Well at first glance, it may not be a big deal, but this changes this course of history for skateboarding. New possibilities were created when urethane wheels emerged; a faster smoother ride was now available. A noisy, bumpy ride turned into a smooth and quiet ride. These wheels allow for immense grip to the concrete and the invention of these wheels was going to bring skateboarding back into the limelight. Later in the s innovations such as aluminum decks were invented.
However, now mainstream media would start to cover skateboarding. The danger of skateboarding still tainted the sport, and many public skateparks were shut down due to high insurance rates. Many new tricks were perfected and invented on skateboards during the s, which made many interested in improving them. In one of the biggest skateboard companies ever was founded, Trasher Magazine which to this day remains as a huge skating powerhouse.
More and more skate companies were founded. This frames skating as an adrenaline hunting sport and skyrockets the popularity of the sport. The s bring skateboarding as a type of transport. As more and more skateparks are created more and more people bring to pick up the hobby. Today skating is thriving, and the professional scene and casual scene are both on an up. Well, the heart of skateboarding is in Californa, and this is where the origins of skateboarding can be linked to.
Also, Hawaii had a significant impact on the earlier stages on skateboarding. Rodney Mullen is known as the godfather of street skating, and for a good reason. Mullen is by far the best technical street skater to ever walk the earth.
Mullen first invented the Ollie, which is known as the first skateboard trick. It is debatable why people skateboarding was invented, but the consensus is that skateboarding was first created because many surfboarders wanted to ride the waves on the street.
To see when skateboarding was invented, we have to go back to the s when surfboarders invented it. The first skateboard was just a wood plank and was invented s, so this is when skateboarding started at its roots.
It is Nast who gave Santa his bright red suit trimmed with white fur, North Pole workshop, elves and his wife, Mrs. Nicholas-inspired gift-giver to make an appearance at Christmastime. There are similar figures and Christmas traditions around the world. Christkind or Kris Kringle was believed to deliver presents to well-behaved Swiss and German children. Nicholas on his holiday missions. In Scandinavia, a jolly elf named Jultomten was thought to deliver gifts in a sleigh drawn by goats.
In Italy, there is a story of a woman called La Befana, a kindly witch who rides a broomstick down the chimneys of Italian homes to deliver toys into the stockings of lucky children. In the United States, Santa Claus is often depicted as flying from his home to home on Christmas Eve to deliver toys to children.
Stockings can be filled with candy canes and other treats or small toys. Santa Claus and his wife, Mrs. Children often leave cookies and milk for Santa and carrots for his reindeer on Christmas Eve.
He sees you when you're sleeping He knows when you're awake He knows if you've been bad or good So be good for goodness sake! The red-nosed wonder was the creation of Robert L. May, a copywriter at the Montgomery Ward department store. In , May wrote a Christmas-themed story-poem to help bring holiday traffic into his store.
Montgomery Ward sold almost two and a half million copies of the story in When it was reissued in , the book sold over three and half million copies.
It was recorded by Gene Autry and sold over two million copies. Since then, the story has been translated into 25 languages and been made into a television movie, narrated by Burl Ives, which has charmed audiences every year since But if you see something that doesn't look right, click here to contact us!
Subscribe for fascinating stories connecting the past to the present. Christmas is celebrated on December 25 and is both a sacred religious holiday and a worldwide cultural and commercial phenomenon. For two millennia, people around the world have been observing it with traditions and practices that are both religious and secular in nature.
Christmas traditions around the world are diverse, but share key traits that often involve themes of light, evergreens and hope. Probably the most celebrated holiday in the world, our modern Christmas is a product of hundreds of years of both secular and religious traditions SSDs of this type are usually fitted with DRAM modules of the same type used in regular PCs and servers, which can be swapped out and replaced by larger modules.
A remote, indirect memory-access disk RIndMA Disk uses a secondary computer with a fast network or direct Infiniband connection to act like a RAM-based SSD, but the new, faster, flash-memory based, SSDs already available in are making this option not as cost effective. While the price of DRAM continues to fall, the price of flash memory falls even faster. Some drives use a hybrid of spinning disks and flash memory. A directory of block placement and wear leveling data is also kept in the cache while the drive is operating.
Data is not permanently stored in the cache. Another component in higher performing SSDs is a capacitor or some form of battery. These are necessary to maintain data integrity such that the data in the cache can be flushed to the drive when power is dropped; some may even hold power long enough to maintain data in the cache until power is resumed.
In the case of MLC flash memory, a problem called lower page corruption can occur when MLC flash memory loses power while programming an upper page.
The result is that data written previously and presumed safe can be corrupted if the memory is not supported by a super capacitor in the event of a sudden power loss. This problem does not exist with SLC flash memory. The host interface is not specifically a component of the SSD, but it is a key part of the drive. The interface is usually incorporated into the controller discussed above. The interface is generally one of the interfaces found in HDDs.
They include:. The size and shape of any device is largely driven by the size and shape of the components used to make that device. Traditional HDDs and optical drives are designed around the rotating platter or optical disc along with the spindle motor inside.
If an SSD is made up of various interconnected integrated circuits ICs and an interface connector, then its shape could be virtually anything imaginable because it is no longer limited to the shape of rotating media drives. Some solid state storage solutions come in a larger chassis that may even be a rack-mount form factor with numerous SSDs inside.
They would all connect to a common bus inside the chassis and connect outside the box with a single connector. For general computer use, the 2. For desktop computers with 3.
Other types of form factors are more common in enterprise applications. An SSD can also be completely integrated in the other circuitry of the device, as in the Apple MacBook Air starting with the fall model. The benefit of using a current HDD form factor would be to take advantage of the extensive infrastructure already in place to mount and connect the drives to the host system.
These traditional form factors are known by the size of the rotating media, e. For applications where space is at premium, like ultrabooks or tablets, a few compact form factors were standardized for flash-based SSDs.
It remains electrically compatible with the PCI Express Mini Card interface specification, while requiring an additional connection to the SATA host controller through the same connector.
