- I work on a suite of open source public transit software projects, collectively called OneBusAway (or OBA). The software is used by millions of transit riders every day around the world, including in New York City, the Seattle area, San Diego, and Washington, D.C.
Since last month, our four Google Summer of Code interns finished their projects.
University of California San Diego has deployed our Wayfinder and Waystation web apps for their 35,000+ students!
We launched a redesign of our Android app.
Our next-generation server software, Maglev, is almost at v1.0!
We are always looking for more developers, biz dev, ux designers, product managers, and more to help out!
Open volunteer positions: https://ossvolunteers.com/organizations/open-transit-softwar...
Our software: https://github.com/OneBusAway/
More about us: https://opentransitsoftwarefoundation.org
- I just want to say thank you! I don't use it too often now that I don't live in the city, but I found OneBusAway invaluable ~10 years ago and I'm glad to hear it's still being developed actively. I don't have much free time at the moment, but I'll consider volunteering in the future.by psolidgold
- I’m working on translating the Renaissance — it was mostly written in Latin and 90% of it has never been translated to English. Even big names, like Ficino, Durer, Kircher, Fludd and Drebbel. And that’s Latin— things much more sparse in other classical languages.
https://SourceLibrary.org is a hub that now provides over 20,000 translations of classical texts in dozens of languages (Latin and Greek but also Chinese, Sanskrit, etc). We always provide the original image of the text next to the AI translation (so if you don’t trust it, you can do it again). For a sense of scale, SourceLibrary now hosts more words than English Wikipedia!
You can freely connect to the public MCP for research; that way AI can read books and not hallucinate quotes. In Claude, it also retrieves images directly into the chat.
This is a philanthropic project based at the non-profit “The Embassy of the Free Mind” in Amsterdam, a rare book library devoted to free thought and mysticism. https://embassyofthefreemind.com
SourceLibrary is totally free and open source. If we can raise the money, we hope to translate 100k books before the end of the year.
If you want to dive in, I’d suggest trying our research agent with a rabbithole topic of your choice: https://sourcelibrary.org/librarian/
by dr_dshiv - I am curious about this. I have found that there are number of primary works that have not been translated into english and are in the public domain in their native language. Translations are copyrighted if they are recent. I have a very short list of items which are of interest to me. They are things like Sundiata Lion King of Mali not having a public domain translation in English that I can find easily or there not being a public domain translation of Dede Korkut in English. Many of the better translations are copyrighted and not free.by NishanStepak
- It's a great endeavor. I put it at the bottom of my new search hub https://search.future-secured.com
I would just make sure all the titles can be clearly seen when superimposed over the pictures. Looks like a pressing matter to fix.
I actually liked the original https://archive.sacred-texts.com/ site because it's so fast and lightweight and classified by religions. I would also look at classification by languages. Is that being done at present?
I started a conversation about interfaces here if interested. https://share.gemini.google/ciOqbMFyCpBv
by adrianwaj - I run a small experiment on this: 29 paper-trading accounts on real US stock prices, $100k each, since July 27. Four AI models (ChatGPT, Claude, Grok, Gemini) each write a trading rulebook and rewrite it every day from their own results. One account is a fixed rulebook that no AI ever touches, as a control.
Result so far (paper, 34 trading days): the no-AI control is +13.0%, the S&P 500 is +3.4%, and 25 of the 28 AI accounts are below the control. The best single account is a Grok-written "patience" book at +40%, which I treat as one lucky account in a choppy market, not a finding. At the trade level the AIs and the control look the same: 3,212 closed positions, median +0.06%, median hold about 2 hours. They trade a lot and mostly go nowhere.
Everything is public, including the losses and the retired strategies: https://aitradingcompetition.com/which-ai-is-winning.html and the full trade file as CSV at https://github.com/ckamelhar-collab/ai-trading-arena-data. Paper money only, not advice, nothing for sale on those pages.

- Why didn't you let the bots backtest and forward test to pick the mix of best strategies/indicators?by bhairoxx
- The most likely outcome from a naive attempt to automate trading is random results.by wewewedxfgdf
- Don’t let AI write for you. Everyone can tell.by semiquaver
- None of this really means anything. For one if you test enough strategies one by luck will be killer. Second, past performance != future.
One AI might consist of some convulated strategy of who knows what, but all it takes in the end is for it to say...hold more tech stocks than not, or buying more call options or leveraged positions in a bull market, being more out of the market during a bearish market, etc. But that same strategy will fail miserably as soon as the market conditions change

- I'm building Orate, a free public speaking app:
• Users are given a prompt and have 2 minutes to answer.
• Speeches are reviewed by AI and other users.
Speaking eloquently "off the dome" is an incredibly useful skill, improving all your interactions with other people. And like a muscle, you can train it with dedicated practice until it becomes effortless.
It has been very fulfilling to listen to other people's speeches, knowing that we're helping each other pursue our shared goal of becoming excellent communicators.
If you're looking to improve your public speaking, I recommend you give it a try! https://apps.apple.com/il/app/orate-practice-speaking/id6761...
by jamesyun - Plans for android?
- You could “Pokémon Go” this and allow people to find performances they find interesting on a random street corner anywhere! Great idea!by andy_ppp
- Cool concept. Small feedback on the first user experience flow.
I downloaded the app to listen and write constructive notes for people, but I can’t enter the app until I’ve given microphone access and recorded a 30s clip. I’m on the bus, and can’t provide that audio now, and I’ll almost certainly forget about the app before I get 30 free seconds this evening. I think you’ll drop a lot of first time users here.
- You may find this interesting. "Orate" has a totally different meaning in Spanish. It basically means "Idiot" or "Demented". As in someone that has lost his/her mental abilities.
- https://curvefit.app
it's a weight-training app that helps you train along your "pareto frontier" of weight vs reps. The idea is to train at lower weight-higher rep, medium weight medium reps, and higher weight, lower reps for every movement. I tried to develop my own weight training program following bits and pieces of advice from bodybuilding forums and ended up injuring several tendons in my first year. So I did a bunch of research on tendon strengthening as well as what's most effective for hypertrophy (reps near failure) strength (reps near maximal load) and injury-prevention/frequency (not bringing yourself to failure too often) and designed an app to automatically prescribe and advance weights and reps based on your learned strength curve (Brzycki-like, with an added shape parameter)
The app is designed to make use of the free Cloudflare tier, so I can support thousands of athletes for just the cost of the domain name. I'm primarily interested in understanding the "Fatigue curve" - right now I have some basic per-set fatigue modeling (basically a log-linear strength dropoff) but I think it could be much better characterized with more data. I could go on and on about the modeling but my intention is to keep it free (maybe add some non-intrusive ads on content pages if it ever starts costing me a few pennies a month) but my primary interest is to be able to do statistical analysis on the data.

- > a bunch of research
What exactly is your "research"? Is it reading more bodybuilder forums (bro science) or is it physiological studies (actual science)?
by teiferer - Interesting, this reminds me of my workout planning tool, which I've been working on.by Akranazon
- Gave it a quick go as I'm looking to adopt some sort of fitness app. There's too much text/complexity for my taste.
The website could use some images/simplification to get going and then have more details and whatnot later on. It seems that you let the LLM generate the content itself (em dashes, emojis) - Personally I'd be skeptical of a fitness app that has most of its content LLM'izied.
On step 3 of the tutorial, it's not clear that you can scroll down and there's more there on a mac 16''. I was confused what to do. It didn't allow me to change to metric system either (which I later found in the user-settings). You can't 'esc' from the tutorial popup either.
by Bishonen88 - It looks interesting but as someone else noted, it needs more images and animations, way less walls of text.
There's a huge database of licensable animations that several apps I've seen use. E.g. take a look at the animations in Hevy. I forget the name of it now but you should be able to find it easily.
by esperent - Ok, presuming this is going to be a monetized thing aiming to compete in the market. (if not what follows should be ignored).
What about your app is better than what already exists from https://macrofactor.com/workouts/ , https://rpstrength.com/pages/hypertrophy-app , and maybe https://biolayne.com/workout-builder/ ?
All 3 incorporate some form of RIR progression, varying rep ranges, program builders, and (at least in RP) some form of feedback mechanism to tell how impactful the last training stimulus was on recovery.
Not trying to bash it, but to either 1.) help you think through your offer or 2) help you realize there's already a lot in the market.
If you're really just doing this for you, and your interests then glhf :)
by maerF0x0 - My wife and I continue to work on a private, paid, ad-free and personally customizable search engine: Uruky [1].
To signup you don't provide any information (a randomly-generated account number is assigned to you), and you can run a proof-of-work captcha to get 2h for free. You can choose among many different search providers (for defaults and per query), including Uruky Site Search, powering our own index.
Last month we reached 300 monthly active accounts and released an image search gallery mode, plus a simple calculator and conversion widget!
The main differences between Uruky and Kagi, DuckDuckGo, SearXNG, etc. are visible in the footer (right side), but one huge difference is that with Uruky, after being a paying customer for 12 months, you get copy of the source code (licensed as BUSL, into AGPLv3 in 2 years — a suggestion made here on HN)!
Our main challenge continues to be discoverability and outreach because we want to do it ethically (no Big Tech and no GenAI/LLMs). Ideas are welcome! We’ve been sponsoring open source projects, open source maintainers, and indie, small-web, and privacy-related websites and applications/groups/orgs. This month we're sponsoring NOYB [2]!
Feature-wise, for September the most visible things that shipped already were Tags and Scopes (top feature requests for a while). We’re also still (slowly and sustainably) increasing our own index, focused on indie/small web.
Thank you for reading this!
[NO-AI]: There is no generative AI product or service being offered, here.

- Been meaning to sign up to this after seeing it posted here before. Finally got around to it. First impressions are the amount of settings and options available are a little overwhelming if I wanted to suggest it to non-technical users. Have you considered / do you have any video tutorials on the different settings / getting the most out of Uruky?by RebelMonk
