Self-Study in July 2024

There’s a fascinating Rust library, loom, which can be used to thoroughly test lock-free data structures. I always wanted to learn how it works. I still do! But recently I accidentally implemented a small toy which, I think, contains some of the loom’s ideas, and it seems worthwhile to write about that

Re: Do people IRL know you have a blog?

No one else has anything invested in this. No one cares if you do it, or don’t do it. To the world this pursuit is just your cute little hobby.

There’s a constant tug of war between wanting to be professional and wanting to be cool online. Sometimes those things overlap and sometimes they don’t. And sometimes the folks who have the opportunities to make a weirdo website are doing so because they’re not financially dependent on their website selling a service or landing a new gig. Their economic livelihood isn’t at risk if someone is turned off by the strange fonts or experimental navigation on their website.

A discussion he had with his wife about having a blog prompts the question of what is the purpose of the personal blogs.

The author does not mind if they are useful to other people or not; it’s not a source of income.

Another comment: My blog is primarily a way for me to clarify my thoughts on a topic by writing about it. Once that is done, the amount of effort required to post those thoughts is small, so why not do it?.
