How can i hide the references lines on a bezier curve?
Is it possible to hide curves' guides in edit mode?
Differences between astronomy, astrophysics and cosmology? When I use the listings package with frame in my code the frame "breaks" when the page ends and it is open in the end of the page. I want the frame to be complete with four sides and continue in the next page again with all four frame sides complete. How can I do this? Why does the frame "breaks"? Is there any scrappable junk I should hold on to that could otherwise be used for other purposes? Let $a,b$ be positive integers such that $a\mid b^2 , b^2\mid a^3 , a^3\mid b^4 \ldots$ so on , then $a=b$? Let $a,b$ be positive integers such that $a\mid b^2 , b^2\mid a^3 , a^3\mid b^4 \ldots$ that is $a^{2n-1}\mid b^{2n} ; b^{2n}\mid a^{2n+1} , \forall n \in \mathbb Z^+$ , then is it true that $a=b$ ? I don't understand, because if 'don't' is 'do not' then wouldn't the sentence without conjunctions be 'do not you dare' which I'm pretty sure isn't grammatically correct. Like, when we say the term it means something else, certainly not 'do not you dare' anyway. Any ideas on why? I am so glad English is my first language. Insert into ... values ( SELECT ... FROM ... ) I am trying to INSERT INTO a table using the input from another table. Although this is entirely feasible for many database engines, I always seem to struggle to remember the correct syntax for the SQL engine of the day (, , , , and ).  Is there a silver-bullet syntax coming from an SQL standard (for example, ) that would allow me to insert the values without worrying about the underlying database? I have a battery pack of NiMH batteries. It is ten cells with 1.2V, 4000mAh each, put together in series. So rated voltage is 12V. After charging, i.e. when the charging device says that it is finished, I measure 14.3V.   When I now discharge, at what voltage should I consider my battery as "empty"? Is this the lowest voltage that I can discharge it to without damaging it? Which voltage is that? How do I call one constructor from another in Java? I need to construct a real function with is exactly $C^2$ (that is, it is continuous and two times differentiable but it is not three times differentiable) such that its first derivative never vanishes.  I tried  $x^5 \sin(\frac{1}{x}) + \exp(x)$  $x^{\frac{5}{2}} + \exp(x)$  ${|x|}^3 + \exp(x)$  all these functions are exactly $C^2$, but their first derivatives vanish in some point(s). :( I was loading an image resource with the following code and it works fine from my dev environment (netbeans) but threw an exception as soon as it ran from the desktop.  new ImageIcon(Images.class.getResource("images/highlighter24.gif"));   I traced it down to my file having different case than in the code.  Fine, my bad, but why the inconsistent behavior?  Gremlins?  Note: I'm running on windows before you ask. Singular or plural verb after parenthetical material containing a conjunction? I would tend to say     Sara (and all of us) have a lot to think about now.   ...but it occurs to me that if I remove the parenthetical it's clearly incorrect. Is it proper to say     Sara (and all of us) has a lot to think about now.   ...that sounds really strange to my ear.  Also, does it change the rules in any way if I use an em dash, e.g.     Sara–and all of us–have a lot to think about now. What are the 'types' of parametric down conversion? Determining ethnicity according to ancestry? My sister, cousins, and other relatives speculate that my mom's grandmother was Jewish (for various reasons). I've heard people say at times things like, for example, "I'm 50% German" or "I'm 25% Swedish." This has to do with their ancestry. But, how exactly is this calculated? Say for example that my mother's paternal grandmother was indeed 100% Jewish, what would that make me and my siblings, and how is it calculated? Why can't I find a USB-C hub with multiple USB-C ports? My computer only has one USB-C port and I want to connect multiple USB-C devices to it.  I have trawled through Amazon but am amazed that I cannot find a single one. There are many hubs that have USB 3.1 USB-A ports but not USB-C ones.  Is there a limitation in the spec that prevents this being possible? What do we lose passing from the reals to the complex numbers? As normed division algebras, when we go from the complex numbers to the quaternions, we lose commutativity. Moving on to the octonions, we lose associativity. Is there some analogous property that we lose moving from the reals to the complex numbers? os.path.abspath("..") returns "C://User//" which is false + __file__ is not defined --> execution from Spyder3 (Python 3.6) I was looking for some package (nautilus-terminal), and accidentally did this:  $ sudo apt-get install nautilus- Reading package lists...

Rails Previous Sunday in Relation to Any DateTime How does the bounty system work? Proving that cardinality of the reals = cardinality of $[0,1]$ Homework problem, intro to topology. Here's what I've done so far. Am I on the right track? And, how would you advise me to proceed from here?  I have already established that $\left |[0,1] \right | = \left |[0,1) \right|$. Now I wish to show that $\left |[0,1) \right| = \left |\mathbb{R} \right |$. I will try to do this by constructing a bijection $f: [0,1) \rightarrow \mathbb{R}$.  Given $x \in [0,1)$, consider the following countably infinite subset of $\mathbb{R}$: $x^c = \{x+1, x-1, x+2,x-2,x+3,x-3,\ldots   \}$.  Then we have that $$ \bigcup_{x \in [0,1)} x^c = \mathbb{R}, $$ and if $x_1, x_2 \in [0,1)$ with $x_1 \neq x_2$, then $x_1^c \cap x_2^c = \varnothing$.
