Of course. Just choose a different model in VS Code.

If like me, you're a nerd that gets excited about research on economic growth, why some countries are richer than others, and the economics of innovation, take a look at Stanford Prof. Charles Jones' papers here: web.stanford.edu/~chadj/cv.html

TY to the economist for the references.

So apparently creators only capture about 2% of of the surplus they create!
This figure is so shockingly low that economists have suggested that the welfare-maximising marginal top rate of income tax should be reduced up to.. a negative 26%!

GitHub - Duartemartins/rails_copilot_instructions: Canonical Rails instructions for the VSCode Github Copilot Canonical Rails instructions for the VSCode Github Copilot - Duartemartins/rails_copilot_instructions

The repo is here:
github.com/Duartemartin...
Feel free to star, fork, or suggest improvements, especially as Rails keeps evolving. #rubyonrails #copilot #vscode

To get started:
Drop the .github/instructions folder into your Rails 8 app
Open Copilot Chat in VS Code
Prompt away. It’ll now suggest code that follows your stack and conventions

11.05.2025 16:25 πŸ‘ 0 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

Rails follows an 'omakase' approach: a curated stack that works well together and reduces decision fatigue. Copilot can now lean into that, leveraging convention over configuration to become a productivity beast.

This repo provides a clean, modular setup. You’ll find instruction files for:
General Rails 8 conventions
Turbo + Stimulus
Tailwind
Solid Queue
Kamal
Importmaps
Hotwire Native

Use what you need, skip what you don’t.

Copilot Chat now supports repo-level instructions. That means you can set shared context for your whole project with no need to remind it what tech you’re using every time.

11.05.2025 16:25 πŸ‘ 0 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

Rails 8 introduced a lot: Kamal for deploys, Solid Queue for background jobs, SQLite support in production, Hotwire improvements, and more. Copilot’s default suggestions don’t keep up out of the box.

I pushed a repo with canonical Rails 8 Copilot Chat instructions for VS Code. If you’re working with the new Rails stack and using Copilot, this should save you some time.

Portanto o PS exige que um processo simples tenha de arrastar um mΓ­nimo de 3 meses, e o PSD propΓ΅e uma moΓ§Γ£o de confianΓ§a sem necessidade. No meio disto tudo a esmagadora maioria do parlamento escolhe ir a eleiΓ§Γ΅es sabendo que Γ© a ΓΊltima coisa que o paΓ­s precisa neste momento.

AD+IL would likely get an absolute majority if they ran together in an election.

It was never real. PS was horrible.

Educational scores (PISA) are terrible, the health system just got ranked the worst in Europe, immigration is out of control, etc.

the micro saas canon This article aims to compile some of the most influential resources in the micro-SaaS and indie hacking space.

Thanks Jason. I wanted to take this opportunity to tell you that I think your microconf YouTube video on building the ideal bootstrapped business is one of the best videos I’ve ever watched on the internet.

Any tips on building a programmatic meta/open graph image? The app is built with #rubyonrails if that is relevant.

Where do you stand on offering a free tier in B2C? I’m considering removing mine.

I did the same thing. In fact I used Grok to help me write the reason πŸ˜‚

The support for AfD was a crossing the Rubicon moment, and the recent anti NATO push is beyond the pale.

What a shame. I’m the target audience for electric cars, twitter, and would even end up buying Starlink in the future. πŸ€·β€β™‚οΈ

Nice. I’d love to have a proper biohacking/health dashboard. I feel like Apple Health is the closest and it’s quite limited. Data privacy is huge in this space though, not sure how it could be a web app.

Would love to know how they compare. I stopped using cursor a while back and wonder whether the updates have made it superior again.

Disposable Calculate disposable income & compare salaries across 30+ countries. Use our disposable income calculator to find equivalent salaries, tax rates, and cost of living worldwide.

Made some changes to the disposable income calculator: app.popadex.com/disposable_i...

Would love to get feedback if you have any.

Debugging. I find it difficult to troubleshoot when something doesn’t work as intended.

Over the course of a lifetime, this amounts to €500,000 in contributions to the state. Now the question is, can we really say the state is better at managing those half a million euros in providing for health, education, schooling and retirement than the individual?

Someone on an average wage in Spain - €1,000 net/month - pays 50% of their income in taxes, between social security and income tax. On top of that, they pay about 20% in indirect taxes on consumption.

Add a Fixture Dump Method for Development Tables Β· rails rails Β· Discussion #54145 Hi Rails team and community, I need functionality to generate fixtures from my development database to support some complex tests. In searching for solutions, I came across an interesting Stack Ove...

πŸš€ Rails devs, I'd like your thoughts!

I'm wondering if it's worth adding a fixture dump method to Rails for generating YAML fixtures directly from the dev DB. Handy for complex tests!

Read the full proposal and pitch in with your feedback & ideas!
