"There are two ways of constructing a software design. One way is to
make it so simple that there are obviously no deficiencies. And the other
way is to make it so complicated that there are no obvious deficiencies."

Perhaps this is a testament to SPARK/Ada's focus on secure programming?
Ada jumps to number 11 from 25

I gained new respect for the Pascal family of languages after I started
working with Delphi and later teaching introduction to programming. Much
of Ada is influenced by Pascal.

Back in the day, we used to love to hate Microsoft. I imagine that still
may be true with some.
Did you know that Dot net is open source / free software?
https://dotnet.microsoft.com/en-us/platform/open-source
I am thinking that next meeting, we do C# on Fedora.
I was just working through the following tutorial.

I don't know how many of you ever went to OSCON, yet I have fond memories
of attending it both in 2010 and 2014. I searched online and it seems
that Covid put the nail in the coffin for OSCON and stopped it for good.

What a bummer deal.
I remember it was 1997 that I believe the first PERL conference started
and it eventually turned into OSCON. I am going to start sing "Glory
Days" by Bruce Springsteen.
On a side note, I spoke with Kyle Rankin, who has presented at various
conferences, and he presented at SCALE (Southern California Area Linux
Expo). He said that they have a good in person conference.

Hello Everyone,
We will have another social meeting at Kupros, June 17, 6:30pm
https://www.saclug.org/articles/2025/june-2025.html
We will likely be at a large table upstairs. I will put a paper penguin
in one of the holders on the table. If you are not sure where to look,
please email me beforehand we can coordinate.
See you there.

I just spent about 4 hours setting up a pubkey ssh authentication. The problem was that my sshd was no longer accepting pubkeys generated on my remote system using rsa or dsa. I finally tried an ecdsa and everything worked.
Running ssh -v, -vv, and -vvv didn't really help because it just fails silently. You have to figure out what a message offering the private key as the public key is important and then make a guess that something bad happened there because the authentication process continues. There are other messages earlier in the chain that make is seem like it can't find files.
I spent a lot of time confirming file permissions. My books didn't agree with a lot of what I found on line. Which is right? A lot of thrashing around there.
Granted, I'm retired and doing all this for fun. Well sort of. I do like to use a lot of this stuff and I find it helpful. But when something I, "know how to do" and is suppose to make my life easier and simpler, takes a lot of time, I need to reevaluate my approach.
Your average person just buys a 3rd party tunneling/VPN service and goes from there. Which is great if you are running Windows.
I think it is time for me to consider my approach and how I am spending my time and money. This just isn't sustainable.
I'm not saying things were better "back in the day." There was definitely a time when it was hard to do a lot of things. We had "install fest" for example. Documentation was nonexistant. Then, it seemed like for awhile, things were pretty good. Things just worked and there was documentation and you could get information.
I think there was a definite peak in usability. Or is it just me?
Maybe I'll start by figuring out a minimum set of functionality that I need and take a fresh approach from there.

It is a simple thing to make things complex,
a complex thing to make things simple.
LibXml2 seems to be one of those un glorious packages to maintain. I saw
the following posted by a project maintainer.
https://gitlab.gnome.org/GNOME/libxml2/-/issues/913
His observations on disclosing security vulnerabilities seem to be
interesting.
