Official demos: github.com/KhronosGroup/glTF-Sample-Assets These are visible at: github.khronos.org/glTF-Sample-Viewer-Release/ with a JavaScript viewer present at: github.com/KhronosGroup/glTF-Sample-Viewer TODO can you load models on the web?
Supports animations, e.g.:
gltf-viewer.donmccurdy.com/ is based on doesn't work with those examples because they have separate asset files.
f3d just worked for it.

They appear to piece together data from various sources. This is the most complete historical domain -> IP database we have so far. They don't have hugely more data than viewdns.info, but many times do offer something new. It feels like the key difference is that their data goes further back in the critical time period a bit.
TODO do they have historical reverse IP? The fact that they don't seem to have it suggests that they are just making historical reverse IP requests to a third party via some API?
E.g. searching
thefilmcentre.com under historical data at securitytrails.com/domain/thefilmcentre.com/history/al gives the correct IP 62.22.60.55.Account creation blacklists common email providers such as gmail to force users to use a "corporate" email address. But using random domains like
ciro@cirosantilli.com works fine.Their data seems to date back to 2008 for our searches.
Wikipedia reads:so basically exactly what Ciro Santilli wants to do on OurBigBook.com. Ominous.
Any contributor could create and own new Knol articles, and there could be multiple articles on the same topic with each written by a different author.

Larry Page's father.
Carl is mentioned in The Google Story Chapter 2 "When Larry Met Sergey".
He divorced from Larry's mother Gloria in 1980 or 1981, "when he [Page] was eight years old" according to The Google Story. He then moved on to Joyce Wildenthal, another MSU professor. Larry had a good relation with both Gloria and Joyce:
Larry came to feel that he was showered with love and wisdom from two mothers: his real mom, and Joyce Wildenthal, a Michigan State professor who had a long-term relationship with his dad.
His obituary on the website of the Michigan State University, where he taught most of his life: www.cse.msu.edu/Alumni_Friends/Alumni/PageMemorial.php:
Page served as CSE’s [MSU Department of Computer Science and Engineering] first graduate director and had a critical role in promoting the department’s research mission. In 1967, when he joined MSU, the computer science program consisted of only undergraduate courses. Just three years later, the department offered eighteen graduate courses in computer science.[...]Page taught courses in Automata and Formal language theory and Artificial intelligence. He was a beloved teacher and mentor to innumerable students until his death in 1996.

The screenshot seems to be a Ctrl + P of some website, if only the author knew about Wayback Machine! The links on that screenshot would be of interest. The screenshot also mentions other family members:
- Carl B. Page, with a cpsr.org/ email. A brother maybe? www.legacy.com/us/obituaries/detroitnews/name/carl-page-obituary?pid=182235576%26utm_source%3Dfacebook%26utm_medium%3Dsocial%26utm_campaign%3Dobitsharebeta mentions a Carl B. Page from Michigan who died in 2010.
- Joyce Wildenthal, Carl's partner, with a pilot.msu.edu email. TODO what is
pilot?
She's truly passionate about health research and keeping healthy, almost obsessed by it. Also she's strong willed, and energetic. Good traits for founding 23andMe.

As www.nytimes.com/2017/11/18/style/anne-wojcicki-23andme-genetics.html puts it well:
The Wojcickis grew into Silicon Valley royalty. It’s the sort of family, Anne jokes, where “you’re only a viable fetus once you have your Ph.D.

An Introduction to Tensors and Group Theory for Physicists by Nadir Jeevanjee (2011) shows that this is a tensor that represents the volume of a parallelepiped.
It takes as input three vectors, and outputs one real number, the volume. And it is linear on each vector. This perfectly satisfied the definition of a tensor of order (3,0).
There is a Turing machine that halts for every member of the language with the answer yes, but does not necessarily halt for non-members.
Pinned article: Introduction to the OurBigBook Project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.

- to OurBigBook.com to get awesome multi-user features like topics and likes
- as HTML files to a static website, which you can host yourself for free on many external providers like GitHub Pages, and remain in full control
