Talk from SSW 2026.

Takeaways

SQLite is used so much because it solves more problems than it creates.

Example: video note

Fri, 28 Aug 2026 10:00:00 +0330

This is a starter video note. Copy it, or delete it once you add your own.

Use note_type = "video" and put the YouTube URL in source so the video embeds at the top. Headings like 12:40 make timestamped notes easy to scan.

Takeaways

The browser event loop is a queue: JavaScript runs one thing at a time, then picks the next callback.
Rendering and I/O are not the same queue as your JS callbacks.
setTimeout(fn, 0) does not run immediately; it waits until the current stack is clear.

Notes

01:15 — Call stack

JS is single-threaded. Each function call is pushed onto the stack and popped when it returns.

Example: book note

Thu, 27 Aug 2026 10:00:00 +0330

This is a starter book note. Copy it, or delete it once you add your own.

Use note_type = "book", creator for the author, and one heading per chapter. Set status to in-progress while you are still reading.

Takeaways

Reliability, scalability, and maintainability are the three reasons we bother with data systems.
There is no single storage engine that is best for every access pattern.
Replication and partitioning are separate problems; most systems need both.

Reliability means the system keeps working when things go wrong, not only in the happy path.
