Assuming you can't change your txt file to json, if you are looking to only change the LOADLIST that comes after IFSIM, you could use a state to check that the loop has reached IFSIM.

The quicksum method expects a generator expression or a list, not a single variable. Similarly, addConstrs also expects a generator expression. Hence, your first constraints should be written like this (note the extra bracket)

QUESTION

PayPal REST token request: api.paypal.com OK, api-m fails

Asked 2021-Nov-16 at 19:58

Addendum 2:The Mozilla behavior is specific to which host the URL resolves to; I've added curl script showing this at the end of the Question.

Addendum: This had gone away 8 hours later or so, and worked for several days. But a week later, I re-run the page just to check, and it is failing repeatedly again: api.paypal works, api-m.paypal doesn not.

I receive different results requesting a live-site access token from api-m.paypal.com and api.paypal.com. If I make the request to api.paypal.com, it works and a token is returned. If I request it from api-m.paypal.com, I receive a 403 Forbidden error. How is this possible? In general, and for token requests, the documentation seems to use api and api-m interchangeably. What's the difference between the two and what calls should be routed to api vs api-m? When I'm running my whole store on the sandbox, everything goes to api-m and works fine. In a test program that just requests tokens repeatedly, sequencing through api, api-m, api.sandbox, and api-m.sandbox --- only api-m fails, the other 3 cases are good. I saw an api vs api-m discussion once but can't find it again; pretty sure it didn't mention this!

The PayPal REST token request's user-agent must be a curl identifier, such as "curl/7.55.1". Using a Mozilla user agent causes 403 FORBIDDEN on api-m.paypal.com, though it will appear to work on api.paypal.com, api.sandbox.paypal.com, and api-m.sandbox.paypal.com

Picture of error on website

Whenever my code gets to the last line of code, it clicks the convert button which converts a youtube music video to a mp3 file (don't worry I'm doing it with non-copyrighted music), however only the website itself comes up with an error of: Invalid Argument below the button in a red box. I have tried other formats like .send_keys(Keys.ENTER) or .submit(), but they all get rejected to same way. I don't recommend clicking on the 2nd website with the button, as it has some suspicious adds, hence why I'm using brave instead of Chrome.

When using a nested select [1], the value of the column attribute should be a column name in the result set of the first query.
In the result set of your first query, the parameter to the nested query is id, so the @Result should look as follows.

QUESTION

Trying to play a WAV with SDL but getting buzzing noise

Asked 2021-Jun-30 at 16:15

I'm writing this simple program to learn how to work with audio with SDL. The program opens a window with a button that says go and when you hit the button it should play a WAV of a drum sample. There are no errors and the program doesn't crash it's just that instead of playing the drum sound it makes a weird buzzing noise that doesn't stop until you exit the program. I think it's something to do with the audio callback function but I am very new to this so I'm not sure exactly how it works.

...

ANSWER

Answered 2021-Jun-30 at 16:15

The issue may be that you're using SDL_MixAudio.

Your code mixes in the data from the .wav file, but mixes it into what?

What is in stream before calling SDL_MixAudio?

I get the same buzz, but when I use memset to zero out the stream buffer before calling SDL_MixAudio, I get the correct sound from the .wav file.

I don't know for sure but I believe that on the second and subsequent calls to your mixing function, the data from the prior callback is still in the stream buffer.

Side note: When the .wav data has finished playing, we can reset sound.dpos to replay the file again.

Here's the refactored code:

It's probably a resolution issue try changing the name of your constructor parameter to something other than csv like csv_name, because that's what is being referred to when you're actually trying to refer to the imported csv module in the csv.render() call.
