Received wisdom is that if you spend time up front getting the design right, you avoid costs later. But the longer you spend getting the design right, the more your upfront costs are, and the longer it takes for the software to start earning.
-
One of the advantages of having to live with JUnit for 8 years is now we can look back and see which decisions we made worked nicely and which we would have done differently.
-
We could talk, act, and dress funny. We were excused for socially inappropriate behavior: 'Oh, he's a programmer'. It was all because we knew this technology stuff that other people found completely mystifying.
-
First you learn the value of abstraction, then you learn the cost of abstraction, then you're ready to engineer.
-
Agitator and the Agitar Management Dashboard lower the barriers to accountability in software development and increase the value of developer testing.
-
I used Agitator on some code I had unit-tested, and it made me a better tester. As an Agitar Fellow, I look forward to the leverage of working with an outstanding organization as together we continue to improve the value of developer testing.
-
Often you'll see the same three or four data items together in lots of places: fields in a couple of classes, parameters in many method signatures. Bunches of data that hang around together really ought to be made into their own object.
-
Design should be easy in the sense that every step should be obviously and clearly identifiable. Simplify elements to make change simple so you can manage the technical risk.

-
People are looking for software development that actually does something useful... People are looking for partners who deliver when promised, and at a reasonable and transparent price. I believe that the days of being able to value price software are numbered.

If I'd had a charisma-ectomy in the beginning, XP would have gone nowhere.
-
There are musicians who want to make a living making music. There are listeners who want to listen to music.

My great-grandfather played organ for silent movies. Talkies in, Gramps out.
-
Whether you draw diagrams that generate code or you type at a browser, you are coding.
-
Developer testing is an important step towards accountability. It gives developers a way to demonstrate the quality of the software they produce.
-
Optimism is an occupational hazard of programming: feedback is the treatment.
-
There's a huge latent market for software development that's just flat-out honest.
