example graphs

 Will this company be successful and become another Google?
 First, graphical data mining has never been a big hit. And second,
 there are lots of competitors in the business intelligence sector,
 including at least Business Objects, Cognos, Hyperion and MicroStrategy.
 So make your bets and wait for the next multibillion-dollar IPO.

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.

Knowledge Management from personal content management tools   25 Sep 04
[print link all ]
I shamelessly copy this blog-entry from here
 Below is a quote from Dave Pollard, the former Chief Knowledge Officer from
 Ernst & Young. It is a great paragraph because is is truly representive of
 why enterprise knowledge managment solutions failed. He is talking about the
 fact that knowledge managment systems have to be personal content management systems first.

 Quote:

 I believe personal content management tools are the place to start, because
 since the earliest days of business, the principal way of sharing information
 has been peer-to-peer, the most valued 'repositories' of business information
 have been personal filing cabinets, and the principal schema for organizing
 work has been the personal desktop. It makes sense, therefore, that tools
 that facilitate and reflect these well-established 'knowledge processes',
 information sources and networks should be much more successful than the complex,
 centralized, hierarchical knowledge management tools and repositories that have
 been foisted on users for the past decade.

 End Quote:

 It is a great quote because how is it possible that anyone could believe that
 a centralied hierarchical tool could work when it was in no way related to how
 people did and have done knowledge work since the beginning.

Del.icio.us and Bit Torrent: Google in Reverse   25 Sep 04
[print link all ]
why has put that interesting posting on his blog
 Inside my head, I sometimes refer to Del.icio.us as the Google In Reverse.
 Google has amassed a solid mound of ranked and twined web sites. The
 standings shift about with caution, the behemoths are tough to dethrone.
 And if I ask for Ruby, the answers in place may hold through the end of
 the year.
 ...
 Del.icio.us is perfect! The activity bred by competitive linking would
 be enhanced by the sharing of richer media.
 ...
 Better client software is needed to make this happen.

A big thanks to Leftenant Berezka for the pics :-).

Been coding hard now on SW and CFaR. I would really need some good vodka now before getting up early tomorrow morning to catch the train.

Hope you all had a good weekend, -A.

This vodka bottle reminds me that I am way behind on Futurometer. We will kick ass there soonish!

Wine-Migration   25 Sep 04
[print link all ]
At Linuxtag in Karlsruhe I met during lunch one of the authors of ganymede. I am the last person in the world to promote the use of the Win32-API, but it can come in handy, when you have to use some legacy software on Linux and do not want to pay license fees for the usual suspects like vmware. Having to maintain only one code-base is sexy, too.

I asked David Guembel, one of the fathers of the software to email me a short describtion:

 On an abstract level, the idea behind our ganymede system is simple: To make
 an application run under Wine (a free Win32-API layer and Windows
 executable loader), it is neccessary to know what parts of the Windows API
 are actually required by that particular piece of software. Software has a
 modular structure - in this context, a module is a Windows executable
 (.DLL, .EXE, .OCX etc.) - and every module provides (exports) certain
 functionality and requires (imports) functionality from other modules.
 Thus, ganymede internally creates a dependency graph of an application's
 binaries. This method is static and does not require anything but a fresh
 installation of the software to be analyzed.

 Before x-raying a Windows application, ganymede parses and stores an
 analysis of the soure code of one or more Wine versions. It automagically
 determines the implementation state of the APIs provided by Wine. During a
 software analysis, the functionality required by the Windows application is
 compared to what Wine provides, and missing or incomplete APIs are
 reported. By storing Wine versions and the dependency structure of the
 analyzed applications in a database, automatic or manual re-analysis with
 different Wine versions is possible. Via the API ganymede itself provides,
 the collected data is accessible in several ways. One application of that
 API is our tool named sysiphus, which uses ganymede and a GUI-based
 approach to semi-automatically determine the best possible Wine
 configuration while providing for the possibility to re-use already
 licensed Windows DLLs to fill the gaps Wine still leaves.

Software for Slackers   25 Sep 04
[print link all ]
I need this program to stop my internet addiction.

Are you a slacker? So am I. Do you browse the Web, read the news, and write email all day in stead of working? So do I. Does it make you feel miserable and apathetic? Do you tell yourself to stop browsing the fucking Web and get some bloody work done? Do you have absolutely no discipline? I know your pain.

But recent technological advancements have made it possible… There is a cure for your disease!

Years of slacking at the renowned Massachusetts Institute of Technology have resulted in a brilliant 461-line Perl script (which includes 130 lines of comments for free!) that makes it all possible! Your productivity will dramatically increase!

Today, I present Lockout: The Self-imposed, Computer-aided Work Enforcer. This program will help you get some work done by not allowing you to browse the Web. It won’t allow you to do anything but work. It’s a miracle! Your colleagues will respect you, your Ph.D. adviser will compliment you, and your boss, if you have one, will probably not notice the difference! It’s amazing! Scroll down! Read more!

The Linux Incompatability List   25 Sep 04

Saw this on /.

"The Linux Incompatibility list is a wiki project that attempts to document hardware that is incompatible with Linux rather than list what is compatible. In the wiki, it is possible to add alternitives so as to push hardware manufacturers to make good binary drivers, publish specifications, or even better, publish open drivers."

Forth Database   25 Sep 04
[print link all ]
Richard S. Westmoreland postd this to the Forth-ML.
 In years past, we have implemented some extremely complicated databases in
 Forth.  The first was done in the mid 1970's for the company Cybek in NJ,
 and it was used in some extremely complex applications.  FORTH, Inc. also
 did some very complex databases for other companies, one of which was still
 in use last time I checked, at www.calmuni.com.  That one was a
 2-dimensional database, with a huge bit matrix in the center used to
 calculate overlapping bonded indebtedness.  A few years ago my contact  there
 told me that a state agency had just spent several million $$ trying to
 replicate it using modern database tools, but the result was too large and
 too slow to be usable.

 In the late 1980's we added class-based techniques to it, which many people
 liked (although I personally preferred the earlier, simpler version).

 It's hard to describe the whole approach in a newsgroup post, though.  It
 certainly didn't resemble SQL!

Forth "versus" Whatever   25 Sep 04
[print link all ]
From comp.lang.forth
 >>Which brings me to an excellent 'forthism' I once read in a
 >> newsletter.  It stated:
 >>
 >>     "You can do anything in Forth - but you must be prepared
 >>     to do it yourself."
 In a recent discussion in c.l.functional, about why popular languages
 are popular, I summarized the relationship between Lisp and Forth
 more-or-less as follows:
 "From the Lisper's perspective, every other language is a cute subset
 of lisp; whereas from the Forther's perspective, every other language
 is a cute extension of Forth."
