Built an enclosure for an Antminer S9, to manage sound and heat.

- Duct quick-connects for easily swapping intake/exhaust
- Finished w/speaker carpet over 1/4” padding for appearance and sound reduction
- Sound reduction from muffler on exhaust, baffle+underhood material on intake side
- Power & Ethernet extensions, will primarily control remotely

Tinkercad model:

Made a few tiny adjustments to account for
cut width, should be easy to figure out.

Bitcoin Optech newsletter #202 is here:

- describes experimentation by developers working on silent payments
- HWI 2.1.1 and LND 0.15.0-beta.rc3 releases

Meanwhile, took the opportunity to install LIT on my raspiblitz. Web-based GUI looks pretty slick. I think I will try out the new Lightning Pool feature, even though I have special need for more inbound liquidity, I'm really curious to see what it's like making a bid and getting it filled:

Have run these ⚡️ benchmarks on a 64bit RaspberryPi4 with a USB SSD and got relieved that this common setup is not a bottleneck for the Lightning Network.

We've been digging a little deeper into Lightning node performance 🤓

Here's what we've fou…

Peer-To-Peer Is Patriotic.

"Peers freely electing to interact with each other could be used to describe citizens constituting a constitutional republic such as the United States of America or nodes in the nebulous network of Bitcoin."

Worth a read; h/t @belcher

this is an oft-discussed scenario, I tend to think it will be a less significant effect than portrayed in this article; I am probably influenced by the history of bitcoin; I haven't seen evidence that prices are ever lower outside centralized exchanges (the opposite?), seems mostly surmise, not data.

The author may be under-stating the importance of the perfect verifiability (and doesn't understand intrinsic fungibility).


Learned of this via TFTC h/t @mattodell ;

there's a short video demo and a slide deck, basically this is a mobile-to-mobile BIP78 payment implementation (interestingly, seems to be iPhone) using onion service for receiver as Joinmarket does. Was part of an MIT hackathon.

Most interesting if this BIP78 implementation makes its way into production mobile wallets, will be a great selling point ...

My GUIX #Bitcoin bootstrapped deterministic build worked. After 4 days compiling through sources it was done.

Listening to bitcoin newbies asking their questions on CH, I get the impression that they think we never made mistakes along the way.

You basically have to make mistakes while you learn how to Bitcoin.

Embrace it and start the process. Learn by doing.

You don't have to go newcoiner zero to full bitcoiner hero all in one go.

You're allowed to take small baby steps and learn along the way.

e.g. if your coins are on exchange and you're scared about self custody, try a small amount on a phone wallet to get comfortable.

Dollar Cost Average into Bitcoin

This started as an idea for a weekly microblog series and scope crept into a side project. Recently I’ve had more casual observers asking me how to buy BTC. I turned my notes into this small Hugo site. Rates will be updated every Saturday.

Sharing with the fediverse first, please provide feedback!

The Nevada Innovation Zones proposal seems highly targeted at Blockchains LLC “Ethereum City” project, whose weird ads were plastered everywhere in Prague during the Devcon IV conf

Haven’t heard about it since, but they must be going forward with the idea

Decoding The “Bitcoin Full Node Sculpture,” A Cypherpunk Chronometer.

"The Bitcoin Full Node Sculpture is a cypherpunk chronometer, designed to work as a fully-functioning bitcoin full node and block explorer."

If you’re a developer in 2021 and you’re adding tracking devices from Google, Facebook, etc., to your sites and apps, the one thing you can’t do any longer is to feign innocence. You know exactly what you’re doing and you’re complicit in perpetuating surveillance capitalism.

Bold stance:

If you're running a successful business that's built on top of open-source software and you're neither contributing code to these projects nor donating money to them, you're not only a freeloader, you're actually harmful to the entire movement.

You should take an interest in the sustainability of these projects as they ensure the likelihood of your own success and future.

Every bitcoiner should familiarize themselves with jq. Such a handy tool for so many situations. (considering the ubiquity of json)
