Thank you, yes that surprised me too. I know that they’ve made some improvements so I’m expecting them to be available in a newer release, then I’ll try it again.

Sorry, not sure how that happened! Yes, here it is: https://blog.polaris64.net/post/verlet-physics-playground/

I’m using Torsocks 2.3.0 and DiG 9.20.1

It could be the exit node that you’re using perhaps? Maybe you could try specifying a different exit node and trying again. Also check exit node policies to make sure DNS is allowed, although as your problem only seems to be with MX records then that might not be the cause.

I’ve just tried this (Tor version 0.4.8.12) and it seems to be working fine for me. I’ve tested with both 8.8.8.8 and 1.1.1.1.

…We did not want to contact FlyCASS first as it appeared to be operated only by one person and we did not want to alarm them. On April 23rd, we were able to disclose the issue to the Department of Homeland Security, who acknowledged the issue and confirmed that they “are taking this very seriously”.

I think the owner of FlyCASS was sufficiently alarmed!

A list comprehension is used to convert and/or filter elements of another iterable, in your case a range but this could also be another list. So you can think of it as taking one list, filtering/converting each element and producing a new list as a result.

So there’s no need to append to any list as that’s implicit in the comprehension.

For example, to produce a list of all squares in a range you could do:

[x*x for x in range(10)]

This would automatically “append” each square to the resulting list, there’s no need to do that yourself.

Common Lisp. I really enjoy the interactive development experience and the language itself (and macros). I feel though that the ecosystem isn’t very active and so existing libraries are often unmaintained which is a shame.

Welcome to Lemmy!

Here’s my Python script, it requires Python 3 and requests: -

def get_arg_parser() -> ArgumentParser:
    parser = ArgumentParser(
        description="Copy community follows from one Lemmy instance to another"

        dest="source_url",

        required=True,
        help="Base URL of the source instance from which to copy (e.g. https://lemmy.ml)"
    )

You use it like this (for example), assuming it’s saved to sync.py: -

python sync.py --source-url=https://lemmy.ml --dest-url=https://lemmy.world --source-jwt=abc123 --dest-jwt=bcd234

I think I remember reading about an existing project which aims to allow migration of followed communities, users, blocks, etc. between instances. I’d imagine that would be far cleaner than my quick solution so it might be worth a look!

I’ll try cleaning mine up though and I’ll post it here just in case it’s useful.

I did exactly this today. I wrote a quick and dirty Python script to fetch followed communities from lemmy.ml and to follow those same communities on lemmy.sdf.org (the current instance I’m using).
