DuckDB just released Quack: a client/server protocol over HTTP. Any DuckDB can serve (quack_serve()), any DuckDB can attach to it. DuckDB-Wasm included since it's plain HTTP on port 9494. Some fun stuff : - A browser tab talking directly to a DuckDB server somewhere on the internet - Local-first...

We're excited to announce duckdb-skills, a DuckDB plugin for Claude Code! We think the embedded nature of DuckDB makes it a perfect companion for Claude in your local workflows. The skills supported include: + read-file and query – uses DuckDB's CLI to query data locally, unlocking easy access to any file that DuckDB can read. + read-memories – a clever idea to store your Claude memories in DuckDB and query them at blazing speed. These are powered by two additional skills: + attach-db – gives Claude a mechanism to manage DuckDB state through a .sql file linked to your project. + duckdb-docs – uses a remote DuckDB full-text search database to query the DuckDB docs and answer all of your (and Claude's own) questions.

This Tuesday, we announced Quack, our new protocol that turns DuckDB into a client-server database. Watch Hannes' talk, recorded at the AI Council, where he explained how Quack works in practice, what stack it's built on, how it performs, and what our long-term ambitions are.

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.

Let Postgres own the Iceberg catalog and delegate analytics to DuckDB. The result => transactional lakehouse updates with fast analytical queries. This isn’t a concept. It’s exactly what pg_lake delivers today. pg_lake combines a set of extensions and components that let you query and modify Iceberg tables (and other lakehouse formats) directly from Postgres. DuckDB is used to accelerate analytical queries and runs in a sidecar process called pgduck_server, which communicates with Postgres during query execution. How it works (diagram below): 1. An application sends a query to Postgres to calculate unrealized PnL (Profit and Loss) for the Disney ticker. 2. Postgres parses the query and identifies the part that computes the average price from historical lakehouse data. 3. That part is forwarded to pgduck_server for accelerated execution. 4. pgduck_server delegates execution to DuckDB, which queries the lakehouse (reusing cached data if available). 5. DuckDB computes the average price and returns it to Postgres. 6. Postgres joins the result with local portfolio data and computes the unrealized PnL. 7. The final result is returned to the application.

instant-feedback SQL editing aka "query-as-you-type" uses DuckDB's AST, duckdb-wasm for local-first caching, and MotherDuck as the backend Still early, but should enable arbitrary scale and still retain a near real-time feel while writing ad hoc queries! Bye bye run button 👋

What is HTTP Downgrading, why use it, and how does it work? HTTP/2 is default for most web apps these days, however, it's not uncommon for backend servers to still use HTTP/1.1 causing parsing mismatches between frontend and backend. And that's where HTTP downgrading comes in! But what is it? HTTP downgrading is the process of forcing a request to be processed under HTTP/1.1 instead of HTTP/2. This allows you to manipulate how the frontend and backend servers interpret requests and exploit vulnerabilities unique to HTTP/1.1 parsing such as Content-Length Transfer-Encoding (CL.TE) attacks. How to downgrade HTTP/2 to HTTP/1.1 using Burp Suite 1️⃣ Open Burp Suite and Navigate to Proxy → HTTP History 2️⃣ Locate the request that is currently using HTTP/2. 3️⃣ Send the Request to Repeater 4️⃣ In the Repeater tab, open the "Inspector" panel → Request Attributes → Protocol 5️⃣ Change HTTP Version to HTTP/1.1 6️⃣ Click "Send" in Repeater. If successful, you should receive a valid response, confirming the server accepts HTTP/1.1. And that's it! You've just downgraded the HTTP protocol and confirmed that the frontend server accepts HTTP/1.1! 🥳 You are now ready to smuggle requests! If you want to learn how to exploit this, we've got a Web Academy Lab you need to check out: Thanks for reading! #requestsmuggling #cybersecurity #BurpSuite #hacking #infosec

What if you could search 50M satellite image embeddings with no server, no database, and no API? Part 2 of Caleb Robinson and my series on Compressing Earth Embeddings is live at We binarized the global Clay v1.5 Sentinel-2 embeddings from 183GB → 7GB and built TerraBit — a retrieval demo that runs with zero backend. DuckDB-WASM, cleverly partitioned GeoParquet on S3, and brute-force Hamming in an in-memory index makes the experience feel too good to be true. If you also wondered how Google's TurboQuant fares on compressing earth embeddings -- don't worry, we got you covered in the blog -- hint: TurboQuant int4 is a solid choice

Cursor now has a built-in web browser. You can say "start my app" and it will run the dev server in a terminal and then navigate the browser to localhost:3000. It can take screenshots of the page for iterating on design, and you can send DOM elements to the agent with prompts!

So here is new local privilege escalation zero-day I discovered, not patched yet too :). In simple terms, if you have a service like RDP that exposes an RPC server, there many system services running as SYSTEM connect to it as RPC clients. If that service is turned off (RDP is off by default), it seems that any other process in Windows can expose the same RPC server using the same endpoint. Now all the RPC calls from that SYSTEM processes will come to this fake server and If the process that deployed the server has SeImpersonatePrivilege, it can escalate to SYSTEM by impersonate the RPC client. In the white paper below, I describe five exploit paths you can abuse. However it's architecture problem and maybe there are more. It's Not A Potato
