In The Trial and The Castle, novels by Franz Kafka, the protagonists confront institutions that are inscrutable, complex and seemingly omnipotent. And within these institutions, a “power law of terror” is at work – at each layer of the institution the terror levels increase exponentially, as expressed by this allegoric doorman in The Trial:

I am powerful. And I am only the lowest door-keeper. But from room to room stand door-keepers each more powerful than the last. The mere aspect of the third is more than even I can bear.

Of course, this “power law of terror” shouldn’t be confused with Bruce Schneier’s Power Law of Terrorism.

Today was the day of the Asics 10K London Run, the first serious running event I’ve ever taken part in. And I finished the race alive, getting to the finish line in just over 54 minutes!

But what’s more impressive is that my sponsors helped me raise a total of £290 – much more than my goal of £200. That money will go to the Haller Foundation, a charity that works towards environmental and economic development in Kenya. It’s not too late to sponsor me, of course – just head over to my page on JustGiving.com if you’d like to chip in.

The race itself

My usual running routine is pretty simple. I run up to Highbury Fields, circle it several times, then come back home. Other runners will be there but it’s hardly packed. So the 20,000 participants in today’s run made it a very different experience.

There were lots of novel things about today’s experience. Here are three of them.

To begin with, it was funny being a cause of, rather than merely subject to, a massive transport disruption in central London. As soon as I arrived at Piccadilly and saw the thousands of runners mobbing the cordoned-off streets, I realised that the race had more or less shut down Westminster for the morning. Usually when these things happen I’m one of the people on a diverted bus cursing the event and everyone involved, so it was nice for the boot to be on the other foot.

Another thing that surprised me was how encouraging I found the spectators. I’m accustomed to running in a near-deserted field so wasn’t looking forward to thousands of strangers looking on and shouting. But in the end I actually missed them on the stretches of race where they weren’t allowed. Hopefully it won’t seem too lonely next time I run around Highbury Fields!

Finally there was the sheer size of the crowd. On Highbury Fields you might pass an unpredictable dog or a pavement-spanning pushchair armada, but at least there aren’t 20,000 other people running around. When there are, you quickly learn two things: i) there are lots of people slower than you and ii) there are lots of people faster than you. This means you need to read the crowd, in front as well as behind you. Running into someone’s back or being run into by someone else could lead to a pretty painful fall, so you really have to look out.

Cathy came along to cheer me on, and found it so inspiring that she went to the gym afterwards and ran 5km on the treadmill for the first time ever. And I was pretty inspired too. I will definitely be doing it again!

Do you need to quickly find the differences between two large Word documents? Have you edited a large document only to realise you didn’t have Track Changes turned on?

The “Compare” feature in Word 2007 will find the differences between two documents and display them using the Track Changes view. Here’s how to use it…

Firstly, click the Compare button under Review. Then select the first of the two options.

You’ll then see something like this:

Click on the little folder icons next to the dropdown menus, then choose both the original document and the one you changed. It doesn’t matter which order you do it in.

When you have selected both your documents, the box titled “Label changes with” will become editable. If you type your initials here, changes will be attributed to you.

Then click OK and everything will change dramatically. You’ll see a panel on the left hand of the screen summarising the changes, and two panels on the right showing both the documents you selected:

But the exciting stuff should be in the big middle panel, which is titled “Compared document”. There, you should see precisely what would have happened if you’d been using Track Changes all along!

Stuff you added should be in red text and stuff you deleted should be crossed out. If you hold your mouse over any of the red text you should see a note about the change too.

Using the “X” buttons in the top-right of each panel, close all of the panels except “Compared document”. You will now simply be viewing the “track changes” document, so you can just save it and send it over. And that should be it! Just remember to turn on Track Changes if you have any more editing to do.
