I’m sure you have seen something like this when you have connected to a ssh host.


The authenticity of host 'host (1.2.3.4)' can't be established.
RSA key fingerprint is 44:99:ff:33:66:88:cc:66:aa:22:00:00:ee:11:99:33.
Are you sure you want to continue connecting (yes/no)?


Great. Now what? What to do with that cryptic garbage up top? Log into the box or call the admin over the phone and verify the key.


$ ssh-keygen -l -f /etc/ssh/ssh_host_key.pub


No joke. Here’s a snippet out of an E15k manual.


Internal SRAM protection inside the UltraSPARC III Cu CPU. With higherdensity CPUs and lower-core voltages, SRAM cells have become more vulnerable to bit flips from cosmic-ray disturbances. Single-bit errors for the majority of the internal SRAMs are detected and are recoverable.


I’m sure it happens. I just find it funny that Sun has to design its chips to withstand interstellar high energy particles (or what-not). I’m no physicist.

Researching this Spring Framework. Most interesting so far is it’s touting of being modular. As in, you might only use it for a single feature and it wouldn’t be bloated.
