Midori has been around forever, so built on a solid base. I haven't yet used the current version, but I plan to soon.
So I am guessing that is is very stable and reliable, but haven't verified myself yet with the current version.

2026-07-15 18:16:00 UTC

Years ago, I remember using the Midori web browser, usually on lower powered devices. Looks like it has continued to be developed with an interesting Open Source group: Astian. They also have a crypto wallet with Bitcoin Cash supported.

Microsoft Windows Drops Under 60% in Global Desktop OS Share for the First Time in Years
The good news is that the percentage of Windows active usage is going down... the bad news is that it is still over half (fifty percent).

"It is probably most intensely felt in U.S. cities. Nowhere else is poverty treated at greater cost. Nowhere else does the treatment of poverty produce so much dependence, anger, frustration, and further demands. And nowhere else should it be so evident that poverty-once it has become modernized-has become resistant to treatment with dollars alone and requires an institutional revolution."

Physical cash also works well for this (though originally issued by central banks).

I was able to successfully copy a hard disk drive that was failing with bad sectors to another good storage drive using the tool CloneZilla.
I have used CloneZilla for years and it has been very helpful. I use it to make copies and "images" of whole systems. This saves me a lot of time or allows me to do things that I wouldn't otherwise be able to.
The laptop pictured is being "imaged" with CloneZilla and the image is being saved on the external hard drive to the right of the laptop.
CloneZilla is based on Linux and I usually live boot it from a USB drive.

Tomorrow (Wednesday United States time), I will be doing the drawing for my Weekly Computer Giveaway. This week I will be giving away a refurbished ThinkCentre M710q Tiny PC with Linux pre-installed.
I have already shipped a computer out of the United States to a winner... but shipping was expensive.
More people from outside the United States are subscribing to my newsletter. That's a good thing, but I may not be able to ship to some countries or it would just be too expensive to do so.
So I thought of additional prize options if the winner chose not have the computer shipped to them. $50 worth of Bitcoin Cash (BCH) or Monero (XMR).
My goal with the newsletter is to encourage people to use alternatives to BigTech, such as Linux and other less well known operating systems. To use older hardware, preferably PC hardware. And to have fun with computing.
But I also want to promote the CypherPunk ideas of encryption and Digital Cash. I think the two can go together.
For a chance to win a computer every week (or $50 worth of Bitcoin Cash or Monero), just be a subscriber of my email newsletter. To find out if you won, all you have to do is read the email and check to see if you are the winner and reply to claim.

When using Linux on your own computer, or a server, a good skill to learn is scripting with the Bash Shell.
I've known the basics for years, but have recently been pushing myself to write more useful and slightly more complicated scripts in Bash.
Commenting code is very helpful, both in writing the code as comments can give a structure that is then filled in with functional code, and also later when reading the script to review or make adjustments.
Here's a good article (not by me) on how to use comments in Bash Scripts:

The promise of Bitcoin Cash is exciting. But people actually have to use it for that promise to become a reality.
Thanks for contributing in your way!

2026-06-21 16:24:00 UTC

I do not expect Bitcoin Cash or Monero to ever surpass Bitcoin (BTC) all time high price (over $100K) but both already surpass BTC in every day on-chain usage (purchases, private non-investment payments).
Just like physical money historically had three major players: gold, silver copper - crypto-currency is likely to have a top 5 where people choose their top three out of those for their desired purposes. My prediction is that Bitcoin Cash and Monero are likely to be in that top five.

2026-06-21 15:53:49 UTC

"Bitcoin has no cash flow, no dividends, no yield, no earnings reports, and no balance sheet. The only thing resembling a return is the price splashed across screens to fuel the cult's chants, which means the only strategy they can sell you is to hold forever and believe harder. This reality is compounded by the risk of a 75% sudden crash, documented three times in Bitcoin's history -let me repeat that: three times in Bitcoin's history! In those moments, there were no stop-losses, no circuit breakers, and deposit insurance was non-existent. There was only diamond hands and the promise that the line would go back up, and they are still running this circus. Here is the truth they never told Satoshi holders: the HODL strategy made mathematical sense before 2017. The market cap was tiny, and the asymmetry was real. A 10x, 50x, or 100x gain was arithmetically possible without requiring Bitcoin to surpass the GDP of the United States."
-- quote from ProfAnarch post
Interesting to note that the hard fork that became known as Bitcoin Cash (BCH) happened on August 1, 2017

I wasn't aware of the 'bc' program before writing this script. It is not needed for the script to do its job, but used to calculate the amount of disk space freed in MegaBytes (MB). It wasn't installed on the server I used this one, so had to install 'bc' using the package manager. So 'bc' ends up being an optional dependency to this script.

I got the cleanup script that I was writing working as I wanted it to. Implemented it on a server and scheduled it to run every day at a certain time.
The screenshot does not show the whole script, just the end part. It removes some specific things to clear up disk space, calculates how much disk space was freed, then write an entry to a log file with that information.
I learned a few more things. Putting into practice what I learn.

from THE CYPHERNOMICON:
4.5.3. "The admonition, "Cypherpunks write code," should be taken
metaphorically. I think "to write code" means to take
unilateral effective action as an individual. That may mean
writing actual code, but it could also mean dumpster diving
at Mycrotronx and anonymously releasing the recovered
information. It could also mean creating an offshore digital
bank. Don't get too literal on us here. What is important
is that Cypherpunks take personal responsibility for
empowering themselves against threats to privacy." [Sandy
Sandfort, 1994-07-08]
https://cdn.nakamotoinstitute.org/docs/cyphernomicon.txt
In my opinion, writing actual computer code is important. But if you can't write code, taking other action is also vital.
