I think this emperor has no clothes! Take distributed concensus protocols: two-phase-commit (or RAFT et al). I have never worked in an organization that adopted a 2PC communication protocol. The only real-world example I know is a wedding c

I'm sure it's willful blindness on my part, but in 30 years, I can't think of a single example of a design I've helped create that was a reflection of the organization's communication structure. I've built obje

And here's a trick. It works for me, but not others. Einstein and physics say we live in a space-time continuum. The past and the future are just different points, different places. What you've done already, where you've been

When my wife died, death lost all of its teeth for me. It's not worth the price, but losing someone you love pretty much solves the fear thing. The valley of the shadow is a scary rollercoaster on the way in. But on the way out, it&#x2

I'm 59 and based in New England. I worry about this all the time. But so far, the worry has been a bigger problem than the reality: I've left stable employment situations to start up my own things, thinking that was my best insura

One reason is when the investors own > 50%, control the board, and decide to recoup 10 cents on their dollar. But I've known entrepreneurs who made the decision independently, feeling it was the right thing to do. And it is the righ

I looked at sick time a couple of years back and noticed that when a frequently sick person stayed home sick, another frequently sick person followed suit within a day or two. I wonder if anybody has a Pearson correlation on that.

Actually, CryptDB does (or at least did originally) use homomorphic encryption (HE) for evaluating SQL arithmetic expressions. While the earliest suggestions for HE were terribly slow, CryptDB found one that was practical. If memory serves

I wonder if we're evolving scoring systems right now. Not so much with hackathons and sites like codefights.com but through data mining github. I'm thinking of a recent post to HN in which successful github projects were correlat

I'll second this. In my case, fear of famine (which never actually happened) often led me to take on too much work to have a side project. Sometimes, I couldn't do as good a job on concurrent projects, but was afraid to do thing
