Background Recently I was migrating our databases from RDS to Snowflake Postgres . I was using pg_dump and pg_restore to take a dump of source database and restore into the new database. I ran this command on source database to see how large it is. SELECT…
TL;DR On September 10, 2026, Anthropic published "Detecting and countering misuse of AI: September 2026," its fourth threat-intelligence report, covering operations its team disrupted between December 2025 and August 2026 across seven harm areas, with a downloadable IOC set. The…
I am the founder of PromptUnit. This post first appeared on the PromptUnit blog , where it is kept up to date. If your OpenAI API cost feels too high, it usually is, and the fix is rarely "switch providers." OpenAI's current GPT-6 lineup alone spans a 100x price range: GPT-6…
Man, I've been tearing my hair out for the past few weeks. You know the drill – your staging environment, the place where everything should mostly work like production, but it occasionally just… dies. Not consistently, mind you. Just often enough to block deploys, frustrate the…
Beyond Deployment: What's Next for CrescoDB, Plus a Clearer Path to Getting Started Building a backend is only part of the work. You define your data, build your API, connect your application, test it, and eventually deploy it. Your application is live. Your users can access it.…
14:32 UTC. PagerDuty fires on the checkout service's error-rate alarm. Datadog shows the 502 rate on POST /checkout jumping from a baseline of 0.02% to 4.8%, right in the middle of a rolling deploy that had shipped a dozen times before without anyone noticing it. By 14:36 the…
Hey folks — I built A2Agent, a pay-as-you-go LLM API gateway similar to OpenRouter, but focused on Chinese open-weight models: DeepSeek / GLM / Kimi / Qwen / MiniMax One API key, OpenAI + Anthropic compatible Priced below official vendor rates, no top-up fee, credits don’t…
OOP Made Simple | CodeWithObaid — Day 2 Imagine you're building a library management system. Your application creates hundreds of Book objects. Each book has its own title, author, and price. But your application also needs to track how many Book objects have been created.…
Introduction Most advice on testing AI agents is about the answers, such as evals and golden datasets. Crash recovery needs its own test. If your agent runs as a durable workflow, a restart should resume the same run without repeating finished steps or side effects. You can…
AI code review went from demo joke to default pull-request infrastructure in about two years, and in 2026 the interesting question is no longer whether a bot should read your diff — it's which bot, and what it costs when the free tier ends. I read five vendors' own pricing pages…
Hey, beautiful internet people! I thought for my very first post and article, the topic should be how the internet actually works and what happens behind the scenes! I remember my early days on the internet, trying to figure out how programming even works and spending countless…
When a RAG answer is wrong, the reflex is often to raise top_k . More retrieved chunks feels safer. In production, it can do the opposite: the one useful passage gets surrounded by repeated, stale, or merely related text, while the model has less room to answer. A large context…
Here's a small habit that changed how I do code reviews: I never review unformatted code anymore. It started when I caught myself spending twenty minutes on a pull request that turned out to have exactly three lines of actual changes. The rest was mixed tabs and spaces,…
Author: Guangyi Zhao 1. Problem and background This article series runs under a standing rule: every draft gets reviewed by a different model before it can ship. The reviewer is told to hunt for factual errors, logical leaps, and overclaims; every comment must be resolved, one…
My obituary for programming Jeremy Scheff poignantly captures the key loss caused by coding agents for career programmers who enjoyed the puzzle of developing code: Programming turned into one of the greatest jobs you could imagine. You got paid to work on tricky little logic…
How Amoxi wires your services together at build time, how configuration reaches them, and the mistakes it catches before you deploy. In article 1, NoteController asked for a NoteService in its constructor and simply got one. This article shows how that works, and why it matters…
Have you ever needed to format a production SQL query containing customer records, parse a cURL command with an active Authorization: Bearer secret, or convert sensitive JSON data to TypeScript types? Most online formatters and conversion tools send your clipboard content to…
A transição da inteligência artificial puramente digital para o mundo tridimensional tangível — domínio consagrado como Physical AI — enfrenta um gargalo físico severo: ao contrário de assistentes conversacionais que toleram centenas de milissegundos para emitir uma frase,…
O construção de software e a implantação de sistemas cognitivos autônomos de tecnologia de cognição computacional de fronteira enfrentam um obstáculo estrutural compartilhado por toda a indústria: a volatilidade intrínseca da memória de contexto. Por mais extensas que sejam as…
A keyword can have high search volume, low competition, and still be a bad choice for your website. That's one problem I want to solve when building an SEO agent. It's easy to ask an agent to find keywords, check search volume, look at competitors, and return a list of…
Series: nosqlite devlog, Part 2 The first article was about the why. This one is where things get concrete. I remember the exact moment I opened a hex editor on a SQLite file for the first time. The first 16 bytes said 53 51 4C 69 74 65 20 66 6F 72 6D 61 74 20 33 00 . That…
TL;DR Ivanti Connect Secure is a VPN and remote-access appliance that a company runs at its own network edge, and CVE-2026-104935 is the identifier Ivanti assigned to an authentication bypass and a code-execution flaw in it. An attacker chained that bypass with a file write and…
The 30-second answer Every Python user in VS Code needs exactly three things working: Microsoft's Python extension (which now bundles the debugger), Pylance for completion and type-checking, and one formatter plus one linter. In 2026 that pair is Ruff (linter, with the official…
Imagine your company has 50 employees and 80 IT assets, including laptops, monitors, and smartphones. An employee leaves the organisation. HR confirms their departure, but IT cannot confirm whether their laptop was returned. The asset register still lists the employee as its…
Most developers who try Claude Code start the same way: open a repo, ask for a change, and get something that is almost right. The code compiles, but it uses the wrong logging library, skips the test convention your team agreed on, and opens a PR against the wrong branch. The…
One AI Model for Everything? A Practical Guide to Task-Based Model Routing When teams first add AI to an application, the architecture is usually simple. A request comes in. The application sends it to one model. The model returns a response. That approach is easy to build and…
(Note: This is the untold story behind the KAVLR launch. If you haven't read the main post, check it out here: https://dev.to/koda2026/iam-12-i-built-an-enterprise-ai-security-tool-on-a-150-phone-and-my-own-code-locked-me-out-m9b ) Building a product is not about writing the…
Stop Routing Reads to Primary: Building Causal Consistency in Java with Postgres LSN Tokens Falling back to your primary database for reads right after a mutation is a lazy architectural crutch that kills your write capacity at scale. In 2026, if you aren't using causal session…
