Introdução Angular 22 chegou em março de 2026 consolidando uma estratégia clara de reatividade e modernização da arquitetura framework. Se você trabalha com projetos corporativos de larga escala ou está decidindo entre Angular e React, este é o momento certo para entender por que Angular mudou radic
Disclaimer Este texto foi inicialmente concebido pela IA Generativa em função da transcrição de um vídeo do Dev Eficiente. Se preferir acompanhar por vídeo, é só dar o play. Introdução Quanta configuração um agente de código realmente precisa para gerar bom código? Essa é a pergunta que eu venho ten
Tracking Google rankings sounds simple at first. You have a keyword. You search it on Google. You check where your website appears. That works if you only have one keyword. But once you need to track 50, 500, or 5,000 keywords across different countries, cities, languages, or devices, manual checkin
Most developers generate images like this: const html = ` ${post.title} ${post.author} · ${post.date} `; This works — until it doesn't. Special characters break the HTML (&, in titles) The template grows and the string becomes harder to maintain Reusing the same template across environments gets mes
Hey Dev, I built the first tool that gives developers hard spending limits inside AI agents — instead of reactive account-level caps that only kick in after the money is already spent. Most platforms let you set a monthly budget and then email you after you’ve been overcharged. Valta checks the budg
Field test status: diagnostic pass completed; upstream direction pending. This one is different from the merged patch reports. The Electron case produced a narrow draft repair and a focused regression test, but it did not land as-is. Maintainer review raised a security-boundary concern, and the repa
Recursion trips up more Python developers in technical interviews than almost any other concept. Not because recursion itself is complicated, but because most people try to hold the entire call stack in their head at once. You do not need to hold it all in your head. You need a trace table. A trace
Have you ever wondered how websites, mobile apps, video games, or even calculators work? Behind all of these technologies is something called coding. If you are completely new to programming, terms like variables, functions, loops, and algorithms might sound confusing. The good news is that coding i
Last updated: June 2026 Fider is the open-source feedback board a lot of teams reach for once Canny or UserVoice sends the renewal invoice. Public roadmap, feature voting, status updates, your own subdomain - the stuff you actually need to run "tell us what to build next," without the SaaS price tag
Numerical integration is one of the central tools of scientific computing. Whenever a physical, biological, chemical, mechanical, electrical, or control system is modeled by differential equations, the next practical question is usually not only “what is the equation?” but also “which numerical meth

In our ongoing SIG Spotlight series, we shine a light on the groups that keep the Kubernetes project moving forward. This time, we catch up with SIG Storage, the group responsible for persistent data, volume management, and the interfaces that connect Kubernetes workloads to the storage systems bene
A performance budget is a set of agreed-upon thresholds that your application must not exceed — bundle size, load time, image weight, API latency. Without a budget, performance degrades incrementally with every feature added. This guide covers how to define, measure, and enforce performance budgets
I spent three hours the other day staring at a regular expression that was supposed to extract phone numbers from a pile of scraped HTML. It worked for 70% of the cases, then failed spectacularly on the rest. The formatting was everything you'd expect from the wild west of the web: (555) 123-4567, 5

Most agents I build start life the same way: capable, fast, and completely amnesiac. They have no opinions, no voice, and they forget everything the moment the session ends. They're a search engine with extra steps. After rebuilding the same scaffolding for the Nth time, I converged on a small set o
Last month's Anthropic bill hit $312. Sixty percent of it traced back to a single 6-hour window when I was doing an in-place Vectorize index rebuild. Here's the part I didn't expect: the rebuild didn't throw errors. Queries returned results, scores just quietly dropped from 0.78 to 0.61. My agent in
The Model Context Protocol (MCP): what it is and how to build a server Your team's LLM-powered application talks to a search index through one custom integration, a code repository through another, a Postgres database through a chain of LangChain tools, and a file system through raw Python I/O calls
Python is known for being simple, readable, and developer-friendly. One of its biggest advantages is automatic memory management, which means developers usually do not need to manually allocate or release memory. However, this does not mean Python applications are completely safe from memory leaks.
A team ships a support triage agent on a Friday. It works beautifully for two weeks — reads inbound mail, drafts replies, files tickets. Then a prompt regression slips through a deploy, the agent misclassifies a thread, and it starts replying to everything in sight. Nobody notices for hours because
