The World Of Web Browsers Is In A Bad Way

There once was a man who invented a means for publishing scientific documents using hypertext. He made his first documents available from his NeXT cube, and a lot of the academics who saw them thought it was a great idea. They took the idea, expanded it, and added graphics, and pretty soon people who weren’t scientists wanted to use it too. It became the Next Big Thing, and technology companies new and old wanted a piece of the pie.

You all know the next chapter of this story. It’s the mid 1990s, and Microsoft, having been caught on the back foot after pursuing The Microsoft Network as a Compuserve and AOL competitor, did an about-turn and set out to conquer the Web. Their tool of choice was Microsoft Internet Explorer 3, which since it shipped with Windows 95 and every computer that mattered back then came with Windows 95, promptly entered a huge battle with Netscape’s Navigator browser. Web standards were in their infancy so the two browsers battled each other by manipulating the underlying technologies on which the Web relied. Microsoft used their “Embrace and extend” strategy to try to Redmondify everything, and Netscape got lost in the wilderness with Netscape 4, a browser on which nightmarish quirks were the norm. By the millennium it was Internet Explorer that had won the battle, and though some of the more proprietary Microsoft web technologies had fallen by the wayside, we entered the new decade in a relative monoculture.

A Few Reasonable Rules For The Responsible Use Of New Technology

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.

Don’t Give Up

I’m at Chaos Communication Congress this weekend, and it’s like being surrounded by the brightest, most creative, and being honest, nerdiest crowd imaginable. And that’s super invigorating.

But because of the pandemic, this is the first in-person conference in four years, and it’s been a rather unsettling time in-between. There are tons of unknowns and issues confronting us all, geeks or otherwise, at the moment. I know some people who have fallen prey to this general malaise, and become more or less cynical.

Especially in this context, watching a talk about an absolutely bravado hack, or falling into a conversation that sparks new ideas, can be inspiring in just the right way to pull one out of the slump. Every talk is naturally a success story — of course they are, otherwise they wouldn’t be up there presenting.

But all of the smaller interactions, the hey-why-didn’t-I-think-of-that moments or the people helping each other out with just the right trick, that give me the most hope. That’s because they are all around, and I’m sure that what I’m seeing is just the tip of the iceberg. So stick together, nerds, share your work, and don’t give up!

Can Google’s New AI Read Your Datasheets For You?

We’ve seen a lot of AI tools lately, and, of course, we know they aren’t really smart, but they sure fool people into thinking they are actually intelligent. Of course, these programs can only pick through their training, and a lot depends on what they are trained on. When you use something like ChatGPT, for example, you assume they trained it on reasonable data. Sure, it might get things wrong anyway, but there’s also the danger that it simply doesn’t know what you are talking about. It would be like calling your company’s help desk and asking where you left your socks — they simply don’t know.

We’ve seen attempts to have AI “read” web pages or documents of your choice and then be able to answer questions about them. The latest is from Google with NotebookLM. It integrates a workspace where you can make notes, ask questions, and provide sources. The sources can be text snippets, documents from Google Drive, or PDF files you upload.

You can’t ask questions until you upload something, and we presume the AI restricts its answers to what’s in the documents you provide. It still won’t be perfect, but at least it won’t just give you bad information from an unknown source. Continue reading “Can Google’s New AI Read Your Datasheets For You?”

Ask Hackaday: Could Rating Airlines Stop Flights From Spreading Diseases?

 

A few weeks ago, I found myself the victim of flights from hell. My first flight was cancelled, leaving me driving home late at night, only to wake again for a red-eye the next morning. That was cancelled as well, with the second replacement delayed by a further hour. All in all I ended up spending a good ten hours extra in the airport surrounded by tired, sick, and coughing individuals, and ended up a full 16 hours late to my destination. On the return, I’d again tangle with delays, and by the weekend’s close, I’d contracted a nasty flu for my trouble.

All this had me riled up and looking for revenge. I had lost hours of my life to these frustrations, and the respiratory havoc claimed a further week of my working life. It had me realizing that we could surely improve the performance and hygiene of our airliners with a simple idea: a website called Flights From Hell.

The Physics Lesson I Keep Re-Learning

One of the most broadly applicable ideas I’ve ever encountered is the concept of impedance matching. If you’re into radio frequency electronics, you’re probably thinking that I mean getting all your circuit elements working to a common characteristic resistance for maximum power transfer. (If you’re not, you’re probably wondering what that jumble of words even means. Fear not!)

But I mean impedance matching in the larger sense. Think about driving a stick-shift automobile. In low gear, the engine has a lot of torque on the wheels, but it can’t spin them all that fast. In high, the wheels turn fastest, but there’s not enough torque to get you started from a standstill. Sometimes you need more force and less motion, other times more motion and less force. The gearbox lets you match the motor’s power to the resistance – the impedance – it’s trying to overcome.

Or think about a cello. The strings are tight, and vibrate with quite a bit of force, but they don’t move all that much. Air, which is destined to carry the sound to your ear, doesn’t take much force to move, and the cello would play louder if it moved more of it. So the bridge conveys the small, but strong, vibrations of the strings and pushes against the top of the resonant box that makes up the body of the instrument. This in turn pushes a lot of air, but not very hard. This is also why speakers have cones, and also why your ear has that crazy stirrup mechanism. Indeed, counting the number of impedance matches between Yo Yo Ma and your brain, I come up with four or five, including electrical matches in the pre-amp.

I mention this because I recently ran into a mismatch. Fans blow air either hard or in large volume. If you pick a fan that’s designed for volume, and put it in a pressure application, it’s like trying to start driving in fifth gear. It stalled, and almost no air got pushed up through the beans in my new “improved” coffee roaster, meaning I had to rebuild it with the old fan, and quick before the next cup was due.

I ran into this mismatch even though I knew there was a possible impedance issue there. I simply don’t have a good intuitive feel how much pressure I needed to push the beans around – the impedance in question – and I bought the wrong fan. But still, knowing that there is a trade-off is a good start. I hope this helps you avoid walking in my footsteps!

Thanks For Hacking

Hope you’re all having a great Thanksgiving weekend, and are getting your fill of family, food, and maybe even a little bit of fun. Aside from the cranberries, Thanksgiving is probably one of my favorite holidays because of the spirit behind it – thinking about what’s gone well, how you lucked out, and who has done you right over the year.

One of the most poignant expressions of thanks I’ve heard in a while came from Hackaday superfriend [Sprite_tm] in his Supercon talk this year, which he closed by thanking “you all” for pushing him on to keep making crazy projects. “I would never finish these projects without people who would be entertained by seeing all this. This is is effectively art – something that doesn’t make sense. The only way it makes sense is because I want it to exist, and because I know that you all love hearing and reading about stuff like this existing. So thank you very much for that.”

That same sentiment goes for all of us here at Hackaday: Thank you all very much for reading! Without this global community of crazy hackers to write for, we wouldn’t be able to keep doing what we do – it just wouldn’t make sense. And without your hacks, of course, we’d have nothing to write about.

Thanks for sharing, thanks for following along, thanks for inspiring us and for being inspired. Thanks for hacking.
