The classic meme from Linux founder Linus Torvalds Talk is cheap. Show me the code. has evolved into: Code is cheap. Show me the prompts. Original tweet:…
1 Prologue A while ago, I took a flight from Canada back to Hong Kong - about 12 hours in total with Air Canada. Interestingly, the plane actually had WiFi: However, the WiFi had restrictions. For Aeroplan members who hadn’t paid, it only offered Free Texting , meaning you could only use messaging apps like WhatsApp, Snapchat, and WeChat to send text messages, but couldn’t access other…
1 Preface I spent a weekend building a Telegram spam blocker bot based on Bayesian Algorithm @BayesSpamSniperBot ( https://t.me/BayesSpamSniperBot ). The project is open-sourced at: https://github.com/ramsayleung/bayes_spam_sniper 1.1 Telegram Telegram is a popular instant messaging application, similar to Snapchat and WhatsApp, with over 1 billion users. It supports many powerful features like…
1 Preface Malcolm Gladwell’s “10,000-hour rule” suggests that continuous investment of 10,000 hours of effort is sufficient to reach expert level in any field. Based on 20 hours of practice per week, this requires about 3 hours of daily investment, taking roughly ten years to achieve this goal. Since I wrote my first line of C code, more than ten years have passed. During this…
Developers usually use git blame in GUI tools like GitHub Blame or using GitLens blame in VSCode: Even though GUI tools is intuitive, but the Git CLI has much more powerful tooling for finding something closer to the real story behind your code. There are many scenarios that CLI is valuable, the first is ignoring the whitespace changes. For example, if you formatted your C++ codebase with…

1 Definition In computer science, a topological sort or topological ordering of a directed graph is a linear ordering of its vertices such that for every directed edge uv from vertex u to vertx v , u comes before v in the ordering. It sounds pretty academic, but I am sure you are using topological sort unconsciously every single day. 2 Application Many real world situations can be modeled as a…
