Hearing aid

Seems an elderly gentleman had serious hearing problems for a number of years.

He went to the doctor and the doctor was able to have him fitted for a set of hearing aids that allowed the gentleman to hear 100%.

The elderly gentleman went back in a month to the doctor and the doctor said, "Your hearing is perfect. Your family must be really pleased you can hear again."

To which the gentleman said, "Oh, I haven’t told my family yet.

I just sit around and listen to the conversations.

I’ve changed my will three times!"

 

Chocolate Chip Cookies

The children were lined up in the cafeteria of a Catholic elementary school for lunch.

At the head of the table was a large pile of apples.

The nun made a note, and posted on the apple tray: "Take only ONE. God is watching."

Moving further along the lunch line, at the other end of the table was a large pile of chocolate chip cookies.

A child had written a note, "Take all you want. God is watching the apples”.

Complex Simplicities  

Blade server

A blade server is a stripped down server computer with a modular design optimized to minimize the use of physical space and energy. Whereas a standard rack-mount server can function with (at least) a power cord and network cable, blade servers have many components removed to save space, minimize power consumption and other considerations, while still having all the functional components to be considered a computer. A blade enclosure, which can hold multiple blade servers, provides services such as power, cooling, networking, various interconnects and management.

WiBro

WiBro (Wireless Broadband)is a wireless broadband Internet technology developed by the South Korean telecoms industry. WiBro is the South Korean service name for IEEE 802.16e (mobile WiMAX) international standard.

The Mauna Loa volcano in Hawaii holds the title here on Earth. It rises more than 50,000 feet (9.5 miles or 15.2 kilometers) above its base, which sits under the surface of the sea. But that's all volcanic chump change. Olympus Mons on Mars rises 16 miles (26 kilometers) into the Martian sky.
The record for the longest period without sleep is 18 days, 21 hours, 40 minutes during a rocking chair marathon. The record holder reported hallucinations, paranoia, blurred vision, slurred speech and memory and concentration lapses.
Adidas is a major German-based sports apparel manufacturer, producing not only footwear but also bags, shirts, eyewear and other goods, related to sports. The name of the company comes from the name and surname of its founder Adi Dassler. In 1949, he took the first two syllables from his first (Adi) and last name (das) to create the name for his line of athletic shoes. But there’s only another version referring to the meaning of the word. It’s said that ADIDAS means “All Day I Dream About Sports”.
All U.S. currency is made of 75 percent cotton and 25 percent linen. It’s closer to cloth than paper. This product is made by the Crane Company, which is based in Dalton, Mass. The Crane Company created the patent for this special paper for the Treasury in 1879.
Mars can whip up hurricane-like storms four times bigger than Texas. Dust storms on the red planet can obscure the entire globe! Jupiter has a hurricane twice the size our entire planet, and it’s lasted for at least three centuries (another storm on Jupiter is even bigger). Venus is a living hell, and Pluto is routinely more frigid than the coldest place on Earth (though may change one day, and Pluto may in fact become the last oasis for life).
 
 
Six Sigma
 
Introduction
Six Sigma is a business management strategy originally developed by Motorola, USA in 1981. Six Sigma seeks to improve the quality of process outputs by identifying and removing the causes of defects (errors) and minimizing variability in manufacturing and business processes. It uses a set of quality management methods, including statistical methods, and creates a special infrastructure of people within the organization ("Black Belts", "Green Belts", etc.) who are experts in these methods. Each Six Sigma project carried out within an organization follows a defined sequence of steps and has quantified financial targets (cost reduction or profit increase).
The term six sigma originated from terminology associated with manufacturing, specifically terms associated with statistical modelling of manufacturing processes. The maturity of a manufacturing process can be described by a sigma rating indicating its yield, or the percentage of defect-free products it creates. A six-sigma process is one in which 99.99966% of the products manufactured are statistically expected to be free of defects (3.4 defects per million). Motorola set a goal of "six sigmas" for all of its manufacturing operations, and this goal became a byword for the management and engineering practices used to achieve it.
Methods
Six Sigma projects follow a project methodologies inspired by Deming's Plan-Do-Check-Act Cycle. The methodologies, composed of five phases each, bear the acronyms DMAIC.
DMAIC is used for projects aimed at improving an existing business process. DMAIC is pronounced as "duh-may-ick".
DMAIC
The DMAIC project methodology has five phases:
Define the problem, the voice of the customer, and the project goals, specifically.
Measure key aspects of the current process and collect relevant data.
Analyze the data to investigate and verify cause-and-effect relationships. Determine what the relationships are, and attempt to ensure that all factors have been considered. Seek out root cause of the defect under investigation. .
Improve or optimize the current process based upon data analysis using techniques such as design of experiments, poka yoke or mistake proofing, and standard work to create a new, future state process. Set up pilot runs to establish process capability.
Control the future state process to ensure that any deviations from target are corrected before they result in defects. Implement control systems such as statistical process control, production boards, and visual workplaces, and continuously monitor the process.
Certification
In the United States, Six Sigma certification for both Green and Black Belts is offered by the Institute of Industrial Engineers and by the American Society for Quality.
In addition to these examples, there are many other organizations and companies that offer certification. There currently is no central certification body, either in the United States or anywhere else in the world.
 

Blade server

A blade server is a stripped down server computer with a modular design optimized to minimize the use of physical space and energy. Whereas a standard rack-mount server can function with (at least) a power cord and network cable, blade servers have many components removed to save space, minimize power consumption and other considerations, while still having all the functional components to be considered a computer. A blade enclosure, which can hold multiple blade servers, provides services such as power, cooling, networking, various interconnects and management. Together, blades and the blade enclosure form the blade system. (Different blade providers have differing principles regarding what to include in the blade itself, and in the blade system altogether.)
Blade servers function well for specific purposes such as web hosting, virtualization, and cluster computing. Individual blades are typically hot-swappable. As users add more processing power, memory and I/O bandwidth to blade servers, they deal with larger and more diverse workloads. Blade servers do not, however, provide the answer to every computing problem. One can view them as a form of productized server-farm that borrows from mainframe packaging, cooling, and power-supply technology. Very large computing tasks may still require server farms of blade servers, and because of blade servers' high power density, can suffer even more acutely from the HVAC problems that affect large conventional server farms.
While computers typically use hard disks to store operating systems, applications and data, these are not necessarily required locally. Many storage connection methods (e.g. FireWire, SATA, E-SATA, SCSI, DAS, Fibre Channel and iSCSI) are readily moved outside the server, though not all are used in enterprise-level installations. Implementing these connection interfaces within the computer presents similar challenges to the networking interfaces (indeed iSCSI runs over the network interface), and similarly these can be removed from the blade and presented individually or aggregated either on the chassis or through other blades.
The ability to boot the blade from a storage area network (SAN) allows for an entirely disk-free blade. This allows more board space to be devoted to extra memory or additional CPUs. Depending on vendors, some blade servers may include or exclude internal storage devices.
 
 

WiBro

WiBro(Wireless Broadband)is a wireless broadband Internet technology developed by the South Korean telecoms industry. WiBro is the South Korean service name for IEEE 802.16e (mobile WiMAX) international standard.

WiBro adopts TDD for duplexing, OFDMA for multiple access and 8.75 MHz as a channel bandwidth. WiBro was devised to overcome the data rate limitation of mobile phones (for example CDMA 1x) and to add mobility to broadband Internet access (for example ADSL or Wireless LAN). In February 2002, the Korean government allocated 100 MHz of electromagnetic spectrum in the 2.3 - 2.4 GHz band.
WiBro base stations will offer an aggregate data throughput of 30 to 50 Mbit/s per carrier and cover a radius of 1–5 km allowing for the use of portable internet usage. In detail, it will provide mobility for moving devices up to 120 km/h (74.5 miles/h) compared to Wireless LAN having mobility up to walking speed and mobile phone technologies having mobility up to 250 km/h. The technology will also offer Quality of Service.
