Coder's Million-Dollar Mistake: A Bug with a Dramatic Twist

Trey, a programmer working for a 3G telecom startup, wrote an automated payment testing program intended for small test transactions. Three bugs in the code, however, caused the program to credit his test account with $100 every five minutes. A lack of liveness check meant that when one gateway failed, the program continued running for hours, accumulating a substantial sum. The next morning, Trey faced questioning from the security team until his department head explained the situation, but the test account balance was reset to zero.

Debunking the RAM Myth: Optimizing Memory Access

This article challenges the common misconception about modern computer memory—the RAM myth—that assumes memory access is always random and uniform. By analyzing data sharding algorithms, the author demonstrates that simple linear algorithms are inefficient for large datasets due to frequent cache misses. To address this, an optimized strategy based on radix sort is proposed. Techniques like pre-sorting data, using generators, and pre-allocating memory significantly improve data sharding efficiency. Experimental results show that the optimized algorithm achieves a 2.5 to 9x speedup when processing large datasets.

C++: A Resurgence of Programming Fun

The author reflects on over a decade of programming, lamenting that languages like JavaScript, Python, and Ruby failed to recapture the joy he felt coding as a child. Recently, while developing a roguelike game using C++, he rediscovered that programming fun. He argues that C++ was once notorious for the overuse of template metaprogramming, but since C++11, the standards committee's efforts have revitalized the language. Additions like auto type inference, nullptr, and range-based for loops have significantly improved developer experience and efficiency. Modern C++ is powerful, boasting rich libraries and tools, yet avoids the negative aspects of excessive popularity. The relatively pure community allows developers to focus on creation, which is the essence of programming enjoyment.

Unveiling the Deep Connection Between Maximum Likelihood Estimation and Loss Functions

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.

Linear Algebra Powers Interactive Diagramming Editor

Ivan Shubin, in developing his interactive diagramming editor Schemio, cleverly used matrix operations from linear algebra to solve a series of challenging problems. Initially, Schemio only supported simple shape creation and manipulation. However, when a hierarchical structure was introduced, coordinate transformations became complex. The author initially used a recursive approach but encountered issues with scaling and pivot points. Ultimately, Shubin leveraged matrices to represent transformations (translation, rotation, scaling), using matrix multiplication for coordinate conversion and ingeniously employing matrix inversion to solve the world-to-local coordinate conversion problem. Furthermore, matrix operations addressed the precise adjustment of an object's position and rotation when moving within the hierarchy, preventing unexpected jumps. Schemio's source code is open-source and available on GitHub.

Open Source Firmware: Necessity and Strategic Choices

2024-12-17

This article explores the necessity of open-source firmware. The author argues that firmware, as software controlling hardware, should adhere to free software principles. This is not only about freedom itself but also directly related to users' practical interests. Non-free firmware can restrict hardware functionality, hide security vulnerabilities, and even prevent users from fixing security issues. The article analyzes two viewpoints: one considers open-source firmware desirable but not necessary; the other advocates that all system software should be open-source. The author leans towards the former, believing that prioritizing the freedom of the operating system kernel is more important, but simultaneously emphasizes the benefits of open-source firmware and discusses how to promote it through strategic means.

LLMs: Exploring Arithmetic Capabilities in the Pursuit of AGI

This article explores why large language models (LLMs) are being used for calculation. While LLMs excel at natural language processing, researchers are attempting to make them perform mathematical operations, from simple addition to complex theorem proving. This isn't to replace calculators, but to explore the reasoning capabilities of LLMs and ultimately achieve artificial general intelligence (AGI). The article points out that humans have always tried to use new technology for computation, and testing the mathematical abilities of LLMs is a way to test their reasoning abilities. However, the process of LLMs performing calculations is drastically different from that of calculators; the former relies on vast knowledge bases and probabilistic models, while the latter is based on deterministic algorithms. Therefore, LLM calculation results are not always accurate and reliable, highlighting the trade-off between practicality and research.

Newton Public Schools' 'Equity' Experiment Fails

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.
