Eventually, No Security Measures Will Help Your System

“When in doubt, use brute force.” – with scalable distributed power the rate per second is mostly limited by cost , or the size of your botnet. Sure a login rate limiter or IP whitelist will help but in some cases that’s impractical. If you are lucky enough that the attacker has an IDS-usable signature that covers you some of the time (Like the current WordPress one). But eventually the password you chose is going the lynchpin of your security system. How complex is yours?

OCZ Vertex 4 SSD on Fedora Linux Benchmark

I needed more space for something so I grabbed a 256GB Vertex 4 to replace a 128GB. Looks promising so far , write speed is much faster , almost 100MB/s over the 128GB . See OCZ Vertex 4 128GB

Funny thing you can do with Linux

So I got a new laptop, completely different company, different CPU, different everything. I pulled the hard drive out of the old one, put it in place of the one that came with the new one…. Boot up and it’s as if I didn’t change computers. No activation phone call, No re-installation, No migration, no restoring from backup. It just runs.

I didn’t even think about it, this is the third time I’ve done it.
