Another holiday snap

…from my recent trip to the Pyrenees.

Val d'Azun

f1.5

Regular readers will know that I was hoping for some update to Apple’s Aperture software to be announced today. And sure enough, Aperture 1.5 will be a free upgrade later this week, with lots of nice new features.

As always with Aperture, there are video tours and tutorials including one which shows you what’s new in this version. (Here’s a direct link to that movie.)

Skype video for Mac

Skype betaThere’s now a 2.0 beta version of Skype for the Mac, which includes video chat.

Almost everybody I know is on AIM, so for regular IM chatting I use iChat, with the occasional audio or video link to other Mac users. But Skype has always been better at getting through firewalls than iChat, and this could make it a better video solution, especially if the quality is as good as iChat.

Slipping through security

Manka Johnson has a few interesting thoughts on airport security. Like the fact that, while you aren’t allowed to take water on board, you are allowed to take KY jelly. Mmm.

sshput

Warning – geeky post

I often configure SSH so that I can log in from one machine to another without typing a password. Those who have done it, though, will know that this takes a few steps and it’s easy to make mistakes.

I wrote a little script to help, and found I used it rather often. So with due humility I offer sshput to the world in the hope that others might also find it useful.

Playing with the big boys

On Thursday, the Bush administration committed $3bn to projects tackling climate change issues. The following day, Richard Branson did the same.

Neither of these gestures is exactly philanthropic in nature; both Sir Richard and the United States of America need to find alternative fuels, and realise that heavy investing in this area probably makes long-term economic sense. But, as someone who can’t even afford a Prius, I can’t help thinking that it must be nice to wake up and think, “America’s doing this. Maybe I’ll do the same thing.”

Car Karma

I like Claes-Frederik’s ideas on a way to reduce road-rage and make traffic more friendly.

Run!

Hamachi

Hamachi looks interesting. It allows you to create a VPN – a private network – between arbitrary groups of friends or co-workers, and join or leave it simply by clicking a button.

Normally, I detest VPNs. They’re a good idea in theory – make you look as if you’re on your office network when you’re somewhere else – but my experiences of them at three different organisations has not been good. Fortunately I’m geeky enough to find alternative solutions using things like SSH, VNC, SFTP and WebDAV, which generally have performed much better. These days, though, if you have many mobile workers, it can be better to put your company services out there on the internet (with appropriate security measures, of course) where they can be accessed from your own network and from elsewhere.

However, more peer-to-peerish solutions like Hamachi could be very useful if, say, you want to back up your mother’s PC or print on your brother’s printer. As well as Windows support, there are console versions for Mac and Linux, and a new version with a GUI for Mac OS X.

Disclaimer – I haven’t tried any of these. Just an interested observer.

Ndiyo, and Yours Truly, are mentioned in this week’s Economist.

Better Google Maps labels

I don’t know about you, but I’m always sending Google Maps locations to people who are coming to visit. I usually type in my postal code and send a link to the resulting map, with a bit of explanation:

“Here we are. Well, actually, we’re not quite here, we’re at the end of the street and on the other side of the road, but this should give you an idea of how to find us.”

I wanted to do something better than this, and while I knew all kinds of sophisticated things were possible with a bit of Javascript and the Google API, I just don’t have the time to play with this at present, much to my chagrin. So here’s my quick guide on how to create a useful, short URL that will really tell people where you live, and will take them to something like this:

Quentin and Rose

Here’s how I got this:

  1. If searching for placenames or postal/zip codes doesn’t give you a good enough location, you need to use latitude and longitude. If you have a GPS handy, you can just step outside your front door and take a reading.
  2. If not, then you need to find your location some other way. In the UK, I suggest going to Streetmap and getting an approximate fix using your postcode. You can click on the map to move the pointer to the right place. Then, at the bottom of the page, find the little link saying ‘Click here to convert/measure coordinates’. This will give you the location in a variety of forms. Make a note of the decimal version of your Lat and Long. For me these were 52.194421 and 0.107796.
  3. If you’re in another part of the world, or Streetmap doesn’t work for you, you can find your Lat & Long on Multimap.com at the bottom of the page. Click to zoom in and it will show the position of the last point you clicked.
  4. OK, now you’re armed with your approximate location, head back to Google Maps and in the search box type the lat and long separated by a comma or a space. This should take you to something that looks pretty familiar.
    Approximate location
  5. I wanted to get a more accurate fix, so I switched into Satellite view and tweaked the numbers until the arrow pointed pretty much at my front door. (We’re blessed with nice high resolution images here in Cambridge.) Remember, increasing the frst number will move the pointer up, and increasing the second will move it to the right. Keep your changes small – you probably want to play with changes around the 4th decimal place or so.
  6. Now, add the label you want, by putting it in parentheses after the coordinates:
    52.194405, 0.1074 (Quentin and Rose)
  7. Choose the view you prefer. For this purpose I like the Hybrid one, which overlays the road names on the satellite view.
  8. When you’ve got it how you want it, use the ‘Link to this page’ link at the top right of the map to get a URL that represents the current state. On my Mac, I just right-clicked it to copy the link.
  9. For a final neat touch, go to TinyURL and paste this URL, which may be rather unwieldy, into the box on the TinyURL front page. That will give you a nice short address like this: http://tinyurl.com/ps2xw, which does the same thing. Make a note of it, or store it as a manually-created bookmark.

After this you have a handy URL short enough to memorize, that you can email to friends, dictate over the phone or even send in a text message, and that will bring them right to your front door!

Widescreen

Most ordinary users don’t need their digital camera to have more than about 3 or 4 megapixels. Even at that point, the quality of the optics is more important than the number of pixels.

But those who disagree with me, or who aren’t ordinary users, might be interested in the upcoming offering from Seitz:

Seitz camera

At 160 Mpixels, taking nearly a GB per image, it dispenses with flash cards and uses a Mac Mini in a satchel instead.

But any temptation I might have had to splash out 29,000 euros on one of these vanished when I realised that it wouldn’t quite fit in my pocket.
