Show HN: In-depth photographic look at all the golf courses I play https://bit.ly/3ndrsLG

Show HN: In-depth photographic look at all the golf courses I play I'm an avid golfer; it's my main hobby. I decided to start taking pictures of all the courses I play. While there's a lot of golf websites out there, none of them really try to document the courses in depth and look at each hole, along with the course facilities like the practice areas. I live in Chicago and am starting with the courses in this area (of which there are dozens of public courses to play). While I play golf, I take photos with my phone of every (relevant) aspect of the golf course I can think of. Then they're processed and organized on the website. Obviously I'm starting this journey on my own, and in that sense it's not scalable. I won't be able to visit all the courses in the US, let alone the world. I hope to find others that would like to contribute to the effort. At some point I'd like to add course news and histories to the site. Many golf courses in the US are over 100 years old and have rich histories. And of course many older courses exist in Europe. I also have started adding descriptions/commentary for each hole on courses. For example, see: https://bit.ly/3HP7TCV... And maybe went a little overboard on this one: https://bit.ly/3HNiU7K... Anyway, it's a fun project and could go in a lot of directions. PS: I'm always looking to expand my golfing circle. If you're in Chicago and want to play sometime, hit me up -- contact details are on the website. https://bit.ly/3boX528 June 23, 2022 at 08:53PM

Show HN: Pragmatic Formal Modeling (Tutorial series with runnable examples) https://bit.ly/3Om28PO

Show HN: Pragmatic Formal Modeling (Tutorial series with runnable examples) Formal modeling is a mathematical approach for designing and checking correctness of software systems. It focuses on standard software engineering and distributed systems problems of the sort programmers face every day. It takes a pragmatic engineering approach: each problem starts with UML diagrams, design decisions and sometimes even a requirements document. We work through how to get from a whiteboard design to an initial mathematical model. Then we refine it based on logical errors found by the model checker, which return with a level of detail unheard of in a standard debugger. Formal modeling is a skill every engineer should have in their toolbox. All the examples are downloadable, and their is a quick setup section at the start. Additionally, there is an explorable model error debugger build right into the website. https://bit.ly/3Oq15hg June 22, 2022 at 06:43PM

Show HN: PyCircTools – A Python library to create circuits https://bit.ly/3yaQq4J

Show HN: PyCircTools – A Python library to create circuits PyCircTools is a python library that allows any programmer to create circuits with it. It is currently a work in progress and as for today, v0.0.3 is the most recent release. It just has logic gates, custom exceptions and tests for now, but the library will be updated with more content, so check back on it back to see new additions! https://bit.ly/3zPWaCd June 21, 2022 at 10:41PM

Show HN: Free Datasets for Spatial Engineers and Location Analysts https://bit.ly/3bcqmgy

Show HN: Free Datasets for Spatial Engineers and Location Analysts location data providers are often in the press with negative headlines. Those services aggregate movement data from apps and aggregate the data to derive movement patterns which might be helpful for marketers. In fact, I had two moments in my life where I evaluated a PoC with those location data brokers. They were all shady about where the data comes from which is important to understand the Bias of the data. I never got a good answer. The data often just represented < 0.4% of the population (at least in Europe - different game in the USA). For a big city they might have 20K unique users while in the city were more than 3M users living. They dismiss any professional data analytics principle. The data comes in CSV (if a lot of data they give you like 10 separate files). Data was not always plausible in itself Those experiences brought me to build certain parts of those data brokers but only with open-source data: If it is about location data you should know OpenStreetMap. It's the biggest Database with meta info on location. It's not perfect but big companies like Mapbox, Apple, and Microsoft rely on it. Since the API is kind of messy, you can load with this repository whole cities information smoothly into a PostGres --> https://bit.ly/3Oc12Ga Googe Popular Times: Movement data can be also found on Google. When you search a location it is often shown how frequently a place was visited on an hourly-daily basis (on an index of 0-100). With this libary you can access all the Popular Times data for location and entire cities --> https://bit.ly/3tRVdWh Global Admin Boundaries: A huge problem that often people feel when working with location data is aggregating the data into different geo-based slices (country level, admin level, or even smaller into sub-districts). Here is a repo that cleaned the data out of Open Street Map for geo boundaries worldwide from very broad to a very small granularity --> https://bit.ly/3OrE0uz I think with those Open Source Tools and some data science magic you can generate similar outcomes as those location data providers but totally anonymized and free. Would be awesome if anybody is interested in building a case around it :-) June 21, 2022 at 12:35PM
