So firstly, I used the buffer tool in Qgis3 to create (twenty) polygons with a certain width from (twenty) points. This lead to the situation below, where o1 and o2 are two original points and 1 and 2 are the resulting polygons. Now, I want points (like A in the picture below) from another point layer to have an attribute stating in which polygon they are. However, in overlapping situations I would like to see both polygon id's to be added, which does not happen when using the 'add polygon attribute to point' (which only adds one polygon id).     To resolve this, I need to have a different layer for each polygon, so I can use dummy variables. How do I create a different layer for each polygon? I have heard of the Split Polygon plug-in in Qgis2, but I am working in Qgis3. To clarify, I would like for both polygons to be kept intact, as I've seen others wanting the overlapping section belonging to only one of the polygons.
I am using QGIS and I created a vector grid on a crop field in order to cut it into plots. I want to save each grid cell into individual polygon shapefiles automatically.  Here is an example of a vector grid I would like to split into 117 shapefiles:    Eventually, I did it manually with the selection tool and "Save as" but it is really time-consuming when there are more than 100 plots to save.    Is there any way to do it faster and more automatically?  Each plot as an attribute named "Plot" that can discriminate against them (basically being id + 1). It's the attribute used here to label them.

After a table of addresses is geocoded, ArGIS provides information about each geocoded address, among those the "match score" of the candidate to which the address was matched, which ranges from 0 to 100. According to their documentation "The match score is based on how well the locations found in the reference data match with the address data being searched."  It seems intuitive that 100 means an address with the exact name was found in the Address locator and 0 means no such address was found. However, I could not find any information about how exactly this score is calculated, particularly if values are somewhere between the extremes. I this known?  I found the pointer to  in the answer to , but I could not find any information in that paper that would answer the question.

I realize this isn't possible, but I can't see why not, especially if you change the model a little bit so that the balls simply travel through a tube of water on the way up, rather than exactly this model.  Please be clear and detailed.  I've heard explanations like "the balls wouldn't move" but that doesn't do it for me - I really do not see why the balls on the right would not be pulled/pushed up, and the rest of the chain wouldn't continue on. Can I use Facebook's fb:friend-selector in an iframe? Reverse DNS - how to correctly configure for SMTP delivery I started a new service and we need to send emails to our customers (new account confirms, etc).   My server is known as prod01.bidrodeo.com and resolves to 97.107.134.38 .  For reverse DNS, 97.107.134.38 resolves to prod01.bidrodeo.com . However, all our email addresses are in the form of user@bidrodeo.com. Should I make the reverse DNS point to bidrodeo.com instead?   My emails are getting delayed or rejected by certain systems and i am not sure if my reverse DNS is not set up correctly. Ruby can add methods to the Number class and other core types to get effects like this:  1.should_equal(1)   But it seems like Python cannot do this. Is this true? And if so, why? Does it have something to do with the fact that type can't be modified?  Update: Rather than talking about different definitions of monkey patching, I would like to just focus on the example above. I have already concluded that it cannot be done as a few of you have answered. But I would like a more detailed explanation of why it cannot be done, and maybe what feature, if available in Python, would allow this.  To answer some of you: The reason I might want to do this is simply aesthetics/readability.    item.price.should_equal(19.99)   This reads more like English and clearly indicates which is the tested value and which is the expected value, as supposed to:  should_equal(item.price, 19.99)   This concept is what  and some other Ruby frameworks are based on. I have read questions about this, and people say that it is just to include the natbib package and the plainnat style. For some reason my references will not sort alphabetically.

How to align prices in columns when both 2 digit and 4 digit variations of a price exist? Do I need the original discs to install WoW on a new computer? My boyfriend bought the World of Warcraft Battle Chest, Wrath of the Lich King, &amp; Cataclysm. He downloaded them to our previous computer, but now we have a new one and when he took out the first disk from the battle chest he severely scratched it. Anyway, I tried putting in disk #2, and it said I couldn't do it without disk 1 (which is scratched!).  I've recently put in Wrath of the Lich King (it came with 2 CDs), and it said that I haven't downloaded the original and asked me if I wanted to downloaded. I clicked "yes" -- does that mean its downloading WoW &amp; The Burning Crusade? Or do we need to buy it all again?  We just bought the whole set on June of this year... Let $G = (\mathbb{C} - \{0\}, \cdot)$, a subgroup $U = \{x+yi \mid x^2 + y^2 = 1\}$. Use the Fundamental Theorem to show that $G/(\mathbb{R}_{&gt; 0},\cdot)$ is isomorphic to $U$ where $\mathbb{R}_{&gt; 0}$ denotes the positive reals.  I am struggling to find the correct mapping from $G$ to $U$ that results in the the kernel being the nonnegative reals under multiplication. I'm hoping to get help with this mapping then I can show it is a homomorphism and onto and can use the Fundamental Theorem. How can I copy coverart from flac to opus with ffmpeg I am trying to convert some flac files which all have coverart embedded to opus with ffmpeg. All but the coverart gets copied over just fine, but I find myself unable to move the cover over as well. Tried all sorts of -mapmetadata stuff I could find so far, but no luck, the result is always missing the coverart.  While the original .flac reports to have a video stream with the coverart  Duration: 00:02:53.51, start: 0.000000, bitrate: 910 kb/s    Stream #0:0: Audio: flac, 44100 Hz, stereo, s16    Stream #0:1: Video: mjpeg, yuvj420p(pc, bt470bg/unknown/unknown), 500x500 [SAR 1:1 DAR 1:1], 90k tbr, 90k tbn, 90k tbc   the created opus files does not have any graphics:  size=    2815kB time=00:02:53.51 bitrate= 132.9kbits/s speed= 104x video:0kB audio:2793kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 0.811556%   I tried -vcodec copy, -mapmetadata 0, -mapmetadata 0:s:0 so far, with no luck. Doesnt seem to have anything todo with opus, as I have the same problem converting to aac.  So is there a way to get the cover out of the flac file and move it over to the new file in on go using ffmpeg, or do I have to extract it first and then glue it back again later to the new file with extra commands?

App Version: 1.6.6.2 Device: iPhone 6 OS Version: Version 11.0.3 (Build 15A432) We have been asked to prove the above statement through the two sub-proofs:   Firstly we must prove that $e^x$ is increasing and then prove that $\log(x)$ is also an increasing function.   After we are asked to prove that using the delta-epsilion definition of a limit that $\lim_{x \to 0} e^x = 1$.   I have done all of this but still don't see where the instructor is going with this.

For every $n \in \mathbb{N}$, find a function $f$ which is differentiable $n$ times at $0$, but not $n+1$ times. For every $n \in \mathbb{N}$, (in this problem $\mathbb{N}$ starts at $n = 1$) find a function $f$ which is differentiable $n$ times at $0$, but not $n+1$ times.  The function I chose is the following:  $$ f_n(x) = \begin{cases} x^{n+1} &amp;\mbox{if } x \le 0\\ x^{n} &amp;\mbox{if } x &gt; 0 \end{cases} $$  Now I can't think of the best way to prove that $f$ is differentiable  $n$ times at $0$ but not $n+1$ times.
