Show HN: A modern CGI web framework for C++ https://ift.tt/Ljq9NtB

Show HN: A modern CGI web framework for C++ Hi, I work on this library because I like the simplicity of CGI and enjoy building things with C++. It is based on asio and my own implementation of FastCGI, and it works on both Linux and Windows. I have just released the new version and created a simple live demo that you can check out here: https://ift.tt/a6ST4ok https://ift.tt/mjyvaVW July 13, 2023 at 02:02AM

Show HN: GroceryTrip – Turn receipts into nutritional information https://ift.tt/XQkvCtf

Show HN: GroceryTrip – Turn receipts into nutritional information Hey HN, I've been working on a Flutter app for the past few months that turns receipts into useful nutrition information. The aim of this project is to make it easier to understand the nutrition and ingredients in our groceries simply by scanning a receipt. How GroceryTrip works (more detail in github repo): 1. Take a photo of your receipt (remains local, there's a demo receipt in the app if you don't have one on-hand) 2. Crop photo to relevant barcodes/names of products 3. View receipt Summary/Details 4. Optional: Contribute missing barcodes It's a super simple app currently, but I think it has potential to provide more insights into the food we purchase every week (viewing grocery trends over time may be useful). Any feedback or suggestions are appreciated! https://ift.tt/3QG5Wye https://ift.tt/3QG5Wye July 13, 2023 at 04:47AM

Innovation to Icon: 150 Years of Cable Cars Exhibit Opens

Innovation to Icon: 150 Years of Cable Cars Exhibit Opens
By Jeremy Menzies

We are happy to announce the opening of a special history exhibit at the San Francisco Public Library, as part of the ongoing celebrations for the 150th anniversary of the cable cars. The “Innovation to Icon: 150 Years of Cable Cars” exhibit runs from July 1 to September 30 on the 6th floor of the public library’s main branch library at 100 Larkin Street.

"Innovation to Icon: 150 Years of Cable Cars" takes a visual journey through time that brings the incredible history of San Francisco’s beloved cable cars to life. Combining photographs, original documents, and unique memorabilia from the San Francisco History Center and the SFMTA Photo Archive, this exhibit showcases the spirit, ingenuity and timeless allure of a city icon.

Invented in 1873 to conquer the city’s challenging topography, cable cars evolved from a groundbreaking transportation mode to a symbol of San Francisco. The cars have endured multiple boom-bust cycles, nearly becoming extinct more than once thanks to natural, political and economic turmoil. During the post-war era, they rose in popularity locally and nationally and became a “must-see” attraction for visitors.

Years of use and deferred maintenance in the 1970s left the system battered and unsafe. From 1982-1984, the entire system was shut down and rebuilt from the ground up. Reengineered for improved safety and structural integrity, the new system held onto its 19th century roots. 

Today, San Francisco’s cable cars are landmarks of American history and culture. Rather than being static relics from the past, they are living and moving museums, reminding us of what makes San Francisco such an extraordinary place. Drop by during regular library hours to immerse yourself in the world of the “little cable cars” that forever changed our city.
