@StefanKottwitz In that case, why not say goodbye? Though granted, people don't always do it, even if nothing bad has happened. Maybe they think they will come back.
E.g. Daniel Burrows stopped working on Aptitude in 2011. And is apparently alive and well - was just looking at his Google+ page (no idea why anyone uses that). But he didn't post an formal signoff, nothing. Just stopped working on it.
@JosephWright i think the new Aptitude maintainers were trying to get in touch with him, but he didn't reply. Maybe they should have tried Google+. I've looked for Debian activity from him after 2011 and there doesn't seem to be any.
Presumably some of you here are familiar with apt.
@PauloCereda nah can't do one of those (mancunian accents were not that common in the University, although I may possibly sometimes have frequented the local pubs...)
@FaheemMitha yes was a Joke really, It's north of where I grew up
@AlanMunn -- another distinction between "pie" and "tart" is the shape of the crust. a tart usually has a vertical edge (as in the picture of the linked lemon tart), while a pie typically has a sloped edge, with the top of the pie wider than the bottom. and there are some "uncovered" pies that i would never consider to be tarts (and would find very peculiar if covered): pumpkin or squash, banana cream, and the kind of cream pie that is used to throw in someone's face.
"boston cream pie" is something else again; it's really a cake, the wikipedia description is pretty good.
@egreg -- i think it might just actually be possible a day later. my mother had memories (and pictures) of a snowstorm in baltimore on april 19, which was her birthday, and, coincidentally that year, palm sunday. so easter would have been april 26. (but april 25 is pretty close to "latest".)
@FaheemMitha -- if you're a publisher, and have to exhume old papers to publish an author's "collected works", altering existing documents is a very bad thing!
@JosephWright -- kindly remember that tex was created largely because of math, so for math publishers (still just a small audience, on the outer edges of "penalty copy") this is a big deal.
@barbarabeeton If the full moon happens on 20 March and the next is a long moon, the next full moon is 29 days later, that is, 18 April. If 18 April happens to be a Sunday, Easter is on 25 April. It's not possible it falls later. Conversely, if the full moon is on 21 March and it's on a Saturday, Easter is on 22 March.
@egreg -- i don't disbelieve you. i just know that the occasion i mentioned was backed up by a newspaper that my mother had saved. someday when i have lots of free time, i'll undertake to find the article in the newspaper's morgue.
@egreg -- another question on the timing of easter: what accounts for the difference in when easter is celebrated according to the eastern and western rites? it sometimes happens that they do not coincide. (this means that we get to enjoy the special treats from both traditions, and don't have to choose.)
@hillbilly There are certain cases where it will be removed. If the other person is currently the only one in the conversation or it's their answer, then they will always be notified.
In those cases, it's removed because it's just extra textual noise :)
@barbarabeeton The Orthodox Churches still use the Julian Calendar, so 21 March is 13 days later than ours. The rule for determining Easter is the same, but with this delay.
@egreg however, we don't fix ourselves on 21 March, but on the equinox moment. Once it happened that the equinox was only minutes from a new moon, which meant that the IAU had to decide/clarify
@SeanAllred Yes, of course. But they refused the calendar reform, so they didn't cut the 10 days and the 3 non leap secular years in between, which means their church calendar is out of phase by 13 days. So they have Christmas on (our) 7 January, but, as far as Church is concerned, it's 25 December.
@egreg I'm sure that the time of the national holidays in European states is the one given by the relative position of the equinox, the full moon (sorry, not new moon of course) and the Sunday midnight, as determined by IAU.
@egreg not true. Equinox is the moment when the center of the sun crosses the astronomical equator and is independent of the location. So is the full moon moment of course.
@SeanAllred The difference just depends on the different calendars used. Since the Nicaea Council decided that the date to consider is 21 March (possibly at Jerusalem, but I'm not sure) and not the astronomical start of Spring, confusion ensues.
@egreg I have a hard time (ha!) keeping straight the differences in time zones – I don't need to add calendars to the mix :) I can trust everybody knows when they celebrate holidays and go 'woo!' when needed :)
To me, getting the exact date right is paying attention to the wrong sorts of things :)
@FaheemMitha -- to ensure reproducibility, the ams stores within the document the version of latex and of every package used, so that a document can be recompiled even years later with no changes except for page numbers and perhaps application of errata. the goal is exact correspondence of line and page breaks, and those can easily vary with just the use of a different version of a single package.
even reprints are re-texed, and copy-checked for breaks; any difference would require a new proofreading, which is not cost effective!
@egreg they were, to some extent. So were old Jews for determining whether a new month has started. They counted 28 days, then they waited for the raising new moon. If they didn't see the small crescent, they announced a 29-day month and the new month started one day later.
@egreg -- i don't know what happens in other parts of the world, but in this country, i'm pretty sure the first day of spring is celebrated on the actual vernal equinox (although i'm not sure according to what time zone). so it's not always march 21.
@FaheemMitha -- yes, a polilcy decision that breaks should be the same. this is a policy of long standing, and it became much more important now that there is "dual publication", on-line and on paper. as i've said before, math has a long shelf life, and it's not unusual to have citations to documents even a century or more old.
@PauloCereda -- those must be odd ducks!
@egreg -- yes, which is why one has to check the calendar every year.
@yo' In summary, it's all conventional. ;-) With more precise astronomical data than were available before year 1000, it could be possible to have a more accurate determination according to the rule, but since the rule is already a convention, why bother?
@yo' The calendar reform was made just in order to avoid that Easter could fall too late in Spring, for instance because agriculture work was based on Easter. For the Eastern churches, Easter can fall as late as May 8 (May 9 after 2099).
@yo' Not really. There are other factors involved. For instance, the Paschal moon this year was yesterday (April 4), which should have made Easter the same for Eastern and Western churches, but the “official” full moon, with the calendar used by the Orthodox is later. ;-)
@yo' The Orthodox don't use astronomy at all: they use a fixed calendar, independent of astronomical data. And they don't bother if their full moon is not really full.
@JosephWright I think it's not bad this way, at least here, because we've got no other public holidays in March and April, but we've got 2 Holidays on May (other than Pentecost, which is not a Holiday here).
@JosephWright -- oh, i wish! in the u.s., there is a "presidents' day" holiday in february, which the ams doesn't observe. next before that is "martin luther king day", on a monday in mid-january, and after that, it's a drought until "memorial day", the monday nearest to may 31. these are federal holidays; different localities and school systems have their own schedules. (i keep suggesting april 1 for an ams "special", but nobody listens.)
@barbarabeeton Our big gap is August bank holiday (last Monday in August) to Christmas day (the latter isn't a bank holiday, it's a customary holiday, so we don't get one in lieu it if it's at the weekend)
@yo' Moreover, we don't have holidays around Whitsun, so it doesn't really matter. We used to have holiday for the Ascension (Thursday, 40 days after Easter) and Corpus Domini (second thursday after the Ascension). Now they're moved to the nearest Sunday. So the sixth Sunday of Easter time is Ascension and the Sunday after Trinity is Corpus Domini.
@JosephWright -- fall here is just dripping with holidays! "labor day" (first monday in september), in some places, "columbus day" (monday nearest october 13), "veterans day" (formerly armistice day, monday nearest november 11), "thanksgiving" (fourth thursday in movember, and at ams, the following friday), then christmas (december 25, if on a weekend, so be it).
in rhode island, "victory day" (end of wwii, truce with japan, monday closest to august 6); i expect that will vanish within the next few years, since ri is the only state to observe it.
@barbarabeeton Like I say, there was some talk of moving one (early May holiday), but that got stymied on the grounds late October/early November is not a good day to have off in England!
@barbarabeeton Like I said, we loose Christmas Day if it's on a weekend as it's not technically a bank holiday (it was a holiday before they were introduced)
@yo' When I was a boy, we had a wealth of school holidays. School started October 1, ending mid June. The holidays were 4.10*, 1.11, 2.11*, 4.11, 8.12, 22.12-6.1 (Christmas holidays), 11.2*, 19.3, Easter holidays from Maundy Thursday to Easter Monday, 25.4, 1.5, Ascension, Corpus Domini, 2.6. Not all were work holidays (marked *), but for them you had to add 1.1, 6.1, Easter Monday, 29.6 and 15.8. Good days!
@egreg the children have a handful of extra holidays: 8-9 weeks in summer, 2 days in autumn, 1-2 weeks for December, 1 day in January, 1 week in February-March, 2 days for Easter.
@JosephWright Later it was decided to cut on holidays. ;-) So now we have 1.1, 6.1, Easter Monday, 25.4*, 1.5*, 2.6*, 15.8, 1.11, 8.12, 25.12, 26.12. The three marked * are civil holidays.
@JosephWright Yes, I can't exclude it was holiday in some Italian State before 1861; it probably wasn't in Piedmont, so when Italy was unified, it was dropped anyway, because laws of Piedmont were extended to the whole new State. But the matter has always been very variable during time.
@barbarabeeton Ah, you've solved my class of exceptions to the 'pies are uncovered' rule. Yes, that's exactly right. And in fact the sloping vs. vertical side part is really the main distinction with the added proviso that tarts are never covered, I think.
@AlanMunn -- happy to be of service. i did ignore the "half covered" instance where a pie has an openwork lattice on top. i certainly don't remember ever having seen a "regular" crust on a tart, although i believe i've seen decorative elements of crust, like leaves. but now that i think of it, "pop-tarts" are fully wrapped in crust. (if they weren't, they couldn't be put in a popup toaster. they seem to be a commercial adaptation of a "pasty", a pastry-wrapped, hand-holdable edible.)

@yo' I suspect that many, many duplicate closes are to questions asked or answered by the first closer. We have a good memory for that sort of thing, and they're really fast to search for. So yes. :)
@yo' Also, that was one of my 'for the good of the site' questions.
@PauloCereda @PauloCereda, we must be the only LaTeX users in Brazil (or perhaps the world) who watch Maronite masses -- but the last one I was really there. The only other crazy guy I know about who uses LaTeX is Gareth Hughes, check out his XeSyriac package: users.ox.ac.uk/~wolf2305/xesyriac.html and a monk (yes, a monk) who uses LaTeX to write Syriac.
@PauloCereda Nope, it's more than 100 km away from home. Anyway, I'd always thought they could do better than their transliteration of Syriac, which no one knows here by the way, but I haven't offered my services yet.
@egreg, @DavidCarlisle You'd like the latest one on c.t.t.: \if A\scantokens {A} Yes \else No \fi works but \if A\scantokens {Z} Yes \else No \fi fails [reason is obvious if you ask me :-)]
@PauloCereda Yes, that's him... Kinda weird, though, chatting 'bout this on tex.sx. Maybe that's because I followed your last serious interview here and couldn't find a brilliant question to ask you, besides raising the flag of TeX typography against ABNT. Perhaps one day we'll turn the tide and we'll be like in some country (Germany?) where you can style your theses and academic works however you feel like.
@Joseph :) I was about to send you an email later on today, but you were faster here in the chatroom! :) I'm recovering from dengue, it was a very complicated holy week for me. :) But I believe it's less painful than ABNT itself. :)
@PauloCereda Wow, go write your e-mail, I'll feel flattered. Yes, I was told that you can recover from dengue in a day or so; but ABNT is like malaria, once academically infected it will last till the end of your (academic) life -- unless you care, of course: then, there are some cures, TeX among them.

@egreg -- okay, i guess i have to recant. some web digging over dinner uncovered the fact that, in 1943, easter was indeed on april 25, and the weather for the previous weekend included 1.67in (about 4.25cm) of precipitation. so it probably started snowing on april 18 and continued into april 19. in any event, it seems there were more umbrellas than palms raised.

@DavidCarlisle Indeed: we've been speculating on how CERN manage the 'impact' stuff for funding (how your research applies to the world outside of academia)
@DavidCarlisle Some of the kit on our beam line is from CERN from many years ago (or at least it was: there was an upgrade last year here)
