dug VS LIPS

Just joined the sub after coming across it dozens of times while learning things to help my homelab. My first post is a shameless plug for a CLI tool I made that quickly helps users get an idea of how much their DNS has propagated. I use it all the time for my self hosted stuff (recently when i was playing with external-dns) and wanted to share to see if it can help anyone else. https://dug.unfrl.com https://github.com/unfrl/dug

For people who want to understand, learn about, or stay on top of their, DNS check out dug. Its a cli tool I made to help visualize DNS propagation but is a great learning tool.

Good article, totally correct that that is how to definitely 100% get the correct answer.

The bottom of the article, with 'other ways' got me thinking that another way to get what is very probably the correct answer is asking a bunch of other DNS servers what they think the correct answer is.

Using dug (https://github.com/unfrl/dug) like: dug -q NS jvns.ca

Gotta post this every time theres a big DNS issue, which seems daily now.

Check out Dug! Its a global DNS propagation/monitoring toolon the CLI: https://github.com/unfrl/dug/

This release is primarily focused on the 'Watch' feature (-w, --watch) which allows users to monitor their DNS propagation in realtime.

Sweet, I'll have to give that a go :)

Another option in browser land is lips[0], which exclusively targets a js backend.

For Scheme implementations there are LIPS and biwascheme. I haven't done more than play around with them, so I can't really give an informed opinion about pros and cons or favorites.

Your example revealed a bug in my Scheme interpreter. This is an example that fails to match:

In my interpreter, LIPS Scheme, vector literal syntax is created using a syntax extension, a token that is mapped to a function or a macro. So you can use things like this:

I'm not sure about other Scheme interpreters but in my interpreter LIPS Scheme, there is (env) function that returns a list of symbols. You can also access environment objects e.g. (current-environment) return object that is used internally. And you can even access the scope chain because the env object has __parent__ property that returns the parent scope.

Few of my Open Source projects: * jQuery terminal * LIPS Scheme * Gaiman * Sysend * Wayne

(define promise (--> '>(fetch "https://lips.js.org/") (then (lambda (res) (res.text))) (then (lambda (text) (. (text.match #/\s*([^>]+?)\s*<\/h1>/) 1)))))

ngl when I first saw the headline my first thought was, “Wait, bring CAR into JavaScript? Make it a Lisp? But hasn't it already been done?”

Languages like Biwa Scheme and LIPS Scheme are good for running Scheme in the browser. But I would prefer compiling Scheme code to JavaScript in the server, then serving the compiled JavaScript image to the browser.
