JAMon - Java Application Monitor
The Java Application Monitor (JAMon) is a free, simple, high performance, thread safe, Java API that allows developers to easily monitor production applications. JAMon can be used to determine application performance bottlenecks, user/application interactions, and application scalability. JAMon gathers summary statistics such as hits, execution times (total, average, minimum, maximum, standard deviation), and simultaneous application requests. JAMon statistics are displayed in the clickable JAMon Report.
To use JAMon you simply plugin the jar file and:

Almost Free Text
Almost Free Text is a document preparation system. It is mostly free form meaning that there is little intrusive markup. AFT source documents look a lot like plain old ASCII text.
AFT has a few rules for structuring your document and these rules have more to do with formatting your text rather than embedding commands.
Right now, AFT produces pretty good (weblint-able) HTML, XHTML, LaTeX, lout and RTF. It can, in fact, be coerced into producing all types of output (e.g. roll-your-own XML). All that needs to be done is to edit a rule file. You can even customize your own HTML rule files for specialized output.

Skype - P2P telephony
My brother, Matthias, just told me about Skype which is an excellent (and free!) software, which allows you to do free phone calls through the internet - all over the world.
I tried it out and was really surprised about the good quality and easy handling.
What can I say more, the slogan "P2P telephony that just works" is definitely right.
Here are some features of Skype:
* Free unlimited worldwide phone calls to other Skype users
* Superior sound quality - better than your regular phone
* Works with all firewall, NAT and routers ? nothing to configure!
* Friends list shows you when your Skype friends are online and ready to talk or chat
* Super-simple and easy to use
* Your calls are encrypted "end-to-end" for superior privacy
* Based on cutting edge peer-to-peer technology developed by the creators of Kazaa and Joltid

Cocoon Day 2003
I just return from the Cocoon Day 2003 here in Vienna.
It was the first bigger official Cocoon-centric one-day workshop of this kind. It was organized - and very well to be mentioned - mainly by Reinhard Pötz and Alexander Schatten. The event gave a really great overview of the Cocoon basics, some advanced infos and best practices and not to forget many practical use cases.
Perhaps many don't even know, that many (if not all) of the speakers - which were coming from Austria, Swiss and Germany - were not paid for this.
So many thanks to them!
I'm looking forward for more such great events in Austria!

Guido's blogging again
Nice to see that Guido has found some time again to write for his weblog after a two-month break during August/Semptember.
I read some interesting news about Microsoft patents there:
* "Believe it or not, Microsoft got a US patent for Cookies. The patent has already been requested in December 1996."
* "Microsoft got a US patent on activity monitoring in IM networks."
I hope that it will not come this far with software patents in europe ...

EU Publishes Open Source Migration Guidelines
The IDA Open Source Migration Guidelines provide practical and detailed recommendations on how to migrate to Open Source Software (OSS)-based office applications, calendaring, e-mail and other standard applications.
These guidelines have been designed to help public administrators decide whether a migration to OSS should be undertaken and describe, in broad technical terms, how such a migration could be carried out. They are based on practical experience of a limited number of publicly available case studies, and cover a wide range of management and technical concerns.

Just4log
Just4log is a library to enhance dynamically the performance of various logging systems inside a java application. Dynamically because the sourcecode in java is not modified but rather the optimization occurs on the compiled ByteCode files.
It supports Log4J, Apache Commons Logging and JDK 1.4 Logging by post-processing something like this:
into this:
This way it keeps the sourcecode clean from too much debugging-related statements, while don't have to pay the hidden cost of parameter construction.
Currently it provides an ant task to do the job.
In the future you can benefit from the following uses:
* A classloader implementation allows Just-In-Time optimization.
* A command line program allows optimization from normal scripts.
* Access via a GUI.
A really useful tool!

DSPAM
DSPAM: "DSPAM (as in De-Spam) is an open-source, freely available anti-spam project. DSPAM effectively filters spam system-wide using advanced techniques combined with one or more of the supported algorithms (Bayesian, Alternative Bayesian, and Chi-Square are currently supported). A majority of users achieve filtering rates ranging from 99.55% - 99.9%, with some users reporting an actual 100% accuracy rate during long periods after initial learning. DSPAM is currently effective as both a server-side agent for UNIX email servers and a developer's library for mail clients, other anti-spam tools, and similar projects requiring drop-in spam filtering."

HEROLD Marketing CD - The next Big Brother Award?
HEROLD, an austrian company providing telephone books printed, on CD and online, want's to sell a very questionable new product: The "Herold Marketing CD private".
It contains contact information (phone number, address) of more than 4 million people and additional marketing data of more than 2 million people.
Herold says on their website:
Die HEROLD Marketing CD private wird Name und Adresse von mehr als vier Millionen Privatpersonen in Österreich enthalten. Zu zwei Millionen Personen werden darüber hinaus marketingrelevante Zusatzinformationen zur Verfügung stehen, die auf statistischen Hochrechnungen basieren.
Für den Anwender werden nur Informationen zu Name und Adresse ersichtlich sein. Das heißt, man wird nach den tiefergehenden Daten selektieren können, sich diese aber nicht zu einzelnen Personen anzeigen lassen.
Sensible Daten wie Religionsbekenntnis, Krankheiten, Blutgruppe oder Bonität sind selbstverständlich nicht enthalten.
Das Datenmaterial wurde von der dm-plus Direktmarketing GmbH erhoben, die HEROLD die Einhaltung aller datenschutzrechtlichen Bestimmungen bei der Ermittlung der Daten bestätigt hat.
Derzeit prüft die Datenschutzkommission das CD-Projekt. "Wir von HEROLD begrüßen die kritische Betrachtung durch die offiziellen Datenschützer: Sie hilft uns, in einem gesellschaftspolitisch besonders heiklen Feld nicht nur rechtlich korrekt, sondern auch allen Betroffenen gegenüber verantwortungsbewusst vorzugehen", sagt Unternehmenssprecherin Margit Kaluza-Baumruker.
Die HEROLD Marketing CD private kann nur von Firmen erworben werden. Sie wird nicht im Fachhandel, sondern nur bei HEROLD direkt erhältlich sein. Vor Verwendung der CD muss beim HEROLD Kundenservice ein Zugangscode angefordert werden, wobei der Kunde natürlich von HEROLD erfasst wird. Die CD kann nur auf dem dafür registrierten PC verwendet werden. Der Kunde verpflichtet sich, dass er die Daten ausschließlich im Rahmen der gesetzlichen Vorschriften verwendet.
Although they claim that the "deeper data" (like family status, building type, estimated bying power, number of children, ...) can not be displayed about a certain person, I doubt, that the software can't be hacked (which has been proved many times). And the data must be on the CD - otherwise you couldn't do marketing relevant queries which would make the CD rather useless.
What can you do about it?
First you can fill out a form (available as PDF) on the Herold website, that you don't want your data to be removed from this product.
Second you can spread this information to everybody you know, to prevent them from being victims of unscrupulous marketing people abusing the data on the Herold CD.
Since I don't know when the first versions will be shipped I'd advise you to do this rather sooner than later.
It's your privacy!
But I'm very sceptic that the process of removing your data will be sufficient, because according to this information on the FAQ the deletion of an entry is done through a forced update of the marketing data, which I'm sure can be prevented too, once the data has been ckracked by dubious users of this CD.
You can also get you some more information:
* Datails
* FAQ
* Hotline
What will happen?
Even if Herold is allowed to sell the CD according to the privacy law (which is presently being investigated by the austrian privacy commission) they open the door for a broader abuse and generating spam with a higher quality, than has been common until now.
I think everybody knows that SPAM IS a problem (I'm getting more than 200 spam mails every week), which has to be stopped somehow. Unfortunately there are currently no practical solutions available and this CD really doesn't brings us one step further to the right direction.
I'd wish that Herold would not only think about how gain profit whith their data but also think about the consequences which will arise from possible abuses.
And I'm sure that abuses can't be prevented - history has proven that many times!
I fear the day when you can download a decrypted version of the Herold Marketing CD from the Internet ...

Evolvica: "Evolvica is a Java Framework for evolutionary algorithms. It is the successor of eaLib, which has been developed at the Department of Electronic Circuits & Systems of the Technical University of Ilmenau, Germany from 2000 to 2002. The development on eaLib has been stopped and focuses now on Evolvica."
Noteworthy seems to be that it uses the Eclipse Platform.

OpenSource Whiteboard Systems
At the Cocoon GetTogether 2003 the attendants were using a whiteboard system (SubEthaEdit for Mac) to collaboratively take notes of the talks.
Bertrand suggested one more (Coccinella) on the Cocoon Developers Mailinglist for doing a virtual Hackathon on the first Friday every month (which BTW is an excellent idea suggested by David Crossley).
This made me have a closer look at these tools and provide a short list of OpenSource software I found.

If you wondered like me, why there was so less traffic on the Cocoon Developers Mailinglist then you might have found the reason too: Today is the Cocoon Hackathon 2003 and tomorrow the official Cocoon GetTogether in Ghent (Belgium).

Apache Agora 1.2
Stefano announced the availability of Apache Agora 1.2 (Java Applet Version) on the Cocoon Developers Mailinglist.
It's also available for download as standalone application and has a nice User's Guide.
It's a really amazing to see this great visualization of community dynamics. If you're participating to some of the Apache Mailinglists (like I do for example on the Cocoon Developers Mailinglist), you'll find yourself and how you are related to others or to the community in common.

Xen virtual machine monitor
Xen is a virtual machine monitor for x86 that supports execution of multiple guest operating systems with unprecedented levels of performance and resource isolation. It is Open Source software, released under the terms of the GNU General Public License.
The performance impacts are quite impressive - almost as fast as running on the real machine!
Nice to see, that there's some more competition to VMWare, Plex86 and Bochs.

Software tweak boots Linux in under 200 ms
According to the article "Software tweak boots Linux in under 200 ms" on LinuxDevices.com the vendor FSMLabs has tweaked a version of Linux so that it can boot in less than 200ms (time measured from power on to startup of first application).
Now compare that to the time your Windows PC takes after power on ;-)

The Design Of The Google File System
I found an interesting paper on Slashdot which explains the design of the Google file system.
A new life begins ...
Now, that most people I meet all day IRL already know it, I think it's time to announce a very happy event in my wife's and my life:
We are expecting a baby!
The calculated due date is March 21st 2004.
There's also a weblog (in german) telling stories around this happy event.
You can already see many photos and some videos of presents and ultrasonic examination (also in 3D!).
Perhaps nobody noticed that I already added the link to the blogs I'm reading a long time ago ;-)
Stay tuned there for brand new stories there!

DVD: Revolution OS
On Friday I got the long awaited DVD Revolution OS which is a very good documentation about Linux, Free Software and Open Source. There are interviews with many important people (e.g. Linus Torvalds, Richard Martin Stallman, Eric Raymond, Bruce Perens, and many more).
The second DVD contains additional interviews, "The Free Software Song" music video, a still image gallery, biagraphies, documents about free software and open source, ...
It's really worth the $22,49 I paid at Amazon and I'd encourage everybody to buy it too!
There's one drawback: I only can playback it in black/white on my DVD player, although it works on my notebook :-(

OXF - The XML Platform (and Cocoon alternative?)
Today Ricardo Rocha found an interesting comparison of the comercial product OXF with Cocoon.
It seems to provide some more features like Cocoon.
Stefano already commented on it in November 2002 and said, that their architecture would not scale. Game over.
Perhaps at least it might push Cocoon a bit forward. A little competition never hurts.
The Cocoon Wiki has a page with similar servers to Cocoon.

New Bon Jovi Album: "This Left Feels Right"
Quoting the announcement of the new album album "This Left Feels Right" from Bon Jovi:
BON JOVI are set to release THIS LEFT FEELS RIGHT on NOVEMBER 4, 2003. Co-produced by PAT LEONARD, JON BON JOVI and RICHIE SAMBORA, THIS LEFT FEELS RIGHT is a showcase of the band's greatest hits, each completely reworked from an acoustic base with new arrangements and various styles. (In addition to the Bon Jovi hits, which include "Born To Be My Baby," "Keep The Faith," "It's My Life" and "Wanted Dead or Alive," the band has included two new songs, "Last Man Standing" and "Thief of Hearts".) THIS LEFT FEELS RIGHT is not the band performing their most popular songs with two acoustic guitars. Each song has been broken down to its core elements, re-discovered and re-crafted, constructing an album that takes the songs you thought you knew in a whole new direction.
"We went into the studio thinking we were making an acoustic record," says Jon Bon Jovi. "We had a definite idea of the record we were going to make. But once we began experimenting with the songs and trying out new ideas we created a very different, unique album. We made a complete left turn and took the project down a different road. "
The band joined forces with veteran producer PAT LEONARD (Madonna, Rod Stewart, Elton John) and began the process of choosing which of the many hits the team would rework. Large rock anthems became jazzy riffs. Songs sung aloud to crowds of 80,000 morphed into intimate serenades. Tempos and instrumentations, phrasings and arrangements have been revamped and each track is as if it were a brand new song. The long hours in the studio have been some of the most creative and productive the band have ever experienced.
"I am having the most fun I've ever had working on this album," elates Richie Sambora. "I'm so excited - I literally cannot wait to get into the studio everyday and get to work."
I'm very enthusiastic about this new album, since Bon Jovi is the only band I grow up with and still "Keep the Faith" ;-).
The accoustic version of "Livin' on a Prayer" has always been a milestone of music performance history and I'm looking forward to hear the new versions of great old songs.
Definitely a must-have, if you ask me!

GNOME Storage
GNOME Storage: "Storage is an exciting project to replace the traditional filesystem with a new document store. Storage is part of a larger design for a new desktop environment, more details on that to come. The current implementation offers natural language access, network transparency, and a number of other features."
I already read about such new kinds of filemanagement some time ago.
I'd wish that KDE and Gnome join forces in that area like they did with the Free Desktop Project!

I wonder if this will have some positive effects on Cocoon?

That's definitely less verbose although I don't know if I like the curly bracket and the backslash that much ;-)

BONITA - A Cooperative Workflow System
BONITA is a flexible cooperative workflow system, compliant to WfMC specifications, based on the workflow model proposed by the ECOO Team, which incorporates the anticipation of activities as a more flexible mechanism of workflow execution.
The system provides:
* A comprehensive set of integrated graphical tools for performing different kind of actions such as process conception, definition, instanciation, control of processes, and interaction with the users and external applications.
* 100% browser-based environment with Web Services integration that uses SOAP and XML Data binding technologies in order to encapsulate existing workflow business methods and publish them as a J2EE-based web services.
* A Third Generation Worflow engine based in the activity anticipation model. This flexibility allows a considerable increase of speed in the design and development phases of cooperative applications.

OWL - Web Ontology Language Candidate Recommendation
The OWL Web Ontology Language Candidate Recommendation of the W3C has been released on August 18th.
It is designed for use by applications that need to process the content of information instead of just presenting information to humans. OWL facilitates greater machine interpretability of Web content than that supported by XML, RDF, and RDF Schema (RDF-S) by providing additional vocabulary along with a formal semantics. OWL has three increasingly-expressive sublanguages: OWL Lite, OWL DL, and OWL Full.

It has about 330 pages and shows you the practical side of RDF.
I'm not a very fast reader, since I only read such books when I've got some time on the week ends or on holidays. Today I got to page 6 then I had to jump into the pool because of the hot weather ;-)

Gmane - Mail To News And Back Again
Gmane is a very nice mailing list archive with many features. One I really like is the threaded view to easily follow discussions!
oreilly.com: Practical RDF
O'Reilly published a new book: Practical RDF.
It explains RDF from the ground up, providing real-world examples and descriptions of how the technology is being used in applications like Mozilla, FOAF, and Chandler, as well as infrastructure you can use to build your own applications.
(I already reserved my copy at amazon.com ;-)

Wedding and wonderful honeymoon
Yes, we finally married!
Originally Maria and I were afraid from this step as we both hate big celebrations. Nevertheless it was the most beautiful day in our life.
To some part that was due to the fact that we didn't want to have a traditional wedding. Instead we wanted to have it the way it fits best to us. I'm sure we hadn't got so much positive feedback afterwards if we followed every hint about how we should do it ;-)
Now some more infos:
We married on July 19th (the 25th birthday of Maria) at the registry office in Wieselburg (15:00) and afterwards (with some drinks and photos in between) at the church in Neumarkt (17:00).
Theb we had some time to talk to friends, relatives and neighbors while having a drink and something to eat.
After that we drove to the Mostlandhof, where we had an excellent dinner. This restaurant is located on a hill where you can overlook beautiful parts of the Erlauftal. The weather was excellent and we could enjoy a really beautiful sunset.
At about 24:00 we were taken to a quite new Hotel in Amstetten, called Exel, where we spent our wedding night.
On monday at 02:15 early in the morning a bus catched us and brought us to Venice (Venedig for german speakers ;-). There we got onto the ship Costa Classica where we had a wonderful one-week cruise: Venice - Bari - Katakolon/Olympia - Santorin - Mykonos - Rhodos - Dubrovnik (Croacia) - Venice.
I never imagined that our wedding could be so beautiful.
Here I'd like to say thanks again to the parents and grandparents of Maria for making us such a big present with the Hotel and the cruise.

Hard week, no entries
This week was really hectic because bad things always happen just at that time, where you have other important things to do.
Somehow we managed most of the problems (surprisingly fast unlike originally expected) and therefore our 3-day advanced Cocoon training held by Guido Casper could take place without major interrupts. It completes the training of some weeks ago held by Matthew Langham, where he taught us the foundations of XML and Cocoon.
After these three days I have the feeling that Cocoon is like a big surprise box where you can take out presents as many you like and everytime you think now it must be empty someone else pulls a new present out of it.
Guido really did a great job at teaching us the Cocoon internals and different form frameworks without taking too much influence on our decisions and staying objective about the pros and cons.
I'm looking forward to work with you on our project and bringing it to a great success!

Happy Birthday Grandpa!
My grandpa turned 69 today and my grandma will be 70 on the 24th of June.
He always told me that computers are something that he'll not understand anymore.
Now he uses computers to write letters with Word, do calculations with Excel and compose music with Sibelius.
Some time ago he told me, that computers are ok, but he's too old to understand the internet...
Guess what!
Now he uses Google to search for information, writes emails and wants to do telebanking with his 56k modem.
I'm sure it won't take long 'til he has a highspeed internet connection.
He's really an interesting person who has many interests and is in many ways like me. He always want's to know what's behind it and doesn't hesitate to put much energy into findig out himself.

Time to marry
Christian Haul announced on the cocoon developer mailinglist that he'll marry his girlfirend today.
These were his words:
Hi team.
I will be offline 'till ~12th (and largely have been for some days already)
due to some happy event in my life: I'm going to marry my girl friend tomorrow!
Chris.
Many people congratulated him, and I thought it was time, to "out" myself too. I did so while sending my congratulations to Chris.
Here are some more details about our wedding:
Maria and me live together for 6 and two-third years now and we will marry on July 19th in Neurmarkt/Ybbs (Lower Austria, Austria, Europe, Earth ;-). This date is not chosen by accident, because it's the 25th birthday of Maria and we decided it while enjoying a wellness weekend at Therme Geinberg in end of May 2002.
Those of you who've read my FOAF profile (viewable with FOAF Explorer) perhaps noticed that I've already silently included our wedding event some time ago.

Tomcat Clustering Models and Implementations
The OSCOM session about "Tomcat Clustering Models and Implementations" on July 9th by Jason Brittain looks very interesting. Unfortunately I can't be there.
But the little information on the session description page was enough for me to recognize the possibilities you have for clustering tomcat. Very nice, if you just want to have a brief overview about the possibilities.

JBoss 4 Developer Release 2
The JBoss Group has released JBoss 4 Developer Release 2.
This is a list of recent changes:
* JBossDO: JDO for transperent persistence for POJOs. First iteration from the hard work of Alex Loubyansky.
* JMS rewrite: First iteration from Nathan with help from Bela Ban and Adrian Brock. P2P serverless topics by way of reliable multicast.
* AOP XDoclet integration: Great work from Andy Godwin. JSR-175/C# metatags right now in JBoss 4!
* Expand AOP Pointcuts: Per method, field, constructor as well as Caller pointcuts.
* AOP Performance Improvements: Framework speed up by factor of 6.
It's really amazing what the AOP framework aims to solve. Let's hope, that it holds what it promises. But what's going to happen with all the J2EE standardization? Will all the extensions that JBoss brings you lead to incompatibility or will it merely drive the J2EE standardization process. In the later case would not then JBoss define the state of the art and all other application servers try to do the same?
I'd be really interesting in your thoughts on this topic, unfortunately I have no comment functionality on my weblog. But there are enough places where you can post your JBoss comments (The Serverside).

RSSCreator.class.php - bitfolge.de
RSSCreator.class.php is a PHP-based class to create RSS-feeds for the versions 0.91, 1.0 and 2.0.
Perhaps I should use this one instead of the old hand-written RSS-feed creator of our website at work.

Weblog of Lars Trieloff
Lars Trieloff has mentioned some interesting links (1, 2) on his weblog:
* A german tutorial about DocBook
* ArgoFMC, a plugin for ArgoUML, enabling you to draw FMC diagrams. It is heavily based on a tool named ArgoPNO.
* Apache Modeling Portal
He also sent me a mail with a link the following tool to do manual trackback pings (see posting from yesterday):
* Simpletracks
Thanks again, Lars!
This makes manual trackback pings much easier ;-)

How to do manual trackback pings
I'm just figuring out how to use trackback.
Unfortunately blogger, the weblog provider I'm using, does not support trackback (neither direction). So I want to ping other weblogs 'by hand' and therefore I have to learn how to do that.
I've found these resources so far:
* TrackBack Explanation (Movable Type)
* TrackBack Development (Movable Type)
* Movable Type User Manual: Trackback
* How Trackback Works
* The Next Generation of TrackBack: A Proposal
The first manual try of the first article failed although I got a successful response.
The second try with the second article succeeded but - stupid as I am - I've chosen the wrong article to ping.
But the third try with the third article was finally perfect ;-)
As you see, doing trackback 'by hand' is really possible but is really painful and error-prone. If you have a blogging tool which automatically supports trackback, please continue using it. You didn't miss anything ;-)
BTW, does anybody know, how it's possible to - at least - ping trackbacks on other weblogs based on your blogger-based weblog?
Help is very much appreciated!

Knowledge Sharing vs. Knowledge Hoarding
There is a very interesting article on thought?horizon which explains how knowledge management can be successful and more important that you get much more in return, if you share your knowledge instead of hoarding it.
I totally agree about this!

FoaF/RDF/RSS Tools
MFD Consult has some nice Online Tools available.
1. FOAF-related:
* sha1ify
* Add New Friend
* Topic Finder
* FoaF Explorer
2. RDF-related:
* Weather Information as RDF/XML
* RDFS Explorer
3. RSS-related:
* Syndication Subscription Service
I've already mentioned the FoaF Explorer some time ago.
All of these are really interesting tools if you want to learn how the technologies around the Semantic Web are working.

New Morphon XML/CSS-Editors available for free
Morphon Technologies has made available Morphon XML-Editor 3.1 and Morphon CSS-Editor 1.3.6 available for free today.
Both are written in Java and run therefore on a wide range of systems.
I'm just downloading it but it's damn slow. Perhaps their server wasn't prepaired for the load after giving it away for free ;-)
I'll tell you more, when I was able to try it out!
Update:
I could now have a look at it and have to say, that it's really worth a try!
It uses an CSS-based WYSIWYG editor to edit your XML files.
I've tried it out with docbook and it really looks great!

Metadata for your Blog!
I found some interesting meta tags on Eric Vitiello's site called Perceive Designs which allows you to put even more semantic information to your weblog. Examples are some geographic information, dmoz IDs and autodiscovery of blogroll OPML files.
I've included them into my weblog, so have a look at the quite growing header of the HTML source, if you're interested.
Here are some useful links, which helped me to include the right meta tags:
* Metadata Help on Syndic8
* TGN - The Getty Thesarus
* DMOZ - the Open Directory
* GeoTags - GeoTags
* List of Meta Tag values at Bauser.com
I'd encourage everyone to put all this valuable information into their own websites. That's the foundation to build tools which make use of this information!

Some cool FOAF viewers
Here are some online FOAF viewers I've found with an example link to view my FOAF profile:
* FoaF Explorer (my FOAF profile with FOAF Explorer) lets you explore a given FOAF file. Has a nice interface, which also shows you the photo, if you have set one in the FOAF file ;-)
* FOAF Web View (my FOAF profile with FOAF Web View) has a spider to which you can add your FOAF file. Then you can navigate through the network of who knows who. - Quite interesting!
* FOAFNaut can generate SVG images from a network of people who know each other.
* FOAFBot is a bot which you can ask some questions about persons and he gives you the answers.
Somehow I get pretty addicted to the possibilities, the RDF-based technology gives to you ;-)

RSS News Readers
Matthew has recommended the RSS news reader NetNewsWire with a three-paned-interface for Mac OS X on his weblog.
Unfortunately I don't have a Mac, but want to use something similar under Linux or Windows I did a query on google.
That's what I found:
* This list of RSS Readers (RSS Info) is from Blogspace.com
These are the one's I liked most:
* amphetaDesk is (open source, cross platform)
* Beaver (.Net)
* clever cactus (Java)
These are online services:
* Meerkat
* NewsIsFree
* RSS News Reader
Other Utils:
* RSS to Email Aggregator

New Cocoon Portal Engine
Just played a bit with the new Cocoon Portal, which will be in version 2.1 and have to say, that I'm really amazed!
I did not see much of it yet, but what I saw I liked a lot: I integrated my weblog into the portal and discovered, that you can control the coplets in every way you like.
E.g. you can set up content syndication with a life feed of a weblog, can control if you want to buffer the content and can even give an error URI, if the life newsfeed is not available.
Integration of my weblog including learning the portal and creating an XSL stylesheet for it was done within one hour!
I believe this will make our work so much easier ;-)

Google Toolbar 2.0 beta with BlogThis!
The newest version of the Google Toolbar for MS Internet Explorer has some new features (Popup Blocker, AutoFill, BlogThis for Blogger - you know, that Blogger has been bought by Google, no?).
I wonder what's happening to the Internet Explorer, after MS decided to not distribute future versions without an operating system anymore and leaving the development of such common things like popup blocking to search engine providers like Google? hmmm...
Honestly I don't really care, since I'm quite happy using Mozilla, Konqueror and Opera. IE sees my desktop only if I have to and I can assure you, that's not often ;-)

Report of the Cocoon Stamtisch
It was really a nice evening yesterday which started at 20:00 and took until 00:40 for the toughest ones (Reinhard, Manfred and me ;-)
It's really amazing, how such events help to realize that people often develop the same things at work which you're going to do.
Perhaps we'll join our effords on certain areas in the future.
Matthew had to get off a bit earlier to be well rested, because he should do some Cocoon training for us today and tomorrow ;-)
I can't tell you that I am well rested :-(
I can't await the next Cocoon Stammtisch and perhaps some other Cocoon events will take place in the near future in Vienna, but I don't want to spread vapor now.
So stay tuned!

Cocoon Stammtisch in Vienna
Today I'll go to the Cocoon Stammtisch in the Centimeter I (Vienna).
According to the mailing list, there well be about 15 persons.
Matthew Langham, who will do a Cocoon training for us the next two days, is coming too.
This is my first Cocoon community meeting, so I'm a bit excited ;-)

Completely BlogRolled Sidebar!
Thanks to the excellent support of BlogRolling I even can manage the complete sidebar (yes, even my buttons! - except the weblog archives of course) within BlogRoll. No need to fiddle with HTML code anymore! Now I can add new links with just a mouseclick while surfing the web :-).
It has some more features (like making liks available in RSS, OPML, for PHP or via JavaScript), which I'll investigate in the future.

Now BlogRolling!
All links on the sidebar (except the buttons, since I don't know if it's possible) are now maintained via BlogRoll.
This allows me to maintain the links much easier and gives me the possibility to show you some backlinks ;-)

Heavy Storm
10 minutes ago a really heavy storm suddenly arrived here in Vienna. I had to close all windows to prevent some damage. Like you know it from the movies, I saw a deracinated bush and many other things crossing the place in front of our house 8-[.
Enriching my Weblog
Erik C. Thauvin (The Truth is Out There) inspired me to enrich my weblog with the following thingies:
* Add a FOAF RDF description of me including a button for it
* Add BlogChalk Metadata including a button and the BlogChalk text on the bottom
* Make it kown as Java Weblog and add button for it
* Added a suitable Creative Commons license
* Add a FOAF RDF description of me including a button for it
* Add BlogChalk Metadata including a button and the BlogChalk text on the bottom
* Make it kown as Java Weblog and add button for it

Blog Buttons
I found some very interesting resources in the web regarding uniform style buttons for weblogs.
Here are they in the order of navigational discovery:
* Nifty Icons
* Archive of blog buttons
* MetaFilter blog button announcement
* Jeremy Hedley is the author of these buttons
* And here's a button maker to create one yourself
I didn't look for them without a reason.
Now you can enjoy these buttons on my weblog :-)
If you want to use them yourself, I've put together two ZIP-files of 256 blog buttons as GIFs as PNGs.
Additionally I've added my BlogChalk.

I didn't look for them without a reason.
Now you can enjoy these buttons on my weblog :-)
If you want to use them yourself, I've put together two ZIP-files of 256 blog buttons as GIFs as PNGs.
Additionally I've added my BlogChalk.

RDF day @ freshmeat
Seems like yesterday was the RDF day at Freshmeat.net with 4 RDF-related posts on one day!
The first one I recogniced (Joseki) I've already mentioned below.
Here are the other ones:
* IsaViz is a visual authoring tool for RDF
* Jena is a semantic web toolkit
* sesame is an Open Source RDF Schema-based Repository and Querying facility.
It's really nice to see that the semantic web is going further every day!

Joseki
Joseki is a server for publishing RDF models on the web. Models have URLs and they can be accessed by query using HTTP GET. It is part of the Jena RDF toolkit and provides a coarse-grained web API that is based on extracting a subgraph from the published RDF. The extracted RDF can then be processed locally with the fine-grained API provided by Jena.
Sunday ice cream walk
My girlfriend, Maria, and I did again our loved walk from Volkstheater (where we get off from the line 49) to the ice cream parlor at Tuchlauben (if you speak japanese or just want to look at some photos you can have a look at this japanese page ;-) where you get the best nougat ice cream I know, passing by some beautiful buildings (Natur-/Kunsthistorisches Museum, Heldenplatz, Hofburg, St. Peter's Church) of Vienna.
If you ever come to Vienna in summer I really recommend to visit these places (among some others of course ;-)!

Blog Polishing
I just did some polishing on my weblog which is reflected by some new buttons at the bottom of the left sidebar.
The site is now valid XHTML 1.0 Strict and contains valid CSS2 which you can check yourself.
Additionally I've added buttons for the RSS feed of my weblog, a button for subscribing this weblog with the Radio Userland client, a GeoURL-Button where you can find blogs located near me and a button to my BlogShares account.
Enjoy!

XMLStarlet Command Line XML Toolkit
XMLStarlet is a set of command line utilities which can be used to transform, query, validate, and edit XML documents and files using a simple set of shell commands in similar way it is done for plain text files using UNIX grep, sed, awk, diff, patch, join, etc commands.
ReadySET - Ready-to-use Software Engineering Templates
ReadySET is an open source project to produce and maintain a library of reusable software engineering document templates. These templates provide a ready starting point for the documents used in software development projects. Using good templates can help developers work more quickly, but they also help to prompt discussion and avoid oversights.
This is yet another interesting new project at Tigris.org, the excellent platform directed at collaborative software development.

Do you know an intermediate web page description language?
I'm searching for an XML language, which allows you to describe web pages/portals in a very high abstraction level.
I need it for transforming different data oriented XML schemas to an intermediate representation which is in turn transformed to the final ouput format (html, wml, pdf, ...).
Here are some requirements for the language I'm looking for:
* High level abstraction of portal elements (e.g. menu, ads, search field, logo, registration area, content area, forms, actions, ...)
* Presentation neutral description of content elements
* Embeding of different namespaces
* Prevent to write transformations from every data oriented language to every presentation format
Here's what I found so far:
Data oriented:
* News Industry Text Format (NITF)
* NewsML
* PRISM
* DocBook
* Cocoon/Forrest Document DTDs
Presentation oriented:
* (X)HTML
* XSL:FO (for PDF, ...)
* WML
Presentation independent:
The following only satisfy my needs partly:
* XHTML 2.0
* Forrest site.xml
* Forrest Book.xml
* ? (if you know some standards or drafts which fit in here please write an email to the address 'andreas dot hochsteger at oeamtc dot at').
It's really curious, that I could not find something similar, since I think it was quite common to transform data into an intermediate format and this intermediate format into the needed output format instead of transforming from every data format into every output format directly :-|

Code Generation Library
Code Generation Library is a powerful, high performance and quality Code Generation Library. It is used to extend JAVA classes and implements interfaces at runtime.
Sounds very interesting.
I found the link on the cocoon developer mailing list.

Persistent URLs
Persistent URL allows you to create persistent URLs by providing an intermediate resolution service.
I've seen using it for many XML namespaces (e.g. Doublin Core, RSS).

Modified Style
Did some finishing of the just chosen style with respect to spacings and font sizes.
I think I'll leave the standard color for a while until I get sick of it ;-)

New Style
I just noticed that the Blogger Pro software has been upgraded to a completely rewritten version with the code name Dano which provides some new features and will do so much mor in the future.
As a result I was able to change my old weblog style (which I never really liked that much ;-) to the style "Sand Dollar" which has been created by Jason Sutter.
Perhaps I'll do some customizations in the future (smaller fonts, other colors, ...) to fit my personal taste.
I hope you like the new style too!

Sapia Vlad - Open Source Validation Engine
Sapia Vlad is an Open Source validation framework. The rules can be specified by an XML syntax.
Perhaps that's something we can use at our project at work ;-)

IDE plugins for Subversion
It seems that support for Subversion in IDEs is gaining more interest and is becoming more and more usable.
I just found the following projects:
* Subclipse for Eclipse (at SourceForge)
* Svn4Eclipse for Eclipse (at Tigris)
* Svn-Up - pronounced: Seven-Up, for IDEA (at Tigris)
I can't await using the full power of Subversion for everything I'd need version controlling!

Aegis Software Configuration Management System
Aegis is a transaction-based software configuration management system. It provides a framework within which a team of developers may work on many changes to a program independently and Aegis coordinates integrating these changes back into the master source of the program, with as little disruption as possible.
I found this quite interesting project in the current issue of the german Linux Magazin.
It seems that it can use different RCS backend systems like CVS for example. An integration with Subversion would be the Perfect Solution (TM).
Let's see what the future's bringing us ...

xmlTRAM+: Using XML Technology to Manage Software Requirements and Architectures
This paper describes xmlTRAM+, which is another way using XML technology to manage software requirements and architectures.
I don't know, if there's something usable available - at least I didn't find anything.

Selected Software Engineering Books
Jason E. Robbins has a very good page with selected software engineering books.
They are grouped by the different stages of software engineering (requirements, configuration management, design, testing, ...) and provide a very good overview.
Check it out!

Bon Jovi concert in Vienna, Austria
Yesterday I was at the Bon Jovi concert in Vienna, the best band on god's earth!
I took some poor pictures with my smartphone. I don't know yet, if they're worth it to publish here.
Nevertheless it was yet better than the one's I've seen before.
They started at 20:30 and played until 23:10, started with classics like Like "Livin' on a Prayer", "Wanted Dead or Alive" and moved on to the newer songs like "Joe", "Everyday", "Misunderstood", ...
I look forward to the next concert.

Free SyncML Implementations
Finally I found something to test the SyncML capabilities of my new Sony Ericsson P800 Smartphone ;-)
* http://sync4j.sourceforge.net/ (has JBoss support)
* Do you know some more? Mail me!
Let's see, if I find a better way to synchronize all the PIM applications I'm using (P800, Outlook, KOrganizer, KAdressbook, Mozilla, ...) both at home and at work.
