How to use a remote build server with Kamal Published: 2024-12-12 | Origin: /r/ruby The content discusses the creation and benefits of an external build server for Kamal deploys. By default, Kamal builds Docker images locally, but users can configure a remote builder for builds on a different host by specifying the remote connection. Local builds will continue as long as the local host's architecture matches the specified settings, but users can opt for remote builds by setting local to false. Kamal only submits build requests to the server and requires Docker to be installed on the build server. The remote |
Value-based type validation in Rust for Node.js applications Published: 2024-12-12 | Origin: /r/programming On Day 4 of Launch Week, Encore.ts has introduced advanced value-based validation support, enhancing its already intuitive request and response type definitions using TypeScript. This new feature ensures both compile-time and runtime type safety, responding with a 400 error for malformed requests. In addition to verifying field presence and types, value-based validation allows users to check that values fall within acceptable ranges or match specific patterns using the TypeScript type system for rule definition. The validation is executed in Rust for exceptional performance, making |
A ChatGPT clone, in 3000 bytes of C, backed by GPT-2 (2023) Published: 2024-12-12 | Origin: Hacker News Nicholas Carlini describes a dependency-free implementation of GPT-2 in approximately 3000 bytes of C code. This program loads the weight matrix and BPE file from original TensorFlow files, tokenizes input, performs matrix operations for inference, and decodes output using BPE. The implementation is optimized for speed, allowing GPT-2 Small to generate replies in a few seconds on modern hardware through techniques like KV caching and efficient matrix multiplication with optional parallel processing. While the output quality is considered poor |

New Jersey Governor Phil Murphy held a briefing with the US homeland security secretary and local officials, reassuring that there is |
FP For The Working Programmer: Why Is null Bad? Published: 2024-12-11 | Origin: /r/programming The author discusses the dangers of null values in programming, highlighting how languages like C/C++ can lead to hard-to-trace bugs when accessing null pointers. Java improves on this by failing immediately when a null pointer is accessed, which aids debugging. However, the problem remains that traditional type systems do not differentiate between present and absent values due to the ubiquitous nature of null. Newer languages such as Scala introduce an Option type, which explicitly represents a value that may or may not exist—either as Some |
