Men’s Java is not JavaScript Annoyed Programmer/Developer T-Shirt
Posted by jpluimers on 2020/05/13
Though the shirt is not available on Amazon [WayBack] any more, still – after 25 years – so many recruiters still get it wrong.
Not just recruiters, so: [WayBack] Why is JavaScript called JavaScript, since it has nothing to do with Java? – Stack Overflow, thanks to CMS [WayBack]:
From an interview made to its creator Brendan Eich:
InfoWorld: As I understand it, JavaScript started out as Mocha, then became LiveScript and then became JavaScript when Netscape and Sun got together. But it actually has nothing to do with Java or not much to do with it, correct?
Eich: That’s right. It was all within six months from May till December (1995) that it was Mocha and then LiveScript. And then in early December, Netscape and Sun did a license agreement and it became JavaScript. And the idea was to make it a complementary scripting language to go with Java, with the compiled language.
he continues on the relation of ECMAScript based languages:
JavaScript, was originally named Mocha, later it was renamed to LiveScript, and then to JavaScript.
The LiveScript to JavaScript name change came because Netscape and Sun did a license agreement.
The language was then submitted for standarization to the ECMA International Organization. By that time, Netscape didn’t allow the use of the “JavaScript” name, so the standarized language is named ECMAScript.
JavaScript isn’t actually an open name. Now it’s a trademark of Sun (now Oracle).
There still a lot of confusion, some people still think that JavaScript, JScript, and ECMAScript are three different languages.
ECMAScript is the “standards” name for the language.
JavaScript is technically a “dialect” of ECMAScript, the Mozilla Foundation can use “JavaScript” as the name of their implementations (currently present on the Rhino and SpiderMonkey engines).
In the early days, Microsoft decided also to do what Netscape was doing on their own browser, and they developed JScript, which is also an ECMAScript dialect, but was named in this way to avoid trademark issues.

Updating Actions (Don’t Do This) – Dave’s Development Blog
Posted by jpluimers on 2020/05/13
I remember fixing a high CPU toggling the Enabled property in an OnUpdate even handler on a TCustomAction descendant quite some time ago, but wasn’t completely sure of the exact cause.
My fix was to only set it once every clock tick (about every 20 milliseconds).
The best fix would have been not to toggle at all: just calculate the right result, then only set the Enabled property once: [WayBack] Updating Actions (Don’t Do This) – Dave’s Development Blog
