Backend developer. Main side project is Tablesaw, a dataframe for "large" data (100M to 1B rows) in Java ( https://github.com/lwhite1/tablesaw ). Although, it might be better described as a personal, in-memory,

The target scalability for this version is ~2 billion rows on a server class machine. Right now 500 million is about the best you can do with reasonable performance on a laptop.

I'm assuming we're talking about output measured in the real world. At the forth standard deviation you might be 1 in a million, but you're still not outperforming an average person by 10X.

the popular claim is 10X better than average. Not 10X better then suck. And definitely not 10X better than a total newbie at the one thing you've worked on your entire career.

I think if you read the original, the choices discussed were personal happiness vs money and status. Choosing happiness in that context is wise, not selfish. Also, I think you're confusing happiness with the pursuit of pleasure. Most o

Then don't run engineering teams :) - assuming you can code. When I realized most software companies treat engineers better than they do managers, I switched. I actually can't recall a single employer who didn't treat the en

Sadly, you must have other goals besides personal happiness. But given that you only live once, why would you prefer a different goal?

Not sure Microsoft in it's heyday was a great engineering culture. The were a monopoly, which allows bad engineering to occur without ill effect for a long time. I think many of their problems today are due to being tied to code writte

There is no such thing as culture of "DO fuck up", only cultures where avoiding mistakes is secondary to other goals like hitting the schedule date.

10X programmers are unicorns. If a 5K of 12:57 was really "10X", an average runner would take just over two hours. That performance is nothing like 10X.

Have all these changes made you happier? We all love status, having influence, etc., but are you actually enjoying work more than when you were coding? Many times the status comes with so many strings (and responsibilities, and headaches) a

What's truly ironic is that the "Don't be evil" company bought a DoD contract robotics company in the first place. It was obvious all along that robots like the Chetah were designed to push the state-of-the-art in robots

Um. I'm not entirely against hunting, but first came the hunting; then the animal-control justification for it. You could argue that it might be wiser to let nature take its course, but hunting is popular and game is delicious.

Git is the worst piece of software I actually use. It is impossible to use safely and without headaches unless (a) you only do the same, simple things every time, or (b) you're an expert. And yet, pretty much all programmers have to us

They don't. US companies mostly hire remote workers in India and China, not in the US. When they do it overseas, they generally work with a local company to make the legal and logistical aspects simpler.
