The Unix Crash of 2036

First of all, do not cross-post. I have deleted your second post.
The information in that link you posted is mostly garbage. I really shouldn't dignify stupidity like that with a response. But I guess that's the only way to fight ignorance.
The 5100 was wimpy computer even in it's own day. It cannot be used to correct a modern os. It can't even store a copy of a modern os.
The alleged time traveller
states that he travelled back from 2036 to correct a unix problem that will occur in 2038. There are two very well known problems that will need a solution before then, but only one can be called a unix problem and it is nearly solved.
Jan 19, 2036 is 2^31 seconds after the unix epoch and it will overflow a signed 32 bit integer. We are starting to move to 64 bit systems now. Assuming that we retire 32 bit systems by 2038, the problem is solved. HP has stated that this is their solution for HP-UX.
A second problem will arise at the same time with the NTP protocol. The NTP protocol will need to be extended in some way prior to 2036. Admittedly we don't have a definite solution yet, but their have been proposals. I'm confident that we'll settle on a solution by then.
This problem is trivial conpared to y2k. And that was a very minor problem.
But if we fumble somehow, the solution will not involve returning to 1975 to snag an old IBM 5100.
And even if it did, we could not get our computer clocks to work, but we can build a time machine? Whoa....

uligo(6) Games Manual uligo(6) NAME
uligo - tsumego (go problems) practice tool SYNOPSIS
uligo DESCRIPTION
To get stronger at go, it is essential to develop one's reading ability. That is why professionals recommend to study life and death or tesuji problems. uliGo is a program that allows you to do that: basically, the computer displays a problem, and asks for the answer. You enter the first move, the computer responds, and so on until you reach the final solution or enter a wrong move. USAGE
The basic operation of uliGo is simple. Click the right arrow to view a problem, and then click where you think the right answer is. The Documentation item in the Help menu contains the full documentation for uliGo, such as configuring the timer or the order the tsumego are displayed in. By default, problems are presented in random order, with the colors and orientation of the problem randomly chosen. FILES
~/.uligo This directory stores information about how many problems you've solved, and SGF files you've downloaded yourself. AUTHOR
Ulrich Goertz <uligo@g0ertz.de> is the author of uliGo. Joe Wreschnig <piman@debian.org> wrote this manual page for the Debian operating system, but it may be used by others. SEE ALSO
The uliGo website at http://www.u-go.net/uligo/ contains more (unclearly licensed) problems sets that cannot be included with the Debian package. April 25th, 2003 uligo(6)
