In this web content, the author gives a lightning talk about where computers get their time from. They explain that computers get the time from NTP servers, which in turn get it from other NTP servers, eventually leading to reference clocks like GPS receivers. The author notes that GPS gets its time from Schriever Space […]
In this study, we examine the capabilities of large language models (LLMs) to determine whether they simply learn superficial statistics or if they develop a coherent model of the data generating process, also known as a world model. Through analyzing the learned representations of various spatial and temporal datasets in the Llama-2 family of models, […]
Extism aims to make WebAssembly (Wasm) easier to use by streamlining the developer experience across languages and platforms. While Wasm allows programs to run almost anywhere, it can be difficult to harness its power due to the differences in language platforms and the challenge of communicating with guest Wasm programs. Extism solves these issues by […]
In this web content, the author explores a feature implemented by Microsoft that limits the amount of memory a process can use. The author highlights several issues with this feature: it was not documented, it does not actually save memory, and it can result in high CPU costs. The author shares their investigation into a […]
In the world of semantic search and retrieval-augmented generation (RAG), vector databases play a crucial role that often goes unnoticed. If you’re exploring applications like large language models or semantic search platforms, choosing the right vector database is essential. To simplify the decision-making process, this article compares the leading vector databases of 2023, including Pinecone, […]
Shuttle is a cloud development platform designed specifically for Rust apps. It offers a range of features to enhance productivity, reliability, and performance. This includes zero-configuration support for Rust using annotations, automatic resource provisioning, and first-class support for popular Rust frameworks. One unique aspect of Shuttle is its ability to deploy Discord bots using Serenity. […]
OpenSSH 9.5 has been released and it comes with significant changes. One of the key features is a transport-level ping mechanism and keystroke timing obfuscation. This obfuscation hides inter-keystroke timings by sending interactive traffic at fixed intervals, and it also sends fake “chaff” keystrokes after the last real keystroke. These changes are controlled by a […]
The Google Pixel 8 and 8 Pro will offer a remarkable seven years of software support, meaning users can expect to use them until 2030 without their software becoming outdated. This is a significant improvement compared to previous offerings from Google, which provided only five years of security updates and three years of Android OS […]
Anna’s Archive has scraped all of Worldcat, the world’s largest library metadata collection, to create a TODO list of books that need to be preserved. They are hosting a data science mini-competition to invite others to analyze the data and discover interesting insights. The dataset consists of Worldcat library records from various OCLC member libraries, […]
