Why do We Care? Why Do You Care? I thought Concrete was rock, how does it fail so quickly? It’s mainly the rebar and “tension” based (rather than compression based) building techniques that require rebar in concrete. Rebar is steel and rusts. Especially when salt gets in, which it does over time from either road […]

Rome is a city that probably requires a little historical background to really appreciate. Probably good to watch a documentary or Youtube videos for anyone who doesn’t know much already. A short timeline, approximate:~700 BC – 250 BC – town grows to city. Not particularly remarkable in appearance250 BC – 50 BC – city of

“AI” models tend to be slow. This is generally inevitable to a large degree, lots of calculations to do means more time to run. Simply throwing more compute at the problem is one solution, but limits the ability to run models “at the edge” (ie on a phone) and raises the cost. Another solution is

Visiting the town of Lugo, which claims to have the most intact/unmodified set of Roman city walls (Muralla Lugo) surviving, I was struck by a picture I saw showing how the towers used to have arched upper levels that reminded me of the Porta Nigra in Trier. I thought that the towers would really have

In the world of forecasting there is a bit of mystery. Many expert forecasters continue to use statistical models despite the strong push of machine learning (ML) and deep learning neural network (NN) models. Those less familiar with the world of forecasting assume, because of the dominance of ML/NN models in computer vision and language

Background: as advanced algorithms become more common and useful, that’s “AI”, there is the constant background fear being discussed, of skynet and terminator style AI robots destroying all. The truth is less exciting: killer robots require lots of very expensive sensors and compute capability. Their programming tends to be much more brittle and slower to

The Coral Dev Board (2019), Dev Board Mini (2020) and Dev Board Micro (2023) are almost really awesome. They were really the first products to make running Edge AI operations feasible, the product of Google’s own development of products like it’s smart speakers and smartphones. On the positive side, Google hasn’t killed them yet like

I grew up on a diet of thick World War II history books, with a particular fascination with the technology of the war. Many things about it fascinated me, but it always felt a thing of the past. War happened in my childhood, on the other side of the world from me, mostly against small

There are some things humans need which don’t entirely make sense. Exercise is one example. It takes lots of energy to do exercise, so it seems counterintuitive that we would need what might be considered a waste of energy. Another example is sunlight. Sunlight is known to cause cancer, indeed we use it for sterilization

For a project I am working on, I would really like to have a semi portable, large tablet. As of my writing this, there’s one 14.7″ (37cm) tablet, the Samsung Ultra, then a handful of 13″ devices such as those from Apple. On Aliexpress and from LG I can also find touch screen more-like-a-TVs in
