When I first got my 3D printer, I didn't know anything about how it worked. I read a few articles and getting started guides, but I felt pretty lost. There was a lot of 3D printing jargon that made it hard to make my way all the way through any article about 3D printing. I felt like I was reading a foreign language. I trudged along and researched what each new word meant in the context of 3D printing, and I've collected much of what I've learned here.
I just got a new car with Android Auto, and I'm doing a little bit of work to make it work the way I like. The first problem with Android Auto is that it (mostly) requires a data connection for navigation. In this post, I add a hotspot with free data to my car that turns on and off automatically with my car.
I recently went car shopping, and along the way I got quotes from several different dealers. I collected three quotes that included price before TT&L and price after TT&L. After looking at the numbers, all I can say is that the price after TT&L is the only price that matters or means anything. (TT&L stands for tax, title, and license, but as you'll see, that's not all that it includes.)
If you're building a web app with ruby on rails, there's a pretty good chance you're using the will_paginate gem to make it easy to split a long list of items across multiple pages. If you have a couple hundred items, will_paginate works great out of the box. However, once you start paginating thousands and thousands of items, you'll start to run into performance issues. I'll show you how to fix them in this post.
