Show HN: I built a self hosted recommendation feed to escape Google's algorithm
I created this chrome extension for myself where I track my own behavior locally and recommend myself content from platforms I want content from (youtube/twitter/quora/etc) in a feed. I made it public just in case anyone else was interested.<p>I would rather have control over my own algorithm and own the data. Also, it gives me flexibility. Turns out I do like these feeds just not when I don't own it haha. Let me know what you think of my implementation?

Show HN: PubKey – Communicate Privately in Anonymous Public Spaces
A little while back I remember seeing a user on a certain anonymous imageboard asking for an invite to a selective email host. Only after a few minutes did the guy realize the perplexity of the situation. How do you insure against a race condition in a public forum with no way to direct message?<p>Luckily, he nabbed the invite code, but it got me thinking about using PGP to provide a solution. This is meant to be a rough PoC and the UX is definitely not ready for the average Joe, but the functionality I'd like to think is there.<p>What catbox.moe is to dropbox is what I'd like this to eventually be to keybase. Btw, "this page uses NO SERVER" just means it's static. I'm not trying to fool anyone lol.<p>Edit: Source Code: <a href="https://codeberg.org/popcalc/pubKey" rel="nofollow">https://codeberg.org/popcalc/pubKey</a>

Show HN: CashGraphs – A securities portfolio optimizer
Hello,<p>This is a portfolio optimizer I made to help select portfolios for my clients. I'm a personal financial adviser. I generally put my clients in a mix of low-fee index funds and ETFs and I use this to set an appropriate allocation based on the client's risk tolerance.<p>I have been working on this as a side project to 1) improve the theoretical underpinnings of my investment recommendations and 2) improve my coding skills with frameworks like Vue and Torch. Here's the repository for the frontend: <a href="https://github.com/justinluther502/cashgraphfront" rel="nofollow">https://github.com/justinluther502/cashgraphfront</a>.<p>The frontend site is Vue 2 + Vuetify, and the backend is an AWS lambda function running the Torch optimizer. I am still working out kinks in the backend, particularly cold-start issues because the Lambda function has to load the entire Torch library (~2GB). This occasionally causes the AWS API Gateway to reach max timeout before the Lambda function finishes. Any tips on addressing this would be much appreciated. My first thought is maybe to pare down the Torch library used in the Lambda function because I am only using a small subset of the full library.<p>The optimizer function itself is designed to overcome several classic shortcomings in Modern Portfolio Theory (MPT) (<a href="https://en.wikipedia.org/wiki/Modern_portfolio_theory" rel="nofollow">https://en.wikipedia.org/wiki/Modern_portfolio_theory</a>). Unlike textbook implementations of MPT, this optimizer can utilize non-normal returns distributions, risk metrics besides variance, and can allow the user to specify tail behavior, such as asset correlations behaving normally most of the time but converging to 1.0 in severe downturns. Most of these "fixes" happen during the generation of custom "flavors", or asset selection universes. I have 3 flavors pre-built and there is some information on how they are constructed in the flavor selection page.<p>Any feedback greatly appreciated!<p>Justin Luther justinluther@lutherwealth.com <a href="https://www.lutherwealth.com" rel="nofollow">https://www.lutherwealth.com</a>

Show HN: Uber for Coding — Build product with bounties
Hey HN! After lots of dogfooding, we are now releasing Algora.io to help developers share bounties & easily meet new collaborators.<p>The problem: early-stage founders always have more work than people, tight budgets and no time. Hiring full-time engineers is often not an option, yet most founders would welcome contributions from new collaborators. Meanwhile, most developers welcome flexible work. However, today, all of this is hard.<p>Our solution: we built a Git GUI where you can pay developers and start collaborating with new ones, in just a few clicks.<p>On Algora you can share, reward and earn bounties right inside your code repositories. Algora also recommends developers/bounties that match your tech stack and makes it simple to start working together.<p>We are excited to welcome you on Algora, answer your questions and further improve our product and documentation with your feedback!<p>Thank you<p>- Ioannis & Zaf

Show HN: Interactive course about “everyday” data science
Last year, I wrote the book Everyday Data Science. It was #1 on HN! [1]<p>This year, I've been working with Jim Fisher on a new kind of interactive course. It's like a choose-your-own-adventure, except you'll learn Thompson sampling, differential equations, and Bayesian-optimal pricing.<p>After several months, the first two chapters are ready! Every word, button, and sound has been painstakingly crafted. Try out the first chapter to see what we mean! [2]<p>The course will be $99, but it’s $29 today, as a thanks for helping us build the next 8 chapters! Let us know what you think :-)<p>- Andrew Carr [3]<p>[1]: <a href="https://news.ycombinator.com/item?id=26253281" rel="nofollow">https://news.ycombinator.com/item?id=26253281</a>
