Launch HN: Narrator (YC S19) – a data modeling platform built on a single table https://ift.tt/34bcMD0

Launch HN: Narrator (YC S19) – a data modeling platform built on a single table Hi HN, We’re Ahmed, Cedric, Matt, and Mike from Narrator ( https://www.narrator.ai ). We’ve built a data platform that transforms all data in a data warehouse into a single 11-column data model and provides tools for analysts to quickly build any table for BI, reporting, and analysis on top of that model. Narrator initially grew out of our experience building a data platform for a team of 40 analysts and data scientists. The data warehouse, modeled as a star schema, grew to over 700 data models from 3000+ raw production tables. Every time we wanted to make a change or build a new analysis, it took forever as we had to deal with managing the complexity of these 700 different models. With all these layers of dependencies and stakeholders constantly demanding more data, we ended up making lots of mistakes (i.e. dashboard metrics not matching). These mistakes led to loss of trust and soon our stakeholders were

Show HN: Go Budget, a full-featured manual budget tracker built with Flutter https://ift.tt/3cE7L9K

Show HN: Go Budget, a full-featured manual budget tracker built with Flutter Over the weekend I launched Go Budget, a side project of mine from the last few years that originally was just an Android app used by me and my wife, but was recreated in Flutter during the pandemic. https://gobudget.io [0] App Store [1] Google Play [2] Privacy Policy Go Budget lets you set up your income and bills (repeating expenses), automates tracking them wherever possible, then makes it as painless as possible to log every day purchases. For individual users the app is free/adfree. I offer a premium subscription that allows you to back up budgets online and invite others to join your budgets to stay in sync. My experience with Flutter was nothing short of amazing, and I think the end result turned out pretty nice. I'm happy to answer any questions about Flutter or anything else related to the app. -- The backend stack is pretty basic: - Flask + Redis + Gunicorn + Traefik running in docker on a Digita

Show HN: DevUtils.app – Developer Utilities for macOS https://ift.tt/3cCko52

Show HN: DevUtils.app – Developer Utilities for macOS This is a project I've been working on since the start of Covid-19. I built an app so that I don't have to put data into online tools like JWT debugger, JSON formatter, URL decoder, etc... https://devutils.app The app works entirely offline and is open-source. I'm selling the pre-built version of the app to earn some revenue for my time. If you want to try the app but can't afford the price or don't have XCode to build the app, drop me an email (my profile), I'll be happy to provide you a free build. I would love to hear all the feedback/suggestions. Thanks! September 27, 2020 at 09:47AM

Launch HN: Scrimba (YC S20) – Interactive video for learning to code https://ift.tt/32WBPdB

Launch HN: Scrimba (YC S20) – Interactive video for learning to code Hi all, I’m Per, co-founder of Scrimba. We are building an interactive video format for teaching and learning how to code. The main benefit is that students can pause the video and edit the code whenever they want. We think this is needed is because over 70% of people who are trying to learn to code today use videos. But since videos aren’t interactive, students end up mirroring the instructors’ code line-by-line in their local code editors. This is time consuming, and it often causes problems with local dev environment setup. Scrimba solves these problems as it enables students to pause the screencast and modify the instructors’ code directly inside the player. So when a Scrimba student feels confused, she jumps into the screencast and plays around with the code (editing, running, debugging) until she’s made sense of it. As a consequence, she learns faster. Technically, this is possible because we have merged the IDE

Show HN: Debut – a retro terminal PowerPoint clone https://ift.tt/3cca8Aq

Show HN: Debut – a retro terminal PowerPoint clone https://ift.tt/3my8IVH As part of work I was tasked with doing a presentation on a part of the Agile Manifesto, so as a way to make it interesting I initially decided to do it as an animated CLI app. Then I remembered curses existed! And a weekend later I ended up with a mini-framework for doing your own presentations in the terminal complete with borders, colours and keyboard interaction. It's also 100% Python with no external dependencies, so feel free to clone it and run it as the readme states. September 19, 2020 at 03:12PM

Show HN: Building the next-generation learning experience https://ift.tt/35Jq245

Show HN: Building the next-generation learning experience If you reflect a bit on how you learn, you will probably find that in order to acquire a skill or some level of expertise on a subject, you take 5 steps that make up your learning behaviour. 1. You find the learning materials for the subject. 2. You input these materials into your brain through reading and listening. 3. You process the new information through memorising and associating in order to construct a new thinking model. 4. You practise by solving problems that are designed for learning, or by having basic conversations in the case of learning languages. 5. You apply the new skill you just acquired and start creating values for the world with it. What Astrasum does is that we are hacking learning. We want to accelerate your learning by helping you become better and better at each one of these steps with our technology and growing community. We are still working to integrate AI and VR into our features, but they are alrea

Show HN: Web Push Notification for Shopify Store Owners https://ift.tt/3kmYGEY

Show HN: Web Push Notification for Shopify Store Owners Hi Folks, We recently launched our app, https://ift.tt/32BUJX5, on Shopify App Store for store owners to promote their stores using push notifications. I am sure almost here everybody knows about push notifications, but just in case you are not, they are small popups you see on your mobile whenever you receive an email, sms or any other notification. Along with mobiles, most of the modern browsers on desktops support push notifications. Shopify store owners can use push notifications to send automated abandoned cart notifications, new order confirmation, shipping information. You can also run marketing campaigns to send notifications to your subscribers for new launches, weekend offers etc. Its a free app for now with no limits on usages. We are inviting and looking forward to the feedback from everybody in the community, Please install the app from https://ift.tt/32BUJX5 September 17, 2020 at 12:38PM

Launch HN: Tappity (YC S20) – Keeping kids entertained with science https://ift.tt/35gov5o

Launch HN: Tappity (YC S20) – Keeping kids entertained with science Hey HN -- I’m Chad, and I co-founded Tappity ( https://ift.tt/2F4JDRv ) with my friend, Lawrence. We’re building a healthy alternative to Youtube that entertains and educates kids (4-10) with interactive lessons—starting with science! Tappity’s story began ten years ago when I developed an app for my Biology professor to teach kids about evolution. It was my first time building a product for kids, so I learned a ton about designing for an audience who couldn’t read or sit still for very long. Also, their brutally honest feedback was refreshing! We ended up getting 20,000 downloads, and I learned kids love interactions. After that great experience, I continued to create apps for kids on the side for fun. About two years ago, parents started paying for one of these apps. Kids loved a segment we had shot on a whim at our friend’s house, in which they could interact with a real live science teacher. Parents were excited, t

Show HN: Bookmark with Scheme Lisp REPL https://ift.tt/35fiGoI

Show HN: Bookmark with Scheme Lisp REPL You can use it to run Scheme interpreter on any website, if it don't have content security policy (like Hacker News). You can use it while learning Lisp (Scheme) or when testing some code from online book or PDF (at least in Chrome). The link to Bookarklet can be found in this link: https://ift.tt/2Zf2Ir2 The bookmark use devel version of LIPS Scheme, it will be released version after 1.0.0 is finished. Latest version is very old, devel and beta versions have lot of changes. LIPS scheme have almost fully working lisp macros and hygienic macros systems (syntax-rules) but still no call/cc and TCO.

Show HN: Linux sysadmin course, eight years on https://ift.tt/2Fc2LMM

Show HN: Linux sysadmin course, eight years on Almost eight years ago I launched an online “Linux sysadmin course for newbies” here at HN. It was a side-project that went well, but never generated enough money to allow me to fully commit to leaving the Day Job. After surviving the Big C, and getting made redundant I thought I might improve and relaunch it commercially – but my doctors are a pessimistic bunch, so it looked like I didn’t have the time. Instead, I rejigged/relaunched it via a Reddit forum this February as free and open - and have now gathered a team of helpers to ensure that it keeps going each month even after I can’t be involved any longer. It’s a month-long course which restarts each month, so “Day 1” of September is this coming Monday. It would be great if you could pass the word on to anyone you know who may be the target market of those who: “...aspire to get Linux-related jobs in industry - junior Linux sysadmin, devops-related work and similar”.

Show HN: Real Time Stream Processing Startup https://ift.tt/35872Mx

Show HN: Real Time Stream Processing Startup We are working on a product which makes stream processing easy for data analysts and data scientists. It’s a higher level alternative to Flink, Kafka Streams and Spark Streams. As well as making stream processing simpler, we also felt that lots of people were building these AWS stream processing platforms based on Kafka and something like Flink so wanted to offer this as a service. We would welcome any input on the space or approach: Home page: http://Timeflow.systems Demo: https://youtu.be/fGfgBaHXOkE September 3, 2020 at 09:27PM

Launch HN: Slapdash (YC W19) – A uniform, low-latency interface for cloud apps https://ift.tt/3boeKmu

Launch HN: Slapdash (YC W19) – A uniform, low-latency interface for cloud apps Hello HN, I'm Ivan, one of the founders of Slapdash ( https://slapdash.com/ ). Slapdash lets you work across all of your cloud apps at desktop speed, sort of like an OS for cloud apps. We have built a uniform, low-latency data browser (kind of like Finder) as well as a unified command line-like interface (kind of like Spotlight) for the applications you use at work. When we left our big company jobs, one of the difficult things to part with was the tooling. Companies like Facebook & Stripe build a class of tools internally that unifies all the employees and any collaboration apps, so you can find anyone or anything the company knows. Everything is just a quick search away.[0] It’s quite a useful way to work. Common questions in day-to-day work are easy to answer. What’s the history of this code abstraction? What are my colleagues working on? What’s the story with this customer? Building such a system
