Popping the GPU Bubble (17 minute read)
AI models typically produce one token at a time - you can't compute the third token before you have the second. The GPU does most of the heavy lifting, but there is also some work that needs to be done by the CPU. GPU bubbles occur when the GPU sits idle in a loop waiting for the GPU to complete its job. This article looks at how to hide these bubbles using a technique called pipeline decoding, which involves starting the GPU work on the next token while the CPU is still finishing the last one.

The iPhone 18 Pro just leaked, and it might be the single biggest Apple leak since the iPhone 4 (2 minute read)
Alleged leaked files from Indian supplier Tata Electronics, including grainy drop-test photos, appear to show the Apple iPhone 18 Pro with a design that is almost identical to the Apple iPhone 17 Pro, featuring the same large camera module and rear glass cutout. The most noticeable changes are improved color matching around the rear glass, eliminating the two-tone appearance, and hints that a new deep red color option may be introduced, with many online commenters joking that it looks like an "iPhone 17.01." The comparison to the famous Apple iPhone 4 leak highlights how dramatically iPhone design evolution has slowed, making the familiar-looking design one of the reasons many people find the leak believable.

Securing AI agents: When AI tools move from reading to acting (6 minute read)
Enterprise AI agents are starting to run tasks across business systems via MCP-connected tools, which opens the door to data theft when tool metadata is poisoned. A finance-focused Copilot Studio agent example shows how hidden instructions in an enrichment server's description quietly pull unpaid invoice data and send it to an attacker-controlled endpoint, all while remaining within normal permissions and workflows. Microsoft recommends treating MCP servers and descriptions as part of the supply chain, inspecting metadata, restricting tool access, and using DLP, Sentinel, and Guardrails to monitor and block risky actions.
