Déjà Vu: AI Agent Frameworks and the JavaScript Gold Rush Revisited

07 Dec 2024

Having lived through the era of a "new JavaScript framework every week," we now find ourselves in the gold rush of the AI agent framework space.

New frameworks appear daily, each claiming to be the 'ultimate' solution for building AI agents, often backed by YouTubers enthusiastically promoting demoware and usually their own library, framework, or SaaS offering. Unfortunately, this enthusiasm can lead companies to uncritically adopt these tools without considering the long-term implications.

Sometimes Boring is Best

26 Oct 2024

As I stood in the rain as a volunteer race marshal at my local park run, it occurred to me that I wanted the same thing when running applications in production, and that's absolutely nothing to happen.

The last thing I wanted to do was be a hero.

Me in the rain volunteering for Parkrun

🎸 "Always keep on the right side of the path" – the Parkrun version of Monty Python's song.

I'd rather everyone enjoy a safe, smooth race where I can cheer and encourage people on as they pass, reminding them to keep to the right so they don't collide with runners coming the other way.

It's the same in the land of IT. The only thing I want to see when viewing Grafana dashboards is a sea of green, 200 status codes and steady traffic patterns.

Don't Look Back in Anger: Let's Design a Better Ticketing System

31 Aug 2024

Saturday's Oasis ticket sales left thousands of fans disheartened after spending hours in virtual queues. As reported by the BBC and echoed by fans on X (formerly Twitter) and Reddit, the experience could be aptly described using a quote from Liam Gallagher himself:

Like many others, I have long been frustrated with platforms like Ticketmaster, See Tickets, and Gigs and Tours. This weekend, their reputations took another hit as fans faced inflated prices and technical glitches.

This made me think if I could design a better, more reliable ticketing system that prioritises fairness and user experience.

Let's not make Sally wait any longer than she has to.

The Leadership Gamble: Why Fighting for Your Team Is Essential for Success

06 Aug 2024

I've been fortunate to work with some incredible leaders throughout my career.

These individuals have inspired and challenged their teams and driven them to achieve their full potential.

What truly sets a leader apart, however, is their ability to motivate and their willingness to fight for their team.

There's something special about a leader who fights for their team.

In this post, I'll explain what happens when a leader truly stands up for their team, sharing my firsthand experiences from a transformative project at Cambridge Assessment in 2007.

A close-up image of an exam answer sheet titled 'Leadership' at the top. The sheet features a multiple-choice section with bubbles filled in. A hand is seen holding a pencil, and a bold red 'A+' grade is hand-drawn and circled in the center of the sheet. The overall setting has a realistic, academic feel, highlighting the theme of evaluation and achievement

The Fine Line Between Frustration and Desperation

16 Jul 2024

As an England football fan, I know the feeling all too well. The heartbreak of watching your team come so close, only to fall short at the final hurdle once again. It's now 58 years of hurt.

It's a mixture of emotions – frustration, disappointment, and knowing the team could have done more.

I've experienced a similar feeling in my work as a consultant.
