Telegram worries

Published on in 💭 Thoughts

Telegram was always my favorite messenger, as it provided a fast and user-friendly experience on multiple devices. But one and a half years ago, I already started doubting my decision to rely on Telegram.

Summer vacation ‘24

Published on in ✍️ Posts

A week ago, we returned from our summer vacation: This year, just like four years ago, when there weren’t many other options due to COVID, we went for 1.5 weeks to my grandmother’s vacation apartment in Lübeck-Travemünde.

After my bike tour on Monday, I first felt the usual exhaustion, but later that evening and night, more symptoms joined and showed me, that I, again (third time already this year), caught some infection. Nothing too bad, but it forced me to relax and recover the last two days.

Post-vacation bike tour

Published on in 💭 Thoughts

Today was my first workday after summer vacation, and with the weather being pleasant – not too hot, and no rain – I decided to finish work a bit early and go for a 39-kilometer bike tour through the surrounding area.

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.
