The article discusses the potential of altered states of consciousness (ASCs), particularly in the context of psychedelic-assisted therapy for treating mental health disorders like depression and PTSD. It notes that access to such treatments is limited due to various barriers, which may make circular breathwork a more accessible non-pharmacological alternative. Initial scientific studies on breathwork are emerging, but its underlying mechanisms are not yet well understood. The research compares two types of breathwork—Holotropic and Conscious-Connected—and tracks physiological and

At the Craft conference in Budapest, Dan shared insights about the qualities that make the best programmers, inspired by a viral Twitter thread he wrote. He emphasized that the best programmer he knows, whom he's known for over 20 years, is not determined by conventional metrics like solving algorithmic problems or having a computer science degree. Rather, this programmer stands out due to his insatiable curiosity, belief in problem-solving capabilities, and a practical approach to programming. Dan highlighted several key traits of top programmers:

The article discusses the potential risks associated with using AI coding assistants, emphasizing that while they can enhance productivity, they may also introduce hidden vulnerabilities in the code. These vulnerabilities could manifest as malicious instructions disguised with Unicode tricks, making them difficult to detect. The initial time savings from using AI may lead to greater long-term issues, such as security breaches and increased technical debt, which can harm a project's sustainability and cause reputational damage. The author illustrates this risk through a scenario where seemingly benign, AI-generated code

The author describes a "slow code challenge" organized every few years by their research group, where the goal is to write code that achieves the lowest instructions per cycle (IPC) on a selected x86 server. Despite its absurdity, this challenge serves as an educational exercise to understand CPU functionality and how to exploit performance characteristics. The author notes that high IPC is difficult to achieve, even with efficient code, and distinguishes between code that is slow in intent (like a Python implementation of the Sieve of

Sidekiq, the leading background job framework for Ruby applications, has matured significantly over its 13 years, making major new features less common. A desired enhancement is thread-safe profiling, which was previously hampered by Ruby’s profiling APIs being process-global. However, with the introduction of Ruby 3.2, which features improved thread profiling APIs, Sidekiq 8.0 can now utilize this advancement for precise job profiling with minimal production impact. Profiling allows developers to identify exact performance bott

The author reflects on their experiences from 2020 and 2021, deciding to explore frameworks again, particularly focusing on creating a text label and an input field that can change the label's text. They mention that simpler tasks like this allow for easier completion but highlight that frameworks designed for scalability may struggle with initial setups. The writing serves as a development journal, offering insights as they work through the task. The author expresses newfound patience in dealing with challenges, such as manually downloading prebuilt .dll files

Cross-compiling refers to the process of compiling a program for a different machine than the one executing the compilation. While compilers historically targeted the host machine, today, most are cross-compilers to enable developments like creating iPhone apps without using iPhone hardware. Compilers identify and classify target platforms using "target triples," which describe the platforms for which they can generate executable code. This system has gained popularity, particularly with LLVM, leading most compilers to adopt target triples, such as x86_

Iron fertilization is a Carbon Dioxide Removal (CDR) technique aimed at combating climate change by artificially adding iron to the ocean’s surface. This process stimulates the growth of phytoplankton, tiny organisms that convert sunlight, water, and carbon dioxide into food and oxygen through photosynthesis. While oceans typically have sufficient nitrogen and phosphorus, they often lack trace nutrients, especially iron, which is crucial for phytoplankton growth. Natural occurrences, such as dust from the Sahara or volcanic ash,

NativeAOT and trimming are new .NET compiler options that help create applications with smaller sizes, faster execution, and lower memory usage. NativeAOT compiles to native machine code, while trimming removes unused code. However, for these options to be effective, the code paths must be statically determinable, which means that reflection cannot be used, as it may lead to critical code being removed. Most logging libraries utilize reflection, especially for structured logging, which formats messages in a key-value structure similar

Filip introduces an early version of an uncertainty calculator aimed at simplifying the understanding of statistics. He emphasizes that statistics can be daunting, but the core idea is about reasoning with uncertain numbers. Users can input exact numbers or ranges (using a tilde ~ to denote uncertainty), signaling confidence in those estimates. Filip highlights the importance of simplicity in this tool, as overcomplication can hinder understanding, especially for a broader audience. He advocates against treating uncertain numbers with disregard, promoting the idea that acknowledging uncertainty leads
