APL is not so much a model of computation as a new notation for semantics which already exist. The real semantic explanation of APL is set theory and traditional mathematics. Probably the best deep ground-level explanation of APL is Iverson

Some of these aren’t bad. The Goal, for example, is a great book for helping you build intuition about constraints. But by far, the best manufacturing book I’ve read is Factory Physics, but Hopp and Spearman. It rewards study with a mathema

These do exist. They are used all the time for land-based oil rigs. Search for oilfield temporary roads.

That’s a bit reductive. For example, many anti-depressants affect serotonin reputake, which is now known to be integral to gut function. Further, often these off-label uses are at doses far below the levels required for anti-depressant effe

Buffet is well-known for this and I often hear tech people dismiss his views as a result, but I think some people misunderstand what he is saying. Buffet is concerned with companies that will have a long term competitive advantage and there

I agree the future is hard to predict, but I don’t know about your claim the US engages in similar trickery. Economic statistics for the US with fully disclosed methodologies are readily available. US military spending in 2016 was 3.3% of G

I'll just offer a contrary anecdote. A few months ago, I had a catastrophic failure of my X260 failure (hard crash--would not power up) while on site for a client in a manufacturing facility on the south side of Chicago. I called suppo

I must admit to being a little nostalgic for the original's high-affordance user interface elements. The original appeared and felt like more like a tool than a world unto itself.

Natural is poorly defined and has been the subject of class action litigation in California (particularly "All Natural"). [1] It is not an FDA defined claim. [2] In general, only the specific claims defined by the FDA may be used

I second the recommendation of this book. I also read this year a historical novel that features Humboldt which provided an engrossing opportunity to experience his world in a different way. Also highly recommended. David Kehlmann, Measurin
