A quick review of my new Camera accessories

I just received some photo toys for my trip to Egypt next week:
The Nikon MB-D80 battery grip: Though it adds better handling (especially with big lenses), the battery grip feels pretty cheap and the shutter release on the grip is just crap. There is no “half-press-point”! I bought some AA rechargeables, though I would recommend you to just get another EN-EL3e battery, because that’s easier to handle and recharge.
The Nikon 70-300 f/4.5-5.6 VR tele-zoom: This really is a great lens. I got mine new for 350€. It may not be as fast or sharp as the 70-200 f/2.8, but it’s very sharp even at f/4.5 or f/5.3 at 200mm. With f/5.6 at 300mm image quality still seems pretty good, although it’s no longer as sharp as in the 70-200mm range.
A Hoya HD circular polarizer: This one is very well built. I actually wanted to buy a cheaper one (the HD goes for 80€ in Germany), but it’s definately worth it! They are so easy to clean. Though I don’t have any comparisation, this one only costs about one full f-stop, whereas I’ve heard that the ceaper ones cost about two full f-stops.
The Hama DustEx: just blow your dust away… I think I’ll need this in the desert.
Some Sanyo Eneloop reachargeable batterys: Wanted to use these in the MB-D80, but I think I’ll get another EN-EL3e for better handling. But these rechareables really rock! I already owned four for about a year or so, charged a couple four months ago, and my new battery charger tells me they are still at 1.39V (e.g. FULL!).
Some SanDisk Extreme SDHC cards: I buy SanDisk since almost 5 years… never had any problems. My D90 almost never stops shooting with these fast cards!
A Technoline BC-700: I is just a re-labled ELV BC-700, and so far it works perfectly well with the Eneloops.
The Moment It Clicks by Joe McNally: Well, for more than 35€ this book didn’t answer my expectations. Joe McNally is a great photographer and I really like his work, but i think the book is more about McNally’s career (a bit like an autobiography) and about being a photographer, with great images but very few explanations about the setup. Nevertheless Joe McNally has a great writing style and I got some inspirations. I think I’ll sell it on eBay when I read it again.
The Digital Photography Book Vol.2 by Scott Kelby: I didn’t read this one so far, but from a quick look at it, it’s a more technical book (what is what I wanted). I’ll read it in my holidays.
Ah hell! I still need a camera bag!!!!!
… 10 hours later … I’ve just bought a LowePro Inverse 200 AW, which is a pretty small bag. It hardly fits all my gear. I could store a flash at one of the sides, but it won’t fit the wide-angle I wanted to buy next
damn!

Call me brain
Nah just kidding… I’m not conceited! But yesterday I’ve been told my marks and they are gooooooooood
Math: 1(A), English: 1(A), German: 1(A), Biology: 1(A), Politics: 1(A)
That gives me a grade point average of uhm… *calculating* 1,0!
Hell I was surprised! I would have never expected that good marks in Biology and Politics or even German! I’m soo haappy! :p
Now I can really relax and enjoy the summer. Sadly the weather isn’t that good, but hey… I’m flying to Egypt in just 10 days. I think the weather in Sahara desert and at the Red Sea will be much better
Take care!
2009’s Virtualization Techniques Compared
Hi folks, before we get started a small explanation of my setup and why I want to replace it.
My small home server runs Xen 3.3 with Ubuntu Intrepid, a Debian Xen kernel and the guests on LVM devices. Guest OSs vary from Debian over Solaris to Windows. I built the server last year, but sadly I’m already running out of HDD space and want to upgrade soon. I also want to re-install the Dom0 because Intrepid doesn’t run very well: USB doesn’t work with all devices, there are some bugs in the start-up scripts and I have trouble with the ttys.
A lot has changed since I last fiddled with virtualization so I used this weeks bad weather to compare the current status of all those virtualization systems.
Because there are so many different needs, there are many specialized solutions for desktop and server virtualization. Open-Source, free or commercial ones.
I use VirtualBox on my workstation because it’s free, fast, easy to use and runs very very well. I’ve used the VMware products earlier on Linux and Windows until they became too feature-rich, slow and sometimes even buggy for me. But this post is not about desktop virtualization, it’s about open-source (or free) server virtualization.
VMware Server, VMware ESXi, Microsoft Hyper-V, VirtualBox, Xen and KVM are the ones I’ve tried. There is also Virtuozzo, OpenVZ, UML and so on, but these are more like chroots on steroids. Continue reading to see what I liked and what I didn’t like about them.
help.ubuntu.com links to my blog
I was just comparing the current status of KVM, Xen and some other virtualization techniques when I came across the Ubuntu Help for Xen. The page states that Ubuntu still doesn’t provide a Xen Dom0 Kernel in their latest release, but that doesn’t surprise me becaus Xen still didn’t make it into the official Kernel… maybe because everyone loves KVM that much. But they link you to a blog post which shows how to run Xen on Ubuntu anyhow.
Noticed it? Yes that’s my article. I was really surprised to see a link to my actually pretty provocative article on an Ubuntu site. They could have also linked to bderzhavets article.
So… that’s it for now. I’ll continue comparing virtualization techniques with the help of debian-user-german and will hopefully begin with the reinstallation of my xen host.
