At the end of April I decided to add a statistics page. It started as an hourly heatmap and then grew into daily charts, monthly trends, crawler sources, and visitor loyalty tracking.

The ASCII world map uses the DB-IP free city-level database (8 million rows). Visitor IPs are parsed into coordinates, then density characters are drawn onto map.txt. Mainland China, North America, and Europe all cluster in different regions, with dense areas using # and @.

The stats page also includes a UA archaeology panel for old browsers recorded in the logs.

I added psutil for CPU, memory, disk, and uptime. If psutil is unavailable, a ctypes fallback is used. The stats page now shows live server status without SSHing into the box.

The guestbook now has 20 pixel-art emoticons. Click the bottom panel to open the list, or type [em01] through [em20] manually. Stored values are codes, and both the page and email render them as images.

The emoticon panel does not preload images by default; it is generated lazily so the initial page load saves 20 HTTP requests.

The guestbook form moved from scattered label/input elements into a single HTML table. Name, Email, Content, Show IP, and Submit all fit inside a 125px wide cell. The emoticon panel collapses to save space, and 1px borders replace the default 2px look.

Reply emails were previously sent synchronously, forcing users to wait for the message to send. Now mailer.py runs as a separate process and sends email in the background via stdin.

Guestbook messages with codes like [em07] are now converted to <img> tags pointing to server-hosted GIFs, so email recipients also see the animated emoticons.

The site logs are now consolidated under data/logs/:

data/logs/
├── access/          ← access logs (.log per day, old logs .gz compressed)
├── guestbook.log    ← guestbook operations and SMTP status
├── editor.log       ← editor actions and auth events
├── search.log       ← search query keywords and result counts
├── toolbox.log      ← tool usage records
├── build.log        ← build actions
└── error.log        ← cross-module errors

A shared logger.py module now powers all CGI scripts, so logs are classified consistently.
