millimetre accuracy. In this way, images from before and after the recent L’Aquila earthquake in Italy can be compared to track how the ground has been shifted. It’s a pretty fascinating visualisation.
