Finding our difference between files is a common thing I used to do. For most of the time I had the trusty k3diff. Things got messy with command line and scripting the difference job. I am not sure how many times I searched for diff command linux in Google. Also, do manual patching not knowing the patch command was a handicap.

Hence after much spite, I have decided to log it down here.

Secure Raspberry Pi

Using Raspberry Pi for your IoT experiments - a given. Like the white hair on my head.
Many don’t realize the real threat it poses these days to security. There have been many reports of IoT devices being hijacked. And then used for malicious purposes. Like peeping into your drawer. Even worst looking into your code. I don’t want people to know how many cockroaches and worms lie hidden in my old code. ;-)

Well, instead of loosing your night’s sleep read this.
