OpenAI details Codex Windows sandbox architecture, showing how SIDs, ACLs, restricted tokens, and dedicated sandbox accounts enable safe execution of autonomous coding tasks. The design balances isolation with real developer workflows and shows how OS security primitives must be composed for AI agen
Our fitness kit's iOS build used to take 14 minutes on CI. After upgrading to Expo SDK 54, it takes 4. That's not a CI optimisation. We didn't add parallel runners or bump the machine size. We just landed on the SDK that ships precompiled XCFrameworks by default. Same code, same build profile, same
Most CLAUDE.md files we see are too long. Five thousand lines, six thousand. Every team rule, every legacy comment, every "I once tried this and it didn't work" footnote. The author feels productive writing them. The model reads the first 800 lines and ignores the rest. There's a known ceiling, and
Cursor 3 ships a thing called "Build in Parallel." The pitch is straightforward: instead of executing a plan step by step, Composer identifies which steps are independent and runs them as concurrent subagents. It's a real shift. And it changes what a useful production template has to look like — bec
Technical Reconstruction: Interfaces, Traits, and Dynamic Method Dispatch Main Thesis: Understanding the 'why' behind Interfaces, Traits, and Dynamic Method Dispatch is crucial for self-taught developers to transition from building functional code to writing scalable, maintainable, and efficient sof
This is a submission for the GitHub Finish-Up-A-Thon Challenge Cijene ("Prices") is Croatia's premier open-source grocery price tracker and shopping cart optimizer, designed to help families fight double-digit inflation. It began as a hackathon prototype that won first place at a national software d
If you run paid acquisition on Meta for landing pages, you already know the problem: iOS 14.5 gutted browser-side tracking. Meta's answer is the Conversions API (CAPI) — server-side event delivery that bypasses ad blockers and browser restrictions. But "just add CAPI" is about 20% of the actual work
This is a submission for the GitHub Finish-Up-A-Thon Challenge This is my submission for the GitHub Finish-Up-A-Thon Challenge. The idea behind this challenge really hit home for me: finally finish what you started. AI-powered space operations intelligence platform that can investigate orbital risk,
3am page: GPU training pipeline missed its SLA. Datadog shows 95% GPU utilization. nvidia-smi agrees. Everything looks green, but the job is 3x slower than expected. Zero tools to diagnose this. eBPF kernel tracing produces causal chains in 60 seconds: the host CPU was fighting with DataLoader worke
I cancelled $123/month in subscriptions after finding these repos. Here's the list. Stars: 130K+ | Replaces: $20-200/mo in AI API costs Run Llama, Mistral, Gemma locally. No API keys, no usage limits, no data leaving your machine. brew install ollama && ollama run llama3.2 Stars: 70K+ | Replaces: Za
AI Gateway now features real-time spend limits to prevent runaway token bills across multiple AI providers. By integrating with Cloudflare Access, companies can use identity-driven budgets and policies.
Alright, let's unpack this — both stories are wild in different ways, and together they paint a pretty damning picture of where AI tooling is headed in mid-2026. Yeah, this is real, and it's as ironic as it sounds. What's happening: Microsoft — the company that owns GitHub, invested ~$13 billion in
Once relegated to R&D labs for visual mockups and rapid prototyping, 3D printing is undergoing a massive paradigm shift. As we head into 2025 and 2026, global manufacturing industries are transitioning from rapid prototyping to the production of end-use, mission-critical parts. Additive Manufacturin
It's 2026. You've watched the language wars get louder for another year. Rust keeps eating systems work. TypeScript keeps eating everything that touches a browser. Python keeps eating the AI tooling layer. Somewhere in the middle, quietly, Go keeps running the backend services that pay everyone's sa
Be honest—how many times a week do you just Google "JSON formatter" or "MD5 hash"? For me, it's practically a daily habit. We usually just click the first link, paste our stuff, get what we need, and move on. But recently, I had a wake-up call. I was debugging a messy API integration and copied a ma
Any cloud people here? 👀 I've got basically 0 cloud knowledge, but a hackathon I'm looking at seems to need someone who actually knows what they're doing in that space 😭 If you're into cloud, interested in hackathons, and don't mind teaming up with someone who asks way too many questions, lemme kn
When I first started preparing for the Certified Kubernetes Administrator (CKA) exam, my primary goal was simple: Pass the certification and strengthen my Kubernetes fundamentals. Over time, I learned a lot about: Pods Deployments Networking Storage Scheduling Troubleshooting Cluster Administration
Same task. Same machine. Same models. Two runs. $1.96 vs $0.74. The difference wasn't prompt engineering. Wasn't a cheaper model. Wasn't a better GPU. It was whether Claude Code worked alone or handed off to an AI agent (Neo) before touching a single file. Here's what actually happened. Benchmark tw
When I started learning programming, I followed the obvious path: Take courses → Finish them → Become a good developer. It made perfect sense. There were thousands of high-quality courses taught by experienced developers. I watched videos, took detailed notes, coded along, and felt productive with e
I needed a timeline for a reporting feature. Not just something interactive in the browser, but something that could also be rendered server-side and exported (PDFs, images, etc). It also needed to show dependencies between items, not just a flat set of events. Seemed straightforward enough. vis.js
