XP success story: Sabre takes extreme measures   25 Sep 04
[print link all ]
(Source: Computerworld) Using extreme programming practices, Sabre Airline Solutions has reduced bugs and development times for its software products.

Sabre Airline Solutions had many years of experience with its AirFlite Profit Manager, a big modeling and forecasting package that many airlines use to wring more income out of flight schedules. Even so, Release 8 of the software was four months late in 2000 after final system testing turned up 300 bugs. The first customer found 26 more bugs in the first three days of its acceptance testing, and subsequent joint testing by Sabre and the customer uncovered an additional 200 defects.,10801,91646,00.html

This tiny tool is great to have 2 people look and type into the same shell window. Works great with vim :-)
  • Both ssh or telnet into the same (remote) Unix machine and account.
  • One enters screen, then starts vim, then the other enters screen -x.
  • ctrl-d to exit screen)

I just now came across the rubyx website and noticed the logo. Nice!

Rubyx is a Linux-distribution similar to Gentoo, but all based on one ruby script :-).

(Source: Kent Beck posted this to the XP mailinglist) This came up in a discussion of how to handle long-lead-time materials. The OP basically said,
 "I can't do all that stuff you say I should do, but how do I handle the situation ..."
  The response:
  -- IT WON'T WORK HERE doesn't work here.

Agile Processes Summarized   25 Sep 04

(Source: Ron Jeffries and Alistair Cockburn, XP-ML)

I think that to get a group to be agile, you have to get people to do something like one of these things:

  1. Go in that room there and do all 12 XP practices until you actually do know better. (XP)
  2. Go in that room there, don’t let anyone screw with you, work on whatever you think you can get done for a month. Keep doing that until everyone is happy. (Scrum)
  3. Go in that room there, in peace love and understanding, ship software every month (*), and think about it. (Crystal Clear.)

There is a telling sameness to all of these, is there not? —> This is a wonderful summary of a summary! There’s not much to be removed (see Saint-Exupery, below). In Italian, the expresso of an espresso is called a "ristretto" (any Italians online?). This is the agile ristretto. It belongs on a Blog or something. "La perfection est atteinte non quand il ne reste rien a ajouter, mais quand il ne reste rien a enlever." (Saint-Exupery)

[print link all ]
DataVision 0.8.2 is now available from SourceForge at

DataVision is an Open Source reporting tool similar to Crystal Reports. Reports can be designed using a drag-and-drop GUI. They may be run, viewed, and printed from the application or exported as HTML, XML, PDF, LaTeX2e, DocBook, or tab- or comma-delimited text files. The output files produced by LaTeX2e and DocBook can in turn be used to produce PDF, text, HTML, PostScript, and more.

DataVision is written in Java and uses JRuby to add Ruby scripting.

Visualising wikis   25 Sep 04
[print link all ]
been surfing to get good ideas about visualising knowledge.

The pics shows "history flow" from IBM research. Tons of other good links can be found in the c2-wiki.

Visualising is really interesting and up for a major change. I am totally sick of all these boring search-engines out there and yeah, grep -r is still my best friend. Another reason why I despise MS-Word, he, he and use LaTeX. It took me years to fall in love with that programming-language, which happens to be a word-processor, too.

Executive Dashboard   25 Sep 04
[print link all ]
Thanks to Sven C. Koehler. He pointed out me to Edward Tufte’s interesting forum. There are some interesting answeres in the thread, esp. the graphic about the patient. Isn’t every company a patient? :-)
 I'm developing an executive dashboard, and I haven't been satisfied
 with the business graphics that are widely available
 (e.g. gauges, dials, stoplights). I decided to make a "Zen" version
 of a KPI status indicator, using as little color as possible,
 and incorporating E.T's innovative "Spark Line" metaphor for display
 of trends. The graphic below shows the proposed KPI display across
 the top of a browser screen with a descriptive example in the middle.
 Any feedback would be wonderful!

 Comments: Because of complex KPI names (e.g. This Week versus Last Week
 Sales (All Divisions), KPIs were labeled with Roman numerals.
 Balloon help could display the KPI name when the cursor brushes the
 KPI indicator.
