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

The article explores the intertwined histories of Vi and Vim with the development of open-source software and UNIX text editors. It reflects on the recent passing of Bram Moolenaar, Vim's creator, which prompted the author to contemplate the significance of Queen Mary University, where the first UK UNIX system was installed and where the em editor was developed by professor George Coulouris. This editor laid the groundwork for Vi and its clones. The author notes the text-centric nature of the UNIX shell, emphasizing the importance

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

The EdgeDB team is migrating a large part of their network I/O code from Python to Rust and is learning valuable lessons along the way. They are developing a new HTTP fetch feature using the reqwest library, which initially worked on x86_64 CI runners. However, they encountered intermittent test failures on ARM64 CI runners, appearing to be a deadlock but proving to be something different. The issue puzzled the team, particularly why it only affected ARM64. They speculated that the difference might

The article discusses small-group adventures inspired by fascinating places and their histories, focusing on a wishing well located about 50 miles northwest of London called Berryfields. This ancient site, once used by Romans for both water extraction and ritual purposes, has revealed numerous artifacts from 270 to 300 AD, including coins, ceramic pots, and bones. Archaeological excavations from 2007 to 2016 uncovered evidence of nearly two millennia of human activity, including Iron Age and medieval artifacts. Notably

The organization values community feedback and has recently open-sourced several libraries, receiving positive responses that have led to collaborations and bug fixes. Encouraged by this support, they plan to contribute their internal inference engine to the open-source community, acknowledging the essential role of open-source tools like PyTorch and vLLM in their development of DeepSeek models. While initially considering open-sourcing the full engine, they identified challenges and opted to collaborate with existing open-source projects instead. They express gratitude for the open-source

In this post, the author reflects on their misunderstanding of how the `git cherry-pick` command operates. Initially, they believed it simply applied a patch, but found this approach problematic when faced with merge conflicts. They note that this view, while mostly correct, is incomplete because it doesn't account for the underlying mechanics of the command. Upon investigating the Git source code, the author discovered that `git cherry-pick` actually performs a "3-way merge" rather than merely applying a patch. This

In Python, you can check if a list is empty using two methods: `if not mylist` and `if len(mylist) == 0`. The first method is generally preferred as it is considered more "Pythonic" and is around twice as fast as the second method. The performance difference arises from the underlying implementation in CPython, where `if not mylist` translates to fewer virtual machine (VM) instructions compared to `if len(mylist) == 0`. Specifically,
