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

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

[–] tetris11@lemmy.ml 2 points 3 weeks ago* (last edited 3 weeks ago) (1 children)

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!

[–] stan_stanminson@lemmy.dbzer0.com 2 points 3 weeks ago (1 children)

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

I seem to be on a gnuplot bender at the moment, but maybe you will enjoy this too!

Where can I buy that bound Actron anthology?

[–] pmjv@lemmy.sdf.org 19 points 3 weeks ago

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?

[–] buttnugget@lemmy.world 5 points 3 weeks ago

This is the first one of these I’ve ever seen but I absolutely love it.

[–] jawa22@lemmy.blahaj.zone 5 points 3 weeks ago

This story arc has been great.
