July 19, 2025: Weekly Note 2025/05

Kaalu The Fifth leg pain is better than last week. Fish oil and supplement is working. I need to add fish/fish oil to her diet. Her mother is Labrador, and Labrador are apparently susceptible to arthritis.
Ookie is enjoying her time at day-care. Last Friday, she played really hard at day care. Tired, she slept through the night without waking up a single time.
Nothing much to report from work this week — a good thing, I guess. Every time I change the schema of the database, the Rust code stops compiling. I am using SQLX which checks type against database schema at compile time. So I get to know the issue before it is deployed. I have a lot of respect of SQLX (and Rust) these days. Also, the PHP8 codebase doesn’t have a good test coverage yet. I need to spend a week or two to write e2e tests.
I was doing some analysis for a friend which may be very useful later at work as well. I learnt a few things about tSNE, one of them is How to Use t-SNE Effectively. The amazing book Foundation of data science by Blum, Hopcroft, Kannan has a chapter on clustering, where tSNE has been discussed extensively.
I’ve been making notes from the book A Philosophy of Software Design — John Ousterhout here in this database . I’ll publish a few notes on LinkedIn over the next few days.
I am as surprised as anyone would be, learning about Data alignment for speed: myth or reality? – Daniel Lemire’s blog. Apparently, it doesn’t matter if you align your data or not!!
