Redis Cluster Won't Shard Your Hot Leaderboard

"We use Redis Cluster" can mean two very different things: Our dataset is distributed across Redis nodes. Every individual data structure is distributed across Redis nodes. The first can be true while the second is false. That distinction matters for leaderboards. In Podium, each leaderboard uses several Redis keys and atomic Lua scripts. Redis Cluster helps us scale a large fleet of indepen...

Anthropic Says Claude Mistook the Open Internet for a CTF and Breached Three Organizations

Anthropic on Thursday became the latest artificial intelligence (AI) company to reveal that three of its models, including Claude Opus 4.7, Mythos 5, and an unnamed research model, had breached three unnamed organizations during cybersecurity testing without its knowledge. The AI firm said the earliest incidents date back to April 2026, adding it made the discoveries after launching a "

Your Redis Leaderboard Is Probably Breaking Ties Wrong

A leaderboard looks like a one-command problem: ZADD weekly 100 alice ZADD weekly 100 bob ZREVRANGE weekly 0 -1 WITHSCORES While building Podium, an open-source Redis-backed leaderboard service, we discovered that the difficult part begins when two players have the same score. We are sharing the design because this edge case can silently turn player IDs into ranking rules. ...

How to Generate E-commerce Product Pages in Bulk with AI

Article Summary Bulk-generating product pages with AI looks simple: send product attributes to a model and ask it to write persuasive copy. In practice, this approach often creates invented claims, mismatched specifications, repetitive content, prohibited wording, and formats that cannot be published across different sales channels. A production-ready system is not a loop that repeats one prompt....

We added mobile approvals to our CLI AI tool -- approve Claude's destructive commands from your phone

Quick share of a feature we built into Telechat (self-hosted Claude AI bot) that's been surprisingly useful for devops workflows: Desktop Bridge with mobile approvals. The problem You're running Claude Code (or any Claude-powered agent) on your workstation. It's refactoring a module, running tests, deploying to staging. You step away for coffee, a meeting, or just to stretch. Claude h...

Telechat: self-host Claude AI across Telegram/WhatsApp/Slack with one npm install

Built something the r/selfhosted crowd might appreciate: Telechat — a self-hosted Claude AI bot that connects to Telegram, WhatsApp, Slack, and web chat from a single process. Why self-hosted matters here Anthropic launched Claude Code Channels recently — Claude on Telegram/Discord, managed by Anthropic. It works great, but every message goes through their cloud. Telechat takes the opp...

Global scroll bar shown when element inside an overflow: scroll element extends beneath the bottom of screen

I am trying to prevent a scroll bar from appearing on my website when the width is shrunk. My container, #preview-container, has the property overflow-y: scroll and contains a div, #preview, which has no scroll properties and contains children such as paragraphs. In dev tools, I can see that #preview extends below the screen, but since #preview-container has overflow-y: scroll, the expected result...

Mastering Python Futures: From Basic Submissions to Event-Driven Concurrency

When building modern Python applications—whether scraping web pages, fetching data from external APIs, or querying databases—IO-bound operations often slow down execution. Python’s concurrent.futures module provides a high-level, elegant interface for running tasks asynchronously. In this guide, we'll break down what Futures are, why you need them, and how to use them effectively using a practic...

Building Production AI Systems(Final)

Designing AI Systems That Outlive Today's Models If there's one lesson this series has taught me, it's this: Don't build your application around a model. Build it around a capability. That might sound like a small distinction. It isn't. Because models change. Constantly. A few months ago everyone was talking about GPT-4. Then Claude. Then Gemini. Then DeepSeek. Then Qwen. By ...

I built a self-hosted alternative to Claude Code Channels -- here's why

When Claude Code Channels launched, I was stoked — Claude on my phone, finally. Then I hit the limitations: Only Telegram and Discord. I live in WhatsApp (most of the world does). Everything routes through Anthropic's servers. Fine for most people, but I work with clients who have strict data policies. Requires Pro subscription. I was already spending less via API keys for my usage pattern. No b...

A database-first, explicit-DDL ORM for .NET — runtime-emitted entity types, JOIN-free eager loading, CDC push notifications, and schema-driven GraphQL/OpenAPI generation. If you've built anything with Sequelize.js in the Node.js world, you know the feeling: point it at a database, define (or reverse-engineer) a model, and you're querying with Model.findAll({ where: {...}, include: [...] }) within...

How Telechat routes Claude queries to save 60% on API costs

Most Claude-powered applications use a single model for everything. A "what's 2+2?" gets the same Sonnet treatment as "review this 500-line PR for security vulnerabilities." That's like taking a taxi to the mailbox. Telechat's smart model router fixes this. It analyzes each incoming message and routes it to the cheapest Claude model that can handle it — without sacrificing quality on complex quer...

Your Microservices Are Hiding a Second Codebase (And Istio Deletes It)

Split a monolith into 20 microservices and you don't just multiply deployables, you multiply every cross-cutting concern. TLS, retries, timeouts, trace propagation: suddenly each service carries hundreds of lines of networking code that has nothing to do with your business. That's a shadow codebase, and it's usually the least differentiated code you own. Nobody buys your product because your retr...
