My Automobile Gets __ MPG

vogon jeltz Re:28-33 MPG (1141 comments)

My little padawan,

relax.

Most of your post is quite correct. But you've got something wrong about accelerating and decelerating up / downhills. Really wrong. Look it up at http://en.wikipedia.org/wiki/Potential_theory.

Then again, I'm a 'BM'-driver. Why do I feel kind of annoyed? My 120d does an average of 5.5l/100km, or 42mpg. Not all too shabby.

And yes, there *are* BMW-drivers that do respect the 'highway code', including me.

With the exception of course, that in Germany, I can legally go 140mph, and somtimes do :-)

2009, Year of the Linux Delusion

vogon jeltz Re:2001 was the year of linux - but no-one noticed (696 comments)

In this case, 1996 was the year of Linux. My department (Aerodynamics, TU-Darmstadt) ordered a DUAL Pentium 200 pro with a whopping 128MB of RAM (in order to replace the expensive SGI "Pizza boxes", aka SGI Indy). It outpaced the existing workstations by a factor of five, costing half. This is when commodity hardware started to do number crunching on Linux (preliminary Navier-Stokes stuff for the Airbus 3XX, now known as the Airbus 380). This was home-grown Fortran code, the kernel was 2.0.twentiiesh, and it already did SMP.
By the way, this was *my* year of Linux, I threw Windows 3.1 off my HD, installed (Debian)-Linux and never looked back. Ever.

What one thing would you take, if you had to leave the house for 24 hours and could only take one?

How to deal with ssh attacks?

vogon jeltz vogon jeltz writes  |  more than 5 years ago

vogon jeltz (257131) writes "My lowly server, with a dyndns account is under constant attack on port 22. I use it mainly for logging in from remote places in order to have, well, access to my server. There are no other services involved except ssh (no Apache, smtp etc.). While my passwords are safe, and I've hopefully never been breached (who could actually tell?), it bothers me to always having to look at 'tail -f /var/log/auth.log'. Is there a way to blacklist IPs which knock on port 22 or other recommendations? What do you guys actually do? For the record: I sometimes call the c-admins or tech-admins. Don't bother for regions like Asia, Africa, South America or even the US. In contrast, if I get somebody on the phone in Western Europe, they usually ask for the IP of the attacking computer and are actually thankfull for the information. Did you have similar experiences?"
