The Green Fairy's Fall: Absinthe From Muse to Moral Panic

2024-12-16

In late 19th-century France, absinthe, once celebrated as the 'Green Fairy' and muse to artists and poets, fell from grace due to its high alcohol content and societal biases. Medical experts linked absinthe to violent crime, fueling the 'absinthe-induced violence' narrative. Sensationalized media reports, such as those detailing 'absinthe murders,' furthered the negative perception. While it's now understood that absinthe's dangers stem primarily from its alcohol content, not its essential oils, the ensuing panic led to its prohibition in Switzerland (1908) and France (1915). The widening consumption of absinthe, from the bourgeoisie to the working class, fueled its association with crime. The absinthe ban also reveals complex attitudes toward alcohol and societal prejudices. Although absinthe is now legal in some countries, its negative reputation persists.

OpenAI Outage: Unexpected Load from New Telemetry Service Causes Major Disruption

OpenAI experienced a major service disruption on December 11th, stemming from a newly deployed telemetry service. Intended to improve reliability, this service unexpectedly generated massive Kubernetes API server load, saturating the servers and causing the Kubernetes control plane to fail in most large clusters. This led to the breakdown of DNS-based service discovery. The incident highlights the unpredictable interactions within complex systems and the challenges of testing for failure modes that only appear under full load. OpenAI restored service by scaling down clusters, blocking network access to Kubernetes admin APIs, and scaling up API servers.

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.

Backward-Incompatible GRUB2 Change Causes BIOS Boot Loop

2024-12-16
Backward-Incompatible GRUB2 Change Causes BIOS Boot Loop

The author's Debian and Kali Linux systems experienced boot loops after a GRUB2 update added the command `fwsetup --is-supported`. Older GRUB versions didn't recognize this parameter. The issue stemmed from an older `efifwsetup.mod` module, leftover from a system backup restoration, causing a conflict between the new GRUB configuration and the old module. Installing the `grub-efi-amd64-bin` package resolved the problem. This highlights the importance of backward compatibility in software updates and the need to consider potential side effects when making partial changes in complex software like GRUB2.

Unraveling the Mango's Mystery: A Scientific Journey Across Asia

The sweet mango, a beloved fruit worldwide, hides a mysterious past. Dr. Emily Warschefsky, a Ph.D. student at Florida International University, embarked on a scientific journey across Asia to uncover the mango's origins. Visiting botanical gardens and forests, she collected numerous samples of Mangifera species and used DNA sequencing to study relationships between different mango species. Her research revealed genetic differences between Southeast Asian and Indian mangoes, challenging the traditional view of a single Himalayan origin. Several scenarios are proposed, including multiple domestication events and hybridization between different species. Warschefsky's work not only deepens our understanding of mango origins but also offers new insights for mango breeding and cultivation.
