Hello, did you ever taught about mistakes you did, in your career? I was asked once about mistakes I did at work. And it was funny because in moment I was asked about this. I simply could not remember any of my mistakes I did ever. But I was sure I did. I simply could remember even once. And I realized that so many times we are focus on how good we are and we forget about our mistakes that though us so much. Sometimes, funny, sometimes bad, sometimes maybe even dangerous. But in fact mistakes teach us a lot. So I try to remember some mistakes I did in my professional way. And I choose three of them to share with you here, that is it, no big deal, just three mistake stories…
The first one mistake story was when I manage corporate server with corporate database with all company data inside this base. I was young, very busy, and not smart enough to realize that array of discs with strip and mirroring called RAID10 it is not enough… as a backup of data… and when I went back to my work after some brake RAID controller simply brake, and it was serious, CEO of our company was scary, co-owners was scary, and I felt I am so stupid. Thankfully it was physical hardware RAID controller without encryption and one of my colleague help me because it was possible to read physical portion of data from pair of disks and connect data together. The power of simple bash script and dd command in GNU/Linux come to his mind. And he helped me, that was teach me to always have backup, no matter what ;).
Second mistake story is about job agreement and money. I was lucky to join once to one nice company and work with very good software engineers. The company specialized on build business banks systems and I was in the middle of the company with research and quality department unit. So it was nice and truth be told it was very nice workplace… except… money I get. When I talk about joining to this team some amount of money was proposed too me and I was happy because that was good enough to take care about my family that time. Unfortunately first day of my work I get job agreement with my salary cut almost by half. And I have no option to wend out from this situation and real mistake was to not sign job agreement before I resigned from previous workplace. That unfortunately mistake teach me a lot about this company and sad truth about Polish managers that cheat you if it is possible. Later I found that not only Polish managers used to do that… Anyway that taught me to never ever forgot about papers you sign and the importance of paper signing time before you start something.
Last one third mistake story was a long time ago. I was on college about third or fourth year of study. And I went for a first time to found some work for money. And because everyone at that time known about my GNU/Linus operation systems passion one colleague asked me. Can I help his boss and him in company he worked at with shaping bandwidth of the internet. It was in in one popular of that time Internet Cafe. The problem to solve was asymmetric connection to the Internet called ADSL that happens all the time when you have download with higher speed than you upload data bandwidth from and to the Internet, So you want to get data faster because you are doing it much often. But upload is not only for send data like email or something is also about acknowledges ACK of every packet and needs to be large enough for TCP ACK packets, right? That was the problem, shape the bandwidth for users to use Internet gently. And I went for a first and last time for conversation about work and I was so incompetent. I was not prepared to talk. I do not even prepare something to get experience before of that. That was embarrassed to me experience, went to job interview not prepared and not ready. It was shame kind of mistake. And that taught me never ever be improper or incompetent. And not feel this shame feeling never again or avoid it as often as possible.
So, that was my three chosen mistakes I did. Have you ever did something similar? Maybe you want to share here about that :). Please keep in mind that people grow and get lesson from mostly or sometimes only mistake experiences. Do you agree? Is that make sense for you?
