This device is similar to many hacker festival badges from the recent years. Just a bit more expensive. For example: - the Camp 2023 flow3r badge https://events.ccc.de/2023/06/05/camp23-the-flow3r-badge/ - the MCH2022 badge https://wiki.mch2022.org/Badge - the SHA2017 badge with E-Ink https://wiki.sha2017.org/w/Projects:Badge - the Camp 2011 badge R0ket https://events.ccc.de/camp/2011/wiki/R0ket The first three have…

The “documentation” page is a joke. I cannot eve find if the touch screen is resistive or capacitive. I see no schematics, making bring up if your own OS in it unlikely. I see no data sheets either. Just another piece of e-trash waiting to end up on a landfill..

My usual question for small cheap boards is: what will happen to OS support in 3 years? Is it using regular distro or is this a custom fork which will likely be never updated? The website says: > The UNIHIKER comes with a Linux operating system based on Debian and various built-in features, which will be upgraded from time to time. ... don't expect OS upgrades here. If you want to play with it for a while then put it…

Why does it need continuous, perpetual support? Most devices like this get built, software installed, and never updated again. When is the last time you updated the ECU software in your car? I built a small arcade cabinet using an old raspberry pi 2b. Once I built it I've never needed to upgrade anything on it. It works fine and plays all the old games. I have backups of the SD card in case anything craps out.

> Why does it need continuous, perpetual support?

Because there are no schematics or data sheets posted on that page. Good luck bring up anything else on it…

This definitely puts the STM32F429 Discovery board to shame with its now inflated $80 price tag.

That dev board has a schematic and data sheets for all parts. This one has a flashy website with no such thing. That’s what you pay your $80 for

Earlier quoted context omitted.

I'm incredibly curious what the experience of trying to write code with ChatGPT is like, if you have no prior knowledge. Obviously, it's impossible for me (and most others reading this) to un-know everything and approach it with fresh eyes. Are there any good real-time videos of non-programmers using ChatGPT to write code? (seems like the best way to understand what it's like)

I am an engineer, but not a software engineer. I write python sometimes to help me do engineer-y things in my domain but I am absolutely not very fluent, just enough to get by. chatGPT often transforms a frustrating multi-hour stack overflow session into a 5 minute query. The result is definitely not something you'd want to maintain and probably has built in inefficiencies and edge cases I don't know about but it did…

Honestly for tasks it’s able to do easily ChatGPT code is probably more maintainable because it’s more well-commented, formatted etc. than code a human would write if they’re just trying to quickly hack something together

Sometimes I think “you can tell this part of my code was generated by ChatGPT because it’s actually good, unlike the rest of it”

Of course it’s likely to make subtle mistakes that are hard to debug if you ask it to do anything complicated because it can’t test its own code (well, I’ve heard something about a code interpreter in the Plus version but I don’t know how well that works)

I'm pretty sure that was a game/gimmick and part of the conference badge challenge. But maybe not. Regardless it is a security conference after all and I'd totally expect people to be playing around like that. I don't think it would have been seen as malicious.

Unrelated but trying the HN wisdom here: any suggestion for a cheap touchscreen with a CPU attached and a battery that can be used as a control panel for Home Assistant? Yeah, probably some Android tablet but something that actually works well for this job and costs as less as possible? I cannot power it properly where I want to put it so it needs battery and then I can charge it as needed. Suggestions?

You'd be able to strap something together with a Pimoroni Hyperpixel and a raspberry pi with a lipo hat, if that was a direction you wanted to go in. It's a very nice little screen. No idea about how power efficient it is, though.
