ChatGPT V. The Legal System: Why Trusting ChatGPT Gets You Sanctioned

Recently, an amusing anecdote made the news headlines pertaining to the use of ChatGPT by a lawyer. This all started when a Mr. Mata sued the airline where years prior he claims a metal serving cart struck his knee. When the airline filed a motion to dismiss the case on the basis of the statute of limitations, the plaintiff’s lawyer filed a submission in which he argued that the statute of limitations did not apply here due to circumstances established in prior cases, which he cited in the submission.

Unfortunately for the plaintiff’s lawyer, the defendant’s counsel pointed out that none of these cases could be found, leading to the judge requesting the plaintiff’s counsel to submit copies of these purported cases. Although  the plaintiff’s counsel complied with this request, the response from the judge (full court order PDF) was a curt and rather irate response, pointing out that none of the cited cases were real, and that the purported case texts were bogus.

The defense that the plaintiff’s counsel appears to lean on is that ChatGPT ‘assisted’ in researching these submissions, and had assured the lawyer – Mr. Schwartz – that all of these cases were real. The lawyers trusted ChatGPT enough to allow it to write an affidavit that they submitted to the court. With Mr. Schwartz likely to be sanctioned for this performance, it should also be noted that this is hardly the first time that ChatGPT and kin have been involved in such mishaps.

Hackaday Links: May 28, 2023

The Great Automotive AM Radio War of 2023 rages on, with the news this week that Ford has capitulated, at least for now. You’ll recall that the opening salvo came when the US automaker declared that AM radio was unusable in their EV offerings thanks to interference generated by the motor controller. Rather than fixing the root problem, Ford decided to delete the AM option from their EV infotainment systems, while letting their rolling EMI generators just keep blasting out interference for everyone to enjoy. Lawmakers began rattling their sabers in response, threatening legislation to include AM radio in every vehicle as a matter of public safety. Ford saw the writing on the wall and reversed course, saying that AM is back for at least the 2024 model year, and that vehicles already delivered without it will get a fix via software update.

3D Model Subscriptions Are Coming, But Who’s Buying?

We’ve all been there before — you need some 3D printable design that you figure must be common enough that somebody has already designed it, so you point your browser to Thingiverse or Printables, and in a few minutes you’ve got STL in hand and are ready to slice and print. If the design worked for you, perhaps you’ll go back and post an image of your print and leave a word of thanks to the designer.

Afterwards, you’ll probably never give that person a second thought for the rest of your life. Within a day or two, there’s a good chance you won’t even remember their username. It’s why most of the model sharing sites will present you with a list of your recently downloaded models when you want to upload a picture of your print, otherwise there’s a good chance you wouldn’t be able to find the thing.

Now if you really liked the model, you might go as far as following the designer. But even then, there would likely be some extenuating circumstances. After all, even the most expertly designed widget is still just a widget, and the chances of that person creating another one that you’d also happen to need seems exceedingly slim. Most of the interactions on these model sharing sites are like two ships passing in the night; it so happened that you and the creator had similar enough needs that you could both use the same printable object, but there’s no telling if you’ll ever cross paths with them again.

Which is why the recent announcements, dropped just hours from each other, that both Thangs and Printables would be rolling out paid subscription services seems so odd. Both sites claim that not only is there a demand for a service that would allow users to pay designers monthly for their designs, but that existing services such as Patreon are unable to meet the unique challenges involved.

Both sites say they have the solution, and can help creators turn their passion for 3D design into a regular revenue stream — as long as they get their piece of the action, that is.

Linux Fu: Making Progress

The computer world looks different from behind a TeleType or other hardcopy terminal. Things that tend to annoy people about Unix or Linux these days were perfectly great when you were printing everything the computer said to you. Consider the brevity of most basic commands. When you copy a file, for example, it doesn’t really tell you much other than it returns you to the prompt when it is done. If you are on a modern computer working with normal-sized files locally, not a big deal. But if you are over a slow network or with huge files, it would be nice to have a progress bar. Sure, you could write your own version of copy, but wouldn’t it be nice to have some more generic options?

One Way

The pv program can do some of the things you want. It monitors data through a pipe or, at least through its standard output. Think of it as cat with a meter. Suppose you want to write a diskimage to /dev/sdz:

cat diskz.img >/dev/sdz

But you could also do:

pv diskz.img >/dev/sdz

By default, pv will show a progress bar, an elapsed time, an estimated end time, a rate, and a total number of bytes. You can turn any of that off or add things using command line options. You can also specify things like the size of the terminal if it should count lines instead of bytes, and, in the case where the program doesn’t know what it is reading, the expected size of the transfer.

The Art And Science Of Making Beautiful Transparent Ice

For most of us, ice isn’t something we’ve thought about in detail since our high school science classes. For most of us, we pour some tap water into the ice trays, slam it in the freezer, and forget about it. Then we lob the frozen misshapen cubes into a beer and enjoy a quite literally ice-cold beverage.

However, there’s so much more fun to be had with ice if you really get into it. If you’ve ever wondered how pretentious cocktail bars make their fancy ice spheres or transparent cubes, read on!

Supercon 2022: Nick Poole Makes A Jolly Wrencher Tube

[Nick Poole] shared his circuitous journey into the obscure world of homemade vacuum tubes on the Supercon 2022 stage. It began innocently enough when he saw [Usagi Electric]’s single bit computer vacuum tube computer, which uses dozens of vacuum tubes. He got to wondering, could you make vacuum-tube-like devices containing multiple elements? There are some examples, like the 256-bit memory Selectron tube from the 1950’s, but nothing general purpose like a 555 timer or quad NAND gate packages. Unencumbered by a deep understanding of how vacuum tubes work, [Nick] proceeds to fill this void by imagining Integrated Thermionic, a fictitious company that exists in an alternate history where transistors were not invented and the vacuum tube reigns supreme. He also showcases a variety of innovative products that Integrated Thermionics manufactured over the decades, including surface mount tubes.

Dear Ubuntu…

Dear Ubuntu,

I hope this letter finds you well. I want to start by saying that our time together has been one of creativity and entertainment, a time in which you gave me the tools to develop a new career, to run a small electronics business, make fun things, and to write several thousand articles for Hackaday and other publications, but for all that it’s sadly time for our ways to part. The magic that once brought us together has faded, and what remains is in danger of becoming a frustration.

In our early days as an item you gave me for the first time a Linux distro that was complete, fast, and easy to use without spending too much time at the CLI or editing config files to make things happen; you gave me a desktop that was smooth and uncluttered, and you freed me from all those little utilities that were required to make Windows usable. You replaced the other distros I’d been using, you dual-booted with my Windows machines, and pretty soon you supplanted the Microsoft operating system entirely.

Ubuntu and me and a trusty Dell laptop, Oxford Hackspace, 2017.
Me and Ubuntu in 2017, good times.

We’ve been together for close to two decades now, and in that time we’ve looked each other in the eye across a variety of desktop and laptop computers. My trusty Dell Inspiron 640 ran you for over a decade through several RAM, HDD, and SSD upgrades, and provided Hackaday readers with the first few years of my writing. Even the Unity desktop couldn’t break our relationship, those Linux Mint people weren’t going to tear us asunder! You captured my text, edited my videos and images, created my PCBs and CAD projects, and did countless more computing tasks. Together we made a lot of people happy, and for that I will always be grateful. Continue reading “Dear Ubuntu…”
