 Topic of the day:  What is an "Expert"?

• The Expert: https://youtu.be/BKorP55Aqvg
• The name on the frame is Expert: https://www.youtube.com/watch?v=B2XQN-Yz9EM
• If someone else says you are good at something you may be an expert
• If you think you are good: https://www.britannica.com/science/Dunning-Kruger-effect
• Finding 3 BILLION unnecessary queries might mean you are an expert.
• Added a cache in front of the db
• Saved a week of cpu time every 24 hours
• This was about 1/3rd of the queries
• Shadow ops are easier when nobody is looking.
• regexing for xml tags means you probably an expert (at causing yourself pain)
• Oh by the way, intellij has regex tester (a la regex101) built in
• Using string interpolation to insert comments making conditionals in your sql query might mean your an expert
• or it might mean you like pain
• March is not far from January
• learning to estimate
