I have another 22″ Acer and an HDMI slot for it,
but I’m all out of desk space.

This Google R&D guy gives a good rundown.

Long story short… The first IFrame src url will not be included in the browser history for static IFrames. However, all subsequent page urls within the IFrame will.

Unless… You do something tricky like insert the IFrame using JS or manipulate the src attribute in which case the behavior differs by browser and version.

I have or used to have:

• 
  TRAVS – An Asus Eee 1002HA netbook named after Boots of Travel
• 
  MJOLLNIR – A new Core i7 desktop named after Thor’s hammer, Mjollnir
• 
  DEFIANCE – A used 1U dual 3.06Ghz HP Proliant DL360 G3 webserver with 2Gb RAM running Centos 5.5 in a rack at HE in Fremont named after Hood of Defiance
• 
  MANTLE – A new Ubuntu VMWare guest instance running on Mjollnir with shared folders named after Mantle of Intelligence
• 
  IRONWOOD – A deceased Ubuntu VirtualBox VM instance named after Ironwood Branch
• 
  SANGE – A deceased desktop named after Sange (Sange and Yasha)
• 
  YASHA – A deceased desktop named after Yasha (Sange and Yasha)
• 
  RADIANCE – A previous company-owned laptop named after Radiance

But a little poking around yielded a better solution.

Turns out there’s a standard set of MySQL functions for translating an IP address to and from an integer.

ALTER TABLE `sessions` ADD `client_ip` INT NOT NULL AFTER `created_at`;
 
mysql> SELECT INET_ATON('192.168.10.50') AS ipn;
+------------+
| ipn        |
+------------+
| 3232238130 |
+------------+
 
mysql> SELECT INET_NTOA(3232238130) AS ipa;
+--------------+
| ipa          |
+--------------+
| 192.168.10.50 |
+--------------+

Here’s the algo in case you’re curious:

(192 * 2^24) + (168 * 2^16) + (10 * 2^8) + 50 = 3232238130

Shame on you, Microsoft. You should know better.
