Latency lags bandwidth. Not just by a constant factor, either. Over time, bandwidth increases with the square of latency.
Classic computer engineering maxim. It’s held true for at least the last 35-40 years, across network, disk, memory, CPU. Patterson’s 2004 article is a classic. It’s had a deep impact on me; I still think about it regularly.
“The time has come,” the Walrus said,
“To talk of many things:
Of shoes—and ships—and sealing-wax—
Of cabbages—and kings—
And why the sea is boiling hot—
And whether pigs have wings.”
Credit card companies charge merchant fees of 1.5-3%. They transfer much of that directly to card holders as 1-4% cash back. Merchants generally charge the same prices for credit card vs cash. The result seems to be a small but universal penalty on people who pay with cash. 😢

Technology is amazing! It’s solved almost all of the problems that it caused in the first place.

Raymond T. Lahar
This Memorial Day weekend I’m thinking about my grandfather, Raymond T. Lahar (middle), and rereading his memoirs. He fought in World War II, in the European and North African theaters, Company K, 142nd Infantry, 36th Division, 1942-1945.
In late 1944, his company crossed the Vosges Mountains in eastern France on a mission to establish contact and supply lines with the Second Battallion. After hours of marching, they came to a field, started across, and immediately took direct machine gun fire. Ray was hit in the leg. He could barely walk, but still managed to help drag the rest of his company to cover and safety where medics could tend to them.
That was Ray’s last patrol. As one of his men, Sergeant Roy Christensen, put it: “You’ve got a beauty here. You’re going back to the States for sure. It’s a white foxhole for you.” Surgeons had to remove three inches from his left leg. He walked with a platform shoe and a cane for the rest of his life.
Ray was later awarded three Purple Hearts, the French Croix de Guerre, the Distinguished Service Cross, and 12 other medals. He was honorably discharged on June 15, 1948 with the rank of Major.
Thank you for everything, Grandpa.
