Separating Programming Sheep from Non-Programming Goats
⚠ Please note, this paper was ultimately retracted by its author (pdf) in 2014: In 2006 I wrote an intemperate description of the results of an experiment carried out by Saeed Dehnadi. Many of the extravagant claims I made were insupportable, and I retract them. I continue to believe, however, that

the Lemacs/FSFmacs schism
In 1991, I was working at Lucid Inc., and our newest product, Energize, was an integrated development environment for C and C++ on Unix. The design of this development environment involved very tight integration between the various tools: compilers, linkers, debuggers, graphers, and editors. So of course we needed a…

Proebsting's Law
This means that while hardware computing horsepower increases at roughly 60%/year, compiler optimizations contribute only 4%. Basically, compiler optimization work makes only marginal contributions.

Netflix Update: Try This at Home
Ok, so here's where I tell all about how I (now we) got to be tied for third place on the netflix prize . And I don't mean a sordid tale of computing in the jungle, but rather the actual math and methods. So yes, after reading this post, you too should be able to rank in the top ten or so.

Wizards and warriors, part one
A common problem I see in object-oriented design is: A wizard is a kind of player. A warrior is a kind of player. A staff is a kind of weapon. A sword is a kind of weapon. A player has a weapon. Bu…

Parsing expressions by precedence climbing
I've written previously about the problem recursive descent parsers have with expressions, especially when the language has multiple levels of operator precedence.

sean cassidy : Don't Pipe to your Shell
It's everywhere . Sometimes they tell you to ignore certificates as well (looking at you, Salt). That's dumb.

bliki: Frequency Reduces Difficulty
"If it hurts - do it more often". Good advice if the amount of pain raises exponentially with the time between actions, such as for integrating software.

JSONPath - XPath for JSON
A frequently emphasized advantage of XML is the availability of plenty tools to analyse, transform and selectively extract data out of XML documents. XPath is one of these powerful tools.

Regular Expressions: Now You Have Two Problems
I love regular expressions. No, I’m not sure you understand: I really love regular expressions. You may find it a little odd that a hack who grew up using a language with the ain’t keyword would fall so head over heels in love with something as obtuse and

A performance comparison of Judy to hash tables
Numerous claims about Judy's performance are made in the Judy whitepaper . I don't think any of those claims are wrong. However, it does not appear that sufficient effort was put in benchmarking Judy against other data structures. Now, it is unlikely there is another data structure that is both as fast and as small as…

Raw Thought: Aaron Swartz's Weblog
As we’ve discussed, in Batman Begins 1960s-style full employment and antipoverty programs lead to skyrocketing crime while in The Dark Knight Rises 1980s-style tough-on-crime policies and neoliberal economics lead to a revolt of the economic underclass. The films are mirror images, one about the failure of liberal…

Basics of the Unix Philosophy
The ‘Unix philosophy’ originated with Ken Thompson's early meditations on how to design a small but capable operating system with a clean service interface. It grew as the Unix culture learned things about how to get maximum leverage out of Thompson's design. It absorbed lessons from many sources along the way.

How To Safely Generate A Random Number
Use urandom. That is the whole answer. Why the entropy-depletion story is a myth, and why userspace CSPRNGs are behind most of the last decade's randomness disasters.
