You can't grow cool-climate plants in hot climates

news.ycombinator.com Joey Santore 2025-12-11 02:38:00

Since moving to Deep South Texas 4 years ago I've come to realize that many plants I used to love growing in the cool mild maritime climate of the SF bay area are impossible to grow where I live. This is not just because of the high daytime heat. It's not as simple as that. Specifically, it is the high heat during the night (and those warm nights are a direct result of the humidity) that causes cool-climate and cool-season plants to eventually die here.

Writing Speed-of-Light Flash Attention for 5090 in CUDA C++

In this post, I will walkthrough how I learned to implement Flash Attention for 5090 in CUDA C++. The main objective is to learn writing attention in CUDA C++, since many features are not available in Triton, such as MXFP8 / NVFP4 MMA for sm120. I also feel this is a natural next step after learning about matmul kernels. Lastly, there are many excellent blogposts on writing fast matmul kernels, but there is none for attention.

The Trump administration’s big Intel investment comes from already awarded grants

Intel officially announced an agreement with President Donald Trump’s administration on Friday afternoon, following Trump’s statement that the government would be taking a 10% stake in the struggling chipmaker. While Intel says the government is making an “$8.9 billion investment in Intel common stock,” the administration does not appear to be committing new funds. Instead, it’s simply making good on what Intel described as “grants previously awarded, but not yet paid, to Intel.” Specifically,

Lightning declines over shipping lanes following regulation of sulfur emissions

As it turns out, the lightning really is responding to the ships, or rather the tiny particles they emit.
