Programming for distributed systems hasn't seen fundamental improvements in the last decade. Current approaches rely on band-aids over existing paradigms like external-distribution, static-location, and arbitrary-location, each with limitations in performance, control, or semantic clarity. There's a need for a new programming model that is native to distributed systems that has things like semantic locality and can surface potential issues from network delays and faults.
HTTP/2 support in Ruby HTTP servers like Puma isn't necessary because its primary benefit, multiplexing, is most impactful over the internet with high latency. Within a datacenter, the low latency between the application server and load balancer takes away the advantage of HTTP/2. Furthermore, features like server push, once a motivation for end-to-end HTTP/2, have been abandoned, so HTTP/2 is best handled at the infrastructure entry point (load balancer or reverse proxy) to avoid unnecessary complexity within the application server.
OpenAI has released a research preview of GPT-4.5, their new advanced chat model. It's their biggest model yet, with improvements in its ability to recognize patterns, draw connections, and generate insights. It also has more "EQ" and a better understanding of human intent.

A bill (SB0226) is being considered by the Illinois General Assembly to address whether public bodies can hide information from Freedom of Information Act (FOIA) requests by storing it in databases. This bill was prompted by Matt Chapman's FOIA request for the City of Chicago's parking ticket database (CANVAS) schema, which was denied due to security concerns. Chapman sued, bringing in the author of this article as an expert witness to argue that releasing the schema wouldn't jeopardize the system, but despite winning at trial and appellate court, the Illinois Supreme Court ultimately sided with the city, defining a schema as a file layout, which is exempt.
OpenAI's Deep Research is designed to make research and analysis easier, but it often falls short of expectations due to inaccuracies and unreliable data sourcing. For example, a sample report on smartphone adoption rates contained flawed data from sources like Statcounter and Statista, leading to incorrect conclusions.
