Every December I do Advent of Code and every January I try to keep the habit going on LeetCode. Never lasted more than a week. Too many problems, no reason to do this one today. So I borrowed the idea and built Daily Coding: one challenge a day, the same for everyone, all year. You solve it in the b
Article Summary: Droid ASC is a high-performance tool for Android reverse engineering and mobile security testing. It reduces memory usage by two orders of magnitude and eliminates disk caching compared to the traditional jadx decompiler, achieving second-level decompilation and millisecond search.
The Evolution of Terminal Search: Meet zvec-grep (zg) For years, ripgrep has been the undisputed champion of developer code search—offering instant, multi-threaded regex matching across massive directory trees. Yet traditional grep tools share a fundamental limitation: they require the user to a
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
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
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
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
Your agent can thrash for forty turns and still be stuck. Busy is not progress. In this lab you fail unless every iteration names a remainder and that remainder strictly shrinks. I do not grade the model's vibe. I grade a number that goes down. Why this lab, and why now? Coding agents look product
Originally published at bitsar.net. Twelve pods, one Redis, and @Cacheable(sync = true) on the method. I read that as a protected endpoint. It coordinates callers inside one JVM, so a cold key was still twelve calls to the same slow dependency. This is what I found when I went looking for the clust
Messy CLIs fail at the process boundary, not helpers. Snapshot three channels before extracting one flag parser. Exit code, stdout shape, and stderr tokens form the contract. Why the process boundary comes first A flag extract looks local inside the editor. The process contract is not loc
A beginner-friendly, real-world walkthrough of diagnosing and fixing networking issues in a Linux Azure Function App running on Elastic Premium. When an Azure Function App doesn't even show its runtime version, it is very easy to start looking at the application code. But what if you haven't dep
Cross-Chain Bridge Risk Assessment: Tether Gold Target Protocol: Tether Gold (TVL: $3078.3M) Cross‑Chain Bridge Risk Assessment – Tether Gold (XAU‑T) Prepared by: Senior DeFi Security Researcher – Smart‑Contract Auditing Team Date: 12 September 2026 1. Executive Summary
The hype around AI coding agents has reached a point where "I use Cursor" or "I use Claude Code" is becoming a default answer in developer conversations. But the gap between what people claim works and what actually works in daily workflows is still wide. I spent 30 days using multiple agents on rea
I prepared a small Laravel playground with a shipping price bug and a deliberately long commit history to demonstrate automated regression hunting with Pest and git bisect. The endpoint should charge €5.90 for a domestic parcel weighing up to and including one kilogram. At exactly 1000 grams, it ret
You open the repository. Nobody who wrote it still works here. There are no tests. The one README file describes a feature that got deleted two years ago. And something is broken in production. Welcome to the job. Debugging code somebody else wrote is one of the least talked-about skills in softwa
came back to a backend service i wrote 18 months ago and i genuinely cannot tell what i was thinking. the logic is technically there but the variable names are confusing, there are like 3 comments total, and there's a function called process_data that does 5 completely different things. at what poin
A few weeks ago I shipped the 1,000th production deployment of an application I built almost entirely through conversation with an AI. Not "AI helped me write some functions." I mean I didn't open the codebase. Every migration, every deploy, every rollback happened through a chat window talking to C
A budget alert tells a person that a limit is close. A hard spend cap changes what the workload is allowed to do. In a fintech leaked-key drill, that difference decides whether the incident ends in a bounded denial or an invoice you explain later. Short answer: use a hard cap as the enforcement bou
Hi everyone! I spent the last couple months (definitely not a weekend project!) experimenting with three.js and building a video meeting app where you can fly around and talk with others around you, collaborate and have fun together. It's second iteration of my solo passion project. I used three.js
Version 1.0.0 of brick/math has been released today. After more than a decade, 804 commits, 79 beta releases, and 590 million downloads, the API is now considered stable. By semantic versioning rules, future breaking changes will require a new major version. brick/math is an arbitrary-precision arit

![[showoff Saturday] I got hooked on Advent of Code and wanted it all year, so I built a site that gives everyone the same coding challenge every day](/storage/uploads/covers/2026/09/e5df4422-9496-4707-88e0-d4413f16137b.webp)
