Rob Pike: Notes on Programming in C
Rob Pike February 21, 1989 Introduction Kernighan and Plauger's The Elements of Programming Style was an important and rightly influential book. But sometimes I feel its concise rules were taken as a cookbook approach to good style instead of the succinct expression of a philosophy they were meant to be. If the book claims that variable names should be chosen meaningfully, doesn't it then follow
graydon2 | "What next?"
Warning: this has turned out to be a .. long post. Recently, on the twitters, Stephanie Hurlburt suggested that it'd be healthy for people who have been around the computering industry for a while (*cough cough*) to take some "audience questions" from strangers. I obliged, and someone asked me an interesting one: "After memory safety, what do you think is the next big step for compiled languages t
Cargo cult programming - Wikipedia
Cargo cult programming is a style of computer programming characterized by the ritual inclusion of code or program structures that serve no real purpose. Cargo cult programming is symptomatic of a programmer not understanding either a bug they were attempting to solve or the apparent solution (compare shotgun debugging, deep magic).[1] The term cargo cult programmer may apply when anyone inexperie
Parse, don’t validate
Historically, I’ve struggled to find a concise, simple way to explain what it means to practice type-driven design. Too often, when someone asks me “How did you come up with this approach?” I find I can’t give them a satisfying answer. I know it didn’t just come to me in a vision—I have an iterative design process that doesn’t require plucking the “right” approach out of thin air—yet I haven’t bee
Build a digital clock in Conway's Game of Life
Your task is to build a Game of Life simulation representing a digital clock, which satisfies the following properties: The clock displays the hours and minutes in decimal (e.g. 12:00, 3:59, 7:24) with a different state for each of the 1,440 minutes of the day — either the hours will go from 0 to 23 or from 1 to 12 with a PM indicator. The pattern is periodic, and the state loops around without an
「少人数のチームの方がソフトウェアの品質は高い」実証的ソフトウェア工学の研究会が開催
統計や実証を通してソフトウェア工学を研究していく、それが「エンピリカルソフトウェア工学」（Empirical Software Engineering、実証的ソフトウェア工学）です。「第一回エンピリカルソフトウェア工学研究会」が、12月10日に都内で開催されました。 基調講演では、マイクロソフトリサーチで研究をしているDr. Thomas Zimmermann氏が登壇。開発組織の構造がソフトウェアにどう影響するのか、バグ報告書やバグ報告者と修正されるバグの優先順位の関係、そしてエンピリカルソフトウェア工学という「データ指向のソフトウェア工学」を、どのようにソフトウェア開発における意志決定に役立ていくのか、といった内容の講演でした。 開発組織の構造がソフトウェア品質に及ぼす影響は？ マイクロソフトリサーチのDr. Thomas Zimmermann氏。 今日はいくつかのテーマについて紹介した
Experiments with Google
A note to our community Experiments with Google was born out of a simple idea, but you all turned it into something beyond anything we could have ever imagined. You filled it with thousands of experiments that inspired people everywhere - from the classroom to the surface of Mars. When it comes to the internet, 14 years is a long time. So in the spirit of experimentation we’re trying something new

自分が今、興味のあるプログラムを中心にプログラムの記事を書いていきます。 はてダ( http://d.hatena.ne.jp/nakamura001/ )などもやっているのでそちらで書いたものなどもこちらにまとめたりしようと思っています。
The Julia Programming Language
Fast Julia was designed for high performance. Julia programs automatically compile to efficient native code via LLVM, and support multiple platforms. Dynamic Julia is dynamically typed, feels like a scripting language, and has good support for interactive use, but can also optionally be separately compiled. Reproducible Reproducible environments make it possible to recreate the same Julia environm
How Do I Declare A Block in Objective-C?
As a local variable: returnType (^blockName)(parameterTypes) = ^returnType(parameters) {...}; As a property: @property (nonatomic, copy, nullability) returnType (^blockName)(parameterTypes); As a method parameter: - (void)someMethodThatTakesABlock:(returnType (^nullability)(parameterTypes))blockName;
Essential Math for Games Programmers
As the quality of games has improved, more attention has been given to all aspects of a game to increase the feeling of reality during gameplay and distinguish it from its competitors. Mathematics provides much of the groundwork for this improvement in realism. And a large part of this improvement is due to the addition of physical simulation. Creating such a simulation may appear to be a daunting
Bayesian Methods for Hackers
An intro to Bayesian methods and probabilistic programming from a computation/understanding-first, mathematics-second point of view. Prologue The Bayesian method is the natural approach to inference, yet it is hidden from readers behind chapters of slow, mathematical analysis. The typical text on Bayesian inference involves two to three chapters on probability theory, then enters what Bayesian inf
