Escape the cloud

A local-first platform where users own their data cryptographically — built on encrypted SQLite, CRDTs, and libp2p. Here is the simplest thing you can do with the platform: const platform = await createPlatform() const rows = await platform.exec( 'SELECT * FROM notes WHERE scope_id = ?', ['user:alice'] ) That looks like any other database query. The difference is where it runs. The...

Why Is Redis INCR a Bad Fit for a Public URL Shortener?

Why Is Redis INCR a Bad Fit for a Public URL Shortener?

LeetDezine Redis INCR is one of those solutions that looks perfect the first time you see it. Atomic counter increments. Every call returns a unique integer. Base62-encode it and you have a short code — zero collision checks, zero retries, no background service. It's cleaner than anything else on the board. So why does every serious URL shortener reject it? The answer has nothing to do with co...

Finding a Practical Analytics Format for Structured JSON Logs

Structured JSON logs are easy to produce and hard to analyze at scale. They carry useful context, but that context is nested, optional, inconsistent, and often wider than expected. Before the data can be queried comfortably, it usually has to become a table. The question is not only "can we flatten it?" The more useful question is: After flattening, what should the output be? CSV is simple an...

Working with JSON in Python Explained Simply

JSON (JavaScript Object Notation) is a common format for storing and exchanging data. Python's json module makes it easy to work with JSON. What is JSON? JSON looks similar to Python dictionaries and lists. Example JSON data: { "name": "Alex", "age": 25, "hobbies": ["reading", "coding", "hiking"], "is_student": false } Importing the json module Alwa...

Proof of Usefulness: How Hackathons Scale Startups

Hackathons are evolving from flashy demo contests into "Proof of Usefulness" engines that prioritize rapid prototyping, real-world utility, and immediate distribution. By focusing on usage metrics and technical depth rather than just pitch decks, founders can secure immediate liquidity (part of a $150k+ prize pool), gain permanent SEO visibility on HackerNoon, and bridge the gap from MVP to market...

Why I Stopped Using LangGraph

Most small LLM applications don't need a state graph framework. I know this because I used LangGraph in 8 out of 10 AI projects I built—and eventually replaced it in most of them. I want to be clear upfront: LangGraph is well-built software. The team behind it is sharp, the abstractions are thoughtful, and for genuinely complex multi-agent workflows, it earns its place. This isn't a takedown. It'...

Why I built a Rust deep learning framework (and what I got wrong twice first)

The Python script that made me give up. It had more boilerplate for freezing and re-composing submodules than it did for the actual model. I'd already pivoted three times. The next pivot was going to cost another rewrite. That's the day I decided to build this in Rust. I should say upfront: before this, I had never trained a deep learning model. The path to here was unusual. A theoretical physics...

If your refresh token gets stolen, rotation alone won't save you — here's what does

Standard advice for refresh tokens is pretty straightforward: rotate on every use store them hashed keep expiry short Done, right? Not quite. Rotation alone does nothing against token theft. If malware or XSS lifts a refresh token from a legit client, the attacker and the client effectively race to rotate it. whoever loses the race gets a "token revoked" error whoever wins keeps the session ...

Claude's Law

I came across the post on Hacker News titled Laws of Software Engineering. Within, Dr. Milan Milanović outlined 56 laws of software engineering practices, many of which have originated from old men known as "greybeards." These laws are familiar to software engineers; they are regularly discussed and battle-tested. But now there is this weird gap in coding practices, lacking laws: managing agents ...

Using a Custom Template for LearnDash Courses

One of those niche little things but I don’t see a lot of folks sharing WordPress snippets these days. You have a LearnDash-powered course. It has pretty decent templates out of the box. You can certain override them in your theme directory, but the documentation s rather light. There’s a plugin you can use, but […]

Debugging Voice Agents: How to Know if Your STT, LLM, or TTS Is the Problem

Something went wrong. The agent said something bizarre, or paused for three seconds, or completely misunderstood the user. The real question is: which layer broke? The answer isn't obvious, and guessing is expensive. Here is the thing about debugging a voice agent that nobody warns you about upfront: failures are almost never where you think they are. A voice agent that gives a wrong answer is...

What if AI is not accelerating us but keeping us exactly where we are

I have been thinking about this for three months now. Not constantly but enough that it started affecting how I work. How I open my editor. How I reach for AI or decide not to. The question is simple but the answer scares me. Is artificial intelligence helping us build the future or is it just making us extremely efficient at staying in the present? Let me explain with something that happened ...

Beyond the Dashboard: The Trick to Winning Over Your Clients with AI

Let's be honest: if you have a project or business idea that already handles clients and a database, you're sitting on a goldmine. Information is everything nowadays.

Almost all developers do the same thing: we collect the data, build a pretty dashboard with a couple of charts, and cal...

I Built a Toast Library Where a Robot Delivers Your Notifications 🤖

Every React app needs toast notifications. So there are roughly a thousand toast libraries on npm. I built another one. But this one has a robot. Why though? I was building a side project and dropped in react-toastify. Functional. Totally forgettable. Then tried sonner — cleaner, but still just a rectangle sliding in from the corner. I wanted something that actually made users p...

The MCP Discovery Problem: Why 7,500+ Servers Is Both a Victory and a Warning

The ecosystem is growing. But finding the right server is getting harder, not easier. There is a number that gets thrown around a lot in the MCP ecosystem right now: 20000+. That is roughly how many MCP servers exist as of April 2026. It is an impressive number. A year ago, there were a few dozen. The growth curve looks exactly like npm circa 2012–2015 — exponential, messy, and full of potent...
