Foreclosure is very bad for both the bank and the operator, so both parties would rather “extend and pretend,” leaving the building vacant while they wait and hope for the market to change. ]]> via:hn finance money real-estate buildings commercial-property dereliction empty-buildings vacancy extend-and-pretend loans foreclosure https://pinboard.in/ https://pinboard.in/u:jm/b:0751972cafe0/ 2026-04-27T08:45:23+00:00 https://www.jeffgeerling.com/blog/2026/new-10-gbe-usb-adapters-cooler-smaller-cheaper/ jm ethernet usb networking hardware via:hn reviews 10gbe https://pinboard.in/ https://pinboard.in/u:jm/b:14e53f7877ac/ 2026-03-20T10:05:04+00:00 https://news.ycombinator.com/item?id=47446571 jmWhen I visited LA, I rode in a Waymo going the speed limit in the right lane on a very busy street. The Waymo approached an intersection where it had the right of way, when suddenly a car ignored its stop sign and drove into the road. In less than a second, the Waymo moved into the left lane and kept going. I didn't even realize what was happening until after it was over. Most human drivers would've t-boned the car at 50+ km/h. Maybe they would've braked and reduced the impact, which would be the right move. A human swerving probably would've overshot into oncoming traffic. Only a robot could've safely swerved into another lane and avoid the crash entirely. Unfortunately, the Waymo only supported Spotify and did not work with my YouTube Music subscription, so I was listening to an advertisement at the time of my near-death experience. 4.5 stars overall. ]]> waymo funny anecdotes safety driving ai roads spotify via:hn https://pinboard.in/ https://pinboard.in/u:jm/b:aa371d8e3930/ 2025-11-20T10:05:40+00:00 https://amenzwa.github.io/stem/ComputingHistory/HowSlideRulesWork/ jm science maths slide-rules computing history antiques via:hn https://pinboard.in/ https://pinboard.in/u:jm/b:18f6e7086fdd/ 2025-06-18T09:45:43+00:00 https://cardstock.run/ jm education python web coding apps hypercard via:hn https://pinboard.in/ https://pinboard.in/u:jm/b:53ac6c47de56/ 2025-06-18T09:44:50+00:00 https://pontus.granstrom.me/scrappy/ jmThe apps we use are almost exclusively mass-market, sold on an app-store, made for thousands if not millions of users. Or they are enterprise apps that are custom-built for hundreds of thousands of dollars. But there isn’t really any equivalent of home-made software — apps made lovingly by you for your friends and family. Apps that aren’t polished or flashy, but are made to your preference and help you with your particular needs. [...] We ended up creating a research prototype that we call Scrappy — a tool for making scrappy apps for just you and your friends. First and foremost, we aim to contribute a vision of what home-made software could be like. We want to make this vision as concrete as we can, by sharing a working tool and examples of apps made in it. Scrappy, in its current state, is a prototype, not a robust tool, but we hope it paints the picture we carry in our heads — of software as something that can be creative, personal, expressive. Made by anyone, for themselves and their loved ones.

Gox experience this issue? They run a custom Bitcoin daemon, with a custom implementation of the Bitcoin protocol. Their implementation, against all advice, does rely on the transaction ID, which makes this attack possible. They have actually been warned about it months ago by gmaxwell, and have apparently decided to ignore this warning. In other words, this is not a vulnerability in the Bitcoin protocol, but an implementation error in Mt. Gox' custom Bitcoin software.
