As someone has already said, this would more than likely be installed onto a system that an image is then made from. This would be done using a tool called "Sysprep" which brings the system back to a just installed date, with all the applications still installed that were done before the sysprep tool was used.
Once this image is created, a new PC can be "installed" in less than 5 minutes with a 500GB image over a USB2 interface (yes, I've done this many times!)
Re: A third Tesla went up in flames this week
All three have been due to accidents.
One encountered a large piece of metal that apparently if it was a regular car would have penetrated the passenger cabin and killed the driver.
One drove across a roundabout, through a wall and collided with a tree. http://jalopnik.com/another-tesla-model-s-caught-fire-after-a-crash-in-mexi-1453376349
The latest incident is being investigated but by all accounts was involved in a non-standard incident.
So at least two have been due to extreme external influences.
Does anyone actually proof read these articles? Next spring's LTS release is 14.04.
A company that has filed for Chapter 11 is still available for trading on the stock market.
This is a trader fail, as the Q denotes a company that has filed for bankruptcy.
Re: Lithium + water?
There is no pure lithium in a Li-Ion battery. In thermal runaway all the constituents for fire are within the cell. CO2 or foam will have no effect. Water is the most effective extinguishant - the more the better - to kill the heat (the only thing you can control in a Li-Ion fire)
Ok, so Tesla have stated that the fire started in the battery pack. The most likely cause of this is due to the metal debris the driver said he ran over punctured a cell and caused a short circuit.
Now, this is a Lithium-Ion battery pack, which contains no raw lithium metal, and hence is not reactive to water.
Conventional fire training states that for an electrical fire, do not use water. In the case of a Li-Ion fire, this is not the case. Once the cell goes into thermal runaway, all the ingredients for the fire (Fuel, oxygen and heat) are in the cell. using CO2 or foam will have no effect (these are used to remove an external source of oxygen from the fire).
It has been stated that the initial use of water was not effective. Looking at the video the fire seems to have spread beyond the batteries, so there is likely to be an electrical fire outside the battery, plus whatever other flammables are there. At this point they used dry extinguishers, smashed through the battery and at that point (which this article does not mention) water was used on the cells to finally put out the source of the fire. It seems to me that the fire department on site had the proper knowledge and training to deal with the fire.
No-one was injured and the driver evacuated the vehicle safely. Any artificially powered vehicle that suffers damage in the wrong place will catch fire. There are numerous vehicle fires on our roads (and race tracks) every year, and none of these have this kind of effect on the stock price of that company. Hopefully the post-mortem reports will bring market confidence back to Tesla.
Breakaway Unit To Terminate Payload Lift Under Gravity
Not the first time that acronym has been used - different definition of course! :-D
Considering this was posted on the BBC website on the 31st of march, and there are US articles before the BBC one, not an April fool.
OK, so the sub-headline isn't technically incorrect..
....as this IS the first mission where the mission objective is to re-supply the ISS. The last Dragon capsule launch was the first private cargo vessel to dock with the ISS, and did carry with it some supplies.
Re: Wait a second...
Well, the satellites do tend to "roll out" from the integration hanger, where they are bolted to the rocket , to the launch pad...
The GPS orbit is around 20,200km in what is known as Medium Earth Orbit (MEO). The European Galileo system is in an orbit of around 23,222km, the Russian GLONASS system is at 19,100km and the Chinese Compass system has an interesting mix of GEO, MEO and HEO (inclined orbit at GEO altitude) satellites.
The main uses of satellites in LEO are Science based (weather, ice coverage analysis, ionosphere, ISS) and Earth Observation.
The problem with LEO broadband is it's not a viable option. The satellite is orbiting once every 90 minutes or so, with a pass lasting a maximum of 15 minutes. As for your dish, it would not be a static dish and would have to track the satellite(s).
Now you could have a constellation of satellites, but to be able to have a continuous connection you'd be looking at a huge amount of satellites. For example a constellation of 5 satellites can guarantee a point on the earth covered once every 24 hours.
The only viable use for LEO based internet is a store and forward service, which terminal based radio hams have been using some of the LEO satellites for since the 80's.
Re: What the fu..
According to my math, she's being paid over the minimum wage.
At 19, her minumum wage is £4.98. As she works between 30 and 35 hours a week, she would be earning £174.30 max if she was on minimum wage. Ergo, she must be on more than that if her average is £180.
Re: Not the first time
Erm, I think you'll find that the PC USB port will adhere to the USB standard. USB 2 according to the specs will supply up to 500mA. USB 3 will supply up to 900mA. The power adaptor for the ipad supplies up to 2A. So even if you have a USB 3 port, that is still less than half the power of the ipad charger.
A lot of the tech in SSTL satellites has been consumer grade electronics:-
Re: Bit surprising
Not exactly true. The orbits most of SSTL craft fly in is Low Earth Orbit (LEO) with an altitude of around 700km. This orbit is relatively benign. You only need to start looking to used rad-hard components in higher orbits (MEO or beyond)
Intel 368 processors have been used successfully in this orbit, with missions that exceed 4 years service.
I'm sure you can search for other instances of the use of this processor, and longer mission lifetimes than this.
Re: "even if "six-tenths of a kilometre" still has a ring of old school about it."
The most common abbreviation for km is Klicks. So they could have referred to the distance as "Point 6 of a klick" downrange..
Re: And then there is the weather
You design and build a decent enough vehicle, then weather will not stop a launch. I have only heard on one launch from Baikonur scubbed due to adverse weather conditions, and that was due to high winds. Cloud, rain, snow they'll launch whatever the weather. http://www.universetoday.com/90939/soyuz-launches-to-station-amid-swirling-snowy-spectacular/ and that was a manned launch!
Considering satellites in low earth orbit (600 - 800 km) have transmitters with an output of a few hundred milliwatts, then 2W at 50-60km will go a long way!
The even dafter thing is, I can see the US Patent Office granting this patent!
For those that have Garmin sat navs, there is a way of getting openstreetmap maps onto your device:-
Jay Leno's "jet" bike
Jay Leno told a story about his turbo jet helicopter engine powered bike. At a stop light, a car driver kept creeping up his tailpipe as Jay was trying to maintain a space between them. When the light turned green and he pulled away, he noticed the car had a slightly melted front fender.
Seems this process is on xbox too. EA have this in their new titles on both formats.
There's a difference between patents protecting real technological innovation and patents protecting rounded corners. From what I have read about the Galaxy Tab argument is that it looks a bit like an ipad.
No doubt someone who has read the whole argument will point out it's a bit more than that, but there still seem to be a lot of pointless patents out there. (Geddit?) :-D
Not a typical RC control system
There are boxy aircraft with small wings that do fly (apologies, a name doesn't come to mind right now) mostly light aircraft. As long as the wings provide enough lift, the lack of aerodynamic shape doesn't matter.
If you went and looked at the specs -
Wingspan - 67 inches. (Hardly tiny)
Length - 72 inches
Ths massive batteries - look at the images, there are two compartments just behind the nose that house the two 22v 5000mAh batteries each weighing 1.8 pounds. On a craft that weighs 14 pounds, that's not a huge percentage.Tthey give 30-45 mins of flight time. Who said it needed 5 hours of flight time? 5 hours of processing time yes. Once you have your sample data, you don't need to stay airborne.
500 separate components are all software on a pico-itx computer. OK there will need to be receiver electronics for the radio, but all not a huge drain on battery.
And that tiny fixed pitch prop is a 17"x10" on Eflite Power 90 Brushless motor. Looking at the specs for the motor, this combination of prop and motor is sufficient for the weight of this model.
Uses a 900MHz radio system with a line-of-sight range of over 30,000 feet with a dipole antenna. With a high-gain antenna this range is more than doubled. USes a bespoke groundstation that provides telemetry. I wouldn't be suprised if you used an on-board camera to fly with once airborne - much like military drones.
Quite a difference to the conventional RC gear. Things have advanced quite a bit.
Oh, and fiction, check out the video on their website.
So you assemble all the PCBs yourself??!!
that still won't stop your friends tagging you manually in the photos. You can always go and de-tag yourself.
iTunes - why?
iTunes is one major bugbear of mine. Why should I need to have a separate app to put music onto my device. It is, at the end of the day, a USB storage device. I should be able to just drag and drop the music into a folder on the device from an OS built-in file manager. I don't want to have an app to manage my music, I'm more than capable of doing it myself. Plus 99% of my work is in an OS other than winblows or OSX, for which there is no iTunes available.
Doesn't just work out of the box.
Well, maybe it does if you run Windows or OSX. Seems they haven't heard of Linux.
OK, so it's looking a bit battered - stone chips out of the ally case where I've dropped it, and a noticeable bend where I walked into a bollard when it was in my thigh pocket, but the screen is still pristine and the slider works flawlessly.
Just wish their update policy was a bit more speedy.
The V+ box I have at the moment has 3 tuners. Can record two channels and watch a third. OK, has a 160GB hard drive (for up to 80 hrs recording).
So the only benefits are more storage and the ability to go back for a "best TV of the week" (which is highly unlikely to be anything I'm interested in!)
So, I'd probly only be interested when a 5 tuner system is out so I can record those 4 programs that overlap, while watching the 5th. An added feature could be the dynamic program guide that can compensate for sports events running over, or changes in the schedule. Save me having to fast-forward through 3 hours of snooker to find out the program wasn't on in the first place!!
Title? What title?
We use MSO at work, but I have a WinPenPack release of the latest LibreOffice beta. Been many a time I've used LO as opposed to MSO due to Microsloth's limitations. (spreadsheet row/column number limitations, row height limitation, and text file import).
Use open office at home with no issues whatsoever. the only reason I'm using the LO version occasionally at work is the OO version has that damn ugly Oracle logo on it's splash screen and it complaining about a missing file.
Libre Office does have some patches implemented in it that OO doesn't (don't recall the extra features/improvements) so it's probably going to have improvements happen faster than in OO.

The Polyus is on the same launch system (Energia) that sent Buran on it's one and only orbital excursion. An unmanned launch that ended with a fully automated landing at the Baikonur cosmodrome (something the shuttle couldn't do - needs someone to lower the undercarriage!).
My Milestone has no problem with the protected apps. Both the apps mentioned in the original post are there and ready to be purchased from the Marketplace.
