Simulated Time

by

If the Universe were a big simulation running on a super fast computer built by an advanced civilization, it would be possible, in theory, to determine if this were the case by coming up with a system to detect an outside of the Universe time reference.

A simulated system, running on a virtual computer, will have an internal clock whereby it marks time.

If that simulated system has the ability to detect a time reference that is external to the simulation, the simulation can not only conclusively prove that it is a simulation but also at what speed the simulation is occuring.

When I say “time reference” it does not need to be a clock as you and I would understand it.

The time reference could be the orbits of electrons, or the radioactive decay of a particle.

You may think you’re being original, but you ain’t.

Read – Complete Spectrum Rom Disassembly

by

Today I finished reading “Complete Spectrum Rom Disassembly” by Ian Logan

Tons of useful information. Took a while to make notes and insert post-its in the appropriate places.

What the hell people do to put notes in their books before post-its?

Read – The Art of Computer Programming: Volume 3: Sorting and Searching

by

Today I finished reading “The Art of Computer Programming: Volume 3: Sorting and Searching” by Donald Ervin Knuth

Aaannddd… I’m done.

All three volumes of a series of programming books that I am sure people will describe as “classic.”

This volume took me a long time to work my way through. I think I read about 30 other books in parallel whilst I was doing all the examples.

I have read every book in this series cover-to-cover.

And I have implemented all but two of the algorithms in BASIC, 6502 and Z80.

Please God, don’t let there be a fourth volume.

I’ve suddenly become very productive today because I seem to have run out of things to do that aren’t anything to do with my job.

Read – Dungeons and Dragons: Expert Set

by

Today I finished reading “Dungeons and Dragons: Expert Set” by David Zeb Cook

Sat down and read the rule books cover-to-cover rather than the “dipping in to” knowledge I sort of picked up through osmosis and playing the game alongside other people.
