Apple.com’s menu is slick.

Looking at it closer, I realized that the whole menu is one image with all four states on different y positions.

I decided to copy that, to learn how it works. Check out my results.
My menu-state-single-file looks stylesheet

I threw in some javascript to make the divs show and disappear as well

Have you tried using suckerfish menus and the scriptaculous slider. If you do, you might noticed that the menu doesn’t disappear after you mouseout in IE6/7 ?

Do you run an app server locally and test against it, using localhost?

Do you also run vmware fusion/parallels to test the same app in IE6/IE7 and other browsers you don’t care to run on a daily basis?

Do you wish you could type in localhost:3000 inside the vmware/parallel’s guest OS and it would just work. Instead you have to find the IP address of your host OS and possibly change some properties files as well?

I have that problem, my app has to redirect to another app and then come back to me, and those settings are kept in a properties file. So to test in vmware, i have to change properties files, lame. I’d like to be able to browse to localhost:3000 in IE6/7 in the guest OS

You can:

• find your host OS’s ip address. On a mac (running wireless), it’ll something like

  ifconfig -a 
  
  lo0: flags=8049 mtu 16384
  	inet6 fe80::1%lo0 prefixlen 64 scopeid 0×1 
  	inet 127.0.0.1 netmask 0xff000000 
  …..
  en0: flags=8863 mtu 1500
  ….
  en1: flags=8863 mtu 1500
  	inet6 fe80::21e:c2ff:fec4:1946%en1 prefixlen 64 scopeid 0×6 
  	inet 10.0.1.200 netmask 0xffffff00 broadcast 10.0.1.255
  
  

  In my case 10.0.1.200
• Download apache’s soap tunnel . This is an older one, but its better because the command line version doesn’t echo to system out.
• Copy the tunnel.jar to the vmware guest OS
• On the guest OS, open up a command/terminal window and run

  java -cp tunnel.jar TcpTunnel 3000 10.0.1.200 3000
  

  Change 10.0.1.200 to whatever your IP address is
• In your vmware guest OS, browse localhost:3000

Note: your host IP address might change if you restart it or have DHCP’d IP addresses. If that happens you have to start the tunnel again with updated IP.

We’ve been using the acts_as_rateable plugin at a client project. On a page, we needed to show items that weren’t rated or created by the logged in user.

Here’s some test tables, “videos” and “video_ratings”. Note: I’m using natural keys to make it simpler to read.

Videos
+------+------------------+
| id   | uploaded_by_user |
+------+------------------+
|    1 | tom              |
|    2 | mark             |
|    3 | tom              |
|    4 | mark             |
|    5 | tom              |
|    6 | john             |
+------+------------------+

Video_ratings:
+----------+--------+---------------+
| video_id | rating | rated_by_user |
+----------+--------+---------------+
|        1 |      5 | tom           |
|        1 |      4 | mark          |
|        5 |      2 | mark          |
+----------+--------+---------------+

The simplest query we could come up with was:

select id from videos
where not exists
  (select video_id as id from video_ratings
   where videos.id=video_ratings.video_id
   and video_ratings.rated_by_user='mark'
  )
and uploaded_by_user != 'mark'

This yields videos 3 and 6 (because 1, 5 already rated and 2, 4 uploaded by mark)
Can you think of any better/smarter query?

I read about XSLT in a book, a long time ago. Does anyone use it still?

Apparently, Blizzard does on the Warcraft armory site. and it’s a pretty spiffy one too.

Check out my character. Do view source and you’ll see what I mean.

These control interfaces are awesome.

I putted an order in for a sixty four.

Long time ago, I used matlab in school, to calculate heat distribution in cubes, I wish I could’ve done this kind of animation instead.
