I am using TeXWorks and running pdfLaTeX + MarkeIndex + BibTeX. I made my .bib file with the newest version of JabRef for PC. Here is my MWE:   \documentclass[notitlepage]{article}   \usepackage[backend=biber, style=alphabetic, citestyle=authoryear]{biblatex}  \usepackage{amsfonts} \bibliography{/C:/Users/Ryan Schiller/Kannai} \begin{document}  \printbibliography{} \end{document}   I get the following error:      No pages of output.   Transcript written on "try it.log".      Sorry, but "MiKTeX Compiler Driver" did not succeed.      The log file hopefully contains the information to get MiKTeX going   again:      C:\Users\Ryan   Schiller\AppData\Local\MiKTeX\2.9\miktex\log\texify.log   But as you can see, I do have a .bib file:  So I renamed the document to "tryit" without a space. Then I deleted my aux files. Then in command line I ran pdflatex tryit.tex, pdflatex tryit.tex,biber tryit.tex, pdflatex tryit.tex  But on the first run, I got the error:     LaTeX Warning: Empty bibliography on input line 10. (tryit.aux) LaTeX Warning: There were undefined references. Package biblatex Warning: Please (re)run Biber on the file: (biblatex) tryit (biblatex) and rerun LaTeX afterwards. ) No pages of output. Transcript written on tryit.log   How do I get my references?
I have used quite some time searching for a solution to my compile problem. The document worked fine untill yesterday. After adding some new references, compiling stoped working properly. I have however used latex only for a few months, so the error might be an easy fix.   My error code in the blg file is:    [836] Utils.pm:209&gt; ERROR - BibTeX subsystem:  C:\Users\andre\AppData\Local\Temp\yb9w7ETEpQ\thesisbiblo.bib_16800.utf8,  line 1375, syntax error: found ",", expected one of: number, name (entry  type, key, field, or macro name), end of entry ("}" or ")") or quoted string  ({...} or "...").    I have biber 2.11 and miktex 2.9 and thought it could have been the cache file as suggested in a previous thread with 2.11 versions, but it did not do the trick to delete that either.

Is there any way to "fix this" Difference estimate & confidence intervals for $\chi^2$ test between 2 proportions I am using a chi-sq test between two proportions (). I am using this over the z-test for proportions because I do not think my data is normal.   My question is how do I get the difference (shift) estimate &amp; confidence intervals for this test.   For example,     Data1: 193/252=.77   Data2: 154/227=.68   P-value=.032 (I used the formula in the link above. I will also add my exact code below)  Shift Estimate: I assume its the difference between proportions, ie .77-.68=.09. Is this correct?   Confidence Interval: ??????????????????  Code for generating P-value (matlab):   % Pooled estimate of proportion  p0 = (n1+n2) / (N1+N2); % Expected counts under H0 (null hypothesis)  n10 = N1 * p0;  n20 = N2 * p0; % Chi-square test, by hand  observed = [n1 N1-n1 n2 N2-n2];  expected = [n10 N1-n10 n20 N2-n20];  chi2stat = sum((observed-expected).^2 ./ expected);  p = 1 - chi2cdf(chi2stat,1);  H=0; if(p&lt;.05), H=1; end What does the word treats mean in this context? I don't think it means entertainment, food, drink etc.. Maybe it is an old usage of this word? Does it mean influencing factors or something like that?  This is the first part of the title of the first chapter of the novel "Oliver Twist" by Charles Dickens. The whole title reads:     Treats of the Place Where Oliver Twist was Born and of the Circumstances Attending His Birth Keeping track of programs When I install a simple program it often uses make &amp;&amp; make install and doesn't often even have an uninstall target.  If I wish to upgrade a program, is it standard protocol to assume it just rewrites seamlessly over the old program?  How do I keep track of these programs; do most people just 'fire and forget' and if no uninstall target is given do I have to manually delete everything? How to speed up 4e combat I DM a group of four PC's and even "easy" battles take at least an hour to resolve. Normal encounters take even longer! I want to speed up combat so my players can do more in a session.  I've been trying a lot to speed up combat, we are already using:   Initiative cards that the players keep up 30 second bonus rule: if someone take his turn within 30 seconds, he receives a token. This token can be used to give a +1 on attack or damage, after rolling. Completely removed healing surges Checked all character sheets, they are roughly equal Roll damage and attack at the same time   I even introduced an experienced player, which helped my party to play more strategic, but speed hasn't improved.  Also the party is Lv 8, nearing Lv 9.  This is not an issue of the DM's turn taking too long. My turns take about 60 seconds tops. The 30 second rule helps a lot, most of the the players turns are within or near 30 seconds.   The major issue appears to be the sheer number of rounds, averaging on 25-30 rounds needed to resolve even a "normal" encounter.  What can I change to resolve combat faster?  I'm looking for both 4e solutions, system agnostic and home brew solutions. An example of a norm which can't be generated by an inner product I realize that every inner product defined on a vector space can give rise to a norm on that space.  The converse, apparently is not true.  I'd like an example of a norm which no inner product can generate. Replacing a toilet, when I turn the water valve off there is still water running into toilet? When trying to replace a toilet, the water valve to toilet will not stop water supply even when valve is shut off. I have opened and closed the valve several times but water continues to be supplied to toilet. Fine, the 's math  did in the old pop-up. That makes sense. But this is just silly. Why do I need to be notified that a post I downvoted got deleted?    (The title links next to the red -1s were removed from the screenshot by me. They're present in the real pop-up.)  So I can break out a bottle of the '82 Rothschild? It's especially pointless because there's  that caused the change.  Please don't display the Rep Signal when the change is only due to someone else's deleted posts. I've created a Lightning component to view key details for the Account and Contact lookups from a Case, like so:    The problem is, I have been unable to get field content to render when  using the &lt;force:inputField/&gt; or &lt;force:outputField/&gt; components when I place them inside the markup to style them as cards. I've used &lt;ui:outputText/&gt; as a workaround, but that means I don't get any of the built-in behaviors I would get with the &lt;force:*Field/&gt; components -- like Lightning styling, which means I have to manually do it using SLDS.  This displays the contact name as expected:  &lt;aura:component implements="flexipage:availableForRecordHome,force:hasRecordId" access="global" controller="LightningCaseTestController"&gt;   &lt;aura:handler name="init" value="{!this}" action="{!c.doInit}" /&gt;   &lt;aura:attribute name="recordId" type="Id" /&gt;   &lt;aura:attribute name="contact" type="Contact" default="{sobjectType: 'Contact'}"/&gt;    &lt;force:outputField value="{!v.contact.Name}"/&gt;   &lt;force:inputField value="{!v.contact.Name}"/&gt;  &lt;/aura:component&gt;   This does not:  &lt;aura:component implements="flexipage:availableForRecordHome,force:hasRecordId" access="global" controller="LightningCaseTestController"&gt;   &lt;aura:handler name="init" value="{!this}" action="{!c.doInit}" /&gt;   &lt;aura:attribute name="recordId" type="Id" /&gt;   &lt;aura:attribute name="contact" type="Contact" default="{sobjectType: 'Contact'}"/&gt;    &lt;article&gt;     &lt;force:outputField value="{!v.contact.Name}"/&gt;     &lt;force:inputField value="{!v.contact.Name}"/&gt;   &lt;/article&gt;  &lt;/aura:component&gt;   Basically, it appears that as soon as any markup is placed around the &lt;force:*Field/&gt; tags -- even just a &lt;div&gt; -- they no longer render. Examples in Trailhead and other places all seem to use &lt;ui:outputText/&gt; or &lt;ui:input*/&gt;.  This seems like a lot of extra manual work. Am I missing something?  Update: it only fails when the component is included in a Lightning page -- such as the record detail page -- from Lightning App Builder. If I add it to a simple Lightning app, it works:  &lt;aura:application &gt;     &lt;c:LightningCaseTest recordId="SOMECASEID" /&gt; &lt;/aura:application&gt;   So it appears to be a bug? I'm trying to build a datapack that lets you craft xp bottles from glass bottles at the expense of 7 xp per bottle (because they drop 3 to 11 xp so the average is 7). I have almost everything working except for a check for if they have too little xp. If they have 7 or less xp, I would like to remove one bottle of enchanting from their inventory and give them one glass bottle, because the function for removing xp is called after they've crafted one and a scoreboard has counted it. My remove function currently looks like this:  #create dummy scoreboard to multiply bottles crafted by seven to get xp to be removed scoreboard objectives add 7xp dummy scoreboard players set @s 7xp -7 scoreboard players operation @s xpCrafted *= @s 7xp  #how do I get the value in xpCrafted into the command to remove xp? xp add @s -7 points  #cleanup scoreboard players reset xpCrafted scoreboard players reset 7xp scoreboard players set @e xpCrafted 0 scoreboard objectives remove 7xp   And my tick function like this:  execute as @e[scores={xpCrafted=1..}] at @s run function craft_xp:removexp   As the inline comment says, how do I get that value in xpCrafted into my xp removing command, and also how should I check to make sure the player has enough xp for the operation in the tick command (or elsewhere)? Presumably I would run a different command to remove the extra bottle if they didn't have enough xp, but I don't know how because there doesn't seem to be any type of if/else structure in commands. Finally, should a question like this be in two different questions or is one ok on this forum? What is "Go" in cribbage? I've played a fair bit of cribbage, but I've never heard of scoring one point for "Go" (as mentioned in this other question: ).  What is it, and what impact does it have on the game? Imagine you're teaching a first course on quantum mechanics in which your students are well-versed in classical mechanics, but have never seen any quantum before.  How would you motivate the subject and convince your students that in fact classical mechanics cannot explain the real world and that quantum mechanics, given your knowledge of classical mechanics, is the most obvious alternative to try?  If you sit down and think about it, the idea that the state of a system, instead of being specified by the finitely many particles' position and momentum, is now described by an element of some abstract (rigged) Hilbert space and that the observables correspond to self-adjoint operators on the space of states is not at all obvious.  Why should this be the case, or at least, why might we expect this to be the case?   Then there is the issue of measurement which is even more difficult to motivate.  In the usual formulation of quantum mechanics, we assume that, given a state $|\psi \rangle$ and an observable $A$, the probability of measuring a value between $a$ and $a+da$ is given by $|\langle a|\psi \rangle |^2da$ (and furthermore, if $a$ is not an eigenvalue of $A$, then the probability of measuring a value in this interval is $0$).  How would you convince your students that this had to be the case?  I have thought about this question of motivation for a couple of years now, and so far, the only answers I've come up with are incomplete, not entirely satisfactory, and seem to be much more non-trivial than I feel they should be.  So, what do you guys think?  Can you motivate the usual formulation of quantum mechanics using only classical mechanics and minimal appeal to experimental results?  Note that, at some point, you will have to make reference to experiment.  After all, this is the reason why we needed to develop quantum mechanics.  In principle, we could just say "The Born Rule is true because its experimentally verified.", but I find this particularly unsatisfying.  I think we can do better.  Thus, I would ask that when you do invoke the results of an experiment, you do so to only justify fundamental truths, by which I mean something that can not itself just be explained in terms of more theory.  You might say that my conjecture is that the Born Rule is not a fundamental truth in this sense, but can instead be explained by more fundamental theory, which itself is justified via experiment.  Edit:  To clarify, I will try to make use of a much simpler example.  In an ideal gas, if you fix the volume, then the temperature is proportional to pressure.  So we may ask "Why?".  You could say "Well, because experiment.", or alternatively you could say "It is a trivial corollary of the ideal gas law.".  If you choose the latter, you can then ask why that is true.  Once again, you can just say "Because experiment." or you could try to prove it using more fundamental physical truths (using the kinetic theory of gases, for example).  The objective, then, is to come up with the most fundamental physical truths, prove everything else we know in terms of those, and then verify the fundamental physical truths via experiment.  And in this particular case, the objective is to do this with quantum mechanics. On Stack Exchange, users may gain a certain level of reputation.  What does reputation do?

I am interested in not too basic techniques (which I can more or less figure out by myself), which on the other hand give good results, without the need to be an expert pro. In the PHP manual, to show the syntax for functions with optional parameters, they use brackets around each set of dependent optional parameter. For example, for the  function, the manual reads:  string date ( string $format [, int $timestamp = time() ] )   Where $timestamp is an optional parameter, and when left blank it defaults to the  function's return value.  How do you go about creating optional parameters like this when defining a custom function in PHP? Which computer science / programming Stack Exchange sites do I post on? There seems to be more than a few computer science/programming Stack Exchange networks (is that the correct term?). Stack Overflow, being the first, has by far the most users, questions, and answers.  What is the reasoning for creating the others, and are there clear guidelines for which kinds of questions should be posted? I can see a large amount of potential overflow, many cases of people not getting a good answer to their question, because the person who has the answer isn't browsing that particular network at the moment.  I understand that they were probably created for organizational purposes, but wouldn't it almost make more sense to just have them as categories under Stack Overflow, keep them separated but still connected, instead of making people have to create multiple 'account's, one for each network?  I am sure there was a very good reason to break them up, but as someone that is new to SE, it can be somewhat intimidating to decide which one to post in to ensure you get a good answer. For example, if I am a computer science student, my first instinct might to be to post in the computer science network, until I see that it literally has 1% of the users as the Stack Overflow network, which still seems to be for programming/computer science related questions.  So my second instinct would then to be to post it into the Stack&nbsp;Overflow site on the basis that I have a significantly higher chance of my question being seen and getting a good answer. Then I notice that there is also a 'programmers' network, and I don't even begin to know where that fits in. I, and I am assuming most people, will probably just post on Stack&nbsp;Overflow to be safe.  My question is, other than the short little description blurb of each one, is there a clear cut set of guidelines which what each network is intended for, what kinds of questions should go to each one, and is anything being done to encourage people to post in these newer, smaller (more specialized?) networks as opposed to just posting in big daddy Stack Overflow?  Now again, this is for computer science/programming/"why isn't this code doing what I want?" related questions, I am not saying that if I had a question about Linux or WordPress or something I would have the same confusion. How exactly does a  work?  This is an extremely broad question. What code keeps things bouncing against each other, what code makes the player walk into a wall instead of walk through the wall? How does the code constantly refresh the players position and objects position to keep gravity and collision working as it should?  If you don't know what a collision engine is, basically it's generally used in  to make the player acutally hit walls and the like. There's the 2D type and the 3D type, but they all accomplish the same thing: collision.  So, what keeps a collision engine ticking?
