RISC vs Dandelion

RISC-V Assembly Simulator is a mobile 32-bit system simulator. The app simulates the entire system, all the way from each individual unit on a CPU to the memory subsystem. Write assembly natively to the CPU, with a built-in debugger so you can analyze your code and see what the hardware is doing. This app is designed to allow you to learn how to write assembly from your mobile device, simulating a real CPU at your devices maximum speed. Visualize how the hardware works if you want to, see all the registers, see your entire memory subsystem for each cycle. Learn the components of this individual CPU. This app currently supports the base Int for RV32 along with the M extension, allowing multiplication and division. Dual core systems are supported with the atomic instructions. This app features a built in assembler to allow you to learn to write code along with descriptive errors. Code along with Apple Intelligence, giving you advice and helping you fix bugs along the way (experimental). Natively integrated with your devices file system, allowing seamless transfer between devices and potentially other sources.

A star cluster in the Galaxy's tidal field is a dandelion clock: two-body encounters slowly hand stars enough energy to drift past the Jacobi radius, where the Milky Way's tide plucks them away into two long tails of seeds. Dandelion integrates this process on your device's GPU: a real, self-gravitating direct N-body simulation with the Galaxy's tidal field, stellar evolution, and tidal tails followed to kiloparsec distances. For the open-cluster presets, every point of light is one star. WHAT'S REAL - King, Plummer and EFF initial models, sampled from their distribution functions - Kroupa and Salpeter initial mass functions - Two-body relaxation, mass segregation, evaporation - The exact differential Galactic tide, with no linearized approximation - Stellar evolution: main-sequence lifetimes, red giants, white dwarfs, kicked neutron stars, black holes WHAT'S NOT - No binaries and no few-body regularization - No molecular clouds, spiral arms or bar: real clusters near the Sun dissolve 3 to 5 times faster than the smooth tide alone The app admits its limits where they matter, in plain sight. THIRTEEN CLUSTERS FROM THE LITERATURE Adopt the Hyades, the Pleiades, Praesepe, a scaled Pal 5 stream and nine more, each recreated from published parameters. Or build your own cluster and read an honest prognosis, relaxation time, Jacobi radius, dissolution estimate, before you release it to the wind. WATCH, MEASURE, RIDE ALONG Fly through the cluster as it evolves at up to 20 million years per second. Reverse time. Track bound mass, radii, velocity dispersion and tail growth in seven live charts. Tap a star to see its mass, speed and fate, and ride along as the tide carries it down the tail. Share any cluster as a link: same seed, same stars, on any device. No accounts, no ads, no data collection.
