Show HN: CashGraphs – A securities portfolio optimizerHello,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.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: https://github.com/justinluther502/cashgraphfront.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 pa

Ask HN: Optimizing database table for user-made queries?Let's say you have have a large-ish database table of product orders, and you'd like to allow users to query it with an API, using several different filter and sort options, and of course supporting pagination.What would be the best strategy to optimize such query? Creating an index for every possible combination of options doesn't seem practical. How do large companies handle queries like [0], with 20 different filters and 10 different sort options?In our particular case, we use a MySQL db in AWS RDS.Tangentially, can you recommend any good books/resources with real-world usage patterns, and examples of the entire process of analyzing and solving database-related problems in growing web applications? Ideally written from the problem perspective, rather than just a reference of available db functionalities.Thanks![0] https://shopify.dev/api/admin-graphql/2022-01/objects/Product#query-products

Show HN: AMAZ3D – Optimize Asset in the CloudHi, My name is Leonardo Locatelli and I work for ADAPTA studio, a recently constituted spinoff of Politecnico di Milano (www.adapta.studio).Recently we developed a cloud service that allows users to optimize 3D assets by reducing the number of polygons directly from your browser but, to build something really useful, we need feedback from experts in 3D modeling and game development. Our team is composed mostly by mathematicians and software engineers so we appreciate feedback from people with complementary competencies.That's why we are giving people the possibility to try our software free of charge with some limitations on the number of optimizations everyone can do each month. What we ask is only some feedback and if you want, some suggestions about the main pain points for you in the development of 3D real-time apps.Here is a link to a video detailing its usage: https://www.youtube.com/watch?v=gfvCdONP9BUThe idea came from an algorithm I and some colleagues developed in our Master

Who is doing the best job at route optimization (traveling salesman)?I work for a small regional logistics company, and our CEO remarked the other day that he would be willing to spend thousands per month for a reliable route optimization service.I felt this pain myself the other day. Our network was overloaded due to normal Christmas peak coupled with quarantine purchases and UPS/FedEx turning away excess volume. I’m not an ops guy but I volunteered to go out and make deliveries in my wife’s SUV. I wrote the React Native app our drivers use to make deliveries, and I thought it would be a good chance to see how my app performed in a real world scenario. Well, the app did a great job but the backend process that optimizes drivers’ routes left me thinking we can do better. More than once the route order would have taken me right by addresses that were down the road from each other.I’m not sure exactly what the problem is really, and will be digging into that with our existing service. Maybe the larger number of residential addresses we deliver to these da
