If I need to query the db repeatedly (N times per second), isn't it more efficient (low latency and aws cost) to just download the db and run queries locally?

I got a Boox note air 2. It's an e-ink device/android tablet/e-reader/note-taking.

You can install any app on this device. I find it's acceptable to code with web-ides like replit.com. But my main usage is reading and note taking.

  1. I usually open about 30 to 50 tabs, and then my laptop becomes slow or it's difficult to navigate them.
  2. I decide to close some but find it difficult to choose which ones to close - they all seem important to me.
  3. I use onetab to close them all so if I need any of them I can get them back.

  1. Join a company (usually big) that has a culture of open sourcing softwares.
  2. Start an open source project you are keen on, and make use of the resource to grow the project/community/contributors.
  3. Quit with other core maintainers and start your own company that commercializes the open source project.

Sorry I didn't make myself clear. I was surprised because two databases from Alibaba are open sourced or to be open sourced.

Oh, what's going on here?

Great work! I headed to the context chapter and learned something I was not certain. But regarding the linked list (https://www.practical-go-lessons.com/chap-37-context#linked-...), since a context can be parent of multiple contexts, I feel it's more like a tree structure.
