The other day I was downloading an IDE for a new (to me) OS. When I went to compile some sample code, it failed. I went onto a forum, where I was told "if you read the release notes you'd know that the peripheral libraries are in a legacy download". Well damn! Looking back at my previous versions I realized I must have done that and forgotten about it. Everything changes, and keeping up with it takes time and effort.
When I first started with microprocessors we had ROMs which had BASIC and the ability to read a cassette tape. Then came the floppy disk and a new set of ROMs. When UV erasable PROMs came out it was awesome. Having the ability to turn around a code test in 20 minutes really sped up the process and allowed a lot more capability in an embedded system.
Today we complain if it takes longer than 30 seconds to program a 2 Meg flash based processor. The more ideas we can try in an hour, the sooner we can get a great product on the market. I think it is worth a few minutes every week to think about where you are, how you got there and where you are going. What you do today is going to be ancient history pretty soon.
Some of you went to work today riding on a train that went over bridges built by Romans over 2000 years ago. A tremendous amount of effort and expense went into building those bridges precisely because they were expected to last forever. While slaves may have built the bridges, engineers designed them. At the time there was no thought their work would be obsolete because technology just did not change that fast.
Today's bridges are bigger, longer and carry far more weight than anything the Romans could have imagined. But they need to be replaced every 75 to 100 years simply because iron is not stone. This is not a bad thing - as we learn more about quantum mechanics we learn how materials behave at the atomic level and we create new materials - lighter, stronger and more flexible than ever before.
The concept of meta-materials for electromagnetic fields has gone from laboratory curiosities to real applications. Why not think of meta-materials for clothing or mechanical structure? We need something better than we know about today to build a space elevator. The joke about quantum mechanics being people who work with atoms won't be funny any more. It will just be engineering.
I have a kid who wants to be a neuroengineer. Five years ago that did not even exist as a profession. Connecting computers directly to the brain is no longer science fiction. Do I really want an autonomous car or do I want absolute control with the ability to "feel" every sensor? I'm not sure yet - but I'm sure I'll have the choice.
Unfortunately there are some things which don't change but should. Take the percentage of women in engineering. For the last 20 years it has gone from 8% to 11%. The world has a lot of problems. It needs a lot more engineers. Males and females think differently and it has enabled the species to survive for millions of years. If we are going to feed some 9 billion people, keep them healthy and ensure decent living standards we need 50% of engineers to be women.
I've quit several jobs because I felt the people I worked for did not treat me respectfully. Twice as many women graduate with engineering degrees as there women in engineering jobs. Simply because they are not respected. This attitude has to become ancient history.
Take a few minutes and think not just about what you do, but how you do it. You are changing the way the world works, that's your job. And the way we do our jobs is changing too, as I found out the hard way. Changing technology is easy. Changing society is hard. The reason it is hard is because we have to change ourselves.

Dealing With Fixed Point Fractions
Your son enters a new scientific field but his way of thinking, his way of learning remains the same. After 31 years of teaching in classrooms for adults and spelling on my lips the principles of Malcolm Knowles nothing new is found. Peoples spirite ,many years after Knowles remains unchanged, nothing seems to follow a positive way.
Instead , we have something negative! Our century offers many negative ideas and the teachers give a fight to enter to the spirite of the students the truth !
Crossing the boundary from child learning to adult learning happens in college for sure. If you aren't self directed, you can't do well.
We hear in TV about microchips enrolled in the human body. I have here some programable eeproms having the size of the head of a match.
No leads are presented. Not a programmer is needed. You can program them sending radio waves. You can read them back by radio waves.Nice business following a negative idea with the absense of humanity. Everybody will be a microchip.
And more negative ideas applied. A monster car following the brain of a man and the monster brain of a man following the brain of another man.
Negative ideas, but business.
The term negative idea means :
1. An idea that is completely false.
The weight of a glass of coca-cola is increased when the gas of carbon dioxide is gone out because the gas is lighter than the water.
A physicist gave to me this answer during a seminar for teachers!
2. Ideas that are true but they have ,when applied, negative results somewhere, for example to the society.
Business that wants to stay around for a long time has to deal with truth. Fly by night operations don't. I'd say the damping function on negative ideas is pretty high. Definitely no fun to deal with while they are around.
