>Thinking back to it, I wonder how I was able to use ssh and tools like grep, ps and kill but did not know how to operate basic vi ... This has become a recurring thing for me to the point where I sometimes feel like I'm not as intelligent as I used to be. I'll need to look at requirements around older existing code, so I use git blame to see the commit history. It occasionally leads to me to some older code that I had written, and sometimes I marvel at how I was able to figure out or troubleshoot the issue. One of the earliest examples in my professional career is using Threads. I had an academic understanding of threads. My practical knowledge around them was dubious at best. With the help of Stack Overflow and lots of web searching, I cobbled together a thread manager that can spawn separate threads for asynchronous web requests and kill a web request after X amount of time. I even made sure that error handling redirected gracefully should one of those threads get killed. That code (with no changes to the core functionality) still exists to this day.
