I have bee trying to do a close button using CSS in order to close a tag. I have done this using a compination of a pattern described here: Patterns for Closebuttons, and a css only pattern for creating an X Close Button using CSS.

Now to my question: I can't figure out why the X is not entierly centered. If I change the placement to 50% of whatever width I'm using for the lines it seemes fine, thus I come to the conclusion it has to have something to do with the width of the lines.

I'm writing here to see if someone could explain this to me.

I'm trying to install Vuetify on Windows but I was getting permission errors, so I ran a new terminal as an Admin. With this new terminal I got a new permission error after selecting the "Default" preset:

I've installed GTTS using pip with python and the first copule of iterations seemes fine. However now I keep getting this error:

gtts.tts.gTTSError: 429 (Too Many Requests) from TTS API. Probable cause: Unknown

I've removed it from a loop but it stil wont run, here is my code:

This is my code: and it seemes that it doesn't work

Consider we have some system's module (M) and event emitter (E) which provides some updates required by M. When M subscribes to E it passes callback function (F) to E. At that point E would have reference to F and F would have reference to M (E → F → M). It means that M cannot be garbage collected because of event emitter. But conceptually, when M becomes unreferenced from across the system, it does not require any updates from E, so E should not prevent it from being garbage collected.

In today's JavaScript subscription model it is solved by returning explicit disposer (DF) which is a function that do unsubscription for that particular subscription. But I think that's bad for two reasons. First, it breaks natural rule of JavaScript: when something is not accessible by references that thing becomes garbage collected. Second, disposer is an additional reference. So, now DF references E, so not only E prevents M from gc, but vice versa as well (M → DF → E and E → F → M).

It seemes that this is a good place to use weak references. However, I cannot figuire out how to build event emitter on top of WeakMap or WeakSet. Even if you put subscriptions in weak container, you still need some hard references to take them out when you need to emit. This completely nullifies benefits of weak containers!

My best idea is a hypothetical «WeakSet which supports iteration». In addition to usual API: add, has and delete such object should have forEachWeak, which works just usual forEach and grants temporary owning over iterated objects. If user would not extract such objects into other hard ref container (like Array) this does not break weakness of references and still allow to iterate over. In case of event emitter, such emitter would have an ability to emit updates to subsctiptions without having them permanently referenced.

So, is it possible to build non-owning event emitter in this or any other manner?

With "observeOn(Scheduler)", Rxjava observable seemes that somtimes miss some items when the items are emitted from different threads.

Here is the code

I'd like the MPI function MPI_Sendrecv() to run on the GPU. Normally I use something like:

I am trying to combine two observables using forkJoin or combineLatest (my two options until now). One observable is from the ActivatedRoute's data (Observable) and one is a call to the API (Observable).

Initially these two were cascaded and everything worked fine. But I was thinking that this might be improved combining the two observables. I know that the observable from the activated route is not completed and it will be triggered every time the user navigates through the app. The second observable is completed when the response is received. The forkJoin works on the second type of observables (the ones that are completed) and combineLatest works with the ones that are not completed, taking their latest values.

Is there a way to combine these two or is the cascading approach the best way? Thank you!

EDIT: I've updated the code to fix some small issues and add the array deconstruction.

However, I found that when I refresh the app on the current page the routeData is an empty object, but if I add a breakpoint (in the DevTools tab Source) where the routeData is set it works. Or if I navigate to the component that sets the route data it still works. So I guess a small delay will enable the current routeData to be populated? But why isn't it triggered again when the actual data is placed on the route? I hope this is not too confusing

Later edit: I have 2 pages with their respective components: Asset Management (AssetManagementComponent) and Projects Management (ProjectManagementComponent). Project component is a child of Asset component. When the asset component is initialised I get some data from the API and place it on the route.data. Now, when the project component (child) is loaded, I want to get that route data and some extra specific project related data from the API.

The problem is that if I refresh the Project Management page, the code above will result in routeData being just an empty object {}. But if I go to Asset Management, then to Project Management, routeData will contain the correct data.

I've tried to debug this issue using DevTools and if I place breakpoints in each ngOnInit() function it will have the correct routeData, even if I directly refresh the app on ProjectManagement

UPDATE:

This is the final and working version: Adding the filter on the route data observable fixed it, it seemes that it triggered once with an empty object and later on with a valid object.

Thank you to everyone for your comments, I've learned new stuff and good practices! Have a great day!
