If I can, Using the type=! Or, everything except selector, can I exclude multiple entities? My code is /execute @e[type=lightning_bolt] summon lightning_bolt. I also want to exclude the player.
I've asked this question towards a developer for Minecraft and I thought I'd ask here too since they might not see the question.  How do I select all but two types of entities in Minecraft?  For example, something like: /say @e[type=![Player,Item],r=50] (to clarify I also tried type=Item,Player, type=Item,type=Player etc)  Should select any entity that does not match players or items, so things like Creepers, Ghasts, XPOrbs, PrimedTNT and so on within a radius of 50 blocks and print them to the chat.  Instead it ignores one of the flags, and works with the other instead.

I have never posted a link to this subdirectory anywhere, yet searching Google reveals that Google has found these pages on my site and indexed them.  Further, I updated the site with a robots.txt file that WMT reports as being read, and testing the blocked pages using the WMT test tool indicates that the pages will not be indexed. Apparently this does not remove the pages from existing results, though I submitted a request to do so.  How did Google find these pages to begin with? Is it because I used a common subdirectory name and Google guesses at common subdirectories? What is the difference between new/delete and malloc/free? Compute the integral $\int_{A} x^m y^n z^p (1-x-y-z)^q dx dy dz$ Correct way to use include and includeonly when writing a large document like a thesis Let $A$ and $B$ be two real $n\times n$ matrices such that $AB-BA=A$ Prove that $A$ is not invertible and that $A$ is nilpotent.  My attempt is the following. It holds that $AB=(B+I)A$ If $A$ were invertible, $B=A^{-1}(B+I)A$. Taking trace on both sides yields $tr(B)=tr(B)+n$, hence $n=0$, which is a contradiction. I can't prove that $A$ is nilpotent though. integral of $\int_{0}^{1}\frac{\ln(x^{2}+1)}{x+1}dx$ using contour integration? I have an interest in contour integration. I am not that good at it, but I enjoy learning what I can about it.  Here is a version of a rational log integral rarely encountered.  $\displaystyle \int_{0}^{1}\frac{\ln(x^{2}+1)}{x+1}dx=\frac{3}{4}\ln^{2}(2)-\frac{{\pi}^{2}}{48}$  I can do this using real methods (via double integral and substitution). I can post my workings if anyone would be interested.  My question is, can this be evaluated using contour integration due to the limits being $[0,1]$ instead of $[0,\infty)$?.  Contours may not be the most efficient way to go about it, but what is the course of action when the limits are 0 to 1 instead of 0 to infinity?. Check for column name in a SqlDataReader object Photoshop To CSS: How do you translate Fill to CSS I have a content box in photoshop with the background color #bc0018 with a 65% opacity and 50% fill.  I am able to translate the backgroundcolor and opacity part to this, but without the 50% fill the backgroundcolor looks different.  .content-box {     background-color: rgba(188, 0, 24, 0.65); }   Any suggestions on also getting the proper "fill" in CSS?  EDIT  I did just divide the opacity by half and it appears to achieve the same effect as a 50% fill. Still, I would love to hear how other people do this? I definitely don't want to create an image just for this.  .content-box {     background-color: rgba(188, 0, 24, 0.325); }   Thanks! How to send form input values and invoke a method in JSF bean How to get this only in small letters (lowercase)? I used the following code to give out the category name (without link) in a single post.  How would it be possible for the category name that is given out to only appears in small letters ?  I just think this has to be made with substring, but I dont get it :) Could somebody please help me :)  &lt;?php foreach((get_the_category()) as $category) { echo $category-&gt;cat_name . ' '; } ?&gt; count vs length vs size in a collection From using a number of programming languages and libraries I have noticed various terms used for the total number of elements in a collection.  The most common seem to be length, count, and size.  eg.  array.length vector.size() collection.count   Is there any preferred term to be used? Does it depend on what type of collection it is? ie. mutable/immutable  Is there a preference for it being a property instead of a method? How to programmatically close a JFrame My parents are Indian Citizens. They hold a valid B2 Tourist Visa to USA. I'm planning to book a flight with Hyderabad (India) - Abu Dhabi (UAE) - Dublin (Ireland) - USA. The leg from Hyderabad to Dublin is operated by Etihad and I know there is no problem hopping at Abu Dhabi. The leg from Dublin to US is operated by Aer Lingus. I called Aer Lingus customer care agent told me a transit visa is required to land in Dublin. She did not care to ask for the citizenship of traveller or about the USA visa. I went through Irish immigration website - (), India is not in list of countries that require transit visa. I'm now confused. Can some one confirm if they traveled with the same itinerary recently  Update: I called Aer Lingus again. Another agent told as long as I don't exit the airport, a transit visa is not required. I think these people don't really understand trouble we go through when boarding is denied. I put this question because I read a person was denied boarding earlier - . His case mentions about denied because of different day. But I see his transit time is 12 hours only. Messed up Blender models when exporting to Unity3D I have modeled a simple pocket watch in Blender. Every time I import it into Unity3D, regardless of whether I export it from Blender as an FBX or 3ds file, it always comes out missing faces! Why is this happening? I have never had problems importing models into Unity3D like this before.  Blender Screenshot    Unity Screenshots     It seems to me that different faces appear when I rotate it differently. How can I prevent this? Thanks! How to run an encrypted virtual machine? How does ServerName and ServerAlias work? It's the following part of a virtual host config that I need further clarification on:  &lt;VirtualHost *:80&gt;   # Admin email, Server Name (domain name), and any aliases   ServerAdmin example@example.com   ServerName  141.29.495.999   ServerAlias example.com ...   This is and example config, similar to what I currently have (I don't have a domain name at the moment).  &lt;VirtualHost *:80&gt; - Allow the following settings for all HTTP requests made on port 80 to IPs that this server can be contacted on. For instance, if the server could be accessed on more than one IP, you could restrict this directive to just one instead of both.  ServerName - If the host part of the HTTP request matches this name, then allow the request. Normally this would be a domain name that maps to an IP, but in this case the HTTP request host must match this IP.  ServerAlias - Alternate names accepted by the server.  The confusing part for me is, in the above scenario, if I set ServerAlias mytestname.com and then made an HTTP request to mytestname.com, there would have to be a DNS record pointing to the server's IP for this to work? In which case, is ServerAlias just basically EXTRA ServerName entries?  Say I had a DNS entry such that foobar.com = 141.29.495.999 but then I had ServerName = 141.29.495.999 and ServerAlias was empty, would that mean that although foobar.com gets resolved to the right IP, because there is no reference to accept foobar.com in ServerName or ServerAlias?  Or something. Man I'm confused. Time Complexity of $T(n)=T(n-2)+\frac{1}{\log(n)}$ Currently, if you access a deleted question you will get a short message informing you that the question has been deleted. However, if you click on a direct link to a deleted answer or comment (which you can get via notifications), nothing is displayed.  This is naturally quite confusing as you will get the message about a new answer or comment via notifications, click on the link and simply see nothing.  Therefore, I propose to display some sort of message to the user, informing her/him that the answer or question has been deleted. Note that this is different from always showing a deleted answer/comment, as I specifically request it in case you access the specific URL.  One example for a comment would be:   One example for a deleted answer is:   This question is related to ,  but requests a feature to circumvent the problem altogether.
