Flight Tracking's Dirty Little Secrets: Debunking Aviation Data Myths

FlightAware engineers discovered that aviation data is far messier than one might assume. They list numerous false assumptions about flights, airports, airlines, and ADS-B data – things like flights always departing on time, flight numbers never changing, and airport information always being accurate. The breakdown of these assumptions highlights the challenges and importance of FlightAware's flight tracking engine, Hyperfeed, in handling unusual situations and providing a consistent data feed.

Pluto's Largest Moon, Charon, Formed Via a 'Kiss and Capture' Event

2025-01-20

Pluto's Largest Moon, Charon, Formed Via a 'Kiss and Capture' Event

A new study proposes a novel 'kiss and capture' mechanism for the formation of Charon, Pluto's largest moon, challenging the previous catastrophic impact theory. Billions of years ago, Pluto and Charon collided in the outer solar system, briefly merging into a spinning dumbbell shape before separating, yet remaining gravitationally bound. This collision didn't destroy either body, preserving their structural integrity. The theory, incorporating the strength of Pluto and Charon's materials, was validated by computer simulations, accurately predicting the current binary system's orbit. This discovery challenges conventional understanding of planetary collisions and offers a new perspective on the formation of other binary systems.

Universities Must Resist the AI Onslaught

2025-06-23

A seminar at Goldsmiths Centre for Philosophy and Critical Thought explored AI's impact on higher education. The speaker argued that AI isn't futuristic sci-fi, but a product of neoliberal education systems. AI's operation relies on massive data and computing power, its inner workings opaque and unpredictable. The speaker called for universities to resist AI's overreach, impacting not just academic integrity but critical thinking and social equity. He advocated using Ivan Illich's concept of 'convivial tools' to critically examine AI and establish workers'/people's councils to ensure technological social determination, preventing AI from becoming a tool of control and oppression.

Pentagon Halts Army Contracts, Sending Shockwaves Through Defense Industry

A freeze on new US Army contracts has thrown the defense industry into chaos and uncertainty. The move, stemming from a review of plans implemented under the Trump administration, lacks clear explanation regarding its scope and reasons. While the Army spokesperson claims contracting activities continue, internal documents and sources indicate a pause or review of all contracting actions except those directly tied to readiness, modernization, and personnel. The communication, delivered via email rather than formal memo, has left program managers confused about implementation. Industry fears this could be the start of a Pentagon-wide freeze, creating widespread anxiety about future projects.

Go Protobuf's New Opaque API Improves Performance and Safety

2024-12-16

The Go team released a new Opaque API for Go Protobuf, coexisting with the existing Open Struct API. This new API decouples generated code from its underlying memory representation, leading to performance improvements, reduced memory allocations, and enabling optimizations like lazy decoding. By hiding struct fields and accessing them only through accessor methods, it prevents pointer-related bugs and accidental sharing. Migration involves enabling the Hybrid API, using the `open2opaque` tool, and then switching to the Opaque API. The existing Open Struct API remains supported.

Zig: Safer and Faster Than Unsafe Rust?

This blog post compares Rust and Zig by implementing a garbage-collected bytecode interpreter. The author found unsafe Rust incredibly challenging, citing complex aliasing rules and undefined behavior as major obstacles. In contrast, Zig offered a more developer-friendly experience for memory-unsafe operations, including built-in memory leak detection and improved pointer ergonomics. The Zig implementation ultimately proved safer, faster, and easier to develop than its Rust counterpart.

Volvo Recalls 7,483 PHEVs Due to Fire Risk

Volvo is recalling 7,483 plug-in hybrid vehicles in the US due to a potential fire hazard. Affected models include the S60, V60, S90, V90, XC60, and XC90. The issue stems from a battery module production deviation that could cause a short circuit and thermal runaway. Owners are urged to stop charging their vehicles until the recall is addressed. Dealers will inspect and replace the battery module if necessary, and install new monitoring software. While two incidents have been reported, no injuries or accidents have occurred.

UK MPs Question Fujitsu's Continued Bidding for Government Contracts Amidst Horizon Scandal

Despite a previous pledge to halt bidding for UK public sector contracts following the Post Office Horizon scandal, Fujitsu continues to pursue large-scale IT projects, sparking outrage among British MPs and peers. The scandal involved a faulty computer system supplied by Fujitsu that led to the wrongful conviction of hundreds of subpostmasters. While Fujitsu claims to only bid when directly invited, it won a £125 million contract and continues bidding for others, including the £370 million Trader Support Service (TSS). Parliamentarians are concerned about Fujitsu's continued involvement while compensation for victims remains unresolved, questioning the government's assessment and the potential reputational damage.

A 1987 Computer Language article detailed Microsoft's then-new OS/2, predicting its potential to dominate Intel 80286/80386 microcomputers for the next decade. Its multitasking, comprehensive API, and hardware extensibility were highlighted as key strengths. OS/2's architecture featured three layers: the kernel and system services, the Windows Presentation Manager (WPM), and the OS/2 LAN Manager. The article focused on the kernel and its system services, covering process management, memory management (including virtual memory), device drivers, file management, and inter-process communication (IPC). OS/2 used preemptive scheduling and time slicing, supported protected and real modes, and offered MS-DOS compatibility. Dynamic linking was a crucial element, enhancing code reuse and future-proofing applications. The article concluded by speculating on OS/2's future enhancements and 80386 support.

CSS Layouts: A Critical Analysis

2025-08-06

This article offers a critical analysis of CSS layout mechanisms. The author argues that CSS conflates rich text styling and the layout system, leading to inconsistent inheritance—text styles inherit, but layout properties don't. Nested inline-block and inline-flex models exemplify this conflict: internally they're block or flex, externally they're inline. The author proposes that an ideal layout system would decompose behavior into independent facets, offering a more flexible and intuitive API than the current subtractive one with extra containment barrier hints. Finally, the article touches upon the limitations of relative em scaling and improvements in pixel handling.

Understanding Cell-Based Architectures Through a Zombie Apocalypse

This article uses a vivid zombie siege scenario to explain cell-based architectures. The author likens a city to a system, with each neighborhood acting as an independent 'cell'. Even if one neighborhood falls, the entire city doesn't collapse. This isolation strategy, mirroring the design principles of cell-based architectures, effectively reduces the impact of single points of failure, ensuring system stability. Through this analogy, the article clearly explains the advantages and importance of cell-based architectures.

Pentagon Purges DEI Content: Historical Photos Among Thousands Flagged for Removal

The Department of Defense is undertaking a massive purge of diversity, equity, and inclusion (DEI) content from its websites and social media, targeting over 26,000 images. This includes photos of a World War II Medal of Honor recipient, the Enola Gay, and the first women to graduate from Marine infantry training. The action stems from President Trump's executive order ending DEI programs across the federal government. The purge has led to confusion, with images containing the word "gay" mistakenly flagged for removal, impacting both individuals with that surname and the aircraft itself. Historically significant photos, such as those of the Tuskegee Airmen, may be spared. The Pentagon claims it's working to comply rapidly, but the process is proving time-consuming and complex.
