When Rebooting Is Not An Option
from the figuring-out-where-the-problem-is dept
It's a standard refrain. When anything goes wrong with your computer, the first thing everyone expects you to do is reboot and see if that fixes the problem. However, as computer systems and networks become more ubiquitous and more decentralized what if you can't reboot? If your entire home is automated, and the phone suddenly stops ringing, do you restart the whole house? What if it's a problem at your neighbors that's impacting your house? The article is interview with Larry Rudolph at MIT, looking at some of these issues. Rudolph is trying to work on systems that will help to detect where the problem is, thus making it easier to repair. Right now, when there's a problem, it's often difficult to tell what's causing it - and that only gets worse when you have more points of potential failure. He also makes a good point about how wireless makes this all more difficult. When everything is a wired connection, you can easily disconnect wires to try to isolate the problem. When everything connects automatically, you no longer have that option (or, at least, it's not as simple to disconnect).
Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

Ever heard of QNX?
I'm not an expert on OS's, but it sounds like microkernel OS's for embedded systems have been around and don't require "reboots"...

hmmm
Well, we may have had a power outage or two, but since the linux distro is on a write-protected floppy, it hasn't meant much trouble.
