What is difference between &quot;made in&quot; and &quot;made at&quot;? The example sentences are:   This thing was made in a factory.  This thing was made at a factory.    Are they both correct? Do they mean the same thing?
I usually use "at a company" but I have encountered some articles using "in a company", "in XYZ firm" or "in an organization".  Which one is right?
How to delay or slowly loop commands? I found 11 questions like this on gamingSE already, but none of them have proper and up-to-date answers. So I'm creating this Q&amp;A:  How do you either activate a command x seconds/minutes/hours/… in the future or every x seconds/minutes/… in a loop?  Repeating command blocks and ticking functions execute 20 times per second, redstone is  in many situations and most of the extremely fancy solutions, like falling blocks in cobwebs, have broken over time or are needlessly complicated. Old phone cannot connect to computer, the "computer connection" icon appears on phone I would like to get some pictures and audio out of an AT&amp;T SGH-a687 phone onto my Mac computer. I first tried connecting it to a New PC Studio on a PC, but there was a problem after transfer 2 photos, so I tried again. But the PC could no longer detect the phone, even though the "connected to computer" icon appears on the phone. I tried a different cable, different USB ports. No use.  So I downloaded the Samsung Kies on my Mac. Same thing, it tries to search for the phone once I connect the phone, but the computer doesn't detect anything. The phone still shows the "connected to computer" icon.  There is also Bluetooth (no internet on the phone) on the phone, but it failed to send the picture each time I tried.  What can I do at this point? Please also suggest data extraction software for either Mac or PC, if that's the easier route. Changing timezone in PHP Alright, quick question.  A server is running in Eastern Time. PHP program needs to make date calculations using Central time.  At the moment, I am putting this line at the very top of my script:  putenv("TZ=US/Central");   Is that the best way to go about that or is there some PHP trick I'm not aware of?  Cheers. Frobenius Inequality Rank I was looking for an answer for this problem in terms of matrices, but I really don't know how to prove this result. The proposition says that:  Let $A\in M_{m\times k}(\mathbb{C})$, $B\in M_{k\times p}(\mathbb{C})$ and $C\in M_{p\times n}(\mathbb{C})$, then $\textrm{rank}(AB)+\textrm{rank}(BC)\leq \textrm{rank}(B)+\textrm{rank}(ABC)$ Where can I get the original Unix? Finding solutions to congruence equations Consider the function : $$f: \mathbb{R}^2 \rightarrow \mathbb{R} , (x,y) \mapsto   \begin{cases}         0 &amp; \text{for } (x,y)=(0,0) \\    \frac{x^3}{x^2+y^2}       &amp; \text{for } (x,y) \neq (0,0)   \end{cases} $$  Show that $f$ not differentiable at $(0,0)$ but all directional derivatives exist.  I don't know how to tackle this problem. Can someone give some hints or solve the problem? Thanks :) how to hide mesh but keep hair particles Consider this conversation:      John: I am giving free chess lessons.   Mary: Nice! You’re a true teacher.   John: How so?   Mary: A true teacher imparts knowledge without a price tag.   John: But what if teaching is his only source of income? Would he not be a “true” teacher then?   Mark (in response to the question above): You clearly mentioned “free chess lesson”.   I don’t see how Mark’s comment adds anything to the discussion or makes sense in the current discussion. It is “redundant” — that’s one word for it — but is there a more fitting word? Sometimes I need to write text and then pipe that text into another command. My usual workflow goes something like this:   vim # I edit and save my file as file.txt cat file.txt | pandoc -o file.pdf # pandoc is an example  rm file.txt   I find this cumbersome and seeking to learn bash scripting I'd like to make the process much simpler by writing a command which fires open an editor and when the editor closes pipe the output of the editor to stdout.  Then I'd be able to run the command as quickedit | pandoc -o file.pdf.   I'm not sure how this would work. I already wrote a function to automate this by following the exact workflow above plus some additions. It generates a random string to act as a filename and passes that to vim when the function is invoked. When the user exits vim by saving the file, the function prints the file to the console and then deletes the file.   function quickedit {     filename="$(cat /dev/urandom | env LC_CTYPE=C tr -cd 'a-f0-9' | head -c 32)"     vim $filename     cat $filename     rm $filename } # The problem: # =&gt; Vim: Warning: Output is not to a terminal   The problem I soon encountered is that when I do something like quickedit | command vim itself can't be used as an editor because all output is constrained to the pipe.   I'm wondering if there are any workarounds to this, so that I could pipe the output of my quickedit function. The suboptimal alternative is to fire up a separate editor, say sublime text, but I really want to stay in the terminal. How to escape ampersand in \acro command? I am trying to use the acronym package to create an acronym list. The problem is that one of the acronyms I need to use contains an ampersand ('&amp;').  But when I try to compile the .tex file I get this error:  ! Missing \endcsname inserted. &lt;to be read again&gt;                     \&amp; l.2 ...&amp;M}[\AC@hyperlink{M\&amp;M}{M\&amp;M}]{I like them}   Here is an example:  \usepackage{amsmath} \usepackage{acronym}  \begin{document}  \begin{acronym} \acro{M\&amp;M}{I like them} \end{acronym}  \end{document}   So how do I use an ampersand in an acronym using the acronym package?  More generally, how is it possible to apply special formatting to a single acronym? For example  \acro{\textit{IAF}}{Italic acronym frenzy} Compact vs Mirrorless - why pick one over another? What would be a reason for one to pick the compact (whatever it'd be P&amp;S or something more advanced) over mirrorless compact system camera  ?  Right now market is quite confusing — we have huge market of tiny-sensor compacts, we have mirrorless that use sensors in a size of these from P&amp;S cameras (Nikon 1 being notable example), we have compacts with sensors bigger than most popular mirrorless system (Canon G1X vs m4/3), we have lot of APS-C sensor mirrorless which are matched by some of the compacts (Fuji X100 being most notable example, but even Leica has its X2),  and to make it even more confusing — Sony released RX1 with full frame sensor, beating crap out of every mirrorless on a market.  So what are your arguments to pick compact over a mirrorless?  Why are they better, what's the reason behind logic of companies like Fujifilm which at the same time offers P&amp;S and X-mount mirrorless using same sensor size? 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?

Opinions apart, I am having problems when running sudo dpkg --configure -a  My computer stops processing the command here:  You may know Adobe Flash Player is no longer supported, and I believe that could be why the command is unable to load pepperflashplugin-nonfree. I have tried fixing the problem by checking older posts here, but none of them was able to fix this problem. bash function cannot change the value of a local variable when called by $() The following code works differently depending on which way Parse_Short_Switches() is called.  After calling the function 'Parse_Short_Switches' by using result=$(Parse_Short_Switches), the value of $error_flag is NOT set to -1 as I would expect.  After calling the function 'Parse_Short_Switches' by simply using Parse_Short_Switches, the the value of $error_flag is set to -1 as I would expect.  Any help would be greatly appreciated.

What is the minimum value of $(1 + a_1)(1 + a_2). . .(1 + a_n)$? Suppose $a_1, a_2,\dots , a_n$ are $n$ positive real numbers with $a_1a_2 \dots a_n = 1$.   Then what is the minimum value of $(1 + a_1)(1 + a_2). . .(1 + a_n)$ ?    I think $(1 + a_1)(1 + a_2). . .(1 + a_n)$ takes its minimum value when $a_1=a_2=\dots=a_n=1$ and thus the minimum value is $2^n$.  I don't know how to prove it. Please help.
