Offline Computing – Preparing For Uncertain Times

Offline Computing – Preparing For Uncertain Times

Offline Computing

This is an article I write every couple of years. The more this world descends into chaos, the more I think to it wise to update the content. I’m not a Doomsday guy but it is easy to imagine a scenario where we are without things like electricity, cellular networks, and internet for extended periods of time. Having a computer capable of offline computing and receiving communications could be life saving or at the least life enhancing.

The time to prepare this computer is now because if you wake up to massive outages it will be too late. And you should make a habit of keeping it up to date and adding content to it as required.

I’m not going full prepper on you here. But I am trying to help you get past a catastrophic event such as a hurricane, or other massive weather event that could cut you off for an extended period of time. It could be as simple as the power lines are down, or as extensive as someone popped an EMP off over the Untied States.

Additionally, while I tell you I am not a hardcore prepper, I am a believer in Bible Prophecy. If you aren’t, that is cool. I am. And bits and pieces of it are unfolding now as we speak. Here is an example ripped from recent headlines. The US and Iran are tangled up. One key sticking point is that Israel withdraw all troops from Lebanon. In Genesis God promised Abram land and defined its boundaries. It is much larger than the current state of Israel. One border is the Euphrates River and you certainly have to work your way through Lebanon to get there. Currently Israel is about 30 km into Lebanon at the Litani River and wanting to move deeper north to expand their buffer zone.

GhostBSD – A Linux Alternative

GhostBSD – A Linux Alternative

I’ve always loved trying various operating systems. So it is with GhostBSD. Most of the time I put these OS’s on a virtual machine which is fun, but you can’t take a virtual machine with you.

I have a whole bunch of laptops around here and one that I routinely try with various Linux distributions. Once upon a time I had installed FreeBSD on something and was proud as punch when it worked. Not too long ago I tried it again and borked the Desktop GUI installation somehow or another and then bounced directly to KDE Neon. Ultimately, I decided to do another BSD variant and GhostBSD comes with a Desktop Environment. In fact just like Linux you can configure a bunch of different environments for it. I got the version with MATE Desktop.

GhostBSD describes themselves are being “Unix like”. While being based on FreeBSD, you seldom see the word Unix pop up. FreeBSD is an open source derivative of AT&T’s Unix which was not open source. A bit confusing, but let’s just call it an operating system and move on.

Zimaboard 2 – Intel N150 Single Board Computer

Zimaboard 2 – Intel N150 Single Board Computer

Zimaboard 2

I’ve been eyeballing this Zimaboard 2, Intel N150 based single board computer since it hit the scene.

Suffice to say though I am a Raspberry Pi Geek, through and through. I have a server rack with 8 of them. Then I have a mini rack with 3 more of them.

Additionally, I have a couple of those N150 GMKtec mini computers. I need another single board computer like I need another hole in my head. Which of course means that I broke down and got the Zimaboard 2 1664 version.

Someone finally found the middle space between a single board computer and a mini-PC. Kudos to IceWhale.”

Mobile Pixels Duex Plus DS Review

Mobile Pixels Duex Plus DS Review

Mobile Pixels Duex Plus DS

I was contacted recently by the CEO of Mobile Pixels to review the Mobile Pixels Duex Plus DS portable monitor ($169.99 on Amazon)

Additionally, I was provided the 13.3″ screen since I indicated I had a 13″ MacBookAir. Man, I sure wish that I had one of these during my working years. This is great for blogging.

I’m able to view my web design portal in my browser on one screen while reading the product manual and various other technical documents and also reviews on the other screen. I’m one of those weirdos that has 10 open tabs in a browser at any given time.

This really does improve my workflow. I simply cannot deny that. Also, the screen can be set as a main display, extended display, or mirrored display. I personally like the extended display the most.

Werewolf VFLEX Adapter Review

Werewolf VFLEX Adapter Review

Werewolf VFLEX Adapter

In a world full of power bricks along comes something that provides power with far less clutter. If you are currently using a bench power supply to provide power to your gizmos the Werewolf VFLEX Adapter system may be for you. I recently bought several items from them and hope to share what I’ve learned.

But first let me give you a real world example. I’m a photography nerd. In the mid-2000’s I bought a device called a Nikon Coolwalker. It was designed for the days of low capacity Compact Flash cards. Fill up your card on a shoot and then dump the photos into the Coolwalker. Format your card. Shoot. Repeat.

That device had some crazy battery in it called the Nikon EN-EL6. It was only made for the Coolwalker. And of course after 20 years that battery is deader than dead. And there are no 3rd party EL6’s available even today.

I needed to feed it around 6 volts to start it. At first I did it with a bench power supply and some barrel connectors and bread board wires. It was ugly, messy, and probably dangerous (to the Coolwalker). Then I saw a review video from Jeff Geerling on his “Level 2 Jeff” YouTube channel showcasing the VFLEX system. If you don’t know who Jeff is, it is worth your time to check out his channel. He’s probably one of the world’s best Raspberry Pi and Kubernetes geeks and he isn’t constrained by those two things at all. His network timing and atomic clock and GPS synchronization videos are awesome to me. Especially, since I play with GPS modules and Pulses Per Second (PPS) while getting time sync from GPS satellites.

Best Gear Of 2025

Best Gear Of 2025

And yet another trip around the sun is near to completion. What was the Best Gear of 2025? These are a few of my favorites. Let me know in the comments what your selection for the best gear of the passing year is.

Computer Hardware

I should have added this to the bottom as a grand finale, but it also fits nicely at the top. For 2025 the Beelink Me Mini is one of my top picks for Gear Of The Year.

It is a high capacity NAS that is SILENT and uses NVME M.2 SSD drives for data storage. While the Beelink Me Mini is inexpensive, sadly memory prices have exploded. I got mine just in time it seems.

Equipped with 16 GB of built in RAM and four 4TB drives nets you about 12TB of storage in a RAIDZ1 configuration. Even better is that you can install TrueNAS on this device. This is replacing my very noisy QNAP NAS appliance.

Syncthing

I’m going back to my roots here with Syncthing. My tech blog started as a way for me to record my projects so that when they blew up I could reconstruct them.

When you crack that code and then six months later you realize you forgot that code you have to start back at square one. Here’s my back story.

I have a QNAP server and use Qsync Client to back up my important files to that NAS. I just deployed another NAS (Beelink Me Mini with TrueNAS) recently. Additionally, I thought that Qsync Client software could be used to back up to TWO NAS devices. It couldn’t. Well technically it can but not from the same computer. That won’t do.

So I hit the Google and one name for synchronization software kept popping up. Syncthing. So I installed it on my Mac which was no problem at all. Then I went to set it up on TrueNAS. Not as easy. Read on for more fun…..

Beelink ME Mini NAS Review

Beelink ME Mini NAS Review

Beelink Me Mini

This may be one of the best pieces of tech I have seen come down the pike in some time. Having a Network Attached Storage (NAS) device has become fairly standard in a lot of households and is darn near required in the office or business space. Enter the Beelink Me Mini NAS ($259 for the 16GB version) device.

This is a unique device based on the Intel Twin Lake N150 chip. The N150 is a 4 core, 4 thread chip with a max turbo boost speed of 3.6 GHz. It also sips power at about 6 watts.

Storage consists of a 64GB eMMC onboard and 6 NVME M.2 slots for a max capacity of 24 TB. The downside though is that 6 – 4TB NVME drives are EXPENSIVE. Also due to limitations on the PCI Express Lanes (9 total) it is possible that populating all six drive locations MIGHT cause some power or bandwidth issues. If possible, low power NVME drives could be utilized.

PCBWay Printed Circuit Board Prototype Review

PCBWay Printed Circuit Board Prototype Review

pcbway printed circuit board

If you stumble across my site chances are you were looking for something technical. And if you were looking for something technical you may have had a need to put that technical idea onto a printed circuit board. This is where PCBWay can help

There are just so many times that I have used the venerable old breadboard to lay out my projects. And then sometimes those projects just stay like that.

pcbway printed circuit board

So suppose you’d like to translate that simple circuit into something a lot more polished. Why not sketch out your idea and make a proper printed circuit board (PCB)?

There are a ton of PCB software design solutions out there. For years I have used a program called “Fritzing”. But PCBWay can help with prototype design as well.

Canon Powershot A640 Review

Canon Powershot A640 Review

Canon Powershot A640

You might be asking yourself why I’m reviewing the Canon Powershot A640 which was released to consumers in 2006. By my estimation that makes it nearly 20 years old.

And you really might be wondering why I’m writing about it 19 years after I bought mine.

By today’s standards it has features that a lot of cameras today should have at the same price point.

I am not referring to sensor size or megapixels although it has a respectable 1 1/8″ CCD sensor with 10 Mega Pixels. And DPReview.com gave it a pretty decent review in late 2006.
