Show HN: NLP Flashcards for Most of the Internet Hello HN! We're Sam and Kanyes. We're building an extension to help you remember what you read online. We're calling it Ferret [1]. When you open Ferret on an HTML page, it generates recall-based questions + answers to reinforce key concepts with NLP. Consider the following toy example where we open Ferret on an explanation of Bayesian statistics. [2] Q: What does the frequentist interpretation view probability as? A: the limit of the relative frequency of an event after many trials Q: What is often computed in Bayesian statistics using mathematical optimization methods? A:The maximum a posteriori We do this by (1) Parsing the DOM tree of an HTML page for tags on the client, and segmenting these into preprocessed chunks (2) Performing inference on question-generation with a T5-base model pretrained on SQuAD (3) Extractive question-answering with the chunk & question we've generated with RoBERTa, also pretrained on SQu

Show HN: A C# library to help you enforce a Given-When-Then structured Unit test I always strive to write better, clean and readable code. But I often find unit tests are hard to read, and especially harder to quickly identify what are the important pieces, or even what the test is testing about. So I came up with this lightweight library to help enforce unit tests with a Given-When-Then structure. I hope you find this useful.

Show HN: I developed a native macOS client for EC2/S3 console Hello HN: Here is the link https://ift.tt/3kuuEAS After forgetting to turn off a p2.xlarge instance for a week, I got so mad at myself I learnt swiftUI to build a native macOS console for most of the actions I do on the web AWS console. I didnt want to use electron or other non native frameworks. Most importantly I just wanted it to know how much a certain instance costs right now, no matter its state, its type, its lifecycle(like ondemand or spot) and the costs associated with the EBS volumes attached including their IOPS/throughput and etc. It also has a S3 object browser, and a drag and drop UI to upload your files so that you can make S3 your own personal dropbox. I dont track or store anything, you just query the aws api. Sorry its a paid app, if anyone wants to try it and cant afford it let me know, I can send it to you. I think this can be useful and cost saving for individuals that spend more than 50usd per month on

Show HN: We built an end-to-end encrypted alternative to Google Photos Hello HN, Over the last year we've been building ente[1], a privacy-friendly, easy-to-use alternative to Google Photos. We've so far built Android[2][3], iOS[4], web[5] apps that encrypt your files and back them up in the background. You can access these across your devices, and share them with other ente users, end-to-end encrypted. You can also use our electron app[6] to maintain a local copy of your backed up files. We've built a fault-tolerant data replication layer that replicates your data to two different storage providers in the EU. We will be providing additional replicas as an addon in the future. We're relying on libsodium[7] for performing all cryptographic operations. Under the hood it uses XChaCha20 and XSalsa20 for encryption and Argon2 for key derivation. We have documented our architecture[8] and open-sourced our clients[9]. We did a soft-launch on r/degoogle[10] sometime ago, and ha

Show HN: Degen Raffle – A raffle built on Ethereum Hey HN! I've been working on this idea off and on for a few weeks now and I figured it was time to show it to folks before continuing to build it out any further (hence the terrible UI). The idea is this: A smart contract that allows players to win the tokens in the contract in proportion to the number of tokens they've depositing into the smart contract. For example, if you and another player enter a round with 1 token each, you both have a 50/50 shot of winning the other's token. Here's the catch. Anyone can end the round at any moment, even people who haven't deposited any tokens. The contract is currently deployed to Rinkeby and I currently hold all of the Degen Raffle Tokens (DRT) needed to enter the raffle. If you're interested in playing, let me know and I'll send you a few million. https://ift.tt/3zpITx9 August 28, 2021 at 10:41AM

I myself trade options as a hobby, and I didn't find a screener that satisfies my need to be able to explore raw options data freely and without preset constraints. So I made this app that allows playing with options market data and extract interesting opportunities. The techs used: - Laravel + Jquery + Mysql - Tradier API for market data - DigitalOcean for hosting - OVH for domain name It costs me 5$/month to run the website. I'll be glade to continue if it proves to be a viable product in the long run and maybe I will take it to the next level and try monetize it.

Show HN: Hacker News Summary Service (HNSS) I'm Sid Sijbrandij and I love reading Hacker News. I almost always read the comment section and when there is a summary of the article in there that is frequently helpful. But most articles don't have a summary so I want to hire someone to create more summaries. I hope that this will make Hacker News more enjoyable and efficient to use for its readers. Many times it takes a while to figure out what the article is about, a summary would allow people a quick way to see if they are interested in investing that time. There are potential downsides: 1. People only read the summary and not the full article. 2. The summary might not be clear or correct. 3. People who already read the article don't want to see the summary. With a one month experiment we should have a better idea if HNSS is worth it. If it is here to stay we can also see if the summary can become an official part of HN. The writer of the summaries should: 1. Be able to do t
