new toy: Canon EOS 450D
Finally a DSLR landed at our premises: the Canon EOS 450D is as of now in our toy park – perfectly timed for the holidays and christmas.

Precisely 30 minutes before the weekend started for the support staff at the server hosting company this server is hosted .. well… it crashed.
So I waited till this morning and after merely seconds and new SATA cables the machine was up and running as if nothing ever happened.
DAMN CABLES!
So – everything should be fine now. Enjoy your stay.
In my case it’s just partly do-it-yourself: Michael and Peter did the cable soldering and I wrote the software that controls the serial interface to the PMR sender/receiver.
My gateway is on PMR channel 5 with no CTCSS configured in the Campus area of the TU-Ilmenau. A gateway is only just a PMR radio connected to a PC which is logged into a Teamspeak server which is connected to several other gateways (citizen radio / PMR / …)
So if you talk within the range of my gateway you’ll be heard in more than 24 areas across germany over PMR and citizen radio.
One toolset which was particularly useful is the VU-Meter tools. You can use them to monitor your input/output ports and tune them for perfect modulation. You can get them here and they look like this:
Since the cable soldering was one piece of craftsmanship a picture of the radio and the cable:

If you want to connect from outside the range of the PMR you should go to the homepage of Freies Funknetz and get all the necessary information there.

I virtualization heaven! I am currently using VMWare Server on most of the machines I am doing virtualization on – but the fact that the Microsoft Hypervisor “Hyper-V” is available for free now is really cool:
“Microsoft Hyper-V Server 2008, a bare metal hypervisor-based server virtualization product, is now available as a no-cost Web download at http://www.microsoft.com/Hyper-VServer. Microsoft Hyper-V Server 2008 provides a simplified, reliable and optimized virtualization solution for customers to consolidate Windows or Linux workloads onto a single physical server or to run client operating systems and applications in server-based virtual machines in the data center. Microsoft Hyper-V Server 2008 allows customers to leverage their existing provisioning, updating, management and support tools, processes and skills.”

Today I received a mysterious box with a SONY HDR-SR12E camera in it. I was expecting a camera but not one in HD (1080i) and with a humongous hard disk (120GB).
Since it’s for several projects I am working on so stay tuned for HD stuff. Thank god there’s soapbox and vimeo.
After the last update and the fact that I am locked into iTunes (using it for more than 5 years…having rated almost 70% of my huge library…) I decided to buy an iPod at the beginning of this year. Sadly there was only the big and heavy iPod classic that looked promising since the touch was way to expensive.
I thought about things like: Would I need my whole library or would it suffice to have 8/16/32 GB of it? Do I want to have additional applications or just a music player?
After the last update several things came together to a conclusion:
Since my wife doesn’t like the look of the new nano we decided to get the 16 GB Touch.
It was delivered today and I am hugely impressed with it so far. It’s what I wanted and the way I wanted it. The feature of having my podcasts and audiobooks start/stop positions synced is just fantastic (listening to the first 20 minutes on the go and the rest at home is now possible because the position where I stopped listening on the iPod is synced to the iTunes).
Did I mention that we took the engraving option?
For the real windows geek – use them when you need a soft-reboot or a force-quit from work.

Some weeks ago I came across those cool color changing LED lamps made by Philips in a hardware store. It’s a mood light with a remote control – you can even control up to 6 lamps with one remote… Oh I really do think that several of these would be great in the new office or at home.

Once upon a time I was told about that cool technology that lets you take several hard drives and glue them “together” to a single big volume. This technology was called RAID – Redundant Array of Inexpensive Disks – and that it was. It brought us greater levels of reliability and performance – and it was inexpensive compared with other technologies and since hard drive prices are falling for years and storage space is growing along with that it’s getting even cheaper than anything else you could use to store data securely. Some of us even backup to a independent RAID system.
In the beginning of this all there were several hard drive interface technologies used – mainly it was Parallel ATA and SCSI. It was widely accepted that the SCSI drives are specified for 24/7 server usage and were almost everytime faster than their consumer PATA relatives. It was accepted that if you want to build a reliable industry grade RAID you would want to use SCSI drives – the SCSI bus system even had advantages like up to 7 drives per bus compared to just 2 drives with PATA or hot-swap capabilities.
Over the last years it turned out that SATA is the new interface technology that replaces the old SCSI and PATA. There are several server grade SATA drives available now – these drives are getting cheaper, faster and bigger by the minute. So there’s not a real purpose for anything “more server than server-SATA” you might think. Again if you want to build inexpensive and redundant storage arrays there is nothing cheaper than standard or even server SATA drives. They are fast, reliable and huge.
So some years ago the industry presents: the SAS interface. It’s called “Serial Attached SCSI” and is the “new cool thing in hard disk storage”. There are some niche features that may or may not justify the existence of SAS. A fact is that SAS hard drives of the same size and speed are more expensive.
“SATA is marketed as a general-purpose successor to Parallel ATA and is now common in the consumer market, while the more expensive SAS is marketed for critical server applications.(Wikipedia)
It’s getting worse: The industry started to offer fast hard drives (15000 rpm) only for the more expensive SAS interface. The few 15k rpm SATA drives are not slower in any way than their SAS versions – but they are not widely available and all of a sudden the same price like the SAS version.
But back to the definition of RAID:
So over the years the technology made a giant leap forward and all of a sudden you find yourself using very expensive hard drives while glueing them together to giant volumes (it’s now terabytes…petabytes…). While consumer hard drives are available for about a third (at least) the price of the server version of the same drive. It seems that the widely accepted definition of inexpensive is replaced by independence. I do know that there are use cases when you want to use the fastest spinning drive available regardless of the price – but I also think that there could be affordable fast spinning drives if we shouldn’t be bothered to pay the marketing-fee that SAS brings. It’s plain marketing to make new 15k rpm drives only available for SAS and not for SATA. Marketing and nothing more.
As it turns out many industry (marketing) brains (hey, even wikipedia) are switching to a new definition of RAID. It’s now a Redundant Array of Independent Disks – which I think is a definition that could not be worse. It’s not independence we gain with the new definition.

Once again one of my hard disks died today. It refuses to get formated and reports bad blocks… It’s one of my backup drives which is normally stored in a locker and powered on only once every while.
Now it’s dead … I need to order a new one… damn.
I finally found a fix for the unspeakable mouse acceleration problem I have with MacOS X. It’s just a fact that Apple seems to have no idea how to do the mouse handling. Some people say it’s the mouse acceleration curve that apple got wrong:
“As wonderful as Mac OS X is, it has a grave defect that can have an immediate adverse impact on the computer’s usability: the way it translates mouse motion into pointer movement. For many users, moving the mouse feels unnatural because of the peculiar way that Mac OS X performs that translation. In industry parlance, the translation is called the “mouse acceleration curve.” What is a mouse acceleration curve, and how is its implementation problematic under Mac OS X?”
It’s a problem I can live with but I am not happy. With Panther and Tiger I had a solution called MacMiceCommand. But with Leopard this solution stopped working and until I found this:
“This is a GUI version of Richard Bentley’s MouseFix. (i)MouseFix is a very simple program that will allow you to regain control of the mouse acceleration in Mac OS X. Both this web page and the program copies large parts from MouseFix because he says: “feel free to take the code and wrap a nice interface round it. Be nice and make it free for everyone to use though
”"

These guys got lucky and got themselves two Surface tables:
“Yesterday, we (Amnesia) took delivery of Australia’s first two Microsoft Surface tables. We believe they were the first units to ship outside the US. Not often you get your hands on something no one else has seen, so we thought we’d share the grand opening of the boxes…”

Learn about the latest virtualization technologies with this brief and easy-to-read booklet.”
“Last week, the Indlebe Radio Telescope, situated on the Steve Biko campus of the Durban University of Technology, successfully detected its first radio source.
The Indlebe Radio Telescope is a transit instrument that operates at the Hydrogen Line frequency of 1420 MHZ and uses a very sensitive radio receiver to detect extraterrestrial radio signals.
Stuart MacPherson, project leader in Electronic Engineering at the university, said he and his students were amazed when they realised the telescope had picked up a signal.
“We had made significant changes to the receiver to increase its sensitivity. When we went in that morning to check the data, we found that it had detected a source,” he said.”
It’s unlikely to be from an unnatural alien source but if you take in account that all the equipment was built by students on the campus of Durban Universit… that is just astonishing.

It’s like lego for electronic circuits:
“littleBits is an opensource library of discrete electronic components pre-assembled in tiny circuit boards. Just as Legos allow you to create complex structures with very little engineering knowledge, littleBits are simple, intuitive, space-sensitive blocks that make prototyping with sophisticated electronics a matter of snapping small magnets together. With a growing number of available modules, littleBits aims to move electronics from late stages of the design process to its earliest ones, and from the hands of experts, to those of artists, makers and designers.”
Sometimes you’ll need the battery of your notebook last as long as possible – sometimes it’s speed that matters. With Windows Vista you can setup detailed power plans for each situation. But this options are a bit hidden under the surface.
For that matter the “Vista Battery Saver” is a tool that helps you to setup the important settings in just one window, with just one click. It even is aware of the power state of your machine – if it’s plugged in or now and so on.
It’s a free tool and you can even download it’s sourcecode. Give it a try if you’re on a mobile machine with Vista.

When I thought of self replicating machines I thought of end-of-time scenarios and a robot armies conquering the world and enslaving the human race… it’s not that bad right now but we’re getting to it… sort of
“Adrian Bowyer (left) and Vik Olliver (right) with a parent RepRap machine, made on a conventional rapid prototyper, and the first complete working child RepRap machine, made by the RepRap on the left. The child machine made its first successful grandchild part at 14:00 hours UTC on 29 May 2008 at Bath University in the UK, a few minutes after it was assembled.”
“RepRap is short for Replicating Rapid-prototyper. It is the practical self-copying 3D printer shown on the right – a self-replicating machine. This 3D printer builds the parts up in layers of plastic. This technology already exists, but the cheapest commercial machine would cost you about €30,000. And it isn’t even designed so that it can make itself. So what the RepRap team are doing is to develop and to give away the designs for a much cheaper machine with the novel capability of being able to self-copy (material costs are about €500). That way it’s accessible to small communities in the developing world as well as individuals in the developed world. Following the principles of the Free Software Movement we are distributing the RepRap machine at no cost to everyone under the GNU General Public Licence. So, if you have a RepRap machine, you can make another and give it to a friend… “
You may have heard about Levelhead – an augmented reality game made by Julian Oliver – if you did not hear about it? No problem:
“Augmented reality (AR) is a field of computer research which deals with the combination of real-world and computer-generated data. At present, most AR research is concerned with the use of live video imagery which is digitally processed and “augmented” by the addition of computer-generated graphics. Advanced research includes the use of motion-tracking data, fiducial marker recognition using machine vision, and the construction of controlled environments containing any number of sensors and actuators.”
So – Augmented reality mixes the reality and the computer graphics and creates a new reality for you. That’s a lot of theoretical…so let’s talk about Levelhead:
It’s a game where you have to move plastic cubes with printed-on patterns in front of a camera – the computer now renders a new world inside of the plastic cubes – when you move the cube, the world inside the cube moves too… it looks like this:
“levelHead uses a hand-held solid-plastic cube as its only interface. On-screen it appears each face of the cube contains a little room, each of which are logically connected by doors.
In one of these rooms is a character. By tilting the cube the player directs this character from room to room in an effort to find the exit.
Some doors lead nowhere and will send the character back to the room they started in, a trick designed to challenge the player’s spatial memory. Which doors belong to which rooms?
There are three cubes (levels) in total, each of which are connected by a single door. Players have the goal of moving the character from room to room, cube to cube in an attempt to find the final exit door of all three cubes. If this door is found the character will appear to leave the cube, walk across the table surface and vanish.. The game then begins again.
Someone once said levelHead may have something to do with a story from Borges.. For a description of the conceptual basis of this project, see below. “
If you are not amazed now? You should watch this:
The thing is – this cool game and technology will be available at the end of this month as full open-source. I suggest to check Julians site back at the end of the month at last.

Okay – the ones who are frequently using a keyboard know that they are getting faster and faster as time goes by – so it’s normal to type fast but FAST is not enough to compete in the national speed-typing contest in the states:
“Who’s the fastest typist in the land? If you’re talking about the Land of Lincoln, it’s arguably Melanie Humphrey-Sonntag, who has won the Illinois court reporters speed contest for the past three years. At last year’s event she transcribed the contest’s blazing dictation—averaging 245 words a minute—with a 99.193 percent accuracy.
That’s about 4 words a second.”
The answer is: 2 Terabyte.
“You can see physical memory support licensing differentiation across the server SKUs for all versions of Windows. For example, the 32-bit version of Windows Server 2008 Standard supports only 4GB, while the 32-bit Windows Server 2008 Datacenter supports 64GB. Likewise, the 64-bit Windows Server 2008 Standard supports 32GB and the 64-bit Windows Server 2008 Datacenter can handle a whopping 2TB. There aren’t many 2TB systems out there, but the Windows Server Performance Team knows of a couple, including one they had in their lab at one point. Here’s a screenshot of Task Manager running on that system:”
