# Mateusz Frąk - Knowledge Base I started to see benefits of noting down everything I learn every day. Creating my personal knowledge base saved me a lot of time looking up for solutions of the problems I've encountered in daily operations. I've noticed I keep looking up for the same information over and over again, because I just can't remember everything. We are not the robots. Sometimes I just need 30 minutes to forgot how to create CSR, how to add rule to iptables, and many more even though I did that just a moment ago! We are consuming too much information nowadays. I wasted too much time of looking up for the same solution over and over again. I want to share my notes I do every day. It’s time to share it with everyone. >[!note] >Please keep in mind that all notes here are written using my words, my way of thinking. If you see something that requires correction, then I'll be happy to hear your feedback, thank you! I'll be posting new findings daily as well as old notes to keep everything in a single place. If my notes are helpful for you - tell me about this! If you are in doubt - don't hesitate to [contact me](mailto:[email protected]) directly, thank you!
