The author encountered a severe issue with their machine, experiencing 3,200% CPU utilization across all 32 cores, compared to a prior case of 100% usage on a single core. Using Java 17, they analyzed thread dumps to identify a problematic section in the code located at BusinessLogic:29, where a loop incorrectly iterated over an unrelated object instead of the relevant one. They suspected that refactoring had made the unrelated object redundant. To test their hypothesis, they ran unit

In her article, Miriam Suzanne emphasizes the importance of using relative units like em and rem for text sizing in web design, highlighting their role in ensuring compatibility with user preferences and maintaining consistent typography. She discusses how the default text size set by browsers can be leveraged by establishing a root font-size with em values, which allows for a scalable relationship across various font sizes. Suzanne also introduces the concept of fluid typography, which incorporates viewport or container-relative units and the clamp() function to create responsive text sizing within defined

The feedback from users is valued and taken seriously. Significant updates have been made to the fish shell, including a transition of core code from C++ to Rust, which alters dependencies and building procedures, though it won't impact users directly. Key changes include: - A new key notation for bindings due to a binding rework, with legacy notation still functional in most cases. - The `ctrl-c` command now invokes `clear-commandline`, while the previous behavior can be accessed via `cancel-commandline

In 2006, Robert Andersen made history by sending the first tweet that mentioned another user, giving rise to the @mention convention. At that time, Twitter operated primarily through SMS, lacking features like threads and @username autocomplete. Users had to manually type @mentions and faced a 140-character limit, influenced by SMS's 160-character restriction. This text-based service also meant that Twitter does not support formatted or rich text. To navigate these constraints, users creatively utilize Unicode characters, generating various text

The author plans to write about Pitchfork, its origins, current state, and future but first wishes to discuss Ractors, a feature announced 4-5 years ago that many expected to revolutionize web server development, similar to the existing Puma server. However, practical implementations have been scarce, aside from some experimental projects. Ractors are designed to enable true in-process parallelism while maintaining the Global VM Lock (GVL). They avoid sharing mutable objects between Ractors and instead allow them to share

Andrew Ng has launched a new document extraction service that quickly gained attention on social media, but initial tests by Pulse revealed disappointing results, particularly with complex financial statements. The testing uncovered significant issues, as even a 99% accuracy rate could result in 2,000 incorrect entries across large document sets, jeopardizing critical financial decisions. Users have expressed a need for over 99.9% accuracy for essential operations. The inherent problems with using probabilistic large language models (LLMs) for document extraction

Markov chains, named after Andrey Markov, are mathematical systems that transition between various states, which can represent different situations or values. For instance, in modeling a baby's behavior, states could include "playing," "eating," "sleeping," and "crying." A Markov chain not only defines a state space (the possible states) but also specifies the probabilities of transitioning from one state to another. A basic example illustrates a two-state Markov chain (states A and B)
