  • For sure, anyone who has seen some of the videos of drink carts and luggage bouncing off the cabin ceilings during crazy turbulence shouldn’t have any questions about the utility of seatbelts in less than catastrophic events… Which of course is the goal even in ‘crash’ landings. There are crashes where seatbelts would obviously be worthless, but in anything short of that, you’ll be happy that you weren’t in a box with 300 human shaped dice being shaken up.

    It doesn’t require suspension of critical thought when you can look around the world and see that nowhere does anyone have high speed rail spanning distances and population densities equivalent to what the US would need to go from, say, New York to LA, it East to West Coast in general. There are plenty of examples similar locally to East or West Coast population centers, but nothing in between. High speed commercial routes? Maybe. High speed commuter rail? It’s not even close to being worth the cost: utilization.

    Not sure what you are arguing with exactly, theres a huge difference between commercial and commuter ‘profitability’. Things that freely allow for commerce like a road can be justified from many different direction where a periodic service only makes sense based on demand. That isn’t to say that maintaining an underutilized route with the goal of it becoming utilized based on is availability is always a bad idea, but a road can be built and it’s cost can at least roughly be correlated to it’s use. If you had to periodically rebuild every road, at roughly the same cost whether it was used or not, they would end up with the same ‘profitability’ concern, but mostly you have to build all the roads for minimal usability and then spend the most money on the most used roads. Freeways are understood to improve commercial visibility and are funded by taxes for that reason. The entire country benefits by having clear routes for good to move. Commuter rail primarily benefits a local area and is funded heavily by fares and local taxes.


  • A benign scan could just be looking for an ftp server to connect to or a repeater or relay server of some sort. There are plenty of open services people make available for free and the fact that you would consider it an attack it doesn’t make it one.

    At minimum you could be alerted to look for someone attempting to connect to your ftp server with a single basic anonymous authentication vs someone flooding that port with known malicious software attacks, and block the latter across your entire network and effectively ignore the former. Really it seems like you’re advertising your lack of imagination in this context than a legitimate lack of possible uses for spoofing open ports.




  • At a guess, you might tell the difference between some benign scan and an attempt to actually take advantage of the port, perhaps to use as a trigger to automatically ban an ip address? or a way to divert malicious resources to an easy looking target so they are less available in other areas?

    The difference between someone scanning for open ports and someone attacking a port they find open seems significant enough to at least track and watch for patterns… Whether that’s useful for the majority of users or not is rarely why a feature is implemented.




  • There is no way a US federal high speed rail would look anything nearly as successful as ones in europe or other highly populated locations. I think people fail to realize that for the most part the US is very sparsely populated. with the exception of maybe 2-3 ‘regions’ that might look close to the population density and public transportation feasibility of Europe, there just wouldn’t be enough people going between each individual point to make it profitable, even if subsidized. Imagine putting up 300 miles of high speed rail that cost many millions of dollars to build, millions of dollars a year to maintain, and thousands of dollars to run each round trip, and then finding out there are only a few dozen people that need to go between those particular terminals each hour. Trying to adjust by running less often just makes things worse because running less often means fewer people yet will find it convenient…running more often makes it less profitable…so you end up like the US and basically don’t bother making routes and stations without enough traffic.
