Computers That Never Were

Today it is easier than ever to learn how to program a computer. Everyone has one (and probably has several) and there are tons of resources available. You can even program entirely in your web browser and avoid having to install programming languages and other arcane software. But it wasn’t always like this. In the sixties and seventies, you usually learned to program on computers that didn’t exist. I was recently musing about those computers that were never real and wondering if we are better off now with a computer at every neophyte’s fingertips or if somehow these fictional computing …read more

Retrotechtacular: The Transistor (1953 Film)

If we cast our minds back to the early years of the transistor, the year that is always quoted is 1947, during which a Bell Labs team developed the first practical germanium point-contact transistor. They would go on to be granted the Nobel Prize for their work in 1956, but the universal adoption of their invention was not an instantaneous process. Instead there would be a gradual change from vacuum to solid state that would span the 1950s and the 1960s, and even in the 1970s you might still have found mainstream devices on sale containing vacuum tubes.

To speed …read more

Retrotechtacular: Farming Implements in 1932

Few people would deny that farming is hard work. It always has been, and it probably always will be no matter how fancy the equipment gets. In 1932, farming was especially grueling. There was widespread drought throughout the United States, which gave rise to dust bowl conditions. As if those two things weren’t bad enough, the average income of the American farmer fell to its lowest point during the Depression, thanks to the Smoot-Hawley Tariff Act.

Even so, crop farming was still a viable and somewhat popular career path in 1932. After all, knowing how to grow food is always …read more

Retrotechtacular: Stereo Records

The 20th century saw some amazing technological developments. We went from airplanes to the moon. We went from slide rules to digital computers. Crank telephones to cell phones. But two of the most amazing feats of that era were ones that non-technical people probably hardly think about. The transformation of radio and TV from mono and black and white, to stereo and color. What was interesting about both of these is that engineers managed to find a way to push the new better result into the same form as the old version and — this is the amazing part — …read more

Retrotechtacular: ERNIE

Wherever you may live in the world, who do you wish to smile upon you and deliver good fortune? You may be surprised to discover that for a significant number of Brits this role is taken by someone called [Ernie].

What, [Jim Henson]’s Ernie from Sesame Street‘s famous duo Bert and Ernie? Sadly not, because the owner of a [Rubber Duckie] can’t offer you the chance of a million quid every month. Instead, [Ernie] is a computer that has been anthropomorphised in the national imagination. More properly referred to as E.R.N.I.E, for Electronic Random Number I …read more

Retrotechtacular: The Mother Of All (British) Demos

One of the most famous lectures in the history of technology was delivered by [Douglas Engelbart] in December 1968, at a San Francisco conference. In it he described for the first time most of what we take for granted in our desktop computers and networking today, several years before even the first microprocessor made it to market. It is revered not only because it was the first airing of these ideas, but because it was the event that inspired and influenced many of those who developed them and brought them to market. You may have heard of it by its …read more

Retrotechtacular: Social Hacking is Nothing New

If you watch enough mainstream TV and movies, you might think that hacking into someone’s account requires a huge monitor, special software, and intricate hand gestures. The reality is way more boring. Because people tend to choose bad passwords, if you have time, you can task a computer with quietly brute-forcing the password. Then again, not everyone has a bad password and many systems will enforce a timeout after failed attempts or require two-factor authentication, so the brute force approach isn’t what it used to be.

Turns out the easiest way to get someone’s password is to ask them for …read more

Retrotechtacular: Rocket Sleds

If you need to test rockets, missiles, or ejection-seat systems, your first instinct would be to shoot them up in the air and see what happens. But if you want data, film footage, or the ability to simply walk away from a test, you might consider running your experiment on a rocket sled.

The Holloman High Speed Test Track is a 15 km long stretch of meticulously straight railroad track located in the middle of the New Mexico desert, and bristling with measurement equipment. Today’s Retrotechtacular video (embedded below) gives you the guided tour. And by the way, the elderly …read more

Retrotechtacular: Horseless Farming With The Ford Model B

Does everyone watch a load of videos on YouTube that are somewhat on the unadmissibly geeky side? In my case I might not care to admit that I have a lot of videos featuring tractors in my timeline. The mighty Russian Kirovets hauling loads through the impossible terrain of the taiga, tiny overloaded 2WD tractors in India pulling wheelies, and JCB Fastracs tearing around the British Fenland. You can take the girl off the farm, but you can’t take the farm out of the girl.

So my recommendations have something of an agricultural flavor. Like the video below the break, …read more

Retrotechtacular: Max Headroom Takes Chicago In Audacious TV Hack

Those of you with long memories and a compulsive TV viewing habit might remember [Max Headroom], a quirky piece of TV ephemera from the late 1980s and early 1990s. [Max] was a supposedly computer generated TV show host and VJ with a pseudomechanical stutter, a slightly blocky rendered head, and a moving background of rendered lines. He looks a little quaint for viewers with a few decades viewing experience of CGI, but in his day he was cutting-edge cypberpunk TV.

He also made unscheduled showings on two Chicago TV stations in an audacious hack that has never been …read more
