Happy Ada Lovelace Day!

October 10, 2017 by 74 Comments

Today is Ada Lovelace Day, a day to celebrate and encourage women in the fields of science and technology. The day is named after Augusta Ada King-Noel, Countess of Lovelace, born Byron. (You can see why we just call her Ada Lovelace.) She was a brilliant mathematician, and the writer of what’s probably the first real computer program — it computed the Bernoulli series. At least according Charles Babbage, in correspondence to Michael Faraday, she was an “enchanted math fairy”. Not only a proto-coder, she wrote almost all of the existing documentation about Babbage’s computation engine. She’s a stellar example of a brilliant and unique individual. If you were looking for a superhero to represent women in science and tech, Ada’s a good pick.

In our minds, she gets stiff competition from Marie Curie. Curie did fundamental research on radioactivity, is one of two people with Nobel Prizes in two different sciences, and got to name the two elements that she discovered. 2011 was the Year of Marie Curie in France and Poland. She has her own year in addition to her own unit. Even Spiderman doesn’t have those radioactive super powers!

Don’t Need Another Hero?

But on a day dedicated to getting more women into the technical arts, it’s also a little bit daunting to pick Lovelace or Curie as a symbol. Are you ever going to have something that equals “first computer program” or “two Nobel Prizes” on your résumé? We aren’t. It’s great to have heroes, but maybe we need more than just heroes — we also need mentors.

Our Reactions To The Treatment Of Robots

October 9, 2017 by 80 Comments

Most of us have seen employees of Boston Dynamics kicking their robots, and many of us instinctively react with horror. More recently I’ve watched my own robots being petted, applauded for their achievements, and yes, even kicked.

Why do people react the way they do when mechanical creations are treated as if they were people, pets, or worse? There are some very interesting things to learn about ourselves when considering the treatment of robots as subhuman. But it’s equally interesting to consider the ramifications of treating them as human.

The Boston Dynamics Syndrome

Atlas being pushed
Spot being kicked

Shown here are two snapshots of Boston Dynamics robots taken from their videos about Spot and Atlas. Why do scenes like this create the empathic reactions they do? Two possible reasons come to mind. One is that the we anthropomorphize the human-shaped one, meaning we think of it as human. That’s easy to do since not only is it human-shaped but the video shows it carrying a box using human-like movements. The second snapshot perhaps evokes the strongest reactions in anyone who owns a dog, though its similarity to any four-legged animal will usually do.

Is it wrong for Boston Dynamics, or anyone else, to treat robots in this way? Being an electronic and mechanical wizard, you might have an emotional reaction and then catch yourself with the reminder that these machines aren’t conscious and don’t feel emotional pain. But it may be wrong for one very good reason.

A 3D Printer Alone Doesn’t Make A Hackspace

October 5, 2017 by 75 Comments

There was a time when hackspaces were few and far between — legendary environments that you’d read about online, where amazing projects were made by people who had come together to form communities of creative technology enthusiasts. Of course, they were always in places far afield, California, or Germany, never in provincial England where I call home. Eventually our movement spread its tentacles into the county towns, and several years later with a stint as a hackspace director behind me I sense that it is on the cusp of escaping its underground roots. Every month seems to bring news of yet another organisation wanting to open a makerspace of their own, be they universities, co-working spaces, enterprise centres, libraries, or even banks. It’s evident that our movement has attracted an aura of edginess when it comes to getting things done, and that these entities are anxious to secure a little piece of that for themselves.

So within a few miles of most hackspaces will be several places where you can find a 3D printer, maybe a vinyl cutter, a CAD workstation, and a soldering iron. There will be a fancy hipster coffee machine and some futuristic furniture, and probably some kind of enclosed meeting pod of dubious design. All of which can no doubt be viewed through a glass wall, so that people in suits can watch all that raw #innovation sizzling away.

Viewed from within the movement, it’s easy to see all this activity on the edges of the world of making as a threat. A struggling community organisation survives on its wits alone, it doesn’t have a multi-million pound (or dollar) university or investor behind it. Its tools are hard-won and patched up, and its coffee machine is a battered electric kettle and a jar of supermarket instant coffee. When it comes to gleaming innovation spaces, a group of assorted makers simply can’t compete. Surely the arrival of these spaces will tempt members away, and the hackspace will inevitably wither, and die.

It’s worth taking a step back at this point, and considering what makes a hackspace. Specifically, what makes a good hackspace.

The Art Of Blinky Business Cards

October 4, 2017 by 42 Comments

Business cards are stuck somewhere between antiquity and convenience. On one hand, we have very convenient paperless solutions for contact swapping including Bluetooth, NFC, and just saying, “Hey, put your number into my phone, please.” On the other hand, holding something from another person is a more personal and memorable exchange. I would liken this to the difference between an eBook and a paperback. One is supremely convenient while the other is tactile. There’s a reason business cards have survived longer than the Rolodex.

Protocols and culture surrounding the exchange of cards are meant to make yourself memorable and a card which is easy to associate with you can work long after you’ve given your card away. This may seem moot if you are assigned cards when you start a new job, but personal business cards are invaluable for meeting people outside of work and you are the one to decide how wild or creative to make them.

We’re Using The Word Firmware Wrong

September 29, 2017 by 123 Comments

I had an interesting discussion the other day about code written for an embedded system. I was speaking with Voja Antonic about ‘firmware’. The conversation continued forward but I noticed that he was calling it ‘software’. We later discussed it and Voja told me he thought only the parts of the code directly interacting with the microcontroller were firmware; the rest falls under the more generic term of software. It really had me wondering where firmware stops being firmware and is merely software?

The topic has remained on my mind and I finally got around to doing some dictionary searches. I’m surprised that I’ve been using the word differently and I think most of the people I’ve heard use it are doing the same — at least as far as dictionary definitions are concerned. My go to sources are generally Merriam-Webster and Oxford English dictionaries and both indicate that firmware is a type of software that is indelible:

Permanent software programmed into a read-only memory.

computer programs contained permanently in a hardware device (such as a read-only memory)

According to this definition, I have never written a single bit of firmware. Everything I have written has been embedded software. But surely this is a term that must change with the times as technology progress so I kept digging.

The Engineering That Survives Hurricanes

September 27, 2017 by 84 Comments

Florida is a great place to live, especially around January when it’s sunny and 24 degrees outside (76F) while all of your friends from back home are dealing with scraping ice off of their windshields every morning. In the late summer, though, this pleasant tropical paradise can sometimes take a turn for the worse, because Florida is one of the handful of places that frequently see some of the worst storms on the planet: hurricanes. As a Floridian myself, perhaps I can shed some light on some of the ways that the various local governments and their residents have taken to mitigate the destruction that usually accompanies these intense tropical storms when it seems that, to outsiders, it might be considered unwise to live in such a place.

The Electronics Markets Of Ho Chi Minh City, Vietnam

September 25, 2017 by 56 Comments

When we think about world-famous electronics markets in Asia, usually Shenzhen, Tokyo’s Akihabara, or Shanghai’s Beijing Road come to mind.

There’s another market that I’ve had my eye on for a few years: Nhật Tảo market in Ho Chi Minh City, Vietnam. It might not be as large or accessible as the more well-known markets, but it’s very much worth a visit if you’re in the area. I decided it was time to hop on my red motorbike (red things go faster) and give you a short tour of the central market, as well as some more hobbyist-friendly options.
