<a href="">Ask HN: It's 2022. Where should I direct the youths to learn about programming?</a>

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?

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 Windows. > https://ift.tt/XELlxw9

<a href="">Show HN: Linen – Make your Slack community Google-searchable</a> 
25 by cheeseblubber | <a href="https://news.ycombinator.com/item?id=31168882">8 comments</a> on Hacker News. 
Hi HN! Kam here. I’m the founder of Linen.dev https://linen.dev , a website that makes your public Slack community Google searchable. Linen will sync your Slack threads and make it SEO friendly so your community can find Slack content that was previously hidden. Previously I worked on a popular open source project which had a sizable Slack community. Slack was great for engaging with community members and with early sales. However as community scales Slack becomes this black hole where context becomes lost. Most public communities can’t afford to pay for several hundred/thousand members so they are limited to 10,000 free messages. You run into the problem of people asking repeat questions and not searching in Slack. It also doesn’t help that the Slack UX encourages posting and not searching. We experimented with Github discussions and Discourse but didn’t want another channel to maintain and split the community on. With Linen I wanted to build a tool that is very low maintenance without changing my current workflow. By making it search engine friendly and putting it on a website the community members can find answers to repeat questions before ever getting into your Slack channel. Linen is the first result that comes up on Google if you search for “seeing a weird issue with flyte” https://ift.tt/q3dNS8l... or “replace beast http with proxygen” https://ift.tt/9hdYeu6... . As a side effect of syncing conversation to a website you end up with a very long tail of unique and relevant content for your community. Linen is free to use and get setup but I offer a paid version (I am still figuring out the pricing model for it) where you can get the content redirected to your own subdomain where your domain gets all the SEO benefits. Linen is built with Nextjs, Node, Typescript, React, Prisma for the ORM and using AWS aurora for the Postgres db. I chose Nextjs for the server side rendering capabilities and wanted to share types between client side with Typescript. I’ve also enjoyed working with Prisma as the ORM since you don’t have to write a lot of boilerplate with other ORMs. I've also been pretty happy with Vercel and Nextjs especially with the server side rendering and client side caching it provides. Here are a few communities on Linen right now: https://ift.tt/i5UDWm8 https://ift.tt/5TNdAIH https://ift.tt/vMtImUT https://ift.tt/gp0lomw https://ift.tt/gFdNQAV https://ift.tt/UmWlTXw The product is very simple right now but I want to add features like related questions detection with semantic similarity, integrating with Github to notify the thread when it is finished, auto thread detection for conversations that aren’t in thread form. You can sign up for free today at https://www.linen.dev . I am doing manual onboarding at the moment to get better feedback and to manually walkthrough some of the less polished parts of the boarding flow. p.s. I’m actively working on supporting Discord on Linen so would love to hear from anyone that is interested

New top story on Hacker News: Show HN: Sqwok – A social chat alternative to Twitter and Reddit

<a href="https://sqwok.im">Show HN: Sqwok – A social chat alternative to Twitter and Reddit</a> 
31 by holler | <a href="https://news.ycombinator.com/item?id=31160302">3 comments</a> on Hacker News. 
I previously did a Show HN late Dec 2020: https://ift.tt/tDFujce 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 to use it myself and felt that existing chat apps weren't designed for open public discourse in the way Reddit/Twitter are but for threaded comments & mostly unidirectional communication. This past year I’ve been very grateful to have a group of people continuously show up, offer support of the site and the idea, encouraging me to continue. Without those people I would have probably gave up! But alas I want to see this through and I believe now is the moment to make it happen. Since the last Show HN I’ve added: - markdown support in chat messages, post text, and user bio in profile (soon coming to full text post). - User profiles including bio, location, photo avatar, and chronological post listings. - New “who’s online” list that shows the top 10 ppl online and helps steer people to active conversations. - @mentions now work in posts, user bios, as well as chat messages. - Email notifications to be alerted when someone @mentions you. - Settings pages with ability to change password, delete account, and manage notification settings. - Upgraded image handling to support higher res photos with upcoming features allowing enhanced viewing. - Major refactor of the chat handling to stabilize it and fix many bugs with presence, locations, etc. - Many improvements to the codebase, frontend, backend, UI, tests, etc - Updated mobile web UI that drops you straight into the chat in a single view. - Ability to toggle full width chat view on desktop. - Live message counts displayed on the post list items that are updated in realtime. - Updated location handling for realtime location display. - Backend stability & aggregate analytics. Through Sqwok and particularly through the last Show HN I've met & got to know numerous people living across the entire Earth from Laos to Europe to Africa, all through a silly piece of software that for some reason seemed like the thing to work on. Truth be told there is much, much more I want to do with this. I believe now is the perfect time with the state of existing social networks and I’m hoping to find more people to support the site and help drive it to the next level. Let me know if you have any questions, Thanks!

New top story on Hacker News: Show HN: DTL: a language and JavaScript lib to transform and manipulate data

<a href="https://getdtl.org/">Show HN: DTL: a language and JavaScript lib to transform and manipulate data</a> 
33 by jk0ne | <a href="https://news.ycombinator.com/item?id=31098205">7 comments</a> on Hacker News. 
DTL is a project that began it's life as part of a another piece of software for a startup I founded a few years ago. For that project I needed a way to describe how to rewrite data in a portable way. I needed to be able to create the rules on the fly and store them in a database, I needed them to be able to describe transformations I hadn't thought about, but also needed them to be safe and predictable. Though the startup didn't survive, the language I made was so useful to me I felt I had to extract it and make it usable to everyone. DTL is the result. Though the npm module is relatively new, the language itself has been in use in production systems for years. Over the past couple of years I have been working to make it more accessible and useful to newcomers. Though it's really powerful, I tried to make it easy to use and simple to understand so that you can get up to speed quickly and use only as much as you need. To summarize: DTL is a javascript module and related CLI tools that are really handy for transforming data from one format to another. It's made to allow you to specify your transformations as data (JSON by default) which means they are easily shared from frontend to backend and vice versa, as well as making them easily stored in databases, etc. It can be used as part of your project to transform data between APIs, between the frontend and your database, etc. and can do simple mappings as well as complex calculations. It can also be used for validation and is really handy for extracting useful information from large / complex datasets (there are some great examples of this you can try on the website). The CLI tool (dtl) is like jq on sterooids, allowing you to slice, dice and remap csv, yaml, json or even plaintext data doing anything you can describe in a DTL transform. If you ever wished you could `grep` in complex data structures, today is your lucky day. :) I'd love any feedback you have and if you think of anything it doesn't have that it should, I'd love to hear that too.

14 by electric_muse | <a href="https://news.ycombinator.com/item?id=31098065">10 comments</a> on Hacker News. 
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’s also an interactive Gantt & Timeline view. *Spreadsheet is a generous term for now. Formulas are still on the roadmap. As are many true “spreadsheet” features. But we’re working towards it. Our roadmap is public, here: https://ift.tt/gd821mE And for VueJS devs, we eked out more performance from Vue 2 by modifying the core, documented here: https://ift.tt/4KdYESi... For database geeks, you might enjoy learning about the realtime graph DB we built to power the product: https://ift.tt/ZWoVjHP I’ve seen so many great companies start out by launching on HN. It’s quite a special personal moment finally to be sharing with you all. I’m happy to answer questions, take criticism, and generally hear what you think.

Hey HN, I’m an engineer at Supabase [0] and one of the creators of this demo. My team and I have been working hard to bring developers the next version of Supabase Realtime. The current version of Realtime [1] is a Change Data Capture (CDC) server for a PostgreSQL database that broadcasts changes via WebSockets to authorized subscribers. It’s written in Elixir/Phoenix. The server utilizes PostgreSQL’s logical replication functionality, which writes database changes to Write-Ahead Logging (WAL) segment files, and a replication slot, responsible for managing and retaining WAL files. Database changes are polled from WAL by the server using PostgreSQL’s replication function pg_logical_slot_get_changes and changes converted to JSON objects using the wal2json [2] extension by setting it as the output plugin. Security is enforced through two checks - each check ensures only authorized client subscribers are sent database changes. The first check validates a JWT that is sent by clients subscribing to database changes. This JWT must contain an existing database role and optional claims, both of which can be referenced in Row Level Security (RLS) policies. Every valid client subscription is then inserted into the realtime.subscription table with an assigned UUID, database role, and claims. The second check calls the realtime.apply_rls SQL function from Write Ahead Log Realtime Unified Security (WALRUS) utility lib [3]. This function takes the database changes, executes a prepared statement to verify if the database role and claims have SELECT permissions on the changes, and outputs an array of authorized UUIDs. Then, the server finds all the subscribers whose UUIDs are in that array and broadcasts the changes to them. The next version of Supabase Realtime will offer three features: Broadcast, Presence, and Extensions. Broadcast, our Pub/Sub offering, can be used to pass ephemeral data from client to client such as cursor movements. This runs on a distributed cluster of nodes built on top of Phoenix PubSub + Channels. Presence, can be used for tracking online/offline users and their state. This is built into Phoenix, and uses replicated state across a cluster using an Observe-Remove-Set-Without-Tombstones (ORSWOT) CRDT [4] which prefers adds over removes when resolving conflicts. Extensions, are a way for the community to add additional functionality to take advantage of the WebSocket infrastructure. We have converted the existing Change Data Capture system to an extension that supports connecting to multiple customer databases (multi-tenancy). Other possible extensions include listening to other databases like MySQL and getting stock market events server-side [5], then broadcasting them to connected clients. This demo is built using a Supabase project, Supabase Realtime, and Next.js and deployed on 20 Fly [6] nodes located around the world. You can find an introduction and walkthrough of the demo here [5]. Supabase Realtime is entirely open source and you can find the demo code here [7]. Once we have stabilized the release we will add it to the self-hosted offering [8]. This demo is a way to highlight the upcoming features and gather feedback/ideas. Feel free to ask me anything and let me know what you think! [0] https://supabase.com [1] https://ift.tt/AZF5HfN [2] https://ift.tt/nXetGsa [3] https://ift.tt/uSMWDyF [4] https://ift.tt/608qPmw...
