I finished UCSD in 2 1/2 years at age 19 with a degree in Molecular Biology. The following year I was attending grad school at SDSU in pathogenic bacteriology. I decided to do something different. I've spent thousands of dollars at bookstores. That netted an Extra Class ham license, First Class Radiotelephone license, a teaching credential, a pilot's license and extensive experience in electrical engineering and computer science. My colleagues today are people with PhD's in math. We create sophisticated digital signal processing equipment. I design the hardware (so that it is possible to write the firmware) and collaborate in the design of the signal processing algorithms in MATLAB. I then turn the MATLAB models into embedded firmware for the target device. I hand off my hardware designs to EEs to finish glue logic, board layout and fabrication. It pays better than genetic engineering and the lab smells better. Boiling pans of agar laced with beef heart infusion never really did much for me.
I try to avoid "new" releases. Vista is too green for me to deploy anything real on it. Still, I have to keep the skillset on the bleeding edge so my company is in a position to bid on future business that depends on the latest technologies. It's an endless rat race. Amazon and B&N make a fortune on my purchases. Still, it's worth every penny to maintain the edge.
DARPA is looking for people to build autonomous robots with 802.11g MIMO wireless and mesh networking to deploy in a combat scenario. The challenge is that the robots must meet at $100 each price point. I have a colleague that is doing the robotics piece. I'm doing the mesh networking and wireless. Chipping away at the costs will be the biggest challenge.

Wow, you can’t be a US citizen if you are that smart! (Just kidding.) As I was trying to tell Top Quark, the story of Robert Noyce (which sounds like your story) is also worth reading. It is found in the Tom Wolfe book “Hooking Up” in the essay “Two Young Men who Went West.” Both your story and Noyce’s are great examples!
I got two undergraduate degrees and never got a postgraduate degree, but for me, working at IBM and Apple on operating systems and device drivers was just as “educational.”
$100 each? In government dollars? Good luck with that. Even the micro UAVs are going for over $5K and they are just glorified RC models with a camera.
I redesigned the CPU scheduler for the UNISYS/7000 (Tahoe), fixed the MPCC drivers, X.25 and X.29 link layers and the async device drivers. Previous to that I had fixed up the segment swapper on the UNIX-1100 platform as well as fixing the interfaces to the GCS for async dialup users.
When I moved to my current employer, I was drafted to port the Mentat SYSVr4 STREAMS into the HPUX-7 kernel on the 68040. Mentat provided the original source to the OSF. I also created a tunnel driver between the BSD and STREAMS stacks to allow native applications to pass onto the new STREAMS stack. I back-ported the HPUX-9.0 multi-LUN SCSI driver to work on the HPUX-7 kernel to permit installing the Spider DLPI (mapping X.25 to IP), X.29 and X.25 drivers and ultimately a proprietary device driver for the military to interface to a GE X.25 switch. That was a 6 week marathon effort. Lots of fun, but very tedious to single step the kernel through the device driver code. I had a particularly interesting conflict between the Mentat scheduler and what Spider expected in a STREAMS scheduler. Tracking that down was a 1600 step process to identify an order of execution problem and modify it to be fully re-entrant. Running kdb on a kernel is primitive.
My DSP work today is focused on special compression techniques. The railroad contract includes DSP aimed at vibration signature analysis on railcar bearings. The key objective on the railroad task is to drive all the electronics down to board level custom embedded systems that are dirt cheap and rugged enough to handle the pounding that comes with the rail environment. The vertical accelerometers are rated +/- 80g @ 50 KHz. I'm going to try to save money by sampling 2 channels with a stereo DAC connected with the SPI bus to a TI DSP chip. That approach will be much cheaper than the current Diamond Systems DMM32 at $750 a pop. The DSP chip will do the FFT of the samples far more efficiently than the general purpose PII on the CPU board. Cheaper too.
Don't fret about missing the postgraduate degree. Every green college grad has to learn the ropes at a given employer. Everyone has a different focus and set of expectations. It is important to keep your skill set current so you are marketable as the next big processing fad comes by. AJAX and SOA are hot buttons right now. They useful arrows in the quiver, but my customers are paying for quality DSP ahead of flashy "pop" technology right now.
I have the SmartCharger element of the railcar optimized down to 1.9 mA of current draw attributable to running the microcontroller. I'm pushing to see if we can switch the fast 4 MHz oscillator off and keep the controller relatively idle on a 32 KHz watch crystal. The would be a big power saver. I'm waiting for feedback from my hardware fab house to see how that compares to the actual power requirements of the 4 MHz oscillator before burning labor hours to further "gold plate" the current consumption aspects of the device.
Good posts!
It’s great that there are highly capable Americans capable of filling the kinds of jobs Gates is talking about.
But anyone familiar with the situation of most American grad schools knows that the engineering and computer science programs in said schools are disproportionately filled by foreigners.
That’s a fact, and facts aren’t anti or pro American-— they just ARE.
To train people from other nations in skills that could add to our domestic economy, yet then keep them from doing so is dumb.
You are welcome
You come here every few years to post a bit.
As far as what you posted about the American people I have a great idea. Keep it to yourself and your friends and don't put it out here
So you teach a lot of foreign IT students who want to stay here long term after graduation, maybe become Americans
Aren't they being pushed aside by H1-Bs who will work for less? And if not pushed aside immediately then 5-10 years after graduation
So an Indian fellow studies IT here but gets lousy pay, can't pay his student loans after graduation because tons more Indians are coming in on H1B visas
Well, the only way the foreign student can stay as you describe is through..........H1B
So an Indian fellow who studies four years at MIT can only get an IT job with an H1B visa? I find that hard to believe
I suspect this is a toy for his liberal wife to play with : )
No way. Gates believes in this 100%. Same for Warren Buffet who has pledged to kick in billions to the Bill and Melinda Gates Foundation over some years. His name is on the foundation and I'll bet he discussed his legacy/foundation with wife before they got married
I know about IT because I work in the field. There may be other abuses. I do know that Mirant fired their accounting staff and hired Indian workers. This happened while Mirant was in bankruptcy. Also, the top brass voted themselves raises, had special lunches, expensive bottled water and all kinds of perks during this time while their stockholders were taken to the cleaners.
There have always been students who remainined in this country legally-before H1B visas even existed. This program is not needed except for very rare cases where a certain expertise is needed. I think I’ve seen one or two case like that in my entire working life.
Most of the Indian students I knew had no student loans. They were subsidized by their families or by their government.
So, this is why Bill Gates is no longer the richest person in the world and now a Mexican man is?
I saw it happen at Sprint and Mirant-American workers pushed out by H1B visa holders who were not even supposed to be hired unless there were no Americans capable of doing the job. It’s not just about cheap labour. These companies have an anti-American bias. America is somehow inferior in the eyes of these free traders.
