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”.

The Rogue Emperor, And What To Do About Them

November 8, 2024 by Jenny List 134 Comments

The chances are if you know someone who is a former Apple employee, you’ll have heard their Steve Jobs anecdote, and that it was rather unflattering to the Apple co-founder. I’ve certainly heard a few myself, and quick web search will reveal plenty more. There are enough of them that it’s very easy to conclude the guy was not a very pleasant person at all.

At the same time, he was a person whose public persona transcended reality, and his fan base treated him with an almost Messianic awe. For them everything he touched turned to gold, every new feature on an Apple product was his personal invention, every one of his actions even the not-so-clever ones were evidence of his genius, and anyone who hadn’t drunk the Apple Kool-Aid was anathema. You’ll still see echoes of this today in Apple fanboys, even though the shine on the company is perhaps now a little tarnished.

It’s easy to spot parallels to this story in some of today’s tech moguls who have gathered similar devotion, but it’s a phenomenon by no means limited to tech founders. Anywhere there is an organisation or group that is centred around an individual, from the smallest organisation upwards, it’s possible for it to enter an almost cult-like state in which the leader both accumulates too much power, and loses track of some of the responsibilities which go with it. If it’s a tech company or a bowls club we can shrug our shoulders and move to something else, but when it occurs in an open source project and a benevolent dictator figure goes rogue it has landed directly on our own doorstep as the open-source community. It’s happened several times that I can immediately think of and there are doubtless more cases I am unaware of, and every time I am left feeling that our community lacks an adequate mechanism to come through it unscathed.

Ham Radio In The Internet Age

October 25, 2024 by Al Williams 66 Comments

Even if you are relatively young, you can probably think back on what TV was like when you were a kid and then realize that TV today is completely different. Most people watch on-demand. Saturday morning cartoons are gone, and high-definition digital signals are the norm. Many of those changes are a direct result of the Internet, which, of course, changed just about everything. Ham radio is no different. The ham radio of today has only a hazy resemblance to the ham radio of the past. I should know. I’ve been a ham for 47 years.

You know the meme about “what people think I do?” You could easily do that for ham radio operators. (Oh wait, of course, someone has done it.) The perception that hams are using antique equipment and talking about their health problems all day is a stereotype. There are many hams, and while some of them use old gear and some of them might be a little obsessed with their doctor visits, that’s true for any group. It turns out there is no “typical” ham, but modern tech, globalization, and the Internet have all changed the hobby no matter what part of it you enjoy.

Radios

One of the biggest changes in the hobby has been in the radio end. Hams tend to use two kinds of gear: HF and VHF/UHF (that’s high frequency, very high frequency, and ultra-high frequency). HF gear is made to talk over long distances, while VHF/UHF gear is for talking around town. It used to be that a new radio was a luxury that many hams couldn’t afford. You made do with surplus gear or used equipment.

Globalization has made radios much less expensive, while technological advances have made them vastly more capable. It wasn’t long ago that a handy-talkie (what normal folks would call a walkie-talkie) would be a large purchase and not have many features. Import radios are now sophisticated, often using SDR technology, and so cheap that they are practically disposable. They are so cheap now that many hams have multiples that they issue to other hams during public service events.

Hackaday Hacked!

October 19, 2024 by Elliot Williams 206 Comments

Well, that was “fun”. Last week, we wrote a newsletter post about the state of Hackaday’s comments. We get good ones and bad ones, and almost all the time, we leave you all up to your own devices. But every once in a while, it’s good to remind people to be nice to our fellow hackers who get featured here, because after all they are the people doing the work that gives us something to read and write about. The whole point of the comment section is for you all to help them, or other Hackaday readers who want to follow in their footsteps.

Someone decided to let loose a comment-reporting attack. It works like this: you hit the “report comment” button on a given comment multiple times from multiple different IP addresses, and our system sends the comments back to moderation until a human editor can re-approve them. Given the context of an article about moderation, most everyone whose comment disappeared thought that we were behind it. When more than 300 comments were suddenly sitting in the moderation queue, our weekend editors figured something was up and started un-flagging comments as fast as they could. Order was eventually restored, but it was ugly for a while.

We’ve had these attacks before, but probably only a handful of times over the last ten years, and there’s basically nothing we can do to prevent them that won’t also prevent you all from flagging honestly abusive or spammy comments. (For which, thanks! It helps keep Hackaday’s comments clean.) Why doesn’t it happen all the time? Most of you all are just good people. Thanks for that, too!

But despite the interruption, we got a good discussion started about how to make a comment section thrive. A valid critique of our current system that was particularly evident during the hack is that the reported comment mechanism is entirely opaque. A “your comment is being moderated” placeholder would be a lot nicer than simply having the comment disappear. We’ll have to look into that.

You were basically divided down the middle about whether an upvote/downvote system like on Reddit or Slashdot would serve us well. Those tend to push more constructive comments up to the top, but they also create a popularity contest that can become its own mini-game, and that’s not necessarily always a good thing. Everyone seemed pretty convinced that our continuing to allow anonymous comments is the right choice, and we think it is simply because it removes a registration burden when someone new wants to write something insightful.

What else? If you could re-design the Hackaday comment section from scratch, what would you do? Or better yet, do you have any examples of similar (tech) communities that are particularly well run? How do they do it?

We spend our time either writing and searching for cool hacks, or moderating, and you can guess which we’d rather. At the end of the day, our comments are made up of Hackaday readers. So thanks to all of you who have, over the last week, thought twice and kept it nice.

If You Can’t Say Anything Nice

October 12, 2024 by Elliot Williams 398 Comments

[Editor’s Note: After we posted this, we got hit by a comment-report attack, and about 1,000 (!) comments across the whole site got sent back into the moderation queue on Saturday. We’ve since re-instated them all, but that took a lot of work.

About halfway down the comments in this article, the majority of comments are “hey, why did you delete this?” We didn’t, and they should be all good now. We debated removing the “try deleting this!” comments, but since we didn’t delete them in the first place, we thought we should just leave them. It makes a royal mess of any discussion, and created a lot more heat than light, which is unfortunate.]

You know what your mom would say, right? This week, we got an above average number of useless negative comments. A project was described as looking like a “turd” – for the record I love the hacker’s angular and futuristic designs, but it doesn’t have to be to your taste. Then someone else is like “you don’t even need a computer case.” Another commenter informed us that he doesn’t like to watch videos for the thirtieth time. (Yawn!)

What all of these comments have in common is that they’re negative, low value, non-constructive, and frankly have no place on Hackaday. The vast majority are just kind of Eeyorey complaining about how someone else is enjoying a chocolate ice cream, and the commenter prefers strawberry. But then some of them turn nasty. Why? If someone makes a project that you don’t like, they didn’t do it to offend you. Just move on quietly to one you do like. We publish a hack every three hours like a rubidium clockwork, with a couple of original content pieces scattered in-between on weekdays.

And don’t get us wrong: we love comments that help improve a project. There’s a not-so-fine line between “why didn’t you design it with trusses to better hold the load?” and “why did you paint it black, because blue is the superior color”. You know what we mean. Constructive criticism, good. Pointless criticism, bad.

It was to the point that we were discussing just shutting down the comments entirely. But then we got gems! [Maya Posch]’s fantastic explainer about the Lagrange points had an error: one of the satellites that Wikipedia said was at an earth-moon Lagrange point is actually in normal orbit around the moon. It only used the Lagrange point as a temporary transit orbit. Says who? One of the science instrument leads on the space vehicle in question. Now that is a high-value comment, both because it corrects a mistake and enlightens us all, but also because it shows who is reading Hackaday!

Or take [Al Williams]’s article on mold-making a cement “paper” airplane. It was a cool technique, but the commenters latched onto his assertion that you couldn’t fly a cement plane, and the discussions that ensued are awesome. Part of me wanted to remind folks about the nice mold-making technique on display, but it was such a joy to go down that odd rabbit hole, I forgive you all!

We have an official “be nice” policy about the comments, and that extends fairly broadly. We really don’t want to hear what you don’t like about someone’s project or the way they presented it, because it brings down the people out there who are doing the hard work of posting their hacks. And hackers have the highest priority on Hackaday.

Will You Need Ad Block For Your Car?

September 24, 2024 by Navarre Bartz 115 Comments

The modern web has become difficult to navigate without ad blocking software. Ford now has a patent application that would bring the ads we hate to your vehicle’s infotainment system. [via PCMag]

Ford has already replied to criticism with the usual corporate spiel of patents not necessarily being the direction the company will go with future products, but it’s hard to imagine that other automakers aren’t planning similar systems since they’re already charging extra for heated seats, EV range, and performance. Bringing ads to the captive audience of your personal vehicle and targeting them based on listening to the occupants’ conversations would be a new low. Maybe you’ll be able to pay an extra $100/month for the “ad-free experience.”

Instead of taking advantage of the EV transition to make better, simpler cars, automakers are using their highly-computerized nature to extract more from you and provide less when you drive off the lot. Enshittification has come for the automobile. Perhaps auto executives should read A Few Reasonable Rules for the Responsible Use of New Technology?

The first step of blocking these ads will likely be jailbraking the infotainment system. If that wasn’t enough, locking features behind a paywall has come for wheelchairs too.

Against Elitism

September 21, 2024 by Elliot Williams 104 Comments

A while back we got an anonymous complaint that Hackaday was “elitist”, and that got me thinking. We do write up the hacks that we find the coolest, and that could lead to a preponderance of gonzo projects, or a feeling that something “isn’t good enough for Hackaday”. But I really want to push back against that notion, because I believe it’s just plain wrong.

One of the most important jobs of a Hackaday writer is to find the best parts of a project and bring that to the fore, and I’d like to show you what I mean by example. Take this post from two weeks ago that was nominally about rescuing a broken beloved keyboard by replacing its brain with a modern microcontroller. On its surface, this should be easy – figure out the matrix pinout and wire it up. Flash in a keyboard firmware and you’re done.

Of course we all love a good hardware-rescue story, and other owners of busted Sculpt keyboards will be happy to see it. But there’s something here for the rest of us too! To figure out the keyboard matrix, it would take a lot of probing at a flat-flex cable, so [TechBeret] made a sweet breakout board that pulled all the signals off of the flat-flex and terminated them in nicely labelled wires. Let this be your reminder that making a test rig / jig can make these kind of complicated problems simpler.

Once the pinout was figured out, and a working prototype made, it was time to order a neat PCB and box it up. The other great trick was the use of 3D-printed mockups of the PCBs to make sure that they fit inside the case, the holes were all in the right places, and that the flat-flex lay flat. With how easily PCB design software will spit out a 3D model these days, you absolutely should take the ten minutes to verify the physical layout of each revision before sending out your Gerbers.

So was this a 1337 hack? Maybe not. But was it worth reading for these two sweet tidbits, regardless of whether you’re doing a keyboard hack? Absolutely! And that’s exactly the kind of opportunity that elitists shut themselves off from, and it’s the negative aspect of elitism what we try to fight against here at Hackaday.
