Is it safe to come out yet?

*Peers cautiously out from under rock*

I might give the A to Z challenge a go another year, but it is a big time commitment and I chose to spend it on things other than blogging. Even not taking part, the sheer volume of posts flooding my dashboard in April was overwhelming, so I visited a bit but mostly stayed out of the way.

Work is hectic and intense - not unmanageable, but certainly draining. Life outside of work brings the usual Spring activities getting things straightened out after the Winter months. In between the two, the logistics of after-school activities seem to get more challenging with each passing term.

Fortunately, I've still found time for artwork. The cover art for Tiamat's Nest is progressing well and I think I'm on the home stretch.

How was your April? Did you survive the A to Z?

I've been getting to grips with iDraw since I last posted about it in February.

I still reckon Visio is more suited to most uses at work. The big thing Visio has that iDraw hasn't is the concept of connections. Visio is all about shapes (boxes, circles etc.) and the connections between them. Move a box, and the linked connecting lines intelligently reposition themselves to preserve the links. Great for org. charts, mind maps, and technical diagrams.

iDraw doesn't do that. Everything is a "path" which you can edit but which remains separate from other objects on the page. Having said that, I'm finding iDraw far more powerful in respects that make it way more suited to my purposes at home.

iDraw makes it incredibly easy to draw irregular shapes using the line and pen tools, and to tinker with shapes you've already drawn. Visio is fairly limited here. A rectangle, for example, can be squeezed and stretched and rotated but remains stubbornly rectangular. Many times I've had to cobble together an overlapping collage of boxes in Visio to achieve an effect, but with iDraw, you can create highly complex shapes with ease. Many of the other tools, such as line and fill, also offer huge degrees of control and flexibility.

As well as being easier in many ways, there are things I can do in iDraw that I could never hope to achieve at all in Visio. More on that another time, maybe...

I've now got a few very different drawing projects on the go, including a star chart, architectural drawings, and mock-ups for a book cover. To give it a fair comparative road test, though, I tackled a project similar to something I'd already done successfully in Visio. Over Christmas, I drew a ship plan using Visio. This time I used iDraw to produce plans for another ship that will feature in the sequel to Ghosts of Innocence.

Conclusions: Because this type of drawing is mostly collections of simple lines, both tools are easy to use in broad terms. However, iDraw makes it easier to add curved elements, and I found it handy to separate parts of the drawing into layers for easier editing. I know I can achieve good results in both tools, but my preference now is firmly for iDraw.

Case closed. Happy camper.

How's your Easter weekend going? We are having a fabulous time. Warm sun, and the deck is now cleaned and the furniture brought up from winter storage.

The Da Vinci Cock-Up

I don't often post opinions on books or movies, and this post will probably illustrate why, but I feel the need to let off steam.

Last night, I finally got around to watching The Da Vinci Code. I know this movie has been hyped to death, which always I try keep from negatively affecting my views, but even so I found myself mystified and deeply disappointed.

First off, the movie was supposed to be a gripping roller-coaster action movie. Sorry, but no. I'm not a big movie-goer, but I'm sure I could quickly reel off a dozen or two recent movies that blow this out the water. In fact, practically every recent adventure that comes to mind did a better job of keeping me on the edge of my seat than this one. The Da Vinci code was tolerably OK in this department, but nothing more.

Secondly, and more importantly, I felt insulted as a viewer by overt and clumsy author manipulation.

Need to build audience sympathy? Cue one character orphaned in a car crash, and the other trapped down a well as a young boy. Sympathy engaged ... check!

The trouble is that both backstories were such blatant emotional plays and neither was especially relevant to the plot. Yes, you could argue that Sophie needed to be handed to the care of her fake grandfather, but then her real grandmother pitches up near the end, so where the heck was she all these years? There are countless less intrusive ways to achieve the same ends to mentor her.

The killer for me, though, was the countless points where characters behaved in unbelievable ways just to further the plot or introduce random tension. When the air traffic controller refused to co-operate with a senior police office to track dangerous fugitives because he was "on his break", my willingness to suspend disbelief crumbled and the rest was downhill from there. The author's hand manipulating the puppet strings was visible everywhere.

On the plus side, the underlying premise of historical subterfuge and the true nature of the Holy Grail was a gem. What a pity this brilliant concept got weighed down by clumsy author intrusions.

The lessons for writing? Respect your audience's intelligence, and respect the integrity of your characters.

Snowmobiles on water

At one point in Tiamat's Nest, Charles is on the run and his friend takes them across country on a ski-doo, or snowmobile. Along the way, they use it to cross a river a hundred meters wide.

One critiquer wondered if such a thing is possible. Yes it is!

I remember first seeing this trick years ago on a Top Gear program set in Iceland, before Jeremy Clarkson started getting in trouble with the BBC, and the memory returned when I was looking for obstacles to throw in Charles's path.

I thought maybe that this would be rare anomaly, but when I researched the possibilities in earnest I discovered that the feat is very well known and has even been turned into a sport!

So I am confident that what I wrote is a manageable, if rather dangerous, stunt.

Camping in Washington state and Oregon

This is a quick call for help! Does anyone know good campgrounds in the Washington/Oregon area? We're thinking of heading that way some time this summer, but this is unknown territory for us so I'm open to recommendations.

To give you a benchmark, this post from last year gives an idea of how we like to camp. Yes, it's camping for softies :) We like places that are well-equipped, clean, and with plenty of attractions nearby both on and off site.

After a furious burst of activity in February, Tiamat's Nest has finished its latest round of revisions and is now out to beta-readers.

No time for relaxing, though. I need to start work on ideas and drafts for cover art if I'm to get this puppy out there this summer as planned.

I've also been pottering around with iDraw. There's lots of capability there, and lots of things are very easy to accomplish that I'd have a harder time managing in Visio, but the software still shows some baffling and frustrating behavior even doing the simplest tasks. I clearly still have a lot to learn.

Emergent behavior

Another line of research...

Emergent behavior is at the heart of Tiamat's Nest on two distinct levels. Charles studies collective human behavior, where large groups act in ways that bear no resemblance to how individuals behave. And the complexity of the global network hides a nasty surprise.

So what is emergence?

It's what often happens when lots of things interact, usually following very simple rules. Things start happening on the collective level that were not designed into the individual units or the rules by which they act. Entirely unexpected behaviors and properties emerge, as if by magic.

This is best illustrated with a few examples

Temperature and pressure of a gas are properties of the gas as a whole, not of any one molecule. They are macro properties that emerge from lots of freely-moving molecules bouncing around. The most remarkable thing about the ideal gas law is that the same equation relates temperature and pressure to the amount of gas in a given volume regardless of what the gas is made up of.

The whole inexhaustible science of chemistry emerges from comparatively simple quantum-mechanical laws governing how electrons, protons, and neutrons interact. So do such diverse real-world effects as the conductivity of metals, the blue of the midday sky, the violence of nitroglycerin, and the beauty of snowflakes. None of these could easily be predicted just from looking at how subatomic particles behave.

These are all physical examples, but have you ever been part of a large group of people where you've felt swept along by events that don't seem to be wanted by any individual you speak to, but which take place relentlessly nonetheless? Mob behavior is notoriously and dangerously unpredictable. "The tragedy of the commons" is a self-destructive property of pretty much any group with a scarce resource. Stock market booms and busts are more complex behaviors of the market that are in nobody's interest, but which emerge from lots of simpler financial interactions.

Pretty much anywhere you have sufficiently large collections of units interacting in some way, you can expect some unexpected properties and behaviors to emerge.

Charles studies the emergent behaviors of large groups of people, but where does Tiamat come into the equation?

Have you ever been driving down the highway when you met a line of slow moving traffic? After a mile or two of crawling along, things speed up again with no obvious explanation for the hold-up. You've just been part of a pressure wave, very similar to a sound wave in air.

Waves, whether in molecules in air, atoms in a crystal, or cars in traffic, arise from the molecules, atoms, or cars following a very simple rule: don't get too close to your neighbor.

This illustrates another typical feature of emergence - properties emerge from the interactions, the rules, regardless of what the individual units consist of. One name for this is substrate independence.

This principle is important because some theories of the mind reckon that consciousness and intelligence are emergent properties of certain types of information processing networks. If that's true, then there should be nothing special about neurons themselves. They are simply the substrate enacting the rules. Another substrate, say a complex enough computer network that happens to embody the right kinds of rules, should therefore exhibit the same properties - whether we designed it or not.

Now that's scary!
