I'm fed up. I'm developing projects (SaaS, mobile apps) and looking for people who are interested in what I'm doing. But I'm not getting any responses. Even though it's free to be a tester, I'm still getting nothing. So I don't know what to do. I don't know if I should stop working on these kinds of projects. I'm just fed up.

I'm a huge fan of augmented reality games like Ingress and Pokémon Go. I've always dreamed of building my own version, but until about a year ago, it simply wasn't possible. After several months of work, I've finally finished my own Pokémon Go version. The biggest challenge was placing 247 million points all around the world while avoiding dangerous or inaccessible areas such as roads, lakes, houses, and private property. To solve this, I built my own algorithm using OpenStreetMap data. Afte...

A month ago, I decided to put all my energy into SpacePlanner and try to turn it into the #1 free, no-sign-up space planning app that actually gives people real value. Since then, it has grown to more than 200 daily users and over 1,500 plans created, and few hundred guest users! The last few days have been intense, mostly fixing bugs, improving stability, and trying to make the editor less frustrating. I also think I may have overengineered some features that people do not really need. I ...

Why? For years we've had open formats for documents (PDF), images (PNG) and graphics (SVG). But user interfaces are still mostly locked inside design tools. And that was fine when humans were creating and consuming UIs. Now AI is also creating and consuming them. Today AI usually works with screenshots, editor-specific JSON, or tool-specific APIs. They work, but they weren't really designed for AI or for moving designs between different tools. So I started building . gui . The idea is si...

I'm a bit torn on how to approach this because a customer is a customer and you all know how difficult it is to get them, but I don't want my saas to get a weird or bad reputation. My startup is an authentication and paywall software that allows creators to lock their content until someone signs up or purchases. It's usually used by digital goods stores or online courses. However recently there have been a lot of people using it for purposes not entirely foreseen when I created it. I am caut...

You've built and consumed APIs. You know what a GET request is, what a JSON response looks like, and how to add an Authorization header. You've used REST, maybe tried GraphQL, and perhaps heard of gRP

Imagine your team deployed Prompt A globally two weeks ago. Tight deadlines and high confidence meant the rollout hit 100 percent of users without any A/B testing, shadow traffic, or holdout groups. W

What happens when an engineer gets fed up with corporate lawyers breathing down their neck? Sometimes, you get an inside joke that quietly ships to millions of machines and survives for over three dec

Anthropic is expanding its official certification ecosystem, and advanced practitioners now have a dedicated path to validate their expertise with the release of the Claude Certified Architect – Found

Modern software engineering is evolving into an ecosystem where AI actively participates in planning, coding, and deployment. To help bridge the gap between initial concepts and fully shipped products

Every application, at some point, needs to talk to another system. A mobile app talks to a backend. A backend service talks to a payment gateway. An authentication service talks to a user service. A d

Most tutorials on programmatic advertising stop at the web banner. That's a shame, because the idea gets far more interesting once you follow it off the screen and into the physical world. If you've n

In this article, you'll build an accurate mental model of what a Container Network Interface (CNI) actually does. Not by reading YAML, but by doing every single step it does by hand with raw Linux ker

When an AI assistant answers a question, it lifts sentences from a handful of pages and cites them. Whether your page is liftable is not a mystery or a vibe. It's a set of mechanical properties of you

You asked the AI to write a function. It gave you something that looks right. It even runs. But is it actually good? Most engineers stop there. They see green and move on. That habit will quietly caus

Most prompt engineering tutorials follow the same shape. Install the SDK, paste your API key, call generateContent, and print the response. The model says something plausible and the tutorial ends. Th

A date and time picker is one of those components that looks small in a design file and turns into a real time sink once you start building it. You need a calendar, a time selector, a state that keeps

Most segmentation tutorials begin by choosing a model, feeding images into it, and tuning hyperparameters until the metric improves. But this skips the step that often matters most: understanding the

In this tutorial, I'll show you how to trace and monitor a local AI agent with LangSmith. We'll build a small local AI agent and then enable LangSmith tracing for it so that we can inspect model calls

When you maintain a document for someone else, such as a résumé, a one-page portfolio, or a printable menu, the bottleneck is rarely the layout. It's the edit loop. Every small change ("move this bull

Retrieval-Augmented Generation, commonly known as RAG, has become one of the most widely used approaches for building applications with large language models. Instead of asking an LLM to answer entire

When people think of Geoffrey Hinton, they usually think of backpropagation, Boltzmann Machines, Deep Belief Networks, or the deep learning revolution that transformed artificial intelligence. But few

In this tutorial, I’ll show you how to serve a multi-user local AI agent as a REST API using FastAPI, then add a lightweight Streamlit UI on top. Instead of interacting with the agent through a termin

It's mid 2026, and the best frontier models out there still hallucinate. I want you to gain two things from reading this article: understanding that AI hallucinations are still real and possibly harmf

Health data is having a moment. Of all the metrics receiving the most developer interest at present, there’s nothing like heart rate variability (HRV). It’s a feature found on every major SDK for wear

A colleague asked me to help debug what looked like a permissions issue in their SaaS project management tool. Users were seeing resources they hadn't created. I pulled up the query logs expecting som

PDF documents are commonly used for agreements, forms, approvals, invoices, reports, applications, and other documents that may need a signature or additional text before they are shared. A traditiona

In this article, you'll learn how to optimize SQL Server performance using T-SQL query tuning, indexing strategies, execution plans, and real-world optimization techniques for enterprise applications.

Not every AI feature needs a cloud model, with its per-token bills, network round-trips, and private data leaving your machine. If you're on a modern Mac, a capable language model is already on your d

Last year a client called me about exactly this. Someone ran git log -p on a hunch and found a .env committed two years earlier, never caught. Database password, Stripe secret, JWT signing key — all s
