I Built a Personal Second Brain with Markdown Files and Claude Code — Here's How

The Inspiration I saw Andrej Karpathy's viral post about using LLMs to build personal knowledge bases — no vector database, no chunking pipeline. Just markdown files, Obsidian, and Claude Code. The core idea blew my mind: Create a folder with raw/ and wiki/ subfolders Drop in source documents, articles, transcripts Tell the LLM to ingest the raw files and build wiki pages with relati...

I realized I was using AI wrong… so I built something to fix it

Hey everyone, I’ve been using AI tools like ChatGPT, Claude, and others for a while, and I noticed something frustrating: I was constantly switching between them trying to figure out which one actually gives the best answer. Sometimes ChatGPT was better, sometimes Claude was… but there was no easy way to compare without wasting time copying and pasting the same prompt over and over. So I decided t...

Does anyone else experience pretty severe social isolation in this career?

My team is fully remote. I’ve only 3 years of XP. This is taking a pretty negative toll on my mental health. I’ve tried so hard to get out & meet people in the city I moved to for this job. It hasn’t worked for me so far. I hate the feeling of spending all day alone with headphones in. I kind of feel like I’m going a little crazy if I’m honest. This isn’t the normal me. I think it’s the isola...

10 Signs of Burnout in Software Engineers

Burnout in software engineers rarely looks like a breakdown. It looks like a great engineer slowly going quiet — fewer ideas, slower responses, "I'm fine" becoming their default answer. By the time it's visible, it's usually been building for months. According to JetBrains' 2023 State of Developer Ecosystem report — based on 26,000+ developers worldwide — 73% of software engineers have experienced...

分布式事务完全指南：CAP定理与可靠消息的深度实践

在分布式系统日益普及的今天，事务处理成为了每个开发者必须面对的核心挑战。本文将深入探讨分布式事务的理论基础与实战方案，帮助你构建可靠的数据一致性系统。为什么分布式事务如此困难？传统的单机数据库事务依赖于 ACID 特性（原子性、一致性、隔离性、持久性）。然而，当系统扩展到多个节点时，情况变得复杂起来。核心问题：在分布式环境中，不可能同时满足 CAP 定理中的全部三个特性。 CAP 定理的启示 Consistency（一致性）：所有节点在同一时刻看到相同的数据 Availability（可用性）：每个请求都能在有限时间内得到响应 Partition Tolerance（分区容错）：系统在网络分区时仍能继续运行分布式系统必须在 CP（保证一致性牺牲可用性）或 AP（保证可用性牺牲一致性）之间做出选择。分布式事...

I built kerf-cli because Claude Code told me not to worry about cost

A few weeks ago I logged into Claude Code, typed /cost, and got back this: With your Claude Max subscription, no need to monitor cost. Two days later I had used 91% of my weekly limit in a single morning of work. I had no idea which session, which project, or which model was responsible. I tried ccusage (which is great) and it gave me totals — but I wanted to ask questions like "which of my pr...

The Commoditization Thesis: What Actually Happens When Software Gets Easy

The data is clear on what’s already happening. Labor’s share of GDP fell to 53.8% in Q3 2025 — the lowest in the modern BLS series back to 1947. Capital is eating labor’s lunch, and AI is accelerating it. Entry-level pressure is already visible: Stanford’s Digital Economy Lab found declines concentrated among 22–25 year-old workers in AI-exposed jobs such as software development, customer servic...
