Built an open-source Nepali calendar API that computes dates astronomically

Been working on this for a couple months. It's called Project Parva, basically an API that computes Nepali calendar stuff (BS/AD conversion, festival dates, panchanga, muhurta) using real planetary position data from Swiss Ephemeris rather than storing hardcoded dates someone typed in from a government PDF.

The main thing that bothered me about existing stuff is they all assume Kathmandu. If you're building something for diaspora users, the sunrise-dependent calculations (tithi, muhurta windows) are just wrong for anyone outside KTM. This one takes actual lat/lon.

Verified against 65 dates from MoHA holiday PDFs across 2080-2082, passes all of them.

Here's my project,
GitHub: https://github.com/dantwoashim/Project_Parva

reddit seems to flag the direct link to the API

 (AGPL, open source)
Happy to answer questions or take feedback on what's missing.

Building an open source tool to make working with AI agents truly useful — looking for feedback

Building an open source tool to make working with AI agents truly useful — looking for feedback

I've been working on an idea for the last month — what if we treat AI agents like real co-workers? You talk to them, they talk to each other, and everyone shares a drive to exchange files. Like a real office, but with agents.

I built the first version and it's been working surprisingly well. I have a team dedicated to building and maintaining a website: product manager, frontend dev, designer, and SEO specialist. They maintain the code, design, and SEO. If I want a straightforward change, I talk to the frontend dev. If I want a whole new feature, I talk to the product manager and he coordinates with the rest of the team to build and ship it. They have all the context from previous sessions — no starting from scratch every time.

I set it up for my wife and she built a team of agents to manage her trading — screener, back-tester, analyst. Now she can't stop playing with it.

That's why I decided to open source it — Shire. I want to see if others find this as useful as we do.

With Shire:

  • You build a dedicated agent team for each project — they're long-lived and have their own filesystem
  • Agents communicate with each other directly. No orchestrator, no fixed workflow — collaboration happens naturally
  • You can schedule tasks so agents run on autopilot
  • Run it locally or on any machine
  • Works with Claude Code, Pi Agent, and OpenCode — so you can bring your preferred model

npm install -g agents-shire — single command install.

Any feedback, comments, and stars welcome:

Free ai ofm guide

Hey everyone,

I just made a free beginner guide for AI OFM that covers how to actually get started from scratch. I noticed a lot of people are confused at the beginning, so I tried to simplify things and make it practical.

This guide should help you understand the basics and take your first steps without overcomplicating it.

I’ll be posting more guides soon going deeper into strategy, growth, and scaling.

If you get stuck or need help, feel free to let me know I’ll try to help where I can.

Also, we’re opening a Discord community, and the first 20 people can join for free where we go more in depth and help each other out.

Appreciate any feedback 🙌

We spent a year helping B2B SaaS companies use YouTube for acquisition. Here's the one mistake every single one made.
▲ 6 r/SaaS+2 crossposts

We spent a year helping B2B SaaS companies use YouTube for acquisition. Here's the one mistake every single one made.

Over the last year I've worked with SaaS companies trying to use YouTube as a customer acquisition channel. Not brand content, not "thought leadership", actual pipeline generation from YouTube search.

Every single one made the same mistake before they came to us. And it's the same mistake I see repeated in every "how to grow on YouTube" guide written for businesses.

The mistake: they picked video topics the way they pick blog topics.

They'd find high-volume keywords in their space, make videos on those topics, and expect the same content-to-lead pipeline they get from SEO blog posts.

It doesn't work because YouTube search behavior is fundamentally different from Google search behavior.

  • On Google, someone searching "best project management software" is often in evaluation mode, they'll read 3 comparison articles and maybe sign up for a trial. 
  • On YouTube, that same query surfaces a mix of tutorial content, creator reviews, and entertainment. The person watching might be evaluating, or they might just be killing time watching software reviews for fun.

The queries that actually convert on YouTube are more specific and more action-oriented:

  • "How to set up [competitor] for [specific workflow]" → they're implementing something and might switch if yours is easier
  • "[Your category] for [specific use case]" → they're searching for a solution to a defined problem
  • "[Competitor A] vs [Competitor B] for [job to be done]" → they're in active comparison mode
  • These get 1/10th the search volume of the broad queries. But the people watching are 10x more likely to have a problem your product actually solves.

The shift that changes everything:

  • Stop optimizing for YouTube volume. 
  • Start optimizing for buyer intent behind the query.

So what did we do? We built some free tools around this because we got tired of explaining it on calls:

  • One that scores your existing videos on buyer intent (not just "SEO")
  • One that generates video ideas starting from your product and ideal customer, not from search volume
  • One that tells you if a video idea will attract buyers or viewers before you produce it

They're at sellontube.com/tools if anyone wants to try them.
No signup, no email gate.

The bigger point: if you're a SaaS company where a single customer is worth $1k+ annually, YouTube search is probably the highest-leverage acquisition channel you're not using. But only if you target the right queries.

Happy to go deeper on any of this, especially around how to find buyer-intent queries in specific SaaS verticals.

Hi guys I built this website to generate job matching resumes in seconds

Hey guys!

As you may know, the job market is super competitive right now. The number of applications for a job could be 1 over hundreds or thousands of people. If you guys want to land your dream role, you have to spend hours searching for jobs, preparing your applications, and applying to as many as you can. This does not even include time you spend leveling up yourself, learning something new, or building projects.

The learning path is mandatory; you can't take the shortcut. I understand.

However, you can save hours a day looking for jobs, updating resumes, and applying to them. If that sounds like you, then check out this new product I just built.

The idea behind my product is simple. When I apply for jobs, I normally read the job description, tailor my resume to match it, write a cover letter, then submit all of them with my info details. The process seems to be fast, but when it comes to 10 to 20 applications per day (or even more), I just can't do it.

That's when I knew I had to build something to remove the manual work completely for me.

And Resumie was born!

Resumie is built for SWE. It helps generate multiple job-matching resumes in seconds. Just need to copy paste the job description, input personal data, add GitHub repos and LinkedIn, then Resumie does the rest.

Resumie scans everything to build a new tailored resume for each job:

  • ATS friendly
  • Harvard style
  • Include your best projects, what you did, what has been achieved, etc.
  • Professional working experience, focusing on XYZ template (Accomplished [X] as measured by [Y], by doing [Z])
  • Technical skills match job description

Resumie is built to speed up the application process while maintaining the best possible resume output, instead of bringing only a single resume for all job positions.

Feel free to give it a try and return here with some feedback. It's FREE and I just keep a limit on the number of resume generations.

Here's the link for you to try: Resumie

That site saved my projects and time

Hey everyone,

I've been building side projects with Cursor and Claude Code for a while, and kept running into the same issue: AI agents drift when they don't have a structured spec to anchor against.

So I built MDCreator — it interviews you about your idea and generates a full technical blueprint:

- Product Requirements Document

- Tech stack recommendations

- Database schema

- API endpoint list

- 3-phase implementation plan

Takes about 8 minutes. You describe your idea (rough is fine), the AI asks 3-5 questions, and you get a ZIP with all the spec files you can paste into Cursor context.

Free tier includes 1 complete spec. Pro is $12/month for unlimited.

Would love feedback from this community — especially if you're doing any vibe coding or AI-assisted development.

I built a game where you have to answer trivia questions to control the snake — multiplayer too

Hey everyone,

I've been building a learning game for the past few months and finally feel ready to share it.

The concept: it's Snake, but every time you eat food, you get a trivia question. Answer wrong = you lose control of the snake. There's also

multiplayer, a leaderboard, power-ups, and daily challenges.

I built it because I hate studying but I love games — figured I'm probably not alone.

Would love brutal honest feedback:

- Is the concept fun or gimmicky?

- Would you actually use something like this?

- What would make you pay for a premium version?

Happy to answer any questions about how it was built too (React + Node + WebSockets).

I built a free weekly newsletter that reads Reddit finance threads so you don't have to — just published Issue #001

Side project I've been working on: The Reddit Money Digest.

The idea came from noticing that the best personal finance insights on Reddit are always buried — either 800 comments deep, or drowned out by advice that's technically correct but missing crucial nuance. Meanwhile bad advice gets upvoted because it sounds confident.

So every Sunday I go through r/personalfinance, r/investing, and r/financialindependence, find the 3 most interesting discussions, and write up:

  • What the crowd got right
  • What they missed
  • Which viral advice was actually dangerous (Red Flag of the Week)

This week's issue covered the wave of "should I pause my 401k because of tariffs?" posts, the emergency fund milestone thread that hit 12k upvotes, and the never-ending avalanche vs. snowball debate.

It's free, no paywall. Built it because I wanted to read it and it didn't exist.

Issue #001

Happy to talk about the build, the content format, or the Substack setup if anyone's curious.

I built an AI wellness companion that actually remembers your patterns. Would love your feedback

I've been working on Keel for the past few months. It's a mental wellness app.

The idea is simple. Most wellness apps are great at collecting data but pretty terrible at doing anything useful with it. Keel tracks your daily check-ins, mood, sleep, energy and journals, then uses AI to actually connect the dots and surface patterns you wouldn't spot yourself.

A few things that make it different:

- AI sessions that remember your history and adapt over time
- Guided breathing & grounding exercises with audio
- Structured programmes (anxiety, sleep, stress, etc.)
- Premium insights like burnout risk detection and trigger pattern analysis
- Still in early testing with a small group before our TestFlight launch.

Would genuinely appreciate any feedback on the concept or the site.

Would you use a weekly/monthly email summary of your Actual Budget finances?

Hey everyone, I’m the developer of Bridge Bank, the tool that syncs European bank transactions to Actual Budget via PSD2/Open Banking.

I’m considering adding a scheduled email report feature, weekly or monthly, that summarises your Actual Budget data in your inbox. Things like spending by category, budget vs actual, net worth trends, and overspending alerts.

The idea is just a passive way to stay on top of your finances without having to open the app.

Would you use something like this? Weekly or monthly? And what would you want to see in it?

I am a firefighter building a "Life Inventory" app, probably for a customer base of 1. Would anyone else actually use this?

So I’ve spent the last few weeks building an iOS inventory app. Not because I’m a developer (I’m a firefighter) but because I couldn’t find anything that did what I wanted, and I have access to AI coding tools and apparently no self-control.

The premise is simple: I often forget where things are and whether I have them. Paracetamol in the car, the bathroom cabinet, the work bag, and the travel wash kit. A specific screwdriver that could be in any of four places. Sun cream that I buy every summer because I can’t remember if I used the last one. Searching for something I know I have, but can’t remember where I’ve put it, is really frustrating.

So I built something. It’s basically a tree of locations (house, car, work bag, whatever). You store items inside them at any depth: Garage > Third shelf > Small toolbox > Hammer. Then when you search “hammer”, it tells you exactly where it is.

Features I added because I couldn't stop myself:

Quantity tracking and expiry dates.

Minimum stock levels that flag when you’re running low.

Photo support for the actual shelf so you remember what you’re looking at.

A restock tab that builds a shopping list automatically.

I’m aiming for a video game style inventory for everyday life.

It also imports from a spreadsheet if you’re the sort of person who already has one of those. Which I was. Which probably tells you everything you need to know about me.

Here’s my honest concern: I’ve looked around and there’s basically nothing like this on the App Store. On one hand, gap in the market. On the other hand, maybe nobody wants this because normal people just... remember where they put things?

So I’m genuinely asking: is this something you’d use? It is not quite ready for the App Store yet, but I am trying to figure out if I should keep polishing it for public release or just keep it for myself. If there is actual interest, I might open up a beta.

Update on my 15min Crypto Polymarket bot — thank you so much for the support on the last post

Update on my 15min Crypto Polymarket bot — thank you so much for the support on the last post

last time I posted this here it was still pretty static (fixed entries, indicator voting, etc.)

since then I changed a lot under the hood and honestly the biggest shift wasn’t “more signals” — it was when the bot actually decides to enter

instead of forcing entries at a fixed point in the 15min window, it now continuously scores every moment and only fires when:

  • timing
  • momentum
  • signal quality all line up

so it basically learned where the actual edge is inside the window, not just what direction

what changed technically:

  • moved from a simple classifier → hybrid CNN + LSTM (so it actually learns sequences instead of snapshots)
  • recency-weighted training (recent market behavior matters more than old patterns)
  • dynamic entry optimizer → no more fixed entries, it waits for high-quality moments
  • EV + risk-based sizing → trades get graded (A/B/C) and sized accordingly
  • regime detection → behaves differently in chop vs trend vs volatility spikes

what’s interesting:

the bot trades less now, but the trades it takes are way cleaner

early version was basically:

“see signal → take trade”

now it’s more like:

“wait → skip → wait → ok this one actually has edge”

quick snapshot from today:

https://preview.redd.it/im7ynk7e06tg1.png?width=1080&format=png&auto=webp&s=2291f691e4a5fba6ddee31b9518f74edddabc27e

​mostly small consistent wins, a couple losses, but overall pretty stable behavior

nothing crazy, just clean execution

dashboard view:

https://preview.redd.it/yxh3gamh06tg1.png?width=1080&format=png&auto=webp&s=fcba1aab8316d3c90267f0e1a3bd110f753e95d0

this is where it gets interesting — you can literally see it skipping setups until the score crosses a certain threshold

a lot of time it just does nothing, which turned out to be way better than overtrading lol

still early obviously and I’m not pretending this is some magic system, but it’s behaving way less “robotic” than before

curious if anyone else here moved from fixed strategies → more adaptive / ML-driven setups

btw I ended up calling the bot Polybread lol

been running a small Discord around this and we somehow already hit ~100 members which is kinda crazy to me

if anyone wants to check it out / test it / just talk about

Join discord here

always happy about anyone who joins and gives the project a shot — feedback has been super helpful so far

I’ll keep posting updates here as things evolve
