How to read a raster value table (VAT) in QGIS? By default, QGIS does not seem to recognize "Value Tables" (VAT) the way ArcGIS does.  So far I cannot find a way to represent the pixel values discretely, or apply a "legend" to the layer. Is there something that can be done to associate the VAT with the raster in QGIS? Ultimately I'd like to symbolize and see the joined values when I use the "Identify" tool on a pixel?  For example, I've downloaded a landcover GeoTIFF from the NRCS that contains a single "Pixel Value" field, which represents the type of landcover.  In addition to the GeoTIFF, the authors included a "Value table" (&lt;filename&gt;.vat.dbf), which essentially is "joined" to the raster to give a plain English description of the "Pixel Value", as well as RGB values.  There are 17 discrete values in the VAT, but a small sample looks like this:   Value   Count   Red Green   Blue    Land_Cover 0   299079  0.00000000000   0.00000000000   0.00000000000   Unclassified 11  3896533 0.27843137255   0.41960784314   0.62745098039   Open Water 12  86735   0.81960784314   0.86666666667   0.97647058824   Perennial Snow/Ice 21  4527275 0.86666666667   0.78823529412   0.78823529412   Developed, Open Space   This data can be downloaded from the "National Land Cover Dataset by State" at
Accessing raster attribute table in QGIS? I have some Python code that makes Raster Attribute Tables for GeoTiffs using GDAL.    In ArcGIS I can see these attribute tables fine and they behave how I like (as classifications) but in QGIS the whole concept of an attribute table seems to be missing.    Is there any way to access a RAT in QGIS?
Helical motion of charged particle in external magnetic field What do I need in a camera to take non-blurry photos of a fast-moving child? I'm a mom who is obsessed with taking photos of my now 2 year old daughter.  I currently have a Nikon j1 which I like, but I find the shutter speed is still a bit slow and when you're trying to take photos of a speedy little girl, I end up with a lot of blurry images.  So I'm looking for a camera with a very fast shutter speed that will allow me to take good photos of a very fast moving child.  Also that can take photos in low light. I've been looking at the canon eos rebel but I'm not sure. Would like it to be able to take videos as well. Any advice? Let $n$ be a positive integer. Show that the matrix  $$\begin{pmatrix} 1 &amp; 1/2 &amp; 1/3 &amp; \cdots &amp; 1/n \\ 1/2 &amp; 1/3 &amp; 1/4 &amp; \cdots &amp; 1/(n+1) \\ \vdots &amp; \vdots &amp;  \vdots &amp; \ddots &amp; \vdots\\ 1/n &amp; 1/(n+1) &amp; 1/(n+2) &amp; \cdots &amp; 1/(2n-1) \end{pmatrix}$$  is invertible and all the entries of its inverse are integers. This is an exercise in Hoffman and Kunze's linear algebra book. Any hints will be appreciated! Problem with >> inside of \tt I have an inline code example with a nested Java generic declaration, using the typewriter typeface. However, the closing &gt;&gt; is rendering as a black box. A cursory Google search suggested $&gt;&gt;$, but this removes the typewriter font. Using \textgreater in place of the actual &gt; also encounters the same problem. Here is the offending snippet:  ...declaration {\tt List&lt;Map&lt;Integer, String&gt;&gt;} is...   Any ideas? We know that the addition and multiplication operators are both commutative, and the exponentiation operator is not.  My question is why.  As background there are plenty of mathematical schemes that can be used to define these operators. One of these is   where $H_0(a,b) = b+1$   (successor op) $H_1(a,b) = a+b$   (addition op) $H_2(a,b) = ab $   (multiplication op) $H_3(a,b) = a^b$   (exponentiation op) $H_4(a,b) = a\uparrow \uparrow b$   (tetration op: $a^{(a^{(...a)})}$ nested $b$ times ) etc.    Here it is not obvious to me why $H_1(a,b)=H_1(b,a)$ and $H_2(a,b)=H_2(b,a)$ but not $H_3(a,b)=H_3(b,a)$  Can anyone explain why this symmetry breaks, in a reasonably intuitive fashion?  Thanks. I just signed up, a day or two ago, and I've received a notification that there's something in my inbox.  Unfortunately, my email client isn't able to show me a link to my Inbox, or the message, because of the format of the email.  I normally use the email address that I gave when I signed up, just with MailWasher, which is intended to safely preview emails, as plain text, to decide whether or not to open them in a normal HTML email client.  I would be nice if that email contained a link to my inbox, which could be shown in MailWasher.  In order to collect that email in a normal email client, I'd also have to collect or delete all the other emails sent to that address.  I'm not entirely clear what's been done in that email to stop MailWasher seeing the link.  I can see a link to leave feedback, and one to unsubscribe, but not one to check my inbox.  Sure, I can live without one, but those emails would be a lot more useful to me if I could just click a link to go to my Inbox. Find the area of largest rectangle that can be inscribed in an ellipse The actual problem reads:      Find the area of the largest rectangle that can be inscribed in the ellipse    $$\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1.$$   I got as far as coming up with the equation for the area to be $A=4xy$ but then when trying to find the derivative I don't think I'm doing it right. On iPhone it's very easy to clone an app (running multiple copies of the app on the same device); e.g.:    Is it possible to do this on Android? mysqli::query(): Couldn't fetch mysqli Show that $\sqrt{4 + 2\sqrt{3}} - \sqrt{3}$ is rational. Dictionary definitions  often seem to use the terms sentience, awareness, and consciousness as if they are synonymous with each other. Is this really the case? If not, how do they differ? Some books suggest that sentience and awareness are simply facets of the larger concept of consciousness. It’s a story of a female protagonist who has a harsh life. Just as she is about to die, she time travels back into her young self. To avoid the future she already lived, she decides to gets strong by learning swordsmanship. After a while, she joins the army under the command of a prince who wears an eye patch. She is quite OP, and helps the prince. It was kind of a medieval setting manga, with dukes and earls and count types. Time is when the use of sword and magic is prominent. Clock shows wrong time after switching from Ubuntu to Windows 10 I have dual booted Windows 10 and Ubuntu 16.04 in UEFI mode (secure boot off). My time in BIOS is correct.  When I boot into Ubuntu and then boot into Windows 10, it shows the wrong time. I have to correct it manually or by the internet in Windows 10, and when I reboot into Windows 10 then it is not a problem. The clock will show the correct time. And then when I reboot to Linux the clock is correct, but switching back to Windows 10 the clock messes up again. I am trying to show $$\lim_{n\rightarrow \infty} \int_{[0,1]^n} \frac{|x|}{\sqrt{n}}dx=\frac{1}{\sqrt{3}}$$ where $[0,1]^n$ is the unit cube in $\mathbb{R}^n$. I would appreciate any hint. Using same modulus for RSA I know that there exist some attack when using same modulus.      But with a little modification, $m$ is the plain-text $N$ is the RSA modulus $r_1, r_2$ is the random padding $e, s$ is the public exponent $C_e, C_s$ is the cipher-text  encrypt as follow $$С_e = (m + r_1)^e   \bmod N$$ $$С_s = (m + r_2)^s   \bmod N$$  If attacker only knows $C_e, C_s, r_1, r_2, e, s, N$. Is it possible to know $m$?  It seems the  does not work? Expressing hourly temporal recurrence What is the most idiomatic way to put into words a situation where a recurring event happens every hour at a certain minute. For example, consider that some event takes place at the tenth minute of each hour: 0:10AM, 1:10AM, 2:10AM, ...  My first ideas were "every hour at the tenth minute" or "every hour at minute 10". Are these options idiomatic and if not, what would be an idiomatic way of expressing this matter?

I've gotten a lot of answers to this question, but they are all generic and generally not very useful.  None of the tutorials talk about aspect ratio and dealing with mobile devices and there are a zillion ways to do it, all seem to have gotcha's and flaws.  I really would love to know what successful games have used to handle different aspect ratios on iOS and Android without making a zillion different sized assets.  I am strictly speaking mobile, not desktop, specifically with Unity and I don't care about the UI, I only care about the gameplay canvas.  Issues I have in mind is when there are key things that have to be in certain places and cannot fall off the screen.  Using black bars on top or bottom is unacceptable these days.
