Space shuttle transport!

mei 25, 2009

After the return of space shuttle Atlantis, it has to be transported back to Kennedy Space Center in Florida! This will be done with a Shuttle Carrier Aircraft or SCA, which are essentially two heavily modified Boeing 747 airliners – one being a 747-100 and the other is a shorter range 747-100SR. The Space Shuttle is attached to the top of the SCA using Mate-Demate Devices, which are large structures used to hoist the orbiter from the ground.

During early tests of using SCA as a transport vehicle for the Shuttle, the Shuttle was released from the SCA during a flight at over 30,000 feet and the Shuttle was able to glide down for a successful landing on its own without any engines powered.

The SCA has a maximum takeoff weight of 710,000 lbs, has a length of 231 feet and a wingspan of 195 feet.

In about a week the Shuttle will have returned to Florida where it will be prepared for its next mission, the STS-129. The STS-129 shuttle mission is scheduled for November of 2009 and will be used to deliver components including two spare gyroscopes, two nitrogen tank assemblies, two pump modules, an ammonia tank assembly and a spare latching end effector for the station’s robotic arm to the International Space Station.

The next Space Shuttle flight, mission STS-127, is scheduled currently for June 13th 2009 for a 7:17AM launch time – weather permitting. The mission will deliver Timothy L. Kopra to the station as a flight engineer and science officer and return Japanese astronaut Koichi Wakata to Earth. Hurley, Cassidy, Marshburn and Kopra will be making their first trips to space. The Endeavor Shuttle will also deliver the Kibo Japanese Experiment Module Exposed Facility and Experiment Logistics Module Exposed Section to the International Space Station.

The facility will provide a type of “front porch” for experiments in the exposed environment, and a robotic arm that will be attached to the Kibo Pressurized Module and used to position experiments outside the station. The mission will include five spacewalks.

explore new ways to extend & personalize your Firefox

mei 24, 2009

Mozilla is going to extend firefox with a new add-on feature. This feature makes it possible to install add-ons without have to restart your firefox browser.

Mozilla want with Jetpack to add a new Add-ons-Plattform and hope to increase the number of  the Add-ons-developers. The first version of  Jetpack (0.1) is capable of:

  • Initial Jetpack APIs with support for statusbars, tabs, content-scripts, animations, and more.
  • Support for external API libraries (e.g. Twitter)
  • jQuery support
  • Integrated development environment with Bespin, with immediate installs and a fast development cycle
  • Inline debugging with Firebug
  • This initial release of the Jetpack API does not include a fully formed security model. It is being released for testing, development, and feedback.

The Jetpack-Initial version is just for testing, developers and to gain feedback.  To make it easy to get some work done with Jetpack the developers have made a Tutorial and some Demos . Jetpack can be downloaded here.

Proxmox an update!

mei 23, 2009

Due to my interest in virtualisation technologies I like to try things. And as mentioned before I think proxmox will be my choice of virtualisation technology at home.

Why? because it is free, it works!!

 

Today I have converted my Free Citrix Xenserver to proxmox, this due to an error on the xenserver with a vm, and second because I needed a second KVM compatible machine.

I also did a migration from the master node to the newly node from a windows xp machine.  And it went smoothly. I am still very impressed by it. But I like it very much.

So you also want a cluster with proxmox? Here is how to do it:

On the machine which should be come the master node you type:

  • pveca -c

On the machine which should be come a node within the cluster you type:

  • pveca -a -h <ip address of the master node>    e.g.: 192.168.1.100

 

And your cluster is done… yes that simple, of course the nodes are going to synchronize with each other.

After this you can do a live migration or a migration to the other node. Good luck and keep me posted how it went.

Proxmox live migration tested! And it….

mei 20, 2009

An update:

I have installed Proxmox on two different type of machines, the configuration is:

  1. AMD Athlon(tm) 64 X2 Dual Core Processor 4200+ with 4GB of Ram
  2. (Intel Atom)  Genuine Intel(R) CPU  230   @ 1.60GHz  with 2GB of Ram
  3. network = 100Mbit

With this configuration I have migrated a debian OpenVz  virtual machine from the AMD to the Intel Atom machine. And I can report to you it really works nicely. Also migrating the virtual machine back from the Intel Atom to the AMD X2 with online migration is working very nicely.

I am very impressed and this offers possibilities. I go so far that it will become my virtual enviroment of choice, but this after a test with migrating a KVM virtual machine back and forward, this ofcourse can’t be done with my current configuration, so I have to do an installation of proxmox on another machine with virtualisation technology inside it and this supported in the BIOS!  I will post my results here.

eislon.

Xen 3.4 is released

mei 19, 2009

The Xen developers  have released version 3.4 of thier  virtualisation technology.

This version  3.4.0 of the paravirtualisation Xen contains the first version of the Xen Client Initiative (XCI) code. XCI should be a basic-client-hypervisor, which can be enhanced and extended by the Open-Source community. Xen hopes that this will bring the system to other hardwareplatforms.

New features of Xen 3.4 are:

  • stability is improved;
  • System errors should be given and being isolated, which should help Xen to just run on.;
  • Xen is made greener (powersaving).

Xen 3.4.0 can be downloaded as source code here.

Microsoft and Linux Foundation agree !

mei 19, 2009

Microsoft and the Linux Foundation agree on something. Neither wants to stand behind their products.

The two joined forces on a letter to the American Law Institute taking issue with its proposal, which is an implied warranty that software products ship with no material defects.  Microsoft and the Linux Foundation believe the proposal could do more harm than good.

Microsoft and the Linux Foundation aren’t the only ones against this, the University of Houston’s Raymond Nimmer also wrote a biting critique of the ALI proposal.

We will see what the future will bring us.

Proxmox Virtual Enviroment

mei 18, 2009

Proxmox Virtual Environment is an easy to use Open Source virtualization platform for running Virtual Appliances and Virtual Machines.

It is able to use the OpenVZ and KVM virtualisation methodes, for the KVM you will need a processor which supports cpu virtualisation so it should have AMD-V or INTEL-VT technology on board. Many CPU’s have this, but mostly they are disabled, so it should be enabled into your BIOS , if this is possible!

I have had a quick look at Proxmox, cause the idea of a Open Source virtualisation enviroment would be to good to be true, yes there is a company behind it, and yes ofcourse they like to sell thier applications, but the Proxmox Virtual Enviroment is licensed under the GPL 2 license.

A quick look deserves a quick review:

  • Installation piece of cake (watch out your harddrive will be erased so make a backup)
  • amount of interactive action are little.
  • management is through a ajax based website (you need java to be installed for the VNC console).
  • First impression is very good.

I give you here the vision of proxmox:

“Setup a complete virtual server infrastructure within 1 hour.” Starting from bare metal, it is possible to create a full featured enterprise infrastructure including an email proxy, web proxy, groupware, wiki, web cms, crm, trouble ticket system, intranet … – including backup/restore and live migration.

Nowadays people are faced with more and more complex server software and installation methods. But Proxmox VE is different.

Proxmox VE is simple to use:

  • Pre-built Virtual Appliances
  • Install and manage with a view clicks
  • Selection of products for the use in the enterprise

Proxmox VE is licensed under GPLv2 (Open source). Open source and commercial Virtual Appliances are supported.

Windows7 problems with XP compatibility mode

mei 16, 2009

There seems to be a problem with Microsoft’s Windows 7  XP compatibility mode.

Due to the fact that this is build on the virtualisation technology built-in with the processors. It points to the AMD-V or INTEL-VT technology. These hardware virtualisation is not builtin into all pc’s , or is builtin but can’t be enabled cause the option is not available in the PC’s BIOS (which is a nasty thing to forget 😉  So if your pc can’t use or have these technologies you won’t be able to use the XP Compatibility mode. However you could always install VMware Workstation perhaps even player to have your old Windows XP installed as a VM and run you “old”  programs on it!
