Is CSS Turing Complete? | Lara Schenck

This starts as a good bit of computer science nerdery, that kind of answers the question in the title:

Alone, CSS is not Turing complete. CSS plus HTML plus user input is Turing complete!

And so the takeaway here is bigger than just speculation about Turing completeness:

Given that CSS is a domain-specific language for styling user interface, this makes a lot of sense! CSS + HTML + Human = Turing complete.

At the end of that day, as CSS developers that is the language we really write. CSS is incomplete without HTML, and a styled interface is incomplete without a human to use it.

Hidden Heroines of Chaos: Ellen Fetter and Margaret Hamilton | Quanta Magazine

Before leading the software project that put men on the moon, Margaret Hamilton worked on the equations that led to chaos theory, followed by Mount Holyoke graduate, Ellen Fetter.

Norbert Wiener’s Human Use of Human Beings is more relevant than ever.

What would Wiener think of the current human use of human beings? He would be amazed by the power of computers and the internet. He would be happy that the early neural nets in which he played a role have spawned powerful deep-learning systems that exhibit the perceptual ability he demanded of them—although he might not be impressed that one of the most prominent examples of such computerized Gestalt is the ability to recognize photos of kittens on the World Wide Web.

This is the best explanation of quantum computing I’ve read. I mean, it’s not like I can judge its veracity, but I could actually understand it.

Ways to think about machine learning — Benedict Evans

This strikes me as a sensible way of thinking about machine learning: it’s like when we got relational databases—suddenly we could do more, quicker, and easier …but it doesn’t require us to treat the technology like it’s magic.

An important parallel here is that though relational databases had economy of scale effects, there were limited network or ‘winner takes all’ effects. The database being used by company A doesn’t get better if company B buys the same database software from the same vendor: Safeway’s database doesn’t get better if Caterpillar buys the same one. Much the same actually applies to machine learning: machine learning is all about data, but data is highly specific to particular applications. More handwriting data will make a handwriting recognizer better, and more gas turbine data will make a system that predicts failures in gas turbines better, but the one doesn’t help with the other. Data isn’t fungible.

Dynamicland

An interesting Xerox-PARC-like project dedicated to making a programmable platform out of paper and other physical objects.

A humane dynamic medium embraces the countless ways in which human beings use their minds and bodies, instead of cramming people into a tiny box of pixels.

Meet Walter Pitts, the Homeless Genius Who Revolutionized Artificial Intelligence

The fascinating story of logic, learning, and the origins of electronic computing. Russell, Shannon, Turing, Wiener, Von Neumann …they’re all in there, woven around the tragic figure of Walter Pitts.

It is a sad and beautiful world.

Thanks to their work, there was a moment in history when neuroscience, psychiatry, computer science, mathematical logic, and artificial intelligence were all one thing, following an idea first glimpsed by Leibniz—that man, machine, number, and mind all use information as a universal currency. What appeared on the surface to be very different ingredients of the world—hunks of metal, lumps of gray matter, scratches of ink on a page—were profoundly interchangeable.

Are You Living in a Simulation?

Always worth bearing in mind when some perspective is needed.

If it is possible that our future species will go on to create simulations of our civilisation forerunners (us), then it is far more likely that we are currently in such a simulation than not.
