The issue is that incremental computation is a non-trivial problem that cannot be solved on a language design level. There are some new interesting players in the field though, eg. https://github.com/feldera/feldera

Much more principled (and hence less of a foot-gun) way of handling conflicts is making them first class objects in the repository, like https://pijul.org does.

From my experience the issue really is, unfortunately, that it is impossible to tell if a particular detail is irrelevant until after you have analyzed and answered all of them. In other words, it all looks easy in hindsight only.

At least in case of the kitchen contractor, you can trust all the electrical equipment, plumbing etc. is going to be connected in such a way that disasters won't happen. And if it is not, at least you can sue the contractor. The proble

I am Polish and I was 15 in 1990 when the Berlin Wall fell. Lately I was thinking if it was only me or my fellow Poles remembering 90s as times of freedom and hope. Thanks for confirming it is much wider experience and memory.

Indeed. The organization changed in the passing years. My worry is that there is more will to just dissolve it instead of working on improving it.

This. It looks like it goes in cycles: after major catastrophic event subsequent generations that don't remember the catastrophe are willing to engage in another one (I think of WWI and WWII as one event). If the memory was stronger th

The question is: how do you define "national security" and "other strategic value"? At the end of the day both really mean economic interest. Especially in case of US. So if someone says "national security" is

The theory is that in both cases (ie. with and without tariffs) shipyards are going to die sooner or later. It is better for the society to let them die as soon as possible and direct efforts to things we are better at while taking advantag

Here on HN I will be downvoted to oblivion but well... let's be it: There is no other way for us mortals than to go back to cash... Or start using Bitcoin. Be your own bank. Vote with your money.

I am not sure you are arguing against my claims or not :) I am not arguing against surrogate keys in general . They are obviously very useful _internally_ to introduce a level of indirection. But if they are used _internally_ then it doesn

Any piece of information that can be used to retrieve something using this index has to be available "outside" your database - ie. to issue a query "give me piece of information identified by X" you have to know X first.

If you expose the identifier outside the database, it is no longer "internal".

Network protocol designers know better and by default embed protocol version number in message format spec. I guess you can assign 3-4 bits for identifier version number as well. And yes - for long living data dealing with compatibility iss

Preferably, you would design you APIs and services to be idempotent (ie. use PUT not POST etc.) Using idempotency identifier is the last resort in my book.
