Jess Lee — Thu, 02 Jul 2026 22:04:04 +0000

We are so excited to finally announce the winners of the GitHub Finish-Up-A-Thon Challenge, our celebration of finishing what you started by reviving abandoned side projects, hackathon creations, and long-forgotten repos with help from GitHub Copilot.

First things first: thank you all so much for your patience. We know this announcement took longer than expected, and we're grateful you stuck with us while we gave every submission the careful review it deserved.

The comeback stories you shared were incredible. Your work showed us that no project is ever truly dead, it's just waiting for its second act.

Now, let's celebrate our ten winners!

🎉 Congratulations To…

Play today’s game from Issue #2 of The Daily Context!

Jess Lee — Tue, 30 Jun 2026 22:10:45 +0000

Yesterday, we kicked off our physical newspaper, The Daily Context, at the AI Engineer World’s Fair with "Vector Search." Thank you to everyone who played it online!

Today is Day 2 of the conference, which means Issue #2 of the newspaper is officially out on the floor. For today's puzzle, I wanted to change things up. Say goodbye to the word search grid and hello to...

Context Connections:

Just like yesterday, I built this using AI Studio and deployed it to Cloud Run.

Let me know if you solved the puzzle within four tries!! There are a few tricky ones in there 😈

Need a break? Play today's game from The Daily Context.

Jess Lee — Mon, 29 Jun 2026 20:00:00 +0000

We (at DEV and MLH) are covering AI Engineer's World Fair by printing a physical newspaper called "The Daily Context" everyday of the conference.

We wanted to include a game in each issue so for today's first edition, we published a little word search affectionately named "Vector Search":

I built this game with AI Studio and deployed it to Cloud Run. It was super easy to put together and I love the little touches included in the game (answer reveal, confetti upon completion, etc). You can play it right here:

I discovered a funny little "bug" this morning right when we were about to go live with the digital version of the paper.

Or well, maybe I can't actually call it a bug. AI Studio went above and beyond and built me an app where the word search changed on every refresh as opposed to the static word search I had printed in the physical paper. The words being searched remained the same, which is why I didn't notice this immediately.

While a new word search is definitely a better gaming experience, attendees were told to visit the digital version of The Daily Context for their answers so I had to quickly simplify the app to ensure the print and digital versions matched. Certainly a type of problem that wouldn't have happened pre-AI!

Thank you to everyone who responded to my post last week:

Congrats to the Hermes Agent Challenge Winners!

Jess Lee — Thu, 18 Jun 2026 22:13:44 +0000

We are thrilled to announce the winners of the Hermes Agent Challenge! Over the past few weeks, the DEV community dove headfirst into one of the most exciting open-source agentic systems on the scene, and the submissions absolutely delivered.

The range of what people built and wrote left us genuinely impressed — Hermes' memory architecture got a thorough cognitive-science breakdown, the cost curve of a self-improving agent got stress-tested in production, someone built a full immune system for stress-testing AI agent safety, and a Linux desktop HAL was shipped entirely by AI agents. These are just a few of the standout submissions that made judging genuinely hard.

Now, without further ado, let's celebrate our winners! 🎉

Build With Hermes Agent Winners 🏆

From an offline-first emergency response platform to a 25-agent legislative simulation, the Build submissions pushed Hermes into genuinely ambitious territory. What stood out across the board was how purposefully each project used Hermes' agentic capabilities — not as a wrapper around a chat model, but as the actual load-bearing infrastructure. Parallel task delegation, persistent memory, scheduled autonomy, and model-agnostic routing all showed up in real, working builds.

Write About Hermes Agent Winners 🏆

The Write submissions gave us useful breakdowns and genuine perspective. The strongest pieces ranged from practical setup guides to sharp critical arguments — about the self-trust issue baked into Hermes' skill architecture, what persistent memory actually changes about the developer experience, and when local agents earn their complexity. Whether you're just getting started with Hermes or already running it in production, there's something here for you to sink your teeth into.
