Why I'm Ditching F# + Giraffe For Falco For Building WebApps
The author says Giraffe is still solid, but Falco’s simpler API, similar performance, and recent updates made it the new default for CloudSeed and future F# web apps.
Raphaël Millière on the Limits of Deep Learning and AI x-risk Skepticism
Raphaël Millière argues that current scaling results do not justify claims about human general intelligence, and that today’s models still fall short of broad generalization and human-level compositionality.
Interview Question: how do you ensure you only virus scan once?
The article argues for interview questions based on real work, using a file-upload and virus-scanning scenario to test system design, performance, fault tolerance, and UX rather than rote algorithms.
Bringing SOLID to Elixir
The article adapts SOLID to Elixir with modules and behaviours, showing how SRP, OCP, LSP, ISP, and DIP can support maintainable, extensible, testable functional code.
2008 Redux: The Great Tech Reset
The post argues that the 2008 crisis forced startups into discipline, lean execution, customer validation, and resilience, and that those habits shaped companies that later became giants.
Entrepreneur Interview Series - A Sit-Down with Screenius genius co-founder Seth Cohen

5 Reasons the Android Tablet is Better than the iPad
The post argues that Android tablets can challenge the iPad by offering more size options, a less disruptive notification system, more cameras, replaceable batteries, and no need to sync through a computer.
Carpal Tunnel Syndrome
The post describes the author’s wrist and hand pain, worries about CTS, a costly ergonomic keyboard search, and a medical overview of what carpal tunnel syndrome is, its symptoms, causes, and workplace prevention measures.
Agentic Design Systems in 2026
Brad Frost argues that design systems combined with AI can support collaborative product work, letting non-technical teammates shape features while AI stays constrained by production-grade components and standards.
The PERFECT Code Review: How to Reduce Cognitive Load While Improving Quality
The article argues that code review should be structured around business value, edge cases, reliability, design, tests, clarity, and taste to reduce cognitive load and make reviews more effective.
Kick Off Your Morning with This 15-Minute Full Body Routine
This short routine is meant for a quick morning start, with 10 exercises that work the core, lower body, back, arms, shoulders, and endurance in about 15 minutes.
3 Questions You Can Ask for Greater Personal Productivity
The page argues that asking yourself three questions can shape productivity: a specific Magic Question, a themed day, and Franklin’s daily reflection on what good you did.
The 5 Rules of Effective Component-Driven Development
The article explains component-driven development as a way to build reusable, specialized, context-agnostic, isolated, and replaceable parts that improve flexibility, maintenance, teamwork, estimates, and costs.
How to run a transparent startup
PostHog argues that internal transparency helps startups build trust, autonomy, accountability, and faster asynchronous work, especially in remote teams, and suggests sharing more by default.
How not to be boring
PostHog argues that brand and website shape how people judge a startup, and that being specific, transparent, and intentionally opinionated can attract the right users while turning away the wrong ones.
The Impossible Backhand
The post argues that AI hits a structural quality ceiling, so deep domain expertise becomes more valuable, not less. Human-AI collaboration works best when people can spot where models are confidently wrong.
How to Lead Your Team when the House Is on Fire
The article adapts wartime leadership to engineering management: narrow priorities, remove blockers, preserve morale, hire for autonomy, handle performance issues clearly, and keep supporting individual growth and your own capacity.
Overengineered #001: Hello World
The post rebuilds Hello World as a distributed Elixir app: UDP broadcast finds nodes on startup, and node monitoring triggers greetings when peers join the cluster.
Distributed PubSub in Elixir
The article builds a local PubSub with Registry, then extends it to a clustered setup with pg and libcluster so each node relays messages to local subscribers.
How expensive is exception throwing in .NET 9?
BenchmarkDotNet measurements on .NET 9 show that try-catch without thrown exceptions has almost no overhead, while throwing and catching an exception adds measurable time and allocation.
Inking — Part 3 of 3
Final installment of a three-part series on inking, with a one-hour demonstration focused on mark-making, brush dynamics, and the thinking behind the choices on the page.
Inking — Part 2 of 3
Paolo Rivera explains the materials and handling choices behind his inking workflow: ink, white-out, paper, brushes, alternatives, and brush washing. He stresses control, consistency, and testing.
Inking — Part 1 of 3
Paolo Rivera explains why inking remains necessary in comics, how it distills what matters in an image, and how limited values can sharpen composition and clarity.
Weird Science
Paolo Rivera describes a tribute cover for an EC Comics show, modeled on Wallace Wood, and explains his digital-to-ink workflow, from rough layouts and blue-line print to final inking.
Mathematician Yitang Zhang Claims to Have Proven Riemann Hypothesis Problem
The article says Yitang Zhang reported proving the Landau-Siegel zeros theory, a result tied to the Riemann hypothesis, but the claim was not yet verified and a paper was expected in November.
Neo Symbolic Capitalism
The text argues that social media turns reputation into symbolic capital, rewarding speed, narrative control, and attention. Companies and founders use media tactics to stay central in the feed.
Software Design is Knowledge Building
The article argues that software design is about building a shared theory of the system. When the original designer leaves, the team loses the mental model needed to modify the code safely.
A Note on Essential Complexity
The post argues that software engineers should think beyond accidental versus essential complexity. By questioning requirements and shaping users and organizations, they can sometimes reduce complexity by changing the problem itself.
Exercise may not be the key to living longer — it might even be aging you faster
A Finnish twin study found that lower activity was linked to higher mortality, but the link shrank after adjusting for lifestyle factors, and very high activity was tied to slightly faster biological aging.
Novo app propõe devassar a vida criminal do seu boy por menos de R$10
O Plinq vende buscas em bases públicas para ajudar mulheres a avaliar se um pretendente é seguro, usando processos e outros dados para classificar perfis como Green Flag ou Red Flag.
Evolving my ergonomic setup (or, my laptop with extra steps)
The author reviews four iterations of a portable ergonomic laptop setup, showing how each prototype addressed pain, portability, and adjustability while trading off weight, speed, and complexity.
Does AI mean the demand on labor goes up?
The page argues that AI may increase, not reduce, labor demand. As tools become more capable, people do more work, raise expectations, and turn saved time back into work.
A Software Architect’s Guide to API-First Strategy
The article argues that API-first design makes APIs the starting point for development, improving governance, security, developer experience, scalability, and AI readiness across complex systems.
How I use AI agents to write code
The author says AI agents are useful when paired with project guidance, tests, plan mode, and repeated review loops, even if they still make common mistakes and feel frustrating.
The fate of “small” open source
The post argues that LLMs make small utility libraries less necessary, which weakens both their reason to exist and their role in teaching developers. Open source still matters, but the author thinks its value is shifting toward larger, more inventive, or niche work.
Let’s learn how modern JavaScript frameworks work by building one
The post explains how post-React frameworks converge on reactivity, cloned templates, and newer web APIs, then builds a small framework step by step to show how those pieces fit together.
