The Living Thing / Notebooks : Javascript apps

https://livingthing.danmackinlay.name/javascript_apps.html

The Living Thing / Notebooks. On the creation and testing of apps based on Javascript and possibly HTML5. Covered elsewhere. It’s called the web. Except there is a wrinkle of interest to some of us -offline mode. Tech allows you to serve a web app even without connectivity. I don’t care enough about this to really understand the API. I just cargo culted enough bits to make it go. Seems to work. You can do a lot by just hosting a webpage somewhere, and even some things with an HTML. And their ilk work.

The Living Thing / Notebooks : Running a secure server

https://livingthing.danmackinlay.name/secure_servers.html

The Living Thing / Notebooks. Running a secure server. Or at least a. So many parts to this, and I care so little about any of them. Making sure you are not instantly p3ned. Http:/ www.codelitt.com/blog/my-first-10-minutes-on-a-server-primer-for-securing-ubuntu/. Nonetheless, a baseline important detail to use modern web services is SSL. A notoriously tedious process. This recently got easier and cheaper with Let’s Encrypt. And their client software letsencruptnosudo. Or the full-stack webserver caddy.

The Living Thing / Notebooks : Faking being on social media (and other internet automation.)

https://livingthing.danmackinlay.name/faking_being_on_social_media.html

The Living Thing / Notebooks. Faking being on social media (and other internet automation.). Many people express the opinion that I am on facebook a whole lot. I am not. I am only ever on facebook for the mercenary reason that I wish to persuade people to do things for me for free, which is infrequent. And Twitter; Who has time for the twitters? People who manage your “engagement” with their “brand”, that’s who. But don’t worry, social media’s woefully dysfunctional. Has very hot AI. More gray-hat, you c...

The Living Thing / Notebooks : Message passing algorithms

https://livingthing.danmackinlay.name/message_passing.html

The Living Thing / Notebooks. I see these popping up in graphical model. Inference, in time-series, and in variational approximation. The grandparent idea seems to be Belief propagation , a.k.a. sum-product message-passing , credited to (Pearl, 1982) for DAGs and then generalised to MRFs, PGMs, factor graphs. Etc Although I gather from passing reference that many popoular algorithms also happen to be message-passing-type ones. Anyway, what the hell are these things? Minimizes α-divergence, (D alpha(p q) ).

The Living Thing / Notebooks : Automatic differentiation

https://livingthing.danmackinlay.name/autodiff.html

The Living Thing / Notebooks. Getting your computer to tell you the gradient of a function, without resorting to finite difference approximation. There seems to be a lot of stuff to know here infinitesimal/Taylor series formulations and computational complexity. Reverse-mode (backprop) versus forward mode, computational graph computation etc. There is a beautiful explanation of the basics by Sanjeev Arora and Tengyu Ma. You might want to do this for optimisation. See also symbolic mathematical calculators.

The Living Thing / Notebooks : Supercollider

https://livingthing.danmackinlay.name/supercollider.html

The Living Thing / Notebooks. Link) is the collective noun describing two coupled programming languages oriented toward live interactive music. I used ‘em a lot, e.g. for pattern machine. The default user-facing language is called. An aging smalltalk derivative with nice scheduling facilities. The DSP. The two talk to one another over a decrepit but servicable defunded network protocol from 1999 called opensoundcontrol. Perhaps you’d like to use javascript to control supercollider instead? Was released a...
