I Want To Believe: How To Make Technology Value Judgements

November 15, 2024 by Jenny List 70 Comments

In the iconic 1990s TV series The X Files, David Duchovny’s FBI agent-paranormal investigator Fox Mulder has a poster on his office wall. It shows a flying saucer in flight, with the slogan “I Want To Believe”. It perfectly sums up the dilemma the character faces. And while I’m guessing that only a few Hackaday readers have gone down the full lizard-people rabbit hole, wanting to believe is probably something that a lot of us who love sci-fi understand. It would be a fascinating event for science if a real extraterrestrial craft would show up, so of course we want to believe to some extent, even if we’re not seriously expecting it to appear in a Midwestern cornfield and break out the probes any time soon.

By All Means Believe. But Don’t Wreck Your Career

The first page of a scientific paper: "Electrochemically induced nuclear fusion of deuterium". — The infamous Fleischmann and Pons paper from 1989 on cold fusion.

Outside the realm of TV drama and science fiction it’s a sentiment that also applies in more credible situations. Back at the end of the 1980s for example when so-called cold fusion became a global story it seemed as though we might be on the verge of the Holy Grail of clean energy breakthroughs. Sadly we never got our Mr. Fusion to power our DeLorean, and the scientific proof was revealed to be on very weak foundations. The careers of the two researchers involved were irreparably damaged, and the entire field became a byword for junk science. A more recently story in a similar vein is the EM drive, a theoretical reactionless force generator that was promising enough at one point that even NASA performed some research on it. Sadly there were no magic engines forthcoming, so while it was worth reporting on the initial excitement, we’re guessing the story won’t come back.

When evaluating a scientific or technical breakthrough that seems as miraculous as it is unexpected then, of course we all want to believe. We evaluate based on the information we have in front of us though, and we all have a credibility pyramid. There’s nothing wrong with having an interest in fields that are more hope than delivery, indeed almost every technology that powers our world will at some time have to overcome skepticism in its gestation period. Perhaps it’s best to say that it’s okay to have hope, but hope shouldn’t override our scrutiny of the proof. Of course I want a perpetual motion machine, who wouldn’t, but as a fictional engineer once allegedly said, “Ye cannae change the laws of physics”.

Ask Hackaday, What’s Next?

September 6, 2024 by Jenny List 39 Comments

Writing for Hackaday involves drinking from the firehose of tech news, and seeing the latest and greatest of new projects and happenings in the world of hardware. But sometimes you sit back in a reflective mood, and ask yourself: didn’t this all used to be more exciting? If you too have done that, perhaps it’s worth considering how our world of hardware hacking is fueled, and what makes stuff new and interesting.

Hardware projects are like startup fads

An AliExpress page of Nixie clock kits — When AliExpress has hundreds of kits for them, Nixie clocks are a mature project sector, by any measure.

Hardware projects are like startup fads, they follow the hype cycle. Take Nixie clocks for instance, they’re cool as heck, but here in 2024 there’s not so much that’s exciting about them. If you made one in 2010 you were the talk of the town, in 2015 everyone wanted one, but perhaps by 2020 yours was simply Yet Another Nixie Clock. Now you can buy any number of Nixie clock kits on Ali, and their shine has definitely worn off. Do you ever have the feeling that the supply of genuinely new stuff is drying up, and it’s all getting a bit samey? Perhaps it’s time to explore this topic.

I have a theory that hardware hacking goes in epochs, each one driven by a new technology. If you think about it, the Arduino was an epoch-defining moment in a readily available and easy to use microcontroller board; they may be merely a part and hugely superseded here in 2024 but back in 2008 they were nothing short of a revolution if you’d previously has a BASIC Stamp. The projects which an Arduino enabled produced a huge burst of creativity from drones to 3D printers to toaster oven reflow and many, many, more, and it’s fair to say that Hackaday owes its early-day success in no small part to that little board from Italy. To think of more examples, the advent of affordable 3D printers around the same period as the Arduino, the Raspberry Pi, and the arrival of affordable PCB manufacture from China were all similar such enabling moments. A favourite of mine are the Espressif Wi-Fi enabled microcontrollers, which produced an explosion of cheap Internet-connected projects. Suddenly having Wi-Fi went from a big deal to built-in, and an immense breadth of new projects came from those parts. Continue reading “Ask Hackaday, What’s Next?” →

VAR Is Ruining Football, And Tech Is Ruining Sport

April 29, 2024 by Lewin Day 84 Comments

Another week in football, another VAR controversy to fill the column inches and rile up the fans. If you missed it, Coventry scored a last-minute winner in extra time in a crucial match—an FA Cup semi-final. Only, oh wait—computer says no. VAR ruled Haji Wright was offside, and the goal was disallowed. Coventry fans screamed that the system got it wrong, but no matter. Man United went on to win and dreams were forever dashed.

Systems like the Video Assistant Referee were brought in to make sport fairer, with the aim that they would improve the product and leave fans and competitors better off. And yet, years later, with all this technology, we find ourselves up in arms more than ever.

It’s my sincere belief that technology is killing sport, and the old ways were better. Here’s why. Continue reading “VAR Is Ruining Football, And Tech Is Ruining Sport” →

Ask Hackaday: Why Are Self-Checkouts Failing?

January 16, 2024 by Al Williams 260 Comments

Most people who read Hackaday have positive feelings about automation. (Notice we said most.) How many times have you been behind someone in a grocery store line waiting for them to find a coupon, or a cashier who can’t make change without reading the screen and thought: “There has to be a better way.” The last few years have seen that better way, but now, companies are deciding the grass isn’t greener after all. The BBC reports that self-checkouts have been a “spectacular failure.” That led us to wonder why that should be true.

As a concept, everyone loves it. Stores can hire fewer cashiers. Customers, generally, like having every line open and having a speedy exit from the store. The problem is, it hasn’t really panned out that way. Self-checkout stations frequently need maintenance, often because it can’t figure out that you put something in the bag. Even when they work flawlessly, a customer might have an issue or not understand what to do. Maybe you’ve scanned something twice and need one of them backed off. Then, there are the age-restricted products that require verification. So now you have to hire a crew of not-cashiers to work at the automated not-register. Sure, you can have one person cover many registers, but when one machine is out of change, another won’t print a receipt, and two people are waiting for you to verify their beer purchase, you are back to waiting. Next thing you know, there’s a line.

A Few Reasonable Rules For The Responsible Use Of New Technology

January 3, 2024 by Jenny List 96 Comments

If there’s one thing which probably unites all of Hackaday’s community, it’s a love of technology. We live to hear about the very latest developments before anyone else, and the chances are for a lot of them we’ll all have a pretty good idea how they work. But if there’s something which probably annoys a lot of us the most, it’s when we see a piece of new technology misused. A lot of us are open-source enthusiasts not because we’re averse to commercial profit, but because we’ve seen the effects of monopolistic practices distorting the market with their new technologies and making matters worse, not better. After all, if a new technology isn’t capable of making the world a better place in some way, what use is it?

It’s depressing then to watch the same cycle repeat itself over and over, to see new technologies used in the service of restrictive practices for short-term gain rather than to make better products. We probably all have examples of new high-tech products that are simply bad, that are new technology simply for the sake of marketing, and which ultimately deliver something worse than what came before, but with more bling. Perhaps the worst part is the powerlessness, watching gullible members of the public lapping up something shiny and new that you know to be flawed, and not being able to do anything about it.

Here at Hackaday though, perhaps there is something I can do about it. I don’t sit in any boardroom that matters but I do have here a soapbox on which to stand, and from it I can talk to you, people whose work takes you into many fascinating corners of the tech industry and elsewhere. If I think that new technologies are being used irresponsibly to create bad products, at least I can codify how that might be changed. So here are my four Rules For The Responsible Use Of New Technology, each with some examples. They should each be self-evident, and I hope you’ll agree with me.

The Case For A Technology Aware Lobby Correspondent

November 17, 2023 by Jenny List 24 Comments

We cover all manner of stories here at Hackaday, including awesome hardware hacks, the latest trends and inventions, and in-depth guides to fascinating technologies. We also cover a few news stories from the wider world outside our community, usually when they have some knock-on effect that has an impact on us. Recently this last category of stories has included laws which present a threat to online encryption and privacy in the UK and in the European Union, for example. They’re not the most joyful of news, but it’s vital for everyone with an interest in online matters to be informed about them.

A Long And Inglorious History

Those of us who have followed the world of technology will know that badly thought out laws with a negative impact on technology have a long and inglorious history. Some like the infamous backdoored Clipper chip encryption device die an inglorious death as industry or the public succeed in making them irrelevant, but others such as the Digital Millennium Copyright Act or DMCA live on for decades and present an ongoing malign influence. Most recently our ongoing coverage of dubious drone stories included a hefty dose of equally dubious action from lawmakers.

When considering these pieces of legislation it’s easy to characterise the politicians who advance them as gullible idiots easily swayed by any commercial lobbyist with a fistful of cash. But the reality is far more nuanced, while some of them may well be tempted by those lobbyists they are in most cases neither gullible nor foolish. Instead they are better characterised as clueless on technical issues, and thus easily swayed by received opinion rather than by technological reality. If there’s a fault in the system it’s that the essential feedback which provides the checks and balances is missing, and oddly while sitting here writing this story, the responsibility for this comes close to home. The solution doesn’t lie in changing the politicians, but in changing how they are treated by journalists. Continue reading “The Case For A Technology Aware Lobby Correspondent” →

EV Chargers Could Be A Serious Target For Hackers

November 28, 2022 by Lewin Day 56 Comments

Computers! They’re in everything these days. Everything from thermostats to fridges and even window blinds are now on the Internet, and that makes them all ripe for hacking.

Electric vehicle chargers are becoming a part of regular life. They too are connected devices, and thus pose a security risk if not designed and maintained properly. As with so many other devices on the Internet of Things, the truth is anything but.
