The content provides an overview of a command-line benchmarking tool called Hyperfine, which is used to measure the performance of shell commands. Users can run benchmarks by simply executing `hyperfine <command>`, with the tool automatically determining the number of runs (defaulting to at least 10 runs and 3 seconds of measurement). Options such as `-r/--runs` allow users to adjust the number of runs, and `-w/--warmup` can be used to warm up the

The author reflects on their previous challenges with async/await systems, noting that issues with back pressure persist. They express a belief that async/await is not an effective abstraction across most programming languages and advocate for threads as a better alternative. The author draws attention to common assumptions among programmers regarding how code execution works, contrasting this with the understanding of children learning programming through Scratch, which uses a simplified model of actor-based programming. They illustrate this with an example of how experienced programmers might assume that actions in a

Transitioning from a monolithic architecture to microservices is a complex and lengthy process that requires careful planning and execution. A 10-part series is underway to address the common challenges of this migration, with the latest installment focusing on inter-service communication. Effective communication among microservices is crucial for the architecture's success, as it impacts both application functionality and user experience. The series emphasizes the importance of tailoring communication to the system's needs and planning for potential failures. The article discusses synchronous communication patterns like REST

On November 18, 2024, Google Scholar celebrated its 20th anniversary by sharing fun facts about its journey as a key resource for researchers globally. Launched in 2004 by two researchers, it aimed to simplify access to academic information, which was often restricted by paywalls. In its early days, Google Scholar faced challenges due to slow internet speeds, leading the team to physically collect research articles stored on hard drives, a method referred to as "Sneakernet." Over the years

The discussion focuses on Rust traits and highlights some of the problems associated with them, despite their popularity and historical significance in programming languages. Traits, akin to typeclasses in Haskell, protocols in Swift, or even interfaces, were well-regarded enough that their absence in certain languages, like Elm, led to requests and FAQs about their non-inclusion. A key issue outlined involves the challenges that arise when trying to implement traits for types that originate from different crates (libraries). The content presents a contrived

Bayesian inference can be applied to neural networks to learn a probability distribution over potential models, enhancing standard neural network techniques. This approach helps reduce overfitting, facilitates learning from limited datasets, and provides insight into the uncertainty of predictions. Deep neural networks are effective function approximators due to their vast number of adjustable parameters, enabling them to learn complex input-output relationships, which is beneficial for tasks like speech recognition and image classification. However, this high flexibility can lead to overfitting, where the model

The author previously explored various Go web frameworks for building a budget planning application and eventually created a simple version that needed deployment. Previous deployment methods included Terraform, GitHub Actions, and manual SSH, with the latter being used for the budget tracking app but lacking scalability. To enhance automation, the author discusses controlling Docker on a remote machine through the Go SDK and SSH without exposing the Docker API externally. Although the Go SDK can control Docker locally, managing remote instances typically involves the Docker REST API (which requires enabling

The author describes their use of the tool "git bisect" to identify the source of a regression bug. The process begins with the identification of a "good" commit (commit0001) from release-5.7.0, where the bug does not exist, and a "bad" commit (commit9999) where the bug is present as of October 21. This helps narrow down the search to 2,088 commits. Utilizing git bisect, the author employs a binary

The term "black company" (buraku kigyō) in Japan refers to exploitative employment systems, typically found in white-collar industries rather than blue-collar jobs. Coined by young IT workers in the early 2000s as an internet meme, it gained notoriety and often describes companies with ruthless and unethical work environments. The issue gained significant attention in Japan, particularly after the release of the 2009 film "A Man on the Verge at a BLACK Company," which depicted
