What is Lemmy?

Lemmy is a selfhosted social link aggregation and discussion platform. It is completely free and open, and not controlled by any company. This means that there is no advertising, tracking, or secret algorithms. Content is organized into communities, so it is easy to subscribe to topics that you are interested in, and ignore others. Voting is used to bring the most interesting items to the top.

Think of it as an opensource alternative to reddit!

Welcome to lemmy.net.au: Understanding Lemmy and How to Use It

Hello and welcome to our Lemmy instance! If you're new here, you might be wondering what exactly Lemmy is and how it differs from other social platforms. This guide will help you understand Lemmy's unique structure and how to make the most of your experience here.

What is Lemmy?

Lemmy is a forum-style social media platform (sometimes called a 'link aggregator') similar to Reddit or Hacker News. Here, you can:

  • Share and discuss links, text posts, and images
  • Upvote and downvote content to determine what rises to the top
  • Join communities centered around specific topics or themes
  • Connect with users across the entire "fediverse"

What Makes Lemmy Different: The Federated Approach

The key difference between Lemmy and traditional social platforms is that Lemmy is federated. Here's what that means:

Instead of one central website controlled by a single company, Lemmy consists of multiple independent websites (called "instances") that are all connected to each other. Each instance is run by different organizations or individuals.

Think of it this way: If Reddit is like a single massive shopping centre with one owner setting all the rules, Lemmy is like George Street in Sydney, which has multiple shopping centres, each with their own management but where shoppers can freely move between them.

The Power of Federation

When you join lemmy.net.au, you're not just joining this instance - you're joining the entire Lemmy network. You can:

  • Interact with users from other instances
  • See and participate in communities hosted on other instances
  • Keep all your connections even if you decide to move to a different instance

This means if you don't like how one instance is being managed, you can move to another without losing access to your favorite communities or connections.

How Lemmy Works in Practice

Communities and Usernames

In Lemmy, both communities and usernames include the instance name:

  • Communities are shown as c/CommunityName@instance.org
  • Usernames appear as @username@instance.org

For example, a community on our instance might be c/Australia@lemmy.net.au, while a user might be @JaneDoe@lemmy.net.au.

Accessing Content Across Instances

With your lemmy.net.au account, you can:

  1. Subscribe to communities from any federated instance
  2. Comment on posts from any federated instance
  3. Message users from any federated instance

When you find a community hosted elsewhere (like c/Programming@programming.dev), you can interact with it just as if it were hosted here.

Finding Communities

To discover communities:

  1. Browse popular communities on lemmy.net.au
  2. Use the search function to find specific topics
  3. Try the Lemmyverse.net search engine for more comprehensive results

Reddit to Lemmy: Translation Guide

If you're coming from Reddit, here's a quick reference to help you understand the terminology:

Reddit Term Lemmy Equivalent
Subreddit Community
r/example c/example@instance
u/username @username@instance
Karma Score
Moderator Moderator (same!)
Award Not available (no awards system)
Crosspost No direct equivalent, but you can share links to posts
Sorting by "Hot" Sorting by "Hot" (same!)
Sorting by "New" Sorting by "New" (same!)
Reddit Premium No equivalent (no premium tier)

Finding Communities

There are several ways to discover communities on Lemmy:

  1. Browse popular communities on lemmy.net.au
  2. Use the search function to find specific topics
  3. Visit lemmyverse.net - This is an excellent search engine specifically designed for Lemmy that allows you to search across all federated instances

Lemmyverse.net is particularly useful because:

  • It indexes communities across the entire Lemmy network
  • You can search by keywords, topics, or community names
  • It shows activity levels and subscriber counts
  • It allows you to discover niche communities you might not find otherwise

When you find a community you like on lemmyverse.net, simply copy its full name (including the instance) and search for it on lemmy.net.au to subscribe and participate. You might need to wait a few seconds after you search for the community to show up as the lemmy.net.au instance needs to connect to that instance and pull the information back.

Managing Your Experience

Blocking Content

If you encounter content you don't want to see:

  • You can block individual users
  • You can block entire communities
  • You can even block entire instances

If you believe a community or instance violates our community standards, please use the reporting function to alert the admin team!

Same Name, Different Communities

Sometimes you'll find communities with the same name on different instances (like c/News@lemmy.net.au and c/News@another-instance.org). These are separate communities with different moderators and potentially different rules.

This flexibility allows for diverse moderation styles and community cultures to coexist.

Getting Started

  1. Complete your profile - Add a bio and profile picture
  2. Find communities - Search for topics that interest you
  3. Subscribe - Join communities to see their content in your feed
  4. Participate - Comment, post, and vote to become part of the conversation

Mexico City. The Supreme Court of Justice of the Nation (SCJN) will review an unprecedented case in which Mayan communities in the municipality of Hopelchén, Campeche, seek to have bees recognized as subjects of rights—a legal status that would allow their caretakers to go to court to defend them and demand that authorities take action to protect them and prevent their deaths.

The case—an amparo review proceeding (file number 790/2025)—was formally brought before the Supreme Court this Thursday at the proposal of Justices Hugo Aguilar Ortiz (President of the Court) and Irving Espinosa Betanzo; the decision passed with eight votes in favor and one against, cast by Justice María Estela Ríos González.

“It allows us to examine the ancestral relationship between the Mayan community and bees—specifically, whether indigenous communities can act as guardians of nature and, in that capacity, bring legal action on its behalf—as well as to evaluate the standard of state conduct regarding the ecological crisis,” said Justice Espinosa.

Justice Arístides Guerrero García noted that exercising jurisdiction over this case would enable the Court to establish a precedent recognizing the Melipona bee—which is closely linked to the economic and cultural identity of Mayan communities in the municipality of Hopelchén—as a subject of rights or a legal entity deserving of protection within the framework of the comprehensive safeguarding of indigenous peoples, who have maintained a historic relationship with this species.

By popular demand from this post, here's the write-up for my version of that travel server.

The travel server is shown with the, currently, bare 5V UPS board to its right. One day I hope to have a 3D printed case for both of those, but they're currently separate as my 3D modeling skills are basically non-existent. The power cable is wrapped in aluminum foil and then wrapped in electrical tape due to EMI from the wifi adapter causing random glitches. A ferrite bead would probably solve that more elegantly, but I didn't have any on hand so made due with what I have.

Hardware

  • Banana Pi M4 Zero
    • 1.5 GHz Quad Core ARM64
    • 4 GB RAM
    • 32 GB eMMC
    • 1 TB Samsung PRO Plus SD Card (bought before prices went nuts)
  • Li-2B UPS Board + 2x 3,000 mAh 18650 batteries
  • USB-C to USB-A 90 degree angle adapter
  • USB Nano Wifi adapter

Note: Unlike the Pi Zero, these have two USB ports. One is configured in host mode and the other in peripheral mode.

Features and Capabilities

  • Multiple wifi clients can use this for network access
  • Multiple "WAN" options
  • Multiple VPN connections (OpenVPN, Wireguard, IPSEC) e.g.
    • Privacy VPN for general internet traffic
    • Wireguard to connect back to home network
  • Ad-blocking via PiHole
  • Locally-hosted web applications with valid hostnames and valid SSL certs (via Let's Encrypt).
    • SearxNG
    • Jellyfin
    • Pairdrop
    • CodeServer
    • Snapcast Server
    • myMPD (MPD web UI)
    • Kiwix (including full Wikipedia dump with images)
    • NodeRED
    • CalibreWeb

Travel Router / Access Point

For internet uplink, there are multiple options depending on need. By default, the internal/bulit-in wi-fi is the internet uplink and the USB wi-fi adapter is the client-facing AP interface. This is how I normally keep it configured in my use-cases.

Alternatively, the built-in wi-fi can be used as the client-facing AP and the uplink to the internet can be provided by a USB-tethered smartphone or a USB ethernet adapter or the internet uplink can be omitted entirely and either the USB or built-in wifi adapters can serve clients. Fortunately, the built-in wifi chip in the Banana Pi works well in AP mode but that's not always the case (cough Orange Pi Zero W2 cough).

If a PC is connected to USB0 (the OTG port), the device will act as an ethernet gadget. The travel server will add its end of the usb0 interface into the LAN bridge along with the client-side AP. This means the connected PC will be on the same LAN as the wireless clients.

It's also possible to add a USB ethernet adapter and bridge it into the LAN side as well.

Depending on configuration, a small USB-C hub may be needed. I've got one that includes a USB A port, ethernet port, and additional USB C port.

VPNs can also be configured as needed. I've got a privacy one that can route all traffic as well as a Wireguard one that connects back to my home LAN when I'm using it remotely.

DHCP and DNS are both provided by PiHole

Reverse Proxy

All applications hosted on the travel server are fronted by Nginx and use valid Let's Encrypt certificates. This eliminates the need to install a custom CA cert in end devices or have the clients accept an untrusted self-signed cert.

This also ensures all applications are protected by TLS which is required for full functionality of some applications.

How does that work?

The hostname of the travel server (mobile) is a subdomain of my personal, project domain (mydomain.xyz). All applications are a subdomain of that (e.g. application.mobile.mydomain.xyz), and I simply request a wildcard cert from Let's Encrypt for *.mobile.mydomain.xyz. Currently, Let's Encrypt requires the use of DNS validation when requesting wildcard certificates.

Movies/TV

Movies and TV shows are provided by Jellyfin and are stored on the 1 TB SD card. I've tested 4 simultaneous streams, and the travel server didn't even break a sweat. Granted, it's not transcoding anything so I believe I'm mostly limited by USB, wifi, and/or SD card bandwidth in that regard.

For reliability, the Jellyfin database is stored on the internal 32 GB eMMC rather than the SD card. This both reduces wear and tear on the card as well as proves to be more reliable.

CPU transoding is a non-starter, and the GPU drivers for these boards isn't exactly well supported. The GPU drivers also rely on V4L which Jellyfin has deprecated for hardware transcoding, so I opted to forego transcoding entirely.

To load movies/TV shows on here, I pre-process them with ffmpeg in the following way:

  • Scale to 720p to reduce space
  • Encode to H.264 in an MP4 container (including subtitles as mov_text if available) in yuv420p pixel format to avoid the need for remuxing or transcoding
  • Map only the English audio and subtitle streams to further save space

Music

Music is provided by a combination of MPD and Snapcast and the library is also stored on the 1TB SD card.

MPD manages the music collection while Snapcast allows synchronized multi-room audio and connecting receivers via wifi.

For local playback, I use myMPD web UI and use its streaming feed or use the MPD and Snapcast clients on the end device. There's also a Snapcast client installed on the travel server itself, so if you add a USB speaker it can playback music directly.

Books

It runs Calibre-Web to manage my book collection which is also stored on the 1 TB SD card.

Development

The travel server runs CodeServer which is an un-Microsofted web-based version of VSCode. You can set that up however you want, but I've got it setup for:

  • React / NextJS development
  • Python development
  • ESP8266/ESP32 development with Platform.io

Other services it runs to facilitate development include:

  • NodeJS and Bun
  • Postgres (via Docker)
  • Mosquitto MQTT
  • Redis
  • CouchDB
  • NodeRED

Offline Knowledge

Kiwix is installed with a large selection of ZIMS for offline reference.

  • DevDocs for React, Bun, NodeJS, ExpressJS, NextJS, etc. Pretty much every major libarary and framework I work with has offline docs
  • Full text Wikipedia dump with images (approx 130GB)

Search

I installed SearxNG so I always have an ad-free, AI-free, no BS search engine available.

File Sharing

The travel server has a few different ways to share files:

  • Samba (SMB) shared folder
  • PairDrop for quick and easy one-to-one local sharing in the browser or phone app
  • SSHFS (alternative method of accessing the SMB shares

Future Plans / Not Yet Implemented

  • Add data passthrough to the UPS board so a host PC can charge the UPS/power the travel server while also enumerating it as a USB ethernet device. Currently the UPS board only passes power.
  • Set up captive portal so Android (and probably Apple, too) devices don't freak out if there's no internet uplink. Currently requires an annoying "Stay connected to this network" and enabling airplane mode so that DNS will work over the wifi connection if there's no internet uplink available.
  • Make a web UI to manage services/configs. Currently, config changes require SSH-ing in and modifying the config directly. I do have preset configs for different "modes" but you still have to swap them around by hand.
  • Design and 3D print a case that can hold the UPS board and the travel server itself while allowing the travel server to be "ejected" (basically I imagine it slotting into it from the outside and connecting to fixed USB and mini HDMI connectors embedded in the case).

I sleep 10 hours a night but still need to nap constantly during the day. Even 400 mg of caffeine doesn't buzz me, it just makes me feel 70% close to my normal, high energy 20s self. My daytime fatigue is so severe I've been mistaken for being drunk (even though I don't drink), and I experience a dream like brain fog around friends unless I use caffeine pills to seem present.

I know this is part of normal aging for a woman in her 30s, but it's frustrating to constantly need naps when I haven't even done anything. Sometimes you just have to biohack. Still, I feel a bit jealous of how men age differently and seem to keep loads of energy.

Hello everyone! Daniel here.

Today, I'm excited to announce that Linkwarden is getting one of its largest mobile updates so far, along with a web app that’s much lighter to run.

For those who are new here, Linkwarden is a tool for collecting, organizing, reading, and preserving webpages, articles, and documents in one place. Linkwarden is available as a Cloud offering, or you can self-host it on your own server.

Let's get into it.

What's new on mobile:

🖍️ Highlight and annotate

You can now highlight text in the reader view, pick from four colors, and attach a note to any highlight.

There's also a new Notes & Highlights view per article which lets you skim what you've marked and jump to it in the text.

📥 True offline mode

Previously, the app only saved preserved formats for links you had already opened. Now, you can turn on Save for offline access in the settings, and the app will download every preserved format in the background as you browse.

🪪 Link details sheet

Long-press any link to open Link Details, which shows all the information about a link in one sheet, similar to the web app.

📖 Customizable reader view

Adjust font, text size, line height, and background color as you read.

What's new on the web:

🧠 Much lower memory usage

Linkwarden 2.15 roughly halves idle memory usage, from around 700 MB down to about 350 MB. We explained this in more detail on our blog.

🐳 A much smaller Docker image

The Docker image has also been cut in half, dropping from roughly 3.0 GB to 1.5 GB.

🔑 Generic OIDC provider

Self-hosters can now connect any OpenID Connect identity provider. Check it out in the docs!

🔒 Increased security

A good chunk of this release went into security hardening. We strongly recommend updating to 2.15.

There's more...

As always, there's a long tail of smaller improvements across the web and the mobile app.

Full Changelog: https://github.com/linkwarden/linkwarden/compare/v2.14.1...v2.15.0

Thanks!

Thanks to everyone using Linkwarden, reporting bugs, suggesting improvements, contributing to the project, responsibly disclosing security issues, and supporting its development. Your contributions genuinely shape every release.

If you'd like to try Linkwarden without dealing with server setup and maintenance, our Cloud offering is the easiest way to get started.

We hope you enjoy the latest Linkwarden updates!

  • A tire chemical called 6PPD-Q, already blamed for killing salmon, was examined for possible links to Alzheimer’s disease in a new computer-based study.
  • Using computer models, researchers found that the chemical can latch onto several proteins associated with Alzheimer’s and reach brain regions involved in the disease.
  • No patients or animals were tested; the study rests entirely on computer predictions and reused datasets, so it cannot prove the chemical causes Alzheimer’s.
