Does an Artificer (Artillerists) Eldritch Cannon provoke opportunity attacks?
Can you make an opportunity attack against a moving object?
My Panda USB wi-fi adapter works just fine on 16.10, but when I try to connect to my wi-fi router in 17.04, GNOME network manager reports "Connection failed." I did some tinkering, and noticed that my MAC address for my wifi adapter, according to GNOME, is DIFFERENT every time I make it forget my wifi settings and try to reconnect. Any leads on a possible fix or work-around?   I'm running Ubuntu GNOME 17.04, kernel 4.10.0-19-generic, GNOME 3.24.0. Make back/forward work on paginated lists I often hear people saying that "I am" is the shortest sentence in the English language.  I know that there are also discussions about sentences using the imperative mood such as "Go." that would be shorter, but my question is this:  Why would we (the people saying "I am" is a full sentence) not accept "I'm" as a complete sentence?  Is there some unwritten rule about contractions that says "I'm" wouldn't be correct? Drawing Day and Night on a Google Map I'm looking to plot day/night on a Google map, for an arbitrary point in time. I'm familiar with generating map tiles; I'm just looking for an algorithm to tell me whether a particular point on the globe is currently in daylight or darkness, or to otherwise plot the curve of the day/night interface onto the map.  I've done some searching, but it's possible I don't even know enough about the problem domain here to know what terms to search for!  Any ideas? Doesn't have to be perfect -- basically, I'm comparing Flickr geolocation data of sunrise and sunset photos (and their "date taken" timestamps) with reality, and this is to help me visualise it. Do I keep my Windows installation if I install Ubuntu with Wubi, the Windows installer? Copy files excluding x,y,z causing error in shell script shortcut key to detach a tab in firefox (move tab to new window) In FF, I can move a tab to a new window by either dragging the tab out of the browser, or right clicking the "move to New window" option from the context menu. is there a shortcut key to move the current tab to a new window without dragging or using the context menu, or a way to set one up?  Often, I like to look at 2 tabs side by side, so I drag one out, then hit WINDOWS KEY+→ to put the detached tab on the right, then ALT+TAB to tab back to the main window, then WINDOWS KEY+← to put the main window on the left. It would be great if I could do the whole process on the keyboard.  I checked  documentation and did not find any shortcut key for detaching a tab: Eclipse returns error message "Java was started but returned exit code = 1" Free ornaments font I'm looking for a free ornaments font. I know about  and pifont. Where can I find more glyphs? prevent php classes from being extends Partial Sums of Geometric Series This may be a simple question, but I was slightly confused.  I was looking at the second line $S_n(x)=1-x^{n+1}/(1-x)$.  I was confused how they derived this.  I know the infinite sum of a geometric series is $1/(1-x)$.  I just can't figure out how the partial sums, $S_n(x)$, have $1-x^{n+1}$ on the numerator.  How was this derived?  Thank you.     Example 5.20.   The geometric series   $$     \sum_{n=0}^\infty x^n   = 1 + x + x^2 + x^3 + \dotsb $$   has partial sums   $$     S_n(x)   = \sum_{k=0}^n x^k   = \frac{1 - x^{n+1}}{1 - x} \cdotp $$   Thus, $S_n(x) \to 1/(1-x)$ as $n \to \infty$ if $|x| &lt; 1$ and diverges if $|x| \geq 1$, meaning that   $$     \sum_{n=0}^\infty x^n   = \frac{1}{1-x}   \qquad   \text{pointwise on $(-1,1)$}. $$   (Original image .) Can I get UAC prompt for user from batch file? Can I get UAC prompt for user from batch file?  For example I need put some keys to registry under CurrentControlSet from batch file by     reg import path\to\my.reg   PS. runas is not a solution as my customers uses different Windows localisation and I can not guess which name used for Administrator account (this can be Администратор)...

Nothing shows up in the terminal when I type my password When I'm about to install a program in the terminal it wants the password:  [sudo] password for xxx:   But when I start to type my password nothing happens. What should I do? How can I use an array modifier to create individually manipulatable objects? I often use an array modifier (or two) to quickly create a grid of identical or symmetric objects, which can be really useful when modeling all sorts of man-made objects. Once I've made the grid, though, is there any way for me to make it so that each of the objects are individually manipulatable?  Simply applying the modifier does not seem to be the full answer, since it still only allows me to select the grid-of-objects as a whole in object mode. Is there any way to separate them so I work with them each individually? Problem Currently, I am playing on a server where hoppers transport items at the rate of 64 items a second, and this has proved very difficult to build a sorter for. I'm not at all proficient in Redstone building but have tried building basic sorters and ones that I have found on YouTube and I haven't gotten anything to work. Solution Hopefully one of you is really good at Redstone and can help me design a sorter that can work under these conditions. (I need the sorter that can sort items while I AFK kill witches with a looting 47 sword P.S. most of the problem is with the sorter itself because no items will stay in the sorter hopper (bc the whole stack goes into the chest so the hopper doesn't have anything to go off of to sort) so any solution to that would be helpful as well. Need help finding a good book on Riemann Geometry Output of Logistic Regression Prediction I am trying to install Packet Tracer 7.3 (latest version) on Ubuntu 20.04 but do not succeed to so so because of two dependencies which are not installable ("libdouble-conversion1" and "qt-at-spi").  However I successfully installed the previous version (7.2.2) which was available in an Ubuntu installer format (.run file) but I nothing happens when I run it from my gnome desktop.  I am quite a newbie in Linux so I appologies if answers are obvious...  Thanks in advance ;-)  Denis
