CamVine is hiring!

Aha! You know things are really getting serious at CamVine now… we’ve just created an ‘Opportunities‘ page! Keep your eye on it!

The first post we want to fill needs somebody who really understands web applications and enjoys creating them, and who has excellent all-round software skills and IT interests.

I’ve been doing much of this development in the past, but I now have to concentrate on other things, so somebody else gets to do the fun stuff. Besides, we now need somebody really good!

Could this be you? More info here.

Freedom of speech and IP addresses in India

A man in Bangalore was arrested and put in prison because he posted some disrespectful pictures of an Indian national hero on Orkut. This particular hero died over three centuries ago, but I guess he could still be upset, if you believe in reincarnation.

Now, there are some worrying questions here about freedom of speech in India, but they’ve been somewhat overshadowed by the discovery that the chap in question didn’t actually do it. The authorities went to Google (Orkut’s owner) for information on the perpetrator of this heinous crime. Google duly handed over the IP address, so they then went to the ISP concerned, who told them the user of that IP address, and he was promptly arrested and put in prison.

Unfortunately, the ISP, Airtel, seems to have slipped up and given the wrong information. After three weeks, this was discovered, and Mr. Kailash was released. The police are saying it’s not their fault, and that he should sue his ISP. Many of us have been tempted to sue our ISPs for a variety of reasons, but wrongful arrest isn’t usually one of them!

Anyway, there are some interesting lessons here for people like me who are dreadfully lax when it comes to campaigning about privacy issues. I’ve always said that I could never be a good conspiracy theorist because I don’t have sufficient faith in the competence of most authorities to construct a decent conspiracy.

But perhaps it’s the incompetence, not the conspiracies, that I should actually be worried about!

Atlanta burning

My friend Brian Lemaster, whom some of my readers will know, left the world of technology a little while back to join his family’s lumber business in Atlanta, which was founded in 1946.

Last week, this happened:

Norcross lumber

Fortunately nobody was hurt. At least, not physically.

But that must be an experience he and his family won’t forget very soon…

My thoughts are with you, Brian!

How to give an excellent lecture

(As demonstrated tonight by Dr Tom Smith of Davas Ltd)

Start with a good opening slide:

Basic explosive chemistry

This will help get the audience’s attention, if anyone turned up:

full theatre

Explain clearly the theory behind your subject:

shell design

and reinforce your points, where possible, with some practical demonstrations.

Of course, if you chose the wrong career, say, accountancy, rather than firework manufacture and display, you may be at a slight disadvantage with some of these.

Understanding the numbers

A nice story from the Register – well, rather a depressing one really – about Camelot, the UK’s lottery operator, having to withdraw a recent scratchcard competition:

According to the Manchester Evening News, to qualify for a prize, punters had to “scratch away a window to reveal a temperature lower than the figure displayed on each card”. Sadly, as the card had a decidedly wintery theme, this initially-shown figure was often below zero.

Among these was Levenshulme’s Tina Farrel, a 23-year-old who admitted “she had left school without a maths GCSE”. She explained: “On one of my cards it said I had to find temperatures lower than -8. The numbers I uncovered were -6 and -7 so I thought I had won, and so did the woman in the shop.”

“I phoned Camelot and they fobbed me off with some story that -6 is higher, not lower, than -8, but I’m not having it.”

They had to withdraw the competition because rather large numbers of people had the same complaint…

The King is Dead?

It had to happen eventually, but perhaps it really is beginning now… in Japan at least. PC sales are falling, according to this AP article.

I have always looked forward to living in a post-PC world.

The personal computer as we normally picture it has been such a successful model over the last quarter of a century that it has stifled quite a lot of innovation because many ideas, which might otherwise have exciting new tangible forms, are easier just to do on a PC. But as PCs become less of a focus, we should see new types of interaction becoming more common.

Mark Weiser’s famous article, “The Computer for the 21st Century“, talks about when core technologies become really powerful: when you don’t notice them any more.

The most frequently-cited example of this – highlighted by Don Norman – is the electric motor. There was a time when you could buy a ‘household electric motor’ and a range of accessories which would allow you to use it as a blender one minute, and a vacuum cleaner the next. But you know electric motors have become really significant as a technology when you start thinking of a washing machine as a washing machine, and a drill as a drill, rather than as incarnations of an electric motor.

Perhaps that’s what we’re starting to see in Japan.

Millions download music directly to their mobiles, and many more use their handsets for online shopping and to play games. Digital cameras connect directly to printers and high-definition TVs for viewing photos, bypassing PCs altogether. Movies now download straight to TVs.

More than 50 percent of Japanese send e-mail and browse the Internet from their mobile phones, according to a 2006 survey by the Ministry of Internal Affairs. The same survey found that 30 percent of people with e-mail on their phones used PC-based e-mail less, including 4 percent who said they had stopped sending e-mails from PCs completely.

Now, to be fair, it’s not clear that people are actually doing without traditional PCs, they just aren’t upgrading their old ones very fast.

But this is a start. One thing that characterises appliances like washing machines, at least for most of us, is that you replace them when you have to. You don’t buy a new one so you can boast to your friends that this years’ model has a higher-wattage motor.

This is not the end of personal computing. It is not even the beginning of the end. But it is, perhaps, the end of the beginning.

What fun!

Leopard continued

In a wild burst of enthusiasm, I updated our other two Macs to Leopard yesterday.

These were both upgrades rather than clean installs, and I did fall foul of another glitch which can affect upgrades. It’s easy to fix once you know what’s happening, but ironically it manifests itself as an unresponsive “blue screen”, which appears when the system first boots after the OS installation and so can be a little worrying!

The issue is a third-party subsystem called ‘Application Enhancer‘ (‘APE’) which you may never knowingly have installed but which is distributed as part of a few popular utilities and so may be on your system. It doesn’t work under Leopard, which is fine, but unfortunately, early versions of APE will cause the Leopard login window to crash. If you do an Upgrade installation of Leopard, which doesn’t remove such things from your system, you never get a chance to log in to your shiny new OS!

Some argue that this isn’t really Apple’s fault, because APE puts hooks into the OS in ways that weren’t really intended, and is installed, like the Abomination of Desolation, in a place where it ought not to be. On the other hand, APE’s creator, Unsanity, point out that you have to be using a pretty elderly version of their library for this to be an issue.

Fortunately, there are various easy ways to make sure this doesn’t happen to you:

  • Check, before you install, whether you have any of the following files on your machine and delete them if so:
    /System/Library/SystemConfiguration/ApplicationEnhancer.bundle
    

    (that’s the important one)

    /Library/Frameworks/ApplicationEnhancer.framework
    /Library/PreferencePanes/Application\ Enhancer.prefpane
    /Library/Preferences/com.unsanity.ape.plist
    
  • or, install the latest version of APE before beginning
  • or, install Leopard by doing an ‘archive and install’ rather than an ‘upgrade’
  • or, if you find you’re already in this situation, you can fix it by booting into single-user mode and running a couple of commands as described in Apple’s article on the problem.

So, perhaps because I’m a somewhat unusual user, two out of our three Macs hit issues on the Leopard install. This is bad. On the other hand, they were the most common issues others have faced too, and were quickly resolved by Googling.

I can’t comment on the long-term stability of Leopard yet, but I’m very pleased with how well everything seems to be working now it’s up and running. I was expecting a lot more pain, or at least inconvenience.

There was a nasty moment when I thought that one of my network printers wasn’t supported, but everything went much better after I went into the next room and discovered that it wasn’t actually turned on!

Leopard, Leopard, burning bright

This is my first post from my Macbook Pro running under Leopard. So far everything is going swimmingly and I’m enjoying it a lot. As others have said, most of the improvements are under the hood, but in general I like the new stuff that is visible, and everything feels just that bit snappier. How much this is due to Leopard, and how much to the removal of a few years’ miscellaneous junk from my hard disk is hard to say, but it’s very nice.

I did a clean ‘Erase and install’, having first made a couple of clones of my disk using SuperDuper. I then used the migration assistant to copy all my docs and settings back from the clone, but I didn’t copy all the applications; I wanted to thin those out. The ones I wanted I’ve either re-installed from their original media or copied over by hand.

A couple of tips:

  1. If you know that you want to do a clean install, then I suggest booting from your clone disk and using Disk Utility to format your main one before starting.

    Why? Well, during the install process each of your hard disks will be checked to see if they’re a suitable location for the installation, and then you’re able to choose between them. For some reason, certain disks can take a very long time to appear. There are various discussions about this on the Apple discussion forums, but the answer seems to be just to wait. In my case, I suspect because my hard disk was so full, it took over half an hour, with no progress indication, before the disk appeared and I could continue with the install. That was a few nights ago, and I didn’t have time to continue after that. It’s a big flaw, but it’s the only one I’ve seen in an otherwise painless upgrade process.

    This time, I had formatted the drive beforehand, and everything was very quick.

  2. A new but little-known feature in Disk Utility is the ability to resize Mac partitions non-destructively. Like me, you may want to try out the very sweet new Time Machine backup system, but it needs its own disk or partition for the backups. I had a big external drive with lots of space free and was able to split it into two partitions to make space for Time Machine. This should, of course, always be done with care, and generally after, rather than before, making backups!

All in all, so far, I’m very glad I upgraded. Lots of things that I thought might not work are working just fine, and some things very much better.

The Best Way to upgrade Mac OS X

John Gruber has exactly the right prescription:

  1. Do a complete backup clone to an external FireWire drive.
  2. Test that the backup is indeed bootable and up to date.
  3. Unplug the backup drive.
  4. Boot from the installer DVD and perform a default upgrade.

This is how I’ve done the last few upgrades, but when my copy of Leopard arrives next week I think I may do a clean install. I haven’t done one for many years, and there’s probably lots of accumulated sediment… I could do with a spring clean.

I’m only really doing this because I’d like to stop running my machine with its disk 98% full! I regularly use OmniDiskSweeper to find and remove major space-hogs – video podcasts that I watched long ago and forgot to delete, for example. And I long ago moved most of my photos and videos to external drives. But now I suspect it’s the thousands of smaller files – logs from utilities I tried under 10.3 and such – that make a significant contribution… We’ll see… 100GB ain’t what it used to be…

The Persistent Image

2007-10-27_15-40-14.jpg

Here’s a story about miracles. Lots of them. Technological ones.

BBC4 last week aired the first episode of a series called The Genius of Photography. It was excellent and I would have missed it completely, but just as it was beginning, John, knowing that I have an EyeTV setup, sent me a text asking if I could record it.

I was working on my laptop downstairs when my phone chirped the message’s incoming arrival. I glanced at the time and saw that the show was just beginning so, with a couple of keystrokes, made a VNC connection to the Mac Mini on the top floor – all wireless, of course – and saw that the opening credits were just beginning. I clicked record on EyeTV, then went back to work.

It occurred to me that it might be fun to watch it on my new iPod Touch, so later that night I clicked on EyeTV’s convenient ‘export for iPod’ button before going to bed.

2007-10-27_15-35-30.jpg

This afternoon, I slipped into my most comfortable pair of headphones and curled up on the sofa in front of the fire to watch the first episode, which was titled ‘Fixing the Shadows’, about the earliest days of photography.

2007-10-27_15-43-40.jpg

It was most engaging, beautifully produced, and the gorgeous iPod screen was a joy to watch.

2007-10-27_15-42-08.jpg

And as if this wasn’t compelling enough, it began to dawn on me just what I was doing…

Here I was, looking at a horse going around a track in Palo Alto. Except I wasn’t really, I was looking at some of Eadweard Muybridge’s famous 1878 photos of such a horse (taken, incidentally, to satisfy the curiosity of the horse’s owner – a chap named Stanford. His racecourse is used for something else now!)

Muybridge Stanford racehorse

Mind you, I was really being shown these photos by somebody pointing a TV camera at them somewhere. Of course, I wasn’t seeing what came out of the TV camera. Oh no. That had been recorded, and edited, and stored, and encoded, and transmitted, and received, and stored, and decoded, and re-encoded, and transmitted and stored again, and synced to my iPod, and decoded again, with the net result that I could see it glowing on a little LCD screen I had just taken out of my shirt pocket.

2007-10-27_15-46-14.jpg

Of course, that’s an abbreviated summary of what happened, and it’s just the start. Think about how many further processes the images went through so that you could see them on your screen now!

I boggled at all of this for a moment.

Then I tapped the screen and went back to learning just how hard it had been for Daguerre, Fox Talbot et al to capture any kind of images which would persist rather than fading after a few seconds. And how they had changed the world when they eventually did so.

Ancient history? No.

That was about one and a half lifetimes ago.
