I've got a notion to put some of my extra energy into learning to code. I'm familiar with EXTREME basics - I did some coding in BASIC and Python when I was younger ("Hello world" type stuff, and some futzing around with my Ti calculators programming capabilities) and while I had a pretty good knack for it I never developed it further.
I'd like to use this as a chance to create something useful for me - a discord bot for my server. We have a handful of bots doing a few odds and ends, and I'd like to try and work something out to consolidate things. That's getting a bit ahead of myself though - initial scope would be simple: have the bot do a simple task like counting +rep points, or something silly like telling a joke.
I don't really have any idea of where to start - what resources I need, what language to use, or really anything about how this all works. Any assistance at all would be welcome!
To be clear - I want to learn to code, and specifically I want to learn in a way where it is immediately applicable and useful in a context I care about.

I asked Claude for references to some ideas the ai had output earlier about a 16th century cardinal (Sadoleto). It's response was, Let me analyze the letter, and then this:
async function searchForSadoletoLetter() { try { const files = ['sadoleto_letter.txt', 'sadoleto.txt', 'sadoleto_to_geneva.txt', 'letter_to_geneva.txt']; for (const filename of files) { try { const content = await window.fs.readFile(filename, { encoding: 'utf8' }); console.log(`Found file: ${filename}`); console.log("First 500 characters:"); console.log(content.substring(0, 500)); return content; } catch (err) { // File not found, try the next one } } console.log("Could not find any files containing Sadoleto's letter"); return null; } catch (err) { console.error("Error searching for files:", err); return null; } } const content = await searchForSadoletoLetter(); // Since we don't have the letter available as a file, let's search for published versions online console.log("The letter isn't available as a file. We would need to rely on scholarly knowledge about Sadoleto's letter to Geneva (1539)."); console.log("Sadoleto's letter was published in 'A Reformation Debate: Sadoleto's Letter to the Genevans and Calvin's Reply' (ed. John C. Olin).");
This strikes me as odd? Did Claude write a script to generate its own response? Have coders put something like this in as a gaurdrail?

Cmake strategies or alternatives for building (different) code for different platforms

Okay, so this is getting really long, I'll put the ask up front: I have a strategy, I think it is reasonable. Now is a point where I can easily change things, and it won't be so easily later. So I'm looking to see if anyone has trod this road before and can recommend any of:
- a different build system that will be easier to manage for this use case
- a different strategy for using cmake that will be easier to manage
- any gotchas I should be aware of, even if you don't have better solutions.
Background
I have a project I'm working on where the ultimate deliverable will be a hardware device with 3-4 different microcontrollers coordinating with each other and interacting with a PC-ish platform. This is a clean rewrite of a C++ codebase. Due to the microcontroller (and some of the PC APIs) being C++, the language of choice for most of it is likely to remain C/C++.
I'm succeeded in setting up a build system for embedded code. The old code was arduino, so it relies a lot on those libraries, but I've managed to set up enough custom cmake to get off of the ardunio tools altogether, even if I am borrowing their libraries and some of the "smarts" built into the system about setting build flags, etc. So far, I have a dockerized toolchain (cmake + make + gcc-arm-none-eabi) that can successfully build ARM binaries for the target platform.
The thing that I'm up against now is that I'd like to have a robust off-target unit testing infrastructure. My ideal case is that everything in the embedded system will be broken down into libraries that have clear interfaces, then to use unit tests with mocks to get high coverage of test cases. I'll still need some HIL tests, but because those are harder to set up and run, I want to use those for integration and validation.
In terms of OSes available, we're mostly working on Windows systems using WSL for linux. I'd like things to be as linux-based as possible to support CI on github, etc.
Goals and Cmake limitations
I started out using cmake because I hate it least of the tools I've used, and I am at least pretty far up the learning curve with it. But a limitation I'm hitting is that you can't do a mixed compile with two different toolchains in one build. The reasons why cmake has this limitation seem reasonable to me, even if it is annoying. You can easily change the toolchain that your code is built with, but that seems to be largely targeted at cross-compiling the same binaries for different systems. What I want to do is:
- build my code libraries with embedded settings for linking to the embedded binaries and build those embedded binaries (the end product)
- build my code libraries with linux-ish tools and link them against unit tests to have a nice CI test process
- (eventually) also be able to build windows binaries for the PC components -- when I get to that point, I'd like to get away from the MSVC compilers, but will use them if I have to
Current strategy
My current plan is to configure a library build like this (pseudocode):
add_library(mylib sources) if (BUILD_TYPE STREQUAL BUILD_TYPE_EMBEDDED) <embedded config> elseif (BUILD_TYPE STREQUAL BUILD_TYPE_LINUX) <linux config, if any> endif() #unit tests are built for each library if (BUILD_TYPE STREQUAL BUILD_TYPE_LINUX) add_executable(mylib_test sources test_sources) target_link_libraries(mylib gtest etc.) endif()
For the rollup binaries, I make the whole target conditional
if (BUILD_TYPE STREQUAL BUILD_TYPE_EMBEDDED) add_executable(myembedap sources) target_link_libraries(mylib) endif()
Then the build script (outside cmake) is something like
cd build/embedded cmake <path to src> <set embedded toolchain> -DBUILD_TYPE=embedded make cd ../../build/linux cmake <path to src> -DBUILD_TYPE=linux make
Things I like about this strategy:
- It's relatively simple to do all the builds or just one of the builds (that control would go in the shell script)
- I have one source tree for the whole build
- It lets configuration be near code
- It lets tests be near code.
- I think it's extensible to cover the PC component builds in the future
Things that worry me:
- It feels like a hack
- Support for off-target tests feels like it should be solved problem and I'm worried I'm missing something
Thanks for reading. If you made it this far, you have my gratitude. Here's a video with funny out of office messages that I enjoyed.

Hi folks--
To those more knowledgeable than I am:
What would be the best local solution to extract numerical data from a batch of PDF file reports? The values I want are interspersed among word processor formatted tables and irrelevant text. The text and table formatting are (nearly) identical across reports. The data I want vary across reports. The PDFs are not of images...I can select and copy text without OCR. I have thousands to process, and the data themselves are confidential (I have clearance) and cannot be shared. I can use Windows or Linux but no MacOS.
I am technically inclined, so I bashed my head against regular expressions just enough to use notepad++ to find and delete most of the irrelevant stuff and make a CSV, but it's a hacky, imprecise method and not nearly automated enough for batches. For reference, I don't code for a living or even as a hobby, but I use R and bash, am familiar with IDEs, and can follow pseudocode well enough to edit and use scripts.
Any thoughts? Thanks in advance!

I've been feeling pretty bored for a while and my job isn't really giving something fulfilling to do, So I want to make something.
However, I don't want to make something useless. unfortunately, I can't think of any software I'm in a particular need for. I would love to make something that solves a real problem for a real human.
So, please tell me, what's something that you wish existed because it would reduce suffering in your life that little (or big) bit?
Edit: Wow wow and wow, I didn't expect this thread that I made on a whim to blow up so much. So many idead!
