SQLite Begin Concurrent
Usually, SQLite allows at most one writer to proceed concurrently. The BEGIN CONCURRENT enhancement allows multiple writers to process write transactions simultanously if the database is in "wal" or "wal2" mode, although the system still serializes COMMIT commands.

When Will We See Collisions for SHA-1?
On a NIST-sponsored hash function mailing list, Jesse Walker (from Intel; also a member of the Skein team) did some back-of-the-envelope calculations to estimate how long it will be before we see a practical collision attack against SHA-1. I’m reprinting his analysis here, so it reaches a broader audience. According…

Message threading (1997-2002)
In this document, I describe what is, in my humble but correct opinion, the best known algorithm for threading messages (that is, grouping messages together in parent/child relationships based on which messages are replies to which others.) This is the threading algorithm that was used in Netscape Mail and News 2.0…

The Neural Net Tank Urban Legend
AI folklore tells a story about a neural network trained to detect tanks which instead learned to detect time of day; investigating, this probably never happened.

Linkers and Loaders (1999)
The text in these files is the unedited original manuscript. M-K has fine copy editors, who have fixed all the minor typos, spelling, and grammar errors in the printed book, but if you come across factual errors I'd still appreciate help getting all the details of linking and loading as complete and correct as…

Lisp inventor John McCarthy on human progress and its sustainability
The sustainability pages are essentially done, although I plan to improve them and respond to inadequacies people find. Having done my best to show that material progress is sustainable, I can justifiably turn my attention to the future and present ideas about what progress people will want and what can be achieved…

Notes on Programming in C – Rob Pike (1989)
What follows is a set of short essays that collectively encourage a philosophy of clarity in programming rather than giving hard rules. I don't expect you to agree with all of them, because they are opinion and opinions change with the times. But they've been accumulating in my head, if not on paper until now, for a…

Argentina on Two Steaks a Day(2006)
The classic beginner's mistake in Argentina is to neglect the first steak of the day. You will be tempted to just peck at it or even skip it altogether, rationalizing that you need to save yourself for the much larger steak later that night. But this is a false economy, like refusing to drink water in the early parts…

Fix Your Timestep
Introduction Hi, I’m Glenn Fiedler and welcome to Game Physics. In the previous article we discussed how to integrate the equations of motion using a numerical integrator. Integration sounds complicated, but it’s just a way to advance the your physics simulation forward by some small amount of time called “delta time”…

Feynman vs. The Abacus
A Japanese man came into the restaurant. I had seen him before, wandering around; he was trying to sell abacuses. He started to talk to the waiters, and challenged them: He said he could add numbers faster than any of them could do.

Locking in WebKit

Crit-bit Trees: the best way to store sets
A crit-bit tree can be used as a high-speed associative array. For example, an array mapping 54 to 1, 19 to 2, 99 to 3, 85 to 4, and 88 to 5 can be stored as a crit-bit tree containing 54=1, 19=2, 99=3, 85=4, and 88=5. The smallest string in the crit-bit tree larger than 85= is 85=4.

Version SAT
The package version selection problem is to find a set of dependencies that can be used to build a top-level package P that is complete (all dependencies satisfied) and compatible (no two incompatible packages are selected). There may be no such set, because of the diamond dependency problem: perhaps A needs B and C…
