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

I needed to use SQLite from php to develop a WordPress plugin. (Yeah, yeah, I have heard most if not all the jokes about that particular stack.) Here are some notes about my experience, offered to anybody who might be able to use them. htt

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

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 t

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

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.

There's a book by Jen Pahlka called Recoding America. https://www.worldcat.org/title/Recoding-America-:-why-govern... Germany seems to have similar sorts of federal / state / municipal government issues

XML and JSON are for serialization. zip and sqlite, and file-system files, are for lossless persistence. They're separate issues. An app can go bananas with serialization and use, I dunno, binary JSON or Matroska / ebml or .mp4 c

When I'm coding / debugging with a framework of some kind (nodejs, dotnet, jdk, wordpress, whatever I'm using to deliver value at the time) I sometimes "step into" the framework or a library to see what happens. (Of

People working in science have employed this process for a long time. Hit your local academic library and look for periodicals called "Annual Review of whatever". More generally, look for review articles and you'll see their

One wonders about gut biome and whether any microorganisms there have any effect on this. One also wonders how humanity can adapt to dramatically extended lifetimes without obliterating our planet.

What could a YC-style startup do for construction? A lot of stuff is already done. There's total standardization of parts sizes, and has been for decades. If you order a 2x4" wall stud from your local lumber yard, it will be the s

And every time this happens from now on, the fine should be doubled. When the fine gets too high for the lazy lawyer to pay, they may instead relinquish their bar admission (lose their license to practice law) for five years. Lawyers admitt

Right. And all the GPL, MIT, and CC Sharealike-with-attribution material I've been stashing on Github is going into the vast code anonymizer called Copilot. The good news for me the open-source developer: it looks like the closed-sourc

As an experienced (===old) developer, I have learned that data long outlasts the programs that access it. The lifetime of data is measured in decades, but programs last for years. Most SQL-based RDBMS teams have figured out workable version

I take the author's point for single-user write-frequently search-rarely use cases. Plenty of small greenfield projects look like that. Bigger projects, or projects that are enjoying fast growth, may well need indexing. Why? to keep s
