SQLAlchemy Hybrid Properties for Computed Tenant Metrics: Avoiding SELECT N+1 When Aggregating AI Feature Usage Across Multi-Tenant Hierarchies I burned three weeks of performance optimization on CitizenApp before realizing the problem wasn't our FastAPI endpoints or React rendering—it was a single
Training ML models has an environmental cost that most practitioners do not measure. A model trained during peak grid hours, when coal and gas plants are meeting high demand - can emit significantly more CO2 than the same model trained during off-peak hours when renewables dominate the grid. The car
Crucible v1.1.0 — The App-Building Kit Release 🚀 Most component libraries give you a black box: install a package, fight its API, and inherit a runtime dependency you can't fully control. Crucible takes the opposite approach — it generates the source code for components directly into your project.
TL;DR The friction you feel using the wrong AI tool isn't a prompting problem — every tool encodes a worldview about how work flows, and fighting that worldview produces worse results regardless of prompt quality. An ambient assistant thinks in cross-system context (email, calendar, CRM); a coding a
TL;DR A personal folder name leaked into public gallery output — not caught by standard PII checks because folder names sit in a gap that most safety checklists don't acknowledge. Anti-patterns are more valuable than patterns: the failure space for your specific context is more constrained and more
TL;DR Over 844,000 sites had implemented llms.txt by late 2025 — still under 1% of active websites, meaning early adoption is a differentiator; Cloudflare, Anthropic, Stripe, and Vercel all ship one. HTML is a lossy agent interface: every step from fetch to context extraction degrades content; llms.
The Logitech M850L is the brand's first mouse with a built-in cushioned palm rest and though it sounds gimmicky, it's actually useful. Here's how.
A week ago I shipped Prism's edge layer and wrote a blog post explaining what was good about it and what was wrong with it. The good: bad keys now get rejected from your nearest Cloudflare PoP, no Mumbai round-trip. The wrong: cache hits were still landing in 300–500 milliseconds because the cache i
TL;DR: Claude Code's ANTHROPIC_BASE_URL env var lets you redirect every request to any compatible backend in one shell line. Almost no one does it, but it unlocks caching, rate-limit pooling, multi-vendor routing, audit logging, and billing routing without rewriting any code. Here's the 2-line setup
Introduction: Hidden Costs in CI/CD Pipelines Every day, we deploy dozens, sometimes hundreds, of times. The faster and smoother this process, the more efficiently teams work. At the heart of CI/CD pipelines are build operations. However, these builds, especially in large projects, can consume signi
This is a submission for the GitHub Finish-Up-A-Thon Challenge Note: AI is currently a Hot Topic in the developer space. I recommend reading this post in full before commenting. The dataset being used does not come from dev.to, so expect the AI model to be inaccurate. This is to showcase a tool that
In 2017 I was maintaining a Node.js ecommerce server when a new project landed on my desk — an IoT platform for vehicle tracking devices. Thousands of devices, transmitting data continuously, with clients expecting real-time visibility into what the devices were reporting. The Node.js server started
Optimizing Lucene Indexing Performance for Large-Scale Data Pipelines by Prithvi S – Staff Software Engineer at Cloudera In modern data‑intensive applications, Lucene is often the engine behind log analytics, click‑stream processing, and telemetry ingestion pipelines. When you are ingesting millions
Repurposing an old laptop for self-hosting can save you money and provide a more powerful platform than a Raspberry Pi.
A new post on Google’s Chromium blog shares the results of the latest Chrome performance benchmarks, including record scores on tests running on an M5 MacBook Pro. Here are the details. more…
Launching a fast, secure, and scalable website no longer requires thousands in upfront server costs or dedicated DevOps teams. As of 2026, AWS powers 32% of the global public cloud market, offering flexible hosting options for every use case: from a 1-page personal portfolio to a high-traffic enterp
Pipeline & Prompts | Byte size guides on DevOps, Cloud and AI When I first started working in Cloud and Infrastructure, I assumed most servers ran Windows — because that's what I grew up using on my laptop. Then I got access to my first cloud environment and was greeted with a black screen, a blinki
Email is one of those things that's genuinely hard to test. It goes out through an SMTP server, lands in a real inbox, and you have no programmatic way to check what arrived. So most teams either test it manually or just assert that sendEmail() was called and call it done. Neither tells you if the s
I'm a junior SRE during the day. For the last few months I've spent nights and weekends building ResumeSnap, a tool that takes your experience plus a job posting and writes a resume tuned to that role in about a minute. Six people have paid for it so far. That's real money from strangers who found i
Spoiler: the machine was fine. My assumptions were not. You will try to SSH into your ZimaCube Pro. It will refuse. Not because of permissions, not because of a firewall. Because SSH is simply off. ssh zimacube-pro ssh: connect to host zimacube-pro port 22: Connection refused Go to your ZimaOS web U
