Microcode in Intel’s 8087 floating-point chip: the scale instruction

🔥 Check out this must-read post from Hacker News 📖 📂 **Category**: ✅ **What You’ll Learn**: In the 1970s, floating-point arithmetic was a mess. Computer manufacturers had a dozen incompatible arithmetic standards. Moreover, floating-point systems were designed around hardware simplicity rather than mathematical rigor, leading to problems with numerical stability. This changed when Intel introduced the 8087 floating-point coprocessor chip in 1980, designed to be as accurate as possible, even in the corner cases. The 8087 became popular because it could be installed in the IBM PC, making floating-point operations up to 100 times faster in applications ranging from spreadsheets…

Fuck it, make it anyway

💥 Check out this must-read post from Hacker News 📖 📂 **Category**: ✅ **What You’ll Learn**: I kind of crashed out this week. Not in an explosive, dramatic way, but an implosion, a collapsing of the self, my resolve and motivation crumbling into the mush you get when you put tissue paper through the laundry. I’m doing better now, and I wanted to write down my thought process in case anyone else is going through the same thing, especially, probably, sadly, future me.The reason for this is, I guess, all too familiar for anyone in a creative field: surprise, it’s…

American College of Sports Medicine Position Stand. Resistance Training Prescription for Muscle Function, Hypertrophy, and Physical Performance in Healthy Adults: An Overview of Reviews

🚀 Discover this awesome post from Hacker News 📖 📂 **Category**: 💡 **What You’ll Learn**: Exercise is crucial for health throughout the human lifespan, and muscle strength and function are essential components of fitness. Resistance training (RT), also known as strength or weight training, is a specialized method of physical conditioning in which muscles are exercised by contracting against external resistance, such as free weights, machines, resistance bands, water, or body weight, through isometric, isotonic, or isokinetic actions, progressively increasing force output to improve muscular strength, power, endurance, and overall health and sports performance. The benefits of RT are being…

Retrospectively Reverse-Engineering Apple’s Neural Engine

🚀 Check out this must-read post from Hacker News 📖 📂 **Category**: 💡 **What You’ll Learn**: I stopped working on the reverse-engineered Apple Neural Engine (ANE) driver three years ago, upon a sad mini realization that the ANE block is just not that useful, and I could be doing more useful things, and moved onto upstreaming other, more useful, blocks. The ANE's architecture was too opinionated to build a general-purpose accelerator platform around it, and a linux driver effectively opening ANE hardware API access could not broaden the class of workloads it could do. Even macOS only regularly uses their…
