            Slow code when fetching data from Coinmarketcap api
            Asked 2022-Apr-03 at 09:47

            I have the below code that fetches data from Coinmarketcap api and sends me a telegram message when parameters are met. When I fetch 100 coins then the code works fine. But when I fetch 5000 coins the code is very slow. The schedule time with refresh api is not the time that I have code.

            Can someone see why the code is slow with fetching data from the api with 5000 coins?

            A good answer is insert httpx / asyncio in the code. (answer Pawel Rubin (thanks). Does someone know how i can insert asyncio into the code?



            Answered 2022-Apr-01 at 13:50

            The code is making requests sequentially for every element in parsed['data'].

            Consider running your code asynchronously with some HTTP client that supports asyncio, for example httpx, and use asyncio.gather to run your requests concurrently.

            Consider the following example which makes 50 GET requests to google.com using requests and using httpx. Note that the async solution is significantly faster.

            RenderTexture transparency working in editor becomes solid color in build
            Asked 2022-Feb-21 at 20:04

            I am currently trying to get my growth algorithm to work on a texture.

            When running in the editor everything works as expected, however once I build the project, the whole RenderTexture becomes a solid color (red, green or blue [R8G8B8A8_UNORM] depending on the color format) with the simulation on top.

            I have already tried to use an HDRP unlit texture shader instead of my custom transparency shader, which produced the same issue leading me to believe that my mistake lies somewhere within the compute shader drawing onto the texture. Also, I rebuilt the project using URP which unfortunately also produced the same result.

            One other thing, I recently noticed that minimizing and maximizing the game window on runtime in the editor more than once crashes unity although I can't image how this has anything to do with the issue at hand.

            EDIT: Just built the same project for windows (DX11) which works perfectly. This therefore seems to be an issue with the Metal API.

            Interestingly, the maximizing/minimizing problem appears only if vsync is enabled and the touchpad gesture is used.

            Unity Version 2021.2.12f1 using the HDRP on MacOS Monterey 12.2.1.

            To capture multiple times

            • run the regexp on the big string
            • if no matches, break
            • use the second and third capture groups as you like
            • get the first capture group
            • in the big string replace that capture group with an empty string
            • do it again with the modified string

            Old Answer


            I included capture groups if your interested

            I can explain it if you'd like

            • XX\. The beginning is probably obvious. XX\.
              • it's important to note that . in regex matches anything, however I assume you specifically want to get a period. Thus we escape it like \.
            • [A-Za-z]* next we are matching any amount of characters from capital A to capital Z and lower case a and lowercase z. I assume that it will always be 2 characters but I'll let it slide for now
            • \( next we escape the open parenthesis because parenthesis represents a capture group
            • " next we look for a quotation mark
            • (.*)" next we capture anything intil we hit another quotation mark.
              • It's important to note that if the string has an escaped quotation mark, this regexp breaks. If you need an escaped quotation mark also I'll try to help you out
            • , next we look for a comma
            • \s* after that we look for any amount of spaces. Could be zero, could be a hundred
            • (0-9A-Za-z){2} next we capture two characters that could be 0-9 A-Z and A-Z
            • \) finally we end with a parenthesis

            Answered 2022-Feb-07 at 02:28

            I think the issue might be that zx is using the bash inside WSL. Assuming you also don't want to use ffmpeg in WSL, here is how I fixed it.

            1. Install git.
            2. Find the bash.exe inside the installed git. In my case, it is located at C:/Program Files/Git/usr/bin/bash.exe.
            3. Insert the following line after the shebang: $.shell = `Location to your bash`. In my case, it is $.shell = `C:/Program Files/Git/usr/bin/bash.exe`;.

            I am fairly sure this works with other distributions of bash for Windows, but I have not tested.

            I tried to replicate your problem but I had to remove the styles since you did not provide them. It works at my side, so perhaps the problem lies within the style?

            Please delete your styles for the textboxes (ParameterTextbox) and see if it works then. If you can provide me with the source code for the style, I can take a look at it. Maybe you are overriding the text property.

            edit after it turned out the style was the issue

            here is an example of the style you want to accomplish in a minimalistic way.

            Firestore 'await addDoc' (Web version 9) hangs forever when network connection is lost
            Asked 2022-Jan-03 at 15:57

            I'm using Firestore 'addDoc' (Web version 9, https://firebase.google.com/docs/firestore/manage-data/add-data) to add a new document:



            Answered 2022-Jan-03 at 15:57

            This is the expected behavior: the promise from addDoc is only resolved once the write operation is completed on the server. If you don't want to wait for that, don't use await.

            If there is a problem with the local write, addDoc will raise an exception. Only when there is a problem with the write on the server, will it reject the promise.

            In v8 and before you could get the DocumentReference without await by using collection.doc(). See the last snippet in the documentation on adding a document for how to do this in v9 too:

            In some cases, it can be useful to create a document reference with an auto-generated ID, then use the reference later. For this use case, you can call doc():
