Faizul "Piju" 9M2PJU: Docker vs Virtual Machines: What Every Ham Should Know

Sun, 05/04/2025 - 01:47

Before container technologies like Docker came into play, applications were typically run directly on the host operating system—either on bare metal hardware or inside virtual machines (VMs). While this method works, it often leads to frustrating issues, especially when trying to reproduce setups across different environments.

This becomes even more relevant in the amateur radio world, where we often experiment with digital tools, servers, logging software, APRS gateways, SDR applications, and more. Having a consistent and lightweight deployment method is key when tinkering with limited hardware like Raspberry Pi, small form factor PCs, or cloud VPS systems.

The Problem with Traditional Software Deployment

Let’s say you’ve set up an APRS iGate, or maybe you’re experimenting with WSJT-X for FT8, and everything runs flawlessly on your laptop. But the moment you try deploying the same setup on a Raspberry Pi or a remote server—suddenly things break.

Why?

Common culprits include:

  • Different versions of the operating system
  • Mismatched library versions
  • Varying configurations
  • Conflicting dependencies

These issues can be particularly painful in amateur radio projects, where specific software dependencies are critical, and stability matters for long-term operation.

You could solve this by running each setup inside a virtual machine, but VMs are often overkill—especially for ham radio gear with limited resources.

Enter Docker: The Ham’s Best Friend for Lightweight Deployment

Docker is an open-source platform that allows you to package applications along with everything they need—libraries, configurations, runtimes—into one neat, portable unit called a container.

Think of it like packaging up your entire ham radio setup (SDR software, packet tools, logging apps, etc.) into a container, then being able to deploy that same exact setup on:

  • A Raspberry Pi
  • A cloud server
  • A homelab NUC
  • Another ham’s machine
Why It’s Great for Hams:
  • Lightweight – great for Raspberry Pi or low-power servers
  • Fast startup – ideal for services that need to restart quickly
  • Reproducible environments – makes sharing setups with fellow hams easier
  • Isolation – keeps different radio tools from interfering with each other

Many amateur radio tools like Direwolf, Xastir, Pat (Winlink), and even JS8Call can be containerized, making experimentation safer and more efficient.

Virtual Machines: Still Relevant in the Shack

Virtual Machines (VMs) have been around much longer and still play a crucial role. Each VM acts like a complete computer, with its own OS and kernel, running on a hypervisor like:

  • VirtualBox
  • VMware
  • KVM
  • Hyper-V

With VMs, you can spin up an entire Windows or Linux machine, perfect for:

  • Running legacy ham radio software (e.g., old Windows-only apps)
  • Simulating different operating systems for testing
  • Isolating potentially unstable setups from your main system

However, VMs require more horsepower. They’re heavy, boot slowly, and take up more disk space—often not ideal for small ham radio PCs or low-powered nodes deployed in the field.

Quick Comparison: Docker vs Virtual Machines for Hams Feature Docker Virtual Machine OS Shares host kernel Full OS per VM Boot Time Seconds Minutes Resource Use Low High Size Lightweight Heavy (GBs) Ideal For Modern ham tools, APRS bots, SDR apps Legacy systems, OS testing Portability High Moderate Ham Radio Use Cases for Docker

Here’s how Docker fits into amateur radio workflows:

  • Run an APRS iGate with Direwolf and YAAC in isolated containers.
  • Deploy SDR receivers like rtl_433, OpenWebRX, or CubicSDR as containerized services.
  • Set up a Winlink gateway using Pat + ax25 tools, all in one container.
  • Automate and scale your APRS bot, or APRS gateway using Docker + cron + scripts.

Docker makes it easier to test and share these setups with other hams—just export your Docker Compose file or image.

When to Use Docker, When to Use a VM Use Docker if:
  • You’re building or experimenting with modern ham radio apps
  • You want to deploy quickly and repeatably
  • You’re using Raspberry Pi, VPS, or low-power hardware
  • You’re setting up CI/CD pipelines for your scripts or bots
Use VMs if:
  • You need to run legacy apps (e.g., old Windows logging software)
  • You want to simulate full system environments
  • You’re working on something that could crash your main system
Final Thoughts

Both Docker and VMs are powerful tools that have a place in the modern ham shack. Docker offers speed, portability, and resource-efficiency—making it ideal for deploying SDR setups, APRS bots, or automation scripts. VMs, on the other hand, still shine when you need full system emulation or deeper isolation.

At the end of the day, being a ham means being an experimenter. And tools like Docker just give us more ways to explore, automate, and share our radio projects with the world.

ROAST my design before I end up in the streets

Sat, 05/03/2025 - 23:49

Hey everyone,

I recently launched a small SaaS project and while I’m getting some traffic, the conversion rate is sooo low. I’m trying to figure out if the design is part of the problem — or the problem.

So I’m here humbly asking you to roast it, and have no mercy. I want the truth — whether it looks bad, feels off, has bad UX, whatever. I can take it. I’d much rather be hurt now than burn through my life savings, sustaining an ugly saas.

Here’s the link: Tablextract

Let me know what’s confusing, ugly, inconsistent, slow, or just straight-up annoying. Also down for suggestions if you feel like being generous.

Thanks in advance!

Am I the only one that dislikes Wireframe CC?

Sat, 05/03/2025 - 18:52

I'm new to web design, so take this with a grain of salt. I've been browsing around for good, easy wireframe websites so I can finally stop using PowerPoint to do them. I tried the 7 day free trial for Wireframe CC and found it infuriating. Perhaps there's worse out there and I'm complaining about a decent wireframe software and I don't even know how good I have it. But my experience with wireframe was really clunky. Often when I added text boxes, it would then forget they were there and I could no longer select, edit or delete them. This happened to me on my college computer and my personal laptop, so I can't be the only one experiencing this. Has anyone else had this experience? I'm glad for the free trial because now I know I will never be subscribing for this product. Do yous have other recs, potentially for a free software I can use?

Why is Amazon's website design so ugly?

Sat, 05/03/2025 - 15:13

I can't be the only one seeing it. The all white pages, strange font choices, horrendous product image compression, terrible layout, cluttered webpage in general. Even the text looks awful on the page.

Why hasn't Amazon revamped their design? Is it ugly on purpose? I mean compared so sites like YouTube, the difference in quality is striking.

Is it a best practice to remove and re-require Drush before a major upgrade?

Thu, 01/16/2025 - 15:48

At all times that I have done a minor upgrade, only once have I needed to remove and re-require Drush itself to succeed.

But when it comes to major upgrades, is it a best practice from whatever reason to remove and re-require Drush before a major upgrade?

How can I filter a view by multiple node IDs from a vertical list?

Thu, 01/16/2025 - 15:48

I have a long vertical list of node IDs that I wish a certain view will never show.

512 6 90 71 1501

If I filter these node IDs by a Filter Criteria with a regular expression then I am being "prompted" to do that in a long horizontal line and that's hard to maintain; my actual list is much larger than five values and is more like fifty values.

How can I filter a view by multiple node IDs from a vertical list?

Linux at work

Thu, 01/16/2025 - 13:38

Hi all,

At my home, I use Arch with Hyprland and I couldn't be happier right now. I love the tiling, I love the animations, I love the plugins, truly an awesome experience.

I recently started a new job where they use Ubuntu 22.04. I haven't really used Ubuntu since I was just starting my Linux journey, and I find it lacking in the customizability department since I'm used to more cutting edge and customizable distros (Arch and NixOS). I do understand that it probably doesn't make since for a corporation to use these distros since they both aren't stable, don't offer LTS, and are unintuitive for most people.

My question is: how can I most closely mirror my home configuration at work? I read that getting Hyprland to work in Ubuntu is a real pain (and will rarely survive an update). So I've been thinking about getting Sway (I used to use i3 and sway a while back so I know the ropes), but I thought maybe I'd ask here if there's a wm that more closely resembles Hyprland that I can use.

Debian DE Performance numbers

Thu, 01/16/2025 - 13:38

***This is Debian12

So just for fun I figure I should post here some information I had gathered through doing some testing with Debian DE on some crappy laptops I have that my kids are using with Moonlight.

Intel N3060<----Sucksssss

All of these numbers are on a fresh install running from EMMC 32gb Flash Chip with 4gb of RAM and just sitting on desktop post install.

These numbers could be useful for people that have access to old machines and want to have an idea of what to expect maybe for homelab use etc.

KDE Plasma- 22.5% Ave CPU 2.3G of Ram used

XFCE-10% Ave CPU 748M of Ram used

Cinnamon-38.5% Ave CPU 1.3G of Ram used

Debian Desktop-17% Ave CPU 1.5G of Ram used

Gnome-20% Ave CPU 1.5G of Ram used

Gnome Classic-27% Ave CPU 1.4G of Ram used

MATE-30% Ave CPU 778M of Ram used

LXDE-10% Ave CPU 319M of Ram used

LXQT-12% Ave CPU 698M of Ram used

****This is not meant to be scientific or overly accurate just some musings. Also of note the machine in question is a HP stream laptop. I am not a Linux expert at all just a Debian fan

Is it just me, or is the gnome ecosystem as a whole suddenly moblie viable?

Thu, 01/16/2025 - 13:38

I've noticed increasingly that the majority of software I'm using has fully baked well designed mobile layouts when scaled to a phone aspect ratio. In addition to this, gnome has been developing its mobile layout for years now. Files, epiphany, gapless, camera, calendar, most apps you really need on a phone are there and in a good state. From what I can tell, you could have an extremely usable mobile linux experience nowadays. (compared to back when the pinephone was a thing)

This might be me, but I feel like I could, at this point, have a complete mobile experience with minimal complaints (that is, other than gnome's atrocious onscreen keyboard)

Custom OS on NVIDIA Project Digits

Thu, 01/16/2025 - 13:38

I plan to buy one or two of those Nvidia Project Digits computers when they come out to add to my lab as AI servers, and I want to put a custom OS on them since I don't want to use Nvidia's DGX OS. Will that be possible? I've heard mixed things about custom OS support.
