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
640 by vishnumohandas | 229 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 did a soft-launch on r/degoogle[10] sometime ago, and have since then ironed out issues and polished the product. But we are far from where we want to be in terms of features (object and face detection, location clustering, image filters, ...) and user experience. We are hoping to use this post as an opportunity to collect feedback from fellow hackers. If there's anything we can do better, please let us know, we would like to. Best, - Vishnu, Neeraj, Abhinav [1]: https://ente.io [2]: https://ente.io/apk [3]: https://ift.tt/3BptQnU [4]: https://ift.tt/3sU3aIO [5]: https://web.ente.io [6]: https://ift.tt/3t4idje [7]: https://ift.tt/2WrzG9r [8]: https://ift.tt/3jpTq5S [9]: https://ift.tt/3zrzLId [10]: https://ift.tt/3BoGkvI...

Show HN: With a 9-5 job and 2 kids I have finally finished my first MVP
478 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 suitable for phone screens yet, although this is a planned feature.

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 deleted the woman’s photo, but then promptly replaced it with another Andrea Vassell who is a pastor in New York. She, the pastor in New York, wrote to me that she has been “attacked” because people believe she is me. I contacted Google again and asked them to please delete the knowledge panel because I did not have a photo on the Internet; therefore, any photo that they displayed alongside my book would be of the wrong person. By this time, some of the characters in my book were also being negatively affected because now it seemed they had harmed a pastor of a church. I kept contacting Google and finally at the end of May, the knowledge panel was deleted, only to return a week later with a photo of a man who had been fired for his threats toward me. That photo remained until July 2021, and was then replaced with the pastor in New York again, although this time it’s a different photo of her. I know that I am not a celebrity or an important person, but I spent two years writing a very difficult and personal book and to have a large corporation come along and continuously and consistently misrepresent my work and cause distress to others is becoming exceedingly stressful for everyone involved. I contacted the Federal Trade Commission and they told me to contact the BBB and IC3.gov. I received an automated response from BBB and I don’t understand the reasoning behind contacting IC3.gov. I am currently working on a second book which I assume will be added to this knowledge panel with the photo of the wrong woman. I would greatly appreciate any input about how to get this corrected so that I and others can move on. I know this is probably just an algorithmic glitch, but it’s affecting not only me but several others, and at this point I have no idea how to get Google to take it seriously.

Show HN: Imba – I have spent 7 years creating a programming language for the web
631 by somebee | 184 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 business-critical apps in Imba, so this is not a toy project or an academic exercise, it is extracted from a real project trying to solve real problems. Today, we are currently a small but passionate community of devs who use Imba all over the world. The nitty-gritty details: As mentioned, Imba compiles to JavaScript, and it works on both the frontend and backend. The quickest way to get a feeling of how it works is by checking out this video: https://www.youtube.com/watch?v=8XS5q9xhaMc Alternatively, here is a list of the main benefits of the language: * Clean syntax with built-in tags and inline styles * Imba's Memoized DOM approach is *an order of magnitude* faster than Virtual DOMs (Vue, React). Learn more here: https://ift.tt/3xUlp1B... * Imba works with Node and the npm ecosystem, and integrates tightly with both JS and TypeScript * Blazing-fast dev/build tools based on esbuild Each of the benefits above are explained more thoroughly in our docs here, so please check it out if any of the above points spark your interest: https://imba.io With this version I feel that I am very close to my vision for what Imba should be. In other words; it is finally ready for public consumption. I'd wholeheartedly advice you to look into it and give it a whirl if you are interested in web development :) Hope you like it, and please share any feedback you might have in the comments! PS! We're also hiring Imba developers at Scrimba - see https://ift.tt/2VaOOHF . We don't expect you to be a seasoned Imba developer, but we expect you to pick it up fast :)

New best story on Hacker News: Launch HN: Heimdal (YC S21) – Carbon neutral cement
Launch HN: Heimdal (YC S21) – Carbon neutral cement
562 by marcuslima | 204 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 sufficient. They all operated a circular process that left them with gaseous CO2 that needed to be stored somewhere. A circular process is one that uses a sorbent to trap atmospheric CO2 but then re-releases the trapped CO2 as a pure gas stream to regenerate the sorbent for re-use. We don't have enough high-quality cheap stores of CO2 to justify such an approach. Storage must be permanent and safe. We realized that by taking a linear approach, we both make the process of capturing CO2 profitable and avoid the problem of where to store the CO2. We make sorbents for trapping CO2 in the form of mineral carbonates, these compounds are inert and trap CO2 for millions of years. They can also be commercialized as raw materials for making building materials including glass and concrete. In one step we solve three key problems of carbon capture: 1. How to trap CO2 energy efficiently 2. How to store the CO2 3. How to make money while doing all this. Specifically, we use renewable electricity to extract dissolved oceanic CO2 as mineral carbonates of calcium and magnesium by contacting seawater with our proprietary alkaline sorbent. These mineral carbonates are important ingredients in cement as well as other building materials. The undersaturated ocean then re-absorbs an amount of atmospheric CO2 equivalent to the amount we removed when reacting with our sorbent. Effectively, the world’s oceans become our air contactor. There are other companies addressing emissions from concrete production, but they don’t address the unavoidable process emission from the raw materials used in concrete. Start-ups in this space have so far focused on curing concrete with CO2 at the end of the production process. These are great solutions that can create low-carbon cement, however they’ll never get to carbon neutral cement that the world needs. The 70% of emissions from production are not being tackled by anyone on the market today. Until now concrete producers have favoured capturing emissions at the point where they’re released as their “2050-solution”, ie. in the distant future. Point source carbon capture can expensively capture 80-90% of emissions. This solution has the same problem as circular DAC solutions where a method of permanent CO2 storage is needed. There is a trial $3B (!) project in Norway to pump CO2 into empty gas fields at a cost of ~$1000/tCO2. This is expensive and complicated engineering. On the other hand, all we need is renewable electricity and seawater. We make money from selling synthetic limestone to cement producers and commercializing parallel byproducts including green hydrogen and desalinated water. We also generate carbon credits from our process. We are currently negotiating with concrete producers to decarbonize their limestone supply. Response has so far been very positive with multiple LOIs signed with producers across Europe. We are also working with a construction company to build the world’s first carbon neutral houses this decade. We are currently building a demo plant just outside Oxford. It has the capacity to remove and store 1 tonne of CO2 per year. We will use this plant to make enough product that we can deliver to our commercial partners to confirm compatibility with their manufacturing set-up. Following successful testing, we will scale this up to replace all of global limestone mining; currently >2 billion tonnes of limestone per year. We're excited to hear any thoughts, insights, questions, encouragement and concerns in the comments below! Erik and I will be monitoring the thread over the course of today to answer any questions. Also feel free to reach out to me by email at Marcus.lima@heimdalccu.com.
