1. Show HN: Nutrient insights through your grocery receipts
URL: https://nutri.adrianstobbe.com/
Author: elchead
Description: Nutri is still in beta and the GPT-powered results are sometimes inaccurate. The nutrient information accuracy is good to get an overview, but there are still outliers at times. I'm looking to improve the accuracy through food databases. Furthermore, I'd like to add additional tips for combining / preparing food to improve its nutritional value. For example, iron absorption is improved through vitamin C, so combine chickpeas or leafy greens with lemon. Or combine beans with rice to get all amino acids.
On the UX side, I'd like to integrate a QR code on the desktop version to easily upload receipts through the phone. Furthermore, it would be great to have analytics over weeks on nutrient improvements over time. Nutri could also be a great accountability partner to track items high in sugar / processed foods.

2. Show HN: Pfuzz, a web fuzzer following the Unix philosophy
URL: https://github.com/codesoap/pfuzz
Author: codesoap
Description: I recently dipped my toes into bug bounty hunting and finding security flaws in web applications. As a friend of UNIX shells I was building a repertoire of command line tools to make and analyze HTTP requests. Fortunately there are already many suitable tools like curl, jq, different fuzzers and some really nice tools for specific tasks by Tom Hudson [1].
However, I disliked that the existing fuzzers were monoliths where I had no easy way of creating custom behavior or analyses. They commonly do a multitude of things: Create multiple requests using one or more wordlist, sending the request, possibly with rate limiting, displaying progress, applying filters to the received responses and storing the output. If you want something different from the offered features, for example custom delays between requests or a new filter for the responses, your only option is to dig into a moderately large code base and try to adapt it to your needs.
I am a fan of the UNIX philosophy and felt like it could help out here. If there was a common format for communicating HTTP requests and responses, an ecosystem of small, specialized tools could use it to work together and fulfill tasks like fuzzing, while allowing the user to easily create custom behavior by combining the existing tools in different ways or adding small, quick to write tools to the ecosystem.
This is what I've attempted with the httpipe format [2]. It is a line based JSON format for exchanging HTTP requests and responses. I have also built some first tools using this format, namely pfuzz [3] for creating HTTP requests from wordlists, preq [4] for sending HTTP requests and receiving their responses and hpstat [5] for filtering the responses by their HTTP status codes. Since it's a line based format, many UNIX tools can be used with it as well and since each line is JSON, jq can also be used for manipulation, filtering and displaying.

3. Show HN: OpenPledge – Make a career with Open Source contributions
URL: https://openpledge.io?source=hn2
Author: zigcBenx
Description: Hey!
As a full-stack developer involved in world of open source, I've often encountered valuable repositories with solutions to my problems, only to find them abandoned for years. Faced with the dilemma of contributing to such projects during work hours, I thought of a solution.
That's when the concept of OpenPledge was born — a web platform designed to address this very issue by allowing users (or corporations) to financially support specific open source issues. Imagine, no more abandoned projects, and developers passionate about contributing to open source can now do so more seamlessly and as a full time job.
OpenPledge has secured investment, and we're set to launch in February. Join us in shaping the future of open source sustainability.
Share your ideas, be an early adopter, and contribute to a thriving open source community. Visit https://openpledge.io?source=hn2 now!

5. Show HN: Finagg – free and nearly unlimited financial data
URL: https://github.com/theOGognf/finagg
Author: theOGognf
Description: finagg is a Python package and CLI that enables you to aggregate and update free financial data from a handful of high quality data sources all within your own SQL database.
Here're some quick facts about it:
- Implements nearly all of the BEA API, FRED API, and SEC EDGAR APIs (all of which have free and nearly unlimited data access)
- Only focused on macrodata (no intraday data support)
- Provides methods for transforming data from these APIs into normalized features that're readily useable for analysis, strategy development, and AI/ML
- The most popular methods include getting historical price earnings ratios, getting historical price earnings ratios normalized across industries, and sorting companies by their industry-normalized price earnings ratios
- Python >= 3.10 only (you should upgrade anyways if you haven't ;)
I'm looking for feedback on the overall package and CLI designs. Also, I'd appreciate any recommendations for implementing other financial data sources that're free with no daily API limits.
Cheers!

10. Show HN: Search on S3 Using AWS Lambda
URL: https://github.com/quickwit-oss/quickwit/tree/main/distribution/lambda
Author: rdettai
Description: Hi everyone,
During the last 3 months, I worked on the Quickwit search engine to adapt it for AWS Lambda runtime. I wrote a blog post to announce the beta release [0] and two tutorials to quickstart:
- Indexing and searching 20 million logs entries dataset [1].
- Implementing an E2E use case where an application generates data, uploads it in batches to S3. Users can then search through an HTTP API authenticated with an API Key [2].
On the performance side, I observed on a 20 million log dataset that search is sub-second, and analytics queries take from 1 to 4 second.
On the cost side, obviously the compute using Lambda is fairly expensive, but the huge win is that it scales to 0. Few other solutions do. For instance OpenSearch Serverless has a fixed cost around $700/months. On the search side, thanks to indexing, queries are usually way cheaper than scanning services like CloudWatch (at least 50x cheaper).
I would love to get the feedback from the community and see how I can push this further.

11. Show HN: OENT – A web app for creative writing with versatile flexibility
URL: https://oent.io/
Author: myalmeraikhi
Description: Hello everyone!
OENT is an app that came about from my constant struggles with creative writing in the available writing software.
Stories are sometimes told in a mixed-up order with flashbacks showing later events. A problem can be that these flashbacks might not have the correct continuity when put together.
The solution I came up with in OENT lets us view our story in two ways: "Story View" shows the story as it's told, and "Timeline View" shows the events in the order they actually happened.
On top of that, we have “events”, which are “story blocks” that form our documents. We can freely move them around in the same document or to other documents! They also can be reordered depending on their “Story Order” or “Timeline Order”
This feature is the foundation for other planned features. I'd like as many people as possible to try the app and give feedback on how it works and if there are any problems that need fixing!

Author: jovanovski
Description: I followed up on Devon's original idea (https://news.ycombinator.com/item?id=38457815) with a redesigned one that works with both prompts and images + prompts, and reads the responses back to you in the glasses.
A bit of annoying to set up the whole reading back to you part, but totally doable.
Pros:
- Done via a browser extension
- No need for a server
- No need for fake FB accounts, official way to make one
Cons:
- Reading back involves quite a setup with FB apps & pages

URL: https://ixlabs.app
Author: nmfisher
Description: Hi all - I wanted to showcase the current state of AI text-to-motion models, so I put together this small demo app [0]. It uses the MoMask[1] model on the backend (I'm not affiliated with that team, just a fan of their work). They have a visualization on their HF space[2] but I thought it would be better to see the generated animations with an actual model.
I'd really like to take this further and create a platform for generating high-quality/professional-grade animations. That requires a clean/curated dataset, which I won't be able to fund on my own. If this is something you're interested in using, it would be very helpful if you could register your interest @ https://tally.so/r/mJzRJo
[0] Web support for the front-end renderer is still experimental so please let me know if you experience any issues. In particular, iOS Safari won't work so I've disabled that completely.

23. Show HN: Puffin – an open-source NLP-powered Discord bot
URL: https://github.com/Windshield-Viper/Puffin-Discord-Bot
Author: squiddlyg
Description: I'm not a super experienced programmer or a deep learning wizard, but I've been wanting to make something like this for a long time. Puffin is a Discord bot that uses NLP and zero-shot learning as well as Google's Toxicity API to flag unsavory messages in servers. Each message is analyzed for sentiment, emotion, and custom zero-shot labels that moderators can provide. If scores for certain emotions are too high, the labels are true, or the message seems to be very toxic, the message is added to a moderation queue hosted in MongoDB. Moderators can view and delete this queue at their will, while not having the bot actually delete anything that shouldn't be deleted. The bot is currently hosted on a Raspberry Pi 5, is written in discord.py, and uses the Hugging Face pipeline.
In general, from what I've seen, most auto-moderation solutions that use NLP are either paywalled or non-transparent, and I'm hoping to change that a little bit with this bot. Are there any things that I should change? Are there any features that I should add?

URL: https://github.com/joeycumines/go-smartpoll
Author: joeycumines
Description: Hey HN,
I'm sharing github.com/joeycumines/go-smartpoll, a package I've been working on that offers dynamic, reactive scheduling for (among other things) polling of multiple data points, and aggregating the results. It's designed to make it easy to implement a control loop, which involves scheduling "tasks", which run independently, in a singleflight-like manner.
I've consolidated the implementation from a pattern I've been using to implement streaming API methods to wrangle non-atomic, potentially slow/cached external APIs, into a consistent stream of updates, which includes changes made that haven't been reflected in the actual data source, yet. There are many ways to use it though - there's a litmus test in the readme.
I've made an effort to write useful documentation, but it has only gone through one pass.
Tell me what you think, especially re: documentation :)
