Zope subscription activity
by Ken Manheimer 03 Sep '99

03 Sep '99

Here's a bit of incidental info about zope.org mailing list subscription that may (or may not) be interesting to some of us. I've been collating it weekly, using a python script i made to go through the mailman subscribers log. I suspect the charts are structured a bit unconventionally - it may take a bit of effort to understand what they're saying. The instructions are below - i'll just note a few key concepts: - Each entry (line for a week) indicates the change in subscription activity for that week. - The stuff in the '+' side indicates the *net* gain in subscriptions - those above the number that are cancelled out by unsubscriptions. (Instead there's a '-' side in those rare cases where unsubscriptions outnumber subscriptions.) - The stuff in the '.' side (either plus or minus) indicate balancing pairs of subscriptions and unsubscriptions - which rob recognized as being the "churn". - When necessary, the charts are normalized (to fit in the alloted space), in which case each tick represents more than a single subscription action. - The totals may not jibe with the actual subscribership of the represented lists because some of the lists predate the mailman subscribers log file (from which the stats are derived). I may someday spend a bit more time to log these things somewhere on the web site, for visits by anyone with interest (as they might web log displayers). Not immediately though - not high enough priority. (Pardon me if the chart formats are obscure - they're really tailored to my particular purposes, and may not be obvious in general...) (And pardon my mania for character graphics - i confess i really enjoy seeing what can be done within such wooly constraints...) -----.----- *>=====[_]L) (<= i dunno know who made it) -'-`- Ken Manheimer klm(a)digicool.com -=- -=- -=- These charts convey the flux in subscriptions of the following mailing lists: <All> zope zope-announce zope-dev zdp zope-packagers zope-checkins digicool-cvs How to read the charts: Each chart covers the weeks from the start of the mailman subscribers log to the current date. (Each week sample begins on sunday, so the first and last week samples may cover less than 7 days.) The curves themselves depict two things for each week: - The net gain or loss in subscriptions for the week, and - The "churn" in subscriptions, ie the number of new subscriptions that are cancelled by resignations All stats are indicated with character ticks around a centerline normalized for each graph: - Net gains are indicated by '+' sequences to the right of the centerline, - net losses by '-' characters to the left, and - churn by '.' sequences, on the opposite side from the week's net coup. The numeric magnitude of the respective gain/loss/churn is indicated by numbers at the extreme positions of the sequences. Since the sequences are normalized to fit in the width of a page, some of the ticks constitute more than a single subscription (gain/loss) or subscription pair (churn) - that factor is indicated with a note at the top of such graphs. It's important to note that the figures for the net changes are just the net - for a week with a net gain, the total number of subscriptions would equal the net plus the churn, while the number of unsubscriptions would be the same as that of the churn. Weekly, AGGREGATED subscription activity Total of 1918 subs, 721 unsubs, from 1999/01/24 to 1999/08/29 '+' = net gain - prevailing subscriptions, '-' = net loss - prevailing unsubscriptions, '.' = churn - mutually cancelling sub & unsub pairs. ** Each tick represents ~ 2.8 items ** Aug 29, 1999... 52................+++++++++++++43 Aug 22, 1999... 34..........++++++++++++++++++++64 Aug 15, 1999... 36..........++++++++++++++++++++++++++++84 Aug 8, 1999... 24......+++++++++++++++++++++++++++++++92 Aug 1, 1999... 52................+++++++++++++++++++++++++75 Jul 25, 1999... 28.......++++++++++++++++++++++++++79 Jul 18, 1999... 37...........+++++++++++++++++++++++++++83 Jul 11, 1999... 28.......+++++++++++++40 Jul 4, 1999... 36..........+++++20 Jun 27, 1999... 36..........++++15 Jun 20, 1999... 19....+++++++++31 Jun 13, 1999... 23......+++++++++++++44 Jun 6, 1999... 15...+++++++++++++44 May 30, 1999... 14..+++++++++++++40 May 23, 1999... 12..++++++++++++++47 May 16, 1999... 9..++++++++++++++45 May 9, 1999... 18....+++++++25 May 2, 1999... 21.....++++++22 Apr 25, 1999... 18....+++14 Apr 18, 1999... 10.++++++++28 Apr 11, 1999... 11.+++++20 Apr 4, 1999... 18....++12 Mar 28, 1999... 29........+4 Mar 21, 1999... 24......+5 Mar 14, 1999... 24......++++17 Mar 7, 1999... 16...+++++++++++++++++++58 Feb 28, 1999... 31........+++++++++++++42 Feb 21, 1999... 9..++++++++28 Feb 14, 1999... 14..++++++20 Feb 7, 1999... 6.+++++++++31 Jan 31, 1999... 14..++++15 Jan 24, 1999... 3.+10 ============================================================================= Weekly, zope subscription activity Total of 1156 subs, 495 unsubs, from 1999/01/24 to 1999/08/29 '+' = net gain - prevailing subscriptions, '-' = net loss - prevailing unsubscriptions, '.' = churn - mutually cancelling sub & unsub pairs. ** Each tick represents ~ 1.5 items ** Aug 29, 1999... 32..................+++++++++17 Aug 22, 1999... 23.............++++++++++++++++++31 Aug 15, 1999... 25..............+++++++++++++++++++32 Aug 8, 1999... 15.......++++++++++++++++++++++37 Aug 1, 1999... 34....................+++++++++++++++++++++35 Jul 25, 1999... 23.............+++++++++++++24 Jul 18, 1999... 27...............+++++++++++19 Jul 11, 1999... 23.............++++++++++19 Jul 4, 1999... 25..............++++++12 Jun 27, 1999... 21...........+++++++13 Jun 20, 1999... 16........++++++++15 Jun 13, 1999... 16........+++++++++++++++++29 Jun 6, 1999... 13......+++++++++++++++++29 May 30, 1999... 9....++++++++++++++++27 May 23, 1999... 6..++++++++++++++++++30 May 16, 1999... 5..+++++++++++++++++++33 May 9, 1999... 15.......+++++++++17 May 2, 1999... 14.......+++++++14 Apr 25, 1999... 9....+++++10 Apr 18, 1999... 8....+++++++++17 Apr 11, 1999... 6..+++++++++16 Apr 4, 1999... 10....+++++11 Mar 28, 1999... 15.......+++6 Mar 21, 1999... 14.......+3 Mar 14, 1999... 15.......+++++11 Mar 7, 1999... 11.....++++++++++++++++++31 Feb 28, 1999... 19..........++++++++++++21 Feb 21, 1999... 9....+++++++++++++++++28 Feb 14, 1999... 14.......+++++++++++20 Feb 7, 1999... 6..+++++++++++++++++++31 Jan 31, 1999... 14.......+++++++15 Jan 24, 1999... 3.+++++8 ============================================================================= Weekly, zope-announce subscription activity Total of 245 subs, 13 unsubs, from 1999/01/24 to 1999/08/29 '+' = net gain - prevailing subscriptions, '-' = net loss - prevailing unsubscriptions, '.' = churn - mutually cancelling sub & unsub pairs. ** Each tick represents ~ 1.3 items ** Aug 29, 1999... 6...+++++++++++++++22 Aug 22, 1999... 3.++++++++++++++22 Aug 15, 1999... 2.+++++++++++++++++25 Aug 8, 1999... .+++++++++++++++++++++31 Aug 1, 1999... 1.+++++++++++++++++++++++++35 Jul 25, 1999... 1.+++++++++++++++++++++++++36 Jul 18, 1999... .+++++++++++++++++++++++++++++++++++++++++++60 Jul 11, 1999... .+1 Jul 4, 1999... .+ Jun 27, 1999... .+ Jun 20, 1999... .+ Jun 13, 1999... .+ Jun 6, 1999... .+ May 30, 1999... .+ May 23, 1999... .+ May 16, 1999... .+ May 9, 1999... .+ May 2, 1999... .+ Apr 25, 1999... .+ Apr 18, 1999... .+ Apr 11, 1999... .+ Apr 4, 1999... .+ Mar 28, 1999... .+ Mar 21, 1999... .+ Mar 14, 1999... .+ Mar 7, 1999... .+ Feb 28, 1999... .+ Feb 21, 1999... .+ Feb 14, 1999... .+ Feb 7, 1999... .+ Jan 31, 1999... .+ Jan 24, 1999... .+ ============================================================================= Weekly, zope-dev subscription activity Total of 282 subs, 180 unsubs, from 1999/01/24 to 1999/08/29 '+' = net gain - prevailing subscriptions, '-' = net loss - prevailing unsubscriptions, '.' = churn - mutually cancelling sub & unsub pairs.

Fiends of ZOPE, I see that ZOPE 2.0 is released. Can I use the current Database Adapters with Zope 2.0. I am especially interested in MYSQL and POSTREGESS. Currently I am running 1.10.3 with Python 1.5.1 and RedHat 6.0. Thanks in advance for any info.

What is a ZClass and how do I create one? I can't find any documentation on it, and it's not in the drop-down thing. Am I just missing some gold mine of documentation or is there really none on some of these things? While I'm at it, I did see the ZCatalog thing in the drop-down add box, but have no idea exactly what it does or how to use it.

I am trying to do this:  (substitute any other date thing for DayOfWeek) When I leave off fmt, the date is displayed, but it is ugly and with an unnecessary timezone, so I want to display it as I wish. when, BTW, comes from a gadfly database.

Or, a >quick summary to put on a main page that would display only the title >and use the URL as a link. With Zope2, this is pretty easy, actually. You can make an Event ZClass that has the properties you wish. You can then put these Events in a Folder somewhere (let's say it's /events). In /events, you can make an index_html DTML Method that looks something like this: <dtml-var standard_html_header> <dtml-in "objectValues('Event')"> <a href="<dtml-var id>"><dtml-var title></a> </dtml-in> </dtml-var standard_html_footer> This will list the titles of all of the Event objects as links to the object themselves. If you give the object an index_html method, then you can provide more detail about the event when someone clicks on the link. That method (which would be part of the ZClass) could be something like: <dtml-var standard_html_header> <table> <tr> <td>Time:</td><td><dtml-var eventtime></td> </tr> <tr> <td>Place:</td><td><dtml-var place></td> </tr> <dtml-var standard_html_footer> >I thought about putting a bunch of separate documents in a folder, but >-- I can't access that from its siblings. Ie, if I have a folder >named ACLUG/Events, I can't access it from ACLUG/Info (apparently?). >Also, I'd have to know all the names. And, that still doesn't let me >write some quick script to go through there and pick out only upcoming >events or some such thing. Is a Gadfly thing useful here? I couldn't >find a reference on that either (just a brief tutorial). You're probably thinking of acquisition when you say that you "can't access that from its siblings". Acquisition gives you automatic access to objects higher up in the hierarchy. However, you can still get to other objects by doing things like this: (some method in /Info) <dtml-with "PARENTS[1]"> <dtml-with Events> ...work with the events... </dtml-with> </dtml-with> Plus, ZCatalog gives you a way to access all sorts of objects from anywhere in the site in just about any way you want to.

How do the rewrite rules impact accessing things like /manage?

So any object (or at least documents and methods) can act as a variable? Neat! Question: How does <!--#var quicklinks> (as is found in the documentation) differ from <dtml-var quicklinks>? When should each be used? While discussing variables, how does typing in Zope work? I know that properties have types. What I want to do is read in a date from a user with an input form and then compare that to, for instance, a date in a Gadfly database -- or even just an arbitrary date. How can I tell Zope (or Gadfly) that it's dealing with a date? I didn't seem to find any casting operators around anywhere. > If you do really want it in Zope, you could use XML-RPC or ZClient to update > things via cron. Where can I find documentation on these?
