The winter in Hangzhou is miserably damp. At 1:47 AM, I was jolted awake by an alert SMS — “User profile page returning mixed values, user A is seeing user B’s orders.” My gut told me it was cache corruption again. After digging around for a while, I found that the invalidation logic between the local lru_cache and Redis had missed a single delete in one branch. I had to manually run dozens of tes
You have probably seen a file named “go.sum” in almost every Go project you have worked on. You may have even seen it change every time you run “go mod tidy”. But do you actually know what it does? It is one of those files that works silently in the background, and some developers never stop to think about it. The “go.sum” file is one of those files you never really interact with directly, but it
Introduction "The best developers have always built their own tools." — The cmux Zen This is the 54th article in the "One Open Source Project a Day" series. Today, we are exploring cmux. If projects like pi-mono or Warp are redefining terminal interaction logic, cmux is building a new "physical space" for the AI Agent era. It is not just another terminal emulator; it is a highly programmable te
I recently built a dynamic testimonials component for my project at Coloring Maker and wanted to give it a little extra "magic." This is how I did it. The structure is quite simple. We need a main wrapper that acts as our "sky" and a series of div elements that will become our hearts. It is crucial that the main container has the position: relative; and overflow: hidden; properties. This ensures
By RUGERO Tesla (@404Saint) Most recon write-ups focus on the finding. This one focuses on the process. The target here is a Supabase project I own. Controlled lab, no real user data. I gave myself only what an attacker would realistically have: the project URL and the anon key sitting in the frontend bundle. No dashboard access. No schema knowledge. No tools beyond curl and a small Python script.
Ever wondered why you wake up feeling like a zombie despite "sleeping" for eight hours? Obstructive Sleep Apnea (OSA) is an invisible killer, a condition where your breathing repeatedly stops and starts during sleep. While professional sleep studies (polysomnography) are expensive and invasive, we can leverage Edge AI, Whisper.cpp, and the power of the Raspberry Pi to build a high-performance, pri

When we talk about Data Visualization and Dashboards, enterprise tools like Tableau or PowerBI often dominate the conversation. However, for Data Scientists and Developers, these GUI-based tools can feel restrictive. What if you need complex machine learning integration, custom UI logic, or automated CI/CD deployments? Enter the holy trinity of Python visualization tools: Streamlit, Dash, and Boke
