Oggi le persone chiedono ai propri rappresentanti politici, ai propri leader, la rimozione
Non la fiducia, lo sforzo caparbio, la lotta per migliorare, ma la rimozione
La rimozione dei propri problemi, dalle difficoltΓ , dai fastidi della vitaΓ questo il vero problema
Γ questo che vuol dire vivere, in modo del tutto errato e totalmente sbiellato, la vita
Vivere una fantasia dorata e rosa da film
Essere nel paradigma allucinato del consumismo

Reverse-Engineering the Intel 8087 Stack Circuitry
Although something thatβs taken for granted these days, the ability to perform floating-point operations in hardware was, for the longest time, something reserved for people with big wallets. This began to change around the time that Intel released the 8087 FPU coprocessor in 1980, featuring hardware support for floating-point arithmetic at a blistering 50 KFLOPS. Notably, the 8087 uses a stack-based architecture, a major departure from existing FPUs. Recently [Ken Shirriff] took a literal closer look at this stack circuitry to see what it looks like and how it works.
Nearly half of the 8087βs die is taken up by the microcode frontend and bus controller, with a block containing constants like Ο alongside the FP calculation-processing datapath section taking up much of the rest. Nestled along the side are the eight registers and the stack controller. At 80 bits per FP number, the required registers and related were pretty sizeable for the era, especially when you consider that the roughly 60,000 transistors in the 8087 were paired alongside the 29,000 transistors in the 16-bit 8086.
Each of the 8087βs registers is selected by the decoded instructions via a lot of wiring that can still be fairly easily traced despite the FPUβs die being larger than the CPU it accompanied. As for the unique stack-based register approach, this turned out to be mostly a hindrance, and the reason why the x87 FP instructions in the x86 ISA are still quite maligned today. Yet with careful use, providing a big boost over traditional code, this made it a success by that benchmark, even if MMX, SSE, and others reverted to a stackless design.

Proprietary: let's call the web browser some colonial name like Explorer, Safari
FLOSS: the menu entry for the web browser must read Web Browser because otherwise the user will be confused about what it does.

@Gina hi Gina, Iβm a Canberra based Red Hatter and also on the Linux Australia council (for at least the next month or so).
Happy to help if I can.
