This reminds me of one of my first programming jobs as external consultant for the Baggage Handling System at Schiphol in 2000&#x2F;2001, I was 17 years old.<p>My employer at that time was using MS Excel to parse the log files of all sensors of the predecessor&#x2F;older part of the system that is shown in this video. I told her that I could probably do it 10,000 times faster by creating a simple program in Visual Basic.<p>Visual Basic was way too slow on our &quot;high-end&quot; Pentium laptop to parse that many 1MB log files, so I rewrote it in C++ (learned it on the job)[1]. The managers got insight in the performance of the various components of the system which they never dreamed of having (they were hardly aware that the system was creating this detailed log messages).<p>By the way, the system is developed (at least partly) by Vanderlande [2].<p>[1] Took me a couple of days, probably even weeks back then. I would write the code in 1 or 2 hours now.<p>[2] <a href="https:&#x2F;&#x2F;www.vanderlande.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.vanderlande.com&#x2F;</a>
