Been getting messages asking how I use Codex in my projects. Finally made a video about it!

I break down my entire workflow and share the tips and tricks that make the biggest difference in my daily coding.
Hope it helps 👍

If you’re using Windsurf and not adding MCP servers you’re missing out on serious power.

I’ll show you how to add them from the store and manually (including Snyk!)

I asked Claude Sonnet 4.5 to build a secure Node.js note taking app from scratch. The results surprised me!

Watch here 👇

Clarkio wearing a backward black Snyk cap looking surprised, set against a bright purple and blue background. To his right is an editor window titled 'SECURITY_REPORT.md' displaying a Markdown document describing a 'production-ready, security-hardened Node.js notes application.' Above him is the orange starburst logo for Anthropic, and bold gradient text at the bottom reads 'BEST IN THE WORLD?!' in blue and purple letters.

Stop using .env files for your API keys. They’re not safe anymore.

Here’s why and what to do instead 👇

Spec-driven development + AI = the future? 🤔

I explored Amazon’s new Kiro IDE paired with Claude Sonnet 4 to find out.

Watch and tell me if you’d code like this 👇

Bright thumbnail image featuring a surprised clarkio on the left side, with wide eyes and open mouth. The background is a vibrant mix of purple and pink hues with binary code pattern. Bold text at the top reads 'SPEC DRIVEN DEVELOPMENT' in blue and white. On the right, a UI screenshot shows two options: 'Vibe' and 'Spec,' with the 'Spec' option highlighted, which says 'Plan first, then build. Create requirements and design before coding starts.' A red arrow points to the highlighted option.

I put Replit to the test and was honestly shocked by the outcome. If you care about what AI coding tools can (and can’t) do, you’ll want to see this.

On the right-hand side is text in bold letters "This is crazy!" overlayed on the Replit logo. Above that is a screen shot of the application that was built in the video. On the left-hand side is an image of clarkio smiling. The background is a gradient from purple to blue with circuit lines and 1's and 0's

Is it just me or does this feel off when threads get super long? Makes it harder to read as posts are squished to the side

In response to the video on how AI coding tools make you vulnerable someone said GitHub Copilot Chat tends to provide better results. Spoiler alert: it does!

However it still suggests vulnerable code at times too. See it in action [9min 32sec]: youtu.be/EIdsJsKAkvM?...

Maybe think twice about why you’re going to make that post before publishing it. What’s the true reason for sharing it?
A page from the book “The Daily Dad” on not using your kids. In particular it describes the example of exploiting your kids to get rewarded with likes, comments, followers, etc.

I just came across this tool that visualizes a package's dependency tree. It's called npmgraph: npmgraph.js.org

Here's an example of it with the `rimraf` package:
