  3. &lt;p&gt;For example:&lt;/p&gt;
  4. &lt;pre&gt;&lt;code class="hljs"&gt;
  5. $ gg commit This is my commit message
  6. ❌ file has formatting problems
  7. Commit failed and you did not use --no-verify.
  8. ? Try again but with --no-verify? (y/N)
  9. &lt;/code&gt;&lt;/pre&gt;
  10.  
  11. &lt;p&gt;(&lt;em&gt;see screenshots below where color makes these things more intuitive&lt;/em&gt;)&lt;/p&gt;
  12. &lt;p&gt;This is handy when you know that the &lt;code&gt;.git/hooks/pre-commit&lt;/code&gt; might be failing for a reason that is actually not a problem &lt;em&gt;after&lt;/em&gt; you've committed.&lt;/p&gt;
  13. &lt;p&gt;In a sample repo I have:&lt;/p&gt;
  14. &lt;pre&gt;&lt;code class="hljs"&gt;
  15. $ &lt;span class="hljs-built_in"&gt;cat&lt;/span&gt; .git/hooks/pre-commit
  16. &lt;span class="hljs-comment"&gt;#!/bin/sh&lt;/span&gt;
  17.  
  18. &lt;span class="hljs-built_in"&gt;echo&lt;/span&gt; &lt;span class="hljs-string"&gt;&amp;quot;❌ Rejecting all commits like an angry troll&amp;quot;&lt;/span&gt;
  19. &lt;span class="hljs-built_in"&gt;exit&lt;/span&gt; 1
  20. &lt;/code&gt;&lt;/pre&gt;
  21.  
  22. &lt;p&gt;And when I use &lt;code&gt;gg commit ...&lt;/code&gt; this happens:&lt;/p&gt;

It dates back years. Most things are about technology but I also have a popular &lt;a href="/plog/blogitem-040601-1"&gt;blog post about finding song by lyrics&lt;/a&gt; which gets the lion share of the traffic.&lt;/p&gt;
  25. &lt;p&gt;I have implemented my own analytics of incoming traffic:&lt;/p&gt;
  26. &lt;ol&gt;
  27. &lt;li&gt;Every request that comes to the backend server gets logged in PostgreSQL  &lt;/li&gt;
  28. &lt;li&gt;When you view any page, an async XHR request is made and that's also logged in PostgreSQL&lt;/li&gt;
  29. &lt;/ol&gt;
  30. &lt;p&gt;Most traffic terminates at the CDN. Most likely, when you're reading this page right now it never renders on my server but is served straight from the CDN, but it will send an XHR request to my analytics backend, which in a sense becomes a measure that you're in a real regular browser that supports JavaScript.&lt;/p&gt;
  31. &lt;p&gt;One thing I noticed is that the request &lt;code&gt;User-Agent&lt;/code&gt; of the incoming requests that come in, appear to be some sort of bot that is &lt;em&gt;not&lt;/em&gt; Googlebot, which &lt;em&gt;used&lt;/em&gt; to dominate the traffic on my blog.&lt;/p&gt;
  32. &lt;p&gt;&lt;a href="/cache/ed/5a/ed5ad8259eedf0b173d5e63f82152b77.png"&gt;&lt;img src="/cache/ed/5a/ed5ad8259eedf0b173d5e63f82152b77.png" alt="Bot Agent Requests" width="100%"&gt;&lt;/a&gt;&lt;/p&gt;
  33. &lt;p&gt;Notables:&lt;/p&gt;
  34. &lt;ul&gt;
  35. &lt;li&gt;Claude's bot makes a ton of traffic!&lt;/li&gt;
  36. &lt;li&gt;OpenAI appears to have two bots ("gptbot" and "searchbot") and it's large&lt;/li&gt;
  37. &lt;li&gt;What on earth is that Facebook crawler doing? Is it crawling for training Meta's LLMs?&lt;/li&gt;
  38. &lt;li&gt;What is this Amazonbot and why is it making as much traffic as Googlebot?&lt;/li&gt;
  39. &lt;/ul&gt;
  40. &lt;h3 id="javascript-or-not"&gt;&lt;a class="toclink" href="#javascript-or-not"&gt;JavaScript or not&lt;/a&gt;&lt;/h3&gt;
  41. &lt;p&gt;At the time of writing this, I had only recently started tracking the &lt;code&gt;User-Agent&lt;/code&gt; of pageviews so I can't compare historical numbers. But generally it seems only ~1% of pageviews is by a bot user agent, whereas direct server-side traffic to the server, ~66% is from a bot agent.&lt;/p&gt;
  42. &lt;p&gt;&lt;a href="/cache/84/88/8488c0c71cb1ee540c6497984c243012.png"&gt;&lt;img src="/cache/84/88/8488c0c71cb1ee540c6497984c243012.png" alt="Is bot in pageviews vs requests" width="100%"&gt;&lt;/a&gt;&lt;/p&gt;
  43. &lt;p&gt;That means that a lot of the bots don't render the page with JavaScript. Or rather, perhaps they do but they have some provision in there so as to not trigger XHR requests to my analytics (which is implemented with &lt;code&gt;sendBeacon&lt;/code&gt;).&lt;/p&gt;
  44. &lt;p&gt;The reason for the "-16.5%" drop was because I recently implemented a fix to redirect traffic that bypassed the CDN and went straight to the backend.&lt;/p&gt;</description><pubDate>Wed, 09 Jul 2025 13:07:48 +0000</pubDate><guid>http://www.peterbe.com/plog/bot-traffic-hitting-my-blog</guid></item><item><title>Native connection pooling in Django 5 with PostgreSQL</title><link>http://www.peterbe.com/plog/native-connection-pooling-django-5-pg</link><description>Enabling native connection pooling in Django 5 gives me a 5.4x speedup.</description><pubDate>Wed, 25 Jun 2025 21:36:32 +0000</pubDate><guid>http://www.peterbe.com/plog/native-connection-pooling-django-5-pg</guid></item></channel></rss>
