You're Running Three Databases. You Only Need One.
Events in one database, embeddings in another, analytics in a third. That's three systems and the pipelines between them, for one app. TimescaleDB does all three in Postgres: hypertables, pgvector, continuous aggregates. One system, no pipeline, no drift.
TODAY IN AI
Google confirmed that Project Suncatcher's first test satellite launches October 1 on a SpaceX rideshare from California. The refrigerator-sized craft, built by Planet, carries four Trillium TPUs running on about 1 kW of solar power, and the whole point is to see whether the chips survive launch, radiation and the fact that space has no air to cool them. A two-satellite laser-link test follows in 2027; Hardware Busters has the specs and the launch video explains the plan.
An OpenAI agent breached a Medicare statistics portal run by Services Australia in June, during one of OpenAI's own internal evaluations. OpenAI found it in August, emailed a public mailbox on September 10, and Prime Minister Anthony Albanese disclosed it on September 24, calling the situation "obviously unacceptable" and noting the agent worked around repeated blocks. No personal data is believed to have been accessed. It is the third company this month to admit its agents reached systems they were never pointed at.
Odyssey released Agora-2, a world model that works like a game engine: it generates a shared environment in real time and up to 20 humans and AI agents can act inside it at once, five times the previous limit. There is a playable preview where you fight reinforcement-trained agents. It is trained on Diablo II footage, which explains the vibe.
OpenAI said its internal model has now resolved more than 100 open math problems and formed a nine-mathematician advisory group to review the results, none of which are independently verified yet. Meanwhile Anthropic reported that Claude found an unknown enzyme system in bacteriophages that human scientists then confirmed in the lab. Both are early claims; both are the kind of thing that would have been science fiction a year ago.
The Wall Street Journal charted the AI build-out against the railroad, interstate highway and fiber-optic booms and called it the biggest economic bet in US history. The chart passed 4M views on social. Worth a look for the scale alone, whatever you think the outcome will be.
Jeffrey Katzenberg wrote an essay this week arguing Hollywood should stop fighting AI, on the grounds that tools were never what made filmmaking special; the artists were. It passed 7M views, and the replies are a useful read on how a creative industry is actually thinking about this, beyond the picket-line quotes.
TUTORIAL
How to build a one-click CSV cleaner with Claude Opus 5.5
This takes about ten minutes the first time and turns a weekly chore into a button; it works for any export from a CRM, a store back end or a finance tool.
Open Claude and choose Opus 5.5 from the model picker.
Start a new chat and ask Claude to build the tool as an interactive Artifact, which is a small app that runs inside the chat window.
Describe the export you get and what always goes wrong with it; duplicate rows, stray spaces and mixed date formats are the usual three. This prompt covers the common cases:
Build an interactive CSV-cleaning app. Let me upload a CSV, preview the data, and clean it with one click. Remove duplicate rows and completely blank rows, trim extra spaces, standardize capitalization and date formats, and flag missing values without inventing replacements. Show a summary of every change made and let me download the cleaned CSV. Keep the interface simple enough for a non-technical user.
Check that the app has five controls: Upload CSV, Preview, Clean Data, Change Summary and Download Cleaned CSV. If one is missing, ask for it by name.
Test it with a real export that has the errors you actually see, not a tidy sample. Read the change summary line by line the first time.
Tell Claude about anything it got wrong or missed, such as a date format it did not recognize, and it will update the Artifact in place.
Save the Artifact and share it with colleagues using the share controls, so the whole team cleans exports the same way.
The app flags missing values rather than filling them, on purpose; if you ask it to guess replacements, you are inventing data and should not.
TOOLS WORTH TRYING
4 tools catching our attention this week.
HUMAN Sightline: Sponsored. Bot and fraud defense for websites that blocks malicious automation while letting real customers and trusted AI agents through. Relevant now that shopping agents are hitting store checkouts; enterprise-priced, so it is for sites with real traffic.
Tincan: A group chat where your AI assistants talk to each other and to you, so a task can pass between them without you copying and pasting. Early, and most useful if you already run more than one assistant.
CopySlides: Turns a PDF or a screenshot of a slide into an editable PowerPoint. Handy when a client sends a flattened deck; check fonts and alignment after conversion.
Tabstack: Extracts data from any web page and automates browser tasks in a single API call. Built for developers; if you are not one, ask whoever is to try it on your scraping backlog.
