Quantum spin. Electrons aren't really spinning, right? But why do we call it spin? I know it has something to do with angular momentum. What are the possible values? Is it a magnitude or a vector? Is there a reason we call it "spi

I have a late 2013 Macbook Air and I love it. I do most of my work on a Xubuntu desktop, but the Air is great for travel, working outside, or carrying around the house. I use it every day. I bought it to replace a heavy plastic dual-boot De

Back in 2000 I was a new college grad doing manual data entry as a temp in Boston for 1200-page industrial supply catalogs, wishing I had majored in CS instead of English. (I've programmed since 8 and by then I already knew BASIC, Pasc

Can an MS SQL Server expert explain why creating table variables inside sprocs is so popular? I've done lots of Postgres & MySQL (and long ago lots of Oracle), but now I find myself maintaining some MS SQL Server projects, and I se

I've done this before with good results. I was pleased to see they are using `SELECT FOR UPDATE SKIP LOCKED`. That is what this 2nd Quadrant article recommends, which I think is required reading if you want to implement this yourself:

One of my favorite tricks is to generate the JSON for your API responses in Postgres instead of in Ruby. You can get 100x speedups, but the downside is that you wind up with big nasty SQL queries that duplicate Ruby logic and are hard to ma

Isotope is a pretty fun jQuery plugin: https://isotope.metafizzy.co/ An idea I read about long ago is ring-based context menus. So instead of getting a square list of choices, one per line, you get each choice arranged in a

Nice writeup! The nasty part is that you don't get an error, you just get wrong answers. You might not even notice for a while. Such bad news!

I was an English major in college, so maybe I'm taking some background for granted here: no one expected that good poetry had 5x14 da-DUMs without relief. (Certainly you wouldn't want to force Shakespeare to sound that way when yo

Hey this is cool! I tried Shakespeare's Sonnet 29 and it thinks only half the lines have the correct meter---which partly goes to show how flexible real poems can be but also could highlight places your tool could be refined. I think l
