Show HN: Don't Hold Your Breath – Breathing Analysis with Polar H10 HR Monitor A person's heart rate fluctuates based on factors such as activity, environment, and mental state. Additionally, heart rate variations occur on a much shorter timescale, with changes happening every few seconds. During inhalation, heart rate slightly increases, and it decreases again during exhalation, a phenomenon known as respiratory sinus arrhythmia. There are several reasons for this. Firstly, an increase in volume within the thoracic cavity (the space between the ribs) leads to a corresponding drop in pressure, which is counteracted by a rise in heart rate to regulate blood pressure. Secondly, breathing is deeply intertwined with the autonomic nervous system, which involves the opposing activation of the parasympathetic ("rest and digest") and sympathetic ("fight or flight") responses. By measuring heart rate variability and regulating our breath, we can gain insight into our stress response and learn to control it. The Polar H10 heart rate monitor provides basic heart rate measurements from a chest strap ECG, compatible with a number of fitness tracking apps that monitor heart rate zones wirelessly using bluetooth. The device also provides raw sensor data including an accurate measure of the timing between heartbeats (interbeat interval, with millisecond resolution) and 200 Hz accelerometer data. In this project this information is used to measure breathing rate and heart rate variability, and explore the relationship between the two. https://ift.tt/UtMJFVm April 15, 2023 at 12:36AM

Show HN: WikiBinge – discover how all things are vaguely connected (2016) Connect two articles on Wikipedia, but do it the long way. I've always been a fan of the theory of six degree of separation, but it's an overused concept when exploring the Wiki-graph. Instead of showing the shortest path, which in my opinion is "boring" and ends up connecting super-important central articles, I came up with my own method: WikiBinge selects the smaller, less represented articles on Wikipedia. In a WikiBinge path, the underdogs are the kings! How does it work? It's pretty straightforward! Compute PageRank on the Wiki-graph and assign as weight of each edge the PageRank value of the destination node. A WikiBinge path is then simply a shortest path using these weights: the algorithm will then favor paths passing through articles with lower PageRank values. More on the motives to build this here: https://ift.tt/nSFYLoT This is an older project of mine, but it never got much exposure, so I'm humbly submitting it now. https://ift.tt/xcrKAMF April 14, 2023 at 11:18PM

Show HN: Ampersand – “Terraform for Integrations” https://ift.tt/rSTYJtX

Show HN: Ampersand – “Terraform for Integrations” Hey HN! I’m one of the co-founders of Ampersand and we’re excited to launch our developer docs today! Ampersand is built for SaaS engineers who want to: - Read data from their customers’ SaaS (e.g. Salesforce, Hubspot). - Write data to their customers’ SaaS. - Subscribe to events happening in their customers’ SaaS (including creates, deletes and field updates). We feature a Terraform-like declarative interface for defining integrations, embeddable UI components for your users to set up and manage their integrations, and a management console for your team to monitor and troubleshoot. We’re launching our docs ahead of our product because we believe that docs are one of the most important things to get right in building a developer product, and we want to get early feedback on it. Looking forward to hearing your feedback in the comments below! https://ift.tt/zU05xdR April 14, 2023 at 02:38AM

Show HN: NeverPrinter – find and use thousands of nearby printers https://ift.tt/tSAF1xY

Show HN: NeverPrinter – find and use thousands of nearby printers Hi all, My friends and I have created a Chrome extension and we are looking for feedback on whether people find it useful or not. The extension is intended to serve as a home printer substitute for people (like us) who don't want or need their own printer at home. It makes it easy to send documents to nearby office supply / shipping stores for printing and pickup. Installing the extension adds a printer named NeverPrinter to your list of available printers in Chrome. When you print a document with NeverPrinter, a new tab opens allowing you to select which nearby store you want to send the document to. This is the latest iteration in an ongoing project my friends and I have been working on. We would love to hear any positive or negative feedback. You can get the extension by going to the Chrome Web Store and searching for "NeverPrinter." Or you can visit https://ift.tt/6KJ2yaM , which will redirect you there. https://ift.tt/GIWNXuM April 13, 2023 at 11:18PM
