Hmmm... I have had great luck with
ELEGOO UNO R3 2.8 Inches TFT Touch Screen with SD Card Socket[^]
And the entire thing is only $15 USD.

I've built quite a few things with them. However, what I've really found are the challenges of insuring that
1) data lines are not getting noise on them
2) data lines are solder perfectly

If your data lines are just slightly "loose" you will find that you will get all kinds of troubles that are not re-producible.

Check out my article here at cp[^] to see the touch screen in action.

Thanks though client requirements dictate our 5" model 800x480. The whole reason we moved to this setup from the ili9341 is the requirements for more pixels and more physical surface so we're locked in, save for a 5" color alternative with similar specs

Never heard of them - thanks for the lead! I'll probably order something from them and never implement anything, just as I did with the Rabbit 2000 and Omega2 development kits. Still, it's fun...

Blockchain beliefs

I'm reading this book, Building Blockchain Apps (Addison-Wesley Professional)[^] and I came across the following which explains Smart Contracts:

Quote:
In Code We Trust
The smart contracts can often closely resemble legal contracts in the real world. For example, the transaction parties might enter an escrow agreement that the fund will be paid out only when certain conditions are met.

It is now up to network validators and maintainers to assert whether such conditions are met and how the transaction should be executed when new blocks are appended to the blockchain.

However, unlike legal contracts that are enforced by the centralized government power, the smart contracts can automatically apply collaboration rules on the blockchain. The rules are written in code and checked by trustless participants of the network to prevent corruption or collusion.

Because of that, we consider smart contract code the “law” in blockchain networks. The code is executed as written. Even if the code contains bugs or side effects unexpected by its author, it is still trusted as a source of truth and enforced as the law.

So smart contracts are going to enforce rules for transactions which become "law" (the system will not break the "law" (code), no matter how fouled up the "law" may be").
Do these Blockchain enthusiasts not understand how buggy software is? Roll eyes | :rolleyes:

Oh, no worries, when this all lands our AI Overlords will settle it all. Laugh | :laugh:

I am not worried that they will settle it all... (it is the most logical step)
I am worried that they will get to the position to settle it all... Unsure | :~

True, but computers only do what they are told to do. They never, ever break the law. They can't. They can't think or decide. They simply execute code and do exactly what they are told to do. Even when there is a "bug" the computer did exactly what it was told to do.

I didn't say correctly. But the computer only did what it was told to. A computer can't do anything but what it is told to do. It's impossible.

I know what you mean, but this isn't as true as you would like to believe any more.

To discuss it further you would have to read the entire book, The Creativity Code by (mathematician and professor) Marcus du Sautoy[^]

That sounds a bit arrogant, but it's not intended to be. That book explains that there are now algorithms that are continually updated by AI which make decisions which humans no longer have a way to track.

The really interesting example is where the Go (ancient game) algorithm made a Go move while playing the best Go player in the world. The commentators noted that the move was not intelligent. But then that move caused the algorithm to beat the human player.
Now that move is a standard move at the stage of a game of Go but the move was "created" by an algorithm and no one can explain why the computer chose that particular move.

There are many other things where it is now becoming impossible to point to source code where the decision came from. quite interesting. Read the book and see if it starts to change your mind on these things. It's really fascinating.

Using your bank analogy, can you imagine a financial application that could not track down when and how money moved? Laugh | :laugh:

Yeah, they'll just tell the customer, "well the computer decided and we know computers do things correctly". Laugh | :laugh:
