Anyone want a UPS?

I can actually ping my UPS: > which is truly fun :) Yes, it is. Our "big" UPS (30kVA, 3-phase, for 30 minutes) has that via an external box, and our "little" UPSs have it built in (USHA cards). And I get to play^Wlook after them (well, it's a network device, right?) There's a standard MIB for UPSs with all sorts of useful things in it. Anyone who has a serial-only UPS should be able to rig something up with the NUT (Network UPS Tools) software: http://www.exploits.org/nut/ or by using something like a Sinetica NetCom box: http://www.sinetica.co.uk/ Every home should have one ;-) My main server at home is now on an APC UPS. It didn't used to be, because it had quite a long uptime when I got that particular UPS, and I didn't want to spoil that. I was waiting to see it roll past the magic 10000 hours (about 416 days; and no, it's not a PC) to switch it over -- and the day before that, we had a power cut :-( -- Pete Peter Turnbull Network Manager University of York

Can anyone point me to a description of the file format for a VMS backup file? I need to be able to read one on a unix (linux) system, but 'vmsbackup' doesn't recognize the contents of one of the vbn's and ends up core-dumping... (alternatively, is there a version of vmsbackup or something which can read full vms backups) Megan Gentry Former RT-11 Developer +--------------------------------+-------------------------------------+ | Megan Gentry, EMT/B, PP-ASEL | email: mbg at world.std.com | | | | | "this space | (s/ at /@/) | | unavoidably left blank" | URL: http://world.std.com/~mbg/ | | | "pdp-11 programmer - some assembler | | (DEC '77-'98) | required." - mbg KB1FCA | +--------------------------------+-------------------------------------+

Anyone want a UPS?

> Any reasonable UPS will be heavy, because big batteries are heavy :-) Yes. Although my machine room currently runs on two 2400VA boxes, (note: we use 220VAC here, not 110..), they will soon be replaced by two new systems that do 3000VA each, with a 500VAC feed. The fun part is, that they have modular run time by adding battery boxes ("stack em up!"), AND (what I just learned half an hour ago! %-] they have a provision for connecting an external generator. Which I have. :) (OKOK... legally I am not allowed to run that thing for extended periods of time, but I _do_ have permission to have it fired up for emergency purposes, soo... hey! ;-) I guess I'll spend the week between xmas and new year's rewiring, and doing power measurements on the circuits.... Oh- and the real fun thing is: both one of the current UPS'es, and the new ones, have ethernet SNMP monitoring..

Digital music (was: Interesting Tim O'Reilly article)

by Fred.van.Kempen＠microwalt.nl

Hi, Regarding the being able to work around expensive studios to produce music: yes. I know a (computer-audio-) guy who spent EUR 50K on a bunch of digital "studio" audio equipment (mixing, levellers, edit workbench, etc) and computers for work and storage (I did that part for them), and he then teamed up with an "analog" audio guy who set up the "analog" part of their setup (mikes, recording room, whatnot.) They now make a good living doing recordings and mastering sessions for artists in Holland and Belgium- both starting ones __and__ some known ones. They recently asked me to again help them with setting up a digital music distribution and delivery system, as their "customers" (artists) asked them to also act as their "record company" using New Media. When they have done the legal legwork, I'll be building an online record store for them, with an almost direct link to the studio. So... yes. It can be done, and it can work well. The traditional companies in that field are scared shitless, because THEY HAVE NO CLUE as to what's hitting them. Youth today _really_ doesn't care [anymore] about 101% [sic] pure audio quality, they are _fine_ with 192Kbps MP3/Pro files which then can then stuff onto a CD. I am, too, often. The proposed "album" price in the "shop" above was EUR 8 to EUR 10 (about same for US$), and their short investigation has shown that customers were OK with that, including the fact that they had to download the stuff. [Optionally, the "shop" will have a CD-R/DVD-R burning service, by the way, for, I believe, EUR 2.5 plus shipping] The latest rumor is, that a wellknown Dutch concert managing agency has contacted them whether or not they would be able and willing to handle _all_ their live recordings of gigs, including.. yes, the "shop". Traditionally, "live albums" are sucked dry by studios and recording companies- the artists get very little out of them. This "New Shop" (hey, that sounds familiar.. hmm...) doesn't have to, so artists AND fans benefit. Again, dunno where this is going, as it's not there yet. I am a consultant, so, advise on the technical issues. But, while busy doing that, I did notice that the "other" guys were scared shitless _all_ the time, and didn't know what to say _most_ of the time I was there... The same most probably goes for the video/movie industry... dunno about that world, but there, the "distribution channel" is even more powerful.... Cheers, Fred

The bitch is > heavy (over 100lbs). Any reasonable UPS will be heavy, because big batteries are heavy :-) Whether it's worth doing anything with it depends on whether you need a high-current or long-duration UPS. That one would allow you to boil the kettle for a cup of tea (or run the coffeemaker) during those power outages when there's nothing else you can do :-) It's not that hard to come by second-hand UPSs, the usual fault being that the batteries have gone bad (sulphated), and that's usually because people don't cycle them properly. There's some evidence to suggest that -- providing they've not gone too far -- high current high-frequency pulses can rejuvenate lead-acid batteries, and there are some circuits around designed to provide the remedy. I built one, and it seems to work, so long as the cells have *some* life left. Measure the voltage on each cell. If it's below 1V, or the cell looks at all swollen or distorted, it's past redemption. http://www.shaka.com/~kalepa/desulf.htm -- Pete Peter Turnbull Network Manager University of York

Vintage Intel Markings

Is there anything stamped on the bottom of the chip, a date code or ? I really don't know the variations but I would not be surprised to see a white and gold version in any of intel's early chips. I am no help there. Paxton Astoria, OR Who is digging out his microscope to look at his 1702s.

Which version of VMSbackup are you using to read the tape? I seem to have several.. V3.0, 3.1, 3.1.1, 4.1, 4.1.1 and 4.2 ... --f > -----Original Message----- > From: Megan [mailto:mbg@TheWorld.com] > Sent: Sunday, December 15, 2002 6:58 AM > To: cctech(a)classiccmp.org > Subject: Looking for pointers to specs... > > > > Can anyone point me to a description of the file format for a > VMS backup file?

OT: Re: Re: Interesting Tim O'Reilly article.

>What I'm referring to is the recording industry claiming their sales have >dropped. First of all, I want to see hard data to prove this. Second, I >want this dat to be from an independent auditor. Lastly, I want an >independent analyst to confirm whether this is because of rampant CD >copying on college campuses or if it is as a result of the economy. I can't link to the report, because I don't recall where I saw it (actually, I think I saw it in a local newspaper)... but there was one I read recently that did site hard numbers to show that sales of CDs from record stores have dropped over the last year (based on sales $$, they didn't quote counts, so it could be from lowered prices, but since I haven't noticed CD prices going lower, I doubt that). The numbers were of course given by the RIAA, with no source quoted (so the assumption is it is from their own internal book keeping). However, the article also nicely pointed out, that the figures the RIAA were quoting were specifically for sales from record stores (ie: Tower, Sam Goody, places like that). When asked about sales from ONLINE stores (like Amazon.com), the RIAA said they didn't have those figures available. Nor did they have available the sales from recording industry web sites that offer MP3 purchases or similar. Since they were claiming sales of CDs were down only something like 8 or 9 million... I think it is pretty darn reasonable to say that those missing dollars from store fronts could easily be accounted for from online sales (and far more $$ I am sure). This is the stuff you have to be VERY VERY careful to read between the lines when looking at anyone's "facts and figures". You can distort this kind of data into telling you anything you want it to say (I work in Market Research... we are experts at distorting reality with numbers!) -chris <http://www.mythtech.net>
