KVCD in Linux

What is the reference to year 2038 about?
Just wondering, thanks |

Since the time is coded on 32 bits, you can have only 2^32 seconds before to have a general reset of all time based programs ! And the lethal date is in 2038 (you can count :-)) Thats will be a HUGE bug, far larger than the Year 2K one. |
ah Thanks :wink:
That does sound like a bad bug :!: |

Kinda sounds like a scam to get out of 32-bit CPUs. To bad that the date isn't closer, since 64-bit now is out.

Hopefully technology change before 2038.
Still we are flying on average 30 years old airplains. Just to recomple application programs is not always possible - source code went to trash bins and developers gone fishing or do some gardering. 2^31+1 in fact in kernels, not like in Y2K applications and these kernels in many situations are embedded. Somebody will have some fun around 18 January 2038, especially because most of the teens nowdays have no idea even how electricity works. |

Thats your company, but there is no video game for the pc yet that supports 64-bit, I think, also barly any 64-bit video encoders.

But... Linux already runs in 64-bit mode on AMD64 (Opteron, Athlon64) processors (and soon FreeBSD and NetBSD will, too). So people running Linux on an AMD64 just have to recompile mencoder and instantly get a 64-bit video encoder (it might not take full advantage of the larger data path, but should still be faster than a 32-bit-compiled version). |
NetBSD was the world's first OS to run on a 64 bit platform. The Alpha.
http://www.netbsd.org/Ports/alpha/ Linux came way later. FreeBSD also runs on Alpha and is currently being tested on IA-64 and AMD64. -kwag |
Don't forget about the UltraSparcII... we had a whole lab of 300MHz Ultra 5 workstations put in in 1999 and they blew away all the other systems at the school (except possibly the 450MHz P3s from IBM, which were mainly used to play Quake 3 :-) )
But AMD64 and PowerPC G5 processors are the first 64-bit systems readily available and cheap enough for home users... Alpha systems were cool, though (still would be, but I think they stopped production on them). I remember reading about them in high school and thinking "1GHz processors! I'll never have one that fast!" :mrgreen: They're still the best for numeric computations (although the Itanium processors are supposed to be as good or better, I haven't had the chance to use one though)... |
Yeah, the UltraSparcII and the Alphas are really cheap now at E-Bay :)
I bought a couple of "Multias" a couple of years ago, and I installed NetBSD on them. They were SLOWWWW and hot :lol: But the worked fine as a small ftp and web server. NetBSD should run really great on the Sparcs. I've been told that NetBSD on Sparc runs circles around Linux (on the same machine) :cool: As a matter of fact, NetBSD and FreeBSD (not Linux!) are being used here: http://ctd.lerc.nasa.gov/5610/tcpextensions.html extensively :!: -kwag |

KA9Q, yeah, reminds me of my early days when I got my Extra Class Amateur license, and I did a lot of experimenting via HF bands with his program. I also used Mike Pechura's (WA8BXN) MSYS program, which was my first FTP experience via amateur radio, at 300 baud :D Fun days :cool: 73's DE KP4QG ;) -kwag |
