How much do electric car batteries degrade?
It’s always the battery in my mobile phone that gives up on me first. After just a few years, it can barely make it through the day without getting another charge. Most electric cars have the same types of batteries — usually lithium-ion — so the assumption is that they degrade just as quickly. This […]
TREAD: Token Routing for Efficient Architecture-Agnostic Diffusion Training
Abstract:Diffusion models have emerged as the mainstream approach for visual generation. However, these models typically suffer from sample inefficiency and high training costs. Consequently, methods for efficient finetuning, inference and personalization were quickly adopted by the community. However, training these models in the first place remains very costly. While several recent approaches – including masking, […]
Left to Right Programming: Programs Should Be Valid as They Are Typed
2025-08-17 Programs Should Be Valid as They Are Typed I don’t like Python’s list comprehensions: text = “apple banana cherryndog emu fox” words_on_lines = [line.split() for line in text.splitlines()] Don’t get me wrong, declarative programming is good. However, this syntax has poor ergonomics. Your editor can’t help you out as you write it. To see […]

We are taking steps to harden our infrastructure and operational security. The work of securing humanity’s legacy is worth fighting for. Since we started in 2022, we have liberated tens of millions of books, […]
Who Invented Backpropagation?
Efficient backpropagation (BP) is central to the ongoing Neural Network (NN) ReNNaissance and “Deep Learning.” Who invented it? BP’s modern version (also called the reverse mode of automatic differentiation) was first published in 1970 by Finnish master student Seppo Linnainmaa [BP1] [R7]. In 2020, we celebrated BP’s half-century anniversary! A precursor of BP was published […]
The Road That Killed Legend Jenkins Was Working as Designed
On May 27, 2025, two brothers in Gastonia, North Carolina, asked their dad if they could walk to the neighborhood Food Lion and Subway. It was less than ten minutes from their apartment. Their dad hesitated. He and his wife are protective parents. But he agreed, on the condition that the boys stay on the […]
The Weight of a Cell
Ella Watkins-Dulaney Microbes are so small that tens of thousands could fit in the space of the period at the end of this sentence. And yet, for two of the most widely studied kinds — S. cerevisiae and E. coli — we know their weight with remarkable precision: A single yeast cell weighs about 100 […]
