First of all, System administration does NOT simply involve going thru menu systems at whatever level, contrary to popular belief.
I know - our sysadmin's spend a lot of time fixing broken laser printers( empty toner cartridges and paper trays) running Ethernet cable everywhere, maintaining virus scanners, firewalls, running computer security/application courses, teaching computer network theory).
I do understand the difference between GUI programming (which I meant previously) and real-time systems programming with monitors/semaphores/shared memory/daemons/pipes etc... I should have been more specific.
He probably means that most application programming is simply connecting widgets together without much care about optimisation, plus writing scripts, with system administration simply involving going through menu systems at a high level.
While designing an ASIC chip/circuit board is going to require low-level programming and a great deal of thought into optimisation and timing.
Apart from your voice and data traffic, the 'mobile' part of your connection also keeps track of the signal strength from the nearest cell phone towers. This allows the operator to give an estimate of your location, the accuracy of which is dependent upon the number of towers within range.
Since each cell phone tower is going support hundreds of phone calls simultaneously, this requires a high-speed digital data link to the nearest trunk exchange, where the call can be routed to other telephone networks, as well as the operators accounting system.
Since the data is digital it can be multiplexed or diverted and split off in any direction. Particularly useful for voice-mail, three way calling and group conferences.
Your mobile phone is always in communication with the nearest cell phone tower, even if it isn't actively handling a telephone call.
There have been several cases where a suspect had been incriminated by the times and locations that a mobile phone has been used and switched off.
You should look at the example of the prairie dog - he build an underground nest with a lookout post, and there is enough space for four to five adult females.
There was another one I remember reading on slashdot where some guys managed to persuade another that it was perfectly safe to repeatedly type in his system password because it would only appear as ****'s to them.
That's why the manufacturing companies refer to the UK as "Treasure Island". Because the UK is an island, there is a financial disincentive for people to go into neighbouring countries and buy cheaper products there.
The only time such behaviour is profitable is when the taxes are high enough to offset the cost of transportation; in particular alcohol and tobacco products.
I'm not sure it is possible to pull this off. Isn't the north Atlantic cold at this time of year?
From this surface temperature map it would appear that if he swam at a latitude of 30 degrees North, the temperature is around 70 Fahrenheit or 21 Centigrade all the way to Spain. From Spain to South America it's even warmer (85 Fahrenheit/28 Centigrade). Up beside Norway, it's only 55 Fahreheit (12 Centigrade), so he would probably need a survival suit.
It was probably the fear of evolution into unemotional machines, world war, mutation from radiation, and the ability to replace parts of the human body with machines. The latter concept was greatly extended upon by the "Cybermen", who fought off disease and old age by replacing the failing parts of their bodies with robotics, until everything from their hearts to minds was machine. From HypnosInMedia
The Doctor's first and most persistent enemy. Created by the mad scientist Davros, they were the descendants of the Kaleds from the planet Skaros. When centuries of nuclear war caused mutations in the race, Davros encouraged the mutations and designed the travel shells they use. He also gave them their unstoppable thirst for conquest. Their chilling cry of "Exterminate!" was feared throughout the galaxy.
The Daleks would eventually come to realize that they were imperfect, mainly because of their many failures at conquering the galaxy, and they would seek out and eventually be led by their creator, Davros.
I can see the research work they did in university and it's always something very esoteric. I most certainly *do not* want them architecting major products.
That's the dilemma with doing a Ph.D. You are required to do three things:
1. Produce at least 2 or 3 papers during the duration of your stay. The last paper will typically be produced while your are writing up your thesis.
2. Produce a thesis demonstrating new, original and unique research.
The problem is that between (1) and (2), if you do anything that is useful to industry eg. a new algorithm, it will be immediately be adopted by application/hardware vendors, and you will have lost the originality of your project. In this time (six months), a startup will have formed, employed several graduates, constructed an application/plugin, and have been bought out by an existing company, all before you have gained your PhD.
So, the majority of PhD research projects have evolved to explore "safe areas" that aren't of immediate interest to industry, unless they are of truly new research. Either they make use of "big metal" systems that aren't accessible to the average company (supercomputing, particle physics, genomics), pure theory (formal verification), or something completely whacky (memory gobbling data structures).
And in order for a university lecturer to make it up to professor, he/she has to run a research lab which can take on as many postgraduates as possible. To give everyone space, each person is given an particular area of focus. For the first student to explore a new research area, this isn't too bad, but the following students will then have to split any offshoot research areas between them. (Much like how a company might employ one engineer to write an in-house application, then a year later employee three engineers to focus exclusively on different parts of the application; core libraries, visualisation, GUI).
RAM is a commodity, much like LCD displays, CPU's, and GPU's.
By itself, it isn't very useful, but when combined with other systems (desktops, laptops, PDA's, mobile phones, handheld consoles), it becomes a very useful item.
As with all commodities, the price will always go up whenever demand exceeds supply. And the suppliers will always try to achieve this; either by sophisticated marketing to boost demand (eg. the diamond market, the power generators warning of a shortage of electricity) or by matching reducing supply to match demand (OPEC, the RAM market).
Sun came out with a PCi card that allowed people to run Windows NT in an X-server application window, primarily for CAD users who wanted to read Windows E-mail.
And of course, there is Wine which allows Windows application to run on Linux.
So Microsoft are going to have to compete somehow.
I've seen this situation in the regular office world as well. It's amazing the amount of stuff that gets junked simply because one part has broken, and it's quicker to go across the street to buy a new item at the computer store, or to open a web-browser and make an online purchase, than it is too open the machine up and replace the broken component.
The most obvious example - my cousin had a portable CD-player that had crackly audio (the headphone socket had worn away). So she decided to throw out both the headphones and the player...
Or the computer with a broken video card - the maintenance company send a technician to replace the entire computer: desktop, keyboard, mouse and monitor.
My personal gripe is with headphones - usually it's the wire that goes first, while the speakers are working perfectly. Unfortunately, because it's a once piece component, I have to throw everything out. However, if the headphones had a socket for the wire (and the wire then became a patch cable), then I could just replace the wire.
Look up the specifications for any cruise liner Mercury project. There is enough redundancy for this never to happen. PROPULSION
The vessel is propelled by four MAN B&W L48/60 non-reversible, four-stroke engines. Two have an output of 9,450kW and two of 6,300kW at 500rpm. Each gearbox is additionally provided with a power take-off for a 5,200kW shaft generator for electric power supply during the voyage. Depending on the required ship's speed, different propulsion modes can be operated. The engines are connected to the Renk gearboxes via flexible Vulkan-Rato couplings. The engine speed is controlled by digital, redundant, freely programmable engine governors that work together.
The vessel has two controllable pitch propellers, three bow thrusters, two stern thrusters and two active rudders that are operated by a joystick. For the ship's propulsion and manoeuvring operations, an integrated redundant, computer-aided, decentralised system is used, which is connected via field bus to the automation system. Each propeller plant, transverse thruster and rudder has its own self-sufficient process station, connected by a redundant bus with the bridge station. For seakeeping, installed stabilizers are capable of reducing the ship's rolling motion by 90% at a speed of 18 knots.
Electric power is supplied by four MAN B&W, type 6L40/54 auxiliary diesel generator sets, as well as two shaft generators driven by a gearbox.

If you are a normal immigrant or a citizen, you don't have to worry about immediate deportation when your boss threatens to fire you.
But your boss still has the worry that you might work for one of their competitors, and/or that you take some company IP/know-how back with you.
There was a theory that carbon nanotubes would support Cooper pairs (if impurities were added).

Will names with lucky symbols be outbidded for?
I, for one, can't quite imagine how are they going to stop neutrinos from entering that space...
Just make sure all the cracks are covered by duct tape - lots and lots of it.
Am I the only one here that passed basic math? I could have *sworn* that screen was only rotated 90 degrees in the picture...
To get the screen to lie flat on the keyboard with screen visible in tablet mode, it's got to rotate 180 degrees from the standard foldup mode.
And as compromise there will be:
short = 48 bit
as two parties couldn't agree on whether a short int should be 32-bits or 64-bits, so they decide to half the difference.

The Judge appears weekly and passes judgement on smalltown disputes between colonists, bounty hunters, and off-world traders.
There was a discussion some while back from the navy guys about "the dangers of high pressure steam, gas cuts and broom handles".

Even better, we could give them human intelligence and maybe they could fight back against poachers as well :)

Have a look at the website Residential vessels, in particular the link covering Computer Systems. They have everything from multiple computer systems to a fibre-optic intranet connected by a satellite link.
From the website, a six month lease for a basic 250 foot unit is around $250 for a month, or lifetime for $8000.
