### Machine learning/statistics

- IPAM video lectures
- Graphical models: Decently paced lecture notes on Bayesian networks.
- Tutorial on Bayesian programming: An interesting experiment for an interactive book. The book is a set of iPython notebooks, so you can run the code as you read. The source is on github, so you can modify it as you go along.

### Computer science

- SCIP lectures
- Common LISP: a gentle introduction to symbolic computation – an easy to read text, mainly on the concepts behind LISP
- The algorithm design manual – a meaty text that is fun to read because it poses interesting problems and then goes into different ways of solving them – the problems are tough and it is fun to see how solutions to them, starting simply, can be approached.
- Jeff Erickson’s algorithm lecture notes

### Sites I find interesting

- Euclidea: Fun interactive geometry puzzles
- https://lobste.rs/ : The place where I go to for interesting articles on programming and tech.
- Bill Hammack (The Engineer Guy) creates informative and humorous short video demonstrations on EVERYTHING.
- Ask a mathematician/Ask a physicist
- I can’t tell you what Hackery is about, but it’s good.
- A real mathematician and programmer
- Lost in recursion
- A good old fashioned hardware hacker.
- Purely in-browser games
- Red Blob Games – learn computer science concepts through games, I mean, interactive demos.
- The online encyclopedia of integer sequences.

### Articles/items that I found fascinating

- Multi-dimensional analog literals in C++: I don’t actually know what this is doing, but it is an example of template meta-programming in C++.
- The mandelwat set – An extremely engaging, step-by-step tutorial on HTML canvas drawing and animation (lobste.rs)
- An introduction of microarray data analysis – Has a very compact and pragmatic introduction to microarrays. If you are getting started with microarray data analysis, this is a pretty good reference.
- NCBI Geo – In the context of microarrays – a lot of publications upload their data to this public repository. You can search for the data by accession number or by publication/author name, etc, just as you would a paper.
- Modern Garbage Collection – a nice primer on modern GC. (lobste.rs)
- Spikey spheres – and interesting take on the curse of dimensionality and properties of higher dimensional spaces (lobste.rs)
- A nice writeup (from ye olde times) about how to handle lag in gaming over a network. The author worked on the game Descent, which was a pioneering game because it was truly 3D and I spent many an hour in the lab playing this with buddies over a primitive LAN. (lobste.rs)
- Modular arithmetic – a nice note including modular arithmetic, Barrett reduction and division (2WF15 – Discrete Mathematics 2 – Part 1 Algorithmic Number Theory by Benne de Weger)
- Who Needs GPS? The Forgotten Story of Etak’s Amazing 1985 Car Navigation System.
- Four column ASCII
- Historical tax rates in real (2013) dollars
- P != NP – A nice writeup by Scott Aaronson
- Machine Learning best practices – from Martin Zinkevich of Google
- “A unified theory of garbage collection”, Bacon, Chen, Rajan (pdf) an easy to read paper with useful schematics of automatic memory management. Via this thread on lobsters.
- Reservoir sampling – an algorithm to pick a single random sample from a stream of unknown length
- A very engaging article on the discovery and re-discovery of the cause of Scurvy.
- A nice tutorial on Kalman filters.
- A simple generative function for Fibonacci numbers.
`(4 << n*(3+n)) // ((4 << 2*n) - (2 << n) - 1) & ((2 << n) - 1)`

- “Graphical algebra” interesting algebraic/trigonometric concepts lovingly described using animations of graphs. From the author of acko.net
- A painstakingly well done, interactive, visual introduction to machine learning.
- A extraordinary exposition of visualizing dimensionality reduction.
- Analysis of a raytracer written to fit on the back of a business card (almost).
- A nice article on camera shutters.
- Prime number spirals.
- A bezier clock.
- The xkcd pixels comic.
- A visual exposition of markov chains.
- Add up the sine waves. Fun interactive fourier explorer.
- An entertaining account by Tom Mahood, of his work with James Woodward, testing an inertial drive.
- A very good article on how malloc and co work to allocate/deallocate memory
- “We can’t send email more than 520 miles” – an epic debugging tale
- Repairing an underground high voltage power line
- A “magic carpet” ride to a suspended high voltage line
- Angels-on-a-Pin, AKA a tale of academic sabotage in the best of traditions
- The statistical analysis of fMRI data. Martin A. Lindquist, Statist. Sci. Volume 23, Number 4 (2008), 439-464 – A thorough but easy to read introduction to fMRI. Though the focus is on statistical methods, it has a great introduction to fMRI and some important tradeoffs that are characteristic of fMRI studies.
- Fifty psychological and psychiatric terms to avoid. I agree with most of them, though a few are acceptable simplifications for non-specialist writing
- The black box that pumps out primes. (And a related paper about a simple prime number generating formula)
