For what it's worth, here's my take: turning off social media is far and away more "zen" than having it, no matter how infrequently you use it. Being unplugged from that culture has helped me spend more time thinking abo

What is the problem your friends have with you not being on Big Social Media? Is it that they want to be able to message you over those platforms? Or do they want you to see things they post? Or something else?

I've recently moved to this model too. I follow mailing lists and blog feeds via emacs gnus. I don't use fb or twitter bc I don't think the (content value)/(time) ratio is too low

I'm at the point in my emacs journey where I'm looking for places in my day-to-day editing that can be made more efficient by writing code that writes that code. I have implemented some helpful macros, but I think I would benefit

are your configs anywhere online? I'd love to read them.

I don't think any of the comments so far have addressed what EY is trying to get across with this story. He's saying we aren't very good at extracting information from data (doing science), but that we do have tools that can

I'm curious to know why you think there is a tcl connection? Not saying there isn't, just don't see it myself

How can you say that the arrival of Jesus changed the morality of the universe to be more merciful and forgiving with two world wars in the past 100 years?

I've read both of his other survey articles linked in the post. Judging by those this will certainly be interesting. Aaronson does a great job tying formal theory to applications and getting across a good mental model for the math he w

I don't know many other tcl hackers, and I'm really interested in what the community looks like right now. I put that there to drum up conversation with a tcl hacker.

Wow, very interesting. Thanks for pointing out picolisp!

Lisp is an interesting thing because once you learn it, you start seeing use cases for the ideas you've picked up during the process all over the place.

Yes, everything is a string. But you can pass data around anywhere you like without worrying about coercing. A command will receive its data in string representation and treat it however it likes. So when you go to do math with the 'ex

It matters because if the braces are not syntax, you can decide what code to execute as the condition body at runtime. set condition-body {puts "Hello, world"} if { $condition } $condition-body To get this to run, you

I have also heard that, but only from secondary sources. Here is a clip of Russell talking about the time he wrote the first lisp interpreter. He doesn't mention McCarthy being surprised, but he seems to imply that he, Russell, was qui

I just read a bit of documentation from the Picolisp page. It looks really cool, but can it reach arbitrarily far up the call stack? That's the quality of tcl that I don't see other places. The capabilities of 'upvar' an

This example of "everything as an expression" doesn't take it as far as Tcl, though. In the above code snippet, the conditional body is surrounded by braces, which are syntax. In Tcl, the second argument to the 'if'

Yeah the level of dynamicness (dynamism?) you can get in tcl is unparalleled as far as I can see. Having no types or syntax and access to the entire runtime at any point in the program opens up all kinds of crazy doors. But you're rig

If you like everything being an expression, check out tcl. A lot of ideas from lisp show up in tcl, especially the idea of everything as an expression. Tcl embodies this idea while also having the look of an algol-like language. Funny it ca

Nice article. Check out Paul graham's The Roots of Lisp for a similar exploration in which he shows how to build the metacircular interpreter. > John McCarthy wrote 6 easy things in machine code It was actually Steve Russel, McCart

This looks great. The compactness reminds me of Arc, with the bonus of having all of python's libs.

tcl is also written directly in the ast. And there is a built in command, expr, for doing infix math

This comment is a great representation of tcl's relevance, which is nice to see because tcl is often dismissed nowadays by people who don't understand it
