Does anyone know what are the physical limitations of highspeed ethernet? I mean at some point doesn't it become impossible to move electrons or modulate data any faster?
Very roughly, at one terahertz you can transmit one terabit. Now whats the frequency of an XRay laser expressed in hertz?
My local hospital has stopped giving me CT scans because I've had so many in the past (out of necessity) that they don't want to fry me any more than necessary.
From what I understand, Android is a Linux kernel with a Java based userland. So either you wait for an appropriate solution to appear, or you install a real Linux distribution and install... MythTV.
Unix userland comes from netbsd so that they don't have to mess with GPLv3. Java is more like a presentation layer.
I think the Chinese copycat manufacturers have some good ideas but their execution, especially their engineering, is nowhere close to American, Japanese, or Korean standards.
The Taiwanese made the eeepc. Their engineers are top notch.
Camouflage for the skin. Couple it with a camera to get an idea of background textures.
Incidently the audio on one of those pages was creeping me out. I'm sitting here listening to Neil Young and suddenly I get these creepy sound effects over the top. I had to hunt around through workspaces and tabs to find the source.
I need you
To let me know
that there's a heartbeat
Let it pound and pound
And I'll be
flying like a free bird
And you need me
Like ugly needs a mirror
And day by day
This horizon's getting clearer
Bob Heinlein seemed to know so much about L Ron Hubbard. It was his bet with Hubbard which initiated Scientology. I always wondered if they could actually be the same person, of if Hubbard was an invention of Heinlein.
My seven year old son didn't write the code which earns money for both of us. If I died he would still benefit from my pay, insurance, etc. Copyright lasts a long time by comparison, but writers earn their money at a slow rate. A month for me may equate to ten years for an author.
if the speed of traffic is 80 mph and the speed limit is 65 mph, which do they use?
You can't have many speed cameras where you live. If the limit here is 60km/h the average speed of traffic will be very close to that figure, but the vehicles at 70 will be offset by the vehicles at 50.
Its been a while now but I am pretty sure the travel time displays I worked on (different from the system I talked about up the page) were set up to never display a travel time which would involve breaking the speed limit. But when you calculate speeds of lots of vehicles and average them you hardly ever get an average over the limit anyway.
I remember once the freeway to the airport was closed due to a crash. When traffic started to move the profile looked like this:
0 0
160 1
0 0
0 0
90 15
80 20
70 30
Every line is 500 metres of road. Forward is up. The left column is average speed. The right column is the vehicle count. Clearly somebody with a porsche was late for a flight.
They could just get a boat but the problem would still be running a line to it. Since they have so much money I recommend they build a huge spindle in high Earth orbit, right near the rastafarian outpost.
A roundabout is just an application of "give way to the right" (or left in a drive on the right country). We could save a lot of Give Way signs and space for roundabouts if drivers were taught to use that rule.
Traffic signals are best used when you need to give some time to a low traffic road where it crosses a high traffic road. We have a few roundabouts here in Melbourne which are pseudo signalised during peak times. A long queue on an approach triggers a pedestrian crossing on the approach to the right, creating a gap in the traffic.
The system I worked on had configured in Link Plans which are designed by engineers, taking into account speed limits, distance between traffic signals, etc. Heuristics are used to select the LP to be used for particular set of intersections. Within the LP other heuristics are used to vary the behaviour of signals across a region. For example an increase in the Degree of Saturation will result in an increase in Cycle Time. DS is how dense the traffic is. Cycle Time is the time a signal controller takes to go through all its states.
A voting algorithm is used whereby intersetion controllers submit data to a regional controller. They vote to select parameters which are applied to all the signals in the region. I have seen what happens to peak time traffic when the regional controller was down (because I was working on it) and it is not a pretty sight.
I used to work on a traffic signal system in Australia. At one point we hosted an experimental system from (I think) the CSIRO which displayed the speed you would have to travel at get a green at the next intersection. The problem with that was that it gave really bad, but accurate advice, like travel at 12km/h or 80km/h. This is where the limit is 60. So they changed it to only display speeds below and close to the limit and then it was even more useless.
The actual algorithms which determined the timing of the signals was hand assembled by traffic engineers in 12 bit PDP/11 machine code, so it was impossible to know exactly how it worked.
Maybe that system was intelligent. It certainly had a lot of emergent properties.

What are channel9 complaining about... More people having access to their programming? Surely that's a good thing
Not if they don't sit down and watch the advertisements.

MRI doesn't do the job?
I think you just equated taiwan and mainland china
No, I equated them with the USA, Japan, and Korea.

He has so many things wrong with him that they may conspire to keep alive indefinitely. Maybe Stephen Hawking is how we will all wind up.
Yea but be careful to regulate the feedback because you don't want that sucker to get away from you!

What we are seeing here is an evolution of technology, where less adapted technologies are replaced by more adapted technologies.
Looks more like it is being Intelligently Designed.
Its just how many humans aggregate. Just like how gravity is how some kinds of matter aggregate.

Yeah it was called ADVISE. Had a nice little 19 inch rack of gear in a cabin in Blackburn. Probably still there for all I know.

They could find a dogy government to host them but the bullet percentage is pretty high.

600000 per month? Watch that comma.

Or they could just approach MS. MS would gladly provide support for the bragging rights that the DA is using their OS.
Perhaps not, if China gets pissed off about it.
