md, Here's where I saw the reference to Fortran V wrt Voyager's CSS... https://www.allaboutcircuits.com/news/voyager-mission-anniversary-computers… From http://www.quadibloc.com/comp/fort04.htm.... IBM never defined a language called FORTRAN V, or provided a compiler for it, but some of its competitors used the term for their extended versions of FORTRAN. Univac and Data General are two companies that sold compilers for a language which they called FORTRAN V. In general, FORTRAN V compilers included the CHARACTER data type as a standard feature of the language, and they added the ENCODE and DECODE statements as well. These statements allowed a character variable to be used instead of an input-output device as the source for a formatted read, or the target of a formatted write, and they looked like this: CHARACTER*80 BUFFER ... ENCODE(80,11,BUFFER),X,Y,Z ... DECODE(80,10,BUFFER),P,Q,R ... STOP 10 FORMAT (3F12.5) 11 FORMAT (3F12.5) END Mike On Thu, Apr 21, 2022 at 6:20 PM Jon "maddog" Hall <jon.maddog.hall(a)gmail.com> wrote: > I had not heard of Fortran 5 (or Fortran V) and a half-hearted search of > the Internet did not find anything. > > Do you have any pointers to it? > > Thanks, > > md > > On Thu, Apr 21, 2022, 18:09 Mike Peckar <mpeckar(a)gmail.com> wrote: > >> According to the Guiness Book of World records, The computer system that >> has been in continual operation for the longest period is the Computer >> Command System (CCS) onboard NASA's *Voyager 2* spacecraft.

Re: Uptime!

by Dan Davis

A branch for my company has one remaining Solaris box that keeps up a service or two with a ridiculous uptime and they recently built a new facility. In a meeting we were discussing the move plan for their entire IT kit and they asked me about the feasibility of moving the Solaris box across town on an UPS so they wouldn't have to shut it down. I kindly asked them to reconsider because while they might keep power applied for the whole ride it'd be unlikely that the disks would survive the trip.

Re: Uptime!

According to the Guiness Book of World records, The computer system that has been in continual operation for the longest period is the Computer Command System (CCS) onboard NASA's *Voyager 2* spacecraft. This system has been in continuous operation since the spacecraft's launch on 20 August 1977. Voyager 1's CCS uptime trails it by a couple of weeks and both are still going. Each Voyager has two CCSs, two Flight Data System (FDS) computers and two Attitude and Articulation Control System (AACS) computers, but the FDS & AACS do not operate continuously. The CCS's have two 18-bit word, interrupt type processors with 4096 words each of non-volatile plated wire memory amounting to 69.63 kilobytes. They execute about 81,000 instructions per second and transmit data back to Earth at 160 bits per second. They were originally programmed in Fortran 5.

Re: Uptime!

by Jon "maddog" Hall

Mike, Believe it or not, both VMS and Digital Unix systems were the same way. They would go months and years without rebooting. The US Navy had two hospital ships, the "Mercy" and the "Hope". One stationed on the East Coast and one in San Diego. The one on the East Coast used WNT for the servers and the one in San Diego used GNU/Linux. The ship using WNT had to have twice as many servers as the one in San Diego because the Navy rules said that a WNT server HAD to be rebooted every 30 days, whereas there was no such requirement for GNU/Linux. Since a Naval deployment could last longer than 30 days, and since they needed the server services to be up constantly that whole time, they needed twice as many WNT servers. md On Thu, Apr 21, 2022 at 8:58 AM Mike Peckar via WLUG <wlug(a)lists.wlug.org> wrote: > Fun Story, Maddog.

Thankfully, fewer reboots and maximized uptime will become a feature in most distro/OSs. *RHEL has kpatch* https://www.redhat.com/en/blog/overcoming-vulnerabilities-live-kernel-patch… *Ubuntu has Live kernel patching and the new needrestart package* https://ubuntu.com/blog/an-overview-of-live-kernel-patching https://ubuntu.com/blog/ubuntu-server-21-10 *Windows 2022 (😂😁😂)* https://techcommunity.microsoft.com/t5/windows-server-essentials-and/window… Hopefully the future will have fewer reboots since the pace of vulnerabilities doesn't seem to be slowing down at all. I, for one, am very happy to see the technology maturing to match reality. 😁 Enjoy the weekend!

Re: Uptime!

This machine was a "ghost ship." It's use had long come and gone and people had moved their stuff off onto new machines. It was running 32bit RHEL 5.5 no patches, no nothing. It was a security risk at this point. To Mike's point, unless there's good change control, you run the danger of having a machine that's not ever going to reboot sensibly. A couple years ago I stumbled upon a linux box that was running an ancient version of mysql.. the database was up, but it was running out of a directory like /u01/mysql/bin The disk /u01 was LONG gone.. but the database continued to run.. it's data was being written off on to a different disk and things worked.. but it was clear that machine would never had rebooted.

Additionally if you never reboot, how do you know the machine WILL reboot? How do you know what the system will do after a power failure, etc? Fate will intervene at some point and force you to reboot whether you want to or not, so you should be prepared with the knowledge of how the system will respond to that.
