Throwing away 18 months of code and starting over

It's not really hinted at in the article, which doesn't actually mention whether the rewrite was a net gain - I presume it was or they wouldn't have written the article, and the lead-in picture paints a rosy picture, but the tone at the end suggests he's not happy with how things turned out.

But one thing that used to be a common design anti-pattern was the "version 2 problem". I think I first heard about it when Netscape were talking about how NN2 was a disaster, and they were finally happy with NN3 or NN4.

Often version 1 is a hastily thrown together mess of stuff, but it works and people like it. But there's lots of bad design decisions and you reach a limit with how far you can continue pushing that bad design before it gets too brittle to change. So you start on version 2, a complete rewrite to fix all the problems and you end up with something that's "technically perfect" but so overengineered, it's slow and everybody hates it, plus there are probably lots of workflow hoops to jump through to get things approved that you end up not making any progress, and possibly version 2 kills the product and/or the company.

The idea is that the "version 3" is a pragmatic compromise - the worse design problems from version 1 are gone, but you forego all the unnecessary stuff that you added in version 2, and finally have a product that customers like again (assuming you can convince them to come back and try v3 out) and you can build into future versions.

To a large degree I think this "version 2 problem" was a by product of waterfall design, it's certainly been less common since agile development became popular in the early 2000s and tooling made large scale refactoring easier, but even so I remember working somewhere with a v1 that the customers were using and a v2 that was a 3-year rewrite going on in parallel. None of the developers wanted to work on v1 even though that's what brought in the revenue, and v2 didn't have any of the benefit of the bug fixes accumulated over the years to fix very specific issues that were never captured in any of the scope documents.

Having a culture of not ever writing tests and actively disallowing them is so insane I can't even imagine why there's anything else in this post

Pearls.

Tests are most useful for regression detection, so it's a good instinct to not add them when you're primarily exploring. Once you've decided to switch to exploitation, though, regression will hurt. I think it's just a classic 0 to 0.1 not being the same thing as 0.1 to 1.

I wouldn’t admit to this level of frankly incompetence.

Wildly swinging dogmatism on how to do software development that’s so wrong you have to throw it all away - then repeating this failure loop multiple times.

Doesn’t inspire any confidence in the person I wouldn’t get them to lead a project.

Why would you be so loud and proud about all this.

Next is such a dumpster fire. So much wasted effort due to the Node ecosystem never developing a universal batteries included framework like Rails or Django.
