QUESTION
I'm trying to use Fable.Reactstrap on Client project from SAFE.Template. I've added Fable.Reactstrap to Nuget, Paket, and NPM but still receive error FSHARP: The namespace 'Reactstrap' is not defined when executing dotnet run. It's an error from code:
ANSWER
Answered 2022-Feb-14 at 03:08The namespace is just Reactstrap, so this should work:
QUESTION
I calibrated a camera according to:
...ANSWER
Answered 2022-Feb-01 at 18:37Rt is just the transformation (rotation, translation) from world to camera frame.
You expected a projection?
If you want to project the point, you still need to apply the camera matrix (and then maybe the distortion coefficients to be precise, but let's not get into that).
QUESTION
I guess I have a simple problem, but I'm not able to solve it: I want to create a vector, call FFI on this vector and return it.
...ANSWER
Answered 2022-Jan-21 at 18:51For FFI applications, it's usually simplest not to bother with ST at all and do everything in IO. If you must have a pure interface (and your FFI function actually is pure in the way needed), you can call unsafePerformIO to give a pure interface.
However, I think I would shy away from writing withCarray as you have done here. Abstraction is nice, but this is too easy to accidentally misuse by passing a not-suitably-behaving callback. If you must have it, at the very least name it unsafeWithCarray and leave a Haddock explicitly stating under what circumstances it is safe.
QUESTION
I have a React frontend and a Node backend, I've made several E2E tests with Cypress for the frontend and run them locally. I love how end to end testing allows me to catch errors in the frontend as well as on the backend! so I'd like to have a way to run them automatically when sending a PR.
I'm using bitbucket pipelines, and I've configured it to run the npm test command which works perfectly to run my unit tests, but what I still don't understand is how to be able to run my Cypress tests automatically, because I'd need to have access to the backend repository from my pipeline that runs on the frontend repo.
What I've tried
I've read the documentation and played with the example repo, but I still don't understand how could I automate running my tests, on the example both backend and frontend are on the same repository.
I'm sorry if this is a vague question, I just don't seem to get if this is even possible with bitbucket pipelines, if it's not, what other tool could help me run my Cypress test in a similar way that I do locally? (running both backend and frontend).
I've really tried to search for an answer to this, maybe it's too obvious and I'm just missing something but I don't seem to find anything on the internet about this, any help will be very appreciated!
...ANSWER
Answered 2022-Jan-20 at 06:12When your frontend and backend are versioned in different repositories, then you have to check out at least one of the two repositories (e.g. the other for which the pipeline is not currently being executed) during the pipeline execution to get access to the code and thus have the possibility to start frontend and backend together locally to run your tests.

QUESTION
After 2 days of researching and trying different tutorials/approaches trying to grasp this issue, I've given up.
I have an explanation of what I am fully trying to achieved in this youtube video... https://youtu.be/GJ6Du0EENhc - 7min
This simplified problem: In my test scene I have a plane inside a container. There is also a sphere called "modelref" inside the container, positioned so it intersects the plane. Outside of the container is another sphere called 'realworldref'.
What i want to do, is press a button and the model ref will move to the location of the realworld ref. At the same time, it should drag verticies from the plane with it such that the vertices closest the the modelref are pulld all the way to the new location, with the effect disipating out to the radius 'influence area' (ultimately to be defined by a box collider).
What I've tried: I've made some simple steps (omitting the influence radius), but my brain is failing to grasp directions, vectors, magnitudes etc... so the vertices of the plane aren't even moving the right distance in the right direction.
Here is my current script which is on the modelref:
...ANSWER
Answered 2021-Dec-23 at 15:26The direction is in world space, so if you want to move vertices along it, you should transform it into model space first.
QUESTION
This following code actualy works, but I wonder if it's a good practice or not. Because to me, it sounds like I breaking the rules. But I dont see other ways to do what I want. And I want to render 2 lists build with the same logic but that render different types of items. If you know a better way to do this tell me how.
...ANSWER
Answered 2021-Nov-25 at 08:36Looks like its fine if BlueItem and RedItem both have specific attributes and difficult to handle out of the component. See below example of React Router
QUESTION
I am using nsidnev/fastapi-realworld-example-app.
I need to apply transaction logic to this project.
In one API, I am calling a lot of methods from repositories and doing updating, inserting and deleting operations in many tables. If there is an exception in any of these operations, how can I roll back changes? (Or if everything is correct then commit.)
...ANSWER
Answered 2021-Nov-20 at 02:01nsidnev/fastapi-realworld-example-app is using asyncpg.
There are two ways to use Transactions.

QUESTION
I have a basic knowledge of kafka topic/producer/consumer and broker.
I would like to understand how this works in realworld.
For example Consider below usecase .
- User interacts with Web application
- when user clicks on something an event is generated
- So there will be one kafka producer running which writes messages to atopic when an event is generated
- Then Consumer(for Ex: spark application reads from topic and process the data)
Whose responsibility it is to take care of the producer code? A frond end java/Web developer's? Because web developers are familiar with events and tomcat server logs.
Can anyone explain interms of developer and responsibility of taking care of each section.
...ANSWER
Answered 2021-Aug-09 at 13:08In a "standard" scenario, following people/roles are involved:
- Infrastructure Dev: Setup Kafka Instance (f.e. openshift/strimzi)
- manage topics, users
- Frontend Dev: Creating the frontend (f.e. react)
- Backend Dev: Implementing backendsystem (f.e. asp .net core)
- handle DB Connections, logging, monitoring, IAM, business logic, handling Events, Produce kafka Events, ...)
- App Dev anyone writing or managing the "other apps" (f.e.spark application). Consumes (commit) the kafka Events
Since there are plenty implementations of the producer/consumer kafka API it's kind of language agnostic, (see some libs). But you are right the dev implementing the features regarding kafka should at least be familiar with pub-sub.
Be aware we are talking about roles, so there are not necessarily four people involved, it could also just be one person doing the whole job. Also this is just a generic real world scenario and can be completely different in your specific usecase/environment.
QUESTION
really strange error on my side. I am programming a firmware for a Cortex-M4f running Nucleus RTOS. For my application I have some prebuilt static libraries (e.g. libexternal.a) which expect an global struct which must be provided by the application (declared extern inside the static library).
From within my application code I can access the struct just fine, but from within the code of the static library I always get an HardFault interrupt.
Through debugging I found that the processor tries to access the struct on the wrong address. Here is some example pseudo-code:
appconfig.c
...ANSWER
Answered 2021-Jul-08 at 14:46I can't give you a sure-bet smoking gun answer without being able to test it myself, but my guess is the problem is that you're building your library with -fPIC, but your main application is not.
Keep in mind that when you ask the compiler to generate position independent code, you're also asking it to generate position independent data. In your case the global variable g_appconfig is going to be at a fixed location determined by the linker.
Try taking out the -fPIC option on your library build. Since you're only linking statically you don't really need it, and it's more likely to hurt your performance than help.
