It’s almost here!

One of the three authors has retired.

One has left the company.

One has a new assignment within the same company.

Three years after the “Dallas treaty“, when most of us have stopped believing that this will ever happen, we’re now finally in AUTH48: Combined User and Infrastructure ENUM in the Tree

[UPDATE, 2009/05/05]

It’s done. RFC5527 is now reality.

The starting point this time was a series of switches.

Stupidity at Evanzo

Dear Evanzo,

the contact emails in the whois records for the domains you manage are there for a purpose: If there are troubles with these domains, the responsible people can be contacted in order to get the problems fixed.

And there is a good reason these whois data is not just a blob of Ascii, but structured data: Scripts can parse the records and e.g. automatically send email to the right address.

Getting back autoreplies stating basically “please use this web-form” is not going to cut it. We will not special-case our scripts to fill out web-forms just to accommodate your setup.

You, and your customers will simply not get our Mails regarding defaced Websites hosted by your service.

Your decision, your loss.

I tried a different starting point with this one: a series of switches branching off a central piece of track. The result was a very tight, squiggly set of tracks.

Once again, the starting point was a simple oval.



Today I gave a talk at the ISPA office concerning DNSSEC. See here for the official announcement.

Attendance was good, we had interesting questions and a lively discussion.

Nokia 6120 Classic and A1 Broadband

When I got my company cell-phone two years ago, I opted for a Nokia 6120. The reasoning was simple: Nokia was supposed to have a decent user-interface, the phone could act as a 3G modem for my laptop and run various simple applications like Avantgo.

Well, …

The razor business model within IT

The razor business is said to have premiered the following business model: Sell the razor really cheap, but charge a lot for the blades.

Seeing the same in IT isn’t unusual, the prime examples are Inkjet printers where the printer is ridiculously cheap, but a new ink cartridge costs almost the same as the printer.

Cisco memory is another example.

I just noticed the same with HP’s new entry-level 1U server, the HP 120G5. We bought one for evaluation purposes for slightly above 500 €. Seems like a decent hardware: 1GB RAM, a Xeon processor and a single SATA harddisk. No frills, no chrome spoilers, just a straight forward server.

But: no on-board remote management. That would be extra. You need to buy the HP DL120 G5 Lights-Out 100c kit. We just plugged one of these into a DL 180, where we really need it. It’s a very tiny card. Just a PCI-E slot, a RJ45 jack and a single chip:

LO 100c

The price: ~ 200 €.
