Found: it's a sentence from 2020, and PG decided not to appeal (!?) Full story (in Italian) at https://www.wired.it/internet/web/2020/06/30/progetto-gutenb...

From Italy, https://www.gutenberg.org/ gives a 404 error and https://gutenberg.org/ opens a very official-looking page stating "police notice. This site is under judicial seizure" …

> I am not familiar with the Scheme ecosystem but see you are implementing a lot within your shell (http client, sqlite support) what is great. Yes. Initially, I wanted to integrat…

Yes, they are similar at first glance. As I wrote: > If you know nushell, they will feel familiar as they are inspired by it - the implementation is fully independent, though. Look…

First stable release appeared on HN one year ago: https://news.ycombinator.com/item?id=43061183 Thanks for all the feedback! Today, version 1.0.0 adds structured pipelines: a mecha…

Parents already have a lot of control on children' education. Examples: most children believe in the same religion as their parents, and can visit friends and places only if/when a…

I am from EU, and contrary to age verification laws in general. My stance is that if somebody is a minor, his/her/their parents/tutors/legal guardian are responsible for what they …

I need this *so* often that I programmed my shell to execute 'cd ..' every time I press KP/ i.e. '/' on the keypad, without having to hit Return. Other single-key bindings I use of…

The math looks suspicious to me, or at least how it is presented. If, as stated, accessing one register requires ~0.3 ns and available registers sum up to ~2560 B, while accessing …

For me it's more about "feeling" badly written code, as if it stinks and is unpleasant to look at, and conversely enjoying nicely written one, and seeing its elegance and beauty. E…

> So, people who use native REPLs, what do you do with them? In my case, I use my interactive shell https://github.com/cosmos72/schemesh every day as login shell. You can look at i…

I tried compiling https://github.com/panzi/ansi-img and running it inside the truecolor branch of twin, i.e. https://github.com/cosmos72/twin/tree/truecolor and it correctly displa…

You can choose the font with `twin --hs=X11,font=X11FONTNAME` or `twin --hw=xft,font=TRUETYPEFONTNAME` I will have a look too, the terminal should not crash or stop being responsiv…

If you mean the Unicode glyphs listed at https://en.m.wikipedia.org/wiki/Block_Elements they are supported - you just need a display driver that can render them. For example, `twin…

Yep, I am well aware of the `;` vs `:` confusion in both 256 color and 24-bit color control sequences. Short of hand-coding "which terminal supports which variant" I do not know an…

Author here :) I've been using Twin as my everyday terminal emulator and terminal multiplexer since ~2000, slowly adding features as my free time - and other interests - allowed. A…

For optimal speed, you should move as much code as possible outside the closures. In particular, you should do the `switch op` at https://github.com/skx/simple-vm/blob/b3917aef0bd6…

The core idea is simple: do a type analysis on each expression you want to "compile" to a closure, and instantiate the correct closure for each type combination. Here is a pseudoco…

Compiling an expression to a tree of closures, and a list of statements to a slice of closures, is exactly how I optimized [gomacro]( https://github.com/cosmos72/gomacro ) my Go in…

You mean a command or builtin `(` inside a traditional shell as bash or zsh? It would be quite limited: internal status would not persist between invocations, and it would only be …

That's true. In shells, "test" and "[" are often used after "if", as for example if test -f "some_file" do_something fi if [ "$FOO" != "" ] do_something_else fi Schemesh does not h…

[UPDATE] (shell-expr) is ready and kicking :) Now you can write (import (schemesh all)) (shell-expr (lisp-expression-writing-to-sh-fd-stdout)) | some-shell-command-and-args | (shel…

Yes, that's definitely feasible. I am currently working on it, the macro will be named (shell-expr) and replace the current experimental (shell-test)

Porting to a different Scheme implementation requires some effort: schemesh needs a good, bidirectional C FFI and an (eval) that allows any Scheme form, including definitions. For …
