This is a coding style where you add very gradually to a
file; a
statement or variable at a time, over the space of days
or
weeks. This can be before lunch, or after it; scattered
between meetings and visits to the loo. Refactoring is a
perpetual process; often you can have two or three
refactorings
happening at the same time, and sometimes
they may overlap.
Every time you revisit the file, you come in with a fresh
mind
and new ideas and a completely different perspective.
It is similar to peer review coding, in this fashion, and is
best
enjoyed with a pint.

This is a lifestyle without sprinting - why not just stroll. |
|

Refactoring is just a fancy way of labeling the failure to
realize that you should have thought of this before, and
now you're stuck with having the redo it. The best cure for
constant refactoring is to hire better programmers. |

I don't know where you work, [theircompetitor], but round here, nobody has any idea what customers are going to be asking for in ten years' time. |

check some of my ideas from ten years ago and you'll see
that
I don't suffer from that problem :) |

I was working on web services in 94, online trading in 97,
web conferencing in 99, mobile games in 2004 3 years
before the iPhone, and AR/VR in
2011. I'm safely ahead of anything my customers would
want. |

More to the point, Y2K was also "refactoring", but really, it's
easy enough to admit that even the Radio Shack TRS-80
could have handled a 4 digit year if people actually properly
thought about what they were doing. And my point was not
about all refactoring, but to the nature of the idea. Right
now around Wall St. they're trumpeting finally --
unbelievably -- going to 2 day settlement -- really
embarrassing given where technology is today. |

As an IT manager once said to me, at a major Wall St.
client, "you haven't invented anything I can't do with VSAM",
as he was fighting tooth and nail against any notion of a
"modern", at the time, database being used. As MongoDB
goes public today with a document model being a fancy way
of implementing keyed index files, you gotta wonder. |

I have never seen an IT shop -- and that would include
household name valley companies -- where there are not
plenty of
people that don't work as hard -- intellectually -- as they
should be. |

I suspect that the practitioner of this philosophy of coding will
find his novel
idea for an operating system on a disk to be a bit behind by
the time he finishes. |
|
| |
Maybe. But it's like painting a bridge. Start at one end, work your way to the other, then go back again. Try to avoid sanding, just build up layers. It's easier that way. |

Isn't this basically how government-funded IT projects work? |

My introduction to programming was while I was still under
the illusion that I will become an engineer (on Software
Engineering, read the above note about Refactoring). The
assignment was the calculate the value of the "e" constant in
Fortran. |
|
| |
I came home and said that I could not believe they pay people
to do this. |

My day job is QA for small manufacturing outfits - during this century it's been ruggedized computer equipment. |
|
| |
I used to study software QA as a hobby, these days my choice of entertainment is project management as a form of self defense. |

You guys are cracking me up. |
