Online music school saves cash with Linux [ 12:54 Uhr ] [ 119 Worte ]

WorkshopLive.com is a virtual music school that features dozens of professional instructors teaching lessons online for all levels of expertise, in guitar, bass, keyboard, and drums. When WorkshopLive was in the early stages of development, the company had limited funds to devote to hardware, software, and human resources, so CTO Marilyn Hoefner decided to give open source software a try. "We've been extremely happy," Hoefner says.

The Challenge Of Requirements [ 21:44 Uhr ] [ 347 Worte ]

Genau das muss durch die Informatische Bildung Allgemeinwissen werden ;-)

Andriy Solovey gives 6 reasons why software requirements are elusive. A very interesting post which poses the challenges involved in identifying the requirements. The subjectivity, personal bias and preferences and continuous changes make it difficult to really complete the task.
I also feel that an inherent problem is that we start with the requirements and software instead of problems and solution. We need to look at using software for building solutions, which essentially means that we start looking at problems. Most of the times the customers bypass this step, for various reasons cited by Andriy. I believe the problems are directly tied to the Return On Investment (ROI) and value that the software will provide. More often than not the requirements end up being created to justify the use of software. Instead, the requirements should be a natural derivation from the problems identified.
Also, most of the times the customer and the software development team are on either sides of the table. They should not be. They should be together in this, providing insight and building software. The collaboration fails when the requirements are ignored or tweaked to fit the project management techniques.
I feel the irony in giving too much importance to software itself instead of the problem at hand. Which ends up ignoring a lot of things not inherent to the software domain, like processes and people. To be able to build a successful solution, software has to be treated as a part of the whole solution. The requirements have to represent the real world problem first and then translated into specifications.

Department of Education Resources [ 18:58 Uhr ] [ 236 Worte ]

Vorsicht! Ich habe bisher keine Zeit gefunden, das Folgende auch zu prüfen. Daher ist durchaus damit zu rechnen, dass die Materialien mit Informatischer Bildung nur wenig zu tun haben.

It is amazing what you can find when you troll the Internet for information on US Department of Education resources. Did you know that the US DOE keeps something called Federal Resources for Educational Excellence? Within that site there are links to useful content for teachers of all subjects (including computing).
The list of computing resources can be found
here I recommend the Computing link and also the Cyberethics link for elementary and middle school teachers.
If you are a computing teacher in your district share this page with all of your teachers (no matter what the subject) for the resources that are available to them. You can also talk with your science teachers about collaborating on a project that is highlighted by some of the science and technology links available from the computing page.
Enjoy!

Ped 2.17_final [ 23:56 Uhr ] [ 108 Worte ]

Ped 2.17_final - neue Fassung der beliebten Entwicklungsumgebung für Mobile Programming auf S60 3rd Edition

Ped 2.17_final veröffentlicht ;-)

Um die neue stabile Version Ped 2.17 zu nutzen, muss die entsprechende .sis-Datei von Ped 2.17_final heruntergeladen werden. Sie funktioniert nur, wenn Python auf dem Mobiltelefon installiert ist.

Auf der Webseite mit Hinweisen finden sich in der ersten Reihe Bildschirmfotos, die ich gemacht habe. Wenn Sie alle sehen wollen, finden Sie diese unter: Bilder zu Ped 2 auf dem Mobiltelefon

Ped 2.17_final enthält auch einen Verweis auf den Quellcode.

Interview von Stuart Feldman mit Alan Kay [ 22:04 Uhr ] [ 78 Worte ]

Neu ist es nicht - aber lesenswert

Bereits im Dezember 2004 wird ein Interview von Stuart Feldman mit Alan Kay in der acmqueue veröffentlicht. Ich fand ihn gestern durch Zufall.

Auch wenn Alan Kay sicherlich so langsam alt wird, sind seine Beiträge allein schon deshalb lesenswert, weil sie das berücksichtigen, was ich für unabdingbar halte: die Geschichte der [Didaktik der] Informatik.

Ich empfehle den Beitrag als lesenswert.
