I'm absolutely new to Linux. I would like to know how to install Ubuntu alongside the pre-installed Windows 8+ OS.  Should I do it with Wubi, or through the Live USB/DVD?  What steps do I need to take to correctly install Ubuntu?

How to make a button appear as if it is pressed? I'm writing a shell script for Linux, using Bash, to translate any video-file into a MP4. For that, I'm using avconv with libvorbis for audio.   Inside my script, I have a question for the user :   read -p "- Audio Quality [scale from -2 to 10] ? "     if [ -n "$REPLY" ] ; then     ABITRATE="-aq $REPLY"     fi   My "ABITRATE" string goes into the final avconv command-line.  But I would like to give the user the opportunity to answer that question with a value in Kb (Kilobit), and translate it into the scale that libvorbis uses. The "scale from -2 to 10" is this :   Quality Kbit/s  Normalization -----------------------------  -2      ~32        y  -1      ~48        y   0      ~64        y   1      ~80        y   2      ~96        y   3     ~112        y   4     ~128        n   5     ~160        n   6     ~192        n   7     ~224        n   8     ~256        n   9     ~320        n  10     ~500        n   I would like to know how to check if my $REPLY is in a range of number.

How do I know I have the correct exposure when shooting in manual mode? I have a Canon XTI which I've been using for a few years now. Most of the time I'm been shooting in one of the "semi-manual" modes like aperture priority or shutter priority, but now I'd like to try using full manual mode. I should have a new EF-S 17-55 f/2.8 delivered when I get home today. Before I was using a variable aperture Sigma 17-70 which made manual mode more difficult with the aperture changing arbitrarily.  I understand the effect of changing aperture and shutter speed, but right now I'm accustomed  to only controlling one at a time. The camera is usually setting the other to get the right exposure automatically for me. So if I'm controlling both how do I know I have the correct exposure? I understand I need to use the metering in my camera but I'm not sure exactly how do do that.   First when should I be using each of the metering modes (Evaluative, Partial, Center weighted, or Spot)? These just change the area of the scene which is metered correct?  How do I know what the meter should read off a specific object? Obviously if I just happen to be shooting a 18% gray wall then it should be at zero, but that can't apply to everything? If I'm shooting a black cat and take a spot meter reading off of the cat then the meter should read less then zero right? But how do I know how much less then zero? Are there rules of thumb I can follow? I've ordered a couple gray cards with my new lens. So experimenting with those should help.  How often should I be changing these settings? Say I'm at a party indoors which is consistently lit. I should be able to set the aperture, shutter speed, and ISO and just forget about it unless the lighting changes correct? Does the same apply to outdoor scenes? I've been hesitant to use manual mode in the past because I felt like I was spending a lot of times messing with settings before each shot. But not I'm realizing that this is really only the case when the lighting changes, or I want a different style of photo such as a different depth of field.  Finally, does exposure change with distance to the subject? For example say I want to take a picture of a statue with correct exposure using a gray card. I'd place the card on the statue, and while being careful not the block the light on the card find the correct exposure by spot metering the card. If I were then to step back 20' to get the whole statue in frame would I still have the correct exposure? is looking bad right now. No errors in the console, but the following files have no content:         The CSS on another subdomain works fine though: What are good ways to make pdflatex output copy-and-pasteable? One frequent aspect of pdflatex output that could be improved is to what extent one can select text output from the generated pdf-file and copy-and-paste it. This is essentially an issue of having the right output encoding. There are at least two important aspects to this:   In the ideal case, Unicode would be the output encoding. Ligature glyphs (such as ﬁ) are ideally de-ligated in the output (here: "fi").   It seems that output encodings are specified through the fontenc package. What is the range of possible output encodings, and most importantly: Is there a way to specify a Unicode output encoding and one that deals with ligatures in the intended way?  (Note: It is important to distinguish output from input encodings. How to use different input encodings in LaTeX has been documented widely. My understanding is that this is best handled by the inputenx package, as it supersedes the inputenc package.)    Quick guide to the solutions: The information in the answers and answer threads is a bit distributed, so here the short summary: one approach is to use \input glyphtounicode together with \pdfgentounicode=1; the other approach is to use cmap/mmap.  Addendum: Sometimes one will need to load the package accsupp and enclose one's macro definition in \BeginAccSupp{method=hex,unicode,ActualText=&lt;codepoint&gt;}[...]\EndAccSupp{} to generate a specific code point. See the caveat about non-BMP code points  and the fix (starting from accsupp version v0.4, 2012/11/18) , which provides the new unichar package option. In the season 8 episode finale of Game of Thrones the highest important lords met with Grey Worm to free      Tyrion and Jon. While it was pretty clear why they wanted to free Jon it was unclear to me why they also asked for Tyrion.   To make things even more strange, they asked about his opinion of a potential solution which becomes the actual final one in the end      (choose king and nominate someone).   I thought they (besides Sansa and Bran) don't like him and wanted to judge him? Or am I missing something? I've got a secondary harddrive (a separate physical device, not a logical partition) specifically dedicated for the Virtual Memory paging file.  The drive is 3.5x larger than my RAM, so it's plenty large.  When I configure Windows 7's virtual memory to put the paging file on this second harddrive and not the same drive as the operating system, I'm warned,     If you disable the paging file or set the initial size to less than 800 megabytes and a system error occurs, Windows might not record details that could help identify the problem. Do you want to continue?   So in other words, if I get a Blue Screen of Death, I won't be able to investigate why, just because I put my paging file at a more efficient location.  The best explanation I can find from searching the web is that Windows just doesn't want to make error dumps on a drive separate from the operating system location.  Can anybody give me a less nonsense explanation for this?  I don't want to have to tell Windows, "Sure, go ahead and continue managing a paging file on the primary drive," just so I can get a debug dump, as that totally defeats the purpose of a physically separated paging file.  Is there a workaround to having my paging file on a separate drive and still get error dumps? Merging Raster Datasets of Different Resolutions using ArcGIS Desktop? I am using ArcGIS Desktop.  I have two DEMs in .tif format and I am looking to merge the two. The main problem with merging these are that they are different resolutions (one is 10m and one is ~20m). Also, another problem with merging the two is that they overlap and I am not sure of the most effective way of dealing with that overlap. Obviously I want to keep the values of the better resolution.   So what are the best methods here?   Is there a python script available that works best with merging rasters? I would like to automate this with a script if possible. Which process of resampling is best for DEM data? Bipolar, Cubic... ? What is the best way to merge overlapping DEMs? Sum and Product of Infinite Radicals What is the remainder when $1! + 2! + 3! +\cdots+ 1000!$ is divided by $12$? What is the remainder when $$1! + 2! + 3! +\cdots+ 1000!$$ is divided by $12$.  I have tried to find the answer using the Binomial Theorem but that doesn't help. How will we do this?  Please help. I've been wondering, what is the difference between seek and search?

Emulate "double" using 2 "float"s Prior to doing some benchmarking work how would one free up the memory (RAM) that the Linux Kernel is consuming for its buffers and cache?    Note that this is mostly useful for benchmarking. Emptying the buffers and cache reduces performance! If you're here because you thought that freeing buffers and cache was a positive thing, go and read . The short story: free memory is unused memory is wasted memory. 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. Apply display settings to all user accounts? Has Marvel commented on the extra Infinity Gauntlet?
