LaTeX code sniffer and/or beautifier? I'm looking for a LaTeX code sniffer and/or code beautifier, because I'm creating a CI server for my LaTeX books and I wanted a few things. :D Biasing circuit - Voltage follower circuit GSC: How to move a site from a domain to sub domain, sub folder or new domain with a sub folder? Is it possible to tell Google's Webmaster Tools that our site hosted on www. has moved to a sub folder, sub domain or a new domain with sub folder? In Ubuntu 13.04 there was an option to use the PPA by Relan in order to get ExFat functionality. Seeing that in Ubuntu this functionality is now available from the repositories without the PPA I tried this but failed to make it work.  So my question is how do I enable exfat support? android how an EditText work as AutoComplete Sometimes I want to learn about a new programming related issue—topics such as DB ORM, search indexer, identity providers, logging, etc.  When I don't know anything about a subject, I ask for benchmarks or comparisons. I got some serious answers like links to tests, pros/cons, and Gartner's reviews. I found these very constructive and helpful. But then the question was blocked or deleted. Sometimes this happens even before I get an answer.  So where would it be more appropriate to ask questions about third party products and/or open source frameworks with which I am completely unfamiliar? I want to burn a Windows ISO to a USB device in Ubuntu. How do I do this?   I know how to burn a Ubuntu ISO into a USB device, but with a Windows ISO it's not the same. Find files in directory with paired names I'm running tests of a variable-size-and-contents test set. Data files are added and removed frequently. I'm looking for an automated way of gathering a file list.  All files are in subdirectories of D; I need the full directory and name added to a text file. However, I only need those files that have a "paired" file, which has the same filename but a different extension (so... different filename, but in a structured way). So, if there is a MyFileName.A and MyFileName.B, then I want D/.../MyFileName added to the file list.  There are .A files without .B files, but no .B files without .A files. If a .A has a .B file, then both files are in the same directory.   Any advice?

How to adjust the spacing for the voltage label? Actually, can  potentially solve the problem? Note that what I am trying to draw is based off of this: Benefits and Drawbacks of Swapping Associations of Positivity and Negativity of the Proton and Electron For historical reasons, I understand that a proton's charge was assigned the label of "positive", the electron's charge was assigned the label of negative, and, crucially, equations of current in E &amp; M are written with the notion that current is the flow of positive charge despite the rarity of actual flows of protons in real systems (which I understand are mostly biological systems).   If the possibility existed to instantaneously and at no cost, retcon these associations such that protons have a negative charge, electrons have a positive charge, and current remains the flow of positive charge, would there be any beneficial or detrimental outcomes?  For instance, would there be:   new interpretations of physical laws that would provide different or better insights into any relevant subfield of Physics significant simplifications to notation in any field of Physics or Engineering significant increases in understanding in the fields of electricity, electronics, electrical engineering, radiation/radiative transport, etc. a noticeably easier learning curve for any subfield of physics dealing with the concept of charge   Additionally, is there a permutation of positive charge, negative charge, and flow of current definition that would improve upon the one I suggested? I'm examining a part of my dataset containing 46840 double values ranging from 1 to 1690 grouped in two groups. In order to analyze the differences between these groups I started by examining the distribution of the values in order to pick the right test.  Following a guide on testing for normality, I did a qqplot, histogram &amp; boxplot.       This doesn't seem to be a normal distribution. Since the guide states somewhat correctly that a purely graphical examination isn't sufficient I also want to test the distribution for normality.   Considering the size of the dataset and the limitation of the shapiro-wilks test in R , how should the given distribution be tested for normality and considering the size of the dataset, is this even reliable? ()  Edit:  The limitation of the Shapiro-Wilk test I'm referring to is that the dataset to be tested is limited to 5000 points.  To cite  concerning this topic:     An additional issue with the Shapiro-Wilk's test is that when you feed   it more data, the chances of the null hypothesis being rejected   becomes larger. So what happens is that for large amounts of data even   very small deviations from normality can be detected, leading to   rejection of the null hypothesis event hough for practical purposes   the data is more than normal enough.      [...] Luckily shapiro.test protects the user from the above described   effect by limiting the data size to 5000.   As to why I am testing for normal distribution in the first place:  Some hypothesis tests assume normal distribution of the data. I want to know whether or not I can use these tests. Why would a spinning space station create a centrifugal force on an astronaut rather than simply spinning around him/her? We often see films with spinning space station that create  by having the astronauts pulled outwards by centrifugal force.  I'd like to know if this would really happen, and if so, why is the following scenario not true:   Take an astronaut in open space. He doesn't move. Put a big open spinning cylinder around him - surely he still doesn't move. Close the cylinder. I still see no reason for him to be pulled outwards. Base-b Representation of an Integer: Why can I make the assumption about number of terms in expansions in uniqueness part?   Reading the book of Koshy I have come across the below theorem. It states that I can write any integer $N$ in a base $b\ge2$ representation $N=a_kb^k+...+a_1b+a_0$ such that $0\le a_i&lt;b$, $a_k \neq 0$ for some $k\ge0$.  In the uniqueness part, why can I assume the expansions contains the same number of terms ? I must prove that all expansions of $N$ equal the one in the theorem, but if I add terms to the expansion by zero coefficients, well, then the expansion is not in the proper form anymore ? (the greatest term in the expansion is $0$ if I add zero coefficients) .  Can someone help clear this out ?     Why can I assume the expansions contain the same number of terms ? If I add terms to the expansion, well then I've violated the form of the expansion ? Which colors make you hungry I am working on a new brand, which is all about food.   What colors should we use for the logo and website?   I keep reading that red makes you hungry, but i would like to stay away from that color. All of our competitors must have read the same articles.
