Adlai··on Ask HN: Physics/engineering lessons for 14 year olds?
I was slightly younger than fourteen when my fifth-grade teacher staged a bridge-building competition in the class. She priced the raw materials (mainly toothpicks, glue, and string; I can't recall what the various exotic items were), and graded us based on ineffables such as teamwork and empirical metrics such as how much we spent on materials and how much weight the completed bridge supported.
Adlai··on Why I Don't Love Gödel, Escher, Bach (2018)
As is often the case, this review can be recommended instead of the book; anyone who still wants to read the book after the review, is quite likely to enjoy it.
Adlai··on The resolution of the Bitcoin experiment
You can restrict the supply within a single system, and value follows the network effect due to fear and greed.

https://coinmarketcap.com/ lists 650 alternate value storages which take up 650 million dollars. Bitcoin alone takes six billion.

Adlai··on Doomsday planning for less crazy folk
No mention of Bitcoin?

Oh right, the experiment failed.

Too bad, too bad.

You just made me laugh out loud :)
Adlai··on Introducing the Shift Card: Use Bitcoin where Visa is accepted
Stellar has a consensus protocol?

Last I checked, there's a single blessed node dishing out verifiable data. It's nicer than having a remote API that just hands you a trusted number, but it's a far cry from Nakamoto Consensus.

Adlai··on Introducing the Shift Card: Use Bitcoin where Visa is accepted
Bitcoin transactions are much harder to censor than conventional fiat transfers, but the transaction graph is completely transparent.

[1] - It occurred to me that I selected predominantly positive, or at least 'wonderous', reports. Dig around and you'll find some that are less so.
Adlai··on Getting rid of free office snacks doesn't come cheap
Seems like a good opportunity for a company that genuinely cares about employee health to make it easier for them to eat well by stocking the kitchen with healthy snacks.
Adlai··on Ask HN: How could we solve the problem of domain squatters?

  People asking questions, lost in confusion
  Well, I tell them there's no problem, only solutions
    - John Lennon
The other solutions proposed here work at the wrong level. The approach taken by I2P[1] does away with the concept of globally squattable names[2], leaving public keys as the global identifiers and letting individuals define local nicknames or delegate to trusted lists.

[2] Even http://www.aaronsw.com/weblog/squarezooko is susceptible to squatting by those who can invest (or rent) computing power.

PS: I had a chance recently to talk with a "DNSquatter": the doorman at a building I frequent. Poor guy bought tens of thousands of domain names, years ago, with money he had available for investment, and asked me for advice on how to cash out his investment. It seems to me that he's the victim of a chumpatron[3], rather than the scammer himself; although his actions do help keep the scam alive. I advised him to consider the money lost.

Adlai··on MMM Ponzi scam may be main reason behind Bitcoin price fluctuations
Such scams only raise the price if the fools hold Bitcoin instead of what they most likely do: sell it for local currency. The scam's popularity does boost transaction volume, critical to the emergence of a fee market.
Adlai··on The Uberization of Money
Yet another article about the somethingization of money that doesn't mention decentralized currency, or even plain old digital. I get that people love hating Bitcoin, but isn't it fashionable at the very least to nod at the underlying technology?
Adlai··on The Trillion-Dollar Vision of Dee Hock, the Radical Who Organized Visa (2012)
Today, Hock is on the advisory board of Xapo, claiming that "Bitcoin is one of the best examples of how a decentralized, peer-to-peer organization can solve problems that these dated organizations cannot." How about that pivot!

Adlai··on The primacy of the US dollar looks unsustainable
Your government shouldn't care what form of money you're using, as long as it gets its fair taxes.
Adlai··on Children of the Yuan Percent: Everyone Hates China's Rich Kids
Vonnegut disagrees in Player Piano. It's an interesting read for programmers, since he got the details of automation wildly wrong, but "the story is true".
Adlai··on 'Dissent,' a New Type of Security Tool, Could Improve Online Anonymity
Satoshi published a PGP key, but never signed any of his public communication. Reading the recent email[1] sent under his name suggests why:

Bitcoin was designed to be protected from the influence of charismatic leaders, even if their name is Gavin Andresen, Barack Obama, or Satoshi Nakamoto.

Adlai··on The Decentralist Perspective, or Why Bitcoin Might Need Small Blocks
My favorite perspective on this Tragedy analogizes the Commons in question to a cavern whose acoustics preserve any sound shouted within. We could allow more people to shout at once, but that would increase the number of echos, increasing the total amount of "signal" and effectively decreasing the SNR when all you're interested in is a single signal out of the whole cacophony. As the permitted transmission bandwidth rises, the complexity of making sense out of the received data increases at some sharper rate that I won't just pull from my ass.

The fundamental right that must be preserved - the action that must be kept accessible at minimum price to anybody wishing to perform it - is not that of adding data, but rather verifying and interpreting that which is already present. Shouting should be expensive, because you hurt every other eardrum.

Forth is as high-level as you'd like it to be.

Adlai··on Lisp is still a secret weapon
Please avoid referring to the language as "CLisp". It's Common Lisp or just CL, of which GNU CLISP[1] is but a single implementation.

You missed the recursion:

Hofstadter's Law: It always takes longer than you expect, even when you take into account Hofstadter's Law.

Adlai··on Intellectual pursuits may buffer the brain against addiction
I'm also reminded of an interview with an actor who said that cocaine didn't add much to his life, since he'd get the same rush from walking onstage each night, without having to spend $100 before or suffer a crash after.
Adlai··on Is Advertising Morally Justifiable? The Importance of Protecting Our Attention
I actually look forwards to the ads before movies on the rare occasions that I do attend cinema screenings. Since I watch no TV (and grew up without one) and make a point of minimizing my exposure to online advertising, this serves as an amusing little peek into the current state of pop propaganda.
Adlai··on Is Advertising Morally Justifiable? The Importance of Protecting Our Attention
Wouldn't the individuals behind organizations such as the EFF and ACLU gladly stand behind their message?

Adlai··on Many Bitcoin wallets vulnerable to double-spending of confirmed transactions
There are coinbase flags for neither SPV status, nor honesty.
Adlai··on Many Bitcoin wallets vulnerable to double-spending of confirmed transactions
It's sensationalist to suggest this vulnerability is anything new. The warning is late, indeed... I'd suggest putting it in the Terms of Service of every SPV wallet, but then even fewer people would read it. Maybe a better approach would be a popup each time the wallet blindly trusts a new merkle root?
Adlai··on Many Bitcoin wallets vulnerable to double-spending of confirmed transactions
For the sake of quoting Greg Maxwell, I'd like to pick a nit. Bitcoin has no rules other than those you enforce yourself, and all these pools did was enforce fewer rules of their fellow players, than we assume they do.[4]

Optimize would be less judgmental than cheat and speaks more precisely to the motivations[1]... we do need to be careful about this and make sure we're managing the incentives. Cheating is a moral judgement[2]

Bonus quote, unearthed while digging up the above:

While the identifiable parties in question here were Chinese; the first miners I saw doing this in the pastwere not Chinese-- it's not a Chinese specific issue; its a response to orphan rate. (China just has lots of hash power and poor connectivity).[3]

Adlai··on Many Bitcoin wallets vulnerable to double-spending of confirmed transactions
The title is a little sensationalist. While the majority of wallets do only have SPV security, and such wallets were vulnerable to double spending during the recent fork event. The fork is over, so the wallets are no more vulnerable now than they were before (this vulnerability is not new).

I hope this incident has convinced other miners that the ~1% profit boost from "SPV Mining" is not worth the fork risk that it enables, although apparently one of the pools (Discus Fish aka F2Pool) has already been warned against SPV Mining in the past. Let's hope that coins lost through this fork event is the sterner warning they needed.

Adlai··on Many Bitcoin wallets vulnerable to double-spending of confirmed transactions
Two mining pools (Discus Fish and Antpool) were engaged in what's called "SPV Mining", where they assume a block broadcast by another miner is valid based solely upon the block header (essentially, just checking that the block was "difficult enough"), without verifying (or downloading!) the transactions in that block. This strategy lowers their orphan rate at the cost of the risk that they'd waste work by mining on an invalid chain. This low risk was increased by the BIP66 enforcement (activation happened once only 75% of the blocks had the version 3 "flag").
Adlai··on Write code every day
"Hey hey hey..." yep, that one doesn't quite work either.
