Free Games

Check out the Web site of Jean-Baptiste Lamy, the co-inventor of the VCM medical glyphs, for free GPL games @ http://home.gna.org/oomadness/en/about_me___/index.html.

Links to the games are displayed at the top and on the left-hand side of the screen.

Road Signs for Physicians

French researchers have developed a new iconic drug information system inspired by road signs. This icon system is named VCM, short for 'Visualisation des Connaissances Médicales' in French, which means 'Visualization of Medical Knowledge.' See below:



Like road signs, the VCM graphical language uses a small set of graphical signs. The current dictionary contains about 130 pictograms displayed in 5 colors.

Sex Differences in the Brain

Sex Differences in the Brain: From Genes to Behavior (2007) by Jill Becker, Karen Berkley, Nori Geary, James Herman, and Elizabeth Young, from Oxford University Press, is an edited volume that in its 3 major sections; Strategies, Methods, and Background, delves into sex dimorphisms in an evolutionary context. This book requires a strong background in biology, endocrinology, and neuroscience but is worth reading even with a weak background in these areas.

Evan Balaban, writing in Science magazine (Science 21 March 2008:Vol. 319. no. 5870, pp. 1619 - 1620), concluded:

"All readers will learn something of value from this book, even if they don’t agree with the views of particular authors. Information content is high, references are ample, and the continuity between different chapters has been skillfully coordinated."

Nancy Yanes-Hoffman offers a detailed review at her blog and while she has some criticisms she also concludes:

"While scientists and researchers have long needed a book like SEX DIFFERENCES, its readership should not be limited to academia. The questing student of any age will find answers to many thorny questions—as well as more challenges to his or her perspectives and relationships".

She also suggests sources for further reading

Rules for Object Orientation

These constraints are intended to be excessively restrictive so as to force developers into object orientation:

1. Use only one level of indentation per method. If you need more than one level, you need to create a second method and call it from the first.

2. Don’t use the “else” keyword. Test for a condition with an if-statement and exit the routine if it’s not met. This prevents if-else chaining and every routine does just one thing.

3. Wrap all primitives and strings. This directly addresses “primitive obsession.” If you want to use an integer, you first have to create a class (even an inner class) to identify its true role.

4. Use only one dot per line. This step prevents you from reaching deeply into other objects to get at fields or methods and thereby conceptually breaking encapsulation.

5. Don’t abbreviate names. This constraint avoids the procedural verbosity that is created by certain forms of redundancy—if you have to type the full name of a method or variable, you’re likely to spend more time thinking about its name.

6. Keep entities small. This means no more than 50 lines per class and no more than 10 classes per package. The 50 lines per class constraint is crucial. Not only does it force concision and keep classes focused, but it also means most classes can fit on a single screen in any editor/IDE.

7. Don’t use any classes with more than two instance variables.

8. Use first-class collections. In other words, any class that contains a collection should contain no other member variables.

9. Don’t use setters, getters or properties. This is to enforce encapsulation as well as implementing dependency injection approaches and adherence to the maxim “tell, don’t ask.”

Free Prototyping Tool

Check out the free prototyping tool ProtoXaml @ http://www.codeplex.com/protoxaml.

You "sketch" a User Interface to gather feedback and ideas and turn it by a mouse click into an artifact that Designer and Developers can refine.

User IQ

Simon Guest has developed a tool he had to help decide what user interface platform was the best from among the more than 30 user interface technologies that Microsoft has

Simon's app, UXIQ, asks 12 questions which you answer on a sliding scale. Ultimately, you're given three recommendations to decide on. Both the app and source are available on Simon's blog post.


Where Is Microsoft Going?

To find the answer, read Microsoft Chief Software Architect Ray Ozzie's memo of October 2005 @ http://www.scripting.com/disruption/ozzie/TheInternetServicesDisruptio.htm

Google Patent

Please take a look at the Google patent application named "Transportation Routing". Its number is US20060149461, available @ http://www.arnoldit.com/lists/google-patents/pat20060149461.pdf

Note the drawing and what is being claimed, not just cars, buses, and trucks: in principle routing of satellites and spaceships. The transportation routing system was done casually. It's an example of how Google can innovate in some very surprising ways that can't be predicted

Google's approach to research and development relies more heavily on mathematicians rather than on software programmers with computer science backgrounds, although the latter still make important contributions to the search engine company's work.
