Here is a situation I am in, and I am unsure of how to address it:  I asked a question (on Startups), and two people both work pretty hard to create good answers.  Neither answer is, in my view, complete, but taken together, they answer the question very well.  My question is, how can I reward the responders and indicate to future page visitors that both answers must be read?  I am sorry to ask such a basic question here, but I cannot find guidelines that outline principles that would apply here.  Thanks in advance.  Edit: Ironically, I ended up in exactly the same situation here.  Thanks to Bart and Andy.  (They got upvotes)
I'm kind of curious what kinds of criteria other people go through when selecting the correct answer to their questions.  Here's what I consider when selecting the answer to my question:   Is the answer objective?  It's easy to pick out biased answers.  Usually they involve a statement along the lines of "x sucks, you should ALWAYS use y." Do other members seem to support the answer?  Has it gotten a significant number of +1 posts or has it been voted up a number of times? Is the answer the most thorough?  Does it have an example?   With that said, there are a couple of BAD reasons to choose an answer in my opinion:   The answer is what you want to hear.  My biggest pet peeve is when somebody asks what ostensibly appears to be a valid question, but is really just a thinly veiled attempt to get someone to agree with them.  Thus, the question usually ends up showing a certain bias.  And guess which answer gets selected?  The one that confirms that bias. Nobody posted a better answer.  If you don't see a good enough answer, don't select one.   I'm sure there are a few things I'm leaving out, plus some of what I've said may be arguable.  What is everyone else's take on this?
Preface:  An axis plotted with  is usually using the current math font for its ticklabels. But if they are overwritten by e.g. xticklabels={-8,-6,...,8} then the current text font is used. Also an axis label ylabel={Y} would be in text font unless put explicitly in math mode ylabel={$Y$}. However it would be nice, if  one hadn't to do so.   Question:  I'm aiming to ensure that pgfplots always uses the current math font. But please assume that the classic font commands like \rmfamily are screwed up by the corporate design I'm supposed to use, e.g. assume: \renewcommand{\rmdefault}{\sfdefault}  It works if I explicitly define a font  \newcommand{\pgfmathfont}{\fontfamily{pxfonts}\selectfont}   and pass it to pgfplots together with assume math mode=true:  \begin{axis}[ font = \pgfmathfont,  tick label style={/pgf/number format/assume math mode=true} ]   But it requires that I insert the name of the current math font. How can I do that automatically? How to get the currently used math font to insert it into the macro?    MWE  \documentclass{beamer}  \usetheme{Warsaw} \usefonttheme{professionalfonts} \usepackage{pxfonts} \usepackage{pgfplots}  % screwed up by Corporate Design \renewcommand{\rmdefault}{\sfdefault}  % I'd like this line to be generic! \newcommand{\pgfmathfont}{\fontfamily{pxfonts}\selectfont} %           put current math font here   X  \begin{document}  \begin{frame}  This is a basic equation:    \[ x + y = 42\]  \begin{tikzpicture}     \begin{axis}[ %   font = \rmfamily, % makes no sense here     font = \pgfmathfont,      xlabel={$x$-label: I want to be in math font!},     ylabel={Y},     xtick={-4,-3,...,4},     xticklabels={-8,-6,...,8}, %   xticklabels={$-8$,$-6$,...,$8$}, % does not work     tick label style={/pgf/number format/assume math mode=true}     ]      \addplot {x^2};      \end{axis} \end{tikzpicture}  \end{frame}  \end{document}     Everything related to  is no option at all!  Thank you! Nullable type issue with ?: Conditional Operator Could someone explain why this works in C#.NET 2.0:      Nullable&lt;DateTime&gt; foo;     if (true)         foo = null;     else         foo = new DateTime(0);   ...but this doesn't:      Nullable&lt;DateTime&gt; foo;     foo = true ? null : new DateTime(0);   The latter form gives me an compile error "Type of conditional expression cannot be determined because there is no implicit conversion between '&lt;null&gt;' and 'System.DateTime'."  Not that I can't use the former, but the second style is more consistent with the rest of my code. PDF upload silently fails I dunno since when, but upload of PDF images fails, this hurts especially on tex.SE.  Could this be an effect of an updated /etc/ImageMagick-6/policy.xml on the imgur server?  At least on my Ubuntu 18.04 LTS machine, this file was modified two weeks ago. Double Factorial: Number of possibilities to partition a set of $2n$ items into $n$ pairs I know that the partition of $2n$ items into $n$ pairs has something to do with double factorial, but I am not sure how many possibilities we exactly have.   We can choose such a partition into pairs by first choosing $n$ elements to be in one half and the remaining $n$ in the other half, which gives ${{2n} \choose n}$ possibilities. Then we can take a permutation of both sets and match them accordingly.   This gives $${{2n} \choose n} n! n!=\frac{(2n)! n! n!}{n! n!}=(2n)!$$ possibilities. But with this we overcount, since we do not want the pairs to be ordered. Each of the $n$ pairs is counted twice, wherefore we have to divide by 2 for every pair, hence $\frac{(2n)!}{2^n}$?   Well, another possiblity to do that is just to iteratively pick $2$ elements among the remaining ones, which gives ${{2n} \choose 2} {{2n-2} \choose 2} \dotsb {4 \choose 2}$  I am not sure, but I do not think that this is the same and also, I do not see the connection to double factorial. Would be very glad if you could help me with these 3 possiblities.   Thank you. A reward becomes a penalty if I am working to build a reinforcement agent with DQN. The agent would be able to place buy and sell orders for a day trading purpose. I am facing a little problem with that project. The question is "how to tell the agent to maximize the profit and avoid the transaction where the profit is less than 100$".  I want to maximize the profit inside a trading day and avoid to place the pair (limit buy order, limit sell order) if the profit on that transaction is less than 100$. The idea here is to avoid the little noisy movements. Instead, I prefer long beautiful profitable movements. Be aware that I thought using the "Profit &amp; Loss" as the reward.  "I want the minimal profit per transaction to be 100$" ==> It seems this is not something that is enforceable. I can train the agent to maximize profit per transaction, but how that profit is cannot be ensured.  At the beginning, I wanted to tell the agent, if the profit of a transaction is 50 dollars, I will remove 100 dollars, then It becomes a penalty of 50 dollars for the agent. I thought it was a great way to tell the agent to not place a limit buy order if you are not sure it will give us a minimal profit of 100$. It seems that all I would be doing there is simply shifting the value of the reward. The agent only cares about maximizing the sum of rewards and not taking care of individual transactions.   How to tell the agent to maximize the profit and avoid the transaction where the profit is less than 100$? With that strategy, what guarantee that the agent will never make a buy/sell decision that results in less than 100 dollars profit? Does the sum of reward - # transaction * 100 can be a solution? Can the Earth's magnetic field be used to generate electricity? Is FFmpeg missing from the official repositories in 14.04? What are the prerequisites for studying mathematical logic? I am looking to study mathematical logic, however, I find that introductory books are very daunting, which kind of disheartens me. You see, slowly but surely, I started to realize that the maths which I have learned did not just pop out of thin air, but is a collection of systems, which must of been developed via some other system, i.e, maths did not develop itself.  So I began to look into the origins of mathematics, and read that it was developed via a type of logic, which exists sort of by 'default', via a set of axioms, and then of course I looked up the definition of axioms.   So given that I'd be studying a type of logic whose origins are self evident axioms, naturally I believed there would be no prerequisites. However, in looking up mathematical logic, I have come across things such as Boolean algebra, sets, first order logic, some other type of logic, called 'traditional logic', as well as references to a sort of calculus, though not in a mathematical sense, I think.  So all in all, I am trying to develop a type of mental spider web, and I am trying to find out the strands which lye at the absolute bounds so that I may learn this mystique logic. Though I have no idea where to start.  Side note: This is the book I have started reading:   Credit goes to Wolfgang Rautenberg. I did a bit of math at school and it seems like an easy one - what am I missing?  $$n\times m = \underbrace{n+n+\cdots +n}_{m\text{ times}}$$  $$\quad n\times 0 = \underbrace{0 + 0 + \cdots+ 0}_{n\text{ times}} = 0$$  (i.e add $0$ to $0$ as many times as you like, result is $0$)  So I thought an infinite number of $0$'s cannot be anything but $0$? But someone claims different but couldn't offer a reasonable explanation why. Google results seemed a bit iffy on the subject - hopefully this question will change that. How is the skillset of an evolution being chosen? You may already know that if you catch two Pidgeys, they may have a different skillset.  I've also seen that evolving them from different skillsets will also create Pidgeottos with different skillsets.  Are those skills chosen randomly or do they follow a specific pattern? (Like Pidgey pattern 1 will always evolve into Pidgeotto pattern 1.)  If they are specific, is there a website to check for them? I was very inspired by Michio Kaku's  on the possibilities of quantum computing and also listening to Talia Gershon's  on it.   As I come from a business &amp; analytics background, what materials can I begin exploring to prepare to learn more about the field of quantum computing? Eg. what would I need to study to understand Peter Shor's algorithm,  on physics, etc. Skip certain tables with mysqldump Is it possible to turn off the Two-Factor Authentication for an Apple ID?

Using a transistor as a switch I am attaching a motor to an ATmega32 chip. I want to build an H-bridge but before doing that, I want to control the motor using the chip. I bought few NPN Transistors from RadioShack. I have 5V running though the breadboard. I attached Vcc to the Collector, Base to the Pin, and Emitter to the motor. And other wire of motor is hooked up to Ground. Unfortunately, the power coming out of the transistor is too low, the motor is barely moving (As opposed to when I hook up my motor straight to 5V). What is wrong? Do I need a different transistor or is my setup wrong? If it is the transistor, can you please recommend the right one, I am not too good at those. I am trying to create Thiessen (Voronoi) polygons, based on points within a defined shapefile extent. The output should be inclusive to the feature.  The output I receive now is the rectangular area around the selected points.    Steps I am using: 1. select points of interest (inside and outside spatial extent) 2. set primary display field to FID (aka:ObjectID) 3. Environment… > Set 'Analysis Mask' to shapefile with feature (in this case, a watershed)  Now here is where the problem starts. I have a set of instructions for arc 9.3, but I am now operating on ArcGIS 10 (Spatial Analyst installed &amp; activated).

The first image is an example.  The output does not need to be exact.  wiki: how to decode this JSON string? Configuring auto-completion with TeXstudio TeXstudio does a pretty good job with autocompletion. For example, when I type \eqref{, it already comes with suggestions, see the example below.    However, suppose that I don't want to use \eqref but a customized command using newcommand (I do this so that I can quickly switch to different styles, e.g., some for journals/conferences "Eq. (1)" is needed, whereas sometimes "(1)" suffices). In this case, TeXstudio does not do the auto-completion, see the example below.    Is it possible to configure TeXstudio such that it does the auto-completion for custom commands that require a reference?  Note that one option is to redefine \eqref using \renewcommand, but I'm looking for another way so that I can use if for many more commands, not just for \eqref.
