Nested querying is not something that is standard for regular grammars, amongst other aspects introduced in this paper that implicitly require things like memory (again, not standa…

Comment #42257056
At what point do we drop the term "regular" expressions altogether for stuff like this? This is going to sound pedantic since I know that most popularly-used regex implementations …

Comment #37901769
Building off our last research post, we wanted to figure out ways to quantify "ambiguity" and "uncertainty" in prompts/responses to LLMs. We ended up discovering two useful forms o…

I think the author of this post probably meant to caveat that what we call "prompt engineering" TODAY might tend towards snake oil, but prompt engineering _doesn't have to_ be snak…

Comment #37474401
Interestingly we initially thought that prompt length would play a big factor in the performance of this approach. In practice, though, we discovered that it's actually not as big …

Great question - there are currently (likely) tons of limitations to this approach as-is. We're planning on testing this on more capable models (e.g: integrated gradients on Llama2…

Show HN: A surprisingly effective way to predict token importance in LLM prompts
We explored a novel method to gauge the significance of tokens in prompts given to large language models, without needing direct model access. Essentially, we just did an ablation …

Off the back of a napkin - the key should never be stored anywhere first of all. In the absence of keyring/keychain/etc., it'd be trivial to introduce a masterpassword implementati…

Comment #9798849
As addressed in the post - there are no mitigating factors in the scenario of accidental exposure. The lowest hanging fruit would be a dumb hashing function which uses some master …

Shameless self-plug - I built a "pastebin scraper as a service" platform, and released it here: https://github.com/shayanjm/pasteye Took much inspiration from dumpmon, but distribu…

I remember chatting with you a while back as I was also working on a pastebin scraping project. http://github.com/shayanjm/pasteye Glad to see dumpmon is still going strong :)

Absolutely - this wasn't meant to be a be-all-end-all to lead generation by geographical bounds. This was more of a "I had a cool idea, wanted to test it, and here's how I went abo…

@shayanjm on twitter. I have a half-baked contextual analysis implementation which I could probably spin into a high-volume twitter analysis tool. Was doing NLP analysis on unstruc…

Agreed. I think generating a more filtered list is possible - but would take significantly more time than it took to build the sentiment analysis tool. The results of the more-filt…
