Show HN: Grab a Random ArXiv Paper https://ift.tt/I1uK7d0

Show HN: Grab a Random ArXiv Paper I needed a way to grab a random paper from arXiv, so I built one and wanted to share it with you. It 1) picks a random topic (of all the cs. , econ. , math.* etc. topics) 2) finds the maximum amount of papers in that topic, and 3) queries for a random paper in that topic. Note that this skews the distribution heavily in favor of topics that are less common, but it should get the job done. Suggestions for improvements are welcome. https://ift.tt/xncuhms June 5, 2025 at 11:13PM

Show HN: This database never puts you on hold Hey everyone! I hope you’re all having a great day. Today I’m sharing an experimental open-source project I’ve been working on for the past few months called Wildcat. Wildcat is an embedded persistent storage engine implementing an lsm tree similar to RocksDB and or LevelDB. The motivation for this system was to try to solve the multi-writer bottlenecks that most embedded systems incur. With that, during my journey with storage systems especially the log structured flavour I’ve implemented a lot of interesting optimizations and algorithms in regards to the write and read paths. I hope you check it out :) Alex https://ift.tt/3Hv4N1u June 5, 2025 at 11:02PM

Show HN: Smart Palette – Reimagining AI Art https://ift.tt/XEQWf0O

Show HN: Smart Palette – Reimagining AI Art Hi HN, I'm Nick. Over the last 6 months I’ve been building Smart Palette – a platform to help anyone create unique, wall-ready art without needing to be a prompt expert. I started this because I wanted to unleash creativity in anyone and help them bring their art ideas onto their wall through a simple, guided and inspiring process. Instead of figuring out the “right” words to use, you just select your interior design style, room, art style, theme, and color palette. You can simply describe what you want to see and add your desired colors — or let Smart Palette handle it for you. Smart Palette uses a streamlined UI that my backend then translates into optimized, detailed prompts. A lot of the work went into this "translation" layer to ensure optimal model selection, settings and generation techniques depending on the user’s creative context. It also has a full print-on-demand (UHD) integration including various cusotmization options and an art preview feature. This is an early version, and I'd be very grateful for any feedback you have on the concept, the UX, or any technical aspects. Happy to answer any questions! You can try it out with a free trial and generate your first artwork. Here’s a quick walkthrough: https://ift.tt/z4RtanX?... https://ift.tt/GWwYCDf June 5, 2025 at 12:58AM

Making it Easier to Find and Pay for Parking: Behind Our Work to Upgrade Nearly 27,000 Meters

Making it Easier to Find and Pay for Parking: Behind Our Work to Upgrade Nearly 27,000 Meters
By Pamela Johnson

SFMTA crews replaced thousands of meters across the city with new ones that are easier to use. We recently finished upgrading every single parking meter in San Francisco – covering about 26,700 spaces -- to make it easier for you to park your car anywhere in the city. The new meters we installed through our Citywide Parking Meter Replacement Project: Make it easier to understand requirements and choose a payment option. Meters now have larger, brighter screens with more legible text and an intuitive user interface. Support customers who speak languages other than English. Meters now offer the...
