Instead of doing another Freeletics workout this week, I took advantage of the great weather outside and challenged myself with some uphill biking. It definitely pushed me to my limits, but it was worth it! And it worked, even though my bike only has eight internal gears.

Today, after the daily standup (without standup though), I went to pick up my girlfriend’s exam paper. But instead of using car sharing or the bus, I decided to go there by bike. This time with my older city bike. Faster than the bus, cheaper than car sharing. And it was a nice break from work. Hurray for flextime and working from home, which makes this possible for me!

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.

I couldn’t sleep anymore, so I decided to do a little bike tour. It’s so quiet in the morning and I saw some new places in this town and its surrounding. Tomorrow I plan to do a longer trip again.
