Outdated Laws Fuel Anti-Immigrant Violence in UK: Social Media's Role in the Southport Tragedy

A parliamentary investigation reveals how outdated laws hampered police efforts to counter disinformation on social media, exacerbating anti-immigrant violence in the UK last summer. Following the stabbing deaths of three children in Southport, false reports portraying the attacker as a recent Muslim migrant fueled days of rioting by far-right activists. Contempt-of-court rules and restrictions on naming underage suspects hindered the police's ability to correct misinformation, allowing false narratives to spread rapidly. The committee calls for government support to monitor social media and review contempt of court laws to address the challenges of the social media age.

Bypassing Censorship: The Unexpected Use of Unencrypted HTTP/2

2025-04-14

Researchers discovered that unencrypted HTTP/2 can bypass censorship in China and Iran. Despite the lack of browser support for unencrypted HTTP/2, they found that up to 6.28% of websites support it. They developed a tool to evaluate website support for unencrypted HTTP and suggest this finding adds to existing censorship circumvention techniques. Importantly, unencrypted HTTP/2 is not secure and should not be used for sensitive data.

Peak Demand: A Seismic Shift in Global Oil Markets

Peak Demand: A Seismic Shift in Global Oil Markets

This New York Fed article explores a pivotal shift in global oil markets. The once-prominent 'peak oil' theory, predicting declining oil production, was overturned by the shale revolution. Now, a new 'peak demand' narrative suggests that the rise of EVs and other low-carbon technologies will flatten and eventually decrease global oil consumption. This transforms the market into a zero-sum game, where production growth in one region lowers prices, squeezing out higher-cost producers elsewhere. The article analyzes the adaptability of US shale producers and the impact of EV adoption, noting that while some agencies predict peak oil demand around 2030, others foresee continued growth. Ultimately, global oil markets are transitioning from supply-driven to demand-driven dynamics, with profound implications for the global economy and energy landscape.

Entropy: Unraveling the Universe's Arrow of Time

Entropy: Unraveling the Universe's Arrow of Time

This article provides an accessible explanation of entropy. Entropy isn't simply 'disorder,' but rather a measure of uncertainty within a system. From an information theory perspective, entropy represents the number of bits needed to communicate a system's state; from statistical mechanics, it's related to the number of microstates corresponding to a given macrostate. Using the example of balls in a box, the article illustrates the impact of macrostates, microstates, and coarse-graining on entropy and explains why time has a direction: the universe began in a low-entropy state, and systems evolve toward higher entropy states, not because physical laws are irreversible, but because high-entropy states are far more probable. The article also addresses seemingly entropy-violating phenomena, such as oil and water separation, showing that entropy actually increases when all system attributes are considered.

Monte Carlo Sampling Crash Course: Rejection Sampling and Change of Coordinates

2025-04-14

This article introduces two crucial sampling techniques in Monte Carlo methods: rejection sampling and change of coordinates. Rejection sampling samples a simpler region and filters samples based on an acceptance probability to achieve sampling of a complex region. The article provides a detailed derivation of the probability density function for rejection sampling and extends it to non-uniform distributions. Change of coordinates utilizes the Jacobian determinant to map samples from a simple region to a complex region, enabling efficient sampling. The article uses the unit disk as an example, demonstrating how to achieve uniform sampling using polar coordinate transformation. Both methods have their advantages and disadvantages; rejection sampling is simple and easy to understand but its efficiency depends on the acceptance probability; change of coordinates is efficient but requires finding suitable coordinate transformations.

Optimizing ESP32 OLED Driver: Speed vs. Font Support

The author experimented with several drivers for an SSD1306 OLED display on an ESP32, ultimately settling on a modified, deprecated driver. Initially, an Espressif driver was used, but it only supported a single font. Subsequent attempts with LVGL and U8G2 suffered from low refresh rates. The author returned to the deprecated driver, adapting its I2C API calls for compatibility with the latest ESP-IDF, achieving a 40Hz refresh rate. To add font support, the nvbdflib library was integrated, directly parsing BDF fonts and drawing to the framebuffer, resulting in high-speed refresh and custom font capabilities.

The Pragmatist's Guide to Functional Programming: Macro over Micro

2025-04-14

This essay argues against a purely micro-level application of functional programming principles in imperative languages. While acknowledging the benefits of functional programming, the author contends that obsessively replacing for loops with maps and reduces without addressing higher-level architectural concerns often yields minimal gains or even negative results. The true value lies in adopting macro-level principles like managing mutation, simplifying architecture, and strengthening type systems. The author advocates for a pragmatic approach, prioritizing architectural design and code quality over strict adherence to functional micro-styles, suggesting a portfolio of 80/20 solutions often surpasses a single 100/100 approach.
