Created a vector design editor running in the browser. React & Leafer UI. Feedback appreciated!

For a week i was behind leaferjs - wonderfull canvas library. I started building something with the library, but now it's almost a vector editor. It can create shapes, texts, and frames using an endless canvas. Everything is done on the client side, there is no backend at all. What it can currently do: 9 tools (rect, ellipse, line, star, pen, text, image, frame, select) multiple gradient stops, 1...

75 Destinations Ranked by Daily Budget: 2026 Data

I started planning a beach trip this summer. Pulled up the destination data on my site to compare options. Maui was sitting at $170 a day. Cancun was $45. Cartagena was $40. The number that caught me was not the cheapest, it was the gap. A week in Maui at the budget tier runs as much as four weeks in Cartagena. Same beach archetype, four times the spend. That sent me down the ranking. 75 destinat...

From Monolith to Microservices: Why Your App Needs to Break Apart

From Monolith to Microservices: Why Your App Needs to Break Apart The software world is split: monolith believers and microservices advocates. If you're building cloud-native applications today, it's time to understand why the industry is shifting, and more importantly, how containerization makes the transition possible.

I Built an AI That Has to Lie to the Internet to Do Its Job

At PCI Oasis Inc , I was handed a task that sounded simple on paper: "Help build a crawler that navigates e-commerce websites from the homepage to the checkout page." Easy enough, right? Open a browser, click some buttons, reach checkout. Done. Except the internet doesn't want you to do that. The Problem Nobody Talks About Every major e-commerce platform, your favourite fashion bra...

Dr. Strangelove or How I Learned to Stop Worrying and Love Testing

When I was still programming at university, my “testing” looked roughly like this: std::cout << "Value: " << value << std::endl; along with some classic debugging: setting breakpoints, inspecting variables, stepping through the code. Looking back, this was clearly not an effective approach. I don’t even want to know how many bugs went unnoticed back then. Over several pr...

HTML-in-Canvas Feels Fake Until You Try to Build With It

HTML-in-Canvas Feels Fake Until You Try to Build With It

HTML-in-Canvas feels fake the first time it works. Real DOM. Real CSS. Real layout. Inside canvas. You write a tiny canvas.onpaint, call drawElementImage(), and the browser just… does it. Your styled HTML is suddenly part of a canvas frame. Beautiful. Then you try to build an actual app. Now you have multiple surfaces, resize logic, export timing, React unmounts, cleanup, invalidation, and t...

Your Runbook Is Written. Nobody Runs It.

The runbook was pinned. Owners in the footer. Audit passed. Then a routine change hits, the on-call opens the page, step four does not match what production actually is, and the sane move is to close the tab and do what the last hero did ... because nobody has treated "bring the doc back to truth" as release-critical work. That is not a missing wiki problem. That is a trust problem wearing a Confl...

In light of the ongoing npm supply chain compromises, I built safe-install: https://www.npmjs.com/package/@gkiely/safe-install It brings a couple of protections I wanted from npm but are not built in. Similar to Bun’s trusted dependencies, it lets you disable install scripts and define a list of dependencies that are allowed to run build/install scripts: https://bun.com/docs/guides/install/trusted...

I Built ClockAura: A Free Online Timer Platform with React + Vite (My Solo Dev Journey)

Live at clockaura.com Why I Built ClockAura As a solo developer, I noticed something annoying: every "free online timer" site was either: 🚫 Ugly and outdated (looks like 2005) 🚫 Full o...

Open source GPU accelerated Image viewer for Windows

Hi all! It's my first post in reddit; some time ago I made an open source image viewer for windows, because the one I liked (picassa from google) has been discontinued long ago and doesn't support some file types, high resolution displays, high refresh rate, animated gifs, etc. Here it is: https://github.com/LuisJalabert/Picasso-Pictures https://preview.redd.it/imnsjtkjjy0h1.png?width=2388&fo...

Two days lost to PGRST116: when Supabase RLS hides a successful write

TL;DR. Our Supabase upsert wrote the row. The chained .select().single() returned PGRST116. The wrapper read that as a failed write. The frontend retried. The retry was wrong. Two days to find why. We've been running an LMS on Supabase for the past several months — auth, RLS on every table, FastAPI talking to Postgres. The bug below cost us two days last quarter, and the fix changed how we read...

We built an enterprise integration stack for .NET from scratch: EAV + DSL + runtime

Three open-source libraries. One coherent stack. All Apache 2.0. This is the story of what we built, why, and how the three pieces fit together in a way that surprised even us. The problem Enterprise .NET integration in 2026 still looks like this: EF Core for data — plus a migration file every time a field changes MassTransit or NServiceBus for messaging — great if you only need m...
