Submission + - Could gravity be evidence that the universe is a computer simulation? (theconversation.com)

loserhead writes: The Conversation published an article giving further evidence that none of us exist.

FTA: "Suppose the law of gravity is simply an echo of something more fundamental: a byproduct of the universe operating under a computer-like code...

It is a notion that seems like science fiction â" but one that is based in physics and evidence that the universe appears to be operating suspiciously like a computer simulation.

In digital technologies, right down to the apps in your phone and the world of cyberspace, efficiency is the key. Computers compact and restructure their data all the time to save memory and computer power. Maybe the same is taking place all over the universe?"

My laptop has absolutely no indicators other than a single one that lights white when it is charging and amber when the battery is critaclly low. With an SSD you can't even rely on the sound of the drive spinning to tell you it's doing something.

I use Glances to keep on top of memory and CPU useage and to monitor the tempurature sensors. I also run Wavemon to monitor network IO.

These two applications occupy the bottom half of my "Engineering" workspace (yes, my workspaces are Star Trek themed) and both can be run in an SSH session to see wtf is going on if the display becomes unresponsive.

More interesting though might be a labor claim that Best Buy might have against these employees

I read about this a couple of months ago but in the context of employees suing Best Buy because they were suffering PTSD due to the nature of the images they were being compelled to view on their customers' computers and their medical plan didn't cover it.

Submission + - Iron-age potters accidentally recorded Earth's magnetic field strength

Solandri writes: We've only been able to measure the Earth's magnetic field strength for about 2 centuries. During this time, there has been a gradual decline in the field strength. In recent years, the rate of decline seems to be accelerating, leading to some speculation that the Earth may be losing its magnetic field — a catastrophic possibility since the magnetic field is what protects life on Earth from dangerous solar radiation. Ferromagnetic particles in rocks provide a long-term history which tells us the poles have flipped numerous times. But uncertainties in dating the rocks prevents their use in understanding decade-scale magnetic field fluctuations.

Now a group of archeologists and geophysicists have come up with a novel way to produce decade-scale temporal measurements of the Earth's magnetic field strength from before the invention of the magnetometer. When iron-age potters fired their pottery in a kiln to harden it, it loosened tiny ferromagnetic particles in the clay. As the pottery cooled and these particles hardened, it captured a snapshot of the Earth's magnetic field. Crucially, the governments of that time required pottery used to collect taxed goods (e.g. a portion of olive oil sold) to be stamped with a royal seal. These seals changed over time as new kings ascended, or governments were completely replaced after invasion. Thus by cross-referencing the magnetic particles in the pottery with the seals, researchers were able to piece together a history of the Earth's magnetic field strength spanning from the 8th century BCE to the 2nd century BCE. Their findings show that large fluctuations in the magnetic field strength over a span of decades are normal.

But what does it have to do with my phones capability to record a call?

If you can hear it, you can record it.

I record most of my calls. At work I use a Nexxtech telephone recorder similar to this this. I plug the 3.5 mm jack in to my Tascam DR-07 digital recorder. When I place or receive a call I just press record then log the call details along with the file name when it ends.

If a call comes in on my cell that I want to record I ask the caller to wait while I put them on speakerphone then use the Tascam's built in mics to record the conversation.

If you don't have a stand-alone recorder, a laptop with built-in mic and/or audio input and something like Audacity will do nicely as well.

If your phone lacks the ability to record conversations, either because it doesn't have speakerphone capabilities or can not work with a device like the one I linked to above, I would replace the phone. Cordless phones can be problematic as they emit rf that can be picked up by the recorder but a cordless with speakerphone either on the base station or handset should work with a digital recorder with built-in mics.

The biggest challenge with recording calls is keeping track of all them so you can find the relevant one in the future. I hacked together a simple PHP/MySQL application I host on my personal site that I use to log calls but a spreadsheet works well too. It's also helpful to begin recordings with whatever detail you can provide prior to dialling or answering. That way you just have to listen to the first few seconds of your recording to find out what the call is about.

If the laws where you live prevent you from recording a conversation you are participating in I would say you have significantly bigger problems than your phone's hardware capabilities.

I keep written notes of meetings, I keep my old notebooks, I keep a (semi) daily journal, I archive emails, appointment calendars and task lists as well as text messages and all other forms of written communications. I see no reason why I should not be able to record any conversation I am part of. If a person asks me to not share what was talked about with others, the existence of a recording has no relevance to that. If I can remember it, there is a record.

As far as calls with companies go, I can't remember the last time a call to or from a business or government agency didn't include the disclaimer that "for quality control and training purposes, this call may be monitored or recorded." I always reply that it most certainly is.

In general I don't record personal calls with friends or my wife, since it's unlikely I will need a record of those calls in the future. But they *are* being recorded, of that I have no doubt. All calls are recorded by various agencies and companies. I have no control over that. What I can do is keep my own record of my calls, just in case the need ever arises for me to know what exactly was said.

As long as you take reasonable precautions to safeguard these recordings - as you would your written communications - I can not see why there would be a problem with it.
