Task unrolled loop behavior
Captured variable in a loop in C#
Is this WUBI? What is "Installation size" setting for? I'm new to Ubuntu... I went to the downloads page and downloaded the Windows Installer as I am hoping initially to have a dual boot on my currently Win 7 PC (I would consider preserving my Win7 install as a VM under Ubuntu instead - advice?)  It's asking me to choose an "Installation size" but there's no explanation as to what the significance of this is. Is this a disc partition?  Can I increase it easily later if it's too small?  I came here to ask these questions and now I see a bunch of threads about 'WUBI' and possible downsides of installing Ubuntu this way. Is the Windows Installer I just downloaded going to give me WUBI? Are the decimal places in a CSS width respected? How to integrate $\int\sqrt{x^2+1}dx$ What is the result of $ \lim_{n \to \infty} \frac{ \sum^n_{i=1} i^k}{n^{k+1}},\ k \in \mathbb{R} $ and why? What is the result of the next limit:   $$ \lim_{n \to \infty} \frac{ \sum^n_{i=1} i^k}{n^{k+1}},\ k \in \mathbb{R} $$  Why (theorem)? How do I find the current machine's full hostname in C (hostname and domain information)? In a C project (POSIX), how do I get the fully qualified name for the current system?  For example, I can get just the hostname of my machine by doing gethostname() from unistd.h. This might give me machine3 in return, but I'm actually looking for machine3.somedomain.com for example.  How do I go about getting this information? I do not want to use a call to system() to do this, if possible. I use object != null a lot to avoid . What is an alternative to: if (someobject != null) {     someobject.doCalc(); } What motivates people to answer questions in Stack Overflow? I want that too - motivation to answer programming-related questions. What is yours? Why do people buy stocks that pay no dividend? Modernist Cuisine recommends that for longer sous vide cooking (times greater than 36 hours) that bags are vacuum sealed rather than just using the water displacement method to remove the air from a ziploc bag.  What is the reason for this? Will I be losing something essential if I just use a regular ziploc bag without vacuum sealing? Hydrostatic pressure - doesn't density vary with depth? Our class is learning about hydrostatic water pressure and we have been told that we can calculate the force of the liquid on an object at any depth using "the density x 9.8 x the depth". However, as the depth increases, wouldn't the density of the liquid increase because of the weight of the liquid above it compressing it? So should't there be something in the equation to account for the varying density? To me, "density x 9.8 x depth" seems like it is saying that the density will be constant... Physics history book with some math I am looking for a book explaining physics from, say, Galileo and Newton till now; the book should be written using some math, similarly to my physics books when I was at the university (Halliday Resnik). I am searching a book that take care of explaining the true "evolution" of reasoning, discoveries, experiment to prove or disprove something.  I do not like a book that gives definitions without explaining what had happened. I also like to find, on that book, explanations on how actual measurements are taken (how can we measure the speed of light, the mass of celestial bodies, the attributes of electron, and how were the measurements taken in the past - how was possible to measure the speed of light in 1700-1800?).  I am not very interested in recent theories like strings, branes.... so it is OK if these are not discussed.  I like to find a lot of discussions on concept that are related, like for instance the implications on space dimensionalities, ether non-existence, strange facts, missing explanations. Let's take the numbers 0-10.  Their mean is 5, and the individual deviations from 5 are -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5 And so the average (magnitude of) deviation from the mean is $30/11 \approx 2.72$.  However, this is not the standard deviation.  The standard deviation is $\sqrt{10} \approx 3.16$.  The first mean-deviation is a simpler and by far more intuitive definition of the "standard-deviation", so I'm sure it's the first definition statisticians worked with.  However, for some reason they decided to adopt the second definition instead.  What is the reasoning behind that decision? How to hide a(n) (NTFS) partition from ubuntu I need to hide an NTFS partition from listing in the nautilus. How can I achieve that?   Is there any tool to do that?   And how can I hide files in ubuntu (except . operator) how to hard-bypass the input of a line driver with a switch? It seems that the question has eventually become a series of questions....    An example goes as:     The 1st and (the) 2nd paragraphs of the article are extremely long.   Another example:     What are the situation, (the) task and (the) result of your story?   Is it necessary to use the in ()? Variational Derivation of Schrodinger Equation Sometimes (old) comments break the parser, so it would be nice to view their code to check what was (actually) supposed to be there. Is there any way to view a comment's source just like the source link in a post's revision?  edit Another application for this would be the ability to better quote comments in an answer without having to re-markdown them. Anyone seen this one yet? Vote too old to be changed, unless post is edited My vote was only a few hours old. Then I realized the answer was wrong. Updated my question and went to remove the vote. Even after updating question I still have the issue. Small issue, but frustrating.

And how can you calculate the values of $k$ and $m$?      Thank you in advance.
