I’ve recently noticed that many of my posts get edited by new users, and the edits are subsequently approved (often unanimously).  Great, right?  Yes. Except that many of these edits are spurious, or wrong. The first kind irks me somewhat but is tolerable. The second kind, not so much.  Here are two examples from the last day:    – The edit doesn’t invalidate the answer, it’s just completely superfluous. I don’t particularly resent it, I just think it shouldn’t have been approved: that’s not what edits are for.  – The editor apparently confused the words “expect” and “except”. No biggie, but all but one reviewer didn’t notice this.   That’s not review. It’s just clicking “ok”.  I realise that there are already measures in place to catch  reviewers. But they don’t seem to be working particularly well, at least as far as I can tell.  I have no solution. I just wanted to offer this anecdote for consideration.
Already I have lost all hope of looking at late answers etc. It's just a parade of meh. I can't make any kind of intelligent decision because I can't see the other answers to the question, for instance. There's no Looks Good, only Skip, and those feel different to me. So I've been more interested in .  But people keep approving crap while I'm looking at it. Two or three "the post was already approved; please visit to edit" and I'm just "screw this whole thing".  Can we do something like one reject bounces all existing votes: you need three approves in a row? Because a lot of people are stupidly approving and actually driving me away from the queue.    Note this is less about letting bad edits through and more about keeping reviewers motivated.
Chrome S3 Cloudfront: No 'Access-Control-Allow-Origin' header on initial XHR request Can a multi-core processor run multiple processes at the same time? I understand that a multi-core processor can run multiple threads of the same process at the same time using its different cores. Can it also run multiple processes at the same time(each core running a different process)? QM without complex numbers Prove there is an increasing sequence ($s_n$) of points in $S$ such that $\lim s_n = \sup S$. Let $S$ be a bounded set. Prove there is an increasing sequence ($s_n$) of points in $S$ such that $\lim s_n = \sup S$. Note: If $\sup S$ is in $S$, it’s sufficient to define $s_n = \sup S$ for all $n$.  What I have tried so far:  Let $M=\sup S, L = \lim\, s_n,\,|s_n-L|&lt;\epsilon/2$, then $M-\epsilon &lt; L- \epsilon/2 &lt; s_n &lt; M &lt; M+\epsilon$. But I get this based on $M &lt;= \epsilon+L$, because $\epsilon+L$ is an upper bound for $s_n$.   However, as $s_n$ are just points in $S$, so I don't know if it's sufficient to say $M$, which is the $\sup$ of $S$, is smaller than $L+\epsilon$. automatically apply special formatting to selected words in text Should I use a comma in this sentence? I am trying to teach myself punctuation rules. I have this sentence:     The Disney version generally considered both racist and sexist portrayed the female characters in stereotypical roles and presented ethnically diverse characters with stereotypical features.   I think the sentence needs a comma after sexist and before portrayed. I also think it needs a comma after roles because of what I have identified as a coordinating conjunction. I.e.:     The Disney version generally considered both racist and sexist, portrayed the female characters in stereotypical roles, and presented ethnically diverse characters with stereotypical features.   Did I punctuate the sentence correctly? Is this a coordinating conjunction? "Is there" versus "Are there" Are there any questions I should be asking?   Is there any articles available on the subject?   My instinct is that in the two questions above, it should be 'are' as the subjects of the sentences (questions/articles) are plural.  However I also recall being told that the singular 'is' is valid here too, and of course see it very often in usage online, and this has left me a bit unsure.  Update: I have stumbled upon the reason for the confusion.     Is there any water?   Are there any questions?   The sentence structure is the same but of course water is not plural, although it is not singular either. Viruses at this period of time do not fit the current definition of life.   Much of the reasoning behind this is that we currently believe that all life must be made up of cells.  Also, many biologist/scientists say that viruses are not living because all they are is just chemicals carrying out their predefined chemistry.   Has anyone every considered the fact that cells, the supposed building blocks of life, themselves simply only carry out predefined chemical actions? All actions cells carry out are chemically driven, not consciously or spiritually driven. Cells do not make choices, they follow chemical directions present in their DNA and RNA. Viruses act very similarly, following the action transcribed in their DNA or RNA.   How can we really even draw a defined line of what life is? Why should the interface for a Java class be preferred? would report a violation for:  ArrayList&lt;Object&gt; list = new ArrayList&lt;Object&gt;();   The violation was "Avoid using implementation types like 'ArrayList'; use the interface instead".  The following line would correct the violation:  List&lt;Object&gt; list = new ArrayList&lt;Object&gt;();   Why should the latter with List be used instead of ArrayList? When can we interchange “who/which" and "that”? So far I thought the words who and that are usually interchangeable:   There is the man who saw me.  There is the man that saw me.    Both sentences seem fine, who can be replaced with that. But in the following examples:   This is the man to whom I spoke.  This is the man to that I spoke.    The #2 sounds odd, which is why I don’t think it might be correct. The same observation for the words which and that, while   This is the ball which we used today.  This is the ball that we used today.    Seem to be in order and which can be replaced with that. But in the following examples the #2 sounds odd again.   This is the ball with which I scored.  This is the ball with that I scored.    I wonder if there’s any rule regarding the interchangeability of the above mentioned words. While finding escape velocity, does human mass counts as the mass of Earth? Escape velocity depends upon the mass of earth. my doubt is whether human mass adds into it or not? If it add then Earth's escape velocity would be increasing! How can I determine which process owns a hotkey in Windows? Given a hotkey, how can I find which program owns it? Gauge symmetries and elementary particles The  (disclaimer: I don't know this wikipedia entry) is usually mentioned as the reason why gravitons may not be composite particles. I do understand the proof of the theorem, but not the previous conclusion.   The theorem states that in an interacting and Poincare invariant quantum field theory, there are not massless, spin-2 particles unless there exists a gauge symmetry — which makes the energy-momentum tensor non-covariant (actually covariant up to a gauge transformation) under Lorentz transformations in the Fock space. So the immediate conclusion of the theorem is that the existence of a massless, spin-2 particle (like a graviton) requires linearized diffeomorphisms.  My question is: why do linearized diffeomorphisms imply that gravitons are elementary particles? Or, more in general, why  the particle corresponding to a gauge field must be elementary (I know that a gauge symmetry must be exact, but why this implies that the corresponding particle must be elementary?). This is an attempt to write a canonical QA for this issue, as per the Meta post:   I expect it to be periodically edited with the goal of becoming a comprehensive information resource.  I have a MacBook Pro that has a key(Shift, Return,   Command, P, etc.) that doesn’t respond when pressed or is stuck in the down position.    It's possible that my favorite beverage was spilled (or some other liquid damage).  It's also possible that I have no idea what happened.  It was working yesterday and suddenly today it's no longer working.  Is there any way to bypass or remap the key?  Can I  have the system ignore it completely?  (This question can also apply to external USB keyboards or the Bluetooth keyboards) I have a question regarding selections in ArcGIS for Desktop. Assumed I have one layer in ArcMap and I have selected two of five features.   Is it possible to get a list of all selected features by using Python?   It would be fine if there is a way to get one special (or all) attribute(s) of the selected features stored in a list that can be written into a txt file.  Is it possible to do this in ArcGIS for Desktop? Do stars remain electrically neutral? Proving an identity relating to the complex modulus: $z\bar{a}+\bar{z}a \leq 2|a||z|$ Show that $z\bar{a}+\bar{z}a \leq 2|a||z|$  I was able to check this using some examples which is not ideal for a mathematician way of proving a problem/case/theorem. I couldn't generalize it (prove it). I will be glad if I can be given the hint/proof for this problem. Thank you. How to use "fit" to frame the nodes and labels I'm using the fit TikZ library to fit a rectangle around two nodes which include labels. However, the rectangle is only fit around the actual nodes, not about their labels:  \documentclass{article} \usepackage{tikz} \usetikzlibrary{fit}  \begin{document} \begin{tikzpicture}   \node [label=label1,draw] (node1) {Node1}; \node [label=label2,draw] (node2) at (4,2){Node2};  \node[fit=(node1)(node2), draw] {}; \end{tikzpicture} \end{document}     How to fit the rectangle also around the node labels? Checking if array is multidimensional or not? What is the most efficient way to check if an array is a flat array of primitive values or if it is a multidimensional array? Is there any way to do this without actually looping through an array and running is_array() on each of its elements? Suppose that $X_1, \ldots, X_n \sim N(0,1)$ are independent random variables. I am interested in finding a constant C that satisfies:  $$ E\left[\max_{1\leq i\leq n}|X_i|\right] \leq C \sqrt{log\  n} $$  I know one method is to employ the moment generating function trick, then take logs of both sides. However, I was wondering if there exists a more direct method. thanks!
