3. Show HN: BSON Extension for SQLite
URL: https://github.com/buzzm/sqlitebson
Author: buzzm
Description: sqlite is, well, everywhere. It's a little shy on high-fidelity types, though, esp no dates and penny-precise numbers. And carrying rich shapes in JSON doesn't really help because JSON lacks those too. BSON supports these types but more importantly is a data carrier external to the database; you can fluidly move BSON in and out of sqlite without creating your own binary representations; just use the BSON SDK for your environment. Upwards of 20 languages are supported. The BSON extension is designed to exploit sqlite built-in JSON functions as desired.

6. Show HN: AI quizzes for your content – organised in memorable emoji lessons
URL: https://www.revision.ai?hn2024
Author: james-revisoai
Description: This learning tool turns learning content* into an organised, curriculum-like quiz experience. It makes sensible lessons, containing quiz questions and motivating you with progress! You can usually see all lessons at a glance on one page[https://revision.ai/images/splash/lessons.png].
* a PDF (like a lecture slideshow), PPTX, Wiki page, or a Youtube video
- Each lesson has a topic-based emoji ()and shows a proportionate visual pie chart for your progress
- There is a single "unlocking" path, with 2 teaser lessons, which always gives you one simple "Next Step"
- And by viewing the overview, you can view a wall of Golded lessons to tell when you are nailing the recall-level understanding on the content.
The content/quiz questions are inspired by Active Recall (Roediger & Karpicke, 2006) and the Minimum Information Principle from Anki. And it's freemium with 2 free runs :) You can also highlight your PDFs for studying.
I built the lessons aspect with care, taking lessons from what hadn't worked before: a) using something visually and uniquely memorable for you - a unique emoji chosen by AI for each lesson! b) doing question generation -after- choosing sensible lessons, so questions are tailored to the PDF-specific lessons... c) making it a "one-way learning path" was to make learning easier: previous semantic(vector DB-like) maps of concepts/trees were unencouragingly overengineered!
Fun fact on the name - "Revision" means "to study for an exam" in a lot of places, like the UK... less Stalinist, you see.
I have future plans ofcourse! Now I'd love feedback and thoughts - so do get me started on preprocessing or the psychology of learning... Let me know your thoughts.

8. Show HN: npx tmole <port> – No-Install Public URL for Locally Running Services
URL: #
Author: aussieguy1234
Description: I'm excited to introduce a quick and easy way to provide public access to your locally running services: npx tmole <port>. It utilizes Tunnelmole (1), an open-source tunneling tool, without any need to explicitly install anything.
Here's how it works: npx tmole <port> sets up a tunnel via the service at tunnelmole.com. The Public URL provided in the output will then direct to your locally running web service.
Getting started is as simple as running npx tmole <port>. For instance, if your service is running on port 3000, use npx tmole 3000.
You'll need to have NodeJS for this to work.
Please give it a try and share your experience. I'd love to hear your feedback on the tool and any suggestions you may have.

12. Show HN: A Python PDF Form Library
URL: https://github.com/chinapandaman/PyPDFForm
Author: chinapandaman
Description: Hi HN! I have a project that I have been working on for three years that I’d love to show you today called PyPDForm (https://github.com/chinapandaman/PyPDFForm). It is a Python library that specializes in processing PDF forms, with the most outstanding feature being programmatically filling a PDF form by simply feeding a Python dictionary.
I used to work at a startup company with Python as our backend stack. We were constantly given paper documents by our clients that we needed to generate into PDFs. We were doing it using reportlab scripts and I quickly found the process tedious and time consuming for more complex PDFs.
This is where the idea of this project came from. Instead of writing lengthy and unmaintainable reportlab scripts to generate PDFs, you can just turn any paper document into a PDF form template and PyPDFForm can fill it easily.
On top of the GitHub repo, here are some additional resources for this project:
PyPi: https://pypi.org/project/PyPDFForm/
Docs: https://chinapandaman.github.io/PyPDFForm/
A public speak I did about this project: https://www.youtube.com/watch?v=8t1RdAKwr9w
I hope you guys find the library helpful for your own PDF generation workflow. Feel free to try it, test it, leave comments or suggestions, and open issues. And of course if you are willing, kindly give me a star on GitHub.

14. Show HN: Hacker News Userscript Written in Rust WASM – Filtering and Hiding
URL: https://github.com/drakerossman/hackernews-userscript
Author: drakerossman
Description: Hi everyone,
I present you the Hackernews Userscript - a userscript written in Rust Wasm that provides functionality to filter stuff based on keywords, as well as implements soft-hide: HN's default "hide" button behavior stores hidden items server-side, plus it pulls the items to the front page from the next one, so the page is always full with 30 items. Userscript's "hide" hides the stuff locally, and it does not pull anything, so you can hide the entire page to save your valuable attention. You can also use this function to mark the already-read articles.
I've had this idea to implement such a script since quite a while ago, in fact, back when Wordle was all the hype. Now we got some other hypes, and all of that is filterable - via a textmatch, or via regex.
The script is written in Rust, since I wanted to checkout the wasm bindgen functionality, and also for the peace of mind did not want to use JS.
It is published at both Firefox and Chrome web stores:
- https://addons.mozilla.org/en-US/firefox/addon/hackernews-us...
- https://chromewebstore.google.com/detail/hackernews-userscri...
I've also posted the extension page to my blog: https://drakerossman.com/blog/hackernews-userscript-in-rust-...
Looking forward for to implement more features, stuff like favorites, autoupdate, etc., and currently refactoring the codebase.
Your feedback is very welcome!

24. Show HN: A programmatic partition editor in Perl
URL: https://github.com/csdvrx/hdisk
Author: csdvrx
Description: First, I wanted to check how bootable media was made, so I started by writing something to read the MBR and check for El Torito records: that's mbr-read.pl
Then I wanted to look at the GPT, so I did the same for the GPT: that's gpt-read.pl
I merged them both in hdisk-read.pl and I started looking at ISOs to see why they were booting and how.
Then I decided I wanted to programmatically write hybrid MBR in a way that's easier than gdisk and that offers more control that xorriso - that's hdisk-tweak.
The goal is to use IFFT logic based on existing GPT or MBR partitions to write an hybrid matching your exact specifications: instead of a protective 0xEE MBR partition, you have actual MBR partitions matching the GPT partitions

25. Show HN: Summarywithai.com – Useful, formatted summaries for long PDFs
URL: https://www.summarywithai.com/
Author: soumyag
Description: Hey HN!
I tried a number of AI document summary tools and encountered a few issues
- summaries fail to capture all the core ideas in a document
- limits on file uploads - 5MB, 25MB and so on
- chatbots repeat the text from the "conclusions" or "executive summary" sections of the document without actually extracting information from the entire document
- for longer documents, more information is included from the beginning of the document, later pages get ignored completely
Summary With AI is the tool I'm using to read reports and research papers faster. It creates a comprehensive summary extracting information from all pages of a document.
- Can handle uploads of 200 MB
- Tested on documents upto 200 pages
- Summary PDF contains 1-2 page overview followed by a more detailed summary
Demo: https://youtube.com/shorts/ffqwjDAaogM?feature=share
Examples: Research Papers: https://www.summarywithai.com/blog/read-research-papers-fast... Climate Reports: https://www.summarywithai.com/blog/summarize-climate-reports Corporate Annual Reports: https://www.summarywithai.com/blog/read-corporate-annual-rep...

27. Show HN: Experimenting with generating SVG diagrams and visualizations
URL: https://slidemagic.framer.ai/
Author: grbsh
Description: I ran a quick experiment to see if I could generate SVGs using an LLM with good layout. This is an interesting task, because it requires spatial reasoning and planning (it can easily start off well-laid out, but run out of space as you can see in some of the examples in the linked framer site).
I started with a single prompt to GPT4. The results were pretty terrible in terms of layout (many overlapping / obstructed elements), but (I think) show promise. Also, it takes a really long time to generate, because the SVG path is usually 1-2 characters per token.
Next, I implemented a visual critique and self-refinement. I created a rubric that asked a bunch of questions about layout and educational / communicative value. I take the initial generated SVG, convert it to PNG and send it to gpt-4-vision-preview with the rubric, asking for a critique and regeneration.
The generation + visual self-critique and refinement takes about 3 minutes per SVG, so I generated about 300 examples, eliminated the bottom 50%, and fine-tuned on gpt-3.5-turbo. The fine-tune now takes about 7-10 seconds to generate one SVG with comparable quality to the GPT4 + GPT4-V refinement pipeline (according to GPT4-V's own scoring of the rubric).
Thoughts on this approach? I'm considering doing 10-100x the compute / dataset size, wondering if this interests anyone else. Happy to expose a (free) API to the fine-tuned model if people are interested in playing around with it.

URL: https://gist.github.com/dossy/28d31aa155632a3ffeaaa95adc4ecfe2
Author: dossy
Description: Back on 2023-09-03, W-Stool asked about printing source code, and I said I do it using GNU enscript, but never followed up with the actual command. (See: https://news.ycombinator.com/item?id=37366968)
Tonight, I wrote up the command in a little GitHub Gist.
Not sure if this will be helpful to anyone else, but maybe this will save someone some trial and error.
