What I've learned from my mistake.

Last week I made a mistake. I confused the meaning of private/public key and their usage in asymmetric  cryptography algorithms.  I understood my mistake and excused to my colleague with whom I talked. So in the first moment when I understood that I did a mistake I was angry on me. But when I got calm I remembered that I could apply the last posted principle of the software monk. So I started thinking why I made this error and what can I do to not repeat it this mistake and even how can I escape problems with confusion of my knowledge? I considered the situation and understood that I change the knowledge domain almost every week. For the last 2 or 3 weeks I had to start implementing code on Python and Java, modify servers implemented on Python and C which I didn’t know very well and so on. This facts hints me that I have to cut these kind of problems to the root. My decision which I found out for me was to start making a brief review of the basic concepts in every new area where I am making new steps or I haven’t work more than a year. Probably this approach will cut my mistakes a lot. According to my colleague Mircho 60 to 70 percents. My experiment will show me what will be the result !
