[Showoff Saturday] - Free & open source Stock Market Earnings Calendar

[Showoff Saturday] - Free & open source Stock Market Earnings Calendar

Hi, fellow devs

If you enjoy some stock trading after yelling at Claude/Codex all day, than we are in the same boat.

I like to keep an eye on earnings and major key indicators (always forget about those FOMC meetings), and I don't mind paying for some data, but Earnings Hub charging $20 for earnings calendar is too much.

Anyway, came up with my own with publicly available data.

Eventually thinking maybe, we can have some kind of open-source market tools, that user can configure on his own. Add whatever panels or data he/she wants to make it more personal.

What's done

- Earnings Calendar with earnings report
- Market Fear/Greed indicator
- Key market dates

Working:
- GexData
- Notifications (not sure if those are needed)

Would be glad to hear any suggestions

Cheers, Dan

A synoptic to help my dev and DevOps colleagues to understand what I've done

A synoptic to help my dev and DevOps colleagues to understand what I've done

I maintain an ongoing open-source project that reads OTel traces and flags I/O anti-patterns with a carbon estimate on top. The project started in March so it's about 8 months old.

From our conversations I could tell my dev and DevOps colleagues were missing a lot of what goes on under the hood since we deployed this in production 3-4 months ago so I built a synoptic to make it easier to understand.

It's an animated step-by-step walkthrough of the whole pipeline, from raw spans to a finding. Each stage maps to the actual module in the code. You can play it, step through with the arrow keys, change speed or switch between modes.

It took me over 3 months. And no it's not AI slop bc it's pretty useless when you ask it to turn complex code concepts (I/O anti-patterns and more) into clear diagrams. This only exists because I'd already written a ton of docs and drawn a lot of diagrams by hand so the synoptic grew out of that.

Some of the UI is inspired by a videogame I loved playing some years ago: Deus Ex: Mankind Divided.

The project is AGPL-3 so no fake open source and it's now hosted by the INR (Institut du Numérique Responsable), a French nonprofit working on the environmental and social impact of digital tech.

Thx for your attention :)

EDIT: huh, just noticed that the recording console is sticking out over the gif in the bottom left corner

EDIT 2: this is a public-interest project focused on sustainability with no greenwashing BS. It has serious public policy goals and solid scientific background: cutting wasted energy and the carbon emissions that come with it. If you're interested in helping with the ecological transition our world needs, feel free to come lend us a hand! :)

Procedural Almanac - A JavaScript library of procedural generation techniques with citations for every function

Procedural Almanac - A JavaScript library of procedural generation techniques with citations for every function

For week 2 of r/hacktoberfest I cataloged all the procedural generation techniques I could find online and put them into a library using vanilla JavaScript. Every technique in the library includes a citation and it has no dependencies. Works in the browser or Node.

The island in the GIF was generated using just the library.

GH repo: procedural-almanac

Demo: Random Island Generator

All stars on Github are appreciated!

My Mum and I made ItWord- a daily word game about uncommon words

My Mum and I made ItWord- a daily word game about uncommon words

I've been teaching my mum to code in Python, and a few months back she made a little CLI game where you have to enter words using the start and end characters from a single word. She named it ItWord, as in 'iterate word'.

I thought it was a cool idea. As a web developer, my first thought was that it'd be a nice daily word game format like Wordle. A lot of work and collaboration later, and here we are.

Please give it a try, and we're welcoming all feedback!

How do you think existing websites will be affected by the onslaught of AI assisted "vibe coded websites" in the market?

As above... Especially those which are more geared towards being startups at the present stage.

For context, I am currently overhauling my existing blog (that uses the WordPress framework and plugin ecosystem), and am looking to pivot it into having ecommerce and social network components.

As part of that sunk cost, I'm in no position to change course now.

But despite that... And not taking into account my situation, what can existing websites do (especially those which are startups and which are in the blog, community, ecommerce etc space) to ensure that they don't get overwhelmed by the AI vibe coded onslaught that is going to engulf the market and the internet?

What changed in my endless Three.js driving game after two weeks?

2 weeks ago I shared Planet-0 Drive, an endless low-poly driving game I’ve been building with Svelte and Three.js (my first hobby game that I build after work and around weekends).

First of all, thanks to everyone who tried it (300 of you) and shared feedback! I didn't expect to get so many useful suggestions, and I've spent a good part of the week working on improvements based on them.

While the game runs fine

Since then, I’ve been working on the parts around driving that make exploration feel more meaningful.

The biggest additions are:

  • Revampled the whole look and art direction of the game to be more appealing
  • More biome-specific scenery, including snowy pines, desert cacti, boulders, and reactive weather materials
  • A refined vehicle lineup with three vehicles: Rover, Drifter, and Hopper
  • A battery system with charging stations, power-cell pickups, low-power driving, and boost energy management
  • Cruise control for more relaxed driving, especially on mobile
  • Persistent driving records and platform-visit tracking
  • Shared room leaderboards for driving and exploration records
  • A first quest system, starting with collecting resources across the planet
  • Improved touch controls and a more compact mobile HUD

The project has gradually shifted from “how far can I push a procedural 3D world in the browser?” toward “how do I make spending time in that world enjoyable?”

That has led to some interesting design challanges. How much progression should an otherwise relaxing driving game have? How do you reward exploration without turning it into a checklist? Should there be more risk?

I’m still experimenting with those answers, but the game feels much closer to the idea I had originally: a place to drive around, discover things, set records, and occasionally meet other players.

You can try the latest version here:

https://planet0drive.vercel.app/

The project is still very much in early development, so I’d especially appreciate feedback on how the driving feels, how the progression comes across, and what would make you want to come back for another drive.

When you integrate with a big vendor API, do you build against most of the docs or just a few endpoints?

I’ve been thinking about how teams actually work through vendor API documentation, and I realized I don’t really know how it goes in practice.

On a small integration it’s usually simple. You pick the four or five endpoints you need and ignore the rest. But on bigger ones (ERP, banking, logistics, healthcare), it feels like the team ends up needing most of the document, and the work gets split between people by section.

For those of you who’ve done this recently:

Did you use a few endpoints or most of the vendor’s API? Did you split the sections between several engineers, or did one person own the whole integration? How did you keep everyone working from the same understanding of the docs, especially if they were a PDF or a messy wiki? If the vendor changed something later, how did you find out?

Mostly curious how common each situation is. Any war stories welcome.
