LOL So true

IBM and Ford and GM helped Hitler in the war. Did you know that fact? A quick google found this IBM's technology helped facilitate Nazi genocide through generation and tabulation of punch cards based upon national census data.

All you guys had it so good. I remember the old days with magentic tape, then floppies. Dinosaur tech Selectron tubes (1946) In 1946 RCA began developing the Selectron tube—an early form of random access storage that was never produced in a commercially viable form. The original Selectron tube measured 10 inches and could store 4096 bits but was expensive to build and therefore replaced in the market by the widely available core memory. Magnetic tape (1951-present) Introduced in the 1950s, magnetic tape revolutionalized the broadcast and recording industries. Made of magnetizable coating on a long, thin strip of plastic, magnetic tapes allowed unmatched amounts of data to be created, stored and rapidly accessed. Magnetic tape was the most popular means of storing data until the mid 1980s, since a single roll could store 1TB, or as much data as 10,000 punch cards.

A typical 90-minute cassette could store close to 700kB to 1MB of data per side of the tape. Compact Cassettes were used to store data in a few computers and remained popular until the late 1980s.

These drums were 16 inches long and spun at a rate of 12,500 revolutions per minute. One of IBM’s earliest computers, the IBM 650, was one of the first computers to utilize a magnetic drum. It was used to supply the IBM 650 with 10,000 characters of main memory.

In 1973, a disk of the same size was created with a storage capacity of 256kB and the ability to write new data. Since then, floppy disks have been created smaller but with more data storage. The average capacity of a floppy disk is around 1.44MB.

The 305 RAMAC stored its data on 50 24 inch magnetic disks. Since the introduction of the 305 RAMAC, hard drives have been under constant improvement. The first hard disk drive stored roughly 120,000 times more data than IBM’s RAMAC at 500GB. Today, hard drives are smaller, cheaper, faster and can store more data.

This type of disc is a home video format and the first commercial optical disc storage medium. It is not possible to store typical hard drive data on these discs, but it is feasible to store video and image data with greater quality than VHS tapes.

CDs were developed by SONY and Philips in 1979 and arrived at market in 1982. They were originally created exclusively to store sound recordings but have evolved to encompass data storage. Today, a standard CD can store 700MB of data. Photo credit: http://www.flickr.com/photos/dustpuppy/4805018/

LTT will be late though.

make your own case

I want to do metal, wood and plastic nothing bigger then 2'x2'

Why do you want everyone to explain their username?

Just wait a year

They will be late in doing so. How can someone run a business and be late?

Its a sine wave, and measures the complete frequency per unit of time (seconds).

Blue light stimulates your brain. Not good as an alarm clock or driving dash lights.

Yes I found that out too
