I, like many other people, enjoy changing the scenery from time to time and working on a laptop. Now, since I work on kernel drivers, I face some unique issues sometimes when working remotely that you just wouldn’t think about when doing application development or web development. One such issue, and the subject of this article is the problem of hanging on reboot.

tl;dr - If you’re unsure whether your machine is going to reboot properly while you’re working remotely, echo as root the characters r, s, u, b separated by a few seconds

cp …; ./do; Or how go executables are awesome and portable

Today I finally got around to starting up the small webservices that usually run on my main desktop after a short interruption when my first generation SSD had started corrupting data and dropping inodes every time I powercycled the tower.

It took a while to get my OS (arch linux), environment, database (postgresql), message queue server (rabbitmq) and other sundries up and working.

The problem with that is I’m trying to predict the future needs of my application and that’s a Very Bad Thing. I need to find the simplest thing that works and code that.

My natural instinct when I see a horrible mess of code is to figure out the original intention then rewrite and refactor. Other peoples’ code is an easy target for me to dig into and modify and I enjoy banging my head against things. When I started thinking a bit about this, it came to me that maybe
