iMac G5 Death Throes

The iMac G5 named iFive, which I boot without a keyboard, is in its death throes: it crashed again while booting up. Power supply issue? This time, I could save the report to Apple. Reporting didn't work until I plugged in a USB mouse.

So, here it is:

Leopard's built-in VNC server doesn't quite work

It would be great -- if it worked. Paul Holbrook notes in his blog:

Mac OS 10.5 has a VNC server built in to allow remote access back to your Mac. Many sites have claimed that standard VNC clients will work with Mac OS VNC.

Mr. Holbrook reports some success with Windows on the LAN, but nothing from a remote client. I haven't had any luck connecting over the LAN using the Linux command line client, xvncviewer. I get the following error:

main: End of stream

It's not the firewall, since the superb Vine Server 3.0 for Mac OS X 10.4 & 10.5 worked like a champ: I installed it on my Leopard machine, and then connected immediately with xvncviewer over the LAN.

I'll let you know if I get the remote connection going.

MAMP Virtual Domains

Set up virtual domains for MAMP with this great hack from springworks.
Be sure to quit MAMP first.

From the tip on the Joynet board:

1. With a text editor that can open hidden files (eg TextWrangler (free) or TextMate), open /private/etc/hosts
2. Find the line which reads

Code:

127.0.0.1    localhost

3. add the name of your chosen virtualhosts at the end of this line, separating each of them with a space, like this:

Code:

127.0.0.1    localhost mytestdomain1.dev mytestdomain2.dev

4. Save the file. You will need to provide an Administrator password to do this.

5. Create a folder for each of your test domains in the Sites folder in your home folder, eg:

/Users/myusername/Sites/mytestdomain1.dev

/Users/myusername/Sites/mytestdomain2.dev

6. Now open the MAMP httpd.conf, which you can find in /Applications/MAMP/conf/apache/httpd.conf

7. At the end of this file, insert the following:

Code:

NameVirtualHost *:80
<VirtualHost *:80>
ServerName localhost
DocumentRoot "/Users/myusername/Sites"
</VirtualHost>
<VirtualHost *:80>ServerName mytestdomain1.dev
DocumentRoot "/Users/myusername/Sites/mytestdomain1.dev"
</VirtualHost>
<VirtualHost *:80>
ServerName mytestdomain2.dev
DocumentRoot "/Users/myusername/Sites/mytestdomain2.dev"
</VirtualHost>

8. In the MAMP preferences, choose the Ports section and click on the "Use default Apache and MySQL ports". Now stop the MAMP servers and restart them again.

You should now be able to reach all of your test domains at the same time, using just the domain name as the address, none of this "localhost:8888/mytestdomain1/" stuff.

Tidy Service

Tidy Service is a simple OS X Service that cleans up markup using the powerful HTML Tidy library originally created by Dave Raggett.

[From Tidy Service]

Works great with TextWrangler.
