I want to have an information button show up in chat so when you press it, it tells you information or teleports you somewhere. I heard it uses /trigger but I'm not sure how to use that. Does anyone know?
I want players to be able to click text to run an OP command even if that player is not an OP. For example something like:  Console: Do you want to enable Fly? [If you do, Please click here]  *Player1 clicks that text*  Console: /fly Player1   Is something like this possible?
Convert .bbl file to .bib file How can I convert a .bbl file to a .bib file. I  lost my .bib file but I still have my .bbl file. Now , I need to add more references to my .bbl file according to a specific format which I need to produce using Bibtex, so how can I convert my .bbl file to a .bib file so I can add the new references according to the format.  Thanks for any insight. Why would someone buy a way out-of-the-money call option that's expiring soon? I swing trade equity options every once in a while for fun. This morning I witnessed something I do not understand at all.  In the attached photo, why would someone purchase 6 contracts for .05 at $76.  I just can't wrap my head around this!    Scenario:   Underlying Asset: RY.TSX  Current Price: $71.70 Days to expiry: 4 Days     EDIT: It happened again the next day with 74, see new table with headers as per request:   My only reason for asking is because RY.TSX is the Royal Bank of Canada, this stock will not move multiple dollars in 3 days(expiry in this scenario).  Why buy 10 @ 74 for .04 each instead of just buying 10 @73 for .04 which would have gone through.  If you do the math(excluding commissions): .04 * 100(shares in a contract) * 10 contracts = $40 Stock moves to 74 and they are in the money lets say for .20 .20*100*10 = $200  I just don't see the reward as 99% of the time you will lose this wager, it is just not worth it even if it does happen once in a blue moon.  I can think of much better things to do with $40.  For the skeptics another screen shot to actually confirm this order: If $\tan(\frac{\pi}{4}+\frac{y}{2})=\tan^3(\frac{\pi}{4}+\frac{x}{2})$,then prove that $\sin y=\frac{\sin x(3+\sin^2 x)}{(1+3\sin^2 x)}$ If $\tan(\frac{\pi}{4}+\frac{y}{2})=\tan^3(\frac{\pi}{4}+\frac{x}{2})$,then prove that $\sin y=\frac{\sin x(3+\sin^2 x)}{(1+3\sin^2 x)}$    $\tan(\frac{\pi}{4}+\frac{y}{2})=\tan^3(\frac{\pi}{4}+\frac{x}{2})$ $\frac{1+\tan\frac{y}{2}}{1-\tan\frac{y}{2}}=(\frac{1+\tan\frac{x}{2}}{1-\tan\frac{x}{2}})^3$ Applying componendo and dividendo rule on both sides, $\tan\frac{y}{2}=\frac{\tan\frac{x}{2}(3+\tan^2\frac{x}{2})}{(1+3\tan^2\frac{x}{2})}$ I am stuck here. Gaming with Virtualbox, has it worked for you? Currently I am using Windows 8. I have a virtual box with Ubuntu set up for development. Aside from that I sometimes just want to relax and enjoy a game (Battlefield 3, Skyrim, Saints Row: The Third, etc) after hours of research and development.   I want to have my main machine with linux, and install windows on a virtual box.   What I want to know, from those who have tried or seen it:   How is the performance? I've never been clear on this but, even if I install the correct drivers on the windows box, will it matter? At least on this part, I'm just curious how it offload. Which drivers will matter the most.  Mouse and Keyboard integration, I'll be honest, sometimes the mouse integration in Virtual Box is a bit frustrating, mouse cursor disappears, etc.    I'm not sure if this is the right place to ask. I'm merely trying to come back to linux, yet I'm a PC gamer so I can't throw away Steam. I'm aware of the linux client, but most of those games won't work.   If there's a right place to ask this whether StackExchange sites or any other site let me know.   Cheers and I hope those in the same position find a middle ground. Java error: Implicit super constructor is undefined for default constructor If/When to move to secondary fermentation Digression from   What are the good rules of thumb for determining a. whether to use secondary fermentation at all and b. when to move from primary to secondary.  Preferably any rule of thumb should have both chemical and anecdotal rationale supporting it. Let $\mathscr{F}$ be a collection of connected subsets of a metric space $M$ such that $\bigcap\mathscr{F}\ne\emptyset$. Prove that $\bigcup\mathscr{F}$ is connected.   If $\bigcup\mathscr{F}$ is not connected, then it can be partitioned into two disjoint, non-empty subsets $A,B$. Let $x$ be a point in $\bigcap\mathscr{F}$. Then either $x\in A$ or $x\in B$. I don't know where to go from here. Active login not recognized on Super User I have a point layer in QGIS. Each point represents a tree and each tree has information about its height as an attribute. I would like to build a query/expression to select all those trees that have an other tree higher than 7 meters within their 20-meter-buffer (20 meter radius).  I managed to do this "manually" by creating a 20-meter-buffer around all trees higher than 7 meters (after the selection of the trees higher than 7 meters) and then selected the ones within the buffer but I was wondering if its possible with a query/expression.  (maybe with a bit more complex one)  Unfortunately I do not have PostGIS so this should be done with Select by expression or Query Builder if possible.  (It would be also helpful to know if it's simply impossible) Continuous bijection from $(0,1)$ to $[0,1]$ Does there exist a continuous bijection from $(0,1)$ to $[0,1]$? Of course the map should not be a proper map. returning a local variable from function in C Why $e^x$ is always greater than $x^e$? I find it very strange that $$ e^x \geq x^e \, \quad \forall x \in \mathbb{R}^+.$$   I have scratched my head for a long time, but could not find any logical reason. Can anybody explain what is the reason behind the above inequality? I know this is math community, but I'd appreciate a more intuitive explanation than a technical one. Deep confusion with conventions and signs in geometric optics This is an equation given in my book.     The question is why have they used a negative sign on the LHS?   Now, if you try to derive the mirror equation with simple geometry, you get  1/v +1/u =1/f . I got that equation without applying any signs there!  So what is the need to apply the signs ‘here'?   If i try to derive this equation ( the one in the photo ) i get the exact answer, but with the positive sign in the LHS. WHY we use the negative sign in the derivation, and then  again we use conventions while solving the questions? Significance of starting the Fibonacci sequence with 0, 1.... DISCLAIMER: I do not deal with in-depth mathematics on a daily basis as some of you may, so please pardon my ignorance or lack of coherence on this topic.  QUESTION: What is the significance of starting the Fibonacci sequence with $0,1$ ?  For instance, if I picked any two random integers, say 2 and 7, to start a sequence would I actually be creating some multiple or derivation of the Fibonacci sequence?  Is there a general mathematical explanation for the relationship between any sequence represented by $a[0] = x, a[1] = y, a[n] = a[n-1] + a[n-2]$ and the Fibonacci sequence?  Or, back to my example sequence, is there a general mathematical relationship between:  $2,7,9,16,25,41,66,107,173,280...$  and  $0,1,1,2,3,5,8,13,21,34...$  Perhaps the Golden Ratio explains it somehow?  Any help would be appreciated. Wrong posts number on Review section Lately it's happening to me this:  After completing one or more "First Posts" reviews, I go back to the Review Section main page:   And the post counter shows that there are still posts to review. I click the link to review them, but there is nothing.  Refreshing the page doesn't solve the issue: it shows the wrong number again.

I'm looking for a very simple way to add a watermark to my screen which should be shown whatever I'm doing, is it during a Zoom call, or is it when giving a presentation, or similar (I don't necessarily need it to show during fullscreen mode). The reason is that I want to record my screen using QuickTime Player, and the watermark should be on the video. I know that there are many post-production tools that offer adding watermarks, but I don't want to do any post-production, I want to have everything on screen while recording already. (I also know that there are screen recorders which offer placing a watermark to the end result. I'd rather also avoid using another screen recording software, but if I don't find any other way to do it, then I'm open to a simple, non-pricy alternative to QuickTime Player.) I've a Skype interview for PhD application (it will make me miss  today.) I've been asked, in advance, to prepare a short presentation and then there would be some discussion with the panel (I guess.) I expect that they will ask if I have some questions so, I'm wondering what are the best (type of) questions one might consider?
