Good material!

It has to be said, the order of columns in correctly designed multicolumn BTREE indexes is governed by the shape of the queries the indexes support.

So don't arbitarily reorder columns in your indexes to handle alignment.

In my time as a biochem undergrad and grad student, I had to memorize and regurgitate the Krebs cycle no less than four times. None of those romps through it addressed the question of how TF did those scientists figure it out.

There's the science of Karl Popper, where no statement can be considered scientific unless it is possible to devise an experiment to disprove it. And there's the science of education, where we memorize and regurgitate stuff.

Those two are stunningly different from each other. Yet, it's not possible to get to the mysterious work of actually doing Popper-level science without memorizing what went before. The critiques of this paper still ring true half a century on. I wish more students of science from primary school on up would pester their teachers and each other with the question, "how do you know?"

FWIW, the XML signature stuff in dot net just works. Once you get dot net's XML stuff itself working.

Looks like some web designers in law enforcement are having some fun making fun of the cybercreeps.

Dang, Rachel, you must have had a rough day at the orifice that day. Condolences.

Let us not forget his collaborator, Amos Tversky, who died young in 1996, and who certainly would have been a co-prize-winner had he lived.

This is great.

I wish it worked with glass :-) :-)

I sometimes sweep up broken glass from bike lanes in my community. I need gloves, a broom, a dustpan, and a trash bag. Not as efficient. Needs a car, not a bike.

Read about what to do: _The Fifth Discipline_ by Peter Senge. A bit dated by now, it's still good stuff about "systems thinking" . And you'll need a lot of deliberate systems thinking in your job, and you'll need to teach others to think that way.

Read about what not to do: _The Ultimate Question_ by Fred Reichheld. This book is about the notorious Net Promoter Score. (Would you recommend HN to a friend? Would you? Would you?) Reading it will give you insight into how bonehead MBAs with Cs in their marketing classes can convince leadership they've come up with a good way to measure customer satisfaction. (Net Promoter Score works fine for competitive businesses selling commodity products -- rental cars to individuals for example -- but not for many places where it is now used.)

It would be great to get a straightforward assessment of the improvements in reactor tech in this new plant. "Passive safety features" sound pretty good to my untrained ear. But how much of this is marketing bullshytt?

Cool! The 11/70 I worked on had a defective floating point unit for a while; when it overheated it would start garbling MUL results. I don't suppose this has that "feature" :-)

In wood shop in school, they teach you to use the saw, screwdriver, and tape measure before they say "make a box". Why not in programming shop?

One wishes there were a version of this article for science journalists.

And, one wishes that a university class on scientific ethics asked students to read this article with a critical eye and figure out what they can learn from it.

Myths about human-health topics spread faster than truth sometimes. cf. stomach ulcers and "stress" vs. pylobacter. It's hard to stop that. But it's easier to stop if we're aware of the myths.

It has to be said, web dev got better when the Redmond Middle School science projects (Microsoft Internet Explorer and old Edge) went into the dustbin of history where they have long belonged.
