Off the back of this she offered me a 24 hour study, and then strapped a cuff to my arm plumbed into a little device which I had to wear in a little caddy - the cuff would inflate every 30 minutes during the day and every 60 minutes during…

It’s now competitive with WSLtty on my machine. Details in the GitHub Issue. In 2009, I wrote about why MinTTY is the best terminal on Windows. Even today, that post is one of my most popular. MinTTY in 2009 Since then, the terminal situation on Windows has improved: Cygwin defaults to MinTTY; you no longer need to manually install it. Windows added PTY support, obviating the need for offscreen console window…
✨ Discover this awesome post from Hacker News 📖 📂 Category: 📌 Main takeaway: The standard Lanczos method for computing matrix functions has a brutal memory requirement: storing an n×kn \times kn×k basis matrix that grows with every iteration. For a 500.000500.000500.000-variable problem needing 100010001000 iterations, that’s roughly 4 GB just for the basis. In this post, we will explore one of the most straightforward solutions to this problem: a two-pass variant of the Lanczos algorithm that only requires O(n)O(n)O(n) memory at the cost of doubling the number of matrix-vector products. The surprising part is that when implemented carefully, the…

These protections build on Mozilla’s long-term goal of building a healthier, transparent and privacy-preserving web ecosystem. Fingerprinting builds a secret digital ID of you by collecting subtle details of your setup — ranging from your time zone to your operating system settings — that together create a “fingerprint” identifiable across…

Average incomes were 22 percent lower than the United States at the start of the war; by the end that gap had grown to 75 percent. These economies were different in kind, too. In 1950, for every farmer in America there were 2.7 manufacturing workers, compared to just 1.3 in Germany and 0.92 in France.11.

Credit: IOP Publishing A new study published in Environmental Research Letters finds that continued growth in artificial intelligence (AI) use across the United States could add approximately 900,000 tons of CO₂ annually. This is not a small amount but equates to a relatively minor increase when viewed in the context of nationwide emissions. While AI adoption is expected to boost productivity and economic output, researchers note that…
