#Signals
#BBC #UFOs : #Nasa's #UAP team mentioned a burst of #RadioWaves picked up by researchers in #Australia ๐ฆ๐บ.
"They had really strange structure. People couldn't figure out what was going on. Then they start to notice a lot of them bunched together around #lunch ๐ฝ๏ธ time"
It turned out that the sensitive instruments used by researchers were picking up #signals ๐ถ from a #microwave used to heat up their lunches. https://www.bbc.com/news/world-us-canada-65729356

I wrote about Angular Signals, a new feature coming with Angular v16. Enjoy.
More MOMA, this time some shots from the top floor "Signals"
show- a real mind melter. Im a Nam June Paik fan (loved seeing Zen for TV), but seeing these video pieces around media, "news", broadcasting and surveillance. If it didn't cost $25 per visit I would come back just to see the video show. Dara BirnBaum's intimate Tiananman square piece was well placed aside Julia Scher's Information America.

Back again at my #40YearsAgoSeries on #Insta . On the 11th of may in 1983 I was attending my third #RUSH concert. And it was fabulous as always with these guys. They are my favourite band and that will not change no matter what. In hindsight I think it was an odd choice to pair them with #Nazareth as an opening act, but at the time it might have seemed relateable for the promoter. #ProgressiveRock #Prog #Signals #Livemusic #Rock #Concert #Memories ๐ถ ๐ค๐ค๐ค๐ถ

Looking for a better way to manage state in your Angular applications?
The new Angular signals are well suited to effectively manage the data we retain in our components and services.
Check out the video here:
Angular Signal vs RxJS Behavior Subject. . . Fight!
Just kidding. ๐
In reality, there are use cases for both. In this video, we take a look at how to replace a synchronous BehaviorSubject with a signal.
Angular v16 RC 1 is out!
This release candidate includes some changes to RxJS/signals interop:
๐ฅ Renamed fromObservable/fromSignal
๐ฅ Changed how the fromObservable default works
๐ฅ Improved error handling
This video applies these changes in a sample app.
Lots of math coming up next week! Me and some folks from @OpenResearchIns are mucking around with how we represent and form the #signals we put on the air. We are poking hard at some widely accepted assumptions.
And, we've made some friends along the way :D
Looking to put together some #prototypes and show them off at first opportunity.

I'm making an ear training tool - https://earbetter.ryanatkn.com/ - source at https://github.com/ryanatkn/earbetter
feedback welcome, and I could use help designing the challenges, I'm not a musician
it's made with #svelte #SvelteKit #TypeScript and #preact #signals as the store library
I like the signals library a lot but it's a sharp tool that requires a bit more care than Svelte stores because its API is less explicit and more powerful. It's terse and fast and composes well. I'll keep using it to learn more.

#Signals are just the reactivity model from #Solid, #MobX, #Ember, #Knockout, et al. It pushes a notification with an #observable-like mechanism that something has changed, thereโs a dependency graph (implicit or explicit) that is notified. Then, it schedules a pull to calculate values. #ReactJS #Preact #javaScript #webDev #frontend
it's interesting that the most popular #react wrapper for an actual lisp (clojurescript) uses #signals in place of useState(). you'd think truly functional languages would try to avoid that piece of mutable state.
This is how I build apps now:
Standalone model(s) built with #Preact #Signals so they're implicitly reactive.
Components simply reference the model instance from context and access its (reactive) properties.
Testing the model without components is fast and easy. Testing the components a with mocked model is fast and easy.

@spierala @angular
I think people are already using async/await and promises with Angular in large numbers, and that these people are just not as vocal in social media and github as rxjs proponents. It is an illusion imho that all Angular codebases look the same because Angular is an โopinionatedโ framework.

Ok more Signals fever ๐
My friend @thomasreggi just told me to try deno fresh as it is a build free environment.
Interestingly version 1.1 offers jsx & preact signals out of the box and is a full stack web framework.
Now I will have to look into this.
@ro @robertvh I agree you are right, the concept of signal implementation does not require a compiler, however modern framework compilers improve developer experience via analysing if a parent component state is going to two children and which of them should be updated if only one is required to update.
I recently read an article that states this clearly which I will add it to an attached toot ๐๐ผ
I thought that the birdsite had lost all it's web nerds to the fediverse, but it seems that all the #ReactJS discourse is still happening there. Nobody here is talking about #Signals, but it's all they talk about there.
Mastodon is just for the web-edgelords, who have rejected the mainstream frameworks.
Scoped zone.js is not happening, it seems:

Why Signals are so cool in comparison to useState in React.

Luckily Signals will become part of Angular ๐
I wrote an NgModelSignal directive using signals from @angular v16-next and parts from
@synalxโs rxjs-interop PR:
https://stackblitz.com/edit/angular-ng-model-signal?file=src%2Fng-model-signal.directive.ts
Not sure about the part where I'm setting a signal in the updateEffect... According to Pawel Kozlowski this is not a good idea. Is there a better alternative?
After watching this video (#angular + #signals): https://www.youtube.com/watch?v=4FkFmn0LmLI
I have mixed feelings.
I guess that removing zonejs and removing some trivial rxjs usage (subjects) is good. One of the things I diskile more of angular+rxjs is the fact of having to unsubscribe, sometimes it is not easy, and you can create a mem leak.
Would porting the actual code to signals be painful or time consuming? I hope not :)
Going from untyped forms to typed (I work on a generic framework) was not trivial.
Here's the draft for the RxJS interop layer of @angular signals: https://github.com/angular/angular/pull/49154
You can create a signal from an observable using the function "fromObservable"; the signal value type is a discriminating union of "NoValueState", "ValueState<T>" and "ErrorState" (the property "kind" is the discriminant), which reflects the different states an observable can have. Interestingly enough there is no "CompletedState" (yet).
Quote from @dylhunn concerning potential benefits of signals in Angular:
"I'm particularly excited about our exploration of per-view change detection, which we expect to be possible with Signals! This will allow us to re-render at a sub-component level."
@brechtbilliet
looks like articles and books about change detection in Angular will have to be rewritten (or augmented ๐).
@sarah_edo has set up an Angular signals primer: https://angular-signals.netlify.app/ (in case you ask yourself what the fuss is all about ๐).
@sanderelias's analysis is more thorough: https://github.com/SanderElias/Samples/tree/1ce26dcea5d4e3f0c3d93295c6de146229a7d327/Angular-Signals
Interesting takeaways from @synalx's chat with @brandontroberts about signals in Angular (https://www.twitch.tv/videos/1740066149):
- Using signals as component Inputs eliminates the need for ngOnChanges.
- Signals are not limited to components; they can also be used in services!
It will probably be possible to experiment with signals in Angular 16 according to @synalx .
Also: in the future the compiler can optimize signal usage e.g. when signals are used for monitoring and manipulating the DOM; in this case the compiler would be able to streamline the read and write operations to avoid unnecessary reflows.
Big Quantum Biology Meetings
A major goal is to identify #biomedical problems that may be amenable for #quantum information/sensing applications for the measurement of highly sensitive and specific #biological and #cellular #signals in normal and diseased states.
In addition, we hope to illuminate use cases that can be optimized and developed further for wider adoption by the community through enabling development of easily accessible bench-top instrument and portable devices and wearables.
These goals will be accomplished through invited seminars, workshops from national and international experts in QIS/QSB, identifying opportunities for learning, training and workforce development for fellows and trainees in collaboration with academia, industry, and government agencies

"Ma and his colleagues sifted through #BreakthroughListen observations of 820 stars, made using the 100-metre Robert C. Byrd Green Bank #Telescope.

I'm really interested in #technology #transitions - and watching the #TwitterMigration to #Mastodon makes me think about how we know transitions are taking place and how far along we are in a transition or regime change.
Accounts like @mastodonmigration post useful stats on how many new users are joining the #Fediverse, often correlating with some sort of Twitter controversy.
But what other #indicators, #signals and #metrics inform our view of the adoption of the #Fediverse? Here's some I can think of:
๐ Font sets like Font Awesome provide #mastodรณn and other Fediverse-aligned logos, like #Pixelfed.
๐ Businesses begin to advertise their Mastodon address alongside other social properties.
๐ We start to see whole-of-government or whole-of-sector approaches to creating and maintaining Mastodon instances - for example, mastodon.gov.au.
๐ We start to see COTS offerings of Mastodon hosting by hosting providers
๐ We start to see Udemy and other micro-learning providers offering Mastodon "certification"
What other signals can you think of?
Ow my, I love #signals in #javascript (#preact)!!
Reminder: you can cast a Signal to unwrap its value without having to write `.value`.
Anyone familiar with #SolidJS #signals able to help me understand why they don't leak memory? Why don't you need to unsubscribe?
AFAICT, each signal in the graph contains a list of all its reverse dependencies (all signals who depend on it). This feels circular to me and I don't see how the browser could clean up those references.
Is a mark-and-sweep GC strategy able to handle this or am I missing an implicit unsubscribe somewhere?

@poebbel No....?
Is there such a function, or are you seeing this in what I've written?
(If the latter, then thank you, as that's ... possibly useful.)
Actually, I think what we'd be looking for might be something like:
Message: ฮดe/ฮดt * d
Record: ฮดm/ฮดd * t
(I'm pretty sure that's wrong. It's conceptually ... interesting)
That's the "change in energy with time ... multiplied by? ... space" and "change in matter over distance ... multiplied by? ... time".
I'm pretty confident of the differential bit. The operation and the third term, not so much.
There's quite a bit of physics of signals and wave propagation, and the message equations might borrow from that. Also Claude Shannon.
I'm not aware of a similar physics of records, per se, though some aspects of that, e.g., Newton's Laws of Motion, would apply.
#information #signals #records #InformationTheory #ReallyBadPhysics #ReallyBadMaths
@feonixrift I think I've ranted about the symmetry of signals and records before:
Signals encode semantic meaning via changes in time to transmit messages through a channel in space subject to noise to a reciever via energy changes without time pesistence.
Records encode semantic meaning via changes in space to transmit messages through a medium in time subject to deterioration to a reader using energy changes without spatial spread.
