At what speed am I walking?
Does walking fast prevent eggs hatching?
Can I make my Ubuntu make sounds when I press Caps Lock etc.? Allow folding/collapsing of certain segments of posts A question with attachments, screenshots and/or long code, makes it vertically long and often difficult to read fast.  It would be nice to have a new kind of format, such as 'hideable', with a graphic button or a '+' / '-' sign, so you can add additional details, visible only on a click. How to show $a,b$ coprime to $n\Rightarrow ab$ coprime to $n$? need to move a domain controller, the first in the forest that holds all the fsmo roles, to another location in a clients building. it will require turning off this dc, call it dc1 for this question. i want to transfer the fsmo roles to a new domain controller call the new one dc2. dc2 is already on the network and has been promoted and made a domain controller, it's dns settings are set and it is also a global catalog (GC). the work is scheduled to be done after hours and i am also planning on moving the dhcp server to dc2.  i am looking for a best practices checklist of things to verify prior to moving fsmo roles and turning dc1 off? as far as i know there are no issues with replication between the dc's. my biggest worry is if i turn on dc1 after moving it and i have hardware issues or boot issues, i would rather move the fsmo roles to a known good one that is a few months old (dc2) vs still using a 5yr old box (dc1), this is part of my migration strategy too.   thanks for the help. Is Tactical Down-Voting ever valid? Has anyone noticed any tactical downvoting of their, or other people, answers?  For example, in a recent answer to a question, my answer described a possible solution.  Shortly afterwards, another answer appeared following the solution I had mentioned.    I know that this is completely in the spirit of the site, however my answer had been down voted even though it was still as valid as it ever was.  Another poster also had his equally valid solution down voted.  There is no way of knowing the reason behind the down voting, as no comments were left, but I am suspicious as to the ethics behind down voting someone else's valid answer in the hope of making their own answer more prominent.  Are people really that desperate to gain reputation?  I have seen comments in other posts that suggest that tactical downvoting has occurred.  So, does anyone think that it is acceptable to downvote another post, even though it is still correct but may not provide a complete answer, to make their own appear more favourably? Proof that $\suṃ̣_{k=1}^{n}k {n \choose k}$ for $n \in \mathbb N$ is equal to $n2^{n-1}$.  As a hint I got that $k {n \choose k} = n {n-1\choose k-1} $.  I tried solving this by induction but, in the inductive step I'm not arriving to the correct result. Cite in the caption of a graphic but not in \listoffigures? Sometimes I'd like to cite the reference in the caption of a graphic. But I want to avoid that this citation is displayed in the \listoffigures. How can I achieve that?  Fore example with this code:  \begin{figure}[htb] \centering \includegraphics{overview_pyramid.png} \caption{Overview pyramid \cite{LM2010}}\label{fg:overview_pyramid} \end{figure} Is there a way to see questions with a certain tag from all Stack Exchange sites? For example, I see there are questions with the  tag on Stack Overflow, but there are also such questions on Super User, Unix/Linux, and other sites in the network.  Is there a way to follow a tag across all of the Stack Exchange sites, so that one can see the global activity of a topic without visiting all the sites separately? Rootspaces are $\mathop{ad}$ nilpotent A financial planner treated us in a dismissive fashion and I want to say that he "gave us the back of his hand" but that phrase doesn't seem to have the meaning of dismissive. Does it or is there a similar idiom? Why are my Cycles settings missing? so I'm working on a little bathroom scene and wanted to make a clay render. I started looking for the material override which I kinda knew where it was and on the way I switched my render engine accidently to workbench instead of cycles. Switched to cycles all my seetings on the render tab are missing except color management and free style. Hows that? I restarted blender multiple times and tried some other stuff but nothing changed a thing, and I'd rather avoid a new installation How can I edit/create new launcher items in Unity by hand? Software was blocked from opening because it is not from an identified developer I went to run LibreOffice on my OS X 10.9 and it would not let me install it. It said it was from an unidentified developer. I'm aware of the security features of the Mac and went to System Preferences to allow the software to run.   When I opened this setting I saw a button that said, '"LibreOffice" was blocked from opening because it is not from an identified developer.' and there was a button next to it that said "Open Anyway". I clicked this button and nothing happened. I clicked it multiple times, like a hundred, out of frustration. Is there something else I need to do? Could someone verify this is not a bug?   UPDATE: I've included the photo below of what my System Preferences screen looked like and the button I pushed that didn't work.  UPDATE II: So I tried opening the application again and went into the system preferences and pressed the "Open Anyway" button again and nothing happened at first but a few minutes later while I was typing an email something flashed across my screen, possibly another dialog (or more likely a chewpacabra), but it quickly disappeared and the next thing I know LibreOffice launched!

I can create tabs using Ctrl + T, but I'm not sure how to switch between tabs, see what tabs I have open, etc.  How do I navigate between tabs when using the modern UI Internet Explorer?
