Bei einer kleinen Radtour wieder einmal erkannt, wie schön die Gegend zwischen #Bonn und #Köln ist. Besonders die Höhenorte des Vorgebirges mit vielen #Landschaftsschutzgebieten (Naturwälder, Maare), Pferdekoppeln und Weiden sind ein Traum.
Frühe deutsche #Grafik-taugliche #Rechnersysteme waren übrigens die von #TriumphAdler, etwa #TA #AlphatronicPC von 1985:
2000-2001, we developed the first web based mobile #GUI for the #X400 dinosaur 😆 .
The screenshots show it on early #WindowsMobile and #PalmOS.
#ISO #X400 #MHS (Message Handling System). What an anachronism.
1999-2000, we implemented the #PCT (Protected Content Type) Standard that was basically equivalent to integrity protection an digital signatures w/ X.509 certificates in S/MIME.

Legendary #UNIX paper by #DennisRitchie and #KenThompson explaining #OperatingSystem principles which are still valid as of today:
Weitere #CraftBeer-Sorten der örtlichen Brauerei in #Bonn-Pützchen. Gibt es in vielen Edekas im Stadtgebiet. Bin gespannt...

Das waren noch Zeiten, als man mit einem einzigen Desktop-Programm Anwendungen für Textbearbeitung/Editor, LaTeX/BibTeX, Entwicklungsumgebung/IDE für alle populären Programmiersprachen sowie ELISP, E-Mail, News/Usenet,
IRC, Terminal, Wörterbuch und mehr bedienen (und nach eigenen Wünschen frei anpassen) konnte.
Und zwar auf allen Plattformen (Linux, IRIX, Solaris, Windows, DOS...). Will heute praktisch niemand mehr...

In the early 2000s, a #CS student and myself developed an #IDMEF/#IDXP compliant security event message pipelining framework for collecting and consolidating messages from network #IDS, and #EDR products.
In the messages stream, we were able to match multi-stage #correlation #DetectionRules in near real-time (in-memory), before everything was stored in central database. Structural graph-based #AnomalyDetection was developed later by some colleagues.
We called it #MetaIDS.
In case you wonder how we programmed our stuff in #C++ on #SGI IRIX: We actually avoided #IRISPerformer after 1995.
For many applications, we used an #3DGraphicsFramework called #VTK on top of #GL and later #OpenGL.
When implementing #software in higher level #ProgrammingLanguages and #ApplicationFrameworks, it is always useful to understand the concepts under the hood. This book may be helpful, even when not programming in a #UNIX-like environment:
#Programming graphical applications for the #XWindowSystem under #SunOS, #Solaris (and #Linux, later) was a real pain in the a**, even when using the #XToolkit or even #XView.
Fortunately, I saved some literature from the trashbin to remind me of that ;-)
SGI IRIX Onyx was the most powerful 3D graphics hardware available in the first half of the 1990s. $~250k and occupied a small room on its own.
We had one at GMD-FIT for developing 3D augmented reality applications in C++, and occasionally we played Doom on it over LAN.
Approximately 5 years later, 3D PC graphics cards (such as the legendary FireGL for $~250) were at least as powerful as the Onyxes.
Falls jemand einen hervorragenden #Grafik-Designer aus #Bonn brauchen kann, #AlexWischblau ist als @awitzlau auf Instagram erreichbar.
So, nun auch mal was anderes hier. #Kunst aus #Bonn.
RT #AlexWischblau @awitzlau:
Fire on the hills.
Maybe.
