You're doing it wrong: B-heap 10x faster than binary heap (2010)
Would you believe me, if I claimed that an algorithm which has been on the books as "optimal" for 46 years, which have been analyzed in excruciating detail by geniuses like Knuth and taught in all CS courses in the world, can be optimized to run ten times faster ?

A Million Digits of Pi in 9 Lines of JavaScript
"Big integers" have landed in Javascript, at least in Firefox and Chrome. One of my favorite things to do with high precision arithmetic is to calculate digits of π. From scratch, that is, using only addition, subtraction, multiplication, and division.

Popcount CPU instruction
Most CPU architectures in use today have an instruction called popcount , short for “population count”. Here’s what it does: it counts the number of set bits in a machine word. For example (assuming 8-bit words for simplicity), popcount(00100110) is 3 and popcount(01100000) is 2 .

Let the callers of your API control allocations
This is a post about performance. Most of the time when worrying about the performance of a piece of code the overwhelming advice should be (with apologies to Brendan Gregg) don’t worry about it, yet. However there is one area where I counsel developers to think about the performance implications of a design, and that…

Three Tribes of Programming (2017)
There's an old joke that computer science is a lie, because its not really about computers, and its not really a science. Funny joke. Everyone laughs, then someone says "Yeah but it sort of is about computers though, isn't it?". Feet shuffle awkwardly. Someone clears their throat and before you

Lezer
I keep coming across people who consider parser technology a forbidding, scary field of programming. This is nonsense—a small parser can be very, very simple , and provide a wholesome exercise in recursive thinking. At the same time, it is true that you can make parsing extremely complicated. Mostly, this tends to…

Shenanigans With Hash Tables
One reason to know how your data structures work is so that when your problem has unusual constraints you can tweak how they work to fit the problem better or work faster. In this article I’ll talk about four different fun tweaks to the concept of a hash table that I made in the process of using hash tables to…

Tree traversal without recursion: the tree as a state machine (2007)
I am currently working my way through Higher-Order Perl , a highly recommended tome on effective and practical use of functional programming techniques in Perl. As you’d expect from a book that spends a lot of time discussing such concepts as function composition and recursion, the subject of tree traversal makes a…
