Recently, when using my beloved Niz Plum 66 keyboard, I ran into a strange bug.

In Bluetooth mode, the left Option key stopped working. Since my Hammerspoon setup and many other app shortcuts use it heavily, I could occasionally use the right Option key as a temporary substitute, but that was never a real solution. My work efficiency dropped a lot.

I am not sure how this bug was introduced. It was probably around the time my Mac started connecting to two external monitors.

A historical guide to automatically deploying paired Hexo blogs with Travis CI, GitHub tokens and a deployment workflow.

The solutions count colours on a tree, search bicycle states, reconstruct volunteer counts backwards, and use DP for stack-or-queue security choices.

Weekly Contest 259 follow-up solutions for operation simulation, array beauty, square detection and repeated subsequences.

The first English contest-summary post, marking a shift from more than one hundred Chinese recaps toward international interview practice.

How I created a separate English Hexo blog from the Chinese site, configured deployment paths, and linked the two versions.

A contest record with the first three tasks completed, two retries on the third task and the fourth left unfinished.

Four solutions enumerate ordered quadruplets, count weak characters, use DP to visit every room, and connect prime-factor components for GCD sorting.

Three contest solutions find an extrema GCD, a missing binary string and a closest row sum; the fourth records giving up and consulting a solution.

Four solutions test substrings, alternate high and low values, maximize a non-zero product, and use union-find to reconnect a flooded grid.
