Our eighth generation TPUs: two chips for the agentic era

https://cloud.google.com/blog/products/compute/tpu-8t-and-tp... The culmination of a decade of development, TPU 8t and TPU 8i are custom-engineered to power the next generation of supercomputing with efficiency and scale. Google is launching its eighth-generation Tensor Processor Units, featuring two specialized chips: the TPU 8t for massive model training and the TPU 8i for high-speed inference. These chips are purpose-built to handle the complex, iterative demands of AI agents while delivering significant gains in power efficiency and performance. You can request more information now to prepare for their general availability later this year. Google’s new eighth generation TPUs, TPU 8t and 8i, power the next era of AI. The TPU 8t is a training powerhouse built to speed up complex model development. The TPU 8i specializes in low-latency inference to support fast, collaborative AI agents. Both chips use custom hardware to deliver better performance and energy efficiency than before. These new systems will be available later this year to help scale your AI workloads.

"I already felt that gemini 3 proved what is possible if you train a model for efficiency. If I had to guess the pro and flash variants are 5x to 10x smaller than opus and gpt-5 class models. They produce drastically lower amount of tokens to solve a problem, but they haven't seem"

3.4M Solar Panels

Benchmarks & Tips for Big Data, Hadoop, AWS, Google Cloud, PostgreSQL, Spark, Python & More... In October, I reviewed the Ground-Mounted Solar Energy in the United States (GM-SEUS) dataset. This dataset attempted to outline the majority of solar farm arrays and panels across the US. Version 1 of this dataset contained 2.9M panels. On Monday, version 2 of this dataset was released and now contains more than 3.4M panels. In addition to the panels and arrays being refreshed, there is a new rooftop array dataset. In this post, I'll review v2 of the GM-SEUS dataset.

"We're off grid and have 7kw of panels, and 40kwh of 48v lithium batteries, with a generator for backup, which is rarely used since we are frugal with electricity and switch everything off when not in use. I set it all up myself, and while it is not trivial, it's not difficult eit"

Treetops glowing during storms captured on film for first time

Penn State experts in meteorology and atmospheric science made their way down the nation’s eastern coast in June 2024 in search of corona discharges, a long-hypothesized atmospheric weather phenomenon where miniscule pulses of electricity dance at the tips of tree leaves, causing the canopy to glow in the ultraviolet (UV). They found them and captured the phenomenon on film for the first time. The positive, left, and negative corona discharges are shown on a spruce branch in a nearly pitch-black environment of a meteorology and atmospheric sciences lab at Penn State. Credit: William Brune / Penn State . Creative Commons UNIVERSITY PARK — In a converted 2013 Toyota Sienna affixed with a hand-built telescopic weather device protruding from the roof, Penn State experts in meteorology and atmospheric science made their way down the nation’s eastern coast in June 2024 in search of Florida’s famed near-daily summer thunderstorms. They were hoping to catch corona discharges, a long-hypothesized atmospheric weather phenomenon where miniscule pulses of electricity dance at the tips of tree leaves, causing the canopy to glow in the ultraviolet (UV). For more than 70 years, scientists have suspected treetops might emit these corona electrical discharges because of odd electric field activity in and over forests during storms, yet they have never been documented outside the lab.

"There is in fact no photograph of treetops glowing. There is a digital UV-wavelength video of the corona, and a visible-wavelength video of the trees. The paper [1] contains a sole picture with tiny circles indicating where the UV-video detected corona events, overlaid over a fra"
