Picture of The Day- What’s Up With This YouTube

I pay extra for my “High Performance Internet” from Comcast which boasts a 25 MBPS download speed. I was able to get that speed only up to about two weeks after the upgrade. Now I am only averaging about 15 MBPS. That’s one problem I will have to address Comcast about, but the picture below depicts another problem that I am totally confused about.  The problem is I can be trying to watch a YouTube video and it freezes. Now I watch most videos full screen in 1080i if possible,  but the problem persists at even lower quality settings. Now a lot of people suffer from this problem that have slower connection speeds, but should I really be having the problem with the current speed of my ISP verified from SpeedTest.net? I don’t think so, but as you can see from the picture below is that according to the gray part of the bar on the bottom of the video, it can be buffered and still not playing on my Quad-core. What’s up with this? Is it a YouTube problem or what. It seems that Google’s servers on YouTube have been getting slower instead of faster over the year. That’s another story, but what about the “buffering”. Are they trying to pull the wool over our eyes or is this a flash problem or what? Any ideas?

Back almost 30 years ago, I was into OS9 (no not Apples OS9) which is a multiuser, multiprocessing, operating system based off of Unix from AT&T. It was a very powerful OS for 8-bit computers initially using the Motorola 6809 processor. If you were even into computers back in the early 80’s when I first got introduced to computing and programming, you were probably into CP/M or worse yet MS-DOS. I read about those but was more intrigued with the power of the OS9 Level 1 and 2 operating systems. Having friends and working in retail selling computers and electronic devices, we were always arguing about which system was better. In my research, I was finding out that the Radio Shack Color Computer was not much compared to the other 8 bit computers popular at the time like the Commodore 64. However, when you booted up with an old 5-1/4” floppy that only held 160K, that had the OS9 Operating System on it, you were in another league. The Commodore 64 and any MS-DOS machine and later the earlier versions of Windows up to say 3.0, were no comparison as features (power) goes. OS9 RULED !!!

OS9 soon was ported to the more powerful 16 and 32 bit computers using the 68000 CPU and has since dominated the Industrial embedded chips used in manufacturing and other complex systems. It is very reliable and is still a major operating system.

However, in the early 90’s came along Linus Torvalds – The Creator Of Linux. In 1991 he made his soon to be know Linux Operating System public and the result is an operating system that in my opinion has the best of Unix and OS9 combined making it the worlds BEST Operating System. Fighting off the popularity of Microsoft’s Windows Operating System, Linux has established itself behind the backs of people unfamiliar with Linux. To most, they aren’t even aware of what Linux is, let alone what it is used for. But Linux is now used in many devices that everyone uses everyday. They are just now becoming more aware of it thanks to great articles published by Mashable.com and others. Google now with the worlds most popular phone OS, Android, is bringing more attention to Linux as Linux today is celebrating it 20th Birthday.

Happy 20th Birthday Linux !

Here is a great article by Mashable.com

The Linux operating system is not just for nerds. Even though you may not realize it, chances are you probably have a version of Linux running right under your nose. It’s found its way into a multitude of devices, both large and small.

Today, Sept. 17, 2011, is the 20th anniversary of the date when the first Linux kernel (version 0.01) was released and uploaded to an FTP server by Linus Torvalds in Helsinki. Although Torvalds had been working on the code since April, 1991 (recognized by some as the birthday of Linux), it wasn’t until September of that year that he released the first Linux kernel to the world. That early iteration consisted of a mere 10,239 lines of code.

Fast-forward to the present day, where the Linux kernel 2.6.35 contains more than 13.5 million lines of code, and controls gadgets, devices and instruments you might never have expected. Take a look at our gallery below and be surprised by the ubiquity of this useful, versatile and compact operating system on its 20th birthday:

1. TiVo

Underneath the digital video recorder TiVo’s user-friendly and popular interface is a modified version of Linux. We have a hunch that those Linux underpinnings are responsible for TiVo’s snappy response and smooth video playback.


2. Android

The Android operating system is showing up in multitudes of handheld devices. It was created by the Open Handset Alliance, headed up by Google. Lots of smartphone providers place their own brand of user interface enhancements on top of Android, and there’s a lot of tricky programming called middleware in between, but underneath? Good old Linux.


3. AT&T MiFi

This pocket-sized device gives users a mobile access point that makes it so multiple people can use a single 3G connection. That gives any Wi-Fi device the ability to go online practically anywhere. What’s in it for you? Imagine never having to pay a $12.95 Wi-Fi charge in a hotel again, thanks to Linux.


4. Large Hadron Collider

When it’s time to answer big questions, physicists are turning to Linux to run the Large Hadron Collider, the world’s largest and highest-energy particle accelerator. Just what questions are they trying to answer with this $9 billion scientific instrument? They’re trying to understand some of the deepest and most fundamental laws of physics, such as the structure of space and time.


5. Refrigerator (Electrolux Infinity I-Kitchen)

Why would you need Linux in your refrigerator? How about running a touchscreen on the front, storing your contacts and calendars, recipes and reminders, and letting you keep your family organized with electronic Post-it notes? And, some refrigerators are smart enough to remind you that it’s time to buy more milk.


6. Sony Bravia HDTV

We tested the latest Sony Bravia connected TV, which brings you your favorite video-on-demand service from Netflix or Amazon and a lot more. That’s thanks (in part) to its Linux underpinnings. Of course, it can show you the latest 3-D video, and the one we tested was even smart enough to turn itself off if there was no one sitting in the room.


7. Chumby

This little supersmart alarm clock runs more than 1,000 apps, and it’s all made possible by Linux under the hood. Don’t let its diminutive size fool you — this gadget can display video, call up your favorite Pandora Radio channels and remind you of appointments. Best of all, it’s fun.


8. GPS (Tom Tom)

Bet you didn’t know that GPS unit on your car’s dashboard was running Linux. Humming away inside many Garmin, Tom Tom (and other) GPS navigators are versions of Linux. Now if the accuracy of the maps could measure up to that sharp Linux code running inside, we wouldn’t have to recalculate so often.


9. Kindle

The electronics reader that made e-reading famous is the Amazon Kindle, and displaying its E-Ink screen with enough speed to make it a pleasure to use is — you guess it — starts with an "L."


10. Self-Driving Car

Self-driving cars, otherwise known as autonomous vehicles, are not perfect yet, but they’re getting there. Many of them are running Linux, and researchers are using the operating system to find their way toward someday eliminating the need for traffic signals, driver’s licenses, and maybe even rules of the road.

Google To Acquire Motorola Mobility

To Protect And Defend ANDROID Dominance

     

Since its launch in November 2007, Android has not only dramatically increased consumer choice but also improved the entire mobile experience for users. Today, more than 150 million Android devices have been activated worldwide—with over 550,000 devices now lit up every day—through a network of about 39 manufacturers and 231 carriers in 123 countries. Given Android’s phenomenal success, we are always looking for new ways to supercharge the Android ecosystem. That is why I am so excited today to announce that we have agreed toacquire Motorola.
Motorola has a history of over 80 years of innovation in communications technology and products, and in the development of intellectual property, which have helped drive the remarkable revolution in mobile computing we are all enjoying today. Its many industry milestones include the introduction of the world’s first portable cell phone nearly 30 years ago, and the StarTAC—the smallest and lightest phone on earth at time of launch. In 2007, Motorola was a founding member of the Open Handset Alliance that worked to make Android the first truly open and comprehensive platform for mobile devices. I have loved my Motorola phones from the StarTAC era up to the current DROIDs.
In 2008, Motorola bet big on Android as the sole operating system across all of its smartphone devices. It was a smart bet and we’re thrilled at the success they’ve achieved so far. We believe that their mobile business is on an upward trajectory and poised for explosive growth.
Motorola is also a market leader in the home devices and video solutions business. With the transition to Internet Protocol, we are excited to work together with Motorola and the industry to support our partners and cooperate with them to accelerate innovation in this space.
Motorola’s total commitment to Android in mobile devices is one of many reasons that there is a natural fit between our two companies. Together, we will create amazing user experiences that supercharge the entire Android ecosystem for the benefit of consumers, partners and developers everywhere.
This acquisition will not change our commitment to run Android as an open platform. Motorola will remain a licensee of Android and Android will remain open. We will run Motorola as a separate business. Many hardware partners have contributed to Android’s success and we look forward to continuing to work with all of them to deliver outstanding user experiences.
We recently explained how companies including Microsoft and Apple are banding together in anti-competitive patent attacks on Android. The U.S. Department of Justice had to intervene in the results of one recent patent auction to “protect competition and innovation in the open source software community” and it is currently looking into the results of the Nortel auction. Our acquisition of Motorola will increase competition by strengthening Google’s patent portfolio, which will enable us to better protect Android from anti-competitive threats from Microsoft, Apple and other companies.
The combination of Google and Motorola will not only supercharge Android, but will also enhance competition and offer consumers accelerating innovation, greater choice, and wonderful user experiences. I am confident that these great experiences will create huge value for shareholders.
I look forward to welcoming Motorolans to our family of Googlers.

Rubik’s cube ‘riddle’ can be solved ‘in 20 moves’, scientists using Google PC discover

 

The Rubik’s cube conundrum can always be solved in 20 moves or less, an international team of scientists and Google engineers have discovered.

25 Second Speed Cubing

 The “riddle” of the minimum number of moves required to solve any configuration of the popular toy has stumped its users, and mathematicians, for almost three decades.

But now the team of researchers, based in Palo Alto, California who used Google computers, have discovered that any combination can be solved in no more than 20 moves.

Experts say this figure is known as "God’s number", which is based on an assumption that even an “all knowing entity” could not solve the puzzle faster.

The results suggest there are more than 100,000 starting positions that can be solved in exactly 20 moves although the majority of solutions take between 15 and 19 moves to piece together.

The researchers combined the search engine giant’s computing power with mathematical expertise to check more than 43 quintillion (43,252,003,274,489,856,000 to be exact) possible jumbled positions the cube can take.

Prof Morley Davidson, a mathematician from Kent State University, Ohio, a member of the team, told the BBC: "We now know for certain that the magic number is 20.

"It’s come full circle for me. Rubik’s cube was an icon of the 80s when I was growing up and was the reason I went into mathematics.

"It’s the universal popularity of the puzzle – it’s probably the most popular puzzle in human history."

The initial results have been published online and Prof Davidson said they would now be submitted to peer-reviewed journals.

Tomas Rokicki, a programmer who has spent the past 15 years searching for a solution, said the team’s computer algorithm could try out 1 billion cubes per second. Previous computer methods could only solve around 4,000 possible cubes a second.

“The primary breakthrough was figuring out a way to solve so many positions, all at once, at such a fast rate,” he told the New Scientist magazine.

To simplify the problem, the team of researchers used the mathematics technique called group theory.

According to the New Scientist, they first they divided the set of all possible starting configurations into 2.2 billion sets – each containing 19.5 billion configurations – according to how these configurations respond to a group of 10 possible moves.

This grouping then allowed the team to reduce the number of sets to just 56 million, by exploiting various symmetries of a cube.

The team’s algorithm rapidly matched moves to the correct starting point, allowing them to solve each set of 19.5 billion in less than 20 seconds.

At this speed completing the entire task would take around 35 years for an ordinary home computer.

In 2007, The Daily Telegraph reported that any configuration of a Rubik’s cube could be solved in 26 moves, or less.

Others have since found it to be less, although Prof Davidson said this was “pure religion”.

Invented in 1974 by Professor Erno Rubik, the Rubik’s cube was an instant success when it was first exported from Hungary in 1980, becoming the world’s fastest-selling toy.

The 64-year-old reclusive Hungarian professor has since seen his cube achieve 350 million sales in the three decades since.

Still obtaining a cult following, almost 40,000 entries on YouTube feature tutorials and video clips of quick solutions.

Last year the 360, a new game from the Rubik’s cube inventor went on sale.
