  • I used awk to migrate users from one system to another. I created template scripts for setting up the user in the new system, I dumped the data from the old system, then used awk to process the dump and create scripts for each user in the new system. That was a fun project.



  • Yeah, I’m sorry to say that is a result of good marketing. I work at a university and we have experience with a good number of XPS laptops.

    We saw at least a 60% problem rate, and Dell’s support was dog slow. Batteries being the weak spot. Because it’s thin it is more fragile, we saw a number of broken screens, and keyboards. One survived a Gatorade spill, but another failed after a water spill. Go figure

    A three year warranty helped, but we were out of a laptop for months at a time, more than once on the same laptop.




  • Geez really? I had no idea that pedestrians were so careless, what is it about larger trucks that makes people jump out in front of them.

    I like to see things as an opportunity, and I think we can use this as a lesson to do things differently. Like, let’s make trucks louder so you hear them before you see them. More Turbo, and how about vertical tail pipe stack. Next we can increase the number of lights, and make them brighter so that everyone can see. Let’s add more cameras and computers so the driver can see their blind spots simply by looking at the command console screen. We can even make these features available for free for a small amount of non invasive advertising.

    Do you remember how trains solved the problems of cows derailing trains. They put a guard on the front. So let’s make an even bigger steel bumper.



  • Yes that’s the right way to block root login. An added filter you can use the ‘match’ config expression to filter logins even further.

    If you’re on the open network, your connection will be heavily hit with login attempts. That is normal. But using another service like Fail2Ban will stop repeated hits to your host.

    Ssh listens on port 22, as soon as a connection is made the host moves the connection to another port to free up 22 for other new connections. Btw: I wasn’t thinking clearly here. Out going connections won’t be using port 22, but the listening incoming port is always 22.
