Here are some dorky stickers I've made.

These designs are available for public use. You can use them on stickers or shirts or whatever. I'll drop the full images and their license info in the comments below.

"Move Purposefully and Fix Things" (Public Domain Work)

A twist on Facebook's "Move Fast and Break Things" motto. I designed this in 2018 after reading a presentation from DJ Patil about a code of ethics for data scientists https://www.oreilly.com/radar/doing-good-data-science/

Doing good data science

Data scientists, data engineers, AI and ML developers, and other data professionals need to live ethical values, not just talk about them.

"There is no use for the blockchain that can't be solved cheaper, better, and more reliably with existing tech." (Public Domain Work)

After running an anti-NFT twitter account called NFTThefts, I found myself repeating some variation of this phrase in my replies to crypto-supporters. I made this design so I didn't need to keep typing the same thing over and over.

"Never Mind The Cryptobros. NFTs suck. The blockchain is bollocks" (CC-NC)

After designing the "There is no use for the blockchain" sticker, I thought I'd take a stab at designing something a little more eye-catching. A Sex Pistols parody seemed appropriate.

Sidenote; Johnny Rotten tried selling NFTs during the fad. Of the 100 listed, only a handful have actually sold.

@docpop it’s true. Blockchain is horribly computationally wasteful. And uses so much electricity. Such a waste. And we have an environmental crisis. And yet we spend millions of tons of CO2 on… blockchain. #blockchain #bitcoin #environment #co2
@jsecure @docpop yeah but how about that giant network of ATM machines and physical bank branches? comparatively a much bigger waste of resources in my humble opinion.
@perlman @docpop no chance :) All the ATMs in the world pale in comparison to the sheer energy needed to crunch the numbers for blockchain. Blockchain uses as much energy as an entire nation.

@docpop

My beef is first with cryptocurrency, needing "mining".

Any system that requires traceback to the origin for final verification is not sustainable.

Neither is any cryptocurrency needing the power equivalent of Finland.

@docpop
I read about one exception: Walmart Canada contracts their transportation with all sorts of trucking companies and other transportation contractors. They do lots of business with some, very little with others. They use some kind of blockchain thing as a decentralized database for their transportation contracting, to do stuff like bid for transportation, track payments, and so forth.

Digression: apologies for finding something good to write about Walmart.

@docpop
It _could_ be done with a conventional database, but that would necessitate authentication to the database, which they apparently found more problematic than their blockchain database.

They pay contractors with real money.

Given the narrow domain, it probably doesn't have the ridiculous energy cost of cryptocurrency "mining".

Cryptocurrency and NFTs are two kinds of scams for different types of suckers, but that seems like a legitimate exception to the blockchain's uselessness.

One additional value for blockchain: if you're a mail-order heroin dealer, and keep your business volume small enough that law enforcement isn't going to bother with the digital forensics to find you, cryptocurrency is a great way to do business. Your transactions are pretty well hidden in the clutter of transactions by speculators and Ponzi scammers.

Works for any contraband. Just don't get big enough to get noticed.

@Steve98052 I reached out to Walmart CA a few months ago about this. They confirmed they were using the blockchain, but only because that's what their vendor (DLT Labs) had chosen. So far, it doesn't seem to solve any problems that couldn't be solved without the blockchain and it doesn't appear that any other Walmart chains are planning on switching to it. In fact, most of the DLT Labs blockchain-inventory-management competitors have given up on their projects: https://newsroom.ibm.com/2018-08-09-Maersk-and-IBM-Introduce-TradeLens-Blockchain-Shipping-Solution

@docpop
Good to know. I read a glowing report about it in a reputable academic publication, but maybe it was just one of those things that slips through peer review without enough challenge.

My father once got fed up with buzzwords in a particular academic journal, and submitted an article, loaded with fashionable buzzwords, that said nothing at all, timed to appear in the journal's April issue. On strength of his record, they half-assed the peer review.

@docpop
As soon as he got the print issue with the prank article (not sure whether it landed in the April issue), he wrote them a letter saying, more or less, "April Fool's!" The journal was not pleased.

It wasn't quite thiotimoline, but it was a real journal.

@docpop nice hypothesis but really isn't playing out like that. I'm not a fan of NFTs in 99.99% of projects and tend to blinker myself from seeing where they're touted, but I like Bitcoin a lot and global finance is due a reform.
