I am hoping we have even more surprises in Rails World in two weeks time.

And may be a glimpse of ZJIT? It is not just Ruby and Rails has gotten faster, CPU performance and core count has been getting cheaper.

One thing I forgot to post last time in the GitHub CEO step down thread. I am hoping Microsoft won't force GitHub to move away from Ruby Rails. I remember there were some noise early on during the acquisition M$ wanted to get rid of it.

Re: GitHub.

IF they do a rewrite, that should buy us at least 5 years, based on my experience with large-scale rewrites lol

Even with AI?

In that case, it'll only take 8 years.

We need a new 80/20 rule. I propose a 90/0. You get 90% done quickly and the other 0% over the next few years .

We actually already have one of those, and it still fits just for a different reason:

> The first 90% is easy/fast/cheap, it's the second 90% that's hard/slow/expensive

Since most of the generative approaches treat code as disposable, then the second (and subsequent) 90% approaches just throw it away and start over. It's like all the awesome parts about a rewrite, with all the awesome parts about "it was rewritten because no one understood it"

I always heard it as "The first 90% of the work takes the first 90% of the time, the remaining 10% of the work takes the other 90% of the time." But yeah.

Ha! I've never heard of that one

Re: ZJIT: all development is happening in the open in the zjit folder of the ruby/ruby repo. You can follow along!

Having been on Microsoft acquisition before, generally they encourage .Net usage for greenfield if possible but it’s pretty gentle encouragement. I’ve heard they are getting pretty pushy against C++.

Really depends on the org you're in and what ecosystems you need to work with. Almost everything we write is Go based at Microsoft in my org.
