Rails is omakase (DHH)
There are lots of à la carte software environments in this world. Places where in order to eat, you must first carefully look over the menu of options to order exactly what you want. I want this for my ORM, I want that for my template language, and let's finish it off with this routing library. Of course, you're going…

Falling Into The Pit of Success
Eric Lippert notes the perils of programming in C++: I often think of C++ as my own personal Pit of Despair Programming Language. Unmanaged C++ makes it so easy to fall into traps. Think buffer overruns, memory leaks, double frees, mismatch between allocator and deallocator, using freed memory, umpteen dozen

nasal demons
Recognized shorthand on the Usenet group comp.std.c for any unexpected behavior of a C compiler on encountering an undefined construct. During a discussion on that group in early 1992, a regular remarked “ When the compiler encounters [a given undefined construct] it is legal for it to make demons fly out of your nose…

The CRAPL: An academic-strength open source license
Generally, academic software is stapled together on a tight deadline; an expert user has to coerce it into running; and it's not pretty code. Academic code is about "proof of concept." These rough edges make academics reluctant to release their software. But, that doesn't mean they shouldn't.

OFFSET is bad for skipping previous rows
OFFSET doesn’t deliver stable results and makes the query slow. Key-set pagination does neither.

Why Can’t Programmers... Program?
I was incredulous when I read this observation from Reginald Braithwaite: Like me, the author is having trouble with the fact that 199 out of 200 applicants for every programming job can’t write code at all. I repeat: they can’t write any code whatsoever. The author he’s

The Meaning of ‘Hack’
“ The word hack doesn't really have 69 different meanings”, according to MIT hacker Phil Agre. “ In fact, hack has only one meaning, an extremely subtle and profound one which defies articulation. Which connotation is implied by a given use of the word depends in similarly profound ways on the context. Similar remarks…

NPM & left-pad: Have We Forgotten How To Program?
Intro Okay developers, time to have a serious talk. As you are probably already aware, this week React, Babel, and a bunch of other high-profile packages on NPM broke. The reason they broke is rather astounding: A simple NPM package called left-pad that was a dependency of their code. left-pad, at the time of writing…

Object-Relational Mapping is the Vietnam of Computer Science
I had an opportunity to meet Ted Neward at TechEd this year. Ted, among other things, famously coined the phrase “Object-Relational mapping is the Vietnam of our industy” in late 2004. It’s a scary analogy, but an apt one. I’ve seen developers struggle for years with the

A case against syntax highlighting
Do you rely on syntax highlighting when developing software? If so, you may be shooting yourself in the foot. In this post, I will argue that syntax highlighting, while aesthetically seductive, moves focus from content to form, and discourages those who look at the code from trying to understand it.

Computed goto for efficient dispatch tables
Recently, while idly browsing through the source code of Python, I came upon an interesting comment in the bytecode VM implementation ( Python/ceval.c ) about using the computed gotos extension of GCC [1] . Driven by curiosity, I decided to code a simple example to evaluate the difference between using a computed goto…

Groupware Bad
This piece has gotten a lot of attention over the years. I have heard a lot of people saying that they had been "inspired" by it. I fear that what they meant was that they were inspired by the one pull-quote that people tend to quote from it, and ignored the rest. So if someone has linked you to this page, or if…
