            You can use ESLint's no-useless-escape rule, which will suppress warnings when you use escape characters that don't change the string's meaning. Also see this question and its answers.

            As a bit of extra info, - in a regex only has special meaning if it's inside of square brackets [ ] and otherwise does not need to be escaped. None of the instances in your regex appear to be inside such brackets, so it's safe to say the regex will work the same if you do decide to just remove the escape characters.

            Artefacts when rendering to a framebuffer with alpha blending using WebGL2
            Asked 2021-Jan-03 at 15:45

            I am trying to draw 2D metaballs using WebGL2. I render a bunch of quads with transparent radial gradient and gl.blendFunc(gl.SRC_ALPHA, gl.ONE_MINUS_SRC_ALPHA) to a separate framebuffer. I then use the resulting texture in a fullscreen quad, where I decide if pixel should be rendered based on it's alpha value like so:

            ...

            ANSWER

            Answered 2021-Jan-03 at 15:45

            I'm pretty sure the issue the texture your rendering to is 8bits. Switch it to a floating point texture (RGBA32F) You'll need to check for and enable EXT_color_buffer_float and OES_texture_float_linear

            Update

            You say it won't work on mobile but you're using WebGL2 which hasn't shipped on iPhone yet (2021/1/3). As for RGBA32F not being renderable on mobile you could try RGBA16F. You'll have to check for and enable the corresponding extensions, EXT_color_buffer_half_float and OES_texture_half_float_linear. Your current code is not checking that the extensions actually exist (I'm assuming that was just to keep the code minimal)

            The corruption is that your circle calculation draws alpha < 0 outside the circle but inside the quad. Before that was getting clipped to 0 because of the texture format but now with floating point textures it's not so it affects other circles.

            Either discard if c <= 0 or clamp so it doesn't go below 0.

            Note: you might find coloring faster and more flexible using a ramp texture. example, example2

            Also note: It would have been nice if you'd created a more minimal repo. There's no need for the animation to show either issue

            Update 2

            Something else to point out, maybe you already knew this, but, the circle calculation

            How to make Spring cloud stream Kafka streams binder retry processing a message if a failure occurs during the processing step?
            Asked 2020-Jun-03 at 19:56

            I am working on Kafka Streams using Spring Cloud Stream. In the message processing application, there may be a chance that it will produce an error. So the message should not be commited and retried again.

            Answered 2020-Jun-03 at 19:56

            Spring Cloud Stream Kafka Streams binder itself does not provide such retrying mechanisms within the execution of your business logic. However, one way to solve this use case may by wrapping your critical call (dao.insert() in this case) in a RetryTemplate that you define locally. Here is a possible implementation that retries 10 times with a backoff policy of 1 second. If you are trying this solution out, make sure to extract the RetryTemplate related common code out of your main business logic. I haven't tried this, but it should work.

            JQuery will try and load the scripts included in the HTML files that you're requesting. Is there a reason why you're including them that way?

            Remove all the external script tags and css files from the html partials, or use a different method to include the html partials.

            Also, those partials don't need to have or tags, best case scenario they get ignored, worse case, they affect the way that the browser reads the document and creates unexpected behavior.

            I don't see any namespace in your classes? Can you add how the classes map to the filesystem? There is a PHP-standard called PSR-4 which is commonly used. If this does not meet your requirements, composer offers a few alternative autoloading options that you can specify in your plugin's composer.json.

            See: https://getcomposer.org/doc/04-schema.md#autoload

            For example if your plugin only consists of this one AppHelper class that is kept in a file src/AppHelper.php and the abstract base class you could just add a classmap with those 2 files to your composer.json:
