Modern file hosting sites?

I have created a blog. I know, I know, I'm finally embracing the recent past.

Anyway, blogspot doesn't let you upload data files or anything other than photos. I need some recommendations for sensible file hosting sites that are reliable and secure.

I'll be uploading open source designs for software and hardware (code and schematics).

So what do you guys use, eh?

What I see used a lot on blogs is Dropbox.
It has a public folder that can be accessed directly.

Github!

Edit: Oh, I am not using it right now, but planning to use it in near future.

* Box.Net is pretty good.
