Gee wilickers

I have a common command-line pattern I grew tired of typing. An example

$ mvn verify | tee verify.out

I use this pattern so often as I want to both watch the build on screen, and have a save file to grep when something goes wrong. Sometimes I also find myself telling the computer:

$ mvn verify | tee verify.out
$ mv verify.out verify-old.out
$ $EDITOR pom.xml
$ mvn verify | tee verify.out
$ diff verify-old.out verify.out

I want to see what changed in my build. But ... too much typing! So I automated with gee, a mashup of

Basics of Web Application Security: Hash and Salt Your Users' Passwords

If you need to store your users' passwords, it's essential that you never store them plainly. Instead you must store a cryptographic hash of them, so that people who get access to your database don't get the passwords. Cade and Daniel explain how to do this properly: salting the hash to avoid lookup table attacks, and using an appropriate hashing algorithm to defend against well-equipped attackers.

Automating github

I got tired of downloading my own scripts from Github when working among multiple projects. So I automated it, of course. The bitsh project reuses a test script from the shell project, and now the Makefile for bitsh is simply:

SHELL=/bin/bash
test:
	@[ -t 1 ] && flags=-c ; \
	./test-bitsh.sh -i -- $$flags t

When run-tests is updated in Github, bitsh automatically picks up the changes. And I learned the value of ETag.

By the way, why "bitsh"? I hunted around for project names combining "git" and "bash" and found most of them already taken. Beggars can't…

Metaprogramming with Bash

Most programmers do not take full advantage of the languages they work in, though some languages make this a real challenge. Take metaprogramming, or programs that have some self-knowledge. LISP-family languages make this easy and natural; those with macros even more so. Bytecode languages (think Java), and even more so object code languages (think "C"), fall back on extra-linguistic magic such as AOP rewriting.

Text-based languages lay in a middle ground. Best known is Bash. Rarely do programmers take full advantage of Bash features, and few would think of metaprogramming. Not as clean as LISP macros, it…

The conversational event dude pairing (also known as the dual language pair speaking)

It is really nice to participate actively on a conference. Isn’t it? You know it is. You really enjoy taking part on great event sessions such as fishbowls, birds of feathers, open spaces, coach clinic and alike. The problem is when two languages are involved and not everyone speak both languages. Here is the scenario […]

Color your world

My coworkers use many ad hoc or single-purpose scripts, things like: checking system status, wrappers for build systems, launching services locally, etc. My UNIX background tells me, "keep it simple, avoid output; Silence is Golden."

Somehow my younger colleagues aren't impressed.

So to avoid acting my age I started sprinkling color into my scripts, and it worked. Feedback was uniformly positive. And true to my UNIX roots, I provided command line flags to disable color.

Some lessons for budding BASHers:

  1. Yes, experiment and learn, but be sure to do your research. The Internet has outstanding help for BASH.

Refactoring a javascript video store

The simple example of calculating and formatting a bill for a video store opened my refactoring book in 1999. If done in modern Javascript, there are several directions you could take the refactoring. I explore four here: refactoring to top level functions, to a nested function with a dispatcher, using classes, and transformation using an intermediate data structure.
