OpenTPU: An Open-Source Reimplementation of Google's TPU

UC Santa Barbara's ArchLab has released OpenTPU, an open-source re-implementation of Google's Tensor Processing Unit (TPU). Based on details from Google's research paper, but lacking a formal specification, OpenTPU differs in several implementation details from Google's design. Currently supporting matrix multiplication and ReLU/sigmoid activation functions, OpenTPU is missing features like convolution and pooling. Implemented using PyRTL, the project includes hardware and functional simulators, along with a checker for verifying results. While lacking hard synthesis figures for a full 256x256 OpenTPU at this alpha release, its open-source nature offers valuable learning and improvement opportunities for researchers.

Apple's New AI Breakthrough: Fine-Grained Control of Generative Models with Activation Transport (AcT)

Apple machine learning researchers have developed Activation Transport (AcT), a novel technique offering fine-grained control over large generative models, including LLMs and text-to-image diffusion models, without the resource-intensive training of RLHF or fine-tuning. AcT steers model activations using optimal transport theory, achieving modality-agnostic control with minimal computational overhead. Experiments demonstrate significant improvements in toxicity mitigation, truthfulness induction in LLMs, and stylistic control in image generation. AcT paves the way for safer and more reliable generative models.

Flix: Gracefully Handling Print Debugging

2025-09-25

Flix's designers faced a dilemma: how to enable efficient compiler optimizations while allowing developers to easily use print debugging? Directly using `println` breaks the type and effect system, causing compilation errors. The article explores two solutions: the first uses `unchecked_cast` to bypass effect system checks but results in code being optimized away; the second introduces a `Debug` effect, permitting debugging prints without modifying function signatures, and disabling the `Debug` effect in production. The final solution balances compiler optimization and developer experience.

Figma Sends Cease and Desist to AI Startup Lovable Over 'Dev Mode'

Design giant Figma has sent a cease-and-desist letter to Lovable, a rising AI no-code startup, over the use of the term "Dev Mode." While "dev mode" is a common term in software development, Figma holds a trademark for the shortcut. This isn't just a trademark dispute; it highlights the potential for larger tech companies to stifle competition. Lovable, using "vibe coding" to let users build with text prompts, directly challenges Figma's market. The outcome will be interesting, especially considering Lovable's seemingly unconcerned reaction.

Apple Declares 2018 Mac mini and iPhone 6s as Vintage

Apple updated its vintage product list, adding the 2018 Mac mini and iPhone 6s. This means these devices will receive more limited service and repairs. The iPhone 6s, initially launched in 2015, remained a budget option until 2018. The 2018 Mac mini was the last Intel-based Mac mini before Apple's transition to Apple silicon. A product is considered "vintage" five years after its last sale date and "obsolete" after seven years, at which point Apple ceases parts and repair provision.

Redefining 'e' with Pre-Calculus: An Intuitive Approach

2025-04-17

This article elegantly redefines the natural logarithm base 'e' using pre-calculus, rather than calculus. It leverages geometric intuition, explaining that all exponential curves (with positive real bases) are horizontal stretches of a single curve. By calculating the slope of the tangent line at x=0, it approximates 'e' and further proves that the tangent slope of eˣ is always equal to its y-value, mirroring the derivative concept in calculus. Finally, it visually demonstrates the equivalence of this definition with the compound interest limit, providing a more intuitive and accessible understanding of 'e'.

Hydrogen Buses: A Failing Experiment?

Multiple European cities have experimented with hydrogen buses, but the results have been disappointing. High manufacturing and operating costs, coupled with an unstable hydrogen supply chain, have led to many projects being scrapped or scaled back. Several cities have switched to more affordable battery-electric buses. While a few cities have achieved some success using industrial byproduct hydrogen or building their own green hydrogen production plants, these cases are difficult to replicate and face challenges such as hydrogen leaks. The EU continues to invest heavily in hydrogen projects, but their economic and environmental benefits are questionable. In the future, low-carbon hydrogen may play a role in specific industrial sectors, but its potential as a major transportation fuel is diminishing.

The Illusion of Theory in Large Programs: LLMs and the Limits of Code Comprehension

2025-04-28

Peter Naur's paper argues that the 'theory' of a large program isn't the code itself, but rather the deep understanding possessed by the programmers who built it. Using Ryle's analogy of a path, the code is the path, while understanding the program is like walking it. While LLMs can generate text that appears theoretically informed, this is merely surface-level; it lacks true comprehension. Naur emphasizes that understanding large programs requires continuous involvement in their development and maintenance—a knowledge that cannot be gained simply by reading code or documentation.

Broadband Lobby Fights Back Against State-Level Affordable Internet Bills

A California bill mandating $15 broadband plans with 100Mbps download and 20Mbps upload speeds has sparked a backlash from internet service providers (ISPs). ISP lobbying groups argue this, along with similar proposals in states like Connecticut, constitutes 'unnecessary anti-competitive regulation'. They're attempting to use federal preemption to block state-level laws, a strategy that failed previously. This is because the FCC, after eliminating net neutrality rules, lacks authority to regulate broadband pricing. Courts have ruled the FCC can't preempt state laws in areas it doesn't regulate. Despite this, ISPs persist, hoping for a future court ruling in their favor.

Apple's China Market Collapse: Nearly 50% Year-over-Year Drop

Apple's iPhone shipments in China plummeted nearly 50% year-over-year in March 2025, reaching a mere 1.89 million units. Domestic brands now control 92% of the market, leaving Apple with around 8% and fifth place. Huawei's resurgence, fueled by its own chips and HarmonyOS Next, has led the charge. A Chinese government subsidy program, offering a 15% refund on electronics under 6,000 yuan ($820), also hurts Apple, as the iPhone 16 starts just above that threshold. To combat the decline, Apple is reportedly cutting prices on some iPhone 16 Pro models ahead of the "618" shopping festival. Apple CEO Tim Cook acknowledged the revenue drop from Greater China, while analysts point to Apple's slower adoption of generative AI as another factor.
