Hola comunidad 👋 Soy Frank, desarrollador desde La Habana, Cuba. Quiero compartir con ustedes Boniatillo, una red social completa que construí desde cero para resolver un problema real: las plataformas extranjeras no funcionan bien en Cuba. El problema En Cuba tenemos varios desafíos
The flag is XOR-encrypted with a short repeating key. Since we know every picoCTF flag starts with picoCTF{, we XOR that known text ("crib") with the beginning of the ciphertext to recover the first bytes of the key, then complete the key by finding the repeating pattern. Platform: picoGym Categ
After a lot of coding, learning, changing ideas, and rebuilding things, I finally launched my personal portfolio. 🌐 https://faridteymouri.com I didn't want it to be just a simple "about me" page. I wanted a place where I can share: Projects I build Things I learn along the way Technical experie
Hello, I'm Rijul, and I'm building LiveReview — a blast-radius aware AI code review built for your business-critical systems. Star us to help devs discover the project, give it a try, and share your feedback to help improve the product. If you are familiar with RAGs, you know its usual flow.
Machine learning workflows often suffer from code duplication, data leakage, and hyperparameter tuning complexities. Scikit-Learn's Pipeline and ColumnTransformer modules simplify this by combining feature preprocessing and model estimation into an integrated, reproducible object. This guide demons
I've been working on Pinball King Karma, a full pinball game that runs directly inside Reddit using Devvit Web. Play it here: https://www.reddit.com/r/pinballkarma_dev/comments/1s2twov/pinball_king_karma_play_now/ The current stack includes: HTML5 Canvas Box2D / Planck.js for physics CreateJS for r
Flutter enables you to deploy a single application across phones, tablets, desktops, and the web. The challenge lies in designing an interface that feels purposeful on each platform. A phone layout stretched across a desktop window wastes space. A dense desktop dashboard squeezed onto a phone becom
Hello, I'm Maneshwar, and I'm building LiveReview — a blast-radius aware AI code review built for your business-critical systems. Star us to help devs discover the project, give it a try, and share your feedback to help improve the product. Here's a fun fact that nobody puts on the slide at the AI
Your CPU is fine. Your memory is fine. Your database is fine. So why did the application suddenly stop calling another service? There is a class of production failure that is particularly dangerous because your application metrics can look completely healthy while the application is already running
A verifier went red and named a neighbouring tool as the cause. Three of eight rows could not be matched, and the reason code said the rows had the wrong shape. Two things were wrong with that. The neighbouring tool was innocent, and the reason code was lying. FAIL rows=3/8 unmatched reason=

Hey WebDev! I work with Redis on my projects all the time, and I recently had to dig deeper - deep enough to actually dive into the project's source code This gave me the idea to create an interactive 3D map showing how Redis works and visualizing its internal structure (I’d seen similar projects fo
Blizzard originally tried to bring the StarCraft universe to the world of 3D shooters way back in 2002 with StarCraft: Ghost. It sat in development hell for years until Blizzard president Mike Morhaime confirmed that it had been canceled in 2014. Now Blizzard is giving it another go with the simply
What Git worktrees, parallel coding agents, and a cache pointing at the wrong directory taught us about the assumptions hiding inside node_modules. I’m a developer at bol, where we have been building and running our internal developer platform on Backstage for more than five years. After that mu
Every frontend developer has experienced this sequence: You start building an interactive web application. The backend is not yet ready, so you connect to a popular free mock API like JSONPlaceholder or a local static db.json file. You fetch data with a GET request. The cards render nicely on scre
TL;DR: My entire mobile stack costs $0 a month. Expo builds the app. Supabase holds data and auth. Render runs background jobs. Vercel hosts the landing page. Free tiers cover all of it. The table below shows every piece, its limit, and the catch. Steal this setup. My infrastructure bill is zero do
For anyone passionate about digital sovereignty and homelabbing, setting up a private home server on a Single Board Computer (like a Raspberry Pi 5, Orange Pi) or a Proxmox home lab is one of the most rewarding engineering projects. However, anyone who has managed a growing homelab knows the frict
TL;DR: GitHub login in my Expo app broke three separate times. A deep link that went nowhere. A PKCE flow I wired backwards. A redirect URL with a typo. Each fix is copy-pasteable below. Total auth code is under a hundred lines. Steal it. Auth is the worst part of every app. Nobody downloads your a
TL;DR: I was the bottleneck on every pull request. Reviews waited days for me. So I built a PR inbox for my phone. AI summarizes each diff. I swipe right to approve. Built with Expo and Supabase. Costs $0. This is post one of the build-in-public series. I am the problem. Let me say that first. Eve
I added three new checks to a build. Nothing about the code under test changed. Ten tests that had nothing to do with any of them went red, and a separate, unrelated block of work was refused outright. Both of those were correct. FAIL_ORACLE reason=row_without_its_oracle_or_fault_cells
