In June, we experienced six incidents that resulted in degraded performance across GitHub services. The post GitHub availability report: June 2026 appeared first on The GitHub Blog .
Elon Musk's tech company released the newest version of Grok on Wednesday, promising a cheaper, more efficient alternative to other powerful AI models.
TLDR: Do you have a pattern or structure for doing long-lived research or non-coding projects using LLMs? I was kind of inspired by this hacker news article where someone collected data to solve their fatigue problem: https://news.ycombinator.com/item?id=48605117 A similar but smaller I did was to collect nut-free restaurants to eat in Chicago. So I had articles, reviews, emails, phone calls, all sorts of stuff. I found it very easy to just use Copilot as my interface and I just data into it ove
This developer didn't expect his side project to grow to 300,000 users, but people love Roost because it's an alternative to an always-on, fast-paced online culture.
General Intuition is betting millions of hours of video game data can train the foundation models for physical AI, making it easier to build smarter robots with minimal real-world data.
PC shipments are falling, but revenue for manufacturers is still rising.
Both vulnerabilities allow untrusted users to gain root privileges.
The Steam Machine isn't worth the price that Valve is asking.
Have you ever wondered how AI engineers fine-tune and align large language models? Under the hood, they run Supervised Fine-Tuning (SFT), optimize parameters using direct preference gradients (DPO), filter out low-quality pre-training corpuses (Pruning), and mitigate catastrophic drifts. To help you visualize how LLM alignment and parameter optimization work in a highly strategic way, I built a cyberpunk card battler inspired by Gwent: 🤖 Epoch Duel: Cyberpunk LLM Alignment Battle Play in Fullscreen Mode (if the embed sizing is tight) 🛠️ Tune Your Model Parameters Your mission as an alignment engineer is to play optimizer cards to outscore the adversarial baseline AI across 3 training Epochs: ⚙️ Logic & Coding: Run SFT code snippets, compile theorem provers, and deploy Python scripts to build your coding benchmark scores. 📖 Language & Speech: Train on multilingual datasets and summarization corpuses to maximize reading comprehension. 🛡️ Safety & Alignment: Implement red-team safeguards, configure RLHF preference pairs, and run DPO tuning to protect your model's outputs. ⚡ regularizers & Drifts: Deploy Regularization cards like Gradient Clipping (Scorch) and Model Pruning to destroy anomalies, or exploit Anomalous Drifts to collapse the AI's rows. 🧬 Playable ML Concepts Explained Here is how the card battle mechanics map to production machine learning pipelines: 1. ✂️ Model Pruning (Weight Compression) In-Game: Playing the Model Pruning card triggers a glitchy dissolution animation that purges the lowest-value card from the targeted board row, cleaning up noise. 💾 The Real-World Counterpart Model Pruning removes unimportant weights (often those closest to zero) from a trained neural network. It shrinks the memory footprint of the model, allowing it to run faster on edge devices. ⚠️ How it affects LLMs By stripping out low-impact weights, pruning compresses models by 30-50% with minimal loss in benchmark accuracy, making deployment significantly cheaper. 2. 🔀 DPO vs RL
AI coding agents are becoming good enough to touch real codebases. They can refactor files, write tests, change architecture, move logic around, and sometimes modify more code in ten minutes than a human would in an afternoon. That is powerful. But it creates a new debugging problem. Git can tell you what changed . When an AI agent was involved, you often need to know something deeper: Why did this change happen? Which prompt caused this line? Which model produced it? What files did the agent read before writing it? What later changes depended on this agent action? That is the problem I wanted to solve with Causari . Causari is a local CLI for intent-addressable code . It records AI agent actions as causal events: prompts, models, reads, writes, diffs, reasoning, cost, and relationships between actions. The goal is simple: Git tracks bytes. Causari tracks intent and causality. Repository: https://github.com/croviatrust/causari Website: https://causari.dev The problem When a human developer changes code, there is usually some context. A commit message. A pull request. A ticket. A discussion. A design decision. With AI coding agents, the workflow is different. You ask something like this: Refactor the auth flow and add JWT refresh logic. The agent reads files, makes assumptions, writes code, maybe fixes tests, maybe changes something unrelated, then moves on. At the end, you have a diff. But the diff does not tell the full story. A suspicious line appears in auth.ts . Git can show when the line appeared. But Git cannot answer: which prompt produced this exact line? what completion did it come from? did the agent read the right files first? was this part of the original request or an accidental side effect? if I revert this, what downstream work am I also undoing? That gap becomes bigger as agents become more autonomous. The more work agents do, the more we need provenance. Not only code provenance. Intent provenance. The idea: intent-addressable code Causari treats an
As part of Microsoft's big Xbox "reset," which includes layoffs affecting 3,200 staffers, jettisoning studios, and shifting investments to focus on "higher priority projects," Obsidian Entertainment is changing its plans. The studio, behind games like Grounded and The Outer Worlds, is starting work on a new Fallout title and has canceled "multiple projects," including a […]
I'm building TrainWiz , a Flutter app that turns real exercise into a pet-raising game: you do squats or push-ups, your phone counts the reps, and a little creature levels up and evolves. The core technical problem sounds trivial and absolutely is not: count reps from the camera, on-device, without uploading a single frame. Here's what broke along the way, and what finally worked. Why on-device Two reasons: privacy and latency. A fitness camera that streams your body to a server is a non-starter for most people, and rep feedback has to feel instant or the whole "game" loop dies. So everything runs locally with tflite_flutter + an on-device pose model — no footage ever leaves the phone. Naive attempt #1: joint-angle thresholds The obvious approach: track the knee angle, count a rep when it dips below X° and comes back up. // looks fine in a demo, dies in the real world final kneeAngle = angleBetween ( hip , knee , ankle ); if ( ! _down && kneeAngle < 100 ) _down = true ; if ( _down && kneeAngle > 160 ) { reps ++ ; _down = false ; } It demos beautifully. Then real users prop the phone on the floor, stand at an angle, and it falls apart. The trap: a phone camera gives you 2D pose. A "120° knee angle" flattens completely depending on where the camera sits — the same squat reads as 90° or 150° purely from perspective. Lifting to 3D via the model's z doesn't save you either; monocular z is noisy enough that the angle jitters across your threshold and double-counts. Naive attempt #2: a "body-line" gate Next idea: figure out which exercise you're doing so I can pick the right signal. Standing (squat) vs. horizontal (push-up) should be easy — just check if shoulder, hip and heel form a straight line, right? Wrong, again for the 2D reason. In a real push-up shot from the front-corner, shoulder–hip–heel are not collinear on the image plane — perspective bends them. I gated push-up counting on "body is a straight line" and it would just... stop counting mid-set. Nothing is more
