Dialogue: What do We Mean by Predictive Analytics?

Dialogue: What do We Mean by Predictive Analytics?

Predictive analytics is a phrase that gets used often as a feature in many tech offerings. Predicting when a problem is likely to occur allows either a human or an automated system to take some action to mitigate a potential issue before it occurs and has potentially catastrophic effects. If we take data storage, for…

Cayley’s Theorem: Powerful Permutations

Cayley’s Theorem: Powerful Permutations

We've discussed before how powerful isomorphisms can be, when we find them. Finding isomorphisms "from scratch" can be quite a challenge. Thankfully, Arthur Cayley proved one of the classic theorems of modern algebra that can help make our lives a bit easier. We'll explore this theorem and note the power of groups of permutations.  (more…)

Commentary: White Papers Don’t Impress Me Much

Commentary: White Papers Don’t Impress Me Much

I spent the last week at an event called Tech Field Day (my second time). In a nutshell, it's a traveling panel of 12-15 delegates who are generally IT professionals (and me) that visits 8-10 companies over three days to hear various presentations on their technology. Sometimes it's storage tech, sometimes networking, or cloud, or…

Isomorphisms: Making Mathematics More Convenient

Isomorphisms: Making Mathematics More Convenient

Much of pure mathematics exists to simplify our world, even if it means entering an abstract realm (or creating one) to do it. The isomorphism is one of the most powerful tools for discovering structural similarities (or that two groups are identical structurally) between two groups that on the surface look completely unrelated. In this post,…
