The notations for member activity are a quick visual measure of how engaged your subscribers are. You can segment on your member rating to send to your most engaged, or your least engaged if you want to bring them back in, etc

1 Star - negative rating, this person has unsubscribe and resubscribed, or soft bounced in the past

2 Star - no activity, never opened or clicked, most likely a new member, neutral rating

3 Star - this recipient has started opening or clicking your campaigns, limited activity

Encountered this error when I tried to upload a large file. nginx default is too small. To upload bigger file, add this line in /etc/nginx/nginx.conf, somewhere inside the http section:

http {
    ....
    client_max_body_size 20M;
    ....
}

Save, and then restart your nginx instance.

Self notes since I kept on jailbreaking my iPhone and reflashing my HTC Desire, and always forgot these settings:

• APN: celcom3g
• MMSC: http://mms.celcom.net.my
• MMS Proxy: 10.128.1.242
• MMS Port: 8080

Easy. Just follow these steps:

1. Obviously you need another Mac to which you want to backup to, with the disk formatted as Mac OS Extended Journaled.
2. Open Terminal from Mac you want to backup from. Issue command

 sudo defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1

3. Open System Preferences → Time Machine. Click Change Disk. Your network disk should appear now.
4. Select it, and you are good to go.

List of reliable RBL that we use internally and recommend to our customers.

My Mac have 4-core 3.0 GHz CPU with 4 GB RAM, yet this past week or so it seems to slow down to a crawl. Switching applications become sluggish, Dashboard taking its own sweet time to appear, and the CPU meter is constantly showing 100% usage in two of the core.

Tested under: CentOS 5.2, Ubuntu Intrepid Ibex (8.10), Ubuntu Hardy Heron (8.04), both 32-bit and 64-bit flavors. 

Tested working with the following clients: Windows XP, Windows Vista, iPhone, Mac OS X Leopard.

I'm running Ubuntu 7.10 using custom 2.6.23.11 kernel. Somehow, starting from kernel 2.6.23, VMware was unable to properly use my Windows Mobile PDA (Atom O2 Life). Every time I plugged in the Atom, VMware will spurt out "VMware Workstation was unable to claim the device" message. The issue was actually with VMware, and not the kernel. Follow the steps outlined below to work around this bug in VMware.
