How feasible would it be to run a Bukkit/Spigot/whatever server and sync it with a PocketMine server?  Ideally, players would be able to interact (see and chat) with each other even if they're on different servers, and the world map would sync as well, so structures and terrain would be the same and update when changes are made.  I know this would require custom plugins.  Assume the servers are either on the same machine or the machines have a high-speed connection to each other. I want to know if there are any technical issues with doing this type of setup.  The only big problem I can think of is differences in available items, but that can be worked around by only allowing items/blocks present in both versions of the game.
My kids are playing Minecraft on 2 PCs, creative mode.  They are connected by the way of one of them starts a single player game on the other one than joins that game over the LAN.  Can I, using Minecraft PE on my iPad, join their game as well?
Uncheck checkboxes by changing particular checkbox state I have custom fields in contacts form named checkbox1__c, checkbox11__c, checkbox12__c, checkbox13__c.  When I check checkbox1__c then I want checkbox11__c,  checkbox12__c,  checkbox13__c to be unchecked.  When I unchecked checkbox1__c then I want checkbox11__c, checkbox12__c, checkbox13__c to be checked.  Is there any way to do this by using validation-rules? If not no way to this by validation-rules, then what is the best way to do this? Do people sometimes get blocked by a webservice for things someone else has done with their dynamic IP-Address It is common practice for operators of web services (e.g. web sites) to block IP addresses when there was malicious traffic originating from that address.  It is also common practice that internet users don't have a static IP address but get one assigned by their ISP via DHCP.  Now I would expect that it sometimes happens that a specific IP address gets banned from a service and later that address gets assigned to another user, leaving the new user (temporarily) banned from the service for no apparent reason. However, I never had this problem or heard of someone having that problem.  Does this sometimes happen? If not, what prevents this from happening? Properly discontinuous action: equivalent definitions Let us define a properly discontinuous action of a group $G$ on a topological space $X$ as an action such that every $x \in X$ has a neighborhood $U$ such that $gU \cap U \neq \emptyset$ implies $g = e$. I would like to prove that this property is equivalent to, having given $G$ the discrete topology and in the $X$ locally compact Hausdorff case, the map $G \times X \rightarrow X \times X$ given by $(g, x) \mapsto (x, gx)$ being proper (i.e. closed and preimage of compact sets is compact) plus the action being free.  I have managed to prove one direction, that is, if the action is proper and free with $G$ having the discrete topology then it is properly discontinuous. I'm having trouble though with the other direction. Here is an attempt: let's denote by $\rho : G \times X \rightarrow X \times X$ the map $\rho(g, x) = (x, gx)$. Suppose $K \subset X \times X$ is compact. We wish to show $\rho^{-1}(K)$ is compact. Let $(g_i, x_i)$ be a net in $\rho^{-1}(K)$. Then $\rho(g_i, x_i) = (x_i, g_i x_i)$ admits a convergent subnet, so passing to it we may assume $x_i \rightarrow x$ and $g_i x_i \rightarrow y$. Essentially we must now find a way to prove $g_i$ converges, but I can't seem to do this. Any hints? Can't install/uninstall packages in Debian I'm trying to install/uninstall packages in Debian but getting errors.    I can't remove or add any package, always getting the error.

Mark Zuckerberg decided that people are allowed to open groups under the following restrictions:      1) No two different groups can exactly the same participants.      2) The number of users in each group is even.      3) Every two group has an odd number of common users.      Denote by $m$ the maximal number of groups that can be formed in facebook under the restrictions mentioned above. Prove $m \leq n$.   I tried solving this by defined a matrix, multiplying it by its transpose and using some rank considerations I thought I could derive the bound, but I didn't succeed. Could you please give me a hint?  The question had anther subsection : prove that in the case that $n$ is even than we have stron inequality Overflow to left instead of right I have a div with overflow:hidden, inside which I show a phone number as the user types it. The text inside the div is aligned to right and incoming characters are added to right as the text grows to left.  But once the text is big enough not to fit in the div, last characters of the number is automatically cropped and the user cannot see the new characters she types.  What I want to do is crop the left characters, like the div is showing the rightmost of its content and overflowing to the left side. How can I create this effect? Package in Java Can I use film that's 20+ years old? In an  about The Force Awakens, the author suggests that:      Rey is Luke’s daughter.   I’ve missed any indicators of any such relationship while watching the movie.       For instance, I took neither Luke’s lightsaber calling out to Rey, nor her hug of consolation with General Organa as such. Is there any evidence that Luke is Rey’s father?    Is it known who Rey’s parents are? No more updates for Google Chrome 32-bit I am using Google Chrome 48.0 32-bit.

Help me find the name of a space TV show from the early '90s I don't recall much about the show, and I think I only ever saw one episode, and my Google Fu is not up to snuff today.  The episode, most likely the pilot, came out around the same time as Babylon 5 and then just disappeared.  From what I remember the show was about the (small) crew of a ship. The cockpit of the ship was a upright bed-like contraption, and the cast were investigating a ship that had a radiation leak or something adrift in space.  There was a cast member who could shape-shift, similar to Odo from Deep Space 9, and another member was a barbaric warrior.  There was some sort of mystic stuff, but I may be confusing that with Babylon 5.  Overall the show was very similar, in my memory, to Deep Space 9 and Babylon 5 so I may be confusing things, but I do remember how I saw the similarities in the show to those shows and knew it wasn't the same show.  Any help? What is included in Wolfram Extras? Does the sequence $$\displaystyle \frac{n}{\sum\limits_{k=1}^{n}\Big(\frac{k}{k+1}\Big)^k}$$   converge?   Attempt. Since $\Big(\frac{k}{k+1}\Big)^k \rightarrow 1/e\neq 0$ and the terms are positive, the series $\sum\limits_{k=1}^{\infty}\Big(\frac{k}{k+1}\Big)^k$ diverges to $+\infty$. I find hard to determine if $n$ or the sum goes faster to $+\infty.$   Thanks in advance. Yesterday I had 3,606 reputation but today I have 3,592.  My profile shows that I lost 6 reputation when a user was removed, but that would put me on 3,600 - 8 reputation has magically disappeared.  Adding up all of my reputation does work out at 3,591 (I'm assuming by default new users have 1 rep, so that would make sense).  Somewhere a reputation change since yesterday isn't being displayed. I don't know what this would be for, but -8 would lead me to believe that someone removed their up-vote on an answer I'd posted which already had a down-vote (could it be from that deleted user?).  I don't know if this is a bug or if there is simply a delay between reputation updating, but I figured it was worth reporting.    Sadly I cannot prove that I had 3,606 reputation yesterday. Tool for cleaning LaTeX code Is there something like indent for LaTeX? I have a collaborator that is using Scientific Workplace and the code it produces is totally messed up; I know I shouldn't expect miracles, but any machine support would be useful.  EDIT: This question is quite undefined without my comment to KeithB's answer; the idea is to save VC-friendly one sentence/one paragraph per text file line structure which SWT "fixes" by wrapping everything into fixed column width format. Wouldn't the thermodynamic cost of creating alternate universes make the Many Worlds interpretation implausible? Is the 'Tough' feat's additional health still added when Wild Shaped/Shapeshifted? Following on from this question:   It seems all feats carry over to your new form if your new form is capable of using them (so Mounted Combatant and Inspiring leader would usually be ruled as unusable in most circumstances). But what about Tough?     Your hit point maximum increases by an amount equal to twice your   level when you gain this feat. Whenever you gain a level thereafter,   your hit point maximum increases by an additional 2 hit points.   Would this increase your maximum HP by the same amount when in the form of a rat, or brown bear? Java - How to reduce the size of third-party jars to reduce the size of your application
