Inspired by this tweet:

Here's a list of choices ISPs and network operators made back in the '90s and early '00s with unintended consequences that damaged the Internet.

(Mea culpa: I'm one of those operators). 1) As e-mail became popular with residential users, spam delivery volume went through the roof. ISP operators decided best practice would be to filter port 25 (SMTP) so that residential users couldn't host email servers.

This broke so. many. things.

Decentralizing the Internet in a tweet:

Embed details for a fidelity bond and associated list of TLDs in nameserver's SOA record; client resolvers can compare age and amount locked in fidelity bond to decide which NS is authoritative for a given TLD

That's it, that's the tweet (Whether offering alernatives to the root nameserver is enough to count as 'decentralizing the Internet' is an open question, but it's at least a step in the right direction IMHO.)

Still digesting the #FinCENFiles dump, but going over it so far has helped crystallize something for me:

I don't think the dollar is going to be replaced anytime soon, but I don't have the same kind of confidence in the dollar *system*. I don't quite grok how dollars can continue to exist without the dollar system.

But I also don't get why Tether trades pari passu to the dollar (even after Bitfinex admitted it was less than 100% reserve backed!)

You plebs put Abqaiq dead last behind even Ukraine on this poll, so now you get a solid eight bagger on Things I Wish We'd Talk About When We Talk About Oil. #1: The total amount of oil production is by itself not a useful metric; more important is amount of oil produced per capita.

In 1980 during the glut, the U.S. had ~220 million people and produced ~9 million barrels a day; today it's ~13 million barrels for ~330 million people. Image

Tell me what you do at $DAYJOB writing software, and I'll tell you what food service industry job you'd be comfortable working at.

Thread! You work at a nameless Fortune 500 company, churning out updates to the internal homegrown CRM software. You desperately want to leave but you have student loans to pay and this was the first temp-to-hire gig you could find.

You're working at McDonalds, and you effing hate it.

It's days like this I wonder - is it time for the ground up beetles, or the wheat poultices?

(Thread on how George Washington died. Mostly.) On the evening of Dec 12, 1799, Washington came down with a nasty cough. It progressively worsened over the next 36 hours, until he woke up in the middle of the night on the 14th in severe respiratory distress.

Was it the State that vouched for the money, or was it money that vouched for the State? On the Lydians vs. the Abbasids: "...the sekka, the right of the ruler to have his name inscribed on coins, and the ḵoṭba, his right to have his name mentioned in the sermon at the congregational worship service on Friday, were the two formal prerogatives of sovereignty....."

"Layering has both technical and social implications: it makes the technical complexity of the system more manageable, and it allows the system to be designed and built in a decentralized way."

How layering made building the ARPANet possible: ImageImage "The ARPANET was born from an inspiration and a need..." Depending on who you ask, the ARPANet was built to enable time-sharing of remote compute resources, or a military command-and-control capability that could withstand nuclear attack, or - my fave - man-computer symbiosis.

You're all just toxic HTTP maximalists. Gopher is where the real innovation is at.

ils.unc.edu/callee/gopherp… Image "Broad social trends, roughly what an economist would call "network externalities," play a significant part in the adoption of one technology over another. I contend that ... the Web did not overshadow Gopher simply based on the technical qualities of HTTP as a protocol." Image

Problems in distributed systems that are suddenly much harder when you're building an exchange: a non-exhaustive list. (Thread). Logging is *hard*. Much harder than you'd think, because most of the time logging is actually easy.

An exchange that only logs every ask and bid and every order filled can couple their logging infrastructure with their COGS - you get paid for things that you log, so...

Start here and read backwards in this thread where @matt_odell anticipates the abuse of proof-of-stake by exchanges several quarters in advance Organizations in charge of maintaining custody for users that only want exposure to price are often big fans of a) forks b) airdrops and c) proof-of-stake - all are methods for gaining more coins just by holding keys to existing coins

I'm still mulling over yesterday's one-two punch of Venezuela's devaluation and Iran's Central Bank switching to yuan from USD on it's rate reporting platform.

This AM I re-read this paper from June, about future of the international monetary system, with fresh eyes. (Thread) High level summary: the authors posit that there are four potential paths the IMS can take, depending on a) whether a systemic crisis serves as a catalyst for change or not (revolutionary vs. evolutionary) and b) whether nation-states will cooperate or compete in either scenario.

Hey flood of new followers! Seems only fair to warn you about what you're getting into. Here's the sort of stuff I tweet about... at *great* length, apparently.

A tweetstorm about tweetstorms - if this doesn't get you to unfollow me, idk what will. Thread! Why the Bitcoin scaling wars felt familiar to me:

A thread on the Shanghai INE crude oil futures, what they represent, what everyone is missing, and why I think they're worth paying attention to.

Let's do this. (Thread 2 of 2!) The futures contract is not the petroyuan; rather, a functioning futures market for oil priced in yuan is a necessity for any oil producers
to consider delivery in yuan.

A thread on the Shanghai INE crude oil futures, what they represent, what everyone is missing, and why I think they're worth paying attention to.

Let's do this. (Thread 1 of 2!) First, some background: in late 2013 Xi Jiping announced the 'One Belt, One Road' initiative, which might best be described as a Chinese Marshall Plan. By May 2017, the OBOR began to transition from vague dream to tangible reality. A quick explainer:

I mentioned this quote in a tweet earlier this week; it's from a hysterical, irreverent rant - well, series of rants - by a protocol engineer in the 80s by the name of Michael Padlipsky, in a book titled 'Elements Of Networking Style'. (Thread 1/10) Padlipsky spent almost a decade of his life politely - and sometime less politely - telling anyone who would listen that ISO was garbage and TCP was here to stay.

In today's jargon: he was a TCP maximalist. 2/10

Behold: a 20-bagger tweetstorm that will alienate most of the people that follow me.

I present to you a short story on 'The Glenmutchkin Railway', written in 1845, as a warning to future participants in The Great ICO Mania. (Maybe). 1/20 "These were the first glorious days of general speculation...." The start of the railroad bubble makes the dotcom mania look tame. 2/20
