Wirtschaftsinformatik 2007: Architekturdokumentation

Beitrag von Gernot Starke und Peter Hruschka zur "8. Internationale Tagung für Wirtschaftsinformatik", 28.Feb-2.März 2007, Karlsruhe - zum ersten Mal stelle ich arc42 auf einer internationalen (wissenschaftlichen) Konferenz vor.

Aus dem Abstract:
IT-Entwicklungsprojekte verwenden heute immer noch ungebührlich viel Zeit zur Entwicklung projektspezifischer Strukturen für die Dokumentation von Software- und IT-Architekturen. Durch die Verwendung von Strukturvorlagen lässt sich einerseits dieser Aufwand erheblich reduzieren, andererseits die Qualität von Architekturdokumentation deutlich steigern. DerBeitrag stellt die arc42-Schablone zur Architekturdokumentation vor, die sich in vielen kommerziellen, industriellen und Open-Source Projekten bewährt hat.

Ich werde das arc42-Template erstmals auf einer internationalen akademischen Konferenz präsentieren. Konferenzbeitrag von Peter Hruschka und Gernot Starke.

Bruce Schneier on "Secure Passwords"

Good ol' Bruce describes the inner workings of a Password-Recovery-Toolkit, PRTK, (although his post is titled "Choosing Secure Passwords) and how this biesty app tries to guess passwords. Interesting read - although it does not help me in remembering good passwords.

If you're security-aware, then hurry off my blog to read the full story... (but remember to come back :-)

Knipsen Sie digital?

dann könnte es Ihnen vielleicht gefallen, aus Ihren Bildern ein "Mosaikbild" zu berechnen, d.h. hunderte Ihrer Fotos als Mosaik eines anderen Bildes zusammenzubauen...

Wem das zuviel Arbeit ist, der lässt MozoDojo für sich rechnen - irgendwie cool (und kostenfrei).

Ich hab's mit etwa 1000 Urlaubsfotos als "Input" ausprobiert - nur mittelprächtig :-(
Falls Sie also VIEL mehr Bilder ihr eigen nennen, und ihren Mac auch mal einige Stunden entbehren können - nur zu...

AJAX - endlich mal eine realistisch/kritische Würdigung

Markus Eisele schreibt in der iX einen Artikel über AJAX im echten Leben. Endlich mal eine aus meiner Sicht realistische Darstellung, die über das techno-fokussierte Über-Lob hinausgeht - danke!

Think: Let the cloud of helpful darkness fall upon your apps

oh, what a great idea: Avoid the myth of multitasking, concentrate on ONE thing at a time (pretty difficult, with multiple windows open and several sources of distraction always available).

The guys from Freeverse found a simple-yet-clever solution called think (oops - for Mac only). Just add a (graphical) curtain (called backdrop) to your screen - nice thing, very useable.

Here's a list of appropriate keyboard shortcuts:

Command+Option+Return will raise Think and show its dashboard

Commond+Control+Return will re-focus on the illuminated app

Command+Option+Tab will illuminate the frontmost app - sending others behind the curtain.

One more SOA-definition: "a mess waiting to happen"

While editing our forthcoming SOA-book (german) I found a nice definition of SOA by Jim Kobielus in a Network-World article:

"...SOA also is a mess waiting to happen.
By encouraging widespread reuse of scattered software components, SOA threatens to transform the enterprise network into a complex, sprawling unmanageable mesh."

He gives this definition in the context for his call-for-governance...

JBoss -= 1

JBoss founder and visionary Marc Fleury quits his job at Red Hat (remember: the company that invested lousy 300+ million US$ in JBoss...), writes Heise (in German).

He's now both rich and has lots of spare time - I wonder what a creative, agressive and resourceful young man like him plans to accomplish next. I bet it takes less than 12 month until he's back in the OpenSource sphere. Anybody bets agains me?

On the other hand I'm sure the positive development at JBoss will continue - I'm deeply impressed with some of their products (e.e. JBoss Rules) - they dramatically improved during the last few month.

Web 2.0 in motion...

Lawrence Lessig pointed me to a wonderful video at YouTube,
explaining Web 2.0, tagging and other stuff...

great job... although the music isn't as cool as the movie...

at least: OpenUP process available

It had been announced a long time ago - but now its available: The OpenUP software development process from the Eclipse process framework project.

From the OpenUP docs:

"OpenUP/Basic is an iterative software development process that is minimal, complete and extensible."

And from the Process Framework website:

The Eclipse Process Framework (EPF) aims at producing a customizable software proess engineering framework.

hhm - what a goal...


Although the authors claim that Windows-32 is required, it works fine on Mac OS-X, at least with Firefox - Safari fails to display anything :-(

HDR-Images: high-contrast artwork for (nearly) everybody

SPIEGEL-Online berichtet über HDR-Fotografie - eine faszinierende Kombi aus
Kunst und Software. Ziemlich geniale Fotostrecken, bei flickr gibt's ganz viele weitere Beispiele. Ich mag Wat Arun at Sunset. Mehr auch im HDR-Pool.

(German) Tutorial on REST (with Rails)

Thomas and Ralf provide a (german) tutorial on implementing REST-ful architectures with Ruby-on-Rails.

Astonishing: 25Gigabyte FREE online backup storage

Today I tried out MediaMax - a pretty cool online backup and file management service. These guys offer 25Gigabyte of free (yes - free, no cost, no ads, no pain) storage - although in their free version you are only allowed 1Gig of free download per month.

I don't care - I long for offsite-backup space. And even the premium plan (4.95US$/month) isn't that expensive - and gives you 100Gig storage plus 10GByte download per month.

Their upload-applet worked in both Safari and Firefox, even plain-ftp upload is possible. Too bad that upload-speed in DSL is such a nuisance...

Another little piece in my personal backup strategy (which includes an OpenSuse powered Raid-1 subversion server, an external USB-drive, and a user-friendly interface for Unix-tar...)

Scrum Reference Card

A nice overview of Scrum - too bad it's only available as (un-scaling) gif.
