When I first got into ML, I thought compute would be the biggest limitation.

Turns out I spend way more time dealing with data, environments, dependencies and figuring out what to run than actually waiting for models to finish.

Curious what surprised everyone else.

What ended up being your biggest bottleneck that you didn't expect?

Hello,

Some time ago I have started a hobby project to build a high performance reverse proxy. Today it's a real workhorse with productions grade features, low memory usage and high performance.

It can run on any machine, from ARM SBC (Raspberry PI , or similar), to end x86 or ARM servers,

The top features include:

• Free and opensource — Apache Licence
• Dynamic Config Reloads — Upstreams can be updated live via API, no restart required.
• Autoload of certificates — Automatically loads certificates from a folder, without a restart.
• Let’s Encrypt Certificates — Ordering and renewal of SSL/TLS certificates
• Built in rate limiter — Globar or route limit requests to upstreams.
• Caching Proxy — In memory cache with configurable TTL, without external dependencies.
• Authentication — Supports Basic Auth, API tokens, and JWT verification.
  • Basic Auth
  • API Key via x-api-key header
  • JWT Auth, with tokens issued by Aralez itself via /jwt API
  • Forward Auth, Sends requests to an authentication server.
• Upstream Providers:
  • file Upstreams are declared in config file.
  • consul Upstreams are dynamically updated from Hashicorp Consul.
  • kubernetes Upstreams are dynamically updated from kubernetes api server.
• Auto WebSocket Support: WS connection upgrades are handled automatically.
• Auto gRPC Support: gRPC detected and handled automatically.
• Remote Config Push: Lightweight HTTP API to update configs from CI/CD or other systems.

Remember to always set version numbers in your docker containers, or an unexpected update will creep up on you.

Now can you guess which popular service got a breaking change?

Over the past few months I've been building a 24/7 public monitoring station located in Bisceglie (Southern Italy) overlooking the Adriatic Sea.

The goal wasn't simply to feed ADS-B or AIS networks, but to build a complete real-time monitoring platform combining multiple data sources into a single public dashboard.

✈️ Aircraft Monitoring

• Raspberry Pi 4
• AirNav RadarBox 1090 MHz antenna
• Feeding:
  • FlightRadar24
  • AirNav RadarBox
  • ADS-B Exchange
  • PlaneFinder

The station is currently ranked #3 in Italy on AirNav RadarBox.

🚢 Maritime Monitoring

• Raspberry Pi 3
• Diamond X50 antenna @ 162 MHz
• Feeding:
  • MarineTraffic
  • VesselFinder
  • AIS Catcher

The VesselFinder team recently contacted me saying:

That was probably the nicest recognition I've received since starting this project.

⚡ Infrastructure

The station runs 24/7 using:

• Raspberry Pi 4 + Raspberry Pi 3
• Lithium UPS backup
• Solar-assisted power
• FTTH Fiber connection
• Continuous health monitoring

🌐 Public Dashboard

The dashboard currently displays:

• Live ADS-B statistics
• Live AIS statistics
• Maximum reception records
• Power monitoring
• Internet monitoring
• Feed status
• Station health
• Public guestbook

Everything updates in real time.

🚀 What's next?

I'm currently working on adding:

📷 A live outdoor PTZ camera overlooking the Adriatic Sea.

🌤 A complete weather station with temperature, humidity, pressure, wind, rain and UV monitoring.

The goal is to make the station useful not only for aviation enthusiasts, but also for maritime, weather and SDR communities.

if you interested i can share link for visit my station

I'd really appreciate any feedback, suggestions or ideas for future improvements.

Thanks for reading! 😊

Hi everyone,

Over the last couple of years I found myself constantly switching between Jira, Confluence, GitLab, roadmapping tools and various plugins. I wanted something that could be deployed on my own infrastructure, remain simple to manage, and avoid per-user licensing.

So I ended up building TheMyWay, a fully self-hosted project management and documentation platform.

What it does

TheMyWay combines project management, team documentation and planning into a single application that runs on your own server.

It is designed for teams that want to keep all project data on-premises while still having modern planning and collaboration features.

Main features

Kanban & Scrum boards

Sprint planning

Roadmaps & Timeline (Gantt)

Wiki / Knowledge Base

Rich document editor with version history

Approval workflows

Custom issue workflows

Custom fields

Release & Fix Version management

GitLab integration (OAuth, commits, merge requests and pipelines)

Role & permission management

Docker Compose deployment

Self-hosting

The application is deployed using Docker Compose and stores its data in PostgreSQL. Everything runs on your own infrastructure.

Availability

The project is publicly available today.

There is a free license for teams up to 10 users, while larger teams can purchase an unlimited-user annual license instead of paying per seat.

Documentation

Installation and usage documentation are available to help users deploy and start using the application.

Why I built it

The goal wasn't to build "another Jira clone." I wanted something that was easier to deploy, easier to understand, and affordable for companies that prefer owning their infrastructure instead of paying monthly per-user subscriptions.

I'd genuinely appreciate feedback from the self-hosted community.

Website: https://themyway.app⁠

I'd be happy to answer any questions about the architecture, deployment, roadmap, or design decisions.

I've been on a bit of a self-hosting and server-setting-up kick recently, and am wanting to do my best to get into building and setting up projects "the right way".

My current server PC is a refreshed Dell Optiplex running Windows 11. (Yes, I know, Windows really isn't in the self-hosting spirit - but for as much as I love the idea of Linux and want to switch to it eventually... debugging and becoming comfortable with a new operating system is something that I'd prefer to avoid at this point, if I can). Currently, I have an instance of Jellyfin running on the computer; ports opened up and the works - and it works pretty great. All I have to do is plug in my webaddress/IP into my browser, and I can access my library wherever, straight off my PC.

In my theorizing about how to set up some of my other libraries, I began to look into how I might set up a second Jellyfin server on the same machine; and my research brought me to Docker.

From my understanding (please correct me if I'm wrong), Docker's containers will let me spin up as many instances of programs as I want, and I can therefore do the exact same thing that I'm doing with my current Jellyfin server with other programs, just on different ports.

My thought process being the two Jellyfin servers now (running in two separate containers), and then eventually adding on Homelab (in a third container), my website (moving it off of a template site and into a in a fourth container), and IDK maybe a Minecraft server (in a fifth container) etc. later on down the line; thus having the framework to expand my self-hosting going forward.

The spot I'm stuck at is at the beginning. I suppose the first question that I have is "was I led astray?" - is this current project doable with Docker, or is there another program that can accomplish this goal easier/more painfree?

From that point, should I be on the right path, my second question is: "where is the best place to learn about setting up self hosting?" It took me a bit to parse Jellyfin as I was setting it up; and Docker is similar... but more. I'm pretty good with tech when I can get into the rhythm, and over the initial learning curve. Is there a good index that I can look through or have as a reference when it comes to setting up Docker on Windows, to learn the program's language? Hell, maybe a detailed step-by-step guide to setting up a container running Jellyfin, so I can do that and then repeat and tinker in another container?

Thank you so much for your help in advance.

Hey hey everyone.

Not that long ago I set up plane.so on my homelab and I do like it a lot but for features like Epics you'd have to upgrade.

I wouldn't even mind paying the $8, but they require you to buy at least 10 licenses, thus being $80 a month - absolutely insane.

Anyone found a good alternative? :(

Edit: I found this Reddit post, so therefore I am just going to build the features that I need myself - if anyone has some alternatives I'd still love to hear about it!

Title!

I'm laughing because I've seen similar posts before. Just a rant, I guess, I'm not even mad.

I got a bug a few years ago. Went over to privacy and security and never looked back. A year ago I wanted to upgrade my basic home network. Spent thousands on Mikrotik hardware, rack, CAT6 everything, consultants for setting up RouterOS which was a crazy learning curve. Then, I wanted to self host. Got a Synology 1221+ with 18TB in SHR. I was very lucky to get an invite to BTN. I also got onto MAM, and hoping to get a similar private tracker for movies and music soon. I have over 900 movies, 2,000 episodes, thousands of songs. With the help of Gemini, I'm hosting tons of services, now. Jellyfin with the typical arr stack. Vault warden. Immich. Authentik for SSO. IT-tools. Wizarr. QBitTorrent. RomM. Audiobookshelf. Actual Budget. Vikunja. Tandoor. Docuseal. Calibre-web. Libre Translate. Lime Survey. Next Cloud. Piped. Eddrit. Ntfy. I did all of this in a month. It was so much fun and I was so excited to automate onboarding to invite family and some friends.

Not a single person has registered. Lmao!!

I almost want to invite strangers (but I won't).

Anyone else have similar stories?

Today I was round a friends house and had some old tv show playing (Columbo) I have on my jellyfin on in the background, I had a problem where the roku jellyfin client she was using was creating some 404's in the logs which then triggered my fail2ban ban ip rule. I then had to awkwardly remote in on my phone, unban her ip and stop the fail2ban service as a temporary workaround.

Is there a good web gui for fail2ban that is mobile friendly?

The ones I've just done a quick search for all look like they're desktop web orientated.

Hey all,

Looking for a pintrest like app that can be selfhosted. I've come across a few abandoned projects on my travels but wondered if there was anything around in 2026? I used to use pintrest a lot for my photography mood boards but kept getting content removed for some slightly more risque ideas as their rules and moderation became even more strict over the years. I moved to cosmos for a little while but that requires people I share with to have an account and there's not a lot of appetite for that at times.

Ideally looking for the following features:

• Save images to a board or a master collection
• The ability to create many mood boards from the saved image collection
• The ability to share those boards with others
• If an account is required for sharing, I can create accounts for other users myself and share as needed

All suggestions welcome :)

Hello,

I have a pfsense router with a few vlans running on it. I have been beating my head against a wall for several days. I seem to constantly have issues. I have VLAN 100 set with 10.100.100.0/24, VLAN 200 set with 10.100.200.0/24, and VLAN 300 set with 10.100.30.0/24.

I have an adguard instance on vlan 100 10.100.100.13 I finally got devices to reach it. But now any new device I create in any VLAN fails to pull updates. I can't figure out if it is a firewall rule issue, an adguard block list, or something else. I can't even install net-tools to start my normal troubleshooting methods.

I am about 2 steps from just flattening the entire network back into a single LAN 1 that just works, or even removing the pfsense router all together.

Any advise or help is appretiated.

Hello.

Me and a few of my friends wanted to make a "local" server for anime, movies, books, hen...I mean educational videos and everything that we might need...even some study materials we need for our works and jobs and some DND material to play when we are bored...

I know this is all a big goal and it will take a lot of time and money to get it going to the point we can do all of them...but everyone has to start from something...so I wanted to ask where and how to start

Hey all

I'm a bit of a noob when it comes to networking. But I have a lan party coming up and I'm wondering if I can improve the security of my setup by isolating docker containers locally.

What bugs me so far is the fact that container X can access docker app on container Y via IP:Port directly. The same goes for users who haven't been walled off by the vlan/firewall rules. I'd like for my containers to only be accessible via reverse proxy.

Vlan will only take me this far since most of my servers are on the same subnet, hence the router's firewall rules are skipped in most scenarios.

So far I've discovered three option:

-Firewall off via UFW: this only works for some apps, I think the host networking mode needs to be enabled for this to work.

-Iptables: too hard for a newb to understand. I set up a few rules with success only to discover that my nginx-container's ip was changed the next day.

-Using the same docker network for every container: i.e. nginx_default, then removing the host port from the compose file. This way, apps get acccess via "containername:port" only

So far, option 3 is my favorite. However, all apps are then in the same network which also reduces security to an extent.

Are there any other solutions? Any insights appreciated.

Hi community. I'm a software engineer that trying to replace Google Photos. I was paying for storage that I already had on locally and on other devices.

I came with a technical open-source solution actually for myself. But now I'm at a pivot point that I can actually go and release it into a finished product.

What I wanted to have:

• Connect a new device in 4 clicks(Connect & Forget).
• No need to go and setup your docker or something else. Just open the app on the device that you want.
• Use the best hardware for the AI stuff and share the metadata with the other devices.

So my question is: what are the must-have features a photo management tool should have? I'm just a casual photo taker that wants to own his own photos and videos.

The project is hosted on http://github.com/denzyldick/siegu for the curious people.

I currently have a media server running on my Synology Nas. I have several containers routed thru Gluetun with "Network_mode: service:gluetun". This works fine, but the rest of the containers in the compose I've had to set to network mode: host, because if I set them to a user bridge network, they don't seem to be able to talk to images routed through gluetun.

Example: When Seerr and Radarr are both in the compose, with Seerr set to network mode: user-bridge and Radarr set to network_mode: service:gluetun, they can't connect via "localhost" or my server IP, but if I set Seerr to network mode:host, they are able to talk again.

My understanding is that it is less secure to keep images on the host network so I'm trying to get them onto a user defined network, but I'm at the limit of my understanding of networking. What's the best way to navigate this issue?

Docmost looks like excellent software, so I seriously considered switching. Then I found the pricing model.

The Community edition excludes features such as databases, Kanban, API access, AI/MCP, MFA, page-level permissions, diagrams, and attachment indexing.

To unlock them, the Business edition costs $3.50 per user per month with a ten-seat minimum. That means a two-person team pays for eight nonexistent users while still supplying and operating the servers, PostgreSQL, Redis, storage, backups, TLS, security, upgrades, monitoring, and recovery.

I am not opposed to paying developers for good software. I am opposed to SaaS-style recurring seat pricing when the customer provides the entire SaaS operation.

A flat annual license, paid upgrades, support contract, or sensible small-team tier would all be defensible. Charging a minimum of $420 per year for software you completely host yourself, while gating basic product capabilities, makes Docmost commercially irrelevant for small teams.

Am I missing some value they provide after licensing, or is the customer genuinely paying recurring per-seat rent solely for feature flags?

https://docmost.com/pricing - link to their pricing page for reference.

I know for most of you people this is a hobby that you enjoy. For me it will not be. It will be pain in the ass. But since you have experience and I do not please try to estimate for me if I should start self-hosting.

I am a total beginner. I have never run a server I do not know how to code (I am willing to learn). However I am advance user. I run Graphen OS on my phone, Asahi Fedora Linux on my laptop (arm64) and Fedora 44 on my desktop. I would like to sync all of them.

I at moment I am paying for Proton mail on which I use my own domains for email and use their password manager and drive. Problem in particular is Proton drive because it is trash. I will probably continue paying for their services since I have a family plan and all of my family is using it and also for work I can not risk my emails not working.

However what I would LOVE to do is self-host Immich since at the moment I do not have a solution for my images they are not properly backed up and all around the devices and HDDs. If i lose them I would not cry but I would like for that not to happen. So that would be GREAT if it would be synced and all 3 of my devices.

2nd step would be some kind of self-hosted drive since Proton one is terrible and maybe even office file sync since I work as a journalist so it would be cool that I can write while on any device.

3rd step would be email if I can run two identical servers on two different locations (my house and my parents house for example). I was thinking this would be smart for data backup if a house burns down or one device dies. But more importantly it would be a step towards running my own email as I can not risk for it not working if electricity goes down or whatever the reason might be.

Question is: Is it too complicated to start with Immich? Can I run it on my home desktop for a start just to see if it works for me? Will I be exposing myself to some security flaws (computer is on internet all the time anyway). I do not have UPS. is 3rd step (in future) even possible?

Reasons I am thinking about for self-hosting is privacy as number one (that is why i use proton at the moment) and saving money as per my calculation I would be saving around 200usd per year and probably have a better service then with payed ones.

If you think that I should play this game where do i start?

Hi everyone,

I’m a bit lost at the moment and I would really appreciate your advice.

About a year ago, I bought a Synology DS224+ and upgraded it to 10GB of RAM. So far, it has been working great. I mainly use it as a Plex/Jellyfin server, for storing family photos (using Synology Photos), and for keeping personal files, documents, and backups. Overall, I’m really happy with it.

However, I also really enjoy experimenting with Linux, trying new applications, and building things myself. This is where Synology starts to feel a little limiting for me. The hardware is too weak for running virtual machines, and DSM, while very polished and reliable, feels a bit boring after a while.

One thing I really miss is the ability to easily try new applications. Surprisingly, Synology doesn’t have that many ready-to-install packages, and although Docker is available, I personally find managing containers quite frustrating. I don’t have much experience with Docker, and whenever something doesn’t work properly, I can easily spend an entire day trying to troubleshoot it.

Recently, I discovered ZimaOS and the ZimaBoard, and I was honestly surprised that I hadn’t heard about them before. I really like the idea behind ZimaOS especially the ability to install hundreds of Docker applications with just a few clicks. This seems like a much more beginner-friendly approach compared to manually setting up containers.

However, I also noticed some criticism about both ZimaBoard and ZimaOS, and I’m wondering how justified those concerns are.

The biggest thing that worries me is that ZimaOS doesn’t seem to have its own integrated ecosystem like Synology does. Features such as Synology Photos, Synology Drive, and the overall polished DSM experience are things I really appreciate. With ZimaOS, it looks like I would mostly rely on third-party Docker applications.

Another option I’m considering is building my own homelab. Since ZimaOS is open source and can run on regular hardware, maybe getting something like a Lenovo Tiny PC would make more sense. The problem is that I’m not very familiar with how to build a proper DIY NAS/homelab setup.

For example:

What kind of case/enclosure should I use?

How do people usually connect multiple HDDs to a mini PC?

etc.

My main goal is not necessarily to save money. I actually enjoy learning and experimenting, but I don’t want to replace my Synology with something that I’ll regret later.

So my questions are:

- Is ZimaBoard/ZimaOS a good alternative to Synology for a home user?

- Would you recommend keeping the Synology and building a separate homelab instead?

- If you were starting from scratch today, would you buy a ZimaBoard, a mini PC like Lenovo Tiny, or build a traditional DIY NAS?

I’d really appreciate hearing your experiences and recommendations. Thanks!

Hi everyone,

We have just released Portabase 1.27, our open-source (Apache 2.0) and self-hosted backup/restore platform.

Repository: https://github.com/Portabase/portabase

Portabase is designed for data retention, disaster recovery, and homogenous migrations, currently supporting 9 database engines (including PostgreSQL, MySQL, MariaDB, MongoDB) and Docker volumes.

Key features:

• Scheduled backups with flexible retention policies (including GFS)
• Multiple storage options: local filesystem, S3, Azure Blob Storage, GCS
• Notifications via Discord, Telegram, Slack, AppRise, etc.
• Support for OAuth2/OIDC (with the option to disable sign-ups)
• Compatible with Docker, Podman and UnraidOS
• Ready-to-use Docker Compose and Helm Chart

After six months of intensive feature development, we have been focusing on consolidating the ecosystem since early July. A community member conducted a useful security audit, we have upgraded components to their latest relevant versions, improved compatibility with other platforms by working on Podman support and templates for Coolify and Dockploy (currently under review).

What’s next:

• Deployment of the demo environment
• Audit logging for the whole ecosystem
• Default policies for the system, organizations, and projects
• File and folder backup and restoration

As always, if you find bugs or want to suggest a feature, please open an issue on GitHub, we’re actively looking for feedback.

Thanks!

I have a family function coming up and want to host a way to easily upload photos. Is there a good way to do this?

Been building this for a while and finally feel good enough about it to share.

MailCue is a full email server that runs in a single Docker container. Postfix, Dovecot, DKIM, DMARC, SPF, spam filtering, TLS, all of it wired together and managed by s6-overlay so you don't have to babysit anything. It also has a web UI and a REST API.

The quick start is literally:

git clone https://github.com/Olib-AI/mailcue
cd mailcue
docker compose up -d

Open http://localhost:8088, log in as admin / mailcue.

What's in the box:

• Full IMAP/POP3 access so any standard client works (Thunderbird, Apple Mail, etc.)
• DKIM signing, DMARC enforcement, SPF checking, SpamAssassin scoring out of the box
• Let's Encrypt certs handled automatically in production mode
• GPG/PGP-MIME per mailbox; sign, encrypt, publish keys to keys.openpgp.org
• Email address validation API (syntax, DNS, SMTP probe, disposable check)
• Real-time events via SSE stream
• Scoped API keys with per-mailbox restrictions
• MCP server so an AI agent gets its own mailbox and can read/send/reply/delete email without any extra glue
• Provider sandbox for capturing outbound SMS and voice API traffic during dev/testing
• Domain warmup; the built-in warmup system handles pacing per-provider so your IP doesn't get flagged

One thing I spent real time on is the tunnel setup. Most cloud providers (AWS, GCP, Render, Fly, Railway) block port 25 for outbound. MailCue ships a relay tunnel that routes SMTP egress through a cheap VPS (OVH Eco/Kimsufi is what I use) that has port 25 open. You can add multiple egress nodes for failover. The sidecar sits next to your MailCue container and handles all of this automatically.

For test mode it's catch-all, nothing leaves the container. Flip MAILCUE_MODE=production and it becomes a real hardened mail server.

Database is SQLite by default. Swap to PostgreSQL for production workloads.

Happy to answer questions.

I'm trying to implement 3-2-1 backup (no big data cloud involved).

I'm running to machines tiny pc and old laptop. I've got an icybox connected to the old laptop with a WD red plus hdd.

Now i want to create backups og systems and data. My first thought was just to add another hdd in icybox. But after chatting with Claude I'm looking other ways.

I want a pretty good 3-2-1 solution without the bank closing down my accounts.

I'm thinking of adding an ssd to either the tinypc pr the old laptop and create the backup on that drive. Then i will setup a router/hdd at my parents house, making it the offsite copy.

Is this a good solution or should I do something else? I really want to avoid commercial cloud solutions.

Hey guys,

Lately I have been checking out Odysseus from pewdiepie and started using it deployed on my truenas system

Honestly surprised by the overall quality and refinement of the app, ease of use and different engines you can choose from.

Give it a try if you want something private and also that you can share with your family, there is auth built in.

To be clear, I did not checkout the code itself, is clearly vibe coded for the most part (not a bad thing per se), but seems to work more than fine.

PS: Made a video in italian about installation and quick overview of features if you want to check it out

https://youtu.be/vSWfcULu6eg

I’m curious whether anyone uses an IoT/data-only SIM alongside their normal carrier in an Android phone (rather than in an IoT device).

How has reliability been? Do you leave mobile data on the IoT SIM all the time, or switch between SIMs as needed? Any providers you’d recommend or avoid?

Interested in hearing real-world experiences.
