Talon: a self-hosted harness for long-lived AI agents
Most agent demos are one-shot loops. You open a terminal, give the model a task, watch it call tools, and then the process dies. That is fine for coding sessions. It is a weak shape for an assistant that is meant to live in your actual workflow. Talon is built around the other shape: a persistent agent process with frontends, memory, tools, background jobs, and swappable model backends. What it runs on Talon can expose the same agent core through: Telegram Discord Microsoft Teams terminal chat a desktop/mobile companion bridge That means the agent is not tied to one UI. The chat app is just a mouth. The core state, tools, memory, goals, and model backend live behind it. Backends are swappable The same harness can run through: Claude Agent SDK OpenAI Agents Codex Kilo OpenCode Each backend implements the same capability interface, so the rest of the system does not need to care which model runtime is active. It has real operating machinery The important parts are not flashy. They are the things that let an agent keep working after the first message: MCP plugins for tools cron jobs for scheduled actions triggers for condition-based wakeups persistent goals for multi-session work long-term memory heartbeat mode for background progress dream mode for consolidation per-chat model and effort settings This is the difference between "chat with a model" and "run an assistant". Install npm install -g talon-agent talon setup talon start Repo: https://github.com/dylanneve1/talon If this is the kind of agent infrastructure you want more of, a GitHub star helps the project get found.

How Secure is Your Password? Calculating Shannon Entropy in the Browser
We've all seen password strength meters on sign-up forms. Most of them rely on simplistic, static rules: "Must contain at least 8 characters, one number, and one special character." But from a mathematical standpoint, these rules are a poor proxy for actual password security. A password like Tr0ub4dor&3 conforms to these rules but is far easier to compromise than a randomly generated four-word passphrase like correct-horse-battery-staple . To truly measure password security, we have to look at information theory and compute its Shannon Entropy . Here is how password entropy works, the math behind it, and how you can calculate it directly in the browser with 100% client-side privacy. What is Password Entropy? In cryptography, entropy is a measure of the unpredictability or randomness of a password. It is expressed in bits . An entropy of $N$ bits means there are $2^N$ possible combinations that an attacker would have to guess in a worst-case brute-force search. < 28 bits: Very weak (easily guessed in milliseconds). 28 to 35 bits: Weak (cracked in minutes or hours). 36 to 59 bits: Reasonable protection (days to months). 60 to 127 bits: Very strong (takes years to decades to crack). 128+ bits: Extremely secure (mathematically unfeasible to crack). The Mathematical Formula To calculate the entropy ($E$) of a password, we use the following equation: $$E = L \times \log_2(R)$$ Where: $L$ is the length of the password (number of characters). $R$ is the size of the pool of unique characters from which the password is drawn. $\log_2(R)$ is the binary logarithm of the pool size, representing the amount of information carried by each character. Determining Pool Size ($R$) To find $R$, we analyze which character sets are present in the password string: Lowercase letters ( a-z ): 26 characters Uppercase letters ( A-Z ): 26 characters Numbers ( 0-9 ): 10 characters Common special characters/punctuation: 33 characters (e.g., !@#$%^&*()-_=+[]{}|;:',.<>/? etc.) If a password uses ch

The API-First SaaS Manifesto: How to Architect a Production-Grade Application in 2026 Without Building Microservices
Every junior developer or solo software engineer falls into the exact same engineering trap: They conflate writing code with building a business. They spend their initial excitement phase setting up intricate user database authentication schemas, writing custom cron jobs for automated subscription reminders, or building heavy background pipelines just to resize a user’s uploaded logo image. By the time their local environment is "infrastructure perfect," weeks have passed. The momentum is gone, burnout sets in, and the repository is abandoned before ever tasting real production traffic. In 2026, computing power has completely shifted to specialized edge layers. Infrastructure has become commoditized. If you are wasting creative bandwidth trying to compete on backend pipelines instead of focusing entirely on your unique value proposition, you are systematically killing your startup. Here is the architectural matrix to decouple your operational infrastructure and shift to a lean, hyper-scalable API-first codebase. Part 1: The Production Infrastructure Decoupling Layer The golden rule of modern systems design is clear: Your application should only maintain two core pillars internally—your proprietary business logic and your core user state database. Everything else—from security to user tracking—is a solved problem that should be offloaded to third-party micro-services. Let’s look at the financial and time trade-offs of building versus outsourcing across critical technical vectors: Microservice Vector The Native Way (High Friction) The 2026 API Standard Launch Velocity Impact Merchant of Record Raw Stripe API + Custom Tax Calculators Lemon Squeezy / Paddle Saves 5 days of legal & accounting setup Feature Rollouts Custom Postgres feature-flag logic loops GrowthBook / LaunchDarkly Zero deployment overhead for major pivots Customer Feedback Manual tables + Admin CRUD boards Featurebase API Instant roadmaps directly inside frontend Media Compression AWS S3 triggers + Edge

Show HN: Abralo – Free, easy way to run several Claude Code agents in one window
Hi guys, I've been using Claude Code for almost everything lately. Have given one an email account so it can research business leads, draft emails, fact-check them and clear them with me before sending (works really well by the way). I also tend to have a few Claude Code agents running at any one time for coding. I used to create a split terminal to manage them from there, but found working in the terminal all day pretty depressing and, more importantly, found it hard to follow Claude Code's pro

Gaming laptops are too expensive right now, but this one’s a good value
It’s not a great time to shop for a gaming laptop. The unprecedented rise in cost for RAM (and storage to a slightly lesser extent) has made laptops with low-to-midrange specs cost much more than they should. Recent deals on gaming laptops worth your attention have been uninspiring, but one recently caught my eye: MSI’s […]
