I built an opinionated minimalist ePub/pdf online reader
Hey so I am making my own book reader and wanted to share it with y'all on hackernews and I saw a submission talking about DRM free books[0] so I decided to submit this submission on Hackernews to show what I am upto :-D I prefer minimalism so I have created three different flavors of it depending upon the particular use-cases and I have linked the most minimalist one as the submission. If someone is interested in a Epub/pdf reader, I have recently made one: https://epub.mirror.forum/ After making that, I was also feeling the need of having standard book downloads and…
What it does
In the maker’s words, at launch
Hey so I am making my own book reader and wanted to share it with y'all on hackernews and I saw a submission talking about DRM free books[0] so I decided to submit this submission on Hackernews to show what I am upto :-D I prefer minimalism so I have created three different flavors of it depending upon the particular use-cases and I have linked the most minimalist one as the submission. If someone is interested in a Epub/pdf reader, I have recently made one: https://epub.mirror.forum/ After making that, I was also feeling the need of having standard book downloads and seeing this project as well. I have added it first using cors.sh: https://guten.mirror.forum I have also added a cf worker native solution which focuses on the search aspect only as well: https://gutencf.mirror.forum Feel free to ask me or give me any feedback or which one you might like more within this somewhat A/B testing experiment of mine and I just hope that it might be useful to anybody. Cheers and take care! [0]: https://news.ycombinator.com/item?id=48709186

- LALurnby, a tool for better learning, is now open source2022 · github.com · ▲162
I've been working on Lurnby for 2 years. It's kind of like a mix of pocket + kindle + anki. It lets you => add add epubs, pdfs, and web articles to the app => highlight and add comments => tag and organize highlights => review them with a spaced repetition system Today I made the decision to open source the project. I'm passionate about helping other people learn to learn better and hope that this will allow a lot more innovation in the tool and the space. I'm very new to open source and development in general really, but looking forward to receiving the guidance of the community.

I love books! I had once come across a great list of book recommendations on the LessWrong website ("The Best Textbooks on Every Subject"). But when I had stumbled upon the list a couple of years ago the last comments and recommendations on it were from 2011. And similarly I found that most recommendations on the web suffer from this form of time decay. What I wanted was a site that had high quality recommendations similar to the LessWrong list that would feel fresh and current. Amazon was overwhelming for me since it has a gazillion books on each subject and the "Thanks! Arrived in good…

- AUA user powered copy editing tool (running on Ars Technica)2011 · ▲56
I blew off a bunch of "serious" side work last month and built a tiny little embeddable editing tool that I've wanted to have for Ars Technica since, well, the beginning of internet time. It lets any random user make edit suggestions for writers/editors to consider and act on. I think it's pretty cool and it's gotten some good use over the last few weeks. Of note, it's uses a single-field signup form. Edit administration is currently email based, so all it needs is an email address to get people going. I'm sure I'm not the only person to ever do this, but I basically just turned it on one…

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
