I spent $100 benchmarking LLM providers on a weekend CTF

from the self-post dept.

This past weekend, I decided to test out a cli tool I've been building to help me do source code reviews _faster_.I figured the best environment for such a tool would be a Weekend CTF event. I like web challenges since you get a nice dump of source code, as well as a Dockerfile or docker compose setup for how to run everything locally. Usually, I can complete 2-3 Web challenges before I get...

Show HN: Copilot's semantic code search, now as a remote MCP

Posted by wwdmaxwell on Wednesday December 03, 2025 @12:27PM
from the show-hn dept.

GitHub semantic indexing seems locked to Copilot via the GitHub web interface. I’ve found it helps for the odd question here and there.However I wanted that same codebase-awareness in Cursor, Claude Desktop, Cline, etc. — especially for private repos. So that I could stop cloning repos just to ask questions.I created a remote MCP server that runs on Cloudflare Workers.You can test it out...

I think Amazon uses an internal platform called Dynamo as a KV store, it’s different than DynamoDB, so im thinking the outage could be either a dns routing issue or some kind of node deployment problem.

Both of which seem to prop up in post mortems for these widespread outages.

Aside from being serverless. This is like elasticsearch but with a kind of built in redis-like layer, I think.

Show HN: MCP that adds RAG for private repos

I know there’s a bunch of these tools already out there for public sources of info. I built this tool because I was getting frustrated by having to clone repos of libraries/APIs I'm using to be able to add them as context to the Cursor IDE (so that Cursor could use the most recent patterns). I would've preferred to just proxy GitHub search, but that seems to be limited to public repos via...

I only call provider APIs and try to include only devDependancies in my project.

Really helped my understanding of how apps work.

I built this tool because I was getting frustrated by having to clone repos of libraries/APIs I'm using to be able to add them as context to the Cursor IDE (so that Cursor could use the most recent patterns). I would've preferred to just proxy GitHub search, but I (maybe also GitHub) couldn't figure out how to get reliable results based on a query.

My next step is to add the ability to specify a tag/branch to search specific versions of code bases, I also need to level up a bit more on my understanding of optimizing converting text to vectors.

Re:Show HN: App to buy groceries online on Saturday January 30, 2016 @02:01PM (#11003185)
This is my first app in the apple store, it's for a business idea I started up while working for a Retail Real Estate Developer as a way to leverage their existing assets for ecommerce, rather than watch all their tenants shrink in size.

Hi, I'm sure many of you could probably blow this out of the water, but I'm pretty proud of this little app. This is my first app. Having graduated with a degree in Biology I decided to teach myself ruby on rails to put together a "news map" because I felt this was missing when I was looking for my first place to buy, and I wanted to get a vibe of a local area.
