As spectacular as they claim New Zealand is in the tourist ads on tv, it is. And then some. One thing I don’t understand is why so many kiwis are in Australia. But then maybe I should come back in winter to get my head around that

If you’re using Entourage this is how you move your appointments to Exchange from local folders:
1. Fire up Entourage
2. Click on Calendar in the toolbar
3. Click on “All events” under Calendar Views
4. Click on an event, and then click the edit menu, then “select all”:
4. Then right-click on a highlighted appointment and on the popup menu choose “move to” and then choose your Exchange Calendar:
NOTE this may look like it’s frozen as it moves the meetings across. Leave it to run for as long as it takes.

We’re rolling out new Macs at work in my team, and so I’m revisiting my must-have-done-before-I-start list. This is a list of things I’ve picked up from a lot of helpful and friendly mac users along the way:
Setup:



Free:
Commercial
Things I haven’t bought yet but want in future:
My notes from the presentation:
Sprites are cool, they were cool before and they’re still cool. Pillage ideas from late 80’s sci fi. Oh look, a bird. Forty two. Oh and don’t diss 8 bit. It’s also way cool.
That was the Pulp Fiction of Tech sessions. And I loved every minute of it
Speed Matters – by @markstanto
Things to come back to and probably search for later
Some of the concepts to be aware of:
Latency – overhead costs in round trip to server, besides actual data change
Profiling page loads with firebug
Interesting change – css stays up top, js goes as far down the page as possible.
Cache Controls
- ETags (Entity tags)
- Apache / IIS support. (server config)
Server will say “not modified, us cached”
Only good for single-server
Expires tag: specific date (or timespan?)
Apache config:
Big No’s
pragma:”no-cache”
cache-control: set to zero
Minify JS
- need to test all.
CompressorRater – tells you the savings using different algorithms
- use to choose best tool
GZip – only text files, not images
Split Components across Domains
- IE only 2 components at a time
- More than 3 aliases, DNS overhead counters benefit (we have much more than this)
Sprites
- composite images, use css to position
Restructure Content
- Delay loading of less imprtant stuff to later
Eg: Logo in css, images inline. logo shows after images.
Javascript rotator to lazy-load images (we should do this)
