You are hero! I just learned about this yesterday when I shared my Clojure editor: https://github.com/tlehman/hammock

I would love to know more about Jank, from what I read, it transpiles to C++ right?

Re:Ask HN: What Are You Working On? (April 2026) on Monday April 13, 2026 @12:40AM (#47747676)
Working on an Emacs-like editor that uses Clojure instead of Emacs Lisp. It has a C kernel and then uses libsci (Small Clojure Interpreter, built with GraalVM, so it has no Java dependency at runtime).

I call it Hammock, in honor of Rich Hickey's "Hammock Driven Design" https://github.com/tlehman/hammock

This is a contrarian take: instead of open source models running on private infrastructure being the dominant mode of AI, they instead argue that the returns to scale from cacheing intermediate reasoning steps could provide enough of a performance advantage to centralized models.

Lee Smolin wrote a good book defending the idea that time is not emergent: https://www.amazon.com/Time-Reborn-Crisis-Physics-Universe/d...

He came up with a framework where time is real (assumed), and then the laws of physics evolve with time, and then goes on to develop an evolutionary theory of universes, where universes reproduce by producing black holes, which spawn baby universes, with slightly different laws of physics. He then predicts that it should tend to produce universes that are optimized to produce black holes.

It's still worthwhile to look at 10x and 100x concentrations since these things bioaccumulate. Whatever negative effects are happening at 1x should be studied as we crank that concentration up. Might be fine now, but in 100 years? We should probably have an idea how the harm/effects scale

It all makes sense. Google is playing the editor factions against each other so they won't contest the Chrome-based Electron editors that prop up their monopoly.
Re:Software component names should be whimsical and cryptic on Tuesday September 13, 2022 @03:14PM (#32828955)
The choice of using totally novel and cryptic names for everything was intentional. The project is ambitious, and aims to do a completely fresh stack, (OS, drivers, network stack, identity, filesystem, etc.). Given that level of ambition, the choice of names was done remind the user that this is not just Unix and TCP/IP re-written, this is a whole new alien OS, based on distinct ideas.

The fact that Arvo (the kernel) doesn't even have a distinction between RAM and disk, or between PCI input and network input, is a much bigger deal than remembering that "Arvo is the kernel".

OP is right that naming can give a false sense of familiarity, so inverting that for things like this makes sense. Create a false sense of un-familiarity, to keep the users paying attention while they learn what they are using. That's been my experience so far, a heightened sense of awareness while reading through the cryptic documentation.

All these measures of biological age might be useful, but the real test is just waiting and seeing how long people end up living.

Why does a free basic checking account mean some some depositors are being subsidized? Is it the interest? The cost of storing an extra record in a database?

Multiple selections as a language primitive feels like a language smell. Why use languages with that much redundancy in their syntax?
Re:Money Creation: 344% in the Last 12mo (Fed, M1, $) on Wednesday February 24, 2021 @11:19AM (#26251604)
Definitely. The M2 supply grew by about $4T last year, from $15T to about $19T, it's a lot, but it's about one annual federal budget in normal years. $4T is like 20% of GDP, not nothing, but not hyper-inflationary.

The question is will M2 grow by 20% per year, or is this a one-off?

Post it's output to StackOverflow, then use the S.O. votes to tune the parameters of the model.
Re:Π-Base – A community database of topological examples on Tuesday September 15, 2015 @12:26PM (#10221527)
It looks similar to the OEIS (Online Encyclopedia of Integer Sequences). Any time a problem comes up whose solution involves topology, this is a good place to go and avoid re-discovering a space that might already be known and well studied.
I love PKD's work, but every time I hear him talk, I become convinced he is totally insane.
What about a P.O. Box and a TaskRabbit?
Re:Ask HN: Which book are you reading these days? on Thursday April 09, 2015 @01:24PM (#9349242)
I'm reading that one right now too, pretty intense, I usually make the assumption that people in other industries always have a level of expertise and proper practice that puts software to shame. However, hearing about the haphazard construction of early nuclear weapons and all the things that went wrong managing the Titan II complexes was really revealing.
