Another amazing conversation with @DaveBlundin getting into some of the nitty gritty details of making AI accessible to everyone and a lot more. What a blast as always, and thank you for having me on the show! 🚀 💪

Just posted Round 2 with Freedom Dumlao (@APIguy), CTO & CAIO at @Vestmark, and somehow the conversation got even better than the first one!
A few weeks ago, Freedom told us how all 400 Vestmark employees have access to Claude Code. In this episode, learn about the freshly installed rack of Mac Minis now running AI agents at Vestmark, why running inference through AWS Bedrock instead of the Claude.ai API is an unlock for enterprise, and why small fine-tuned models like Gemma 12B are about to eat a huge chunk of the enterprise AI workload.
Thank you Freedom for returning to the Link Ventures podcast studio!

Fine tuning small models is the skill most engineers are still missing from their tool belt. If you aren't learning how to do this yet you are way behind.

Google just dropped a new LLM!
You can run it locally on just 8GB RAM.
Let's fine-tune this on our own data (100% locally):

If you're still waiting for AI to be "ready," you are already way way behind.

If you wait for AI to be "ready," then you're already behind.
Someone who saw it coming is already way ahead of you. The edge goes to whoever prepares now and is ready the moment the door opens.
One of my favorite moments from this AMAZING episode with Freedom Dumlao (@APIguy) from @Vestmark 👇

By far the most common comment I'm getting from my most recent podcast appearance: "why don't you have any stickers?!"
It's a new laptop people! Which stickers should get first dibs?

Had absolute blast talking with the one and only @DaveBlundin - it's always a great conversation and love swapping notes on AI, and the future of work

It was an absolute pleasure to sit down with Freedom Dumlao (@APIguy), CTO & CAIO at @Vestmark where he and the team are shipping AI inside a highly regulated, $2T wealth tech platform.
In this episode, learn about how all 400 employees at Vestmark use Claude Code, how they've built agentic systems like Pulse that prompt the advisor instead of waiting to be prompted, and how Fabric allows anyone in the company to spin up and share skills in 3 minutes.
Most banks are still rolling out Copilot to "a handful of test users this summer." Freedom is at least 18 months ahead of that and gaining steam. Thank you Freedom for joining me in the @Link_Ventures podcast studio!

Way back in 2010 I had strayed far from Ruby-land and was spending much of my time working in C# writing Silverlight and WPF code. I missed Ruby and wouldn't you know it, IronRuby burst onto the scene! 🧵

So I went looking. It took a few hours but I finally found the original blog post about it too. I repurposed that, created a readme, and pushed it up to GitHub where it now lives.

If you're interested in a piece of programming history, an IronRuby DSL for XAML based UIs, here it is in all it's glory: github.com/apiguy/kiddo resurrected from the dead.
