Slug – Tips

Reducing Memory Given that it has only 32MB of RAM, NSLU2 runs Asterisk as is very well, but if you want to add more daemons you might need to miser down on the memory. Dropbear Dropbear consumes only 2.4MB vs 8.2MB of SSH (who would've ever thought I'd be concerned about savings of 6MB of... Continue Reading →

I needed something which would consume less than 100W of power and cost less than $100. My runner ups were... Continue Reading →
