Went from "V8 exploitation seems unachievable" to solving all 9 @pwncollege V8 challenges. Wrote a guide on getting into browser exploitation if you already have classic pwn knowledge. varik.dev/blog/v8/gettin…

Recently pwned NFTDRM on HTB - a QEMU escape ranked insane Wrote a post on setting up a proper debug environment for QEMU PCI device exploitation. No exploit spoilers. varik.dev/blog/htb/nftdr… #CTF #PWN #QEMU #HackTheBox

An exciting blog post exploring how the Cheat Engine works, from building it from scratch to using it in CTF challenges, and much more! Kudos to @D4RK7ET varik.dev/blog/cheat-eng… #cheatengine #rust #ctf

@aramiggs turns out it's a joke/reference about me, organized by bug bounty players.

🚀 Lantern now supports LLM calls in Postgres! Run adhoc queries: SELECT llm_completion('Summarize code', code) FROM files LIMIT 1; Or automate column generation: SELECT add_completion_job('files', 'code', 'summary', 'Summarize code'); lantern.dev/blog/llm-compl…

We're excited to announce managed @lanterndb on Ubicloud! lantern.dev/blog/ubicloud With this partnership, here's what you get: * With open source, powerful RAG (Retrieval Augmented Generation) AI apps * Better better price / performance than proprietary solutions * Usability and fast indexing features from Lantern * Deep Postgres and AI expertise, in one partnership

🚀 We’re excited to share that Lantern is now available on @UbicloudHQ ! You can access vector generation, LLMs, serverless indexing, and more. All in Postgres. All open-source. If you're building an AI app, we can help you simplify your infrastructure. ubicloud.com/blog/build-ai-…

we went to an @OpenAI x @ycombinator hackathon this week! @ngalstyan4 and i built an app to iteratively build postgres extensions - it generated a median aggregate function extension successfully :)

We built external indexing for pgvector in Postgres. External indexing offloads the resource-intensive index creation process to external machines to reduce the impact on database performance. Read the blog post from @D4RK7ET below 👇 lantern.dev/blog/pgvector-…

I built a site to browse the Postgres mailing list archives. It supports search using FTS from Postgres + vector search with the Lantern extension. I've been using it for testing but cleaned it up a bit to share 🙂 pg.lantern.dev

This is a very cool look at how pgvector indexes work, and they built an incredible browser based visual inspector for it with PGlite 🤯

Besides the deep dive we have built a JSON parser for HNSW indexes and interactively visualized index pages entirely in the browser using pglite. Check out the blogpost and play with the index parser yourself! #PostgreSQL #postgres #pgvector #hnsw #pglite

Did you know there are over 300 parameters used to configure a Postgres service? @ngalstyan4 covers some of the differences in default settings across Cloud providers. lantern.dev/blog/cloud-con…

Hybrid vector search = dense vectors + sparse vectors, combining semantic + keyword search to improve search results 🚀 We evaluated hybrid vector search with embeddings from Open AI, @JinaAI_ , and SPLADE using the BEIR framework. lantern.dev/blog/hybrid-se…

We respond to Pinecone's recent blog post comparing Postgres and Pinecone. We show that Postgres can outperform Pinecone in the same benchmarks Pinecone covered in their article. lantern.dev/blog/postgres-…

From hackathon to working implementation! Check out our blog post on how we managed to deal with the challenges of making dynamically loadable extensions to work inside Postgres in the browser (wasm) and found a compiler bug in emscripten during the process 🚀

Narek (@ngalstyan4) walks through some of the basics around reading, interpreting, and editing permissions in Postgres lantern.dev/blog/understan…

@catalinmpit Use postgres with @lanterndb for vector search instead of pinecone ;)

Just use Postgres for everything.

Client side path traversals are hot now ! So here is a story about @ProjectJupyter vulnerabilities chained with a chromium leak. blog.xss.am/2023/08/cve-20…

Narek Galstyan (@diqitally), Varik Matevosyan built an extension to @lanterndb, to perform postgres vector search in the browser. Letting anyone build and ship applications on top of LLMs and vector DBs - making trying a back-end as easy as trying a front-end
