Updating the SubscriberKey on the All Subscriber table through the API I'm trying to update an existing Subscriber in the All Subscriber Table through the API; i've set up the AppId in the App Center and have connected and created Subscribers, but i'm still having issues updating.  What call do I need to be making to do this? These are the ones i've been trying. Seeking options for Spatial ETL (Extract, Transform, Load)? I am interested in the pros and cons of various spatial ETL (extract, transform, load) tools.  If you have used the items listed here (or add your own), I seek your opinions and experiences.  In particular I would like to see usability comparisons of:    (proprietary)  (proprietary, subset of FME features)  (open source)  (open source)  (I don't know that it is truly ETL, but more of a file translation toolset) Any additional lot listed   There is no need to give a review of ALL software mentioned.  If you are experienced with even one then that will be very beneficial in making a decision about which direction to go.  Example: I am looking to create a schema conversion function that will allow me to select the input layer, create a translation, and output to a new, pre-defined schema.  Optimally, after creating the translation script, I would like to have an interactive form where I can "map" fields in my input layer to the output layer (ie- The output layer will have a field called "Address", what is it called in the input layer?)  Some were mentioned in the Q&amp;A at   And here are a couple of related articles that I found. If $f,g:X \to Y$ are continuous and $Y$ is $T_2$, then $\{x \in X\,|\,f(x)=g(x)\}$ is closed I'd like to know if the following proof is valid.  The only thing I'm not sure about (though I can't see why it's invalid if it is) is if we can always use the Hausdorfness of $Y$ to separate an open set from $f(C)=g(C)$.  "Let $X$ be a space, $Y$ a $T_2$-space, and $f,g:X \to Y$ continuous functions.  Prove that $C:=\{x \in \,|\,f(x)=g(x)\}$ is a closed subset of $X$."  Let $x \in X$ be such that $f(x) \ne g(x)$.  Since $Y$ is $T_2$, there are open sets $U_\alpha \ni f(x)$ and $V_\alpha \ni g(x)$ such that $U_\alpha \cap O_\alpha=V_\alpha \cap O_\alpha=\varnothing$ for all $\alpha \in A$ where $A$ is the set indexing the points of $f(C)=g(C)$, and $O_\alpha$ is an open set containing $x_\alpha \in f(C)=g(C)$.  Let $U:=\displaystyle\bigcap_{\alpha \in A} U_\alpha$ and $V:=\displaystyle\bigcap_{\alpha \in A} V_\alpha$.  Then $U \cap f(C)=V \cap f(C)=\varnothing$.  Therefore, since $f,g$ are continuous, $f^{-1}(U)$ and $g^{-1}(V)$ are open sets in $X$ disjoint from $C$.  Since $X\setminus A$ is the union of such open sets, it is open itself and therefore $C$ is closed.  Thanks. Short story about astronauts landing on a planet of shapeshifters I'm trying to find an English-language short story I read in a collection about five to ten years ago (I don't have any idea of the original publication date).    Here's everything I remember:   The story is about human astronauts landing on an alien's planet, from the alien's point of view. Every organism on the alien planet is part of a single hive mind, and they can telepathically infect the humans (the aliens view this as beneficial, as any mind separated from the hive must be suffering), but choose not to once they realize that there's an entire planet of humans out there. The narrator alien is an organism that was designed by the hive to mimic a non-essential component on the spacecraft, so it can stow away when the humans return to Earth. The narrator alien is preparing to infect all of Earth as soon as the shuttle's door opens, but the component it replaced was the wire that opens the door, so it is fried instantly by the current.   Despite knowing all these elements of the story, I haven't had luck Googling it, because so many of these elements are very common sci-fi themes on their own, and I don't remember any unique names/terms.  I don't remember if I read this in a Sci-fi anthology book, or in a magazine (like 'Asimov').  Thanks in advance if anyone can help me track this one down, it's been bugging me for a long while. Does a spellcaster know when concentration ends? Does a spellcaster know when concentration ends on one of their spells?  For example, when a wizard casts invisibility, that target is invisible until they attack or after one hour. So if the character attacks and the spell ends is the wizard aware that their spell that they are concentrating on ended earlier than expected? Who should I be damage buffing as Mercy Ever since mods gained the ability to undelete comments, deleting them has become easier as the confirmation dialog was removed.  However, this is not the case in the mod queue &mdash; I still get a confirmation dialog for each comment I want to delete in the queue under a custom-flagged post (single-comment flags can be deleted just fine). And since this is the place from where I delete comments the most, it can be annoying.  In addition, the "purge comments" button, when invoked from the queue, refreshes it, so I have to scroll back down, remember which post I just purged, and mark the flag as helpful. Usually not a big issue but if there are multiple "obsolete comments" flags, then it can get confusing.  Could the workflow for comment thread moderation from within the queue be improved? Ideally, make comment deletion work like everywhere else on the site, and make the purge button AJAX-based like the comment deletes. How to twist radial vector to make spirals? Automatically resize uploaded images Possible Duplicate:             Could large images of more then 640 pixels wide automatically be resized to reduce loading time and band width use? Not that I have a prehistoric internet connection here, but sometimes pages seem to need unnecessary time to load fully.  I just resized the image  from 179 kb down to 32 kb using a 15% compression rate. I think that is already worth it, although there have been much bigger downsizes in the past.  This feature then propably should/could be combined with , and uploading an image then would result in the following post addition:  [![enter image description here][2]][1]  [1]: http://i.stack.imgur.com/ZSBxw.gif "View &lt;image title&gt; full sized" [2]: http://i.stack.imgur.com/VXmBA.jpg "&lt;Image title&gt;"   Update:  I now understand from  that images áre resized already, but that post authors have to do some changes themselves.
