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! 🤣

I’m a Tool Builder

I’m a tool builder. I have always been a tool builder. The last 15 years or so of my career have been away from coding as my main task. GenAI has reawakened not just the coder in me, but the tool builder.

Any time I have to solve a problem for the second or third time, I’m already working on how to build a tool, system, procedure to reduce the amount of time it takes. Back in the day I was very fond of code generators. I used them, and I built my own. I built report generators as well.

I’ve been working with “Ralph Loops” - a technique in GenAI to have a complete list of tasks to accomplish and have the ai code, test, fix, test again (until all tests pass) and keep on going down the list. “Write shippable code while you sleep” is the goal. The reality isn’t quite there. The direction is clear - it’s powerful, it’s super productive. But we are less than two months from the first blog post where Geoffrey Huntley introduced the concept he named the Ralph ...

Linux Self Host Up and Running with Cloudflare

Making terrific progress moving off of my hosted vps to a linux box in my home. A looming $350 payment for the next three years was the catalyst for “do I need to pay this, is it time to bring this in house”? I already had the Beelink mini pc, and it’s far faster with more ram than my VPS and the electricity costs are minimal and less than the very reasonable $10/mo of that SSDNODES.COM was charging.

I use docker to partition the vps, and now the Linux Mint machine into “many servers”. When I want to share my work outside my home, that’s where Cloudflare tunnels come in. Exposing ports whether on the vps or on my home router and linux machine is asking for trouble. Cloudflare handles that and more:
Here is the compact definition of what Cloudflare Tunnels provides for your partitioned setup:

$89 Lifetime Lunduke Subs ends this week!

Quick heads up, that the $89 Lifetime Subscription to The Lunduke Journal discount ends… at the end of this week!

Discounting Lifetime Subscriptions by over 70% was an absolute blast. So many of you took advantage of the offer that we’re now up to four Lifetime Subscriber walls at the end of every video. Crazy!

But something that awesome can’t last forever. Which means that, in just a few days, Lifetime Subscriptions will return to their regular price of $300.

With no plans to do another wild discount like that any time soon.

So.

  1. If you haven’t already, snag an $89 (via Bitcoin) or $99 (via Substack or Locals) Lifetime Subscription.

  2. Then let me know if you’d like to be added to the Lifetime Wall of Shame Awesomeness.

My guess is, a the current rate, that 4th Lifetime Wall will be full by Friday.

Bonkers.

And, once again, thank you to each and every subscriber. The Lunduke Journal would not be possible without you.

Lunduke Journal Week In Review - Jan 16th, 2025

Whew! It’s been another wild week for Tech News!

Here’s a crazy stat for ya:

We are currently 16 days into 2026, and The Lunduke Journal has already recorded 19 shows (17 of which have been published on every platform, and 2 others to be published this weekend everywhere… but are already available via the MP4 download page). And that’s with taking New Year’s Day off (and getting the flu this week).

It’s a heck of a lot of Tech News, to be sure.

Lunduke’s Top Stories for the Week

If you only have time to watch a few of shows, I recommend these 3 as being the most interesting (or important… or just… strange) from the last week:

In other words: A pretty gosh-darned crazy week for Linux.

(Those links are to Lunduke.Substack.com, but you can watch all of those shows on any other platform. As always.)

Other Tidbits of Awesomeness

A few other notes on this, most excellent, Friday!

And, with that, I leave you with a screenshot of the MP4 listing of the shows so far in 2026. Bonkers.

Lunduke's Lifetime Subscriber Wall 3 is almost full!

Holy moly.

This afternoon I sat down to update the 3rd Lunduke Journal Lifetime Subscriber wall — adding in all of you who sent in requests over the last week or so.

And, boy howdy, were there a lot of you! So many, in fact, that the 3rd Lifetime Wall only has room for around 6 or 7 more names (depending on the name lengths)! That’s crazy!

If you want to make it onto “The Lunduke Journal Lifetime Subscriber” Wall number 3… send me an email (bryan at lunduke.com) with the way you would like your name to be displayed.

Or, if you’re not already a Lifetime Subscriber, remedy that for $89. (Which, you know, is a pretty gosh darned good value.) … Then send me that email requesting to be added to the wall.

Once Wall 3 is full, we’ll start in on Wall number 4 (that’s nuts). At the current rate, I expect Wall 4 to debut this week.

And, as always, thank you for your support. Whatever kind of subscription you have, it is deeply appreciated. Monthly, Yearly, or Lifetime. All are amazing. You make The Lunduke Journal possible.

You rule.
