| FREERTOS FRENZY/ BARR'S NASTY BUGS/ GANSSLE IS (TEST-)DRIVEN | |||||||||||||||||||||||||||||
| I count myself lucky each week if I come across just one news ordesign article captures my attention. This week, though, I found atleast half a dozen Embedded.com articles that are compelling reads.
First, there is Jack Ganssle's “Interview with James Grenning“,a signer and supporter of the Agile Manifesto, about the controversysurrounding “test-driven development” and its suitability for embeddedsystems. Complementing Ganssle's column is my Editor's Top Pick: “How to use new unit testing tools andtechniques to improve software quality,” by Mark Pitchford.If you are tempted to dismiss the need for such disciplined softwaredevelopment methodologies, read Michal Barr's latest column on “Five top causes of nasty embedded softwarebugs.” Another compelling read is “Buy or roll your own? Neither with FreeRTOS,”by Richard Barry, director of Real Time Engineers Ltd. According toRich Nass in “The resultsfor 2010 are in,” our survey of 1,500 developers showed thatFreeRTOS was their first choice, not only ahead of Linux, but also anyof the commercial RTOSes. And because I am still puzzling over what classes to attend at ESC Silicon Valley (coming uplater this month), “Multicore technology training for embeddedsystems designers” by Multicore Expo's Markus Levywas enormously useful in sorting through my choices. Finally, there are the two features from this month's ESD Magazine: “Developing aflexible firmware architecture ,” and “Expressive vs.permissive languages: Is that the question? “ Both made mequestion my assumptions about programming – my ultimate test of anarticle's value. Good reading! (Embedded.comEditor Bernard Cole, bccole@acm.org ) BREAK POINT by Jack Ganssle |
