My replies via Mastodon to Lemmy posts don't get distributed as expected. For example:

• Original post: https://lemmy.ml/post/11552444
• A reply via Lemmy: https://ttrpg.network/comment/4965852
• My reply to that: https://hachyderm.io/@otl/111887721960075860

It seems my reply only shows in these Lemmy servers:

• lemmy.ml (the server of the group to which the post was made)
• lemmy.world (the server of the post's author)
• ttrpg.network (the server of the comment's author)

From some other lemmy servers, my comment is not present:

• lemmy.sdf.org: https://lemmy.sdf.org/comment/8124910
• lemmy.one: https://lemmy.one/comment/6912806
• aussie.zone: https://aussie.zone/comment/6414209

I expected that my reply would show on any other Lemmy server with subscriptions to [email protected]. Does that make sense? I'm hoping to help troubleshoot federation like this as I'm super excited about ActivityPub and what it means for the internet! :)

One of my favourite talks on programming. Just wanted to share for others who haven't seen this before.

https://www.crikey.com.au How is it?

Last year I gifted a news junky friend a year subscription to the New York Times. That was cool but they are more interested in Australian stories. Normally they browse the ABC and BBC apps.

With Github so popular now, not everyone is aware of the workflows that git provides out-of-the-box for collaboration. Thought this may pique some people's curiosity :)

Let’s share stories where your automation efforts have been rejected and you can’t quite understand why! Here’s mine.

Coming to you from my iPad and my old mechanical keyboard plugged in via a USB-C adapter! Go to Settings -> General -> Keyboard -> Hardware keyboards Finally select the language then scroll down to Colemak!

My girlfriend is using the desktop to watch a movie and I wanted to type something up. Never thought I could do it on my iPad but here we are :)

Just wanted to let you all know. Not sure how long this has been possible for; pretty sure it's only possible if you've got a physical keyboard connected via USB or Bluetooth.

Hello, world!

The design goal of Pikchr is to enable embedded line diagrams in Markdown or other simple markup languages.

Cool project. Created by the same group as SQLite. The scripting language is based on pic(1) but outputs SVG instead of troff.

TL;DR Seeking any advice on making documentaries about things around me!

I've done a couple of short videos as a hobby between jobs. I'm a programmer by trade. It was really fun to make these in particular:

• a short documentary [Backpackers In Cairns, Australia During the COVID-19 Pandemic]
• a group profile of the [NSW Carriage Driving Society].

But these take time that I don't really have any more; I've got a girlfriend and we don't want to spend all that time on the road! I tried to shoot a couple of 90-second news packages for a local news website but it was really hard. I hate politics and I hate that breaking news cycle.

Off the top of my head, here are some things that I think would be fun to shoot and edit:

• Documenting local organised events. Not just the highlights; from setting up and packing down again, mishaps along the way.
• From bin to...? Where our rubbish goes
• Cancelled buses: why bus drivers are so hard to find

I feel embarassed to speak to people about

Lemmy uses the packages olowe.co/lemmy (source), which provides a io/fs filesystem interface to a Lemmy instance, and 9fans.net/go/acme to interact with acme. What you get is an Acme Mail inspired program for Lemmy. As you can see, it's a work in progress!

But it's been fun so far. Sorry that this isn't running on Plan 9 (running on OpenBSD). I'm on the road at the moment and don't have a way to connect to a server right now!

I recently wrote a command-line utility [lemmyverse] to find communities indexed by [Lemmy Explorer]. A quick count shows almost 14%(!) of all communities indexed by lemmyverse are junk communities created by a single user @LMAO ([reported here]):

 undefined

        % lemmyverse . | wc -l
      30376
    % lemmyverse enoweiooe | wc -l
       4206


  

Here's a python script, using no external dependencies, which uses Lemmy's HTTP API to delete all communities that @LMAO moderates:

 undefined

        #!/usr/bin/env python

    import json
    import urllib.parse
    import urllib.request

    baseurl = "https://lemmy.world"
    username = "admin"
    password = "password"

    def login(user, passwd):
        url = baseurl+"/api/v3/user/login"
        body = urllib.parse.urlencode({
            "username_or_email": user,
            "password": passwd,
        })
        resp = urllib.request.urlopen(url, body.encode())
        j = json.load(resp)
        return j["jwt"]

    def get_user(name):
        query = urllib.parse.urlencode({"username": name})
        resp = urllib.request.urlopen(baseurl+"/api/v3/user?"+quer
  

lemmyverse: search lemmy communities from the command-line. Thanks to the data HTTP API from [lemmyverse.net]! This is not really as polished as I like but, hey, in the interest of having a lively Lemmy I thought I'd share anyway :)

Usage

lemmyverse searches community names and descriptions using a regular expression:

 undefined

        lemmyverse pattern


  

Find communities about motorcycles:

 undefined

        $ lemmyverse motorcycle

    [email protected]     All Things motorcycles
    [email protected] Community for BMW motorcycles. A place to share
    [email protected]       A community to discuss all things BMW cars & motorcycles.\nFeel free to show off your new vehicle/parts
    [email protected]       A discussion area for Buell motorcycles.

Go tech lead Russ Cox:

This post is about why we need a coroutine package for Go, and what it would look like.

With a post like this it usually means there will almost certainly be a new standard library package. But even more interestingly:

If we are to add coroutines to Go, we should aim to do it without language changes. That means the definition of coroutines should be possible to implement and understand in terms of ordinary Go code. Later, I will argue for an optimized implementation provided directly by the runtime, but that implementation should be indistinguishable from the pure Go definition.

Go project tech lead Russ Cox talks about a technique to make programs clearer using concurrency.

An OpenBSD developer and the one-man-band behind Pushover gives some advice after 10 years of running a public HTTP API. It's interesting as big companies are happy to publish articles about all the fancy stuff they developed to run some API, but you don't always hear from a sole developer running a service for such a long time.

There's something about the consistency that is missing nowadays.
