LabelMe v6.1 is out.

- SAM3 AI-Box: drag one box, get multiple shapes
- AI toolbar: 4 tools collapsed into 2 (AI-Points, AI-Box)
- Progress bar for model downloads
- Open one image, the whole folder loads

THE TOOL EVERY EMBEDDED DEV NEEDS TO KNOW ABOUT

no components. no wiring. no setup

→ https://t.co/XPnUBwGDec

wokwi is a browser simulator for arduino, esp32, and stm32 & it actually works

drop in sensors, hook up a display, add servos. run your code instantly...everything happens in the browser

1.7M+ projects built by the community, a simon says game, pong on a nano, a 32x32 LED tunnel... all simulated... all shareable

learning embedded systems or just need to prototype without touching hardware this is your shortcut

[Tom Dörr @tom_doerr]

Generates architecture diagrams from Terraform code

[George @odysseus0z]

TLDR: it is a cron job dispatching tickets from Linear to workers, each of which is a Ralph loop using a Linear comment as draft pad for persisted state.

Yes it is all you need.

Beautifully designed and minimal.

If you're a software engineer who wants to upskill in system design, read these 14 articles (links below):

[freeCodeCamp.org @freeCodeCamp]

You can now learn key cybersecurity concepts from Harvard professor Dr. David J. Malan right on the freeCodeCamp YouTube channel.

In this course, Dr. Malan teaches you how to secure your accounts, databases, software systems, and more.

You'll also learn how to protect your privacy and see examples of both high-level and low-level threats.

This repo just shrinks 60 million text chunks from 201 GB to just 6 GB without any loss in accuracy.

It’s a game-changer.

- 201 GB down to 6 GB (97% smaller).
- Zero cloud.
- Zero GPU. right on a standard laptop
100% private.

100% open-source

A graph-powered all-in-one RAG system!

RAG-Anything is a graph-driven, all-in-one multimodal document processing RAG system built on LightRAG.

It supports all content modalities within a single integrated framework.

100% open-source.

[ℏεsam @Hesamation]

I still believe this is the best repo to learn about ai agents HANDS ON. it focuses on key applications, from basic to advanced and covers MCP, RAG, multi-agents and so much more.

if you want to learn by coding (and you hate books) this is the way.

51K stars on GitHub! ✨
