Using Expo with real-time synced SQLite means that instead of having to: • manage network requests • handle loading states • implement retry logic • orchestrate state management between your local cache and remote data You just write queries™

Part 1 of 12: building a tiny SQLite-style database in C from scratch. Today is the REPL skeleton: the db > command line, getline, .exit, EOF handling, and the loop every future parser, row store, pager, and B-tree feature plugs into. This tiny command shell becomes a database.

Here is my Vegas DefCon presentation from last week on how to hack the Dominion Voting machines. There is a unprotected SQLite database on the ICX voting machines that can be altered. It also stores the encryption keys in plain text.

Database table size impacts performance in more ways than one: a) B-tree depth. Using 8k pages and a 16b uuid: 1 level = ~370 rows 2 levels = ~138k rows 3 levels = ~50m rows 4 levels = ~20b rows The lookup cost on a table with 100k rows is not the same as one with 1b rows. This can apply both to the table itself (MySQL cluster index) as well as the indexes. Sometimes a single query requires many of them. b) Small table → fits in RAM → fast reads. The larger the table, the more likely to read from disk plus churn the cache. c) # of indexes. Each adds maintenance overhead for insertions, and for Postgres vacuum overhead as well. Keep an eye on this! It's useful to take regular stock of your tables + indexes. Clean bloat. Remove unused indexes. Partition if needed.

So you can just give it a postgres URL (or sqlite db file) and it will just... explore it and offer to build things. Even with a crazy nonstandard (from Ecto perspective) database. The search bar crashed, I sent the logs to the agent, and boom realtime searching

I promised a longer video on how to build a full-stack ICP app, powered by SQLite. Here it is! This is a nose to tail walkthrough, we look at database migrations, automatic input validation, DTO objects, performant frontend queries using Tanstack Query and lots more. Links to demo app, libraries and YT video in the responses. 🌱

Epicenter (epicenter) is building a database for your mind. They're designing a Svelte ecosystem of apps sharing a local memory: a folder and SQLite file. Open-source, open-format, and fully yours. Congrats on the launch, Braden Wong!

So you forgot how you fixed that bug the other day. 😬 No worries. GitHub Copilot CLI remembers. With its local SQLite database of your session history (and a full-text search index), you can instantly pull up context from your previous work. ✅ Install Copilot CLI and save brain space. ⬇️

The 1.4 release of DuckDB supports using a DuckDB database to serve vector tiles! Of course, I had to try this out in R. Check it out: all 242,000 US Census block groups dynamically served as vector tiles from a DuckDB database, displayed on a MapLibre map from R in Positron.
