Programming

How did you lot acquire to program?

Some college, some self taught, to a greater extent than oftentimes than non on the job

Tell us nearly the most interesting/significant slice of code you lot wrote.

Cluster director (leader election + error detection/response) for HACMP/6000 inward 1983. Primitive past times today's standards, but cutting border for its time. Used inward production at a meaning pct of banks, retail stores, etc. for nearly a decade.

Who did you lot acquire most from nearly calculator systems?

Various senior/principal engineers at Encore when I was nonetheless junior inward 1990. It was i of the early on UNIX SMP systems. Learned much of what I know nearly kernels, TCP/IP, multi-processor synchronization, retentivity hierarchies, etc.

Who is the greatest programmer you lot met, together with what is impressive nearly them?

TBH some of the best programmers I've met worked primarily inward Verilog, designing chips together with tools approximately them - e.g. Wilson Snyder together with others at SiCortex/Veripool. Huge volume, but also rigorous testing leading to *very* depression defect rates fifty-fifty for that domain.

What exercise you lot believe are the most of import skills to last successful inward your field?

Communication/collaboration skills, with the caveat that i must last willing to work them for good. The skills themselves tin privy also last used for personal glory or to form/maintain cliques, which is non good. Drawing together people with complementary skills/interests (especially those who are under-recognized or under-utilized where they are) together with keeping them aligned toward a clear destination tin privy create a whole *much* greater than the amount of its parts.

What character or powerfulness exercise you lot value most inward a calculator systems person?

Understanding of what it takes to ensure that a particular type of scheme (e.g. non-DB storage for me) is right together with maintainable/operable inward the long term. Understanding how to blueprint a scheme (especially a distributed one) for these properties, where/how to apply diverse forms of validation or testing, etc. tin privy brand the divergence betwixt a scheme that serves both developers together with users vs. i that burns them out.

Personal

Which of your work/code/accomplishments are you lot most proud of?

Teaching some hundreds of others the value/importance of making code right earlier it ships, together with techniques to that end. The persuasion that I mightiness possess got helped improve systems that I'll never locomote on myself pleases me.

What comes to you lot like shooting fish in a barrel that others unwrap hard? What are your superpowers?

I seem to last meliorate than most at "visualizing" the the world of a scheme with many concurrently moving parts, together with anticipating what states it tin privy acquire into. This extends all the agency from debugging (finding the obscure sequence of events leading to an observed failure state) to developing novel algorithms for specific purposes.

What was a approving inward disguise for you? What seemed similar a failure at the fourth dimension but led to something meliorate afterwards for you?

Being set off from my kickoff programming task inward Michigan. It was sort of traumatic, but it led straight to me moving to where at that topographic point were *far* to a greater extent than kinds of programming jobs available. As a direct resultant of the physical move, I also moved from application-level programming to system-level programming - peculiarly networking together with distributed systems.

What exercise you lot experience most grateful for?

All the people who gave me a chance, from Karl Zinn at UMich's CRLT when I was nonetheless a scruffy pupil to the people who hired or promoted me, who invited me to beak at conferences, who persuaded me to atomic number 82 entire projects. In many cases, at that topographic point was lilliputian argue to believe I'd last skillful at The New Thing.

What made you lot most happy inward the terminal year?

Retiring. :)

Work

What was your biggest mess up? What was the aftermath?

It was sort of a slow-motion mess up, but existence production architect at Revivio (continuous information protection) was sort of a disaster. It was my task to exercise alignment betwixt iii other teams that were pulling inward dissimilar directions, then that nosotros could send a feasible production faster. I failed, inward large role because I focused every bit good much on the hands-on details together with non plenty on the large picture. There were reasons, at that topographic point were for certain others who contributed to a greater extent than to the outcome, but ultimately the companionship ceased to exist.

What was your most interesting/surprising or disappointing interaction at work?

On at to the lowest degree ii occasions, I had to locomote with engineers who literally but refused to exercise the things they were supposed to do, preferring to locomote on their ain alternatives instead. One eventually got fired for it, which was really educational for me. The other, fifty-fifty to a greater extent than surprisingly, never did.

What exercise you lot similar most nearly your job/profession?

The intellectual/technical challenges, of solving large sets of really difficult problems, making everything gibe together, together with (eventually) producing something of value to users.

What exercise you lot dislike most nearly your job/profession?

The cargo-culting together with factionalism, oftentimes driven past times the authorization of Big Money trying to create/sustain manufacture behemoths instead of good for you lot ecosystems.

What would last the unmarried alter that would improve your locomote surround most?

Adoption of remote-friendly communication methods together with workflows. "All inward i room at the same time" is but non going to last the primary model going forward, together with using video etc. to replicate that doesn't work. It's the shared-memory SMP model of work, together with it doesn't scale nether fifty-fifty moderate latency. Truly scalable teams possess got to covert asynchrony together with explicit communication, but few do.

Technical

What exercise you lot mean value are the hardest questions inward your field?

How to repose needs for unity/efficiency vs. isolation/diversity. At the technical level, this appears e.g. every bit microservices vs. monoliths, together with I've been approximately long plenty to run into both overdone. At the organizational degree it's to a greater extent than nearly squad structures together with workflows.

What are you lot most disappointed nearly the state-of-the-art inward your field?

As I said on Twitter, the focus on features/performance/profit over correctness/sustainability, *especially* with the organizations that are best placed to shift that direction.

What are the topics that you lot wishing received to a greater extent than attention? What exercise you lot mean value is a promising futurity management inward your field?

Somewhere there's an intersection betwixt correctness (formal methods, testing etc.) together with composability that needs to last explored to exercise larger but nonetheless integrated (and efficient) systems. Kind of similar the erstwhile "software components" idea, sort of series specialization similar the FPGA folks boot the bucket along claiming to enable at the single-machine degree but at a whole-system degree instead.

What is your favorite calculator systems paper? Why?

Probably the Amazon Dynamo paper. There's a lot that it left unaddressed, together with of course of instruction it describes a proprietary system, but it drew together a lot of previously disparate threads together with ready off an explosion of activity interesting to me. For a narrower focus, Karger et al on consistent hashing is but really satisfying intellectually together with has constitute to a greater extent than uses than anyone could possess got predicted.

What are the most interesting blogs/twitter accounts you lot follow?

Yours, of course. ;) Also Vijay Chidambaram, Eric Brewer, Brendan Gregg, Jonathan Ellis.
