Fixing misalignment without moving data

Fixing misaligned partitions

It’s quite an old topic, but I recently found a great tool which allows you to re-align partitions without the need to manually move data from the misaligned disk to a new aligned disk.

First of all I must add that all the credits go to Nicholas Weaver, since he wrote the original blog and the actual tool!

We’ve all been there: you have a certain Windows virtual machine with several disks of the same size and you don’t know which Windows-disk is in fact which storage LUN.

The VMware settings for this VM might look like this:

Will the new WiFi super antenna change the world?

A Dutch invention will change the WiFi world drastically

At least, that’s what Roel Pieper and Marcel Boekhoorn are convinced of. The revolutionary super antenna should cause all problems concerning the reach of indoor WiFi signals to disappear. Furthermore this new product is supposed to make an end to wireless antennas interfering with each other’s frequencies and smartphones will get a better reception because of this new invention. The new antenna should be better and more advanced than anything else currently known to mankind. On average a smart phone needs about seven different antennas, but with the new invention only a single one is needed. And on top of this using the new antenna more data can be sent and received compared to the existing ones.

Mathematical super-formula

Boekhoorn and Pieper worked together in a company called “Antenna Company”, which will produce these next-gen antennas. The technique is based on a mathematical super-formula made up by Professor Gielis and it’s called the “Super-formula“.

Roel Pieper is appointed as the CEO of the “Antenna Company” and they’re already talking to various multinationals about applying the antenna in cell phones, cars and routers according to the Dutch newspaper “de Telegraaf”. Other applications could be airplanes, medical equipment, weaponry and radar systems, but other equipment that needs to communicate with other equipment, such as central heating thermostats.

World hit

Antenna Company “promises to be my most successful company ever”, according to Boekhoorn in an exclusive interview by Quote. The 3D-optimized antenna can potentially make billions of Euros. “This super antenna will be a hit.” HTC, LG and Samsung are potential customers according to the billionaire. The Antenna Company is already talking to several of these multinationals. Even Cisco is supposedly interested.

High Tech Campus

Production of these super-antennas will start in March. The Antenna Company will settle at the High Tech Campus in Eindhoven in the Netherlands. The Head Quarters is formally located on Curacao. Exactly how much Boekhoorn has invested in the project, he’s unwilling to say..

Which Cisco NX-OS should I use?

This time a really short reminder-like post. Somehow I often end up trying to locate certain release notes of various equipment, but Cisco organized theirs for the SAN switches in an orderly manner: Release Notes

Every NX-OS version is listed here and in each all supported equipment is named. I found this to be very helpful.
