What is a primary decomposition of the ideal $I = \langle xy, x - yz \rangle$?

How to upload a file to a WCF Service? I've build a WCF Service to accept a file and write it to disk. The front-end consists of a page with SWFUpload which is handling the upload on the client side. Apparently, SWFUpload posts the data with a Content Type of: multipart/form-data.  I would think this ok but on the Service side I get an error. The error is "ProtocolException" expecting text/xml. I've tried different message encodings in the bindings but nothing seems to work.  How can I get this file uploaded using multipart/form-data? Any open subset of $\Bbb R$ is a countable union of disjoint open intervals Why do some Unicode text messages crash the iPhone OS? The description of the  says:     Your Intelligence score is 19 while you wear this headband. It has no   effect on you if your Intelligence is already 19 or higher.   The  spell description says that my Intelligence score becomes 1 on a failed save:     [...] On a failed save, the creature's Intelligence and Charisma   scores become 1. The creature can't cast spells, activate magic items,   understand language, or communicate in any intelligible way. [...]   If I am affected by Feeblemind and I am wearing the Headband of Intellect, would I have an Intelligence score of 19 or 1?   Also, what about the other effects like not being able to cast, activate magic items, understand languages or communicate in any way? Those seem Intelligence-related, but are mentioned additionally to the reduction.   If the Intelligence score becomes 19, are the other effects still active? Can I cast a spell while another spell or ability is resolving? My opponent has a  with scads of loyalty. I've got a  and a  on the battlefield.  He activates Sorin's "ultimate" ability, targeting Gideon.     -6: Destroy up to three target creatures and/or other planeswalkers.

Is there any way I can use the Spellbomb to prevent my opponent from stealing Gideon after he is sent to my graveyard? Sarrus Rule with LaTeX How can I solve the following sequence Let we have the following sequence  $$y_n= \frac{1}{\sqrt{n^2+1}}+\frac{1}{\sqrt{n^2+2}}+\cdots+\frac{1}{\  \sqrt{n^2+n}}$$ find the limit of the sequence $y_n$ decide whether it is increasing or decreasing How to Fix Broken Packages? How do I fix broken packages when it is not working? When I try to fix broken packages, it tells me to "fix broken packages." I've seen the  here before, as well as on many sites on the web.  I've also seen different info on what was covered.  I'm not a huge X-Men fan, but I do enjoy the characters and stories, so I know I'm probably missing out on a lot, and may have missed the obvious along the way because I didn't read a particular series or something like that.  I had a relative die from leukemia a few years ago and that reminded me of basic junior high science: that red and white blood cells are produced in the bone marrow and must be able to reach from the marrow into the blood vessels.  The leukemia my relative had was the kind where the "bad" cells would surround the marrow and prevent the new "good" blood cells from getting out to the rest of the body.  So just how much of Wolverine's skeleton is covered with Adamantium?  If it's the whole thing, there'd have to be openings for new red blood cells to get out if he is to remain alive.  I've never seen a reference to this issue, is it ever addressed?  That also raises another issue along the same line: Are hard to reach areas, such as ball and socket joints covered?  If not, then stress on other covered areas could be transferred to the weaker uncovered areas, which would lead to breakage there.  And if joints like that are covered, is there anything to say how it was done?  Are there openings or gaps in the Adamantium covering on his body?  Are there any references to any of these issues that deal with them? I am using natbib and agsm for harvard-style referencing. My related code is  \usepackage{natbib} \bibliographystyle{agsm}   Then I am using \citep{} for citations. My problem is that in text I am getting     (Author et al. 2012)   but and I want     (Author et al. 2012)   Does anyone know how to change this and get 'et al' in italics in the text?  I am using TexPad and BibDesk and I have not been able to find the .bst files in Terminal.  I know that it is often correct to have the 'et al.' unitalicised but my university regulations requires italics. Quick easy way to migrate SQLite3 to MySQL? Do the last digits of powers of a number $n$ follow the same cycle as the last digits of the number $n$'s last digit's powers? Should we sign-then-encrypt, or encrypt-then-sign? Frequently, we want to send messages that are (a) encrypted, so passive attackers can't discover the plaintext of the message, and (b) signed with a private-key digital signature, so active attackers can't make Alice think that a message came from Bob when it didn't. Is it better to (a) generate the digital signature from the (hashed) plaintext, and then encrypt a file containing both the plaintext message and the digital signature? Or is it better to (b) encrypt the message first, and then generate a digital signature from the (hashed) encrypted file? Or (c) combine encryption and public-key digital signatures in some other way? A closely related earlier question (  ) seems to focus on symmetric-key MAC authentication. As , Do the same issues with (symmetric-key) MAC-then-encrypt apply to (public-key) sign-then-encrypt? Under what conditions will healers switch targets? I've been using healers lately, which I haven't really utilized much before. I've noticed that they will sometimes switch targets, even when their original target still lives.   What conditions are needed for healers to switch targets? Can I draw something on my card and play tournaments with it? Just out of curiosity, what can I do to the card, so it's still legal to play it in official tournaments?   Can I draw something over ruling texts?  Can I draw something over artwork? Can I draw something over mana cost? Can I draw something over its name?   I'll be glad to see some official rulings about it. :) How do I identify which Linux distro is running?
