Walking in the sunny park is like balm for the soul. 😌

Hello, little deer! 👋

Before going to sleep, a quick walk around the block. 🌔

It took me so long to find the cause of a memory leak in GoBlog. I thought it was smart to use a cache for prepared database statements. But I didn’t read the documentation and didn’t know that prepared statements need to be closed when they are no longer needed to free up the allocated resources. 🤦‍♂️ I finally fixed it by removing the prepared statement cache altogether. Less code, fewer problems in the future, and the cache wasn’t much of an improvement anyway. I also learned about the usefulness of memory profiling.

I have a question for the IndieWeb community: What can we do against Webmention spam, except filter it out, when it fails validation? I receive hundreds of invalid Webmentions a day, and even using a filtering DNS server doesn’t seem to help much. But I also don’t want to waste network traffic to access all those spam sites. Is there any good block list I can check first before doing the request for validation? I thought about Akismet, but the API has no such option to only check the submitted URL.
