IPv6's Failure: A 30-Year Retrospective

2025-03-21

This article reflects on the 30-year journey of IPv6, from its initial design principles to its current practical applications, delving into the reasons why IPv6 failed to replace IPv4. The author points out that IPv6, in its initial design to simplify the transition, added new features that led to complexity. For example, extension headers are difficult to parse, and the multi-addressing mechanism has increased the difficulty of implementation and deployment. The author argues that there were key mistakes in the IPv6 design, such as the use of 128-bit addresses, inclusion of fragmentation handling and extension headers. Ultimately, these problems led to IPv6 deployment and adoption being far lower than expected, and in some ways inferior to IPv4.

NULL Pointer Dereferences on macOS Apple Silicon: Exploitable No More?

This article explores why NULL pointer dereference vulnerabilities are no longer exploitable for privilege escalation on Apple Silicon (ARM64) macOS. Historically, attackers manipulated memory mapping (especially in 32-bit systems) to exploit these bugs for code execution. However, macOS has significantly improved its security over the years. Hardware mitigations like SMEP, PAN, and PXN, along with Pointer Authentication Codes (PAC), the removal of 32-bit support, and enhanced kernel memory management make such exploits incredibly difficult, if not impossible. On modern macOS, NULL pointer dereferences primarily result in Denial of Service (DoS), not privilege escalation. The article details these improvements and provides a checklist for researchers before reporting such vulnerabilities.

The Rise of Solar PV: A Cheap Energy Future?

This article explores the rapid growth of solar photovoltaic (PV) power generation and its future potential. While currently accounting for only around 4% of total US electricity generation, the cost of solar PV has fallen nearly ten thousandfold in the last 70 years and is projected to fall further. However, the intermittency of solar power is a major challenge, as it cannot generate electricity on demand. The article uses simulations to explore strategies for addressing intermittency by increasing solar panel capacity and energy storage systems. It concludes that as solar and storage costs continue to decline, "overbuilding" to meet a larger fraction of electricity demand will become economically feasible. Ultimately, solar's low and declining costs make it a competitive energy option, but its intermittency remains a challenge to overcome.
