Véletlen Indítású Hegymászó Algoritmus
szorgosan mászik
sok vakond a sün hátán
még magasabbra
A* keresés
utam tanított,
de álmom mutatja meg
merre van tovább
Szimulált lehűtés
egyre inkább vágyom
a Nap közelébe
ahogy köszönt be a Tél

Out of memory.
We wish to hold everything!
But still we cannot.
Rather than beep
Or a rude error message:
These words: "File Not Found".
Errors have occurred.
We won't tell you where or why -
Lazy programmers!
Chaos reigns within.
Reflect, repent, and reboot
Order will return.
For a new PC,
Center of my universe,
I abandon all.
The code was willing!
It considered your request,
But the chips were weak.
Everything is gone.
Your life's work has been destroyed.
Squeeze trigger? (yes/no)
A file that big?
It might be very useful.
But now it is gone.
No keyboard present
Hit F1 to continue
Zen engineering?
Website has been moved
We'd tell you where, but then we'd
Have to delete you.
The web site you seek
Cannot be located but
Countless more exist.
Aborted effort:
Close all that you have worked on.
You ask way too much.
Windows XP crashed.
I am the blue screen of death.
No one hears your screams.
Yesterday it worked.
Today it is not working.
Windows is like that.
Printer not ready.
Could be a fatal error.
Have a pen handy?
First snow, then silence.
This thousand dollar screen dies
So beautifully.
With searching comes loss
And the presence of absence:
"My novel" not found.
The Tao that is seen
Is not the true Tao, until
You bring fresh toner.
Logon incorrect!
Only perfect spellers may
Enter this system!
Stay the patient course.
Of little worth is your ire.
The network is down.
A crash reduces
Your expensive computer
To a simple stone.
Three things are certain:
Death, taxes, and lost data.
Guess which has occurred.
Seeing my great fault
Through darkening blue windows
I begin again.
You step in the stream,
But the water has moved on.
This page is not here.
Out of memory.
We wish to hold the whole sky,
But we never will.
10,000 Things
How long do any persist?
Explorer is gone.
Server: poor response
Not quick enough for browser
Time out, plum blossom.
This site uses frames
And yet your browser does not.
One of these will change.
Having been erased,
The document you're seeking
Must now be retyped.
Serious error.
All shortcuts have disappeared.
Screen. Mind. Both are blank.

Egy fájl, ami oly nagy?
Talán hasznos volt.
De már a múlté.
A weblap mit keresel
Nem található, de
Végtelen sok másik létezik.
