            should I check pointers in such situations?
            Asked 2022-Mar-26 at 21:17

            I'm new to programming and game development in general every time I read and hear that pointers are a nightmare I want to ask if it is necessary to check pointers in such cases as shown below?



            Answered 2022-Mar-26 at 20:44

            As David G and ChrisMM said, it is necessary to check the pointer if the CreateDefaultSubobject function has a possibility of failing or returning a null pointer. If the function is known to always return a valid object, checking may not be necessary in that case.



            module web worker workaround
            Asked 2022-Mar-22 at 17:52

            I am working on a JavaScript application that will do some computation on the client side (inside the browser). However, the computation is later to be found quite expensive, and running them in the main thread will block the UI. So I decided to run them in the web worker.

            Since the logic for the computation is already written in JavaScript modules and bundle with webpack (they are typescript modules as part of a react app, to be exact), the most natural approach is to use worker with type module. However, as in 2022, this feature is not supported in older browsers, in particular, Firefox does not support it. This prevents me from using this feature.

            With only the classic worker, the only solution I can came up with is to copy all these modules (and their dependency) into a single js file, which will be a nightmare for maintainability. Are there any way to workaround this issue (for example, generate this single js file programmatically without messing with existing code)? In particular, since I am using webpack, I thought about creating a separate bundle of all the module code for the worker. But I am not familiar with webpack enough to try that.



            Answered 2022-Mar-22 at 17:52

            WebPack version 5 offers worker support out of the box.

            It's relatively easy to include worker-loader to get something similar working in Webpack version 4.

            However, if the goal is to have a conversation with the web worker (i.e. passing parameters, getting results), then it might be worth looking into Google's comlink or even integrating the comlink-loader into your webpack configuration.

            Comlink makes WebWorkers enjoyable. Comlink is a tiny library (1.1kB), that removes the mental barrier of thinking about postMessage and hides the fact that you are working with workers.



            Vue/TypeScript/ESLint/Prettier/Vetur formatting doesn't work
            Asked 2022-Feb-15 at 21:01

            Trying to get Vue/TypeScript/ESLint/Prettier/Vetur formatting in VS Code is a nightmare. There are many many GitHub issues and StackOverflow posts on this but I assure you this is not a duplicate. I have followed every tutorial and none of them work. Some of them fix one problem but introduce another. Some of them don't fix any problems. Some of them crash VS Code. Most conflict with each other in the advice they prescribe, including multiple official sources. Many are outdated, referencing obsolete config properties.

            I want VS Code to lint and format my .vue and .ts files when I save.

            I have spent hours and tried many, many configurations from different posts and tutorials, but this is the closest I have gotten to something that works. With the below configuration, however, whenever saving a .vue file, elements in the .vue files get momentarily wrapped onto a new line, and then immediately reverted back to a single line element:

            then then

            To get Vue/TypeScript/ESLint/Prettier/Vetur working in VSCode, I followed the following steps:

            1. Installed the Vue eslint plugin by running vue add @vue/cli-plugin-eslint. NOTE: If you have a client folder directory and a server folder directory, you must first cd to your client directory before using vue add.
            2. Changed the .eslintrc.js in my Vue project. Please check this post for more information/alternatives. Basically, I made a new Vue + Typescript project and copied the eslint config to my real project. The boilerplate code didn't work completely at first so I modified it a bit:



            Tensorflow setup on RStudio/ R | CentOS
            Asked 2022-Feb-11 at 09:36

            For the last 5 days, I am trying to make Keras/Tensorflow packages work in R. I am using RStudio for installation and have used conda, miniconda, virtualenv but it crashes each time in the end. Installing a library should not be a nightmare especially when we are talking about R (one of the best statistical languages) and TensorFlow (one of the best deep learning libraries). Can someone share a reliable way to install Keras/Tensorflow on CentOS 7?

            Following are the steps I am using to install tensorflow in RStudio.

            Since RStudio simply crashes each time I run tensorflow::tf_config() I have no way to check what is going wrong.



            Answered 2022-Jan-16 at 00:08

            Perhaps my failed attempts will help someone else solve this problem; my approach:

            • boot up a clean CentOS 7 vm
            • install R and some dependencies

            Testing side effects in React Typescript components with Jest and enzyme
            Asked 2022-Jan-05 at 22:58

            I'm really trying to get an understanding of how to properly unit test with React + TS, but it's really been tough going so far. I have two very simple components I'm using to isolate things. I'll include the components at the bottom so I don't clutter things too much.

            Pretty simple, click the Button and the change from 'hello' to 'world' in the state variable data is displayed in InnerComponent. From everything I've seen, the pattern is to test for side effects in the document rather than trying to test the state changes themselves (and thank goodness for that, I had a nightmare of a time trying to access state in the wrapper instance with Typescript). However, eslint hates screen and TS cannot find findByText. Instead I get the error Property 'findByText' does not exist on type 'Screen'.ts(2339) on the noted lines in the test below:



            Answered 2022-Jan-05 at 22:58

            There is a separate "screen" object exported from '@testing-library/react'. that has the findByText method. you unfortunately have to manually grab screen out of the library as auto imports just think its the global "screen" when you don't import explicitly.

            Answered 2021-Nov-09 at 15:11

            I suggest using gradles suggested project structure and have both code bases and the java core be a separate subproject. The project JavaFx and Android can both depend on the java project. Then you can either build just one of them or both. Gradle will automatically rebuild the java base as well, when needed.

            How can I create row and children related by ForeignKey with RoomDB in a clean way?
            Asked 2021-Oct-09 at 23:23

            This question is somehow related to my last question, because it is the same project but now I am trying to go one more step forward.

            So, in my previous question I only had one table; this time I have two tables: the new second table is supposed to contain related attributes for the rows of the first table, in a OneToMany relationship. So, I store a ForeignKey in the second table that would store the Row ID of the first table's related row (obviously).

            The problem is this: the intention is creating both registers (parent and child) at the same time, using the same form, and ParentTable uses AUTO_INCREMENT for his PrimaryKey (AKA ID).

            Due to how RoomDb works, I do the creation using a POJO: but after insertion, this POJO won't give me the auto-generated ID as far as I know... so, the only workaround I am able to imagine is, when submitting the form, first make the INSERT for the parent, then using one of the form's fields that created the parent to make some kind of "SELECT * FROM parent_table WHERE field1 LIKE :field1", retrieving the ID, and then use that ID to create the child table's POJO and perform the next INSERT operation. However I feel something's not right about this approach, the last time I implemented something similar this way I ended up with a lot of Custom Listeners and a callback hell (I still have nightmares about that).

            About the Custom Listeners thing, it is the solution I ended up choosing for a different problem for a different project (more details about it in this old question). Taking a look to that old question might help adding some context about how misguided I am in MVVM's architecture. However, please notice the current question has nothing to do with WebServices, because the Database is purely local in the phone's app, no external sources.

            However, I am wondering: isn't this overkill (I mean the INSERT parent -> SELECT parentID -> INSERT child thing)? Is it inevitable having to do it this way, or there is rather a more clean way to do so?

            The "create method" in my Repository class looks like this:

            You are on the right track. A clean way would be to wrap it in a function like this:
