Patrick Hartley is a self-taught developer with nearly a decade of software engineering experience. When he was 21 he had to dropped out of college to provide for his family. He taught himself programming while working at a thrift store.

After building his own apps and freelancing, he became the founding engineer at startup that got acquired, and has since worked as a dev at other tech companies. A few months ago he turned down an opportunity at Amazon so he could continue to work remotely from his home in Oklahoma City.

He shares tips for: - Teaching yourself programming while raising kids - How to build foundational skills with JavaScript and Python - Getting a remote job when you have to compete with the global developer talent pool - Surviving as an introvert in a networking-heavy and meeting-filled profession

Tom Mondloch quit programming after he finished community college. After a few years of odd jobs, he decided to get back into programming and discovered freeCodeCamp.

He was just learning his own way, and didn't think freeCodeCamp's linear curriculum would be worth his time. But he stuck with it, got good, and ultimately started contributing to our open source project.

He's since joined freeCodeCamp's staff and archetected freeCodeCamp's entire relational database curriculum, which you can run in your browser or right inside your VS Code editor.

Tom shares tips for: - Brushing up on your programming skills if you've taken a few years off - Contributing to open source - Using AI codegen tools sensibly and not relying too heavily on them

He also talks about the role of vocational college, his love of the outdoors, and how working remotely allows him to continue to live in small town middle America without the need to move to a big city.

For this week's interview, we've got a special treat. I'm talking with two legends in the self-taught developer community.

Danny Thompson worked for 10 years at a Tennessee gas station, frying chicken for people to eat, sometimes working 80 hour weeks just to provide for his family. And yet, Danny had ambition. He taught himself to code using freeCodeCamp. He built his network through local tech events. And eventually, he landed his first job as as software developer. He's since worked at tech companies like Google.

Leon Noel grew up with everyone telling him he had to become a doctor, lawyer, or dentist. He skipped college, taught himself programming, and had a successful exit with a startup. Leon then turned his attention to helping folks who were struggling during the pandemic. He started 100Devs, a charity which has helped thousands of people learn to code.

Danny and Leon run the Programming Podcast which you can find in the podcast player freeCodeCamp iPhone or Android app, along with other podcasts we recommend.

The following 45 minute conversation is almost entirely focused on the developer job market - perfect if you're looking to getting a new job.

You'll learn common misconceptions people have about Résumés, Recruiters, Applicant Tracking Systems, Knock Out Questions and more. We also talk about the Commit Your Code conference happening September 25 and 26 here in Dallas. Tickets are super cheap and all proceeds go to charity. I'll be there and I hope you'll be there, too.

freeCodeCamp just published a handbook that will help you learn about AI-assisted coding, straight from a software engineer who's maintained freeCodeCamp's platform and infrastructure for the past 7 years. Mrugesh was initially skeptical of AI tools but has recently used them to great effect. And he wrote this handbook to help you do the same. He says experienced developers can complete tasks faster with AI assistance. But they need to know how to use these tools effectively. And they also need strong foundational programming skills. This handbook is a no-nonsense guide to emerging tools and best practices.

This week I read a pretty well researched article on the role of AI codegen in actually getting things done as a developer. The author has more than 25 years of experiencing building software. And he argues that if AI tools really gave devs a big productivity boost, we should see this in the numbers. Specifically, shovelware, which is essentially fast, cheap software projects. And he says we don't really see this. Github repo creation is flat, apple and android app store registration is flat, domain name registration is flat. So he argues these tools aren't actually helping people write code faster and it's just marketing hype. I definitely recommend you read the article after this podcast and I've included a link to it in the description. https://mikelovesrobots.substack.com/p/wheres-the-shovelware-why-ai-coding

→ freeCodeCamp also published this comprehensive course on how to build your own AI shopping agent. Software Engineer Ania Kubów will teach you how to use Node, TypeScript, LangChain's LangGraph, Gemini, MongoDB, and other popular tools to build your agent. By the end of this course, your agent will be able to autonomously perceive, plan, act, and respond to your users. It will also be able to decide when it has enough information to respond, and when it needs to first reach out for external information by searching product databases.

→ This week YouTube channel Gamer's Nexus posted a 3 hour documentary about China and the Graphics chips they've been using to train their AI models. The video has been copyright claimed multiple times by Bloomberg and taken down, but people keep re-uploading it. It's pretty awesome. The channel host travels to Hong Kong, Taiwan, Shenzhen, and Singapore to interview people along the process who are obtaining this hardware both legally and illegally. Note that this link I'm sharing may already been taken down by the time you click it, but you can search "gamers nexus GPU" and you should be able to find it. 3.5 hour watch: https://www.youtube.com/watch?v=kkNBZeS1OHk

→ The open source maintainer of the extremely popular Curl command line tool posted this excellent talk about AI slop security issues he keeps getting. He explains how people seem to be going into LLMs and asking "Find me a vulnerability in the Curl project. Then write a bug bounty submission for me and make it sound as alarming as possible." LLMs keep hallucinating new bugs, which lazy people then submit. Reviewing such bugs is now taking up more and more of his day. Since security is pretty important, he kind of just has to take these submissions seriously. A lot of non-native English speakers use LLMs to make their writing sound more native. But of course, most developers can tell when something's been written by an LLM. At the end of the talk, someone in the audience asks him point blank: has he ever received an issue that reads like LLM output that turned out to be a real security issue? And he says point blank: no. The lesson: don't use LLMs to re-write your issues or pull requests for you, or developers may assume the whole thing is just AI slop. 50 minute watch): https://www.youtube.com/watch?v=6n2eDcRjSsk
