Reading short list
(Because I’ll find a book or article series that is important and then life will get in the way)
Sketch algorithms – (Or streaming algorithms) are probabilistic algorithms that can provide answers to certain questions about extremely large sets of data in a short time with known error characteristics. To compute such answers exactly would require a prohibitively large about of time and memory.
Deep learning – Relatively new techniques for training neural networks that have many layers/long credit assignment paths.
Graphical models: Decently paced lecture notes on Bayesian networks.
The long list
Machine learning/statistics
 IPAM video lectures
 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.
 Random projection. JohnsonLindenstrauss dimension reduction: If you project data to a lower dimension using a random projection matrix the pairwise distances will largely be conserved if the new dimensionality is of the order of the log of the number of points.
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
C++/low level programming details
 Undefined behavior in C/C++ – John Reghr [1] [2] [3]
 A survey of CPU caches (full pdf paper) – Cache lines, size, features, includes testing code.
 Cache Oblivious algorithms – “Cacheoblivious algorithms work by recursively dividing a problem’s dataset into smaller parts and then doing as much computations of each part as possible. Eventually subproblem dataset fits into cache, and we can do significant amount of computations on it without accessing memory”
 A guide to OpenMP – “OpenMP consists of a set of compiler #pragmas that control how the program works. The pragmas are designed so that even if the compiler does not support them, the program will still yield correct behavior, but without any parallelism.”
 Online C++ disassembler – write your code in the left hand pane. The assembly code appears in the right hand side. Magic!

 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.

 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)
