Private IP Addresses Showing In Public Webserver Logging

Today I was spelunking through some logging on the Squarespace backend, and found something peculiar.

The IP address marked by the red frame is a so-called private IP address.

In the Internet addressing architecture, a private network is a network that uses private IP address space, following the standards set by RFC 1918 and RFC 4193. These addresses are commonly used for home, office, and enterprise local area networks (LANs), when globally routable addresses are not mandatory, or are not available for the intended network applications.

These shouldn't show up in the logging of a webserver which is connected to the Internet. Further investigation revealed several other IP addresses;

I opened a support ticket @Squarespace to check if these might be internal addresses. If so, they are using a lot of internal networks.

Reset 'Open With' Dialog in Finder

After the upgrade of several programs I found that these programs had multiple entries in the 'Open With' dialog in OS X Finder. The following command (executed in the Terminal app) rebuilds the LaunchService database, and removes the duplicate entries.

Note that the following command is 1 (one) line of code, that you need to copy & past in the terminal window.

/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user

As far as I can tell, it works on OS X Mountain Lion and every earlier version (at least till 10.6).

Nicotine Vaccine... WTF?!

While browsing the news sites, I stumbled upon this Nicotine Vaccine video on Reuters. Nicotine (smoking)... Vaccine? Since when is smoking caused by a virus?

A vaccine is a biological preparation that improves immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism, and is often made from weakened or killed forms of the microbe, its toxins or one of its surface proteins. The agent stimulates the body's immune system to recognize the agent as foreign, destroy it, and "remember" it, so that the immune system can more easily recognize and destroy any of these microorganisms that it later encounters.

What's next? A vaccine for Kleptomania? Bad driving? Being obnoxious? This is (in my opinion) nothing more than an effort of Big Pharma to have us take more and more drugs. They have to do something to keep their investors happy since more and more drug patents are expiring.

Best 'Unboxing Videos' Ever

It's the best, mainly because it's terrible. It's a montage of several unboxing videos of the Google Nexus phone/tablet thinghy. I guess I would have thrown the entire box + contents out of the window. Google can learn a lot from other companies like; Nikon, Canon, Leica, Apple... Hell, even the shrink wrap on Microsoft products are easier to remove. Unboxing is an integral part of the new gadget/thinghy experience nowadays.

Pearl Jam June 26th @ Ziggo Dome (NL)

Some photos and videos from the Pearl Jam concert @ the new music venture/hall Ziggo Dome in Amsterdam (NL). I hope you like them.

The new Ziggo Dome is a large version of the Heineken Music Hall; Especially built for live music performances. We probably had the worst seats in the house (top left corner), but even there the sound was excellent.
