[Other] Show HN: I built a website to visualize company financial data Hi HN, I built a website myfinsight.com that aims to make complicated company financials easy to understand.<p>The problem: The go-to place for financial data such as revenue, sales, net income is Yahoo finance. However, their data is usually wrong and very limited. The numbers are hard to digest to get insight quickly. There are also numerous websites that provide much better data for a very expensive monthly fee.<p>Solution: a website that provides free diagrams and charts that visualize important financial data, such as income growth rate by date, revenue breakdown etc. It is free because the financial data process is highly automated without manual input and correction.<p>I used to send the finance infographics to friends and family. I found it easier just to make a website and they can grab the data from it.<p>Next steps: there is a long tail of companies that don’t file their reports correctly. I am trying to make it more accurate somehow, and maybe add live stock prices to the website. I am also looking for feedback! Please play around with it and let me know if something is wrong.

[CLI Tool] Show HN: Easily reduce GitHub Actions costs with Ubuntu-slim migration Hi, HN!<p>I&#x27;ve been running GitHub Actions workflows for a while, and when GitHub announced ubuntu-slim runners as a cheaper alternative to ubuntu-latest, I wanted to migrate. (Blog: <a href="https:&#x2F;&#x2F;github.blog&#x2F;changelog&#x2F;2025-10-28-1-vcpu-linux-runner-now-available-in-github-actions-in-public-preview&#x2F;" rel="nofollow">https:&#x2F;&#x2F;github.blog&#x2F;changelog&#x2F;2025-10-28-1-vcpu-linux-runner...</a>)<p>But manually checking which workflows can safely migrate is tedious—you need to check for Docker usage, services, containers, execution times, and missing commands.<p>So I built gh-slimify, a GitHub CLI extension that automates this. It scans your workflows, detects migration candidates, checks for incompatible patterns, identifies missing commands, and can safely update workflows with one command.<p>Try it: gh extension install fchimpan&#x2F;gh-slimify gh slimfy # Scan workflows gh slimfy fix # Update safe jobs only<p>Open source (MIT). I&#x27;d love feedback on how to improve it or what edge cases I might have missed.
