Then read this article by PZ Myers. Myers is a well-known scientist, blogger, and anti-creationism commentator.

"I went to attend a screening of the creationist propaganda movie, Expelled, a few minutes ago. Well, I tried ... but I was Expelled! It was kind of weird -- I was standing in line, hadn't even gotten to the point where I had to sign in and show ID, and a policeman pulled me out of line and told me I could not go in. I asked why, of course, and he said that a producer of the film had specifically instructed him that I was not to be allowed to attend. The officer also told me that if I tried to go in, I would be arrested. I assured him that I wasn't going to cause any trouble."

The punchline is that his friend was allowed in to see the film. The friend was...Richard Dawkins.

So what does the video have in common with that story? They both show the problem with relying too heavily on blacklists. If you focus exclusively on one thing, you will miss whatever else may be right under your nose. (Think: old-fashioned spam filters, terrorist watch lists, screening for dangerous liquids on planes, etc.)

Because I haven't read the Steven Gould book the film is based on, I'm just going to take it on its own merits. First of all, the film is a traditional wish-fulfilment fantasy: ordinary boy discovers he has a secret ability, and discovers that because of this secret, dark powers are ranged against him. Adventures ensue, during which he gains mastery of his ability, and uses it to defeat his enemies.

Executed well, this is a great, classic plot, and Jumper does a very good job with it. Hayden Christensen (who plays David) often comes across as bland and monotone, in a handsome way, but in this serves the film well: it emphasizes David's essential ordinariness, apart from his ability to jump. He doesn't know kung-fu. He doesn't dress up in a costume and fight evil. He uses his powers to make his life lush and easy, not to better mankind. So when he first encounters the bad guys (Samuel L. Jackson & co.), he is totally outmatched.

This is where the other jumper, Griffin, comes in. Griffin (played brilliantly by Jamie Bell) is a fast-talking, bitter, and somewhat unhinged young man who has been running from the Paladins, and fighting back, all his life. He is the archetypal mentor in the story, with the twist that he sees David as more of a threat than a student. He doesn't want David upsetting all his plans and jeopardising his carefully hidden base. He is by far the more interesting of the two, but the needs of the plot dictates that he is relegated to the role of edgy, antagonistic ally. (At least they decided not to make him "wise-cracking", too.) Still, because he doesn't die (ah, damn it, spoiler), the door is open for him to play a more important part in the sequel.

Which brings me to OMG HOW BLATENTLY OPEN-ENDED CAN A FILM GET?? Fully the last fifteen minutes are spent carefully not resolving plot lines and setting up the pieces for Jumper 2. Which, given its box office so far, is a near certainty. Really, you could even see it as a pilot for a TV series than a stand-alone film.

But still...I liked it. It reminded me a lot of The Bourne Identity, also directed by Doug Liman. Just like Jason Bourne, David Rice has to rely on his own abilities instead of the gadgets and resources of some powerful agency. Both characters are hunted outcasts, gradually fighting their way inwards to the core of a conspiracy. (Even the soundtrack for Jumper has overtones of Bourne - the main theme sounds an awful lot like Moby's Extreme Ways.) This is what it comes down to for me: it's a good hero story. I'm just a sucker for those.

So what were the significant technological additions to my life in 2007?

• New 80GB iPod (5G). My old one was a 20GB model, and it wasn't enough to hold my entire music collection. Now that I work mostly from home, I don't use the iPod nearly as much as I used to, though, and I have hardly watched any video on it at all. Mostly I use it to shuttle music around the house: we have a few sets of small portable speakers, and I plug the iPod in whenever I want some music in the kitchen or the bathroom. The bad: I have found this new iPod to be slower and more prone to crashing than the old one.
• MacBook Pro (15", Core Duo 2): sleek and gorgeous, it is one of the finest pieces of computing machinery I have ever used. (It's a work laptop, so it's not really a personal addition. But it's a major feature on my desk and in my life, so I'm going to count it anyway.) The MBP is light and fast, and I have grown to love being able to pick it up easily and use it away from my desk. Travelling with it is great, too, apart from the way it picks up a charge when going through airport security--I regularly get a shock when I pick it up after it has gone through the scanner.
• Crumpler Cheesy Disco bag: a good laptop deserves a good bag. The Cheesy Disco comfortably holds the MBP and accessories, as well as a book or two, papers, and all the other rubbish I carry with me. It's too big for everyday use when all I need with me is a book, a pen, and my wallet, but it's great for big trips.
• Griffin Elevator notebook stand: it brings the MBP's screen up to the same level as my main screen, which is a practical necessity for avoiding neck strain. Also, it gives me space underneath the MBP to put more desk clutter.
• Samsung SyncMaster 2032BW 20" monitor: It's a good enough monitor, but not a great one. Compared to my Dell Ultrasharp, the colours are harsh and vary slightly (but noticeably) from top to bottom, the viewing angle is poor, and it lacks an ergonomic stand for changing its height or tilt. Still, it was cheap, and it gives me a THIRD MONITOR, which was reason enough for buying it. I used to be a multi-monitor skeptic, but I'm fully cured now.
• Wacom Bamboo graphics tablet: this was a toy buy, because I had never tried a tablet before, and I just wanted one. I'm not much of an artist, but it does make fine work in Photoshop much easier and more natural. Also, it combines really well with Google SketchUp for drawing 3D models.
• HP C5180 all-in-one printer/scanner/copier: It's not as good a printer as our old printer, but cartridges are ahout half the price. It's not as good a scanner as our standalone Epson Perfection, but it doesn't take up any extra space on the desk. Being able to run off quick photocopies instead of scanning and printing is a big plus, and plugging it straight into our network with an ethernet connection instead of attaching it to an always-on computer is an even bigger plus. Overall: yay. But I will need to keep the old scanner around for occasional dedicated photo work.
• Playstation 3. Okay, not strictly mine; it was Abi's Christmas present. But it means that we now have a full complement of current-generation consoles around the house.
• Roland TD-3 drum kit: total sweetness. I love playing the drums, but--to my detriment--sometimes I forget about that. For a clumsy and performance-shy amateur like me, the best feature of an electronic kit like this one is the ability to plug my iPod into the brain's external input, and then be able to play along through a set of headphones.

There are a also a couple of software services that are worth mentioning. They're not strictly gadgets, but I think they fit here anyway:

• Mozy off-site backup. I have rotten luck with hard drives. Mozy ensures that I don't have to worry about data loss any more. The initial upload takes a long time, but after that the daily run is painless. I still keep local backups for fast recovery, but I don't feel like I have to be obsessive about them.
• Jungle Disk. Jungle Disk is a remote storage system that uses Amazon S3 for its back-end. You can use it as a backup system like Mozy, but unlike Mozy it also gives you filesystem-level integration. This means you can map a drive to your off-site space. This is great for sharing files between different computers, and also between different people.

I'm trying to think now if there are any gadgets on the horizon in 2008. No new games consoles, unless we go retro and splash out on a Sega Mega Drive or something (not inconceivable). The biggie for which I'm going to have to put on my best puppy-dog eyes will be a new big-screen TV when we move house.

Actually, wait--we're going to be buying a new house soon. Does a house count?

In hindsight, this is a very odd book. However, it's not at all odd while you're reading it. In fact, for most of its length, it races along like a present-day spy thriller. It starts with a nuclear explosion at RAF Leuchars, and then rolls on with a series of explosions at major UK industrial installations.

Were they terror attacks? Opening shots in a global conflict? Peace campaigner Roisin Travis is covertly taking photos of the RAF base when she sees a strange device being unloaded. Just then, she gets a text from her brother Alec, who is serving in the military in Kurdistan, warning her to leave immediately. She manages to escape the blast, and goes on the run, fearful that the security services will think she had something to do with it. Her father, James Travis, appears to be a standard software contractor, but is actually a covert agent for the French government. He, too, receives an alert message, and goes on the run.

At this point, the chase is on, against a backdrop of global fear and escalating international tension. The UK security services stage a hunt for Roisin and James. An American agency goes to work spreading disinformation about the incidents, while conspiracy web site owner Mark Dark tries to filter out the "real" truth about the device that Roisin saw.

The book covers a lot of the same themes as Charles Stross does in Halting State: the surveillance society, intelligence operations in a highly networked world, and a fundamental uncertainty about who your actual enemy is. Along the way, there are only small hints that give away that the story is science fiction. Although you could easily read it as being set in present-day Britain, it takes place in a slightly altered timeline--one where Al Gore won the 2000 presidential election, but where the 9/11 attacks still happened, and the world still went up in the flames of war. Also, there are nuggets of cosmological speculation that you probably wouldn't see in a mainstream thriller, as well as the suggestion that some of the conspiracy theories about flying saucers and death rays might actually be real.

But you don't get the full science-fictional pay-off until right at the very end. Like, in the last eight pages. And this is what makes the book so odd. It ends with an enormous revelation...and a political joke. It's almost like one of Asimov's short stories that ends with a terrible pun. All of the hard-boiled personal tension and international brinkmanship, is rendered nearly obsolete when MacLeod zooms out and shows you the bigger picture.

That's not to say that the ending is bad; it's just unexpected. When I finally closed the cover (after staying up to 2am to finish it), part of me went "aargh" and wanted to throw the book down in disgust at the sharp left turn, while another part went "wow" and marvelled at the sense of wonder the ending provokes. And now, a week or so later, I still have mixed feelings. But I think that the power of surprise will ensure that The Execution Channel will stick with me for longer than if it had had a conventional linear climax.
