Building a Mechanical Star Tracker for the ISS

Engineer Ted Kinsman was tasked by NASA astronaut Don Pettit to design and build a mechanical star tracker for capturing high-quality astrophotography images from the International Space Station (ISS). Due to the lengthy testing period for electronic devices, the tracker was entirely mechanical, cleverly utilizing a clock drive from an industrial oven. Gear ratios were adjusted to match the ISS's orbital speed. The device successfully reached the ISS in 2024 and has captured stunning images of the cosmos.

The Vanishing of Color: A Modern Aesthetic Shift

The Vanishing of Color: A Modern Aesthetic Shift

From cars and brands to film, grayscale and monochrome are dominating the world. This article explores the reasons behind this phenomenon, arguing it's not just about materials or fashion trends, but rooted in Western philosophy's long-standing devaluation of color. From Plato to Kant, reason was prioritized over senses, with color seen as sensory interference hindering the understanding of truth. Modernism further dismissed color as excessive ornamentation, pursuing pure form. However, the article argues this rejection of color ignores the harmonious unity of color and form, exemplified by the vibrant hues of Baroque art, where emotion and reason coexist. It's time to embrace color again, enriching our lives.

A Glimpse into the Future of Browser-Based Python: Introducing SPy

To overcome the speed limitations of Python in the browser, engineers from Anaconda and Cloudflare developed SPy. SPy isn't a simple Python port; it's a new language allowing a mix of compile-time and runtime code (blue and red code, respectively). Blue code, resembling Python, enables pre-computation at compile time, dramatically boosting performance. SPy code can be interpreted or compiled to C, then further compiled into native binaries or WebAssembly. A generative art demo showcased a 100x speed improvement by migrating from PyScript to SPy. While in early stages, SPy demonstrates impressive potential, promising near-Rust speeds for native Python execution in browsers in the future.

ESA's Fair Contribution Model: A New Approach to European Launchers

ESA's governance, hampered by a 'geo-return' policy linking member state investment to national benefits, has resulted in slow project approvals and cost overruns. The Ariane rocket program, heavily funded by France, exemplifies this. However, the rise of commercial spaceflight and smaller launchers challenges this model. ESA proposes a 'fair contribution' funding model, to be presented at the November ministerial conference. This model shifts funding responsibility to member states most benefiting from the successful launcher programs, aiming for greater efficiency and cost control in European space exploration.

While interning at Carnegie Mellon's Vision Science Labs, the author encountered challenges processing hyperspectral images. A graduate student described them as 'cubes' due to their structure: hundreds or thousands of matrices stacked together, resembling a 3D cube. However, at Specere Labs, researchers viewed them as groups of spectra from nearby regions. This highlights the differing perspectives across disciplines and the value of cross-disciplinary work.

Mars Dichotomy Boundary Eroded Hundreds of Kilometers

Mars Dichotomy Boundary Eroded Hundreds of Kilometers

New research suggests Mars' iconic dichotomy boundary, separating the higher southern hemisphere from the lower northern one, may have receded hundreds of kilometers due to water erosion. Researchers analyzed data from the Mars Express and Mars Reconnaissance Orbiter, finding that thousands of buttes and mesas near Mawrth Vallis, situated at the dichotomy boundary, share a similar height with a nearby higher-elevation plateau, indicating they are remnants of a larger plateau eroded away. This massive erosion suggests an active water cycle early in Mars' history, consistent with the theory of a northern ocean but also potentially caused by other hydrological processes like ice cap melting. The finding offers new clues about early Martian climate and geological evolution, adding to evidence for a past ocean but also raising new questions.

Calculating Reciprocal Throughput in LLVM's Scheduling Model

2025-03-30

This post delves into the calculation of reciprocal throughput within LLVM's instruction scheduling model. LLVM's scheduling model describes an instruction with three key properties: latency, hardware resources used, and the number of cycles it holds each resource. While the traditional approach uses the maximum release cycle to calculate reciprocal throughput, this breaks down when non-zero acquire cycles are present. By analyzing resource segments and the instruction scheduling process, the author derives a new method: using the length of the longest segment across all hardware resources as the reciprocal throughput. This addresses the shortcomings of the traditional method when dealing with resource segments, providing a more accurate basis for performance optimization in the LLVM compiler.
