i'm this old: i don't think you should name packages in SWE with names that you will eventually cave in and change if the project gets real use.

"The Context-Minimization pattern"

You can copy the injection into the text of the query. SELECT "ignore all previous instructions" FROM ...

Might need to escape it in a wya that the LLM will pick up on like "---" for new section.

I'm building a game with a similar idea. encounters are controlled by the AI. there is a classic RPG system built around it and human generated content for the world and story.

while it is true that there is a gap between what most LLMs "know" and current time that gap is getting smaller not larger with time, it is also possible to teach a model pass the knowledge cut-off with tools and an LLM might be encouraged to be aware of the gap and reach out for the latest information when it might have changed (pi is still pi but the country with the most people might have changed)

Is the radiation not similar to the one you get in space? seems like that would be a cheaper place to test the effects of radiation.

support for typescript as long as you are only using it for type checking, not if you are also using features that are not supported in the javascript version you are targeting.

Show HN: Language Learning App

ofirg — Thu, 09 May 2024 07:40:47 +0000

Backstory: my partner and I developed a language learning app that had some good traction around 2016, but we couldn’t raise enough money to build it out and market it further as much as we’d have liked, and since 2020 it’s largely been in hibernation. We’re talking about diving back in and fundraising again, but are concerned the market has passed us by and, product wise, things may be too stacked against us, even if we raise money. We have some unique approaches: - In our main course, we data mine TV transcripts to teach people vocabulary in order of how likely they’ll be to encounter it. - We built algorithms to track how well a user knows each meaning of a word. This allows us to prioritize teaching sentences that have the most words/grammatical concepts each specific user needs to practice, and it lets us teach through personalized spaced repetition. - We let users learn from special topics and songs whenever they want. They can help bridge their personal vocabulary with the vocab of the course/song. For example, if you already know 50% of the words in a song that you’re interested in, we’ll teach you the 50% you don’t know so that you can understand all of it. My real question is: is our actual user experience uniquely positive enough to differentiate us? We built the app (Language Zen) to go up against Rosetta Stone, early Duolingo, Babbel and Busuu. Since then, Duolingo has advanced a lot, and there are new, interesting apps like Speak, Mondly, Lingvist and Falou.

If we decide to stick with it and successfully raise money, our main focuses will be: - Building out additional languages (we currently just have Spanish) - Gamifying the experience - Building more exercises and material to help users with grammar and other challenges (while showing off our adaptability algorithms more)

If you have experience with our competitors, I’d be super grateful you give our app a try and let me know your thoughts on if what we have is special/worthwhile. If you hit a paywall, send me with your email and I’ll give you free premium (micah@languagezen.com). Any thoughts on the product or company would be sincerely appreciated.

I support closing the offices and making them persona non grata, but blocking the site is wrong and silly, makes us look like we are afraid of words.

"but based on the thousands of companies YC has funded over the years, companies lacking a technical co-founder underperform"

which could mean soon-to-be-underperforming companies fail to attract technical co-founders

Blackmail is often restricted to publishing information regarding an illegel activity, not just an embarrassing one, in which case the public is the victim of both the potential coverup and the discriminatory enforcement of the law.
