"We Say So" corporation

I used to watch a rather funny show on ABC TV named “Dinosaurs” about your typical Jurassic period nuclear family, with large dinosaurs having similar problems to modern day humans. It was quite funny. The father dinosaur worked for “We Say So” corporation. Should give you an idea of what they did, and how they did it. You didn’t have a choice. You had to do what they wanted.
The following is a bit of venting.

DDoS jujitsu, or using the DDoSers mass against them

We have been under a DDoS with spambots sending us a few messages per day. Something north of 100k messages per day. I am not concerned about our infrastructure, it was holding up fine. I was more concerned about components that we didn’t have control over, or had no part in designing or building.
This begged the question: is there nothing that one can do to defend against a DDoS (email spambot) attack? It turns out that you can defend against it

The configuration strikes back …

The bot attack continues for a third day. We are rejecting, on average, one email per second. At this rate, we will have rejected 31.5 million emails over the course of 1 year. I wonder if the attackers think that DDoS is a good thing, or something valid to do to other net-denizens. Sad.

Phase transitions

Usually start with a few small nucleation sites. Create enough of a net savings in energy, and entropy, and whammo, you are starting the rapid, highly nonlinear, often discontinuous traversal of the phase coordinate.
Of such things, revolutions are born within computing. It is happening with APUs, it has happened with dual core, and it appears more likely to be happening outside of HPC.
Update: R.L. Polk is not that far from us. Seems to have taken them a long time to do migration, and I am concerned that someone was not reporting everything, or analyzing it correctly.

So many (mis)interpretations

Often times, things we say or write about are taken slightly (or massively) out of context, repackaged, and written or spoken about in a different manner that subsumes the original context or intent. Even well meaning people do this. It is all part of the process of forming an opinion, specifically an interpretation of events or speech. One might construe a specific person wrote something they did not.
