Edinburgh Leopard Tech Talk

Today I went along to the Leopard Tech Talk in Edinburgh at the posh Caledonian Hilton Hotel.

It was a very interesting event, and might just convince me to start programming in Cocoa and Objective-C 2.0. Objective-C 2.0 is far more like Java when it comes to memory management. This is where I tend to struggle in C. The event was under Apple Non-Disclosure Agreement (NDA), so I can’t publicly discuss anything that isn’t publicly available.
In the Cambridge Bar afterwards, one of the things that I tried to fix with the help of and Apple Tech guy was the Finder restarting when trying to change file permissions. This is mentioned in Apple support article 307128. However the instructions there don’t quite work. After some tries in the pub I was still getting the crash. Once I got home I had some tried the article again, and the second sudo dscl command seemed to wipe out the group record. In the end I did manage to get the problem fix, and I no longer get the crash.
I also got to play with an iPhone, and the reception on the O2 network is crap. The iPhone was only just, maybe thinking about getting a signal. On the other hand my Sony Ericsson k750i on the Vodafone network could get a full signal. Since I upgraded to Leopard I haven’t had my phone working as a bluetooth modem. With the help of the tutorial that I used the last time, and the GPRS network data table, I managed to get it working again.
The tutorial is now out of date of Leopard. On Leopard it is now a lot easier to setup. Once you have paired your phone, head into network preferences, and click Bluetooth in the left column. Then use the “User name” from the afore mentioned data table for the “Account Name” in Network preferences. The “Password” field uses the same name in both the data table and Network preferences. Next you need to click “Advanced…”. Select the appropriate vendor and model for your phone, and enter the appropriate APN from the data table. Hit “OK”, then “Apply” and you should be ready to connect.
At least now, the next time I go out with my laptop, and don’t want to pay for expensive wifi, I can use a little bit of data on my pay as you go phone.

  1. I’ve got the same problem here, with the crashes when I change file permissions. But no matter how many times I type in the two commands, it doesn’t seem to work. Could you help out?
