We are in such a situation, not for web but embedded and tools. We found getting the split between build system and CI right is one of the most important things. Don't model as CI dependencies what in essence is a build dependency. The

All these people that built GCC and evolved the language did not have the end result in their training set. They invented it. They extrapolated from earlier experiences and knowledge, LLMs only ever accidentally stumble into "between u

But this is about the first systems? I tend to tell people, the fourth try usually sticks. The first is too ambitious and ends in an unmaintainable pile around a good core idea. The second tries to "get everything right" and suff

Same. New ideas are like starting a fire. Piling too much on top or blowing too hard will stop it. You (together, however distributed across roles) do have to assess if you can handle one more fire, if it comes on top, replaces an old one e

Libraries differ in implementation and compilers have freedom to optimize floating point. William K was always furious that the kids don't get it (A nice The Tragically Hip song btw), his rants in his papers are actually entertaining t

Our graphs are hierarchical, can contain cycles, too and have a bunch of directed subgraphs. We reach 500 nodes with 20k ports and 10k edges and "getting the graph" is still possible but takes a bit of practice. Cycle breaking is

Had an original SE as banking backup. Recently the banking app demanded a newer iOS after being updated. Now that good old little device that was supposed to save me eventually is basically bricked for me.

The biggest improvement for us was deduplication by using generators an referencing already emitted objects. Don't run flatc on a JSON, it doesn't do that.

Testing is answering "does it do, what it is supposed to do?" and autonomous means "according to it's own law(s)". Sounds like a contradiction to me. I'd answer with "none".

Using this as well in embddded. The whole point is to commit and lock the pages after allocation, to not experience what you correctly describe. You want to have a single checkpoint after which you simply can stop worrying about oom.

The most important thing IMHO is to "rotate the structure 90 degrees" from package to function. You start with "all files of one package" and get "all files of all packages, that serve the same purpose" like fo

That is one problem of many solved, isn't that good? That the spec solves the problem is called validation in my domain and treated explicitly with different methods. We use formal validation to check for invariants, but also "it
