Being comfortable with basic back-of-the-envelope math can be a huge benefit. (Full disclosure: i am a math major who is now a programmer)

Over my career I have several examples of projects that have saved weeks worth of dev time because someone could predict the result with some basic calculations. I also have several examples where I have shown people some basic math showing that their idea is never gonna work, they don’t listen and do it anyway, and I see them 1 month later and the project failed in the way i predicted.

A popular (and wise) saying is that “Weeks of work can save you hours of meetings”. I think the same is true for basic math. “Weeks of coding can save you minutes of calculation”.

You can definitely be a successful programmer career without great math skills. Math is a tool that can help you be more effective.

Must include CHANGELOG…

The changelog:

• misc fixes
• pls work
• fixe a typo

Depending on your needs you can also break it into a columnar format with some standard compression on top. This allows you to search individual fields without looking at the rest.

It also compress exceptionally well, and “rare” fields will be null in most records, so run length encoding will compress them to near zero
