1. Show HN: Htmldocs – Typeset and generate pdfs with HTML/CSS
URL: https://htmldocs.com
Author: kelvinzhang
Description: htmldocs is an Overleaf-style editor for typesetting documents using HTML/CSS, which provides the same benefits as LaTeX while being more accessible, customizable, and familiar.
I built this because I wanted to programatically generate invoices as well as automatically tailor my resume to jobs but had no good way of generating well-formatted PDFs. I ended up building a templating engine to Chromium rendering pipeline to generate PDFs, and due to the amount of engineering effort, turned it into a tool for others that might want to do the same. There's a built-in API (https://htmldocs.com/docs/documents) that you can call to turn JSON into PDFs in a single call.
htmldocs is different from other tools like Wkhtmltopdf and Weasyprint in that it uses Chromium to generate PDFs, meaning that it supports the most modern CSS features and there's minimal drift between the rendered HTML document and PDF.
Will also consider open sourcing if there's enough interest in the project!

URL: https://www.factsmachine.ai/p/marvins-turning-20
Author: jlowin
Description: Hey HN! We just released Marvin 2.0.
Marvin is an AI toolkit for developers who want to use LLMs with traditional software. We still see significant challenges integrating LLMs because of how difficult it is to get them to reliably accept and return structured data. Marvin consists of independent, functional tools that address this problem in a variety of ways.
Marvin has always been focused on using LLMs to work with native Python datatypes and Pydantic models. In 2.0 we've expanded this significantly with dedicated APIs for the most common use cases we've seen over the last year: classification, entity extraction, transforming data to types, and generating synthetic data. Marvin 2.0 is also fully multi-modal and supports images as inputs for classification, extraction, and transformation tasks (as well as simple image and speech generation). We've also introduces a Pythonic interface to OpenAI's assistants API, which now powers all of Marvin's interactive components.
We've tried to make an LLM framework that "sparks joy" and captures that same feeling you had the first time you saw an LLM in action. Try it out and let us know what you think!

URL: https://transitiverobotics.com/blog/self-hosting/
Author: chfritz
Description: After three years in development, I'm thrilled to share Transitive: an open-source framework for full-stack robotic software (https://github.com/transitiverobotics/transitive).
The Transitive framework makes it easy to build robot cloud portals. Even given all the great open-source tools for web development and device management, building such cloud portals for robots is still not an easy task. There are several reasons for this, but a big one is that robots are different from regular servers, despite many people attempting to tread them as such. They go offline a lot, have limited network bandwidth, and each robot in a fleet may run a different version of software and require a different configuration. Robots also generate a lot of data, some of which needs to be synced in real-time with cloud and web front-ends for processing and visualization, some of which recorded, and some discarded. In addition robots roam insecure areas and are connected over networks outside of the control of the startup, hence requiring tight authentication and authorization.
Transitive solves many of these issues. It provides a reliable, real-time data synchronization protocol that operates on top of MQTT, called MQTTSync. MQTTSync seamlessly synchronizes stateful data between robot, cloud, and web, instead of just passing messages. It provides the notion of full-stack packages that implement encapsulation and versioning of software components for all three systems (robot, cloud, and web) and uses MQTTSync's name-spaced data model to reliably communicate and operate, even when different robots run different versions of the package. The robot and cloud components are run in sandboxes to isolate them from the rest of the system, and the web components can be embedded in any web page including existing robot cloud portals. And of course, all this is secured, using SSL for transport-level security, client certificates and JSON Web Tokens for authentication, and authorization based on MQTT topics. Taken together this lays a solid foundation for building new full-stack capabilities with ease.
Note that Transitive is not a replacement for ROS, and in fact many of our capabilities run ROS nodes on the robot. Neither is Transitive a fleet management system. It just makes it easy for you to build your own!

If you just want to try it out quickly please go to https://portal.transitiverobotics.com/register to create a free account, which will also give you some starting credit for try out any of our premium capabilities, such as webrtc-based video streaming, our web-terminal, or file-sync ("Dropbox for robots").

16. Show HN: Coverage Critic Map – Combined Coverage Map for US Cell Networks
URL: https://coveragecritic.com/map/
Author: chris-smith
Description: Hi HN!
I built a map that shows cell coverage from the major US networks. It draws primarily on data from the FCC, but that's supplemented/calibrated with a bunch of crowdsourced data from the DIMO project (dimo.zone).
My goal is to make comparisons between networks super easy--one click to toggle between networks or technologies.
I'm never sure how much to trust networks' self-published maps. I'm still in the early days of incorporating the crowdsourced data, but I'm hoping all the on-the-ground data can lead to a map that's more reliable than network operators' maps (those are largely based on RF modeling).
Couple notes: -Toggle options from the settings menu, like adding Dish & US Cellular or switching to exclusively crowdsourced data -Map shows native (non-roaming) coverage -Coverage info is most detailed while zoomed in
Would love any feedback!
Cheers, Chris

Author: hoothin
Description: I enjoy collecting various search engines, but some of them lack support for GET/POST searches and switching between different search engines can be a hassle. So, I developed this browser extension that enables automated searching on websites that don't support GET/POST through simulated input and clicks. It also offers one-click switching between search engines. Additionally, it highlights the searched keywords on the search results page. Lastly, it allows cross-domain data fetching and displays the information in a pop-up layer within the current page.

Author: haroonchoudery
Description: Hey HN!
Today we're launching Building with AI, a one-stop-shop to learn how to build AI products that wow
We’ve spent thousands of hours with AI product leaders and experts from companies like OpenAI, Fireflies, and Gamma to deconstruct the tactics & best practices included in these resources.
The backstory
In 2017, my brother and I launched A.I. For Anyone—a nonprofit that taught AI fundamentals to over 70,000 people. Today, we’re co-founders of Autoblocks, a solution for testing and improving GenAI products.
We realized two important things during this journey:
1/ The best product teams follow a set of best practices when building with AI, and
2/ Educational resources for AI product builders aren’t very good.
What’s up ahead
Season 2 of BWAI Podcast: Our flagship podcast is back for another season, letting you hear directly from top AI product builders and experts.
BWAI Newsletter: Fresh insights delivered straight to your inbox! In each issue, we dig into a key idea at the intersection of AI and product building.
BWAI Academy: Tactical guides that dig deeper into best practices from top AI product builders.
Did we mention all of this is free? Excited to hear what you all think!

26. Show HN: Dygres – The privacy focused social media without ads and algorithms
Author: drpiratecaptain
Description: Hey Hacker News, excited to reveal the alpha for dygres! The no nonsense, 100% free to use social media aimed at protecting your data and elevating the way we see online communication.
Having been a social media user since the myspace days, I had become disillusioned with how far social media has strayed away from communicating and how much it has gravitated towards advertising, pushing agendas, misinformation and silencing critics.
My goal with dygres is to build a social media that operates on its own global independent network, where users are in total control of their data, the content they see and are compensated for the content they create among many other yet to be revealed features.
Some of the planned features for dygres:
Designed with distributed governance in mind so that the userbase plays an active role in the platforms evolution and management.
With no algorithms in play, the userbase effectively decides what rises to the top and what fades into obscurity. This makes trending content a natural response to the collectives emotions, likes and dislikes. This also ensures that true creativity and originality is now rewarded rather than obscured in favor of likeness based on an algorithmic evaluation of what's trending or consumed.
A tiered verification system ensures any content you see weeds out bad actors and fake accounts. Built in checks that trigger at certain account milestones ensure that the verification isn't a one and done deal.
A natural lifecycle for every post to prevent any horse beating.
No advertisers means we do not collect or sell your data to any third parties. In fact you can delete your account at any time which erases your existence from the platform. The ad free nature of the platform helps maintain a focus on user generated content freeing you from distractions and a need to be constantly reminded to buy something.
To celebrate the launch of this alpha, I have added a small feature that is in a very early stage. Internally its called "yggdrasil". Every user gets a sign up link that they can share and successful sign ups add to a tree. Overtime this feature will develop and sign ups will form a picture of of the online user base. Hopefully it works at scale .
My link to sign up to dygres: https://dygres.com/share/drpiratecaptain
The journey for dygres is a long one but this alpha has been a long time in the making and rather than seek perfection, I am moving to seek as much feedback as possible at this early stage so that future development is guided by user input rather than the beliefs and opinions of a small group of people.
On a final note, I just want to say that I know the platform is very bare bones and lacks a lot of the features that the biggest platforms have at the moment. This however is a completely bootstrapped platform built with the dev support of a very small team so please forgive the very spartan nature of the build. A roadmap exists to evolve the platform further and introduce features that will take the user experience to the next level.
Thank you for taking the time to read my post and checking out dygres.

Description: Ciao HN! We made Paparazzi Docs, a dev tool that updates documentation screenshots in seconds instead of hours. We love to ship code fast. But… Documentation and guide maintenance are slow and a pain for us.
Paparazzi Docs will take a screenshot of each page whenever you run your tests and automagically update your docs with the new ones.
- Integrate our npm package into your E2E tests, like Cypress.
- Craft and revise your documents and guides with our editor, which converts what you write into MDX format.
- Deploy a Nextra template with all your changes with one click.
We’re a team of just two developers. We chose to develop Paparazzi Docs because we saw firsthand that updating docs slows down the release of new features.

Author: nikhelical
Description: Hello All,
We are working on and about to launch in Beta a data engineering tool which is completely chat based.
Looking for some help in getting beta customers for early feedback.
MAIN USP
- Chat interface: Very simple to use
- No learning curve
- No technical knowledge required to use, simply type what you want in plain English language
- Very fast speed of development, data engineering at the speed of typing
Simply chat, see in preview how your chat is affecting the data and then finally schedule.
This can be used by data scientists who are looking to process or clean data before they run their ML AI algos. It can be used by BI Enggs who often need to create calculated tables columns for their further BI analysis. It can also be used by Data Enggs as it can really speed up their entire data pipelines creation work exponentially.
Right now we are supporting only structured data but later we would add support of unstructured data also. Also in future not only data engineering but even data science work also you would be able to do.
Please reach out on support@askondata.com with any questions, suggestions or feedback.
Thankyou to this lovely community

42. Show HN: PicKey – Managing Passwords with AI, Visually
URL: https://pickey.ai
Author: garyiskidding
Description: Hello HN,
With about 24% of internet users using passwords like "password123" and "123456", we wanted to create a visually-based alternative without compromising on security.
Humans remember visuals much better than text, and so we've created a password manager that uses a combination of a personal image and a 3D character (superimposed on the image) as the master password that one can see with their own eyes, making it visually recallable with a much lower cognitive load while making it stronger than text-based passwords.
We call this visual master password as the Master Key. It is made of 2 parts:
Part 1 - a picture of a favorite place, a cherished object, or a face (Vision Secret): PicKey uses general adaptive recognition backed by multiple neural networks that are trained to recognize places, faces, objects, etc., adapting to physical changes (view angle, lighting, seasons, age, etc.). To a user, this means that they could turn their living room into a master password, or their pet, or their favorite spot in the park, or that painting on the wall. The possibilities are endless. The Vision Secret captures high entropy from the personal nature of choices that people make and anonymizes the secret.
Part 2 - a 3D character (Keymoji Secret): A virtual, 3D character can then be selected from a growing catalogue. This has lower entropy, but the main focus here is to engage our remembrance. The 3D character is often animated and has music/sound and can be viewed in 3D or in Augmented Reality. Continuing with the examples above, a user could have a roaring t-rex in their living room, or a butterfly flapping over their pet, or an alien at that spot in the park, or a hummingbird hovering in front of their paining on the wall.
This combination forms the Master Key and is used to login to PicKey. PicKey then works like any password manager, capturing, autofilling & managing passwords & more; across platforms.
Safety:
- E2E encryption as default, AES-256/GCM/CBC, multi-hashing, salting, time gaps, ZKP, KDF, 2FA, OAuth2
- Cryptographically secure key, IV and ID generation
- MagicPass - storage free passwords that are never stored anywhere; regenerated at runtime from the vision vector and a specialized hash function.
Misc:
- Master keys are anonymous; even a public social media post can serve as the master password. Anything memorable visually can become a master key, aiming to mimic adaptive human photographic memory and its uniqueness.
- the master key login is generally long lived and manages the session based on frequency of use.
- we recommend live retaking of the 'Vision Secret' at login, enhancing security. For ease, users can choose easily accessible or memorable live images, a familiar online image, or their cherished object/place, or even their face (not recommended for anonymity); ensuring consistent and secure access.
- a picture based password gains resistance to traditional attacks on regular passwords like dictionary attacks, rainbow tables, keylogging etc, though the neural networks have to be hardened for new types on attacks on them.
- PicKey neither collects, nor stores any personally identifiable info.
