Python Math Stack: Decimal, Statistics & IEEE 754 Limits (2026)

Day 19: The Mathematics of Python (Part 1) — Hardware Limits & Absolute Precision 35 min read Series: Logic & Legacy Day 19 / 30 Level: Senior Architecture ⏳ Context: We have mastered the flow of data through Operating Systems and Databases. But data is useless if the mathematical transformations applied to it are fundamentally flawed. "I lost $10,000 because 0.1 + 0.2 != 0.3..." Code is just syntax. Mathematics is the universal law governing that syntax. Junior developers assume that if they ty

S3 Bucket Names Just Got Simpler — Here's What Actually Changed

If you've worked with S3 for a while, you know the drill. You go to create a bucket, pick a name that makes sense for your project, and AWS tells you it's already taken. Not by you. Not by anyone in your org. Just — taken. Because S3 bucket names have always been globally unique across every account, every region, worldwide. So over time, most of us started appending things manually. Account IDs. Region names. Random strings. Whatever it took to avoid collisions. It worked, but everyone solved i

Building an Interactive N-Queens Visualizer with React + TypeScript

Building an Interactive N-Queens Visualizer with React + TypeScript I rebuilt this write-up after a full master-branch audit and focused it on what the code actually ships today: a single-page interactive algorithm visualizer with real-time constraint feedback, simulation playback, and responsive controls.

Stop re-writing this: How to build a reusable Password Input in React Native

If you are building a React Native app, you are going to need a Login screen, a Registration screen, and probably a "Change Password" screen. The biggest mistake I see developers make is re-writing the same useState logic to toggle the secureTextEntry (the eye icon) on every single one of these screens. It makes your code messy and violates the DRY (Don't Repeat Yourself) principle. Instead, we should build a single, beautiful component that handles its own internal state, and just reuse it ever

How I Built My Portfolio Website with React + Vite: Themes, Particles, GitHub Visualizations, and a Dev.to-Powered Posts Page

How I Built My Portfolio Website with React + Vite: Themes, Particles, GitHub Visualizations, and a Dev.to-Powered Posts Page I recently rebuilt my personal portfolio to reflect how I like to build products: clear architecture, expressive UI, strong performance defaults, and data-backed sections that stay fresh.

Is Railway Reliable for SaaS Apps in 2026?

You can host a SaaS app on Railway. The harder question is whether you should. Based on Railway’s current documentation and a persistent pattern of production complaints on its own community forum, the answer is usually no. For a real SaaS application with paying customers, background jobs, persistent tenant data, custom domains, billing flows, and on-call expectations, Railway remains a risky default. The issue is not whether it can run your app. The issue is whether it absorbs enough operation

BuildWithAI: Architecting a Serverless DR Toolkit on AWS

Overview I'd been getting more involved in disaster recovery planning lately and kept running into the same gap — a lot of teams on AWS have backups, but not a real Disaster Recovery (DR) plan. No documented runbooks, no tested failover procedures, no RTO/RPO targets tied to business impact. So that became the motivation for this side project: six AI-powered tools that automate the tedious parts of DR planning, built entirely on AWS. In part one of this three-part series, we will walk through th

Why AI Systems Pass Audits and Still Fail in Production

Domain: Behavioral AI Governance Summary Many AI systems pass audits. They meet performance thresholds. They satisfy compliance requirements. And they still fail in production. Problem Enterprise governance is designed to validate systems before deployment. audits benchmarks controlled evaluations These assume that if a system passes, it is safe to operate. But AI systems do not operate in static conditions. They operate continuously. What Actually Happens After deployment, systems: adapt to new

scan-for-secrets 0.2

Release: scan-for-secrets 0.2 CLI tool now streams results as they are found rather than waiting until the end, which is better for large directories. -d/--directory option can now be used multiple times to scan multiple directories. New -f/--file option for specifying one or more individual files to scan. New scan_directory_iter() , scan_file() and scan_file_iter() Python API functions. New -v/--verbose option which shows each directory that is being scanned.

scan-for-secrets 0.1.1

Release: scan-for-secrets 0.1.1 Added documentation of the escaping schemes that are also scanned. Removed unnecessary repr escaping scheme, which was already covered by json .

scan-for-secrets 0.1

Release: scan-for-secrets 0.1 I like publishing transcripts of local Claude Code sessions using my claude-code-transcripts tool but I'm often paranoid that one of my API keys or similar secrets might inadvertently be revealed in the detailed log files. I built this new Python scanning tool to help reassure me. You can feed it secrets and have it scan for them in a specified directory: uvx scan-for-secrets $OPENAI_API_KEY -d logs-to-publish/ If you leave off the -d it defaults to the current dire

From Copilots to Coordination: Why Agentic AI Changes System Design

Most technical discussions around AI still focus on one question: how much faster can it make existing work? That is useful, but incomplete. I ( Rizwanul islam Afraim) recently published a paper on SSRN arguing that agentic AI should not be understood only as a productivity tool. It should be understood as a coordination-layer technology.

Beyond Autocomplete: How AI Agents Are Transforming Business Operations in 2026

Beyond Autocomplete: How AI Agents Are Transforming Business Operations in 2026 The conversation around AI in software development has shifted dramatically. In 2024, we debated whether AI tools were useful. In 2025, we measured productivity gains. In 2026, we're asking a different question: How do we build systems where AI doesn't just assist—it executes? This isn't about faster code completion or smarter autocomplete. It's about AI agents that understand context, take autonomous action, and ope

I Tested Every 'Memory' Solution for AI Coding Assistants - Here's What Actually Works

Every AI coding session starts from scratch. You open Claude Code or Codex, and it has no idea that your team uses JWT with 15-minute expiry, that you migrated from REST to GraphQL last month, or that the payments service is the one thing you never touch on Fridays. You re-explain the same architecture decisions, the same conventions, the same constraints. Every single time. This is not a minor annoyance. It is compounding time loss. The first 5-10 minutes of every session is wasted on context t

135,000 OpenClaw Users Just Got a 50x Price Hike. Anthropic Says It's 'Unsustainable.'

Originally published at news.skila.ai A single OpenClaw session can burn through $1,000 to $5,000 in compute. Anthropic was eating that cost on a $200/month Max plan. As of April 4, 2026 at 12pm PT, that arrangement is dead. More than 135,000 OpenClaw instances were running when Anthropic flipped the switch. Claude Pro ($20/month) and Max ($200/month) subscribers can no longer route their flat-rate plans through OpenClaw or any third-party agentic tool. The affected users now face cost increases

research-llm-apis 2026-04-04

Release: research-llm-apis 2026-04-04 I'm working on a major change to my LLM Python library and CLI tool. LLM provides an abstraction layer over hundreds of different LLMs from dozens of different vendors thanks to its plugin system, and some of those vendors have grown new features over the past year which LLM's abstraction layer can't handle, such as server-side tool execution. To help design that new abstraction layer I had Claude Code read through the Python client libraries for Anthropic,
