Digital Prepping, Part 1 - Off-Line Websites & Maps
The first step in making your computer usable when the Internet goes away. Because it will.

This is Part 1 in a series of articles on “Digital Prepping” — preparing your computers and smartphones for the possibility of any number of events… which could leave you without Internet or power for an extended period of time.

The Internet is an amazing tool, to be sure — an always connected network which we can use to look up nearly any piece of information we might think of.

Historical tidbits, recipes, maps, technical engineering details, how-to’s, song lyrics… you name it.

But what happens… when that “always connected network”… is no longer always connected?

What if, for whatever reason, you are left without Internet access for an hour? A day? A month? Or, dare I even say it, what if the Internet is simply… gone forever?

These are not far-fetched notions.

  • The Internet has only existed for a short period of time — there is no reason to believe it will continue to exist indefinitely.

  • There are regular Internet outages all across the world, with some impacting large areas.

  • And, let’s face it, the Internet infrastructure is darned fragile — with huge numbers of critical points of failure.

Plus… There are areas you may travel to where you simply will not have Internet access. Or, heck, you might not want Internet access for some reason.

In other words: How do you get access to all of that information… when you cannot access the Internet?

Luckily… it’s pretty darned easy. You’ll just need to plan ahead a little bit.

Off-Line Websites

The first — and possibly the easiest — thing you can do is to grab an “Off-Line Web Browser”. Which is exactly what it sounds like: an application that lets you use websites — which you have pre-downloaded — when you have no Internet connection.

There are multiple options available but, for now, I recommend starting with Kiwix. Which, as luck would have it, is available for nearly every major computing platform you can think of (Windows, Mac, Linux, Android, and iOS).

Seriously. You can run Kiwix just about anywhere.

Kiwix works by loading a website archive file format known as a ZIM file — which, essentially, takes a whole website… and sticks it into a single, searchable file for your use when Off-Line.

Once installed, you can then proceed to download any of a number of website archives that have been pre-created — on a huge range of topics. Including archives of Stack Exchange Q&A’s, Wikipedia, Project Gutenberg, cooking & prepping resources, and so much more.

Those .ZIM website archives can be downloaded both from the website, as well as directly from within the Kiwix application, itself. Extremely easy to use, no account necessary, and it runs almost anywhere.

Once downloaded, you can use Kiwix almost like any normal web browser. Except it’s not connected to the Internet.

Depending on how many websites you’ll want full archives of, this can take up quite a large amount of space. The full archive of Wikipedia, for example, is 89 GB in size (luckily they’ve also broken that down into categories if there are only a few topics that interest you).

Want all of Wikipedia, Stack Overflow, Project Gutenberg (which gives you over 60,000 eBooks, including a huge number of classics), and the full archive of wikiHow (because instructional articles are handy)? You’re going to need several hundred GB of storage ready (and, hopefully, a pretty fast Internet connection to grab them all).

Luckily, once downloaded, those .ZIM archives can be backed up, copied around, and re-used on any device.

Off-Line Maps

There was a time when all maps were “Off-Line”. They came on paper, and every car had a collection of them in the glove compartment. And everyone had a road atlas (at least one covering the area they lived).

Nowadays? Almost everyone has become reliant on services like Google Maps to find their way around.

Loose access to the Internet? This can become a big problem in a hurry.

Luckily we have solutions.

The first, and most simple, solution is to use the “Off-Line Maps” feature of Google Maps. This allows you to download a large portion of the location data for an area that you select. You will then be able to use Google Maps (somewhat) regularly for that region.

This is handy. And, if you use Google Maps, I highly recommend doing this for at least the area where you live. It truly does work pretty well.

However: There are some serious downsides to this mechanism.

  • Your “Off-Line” map is not going to be available to you on all of your computers and smartphones.

  • It is only going to function as long as Google’s software allows it to function. And, since that software is all closed (and typically reliant on an Internet connection), we have no idea how long that will truly be.

  • It assumes you can (or want to) use Google Maps.

Which means: You’re going to want another solution as well.

My personal recommendation: OpenStreetMap.

OpenStreetMap is a free — volunteer built — map database which, in my experience, is extraordinarily complete. You will, on occasion, find gaps in information… but usually only for the most remote areas.

There are a large number of applications, for a number of platforms, that can utilize OpenStreetMap data while Off-Line. But, for my money, the best available is Marble.

Marble is available for Linux, Windows, Mac, and Android… and has an absolutely huge number of features. Including the ability to download sections of a map, or download entire map databases — including modern maps, satellite views, and a wide range of historical maps and globes dating back hundreds of years.

All of this makes Marble not only an excellent choice for modern mapping and driving/walking direction needs… but also for educational and historical purposes.

Note: If you have trouble running Marble on recent versions of Android, there are several OpenStreetMap applications available for mobile platforms (including OsmAnd).

This is just scratching the surface

As you begin your “Digital Prepping” journey, you’re going to quickly realize just how much of your day-to-day computing is utterly reliant on an active Internet connection (or, at the very least, an occasional connection).

Music, language translations, software installations and updating, operating system setup, communication… the list goes on-and-on.

What we’ve done here, today, is the first step towards preparing yourself for a complete and total loss of Internet connectivity — an eventuality that is all but certain to occur (even if just for a short period).

As we continue through this series of articles, we will also be touching on some other aspects of “Digital Prepping” that are a bit more… let’s just say… intense.

  • Computing when there is no electrical power grid.

  • Creating your own “Mini Internet”.

  • Short, medium, and long range data transmission.

  • Preparing for EMPs (electromagnetic pulse), floods, fires, and other physical threats to computers and data.

  • Effective and safe backups of critical data on physical media.

Your Homework for Part 1

It’s one thing to know these options are available for having access to information Off-Line… it’s another to put it into practice.

With that in mind… I’ve got some homework for you. Nothing difficult… should take no more than a few minutes, at most. But, when you’re done, you’ll have taken your first steps towards becoming a true Digital Prepper.

  1. Install both Marble and Kiwix on one device. The links are above.

  2. Launch Kiwix and download one website archive that interests you.

  3. Launch Marble, select “Open Street Map”, zoom in to the town you live. Select the File Menu, and click “Download Region” to make an Off-Line copy of that map area.

(If you don't want to -- or can't -- use Marble... no problem.  Simply choose a different Mapping alternative from above.)

Shazam! You now have your local area mapped for when the Internet goes down… and you have something to read!

See you in Part 2 of “Digital Prepping”… where we will prepare your Operating System for being completely Off-Line (including installation, drivers, updates, and installing new software).

The futility of Ad-Blockers

Ads are filling the entirety of the Web -- websites, podcasts, YouTube videos, etc. -- at an increasing rate. Prices for those ad placements are plummeting. Consumers are desperate to use ad-blockers to make the web palatable. Google (and others) are desperate to break and block ad-blockers. All of which results in... more ads and lower pay for creators.

It's a fascinatingly annoying cycle. And there's only one viable way out of it.

openSUSE says "No Lunduke allowed!"

Those in power with openSUSE make it clear they will not allow me anywhere near anything related to the openSUSE project. Ever. For any reason.

Well, that settles that, then! Guess I won't be contributing to openSUSE! 🤣

And now for the big picture!

You guys will love this: Ford Brings back Humans and AI is sub par.

This is an adoption problem. Companies introduce AI and then reduce staff BEFORE the AI proves itself. Not very smart. Lots of companies are going through this.

Story: So it turns out that a computer algorithm cannot teach itself what decades of hands-on, grease-under-the-fingernails human experience already knows.
Ford executives just peeled back the curtain on a massive strategic pivot. The automaker frantically brought back 350 veteran technical specialists to fix a lingering quality and recall crisis that their shiny AI systems simply could not solve.
Some of these seasoned experts were former Ford employees who had previously retired or moved on. Others were specialists poached back from various supplier companies. Either way, Ford leadership looked at their internal metrics and realized they needed the old guard back in the room.
So what exactly is going on?
Ford's Chief Operating Officer Kumar Galhotra ...

I’m a Go Developer!

Ok, I’m a product owner, solutions architect, and agentic AI practitioner directing AI to write my current project in Go. Why? It’s a server app that I want to run on my Linux box as a shared service and on any of my other computers as a local service. I wanted a single executable file, a single sqlite data file and a single config file as “the whole thing”. Python is out. I could have done it in Rust, but why? The lead AI teammate playing the role of architect recommended Go, so I went with Go.

What’s the app? I wanted a Jira style ticketing system - but not Jira, not bloated like Jira. It’s really designed for agents. I want to have autonomous agents that wake up and can find new instructions for work they can do. I want one agent to spawn sub agents and give them work. Of course I want to see status in a dashboard, but mostly this is to facilitate agent communication.

I did a review of what’s out there and did the buy/build consideration and decided to...

Emacs & Vim Lunduke Journal Lifetime Walls Are Here!

TL;DR

The Commodore 64 Wall is full, and the Emacs and Vim Walls make their appearance! Lifetime Subscriptions continue to be discounted all June long for those who want to get on the Walls!

Emacs & Vim Lifetime Walls!

Lifetime Subscribers to The Lunduke Journal filled up the “Commodore 64” Wall in just 10 days! Awesome.

And with the “Ubuntu 4.10” and “BeOS R5” Walls almost full of names as well (just a few spots left on each), it’s time for some new Walls for Lifetime Subscribes to put their signatures on!

This time, let’s have a bit of a friendly competition: Vim vs Emacs.

 

Both Walls — “Vim” & “Emacs” — appeared at the exact same time.

Let’s see which one gets full first. To keep it fair, I’ll cap both off at the exact same number of names.

When they’re full, I’ll included a statement of “Filled in X Days/Hours” next to each on Lunduke.com so everybody knows which one was more popular.

In fact, maybe I’ll add exactly that sort of “Filled in X Days” label for all of the existing Retro Computer Lifetime Walls. Just for fun.

Will Emacs or Vim win? I have a guess. We’ll find out!

Support The Lunduke Journal & Get on The Wall

Want to take part (and support The Lunduke Journal in the process)?

  1. Go to Lunduke.com, scroll down to the bottom and see which Walls are currently listed as still having space available for more names.

  2. Then scroll down on this page and grab a Lifetime Subscription (if you don’t already have one) and email “bryan at lunduke.com” with which Wall you would prefer to be on.

Note: One Lifetime Subscription = One Listing on One Wall. These fill up insanely fast, so I have to put this limit in place. You are more than welcome to get multiple Lifetime Subscriptions if you want to be on multiple Walls.

Your name will then appear on a Wall… on both Lunduke.com & during the end of new Lunduke Journal shows.

Lunduke's Week in Tech : June 21 - June 27, 2026

Lunduke’s Thoughts of The Week

This week, like most weeks, was an absolute rollercoaster in the world of Computer News (tm). Organizations banning co-founders. Corporations taking away access to media you’ve purchased. Wild stuff. See all of that below.

But let’s get off the crazy Tech News Rollercoaster for a moment, and talk about something truly inspiring. And, importantly, stupidly fun.

I would like to point you towards FujiNet.

I’ve talked about FujiNet before but, if you haven’t looked at it recently, you owe it to yourself.

It is, in part, a WiFi adapter for a wide array of 8-bit computers. Atari, Tandy Color Computer, Apple II, and DOS. But that really doesn’t do these sweet little devices justice.

Because the FujiNet adapters handle all of the internet protocols on-device, they allow such feats of technical wizardry as… using an Apple II to connect to a modern SSH server running on a Linux host. Wild.

The team behind these amazing little gizmos have been working on two new things lately, both of which brought a tremendous smile to my face.

The first is a series of FujiNet programming manuals, and user manuals, for each supported retro computer platform. What’s more… they took the extra effort of making the PDF manuals use the classic styles of each platform’s own manual.

For example: The Apple II FujiNet “Getting Started” manual is designed to look like the old Apple IIc manual. Same with the Coleco Adam manual.

It’s a little touch… but it really tells you a lot about the love these guys have for these classic machines.

The second thing they’ve been building, is a set of Android emulators, for those retro computing platforms, with built-in emulation of the FujiNet itself. So you can, for example, have a “FujiNet” enabled CoCo… online. Emulated on your Android phone/tablet.

Because the team has taken the time to build online multiplayer games — with versions for each computer — you could use an Android phone to emulate a CoCo and play a multiplayer game with someone on an Atari Lynx.

If you’re interested in this retro computing magic, I recommend following Thomas Cherryhomes on X. He regularly posts goodies related to FujiNet. And, honestly, it’s just too much fun for words.

Biggest Tech Stories - June 14 - June 20, 2026

Here are the major stories from the last week, with direct links to X and Substack.

See Lunduke.com for all other platforms (Rumble, RSS Audio Podcast, etc.).

  • Which Operating Systems Are Refusing to Do Age Verification? (X, Substack)

  • Paid Minimalist Brave Browser? Yes, Please! (X, Substack)

  • Wikipedia Bans Wikipedia Co-Founder For Saying Wikipedia Should be Neutral (X, Substack)

Three Retro Lifetime Walls Open

Which means there are 3 Walls currently available to put your signature on:

  • Commodore 64 : Only a few spots left

  • BeOS R5 : 1/2 full

  • Ubuntu 4.10 : 2/3rds full

 

Take your pick. There’s no wrong answer here. Three classic Operating Systems.

Support The Lunduke Journal & Get on The Wall

Grabbing a Lifetime Subscription to The Lunduke Journal — and getting your name on one of the Retro Computer Lifetime Subscriber Walls — is the best way to show your support for truly independent Tech Journalism.

  1. Grab a Lifetime Subscription (1 name on 1 Wall per Lifetime Subscription), scroll down for the links.

  2. Then Email Lunduke (“[email protected]”) with which Retro Computer Wall you would like to appear on (and what name you would like to use).

Your name will then appear on a Wall… on both Lunduke.com & during the end of Lunduke Journal shows.

Note: These fill up crazy fast. We’re talking days, not weeks. First come, first served. If you want to get on a specific Wall, don’t dilly dally.
