SSD or Solid State Drive is the alternative for the more traditional hard drives found on laptops and pc's, and there are a number of differences between the two storage devices.
The traditional hard drives found on pc's and laptops have some moving parts which include the spinning disc (where the magnetic data is stored) and an arm that moves around inside (which actually reads the data from the disc)
A SSD has no moving parts though, but it does have a limited amount of times that data can be writen to the device. Because there are no moving parts, it is also silent and accessing the data is much faster than a conventional hard disc. One of the biggest advantages also, is the fact that a SSD normally uses less energy, and is much more robust, being more resistant to external impact such as bumping or dropping which would normally damage traditional hard drives.
Probably one of the biggest manufacturers of SSD's - SanDisk, released their SanDisk Netbook SDHC Removable Flash Memory Card in June 2009. One drawback for SSD's are that until now, they have been fairly expensive compared to normal hard drives.
SDD's will probably become the norm eventually, replacing the normal hard drives we have today, but for that to happen the technology needs to become cheaper. This will most likely happen over time, as new technology continues to improve on, and even replace more traditional technologies.
While this technology is already in use in data-centers, it hasn't beached into mainstream computing yet. As current electricity-based solutions begin seeing their limit, it was only a matter of time.
In the coming year Intel plans to release this technology for use in consumer devices and mainstream computing, for the first time giving people the taste of transfer speeds up to 10Gbps. Over the decade Intel hopes to bring this up to 100Gbps.
Since this as optical technology, multiplexing multiple connections over a single cable will be much simpler, and thus a single cable cold be used to connect your computer to multiple "peripherals, workstations, displays, disk drives, docking stations, and more."
Light Peak is designed to be cheap, and in fact claims to be smaller and cheaper than current telecom modules. The Light Peak optical modules are up to 120 times smaller and up to 30 times cheaper than current telecom modules! The optical fibres used in it are in fact nearly as thin as human hair, and use LASER chips called VCSEL (Vertical Cavity, Surface Emmiting LASER) which are a mere 250 microns by 250 microns.

Now Linus Torvalds, the one who started it all, has himself claimed that Linux, has begun to acquire some unnecessary fat. During LinuxCon on Monday, he claimed, "We are definitely not the streamlined, hyper-efficient kernel I envisioned when I started writing Linux."
Most Linux fans would love to claim that it is evolving faster than Windows, yet that also means that it is accumulating features and bloat as much faster!
Even so the thing to note here is that while one wouldn't dream of running Windows Vista on a 5 year old computer, one can get nearly any recent distribution of Linux running on even a 10 year old computer with a little bit of optimization. This isn't just because Linux is more optimized, but also because Linux still supports those old chipsets.
Any popular software is popular because it caters to the needs of a wide range of people, and as Linux gets more popular, it risks the chance of bloat in the forms of features and support for hardware which only a few really need. Linux is created to fit in everywhere from a PS3 to a research laboratory!
An interesting statistic: on an average, 10923 lines of code are added to the Linux kernel every day and 5547 lines are deleted every day. This still means that the Linux kernel is growing at a rate of 5376 lines of code a day.
While many Linux users enjoy the freedom of choice that the OS supplies by allowing the desktop environment, the command line, the file manager, and nearly everything, to be replaced, few touch the Kernel itself, and as such it is that which needs to be optimized.
Linux is surely getting bloated, and chances are your stock kernel is filled with support for hardware which you have little chance of encountering, and features you are unlikely to use. However, the fact that it is still possible to use Linux in embedded devices (Moblin, Android, Maemo, Linux on the Amazon Kindle, etc.) is thanks to the fact that the Linux Kernel is open source and highly configurable and adaptable.
Over time software are bound to accumulate features which will have little use to many of the people who use it and people will have to realize Linux is no exception.

- “The announcement of LG’s first Android-powered smartphones comes only a week after the world’s third largest mobile phone company announced that it would be introducing three new Windows Mobile smartphones in the next few weeks. These developments underscore LG’s commitment to offering greater consumer choice in the expanding smartphone category."
- “In addition to the Android model, LG announced in early September that it will be introducing a minimum of 13 new smartphones over the next 16 months that utilise Microsoft’s Windows Mobile. The newest release, version 6.5, was announced just last week.”
If you're a fan of Netbooks, and also a fan of Nokia, you'll soon be able to indulge your preference. On 2 September 2009, Nokia plans to release availablity and pricing details for their new netbook called the"Booklet 3G"
Yes, Nokia is bringing out its own kind of Netbook, and even though it may look like a regular netbook, it will carry the classy, smooth design we're used to see from Nokia.
The Booklet 3G will be Windows based and powered by the popular and efficient Intel Atom processor with a whopping 12 hour battery life. This means people will be able to leave their power cables behind a little more often, without losing connectivity.
Weighing only 1.25 kilograms, this new lightweight plans to pack a significant punch with its highly portable alluminum casing. It's little more than 2 centimetres thick.
Connectivity options include 3G/HSDPA as well as Wi-fi, offering users high speed access to the internet.
The device features a HDMI port enabling HD video out, a built-in camera for video calling, bluetooth and SD card reader. Featuring a 10-inch glass HD ready display and a built-in A-GPS (which works with the Ovi Maps gadget), pinpointing your exact position takes only seconds.
We cannot really be surprised by this move, considering that Nokia is one of the world's leading providers of connectivity. Considering that Nokia is probably one of the most well known names in the world today, consumers should be able to look forward to be able to add to their list of gadgets the new Booklet 3G.
Nokia seems to be upping their game every time a new product is released, and we expect pretty much the same this time. Of course consumer expectations will likely be high with this new addition to their product line, but if Nokia continues to deliver the high quality we've grown accustomed to over the years, I'm sure it will be a hit with users.
The last 10 years or so has seen a significant increase in watersports, with new technology on boats and other forms of entertainment such as the jet-ski becoming very popular.
We've even seen an off-road quad bike transform into a jet-ski at the push of a button. However, the JETLEV-FLYER is truly unique and interesting, some may even say slightly off the wall, but very interesting none the less.
You may have seen those modern day jet-packs on display somewhere - you know, the one where the pilot straps a jetpack to his back, and literally takes off like a rocket. The JetLev-Flyer however is slightly different in the sense that instead of using a gas propulsion system, it uses water. The system was designed for watersports afterall.
After a period of about 9 years of development, testing and refinement, the manufacturers are now confident that they have a product that is literally...taking-off.
So how does it work?
The JetLev-Flyer uses a powerful 4-stroke engine poducing (155 - 215 HP), and water nozzle reaction force that results in a stable and controlled flight experience for the user. The controls are light, simple and intuitive, able to accomodate pilots of between 1,50 and 2,00 meter in height, and 40 - 120 kilogram in weight.
The system uses a digital fly-by-wire system to control the throttle.
According to the company's website, a standard JETLEV-FLYER can reach a height of 10 meter, able to cruise for one to two hours, and has a top speed of 65km/h. Future designs may be developed to reach higher altitudes and faster top speeds, with an exended range of up to 300 kilometres. It is reportedly very easy to learn and operate.
Now you're probably wondering how exactly a pilot can stay in the air for that long. The solution is rather simple. Instead of storing its propellant (water) inside or on the JETLEV-FLYER, the actual engine remains on another vessel that trails behind the pilot on the water surface. The vessel and JetLev-Flyer is connected by a rather large waterhose. Water is sucked in from the water surface, and then pumped up to the nozzles on the pilot's back through the hose connecting the two. Using this method, the pilot does not carry any excessive weight such as an engine or fuel.

Well, this week we saw BMW release details of their latest sports concept car, but it's more than a sportscar.
BMW Vision EfficientDynamics is a combination of the potential of BMW ActiveHybrid technology, and the power of BMW EfficientDynamics.
Technology on BMW Vision EfficientDynamics concept car consists of a full-hybrid concept, and is powered by a three-cylinder turbodiesel and two electric motors
The combination of these technologies provides overall system output of 262 kW/356 hp, with maximum torque at 800 Newton-metres/590 lb-ft. The car is an all-wheel drive consisting of an electric motor on both rear and front axles.
Projected performance is anticipated to be in the region of zero to 100km/h in 4.8 seconds, with a top speed of 250 km/h (155 mph) - this is electronically limited. Fuel consumption in the EU test cycle measured at 3.76 litres/100km, with CO2 emissions 99 grams/kilometre.
Electric power is generated without compromising any fuel consumption efficiency, using a particularly efficient concept of Brake Energy Regeneration. The energy is stored in 98 lithium polymer cells, with a range of about 50 km using the electric mode alone.
Article continues below the images:
The aerodynamics have been developed with input from Formula 1, and the result is a drag coefficient that has been optimised to just 0.22.
The body has been designed with consistent lightweight technology as well as aerodynamic technology, with these qualities ensuring optimised sporting performance, as well as excellent efficiency.
On top of all this, the car features a 4 seater capacity which makes it not only a sports car but also well equipped for all round use.
Possibly, the cherry on top for some buyers will be the implementation of Gullwing doors, which open upwards. Even the doors have been designed to make entering and exiting the vehicle easy, making use of weight-optimised door kinematics.
And of course, moving onto the interior, the cabin has been designed using the very latest in modern technology. Last but not least, the roof and door inserts (made of polycarbonate glass) automatically become darker in light conditions, easing eye strain on both driver and occupents.
Having said all this, the car looks incredibly impressive, and BMW has once again shown why they are among the leaders of innovation, style, efficiency, class and performance. What more can we say?...It's a BMW.
Turning Roads Into Solar 'Power Stations' - A Brilliant, Fresh Approach From Solar Roads Founder Scott Brusaw
Every once in a while, a really brilliant idea comes along, and we find ourselves wondering: Why didn't I think of that?
Well, this has got to be one of those brilliant ideas. Energy, especially solar energy, is a very hot topic these days. And with good reason. As the world's energy demands grow, the resources needed to supply this power seems to be getting less and less.
So, we have to think 'out of the box' to come up with a sustainable solution.
And that is exactly what Scott Brusaw from Solar Roadways, in Idaho USA, has done. What's more is that U.S. Department of Transportation is so impressed with his proposal that they have granted Solar Roadways USD$100,000 to further develop his prototype that turns roads into giant solar panels. The idea and the research behind it also makes a lot of sense in terms of cost, and environmental impact.
Firstly, Mr Brusaw believes that solar panel roads may last up to three times longer than current petroleum-based asphalt surfaces which have an average lifespan of about 7 years at a cost of USD$16 per square foot. Mr Brusaw hopes to produce solar panels with a lifespan of 21 years for USD$48 per square foot, which would not only save the inconvenience of road maintenance, but would also cost the same as a conventional asphalt road. Allright, so if it costs the same, then why implement solar roads instead of asphalt? Well, the answer is simple.
Although it costs the same, the solar power generated from the solar roads could potenially be more than what is needed for every home on the entire US power grid. In fact, if you were able to convert all the existing roads, parking lots and driveways in the US to solar panel roads, there would be more than three times more electrical power available than what all the homes in the entire US requires.
These calculations are not based on a more efficient type of solar panel, they are based on the average efficiency of a solar panel (which is only 15%). In effect, for this to work you do not even need to build more efficient solar panels. The efficiency on existing models produced will be enough.
Now, in addition to homes being powered just from this 'road grid', these roads can also be fitted with LED's that would further enhance driver experience by lighting up the roads much like the runway lighting seen at airports. The challenge now, is just to design the glass for the solar panels to have the same traction and load bearing qualities as current asphalt roads. But, Mr Brusaw says he has already spoken to scientists at Penn State University’s Materials Research Institute, and they have assured him they would have no problem in producing the type of glass with these requirements.
To put all of this into perspective, if they would replace one mile of a multi-lane highway with solar panels for instance, that would be enough to generate enough electricity to supply 500 homes completely, without having to tap into the main power grid. And all this can be done with an average of only 4 hours of sunlight per day.
If this system is implemented, Mr Brusaw says solar roads would be able to generate enough electricity to replace all centralized power stations (coal and nuclear powered plants included)
You start with an ambition, a raging desire to do something big and something that adds meaning to your and then, after a while, it all fizzles out. You stop doing things that should have put you on the path to success. Instead, you start doing things that lead you to nowhere, because these things — those that lead you to nowhere — are easy to do.
When it comes to business, making money, earning fame and respect or feeling loved – there is consistent effort involved. There is a lot of work that goes in and most of it is done without a thought.
Take it easy, they say. How wrong could they get?
Easy is the word that plagues many of us and we are blissfully unaware of this. We don’t want to work hard but yet we creave for things that are made possible only to those who work hard for it. We know it all, we don’t do a damned thing about it.
Money is confusing for a lot of people; they have no idea about what they want to do with it when they have it and when they don’t have it, they despair. Everything else in between is even more vague.
Here’s the principle: There is all the money in the world if you want it; it’s just that you have to sacrifice your sweat for it. Apart from the really successful entrepreneurs you and I are aware of, there are many more people I know who are a living testimony to that fact. They put in long hours and they follow “delayed gratification”. They sacrifice fun, family and relaxation just so that they can hit the nail home.
Money comes in where sweat goes. Without sweat equity, there can be no enterprise. No sweat, nothing is ever sweet.
You got to start by working hard and then find ways to accomplish your tasks in a smart manner. By doing it well and optimizing your efforts, you can establish a system which will form an enterprise. This is what entrepreneurship is all about, isn’t it?
No matter what you are currently doing in life, please do sweat it out. Without that, you will walk out of that door with nothing in your hand but shame that comes from incompetence.
