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…

Similar situation here. I usually can hack something together in python, but end up spending a couple hours reading stack overflow posts, and often meeting with co-workers to debug my code. Chat-GPT can often write simple code for me and honestly saves some time.

Because as an industry, we are bad at our jobs. The network facing software has critical security vulnerabilities. Even security folks accept that as the way of the world. At the point the software is released it has (hopefully) no known security vulnerabilities, which is a reasonably secure situation to be in. However, eventually some of them will become known, and that is not safe.

But a "critical security vulnerability " depends on the use. My daily driver? Yes, I want all of the security updates. A raspberry pi for playing arcade games that I occasionally scp a ROM over to? I really don't care if someone hacks in. We, as an industry, are bad about pushing "every device that is on the internet needs to be as up to date as possible all the time" when it reality there is a lot of unimportant stu…

Well, a common thing with open computing resources these days is cryptominers. Sure, you don't care about updates, until someone puts a miner on it and you have to go in and try to fix it. It wouldn't matter that your single device doesn't have enough processing power when there are tens of thousands of similarly vulnerable devices to hijack.

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 can find used iOS devices that run iOS 15, and therefore modern safari, for like $80.

Agree with this. You want something with the least headaches as possible. You should be able to run the the Home Assistant App as well.

If you get a old iPhone and buy a replacement battery still more than likely be cheaper than buying a Rpi + screen + lipo-hat + battery.

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…

If you want to play with it for a while then put it away forever, go ahead and do it; but if you want to build something long-term, better find a different board.

I think it depends on what you want to do with it.

If you're building something that won't access the network, or will be isolated to the LAN, then it's fine.

Not everything needs or wants to be connected to the internet.

Why would a connection to internet need security updates?

Because as an industry, we are bad at our jobs. The network facing software has critical security vulnerabilities. Even security folks accept that as the way of the world.

People like to shout "cryptobotnet!" every time someone questions the need for absolute security with devices connected to the internet.

You might get 2¢ in about 40 years mining with my IoT light bulb. Good luck with that.

As usual, looks good on papier but no ecosystem and the current stack that it comes with is dead on arrival. Boards need to come with mainstream distro support or with an ecosystem (or both), otherwise it will just die. And with internet connected devices, you can't set-and-forget, so it needs to have live support. Edit: a RockPi S (same SoC) can be had for $35 and a touch LCD for $11... Granted, it doesn't come with…

I purchased a few ARM boards in the past and won't do it again. All became e-waste.

Rockchip notably, great hardware on paper. Try developing something that needs hardware acceleration and it's a paper weight.

It's a common cycle of broken promises to provide drivers by manufactures, rinse and repeat. The exception being raspberry pi or expressif. Depending on the application.

There are plenty of reasons not to want your IOT bulb to be insecure that are unrelated to people mining crypto.

A pwned IOT lightbulb can be used to help DDOS sites. It can relay DDOS traffic, eating your own bandwidth. It can be constantly probing the other devices on your network looking for vulnerabilities, until it pwns something else and is able to slurp down your passwords and credit card numbers.

Are you seriously suggesting that having an actively malicious computing device inside your home network is no big deal?
