Implementing a Simple Pool Allocator in C

2025-01-09

This article details the implementation of a simple pool allocator in C. The author first presents a fixed-size pool implementation with O(1) time complexity for allocation and deallocation. This is then improved to allow dynamic resizing, preventing crashes due to exhaustion of the initial pool. The improved version cleverly uses linked lists to manage memory blocks, balancing performance with efficient memory usage.

Layoffs: You'll Never Be the Same

A year after being laid off, the author reflects on the experience. The article details warning signs preceding the layoff: cancelled team events, unexpected package notifications, lack of leadership vision, vague mandatory meetings, and the timing around quarterly results. The author emphasizes that even high performance may be disregarded during layoffs, reducing employees to mere rows in a spreadsheet. The author reflects on the broken trust in modern work and advises those yet to be laid off to stick to contract hours, protect personal time, continuously interview, leverage external offers for salary increases, and not overthink their resumes. Ultimately, the layoff fundamentally altered the author's perspective on work, leaving them disillusioned.

Ancient DNA Rewrites the Story of the First Americans

2025-03-21

Genetic studies are revolutionizing our understanding of how the Americas were first populated. Analysis of ancient DNA from remains across the continent, including a remarkably well-preserved 24,000-year-old Siberian boy, reveals a more complex picture than previously thought. Rather than a single migration from East Asia, multiple waves of migration from diverse Asian populations, including groups related to both Ancient North Siberians and East Asians, contributed to the genetic makeup of Native Americans. Some groups may have experienced a prolonged period of isolation in Beringia before migrating south. The findings also highlight genetic links between early Americans and ancient Japanese populations, painting a richer and more nuanced picture of the peopling of the Americas.

Microsoft Wants You Off Windows 10 in 2025

Microsoft is ending support for Windows 10 in October 2025, pushing users towards Windows 11. The company is branding 2025 as 'the year of the Windows 11 PC refresh,' arguing that upgrading is more crucial than buying new TVs or phones. Despite full-screen upgrade prompts throughout 2024, Windows 11 adoption lags behind Windows 10. While Microsoft isn't exhibiting at CES 2025 in the traditional sense, its presence is felt through numerous partners integrating Windows 11 and Copilot AI.

Swift's New Forked Framework Simplifies Shared Data Management

Developer Drew McCormack launched Forked, a new Swift framework for simplifying shared data management across single and multiple devices. Inspired by Git's merge mechanism, Forked supports branching and merging within a single file, achieving eventual consistency. It doesn't require a complete change history, only enough versions for three-way merging. Forked uses structs instead of classes, supports Codable, and seamlessly integrates with cloud services like iCloud. It even tackles race conditions from concurrent access and supports custom merge logic or built-in CRDT algorithms. CloudKit sync is achieved with just a few lines of code.

The VUS Problem in Genetic Testing: Can AI Provide a Solution?

Genetic testing has advanced rapidly, but the interpretation of 'variants of unknown significance' (VUS) remains a major challenge in clinical genetics. VUS, genetic variations with unclear health implications, cause significant patient anxiety. This article explores strategies to tackle the VUS problem, focusing on multiplexed assays of variant effect (MAVE) to generate large functional datasets and leverage AI to improve prediction tools. While a complete solution remains elusive, MAVE and AI offer hope for precision medicine, promising to greatly enhance the diagnostic accuracy of genetic testing in the future.

The UK's Competition and Markets Authority (CMA) is investigating Ticketmaster following the sale of Oasis reunion tour tickets, which resulted in outrageously inflated prices and numerous customer complaints. The CMA's concerns center on Ticketmaster's labeling practices and information provision. They found that Ticketmaster sold 'platinum' tickets at more than double the standard price without adequately informing consumers that this didn't guarantee better seats or perks. The CMA also criticized Ticketmaster's handling of standing room tickets, where cheaper tickets were sold out before more expensive options were presented to those waiting online.

Iterated Log Coding: A Novel Floating-Point Encoding Format

2025-02-26

This article introduces a novel real number encoding format—iterated log coding. Unlike traditional floating-point representations, this format uses a sequence of sign bits to represent numbers, each sign bit indicating the positivity or negativity of the number within a specific range. This approach allows for a remarkably wide range of representable numbers, including extremely large or small values that are beyond the capabilities of traditional floating-point formats. It features a unique lexicographic ordering property. While the precision distribution is non-uniform, the method offers advantages in representing numbers within certain ranges, particularly where extremely large or small values are involved and precision requirements are less stringent.

Mechanical keyboard company Qwertykeys has temporarily suspended all shipments to the US due to President Trump's tariffs on Chinese goods. The 45% tariff increase, coupled with DHL's new requirement for a 50% prepayment of declared value plus a $21 processing fee per package, makes shipping unsustainable. Qwertykeys is pausing shipments for 72 hours to negotiate with DHL and other logistics providers for fairer solutions.

Solidity Compiler Crash: A Perfect Storm of Ancient Bugs

Solidity Compiler Crash: A Perfect Storm of Ancient Bugs

A perplexing crash in the Solidity compiler has recently emerged: it segfaults even when compiling perfectly valid code. The root cause was traced to a 12-year-old overload resolution bug in G++ versions below 11.4, interacting with C++20's implicit comparison rewrite rules when handling Boost's `boost::rational` type. This combination leads to infinite recursion and a stack overflow. The issue isn't in the Solidity code itself, but a surprising interaction between G++, Boost, and the C++20 specification. The solution is upgrading Boost to 1.75 or higher, or upgrading G++ to version 14 or later.

10x Programmer: How to Dramatically Increase Your Coding Speed

2025-02-20

This post argues for the importance of improving coding speed. The author compares the development time of two similar libraries, six and two years apart, demonstrating at least a 5x, and potentially 20-30x speed increase. This improvement stems from clearer goals, faster design decisions, and improved work processes. The author suggests a potential 10x speedup is achievable by improving mechanical skills like typing speed, reducing bugs, and refining workflows. This translates to more output, broader project choices, and more learning opportunities. The post explores the impact on project selection, feedback loops, tool development, and uses SQLite's optimization as an example of how small, incremental improvements compound to significant gains. The author concludes that increased speed is also more enjoyable.

Concurrent programming is notoriously complex due to the difficulty of enumerating all possible states. This article uses visualization to explain how to understand the mechanics of concurrent program execution. It begins by introducing the concept of program state, which is a combination of variable values and instruction location, and then demonstrates the transition process of program states and the generation of state space using a simple C-like program example. The article then introduces concurrent programs, and, using two concurrently executing programs, P and Q, it explains how to represent the state of a concurrent program and the construction of the state space. Finally, the article explores how to use the model checking tool SPIN and the LTL language to verify the correctness of concurrent programs, highlighting the important role of model checking in ensuring the correctness of concurrent programs.
