Show HN: FastQR – A Fast QRCode Generator Supporting Batch Processing https://ift.tt/VxUSjKe

Show HN: FastQR – A Fast QRCode Generator Supporting Batch Processing I'd like to share FastQR ( https://ift.tt/2Q0V4vO ), a high-performance QR code generator written in C++. This is my first open-source project, and I'm excited (and a bit nervous!) to share it with you all. What it is: - A fast CLI tool and library for generating QR codes - Written in C++ with bindings for Ruby, PHP, and Node.js - Full UTF-8 support (works great with Vietnamese, Japanese, and other languages) - Supports custom colors, logo embedding, and precise size control - Pre-built binaries included – no need to install dependencies separately Why I built this: - I needed a QR code generator that was fast, supported UTF-8 properly (especially for Vietnamese text), and could be easily integrated into different languages. Most existing solutions were either slow or had poor Unicode support. Performance: - Generating 1000 QR codes (500x500px): ~0.37 seconds Tech stack: - C++ core using libqrencode and libpng - Language bindings for Ruby, PHP, and Node.js - Precompiled binaries for easy installation This is my very first open-source project, so I'm sure there are things that could be improved or bugs I haven't caught yet. I'd really appreciate it if you could try it out and share your feedback. If you find any issues or have suggestions, please open an issue on GitHub – I'll do my best to fix them quickly. Any feedback, criticism, or suggestions would be greatly appreciated. Thanks for taking the time to check it out! GitHub: https://ift.tt/2Q0V4vO October 21, 2025 at 10:59PM

Twin Peaks for All: Survey Results By Benjamin Barnett Last month, the SFMTA and San Francisco Recreation and Parks Department released a survey seeking public feedback regarding  five proposed roadway options for Twin Peaks Boulevard . San Franciscans responded to the survey, ranked support for each alternative and shared opinions about how the different options met their needs.  The Twin Peaks for All survey was open for almost three weeks and received more than 1,700 responses. This number reflects the high level of interest for this San Francisco park and its future access.   Survey Background Conditions on Twin Peaks Boulevard between Portola Drive and Barnett Avenue before COVID street closures.   The Twin Peaks Boulevard gates were closed early in the pandemic to reduce crowding at the lookout point parking lot. The gates were closed on the north, at Burnett Avenue, and the south, at Portola Drive. Since then, Twin Peaks Park use by hikers, joggers and peopl...

History in Motion: New Photos from the 1960s to 1980s Now Online

History in Motion: New Photos from the 1960s to 1980s Now Online By Jeremy Menzies We’ve been hard at work in the SFMTA Photo Archive and recently uploaded two large collections of photos from the early 1960s to the 1980s to our website. These photos, both color and black and white, give a glimpse into the day-to-day operations of Muni and the streets of San Francisco. Here’s a selection of shots from this brand-new batch of photos, many of which have not been seen outside the Photo Archive in years.  This shot shows a typical evening rush hour scene from the mid-1970s taken at Market and Powell Streets.  The color photos from this era are all part of a collection that was most likely used for presentations, studies and as general “stock” type photos of San Francisco, streets and Muni facilities and operations. Subjects include project documentation, copies of maps and charts, street...
