Now You Can Dial Your Own Telephone! (1954)

In this instructional AT&T film from 1954, host Susann Shaw explains how to dial your own telephone. This was, of course, to ease the transition from operator-assisted calls to dial service. It's bizarre to hear someone explain what a dial tone is, what a busy signal is, and how to dial a telephone -- though in fact all of these things will probably exist only in "classic movies" for kids being born today. Listen for the 1950's-era dial tone around the 2-minute mark and the busy signal around 6:50; they're both vaguely menacing. There's also discussion of the infamous "party line."

From the film's description:

The dial telephone was new at this point, although the two-letter, 5-number system was still commonplace. This film even has to explain what a ringing and busy signal sound like!

This film opens with the demonstrator pointing out the importance of correctly using the dial telephone. Correct dialing techniques are demonstrated, with an emphasis placed on the following:

1. Be sure of the right number

2. Wait for the dial tone

3. Refer to the number while dialing

4. Turn the dial until the finger hits the finger stop

5. Avoid confusing the letter "O" with the "0"

6. The difference between ringing and busy signals

At one point Shaw says: "You'll always find operators ready to help, whenever you need them!" Well...maybe in the 50's. Enjoy:

The World’s First 3D-Printed Opera Set Is Coming to Rome

In October, the Opera Theater in Rome will become the first theater to play host to a 3D-printed set in one of its operas. The theater’s performance of the 19th-century opera Fra Diavolo by French composer Daniel Auber, opening on October 8, will feature set pieces printed by the Italian 3D-printing company WASP, as TREND HUNTER reports.

Set designers have been using 3D printers to make small-scale set models for years, but WASP says this seems to be the first full 3D-printed set. (The company is also building a 3D-printed town elsewhere in Italy, to give you a sense of its ambitions for its technology.)

Designers stand around a white 3D-printed model of a theater set featuring warped buildings.

The Fra Diavolo set consists of what looks like two warped historic buildings, which WASP likens to a Dalí painting. These buildings are made of 223 smaller pieces. It took five printers working full-time for three months to complete the job. The pieces were sent to Rome in mid-July in preparation for the opera.

Recently, 3D printing is taking over everything from housing construction to breakfast. If you can make an office building with a printer, why not a theater set? (Though it should be noted that the labor unions that represent scenic artists might disagree.)

A Simple Way to Charge Your iPhone in 5 Minutes

Spotting the “low battery” notification on your phone is usually followed by a frantic search for an outlet and further stress over the fact that you may not have time for a full charge. On iPhones, plugging your device into the wall for five minutes might result in only a modest increase of about three percent or so. But this tip from Business Insider Tech may allow you to squeeze out a little more juice.

The trick? Before charging, put your phone in Airplane Mode so that you reduce the number of energy-sucking tasks (signal searching, fielding incoming communications) your device will try and perform.

Next, take the cover off if you have one (the phone might be generating extra heat as a result). Finally, try to use an iPad adapter, which has demonstrated a faster rate of charging than the adapter that comes with your iPhone.

Do that and you’ll likely double your battery boost, from about three to six percent. It may not sound like much, but that little bit of extra juice might keep you connected until you’re able to plug it in for a full charge.
