The “-2000 lines of code” report

First of all I’m sorry I’ve been so absent. I’m working on something of my own and I hope I can make it stable and working properly so I can talk about it here.
Meanwhile I read a nice post and I’m reposting it here:

In early 1982, the Lisa software team was trying to buckle down for the big push to ship the software within the next six months. Some of the managers decided that it would be a good idea to track the progress of each individual engineer in terms of the amount of code that they wrote from week to week. They devised a form that each engineer was required to submit every Friday, which included a field for the number of lines of code that were written that week.
Bill Atkinson, the author of Quickdraw and the main user interface designer, who was by far the most important Lisa implementor, thought that lines of code was a silly measure of software productivity. He thought his goal was to write as small and fast a program as possible, and that the lines of code metric only encouraged writing sloppy, bloated, broken code.
He recently was working on optimizing Quickdraw’s region calculation machinery, and had completely rewritten the region engine using a simpler, more general algorithm which, after some tweaking, made region operations almost six times faster. As a by-product, the rewrite also saved around 2,000 lines of code.
He was just putting the finishing touches on the optimization when it was time to fill out the management form for the first time. When he got to the lines of code part, he thought about it for a second, and then wrote in the number: -2000.
I’m not sure how the managers reacted to that, but I do know that after a couple more weeks, they stopped asking Bill to fill out the form, and he gladly complied.

About “Who should learn programming”

As most of you already know, there’s a buzz about who should learn to program and who should not. I will say now that im in favor that everyone should, and I say this because as you learn to program you learn a set of techniques that will most definitely help you all of your life.

Most people who are discussing this matter are focusing on the question “Ok, I learned to program, now what do I do with it?”. My answer to this question is: “I don’t care!”. Read more of this post

Phases of development

Late last week I wondered: where do the software terms alpha and beta come from? And why don’t we ever use gamma? And why not theta or epsilon or sigma?

alpha character beta character

Alpha and Beta are the first two characters of the Greek alphabet. Presumably these characters were chosen because they refer to the first and second rounds of software testing, respectively.

But where did these terms originate? Read more of this post
