Bell Labs Is Leaving The Building

January 22, 2024 by Al Williams 21 Comments

If you ever had the occasion to visit Bell Labs at Murray Hill, New Jersey, or any of the nearby satellite sites, but you didn’t work there, you were probably envious. For one thing, some of the most brilliant people in the world worked there. Plus, there is the weight of history — Bell Labs had a hand in ten Nobel prizes, five Turing awards, 22 IEEE Medals of Honor, and over 20,000 patents, including several that have literally changed the world. They developed, among other things, the transistor, Unix, and a host of other high-tech inventions. Of course, Bell Labs hasn’t been Bell for a while — Nokia now owns it. And Nokia has plans to move the headquarters lab from its historic Murray Hill campus to nearby New Brunswick. (That’s New Jersey, not Canada.)

If your friends aren’t impressed by Nobels, it is worth mentioning the lab has also won five Emmy awards, a Grammy, and an Academy award. Not bad for a bunch of engineers and scientists. Nokia bought Alcatel-Lucent, who had wound up with Bell Labs after the phone company was split up and AT&T spun off Lucent.

Hardware Should Lead Software, Right?

January 20, 2024 by Elliot Williams 26 Comments

Once upon a time, about twenty years ago, there was a Linux-based router, the Linksys WRT54G. Back then, the number of useful devices running embedded Linux was rather small, and this was a standout. Back then, getting a hacker device that wasn’t a full-fledged computer onto a WiFi network was also fairly difficult. This one, relatively inexpensive WiFi router got you both in one box, so it was no surprise that we saw rovers with WRT54Gs as their brains, among other projects.

Of course, some people just wanted a better router, and thus the OpenWRT project was born as a minimal Linux system that let you do fancy stuff with the stock router. Years passed, and OpenWRT was ported to newer routers, and features were added. Software grew, and as far as we know, current versions won’t even run on the minuscule RAM of the original hardware that gave it it’s name.

Enter the ironic proposal that OpenWRT – the free software group that developed their code on a long-gone purple box – is developing their own hardware. Normally, we think of the development flow going the other way, right? But there’s a certain logic here as well. The software stack is now tried-and-true. They’ve got brand recognition, at least within the Hackaday universe. And in comparison, developing some known-good hardware to work with it is relatively easy.

We’re hardware hobbyists, and for us it’s often the case that the software is the hard part. It’s also the part that can make or break the user experience, so getting it right is crucial. On our hacker scale, we often choose a microcontroller to work with a codebase or tools that we want to use, because it’s easier to move some wires around on a PCB than it is to re-jigger a software house of cards. So maybe OpenWRT’s router proposal isn’t backwards after all? How many other examples of hardware designed to fit into existing software ecosystems can you think of?

USB-C PD: New Technology Done Right

January 15, 2024 by Jenny List 42 Comments

There is a tendency as we get older, to retreat into an instinctive suspicion of anything new or associated with young people. All of us will know older people who have fallen down this rabbit hole, and certainly anything to do with technological advancement is often high on their list of ills which beset society. There’s a Douglas Adams passage which sums it up nicely:

“I’ve come up with a set of rules that describe our reactions to technologies:
1. Anything that is in the world when you’re born is normal and ordinary and is just a natural part of the way the world works.
2. Anything that’s invented between when you’re fifteen and thirty-five is new and exciting and revolutionary and you can probably get a career in it.
3. Anything invented after you’re thirty-five is against the natural order of things.”

Here at Hackaday we’re just like anybody else, in that we all get older. Our lives are devoted to an insatiable appetite for new technology, but are we susceptible to the same trap, and could we see something as against the antural order of things simply because we don’t like it? It’s something that has been on my mind in some way since I wrote a piece back in 2020 railing at the ridiculous overuse of new technologies to limit the lifespan and repairability of new cars and then a manifesto for how the industry might fix it, am I railing against it simply because I can’t fix it with a screwdriver in the way I could my 1960 Triumph Herald? I don’t think so, and to demonstrate why I’d like to talk about another piece of complex new technology that has got everything right.

In 2017 I lamented the lack of a universal low voltage DC power socket that was useful, but reading the piece here in 2024 it’s very obvious that in the years since my quest has been solved. USB Power Delivery was a standard back then, but hadn’t made the jump to the ubiquity the USB-C-based power plug and socket enjoys today. Most laptops still had proprietary barrel jack connectors, and there were still plenty of phones with micro-USB sockets. In the years since it’s become the go-to power standard, and there are a huge number of modules and devices to supply and receive it at pretty high power.

At first sight though, it might seem as though USB-PD is simply putting a piece of unnecessary technology in the way of what should be a simple DC connector. Each and every USB-PD connection requires some kind of chip to manage it, to negotiate the connection, and to transform voltage. Isn’t that the same as the cars, using extra technology merely for the sake of complexity? On the face of it you might think so, but the beauty lies in it being a universally accepted standard. If car manufacturers needed the same functionalty you’d have modules doing similar things in a Toyota, a Ford, or a Renault, but they would all be proprietary and they’d be eye-wateringly expensive to replace. Meanwhile USB-PD modules have to work with each other, so they have become a universal component available for not a huge cost. I have several bags of assorted modules in a box of parts here, and no doubt you do too. The significant complexity of the USB-PD endpoint doesn’t matter any more, because should it break then replacing it is an easy and cheap process.

This is not to say that USB-PD is without its problems though, the plethora of different cable standards is its Achilies’ heel. But if you’re every accused of a knee-jerk reaction to a bad piece of new technology simply because it’s new, point them to it as perhaps the perfect example of the responsible use of new technology.

New Year’s Resolutions

January 6, 2024 by Elliot Williams 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 Jenny List 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 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.
