QUESTION
Say I have an xts object and return the index via an Rcpp function. Touching the xts object in this way seems to corrupt the xts object.
It can be fixed by forcing a deep copy.
While i do have a work-around, i don't understand why the problem exists -- or why my hack is required?
Using the suggested code from dirk's Rcpp Gallery, the xts object is corrupted once touched.

QUESTION
I have been trying to upgrade a typescript monorepo to make use of yarn 2 but am running into an issue where typescript is no longer able to determine certain react props. Since this was working in yarn 1.x, I am thinking there must have been some implicit dependencies being added in yarn 1.x that have to be explicitly defined in yarn 2.x? After hours of looking at project dependencies and node_modules I couldn't determine what needed to change in the production repo and so I created a sample project to reproduce the issue. Hopefully someone is able to point out what I'm missing.

Answered 2021-Apr-21 at 21:39It turns out that my yarn.lock file had been deleted and regenerated with a different @material-ui/types
version which was causing all my problems. It needed to be 5.1.0 and was instead 5.1.8
QUESTION
The documentation stresses that I should use a new EntityManager
for each request and there's even a middleware for automatically generating it or alternatively I can use em.fork()
. So far so good.
The EntityRepository
is a great way to make the code readable. I could not find anything in the documentation about how they relate to EntityManager
instances. The express-ts-example-app
example uses single instances of repositories and the RequestContext
middleware. This suggests that there is some under-the-hood magic that finds the correct EntityManager
instances at least with the RequestContext
. Is it really so?
Also, if I fork the EM manually can it still find the right one? Consider the following example:
...ANSWER
Answered 2021-Mar-25 at 11:14First of all, repository is just a thin layer on top of EM (an extension point if you want), that bares the entity name so you don't have to pass it to the first parameter of EM method (e.g. em.find(Ent, ...)
vs repo.find(...)
.
Then the contexts - you need a dedicated context for each request, so it has its own identity map. If you use RequestContext
helper, the context is created and saved via domain
API. Thanks to this, all the methods that are executed inside the domain handler will use the right instance automatically - this happens in the em.getContext()
method, that first checks the RequestContext
helper.
https://mikro-orm.io/docs/identity-map/#requestcontext-helper-for-di-containers
Check the tests for better understanding of how it works:
https://github.com/mikro-orm/mikro-orm/blob/master/tests/RequestContext.test.ts
So if you use repositories, with RequestContext
helper it will work just fine as the singleton repository instance will use the singleton EM instance that will then use the right request based instance via em.getContext()
where approapriate.
But if you use manual forking instead, you are responsible use the right repository instance - each EM fork will have its own one. So in this case you can't use a singleton, you need to do forkedEm.getRepository(Ent)
.
Btw alternatively you can also use AsyncLocalStorage
which is faster (and not deprecated), if you are on node 12+. The RequestContext
helper implementation will use ALS in v5, as node 12+ will be requried.
https://mikro-orm.io/docs/async-local-storage
Another thing you could do is to use the RequestContext
helper manually instead of via middlewares - something like the following:
QUESTION
All,
I have some problem setting up end-2-end transaction monitoring in ApplicationInsights, it seems to break the end-2-end view on my ServiceFabric ApiGateway service (.net CORE). This results in 2 traces in AppInsights instead of 1 (which I want ;-).
Ok my setup:
So an external API (.net core) which communicates to a ApiGateway (.net core stateless service) in a SF cluster via HTTP. Within the SF cluster all service (stateless full .net) communication is via Remoting V2.
I setup ApplicationInsights using ex. : https://github.com/yantang-msft/service-fabric-application-insights-example
In ApplicationInsights I see 2 traces (which should be one), being:
- a trace containing External API & ApiGateWay and the request to the stateless service
- a trace containing communication between the stateless services (which are multiple)
It looks like the "Operation Id" is not reused when sending the message from the APIGateway down. Is AppInsights i can see the "Operation Id" differ.
Does anyone have a idea? An I missing something? Should I set the operation id on the outgoing request in the ApiGateway (and how can I do that ;-))
...ANSWER
Answered 2021-Feb-05 at 09:17After some contact (https://github.com/microsoft/ApplicationInsights-ServiceFabric/issues/115) the issue became clear.
It's because of the new version of AppInsight is using a new protocol, which is in the .net version of the library. You can force AppInsights to use the "old" protocol and then the end to end trace works again. You can to this by setting the ActivityIDformat property to legacy one like below. (somewhere in app startup)
QUESTION
I'm trying to inject the FormBuilder service to a dynamic component this way:
Template:
...ANSWER
Answered 2020-Oct-21 at 11:22The ?
sign in errors like Can't resolve all parameters for class_1: (?)
means that Angular can't resolve type of parameter passed to constructor. In other words, reflector can't recognize that private fb: FormBuilder
parameter has FormBuilder
type because type dissappers after TypeScript compilation.
In order to tell TS compiler that it should keep this type you need to rewrite this class definition to version with decorator like:
QUESTION
Task at hand:
What I've taken a lot at so far:
- Pie chart from [https://github.com/JesperLekland/react-native-svg-charts-examples][2]
Here I divided the entire pie into 50 units of 1 value, inorder to get the Split-bar effect. I can pass the color according to the image shown above. But how can I add the inner lines(red and green) and the data inside? Any help would be appreciated!
...ANSWER
Answered 2020-Sep-09 at 10:46So the approach I would take is to make the outer ring a PieChart
(like you have done), but to make the inner circle a ProgressCircle
(https://github.com/JesperLekland/react-native-svg-charts#progresscircle) as this component naturally looks like the inner circle in the picture. You can change its backgroundColor
prop to red and its progressColor
prop to green.

I am trying to have a look at custom elements and how they work and while the examples on MDN work fine I'm seemingly unable to replicate them myself.
The MDN article is here.
This is a working example from MDN.
My problem is that I can't ever seem to pass attributes into my component, they always come out as null instead of passing over the value of the parameter.
My JS is (test.js)

Answered 2020-Aug-24 at 16:18You're missing a defer attribute in your script import within the HTML and it is not loading properly, thats the problem. The defer attribute allows the script to be executed after the page is parsed

I am using high charts in angular 8.I am getting chart for single object in an array of objects but i want to get each chart for each object dynamically how to achieve that. Below I have attached my working stackblitz for reference.
JSON:
...ANSWER
Answered 2020-Aug-17 at 08:30You could create a simple component that will take a chart's data as it's Input
and return standalone chart. Then you might use the *ngFor
directive to generate that component for each element of your data.
Unfortunately, I am not familiar with the angular-highcharts
, so I created the simple demo with highcharts-angular
- the officially supported Angular wrapper.

QUESTION
I'm trying to implement Stripe in my RoR app following the documentation. I've followed the steps up to '4 Save Card Details' where a form like this should display. However, when I click my 'Subscribe' button nothing happens.
The controller I'm using is called Subscriptions. When my submit button is in the subscriptions/show view the log error I get is ActiveRecord::RecordNotFound (Couldn't find Subscription with 'id'=StripeElements):
If I move it to the subscriptions/index view the log error I get is ActionController::RoutingError (No route matches [GET] "/StripeElements.css"):
I haven't modified my routes or controller because the documentation does not say this is required. The suggestions here and here haven't solved my issue.
I'm using Rails 5.2.4, Ruby 2.6 & Bootstrap 4.
show.html.erb
...ANSWER
Answered 2020-Apr-29 at 06:25Instead of following the Stripe documentation I followed this guide and had success.
