Highlight citations of works a specific author contributed to

I'm thinking a solution should exist already, but I'm unable to find it... so, how could I highlight citations to a work a specific author contributed to?  It's a bit like printing the name of a certain author in bold in the bibliography, but this doesn't work in citations where the author one wants to highlight is hidden in the "et al."  For highlighting an author in the bibliography, I use  with the \boldname command.   The highlighted author's name might have non-standard characters, so I use a silly example author, Därwin. The behaviour I want would be like this:   Where to start? Add a keyword and change all cite commands by calling \renewbibmacro*{cite}{...}? And what to put there ?  Here's a MWE, I haven't really done anything, but at least it should show the options I'm using (for the sake of conciseness, I left the \boldname definition out, but I could add it if it is relevant).   \documentclass{article}  \usepackage[latin9]{inputenc}   \usepackage[style=authoryear-comp,natbib=true,%  minbibnames=15,%  maxbibnames=15,%  backend=biber]{biblatex}  \usepackage{filecontents}  \begin{filecontents}{\jobname.bib}  @Book{Darwin.84,    author =      {C.

As in the question I have to show that $$\sum_{j=0}^n z^j=\frac{1-z^{n+1}}{1-z}$$ So if we suppose that the above is true then clearly \begin{align}(1-z)(1+z+z^2+\dots+z^n)&=(1-z)+(z-z^2)+\dots+(z^{n-1}-z^n)+(z^n-z^{n+1})\\&=1-z^{n+1}\end{align} as required. But what if I didn't know the right hand side of this equation? How would one work it out just from the sum on the LHS? Thanks for the help.

Why $g$-force increase with radius and centrifugal force decreases?

Trying to understand the 2 formulas and the relations between radius. Common sense will tell me that centrifugal force increases while we are on a curve with a short angle , as newtons law formula suggests, but checking g-force formula it is directly proportional to radius. A bit confuse on which one should be used on centrifugal fluids. What happens to rotating fluids with increasing radius and same rpm or angular velocity, and what happens with fluids with decreasing radius and same rpm or angulsr velicity.


How do completely empty columns in a large table affect performance?

I have 400 million rows in a Postgres db, and the table has 18 columns:  id serial NOT NULL, a integer, b integer, c integer, d smallint, e timestamp without time zone, f smallint, g timestamp without time zone, h integer, i timestamp without time zone, j integer, k character varying(32), l integer, m smallint, n smallint, o character varying(36), p character varying(100), q character varying(100)   Columns e, k, and n are all NULL, they do not store any values at all and are completely useless at this point. They were part of the original design, but never removed.  Edit - most of the other columns are non-NULL.  Questions:   How can I calculate the impact this has on storage? Is it equal to size of column * # of rows ?  Will dropping these empty columns noticeably improve performance for this table? Would the page cache be able to fit more rows?

Two synchronised clocks accelerated perpendicular to Earth's gravitational field

If I have two synchronized (at the station while waiting for me) clocks on a train, one at front and the other one at back, and I start to accelerate the train perpendicular to Earth's gravitational field then do those clocks go out-of-sync? Say, I accelerate at rate 0.1 m/s^2 till the speed equals 20 m/s and the distance between the clocks is 100 m.  Are those clocks out-of-sync when I travel comfortably after the acceleration?  Edit: Using gravitational time dilation for solving the problem sounds odd when I'm not accelerating along a gravitational field.  Edit 2: If I accelerated perpendicularly to a gravitational field I should have, according to the equivalence principle, experienced out-of-sync for my clocks. Does there exist any experimental evidence for the phenomenon? Theory isn't a proof.

Biber and traditional alpha citation style

Beacuse of Bibtex issues with UTF8 characters, I switched to using BibLaTex in conjunction with Biber. I installed the  package to get traditional citation styles.  However, even by using the package, alpha stlye differes slightly from the original one.

Which Sheppard did McKay refer to in S05E19

I'm going to assume enough time has passed that the following is not considered a spoiler:  In the second-to-last episode of Stargate Atlantis, we see an alternate universe where Sheppard is a detective.  In the middle of the episode, McKay questions Sheppard as part of an investigation. McKay then says, "You know, I once met another version of you. He was very different."  What exactly is he referring to? As far as I remember, Rodney McKay said he knew his Sheppard when he traveled between universes, so it can't be this one. Which is it?


I was reading the article Turning Points: A meeting with Enrico Fermi by Freeman Dyson (available e.g. ), and I had a question about Dyson's use of the term 'arbitrary parameter'. More specifically Dyson relates the following interaction:     “There are two ways of doing calculations in theoretical physics”, [Fermi] said. “One way, and this is the way I prefer, is to have a clear physical picture of the process that you are calculating. The other way is to have a precise and self-consistent mathematical formalism. You have neither.”    Dyson then counters that his calculations match the Fermi's experiment, to which Fermi replies (emphasis mine)     “How many arbitrary parameters did you use for your calculations?”       I thought for a moment about our cut-off procedures and said, “Four.” He said, “I remember my friend Johnny von Neumann used to say, with four parameters I can fit an elephant, and with five I can make him wiggle his trunk.” With that, the conversation was over.   So what exactly is an arbitrary parameter in a physics calculation?


When $b$ is prime and $a>0$ is any integer: $$(1/a)\pmod b \equiv a^{b-2}\pmod b$$  Can somebody explain me how this equation holds true in number theory. Someone told me that it can be proven through Euler's theorem, but how?


Playing with mental blocks; one-armed protagonist discovers an engine that spins

SF novel which starts with a one-armed main character, who is very strong, out riding his horse and finds a donut shaped engine.  He proceeds to dismount by grabbing the saddle horn with his one hand and lifting himself out of the saddle to investigate.   After an interesting result from jamming a branch in the donut hole he takes it to a shed to investigate.    I can't remember the title or author.  Remember more story if needed although the opening scene is striking enough that I suspect more isn't needed.


How to determine the base weapon damage for weapons that exceed the size table (specifically the exceptional case of Butchering Axe)?

So I am playing a barbarian wielding a . Last night it happened that by some glory magic my human (medium sized) barbarian was being enlarged letting his terrifying weapon become even more devastating.  So we checked the rulebook for what its new base damage would be. But unfortunately, the table ends at medium sized 2d6 becoming 3d6.  But since the  at medium size has already a weapon damage of 3d6, we tried to make out the pattern of the table which at that point was ambiguous (for us at least) we thought it either might be 4d6 following the increase from 2d6 to 3d6, or it might be 3d10 due to the steps at lower base damage weapons.  So the question is:  What is the weapons damage to be rolled here and by which pattern would this be identified for weapons exceeding the books printed table?  Please take note that this is a specific case, that differs from the duplicate, as the comments in the accepted answer mention the Butchering Axe differs from the usual determination, but don't mention in how far this is different. Hence that other post does NOT answer it for the specific case of Butchering Axe.


pdflatex fails within Emacs.app, but works in terminal

LaTeX rookie here.   I'm running OS X 10.7 with Emacs 24, Auctex 11.86 and TexLive 2011 via MacTex.   When i run LaTeX through Emacs in the terminal it outputs my test.tex as test.pdf just fine.   However, when i run the same file through Auctex in Emacs.app it fails and i'm given:  LaTex: problems after [0] pages'   and the output reads  Running `LaTeX' on `test2' with ``pdflatex -synctex=1  -interaction=nonstopmode "\input" test2.tex'' /bin/sh: pdflatex: command not found   I've been googling this and know this is a fairly common problem, but for the life of me I haven't been able to implement a fix. From what i've read it seems Emacs has a different PATH than terminal, no? Can someone please explain to me how to fix the PATH or environment variable (i'm not sure which) so that Emacs can find pdflatex. Is there something I need to change in my ~/.emacs ?  thanks, any help is appreciated.

Experiment: Review-needed indicator logic for sites that sometimes have empty queues

One of the more common bits of feedback when we  was that some sites would prefer to have an indication when there are any outstanding reviews available. So we are trying an experiment with an "inbox zero" review indicator. This would mean:  The review indicator lights up whenever there is at least one item in any queue.  There's no concept of the "danger threshold"; if there's even one item in a queue, it's marked with a red dot.    Clearly, this logic would be annoying for , so we've made it a site setting. We're going to test it out on a handful of sites to see how people respond to it:            One final thing: you will be notified even when you cannot complete a review task (for anyone who can see the review queue - 500+ reputation). In particular, people who do not have enough reputation to handle items all the queues will be notified of items in queues they can't access. This is the next thing we are working to fix. If too many people are frustrated by this situation, we'll pause the test until that problem is fixed. It'll also light up even after you've finished all the review tasks available to you, which is a much harder problem for us to fix. The goal of this experiment is to test whether aggressively notifying users can make "inbox zero" a possibility for sites that are close.


Good Night ... Here I am editing the question and explaining the purpose of the same ... Mathematics course, and I love this science, I am very curious, and these days, studying a book of calculus found in (book from the library of the University) a sheet full of challenges, to share with a colleague, he gave me this challenge, which he also failed to respond ... I tried, I tried, I used the formulas of quadratic equation, and I've been trying since Friday (here in Brazil is Sunday at 22:33), and could not, and I ask your help, and please believe me, I struggled, tried to make substitutions, tried both, and I'm confused ... I must find the values of $ a, b $ and $ c $?  Consider a parabola whose roots, other are $x'$ and $x''$, and such that $x'=-x''$ where $x'> 0$. Let $$A = (x', 0)$$ $$B = (x'', 0)$$ and $V$ the vertex of the parabola. Suppose that the equation of this parabola is $$y = ax^2 +bx+ c$$. Calculate the value of the discriminant $$\Delta=b^2-4ac$$, so that the triangle is equilateral AVB.


How can I represent a randomForest object in a way that "unlocks the black box" in R?

I have a randomForest object in R, and am trying to extract prescriptive insights, as I would with a tree. This is for a binary classification problem.   Given this setting, my main question is: How can I make sense of what values of what features are associated with each classification? For example, is there a way I can analyze the randomForest object to understand that values of feature1 between 0.5 and 0.8 are likely associated with a classification of "1"?  I would imagine there is something I could do using the votes for each object (given its feature values), or the feature importance for each feature in the forest?


Prove $R$ is commutative if $x^2=x$ for every $x\in R$.

I need to prove that $R$ is commutative, that is for each $x,y\in R$ $xy=yx$. I think for a ring to be commutative, it needs identity such that $1_R\cdot x=x=x\cdot 1_R$, $1_R\not=0_R$.  so,   $xy=1_R(xy)=1_Rx\cdot 1_Ry=1_Ry\cdot 1_Rx=(yx)1_R=yx$ Dose it make sense? ----Ok does not make sense!

Use Triangle Inequalities to Prove an Inequality

Use the triangle inequalities to prove that:  $$\frac{|a+b|}{1+|a+b|}\le\frac{|a|}{1+|a|} + \frac{|b|}{1+|b|}$$ for all $a,b\in\mathbb{R}$.  I've made it this far, but it doesn't seem to be helping much; what I end up with at the end isn't very useful:    Clearly I'm taking a wrong turn somewhere, but I'm not sure what else to try.  Any advice?


How can we put pressure on Stack Exchange Inc. without damaging the community?

Is there a constructive way to put pressure on Stack Exchange (the company) without putting any pressure on the community in general and the moderators in particular?  Goals   Give Monica her diamond(s) back, with a public apology if the accusations were not founded. Address the underlying issues that led to this blowing up:   Significant policy changes without review; Not assuming good intent when people ask questions; Dictating to—rather than working with—moderators and the community; Attacking or going silent when challenged; Insufficiently asking the community they claim to want to protect for their input on how to do so.    Desired properties  The methods to achieve these goals should:   Be constructive. No trolling, no personal attacks, no targeting of minorities. Be sufficiently effective to change some of the company's KPIs to red () Not require any additional work from the moderators. There's an extreme amount of pressure already, but it's been mostly directed towards the community. Be reversible as soon as improvements are noticed. The goal isn't to permanently damage the company but to force the company to realign with the community. Stack Exchange is still doing a lot of things right.   Past actions  Those actions didn't seem to impress corporate very much:    (While it has a huge impact on the community and the content, there hasn't been any sign that the higher ups seem to care at all). .     What else could work?   Offer a platform for SE employees to anonymously share information relevant to the current problems. Some of the employees clearly feel a strong link to the community, but they are apparently forced to either stay silent or repeat corporate buzzwords. Stop using Stack Exchange paid products at work (e.g. ) Advise everyone to enable Ad-Blockers on Stack Exchange. Change our . Reach out to a prominent Twitter user and let them publicly complain about one of the many recent problems.   Any suggestion is welcome.


I'm using a hosted Linux machine so I don't have permissions to write into the /usr/lib directory.  I need Spreadsheet::Read and few other modules to be installed.

How to prove the function $e^x$ is continous for all real numbers

We have been asked to prove the above statement through the two sub-proofs:   Firstly we must prove that $e^x$ is increasing and then prove that $\log(x)$ is also an increasing function.   After we are asked to prove that using the delta-epsilion definition of a limit that $\lim_{x \to 0} e^x = 1$.   I have done all of this but still don't see where the instructor is going with this.


how do i use an equivalent of == with strings c#

hi so i am new to c# and i had a problem while i was trying to solve a little riddle: i need to find how many a-s are in a certain string.     int anum = 0;     string a = Console.ReadLine();     for(int i = 0; i < a.Length; i++)     {         if (a[i] == "a")         {             anum++;         }     }     Console.WriteLine(anum);  while i was solving it there was an error that i couldn't fix: '==' cannot be applied to operands of type 'char' and 'string' i tried googling it but it didnt help please help


Infinite sequence of digits without consecutive repeating subsequenes

Problem description:  Suppose we use a set of digits $\{0,1,2\}$ to form a sequence, for example \begin{equation} 120210120102012102010210120212010\cdots  \end{equation} The length can be finite or infinite.  The sequence is invalid if there are two finite subsequences appears consecutively. For example, the following sequences are invalid  \begin{equation} 0{\bf 11}\cdots, \quad 010{\bf 201\, 201 }\cdots  \end{equation} where the consecutive subsequences are highlighted.   Question: Does there exist a valid sequence of infinite length? (a non-constructive proof is also acceptable; but a constructive one would be better.)  One way to think about it:  We can transform the sequence to a (base 3) real number,  \begin{equation} 120\cdots \rightarrow 0.120\cdots  \end{equation} Then the only possible infinite sequence should be a irrational number. Irrational number has no period, which means the pattern will not repeat infinite many times, but may repeat finite many times. A famous example is the ,      The Feynman point is a sequence of six 9s that begins at the 762nd   decimal place of the decimal representation of $\pi$.   So not all irrational number($\le 1$) are valid sequences.   I use a short program to do enumeration, but it quickly falls in exponential growth of candidates. I failed to come up with a contraction.   Generalization:  Can we take a larger set like $\{0,1,2,3, \cdots, n\}$? Can we relax the constraint to be three consecutive repetition or more?  Motivation  This problem origins from  in chess,     In chess and some other abstract strategy games, the threefold   repetition rule (also known as repetition of position) states that a   player can claim a draw if the same position occurs three times, or   will occur after their next move, with the same player to move. The   repeated positions do not need to occur in succession. The idea behind   the rule is that if the position occurs three times, no progress is   being made.   It reduces to the proposed problem if we modify the this rule to be "the same position occurs two times with the same sequences of moves".   Thanks for your help.  Edit: I find a related question:


Addition of two elements in a field with four elements

I have just started out learning about fields and had tried practicing solving some questions. However, when I encountered this question, I wasn't really sure how to tackle it.     Let $\mathbb{F} = \{0,1,a,b\}$ be a field with four elements.   Prove that $1 + 1 = 0$.    I wanted to show that $1 + 1 = a$, $ 1 + 1 = 1$, and $1 + 1 = b$ would all result in a contradiction. So, I started with supposing that $1+1= a$.  Since I have already proved that $a \cdot b =1$, $a^2=b$, and $b^2=a$, I thought about using at least one of these pieces of information to arrive at a contradiction, but I can't seem to figure how to use them in this case.  In the question, a hint is also given which suggests showing how assuming that $1+1 =a $ will let us make use of $1+a$ and $1+b$ to arrive at $a^2 =0$, which is impossible. But I can't seem to understand how to use it.  Any help would be appreciated.


I'm drawing maps in Illustrator. Our way of depicting divided highways is parallel lines with a fill. Here is an example:    The way I did this was a 1 point yellow stroke, command c, command f, send to back, explained stroke to 2 points  and make black.  These are a pain to make and edit. I'm wondering if there's a way to do this with a single stroke.


how to prevent grep from printing the filename every time there is a match

As I go through multiples files, I want grep to print the filename of the first match.  For example:  grep -nHC 2 "show reload" wgltva-811sono1-dc*   Right now, I am searching for a string in multiple files, but I get the filename everytime.  wgltva-811sono1-dc0-sw.show.tech.txt-1249-abc wgltva-811sono1-dc0:------------- show reload  wgltva-811sono1-dc0-sw.show.tech.txt-1251-abc -- -- wgltva-811sono1-dc0-sw.show.tech.txt-1333-abc wgltva-811sono1-dc0-sw.show.tech.txt:1334:------------- show reload cause history ------------- wgltva-811sono1-dc0-sw.show.tech.txt-1335-abc -- -- wgltva-811sono1-dc1-sw.show.tech.txt-1249-abc wgltva-811sono1-dc1-sw.show.tech.txt:1250:------------- show reload cause full ------------- wgltva-811sono1-dc1-sw.show.tech.txt-1251-abc -- -- wgltva-811sono1-dc1-sw.show.tech.txt-1331-abc wgltva-811sono1-dc1-sw.show.tech.txt:1332:------------- show reload cause history ------------- wgltva-811sono1-dc1-sw.show.tech.txt-1333-abc   What I would like is the following: Display the filename once and display one line before and one line after the match.  **wgltva-811sono1-dc0-sw.show.tech.txt-1249-** abc ------------- show reload cause full ------------- abc -- -- **wgltva-811sono1-dc0-sw.show.tech.txt-1333-** abc ------------- show reload cause history ------------- abc -- -- **wgltva-811sono1-dc1-sw.show.tech.txt-1249-** abc ------------- show reload cause full ------------- abc -- -- **wgltva-811sono1-dc1-sw.show.tech.txt-1331-** abc ------------- show reload cause history ------------- abc   I would like to know some suggestion on how to do this. I would prefer not to do any linux scripting, as I am a beginner. However, if that is the only solution, I am all for it.


Use network reputation rather than site reputation for reminding users to accept answers

Users with insufficient reputation on an SE site are reminded that they can accept an answer when they upvote an answer to their question. I believe this should be based on "cross-network" reputation (as reputation is displayed in chat) rather than the site reputation. Yes, my reputation on SO is a mere 250, but my 6172 reputation on MSE should suggest that I have a clue how the SE model works.

Unable to present my accepted paper in conference. Can I now submit the paper to another conference?

My one technical paper was recently accepted for one international conference.  But, unfortunately, I am not able to attend as the Conference dates are conflicting with my official assignments. I intimated the Conference about my inability to attend. On my request, the conference acknowledged that they will not publish my paper to their Journals/proceedings. (I have the full set of email communications with the conference secretariat.)  I wish to submit the same paper for an IEEE conference. Is there any issue? Please advise.

Appropriate resolution of images for image classification?

I am attempting to perform image classification on some maps that I have in PNG format.  This classification is failing due to there being too many many pixels in the training samples (I appear to be having the same problem as this user: ).  As you can see in the picture, a relatively small training area contains a huge number of pixels as shown in the count column.  The PNG image that I imported to GIS is ~4000 x ~4000 pixels.  The number of pixels in this sample is larger than the number of pixels in the entire .png image!    Is there a setting I need to change to get ArcGIS to recognize the resolution of the image for the sake of classification?

My Wordpress Dashboard is suddenly quite buggy. To be specific just the admin menu is buggy. When I navigate somewhere in admin area some of the menu items disappear as you can see on the following screen.    After I move mouse over the menu some items re-appear but not correctly positioned as you can see on the next picture (see Updates text).    After I reload the page once or twice (reloading the same page, not navigating somewhere else) or Collapse and Expand menu again menu is fixed.   I don't use any plugins. I have tried to update Wordpress (manually) but it didn't help. I am currently using Wordpress 4.3, Google Chrome  45.0.2454.85 (Official Build) (64-bit), and Ubuntu 15.04.  I have just tested FireFox and there seams to be everything OK so it seams to be something with Chrome, but when I've checked console (in Chrome) there are no errors. The errors might have something to do with Chrome recent update.

How can I tell whether Pokémon were hacked/cheated?

I have been playing Pokemon Diamond a few years ago and I remember that I have some pokemon which were cheated. A while ago I purchased Pokemon Black 2 and Pokemon Y and wanted to get all my old pokemon to the newest edition, in this case Y.  Before doing so I would like to find out which pokemon were legitimately catched or acquired via events and which ones were cheated. Is there any service or way to do so?


Ingredients to Get Started with Indian Cuisine

What are the bare minimum ingredients / spices / etc that I would need, to make some tasty  dishes for a wide array of palettes (in case I can convince friends to try my cooking).

How to prove that a set of continuous functions is not closed in (C([0,1]),d1) using a graph (find a function fn such that fn→f but f ∉ set).

I understand how to prove that for the set M = {f ∈  C([0,1]) : f(1) = 0} is closed in (C([0,1]),d(infinity)) using sequence of characterization but not sure how to prove it is not closed with respect to the d1 metric. There was a hint to draw a function fn and a function f (which is just f=1) and I am not sure how to a) know that this set F is not closed in the first place (so I know that I have to prove it is not closed) and b) how do I know what kind of graph to draw.

What can I do to minimize my chances of getting banned?

One thing that I have been doing that may hurt me is that when an answer gets down votes I delete the answer and rewrite it.   I don't just rewrite it because I have found that the down votes prejudice subsequent reviewers against my answer. I usually end up with a good answer that gets upvotes or at least remains at zero.   Although the official position is to rewrite the question or answer I have found that almost never works. This seems to me that my idea of bias against down voted questions is justified. How can this best be resolved?


I'd like to return a value from a python subprocess call corresponding to the kind of error returned. E.g.:  test.py  RETCODE_OK = 0 RETCODE_THING_1_FAILED = 1 RETCODE_THING_2_FAILED = 2  def main():     return RETCODE_THING_2_FAILED  if __name__ == '__main__':     main()   Then I'm calling it with subprocess, like so:  >>> import subprocess >>> proc = subprocess.Popen('python test.py', shell=True) >>> proc.communicate() (None, None) >>> proc.returncode 0   I'd like this to return whatever was returned in main(), in this case 2. I've also got other stuff in the stdout and stderr streams, so I can't just print RETCODE_THING_2_FAILED and get the stdout.


I am trying to use the hieroglyph package (variously known as hiero or HieroTeX) for typesetting Ancient Egyptian hieroglyphs. Having read related questions    I followed the following steps:  Download the ZIP archive from . Unzip and use WinZip to unzip the two TGZ files and their contents. Copy the two texmf folders into a single folder, which I called texmf-hiero. Using the MikTeX Console, added the textmf-hiero folder to the list of root directories. Using the MikTeX Console, ran 'Refresh file name database' and 'Refresh font map files'.

I have a GML layer representing an hexagonal grid that I would like to include in some maps. In QGIS (version 2.14.2) I applied a graduated style and completely removed the polygon border:    However, in the map canvas the borders are still being portrayed:    Zooming in one can see the border around each polygon, it is thin, but it is still there:    Suspecting this was an issue with the map canvas itself, I tried to produce some maps with the Print Composer. Even in vector format the polygon borders are portrayed. Please check these files:       Is there any way to force QGIS to remove these borders?


Let $A,B\in\text{Mat}_n(\mathbb{C})$ if $A$, $B$ commute, then $\det(A^2+B^2)\geq 0$

Let $A,B\in\text{Mat}_n(\mathbb{C})$. If $A$, $B$ commute, then $\det\left(A^2+B^2\right)\geq 0$.   We know: $A^2+B^2=(A+iB)(A-iB)$ so $$\det\left(A^2+B^2\right)=\det(A+iB)\det(A-iB)=\det(A+iB)\,\overline{\det(A+iB)}$$  I'm stuck here, can someone help me?   Is it correct to say $\det(A+iB)\,\overline{\det(A+iB)}=\bigl(\det(A+iB)\bigr)^2$?


Will deadlocks occur when deleting rows from a table that is being added to by another process?

I have to archive data from a table into another table whilst the original table is in use. The archival process is to copy the rows into another table and then delete the rows from the original table. The rows to be archived are selected by a column that has the Identity property.  A factor is that the table from which the rows are being archived will be in use - new rows will be written into the table as the archival process is running. This is a 24/7 application that cannot be stopped.  The rows that are being deleted are at the low end of the Identity column numbering whilst the new rows will be being added at the end of the table.  My concern is deadlocks. Is there a chance that deadlocks could occur between the 2 processes?  The archival process will be run from a Stored Procedure? Should I set the DEADLOCK_PRIORITY to LOW to ensure that if a deadlock does occur that the archival process will be killed and not the running application?  Should I also set TRANSACTION ISOLATION LEVEL?

Why are some journals prestigious and others aren't?

What makes the journal "prestigious" in the first place? I can't myself find any sensible answer.   One candidate reason is that some journals have better reviewers. But reviewers are usually not paid, so if it were true that the good reviewers flock to these select few journals, they must be doing so because those journals were prestigious or attractive in some sense in the first place, and so we are back at our original question.   Another possible reason is that some journals only publish papers of a high quality. This seems wrong as well. For example, if I decided to create a journal which only published extreme-super-duper-mega-high quality papers, nobody would care about it. Rather it seems to be the other way around: these journals publish the best papers because they are prestigious and therefore receive the attention of the best academics and their best papers. So again, we are back at the original question.   A third reason could be readership, but, again, the readership is a consequence of the prestige the journal already possesses. We still don't know where it came from.

Split string and keep delimiter in sequence

Is there a clever way to do the following string manipulation in C#?  I have any kind of string and im looking for a specified delimiter. The code should divide the string in words before and after delimiter and also include the delimiter. The delimiter could be several times in a row and also could be in the start or the end.   // PSEUDO CODE string = "Hello****wide****world"; delimiter = "****";  // result should be a list<string> like {"Hello","****","wide","****","world"}


Estimating age of the universe by Hubble's law?

Hubble's law states that $v=Hx$  Age of the universe is calculated by $T= \frac{x}{v} = \frac{1}{H}$  but the velocity is not constant; it changes with distance, so I think that this equation cannot be applied because simply the velocity is NOT uniform  $v$ should have been replaced with $\frac{\mathrm{d}x}{\mathrm{d}t}$, so it gives this differential equation $\frac{\mathrm{d}x}{\mathrm{d}t}=Hx$.  Nevertheless, when this differential equation is solved, and we substitute for initial condition ($x=0$ when $t=0$), it appears that there are no solutions, because it will be an exponential function, which can't take the value $0$ ever.   What is wrong with my understanding?


Suggestions to reduce red skin tones on Sony A7iii

Recently moved from Canon to Sony a7iii. My wife has pointed out that a lot of the skin tones look much more red than previously.  Any suggestions on avoiding this?  I've seen there is a slider to adjust white-balance but would prefer not having to manually guess/set this for every photo.  Does the Sony have skin specific settings or picture styles that might help?


Structure of a C++ Object in Memory Vs a Struct

If I have a class as follows     class Example_Class     {        private:          int x;           int y;         public:           Example_Class()           {               x = 8;              y = 9;          }        ~Example_Class()         { }     };   And a struct as follows  struct {    int x;    int y; } example_struct;   Is the structure in memory of the  example_struct simmilar to that in Example_Class  for example if I do the following  struct example_struct foo_struct; Example_Class foo_class = Example_Class();  memcpy(&foo_struct, &foo_class, sizeof(foo_struct));   will foo_struct.x = 8 and foo_struct.y = 9 (ie: the same values as the x,y values in the foo_class) ?  The reason I ask is I have a C++ library (don't want to change it) that is sharing an object with C code and I want to use a struct to represent the object coming from the C++ library. I'm only interested in the attributes of the object.  I know the ideal situation would be to have Example_class wrap arround a common structure between the C and C++ code but it is not going to be easy to change the C++ library in use.


Let $X$ and $Y$ be independent exponential variables with rates $\alpha$ and $\beta$, respectively. Find the CDF of $X/Y$.  I tried out the problem, and wanted to check to see if my answer of: $\frac{\alpha}{ \beta/t + \alpha}$ is correct, where $t$ is the time, which we need in our final answer since we need a cdf.  Can someone verify if this is correct?


Why are some lens hoods petal shaped and others not?

How can I navigate my scene FPS style similar to how Unity does?

Ask Google search to use only the exact words typed, no spellcheck or synonyms

How can I ask Google search to use only the exact words (not entire phrase) I typed and not to use spell check and similar words/synonyms?  Here is a string I entered into Google's search form:  Mayavi plot3D vary tube radius   Many of the results I got back do not have the word "vary" but have the word "very" instead in bold, indicating Google searched specifically for "very" in addition to "vary."    Google also found results that had "diameter" instead of "radius" in bold, which although seems to be well-meaning, is not actually helpful for me, as "radius" is the name of a Mayavi variable I am working with, not "diameter."  Can I stop Google search from reporting results found with words similar to but different than the words I searched with, and how?

Solve the recurrence relation $f(n) = f(n − 1) + f(n − 2)$ with initial conditions $f(0)=1$, $f(1)=2.$   So I understand that it grows exponentially so $f(n) = r^n$ for some fixed $r$.  This means substituting this $r^n = r^n-1 + r^n-2$ which gives the characteristic equation of $r ^ 2 - r - 1 = 0$. I'm not 100% sure where to move on from here.


Is black a color or absence of color? When there is no light, everything is black, so how can we say that black is a color?


I find SE an amazingly well thought-out platform in so many respects, so I am a bit puzzled that what I am about to describe has not been solved/addressed yet.  I can specify my interests by keeping a list of tags that I want to follow. However, on the "my tags" unanswered tab (or on any other tab for that matter) I can not choose how the questions are ranked. They seem to be roughly ranked by descending number of votes, with occasionally some fresh stuff thrown in at the top.  As a result, much of this list feels quite stale, since it is made up of questions that have been collecting votes (and dust) for a while.  Hence my request: I would like to be able to click "I'm bored with this question, please don't show it to me for a while." so that my list actually fills up with things I haven't looked at or am not bored with yet, and I don't have to wade through screenfuls of oldtimers to detect a newcomer.  One variation could be "I'm bored with this question, please hide it until someone comes up with an answer of at least 3 upvotes".


Confusion about usage of "who" in a relative clause

I'm confused about two particular examples where "who" is used as a relative pronoun:  Example-1: ...people who I have no idea who are. ...people who I have no idea who they are.  Example-2: ...people who we have no idea what their intentions are.   What is the correct phrasing for these two examples? Also, is it okay to drop "who"? I've seen instances of example-1 on various webpages; in fact, a quick google search for "who I have no idea who they are" gave 97,200 hits. So, is it acceptable in colloquial usage regardless of whether it is grammatically correct or not?   Thanks.

I am trying to show that that the the cantor set is homeomorphic to cantor space and here is the function defined from $C$ cantor set to $\mathcal{C}$ Cantor space, let $a_{n}$ be $0$ or $2$ And for all $x\in C$, $x=\sum_{i=1}^{\infty}\frac{a_{n}}{3^{n}}$, the function $f(x)=(\frac{a_{1}}{2},\frac{a_{2}}{2},...)$ it is easy to check that $f$ is bijective, but How can I show that $f$ is continuous ? If I can show that’s $f$ is continuos, $f^{-1}$ is easily continuos because the function is Fromm compact space to Hausdorff space. Any help about the continuity will be greatly appreciated


Python get unique element in array but maintain its original sequence

I would like to get the unique element from an array with specific sequences. For example, initially, I have array as following: array([3, 3, 6, 6, 5, 5, 5, 5, 2, 8, 8])  I would like to get the unique element from the array above and maintain its original order sequence. The sample output as following: array([3, 6, 5, 2, 8])  I know that using numpy.unique() will get the unique elements for the array, but it will return sorted unique elements. However, in my case, I need the output in the original sequence. To generate toy example, here easy for you to just copy & paste arr = np.array([3,3,6,6,5,5,5,5,2,8,8])  At the time I post this, I still working on this, and I wish to get your suggestion so that I could move to the next part of work. Your advice will be highly appreciated. Thank you for your time!


What is happening when I assign a list with self references to a list copy with the slice syntax `mylist[:] = [mylist, mylist, ...]`?

I was just looking at the implementation of , when I stumbled across this snippet:  root = []  # root of the circular doubly linked list root[:] = [root, root, None, None]  # initialize by pointing to self   I am familiar with circular and doubly linked lists. I am also aware that new_list = my_list[:] creates a copy of my_list. When looking for slice assignments or other implementations of circular doubly linked lists, I could not find any further information on this specific syntax.  Questions:   What is going on in this situation. Is there a different syntax to achieve the same result? Is there a different common use case for some_list[:] = some_iterable (without the self reference)?


What are good questions to ask when interviewing intranet users for persona development?

I'm part of an external team hired to improve a software engineering company's intranet.  I have been tasked with developing a usable set of personas out of a pool of around 300 employees. The personas, along with heuristic evaluation and usability testing, will be one of the tools used to develop a design-decision making framework.  In order for the personas to be an effective tool I know I need to ask the right questions, the right way. Does anyone have some experience interviewing intranet users that they can share?

I currently have a file on the root of my external hard drive simply named ._., which I am guessing was added to my hard drive after using it on my MacBook a while ago.  I'm trying to delete this file on my Windows 10 machine; however Windows keeps claiming the file cannot be found.

Why is double stranded DNA considered to be one molecule?

Wikipedia, for example, refers to DNA as "a" molecule, not two separate molecules forming a double-helix structure. Isn't this technically incorrect? There are two separate polynucleotide strands (each that can be considered one molecule on its own as the monomers are joined together by covalent bonds), and the strands joined together by hydrogen bonds and not covalent/ionic bonds along their length. Doesn't that exempt them from being considered one molecule, as the bonds joining them are intermolecular and not covalent or ionic?


Figures on left pages, text on right ones with class book, numbering only on right pages

My problem is that I would like to have either blank or figures on the left pages, and text on the right ones, with the numbering of the right pages to be 1,2,3,4,5 and not 1,3,5,7.   It means, in a book-derived class, to have right pages, with the odd layout, but with also an even number half the time.   It also means that I would like to have, by default, a blank page everywhere on a left page, except if a picture has been defined somehow before on the previous page.     Update:  I've tried it. There is a little \makeatother missing, but I spotted it right away. It seems to work fine alternating pages and inserting blank or figure pages. However, I have two problems:   The class (book-derived) sometimes introduces blank pages of its own. I can tweak it, but would prefer to be able to turn on/ turn off the action of the blankpage routine along the course of the document.  The layout of the text pages depends on the odd/even number of the page. Since my text pages have odd and even numbers (which is the intended result), the layout is now alternatively odd or even, which is not what I would like, since there they will all be on the right hand side of the doc when open...   Do you have any clue as to how to manage this? I think the second problem is way more difficult...  Thank you already for this answer both simple and effective for achieving the result.   EDIT 2 (19/12/2011) : The answer from Bruno Le Floch seems to me more complete and I recommend it.


Does length of a hosepipe affect pressure/flow

I have connected a hosepipe to my shower drainage plumbing (1st floor), which I am running into the garden (ground floor) as a kind of grey-water system. However, the water drains out the shower terribly slowly.   The hosepipe is 50 meters long. I'm wondering whether the length is the problem. It probably only needs to be 20m to reach the end of the lawn. I don't want to cut it and ruin the hosepipe without knowing with some certainty that a shorter pipe will increase the flow/draining rate.   Any opinions?

I am confused whether voltage across inductor is $$ \ V = - L* di/dt\, $$ or $$ \ V = L* di/dt\, $$ Does it have to do with inductor being in AC or DC?   EDIT: okay based on answers I found, confused me that if there is a negative sign in the formula, it is back emf that is been generated by the current flowing through a coil and according to Lenz's law some force have to oppose that change! Now if $$ \ V = - V_{emf}\,$$ than how do I calculate actual back emf generated by an inductor?


How to use masks on video so that some elements appear in the foreground and others in the back in VSE

I have two people in my video - one in the foreground and the other in the background. I want to place an image of a cage over the person in the background of the video, but the issue I have is the person in the foreground would then be covered with the image also. How do I place this image behind the person in the foreground to make the scene realistic? (I'm using the video editor workspace).


Why does multicollinearity increase the variance of the coefficient estimates?

that severe multicollinearity is a problem because it can increase the variance of the coefficient estimates and make the estimates very sensitive to minor changes in the model. The result is that the coefficient estimates are unstable and difficult to interpret. What are the mathematical reasons for that phenomenon?


css before and after line's vertical aligning

I am trying to vertical-align 2 lines and a title. But it doesn't work correctly. My html code is-

Our Services

  and style.css: .our-service-title{     color: #222222;     font-size: 24px;     font-weight: 600; }  .our-service-title:before, .our-service-title:after{     content:" ";     display: inline-block;     vertical-align: super;     margin-left: 10px;     margin-right: 10px;     width: 30px;     height: 3px;     background-color: #FFC000; }  it shows like the following output:  How can I align this correctly?

Prove that if f is continuous in A then |f| is also continuous.

Prove that if $f$ is continuous in a then  $|f|$ is also continuous. I have this exercise for homework of calculus I, and I was thinking that it could be treated by cases when $f>0$ and $f<0$, but when I make $f<0$ then it results $-f(a)$, following the continuous definition: $lim_{x\to a} f(x)=f(a)\dots$


To prove that $(a^n-b^n) \nmid (a^n+b^n)$

Prove that there are no positive integers $a,b,n>1$ such that $(a^n-b^n)\mid(a^n+b^n)$  My approach:  Let $$\frac {(a^n+b^n)}{(a^n-b^n)}=k$$ where, $k$ is a positive integer  $$\therefore k=1+\frac {2b^n}{a^n-b^n}$$  Now, I am unable to prove that $\frac {2b^n}{a^n-b^n}$ is not an integer.  Please help me with my solution or provide a completely new solution.


App keeps crashing & rendering error since update to 1.0.68

I can reproduce that every time now, I go to a site, open an article, then to the next site, open another article. The Feed page pops up for a second, the article page lays over this with some some transparent areas (see picture). The same app-version is ok on a Smartphone with Android 4.4.2. I also sent in some bug reports.    Edit  1.0.71 isn't the solution yet. I go to Meta SE, then to an article. When I want back to Meta SE again, it crashes. Much earlier than before. I already sent in a bug report for this.  Another Edit  I can describe it better now. From the questions-page of a site I go to a post. When I use the back button, everything is ok, I can go to the next site. When I try to go to the next site directly from the post, it crashes. This only happens on the Nexus 10 with Android 5.1.1, App version 1.0.71. Hope this helps.  Edit3  This is fixed in 1.0.73 now. Thanks again.


I'm writing an article using the revtex4 document class, but it appears to be incompatible with subfig (which also seems to be loading caption). How can I title some subfigures in my revtex4 document?  The following minimal example shows how just loading subfig breaks the formatting of figures as defined by the document class.  \documentclass[twocolumn]{revtex4} % Uncomment the following line to see the problem %\usepackage{subfig}  \begin{document} \begin{figure} \centering   \framebox[5cm]{\raisebox{3cm}{}} \caption{Some dummy title for my figure which should be long enough           to occupy at least a couple of lines, and maybe even a bit          more. That's good.} \end{figure} \end{document}   Furthermore, the caption package complains with the following warning  Package caption Warning: \caption will not be redefined since it's already (caption)                redefined by a document class or package which is (caption)                unknown to the caption package. See the caption package documentation for explanation.   So the question is, how could I solve this problem? Is there an alternative to subfig which I could use together with revtex4?


Javascript - Script1 stops until script2 is running

I have two script.  First:  a = 0; for (var i = 1000000000 - 1; i >= 0; i--) {     a += i; }; console.log(a);   Secend:  setInterval(function(){     if (l.data('pos') == 0) {         l.css('margin-left', '10px');         l.data('pos', '1');     }else{         l.css('margin-left', '0');         l.data('pos', '0');     } }, 100);     As you see, browser run second section after finishing first section.  Can I run first section in background and second section runs from document ready?


For some reason, I can't zoom in more. I'm on mac so i press cmd scroll but i can't zoom in. I can zoom out slowly but not in. Also, when i move my view (not sure if it is the right term), it goes way too fast, a slight scroll and it moves a lot. Also, when i use the hand to move, it goes EXTREMELy slowly Edit i think it's because i only zoom, so there's a point where it can zoom in anymore. Edit 2: I fixed it by toggling lock to object


Assign p-values to all data point in the population in order to demonstrate some of them are not normal

a very naive question for some of you. I have a population of 80000 data points. Some points in the population are many SD away from the rest of the population and they could be easily identified and visualized assigning them a p-value. I know that excluding those values, the population follow a nice normal distribution. What I ask you today is whether you can suggest me an approach to assigning a pvalue to each data point in the population where the null hypothesis is that the data contribute to the normality.


Can someone give me a recommendation on homological algebra textbooks? I would like something that are accessible to a beginner (i.e., someone who have studied abstract algebra) and that have  1) an account on preadditive, additive, monoidal, abelian, triangulated categories, respectively,  2) motivations from algebraic topology exploited, (an elementary example that comes into my mind is the mapping cylinder/cone construction explained in contrast with Puppe sequence,)   3) an explanation on module theoretic topics like injective / projective resolutions,  4) a coverage of sheaf theory, cohomology of groups, and Galois cohomology.


How to show that $e^x$ is differentiable?

I tried to search for a few minutes but I didn't find this question so I hope it's not a duplicate.  So I want to show that $(e^x)' = e^x$. To do that, I must proof that the limit: $$\lim_{h\to0}\frac{f(x+h) - f(x)}{h} = \lim_{h\to0}\frac{e^{x+h} - e^x}{h}$$ exists and equals to $e^x$.    So I have: $$\frac{e^{x+h} - e^x}{h} = \frac{e^x \cdot e^h - e^x}{h} = e^x \bigg(\frac{e^h - 1}{h}\bigg) \\ e^h - 1 = z \implies e^h = 1+z >0 \implies h = \ln(1+z)$$ Because of the continuity of the $\ln$ and $e^x$ functions, we have: $$h\to 0 \iff e^h \to 1 \implies z\to0 \\ z > 0 \implies \frac{1}{z} \to +\infty \\ z < 0 \implies \frac{1}{z} \to -\infty \\ \frac{e^h - 1}{h} = \frac{z}{\ln(1+z)} = \frac{1}{\frac{1}{z}\ln(1+z)} = \bigg[ y = \frac{1}{z} \bigg] =  \frac{1}{y\ln(1+\frac{1}{y})} = \frac{1}{\ln(1+\frac{1}{y})^y} \\ h \to 0 \implies |y| \to +\infty \implies \bigg(1+\frac{1}{y}\bigg)^y \to e \implies \\ \lim_{h\to0}\frac{e^h - 1}{h} = \frac{1}{\ln e} = 1 \implies (e^x)' = e^x \cdot 1 = e^x$$    But how do I prove that $\lim_{\pm\infty}(1 + \frac{1}{x})^x = e$ ?    We defined $e$ like this: $$\lim_{n\to\infty} \bigg(1 + \frac{1}{n}\bigg)^n = e \space \,, \space n\in\mathbb{N}$$   I thought of the sandwich theorem:  $\forall x \geq 1 \,, x\in\mathbb{R} \,, \lfloor x \rfloor \leq x < \lfloor x \rfloor + 1$ and $\lfloor x \rfloor , \lfloor x \rfloor + 1 \in \mathbb{N} $ and if I denote $\mathbb{N} \ni n = \lfloor x \rfloor$ I have: $$ \bigg(1 + \frac{1}{n+1}\bigg)^n \leq  \bigg(1 + \frac{1}{x}\bigg)^x \leq \bigg(1 + \frac{1}{n}\bigg)^{n+1} \\   \lim_{n\to+\infty}\bigg(1 + \frac{1}{n+1}\bigg)^n = \frac{\lim_{n\to+\infty}\bigg(1 + \frac{1}{n+1}\bigg)^{n+1}}{\lim_{n\to+\infty}\bigg(1 + \frac{1}{n+1}\bigg)} = \frac{e}{1+0} = e \\  \lim_{n\to+\infty}\bigg(1 + \frac{1}{n}\bigg)^{n+1} =  \lim_{n\to+\infty}\bigg(1 + \frac{1}{n}\bigg)^n \cdot \lim_{n\to+\infty}\bigg(1 + \frac{1}{n}\bigg) = e \cdot (1 + 0) = e$$  and now I could apply the theorem but then again, how do I show that this: $\bigg(1 + \frac{1}{n+1}\bigg)^n \leq  \bigg(1 + \frac{1}{x}\bigg)^x \leq \bigg(1 + \frac{1}{n}\bigg)^{n+1}$ is true? I mean, I can say that (left side): $$ n+1 > x \implies \frac{1}{n+1} < \frac{1}{x} \implies 1 + \frac{1}{n+1} < 1 + \frac{1}{x} \\ \forall y\in\mathbb{R_+} \space n \leq x \implies y^n \leq y^x \\ \implies \bigg(1 + \frac{1}{n+1}\bigg)^n \leq  \bigg(1 + \frac{1}{x}\bigg)^x$$ and by analogy the right side but is this a proof in terms of limits?  and that's just $+\infty$ for $x \geq 1$, what do I do for $-\infty$ ?   For $x\in\langle 0, 1\rangle$, a substitution $y = \frac{1}{x}$ gives me: $$\lim_{y\to 0}\bigg(1 + y\bigg)^\frac{1}{y}$$  I'll stop here to see if I'm on the right track, any hints, suggestions, edits, comments and answers are welcome!


How do you get a simple logo to look crisp after compression for Twitter/Facebook profile pictures?

Being a complete novice at this but having tried many methods, I cannot get my logo to look crisp in my Twitter or Facebook profile pictures. It looks fine in Instagram. I have been dabbling in GIMP and Inkscape to generate a simple  logo for my social media accounts. In my ignorance I first made a raster logo by tracing a picture in GIMP (pictured).  This worked out fine for Instagram (maybe because the size of the canvas, 1080 px sqaure, was the same as Instagram preferences?). After resizing the image as per Twitter/Facebook recommendations and trying both PNG and JPG uploads, it looks terrible in both at thumbnail size, particularly in the phone versions. I've tried a bunch of different things to solve this (thanks to this fab forum and a few youtube tutorials): changing pixel density, changing export quality, changing file type, using filters, e.g. Gaussian blur, making it transparent, making it white background, etc... I redrew it (roughly) as a vector in Inkscape using the bezier pen tool (pictured below). This was an experiment to see if having a vector version would solve the problem. It didn't, it still looks awful after uploading it at the recommended pixel dimensions, trying both PNG and JPG. It looks extremely pixelated as the thumbnail on a phone.  I'd be happy to start again but I don't know where to start. What do I need to do to create a black and white logo which compresses well in Twitter and Facebook profile pictures?


I'm wondering if anyone can shed light on a worry of mine that a query_plan_hash collision could cause a query to be executed as an entirely different query.  The hash is a 16 digit Hex that sp_help sys.dm_exec_query_stats says is a binary. Therefore it's only a 64 bit hash, and a collision seems very probable (considering SHA1 [160 bit] was just verified to have had collisions).  Would the plan_hash and the query_plan_hash both have to collide for this (query to be executed as an entirely different query) to happen?  I'm also curious if there is a setting somewhere in SQL Server that will allow us to change this hash to SHA2-512 (to reduce the possibility of a collision). Our data is very important.  I searched high and low via Google and Stack Exchange forums.


Getting LaTeX (via pandoc) Working with Hebrew Characters

Casual LaTeX user here, so if something seems dumb/obvious, it probably is.   I'm want to use LaTeX (via pandoc) to create PDFs that contain hebrew characters.   I found  where someone appears to have solved a similar problem.  However, when I create a utf-8 text file (working.tex) with the same content  \documentclass{article} \usepackage{fontspec} \usepackage{polyglossia} \setmainlanguage{hebrew} \setmainfont{Times New Roman} \newfontfamily{\hebrewfont}{New Peninim MT} \begin{document} \title{שלום עולם} \author{שלום עולם} \maketitle  העיר מקודשת ליהדות, לנצרות ולאסלאם, והיוותה מרכז חיי העם היהודי בימי קדם ומושא געגועיו בזמן שהייתו בגלות. משום מרכזיותה בעולמם של המאמינים, הייתה העיר מוקד למלחמות וסכסוכים הנמשכים עד עצם היום הזה. מאז סוף המאה ה-19 התפתחו סביב העיר העתיקה שכונות העיר החדשה, המהוות כיום את רובה המוחלט של העיר. במרכזה של ירושלים השלמה עומד הר הבית, שמפריד בין מערב ירושלים למזרח ירושלים.  בשנת 1981 הוכרזה העיר העתיקה של ירושלים כאתר מורשת עולמית על ידי ארגון אונסק"ו של האומות המאוחדות, והיא נמצאת ברשימת האתרים בסיכון.   \end{document}   and then use pandoc to convert that to a PDF  pandoc --latex-engine=xelatex working.tex -o working.pdf    and then open the PDF     I get zero hebrew characters.    Is there anything wrong with the above document?  Are there common troubleshooting tips for getting hebrew working with LaTeX and pandoc?

How to install a language which is not shown under "installed languages"?

There are any website to review my non native english?

as you can guess I'm a non-native english. When I write an scientific paper, my major trouble is the language and I'm worried about the review of my english. There are any website or community, where I can post my full paper or part of it, and receive a peer review for my english? Thanks a lot.


I was on the Suggested Edit's review tab today, and noticed that this user (take a look at today's ), was putting in hundreds of edits adding the C# tag to questions that didn't really need it. He got over 275 reputation today.   To me, this looked like spamming the edit system to get reputation. I started rejecting them as too minor, with also a custom message telling him this.   Here's one example:  Another:  Another:    And about 20-30 more. I hit my review cap for the day.  Is this valid editing behavior, and, if not, would a mod please get involved?  UPDATE: I've seen a couple of other meta questions about this in the last day, but it looks like the spike in gaming the system is passed.


How can I find the value of the series $$\sum_{n=1}^\infty \frac{1}{(b+n)(a+n)}$$ where $a,b\in[0,1)$?  It is obvious by standard arguments that the series converges, but how can I derive the explicit value dependent on $a$ and $b$.  Thanks  EDIT: $a,b$ can be assumed to be different.


Wire capacity - Total power or just current?

So I've gotten myself into a healthy, educational Facebook discussion.  if you're a member of that group.  When I thought about it, everyone defines wire capacity by current only. The voltage only comes in when talking about wire insulation.  However, I've always thought about a wire's capacity by total power transmitted, not just the current.  Assuming arcs and corona discharges aren't a problem, could I transmit say 10 kW via a #40 AWG wire at 10mA, 1MV DC? The ampacity isn't , but that doesn't look right for wire that's around the width of a hair.  I'm aware of the math behind it (5th year Electronics engineering student) and I can judge what voltage/current I need for X watts versus safety/other constraints, but wires being rated by current only hasn't bothered me up until this point.


ToC formatting - numbers too close to section headers

I am putting together a report as part of a group project for part of physics degree, and I have been having fun trying to format the table of contents correctly. Here is a MWE:      \documentclass[twoside]{article}     \usepackage[a4paper,pdftex,left=1.7cm,right=1.7cm,top=2cm,bottom=2.5cm]{geometry}        \usepackage{blindtext}     \usepackage[english]{babel}     \renewcommand*\thesection{\arabic{section}.0}     \renewcommand*\thesubsection{\arabic{section}.\arabic{subsection}}      \begin{document}     \tableofcontents     \addtocontents{toc}{~\hfill\textbf{Page}\par}     \newpage      \begin{abstract}     \blindtext     \end{abstract}      \section{A section}     \blindtext     \section{Another section}     \blindtext         \subsection{A subsection}         \blindtext         \subsection{Yet another subsection}         \blindtext             \subsubsection{Oh, exciting, a sub sub section!}             \blindtext     \section{Another boring old section}     \blindtext      \end{document}   Which gives something like this as the output:    Not bad, except for the spacing between the sections and their respective numbers is far too small. I tried to fix it by including this in the preamble:      \makeatletter     \renewcommand{\l@section}{\@dottedtocline{1}{1.5em}{3em}}     \renewcommand{\l@subsection}{\@dottedtocline{2}{3.0em}{3.5em}}     \renewcommand{\l@subsubsection}{\@dottedtocline{3}{4.5em}{4.2em}}     \makeatother   giving this:    Although it allows me to adjust the spacing to my liking (not adjusted correctly in the picture, just an example), I seem to have lost the bold font and gained some dots for my sections which were previously absent. I have also lost the nice spacing between sections. I tried getting the bold font back with      \renewcommand\cftsecfont{\bfseries}   but it didn't seem to have any effect. Any advice on how to better format my ToC would be appreciated. I don't have to comply with any specific layout of formatting specified by the university, but I do want it to look clear and professional. The first example was perfect except for the section numbers being stuck right next to the sections, although it was fine for the subsections.


Comment box only half a line tall on mobile

When viewing on mobile, the comment line is only half a line tall, making it really hard to read what I'm typing and fix whatever autocorrect is butchering. Can we make it taller?  It was tested in Chrome and Firefox on my Galaxy S8. It renders correctly when I tell the browser to "Request Desktop", but I think it should also work in mobile view:
