This week note covers the week of 22nd–28th December.

  • It is the week of Christmas holidays. Though majority of Indians are not christian, a lot of us still take vacations during this period. The stores and malls in Bengaluru put on decorations and play Christmas music. The weather has also been great. I took half of the week off just to cool down at home.
  • The big event of this week for me was Tanvi’s Christmas party. It must have been a decade since I went to a party this big. It was a bit awkward being the oldest person in the room, but I had a lot of fun. We talked about many random topics and had delicious food brought by everyone. I’m looking forward to more parties in future.
  • My walking pace has improved to almost pre-burnout times. I’m making it a point to walk two km every day, mostly at the night when the weather is slightly chilly.
  • It’s a great time to drive in Bengaluru right now. The traffic is almost nonexistent and the roads are empty. We went out on multiple days this week, and I was able to drive in the 4th gear!
  • We decided to go to the newly reopened The Hole in the Wall Café on Christmas morning for breakfast, but upon reaching, found it closed. Then we randomly wandered into Mitco Coffee. It was … not great. We finally made it to The Hole in the Wall Café on Sunday. We had sandwiches and waffles for breakfast. It was as good as ever. Despite the remodeling, their food menu and taste remains unchanged.
  • I wrote a note about all the things I worked upon in this website in 2025. On that note1
  • I spent most of my free time trying to debug the high memory consumption issue in my static site generator, which I introduced when I added support for finding and displaying similar posts in post footers. The generator was taking almost 5 GB memory to run, causing frequent OOM kills. I deduced that the issue is because the GHC garbage collector is not able to keep up pace with the large amount of garbage generated by the text similarity computation. I tried various things like caching more/less data, computing more/less, using different data types (ints, floats, doubles), increasing/reducing concurrency. Nothing worked well enough. Finally, I stumbled upon an article Lessons in Managing Haskell Memory, which advised using Compact Regions. That and some clever use of Shake Oracle caches reduced the memory usage to 3 GB. It’s not great, but I’m out of ideas for now.
  • No books read this week, but I did watch a lot of TV shows. Wife and I continued our watch of Interior Chinatown. We also binged many episodes of Barakamon. On my own, I stared watching The Ancient Magus’ Bride, and I’m enjoying it a lot. It’s a slow burn, but I am happy to watch a non-Isekai fantasy anime at last.
  • This week I rearranged my feeds using the permaculture principles. I used to have them categorized by topics like Compilers, Database, Hardware, etc, but I found that I rarely used the categories to browse the feeds. The aforementioned article really resonated with me. It took some time, but I put all my active feeds in these new categories:
    The old categories are still there; I’m slowly migrating my feeds to the new ones. But this new categorization has been immediately useful to me. Since the categories are ordered by priority, it is easier for me to go through them.
  • Some interesting links from the internet for this week:

That’s all for this week. You can subscribe to the feed of my week notes for updates.
