There are meticulous, tenacious people who have learned to squeeze genuinely serious answers out of smart chats. They're in no hurry to share their method — for each of them, it's a personal competitive advantage, a source of professional authority. And there's a huge mass of users who mostly mess around with AI doing nonsense: asking it to do their work for them, trying to needle it, asking primitive questions without supplying important context — and getting predictable nonsense back, because ...

AI doesn't improve your thinking, it just reveals its quality. Clear thinkers use it to accelerate their work, while unfocused thinkers get polished nonsense. The real danger is letting AI take over your judgment, which is the one thing it can't automate. To stay sharp, use AI as a sparring partner to challenge your ideas, not as a replacement for having them.

Your local LLM runs fine until the context fills up past a certain point - then generation speed can drop by ~50%. The cause is the KV cache spilling out of VRAM into slower shared memory. On Windows it happens silently, with no out-of-memory error to warn you.

Over the past few months I've been heavily involved in the decompilation community. I've been hands-on decompiling a beloved game from my childhood (Star Fox Adventures). I started this journey with zero prior decomp experience—and to make things worse I had never really touched C nor assembly either. Learning how to decompile was challenging. It's difficult to find any good learning resources for it and any open-source projects for this are inactive and/or contain little actual learning materia...

Teenage Engineering has already issued multiple substantial updates for its surprisingly capable $329 EP-133 KO II sampler. Its latest is one of the biggest yet. OS 2.5 adds audio over USB, selectable sample rates for lo-fi fun, sample reverse, an arpeggiator, equal-length autochopping, and it extends the maximum length of a sample from 20 seconds […]

Not everyone is buying Elon Musk’s vision for orbital data centers.

Instagram users could soon see more ways to tune their content.

I indexed the WordPress.org plugin directory and measured how well it is maintained. The headline: of the 57,383 plugins in the index, 45.6 percent have not shipped an update in 24 or more months. Data is as of June 2026. Here is the full staleness picture, measured against plugins that report an update date: 65 percent: no update in 6+ months 56 percent: no update in 12+ months 45.6 percent: no update in 24+ months 41.2 percent: no update in 36+ months "Not updated in two yea...

The Problem with Learning Kubernetes Kubernetes documentation is thorough. It's also overwhelming. Terms like "control plane," "kubelet," "etcd," and "pod" get thrown around without a unifying mental model. Here's the analogy that made it click for me: Kubernetes is an airport control tower. The Control Plane = Air Traffic Control The control plane doesn't run your containers (fly the planes). It orchestrates where they run and ensures the system stays healthy. ...

No necesitas un SaaS de video para poner a dos personas en una llamada. Con un plano de medios administrado (aquí AWS Chime SDK, pero la forma se generaliza), el lado del servidor de una videollamada 1:1 es una reunión, dos tokens de ingreso, y un interruptor de apagado. Este post construye exactamente eso, una llamada host ↔ guest con grabación, sobre FastAPI + SQLAlchemy + un cliente de React, y mantiene la cuenta predecible. elchesco / ...

Memilih antara platform AI knowledge base siap pakai ( off-the-shelf ) dan sistem yang dibangun dari awal bukan soal mana yang lebih canggih—ini soal kontrol, kepemilikan data, dan apakah sistem itu masih bekerja dengan baik dua tahun dari sekarang. Dua pendekatan ini memiliki logika masing-masing, dan kesalahan paling umum adalah memilih salah satunya karena tekanan waktu, bukan karena analisis kebutuhan. Analisis Kebutuhan Bisnis: Kapan Memilih Solusi Instan ( Off-the-shelf )? ...

From OpenClaw to Norax OpenClaw was my first AI agent. It worked, but it was built on borrowed infrastructure. Norax is the rebuild — ground-up, every line mine. What OpenClaw Taught Me Own your stack — Don't depend on others' runtimes Memory is everything — OpenClaw forgot everything after 50 messages. Norax has 11,000+ canonical memories with entity graph retrieval Tools need guardrails — Loop detection, write verification, parallel execution Cost optimiz...

This article is part of my submission to the H0: Hack the Zero Stack hackathon, in the Monetizable B2B App track. Most "AI apps" treat the model as a stateless add-on: a chat UI tacked onto a CRUD app, calls billed to an API key the developer hopes nobody finds. The database stores the chat history; everything interesting happens outside it. For a B2B SaaS where the AI writes financial records, drafts livestock medical notes, and creates operational tasks on behalf of paying customers, ...

The release of React 19 brings exciting new features and patterns, but it also creates immediate friction for development teams working with existing ESLint configurations. Many developers encounter warnings about deprecated or unstable APIs that were once acceptable, particularly around default props patterns that have been standard practice in React codebases for years. These warnings force teams to make difficult decisions: update existing code, ignore the warnings, or find a middle ground th...

Most teams building a web + mobile product end up with two auth integrations that slowly drift apart. You don't need that. Here's how to run a single Supabase auth layer across a Next.js web app and an Expo mobile app in a monorepo — including the gotchas nobody warns you about. 1. Keep the Supabase client framework-agnostic Depend only on @supabase/supabase-js . Expose a factory that takes the storage adapter as an argument: export function createSupabaseClient({ url, ano...

A few weeks back I shipped Warden, a governance layer that sits in front of an MCP server and enforces who can read what. Role-based, field-level. The demo had a support role that could list customer accounts but never see their billing tier . The tier field is stripped from everything support gets back. I was poking at it the way you poke at your own work when you don't quite trust it.. I tried this: query_resource ( " accounts " , { " tier " : " Enterprise " })...

A developer-focused guide to the APIs quietly powering Africa's rapidly growing digital payment ecosystem. Introduction Every time you pay with your phone, fund a digital wallet, or receive an instant payment confirmation, dozens of systems communicate behind the scenes in milliseconds. At the center of that communication is one technology: the Application Programming Interface (API). Across Africa, fintech APIs have become the invisible infrastructure connecting banks, mo...

"Use a strong model to orchestrate, a cheap model to execute." This is now the default cost-aware recipe for agentic coding. I believed it and ran the experiment. Opus 4.7 as the orchestrator, locally-hosted Qwen 3.5-9B (zero token cost) as the executor. This should beat running Opus alone on cost. Has to. It did the opposite. The supposedly "free" configuration (Opus + Qwen) came out as the most expensive cloud arm on all three of the code-repair tasks I ran. Higher than Opus solo. H...
