I've got a workflow where I build a specific image and then (after pushing to an ECR repo and then pulling it onto an AWS server) essentially run it with a docker-compose file. My docker compose file looks as follows:

I'm using Docker for the first time and am running into an issue where I think my main problem is I'm not sure of the source of the issue. I'm running an EC2 instance on AWS, which is properly configured, etc. to host a site.

If I have an update to my git repo, I can manually ssh into the git repo, run

I want to trace complete execution of an HTTP request in golang. For any non trivial operation the request will eventually call many different functions. I would like to have logs from the entire execution stack tagged with a unique request id. e.g.

I am writing a raycaster using SDL's C API. I have spent weeks trying to fix the notorious fisheye effect to no avail. According to this source, I can multiply my calculated distance by the cosine of half of the FOV to fix it. That has not worked for me. I still have the cosine correction in my code nonetheless.

Here are two images demonstrating the distortion:

I think a core problem of my code may be that my angle increment is constant, while the increment should be smaller as I'm closer to the screen borders. Unfortunately, I don't know how to start implementing this.

If possible, could anyone please take a look at my code and give me a tip on how to remove the fisheye? To move in any direction, use the arrow keys. Use the 'a' and 's' keys to turn left and right respectively.

This is how I'm compiling: clang `pkg-config --cflags --libs sdl2` raycaster.c

So I've read the formik docs, and a dozen tuts and examples and I don't understand the most concept of formik and forms.

I am generating random gamer tags, then letting the user rate and organize them. this is all to help me learn react. I need to know which options they want from a list of radio and checkboxes. So I'd love to know in the state of my app (top level), which options the user has picked. Here is an outline of how my app is structured.

I'm trying to create a IDP provider mapper using the keycloak CLI similar to this

The examples in the docs are all for storage mappers.

I've tried

So basically, my app has 10 different tables and graphs being generated for the user as results. Now, what I want to do is, display a checklist for the user and then ask the user to select the items they want to include in their downloaded report. This will make a customized report which will only include the things the user wishes to have. So, please help me out with the process of adding items into a report only if a checkbox is checked. I, kind of, have got the idea that I will have to generate the report with r-markdown but would love to have some clarity on it further.

My actual case is a list of combined header strings and corresponding data as sub-lists; I wish to subset the list to return a list of sub-lists , i.e the same structure, that only contain the sub-lists whose header strings contain strings that match the strings in a character vector.

Test Data:

Given a Chez Scheme record with many numeric fields that are contantly being mutated by small increments and decrements, usually by one, is there a way to write a macro that can mutate a field value by passing it the field? The way I accomplish this now is something like the following REPL transcript:
