Trust me: You WILL notice the changes, especially if you fly in at night. There are so many more casinos and theme parks than there were when you were here, last. The streets are much wider and MUCH busier, and depending on where you stay, people are ruder.
You’ll have fun, though, because there are lots of things to see for free, depending on the amount of free time you have.
It wasn't until several weeks later that I found the problem, and then by accident. I had had an oscilloscope hooked to one of the machines' main voltage supply, and out of the corner of my eye I thought I saw a very brief pulse downward while the machine was booting. After many tries I found the 'scope settings that would show it and... sure enough, my boss had designed the power supply with very slim margins (to save cost), and there was an instant in the boot sequence where more power was needed than the supply could provide, so the voltage dipped barely into the region where the processor could become unstable. grrr...
That's my main memory of Las Vegas. *\;-)
Don't know how much time I'll have free. Little during the days, likely, though evenings may be possible.
