How can this be transformed into an hilarious analogy for software development? As English is not my native language, I struggle to come up with something worth the faintest glimmer of a smile - but I suspect that it is something the regulars can easily come up with $Shucks | :-\$

The fact that it takes one woman 9 months to make a baby doesn't mean that 9 women can make a baby in 1 month.

I suppose it's more like trying to complete a paint-by-numbers project quicker by having multiple people each applying a different color.

Or building a house quicker by having all the tradesmen working at once.

Adafruit again

Now my Adafruit RA8875 breakout is causing a brownout detector trigger on my ESP32 - so it reboots an extra time every time it is reset. And my Adafruit SD breakout is dead unless you touch it just right (on the board - the headers have been soldered twice to make sure).

I can't replace the RA8875 with anything but another Adafruit but I found 5 SD breakout modules for half the price of one Adafruit module and from Hiletgo - a chinese brand I actually trust.

Why do I have such bad luck with Adafruit hardware, and only their hardware?

I want the parts in what I'm building to be sourced from my country if possible but when the parts I can get are much more expensive and I have to replace them with chinese parts that don't break what am I supposed to do? I could live with the extra cost, but the breakage I simply can't.

It's possible I'm just having *really* terrible luck right now, but only with them. It's possible. My cohort in this isn't having these issues. Our wiring is identical, we keep it synced.

I just don't know what to do. I can't keep using adafruit because money aside, i can't keep waiting by the mail and having project delays for want of parts.

I almost never have this problem with software because I rarely outsource

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

raddevus2-Dec-20 2:50

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:

I am not worried that they will settle it all... (it is the most logical step)
