How to upgrade python from 3.5.2 to 3.6.2 via terminal?
I want the very latest version of Python, but I don't want to bypass the apt package manager: I don't want to do an old-school source install because that can make it harder to uninstall when the official packages come out.  Python3.5 is not currently featured in any of Canonical's package repositories, which means I cannot just "apt-get install python3.5".  Is there a way to get Python3.5 installed on my PC in the meantime?
How do I turn off equation auto numbering Familiar form of address for a young, subordinate, woman that connotes respect (Female equivalent to 'Son') A(n often male) paternal figure could use the term 'son' in a fatherly way without referring to his biological Son.  Imagine a man has been verbally abused by a customer at work. His manger might say to him:     Come here son, I have something to tell you   about rude customers   Emphasis on the word I want gender-swapped  Is there a feminine equivalent for a subordinate that you respect?   From      son  (sŭn)   n.    1. One's male child.    2. A male descendant.    3. A man considered as if in a relationship of child to parent: a son of the soil.    4. One personified or regarded as a male descendant.    5. Used as a familiar form of address for a young man.    6. Son Christianity The second person of the Trinity.     Is there an equivalent for talking to a woman in a fatherly way?  The equivalent for TFD entry for daughter does not qualify it as 'familiar'        (often capital) a form of address for a girl or woman      Further more often such 'father-daughter' language patterns are negative, dismissive and lack respect.

How can I create a text input box with Pygame? Issue with 'StringVar' in Python Program Why did the quality of terminators increase from movies 1 to 3? I have seen only the first three movies, so I don't know whether the other movies/TV series deal with this question or not. My main point is that in the movies, the terminator that travels back furthest in time is of the worst quality, and the quality increases with the time travel (meaning they travelled from a later time). What is a good explanation for this?  Note: I am not interested in the obvious not-in-universe explanation that they wanted something better and bigger for each new movie. Is the use of a hyphen between "non" and an adjective strictly necessary? Do I need to put a "-" between "non" and an adjective? As an example in physics we say "a non isolated photon", "non tight photon"... The context is very formal (paper publications and similar). Is there a general rule? Are there some differences between countries? Can someone tell me how to get a closed form for  $$\sum_{k=1}^n k^p$$  For $p = 1$, it's just the classic $\frac{n(n+1)}2$.   What is it for $p &gt; 1$? Continuously Differentiable Curves in $\mathbb{R}^{d}$ and their Lebesgue Measure Show that the image of the curve $\Gamma\in\mathscr{C}^{1}\left([a,b]\to\mathbb{R}^{d}\right)$ has d-dimensional Lebesgue measure zero (of course, $d\geq2$).  This can be proved using the absolute continuity of $\Gamma'$ (since $[a,b]$ is compact and $\Gamma'$ is assumed continuous, hence in $L^{1}([a,b])$) together with the fundamental theorem of calculus to obtain an $\epsilon$-small cover of $\Gamma$ by balls.  But I am trying to prove this using more elementary means (i.e. without integration).  Intuitively, since $\Gamma$ is smooth, we ought to (for fine enough partitions) be able to cover $\Gamma$ by boxes which arise from its tangent line.  And by taking the partition of $[a,b]$ to be finer and finer, the "tangent box" cover ought to also get smaller and smaller.  More rigorously, the vector-version of the mean value theorem can be applied: $$|\Gamma(t_{i-1})-\Gamma(t_{i})|\leq(t_{i}-t_{i-1})|\Gamma'(t_{i}^{\star})|\leq M_{i}\Delta t$$ where $t_{i}^{\star}\in(t_{i-1},t_{i})$ and $M_{i}=\sup_{t\in[t_{i-1},t_{i}]}|\Gamma'(t)|$ which exists and is finite since $\Gamma'$ is continuous.  But to me, it's not quite clear how to rigorously construct a cover by boxes from here.  NOTE:  In the proof I mentioned (using integration), essentially you sum the left hand side over all partition intervals of uniform length $\delta$ (which depends on the $\Gamma'$), and "integrate" the right hand side.  Actually, to be more specific, for each $\epsilon&gt;0$ there exists a $\delta&gt;0$ such that $||P||&lt;\delta$ implies $\int_{t_{i-1}}^{t_{i}}|\Gamma'(t)|dt&lt;\epsilon$ (e.g. absolute continuity).  This allows you to define numbers $\epsilon_{i}=\sup_{t,\bar{t}\in[t_{i-1},t_{i}]}|\Gamma(t)-\Gamma(\bar{t})|\leq\epsilon$ so that $\sum_{i=1}^{\#P}\epsilon_{i}\leq||\Gamma'||_{L^{1}([a,b])}$.  Then you can use these $\epsilon_{i}$ to put balls at each point $\Gamma(t_{i})$ of radius (say) $2\epsilon_{i}$, thus giving you an $\epsilon$-small cover.  Again though, this is harder to establish without integration theory. When should end punctuation go inside quotes? Formula Error: Syntax error. Extra ',' I am trying to write a formula for opportunities but I keep getting the following error   Error: Syntax error.

While doing some upgrades to custom software I did not notice that the line endings in some scripts were Windows version (CR+LF) and not the Unix version (LF). So now when I want to launch the script it gives an error:   bash: /usr/local/bin/portsee: /usr/bin/python^M: bad interpreter: No such file or directory   Is there a way to change all line endings in a script from terminal. The thing is that I can not install any new software to this group of PC-s. I am trying to under stand how to build a barrel shifter using multiplexers. I understand how the barrel shifter works but I don't get how you decide the number of multiplexers to use, and how the shifting is done with the multiplexer basically.  So far wikipedia doen't help much. And the best I have so far is   But it does not really answer my question. Workflow for converting LaTeX into Open Office / MS Word Format Perpendicular Chord parabola If $r_1,r_2$ be the length of the perpendicular chords drawn through the vertex of a parabola $y^2=4ax$, then show that $$(r_1r_2)^{4/3}=16a^2(r_1^{2/3}+r_2^{2/3})$$ What are the most widely used C++ vector/matrix math/linear algebra libraries, and their cost and benefit tradeoffs? How can I ensure my Samsung Series 7 is actually using the Radeon switchable graphics? I have a Samsung Series 7 with the Radeon 6750M switchable graphics. The ATI software lets you force programs to use the dedicated card. However, I'm not convinced it is actually ever using it, as the frame rates on some non-taxing games (Portal, TF2) are merely OK. To make matters worse, it looks like the ATI Catalyst Control has vanished from my laptop. To make it even worse, you can't download the driver and ATI CCC from ATI's site, you need to download it from Samsung, and the ZIP they provide is corrupted.   How can I ensure my Samsung Series 7 is actually using the Radeon switchable graphics? What is an example of Gâteaux differentiable but not Fréchet differentiable at a point in a finite-dimensional space? Let $V,W$ be nonzero normed spaces over $\mathbb{K}$ such that $V$ is finite-dimensional.  Let $E$ open in $\mathbb{K}$ and $p\in E$.  Let $f:E\rightarrow W$ be Gâteaux-differentiable at $p$.  Is $f$ necessarily Fréchet-differentiable at $p$ in this case?  I think this is not true in general, but cannot find a counterexample. What would be a counterexample? I want to typeset a piece of code containing line breaks.  New lines should indent to a specified point in the previous line.  Here is a monospaced example to illustrate what I mean.  Notice how 'case' and 'of' line up below, as well as 'let' and 'in':  swap : forall a, b. Tuple a b -&gt; Tuple b a swap a b x = case x              of tuple a b y z. let x' = tuple b a z y                                in x'   The code I want to typeset is not monospaced, so I can't just use a verbatim environment to get what I want.  The actual LaTeX of the first line, for instance, is  \mathsf{swap} : \forall\alpha,\beta.\;\mathsf{Tuple}\;\alpha\;\beta\to\mathsf{Tuple}\;\beta\;\alpha   How can I align some text to a specific point in the previous line? How do you create a dropdownlist from an enum in ASP.NET MVC? I'm trying to use the Html.DropDownList extension method but can't figure out how to use it with an enumeration.  Let's say I have an enumeration like this:  public enum ItemTypes {     Movie = 1,     Game = 2,     Book = 3 }   How do I go about creating a dropdown with these values using the Html.DropDownList extension method?  Or is my best bet to simply create a for loop and create the Html elements manually?
