Is this present, future, or past timeline?
OpenSSH version:
- 10.0 was released 2025
- 5.0 was released 2008
- 1.2 was released 2005 (on unix)
Extrapolating: OpenSSH 43.2 is millions of years into the future
That doesn't seem right
Upon deeper analysis, you are correct. I was a bit floored by what appeared to be a power curve near the beginning, but after actually plotting, it's a simple linear trend:
Data
Code
curl https://www.openssh.com/releasenotes.html \
| sed -nr '/^<h3><a/s/.*OpenSSH ([0-9.]+).*\(([0-9-]+)\).*/\2\t\1/p' \
| sort \
| sed -r 's|([0-9]+)\.([0-9]+)\.([0-9]+)|\1.\2\3|' \
| column -t -N 'Date,Version' > openssh.dat
head openssh.dat
Which yields:
Date Version
2000-03-05 1.22
2000-03-24 1.23
...
2025-02-18 9.9
2025-04-09 10.0
Fit
Code
gnuplot -p -e '
set xdata time;
set timefmt "%Y-%m-%d";
set xlabel "Date"; set format x "%Y";
set ylabel "Version";
f(x) = a*x + b;
a = 1e-10; b = -100;
fit f(x) "openssh.dat" using 1:2 via a,b;
set label 1 sprintf("Fit: Version = (%.3e * Date) %.3f", a ,b) at graph 0.05,0.95 left;
plot "openssh.dat" using 1:2 with points title "Versions", f(x) with lines title "Fit"
'
Which yields:
Predict
Use Y = (mX) + C, or Version = (9.55651e-09 * Date) -6.75132
Code
Note that Date are Epoch timestamps.
export VERSION="43.2"
date +%Y-%m-%d -d \
@$(
export m="9.55651e-09";
export c="-6.75132";
## Use python for better scientific number handling
python -c "print(($VERSION - $c)/$m)"
)
For OpenSSH version 43.2, the predicted date is:
2135-08-21
So, assuming a linear trend and no cataclysmic events that would pause development for a few thousand years, then it's only 110 years into the future
This is Awesome! How did you learn to do that? I want to learn too
thanks! oh well data formatting, just 15 years of messing around with awk and sed
Data fitting, gnuplot does all the heavy lifting with the modelling, and I always have to look up the syntax because I never remember it haha
Play around and have fun with the code snippets!
I will!
And I'm going to give a look at awk and sed, I didn't know you can do all that stuff with it.
Thanks for sharing :D
in relation to what?
I love you
Where can I buy that bound Actron anthology?
It's an illegal samizdat.
I saw a copy of Language of The Birds on a shelf at Amazon Ho Foods.
Not sure how it got there, but my AI shopping cart drained my account just for looking at the book.
That is a good question.
Who is going to keep the torch we once carried aflame in the future? How will they live? What will their lifes look like?
This is the first one of these I’ve ever seen but I absolutely love it.
This story arc has been great.
Very cool.
