Who knocks at the door?  Who does knock at the door?    I am confused here. Usually, first sentence is acceptable. But I did not read about the 2nd one. Is it correct? Is it an emphatic sentence of present indefinite tense?

Sorry, I'm still a newbie to blender, but why are some edges visible only in edit mode, but not in wireframe view? is it a bug or am I missing something here?  edit mode: Edges visible. Object mode, wireframe view: Pooff, they're gone. what can i do to fix this? / thanks Why is $H(k\mathbin\Vert x)$ not a secure MAC construction? What’s (not) spam? Somebody asked the following :    Clearly this is just a troll post so I (and other users) flagged it as spam. The spam flag was subsequently disputed (which I think simply means that a moderator rejected it):    Huh? Puzzled, I took another look at the list of possible flagging reasons:     I am flagging this question because         it is spam   This question is effectively an advertisement with no disclosure. It is not useful or relevant, but promotional.   it is offensive, abusive, or hate speech   This question contains content that a reasonable person would deem inappropriate for   respectful discourse.   it is a duplicate...   This question has been asked before and already has an answer.   it should be closed for another reason...   This question does not meet this site's standards and should be closed.   it is very low quality   This question has severe formatting or content problems. This question is unlikely to be salvageable through editing, and might need to be removed.   other (needs ♦ moderator attention)   This question needs a moderator's attention. Please describe exactly what's wrong.      Of these, only a few are applicable at all: “spam”, “should be closed for another reason”, “low quality” and “requires moderator attention”.  But:   it shouldn’t be closed (it has no value – it should be deleted), it’s not “low quality” (the description seems to fit actual, albeit bad, questions), and it doesn’t require moderator attention (I certainly didn’t want to bother a mod with this worthless post).   So I still think “spam” is the most fitting reason. Maybe it would help to have a more apt reason “troll post”, or maybe we could explicitly subsume this under one of the other points? How do I go about evaluating the following by contour integration?  $$ \int^1_0 \frac{dx}{(x^{2} - x^{3})^{1/3}} $$  The question does not fit in the standard form of : $\int^{2\pi}_0$ or $\int^\infty_{-\infty}$  etc.  I tried substituting $ x = cos(\theta) $ but got stuck. Login not redirecting back to page where login link was clicked if account created Stealing and reattaching a running process It's sunday and I left an instance of R running in the office. The script finished running, and I would like to save my workspace without going to the office. I can ssh to the computer, but I have not run the program into screen.  Is there a way, over ssh, to disown the process (I don't have access to jobsid of the terminal the program is running on!) and reattach it with say, reptyr?

I often see tutorials online that connect various commands with different symbols. For example:  command1 |  command2 command1 &amp;  command2 command1 || command2     command1 &amp;&amp; command2   Others seem to be connecting commands to files:  command1  &gt; file1 command1  &gt;&gt; file1   What are these things?

Installing particular versions when repo has newer versions? Can I use variables inside {} expansion without `eval`? Can I use variables inside {} expansion without appealing to eval? If so, how?

I am trying to put a label over the transparent plastic bottle, but i was unable to do so, because when i build the bottle material(plastic) and mix it with the diffuse shader(using the label texture), the label gets faded. So the solution i found was to duplicate the bottle and scale a little bit and apply the label material on it. So it looks its the same material, but in reality its one material over the other. How can I make my plastic material be under my label material(image)? Here's how it looks:   Here's my material setting for the plastic bottle:   Thanks in advance. My interest in Blender comes from wanting to use it to model physical structures and produce architectural drawings; what I have so far is really impressive, but there doesn't seem to be too much information about my particular interest.   Are there any (Blender-) resources that would be particularly useful for architects? E.g. packages of standard 'elements' like windows, doors, roofs or whatever, or perhaps a discussion group specifically for architects? I want a green for "correct answer" and a red for "wrong answer". My current choice is rgb(144, 238, 144) for the green and rgb(250, 128, 114) for the red. (See wikilearner.net/wiki for the colours in action.)  I have been told that these colors are very close in contrast, making it difficult for a person with red-green color-blindness. What would be a better choice? Does 'but for' mean:  'If we had X (but we didn't), Y would have been the consequence'?  Or can it also mean; because we had X, as a result Y happened?   Some different examples of but for:  (Case 1)     But for a cup coffee, it was to be a productive day of writing.   Unfortunately, I'd run out, and spent the day craving.    (Case 2)     But for the glass of wine I had dinner, the house work didn't get   done.   (Case 3)     But for the glass of wine I had for dinner, I would have got the   house work done   What is the correct usage of "but for"?

Do I have to peel red potatoes before baking them? I recently made some potato wedges in the oven. I shared this recipe with my relative, who admonished me for not properly peeling the red potatoes before baking them.  She claims that there are disease and viruses that lie on the skin, so peeling it will get rid of it.  I bake it, so I assume that even the high heat in the oven would kill bacteria and germs. And besides that, I make sure to wash potatoes thoroughly before cooking them.  Am I in the wrong here? Should I have properly peeled the potato wedges before baking them? Personally I feel they add more flavor, and from all the pictures on the recipes online, it seems they also do not peel it. pfsense more than 2 isp provider is it possible to bridge more than 2 isp provider using pfsense? what router or device can bridge 2 or more isp providers in a router? i am planning to bridge at lease 5 isp providers to create a very good internet connection, what can i do to link all 5 providers in 1 router?
