The stock weather widget preloaded on your Samsung Galaxy S4 is really great, but there's one thing that's missing—options. The weather widget shows just the right amount of information at a glance, and it's not too shabby looking either, but for us softModders, it'd be really ...more
If you read my article on the OSI model, you got a good overview on communications from that model's perspective, but how does that relate to TCP/IP? We're going to take it a step further, getting into the idea behind the two address concept. How does an IP address and a MAC a ...more
