The Pentium contains a complicated circuit to multiply by three
this multiplier is a small part of the Pentium's floating-point multiplier circuit. In particular, the Pentium multiplies two 64-bit numbers using base-8 multiplication, which is faster than binary multiplication. However, multiplying by 3 needs to be handled as a special case. Moreover, since the rest of the multiplication process can't start until the multiplication by 3 finishes, this circuit must be very fast. If you've studied digital design, you may have heard of techniques such as carry lookahead, Kogge-Stone addition, and carry-select addition. I'll explain how the ×3 circuit combines all these techniques to maximize performance.
The downside to radix-8 multiplication is that multiplying by a number from 0 to 7 is much more complicated than multiplying by 0 or 1, which is almost trivial. Fortunately, there are some shortcuts. Note that multiplying by 2 is the same as shifting the number to the left by 1 bit position, which is very easy in hardware—you wire each bit one position to the left. Similarly, to multiply by 4, shift the multiplicand two bit positions to the left. Multiplying by 7 seems inconvenient, but there is a trick, known as Booth's multiplication algorithm. Instead of multiplying by 7, you add 8 times the number and subtract the number, ending up with 7 times the number. You might think this requires two steps, but the trick is to multiply by one more in the digit to the left, so you get the factor of 8 without an additional step. (A base-10 analogy is that if you want to multiply by 19, you can multiply by 20 and subtract the multiplicand.) Thus, you can get the ×7 by subtracting. Similarly, for a ×6 term, you can subtract a ×2 multiple and add ×8 in the next digit. Thus, the only difficult multiple is ×3. (What about ×5? If you can compute ×3, you can subtract that from ×8 to get ×5.) To summarize, the Pentium's radix-8 Booth's algorithm is a fast way to multiply, but it requires a special circuit to produce the ×3 multiple of the multiplicand.

Can White Men Finally Stop Complaining? - WSJ
For 50 years, we’ve been hearing from men who feel threatened by the gains of women and minorities. Now that the manosphere is in charge, the victim mentality has to go.
Racism and sexism are as old as time. But the “oppressed white man” trope is a relatively modern invention, with roots in the civil-rights and women’s-rights victories of the 1960s. Protests and lawsuits followed, with aggrieved white men turning the language of civil rights on its head. “Talk about rights; we’ve got no rights!” a crowd of white Detroit police officers chanted in 1975, protesting a court ruling in favor of the department’s relatively few Black and female officers. The TV character Archie Bunker, the oppressed white guy’s avatar, captured that spirit in a 1974 “All in the Family” episode, when he complained about a female colleague whose pay was equal to his: “What’s the point of a man working hard all his life, trying to get someplace, if all he’s gonna do is wind up equal?!”

The Fall of the USS Gettysburg | RealClearDefense
At around 0300, on Sunday, 22 December, the Aegis cruiser USS Gettysburg (CG 64) shot down an F/A-18F preparing to land on USS Harry S Truman (CVN 75) while operating in the Red Sea. The Carrier Strike Group to which each of these units was assigned was an element of the U.S.-led Operation Prosperity Guardian, assigned to protect Red Sea merchant traffic from Yemen-based Houthi attacks. First, we all need to understand that there is only one man who knows what happened on that day, and that is the commanding officer of Gettysburg. Apart from the F/A-18F crew, which possesses a very small but critical piece of the puzzle, everyone else is just an observer, a post-exercise armchair quarterback.
By the time that the Navy, writ large, understands all the errors and failures that contributed to this particular chain of events, a standard strategy may well have been enacted, i.e., “Nothing to see here, folks. Move along.” You see, the Navy doesn’t like to discuss “family business” with taxpayers, who may ask awkward, and potentially embarrassing, questions. It is much easier to pin the tail on one specific, commanding officer donkey.
