Perseid Meteor Shower

In the second weekend of August 2012 we experienced another Perseid meteor shower in the Netherlands. During this event I tried to photograph the meteor trails... unsuccessfully, until I re-checked my photographs this weekend.

I will prepare myself a little better next time.

Leica à la Carte

Leica M7 à la CarteThis post is for everyone who wishes me the best. In this case, the best à la carte (film-based) Leica M camera. Our German friends @ Leica created a website called 'Leica à la Carte' where you can order a fully customizable Leica M7 or MP.

They have a nice wizard where you can specify every option for the M camera, but in stead of hitting a submit button at the end, you need to download the PDF (containing the customization), print it, and (snail)mail it to a selected Leica reseller, who will order it with Leica.... A real old-skool process for an excellent old-skool film camera.

So for those who want to order me a customized Leica M7; Just download this PDF, where I did all the customization work already. Just contact me for the shipping information, and I'll send you an exclusive un-boxing video of the Leica camera, and a handwritten thank-you-note once it arrives.

Ziggo Internet, Juniper Firewalls and DHCP

At the house I have currently two ISP delivering broadband. Well, broadband isn't the correct word, since the the one of them is only a mere 256kbps (I think). The other is a 'whopping' 20Mbps.
The 20Mb connection is provided by XS4ALL, and the 256kbps is for free (if you have a phone subscription with Ziggo). The 256kbp is the minimum they provide to transport the phone calls, but if you're a masochist you can also browse the internet over that connection.

So, two ISP @ home. Combine that with a Juniper SRX firewall, and a dual ISP setup is born. The theory of that setup is that I connect both ISP's to the firewall, and use the 20Mb line as a default internet connection, but when that one dies, I automatically get switched to the backup line (256kbps).

A Weekend During the Summer of 2012

This weekend we escaped the rat-race and took some 'off-time' at/near the beach in Zandvoort (NH). The town is situated on the North sea coast, and during the (summer) holiday season packed with tourists....

Summer of 2012 Well, not this weekend (and I guess not even this summer season), because summer is slow at this year in Holland.

Unable To Turn On Wireless In OS X Mountain Lion

Last night I was minding my own business on the couch, when the wireless connection on my MacBook (UniBody)  decided to call it a day. According to the symptoms (no bars visible in the WiFi icon in the menu bar, no visible wireless networks in the vicinity), the WiFi adapter was turned off. Turning the WiFi back on was not possible though.

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).
