Time is Mone…. not so fast…

On the occasion of Italian physicists findings about the nature of time I have come to a unique understanding of an age old saying. Knowing now… that it must change, Time = Money.

They proved that time is an emergent phenomena of quantum entangled particles, so quite literally…

time = Quantum Entanglement

I don’t think the food store will take that as a substitute for money though…

Some background, in 1983 two physicists managed to mathematically and theoretically link Quantum mechanics and the standard model of physics. They did this by exploiting Quantum entanglement. There was one problem with their novel approach… the variable “t” (or Time) was not part of the solution.

Which… as we all know… there is never enough time, but its not completely non-existent. 🙂

Entanglement is the exotic property in which two quantum particles share the same existence, even though they are physically separated.  (ie. If two tennis balls on different sides of our galaxy are entangled, when I change the state of one of them, say spin it left, the other should instantaneously spin to the left… this is an oversimplification, but it illustrates the point).

As such the Italian scientists devised an experiment to test some of the conclusions and theoretical properties of the Page & Wooters Theory from 1983. I won’t go into the details, go here if you are interested, but one aspect of the theory is that time is an emergent phenomenon from entangled particles and is only detectable to an observer inside the same Universe as the particles (as opposed to an observer outside the universe, for which time is different).

Yeah… just let that sink in for a moment.

Anyhow, the Italians proved this part of the theory was correct. Which strongly indicates the 1983 theory is correct… and happens to mean that time really is created by quantum entanglement.

 

Hash will likely get settled…

You may have heard. China is working on a PC operating system to replace Microsoft Windows. (Makes you wonder about the Anti-Trust raids they conducted recently).

Rumors are rife, no one knows if its a resurrection of the ill-fated Red Flag Linux or some Windows type derivative.

I applaud China and wish them the greatest success.

Why you ask.

If its a complete ground up build of some windows derivative, and they think building a secure OS is an easy task, they will find out differently.

The CIA, NSA, Anonymous and everyone with a problem with China or totalitarian governments in general will have an absolute field day with this.

I’m even somewhat looking forward to getting a copy myself for a tear down.

In the end, the hostile traffic they are spewing at everyone from their cyber war program is likely to be unmercifully returned in spades and the best part, reciprocity is likely to be difficult, that is, some flaws will no longer be symmetric (ie. what is used against them, can’t be turned on anyone else because they will be unique to the new OS).

I’m betting they will get their hash settled for at least a decade.

Also, realize, they tried this once before, Linux aficionado’s may recall China’s last attempt, Red Flag Linux, whose supporting company that created the distro, went out of business and the distro itself went no where.

So if the new OS is based on Red Flag… just more of the same, nothing really new to see here and they are just in the same boat as all other Linux users. But I’m betting Chinese civil service is just as stuck as everyone else’s, patches are unlikely to be timely. It might also just be a bluff or ploy because the U.S. indicted 5 PLA Army officers for cyber-espionage last May which set off China on a tear of harassing US-Based companies (Google, Microsoft, etc).

At the very least, this should make things interesting and difficult for IT people in China for a few years. To use their own curse, “May you live in interesting times new unnamed Chinese OS”.

Let the games begin.

Parallella Online and Being Tested..

Finally, after hunting for a decent power supply and attempting to navigate through Adapteva’s somewhat, detail lacking, documentation, my Parallella’s are finally churning away.

In picture, Rho, the first of two nodes, running the Blobubska real-time ray-tracing demo.

Parallella Running Blobubska Demo

First thoughts, its a little sluggish, but realize, any similar OpenGL demo would be operating on a graphics card like a nVidia Tesla with 512 Cores while this little puppy is doing a respectable job on only 16 Epiphany cores. I am eager to see how the 64-Core Parallella handles the same demo when Adapteva finally releases it.

My goal of this test, was mostly to measure the operating temperature performance with a medium load. Adapteva suggests, anything below 70C is good.

Since this is essentially a Rev A board, its lacking in some features that the Rev P boards have, namely a heat sink slab for both the Zynq FPGA and the Epiphany-16, I have modified the setup slightly, I added my own heat sink to the Epiphany chip and I placed a 5V fan to blow across both heat sinks.

The good news, the improvements worked better then expected. Its been running all day on the Blobubska demo and hasn’t gotten above 59.1C (sitting in an already hot office). As well, system load has maxed at 0.31 (as compared to running the demo in HostOnly mode [i.e. runs without the Epiphany chip] at a load of 1.5 and terribly sluggish video by comparison). Heat and load monitor below…

What was funny, since I am the paranoid security type, I always keep a close eye on /var/log/auth.log to see if anyone is banging on the box. Between the Parallella and my Raspberry Pi Model B+, I’ve had to block 7 networks from China, one from Denmark and one from Spain.

Damn crackers picking on my poor little computers.
