Possible path for organic zero calorie sugars!

Incorrect. There are symmetric achiral molecules. Which can be consumed as food for both normal, and mirror life, thus creating competition for resources.

What a shitshow of an article. The first victims of the Nova festival mentioned in this article are not the ones massacred, kidnapped and tortured by the gazans, it’s the ones killed by “Israeli police” in a “crossfire”.

For an article trying to celebrate peace love and unity in edm music, it fails to mention the fact that Hamas weee the ones to attack innocent festival goers.

But not all naive art comes from 3rd world. I remember learning about famous naive artists from Northern Europe which were quite amazing.

Back to 2015, I stopped posting on Facebook when I noticed that it’s no longer about connecting with my friends, but a never ending stream of boring posts from groups and people that I don’t know or care to follow.

All my “social” life just moved to direct communication in WhatsApp (meta owned as well)

Makes sense, thanks!

Thanks for the detailed comment! I always heard that bees pollinate the vast majority of plants, so in the parent comment, I assumed incorrectly that the meaning was for bees in general being non native.

If they are not native, how did plant propagate seeds? Flies? Wasps? Butterflies?

I actually find this incredible, since this highlights how desperate they are to advertise these glasses

Jest mocks allow developers to write bad code. Instead of separating concerns with DI, jest mocks overwrite the importing mechanism without any type safety. Also, if you wish to migrate to native node test runner, the mocks lock you into jest.

Use proper mocks with ts mockito and it will force you to write better code.

If you need to protect your border inside, than you already failed. Borders are protected outside the country.

Israel has clearly defined borders. If youre are talking about the West Bank there’s area a, b and c which are controlled by Israel, both, and PA respectively. I’d call that borders.

When all you need is a synchronous operations, yes. When it involves async, batching, buffering, and user input, it becomes much more complicated, and every step needs to be setup manually.

Agreed, the OP said that the r in rxjs stands for reactivity, so my point was the the names have little bearing on the actual design patterns achieved with the libs

A derived state is certainly reactive.

Maybe push pull wasn’t the best metaphor, but the point is that everything can be reactive, it only depends on how much boilerplate you need to write to achieve the desired result.

Since react doesn’t have a true reactive model, you need to subscribe to changes manually (use effect) to create computations, while in signals it’s a primitive (computed).

I actually created a lib that operates signals over reacts state management (https://roypeled.github.io/react-logic/), so I removed the boilerplate to create a true reactive system.

If you want, you can create reactive system just from JS primitives, using callbacks. But that doesn’t make JS reactive by nature.

Its entire state management is not reactive, it’s always on push, not pull. You always need to call setState to get render changes.

The react in react stands for reactivity, however it is not.

I partially agree, there is an overlap between signals and rxjs, however the core business is different- observables are about data manipulation, while signals are about efficient state management.

Regarding angular I agree, rxjs was a bad choice for data management, and before signals arrived I abandoned rxjs in favor of mobx in my angular projects. However you could roll your own http client, we used axios, and using DI it’s a drop in replacement.

Each one of these solves a different problem.

Promised - async

Observables - streams

Signals - reactivity
