Change Change is a process where someone change something. According to google, “make or become different”. It doesn’t really mean that it’ll be better. Improve Improve is a proccess where we take what we have and introduce a change to make it better, which can be measured by the key metrics. Changing a bad proccess I think it’s makes absolutely no sense. Any proccess that exists, must have been evolved from something, to the current state.
My favourite interview questions
My favourite DevOps tech interview questions so far by “my favourite”, I mean, things which I think may help to determine if the employee have the necessary skills, a mindset which fits into the company culture, and the likelyhood of a win-win outcome of an employment relationship. General understanding describe what happens when you write http://www.<companywebsite>.com into the browser I think it’s a great open-ended question, experienced engineers can talk about it for hours.
setup cjdns mesh network on rpi
Why it is cool The goal here is to make my PI reachable from everywhere, no matter where is it. It’s not like publishing it to the internet, it’s a private network, currently not connected to any external peers, which helps to reduce the attack surface. Think of it as VPN service without any central servers, nodes just connects to each other, and they can reach each other by discovering routes, so if any node breaks down, it will be just that node, and the rest of the network will find an other way around.

Building a NAS from Paspberry Pi
The beginning I’ve received a PI from my Friend; he was also interested in building a simple and cheap NAS. I’ve got this: https://thepihut.com/products/raspberry-pi-zero-essential-kit (roughly 1.900 HUF as the time of writing). Getting the hardware The first days was mostly about reading the docs, and understanding what do I need to achieve that; so I’ve created a list, to see what do I need to make it happen. Power adapter (actually, I didn’t had to buy it, as it works with my phone charger) Active USB HUB (the PI doesn’t have enough power for storage / networking / display / etc), and I wanted to make sure on that won’t be a bottleneck.
