The editor is doing a final pass through it this summer, so the first print version will be ready for August. But, when I say August, it probably means September ;) The eBook version has been ready for a while now, and it gets constantly up

Speaking of short tutorials on linear algebra, you should check out this one I wrote last year. It's more of a "prepare for an exam" document, but it gets to the core idea of matrix-vector product serving as a way to "im

Wow this is an awesome online book. Goes into a lot of details, and uses words to convey the important things + supports it with code. Another good tutorial, more specific to OpenGL, is this one: http://www.songho.ca/opengl&

This is really long, but my sampling of 3 talks were all excellent. Here's a link to the Foundations of Data Science course that Michael Jordan discussed in his talk: http://data8.org/ [quote: [Statistics] is a 300 ye

Yes, LA is definitely worth relearning. I had a great time writing it since it was a chance for me to review a lot of material. Even more fun was writing about the numerous applications, in the end about 1/3 of the book is on applicati

Did you get the print version from amazon? Or a bookstore? I've found the amazon print-on-demand quality to be stuck in "economode" sometimes. I personally recommend people to purchase from lulu because the print quality ther

Wow, this is awesome! The Block-sphere "spy probe" is an amazing way to show what's going on with each qubit[1]. I wish I had this when I was teaching the intro to QM course! Suggestion: add some sort of menu for import/

All these years we had the buzzwords quantum and cloud separately. Today the buzzwords can finally merge to bring you quantum in the cloud . OMG, I predict the tech journalist will go crazy on this!! A very similar quantum circuit simu

So rather than actions/reducers being in separate files, they are part of one state-holder object? See like a useful simplification, but would be good if you can explain a little more what is the difference with usual react/redux

Why would you need to rollback? The new DB is not authoritative until the final step of the switchover, so you could easily scrap it at any point.

Learning quantum mechanics is not a big deal if you have a good background in linear algebra. I wrote a book on linear algebra that covers the basics of quantum mechanics as an application. No bullshit guide to linear algebra https:&#x2F

At my old job I had to do a major cleanup of a git repo with dozens of old branches. I got really good with the `git log` command. Here my alias form my ~/.gitconfig that shows author, branches, and remotes in a colorful manner:

Very interesting and promising. A related approach is to implant the islets in a "pocket" under the skin, which supposedly is easier to monitor and requires less immuno-suppressing drugs [1,2]. [1] http://www.nature.com

That's very cool. The API seems fairly similar to SymPy. It would be great to have a CAS that can perform simple operations in the browser, and ship more complicated things to a SymPy backend (or another CAS). http://live.sy

Fully agree. Your semantics of "expounder" and "expounded" spans is much more coherent. It's a new modality, but I think it has a lot of potential: I love explanations with "multiple levels" in general...

Oh yeah, I didn't know about this option. A static dir for /.well-known is a much more elegant solution than shutting down nginx... Thx for the pointer.

The --webroot option doesn't work for my setup, so I need to shutdown nginx for 2-3 seconds and use the --standalone option. I set this as a CRON job that will run every two months. It's not elegant, but it's done. Here'

Right. Also, I just saw that `letsencrypt-auto renew` will only issue new certs if < 30 days left on current cert.

Isn't running this as a `@daily` CRON job too much? I thought Let's Encrypt certs were good for 3 months? Why not @monthly or months 0,2,4,6,8,10 ?

Interesting idea. In the context of educational software, the "validation logic" would be the answer checking. The backend could do the checking in Python, but the same logic can also be shipped to the client as js for offline usa
