I was already intrigued by the structure of the Feferman-Levy model, and was wondering what sort of sets hide there. This made me things worse, it is a paper I will have to read eventually. Arnold Miller is a good writer too, he writes with humor hidden between the words.
cool. I wrote a little script to show the down votes you cast. I was worried because it misses deleted contributions, but since you can't "un vote" them, it seems fine.
at least until the zombie (post) apocalypse
fwiw: 50% of my downvotes are on deleted contributions, so i've got 2 permanent downvotes on my record
my profile reports 4 downvotes, but my reputation reports 2, and I vaguely remember 2 answers getting deleted after my vicious downvoting and namecalling
If they're downvotes on answers that are now deleted, I presume the rep drop was undone when the answers were deleted. Maybe check math.stackexchange.com/reputation and compare with your displayed rep?
my rep is about 95 higher on the site versus on the rep calculator. i've already lost about 300 to rep recalc though, so i'm waiting for my 10k + 95 to recalc
(oh and my script just runs through the reputation page, that's where it gets the downvoted answers)
@JackSchmidt I'd take the opportunity to recalc before hitting 10k+95, to lose and regain the privileges, or to see whether or not the privileges are given by the /reputation page. It's an interesting question.
i think it doesn't add too much to our cost, but it could be our weird accounting (we mostly only pay the human labor; electricity is on separate budgets, and I think the acrylic is cheap)
@tb Oh, because I am willing to risk bringing down SE just to see if we can fit 24 people in a chatroom? For possibility, I wasn't really thinking about the crash, more about the availability of 24 people wanting to be in the chatroom at the same time.
@robjohn: Looking at the page source, it seems as if there is an upper bound and then a link saying "more" is presented so that you can expand the box: last two entries of the source for the box are: <li id="present-user-25053" class="present-user user-container user-25053" style="opacity: 0.15; visibility: visible; width: 32px;"> <!-- some further stuff> <li class="more" style="display: none;" title="show -24 more"></li>
@yayu: This may be true. But do you think such safety helmets are actually effective? Anyone only slightly familiar with how students function will know that after their graduation/PhD. people will have forgotten 100% of such mandatory material.
So I wonder who thinks that it is worth the effort inflicting such things on unwilling students.
@t.b true. Though I think these courses are intended to get marketable terms into a student's CV. So if someone chooses to apply to a bank etc, they can show that they have had such and such course. Ofcourse, having gained a degree in math they would be expected to get quickly familiar with such subjects if their employment required it.
It is a bit unfair to make these courses mandatory though, and I agree.
It's about a fairly complex issue from Mahjong but I tried to make it simpler:
Given is a number Q as well as b black and w white tiles. Repeatedly draw a tile. If it is white, toss it away and draw again until the first black tile is drawn. The result is Q plus the number of whites drawn (i.e. minimum Q+0 and maximum Q+w). What is the average result?
(Unfortunately, I need to step out for quite a while; just type out the rest of what you have and I'll get back to you later unless somebody does it for me in the interim.)
