A night away from Ceylon turned into dinner, a movie, a serious software audit, and a complete rewrite of the rules for building the operating system.

September 10 was a genuine night off.

No Ceylon work. No documentation. No architecture review. No testing. Nothing.

That was intentional.

I have been spending enough time buried in Ceylon lately that taking an entire evening and simply not touching it was probably overdue, so that is exactly what I did.

September 11 started out considerably less serious.

I grabbed McDonald's for dinner and went to see Coyote vs. Acme.

The easiest way I can describe it is as something in the general neighborhood of Who Framed Roger Rabbit and Space Jam, but without all of the bells and whistles.

It is a simpler movie than either of those, and that is not necessarily a bad thing.

There is plenty there for kids, while the parents get the nostalgia of seeing Wile E. Coyote, Acme, and the familiar Looney Tunes world given the live-action treatment again.

It is not trying to be some enormous effects-driven spectacle. It is just a fun family movie with enough familiarity to keep the adults entertained too.

My verdict: 3 out of 5 stars.

Good for the kids. Nostalgic for the parents. Worth seeing for what it is.

Then I came home and somehow the evening became considerably more serious.

We conducted a fairly extensive software audit of the current Ceylon codebase.

The point was not simply to ask whether Ceylon builds, boots, or passes tests. We went back through the actual engineering assumptions behind several parts of the system: shared-memory behavior, synchronization, ownership, unsafe code, restart behavior, performance concerns, and the places where proof-of-concept implementations eventually need to become production-quality implementations.

We found some issues.

That is not a bad result.

In fact, that is exactly what I wanted an audit to do.

The important thing is that we are finding these weaknesses now, while the system is still under active development and they can be corrected deliberately, rather than allowing questionable assumptions to become deeply embedded in the operating system.

The audit also forced us to take a harder look at the rules governing Ceylon development itself.

The result was a complete rewrite of the Ceylon software-development contract.

The new contract is much more rigorous about what "finished" actually means.

Code existing is not enough.

A test passing is not enough.

Even getting something working on the target is not, by itself, enough.

The new development rules put much more emphasis on complete specifications, architectural ownership, requirements traceability, testing, target evidence, documentation, gap analysis, independent review, and keeping a durable record of why engineering decisions were made.

The idea is straightforward:

As Ceylon gets larger, I do not want it slowly turning into a collection of local fixes, undocumented assumptions, and architectural compromises that nobody can explain six months later.

The architecture needs to remain intentional.

So September 10 was a night completely away from Ceylon.

September 11 was McDonald's, a Looney Tunes movie, and then several hours of finding problems in an operating system and rewriting the rules for how we build it.

Apparently that counts as balance around here.

I am also about halfway through another fairly substantial piece of Ceylon documentation.

That one is not ready to discuss yet.

There will be plenty to say about it when it is.
