Raspberry Pi 500 Modder Successfully Adds M.2 Slot

2024-12-15

A Raspberry Pi enthusiast successfully added an M.2 slot to the Raspberry Pi 500! While the Pi 500 has the header, the slot itself is absent, leading to some controversy. The modder soldered on four tiny capacitors and used a bench power supply to power a bottom pad, enabling the use of NVMe SSDs and other PCIe devices. This modification requires excellent SMD soldering skills and has sparked discussion about the Pi 500's design choices; speculation includes reserving the feature for a future premium model.

Efficient Cloud-Native Raster Data Access: An Alternative to Rasterio/GDAL

2024-12-15

The exponential growth of Earth observation data in cloud storage necessitates efficient access and analysis of satellite imagery. This article introduces an alternative cloud-native raster data access approach to Rasterio/GDAL. Traditional GeoTIFFs are inefficient, while Cloud-Optimized GeoTIFFs (COGs) improve efficiency through tiling and multi-resolution access. However, even with COGs, tasks like time-series NDVI analysis suffer from latency. The authors leverage STAC GeoParquet, combined with pre-calculated byte ranges, to reduce HTTP requests, significantly speeding up data access. Initial tests show this approach drastically reduces time-to-first-tile for Sentinel-2 data and lowers costs. A future open-source library, "Rasteret," will implement these techniques.

Negotiating with Infringers: A Better Option for Creative Professionals

2024-12-16

When a creative professional's copyright is infringed, litigation isn't the only option. This article's author, a lawyer, suggests considering negotiation with the infringer. Negotiation is quicker and cheaper than litigation and may yield benefits beyond monetary compensation, such as promotion and collaboration opportunities. The author points out that most infringements are not malicious but due to negligence. Through negotiation, adversaries can be transformed into collaborators, leading to long-term success. Of course, if negotiations fail, litigation remains a last resort.

Newton Public Schools' 'Equity' Experiment Fails

2024-12-14

In the fall of 2021, Newton Public Schools in Massachusetts implemented a complex initiative called "multilevel classrooms" aimed at improving educational equity. This model mixed students of varying academic abilities into single classrooms with one teacher. Three years later, the results are troubling. Teachers report the model fails to meet the needs of diverse learners; high-achieving students are stifled, while lower-achieving students are hesitant to ask questions. Lack of adequate training and support for teachers led to poor outcomes, with students in multilevel classes often underperforming their single-level counterparts. The school lacked metrics for success, and no data supported the model's efficacy. A teacher's council petitioned to roll back multilevel classes in STEM and world languages, urging the district to find better solutions for addressing educational equity. The failure highlights the need for data-driven approaches and a focus on student needs in educational reform.

Unveiling the Deep Connection Between Maximum Likelihood Estimation and Loss Functions

2024-12-15

This article delves into the intrinsic relationship between Maximum Likelihood Estimation (MLE) and commonly used loss functions. Starting with the fundamentals of MLE, the author meticulously explains its close connection to KL divergence. The article then uses Mean Squared Error (MSE) and Cross-Entropy as examples, demonstrating how these functions are naturally derived from MLE rather than being arbitrarily chosen. By assuming data distributions (e.g., Gaussian for linear regression, Bernoulli for logistic regression), maximizing the likelihood function via MLE directly leads to MSE and Cross-Entropy loss functions. This provides a clear path to understanding the theoretical underpinnings of loss functions, moving beyond mere intuition.

WASM Program Bypasses node:wasi Filesystem Sandbox

2024-12-15

This project demonstrates a proof-of-concept showcasing how a WASM program can bypass the preopens directory restriction in node:wasi to access files outside the sandbox. Normally, WASM programs are limited to accessing pre-opened directories. However, by cleverly using symbolic links to replace files at a precise moment and running an external process, this limitation can be circumvented. This is not a practical security vulnerability in node:wasi, but rather a potential edge case. The project highlights that one shouldn't rely on node:wasi to completely prevent malicious code from accessing external files.

Victorian Novels Highlight Fragility of Public Health

2024-12-15

Victorian-era novels reveal the shockingly high child mortality rates from infectious diseases, underscoring the fragility of public health today. The article highlights that in the first half of the 19th century, 40-50% of children in the U.S. died before age 5, with similar rates in UK slums. Tuberculosis, smallpox, and diphtheria were major killers. However, advancements in sanitation, regulations (food safety), and medicine (vaccines, antibiotics) have drastically reduced child mortality. Victorian novels, with their poignant depictions of grief over lost children, serve as a cautionary tale: the progress made is not guaranteed and complacency regarding public health measures, such as vaccination rates, could lead to a resurgence of deadly diseases.
