I suspect the only reason you see the word “entity” in computer science and such places is that, in school, we're taught not to use the word “thing” because it's not specific enough, it's too ambiguous.
So, I claim that when a person uses the word “entity,” they are trying to be ambiguous without being ambiguous.

A Forgotten Principle of Compiler Design
from Programming in the 21st Century.
That a clean system for separately compiled modules appeared in Modula-2, a programming language designed by Niklaus Wirth in 1978, but not in the 2011 C++ standard…hmmm, no further comment needed. But the successor to Modula-2, Oberon, is even more interesting.

Instant Web Server on Amazon (AWS) S3
Well, I just tried it and it worked! If you needed a quick and easy web server set up, you could grab a micro instance of a virtual machine on Amazon Web Services (AWS) EC2 service, set up Apache or similar, etc.
However, it's much easier than that. S3 (Simple Storage Service) lets you serve files, including static web pages, directly. You create a bucket, upload files, set permissions, set up logging, and you have a web site. It's free unless your web site has a huge amount of content.
Of course this is static, i.e., there's no PHP or programming, or dynamically generated pages here. This is just a simple site, but it works quite well.

The Beatles on American Bandstand
When I think of American Bandstand, I always think of watching this very show in 1967 when films (like videos!) were premiered for Penny Lane and Strawberry Fields. (From Video Cabinet in Limbo. It looks like the actual music videos have been removed).
Here are color versions of the videos. The ones on AB were in black and white.

Strawberry Fields (Another B&W version)

Why Have I Disappeared from Facebook?
Or at least, why am I not responding?
I have a few FB accounts and it seems that FB has decided I need to provide a phone number to keep them active. Right now I can't log into most of them without providing a cell phone number. I'm generally put off by this whole development and mostly inclined not to provide any information like that and just leave FB, at least on those accounts, behind.
For anyone who wants to read what I have to say, the good news is that I usually only post on FB an echo of what I post here. You can always see what I have to say by reading this blog. You always could.
Similarly, I've provided easy and effective ways to contact me. You can, for example, use those to comment on or follow up on my postings here.
What I am missing out on are some postings and pictures by folks on the locked FB accounts, and even occasional messages. Right now I can't reply to any of them and can't see many of them.
For most of the time I've not been a fan of FB and I'm less a fan than ever right now. Who knows, though, they may yet emerge as the preferred way to communicate and stay in touch. I expect the future holds some interesting surprise that I haven't imagined.
In the mean time, if you're looking for me, I'm still here where I've been the whole time. That's the nice thing about centering communication, at least the outbound kind, on one's own blog. You always have control of it and it can persist beyond the limits and misdirections of other services.

New Look
Well, now I've gone and done it. For the first time in some six years (I think) I've changed the look of the site here. I may make more changes over the coming days as I sort this out.
The site was looking a little old and, frankly, I didn't really like the current version of the look. I did like the fonts, colors and general layout.
However, I'm clearly a fan of the lighter and more open looks and this one is an example of that. I like the days being grouped this way.
I spent some time poking around with the text font. This is currently Open Sans (I think).
