|How I became a computer programmer.|
This autobiographical article was first published in Windows Tech Journal, as a way of introducing my WinWidgets column to the readers. It provides a punch line to the old joke, "Six years ago I couldn't even spell 'programmer'…now I are one!"
I suppose I was destined to come to no good end. When I graduated from high school in 1969, everyone knew you needed a college degree to make a decent living. But I dropped out of college not long after starting it, needing to support a wife and growing collection of babies. So I worked at this and that—everything, actually, from running a pest control route, to singing professionally, working as a radio disc jockey, a sailor, and, finally, around 1978, as a fire control dispatcher for the Florida State Division of Forestry.
That means, each day it wasnít actually raining, I had to climb a 100-foot fire tower and stare at the horizon, looking for smoke. If I saw any, I had to radio another tower to triangulate the fireís location and send rangers to it to put it out.
Right away, it was obvious I didnít fit in. On rainy days, I would sit in the office and while away the hours laboriously typing a novel on an old Underwood. One day I was told by my supervisor that I had to stop writing while on the job.
"Why?" I asked. "I only do it when thereís nothing else for me to do."
"It makes the rangers uncomfortable," my supervisor replied. "They donít understand why anyone would want to write a novel."
I suspect it was the supervisor who was uncomfortable, not the rangers. Either way, rescue was at hand. One day they delivered a big, bulky teletype and set it on the floor in the radio room. We three dispatchers were informed that, once each day, we would check our instruments, record the dayís weather, encode it, and use the teletype to transmit the information to a waiting computer in Seattle. In return, the computer would calculate the likelihood and intensity of fires for the afternoon; we could use that information to gauge how many rangers to send to a fire and, for that matter, how many could take the afternoon off.
The other two dispatchers were aghast. One had been a computer programmer in the 50s, when that meant 15-hour days spent plugging thousands of little wires into teenier holes. He had burnt himself out—actually had a nervous breakdown—and ran, screaming, into the one career he thought would be safe from computers. And now, here one was. He calmly informed the supervisor that he would never touch the teletype, and they might as well plan on the other dispatcher and myself doing it.
That was okay by me; but the other dispatcher turned out to have a problem of his own. His name was Ralph, and he was a retired Army sergeant. Well—the Army no longer paid him; but he took the Army attitude with him wherever he went. He had made himself General of the office, spending his days designing unneeded forms and chewing out the rest of us when we refused to use them.
Anyway, I discovered Ralphís problem the first day he tried to enter the encoded weather. He had been at it for about 20 minutes—a job that took me less than three—and I looked at the printout to see what was the matter. It turned out that Ralph was entering the letter "L" instead of the digit "1". I pointed this out to him.
"Iíve been using typewriters since before you were born," he snarled, chewing on his ever-present cigar, "and I have always typed a ĎLí for Ď1í."
"The computer expects a Ď1í," I shrugged.
"The computer will have to change, then," he snorted, "because Iím not going to." He was still typing the same erroneous line an hour later when his shift ended; and I was the one who transmitted the weather correctly afterwards.
As for me, I had never suspected I might have a talent for computers because, at that time, everyone knew you had to be "good with numbers" to work with computers and I could barely remember a phone number long enough to dial it. Still, I memorized the manual that came with the teletype and discovered the paper tape recorder/reader. Using it, I wrote macros for the system that got my connect time down to under one minute…something that caught the attention of the Florida State head programmer, who came to visit. He wanted to find out why our connect charges were so low. "They think youíre cheating the system somehow," my supervisor said. "If they find out how youíre doing it, theyíll probably have you arrested." But the programmer knew I was getting the weather every day. He just wanted to find out how. I explained the macros to him, and soon a memo went to all the districts recommending they use my technique.
My supervisor was visibly upset. I had brought attention from the state itself, and he didnít know what to do. All he knew was that I was obviously trouble and needed to be put in my place, somehow, soon.
But I didnít care. I had a couple of yearsí VA college benefits coming to me from my stint in the Navy; I had been saving them for when I had some idea what to study. Now I knew. I quit the Division of Forestry and signed up for the next term at the University of Florida at Pensacola.
While there, I discovered an old PDP-16 and found it irresistible, even though my classes were in mainframe languages COBOL and FORTRAN. One night the head of the Systems Science department found me working on the thing at two in the morning. I didnít even know who he was. We chatted about my project, which was a program that would convert BASIC code into COBOL. He was impressed, told me that was "systems programming," and suggested Iíd be right for a certain co-operative education position in Washington, DC. A month later found me in that position, coding PL/I and Assembler for the EPA.
It was a six month position, and man, did I learn a lot, from a group of folks who were among the best programmers (and finest people) Iíve ever met. In addition to bringing me up to speed on PL/I (which I hadnít yet studied), they taught me a lot about the ethics of programming and even more about being comfortable with being myself. Each of them was eccentric in his or her own way; but, instead of letting their eccentricities embarrass them, they reveled in them.
And they loved the fact that I wanted to write, and read and critiqued anything I brought them, in their spare time.
Then I found myself back in school for another six months. It was a strange time; because I had already learned at the EPA just about everything my classes had to teach me—and more thoroughly. Finally I just took my remaining classes by examination. Now, the only thing left between me and my degree in Systems Science were two courses in Accounting, one in Statistics, and one in Calculus.
I made the mistake of asking the Calculus teacher what I even needed Calculus for. He became livid, leaping to his feet in maniacal rage. "YOU USE CALCULUS IN EVERYTHING YOU DO!" he screamed. "EVERYTIME YOU CROSS A BRIDGE—EVERY TIME YOU ENTER A BUILDING—EVERY TIME YOU DRIVE A CAR!" I became frightened that he would actually have a heart attack—I had never known what "apoplexy" was before, but I was sure I had just witnessed it. And I still didnít know why I needed Calculus.
Back at the EPA for my second stint, I met a guy who had a small consulting business. He hired me to work part time for him. "Let me know if you want to take a contract from me for $20,000 a year," he said. "Once you make $20 grand a year, no one will ever offer you less." Everyone knew that you canít have security as a consultant, but $20,000 a year happened to be more than the head of the Systems Science department at school made. Suddenly, I decided that I didnít need Calculus, and with $20 grand a year I could pay an accountant. I dropped out of school—for the second time—and have never looked back.
My friend was right. No one ever did offer me less; and, through the years, I found my salary steadily increasing. An early job was with GTE Telenet; I was one of six people who designed Telemail, one of the first electronic mail systems. That job introduced me to Tandem minicomputers and I happily said goodbye to mainframes forever.
It was on the Tandem that I discovered object-oriented programming, though I didnít know it at the time. There were several library functions in the system that made use of structures they called "control blocks". A function would initialize a control block, and others were passed the structure as an first parameter. Although it was possible to look at the structure, there was no need to; the data and related functions were neatly encapsulated and I thought this was a really cool idea. I wrote a series of enhanced functions (simulating inheritance, I now realize) and created other objects ranging from trivial to a full-blown report writer. Thanks to my love of writing, I actually documented my functions (other programmers just stared at me uncomprehendingly) and so was able to actually reuse them. I quickly gained a reputation as an incredibly fast programmer; but, in truth, I didnít code any faster than anyone else. I just didnít code as much.
When PCs came out, I bought one. For awhile I had PCs and Tandems talking to each other. I was unimpressed with Windows 1.0, but 2.03 blew me away. I bought Petzoldís book Programming Windows and learned, not only Windows programming from it, but C as well! From then until today, I have coded for Windows exclusively, though I now use Visual Basic and C++ rather than C.
I sold my first article to PC Techniques and eventually wrote four books on Windows programming for that magazineís publisher, The Coriolis Group. The last one led to my being asked to write for Windows Tech Journal and that led to my being made Contributing Editor to the technical newsletter then called VBX/OCX Journal, later called Component Builder.
Do I ever regret not getting my degree?
Not for a minute. I know some terrific programmers with degrees. But I know more bad programmers with degrees than I know good ones. Apprenticeship and experience, in my opinion, are far more valuable than memorizing algorithms assigned by an instructor who has never needed to use them outside of academia. As a consultant, I was paid large sums of money to get stalled programming projects on track. In every case, the project had stalled because some over-educated geek kept adding "layers" to a complex project, trying to simplify it, until the thing was completely unmanageable. Only real-world experience can tell when additional layers will obfuscate rather than clarify…and, in my opinion, you can only get that experience on the job.
So I have come to no good. I am the man that mothers shield their children from: a professional who doesnít recommend Higher Learning. (I do recommend junior college, for the general education.) What can I say? I got involved in computers when everyone knew you had to have a math aptitude I lacked. I left mainframes at a time when everyone knew they were the answer to a secure future. I left Tandems at a time when everyone knew minicomputers were taking over the industry, and starting coding Windows when everyone knew graphical user interfaces were "just a gimmick."
It seems that what "everyone knows" turns out to be wrong more often than not. My advice: if you want to be right, listen to your heart. And the voice of the heart comes from experience, not a university degree…or from what "everyone knows".
