Reader Daniel Hooper asks the natural question: just why is RAM so much slower than registers?

How I Got a 2x Speedup With One Line of Code
If you had asked me whether or not it was possible to get a 2x speedup for my LazySorted project by adding a single line of code, I would have told you "No way, substantial speedups can really only come from algorithm changes." But surprisingly, I was able to do so by adding a single line using the __builtin_prefetch…

Some Notes About Time
This is a trade-off: you can't represent a leap second, and your time is guaranteed to go backwards. On the other hand, every day has exactly 86,400 seconds, and you don't need a table of all previous and future leap seconds in order to format Unix time as human-preferred hours-minutes-seconds.

Why Do Companies Still Use Microsoft Windows For Displays?
As I was exiting Oxford Railway Station, I glanced at this screen showing the bus departure times. Notice anything odd about it? sigh Yet again someone has shoehorned Microsoft Windows into a product it is completely unsuitable for. Why does a screen which displays a fairly basic set of information need to be running…

Knossos: Redis and Linearizability
A few weeks ago I criticized a proposal by Antirez for a hypothetical linearizable system built on top of Redis WAIT and a strong coordinator. I showed that the coordinator he suggested was physically impossible to build, and that anybody who tried to actually implement that design would run into serious problems. I…
