In a situation when I talk with someone about setting up a schedule, can we use "totally" with a phrase like the title? I know that the meaning of totally itself is basically used for emphasizing the expression. And I also know that completely sounds more polite and also a little old.　But what I just want to know is whether native speakers use "totally" in this kind of situation or not. Does it sound normal? Or do you have some other better suggestions?
There was the following sentence in an article titled, “Like, Degrading the Language? No Way” in New York Times (April 5), in which the author says Americans are moving backward on language:     “(Like the use of ‘like’) the use of “totally” mines the same vein.   “He’s totally going to call you” does not mean “He is going to call   you in a total fashion.” It has a more specific meaning, although only   handled subconsciously by speakers, as so much of language is. “He’s   totally going to call you” contains an implication: that someone has   said otherwise or that the chances of it may seem slim at first glance   but in fact aren’t. As with “like,” “totally” tracks and nods to the   opinions of others. It’s totally civilized.”      Although the author explains “totally going to call you” contains an implication of someone having said otherwise, I’m not still clear with the meaning of “He’s totally going to call you.”   What does it mean? He’s totally going to call you “what”?   How does “He’s totally going to call you.” differ from “He’s going to call you.”? Is this expression (use of totally) ubiquitous today as the author asserts?
Automatic vacuum fails with `ERROR: XX000: cache lookup failed for type 0` I've been noticing something like this popping up every 15 seconds in my server logs:  2020-01-30 21:10:30 UTC::@:[24969]:ERROR: XX000: cache lookup failed for type 0 2020-01-30 21:10:30 UTC::@:[24969]:CONTEXT: automatic vacuum of table "myschema.mytable" 2020-01-30 21:10:30 UTC::@:[24969]:LOCATION: get_typlenbyval, lsyscache.c:2036   When I manually run a VACUUM ANALYZE myschema.mytable; it runs without any error, and the error in my logs goes away.

Okay, maybe I'm missing something obvious but consider $h_n(x) = x^{ 1+ \frac{1}{2n-1}}$ on the set $[-1,1]$. Now consider a fixed $x \in [-1,1]$, we have:  $$\lim_{n\rightarrow \infty} h_n(x) = x \lim_{n \rightarrow \infty} x^\frac{1}{2n-1} = x$$  But my book says it's $|x|$? Why?

For example, I have a guide line named A already. After that, I want to have another guide named B  parallel with guide A and at 50px distance from it.   I have three solutions:   Draw line B and by "some way", I can see the current distance directly when I'm drawing, so I can make the distance exactly what I want it to be.  Draw line B. And then I use the Ruler tool to see the distance between the two guides. This method has disadvantages: maybe the ruler line that I draw isn't perpendicular with the guides and I'm not sure when the distance is enough. There are other clever ways, that help me get this job done fast and easily, but that I don't know yet. I think Photoshop should support this feature.   What is the best way to achieve this? How do I check if an element is really visible with JavaScript? In JavaScript, how would you check if an element is actually visible?  I don't just mean checking the visibility and display attributes. I mean, checking that the element is not   visibility: hidden or display: none underneath another element scrolled off the edge of the screen   For technical reasons I can't include any scripts. I can however use  as it is on the page already. Can you show me a continuous function $f \colon \mathbb{R}^n\to\mathbb{R}^m$ that satisfies $f(a+b)=f(a)+f(b)$ but is not linear?   We have that  $$f(0)=f(0+0)=2f(0)\implies f(0)=0\\ f(x-x)=f(0)=f(x)+f(-x)=0\implies f(-x)=-f(x)\\ f(nx)=f(x+x+\dots+x)=f(x)+\dots+f(x)=nf(x)\quad \forall n \in \mathbb{N}$$ But $$ f(-nx)=-f(nx)=-nf(x) $$ So: $$ f(ax)=af(x) \quad \forall a \in \mathbb{Z} $$ Legitimate edits of less than 6 characters I have a question about deriving the coordinate representation of momentum operator from the commutation relation, $[x,p]= i$.  One derivation (ref W. Greiner's Quantum Mechanics: An Introduction, 4th edi, p442) is as following: $$ \langle x|[x,p]|y \rangle = \langle x|xp-px|y \rangle = (x-y) \langle x|p|y \rangle. $$ On the other hand,  $ \langle x|[x,p]|y \rangle = i \langle x|y \rangle = i \delta (x-y)$. Thus $$ (x-y) \langle x|p|y \rangle = i \delta(x-y). \tag{1} $$  We use $(x-y) \delta(x-y) = 0$. Take the derivative with respect to $x$; we have $\delta(x-y) + (x-y) \delta'(x-y) = 0$. Thus $$ (x-y) \delta'(x-y) = - \delta(x-y). \tag{2} $$  Comparing Eqs. (1) and (2), we identify $$ \langle x|p|y \rangle = -i \delta'(x-y). \tag{3} $$  In addition, we can add $\alpha \delta(x-y)$ on the right-hand side of Eq. (3), i.e. $$ \langle x|p|y \rangle = -i \delta'(x-y)  + \alpha \delta(x-y), $$ and $[x,p] = i$ is still satisfied. We can also add $$ \frac{\beta}{\sqrt{|x-y|}}\delta(x-y)$$ on the RHS of Eq. (3).  Here $\alpha$ and $\beta$ are two real numbers.  My question is, what is the most general expression of $\langle x|p|y \rangle$? Can we always absorb the additional term into a phase factor like Dirac's quantum mechanics book did?  Thank you very much in advance. What is virtual memory? I was double checking my notes for 'Virtual Memory' and the definition in my text book is:     Process of allocating a section of secondary storage to act as part of the main memory   Where as  says:     Virtual memory is a computer system technique which gives an application program the impression that it has contiguous working memory (an address space)   and (Wikipedia also says)     Note that "virtual memory" is more than just "using disk space to extend physical memory size"   Can anyone offer any clarification as to which is correct? If directory is empty do this, If directory is not empty do that bordermatrix with blocks I need to write a complicated matrix, that has a structure as in the attached picture. $A^TA+I$ is always invertible? I have few methods that returns different Generic Lists.   Exists in .net any class static method or whatever to convert any list into a datatable? The only thing that i can imagine is use Reflection to do this.  IF i have this:  List&lt;Whatever&gt; whatever = new List&lt;Whatever&gt;();   (This next code doesn't work of course, but i would like to have the possibility of:  DataTable dt = (DataTable) whatever; What's the maximum hand luggage volume you can take with you to match all (or important) airline regulations considering only international connections?  In case my question is not clear, I'm looking for the one biggest carry-on bag that is accepted by all (or important) airlines on international connections. Accepted dimensions tend to be somewhat different on different airlines, meaning that a specific bag might be allowed on one airline, but not on another.  So, my question is what is the biggest bag that meets all (or important) airline requirements? Is there any way to use a nether portal to travel to y = 250? How to update the PATH user environment variable from command-line How can I show that $y'=\sqrt{|y|}$ has infinitely many solutions? Show that the first order differential equation $y'(x)=\sqrt{|y(x)|}$ with intial value $y(1/2)= 1/16$ has infinitely many solutions on the interval [−1, 1].  My thought were to show that this equation has two solutions (just by ansatz, or just looking at the interval $]0, 1]$ to get $y'(x) = \sqrt{|y(x)|}$) and deduce from that that there must be infinitely many solutions since the solution set forms a vector space. I've got a nagging feeling this isn't the way to go though. Can anybody give me a hint where to look? How to split numbers into columns with negative and positive values, without empty cells? A normal divided by the $\sqrt{\chi^2(s)/s}$ gives you a t-distribution -- proof let $Z \sim N(0,1)$ and $W \sim \chi^2(s)$.  If $Z$ and $W$ are independently distributed then the variable $Y = \frac{Z}{\sqrt{W/s}}$ follows a $t$ distribution with degrees of freedom $s$.  I am looking for a proof of this fact, a reference is good enough if you do not want to write down the complete argument.
