Smart Power Strip Revived with Raspberry Pi
We’re all for buying broken stuff from eBay to save yourself a few
bucks: buy it cheap, fix it, and reap the rewards of being a step ahead
of the average consumer. Searching through the “For parts or not
working” categories is nearly the official pastime here at the Hackaday
Bunker. But buying an eBay find only to have it give up the ghost in a
couple weeks? That hurts. That’s
precisely what happened to [idaresiwins] when he bought this beefy

Firewalls are becoming increasingly important in today’s world. Hackers and automated scripts are constantly trying to invade your system and use it for Bitcoin mining, botnets or other things. To prevent these attacks, you can use a firewall on your system. IPTables is the strongest firewall in Linux because it can filter packets in the kernel before they reach the application. Using IPTables is not very easy for Linux beginners. We have created easywall - the simple IPTables web interface . The focus of the software is on easy installation and use. Access this neat software over on github: easywall
When building a DDoS mitigation service it’s incredibly tempting to think that the solution is scrubbing centers or scrubbing servers. I, too, thought that was a good idea in the beginning, but experience has shown that there are serious pitfalls to this approach.
