No comment to add. Tortoise is so great, no linux tool get close to tortoise svn!
Came here to say this, but you beat me to. I do a lot of SVN tasks from within my windows VM because Tortoise is such a joy to use!
You have no clue. I've been running Amtrak trains for 18 years. There is no intentional speeding, over 10mph and you lose your federally issued lisence for 30 days, second time you get caught 6 months and probably won't have a job to come back to. That's all laid out in the CFR. Everything is recorded, no one would dare. Remember we mess up and we're right there in an accident with you. Here's what I assume happened from my experience. He was newish to that route, I've read 2 -3 weeks, thought he was somewhere else, sped up, realized it and dumped the brakes. It takes years to know a route.
