- About The Embedded Muse
Last issue I referred to a set of RAM testing guidelines. Michael Barr, Embedded Systems Programming’s Editor-In-Chief, has an excellent application note about this that includes working C code. It needs but a single minor typedef change to work for 8, 16 or 32 bit wide chips. Check it out at http://www.netrino.com/Articles/MemoryTesting. Highly recommended.
I'll present my Better Firmware Faster seminar in Melbourne and Perth, Australia February 20 and 26th. All are invited. More info here. The early registration discount ends January 20.
Reading all of the recent press hoopla about .13 micron and now 90 nanometer geometries it’s easy to forget that a lot of the market runs very happily on much lower-end processes. Microchip’s PIC line is still largely .7 micron. 90 nanometer sounds awfully impressive, but life on the bleeding edge is always a trail of tears.
Finally, I wrote an article about Toxic Bosses (http://embedded.com/story/OEG20021031S0037). The accompanying poll was quite instructive. As of this writing, 72% of the 425 respondents are bound to their jobs by fear, money or lack of options. Few expressed delight in their work. That confirms my theory that when the economy improves, when more jobs appear, employers should expect a great migration of their embedded folks. This can’t be good for the bottom line.
I’ll be presenting my Better Firmware Faster seminar in Irvine, CA on December 4 and Dallas, TX on December 6. See http://www.ganssle.com/classes.htm for more information. This is the only non-vendor class around that shows practical, hard-hitting ways to get your products out much faster with fewer bugs. The crummy economy is putting pressure on all developers; come and learn the tricks you need to be more efficient.
I often do this seminar on-site, for companies with ten or more embedded folks who’d like to learn more efficient ways to build firmware. See http://www.ganssle.com/onsite.htm.
Thought for the Week
Here’s a great site: http://www.intuitor.com/moviephysics/. It’s a review of the physics in many movies. The writing is fun, and they take Hollywood to task for making a mush of physics. I especially like this quote about Titanic:
“We got a bit giddy over the high-tech submarines used in the opening scenes. However, we could have done without the hackneyed portrayal of the sub's technonerd staff. Had they merely been portrayed as crude, insensitive, and slovenly, we would have remained silent, but they were also portrayed as greedy money grubbers.”
“While technonerds may not be in the same category as Mother Teresa, Emily Post, or Little Mary Sunshine, we would like to point out that given the choice between living in luxury and driving high-tech mini-subs around the ocean bottom, real technonerds will choose the latter. It's a no-brainer. The only point of money for technonerds is that a certain amount of it is needed to support their techno-habits. Unfortunately, Titanic failed the reality test in this area.”
