Storing Times for Human Events: Best Practices and Challenges

2024-12-12

This blog post discusses best practices for storing event times on event websites. The author argues that directly storing UTC time loses crucial information, such as the user's original intent and location. A better approach is to store the user's intended time and the event location, then derive the UTC time. Examples like user error, international timezone adjustments, and the 2007 Microsoft Exchange DST update illustrate the importance of storing the user's intended time. The author recommends designing a clear and user-friendly interface to help users accurately set event times and locations, emphasizing the importance of maintaining the user's original intent to avoid errors caused by timezone changes.

Demonic Possession Predicted the Fall of the Carolingian Empire

2024-12-13

In the early 9th century, a Frankish courtier recorded a tale of demonic possession. The demon, Wiggo, confessed to destroying crops, livestock, and spreading plagues, blaming the Franks' sins and their rulers' many crimes. Wiggo described rampant greed, mutual suspicion among rulers, and lack of piety. This story mirrored the crisis of the Carolingian Empire: internal strife, economic instability, and famine. The courtier, Einhard, used this tale to subtly criticize the rulers' corruption and foreshadow the empire's decline.

The Humble For Loop in Rust: Performance and Readability

2024-12-12

This article explores the trade-offs between the humble `for` loop and functional programming approaches like `map` and `fold` in Rust, considering both performance and readability. Through benchmarks comparing different methods on vector and nested vector operations, the author finds that `map` often outperforms `for` loops in simple transformations, offering better declarative style. However, for more complex scenarios such as flattening nested vectors or handling errors, `for` loops demonstrate a significant performance advantage and maintain greater code clarity. The author advocates for a pragmatic approach, choosing the best tool for the job rather than blindly favoring functional programming.

AI Scaling Laws: Beyond Pre-training, a New Paradigm Emerges

2024-12-12

This article explores the evolution of AI scaling laws, arguing that they extend beyond pre-training. OpenAI's o1 model demonstrates the utility and potential of reasoning models, opening a new, unexplored dimension for scaling. The article delves into techniques like synthetic data, Proximal Policy Optimization (PPO), and reinforcement learning to enhance model performance. It clarifies that Anthropic's Claude 3.5 Opus and OpenAI's Orion weren't failures, but rather shifts in scaling strategies. The authors emphasize that scaling encompasses more than just increasing data and parameters; it includes inference-time compute, more challenging evaluations, and innovations in training and inference architecture.

Stripe Investigates Unexpected DNS Error Spike: A Tale of Complex Network Troubleshooting

2024-12-12

Stripe recently experienced an unexpected spike in DNS errors. This post details how they used tools like Unbound, tcpdump, and iptables to track down the root cause. The investigation revealed that a Hadoop job analyzing network logs was performing numerous reverse DNS lookups (PTR records), leading to traffic amplification due to retries exceeding the AWS VPC resolver's limits. Stripe resolved the issue by adjusting Unbound forwarding configurations to distribute the load across individual Hadoop hosts. The case highlights the importance of robust monitoring, multi-faceted troubleshooting, and strategies for handling traffic surges in high-availability systems.

Qubes OS Unveils Secure PDF Conversion Tool

2024-12-12

The Qubes OS team has developed a novel security mechanism for converting untrusted PDFs into trusted ones. Leveraging Qubes' Disposable VMs, the process isolates PDF parsing within a secure container. The PDF is converted to a simple RGB image representation, then back to a PDF. This approach effectively mitigates attacks from malicious PDFs; even if parsing fails, the resulting PDF will only be a corrupted image, posing no system threat. This innovation significantly enhances Qubes OS security, allowing users to handle PDFs from the web or email more safely.

Bizarre Particle's Mass Depends on Travel Direction

2024-12-12

Scientists have unexpectedly discovered a strange quasiparticle, a semi-Dirac fermion, in a ZrSiS material. This particle exhibits a peculiar behavior: it's massless when moving along a specific direction but gains mass when traveling in other directions. This discovery, stemming from research into the properties of quasiparticles within ZrSiS, relates to Einstein's mass-energy equivalence, E=mc². When moving at light speed in a specific direction, the quasiparticle is massless; changing direction and slowing down causes it to gain mass. The finding could potentially lead to novel applications for ZrSiS, similar to those of graphene.

The Marvelous Disappearing Capacitor: A Clever Trick to Improve Photodiode Amplifier Performance

2024-12-12

This article introduces a clever technique to improve the performance of photodiode amplifiers: bootstrapping. The parasitic capacitance of a photodiode limits its ability to amplify rapidly changing signals. In a traditional transimpedance amplifier (TIA), this capacitance reduces bandwidth. The article analyzes the working principle of a TIA, explaining how the photodiode's parasitic capacitance affects circuit performance. The author presents a bootstrapped circuit using an op-amp and JFET, which effectively eliminates the parasitic capacitance by keeping the voltage across the photodiode terminals virtually the same, significantly improving bandwidth. The article also discusses a variant AC-coupled bootstrapped circuit and provides relevant formulas.

New Study Pinpoints Neanderthal Interbreeding with Modern Humans

2024-12-13

A new analysis of ancient DNA from modern humans in Europe and Asia has precisely determined the timeframe of Neanderthal interbreeding with Homo sapiens. The interbreeding began approximately 50,500 years ago and lasted for about 7,000 years, until Neanderthals began to disappear. This research, using 58 ancient genomes and present-day human genomes, revealed an average interbreeding date of around 47,000 years ago, consistent with archeological evidence. The study also found that East Asians possess about 20% more Neanderthal genes than Europeans and West Asians, potentially due to the presence of mixed genes when modern humans migrated eastward around 47,000 years ago. The findings offer a more complete picture of past human migrations and gene flow, and shed light on the impact of Neanderthal genes on modern human health.
