Show HN: Bitcoin Challenge. Try to steal a plain text private key you can use Hi HN, I'm releasing my round one public demo of a new browser security system I've been developing. There's a real Bitcoin private key (worth $20) in plaintext at app.redactsure.com. You can copy it, paste it, delete it, move it around - full control. But you can't see the actual characters or extract them. The challenge: Break the protection and take the Bitcoin. First person wins, challenge ends. Details: - Requires email verification (prevents abuse, no account needed) - 15 minute time limit per session - Currently US only for the demo (latency) - Verify the Bitcoin is real: https://ift.tt/KGOow0q Technical approach: - Cloud-hosted browser with real time NER model - Webpages are unmodified - Think of it as selective invisibility for sensitive data. You can interact with it normally, just can't see or extract it Looking for feedback on edge cases in the hiding/protection algorithm. Happy to answer questions about the implementation. https://ift.tt/4JL8IhN August 25, 2025 at 11:16PM

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...
