We Built a GPS-Guided, Wire-Free Robot Mower for Large Lawnshttps://news.ycombinator.com/item?id=45914061Hi HN,I’m Noor, part of the product team at Yarbo, where we’re building modular outdoor robots that handle lawn care, snow removal, and yard maintenance all using the same autonomous drive base.We recently finished a full-season field test of our wire-free, GPS-guided robot mower, and wanted to share what we’ve built, the technology behind it, and what we learned from real users maintaining large lawns.The Real Problem We Wanted to Solve Almost every robot mower on the market still depends on buried perimeter wires.For homeowners with large or complex lawns (½ acre and up), those wires are frustrating — they take hours to install, frequently break, and make even small landscaping changes painful.We saw this problem repeatedly in user feedback: “The mower works fine until a wire gets nicked — then I have to dig up half my lawn to find the break.”We wanted to remove wires entirely while keeping centimeter-level accuracy and full autonomy. That meant solving for GPS drift, multi-zone mapp

Show HN: Qantify – GPU-Accelerated Trading Library with Advanced Math and AutoMLhttps://github.com/Alradyin/qantifyI've been building Qantify for the past 2 years - an open-source Python library for algorithmic trading that combines institutional-grade math models with modern ML/AutoML pipelines.*What makes it different:*Most trading libraries are either: - Too slow (Backtrader: ~5ms/point, Zipline: ~10ms/point) - Missing advanced math (no quantum finance, chaos theory, optimal execution models) - No AutoML pipeline (QuantConnect has basic ML but no AutoML) - No GPU accelerationQantify addresses all of these.*Performance:* - 0.008ms per data point (50-100x faster than alternatives) - GPU acceleration: 2-3x speedup on compatible hardware - 1767+ comprehensive tests, 100% code coverage - 106K+ lines of code*Advanced Math Models* (what hedge funds use):on # GARCH volatility modeling from qantify.math.econometrics import GARCHModel garch = GARCHModel(returns) vol_forecast = garch.forecast(horizon=10)# Heston stochastic volatility from qantify.math.stochastic import HestonProcess, MonteCarloEngine hesto

Ask HN: Help me understand Signal communication blurbhttps://news.ycombinator.com/item?id=45909780at bottom of signal communication on cellebrite [0] it states :>The completely unrelated>In completely unrelated news, upcoming versions of Signal will be periodically fetching files to place in app storage. These files are never used for anything inside Signal and never interact with Signal software or data, but they look nice, and aesthetics are important in software. Files will only be returned for accounts that have been active installs for some time already, and only probabilistically in low percentages based on phone number sharding. We have a few different versions of files that we think are aesthetically pleasing, and will iterate through those slowly over time. There is no other significance to these files.can someone help me understand if this is serious or not and what it actually means?[0] https://signal.org/blog/cellebrite-vulnerabilities/

Ask HN: How would you set up a child’s first Linux computer?https://news.ycombinator.com/item?id=45864732As a tech parent I think one of the best things I did for both my son and daughter was for their first computer to help them to build and setup their own Linux computer (It was Ubuntu back then but they’ve both moved themselves to Arch these days).We went together and bought a second hand desktop (exciting the people selling to us also) and when I got home I pulled out the Ram, HD and CD drive and set them aside; and then together with a screwdriver we “built the computer” over a few days.In windows when a child goes searching the web for a “movie maker for windows” they are going to be in a world of hurt either finding expensive commercial options or super scammy sites promising the world.By comparison on Linux if they search the local “app store” they’ll find stacks and stacks of free, useful, open licensed software.My kids loved the power, freedom and later unexpected community this bought them.Now my friend wants the same for their daughter who is 8 years old.I’m planning to do the
