            Add noise with varying grain size in Python
            Asked 2022-Apr-11 at 03:41

            I am trying to add noise into image to imitate real world noise created by having high ISO settings in camera.

            ANSWER

            Answered 2022-Apr-10 at 21:28

            It's very challenging to imitate the varying grain size noise of high ISO settings.
            One of the reasons is that the source of the varying grain is not purely physical effect.
            Some of the grain comes from digital noise reduction (image processing) artifacts that are different from camera to camera.

            I thought about a relatively simple solution:

            • Add random noise at different resolutions.
            • Resize the different resolutions to the original image size.
            • Sum the resized images to from "noise image" (with zero mean).
            • Add the "noise image" to the original (clean) image.

            A lot of tuning is required - selecting the resolutions, setting different noise to different resolutions, select the resizing interpolation method...

            I don't think it's going to be exactly what you are looking for, but it applies "noise with varying grain size", and may give you a lead.

            How to integrate cognito identity pool with another AWS account for API Gateway access
            Asked 2022-Apr-10 at 09:03

            I have a working project in AWS Account A which authenticates users using cognito user pool. Have successfully limited access to certain API Gateway endpoints (using AWS_IAM authorizers) by using fine grained roles, policies, and identity pool. This is all working fine. Now, I am trying to figure how to get API Gateway end point in another AWS account (Account B) to use these same credentials (AccesskeyId, SecretAccessKey and SessionToken) from Account A to be able to hit the API Gateway end point in account B without creating an identity pool id etc in Account B.

            IMO approach is valid, make sure that APIs resource policy allows only assumed identity role to perform actions (assuming this is your use case).

            You can also change the authorization type to Cognito and use the Cognito user access token and scopes to authorize access. Then you do not need to manage policies, see https://docs.aws.amazon.com/apigateway/latest/developerguide/apigateway-cross-account-cognito-authorizer.html.

            There's quite a bit I don't understand in your code. So instead I'll just give you code that works ;-)

            • I'm baffled by how your code can run at all. A .gz file is compressed binary data (gzip compression). You should need to open it with Python's gzip.open(). As is, I expect it to die with an encoding exception, as it does when I try it.

            • temp[2] is not an integer. It's a string. You're not adding integers here, you're catenating strings with +. int() needs to be applied first.

            • I don't believe I've ever seen asyncio mixed with concurrent.futures before. There's no need for it. asyncio is aimed at fine-grained pseudo-concurrency in a single thread; concurrent.futures is aimed at coarse-grained genuine concurrency across processes. You want the latter here. The code is easier, simpler, and faster without asyncio.

            • While concurrent.futures is fine, I'm old enough that I invested a whole lot into learning the older multiprocessing first, and so I'm using that here.

            • These ngram files are big enough that I'm "chunking" the reads regardless of whether running the serial or parallel version.

            • collections.Counter is much better suited to your task than a plain dict.

            • While I'm on a faster machine than you, some of the changes alluded to above have a lot do with my faster times.

            • I do get a speedup using 3 worker processes, but, really, all 3 were hardly ever being utilized. There's very little computation being done per line of input, and I expect that it's more memory-bound than CPU-bound. All the processes are fighting for cache space too, and cache misses are expensive. An "ideal" candidate for coarse-grained parallelism does a whole lot of computation per byte that needs to be transferred between processes, and not need much inter-process communication at all. Neither are true of this problem.

            Modularize a Redux Toolkit application
            Asked 2021-Dec-19 at 13:24
            The Question

            Is it possible to separate out the feature of an RTK-based application that depend on different slices of a the redux store into separate node packages? Assuming so, what is the best way to do that?

            Background

            We have a large, and growing, app that is based around Redux Toolkit. Where possible we try to separate parts of the application into their own node packages. We find there are a lot of benefits to doing this, including:

            • Maintainability of codebase
            • Fine-grained control over intra-application dependencies
            • Testability

            It's easy enough to do this for cross-cutting things, like logging, http requests, routing, etc. But we would like to go further and modularize the "features" of our app. For example, have the "address book" feature of our application live in a different module than, say, the "messages" feature, with them all composed together via an "app" package.

            The benefits we see here are ones we have found in other codebases and have been discussed in other places. (E.g., here for iOS). But, in brief: (1) you can see and control intra-app dependencies. For example, you can easily see if the "messages" feature depends on the "address book" feature and make explicit decisions about how you will expose the one feature to the other via what you export; (2) you can build fully testable sub-parts of the app by simply having a "preview" package that only composes in the things you want to test, e.g., you could have a "contact app" package that only depends on the "contact" feature for building and testing just that; (3) you can speed up CI/CD times by not needing to compile (TS/babel), pack/minify, and unit test every part; (4) you can utilize various analytics tools to get more fine-grained pictures of how each feature is developing.

            There may well be other ways to achieve these things, and some may disagree with the premise that this is a good way to do it. That's not the focus of the question, but I'm open to the possibility it may be the best answer (e.g., some one with significant Redux experience may explain why this is a bad idea).

            The Problem

            We've struggled to come up with a good way to do this with Redux Toolkit. The problem seems to boil down to -- is there a good way to modularize (via separate node packages) the various "slices" used in RTK? (This may apply to other Redux implementations but we are heavily invested in RTK).

            It's easy enough to have a package that exports the various items that will be used by the redux store, i.e., the slice state, action creators, async thunks, and selectors. And RTK will then compose those very nicely in the higher-level app. In other words, you can easily have an "app" package that holds the store, and then a "contacts" package that exports the "contacts" slice, with its attendant actions, thunks, selectors, etc.

            The problem comes if you also want the components and hooks that use that portion of slice to live in the same package as the slice, e.g., in the "contacts" package. Those components/hooks will need access to the global dispatch and the global useSelector hook to really work, but that only exists in the "app" component, i.e., the feature that composes together the various feature packages.

            Possibilities Considered
            1. We could export the global dispatch and useSelector from the "higher" level "app" package, but then our sub-components now depend on the higher level packages. That means we can no longer build alternate higher level packages that compose different arrangements of sub packages.

            2. We could use separate stores. This has been discussed in the past regarding Redux and has been discouraged, although there is some suggestion it might be OK if you are trying to achieve modularization. These discussions are also somewhat old.

            The Question (Again)

            Is it possible to separate out the feature of an RTK-based application that depend on different slices of a the redux store into separate node packages? Assuming so, what is the best way to do that?

            While I'm primarily interested if if/how this can be done in RTK, I'd also be interested in answers--especially from folks with experience with RTK/redux on large apps--as to whether this is Bad Idea and what other approaches are taken to achieve the benefits of modularization.

            Answered 2021-Dec-18 at 16:17

            This question has come up in other contexts, most notably how to write selector functions that need to know where a given slice's state is attached to the root state object. Randy Coulman had an excellent and insightful series of blog posts on that topic back in 2016 and a follow-up post in 2018 that cover several related aspects - see Solving Circular Dependencies in Modular Redux for that post and links to the prior ones.

            My general thought here is that you'd need to have these modules provide some method that allows injecting the root dispatch or asking the module for its provided pieces, and then wires those together at the app level. I haven't had to deal with any of this myself, but I agree it's probably one of the weaker aspects of using Redux due to the architectural aspects.

            For some related prior art, you might want to look at these libraries:

            Might also be worth filing this same question over in the RTK "Discussions" area as well so we can talk about it further.

            Answered 2021-Aug-07 at 12:36

            Your kernel code looks good and the cache tiling implementation is correct. Only make sure that the number of bodies is a multiple of local size, or alternatively limit the inner for loop to the global size additionally.

            OpenCL allows usage of multiple devices in parallel. You need to make a thread with a queue for each device separately. You also need to take care of device-device communications and synchronization manually. Data transfer happens over PCIe (you also can do remote direct memory access); but you can't use NVLink with OpenCL. This should not be an issue in your case though as you need only little data transfer compared to the amount of arithmetic.

            A few more remarks:

            • In many cases N-body requires FP64 to sum up the forces and resolve positions at very different length scales. However on the A6000, FP64 performance is very poor, just like on GeForce Ampere. FP32 would be significantly (~64x) faster, but is likely insufficient in terms of accuracy here. For efficient FP64 you would need an A100 or MI100.
            • Instead of 1.0/sqrt, use rsqrt. This is hardware supported and almost as fast as a multiplication.
            • Make sure to use either FP32 float (1.0f) or FP64 double (1.0) literals consistently. Using double literals with float triggers double arithmetic and casting of the result back to float which is much slower.

            EDIT: To help you out with the error message: Most probably the error at clCreateKernel (what value does status have after calling clCreateKernel?) hints that program is invalid. This might be because you give clBuildProgram a vector of 2 devices, but set the number of devices to only 1 and also have context only for 1 device. Try
