Show HN: An interactive map showing live wind farm generation in Great Britain
GB Renewables Map an energy experiment created entirely in my free time (day job is visualisation at Octopus Energy).<p>It's an interactive map showing live generation for major wind farms in Great Britain, showing what each wind farm is generating both now and in the past, and where that generation is physically located.<p>Animated weather data is from WeatherLayers and shows current and historic wind conditions on the map, providing context to wind generation around the country.<p>History mode allows you to go back in time and see wind generation and weather conditions for a particular date and time. It's great for exploring days of record generation, such as the 21.6GW record on January 10th, 2023!<p>Prediction mode lets you see what wind farms are estimated to be generating using current wind conditions and model based on historic generation and wind speeds. Is a wind farm generating as you expect, or is there something to look into?<p>An experimental feature allows you to see what future wind farms could be generating today (or in the past!) if they were already built and operational. If you click the "sparkle" button on the map you'll get to see what the upcoming 3.6GW Dogger Bank wind farm is estimated to generate if it was operational today.<p>There's an "About" section on the site that goes into detail on the various public data sources and how some of the features work. I also document a lot of this on my Twitter @robhawkes if you're curious.<p>This is just the start and there are many more features to come!<p>Please let me know your comments and suggestions.

Show HN: A C++ web/application framework I have been building for the last 12yrs
Back then there were not a lot of frameworks for C++ like there are available now, gradually added serialization, reflection, orm, modules for apache|nginx, then started adding programming language integration and then finally added support for building on various Os'es and also support for most of the build tools out there.
Show HN: Ordently – Consciously plan your day and your life
I've been using a task management tool for the past 1 year that I built. A few months ago, I spent some time to make it more generic because my partner wanted to use it as well and she's been loving it ever since. Love her, but she's a bit biased.<p>Firstly, this is a todo app for your life. Existing tools are built around how we work as employees in a company. With a company, all the habits, goals, vision and rituals are given to you in an employee handbook. The company is our coach, and in most cases, we listen and do as the coach says. Its easier to get things done in this environment.<p>In our personal lives, we gotta figure out our goals, work on our habits and setup rituals. We're also more flexible, more forgiving on when we want to do certain things and more rigid on the others. The Daily Planner is central to that ideology, working with one off and repeatable tasks . You onboard with your day first, could be as simple as calling your mum or going on a walk or do yoga. As you get more comfortable, you start to consciously build a life that you want to live by creating rituals and setting goals as you get more confident.<p>Personally, I haven't been able to get that through Todoist or Notion.
Show HN: Featurevisor – Git-based feature flags and experiments management
Why?<p>- Decouple application deployment from releases<p>How it works:<p>- Make changes to your features and segments (YAMLs) via Pull Requests
- Generate datafile (JSON file) in CI/CD workflow and upload to your CDN
- Fetch datafile in your application runtime and consume with SDKs<p>Supports:<p>- Feature flags: boolean flags
- Experimentation: a/b tests
- Segments: targeting traffic with conditions
- Variables: namespaced under each feature and conditional
- Gradual rollouts: avoid big bang releases, go from 0% to 100%
- Consistent bucketing: same user sees same variation
- Multiple environments: prod, staging, test, and more
- Force bucketing: allow testers to force enable/disable for themselves only
- Tagging: resulting in smaller datafiles for your application(s)
- Tracking: integration with any analytics tool
- Status site generator: for human friendly status reporting
- SDKs: for Node.js and browser environments, Kotlin/Swift planned for future

Show HN: Copilot for Data Analysis, beyond an open-source alternative to Tableau
RATH is an open-source software for data exploration and visualization. It automates your workflow in data analysis. You can give RATH a CSV file and it will generates visualizations with insights and patterns automatically. It also has a data painter tool for more casual interaction with charts (<a href="https://youtu.be/djqePNyhz7w" rel="nofollow">https://youtu.be/djqePNyhz7w</a>). It also has a lot of cool features like autovis, causal discovery, GPT integration, predictive interaction for text feature extraction, etc. Some of RATH’s components are also independent open-source project you might be interested:<p><pre><code> Like

Show HN: Homemade rocketship treehouse – hardware to custom OS
(This was previously submitted as <a href="https://news.ycombinator.com/item?id=2246856" rel="nofollow">https://news.ycombinator.com/item?id=2246856</a>)<p>The Ravenna Ultra-Low-Altitude Vehicle is a backyard rocketship treehouse nestled in the Seattle neighborhood of Ravenna. Click the link to see a demo video (<a href="http://rocket.jonh.net" rel="nofollow">http://rocket.jonh.net</a>).<p>The hexagonal treehouse is about 6.5 feet (2 meters) across at its widest point. The frame is welded mild steel with riveted aluminum siding. It contains nearly 800 LEDs forming dozens of numeric displays spread across 14 control panels, each with an acrylic face laser-cut and etched with labels such as "Lunar Distance" and "Hydraulic Pressure". The pilot controls the rocket using a joystick and panels full of working switches, knobs and buttons. Underneath the capsule are three "thrusters" that shoot plumes of water and compressed air under the control of the pilot's joystick, simulating real positioning thrusters. Takeoff and docking sequences are augmented by a paint-shaker that simulates the vibration of a rocket engine. Sound effects complete the illusion, with a powered subwoofer that gives the rocket a satisfying rumble.<p>When it was built in 2011, rocket operations were controlled by three Atmega328 microprocessors on custom-fabricated printed circuit boards, running a small operating system, RULOS, built just for this project. A trench running from the house to the rocket carries 12VDC power for the lighting and electronics, water for the thrusters, compressed air, and several data signals.<p>Since 2011, the two-person team has upgraded it, here is a recent update from the makers:<p>One of the most visible changes is replacing the primary 4-line display with a slicker 6-line display (i.e., 6 rows of 8 columns of 7-segment LEDs). The audio synthesizer has been upgraded to a PCB that can generate 50khz, 16-bit audio. The interconnection bus, which had been flat IDC cable carrying individual on/off lines, was upgraded to a true I2C-based networked distributed system with over a dozen individually addressable targets, all interconnected by standard cat5 cable that carries both our I2C protocol and power. We also moved much of the electronics from 8-bit atmega328s to newer, 32-bit STM32F3's. RULOS has been expanded into a pretty general purpose embedded systems platform ported to 5 major lines of CPU (atmega, attiny, stm32, nxp lpc, and esp32). We've used it for dozens of other projects in the last 12 years, including a nanosecond-accurate timestamper, a GPS datalogger, an air quality sensor, various little electronic control boards for toys (e.g. these, and this), and an autonomous boat (that sank). It is all available on Github: <a href="https://github.com/jelson/rulos">https://github.com/jelson/rulos</a>.
