What is 'Bikeshedding'?
"Bikeshedding," also known as Parkinson's Law of Triviality, is a phenomenon where people in an organization give disproportionate weight to trivial issues. It's often seen in meetings where complex topics are glossed over, while simple, easy-to-understand (and thus seemingly easy to contribute to) issues consume an inordinate amount of time and debate.
The term comes from C. Northcote Parkinson's book "Parkinson's Law," where he describes a fictional committee tasked with approving plans for a nuclear power plant. They breeze through the complex details of the reactor itself (because they don't understand it), but spend hours debating the trivial design of the bicycle shed. Everyone can visualize a bicycle shed and has an opinion, so everyone wants to contribute.

translations were done by an AI agent.
this used to be one of the worst software development experiences *EVER*: replace every string in your application with a translation placeholder varaible and move all into a localization file and translate.

This is for the devs. It's ok when people complain. When your project catches on and reaches a certain level of use, you will be faced with an infinite stream of complainers. There's no way around it. There is an infinite supply of negative people who don't build things but just type comments. You must understand that their opinion does not matter to you. Otherwise you will be crushed by the negativity that will surround you 24/7.
You have one job: find those complaints that have actual merit. They are very rare, and most of the time they do not emerge from an angry person but a calm one. Filter information that you can make use of and ignore the rest.
What I can tell you with 100% certainty is that the complainers don't matter. They do not determine your success or your failure. They are not your target users. Compared to them they are a tiny minority. You aim for the rest. As long as you stay truthful to yourself and to your users, and as long as your product is useful to them, you will grow.
Note: this post makes it sound like that there is only negativity out there which is absolutely not the case. The vast majority of interactions you will have our positive and encouraging. Also, go to conferences. All the tough guys online are sweet like puppies when you meet them face-to-face.

Yes! We're also thinking about giving every community their own mint. Cashu zaps are verifiable by checking the p2pk lock against receiver pubkeys + dleq proofs against mint pubkeys.
You could do this with a "pure" Lightning wallet even that generates nuts only at time of zapping.

the nostr wallet experience is pure magic. if you know what's happening in the background it kind of breaks your brain. if you have no idea, it just works.
ecash zaps are instant. they always succeed. the wallet is hyper portable. log in to a completely different nostr client and your money appears.
ecash + nostr is going to set the bar for what payments on the web can be https://nostr.download/fcdc410e99b3d294f93bde3071a5206ffc89690b4d456b2548e73cde547de82a.mp4

"We are a hardened bunch, cypherpunks who have seen the life cycle of Bitcoin play out with its positive and negative developments, and therefore, we are wise to the pitfalls that lie ahead. Because just like how the smallest government inevitably becomes the largest, so too did Bitcoin become corrupted by the system it was meant to replace. But what cannot be replaced is our relentless idealism, that ardent crypto-anarchism which pushes back against a looming cyber dystopia."

Major software companies are massively reducing their staff because their devs become vastly more productive due to AI.
The difference in productivity between devs who master AI and those who reject it is growing at an incredible pace. And it's going to accelerate.

🔥 Nutshell 0.17.0 released – Blind Authentication, Multinut Payments, Wallet Improvements, and much more!
# Improved Multinut Payments
Please upgrade your mint! It's important that we can improve the multi-nut mint network – if you want to support it, use LND or CLN as your backend. Once a few mints have upgrade, we're going to roll out wallet updates that can make use of this.
It's going to be so insane, I promise. I've been paying things with it for a while.
## Blind Authentication
You don't need to run a mint for the entire world anymore. Nutshell now integrates with an OAuth 2.0 identity service of your choice. You can run your own (Keycloak docker included) or use another service. Ideal for mints that should serve specific communities. Wallet updates are pending, we're going to roll this out bit by bit.
