Show HN: Restapp.io – SQL Data Modeling Tool in No/Low Code https://bit.ly/3RgKGwE

Show HN: Restapp.io – SQL Data Modeling Tool in No/Low Code Hey all! We've been working on RestApp V1 and this is our first time posting it on HN. It's an No/Low Code data modeling tool that enables you to build & maintain data pipelines with a visual programming interface. We don't store your data but we compute them through Apache Spark for query speed & efficiency. Here's some features: `Connectors: Connect to any source and destinations (DB, DWH and SaaS Applications). We currently support MongoDB, Snowflake, BigQuery, MySQL, MSSQL, SFTP (JSON, txt, csv, excel files supported), Hubspot, Stripe, GDrive (JSON, txt, csv, excel files supported). `Pipeline: Visual Programming Interface where you drag-and-drop SQL, NoSQL & Python functions instead of writing them to create a query and debug it easily. `Automation: You can automate your data pipeline (Job) through a scheduler. `Domain: Think of it like a workspace in which you can share securely your connectors and pipelines to specific users (colleagues, partners, clients...) We've designed this because as a data team member, we were writing a lot of long SQL queries with bad performances and we were getting headaches by debugging them. Now you can build, monitor and debug any kind of data pipelines with just Drag-and-drop built-in SQL functions to save you tremendous amount of time & effort. We're working on this continuously so we're keen to hear any feedback. Feature requests and critique are more than welcome. Try it out for free (30min of computing time offered each month): https://bit.ly/3E3glhW The Getting Started docs are here for anyone who wants to check this out: https://bit.ly/3LRbxOC and https://bit.ly/3fsiQ3c... https://bit.ly/3E3glhW September 28, 2022 at 11:14AM

Show HN: KaithemAutomation, the home automation system for coders and artists https://bit.ly/3RkruxO

Show HN: KaithemAutomation, the home automation system for coders and artists I've talked about this one on Reddit a bit, and I think it's finally about ready to talk about here. I started this project around 2013 for internal use, and GPL licensed it because I have no desire to own my own software business. Kaithem is, for the most part, somewhere between a SCADA and a Home Assistant clone, heavily focused on easy deployment with minimal tinkering. It allows for Python code based if-then events you edit via the web, along with web-editable HTML dashboards, but also includes loadable modules for more point-and-click style editing. One of these is Chandler, a scenes/cues manager that includes a simple visual scripting language inspired by ladder logic. It saves everything you create in Git-friendly plain text files, and is meant to integrate well with a linux system, with convenience features like using the user account username/password to log in. Device drivers created via an extension API, and can also be used in non-kaithem apps, via the iot_devices library. Drivers should be share-able and installable via pip. There's also basic builtin support for IP cameras, including sub-second latency streaming via websockets, and object detect recording. Out-of-the-box device support is pretty limited at the moment, consisting entirely of stuff I've had a use case for personally, but does include YeeLight, RTL433-supported sensors, SainSmart relay boards, and most anything ZigBee2MQTT can handle. In addition, there are tag points and alarms vaguely copied from SCADA systems, modules can make use of the tagpoint object, which is like a variable that hooks into the tag point system, every point gets a management page where you can set alarms, set up logging, which includes the ability to only log the min, max, or average over time, to save space, and override it's value. It uses only external dependencies found in the Debian repos, and does not include any crazy built in custom feature downloader thingy like some similar projects, nor anything that needs compilation. It does not use a database, separate web server, or any other thing that would require you to specifically configure the system in an unusual way, although some features can make use of MQTT, and it does depend on PipeWire being set up if you want to use the built in audio live mixer(You may also be able to use it with manually started JACK). It's 99% stable, used in real installs, and could probably be called v1.0 already, but there are unmaintained experimental features that will probably disappear(Anything that involves a custom nonstandard network protocol is on the chopping block, as per my philosophy of decustomizing technology, as is HTTPS support as that may be better done externally). https://bit.ly/3DZjwr3 September 28, 2022 at 06:11AM

Show HN: A curation of resources telling the story of Bitcoin https://bit.ly/3Sjxbxz

Show HN: A curation of resources telling the story of Bitcoin Spend the past couple of months creating a large curation of resources from the best Bitcoin educators. The goal was to create a wholesome journey that went beyond just talking about what Bitcoin is and how it works, but also helps newcomers understand why Bitcoin exists and why it can be such an impactful technology for people all over the world. I hope it can help people get a broader understanding of Bitcoin and allow them to make an informed judgement on its value to the world. p.s. I would love to make this community-driven and the GitBook is open-source. Do contribute if you would like to! It would be much appreciated. https://bit.ly/3SjxeJL September 27, 2022 at 06:59PM

Show HN: MockMechanics is now open source Hey guys, a couple of years ago I posted about MockMechanics, a visual programming language/sandbox building game that I've been working on and there was a very positive response [0]. Since then I've been implementing most of the things I promised in my first youtube video [1] and making it ready for an open source release and I'm happy to say it's ready [2]. I've also been building new things and showing them in the youtube channel. It's written in clojure and you can use it to create all sorts of machines, games, musical instruments, etc using little to no code at all. You've seen the piano, the tetris game, the clock the combination safe and so on but since then I've built a 3d printer, a robotic hand, a bubble sorting algorithm, a 7 segment display, a ball cannon, a paint program and more, you can see all these things in the youtube channel [3].

Show HN: Get conversational practice in over 20 languages by talking to an AI https://bit.ly/3rh9pGl

Show HN: Get conversational practice in over 20 languages by talking to an AI Hi everyone, Let me introduce you to Quazel, where we want to enable people to talk their way to fluency. We have all tried various language learning apps and tools, however, one aspect of language learning current services are really bad at is conversational practice. You might get a chat-like interface, but in the end, the conversation partner will only respond with a predefined "if the users say X I say Y". With Quazel that's completely different. In completely dynamic and unscripted conversation you can talk about pretty much anything you want. For example, you can try ordering food at a restaurant and even hold a philosophical discussion with Socrates. Additionally, you can analyze the grammar of your responses or use hints to help you out when you get stuck. We want to change how languages are learned from a grammar-centric approach to a more natural, conversation-focused one. https://bit.ly/3E22bxT September 27, 2022 at 10:18AM

Show HN: Clammer – share and discuss article excerpts with friends Clammer is a social platform for sharing and discussing excerpts from online written content. It's like Twitter but every post and thread stems from the facts, quotes, and insights you collect online, all tied back to the source. In fact, you can have a whole conversation without ever writing a single word. I made this because I was tired of rehashing vague opinions, the real juicy conversations are in the details. Would love to know if this resonates with anyone; any and all feedback is hugely appreciated. Demo: https://www.youtube.com/watch?v=ZU-4uMcNiGk https://bit.ly/3DXCoqn September 26, 2022 at 01:35AM
