best version for r15-s829 toshiba satellite i recently picked up a toshiba satellite r15-s829 at my local pawn shop and while i do love this little guy, im hoping that going back to ubuntu will make him better. i need to know which version of ubuntu is the best option and whether or not the tablet functions will work as i got this with the intent of being for my 3d modeling tasks and because i like the old school analog note taking features of the tablet pen function.
How do I find out which version and derivative of Ubuntu is right for my hardware in terms of minimal system requirements? For a given hardware configuration, how do I find out if Ubuntu will run on it? What considerations should I take into account when choosing an Ubuntu version and  such as:    with a lighter desktop than the usual Gnome and Unity  with the even lighter LXDE desktop   Obviously Ubuntu does not run on some processor architectures. So how do I go about choosing the right version and derivate. How can I find out the minmal system requirements?
Is is possible to move all windows (or all not minimized windows) form one workspace to another?   I know I can move one window to other workspace with Shift+Ctrl+Alt+arrow, but it will move only that one focused window. Reading order for Cosmere series by Brandon Sanderson My entry into Brandon Sanderson's works is Mistborn Trilogy, I finished and loved it. Then I got to know that many of his series are connected and happen in the same universe - Cosmere. Next I started with the Way of Kings, but am now kind of worried if I might read the series in the wrong order. So what is the right order to read them? is it the publication order..?   Elantris (2005)  Mistborn Trilogy Warbreaker (2009) The Stormlight Archive: The Way of Kings (2010) Mistborn: The Alloy of Law (2011) The Emperor's Soul (2012, novella) Shadows for Silence in the Forests of Hell (2013, short story published in Dangerous Women) The Stormlight Archive: Words of Radiance (2014)    or I have seen people suggest the following order too,   Mistborn Trilogy Elantris and the Emperor's Soul The Way of Kings Warbreaker Words of Radiance The Alloy of Law Shadows of Self   I have also read posts where they say it doesn't matter which order you read it in. So am confused, since I have already started the Way Of Kings (Only a few chapters in), should I stop it and go back to Elantris, and follow an order, or should I just continue finish this and pick other books in an order. Excuse me if the question is naïve. I am not a physicist.  Let's imagine formation of a black hole from a homogeneous collapsing star. At certain moment when enough of matter is inside of a small enough spherical area the event horizon starts to exist. When does the singularity start to exist and why?  The matter below the event horizon still continues to collapse towards the centre (e.g. in the reference frame of the falling matter). What are the necessary conditions for the singularity to appear?  I have found two similar questions but the answers did not really explain this problem to me: Cannot get onto Apple Developer Forums Every time I attempt to log on to the apple developer forums it tells me I need to create a new user account (even though I already have one), and when I try to sign up it gives me an error:   Anyone else have this issue and/or know how to fix it? Thanks! There are two schools of thought on how to best extend, enhance, and reuse code in an object-oriented system:   Inheritance: extend the functionality of a class by creating a subclass. Override superclass members in the subclasses to provide new functionality. Make methods abstract/virtual to force subclasses to "fill-in-the-blanks" when the superclass wants a particular interface but is agnostic about its implementation. Aggregation: create new functionality by taking other classes and combining them into a new class. Attach an common interface to this new class for interoperability with other code.   What are the benefits, costs, and consequences of each? Are there other alternatives?  I see this debate come up on a regular basis, but I don't think it's been asked on  Stack Overflow yet (though there is some related discussion). There's also a surprising lack of good Google results for it. If the sum of $n$ cubes is zero, then the sum must be no larger than $\frac n3$. Assume that $a_1,...a_n$ are real numbers and $-1 \leq a_i\leq 1$ for $1\leq i\leq  n$. If $$a_1^3+\ldots +a_n^3=0$$ Then show that $$a_1+a_2+\ldots+a_n\le n/3$$   I just came cross this problem the other day. I totally have no idea how to prove it. Are there any hints about which theorem, principle or method to apply? Proof of Russian Peasant Multiplication I'm studying a combinatorics text () in preparation for taking discrete math this upcoming semester. I've taken a fair amount of math in college, through Calculus II, but this is my first 500+ level math course.    In chapter 2 of the  book, the author introduces an algorithm for multiplication called Russian Peasant Multiplication. I want to prove that this algorithm will always result in the product of two numbers.  I've been chewing on the proof for a while now, and just can't seem to get any traction. Thanks in advance for any help.  Description of Algorithm  I'll try to explain the algorithm clearly. The goal of the algorithm is to find the product of two numbers $m$ and $n$. The below table is filled out for $m$ and $n$:  $$\begin{array}{c} m&amp;&amp;n&amp;\\ \hline \bigl\lfloor \frac{m}{2} \bigr\rfloor&amp;&amp; 2n \\ \bigl\lfloor \frac{m}{4} \bigr\rfloor&amp;&amp; 4n \\ \bigl\lfloor \frac{m}{8} \bigr\rfloor&amp;&amp; 8n \\ \bigl\lfloor \frac{m}{16} \bigr\rfloor&amp;&amp; 16n \\ \bigl\lfloor \frac{m}{32} \bigr\rfloor&amp;&amp; 32n \\ \end{array}$$  The sequence of numbers in both columns is the sequence $a_n = 2a_{n-1}\text{ where }a_1=2$. The columns are extended down until the value in the left column is equal to the number one. After filling out the table, the product is found by adding the values of the right column where the left column is an odd number.  For example, to multiply 18 and 37 with the algorithm:  $$\begin{array}{c} m&amp;&amp;n&amp;\\ \hline 18 &amp;&amp; 37 \\ 9 &amp;&amp; 74 \\ 4 &amp;&amp; 148 \\ 2 &amp;&amp; 296 \\ 1 &amp;&amp; 592 \\ \end{array}$$  To find the product, cross out values of the left column where the value of the right column is even:  $$\begin{array}{c} m&amp;&amp;n&amp;\\ \hline \require{enclose} \enclose{horizontalstrike}{18} &amp;&amp; \enclose{horizontalstrike}{37} \\ 9 &amp;&amp; 74 \\ \enclose{horizontalstrike}{4} &amp;&amp; \enclose{horizontalstrike}{148} \\ \enclose{horizontalstrike}{2} &amp;&amp; \enclose{horizontalstrike}{296} \\ 1 &amp;&amp; 592 \\ \end{array}$$  And add the remaining numbers in the right column to get the result: $18\times37=74+592=666$  Alternate Description of Algorithm  As an aside, here is a shorter way to describe the algorithm, repeat the below steps until the left column == 1:  • Halve the last number in the first column • Write the result below (discard the remainder) • Double the last number in the first column. • Write the result below.   Now, for every even number in the first column, delete the adjacent number in the second column. Add the remaining numbers in the second column.  What I've done so Far  I haven't been able to get much of anywhere on the proof. One thing I did was create a bit of a different way of arriving at the same outcome:  $$\begin{array}{c} m&amp;&amp;n&amp;&amp;\text{index}&amp;&amp;\text{remainder}&amp;&amp;\text{if remainder == 1, }n\times2^{Index}&amp;\\ \hline 18 &amp;&amp; 37 &amp;&amp; 0 &amp;&amp; 0 \\ 9 &amp;&amp; 74 &amp;&amp; 1 &amp;&amp; 1 &amp;&amp; 74\\ 4 &amp;&amp; 148 &amp;&amp; 2 &amp;&amp; 0 \\ 2 &amp;&amp; 296 &amp;&amp; 3 &amp;&amp; 0 \\ 1 &amp;&amp; 592 &amp;&amp; 4 &amp;&amp; 1 &amp;&amp; 592\\ \end{array}$$  Which brings to light the relationship between this algorithm and binary numbers (the fourth column in the above table is the product in binary, read bottom to top).   I also wrote some Python functions to help me explore the problem, Dual boot UEFI Windows 7 and Ubuntu 12.04 (both 64 bits). W7 entry doesn't appear in GRUB TestMethod do not support Web service callouts, test skipped Q: "Do you have any juice?"   A: "Yes, there's some in the fridge."   Sounds perfectly fine to me, but:     Q: "Do you have any towels?"   A: "Yes, there's some in the closet."   Does not.  I asked for towels - plural - so wouldn't "Yes, there're some in the closet," in which there are is turned into a contraction be the correct way to say it?  Spellcheck, however, doesn't like "there're", and I think I'm the only person I've ever heard use the word "there're".  Even folks who I know say "there are" shorten it to "there's" when possible.  Am I saying it wrong, or are both forms acceptable? Tags on badge question list I'm trying to get the Weed-Eater hat on Stack Overflow. To do so, I'm looking at the list of questions . The problem is, no tags show up there, and so it's rather difficult to see which ones I have a shot at. Any chance of showing the tags on this page?  I realize that getting this before Winter Bash is over would be difficult, but it would be good to keep such things in mind for the future. If it was possible to dig a hole that went from one side of the Earth to the other... Fspy add-on not installing In a few large projects i have been working on lately it seems to become increasingly important to choose one or the other (XML or Annotation). As projects grow, consistency is very important for maintainability.   My questions are: what are the advantages of XML-based configuration over Annotation-based configuration and what are the advantages of Annotation-based configuration over XML-based configuration? I have 3 fields ( Exposed filter ) 1 Country 2 State 3 City  When a respective Country is selected in the 1st field, I want the second filter ( Dropdown or autocompete ) to display states of the country selected in the 1st field &amp; when this is done based on the state selection , I want the 3rd field to show only the cities belonging to the state selected in the second field.  How can this be done ? any help ? I want to start using the terminal more often, but I don't know what are the different commands available to me. Is there a way to list all the different commands that I can make use of? The prepositions “with”, “at” and “for” are also used to associate a business title with a company's name. It seems that they are interchangeable, with no (significant) difference in meaning. The following examples taken from The New York Times website seem to confirm that:      Until now, said Justin Nielson, a senior analyst for the media   research firm SNL Kagan, “there really hasn't been any direct   competitor . . .      “The consumer is still deleveraging,” said Jason Goldberg, a senior   analyst with Barclays. “It's not a lack of supply; it's a lack of   demand.”      “There’s the party of fear and the party of despair,” Nikos Xydakis, a   political analyst and an editor at Kathimerini daily, said.   Are they really the same as for meaning? If it isn't so, what is the difference between them? Double integral of an function odd with respect to $y$ over a domain symmetric with respect to $x$ axis Let $D$ be a region given as the set of $(x, y)$ with $$a \leq x \leq b\quad\text{and}\quad-\Phi(x) \leq y \leq \Phi(x)$$ where $Φ$ is a nonnegative continuous function on the interval $[a, b]$.  Let $f(x, y)$ be a function on $D$ such that $$f(x, y) = - f(x, - y)$$ for all $(x , y) \in D$.  Argue that $$\displaystyle \iint_D f(x, y) dA = 0.$$ What happens when a field turns on or off? Short Setup  I am curious about the the mechanics of fields, whether , , etc.  So as a specific example in order to simplify (hopefully) how to ask this question, consider  or , specifically interactions between .  My specific curiosity is in how we handle the "sudden" creation or loss of a source and how the source then creates its associated field.  My naive guess is that the loss of a source (e.g., annihilation) might be easier to handle, but let's focus on creation of a source for now.  Questions  The specific example of pair production interested me because I was wondering:   How does the field arise from the sources?   Meaning, is it delayed until after the source  fully "condenses" from the , for instance? Or does the field slowly "turn on" as the source "condenses"?   Perhaps I should have asked whether it we know if it takes time for sources to form (I assume it does).  If so, can we describe this from first principles or is it empirically based?  Am I asking that in a very uncomfortable manner?  If so, I would appreciate any suggestions.  For instance, is there a better word than "condense"?  I was thinking about water condensation as a very loose analogy to the purpose of the Higgs field in the formation of massive objects.  Why can they be produced without immediately recombining?   That is, how "close" are the two sources spatially after formation and what energies are needed to overcome the associated potential?  Does the field emanate/propagate as if from a point source?   I ask because I am trying to determine whether this is a simple  issue (i.e., far away it's just like a point source) or if the field emanates only from the "surface" of the source (e.g., ). If it starts from "within" the source as the source forms, do we know how to handle this mathematically?   My concern arises from the "similar" problem of bubble formation, where the bubble starts with zero radius which would require an infinite energy.  Perhaps the analogy is not appropriate?     Purpose  I ask these questions because it struck me this morning, while driving to work, that I did not know how and when a field "turned on."  I started to think about pair production and then quickly became confused (not difficult to do) and thought many of the quantum whisperers on this site would be much better at explaining these nuances than any of my failed rummaging through Wikipedia or scholarly articles and old text books. I was just wondering how can you use "there is" followed by a word that is in plural, e.g  "There's cupcakes in the fridge"  and  "There is a couple of things we can do --"   Is it just slang?
