I received a call from an old friend today
We easily talked the time away
Sharing stories and laughter and smiles
All the way across the miles
Time well spent I would have to say
When I received a call from an old friend today.

WHICH MEMORY CARD SHOULD I USE?
With all the different SD (Secure Digital) memory cards on the market today, it can be a challenge deciding which card to buy.
A standard SD card has a maximum capacity of 2 GB of data. When the SDHC (High Capacity) card was introduced in 2006, the maximum capacity rose to 32GB. In this time and age of terabytes, there is the SDXC (eXtended Capacity) card, which was introduced in 2009 and can handle up to 2TB (terabytes). But like most new things, there are compromises, in that certain cards do not work in certain devices, and certain devices only accept certain cards. Basically, old media (standard SD cards) work in newer devices, but new media (SDXC cards) will not work correctly in older devices. This is how it works:
SD devices accepts standard SD card.
SDHC devices accept standard SD and SDHC cards.
SDXC devices accept standard SD, SDHC, and SDXC cards.
Standard SD cards work in SD, SDHC, and SDXC devices.
SDHC cards work in SDHC and SDXC devices.
SDXC cards work in SDXC devices.

With the introduction of the SDHC card, specifications were set requiring manufactures to label all cards with performance ratings. The older performance measurement was an x-rating, which is derived from the standard CD-ROM drive speed of 1.2Mbits per second. This unit of measurement can still be found on some cards. A standard SD card transfers data up to six times (6x) the rate of a CD-ROM or 7.2Mbits per second. Typically, the x-rating is based on the maximum speed that data can be transferred.

A standard SD card transfers data up to six times (6x) the rate of a CD-ROM or 7.2Mbits per second. Typically, the x-rating is based on the maximum speed that data can be transferred.
This is some of the common x-ratings:
6x rating has write speed of 7.2Mbits per second
13x rating has write speed of 16.0Mbits or 2MB per second
26x rating has write speed of 32.0Mbits or 4MB per second
40x rating has write speed of 48.0Mbits or 6MB per second
66x rating has write speed of 80.0Mbits or 10MB per second
133x rating has write speed of160.0Mbits or 20MB per second
200x rating has write speed of 240.0Mbits or 30MB per second
300x rating has write speed of 360.0Mbits or 45MB per second
The newer class rating measures the minimum sustained transfer rate measured in megabytes per second and is equal to 1MB per second (8Mbits per second). So a Class 2 card has a transfer speed of 2MB per second, a Class 4 card has a 4 MB per second speed, a Class 6 card has a 6 MB per second speed, and a Class 10 card has a 10MB per second speed.
The main difference between the two speed ratings is that the x-rating measures maximum transfer speed, whereas the class rating measures minimum transfer speed. Also the class rating is readable by most devices, so if the class rating is below a device’s minimum requirements for optimal performance, the device can issue a warning. For example, if a camcorder requires a minimum of Class 4 card for optimal performance, it might work with Class 2 card but with compromises to quality or possibly data corruption. Understanding these performance ratings will help you better determine which card will meet your needs.

WHY IS THERE A LABOR DAY HOLIDAY?
While watching the news today, I saw a reporter ask several people what Labor Day was, and unfortunately, no one could answer his question. I thought, we have a federal holiday, yet no one knows really why. What a shame. Time for a little history.
The first Labor Day was 128 years ago, on September 5, 1882 by the Central Labor Union in New York City. But it did not become a federal holiday until 1894.
On May 11, 1894 in Pullman, IL, approximately 3000 labor union workers went on strike against the railroad in retaliation to a reduction in wages. This strike later became known as the Pullman strike because several of these workers died at the hands of the US Military and US Marshalls. In order to avoid further conflict, President Grover Cleveland rushed the necessary legislature declaring a federal Labor Day holiday through congress with a unanimous vote only six days later.
And this, in a nutshell, is why we have a Labor Day holiday.
