Update: Powerline adapters

Now that I finally was fed up and has won inertia I bought new Powerline adapter.

Previously I had worked the 85Mbit version to say the least bad, now, after upgrading to the versions of 200Mbit Netgear ( dLAN 200 AVeasy ) I'm pleasantly surprised. Meanwhile, considerable 40Mbit actually go through the power lines that is a significant progress to advance.

VMWare Links

I'm just about http://www.vm-help.com/ stumbled, here there is something useful to VMware's ESX (i).

In addition, under http://cars.lostroncos.org/2008/03/07/updated-esx-3i-scripts-for-nagios/ read some of the various Nagios plugins found via VMWare perlapi states and thus a possible alternative to check_esx are by Steve Shipway.

Network vs. cable. Powerline adapters

After I had already noticed the more I want to network performance can remain strong at home, I have been last week (the suffering was finally high enough) for troubleshooting. The tool IPerf has uncovered the problems.

For the connection between the hall from the ground floor and the DSL connection in the basement I use powerline adapter from Zyxel (PL-100) and to my horror I realized that the promised 85Mbps which will supposedly go on the grid, only 2 words, two Mbit remain. Why is unfortunately not possible to say exactly because the Poser line adapter, of course, are unmanaged components.

The whole thing is an absolute disaster ... and I've always been wondering why streaming video works, etc. totally or not at all ponderous. The troubleshooting will be as disastrous's not what I expected.

Now normal network cable to be laid ... I should have done from the beginning.

Migration Wizard

Yesterday I got my new Mac because I wanted the course as quickly as possible into operation I have the OSX's "Migration Assistant" is used.

The wizard takes over completely automates all user-specific data and installed programs from one Mac to another. It works perfectly over the network and took about 3 to 4 hours for 30GB data scarce.

As a previous Linux and Windows users this is an entirely new behavior, after a hardware update to install any programs newly received, the entire browser history remains, mail clients do not set up new, etc. ....

Another point that speaks for the Mac.

Media Center

I'm just looking for a sitting-room media center solution. Here I am on Plex pushed replacement (formerly OSXBMC) based on a MacOS X X-Box Media Center, which all looks very promising especially as the developer of Plex cooperation with CenterStage, a Mac-based HTPC system have further closed.

The optimal solution would be the whole or combine it with a DVB-S receiver (EyeTV 310), as would my wireless keyboard, the diNovo Mini by Logitech hover. So it is possible to easily check e-mails just before the TV or surf the Internet.

money for expensive hardware cheap?

It was once about a year ago .... could begin the story, since acquired a Mac newbie his first Macbook Pro.
Since then, he is ambivalent between the user and the ergonomics of the software, unfortunately, terribly poor quality of the hardware.
Since buying the Macbook in May 2006, the known error of the Apple device "fiepens" in the CPU idle, shortly afterwards broke the coating of the inner band and was replaced on warranty. The settlement of warranty exchange was afloat in about 5! Weeks worked.
Recently, during hot weather is one of the two fans among the speakers, unfortunately, clearly audible through a loud crack.

If the hardware is probably about 10-15% higher than the price of a similar device from other major manufacturers do not pass something like that in my opinion.
The whole just does not fit with Apple and to gehörigem image.

All in all a very poor performance
