Ask HN: Predicting fusion power breakthroughs based on yesterday's 1'066s record

Hacker News - 42 min 58 sec ago

With yesterday's milestone of 1,066 seconds of sustained plasma operation achieved by the EAST tokamak, I wondered: when might fusion become a viable power source? For simplicity, I defined this as achieving sustained operation for 24 hours.

Here's the historical progress in sustained plasma duration (in seconds):

Year Duration (s) 2006 3 2007 5 2011 30 2016 102 2023 403 2025 1,066 Using this data, I applied several models to predict when 24-hour (86,400 seconds) operation could be reached:

3rd Degree Polynomial: 2067 (poor fit to earlier data) Exponential: 2034 Logistic: 2035 Power Law: 2037 The more plausible models suggest we could reach this milestone in about a decade.

Does this seem realistic? Could other factors (e.g., engineering challenges, funding, or new breakthroughs) significantly shift this timeline?

Ask HN: What are some good, recent books on Java and Java Enterprise?

Hacker News - 50 min 27 sec ago

I came across a book titled Modern Java EE Design Patterns recently, and it got me thinking about what else is out there for the modern Java developer. Books that have come out relatively recently and represent where Java and Java Enterprise is today.

What would you recommend?

Show HN: Go-SQS-Worker – A Simple and Scalable Async Job Library for AWS SQS

Hacker News - 1 hour 3 sec ago

I recently built go-sqs-worker, a Go library for managing asynchronous jobs using AWS SQS. It’s designed to strike a balance between simplicity and scalability, addressing common backend needs like background email processing or task retries without the complexity of Kafka or AWS Step Functions.

Features:

- Clean producer/consumer separation

- Exponential backoff and retry management

- Dead Letter Queue (DLQ) support

To make monitoring easier, I also built a job viewer, inspired by Sidekiq, with features to inspect job details visually.

GitHub: https://github.com/mickamy/go-sqs-worker

Demo: https://github.com/mickamy/go-sqs-worker/tree/main/example

Would love your feedback and thoughts on improving it!

Use Security Champions programs as a template for an AI Champions program?

Hacker News - 1 hour 3 min ago

In a recent podcast episode (https://www.tessl.io/podcast/adapting-your-team-culture-for-ai-devops-lessons-learned-with-hannah-foxwell) where Hannah Foxwell compares lessons learnt with DevOps to allow AI to be adopted easier. Part of it got me thinking about how successful(?) some security champions programs have been in getting app security in particular adopted across development teams, as well as the more company wide need to increase education about basic security hygiene.

Should we use this exact same model with AI Champions? It feels like a lot could be learnt from the way Security Champions programs pulls parts of the org together, particularly where critical guardrails/guidelines are needed.

Should we use Security Champions programs as a template for an AI Champions program? My gut feel is yes and this is needed, and Security Champions programs are for me one of the better ways to achieve this.

Show HN: NotepadJs – A cross-platform love letter to Notepad

Hacker News - 1 hour 7 min ago

As a native Windows user who switched to macOS a few years back, one thing I never got over was the simplicity and usefulness of the old school Notepad app. This app aims to recreate that very same experience, cross-platform and easily installable as a PWA.

I've been using this for personal use for around 2 years and I figured it was time to share it with the world. Criticism, issues and PRs are welcome. Thanks!
