First time using a banneton, beautiful shape. Tried a different knead style too. Rye-AP mix

Tried to make something more sandwich-y. 4 hour warm proof with wheat, rye, and corn flours. A bit dense, but not bad.

Magic Division -- Or Division by Integer Multiplication

+ +

I noticed something strange in the assembly generated when compiling a program + using gcc an optimization turned off. Here it is in Figure 1 + (though using optimization level 3 just to simplify, but it still shows in level 0). + In this generated assembly, we see instead of using the div operator, + something strange is going on with the number 1717986919 and shifting. My first + attempts at searching for this phenomenon online were not helpful. The first result + for the number was on Amazon as a book identifier. This number also shows up on + stack overflow, however it is no more helpful. No one on the post is talking about + why this number is in the generated code (or perhaps they all know this arcane + secret and don’t wish share). Eventually, I found out what was going on. Even + with no optimization, the compiler prefers to generate multiplication operator + over the division operator. +

+

We will consider unsigned integer division first. Let + d + be some constant divisor, and n + our numerator (for now let’s make n + a multiple of d). We will assume + integers are 32 bits. In order to computer + n/d, + first we need to know the values l + and i where + d = l2i. + So to begin out division, we can shift n + by i bits. Now we must divide this result + be l. Since + l will be odd, there exists some + inverse of l, called + j where
+ lj = 1(mod 232)
+ So for any number x, + x/l = (xj)/(lj)=xj. + So now all that is left after the shift is to multiply by + j, and we will + have computed n/d.

+

Dealing with remainder can go pretty in depth, and I recommend + reading the chapter in Hacker’s Delight about this topic + [1]. Another write up can be found + in the MSDN blog archive [2]. +
