What are some lesser known items or tricks in your profession that most people don’t know about?
For me one thing would be Thrift drain cleaner. I was having issues with my drains being clogged and nothing really worked, but looking around on forums and advice from plumbers lead me to Thrift and now my drains work great.
HAProxy is really powerful load balancing software. Not only does it go above and beyond on features but it handles a really large volume of traffic on very little compute. For example I ran a site with 350hits/sec base traffic (that regularly bell curved up to 500hits/sec) on 4 HAProxy instances running on t3.micro EC2 instances and I was terminating TLS on 20,000 domains at HAProxy. And if you’re in a position where you need to pay for support they will bend over backward to help.
