I can't remember the last time I got excited about a fan. Normally, I just buy whatever Vornado or Dreo model fits my budget, but that was before I started testing the battery-powered Standing Circulator Fan from SwitchBot. As the name indicates, the SwitchBot fan is a 3D circulator - a fancy way of saying […]

Want an LLM to know your private docs or this week's facts? You have two very different options — RAG and fine-tuning — and people constantly pick the wrong one. The rule is simple: facts → RAG, behaviour → fine-tune. 🧩 Pick a scenario, see which wins: https://dev48v.infy.uk/ai/days/day10-finetune-vs-rag.html RAG — give it notes at question time answer = llm ( retrieve ( question ) + question ); // open-book, weights unchanged Your data st...

A chatbot answers in one shot. An AI agent runs in a loop, uses tools, and acts — Thought → Action → Observation → repeat — until the job's done. Watch one solve a multi-step task by calling a calculator and a search. 🤖 Run the agent: https://dev48v.infy.uk/ai/days/day11-agents.html Agent = LLM + tools + a loop You describe tools to the model (name, purpose, arguments). It can't divide big numbers reliably or know today's data — but it CAN decide "call the calculator with ...

A real production incident, what the error actually meant, and the fix that stopped it from happening again. Photo by Chris Ried on Unsplash Some bugs are polite. They fail the same way every time, on your machine, with a clean stack trace pointing at the exact line. You fix them before lunch. This was not one of those bugs. This one only appeared in production, only under concurrent load, and only sometimes. The error code, DB2 SQLCODE -811 , is one of those messages that l...

Every modern web app wants to be "smart" about location. Show prices in the right currency. Default to the user's language. Calculate shipping. Block suspicious traffic. But there's one problem: the only built-in browser API for location requires a permission prompt that users dismiss more often than they accept. In this guide, I'll walk through how to detect a visitor's approximate location instantly and silently — without ever showing a permission dialog — using IP geolocation APIs. ...

Rate limiting an authenticated API is straightforward — you have a user ID, you track requests per user, you throttle when they exceed limits. Rate limiting an anonymous API is a different problem entirely. No user ID means you're working with proxies for identity: IP address, device fingerprint, behavioral signals. Each has weaknesses. Here's how to layer them effectively, which is exactly the challenge we solved building free AI image generator no sign up . Why Anonymous Ra...

Most agent architectures are quietly broken. They look great in a demo — single turn, clean task, instant response — and then fall apart the moment you ask them to do anything real. Like process a week of insurance claims. Or run a multi-day sales sequence. Or reconcile data across systems that don't share a clock. The reason is simple, and nobody talks about it: most agents are stateless under the hood. They reconstruct context from scratch on every interaction. The reasoning chain that ma...

When researchers paste DNA sequences into online tools, they rarely consider where that data goes. Yet a single gene sequence could represent months of lab work, unpublished findings, or even patent-pending discoveries. This is why I believe browser-based bioinformatics tools should be built with privacy-by-design principles — processing everything client-side whenever possible. The Problem with Cloud-Based Bioinformatics Most bioinformatics platforms follow a familiar pattern:...

I was doing AI-assisted coding inside a terminal session. The AI kept modifying files, but I had no way to view those changes in the same window — I had to switch apps, switch context, come back. Every loop through the cycle was an interruption. What I wanted was simple: the terminal and the AI and the files, all in the same place, without the context-switching. So I built it. That's the origin of aitm. The version 1.0 is that thing, shipped. The design choice: participant, not...

A few days ago, I was browsing through an online bookstore to purchase some books. While placing the order, something remarkable struck me — every major technology I used in the process was of Indian origin. This realization inspired me to reflect on how far India has come in building its own robust digital ecosystem, especially when it comes to digital payments. Let me take you through the step-by-step journey of that simple online order and unpack the fully Indian tech stack powering...

For the last decade, the workflow for Business Intelligence hasn't changed much: A business stakeholder asks a question, a Data Engineer writes the ad-hoc SQL, and a dashboard is built. But as data scales to the petabyte level, this reactive cycle creates massive bottlenecks. What if business users could just chat directly with the database? Enter BigQuery Conversational Analytics . Google Cloud has effectively turned the traditional data warehouse into an active participant. By leveragin...

{ Abhilash Kumar Bhattaram : Follow on LinkedIn } DR : The grey zone Many Chief Technology Officers (CTOs) feel a false sense of security once they migrate to the cloud and turn on managed Disaster Recovery (DR) services. "With a few clicks, your entire stack is replicated across regions." But there is a hidden blindspot in cloud-managed DR. While Oracle Cloud Infrastructure (OCI) Full Stack DR does an incredible job of orchestrating infrastructure failover, it crea...

French serial entrepreneur and open-source legend Jean-Baptiste Kempf has been building Kyber, an infrastructure layer to control remote devices in real time.

Most agents drag their entire past into every turn. A better default: keep a thin index of what was said hot, and fetch only the few turns you actually need — intact, on demand. Code: github.com/NirajPandey05/jit_context There is a quiet assumption baked into how most agents handle memory: that more context is safer than less. If the model might need something, put it in the window. The conversation grows, every prior turn rides along on every new request, and we trust the model to...

How we extract, translate, and reconstruct entire ebooks with Python while preserving every detail At LectuLibre, we built a service that translates entire books using large language models. Our users upload EPUB files, and our backend pipeline parses them, extracts the text, sends it to an LLM for translation, and then rebuilds the EPUB with the translated content—all while preserving the original formatting, images, and metadata. This sounded straightforward until we looked inside a real E...

Financial advisors have a dirty secret: they spend almost half their working hours not advising anyone. The culprit? Compliance documentation. After every client meeting, advisors must document what was discussed, what was recommended, whether those recommendations were suitable, and whether they followed FINRA and SEC rules — all in a format their CRM can ingest. A 45-minute meeting routinely generates 2 hours of paperwork. I built an open-source tool that does it in about 3 minutes. H...

Đối với một developer, trackpad không chỉ là thiết bị điều hướng mà còn là công cụ tối ưu hóa workflow. Khi làm việc với các IDE nặng như VS Code hay IntelliJ, khả năng phản hồi của trackpad quyết định tốc độ xử lý tác vụ. Trong bài so sánh giữa ROG Zephyrus G14 GA403 hay MSI Creator 16 AI? Đâu là lựa chọn cho sáng tạo chuyên nghiệp? , trải nghiệm trackpad là một điểm nhấn quan trọng. Trải nghiệm cử chỉ và độ chính xác trong lập trình Khi làm việc với code, các cử chỉ như ch...
