Get some basic git stats on your lines added/removed ratio

These aren't the most insightful stats but sometimes I find it interesting to see what my ratio of lines added to deleted is, and you can do it with just one command.

Simply run the command from this snippet and you'll get your 'Lines added', 'Lines deleted', and 'Add./Del. ratio'.

Don't forget to replace my name with yours, if you're not sure what it is you can just run git config -l | grep user.name

Find out your Mac's average daily usage!

So I got curious about how much value I've gotten from my Mac and decided to write a script that would tell me how many hours per day I've averaged since I got it, as well as how many days I've had it.

The final script isn't perfect but it's on npx so you can run it directly from there by just doing npx mac-usage-stats.

You can view the code on Github.

Unfortunately there is one tiny dependency, but there's a chance you have it installed already. It's a command line tool for Mac that helps you get hard-drive info called smartctl, which you can install very easily.

Alternatively if you prefer, I originally wrote it in Python and you can use that too!

I find it really interesting to know how much I've used my Mac over four and a half years, and now you can too! ☺️

I wrote a python script to output your Mac's total (and Daily Average) uptime since you bought it!

So I was curious about how much value my MacBook Pro was in a money-per-hour kinda way and decided to find out how many hours I'd used it for since I bought it.

This turned out to be relatively straightforward as some commands can be run to get the info we need.

The first thing we need to do is find the age of the /private/var/db/.AppleSetupDone file which gets created when the Apple setup is... done (🔝 name for a file tbh).

Then we get the number of hours the OS hard drive reports being used for. This limits things if you've replaced your hard drive but I'm not aware of a way around this.

From there it's some pretty simple maths and we have the answer!

The code is here on Github

I haven't spent a huge amount of time working on this so there could be better ways to do any of it, PR's welcome 😊
