There is nothing in particular that I feel I need to write about. I rather write comments on other peoples Blogs or, if there's really something that needs to be expressed by me ( 1:6.5 Billion People) - I'll write an article or a book in the future.
Saving you precious time.

My rating: 2 of 5 stars
Wonderfully printed, easy to read, marvelous to look at, pretentious piece of quack.
It was hard to pass the Introduction and the first Chapter, when you hear the author praising himself, his own importance and why literally 'everybody' in science and why science itself is 'wrong' and did not 'see' what very self-aware author sees, but nobody else.
The book is a massive piece of rarely to find print. I was self-published by the author to assure the quality of the printing. It has many black-and-white Illustrations and pictures to accompany the text. The text, when it is not about self-praising, is rather easy to read and easy to understand for non-academics. So what is it about?
It talks about the 'big' picture in nature and science. Stephen Wolfram is a well known 'Wunderkind' in theoretical physics. He made his PhD in 1979 at the age of 20. In the mid-1980s he founded Wolfram Research Inc. and invented 'Mathematica' the leading software for technical computing and symbolic programming.
Wolframs main thesis of the book and the solution he offers are easy to understand:
"... very simple programs produce great complexity. For all it takes is that systems in nature operate like typical programs and then it follows that their behavior will often be complex. And the reason that such complexity is not usually seen in human artifacts is just that in building these we tend in effect to use programs that are specially chosen to give only behavior simple enough for us to be able to see that it will achieve the purposes we want" page 3
This is the crux of the book, there, luckily on page 3.
If you read the 12 Chapters (846 pages plus around 250 pages of notes and additional massive Index, than it is most likely, that you do it because you like an intellectual exercise or because you love books and don't mind the many times annoying voice.
I am not going to discuss the results of such a vast amount of research and work that went into proving and verifying his idea. There are plenty of scientists from his fellow theoretical physics to mathematicians and others that reviewed and challenged Wolfram's book over the past years. There is even a great discussion a the slashdot-forum that mocks the authors writing and is funny and hilarious to read for nerds like me. May reviews and articles are online and it is easy to find them, if you want to.
Beyond the Masters Voice, this is a lovely book to look at. An artifact in these times of trash-quality publishing. It is not a masterpiece of printing. You cannot compare it with bibliophile editions. But for science books, if you have seen a physical copy of it, it is more on the upside, which tells you where we are nowadays, when it comes to print.

How many artists do you know who write their own newsletter to their fans? I don't know many. Actually I know only one, and that's Holly Miranda.
After her Tour with her Band Members (incl. Marques Toliver) and AA Bondy she is finally back home and had some time to upload pictures from the tour and write a newsletter.
She will perfom in New York on July 25th @ 92y tribeca with Joan As Police Woman! She wrote "(holy crow.. seriously)".
So, if you are in NYC or in Jersey or Upper NY or ANYWHERE in America, go and GET YOUR TICKETS NOW!
It's $ 15 bucks, which is ridiculous! That's as much as a parking tip in L.A. or a 2 frappuchinos.
Don't miss it, because I sadly have to. Sucks to live so far away...

on flickr and photography
I want to resent the idea that everyone who goes into a shop and buys any camera is a 'Photographer'.
I have no problem with people being able to click on everything they see, or make as much pictures of their babies, dogs and cats or trying to be creative.
I don't care if people run around through cities and make snapshots of everything in their way, never taking the time to really 'see' the things infront of them, to 'understand' them. Their choice. (of course, sometimes the 'right moment' dominates everything, granted - I am not talking about these).
There are always several angles to photography, every path is valid.
Some people love baby pictures, because they love babies. The see cute babies in pictures and say: "that's a great picture"
Only cranky scruffy old chaps like me would feel the urge to open their mouth and object by saying: "This is not really a great picture"
I had friends who are professional 'old school' photographers. They used to think about and prepare for weeks and months for a shooting or sometimes even for 'one' shot.
And afterwards the result was still unknown because they of course had to go to the dark room, working for hours.
Photography was an undisputed 'art'-form as well as it was craftsmanship.
Depending on your own possibilites and capabilites people can or cannot do 'these' sort of pictures. I want to think that professional photography is still in it's own league. It takes years. It takes maybe decades to reach a point. And sometimes you even loose your craft.
I wish people would be willing to see beyond the amazing technology inside the modern cameras and judge the result on the simple question: "What did 'you' (actually) do, to make this photo look so amazing?"
I never bought a camera in my life, because I know, I am not a photographer. Don't think, this would make my arguments less valid. I do love the old Hasselblads and Leicas etc...

Through the last 35+ years I used notebooks of all kinds. Think of Ralph Finnes in 'The English Patient' and his copy of Herodotus. I was never occupied by diary-alike 'me-me-me-blogging', but mostly wrote down quotes, equations, diagrams, some ideas to follow up on (by writing articles, essays or books - which I successfully avoided), and some quick drawings.

GParted is the Gnome Partition Editor application.
"A hard disk is usually subdivided into one or more partitions. These partitions are normally not re-sizable (making one smaller and the adjacent one larger). The purpose of GParted is to allow the individual to take a hard disk and change the partition organization therein, while preserving the partition contents."
1. resize MS Windows 7 partition
2. resize MS Windows Vista partition
3. resize Extended partitions
4. resize ntfs and win32 and ext4 partitions within the Extended partition
The only thing you have to be aware of as a user, if you do this, is don't delete any partition. You don't want to restart any OS after the resizing and let them have a hiccup.
Start the GParted Live CD and choose one step after the other in a logical, sequential style.
1. Make a logical partition smaller, so you can make other partitions larger (yes, stupidly obvious, but nonetheless I said it).
2. Move the other logical partitions to make room for the primary partitions.
3. resize the extended partition
4. resize the 2nd primary partition (make it bigger).
5. move the 2nd primary partition to have room for the 1st primary partition.
6. resize the 1st primary partition (make it also bigger).
At the end, all tasks were performed by gparted without any problem. I restarted Linux Ubuntu 9.04. Grub in the Master Boot Record was still untouched as was the /etc/fdisk, of course. The fsck starts automatically and should find no problems.
Then I started the Windows bootloader (grub chainloader+1) on the 1st primary partition. Windows 7 did a NTFS check and that was all it had to do. Windows Vista was replaced in this scenario, so it was necessary to use the Install-CD and start the 'repair'-function which also did it's job automatically. It scanned and checked it's own partition (hd0,1) that was moved and resized and it also checked the ntfs and win32 partitions on the extended partition. After two reboots, all done.
Conclusion: GParted did it's job flawlessly resizing and moving partitions in a complex scenario (ext4, ntfs, win32, primary, ext-log partitions). MS Windows 7 and Vista played along with the resizing and relocation as well, which surprised me a little bit. Well done. Linux? Ubuntu? You guessed right...

I have three different audio-chips on my pc (onboard, pci-soundcard, hdmi-audio-output on the graphic card).
Right now, the Realplayer is set to Alsa, Pulseaudio is running too and it all works fine with the pci-soundcard. I will post a real Howto, when I find the time. Until then, don-t give up. Google further, if you are looking for help, but be assured, it will work.
Here is what you can do:
* Tweet directly from TweetDeck
* Stay up to date – view all new tweets in real-time
* Use columns to create your personal dashboard
* Create Groups to easily follow friends, colleagues or other interest groups
* Update Facebook and follow your Facebook friends
* Follow topics in real-time with saved searches
* View @replies and direct messages and manage your conversations
* Never miss an important tweet with notifications
* Share your photos and videos with Twitpic and 12seconds
* And many more Twitter favourites including Stocktwits, Twitscoop and all the most popular URL shortening services
But before you go there you should listen to this little advise: FIRST DOWNLOAD ADOBE AIR and install it (I assume you know how) and only then you can click on the "Download" button, which will allow you to install this application.
I had to figure it out myself, but want to spare you the time.

the aticonfig --buildpkg
So while I had some hard-lockups when using the 3D-acceleration, when I turned off the fancy Desktops-Effects, everything became fine. I have to see if it has to do something with the overlay-mechanism, since I catch this hardware-cold only under certain circumstances (i.e. switching video into fullscreen).
But instead of looking to find the bug, I thought, I would rather write about it. After all. If you don't care about fancy wobbly windows and rotating cubes, you are fine. The question is, why would you want a Radeon 4670 at all?

"Think before you click."
Status quo: Face the facts: You will never be secure browsing the web as a normal user. Just forget the idea. If you do not establish a trusted, certified, encrypted connection, that is monitored and has to verify each packet or hash sums of it, you are always exposed to attacks of all kinds. What you still can do, as a user, is letting go of old thinking and accept the facts.
Browse the web without having to fear that your data on your harddrives are exposed to attacks. Hiding partitions, encrypting your home/user-file-directories should be recommended, but you don't have to if you follow the concept below:
the most recent Knoppix DVD is 6.1 - I like the artwork for 5.3 by Thomas Saur (?) heise.de
Howto do it: I use a Knoppix(Debian)-Live-DVD. You can install the complete Operating System on a 4GB-USB-Stick and have even 1GB left on it, for a encrypted read-only home-partition, where you can store your configuration. You can use any Linux-Live-CD (Knoppix/Ubuntu/openSUSE/etc...). Your harddrives are in read-only mode. You can make them invisible if you have not already encrypted them.Beware: there is still the chance that somebody will read your tmp-files/ram etc. Every communication between you and a server and/or service on the web is as secure as the protocols underneath allow it to be. If you can, use secure protocols all the time. If you can, use encryption all the time. But the vulnerability you offer, is way lower than surfing from your 'installed system'. If you want to download files, simply use an extra partition, where you can dump that stuff. (Run multiple scan's on these downloaded files before you read/execute them. Be aware that all scenarios which include transactions of data through the net are still open to attacks (passwords in clear text, non-secure protocols between client and server, etc...) - avoid any online-service that does not use secure protocols, encryption or other form of trusted computing. Minimize the risks.
Security vs. Convenience - it always comes down to the following question: "How much time are you willing to spend vs. how much risk are you willing to take?" Most people don't know the risks and they don't want to know.
After you finished your web-browsing everything you might have catched throughout the session will be deleted on your side (but 'phishing-attacks' during the session might still have taken place). Think of your use of the internet as a jump into radioactive waters (FALLOUT 3). Don't be online all the time. Be aware that you are open to malicious attacks. Yes, Microsoft for example, improved their default security options a great bit. Vista and more so Windows 7 offer very good measures for unexperienced users. Still the biggest threat to a 'normal user' is the notion to lull them into coziness. Neither Microsoft, nor Anti-Virus-Software, nor Mac or Linux will save you from malicious attacks.
Conclusion: This concept does not apply to all circumstances. Homebanking is as insecure as it always was. PIN/TAN and even iTAN transactions have been exploited. "HTTPS" sounds nice, but do you really now that the DNS-Server sent you to the 'real' MyBank-Website? Fake certificates are no prob for the net-mob. Your beloved Outlook or MS Office has to struggle through Wine if you really, really think you need it. But if you are paranoid (like me) or don't want to hassle with attacks that might infect your PC (even under Linux) or Anti-Virus-Software which has it's own vulnerabilities (been late, false negatives, etc), I figured, this is the best way for web-browsing.
Disclaimer: This does not work for 'safe surfing' (your kids web). This does not work for System-Administrators. They have to maintain networks and 1000s of connected computers, with infected programs and corrupt data floating around. They are mandated to use AV-Software and they better do. The nightmares of professionals is another story.

First Computers: Apple II, Amiga 500, Commodore64, x86 since 286 and Dr-Dos, Linux since Kernel 0.99
Origins: born 1967 in Munich, Germany - my Mother migrated after World War 2 from Yugoslavia to West-Germany.
I graduated successfully with something called ("Mittlere Reife") at an absolutely insignificant german school before actually starting 20 years of studies on my own, outside the institutions. I was regularly visiting the libraries of the LMU and TUM (mentioned in Thomas Pynchon's" Gravity's Rainbow"), secretly attending some lectures at these two main universities, without being a student.
I also spent around 15 years regularly visiting the Technical Library of the Deutsche Museum (where Einstein was a fellow before the Nazis kicked him out) and the BSB (amongst the world largest libraries, with a huge collection of academic magazines).
At the same time, I earned my living with low-income jobs, mostly in retail, while studying and socializing with my student-friends at night.Later on, I quit my job and lived unemployed for several years - even being homeless and having no legal papers.
I have 25 years of computer experience in my blood. I worked the last ten years in it-consulting, telling small businesses what hardware to buy, what software to use, setting things up and running, aquiring people to work as admins or to write apps for the clients.
Before that, I worked ten years in book-retail. The last employee-gig was 7 years for a book-chain (think of Barnes-n-Nobles of Germany). As an assistent-manager I was responsible for sales of computer-books and software. I made a revenue of US-$ 2 Mio for the company per year.
I started reading philosophy - besides science-fiction books - at the age of maybe 11 or 12. I use the word 'philosophy' in the broadest sense - I was reading everything, I could get my hands on: from the history of philosophy, the philosophical models, to mathematics, scientific models, methodology, biology, logic, political theories, sociology, neuroscience, physics.
interested in: scientific research: from genomics to quantum physics,
(computer) architecture/languages, parallel computing, functional programming, grid,clusters,cloud-computing,
