Show HN: Maps for e-scooters (hills and battery routing) I built BattMap, AMA! Living in San Francisco is hilly. Google Maps is great for bike maps, but I wanted to know if my scooter could make it up the hills, how much battery it would burn, and if I could make it back home without recharging it. https://battmap.com July 8, 2026 at 06:06AM

Show HN: PostgreSQL performance and cost across 23 EC2 instance types https://ift.tt/Cpqj4rX

Show HN: PostgreSQL performance and cost across 23 EC2 instance types Hey! I'm Andrei. I got frustrated by how people tend to build overcomplicated backend systems, being "motivated" by big tech case studies and popular books. So, I started exploring lean architecture, and building my digital garden of ideas, approaches and data that align with this direction. Here I want to present one of the tools – Sizing tool for PostgreSQL. I've benchmarked PostgreSQL on different EC2 instances and disks, with different initial data sets to see performance that these instances can give you. And I've built a tool to visualize this data, which I welcome you to explore. So, you can put your usual input parameters, like needed RPS and disk size as input, and find out which instance will be the most cost-efficient for your needs. You can read about the methodology here: https://ift.tt/7fr5uig I've tested one workload – mixed 90/10 read/write, and only selected configurations. But it is extensible, and I (and you – benchmark is open source: https://ift.tt/xMHh5Vf ) can run more configurations to have more data represented. Does it look interesting? What workload should I benchmark next? https://ift.tt/uqdnhV2 July 7, 2026 at 02:40AM
