- Why did you choose to earn a degree in computer science? Was this a field you were always interested in?
My parents bought me an IBM PCjr when I was about 10 years old, around 1986. We were growing up in a small, rural farming town in southern Wisconsin. This was an incredibly insightful purchase -- a large investment in both mine and my younger sibling's futures. My mom stayed at home with us and my father was probably making less than $20,000 per year, and yet they decided to spend $1,500 on a personal computer. Neither my dad or mom ever touched it; somehow, they had the understanding that computers and computer programming were going to be powerful assets for their kids.
My mom bought me a monthly newsletter subscription to a service that would send BASIC programs to be coded in the postal mail. We'd code the game and then play it; I remember hangman being a particularly fun one that we coded multiple times. We didn't have any hard disk or any way to store the games, so whenever we eventually lost power or had to turn it off, we'd lose the program and have to write it again next time we wanted to play it.
It was a pretty obvious move for me to seek my computer science degree from the University of Wisconsin. [I'm] still trying to be half as good a parent as mine were.
- What are some of the most crucial skills you gained in your studies that apply to your job on a day-to-day basis?
I vividly remember those early days of C and Java programming. C in particular was frustrating, as programs would just kind of explode and trying to figure out where the bug was could be incredibly difficult, especially if that bug was in memory management. I remember many times thinking to myself that this compiler was broken or the computer itself must have some hardware problem if my program keeps exploding, because obviously my program was perfect.
The best class I ever took at UW-Madison was a class in compilers. In that class, we defined a new programming language from scratch. We wrote all the language processing and had to make a compiler from scratch as well, including all the error handling and error messages. We learned about lexical and semantic analysis, op-codes, and stacks, and it was both incredibly frustrating and incredibly rewarding when it was finished.
The reason it was the best class I ever had was I left understanding that none of this was magic. My program exploded because it had a legitimate bug. The compiler was complaining about a syntax problem and it was smarter than me. None of this is magic; every bug can be fixed. Also, it left me with a huge confidence that I could learn any programming language easily. I wrote one and made the compiler that turned it into executable code -- of course I can learn dozens of programming languages.
- What was the job search like after completing your degree? Did you feel fully prepared when making the transition from school to the workplace?
UW-Madison was a program that was heavy on theory at the time. I had classes in algorithms and compilers and operating systems and artificial intelligence. I also had about 30 credits of math. While there was a lot of mental gymnastics to overcome, and I had a lot more experience coding than most of my peers from my hobby projects, I was pretty surprised about how little I knew about programming at a company with a large team of developers.
I needed to learn to actually design my code and not just start typing. I needed to learn about source code control and tagging. I needed to learn how to thoroughly test my code, and write code to test my code, so my peers wouldn't be negatively impacted by a nasty bug I checked in. I needed to learn about regression testing and making sure my new code didn't blow up some old process.
I also needed to learn how to accept constructive criticism and learn that my code isn't my sacred baby. If it sucks, I needed to hear why it sucked and that I needed to scrap it and start over.
- What are some of the challenges you face in your work on a day-to-day basis?
The biggest challenge when I was a professional software architect was balance. I wanted to be designing and writing code, but some other project that I had nothing to do with may have been blowing up in production and the company needed some fresh minds to look into the bug. Someone needed to deal with vendors and perform price negotiations for a database platform. Someone needed to spec out some hardware to make sure this website was really going to perform during a holiday push. Someone needed to mentor a young programmer. Someone needed to work with a business unit and gather requirements on a project that was of massive importance to the business unit. Someone needed to go to campus and meet with dozens of young computer scientists and recruit the next wave.
If you are a well-rounded person and personable and have any leadership skills, you are going to get pulled away from what you think you love to do sometimes. It can be what is best for the company and best for your career. I'll always look back at this part of my career fondly, but I don't regret that my career has taken me in some different directions.
- Why did you decide to start your own business?
I've never been a big fan of authority. While I had bosses who I respected, and I'm sure it isn't true, as a young professional I was always pretty sure I was about 10 times as smart as my managers. I had a similar thought process in third grade and probably in the womb. Irrational confidence and desire for independence.
But I was also out-hustling my professional peers. I'd be working 60 hours a week and one of my hours would produce five times the production of a normal hour from my peers. And, as a result, I'd get my 8% raise annually when I worked for traditional, large companies. They just were not set up to reward someone like me. It takes four years to become a team leader and there's people in line in front of you -- that kind of thing.
So, I bought a one-way plane ticket and flew out to San Francisco during the first internet boom. While I had a small amount of success at the startups I participated in, I knew they made a lot of mistakes, and [I] had that irrational confidence that I could do better.
My younger brother Tyler was getting his computer science degree from UW-Madison [and] had an idea to start a hard drive repair business, and we went for it.
- How has mentoring other programmers/computer science professionals changed your perspective on the field and/or computer science curriculums?
When I got out of school and into a career, my first thought was, "I wish they had some classes about programming in the real world." I was embarrassed I didn't know about GUIs, requirements gathering, source code control, and build processes. When I was mentoring young programmers, I'd often think about the same things -- "jeez, they don't teach any of this real world stuff in schools." And, I think in general, a lot of programs have heard that feedback and adapted.
Ultimately, I think it is probably the wrong move! Looking back at the more theoretical University of Wisconsin program, where you really get pushed to understand the core concepts of building an operating system from scratch or building a programming language from scratch, learning about logic gates and doing some CPU design ... it really sets you up to help drive what comes next in the world of computing.
There're thousands of people who can go to a tech school and learn Java and become proficient in a handful of years -- good enough to work some corporate job at a bank. A curriculum that drives bigger-picture thinking and fundamentals, the stuff that isn't directly used in some of those real world jobs, is a better longer-term investment for people who want bigger things from their careers.
- What advice would you give to students who are considering a degree in computer science?
Learn to program first. Buy a book and become a Java certified developer before you take even CS 101. If you love it and have a mind for it, you'll be able to get through a self-guided curriculum and know that you'll have the enthusiasm to make it through all the academics. More than that, while your peers in those classes are taking 10 hours to knock out a program and stumbling around with trying to understand what a "null pointer" means, you'll rock out working code in two hours and be able to spend your time thinking more about the theoretical stuff.
And, you might have time to start thinking about more entrepreneurial ideas. Might have time to work on your hobby projects, which to a savvy interviewer are a lot more important than any academic project you may code.
You also might find you absolutely detest programming -- don't have the patience to sit in front of a computer having a compiler kick your teeth in for five hours at a stretch. So, that $50 book will have saved you from a ton of time and effort and money getting into a highly competitive CS program! Great programmers have a streak of independence and a willingness to be self-taught. If you require an instructor to be jamming assignments down your throat in order to be successful, you'll never actually be successful.
