Peripherals/Devices

Hi, I'm getting set to create categories for PDP-10 and PDP-11 peripherals/devices (I've been doing a lot of organization on the CPU/system/etc end of things, and have that in pretty good shape now). Which word would be better to use, if you have an opinion - 'peripherals' or 'devices'? We current do already have a Category:Peripherals, so maybe go with that? Jnc (talk) 16:05, 19 February 2018 (CET)

I tend to go with 'peripherals' in this case. Larsbrinkhoff (talk)

OK; I'll get started on that. And also, I think we should have a category for all DEC stuff - just plain 'DEC', or 'Digital Equipment Corporation'?

DEC is consistent with the other labels. Larsbrinkhoff (talk)
I'll have to ponder the DEC category name. It feels a bit 'thin', just plain 'DEC'. I don't mind the acronym 'DEC' as part of the name of sub-categories (it prevents them getting ridiculously long); but for the main category, it feels too informal. Jnc (talk) 20:28, 19 February 2018 (CET)

Other cats

BTW, I added some thoughts about cats to Help:Introduction to Categories#Current organization - does that seem like a good system? Jnc (talk) 19:44, 19 February 2018 (CET)

There's one problem with the taxonomy. Not all PDP-10 (or 11 or 8) operating systems are DEC operating system. At least not in the sense "operating systems made by DEC". Larsbrinkhoff (talk)
I'm happy to subdivide it (them, actually) into two other categories; any snappy ideas for the name(s)? I suppose we could have 'DEC Operating Systems' and 'Non-DEC Operating Systems'; each of which is further divided into, e.g., 'DEC PDP-11 Operating Systems' and 'Non-DEC PDP-11 Operating Systems'. Jnc (talk) 20:28, 19 February 2018 (CET)
That'll potentially be a lot of category pages to create! Can't a page be in both the DEC Operating Systems category, and the PDP-10 Operating Systems category? Larsbrinkhoff (talk)
Sorry, I'm not sure I'm seeing your concept; a concrete example would help. What pages (and sub-categories) would go in 'DEC Operating Systems' category, and what in the 'PDP-10 Operating Systems'? ITS would clearly be in the latter, but would it be in any others? What super-category would the 'PDP-10 Operating Systems' category be in? Jnc (talk)
TOPS-10 would be in both 'DEC OSes' and 'PDP-10 OSes'. OS/8 would be in both 'DEC OSes' and 'PDP-8 OSes'. ITS would be in just 'PDP-10 OSes'. Unix V7 would be in just 'PDP-11 OSes'. 'DEC OSes', 'PDP-8 OSes', 'PDP-10 OSes', and 'PDP-11 OSes' would all be in 'Operating Systems'.
This way, there would be N+M categories (for N manufacturers and M architectures), rather than NxM. Larsbrinkhoff (talk)
Ah, got it.
The only potential downside to that approach is that there's no easy way to find non-DEC OS's, other than going through all the per-machine OS categories - for which having a 'OS's for DEC machines' super-cat would be mildly helpful, as opposed to just putting them in 'OS's'.
Ah, how about a single 'non-DEC OS's for DEC machines' category? (Although it would need a snappier name than that - can't come up with one quickly.) So TOPS-10 would be in 'DEC OS's' and 'PDP-10 OS's', Unix V6 would be in 'non-DEC OS's' and 'PDP-11 OS's', etc.
That's only one more category, and it would help find the non-DEC OS's easily; and no PDP OS article would have more than two category tags. (I'm going to put off for now the issue of OS's like MUMPS, which started out as a private venture, and which eventully wound up as a DEC product! :-)
BTW, actually my orginal proposal was not N*M; it was Sum(2*Mi), instead of Sum(Mi), where Mi is the number of architecture for manufacturer i, out of N. But still, you're right, it would have been a lot! Twice as many as the other way... Jnc (talk) 15:04, 20 February 2018 (CET)
Now that I see the 'Non-DEC Operating Systems' Category, it does look quite strange.. on the surface of it it would cover everything that's not DEC or for DEC, i.e. most operating systems (and then a visitor would wonder why it's named that way, too.) But then it's definitely for DEC, just not made by DEC. It gets a bit confusing. Tor (talk) 09:20, 23 February 2018 (CET)
I agree, actually! Despite thinking about it for several days, I just couldn't come up with a short, snappy name that, on its face, described what the category was about! 'Non-DEC Operating Systems for DEC Machines' is a bit ponderous! If anyone can come up with a better one, I'd be happy to change it (which is why I put off going around tagging articles). I asked Lars if he had a suggestion...
In the interim, that's why I put the description in the Help: page (and the cat header), to warn people it's not what the name, strictly-speaking, implies. Jnc (talk) 14:06, 23 February 2018 (CET)
So Lars mentioned 'external', and synonyms for it... independent, outside, foreign, non-proprietary.
Of these, 'Independent DEC OSs' wouldn't be too bad - I'd be OK with switching to that. 'External DEC OSs' initially sounds like it might be the best, but it could be misunderstood as still being a product of DEC, for use outside the company (and the same applies to the others, too).
Although it still doesn't describe exactly what the category is, 'Independent' does 'on its face' clearly indicate there's something unusual (i.e. it doesn't clearly give a wrong impression), and gives a strong hint of what it really is.
The problem is that the shortest facially accurate description (i.e. without any external amplification) is 'non-DEC OSs for DEC machines', which is long and clunky. Anything shorter is going to have some lack of clarity. E.g. 'Independent DEC OSs' - what exactly is that - if you don't already know?
Anyway, whatever solution we come up with for DEC, we can use for any companies that need it - e.g. 'Independent IBM OSs'. Jnc (talk) 15:00, 23 February 2018 (CET)
And.... crickets. Oh, well! Jnc (talk) 13:57, 27 February 2018 (CET)
No use overthinking this. Full steam ahead! Larsbrinkhoff (talk)
OK. Hey, I'm from MIT - according to some people, over-thinking things is what we do! :-) Jnc (talk) 21:17, 1 March 2018 (CET)

Terminal categories

So I recently split up Category:Terminals into Category:Printing Terminals and Category:Video Terminals. There's also a Category:DEC Terminals. So, currently all the DEC terminals (VT52, etc) are tagged with two categories: 'DEC Terminals' and 'Printing/Video Terminals'. Is this the way people want to go, or should we create 'Printing' and 'Video' sub-categories of 'DEC Terminals'? Jnc (talk) 03:55, 8 June 2018 (CEST)

Unix OS cat?

I've noticed that there are a lot of systems in the top-level category Category: Operating Systems; the majority are Unix derivations of some type or other. I propose to move them all to a new 'Unix clones' category, so only truly one-off systems like CTSS, etc are in the top-level cat. Additional query: what should the cat be called - 'Unix-based Operating Systems', or what? Jnc (talk) 18:00, 10 June 2018 (CEST)

Sounds ok to me. Would that be a sub-category in Operating Systems then, easily found at the top of the page? As for the name - I think 'Unix-based Operating Systems' is fine. Tor (talk) 15:28, 17 June 2018 (CEST)
oK, good, I'll make it happen. Yes, it will be a sub-cat of Category: Operating Systems. I think I'll use Category: Unix-based OS's, though, to keep it from being too clunky. Jnc (talk) 17:55, 17 June 2018 (CEST)
Ah, in retrospect I should have used the full 'Unix-based Operating Systems'; now most of the sub-cats in Category: Operating Systems use the full 'Operating Systems' in the name, so the Unix ones are now somewhat 'odd cats out'! Sigh! Jnc (talk) 02:26, 18 June 2018 (CEST)

Another idea: I currently have two cats (the first below, plus 'everything else'),but maybe we should have three categories:

  • Unix versions done by Bell/ATT
  • Unix versions which are external descendants (Ultrix, Sun, etc)
  • Unix 'clones' (Linux, Coherent, etc)

Comments? (And names, if the idea is desirable)? I wonder into which do the later BSD's fit - IIRC, they eventually got rid of all the Bell code? Jnc (talk) 17:13, 18 June 2018 (CEST)

Category work

After I created a new article on an obscure video terminal board, it was pointed out to me that since no other article linked to it, Web indexers wouldn't find it. I realized that if every article is in a category which is included in some way in one of the main categories, which are linked to on the Main Page, that would do it. So I'm going to try and improve categories and cat tags, make sure all articles have the desired tags, etc. Jnc (talk) 00:40, 11 June 2018 (CEST)

Background category?

In line with the concept that all articles should be in a category, to make sure Web indexers can find them, I started to think about articles on background/fundamental topics (e.g. virtual memory). They don't really fit into any existing top-level category. At first I thought about creating a new top-level category for them, but I realized I don't need to, at least to make sure there are no 'orphan' articles; in general, those pages were all created in response to red links in existing articles (which do all tend to be in categories), so if those are all in categories, Web indexers will be able to find the background articles too. Still, so people think it would be useful to have a catgory for them? If so, what shoud it be called? Jnc (talk) 00:49, 11 June 2018 (CEST)

I don't think trying to fit everything into a category is necessary when it doesn't particularly improve anything. Tor (talk)
