Dev Turns Old PC into Pi-hole Ad Blocker to Learn Linux and Networking

0
·2 views

A developer learning Linux through MIT's Missing Semester course has decided to convert an old PC into a Pi-hole, a self-hosted DNS-level ad and tracker blocker. The project is intended as a hands-on way to build real skills in Linux system administration and networking rather than just completing coursework exercises. The old PC is expected to arrive on Tuesday, after which the developer plans to begin with OS installation and initial setup. Unlike typical write-ups, the process is being documented in real time, with mistakes included, to give an honest account of the learning experience.

Rust Gets WebForms Core Support via New webformscore Crate

A Rust implementation of WebForms Core, a server-driven UI technology developed by Elanat, is now available as the webformscore crate on Cargo. The library allows Rust developers to build interactive web interfaces by having the server generate commands that instruct the browser on how to update the HTML DOM, rather than manipulating it directly. On the client side, a separate JavaScript runtime called WebFormsJS receives and executes those commands against the DOM. The crate integrates with popular Rust web frameworks such as Actix Web and can be installed via the standard Cargo CLI. WebFormsJS is distributed independently through npm or its official repository, keeping the browser runtime decoupled from the Rust backend.

How Uber Predicts Your Driver's Arrival Time With Remarkable Accuracy

Uber calculates ETAs by dividing roads into roughly 100 million segments and measuring real-time crossing times using GPS pings sent by drivers every four seconds, effectively creating a free, city-wide traffic sensor network. Because live data only reflects the recent past, Uber built a deep learning system called DeepETA in 2022 to forecast traffic conditions up to three hours ahead, processing around two million requests per second. The model prioritizes fresh signals — such as a new accident — over historical patterns, and infers conditions on quiet roads from surrounding traffic data. A second correction model, trained on millions of completed trips, then adjusts for systematic errors like slow left turns or unaccounted stop signs. Uber reports that deploying DeepETA improved long-trip arrival accuracy by 6 percent, which the company estimates translates to approximately $100 million annually in retained gross bookings.

AICOM and AIMarket launch as linked AI factory and agent marketplace platform

AICOM is a multi-agent pipeline platform that takes a plain-language brief and moves it through thirteen specialized roles — including analyst, architect, developer, QA, and DevOps — to produce a deployable page. AIMarket serves as the connected marketplace where agents can discover capabilities, invoke them, and receive signed, verifiable receipts of completed work. Both platforms share the same MIT-licensed stack and are currently live, with guest access available at magic-ai-factory.com without requiring a login for the first build loop. The project also includes seventeen live mathematical oracles at oracles.modelmarket.dev and a chain-estimation studio called HEPHAESTUS at forge.modelmarket.dev. The team highlighted a key early lesson: using asyncio.gather without return_exceptions=True caused a single LLM timeout to cancel all parallel agents, underscoring that model failures in multi-agent pipelines are correctness issues, not just operational ones.

ChatGPT US Traffic Surged 48% Year-Over-Year in July 2026, Semrush Data Shows

Semrush Traffic Analytics estimates that chatgpt.com received approximately 1.09 billion US visits in July 2026, representing a 48.38% year-over-year increase. Over the same period, Bing referrals fell roughly 50%, while Google direct figures rose about 11%, though these metrics measure different signals and are not a direct market-share comparison. The data, drawn from a panel of around 200 million anonymized users, are third-party estimates rather than figures reported by OpenAI, Google, or Microsoft. Separate Semrush research found that outbound referral traffic from ChatGPT grew 206% during 2025, with about 21.6% of those referrals directed toward Google. For marketers, the findings highlight growing attribution challenges, as traffic originating in AI chat interfaces is harder to track consistently through standard analytics tools like GA4.
