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)

The article discusses how Nix and containers complement each other in software development, countering the notion that containers alone address all related issues. Nix provides a scalable and reliable way to create deterministic and reproducible Open Container Initiative (OCI) images, which can be deployed using various compatible tools. While containers focus on deploying software in isolated environments efficiently, Nix specializes in the packaging and building of that software beforehand. This distinction is crucial, as containers serve as transportation units for software, whereas Nix manages
