Do AI-enabled companies need fewer people?
Revisits a year-old prediction that AI would create as many jobs as it automates, using startup headcount and funding data to show compute substituting for labor instead.
Dive Deep into Higher-Order Functions
Curated resource guide defining Higher-Order Functions as functions that take or return other functions, with map, filter and reduce as the everyday entry point into the concept.
Discurso de Engels diante do túmulo de Marx
Reprodução integral do elogio fúnebre de Engels a Marx em 1883, que atribui a ele a descoberta da lei do desenvolvimento histórico e da mais-valia, e o descreve como revolucionário antes de cientista.
Different Lineages within Wing Chun
Maps eight distinct Wing Chun lineages and traces how Leung Jan split one long form into Sil Lim Tao, Chum Kiu and Bil Jee to make the system faster to teach and learn.
Die My Love
Ficha da Wikipédia sobre o filme de Lynne Ramsay com Jennifer Lawrence e Robert Pattinson, adaptação do romance de Ariana Harwicz sobre depressão pós-parto e psicose numa fazenda de Montana.
Did contexts kill Phoenix?
Argues that Phoenix's contexts layer, meant to enforce domain-driven boundaries, raised the barrier to entry enough to slow the framework's adoption relative to Rails.
Dias -13 e 02: As perguntas movem o mundo
Relato de uma imersão de Kung Fu que liga o prêmio Ig Nobel, uma pergunta do Si Fu sobre arroz parboilizado numa viagem a Friburgo, e o ideograma 知 (Chi) recebido no nome Kung Fu.
Staff Engineer vs Engineering Manager
Argues Staff Engineers earn their value by operating across teams, not by covering for a manager's technical gaps, and breaks ownership into knowledge, mandate, and responsibility.
How Can Engineer Leaders Stay Technical?
A CTO explains how he keeps technical depth without coding daily, and the piece weighs that against the power asymmetry risk of a manager's technical opinion going unchallenged.
Beyond Staff Engineer
Alex Ewerlöf describes what Senior Staff Engineer changes from Staff Engineer: less hands-on code, more delegation, longer time horizons, and communication built for a 10x larger network.
Accountable vs Responsible
Distinguishes accountability from responsibility through RACI, military, and legal framings, then argues most organizations don't need the split unless there are real legal consequences at stake.
AI Is Forcing Us To Write Good Code
A six-person team enforces 100% code coverage, thoughtful file naming, and fast disposable dev environments because coding agents need the guardrails humans used to skip under deadline pressure.
Dev Barometer Q3 2025: AI-Driven Talent Meets Lagging Companies
BairesDev's first Dev Barometer survey of 1,129 developers finds they save 7.3 hours a week with AI and reinvest much of it in upskilling, while most employers remain stuck at early AI maturity.
Becoming a Professional Software Developer: Identity Over Skills
Applies James Clear's identity-based habits framework to software development: developers abandon best practices under deadline pressure not from lack of skill, but because the practice isn't tied to their self-image.
Understanding Pure Domain Modelling
Argues that domain experts default to describing their existing system rather than the real domain, and proposes asking 'what would you do without a system?' to get past that bias.
Design a Rate Limiter
Hello Interview's breakdown walks a system-design rate limiter from placement decisions through four limiting algorithms, landing on Token Bucket over Redis with a Lua script to close the race condition.
Democracia sem partido
Ensaio da Piseagrama percorre a origem dos partidos políticos, a crítica de Simone Weil e Max Weber a eles, e experimentos de democracia direta, delegativa e por sorteio como alternativas.
Don't Waste Your Back Pressure
Argues that agent leverage scales with the automated feedback ('back pressure') around them, like build systems, type checkers, and browser tools, not with the model alone.
Refactoring to Serverless: From Application to Automation
AWS engineers propose 'serverless refactoring': moving logic like event publishing out of application code and into automation code (CDK, Lambda Destinations) to separate business logic from topology.
Cursor debuts Composer and multi-agent suite in Cursor 2.0
Cursor 2.0 ships Composer, a coding model tuned for sub-30-second responses, alongside an agent-centric interface that runs multiple agents in parallel via git worktrees or remote machines.
The Illusion of the Illusion of Thinking
Anthropic and Open Philanthropy researchers argue that a widely cited 'reasoning collapse' study measured token limits and broken benchmarks, not a failure of model reasoning.
Continuous AI in software engineering
Sean Goedecke argues AI should be used like tests and types, continuously and automatically, not as an on-demand oracle a developer has to remember to consult.
Sustainable Building Effort Reaches New Heights With Wooden Skyscrapers
Mass timber lets architects build tall with manufactured wood instead of steel and concrete, cutting emissions but carrying open questions on fire, moisture, and real carbon accounting.
Confessions of a Millennial in Tech
Elena Verna names the feeling underneath the AI shift in tech as being permanently behind, and traces what happens to career value when execution skill gets automated.
From Microservices to Modular Monoliths
Argues that teams stuck in microservice hell should migrate back to modular monoliths, keeping modularity without distributed-system overhead.
LLMs reward expertise
The post argues that the main skill in prompting is domain knowledge. Expert users can steer LLMs harder, spot odd answers, and get more useful results than people who only know general prompting tips.
How I Find Problems to Solve as a Staff Engineer
Lalit Maganti says staff engineers find useful problems by absorbing day-to-day complaints, waiting for evidence to accumulate, and pressure-testing common shapes before building anything.
The Best Prioritization Is No Prioritization | Stay SaaSy
The piece argues that prioritization is usually a trap: frameworks are shaky, outcomes are hard to prove, and the process burns time better spent building faster or keeping teams focused within fixed domains.
The Antithesis Principle
The essay says useful observations have an outward lesson and an inward one: learn the tactic, but also remove the default in yourself that makes you dependent on it. The wise see both directions.
So, you want to be a content creator?
Elena Verna explains why she started creating content, how she grew on LinkedIn and Substack, what monetization and visibility changed, and why creator work brings both opportunity and stress.
Architecture Is a Game of Constraint Satisfaction
Gregor Hohpe argues architects keep designing around constraints (procurement lead times, hardware size, coupling costs) long after the constraint that justified them has quietly disappeared.
Every Layer of Review Makes You 10x Slower
Avery Pennarun argues AI coding speed doesn't fix engineering velocity because review layers, not typing speed, are the bottleneck, and draws on Deming's quality theory to argue for eliminating review stages, not stacking more of them.
China's AI-Powered Self-Driving Car Market Is Ahead of the U.S.
Government-backed infrastructure, deeper data access, and higher public trust in AI give China's autonomous vehicle industry a real lead over the fragmented, courtroom-driven U.S. approach.
How Did We Get So Obsessed with Streaks?
Anne Helen Petersen interviews game designer Adrian Hon on why most corporate gamification is bad by design: it replaces human judgment with fixed metrics and punishes people for needing rest.
CEOs Start Saying the Quiet Part Out Loud: AI Will Wipe Out Jobs
Ford's CEO predicts AI replaces half of white-collar work; Amazon, JPMorgan and Anthropic executives make similar bets in public for the first time, while OpenAI's COO pushes back.
Batalha de Aljubarrota
Como um exército português, em menor número, usou terreno escolhido e paliçadas para destroçar a cavalaria castelhana e francesa em 1385, consolidando D. João I como rei e a dinastia de Avis.
My New Angular Coding Style
Kevin Kreuzer documents the coding style his team converged on after rewriting a large codebase around Angular Signals: standalone by default, no lifecycle hooks, inject() over constructors, often no constructor at all.
Career Expert Warns Workers to Lie About 5 Specific Things During a Job Interview
Career coach Anna Papalia argues that softening five honest answers, five-year plans, why you're leaving, feelings about your boss, hobbies, job title, helps more than it hurts in interviews.
Why You Need Soft Skills as a Tech Lead
Anemari Fiser argues most technical-sounding problems Tech Leads face are actually people problems, using two real cases to make the point, and lists 7 soft skills to develop.
Avoiding the "Therapist" Trap as a Tech Lead
Anemari Fiser argues Tech Leads who default to solving every team problem burn out and become the sole point of failure; she proposes boundaries, self-check, and guiding instead of fixing.
