I've been enjoying the new features and stability of blender 2.83.5, however I discovered an issue. Normally when you create a new object in your scene a menu appears to offer options on the object. I am getting this menu however it is entirely grayed out and uneditable. If anyone knows something about the new version having either a bug or new way of working I'd be very appreciative of any info.
Sometimes when adding an object to the scene I see that all options (on toolbar or in window after pressing F6) are disabled. Can anyone tell me when can this happen? What is causing it and how to revert it - make it enabled again. It worked for me when I restarted Blender and reloaded the scene. However I would really like to know what can cause it?
How to prevent click events on the document body (maybe a bug in Cordova?) Let $(e_n)$ (where $ e_n $ has a 1 in the $n$-th place and zeros otherwise) be unit  standard vectors of $\ell_\infty$.   Why is $(e_n)$ not a basis for $\ell_\infty$?  Thanks. the dinner vs. dinner (grammar question) From the sitcom  (episode ):     KRAMER: (scanning a menu) So, how was the dinner last night?   JERRY: Oh, well…   KRAMER: Did you enjoy the duck? (Elaine comes over…) Oh, Elaine! I was just   asking how dinner went last night.   ELAINE: (sitting down) Oh, well…   KRAMER: Alright, what did you do to Poppie?   ELAINE: Nothing.   KRAMER: Well, he's in the hospital. And the cook says you put him there.   ELAINE: What's wrong with him?   KRAMER: I don't know. I'm gonna go and visit him later. It would be nice if   you got him something. (Punches the table to accentuate this and leaves.)   JERRY: We should get him something.   ELAINE: Yeah. You're right.   I don't understand why Kramer first says the dinner, but when he says it a second time, he drops the article. What's the reason behind that? I want to make a schematic of this board. Can anyone tell me how? This is the views section of the site analytics visible to 25k users on one of my sites:    That's, uh, not correct.  Our site has had its usual activity level during this time.  I checked a couple other sites, and the pattern is consistent.  This looks like a problem in the analytics data that's coming in; did Google change their API?  Update: Same site a week later; note that in addition to the brief spike of accuracy, page views have dropped to (near-)zero for the whole period, unlike the earlier report.  (I know this question has been closed as a dupe, but I thought having the two screen shots together might help somebody.) how to calculate $\int_C \frac{2xy^2dx-2yx^2dy}{x^2+y^2}$ using green theorm or directly Calculate $$\int_C \frac{2xy^2dx-2yx^2dy}{x^2+y^2},$$ where $C$ is the ellipse $3x^2 +5y^2 = 1$ taken in the positive direction.   I tried to calculate the integral using green theorm.  now i need to build enclosier that doesn't enclose $(0,0)$ i am having hard time guessing what to build.  a circle and ellipse might be perfect but then the domain is not easy to write. can i have hint please ?

I know that python has a len() function that is used to determine the size of a string, but I was wondering why it's not a method of the string object.  Update  Ok, I realized I was embarrassingly mistaken. __len__() is actually a method of a string object. It just seems weird to see object oriented code in Python using the len function on string objects. Furthermore, it's also weird to see __len__ as the name instead of just len. If $I$ is a non-zero proper ideal of a commutative integral domain, is it possible for $I$ to be its own square? Knitr: opts_chunk$set() not working in Rscript command Is a semigroup with unique right identity and left inverse a group? We know that a semigroup with a right identity and right inverse for all elements is a group (e.g. see ). Symmetrically, also a left identity together with a left inverse implies a group. We also know that a semigroup with a right identity and a left inverse is NOT necessarily a group (see ). My questions are:   in a semigroup, is the existence of a UNIQUE right identity together with the existence of a left inverse enough to have a group? in a semigroup, is the existence of a right identity together with the existence of a UNIQUE left inverse enough to have a group?   I think both these claims are false,  ut haven't found a counter-example so far. Windows 7, file properties, date modified, how do you show seconds? Anyone know a way to immediately show the seconds of a file's date modified property in the GUI? So if you create a file, any file in any directory, right-click and choose Properties, the date modified (if it's recent) will say something like "dd/mm/yyy hh:mm, one minute ago" - reminder this is in Windows 7. Windows XP did it normally. Then they changed something.  If you wait a while, eventually you'll see the seconds, I'm not sure how long a while is, but this is incredibly annoying if you want to troubleshoot something that relies on the seconds of timestamps... is there a setting? registry key I can change perhaps?  I'm literally using Chrome, pasting in the path of the directory to be able to see the seconds quickly (as a workaround) but would be nice to be able to use Win7. A while ago I upgraded from Ubuntu 17.04 to Ubuntu 17.10 and everything is working fine except for the fact that the icon in the window title bar of my Terminal seems to be stretched out to some ridiculous size.    This only seems to happen in the Terminal window. The Nautilus icon is completely fine.    The problem seems to go away if I login into an Xorg session instead of a Wayland one. I've looked around and didn't find any immediate solution to this. Any help would be greatly appreciated. Let $\Gamma$ denote the positively oriented circle of radius $2$ with center at the origin. Let $f$ be an analytic function on $\{z \in\mathbb{C} : |z|&gt;1 \}$, and let $$\lim_{z\to \infty}f(z)=0.$$  Prove that $$ f(z)=\frac{1}{2\pi i} \int_{\Gamma} \frac{f(\xi)}{z-\xi}d\xi,  $$ for all $z\in\mathbb{C}$ with $|z|&gt;2$.  I have no idea how to even start. Any hint will be appreciated. Using ExactTarget DEManager to update record? Is there a way to use ExactTarget DEManager to update a data extension record instead of only add? I have a data extension that adds subscribers to specified lists (each list is its own boolean column). If a user goes to my DEManager form and the subscriber already exists, the form will return the error url ("subscriber already exists" or something similar). Is there any way instead for the form to update the existing subscriber record instead of it returning an error? If so, is there a way to use DEManager to first check if a record exists, and if it doesn't then add, otherwise update?

The Intel DZ68DB motherboard with an Intel I7 2600 CPU. Is it possible to install Ubuntu on my Windows 8 computer without any CD or USB drive? Please read entire post CAREFULLY before answering.

WUBI does not support UEFI, and This computer uses it. No Virtual PC programs like VirtualBox or VMWare, because it takes memory.   EDIT : I already found a USB drive in my home, so now it is installed on my computer xD One confusion over conditional expectation Suppose for two random variables $X_1$ and $X_2$ $\sigma(X_1) = \sigma(X_2)$. Why $E[Y | X_1] = E[Y | X_2]$ a.e. ?  the set where $X_1= X_1(\omega)$ can be different from the set $X_2= X_2(\omega) $. How can then conditional expectation conditioned on the event can be equal ?
