E.g. A depends on B. In a large update, B updates, something unrelated fails to install and the update fails, and now A doesn't run because it wasn't upgraded and the still installed old version of A depends on the no longer available previous version of B.
In NixOS, you either enter the new environment with all packages updated, or you don't. In the situation where you discover run-time - not install-time - errors, you can simply roll back to the previous set of packages. If the new packages cause a system crash, you can enter previous states from the bootloader.
Now none of this magically solves the software defects themselves. But it gives you a consistent system state that can be transactionally upgraded, or reentered at any time. And then you can raise the appropriate bug tickets.
Your system configuration is in a single file and the need to reconfigure different services in a particular order is gone.
Also your dependencies are all nicely pinned with Flakes. This makes importing arbitrary dependencies - open-source or proprietary - a breeze. This has removed any previous appetite we had for a monorepo, which was primarily to ease access to our other libraries.
It's all very nice, once you are over the not insubstantial learning curve that is.

It's even more interesting because an unknown IRL Chess.com player named Viih_Sou (since revealed to be Brandon Jacobson[2][3]) used this opening to defeat Daniel Naroditsky on May 2, 2024[4] only to be subsequently banned for violating the Fair Play Policy[5].

Why time seems to go by more quickly as we get older (2016)
My poor understanding is that React Native, and hence Expo, doesn't use the same CSS frameworks as web development. I'm curious how that works from the same code base, or perhaps that's one of the major difficulties.
Also I see Expo as a fancy build framework but it's still fundamentally a RN application. Is this correct?
(My front-end colleagues are on another continent and we don't get any water-cooler time. Sorry for the possibly awful questions.)
Feature request: historical tracking. E.g. on update, expire the old record with who & when.
On Nix either the install - and occasional build - succeeds and I enter the new environment, or it fails and I don't. In the worst case scenario where the build succeeds but something is funky I can just roll it back.
Now I have all this free time to lose to the time sink that is learning how to package applications in the Nix language.
I have just started The Book of the New Sun and am hopeful it will be a better experience.
While I enjoy the conversation ideas like these create, I'm often left wondering why Fischer random isn't more popular.
