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.

You're probably sick of me saying "B-tree" but these impact SO MUCH of database performance. They're used all over the place in Postgres, MySQL, and SQLite. This week I broke down B-tree lookups and how the page cache makes lookups faster.

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 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

You can connect your Supabase database via MCP server to Cursor! The Cursor agent can get the schema and any data from your database through the official Postgres MCP server! This helps Cursor understand your database better when it needs to modify it to add a new feature!

In 1964, Che Guevara enters the CBS News building with his signature, confident walk and leaves with the same undeniable presence, drawing all eyes on him. This is not just someone walking into a building, it is a rare moment that reflects the spirit of an era, the stance of an ideology, and how one person can command the scene without saying a word. Every step he takes, every look, every detail in his posture is part of the aura that turned him into a global symbol.

Here's some accidental mathematical art in Excel. Each cell is a²b-b mod c where b is the column, c is the row, and a varies from 1 to 30. I put a heat map on the cells (small=red, big=green) and noticed the beautiful patterns.

AGI. This Texas company is building it and has a very different approach than I've seen from others. This is Peter Voss's fourth AI company. He talks me through AGI. Is why I say it's a tiny database. Learn more about his company:

THIS CHINESE DEVELOPER TOLD A TINY AI DEVICE "I NEED A CAR CONTROL PROGRAM" - AND IT WROTE THE CODE, FLASHED THE HARDWARE AND LIT UP THE LEDS IN ONE SHOT small white screen showing "listening..." - he speaks the command out loud - the device hears it, writes the firmware, flashes the Raspberry Pi Pico and the red LEDs fire up in sequence no keyboard, no IDE, no Stack Overflow - just talking to a device that understands what he wants and builds it the breadboard on the desk is the hardware - the tiny screen in his hand is the AI that programs it - voice in, working electronics out he vibe coded the entire control system by describing it - the AI handled every line of MicroPython, every GPIO pin assignment and every LED pattern what used to require an electronics degree and a week of debugging now takes one sentence spoken out loud the people still manually writing firmware are one voice command behind

Janelia is built for this moment. Starting today, we're taking on 2 big bets: cracking how a vertebrate brain generates behavior & building AI-in-the-Loop — a new way of doing biology. Tiny transparent fish + 1 of neuroscience’s biggest questions? Let's go

🚨 CUNY Law Professor Says NYPD Gang Database Must Be Abolished, Calls It a “Weapon” This is CUNY School of Law professor Babe Howell, speaking as part of the G.A.N.G.S. Coalition, arguing that the NYPD gang database should not be reformed but abolished outright, saying, “We must erase the database. Entirely it must be abolished.” Howell makes clear this is a total rejection of reform, adding, “There is no safe database” and “There’s no reforming this.” She then goes a step further, calling the database a “weapon,” saying, “This is not a safe tool… rather weapon. A weapon to be left in the hands of the NYPD.” She also tries to frame gang database abolition as an affordability issue, claiming that “part of affordability” means being able to get to school or work without being stopped, debriefed, or forced out of your way.
