That's wrong. GPT 5.6 Sol looks to have the same price as GPT 5.5, apart from a new pricing fee for cache writes. Fable 5 is $10 input / $50 output.

New comment by celesian in "MCP server for Ghidra"

celesian — Thu, 27 Mar 2025 03:26:27 +0000

This is very cool but it would be nice to have more features on the MCP server, such as arbitrary read and write of programs. For example, I was working on a self-unpacking CTF challenge which XORed instructions. It would be nice to have it be able to read the values at the addresses it xored.

New comment by celesian in "Show HN: I've created the fastest open-source DNS bruteforcer using XF_ADP"

celesian — Thu, 20 Mar 2025 21:55:10 +0000

Hey HN! I've done a lot of work with querying large amounts of DNS scanning recently for my own projects, and I've found that the current available tools (massdns, dnsx, zdns) were lackluster in the performance and accuracy aspect.

Recently, I've learned about XDP and AF_XDP, which allows user-space programs to have a fast-path through the kernel and skip a large chunk of networking done by the kernel. This allows us to directly interact with the network interface TX queues, and send a lot of traffic very fast.

I initially started to do this because I was curious if it would work or not, but eventually I saw that it worked too well, so I polished it a little bit and released it as open-source.

Happy to answer any questions.

This reminds me on how Spotify's bug bounty program keeps receiving vulnerability reports about Shopify, and how Shopify keeps receiving vulnerability reports from Spotify. This went so far that they had to explicitly put the other company's domain as out of scope on their bug bounty policy.

I think the documentary about "pixo" is pertinent here, "pixo" is a political manifestation. It is meant to be ugly. https://www.youtube.com/watch?v=skGyFowTzew

I guess you do kinda shake and move around the muscle of your hands when you're running.

I mean, your IP is being crawled by random bots dozens of time per day, what's the difference between that website and the traffic your IP gets already?
