• USB Power Delivery is described as extending USB-C to support up to 240W of power and 80Gbps of data.
• The guide covers both practical design topics and standards history, including alternate modes, controller needs, and USB PD 3.1 evolution.

GrapheneOS recommended for domestic abuse victims

Key Points

• The article says technology-facilitated abuse is widespread in domestic violence cases and increasingly affects children as well.
• PrivacyPros recommends DV Safe Phones as a way to reduce tracking and monitoring risks through privacy-focused configuration.
• GrapheneOS on recent Google Pixel devices is presented as the article's preferred setup because of its security and privacy features.

Old Icons

Key Points

• Early Mac app icons were 32×32 pixels, monochrome, and built around a consistent visual template.
• Apple’s original icon language used tilted rectangles and protruding hands to distinguish applications from documents.
• As the Mac platform matured, Apple and third-party developers moved away from those strict icon conventions.

How Has Roman Concrete Lasted for Millennia? 1,900-Year-Old Latrine Offers Clues

Key Points

• New research suggests carbonation helped Roman concrete remain durable for centuries by forming crack-filling calcite.
• Scientists studied an undisturbed concrete sample from a 1,900-year-old latrine at Hadrian’s Villa near Rome.
• The findings could support development of lower-impact, longer-lasting modern concrete.

What loss.backward() actually does

Key Points

• `loss.backward()` computes gradients of a scalar loss with respect to upstream parameters by propagating derivatives backward through the computation graph.
• Backpropagation relies on local derivatives for each operation and the chain rule to combine them across paths.
• Backward mode is efficient for neural networks because one backward sweep yields gradients for many parameters connected to a single loss.

Pebble Mega Update – July 2026

Key Points

• Pebble says it has built over 23,000 Pebble Time 2 watches and fulfilled more than 80% of preorders.
• Battery-life optimizations reportedly raised Pebble 2 Duo median endurance to over 30 days, with Pebble Time 2 at about 21 days.
• Pebble and Moddable released SDK updates adding touchscreen, speaker, and RGB backlight APIs.

UIUC AI Teaching Assistant

Key Points

• The UIUC electrical engineering teaching assistant runs 11 models in parallel and reports a 2-second median response time.
• Its RLHF workflow uses semantic search retrieval and a public Hugging Face dataset tailored to ECE 120.
• The project is open source except for restricted textbook content and can be adapted using a custom Pinecone document database.
