Infernal Views: Reconstructing the Venera Images of Venus

Only four spacecraft have ever returned images from Venus's surface. The planet's extreme heat and pressure quickly destroy landers, making exploration incredibly challenging. In 1975 and 1982, the Soviet Union's Venera probes captured the only images we have of Venus's surface. These images, painstakingly reconstructed by Ted Stryk using data from the Russian Academy of Sciences, reveal a desolate landscape of cracked ground under yellow skies—a world that may once have resembled Earth before a catastrophic climate shift.

Supreme Court Unanimously Orders Return of Wrongfully Deported Salvadoran Migrant

The Supreme Court unanimously ruled to return Kilmar Abrego Garcia, a Salvadoran migrant wrongfully deported to El Salvador. The case highlights the administration's disregard for due process in deportation proceedings and the court's determination to check executive overreach. While the Court's opinion was cautiously worded, the justices broadly condemned the administration's actions, setting a precedent for future cases. The case also reveals a secretive agreement between the US and El Salvadoran governments involving the deportation of gang members, the details of which remain unclear. The ultimate outcome hinges on the lower court's enforcement of the Supreme Court's ruling and whether the administration complies with the order to return Abrego Garcia.

Chang'e 6 Finds Moon's Far Side Surprisingly Dry

Analysis of lunar samples returned by China's Chang'e 6 mission suggests the far side of the moon may be drier than the near side. Scientists examined 578 particles from the South Pole-Aitken basin, estimating water abundance at less than 1.5 micrograms per gram—lower than previous near-side findings. While more samples are needed for conclusive evidence, the dryness could be linked to the basin's formation or variations in water distribution. This finding is unlikely to significantly alter NASA's plans to land astronauts near the lunar south pole, where abundant water ice is expected to support future missions.

Procedurally Generating Forest Creatures: A Long and Challenging Journey

The author spent years working on procedurally generating and animating a large number of forest creatures for their game, The Big Forest. Initially, they tried using simple parametric models, but the results were unsatisfactory. They then shifted to manual parameterization and used Principal Component Analysis to find higher-level parameters, but the results were still not ideal. Ultimately, they abandoned automated solutions and instead manually defined higher-level parameters, developing tools to assist in parameter adjustment. For animation, the author built upon previous research, using a kinematic approach and continuously refining it to achieve more natural creature movement. The entire process was challenging but also enjoyable, and the author shares their experiences of trial, error, and improvement.

Sentient: Grappling with Infinity in Constraint Solvers

This article delves into the challenges of handling infinity within the Sentient constraint solver. Sentient, a programming language, tackles constraint satisfaction problems by translating them into Boolean equations. Because integers in computers are represented with a finite number of bits, Sentient can't directly handle mathematically infinite integers. The author proposes an approximation-based solution, incrementally increasing the bit size of integers to approximate the infinite space. The article discusses leveraging the incremental SAT solver IPASIR for efficiency, avoiding redundant searches. It also explores extending this approach to more complex scenarios, such as handling arrays and optimization problems, ultimately touching on the possibility of Sentient achieving Turing completeness in the future.

VM Cloning and Linux Random Number Generation: Security Implications and Solutions

This document analyzes the security implications of restoring multiple VM clones from a single snapshot. Linux exposes three main RNG interfaces: /dev/random, /dev/urandom, and the getrandom syscall. Cloning VMs leads to inconsistent RNG states due to multiple parameters (like timer data or CPU HWRNG instruction outputs) being mixed into each result. The article examines different implementations of RNGs in newer and older kernels and proposes solutions: reinitializing the RNG after restore, using the virtio-rng device, and leveraging the VMGenID mechanism (introduced in Linux 5.18 and later) to address inconsistent RNG states after cloning.

Ancient DNA Reveals Isolated Saharan Population 7,000 Years Ago

A new genetic analysis sheds light on the genetic makeup of humans living in the Sahara's green oasis 7,000 years ago. Researchers sequenced ancient DNA from two women buried at the Takarkori rock shelter in Libya, finding their closest genetic relatives were 15,000-year-old foragers from Morocco. This suggests a long-standing, stable population in North Africa before and during the Saharan humid period. This lineage diverged from those leaving Africa over 50,000 years ago and remained largely isolated for millennia, with only minor gene flow from the Levant, including Neanderthal DNA. The study suggests pastoralism spread through cultural exchange, not large-scale migration.

Stop Explaining e with Compound Interest

2025-04-11

Math classes often introduce the natural constant *e* using compound interest: a 100% annual interest account doubles with yearly compounding, becomes 2.25 times with semi-annual compounding, approximately 2.714 times with daily compounding, and exactly *e* times with continuous compounding. However, this is misleading. Compound growth is exponential, but the example uses linear division of compounding periods. Banks must separately publish the interest rate, compounding interval, and annual percentage yield. There are far more elegant ways to introduce *e*, such as its unique property of being its own derivative, or its crucial role in Euler's formula. These approaches don't require prior knowledge of *e* and are mathematically more rigorous.
