This is a compiled list of falsehoods programmers tend to believe about working with time.
Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

You are looking at the most important, and most abundant thing on the web. You can't see it, unfortunately, because it's very small… aaaaand it's invisible — so having a magnifying glass doesn't really help here. But still.
I'm talking, of course, about U+0020; not to be confused with the band U2, who are just as ubiquitous, but far less useful.
This unicode point, representing the humble space character, is between every word, in every run of text, on every page of the web. And it has a very special characteristic: it's not sticky like glue. If two words are neighbors but there's not enough room for both of them, the space will free the second word to wrap around and start a new line.
Before getting into flexible containers, viewport meta tags, and @media breakpoints this humble character is what makes the web fundamentally 'responsive'. That is: able to change the layout of its content to suit different devices, contexts, and settings. Browser text does this automa
So there were a few threads going around recently about a challenge to write the longest sequence of keywords in Javascript:

In honor of the 30th anniversary of the web, I wanted to share a few thoughts about what a better web could aspire to be, and challenge us to move toward it.
It's tempting to frame "better" simply in terms of improvement and progress, as in how far the web has come over the last 20+ years. As a developer, I like many others get all too excited about fancy new features like Service Workers, WebRTC, and yes, even CSS Grids. The pace of change is dizzying, but it feels like a great problem to have too many awesome features to learn and use!
So in one practical respect, a better web is one that empowers developers and users alike to express themselves and connect with others more fluently.
