  1. My first job when I was 15 was working in an electronics store where I sold ink refills and third party cartridges. My second job was working for a company that repaired printers and computers. I think people should be able to refill their cartridges but understand the risks and it should void their warranty. On opening a printer I could immediately tell if they had used third party ink in them. Among other things was the big build up of sediment they didn't get with genuine inks. So go ahead and use third party inks, I do today, but don't cry when your printer breaks.

  2. Entirely Possible on Sonic Skydive's Real Aim Is To Help Astronauts Survive · · Score: 1

    It is completely impractical to compare this with a space shuttle re-entering. The mass difference alone makes it a completely different problem. Also a space shuttle burns tons and tons of rocket fuel in exchange for altitude and velocity. This requires a lot of energy - energy that when it needs to return to Earth the space shuttle needs to get rid off, it does this by converting it to heat. For this project, a balloon is being used to provide the lift. This gives it the potential energy of height, but not the velocity needed to retain orbit. Once you take away the lift- you return to Earth. Coupled with the massive weight difference means there is no where near as much energy that must be converted into heat. A skydiver reaches terminal velocity as a result of their mass and surface area presented to the relative wind. Terminal velocity also depends on air density - altitude and temperature. So a skydiver can go faster by increasing their mass, reducing the cross-sectional area presented to the relative wind or jump from higher altitudes (or on warmer days). In fact even from an altitude of 13,000ft a skydiver will reach terminal velocity after 1000ft and then gradually slow down as the air density increases. Felix will be seeing this on a much grander scale - less air, higher terminal velocity but less friction. Also the speed of sound is slower at higher altitudes because the air is thinner. Some sources actually credit Joseph Kittinger with breaking the speed of sound at his altitude. There are various problems that must be solved for this to succeed, but I think its entirely possible and I am looking forward to seeing him pull it off.

  3. This isn't gliding on Jetman Attempts Intercontinental Flight · · Score: 1

    Flying 23km's after exiting from 6,500ft is far from gliding. A skydiver typically deploys their parachute between 3000ft and 4000ft and often higher in technical jumps such as this. This means he must maintain an almost flat glide angle, thus requiring thrust making it a powered flight, not a glider. Wingsuiters have flown these sort of distance but they exited from around 23,500ft and utilised tail winds.

  4. It is possible! on Qantas Blames Wireless For Aircraft Incidents · · Score: 1

    I have personally seen interference between aircraft controls and a wireless mouse! Whenever a colleague flew his remote control helicopter it would prevent another persons wireless mouse from working. So it seems perfectly plausible that a wireless mouse could affect a jet!

  5. Not good for your printers on How Aftermarket Inkjet Ink Holds Up After a Year · · Score: 1

    My first job was working for an electronics retailer. We were encouraged to sell 3rd party ink because it was cheaper but had a higher profit margin. My next job was working for a small IT company that repaired canon printers. After working there for a while I could tell if a printer had been using refill inks by the look of the ink, the print quality, the condition of the print head but most of all the condition of the purge unit. The purge unit in printers that had been using refills were always clogged with sediment and had to be replaced. After seeing the results of what happened to printers that had been refilled I will never touch refill inks again.

  6. Jet Powered Man on New Personal Mono-Wing · · Score: 1

    Reportedly in later stages of development they are looking at attaching engines to provide thrust to the wing. I have seen footage of a guy using a more convential wingsuit with small jet engines strapped to his feet. It was impressive to say the least, if I recall he was able to maintain level flight for sometime, but would stall his body if he tried to climb.

    HAHO has the added advantage of being able to take a "Mission Specialist" in as a tandem passenger.

    The Amazon rainforest, sometimes referred to as the Lungs of the Earth, uses more oxygen than it produces. Rotting trees and plant products requires a large amount of oxygen.

  11. Heater on NVIDIA and Dell Display Quad-SLI System · · Score: 1

    There have often been times where I have thought "I really need a computer with 4 GPU's", but the added benefit is I won't need central heating in winter!

  12. Re:Epic could learn from Duke on UT 2007 Might Make The PS3 Launch · · Score: 1

    This is sounding more and more like Duke Nukem Forever. Its release date is also "When its done". I believe they are changing the name to Duke Nukem Whenever.

  13. Powerbook 190 on Apple Laptop Reliability Survey · · Score: 1

    I was in a Laptop class in school many years ago. We all had student owned PowerBook 190's. At any given time a quarter of the laptops would be in the ship being repaired.

  14. Bird-Man Suits on Jet Powered Human Flight · · Score: 3, Informative

    The Bird-man suits use inlet vents to create aerofoils similar to a ram-air parachute. The lift created is strong enough so that a skilled wing suit pilot can momentarily rise above a tail gate aircraft on exit. The jet engines provided enough thrust to keep the pilot level, but not enough to gain altitude. I have no doubt that this will be the next goal they will try to achieve. There is also a wing suit pilot who has said he thinks it is possible to "land" a wingsuit without the use of a parachute.

    What happens to the bounty if the goals are never achieved? Does it just keep growing for ever, gaining interest or will it be put to good use if the goals are not reached be a certain deadline?

  18. Freefall on Indian Tycoon Sets Balloon Flight Record · · Score: 1

    Personally I preferred Kittinger's return to earth. He jumped over the side and performed the world's highest skydive. From 69000 to a deploy height of around 3000ft you'd get over 5 minutes of freefall. :) That would be worth setting a new height record to do!

  22. Open Mind on New Discovery Disproves Quantum Theory? · · Score: 1

    It seems frustrating to me that so many scientists can dismiss these claims so easily. "It doesn't comply with our laws of quantum physics" SO! Our laws of quantum physics should really be described as works in progress. 100 years ago or so we were told the sun was made of coal...err but it only has enough mass to burn for 1 million years, yet the earth is at least several hunder millions of years old...hmmm... lets just sweep that under the carpet for now. Then came nuclear fusion, suddenly it all made sense. The laws of quantum physics are not set in concrete and I have now doubt they will be refined and some point, maybe the time is now, or maybe not.

  23. Been there, done that on PC Gaming On The Comeback Trail · · Score: 1

    I use to work in the computer department of a large retailer. We had a couple of PCs setup with games that the public could try. We kept it up to date - often changing the game that was on there, would put a good joystick on for flight sims and a steering wheel on for racers.
