Show HN: Radiopaper – Troll-resistant public conversations 62 by evnp | 34 comments Hi HN! We're a bootstrapped team of 4 and have been building Radiopaper for around 16 months alongside other full-time, part-time, and consulting jobs. I wanted to highlight a couple of the unique characteristics of Radiopaper that may not be immediately apparent when browsing https://radiopaper.com/explore * It's possible to interact with Radiopaper entirely by email, and never log-in interactively. The notification emails contain context that explains that if you reply to the email, your message will be published on https://radiopaper.com * The key mechanism that makes Radiopaper different from other social networks, and more resistant to trolling and abuse, is that messages are not published until the counterparty replies or accepts your comment. You can read more about this in our manifesto at https://radiopaper.com/about The technical stack is a Vue/TypeScript app talking to an API backend...

Ask HN: It's 2022. Where should I direct the youths to learn about programming? 25 by slyrus | 30 comments So... Child #2 (18 yo) is interested in learning programming. Good "with computers" and proficient in level-appropriate math but didn't grow up as a hacker like his old man (I'll refrain from making him learn turtle graphics and BASIC). Where should I point the kid to learn the basics? I'm afraid that if I show him how to download (or, better yet, build) emacs, how to build SBCL, install SLIME, etc... and hand the kid copies of SICL and PCL someone will call child protective services on me. I imagine there was a time when the answer would have been java/awt, but those days seem long gone. Maybe there was a let's do it all in javascript phase, but that doesn't seem to be the answer today. So... modern starter pack? VS Code and Python? Tell him to learn Pandas/SciPy/NumPy? Are there any highly recommended online courses for learning this stuff? on...

Ask HN: Do you find it challenging to talk to your users? 20 by atomiomi | 11 comments One of the problems I faced when I had my first users on [just-diary.com](http://just-diary.com) is that I didn’t have any way to talk to them. Like getting feedback on using the product, asking them questions about what they want from it, and sharing some tips on how to use some features. Does anyone have the same problem? If yes, how did you solve it? on Hacker News. One of the problems I faced when I had my first users on [just-diary.com](http://just-diary.com) is that I didn’t have any way to talk to them.

Show HN: Xlibe: a serverless Xlib (X11) compatibility layer for Haiku 20 by waddlesplash | 1 comments Hello HN, While there are some projects that implement partial versions of Xlib APIs on non-X11 platforms for compatibility (most notably, Tk), I don't know of any others sophisticated enough to run Cairo and GTK applications (albeit with a few hacks). So I figured this might be technically interesting. As of now it just implements the base Xlib APIs, it doesn't implement XRender, GLX, XInput2, etc. (though it's more than possible, I just didn't see a need yet.) Cross-program interaction is also very limited, and there are plenty of X11 features that likely can't be implemented; but this works sufficiently well that GTK3 is now in Haiku's default package repositories, with GIMP and Inkscape atop it to boot, using this. And for the fun of it, I did try to compile Xnest (the X.org server variant running on top of Xlib) on top of this; it crashed on startup in the...

Show HN: A tool to seed your dev database with real data 18 by ev0xmusic | 2 comments A bunch of developers and myself have created RepliByte - an open-source tool to seed a development database from a production database. Features: - Support data backup and restore for PostgreSQL, MySQL and MongoDB - Replace sensitive data with fake data - Works on large database (> 10GB) (read Design) - Database Subsetting: Scale down a production database to a more reasonable size - Start a local database with the prod data in a single command - On-the-fly data (de)compression (Zlib) - On-the-fly data de/encryption (AES-256) - Fully stateless (no server, no daemon) and lightweight binary - Use custom transformers My motivation: As a developer, creating a fake dataset for running tests is tedious. Plus, it does not reflect the real-world data and painful to keep updated. If you prefer to run your app tests with production data. Then RepliByte is for you as well. Available for MacOSX, Linux and Wi...

Show HN: Sqwok – A social chat alternative to Twitter and Reddit 57 by holler | 28 comments I previously did a Show HN late Dec 2020: https://news.ycombinator.com/item?id=25470672 That was a great experience and in the past year I continued to develop the site to bring it to a level of stability and maturity that I felt necessary for it to have a chance to succeed. Sqwok is all about answering the question: Can we have better open conversations on the internet? I wasn’t satisfied with the existing means of discussing topics such as culture, history, politics, and technology through threaded comments, and was simultaneously impressed with Slack bringing the IRC experience to the browser for a more general but enterprise focused audience. I wondered why not create an open Slack-like chat app for general discussion? Not gamers or enterprise but rather for people to have open, kitchen-table discussion on the matters of the day (or just for fun!). I set out to build this because I wanted t...

Show HN: Two-way Jira sync in a collaborative spreadsheet and Gantt 16 by electric_muse | 10 comments Hello HN, Our startup nearly died 2 years ago. We kept losing customers to spreadsheets. And it made us see a problem right under our nose: everyone just wanted flexibility & speed from a spreadsheet. But they have to stay in sync with {Jira / Salesforce / insert SaaS app}. When we followed this thread, we discovered how broken the integration experience was for flexible products like Airtable, Smartsheet, Monday, and Google Sheets. Their big problem is that they transform external data into their own format. This makes setup harder, since you have to get the mapping just right. And often you can’t sync back. We took a different path when building Visor. We essentially made a data lake & ETL tool with a front-end. Visor integrates with your Jira instance, reads its schema, helps you import the right data, and lets you work in a flexible spreadsheet* that syncs both ways. There...

Recently, I decided it was time for an update. I use Linux on the often so it was important for me to purchase a laptop that was compatible. I bought 2 laptops, all of which I had to return in the last 2 months. 1. Dell XPS: I spent over 20+ hours with their support going back and forth. I also had a tech come to my house to replace my motherboard before I gave up and demanded a return 2. Lenovo Carbon X1: The laptop came with a faulty keyboard so I just returned it because I didn't want to wait 30 days for a mail-in repair or drive 2 hours to go to a "local" repair shop. They also made me order the laptop 3 times because their system kept cancelling it for whatever reason so it took an insane amount of time to just purchase the laptop (I spent ~6 hours to just purchase the laptop) M...

Plenty of folks have pointed out how the lack of native support for color doomed HyperCard. But I think it was really over when the web got started and replaced everything in the "personal content" space from underneath, so I decided to see if the idea of HyperCard would work as a web app. There are some missing pieces -- it's not perfectly compatible.
