On the subject of DDoS...

I suppose it's the theme for the day.  Another really cool discovery I made recently is the Digital Attack Map:

It pretty much speaks for itself.  I'll put a permanent link to this handy page in the Resources section.

Google rolls out Project Shield DDoS attack mitigation service

I noticed on Engadget the other day that Google has rolled out a new service named Project Shield which is aimed at small static websites targeted by DDoS attacks.  This is a pretty cool gesture for those who have something to say but may very well fall victim to attackers who want to silence them.  Take a look at the article for more info.

Duplicate output with Tee

Quite frequently I'll run across a previously unknown gem that keeps my head from getting too big.  It doesn't matter how long you've been doing this type of work, there are things that everyone can learn.  I had a situation the other day where I needed to direct the output from a process to both a file and std out.  Now there are several ways one can accomplish this, whether with named pipes or a bit of creative redirects.  I did a bit of research and found that there is a tool just for such an occasion - tee.

Think of a T-fitting used in plumbing and you get the idea.  By piping output to tee, you can still get the output via std out but also send it to a file.  It's a standard *nix command, so check out the man page for more info.
