cctalk Digest, Vol 73, Issue 13

by athornton＠gmail.com

I agree that whether a student learns has much more to do with the student than what in particular they're studying. I quit my undergraduate physics degree when I had a moment of clarity that even if I managed to squeak through my Partial Differential Equations class with a C (I did) I'd still be on a trajectory where _solving PDEs was what I would be doing with my life_. My undergrad degree is in Ancient Mediterranean Civilizations. My MA is in History (but, hey, the History of Computing). I dropped out of the Ph.D. program I was in for a variety of reasons, to be honest crushing depression probably chief among them, but also because I was a fairly decent practitioner, and I had more fun playing with computers than I did writing stories about people who'd played with computers a couple generations before I had. It being the late 90s, my job prospects were decidedly better on the Not A Professional Historian side of the fence. That was 22-ish years ago. I'd been making beer money all through college and grad school with IT jobs, and I've stayed in IT-related fields ever since. Consulting, systems administration and engineering, these days software development-but-also-devops. My lack of appropriate degrees probably only didn't hurt because I started a not-unsuccessful consulting business with my mentor after I quit grad school, and by the time I was ready to move on from that, I had enough years of broadly varied experience under my belt that it didn't really matter. But that's tangential. The actual point was: the fuzzy stuff is only contemptible if you've got Physicists' Disease. History is hard, and it has a lot more in common with debugging that is obvious at first glance. In both cases you are presented with "Here's what happened," and it's your job to figure out "why?" In both cases, the ability to break the end-state down into a set of much smaller components which contribute to it is key--and although that ability probably _does_ have a lot to do with innate personality or preference, it's also very, very much a learned (and trained!) skill. The thing with debugging is that you usually are afforded the opportunity the repeat the experiment while changing parameters. With history, you're not so lucky, and thus you never _really_ know the root causes (you also usually don't know "what really happened", but by cross-referencing your sources you may be able to emerge with some sort of decent-consensus guess), but you can make more or less plausible and persuasive hypotheses about them. The idea that you are interrogating a recalcitrant witness is common to both history (and I would guess many of the humanities and social sciences) and creating and maintaining working software. I'll grant that it's _harder_ to surf blithely through an engineering degree than it is through a liberal arts degree, mostly because there are less-subjective metrics (particularly in lab courses) as to whether you actually learned something about what you're supposed to be doing. If I were being snarky, perish the thought, I'd say that the engineers who didn't really want to understand what they were doing were pre-meds. Nevertheless, a degree--and particularly an advanced one--is indeed much more about the discipline to put your head down and swallow what's put in front of you than about smarts. I was told a couple of decades ago I'd regret not having stuck it out for my Ph.D. I'm still waiting for that regret to kick in; in the meantime, many others have come and gone. Adam

FYI sunhelp.org down

by john＠ziaspace.com

> I posted to <rescue at sunhelp.org> and saw my message got stuck in the mail > queue. Upon a further inspection I saw that the domain has expired along > with `mrbill.net' where the nameservers used to reside and both have been > taken by someone else, taking the name service down for `sunhelp.org'. I > can still reach Bill Bradford's personal page when I connect to the server > by its IPv4 address at: <http://184.94.207.190/>. I noticed this, too. Since sunhelp.org uses mrbill.net DNS servers, and because the server at 184.94.207.190 is still up, we can still see the content if we make our own DNS, so I configured my server at 192.80.49.4 (athena.zia.io) to answer for mrbill.net, for sunhelp.org, for fiftieshouse.com, and for lispmachine.net, so if you want to see any of these, temporarily set your DNS server to 192.80.49.4. I did this in part to mirror sunhelp.org, but I suspect there are already mirrors out there. Sorry to hear about Bill :( John Klos

Searching for (DOS?) Backup Software

Hello, anyone heard of Genoa GenWare Backup Software and probably has a copy floating around?

Looking For Computer Automation LSI-3/05 Documentation

by tangentdelta＠protonmail.com

Hello. I have two card cages out of a pair of Linotron 202 phototypesetting machines, and have been hunting for documentation for the Naked Mini systems used in them for over a year now. The Computer Automation CPU boards in the systems have been a complete mystery to me until recently. To make a long story short, I happened to stumble across the patent for the machine (https://patents.google.com/patent/US4254468A/en), which has the same bus configuration as my card cages, and also provides some good evidence that "Naked Milli" 3/05 CPU boards were used. I've found documentation for the LSI 3/05's instruction set and an informative brochure, but nothing technical. Bitsavers has been a great help in my efforts to uncover more information about this processor, but there's still a lot of technical information that has eluded me (such as the autoload ROM, and how its data is arranged). The LSI-series computer handbook mentions a dedicated manual for the LSI 3/05, but I haven't found anything else about it online. If anyone has any information about the LSI 3/05, or where I might look for the manual, it'd be greatly appreciated. Thanks.

Maynard MaynStream

by van.snyder＠sbcglobal.net

I have a Maynard MaynStream tape backup unit from the 1980's. It uses audio-format cassettes with 1/4" tape, but it's a different tape composition, and the cassette has a notch in it to tell the device it's not just plain audio tape. The capacity was 80 MB per cassette. I also have four ISA controller cards, four cables, and several cassettes. We used it for backup with IBM PC/AT boxes many years ago. Does anybody want it? It seems a shame to throw it in the e-waste bin. Van Snyder van.snyder at sbcglobal.net

college study

by sales＠elecplus.com

My grandfather wrote a book, "This is the Way to Study" SQ3R was the system Study, Question, Read, Write, Review Look over the chapter, read the captions of the pics, look at the bold text then make notes of questions for things that pop up Then Read the chapter through Write down more questions read again to find your answers then do the problems at the end of the chapter look over everything again, and see if u understand it all have someone else quiz u, if needed then review it all, and u should have a good grasp on it My college friend says Wow, that is a LOT of work! Is there an expectation now that being educated is NOT a lot of work? -- Cindy Croxton Electronics Plus 1613 Water Street Kerrville, TX 78028 830-370-3239 direct
