I started with computers when I was 14 and became a computer professional at age 17 when I wrote a real-time multi-tasking operating system for ship, pipeline and refinery control while attending Tulane University in New Orleans.

From there, at 19 I passed on jobs at Apple and Microsoft (in '83) to join Digital Equipment Corporation where I helped found two support businesses for them.

I then joined Relational Technology Inc. (later Ingres Corp), and, as a direct report to the Sr. VP of Sales, performed just about every technical role in the company, curriculum development, consulting, technical support, development, benchmarking, created Demos, represented the company at trade shows, etc, and I even helped sell the product.

After a while as an independent consultant, Professor Michael Stonebraker invited me to lead a research team at UC Berkeley's Electronics Research Laboratory wherein I developed the world's first "Grid" computing system - which was also the first truly heterogeneous distributed computing system, today known as "cloud computing."

In '97 I commercialized the work and founded several companies where today I have a split life as "executive" and technical wizard - in short, I serve as chief cook and bottle washer. I'm a jack of trades, and specialize in computing performance and heterogeneity with an eye toward production work, stability, maintainability and up-time performance.

In the last few years I have become involved with life-sciences computing, and last year served as CTO / VP Engineering of a company bringing health-information to the masses, but unfortunately that venture folded due to what I will politely call, "capitalization issues."

comment SETUID / SETGID on a binary executable stopped working following upgrade of Fedora Core
@MIfe I've been trying but there seems to be a bug; NOTHING happens. I either look at your link and it's blank, or I try the "automatically move this discussion to chat " and I see things but NO chance to type anything. It says I should log in to chat at the bottom BUT I AM LOGGED IN, clearly!

added the code in the C program that's having the error. Then added 'ls -l' output.

@MIfe Note the code that's running is now in the question section above. At first I said maybe it was the part that was calling Java, but no, it has trouble before that and I cited the code...

@MIfe Of course. It runs perfectly as the developer which is why I never noticed the problem over this long period of time!

@MIfe Sorry, I thought "program" was enough to make it clear it's NOT a script. It's actually a C program. I'm not sure just what the file access error would be, but it refuses the reads. Your guess about NFS was good: yes, NFS. ...The application was first written in 1997 or thereabouts and has worked all this time under the exact same scenario - the only thing that has changed is the OS version, even the build scripts and NFS mounting are the same!

comment FC19 FirewallD debugging help requested: ports not forwarding
@MichaelHampton OK, you're right; it was a too-easy assumption. Frankly, I don't think a down-vote should be permitted without a comment on WHY. In this case, I suspect this answer got downvoted three times because it reflects that I finally realized you were right - Fedora Core isn't ready for Prime Time, "production use", at least not THIS version of it. And people don't like facing the reality that their favorite whatever actually deserves criticism. BTW, FWIW, I like FirewallD / Firewall-cmd, they're just not ready yet.

@MichaelHampton Thanks for the down-vote - it's obvious my comment pertains to the network issues related to firewalld, but you want to voice your snit. fine.
