System administration *

If you are working with Kubernetes environment then you probably make use of several existing templating tools, some of them being a part of package managers such as Helm or Ksonnet, or just templating languages (Jinja2, Go template etc.). All of them have their own drawbacks as well as advantages and we are going to go through them and write our own tool that will try to combine the best features.

Monitoring is the most important part of your infrastructure. Monitoring is system engineers basics. However, everyone has his own way to understand it. My way consist of denial. anger & acceptance.

I always loved playing with things and testing them under all sorts of wacky conditions as a kid and even considered getting a job as a tester, but I never did. Nevertheless, I still like taking things made by someone else and poking them for vulnerabilities.

I remember, when first self-service payment terminals started popping around town, I saw one of them put up a browser window while updating, and the game was on — I broke it almost immediately. There’s been a lot of discussion about it since then and developers have started to pay a lot more attention towards security in these machines.

Recently, fast-food joints have started installing these terminals. Obviously, it’s quite convenient: just tap a couple of virtual buttons, place an order, pay with a bank card and wait for your number to show on the screen.

Also, nearly every big mall has these interactive boards with floor plans and information on various sales and discounts.

How secure are they?
