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've had some ideas for a game simmering for a while now and I've finally committed to learning Godot to see what I can put together. I'm still in need of some inspiration, though, and I know there's a few folks around here who have made games. Complete, polished, sketchy, half-baked - doesn't matter! - I'd love to see what people here have come up with!

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?

edit: details about earlier convo

What was your first programming language, what other languages (if any) do you know now, and what tips do you have for those trying to learn any of those? Whether those tips are for beginners or even advanced, to do with APIs, or if you've got a good library to share.

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:

1. a different build system that will be easier to manage for this use case
2. a different strategy for using cmake that will be easier to manage
3. 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'm a graphic designer. I've been working in the field for nearly seven years now, two of which in an actual agency. One afternoon I started on a project that was born of more or less pure spite - I love the annual art trading game Art Fight, but absolutely loathe how the game is run, how it comes completely crashing down every year due to people trying to access the site all at once and them not having any contingencies in place, and how the leadership there is apparently only concerned with donations and little community outreach. If you're unfamiliar, artists get sorted into one of two teams, upload their original characters with reference sheets and then draw characters belonging to the opposing team's members. It's great fun, and I tried volunteering for them, but the fact that I'd've to sign an NDA just to be a moderator is just a step too far. For those unaware, the Art Fight team was also caught embezzling donations in one of the last fights, 2022 if memory serves.

So I did what I do best. I started drafting user stories, did UX research, sketched, drew and designed what I'd think would solve all the problems with Art Fight. The result I called PICTOCLASH, and while the process to make and prepare the design took me about four weeks from start to finish, I knew I couldn't actually make the thing work. Disregarding the fact that the Art Fight platform is anaemic and runs on outdated PHP, has no optimisations for image storage or user content and does not buffer or queue database interactions, it's still a massive lift. We don't have numbers on how large AF is, but suffice it to say that it's far larger than any hobbyist project can be without VC involvement.

I was convinced, though, that if one just... approached the problem differently, maybe with modern technologies, the Next.JS I kept hearing about from my web design peers, maybe a shiny new database like Postgres, state management, all the things I know next to nothing about, this could work. My project could work. Yes, it's a lot of work, but it wouldn't be impossible. With a team of developers, all believing and contributing to the project in an open-source way, that's doable. Eminently realisable, even.

So I started. I began reading documentation for TS, Next, React, Prisma, Postgres and all the other things I'd need to read up on. This was maybe half a year ago. But damn, programming got hands. Even the Me-ChatGPT-Dream-Team wasn't enough to have me wrap my head around so many concepts here. I'm a front-end guy, that's for sure. I got my ass handed to me, and in a month, I barely have a login system, and looking at GitHub I could have just went with any of the many pre-rolled solutions.

Which just led me back to my original point. I have three hundred-odd lines of barely functional typescript that holds up an incredibly slow login system. I'm not cut out for this project, and I need to accept that. I'm a designer, I know PHP, I can write valid JavaScript, but... application development? That'll forever be a realm locked off to me.

And of course, the easy way out would just be to look for developers. But I can't do that, at least not without significant risk of falling into the "I had an idea for an app, you wanna make it?" brand of parasite. I'd feel dirty doing that, even if I know that I could more or less to front-end and every visual component by myself. In fact, I have done that. It's just the app part that's missing, and that's unfortunately the major lift.

How do you people cope with this? Because it's not been the first time this happened to me. I keep putting off learning 3D modelling out of exactly that reason, that I could just hit a wall no matter how hard I try. It's frustrating, and looking back how easily I picked up other disciplines in university it really makes me wonder if there are some things my brain just can't learn. I don't think I'm ready to accept that.

Edit: For anyone interested, I uploaded the abridged design document to my website.
