It’s The Simple Things

January 13, 2024 by 5 Comments

I love minimal hacks. Limitations are sometimes the spark for our greatest creativity, and seeing someone do something truly marvelous with the simplest of technological ingredients never fails to put a smile on my face.

This week, it was the super-simple 1D Fireworks project by [Daniel Westhof]. Nothing more than an ESP8266 and a long RGB LED strip went into this effect on the hardware side, and indeed the code isn’t all that tricky either. But what it does is a very nice simulation of the physics that define the movement of a flare rocket and then all of the stars that explode out of it. And that makes it look so good.

Hackaday’s [Kristina Panos] is apparently also a fan of the single dimension, because she picked out some of my personal favorite uses of an LED strip, including Twang, to which we’ll admit we’re addicted, or any of the PONG versions.

But I’ve seen other games, including a button-mashing racer and various roller-coaster simulations. All with the same, essentially, two-part BOM. (OK, if you don’t count the buttons/accelerometer, or power supply.) Or this demo of sorting routines, or the Velocicoaster. And I think there’s more out there.

How much creativity can you pack into an LED strip? This sounds like we need to make a new contest…

New Year’s Resolutions

January 6, 2024 by 18 Comments

As we stand here looking at the brand-new year ahead, we find ourselves taking stock, and maybe thinking how we can all be better people in the next year. More exercise, being nicer to your neighbors, consuming more or less of this or that, depending on whether it’s healthy or un. Those are the standard fare. But what’s your hacker new year’s resolution?

Mine, this year, is to branch out into a new microcontroller family, to learn a new toolchain, and maybe to finally dip my toes into Bluetooth Low Energy. Although that last one is admittedly a stretch.

But the former is great resolution material, if you allow me. New programming tooling is always a little unpleasant to set up, but there’s also payoff at the end of the ordeal. It’s a lot like picking up a new exercise – it makes you stronger. Or course, it helps to have an application in mind, the equivalent of that suit you want to be able to fit into at the end of the diet. I’ve got one. I’ve also been out of programming in straight C for a year or so, and I’m faced with a new HAL, so there’s bound to be enough of a challenge to make it worthwhile.

Honestly, I’m looking forward to getting started, but with the usual mix of optimism, over-optimism, and mild dread. It’s the perfect setup for a resolution! What’s yours?

(And yes, the art is from another story, but setting up a good backup regime isn’t a bad resolution either.)

The World Of Web Browsers Is In A Bad Way

January 4, 2024 by 115 Comments

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

January 3, 2024 by 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.

Don’t Give Up

December 30, 2023 by 29 Comments

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?

December 12, 2023 by 25 Comments

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?

December 6, 2023 by 82 Comments

 

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.
