New best story on Hacker News: Show HN: We built an end-to-end encrypted alternative to Google Photos

Show HN: We built an end-to-end encrypted alternative to Google Photos 581 by vishnumohandas | 216 comments on Hacker News. 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

New best story on Hacker News: Show HN: With a 9-5 job and 2 kids I have finally finished my first MVP

Show HN: With a 9-5 job and 2 kids I have finally finished my first MVP 477 by mrhichem | 189 comments on Hacker News. Hello HN crowd. I worked on this project on weekends and evenings. I'm excited I made it into a presentable MVP, and it is so satisfying. I would like to get some honest feedback from this great community. I made https://ift.tt/3ykaazF , to scratch a personal itch. 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. Note: the app is not suitab

New best story on Hacker News: Ask HN: Google is confusing me with others in a harmful way – what can I do?

Ask HN: Google is confusing me with others in a harmful way – what can I do? 641 by AndreaVass | 188 comments on Hacker News. Hi Hacker News, I’m Andrea and I have a strange problem with Google that I’m wondering if any of you here can advise about. It’s affecting several people with the same name as me, whose lives are being impacted. In January 2021, I published a non-fiction book about a difficult, traumatic topic: my victimization and sex crimes that I witnessed toward other women. Because I am a victim, I chose not to put a photo of myself online. In fact, I have never ever taken a selfie nor had a photo of myself online. Four months after I published my book, Google created a knowledge panel for me and, because I didn’t have a photo online, they just grabbed a photo of another Andrea Vassell who lives in Canada and displayed it alongside my book and claimed this woman was the author. After spending weeks sending feedback and trying to get help from Google support, they finally

New best story on Hacker News: Show HN: Imba – I have spent 7 years creating a programming language for the web

Show HN: Imba – I have spent 7 years creating a programming language for the web 582 by somebee | 173 comments on Hacker News. Hey all My name is Sindre, and I am the CTO of Scrimba (YC S20). For the last 7 years, I have written all my web apps in a full-stack programming language called Imba. It compiles to JavaScript and its main goal is to make web developers more productive. I just launched a major overhaul of Imba, so I wanted to share it here on HN, in case anyone are interested in learning more about it. It is very opinionated, so some of you might not like it, but I would love to hear anyones feedback regardless. Constructive criticism appreciated! The backstory: Imba initially started in 2012 as an effort to bring the elegance and conciseness of Ruby into the browser, and also because I felt that JavaScript and the DOM should be more tightly coupled together. Over the years, I have taken inspiration from React/JSX, and also Tailwind. Since 2013, I have built several busines

New best story on Hacker News: Launch HN: Heimdal (YC S21) – Carbon neutral cement

Launch HN: Heimdal (YC S21) – Carbon neutral cement 565 by marcuslima | 206 comments on Hacker News. Hi HN, I’m Marcus, I’m the co-founder of Heimdal together with Erik ( https://ift.tt/3ykHhEs ). We remove atmospheric carbon dioxide and trap it in materials that are used to make cement. More CO2 is trapped in our process than is re-emitted in cement production. Concrete is responsible for 8% of global CO2 emissions. Cement is usually made from mined limestone, which is one of the largest natural stores of carbon dioxide. Using that to make cement is a bit like burning oil. The world is addicted to concrete, so this problem is not going away. We make synthetic limestone using atmospheric CO2, such that when it is used to make cement, the process is carbon neutral. We were both master's students in engineering at Oxford University in the UK. I decided to write my dissertation on direct air capture of CO2. While looking through existing solutions it struck me that none were suffic
