I'm doing R&amp;D on GeoServer for my project requirement to access JDBC based Database(MapD).  So to do that GeoServer provided some extension for particular database access extension like JDBC based extension sql server,but in my scenario database is another that also have JDBC based driver.  I got github geotools link but didn't get which classes and method used for make extension and  how going on process.  So To make GeoServer extension for JDBC based database, which java classes and method need to change and make jar file to put into lib folder to access database on GeoServer.  So any help me how to do in steps.
In my project requirement to access table data from Mapd Database on GeoServer  Mapd(GPU Based database) Database documentation link:   But in GeoServer provided some extension to connect and access particular database  GeoServer Extension link:    How can I connect MapD databse with geoserver is there any plugin.
I'm using the following command to embed images in my LaTeX document (which is then rendered as PDF)  \newcommand{\img}[4]{   \begin{figure}[!hbt]     \centering       \vspace{1ex}       \includegraphics[width=#2]{images/#1}       \caption[#4]{\label{img.#1} #3}     \vspace{1ex}   \end{figure} }   When creating a href to an image, the viewer jumps to the image caption instead of the top of the image. How do I change my \img command so it still puts the caption below the image but links to it jump to the image itself? Did I "get" (or "take") my degree "from" (or "in") the University of Somewhere? I would like to know what is the preferred way to indicate that I took a degree in some subject while also naming the place where I obtained the degree from:   I got my master's degree from the University of Somewhere; I got my master's degree in the University of Somewhere; I took my master's degree in the University of Somewhere.   I would say that "in" is more suitable to mention the particular subject (a degree in maths, for instance) than to indicate the place, but I still have doubts.  By the way, is it a "master's degree" or a "Master's degree"? R : constraining coefficients and error variance over multiple subsample regressions Could we please be a bit nicer to new users? $G$ solvable $\implies$ composition factors of $G$ are of prime order. I'm trying to prove the equivalency of the following definitions for a finite group, $G$:  (i) $G$ is solvable, i.e. there exists a chain of subgroups $1 = G_0  \trianglelefteq G_1 \trianglelefteq \cdots \trianglelefteq G_s = G $ such that $G_{i+1}/ \ G_i$ is abelian for all $0 \leq i \leq s-1$  (ii) $G$ has a chain of subgroups $1 = H_0  \trianglelefteq H_1 \trianglelefteq \cdots \trianglelefteq H_s = G $ such that $H_{i+1} /\  H_i$ is cyclic for all $0 \leq i \leq s-1$.  (iii) All composition factors of $G$ are of prime order.  (iv) G has a chain of subgroups $1 = N_0  \trianglelefteq N_1 \trianglelefteq \cdots \trianglelefteq N_t = G $ such that each $N_i$ is a normal subgroup of $G$, and $N_{i+1}/ \ N_i$ is abelian for all $0 \leq i \leq t-1$.  It was simple to show that (iii) $\implies$ (ii) and (ii) $\implies$ (i). Now, I'm trying to prove that (i) $\implies$ (iii), and I'm getting stuck.   I know that If $G$ is an abelian simple group, then $|G|$ is prime, so all I need to show is that each $G_{i+1}/ \ G_i$ in the definition of solvable is simple.  If I knew that $1 = G_0  \trianglelefteq G_1 \trianglelefteq \cdots \trianglelefteq G_s = G $ were a composition series, then each $G_{i+1}/ \ G_i$ would be simple by definition. But the definition of solvable doesn't assume a composition series. I know every group has a unique composition series, but I'm not sure how to connect that to the subgroups in the definition of solvable.   More generally, I guess I just don't understand how being abelian connects to being of simple or of prime order.  Any pushes in the right direction would be appreciated! Why would Littlefinger want this person dead? I've noticed an interesting phenomenon in the user interfaces of many famous applications, they're moving away from the glossy complex to a more dull and bare minimum design.  Why the sudden change? It also appears that most of these companies have adopted this design around the same time, was that linked to some new study?  Examples: Python does not find packages installed without Anaconda I'm trying to install kivy for python 3 using apt-get:      sudo apt-get install python3-kivy   And it is installed in      /usr/lib/python3/dist-packages   But, when I tried to load it in python, I get a ModuleNotFoundError      Python 3.6.3 |Anaconda custom (64-bit)| (default, Oct 13 2017, 12:02:49)      [GCC 7.2.0] on linux     Type "help", "copyright", "credits" or "license" for more information.     &gt;&gt;&gt; import kivy     Traceback (most recent call last):       File "&lt;stdin&gt;", line 1, in &lt;module&gt;     ModuleNotFoundError: No module named 'kivy'   When I check the system path from python, I only get packages in Anaconda:      &gt;&gt;&gt; import sys     &gt;&gt;&gt; print('\n'.join(sys.path))      /home/santiago/anaconda3/lib/python36.zip     /home/santiago/anaconda3/lib/python3.6     /home/santiago/anaconda3/lib/python3.6/lib-dynload     /home/santiago/anaconda3/lib/python3.6/site-packages     /home/santiago/anaconda3/lib/python3.6/site-packages/torchvision-0.2.0-py3.6.egg   Is there any way to include the '/usr/lib/python3' path to Anaconda?  Thanks. I am trying to find out how to approach a relief type project. I have a background image and a flat plane mesh to sculpt on, but I actually don´t see any changes looking straight on top.

Forward an invocation of a variadic function in C How can I link to an external resource in a community-friendly way? I would like to help my fellow Stackizens, using material from my blog or other website.  But external links are sometimes viewed as excessive promotion.  From the FAQ:     Be careful, because the community   frowns on overt self-promotion and   tends to vote it down and flag it as   spam. Post good, relevant answers, and   if they happen to be about your   product or website, so be it. However,   you must disclose your affiliation in   your answers. Also, if a huge   percentage of your posts include a   mention of your product or website,   you're probably here for the wrong   reasons.   I have tried posting answers that reference my blog, and I have followed the above rules, but my answers still get flagged as spam.  How can I craft an answer that references my blog, website or other resource, but is still acceptable to the community? Text not very readable on different image backgrounds I've come here seeking for a bit of design help or advice on how I could possibly improve the following:  Like the title says, I'm having a website banner with multiple text displayed on different images as backgrounds. Now, since most of the images are dark, I've set the font color as white. But even then, some of the text is not very readable on a couple of images like:    Since I'm working with CSS, I've tried different options such as:  Adding Text Shadows:    CSS:  text-shadow: 3px 3px 0px #000;  Also tried, creating a semi-transparent box around the text:      I feel the box one looks out of place.  I've created a  for anyone who knows CSS. If not, please feel free to advice me based on your imagination alone.  PS: You could also advice on using a different font if that would help it stand out better.

The future of meta.stackoverflow and meta.stackexchange Historically this site, , has been the place to ask questions about not just Stack Overflow, but the functioning of the entire Stack Exchange (2.0) network, including Area 51 and stackexchange.com and careers.  (Yes, there was a , but that dealt with the old legacy Stack Exchange 1.0 sites. It was deprecated a while ago, and currently redirects here.)  Now that we've gotten many, many months under our belt from the SE 1.0 days, I think it's time that we gave Stack Overflow its own, true per-site meta, and moved the higher level network meta discussions to meta.stackexchange.com.  Over time, it's begun to bug me more and more that requests for Stack Overflow, the site, kind of get buried here on meta.stackoverflow under the avalanche of network issues. Retag requests, synonym requests, things truly specific to Stack Overflow, the site, not the network. This is unfair to our vastly largest and flagship Q&amp;A site, and it's unfair to the Stack Overflow users to mix their requests in with network level concerns.  It's also odd that Stack Overflow is the only network site without a proper, dedicated per-site meta, where its meta has its own reputation system not tied to the parent site in any way.  This is mostly a quirk of history more than anything else, and I believe it is now an appropriate time to split into two sites:   , a proper per-site meta for Stack Overflow with integrated rep , a global network meta with its own reputation system   Yes, this will be painful. But I believe it is a good, necessary, and healthy step both for the future of the network and the future of Stack Overflow.  Some things to discuss:   which questions should be migrated from here to meta.so? Obviously site-specific things like the retag-requests, and perhaps questions with the  tag. Anything that is 100% wholly specific to Stack Overflow and not generalizable to the rest of the network should be moved over. This may be a pretty small, narrow list of questions, and that's OK. Should we do some meta spring cleaning in our transition? Which questions / tags should be blown away as no longer relevant, referring to ancient versions of Stack Overflow or issues that have long since ceased to exist and aren't instructive for any future visitors? Your meta reps will generally be unaffected, except insofar as we delete for spring cleaning, or move site-specific things to meta.so. We still plan to have a distinct reputation system for the new meta.se site, just like here.   I do not have a timeline for this change, that is up to Jarrod and David to decide. It may be months away. However, we feel pretty strongly that this is something that we need to do to clean things up and pave the way for the future -- so I expect it will happen in the next few months, giving us lots of time to decide how we want to do it, per the above.  Update  . Is there a good way to determine the value of magic items in 5e? In 5e, magic items aren't as common or as varied as in older editions, but that also means it is hard to place prices on them.  As DM, NPC's can't really sell a magic item because we don't know the prices for these items. While it is stated that they are rare and usually unpurchasable and unsellable, but I still have to have some basis on what to price them.  So is there a way to find buying and selling prices for magic items in 5e? I am trying to implement the following K-map with a table    AB C     00 01 11 10       ______________     0| 1  0  1  0     1| 0  1  1  0   I implemented it like this:   \begin{table}[htdp] \begin{center} \begin{tabular}{c|c|c|c|c|}  &amp;00 &amp; 01&amp; 11&amp; 10 \\ \hline 0&amp;1&amp;1&amp;1&amp;1\\ 1&amp;0&amp;0&amp;0&amp;0\\ \end{tabular} \end{center} \label{default} \end{table}   However on the top row I have vertical lines that I'd like to not see. I went with this approach because if i was to use a one row with the information so that I wouldn't have to worry about aligning the headings. So is there a way I can get the vertical lines not to appear in the heading row? Do I have to use “do” in any “wh-” question? What did you say?  What you said?   What did you wear? What you wore?    Where did you go? Where you go?    I know that sometimes in English, people do not use “do” in “wh-” questions. I have heard somewhere that people do not use “do” when the answer is a proper noun or a unique thing. Am I right? Are airlines in the EU obligated to provide water for passengers? Why do we say that irreducible representation of Poincare group represents the one-particle state? Only because   Rep is unitary, so saves positive-definite norm (for possibility density), Casimir operators of the group have eigenvalues $m^{2}$ and $m^2s(s + 1)$, so characterizes mass and spin, and It is the representation of the global group of relativistic symmetry,    yes?
