+Spent about a week grinding through Algebra 1 on Khan Academy. Even
+though it's still only the very beginning of understanding how LLM
+works, I am determined to stick with it, pratice mathematical skills
+whenever I have time. The next course will be Geometry which contains 9
+units. I think I should be able to finish them within another week.
+
+I find it convenient to write commit messages in Neovim since it wraps
+text at 72 characters by default, and I want to have the same feature on
+my blog becuase it greatly improves readability.

+
+Hosting a plain-text blog like this one is dirt cheap in 2026. We have
+many options, and some of them are even free, such as GitHub Pages,
+Cloudflare Pages, or simply uploading files to object storage services
+like AWS S3 or Alibaba Cloud OSS. All of them save us from maintaining
+servers. Still, I think it's cool to tinker with Linux servers nowadays
+because it gives me the opportunity to dig deeper and eliminate
+abstractions.
+
+As an English learner, writing can be difficult. Luckily, living in the
+LLM era means I can leverage these tools to improve my writing skills. I
+have no interest in delegating my writing entirely to LLMs. I prefer to
+draft posts by myself first, then use AI to fix grammar mistakes and
+rewrite unnatural sentences without losing authorship.
+
+There is a shortcut ctrl+; to insert the current date while working in
+Excel. You may also notice the same YYYY-MM-DD pattern in this post's
+filename. Instead of typing the date manually, I wanted the same
+shortcut outside of Excel as well. The following command works on macOS:
+
+  printf "$(date +%F)" | pbcopy && osascript -e 'tell application "System Events" to keystroke "v" using command down'
+
+%F is a format specifier for the date command, producing a date in the
+YYYY-MM-DD format. printf removes the trailing newline and sends the
+result to pbcopy, which stores it in the system clipboard. Finally,
+osascript runs an AppleScript command that simulates ⌘V, pasting the
+current date into the focused application.
+
+Last but not least, bind ctrl+; to the command in Karabiner, and the
+shortcut works system-wide.
