i have Dell vostro laptop , and my keyboard is no more responding after i drop a cup of coffee over it. i am thinking of buying a new keyboard and attach it. but i have the following questions:-   will the new keyboard work well automatically without having to configure it ? in case the keyboard need some configuration , will i be able to install it without having to type anything , while installting the new keyboard , Or i should have external keyboard while installing the new keyboard? last question, after i drop the cofee over the keyboard , i have remove it and i clean it using pure water ? could this have harmed the keyboard ?
I have just dropped a half full latté on my company laptop and am not sure what to do.  Is there a way I can make sure that my laptop is usable again?  What steps must I go through to improve it's chances of survival?
How should one maintain and update a MiKTeX installation? Why don't Death Eaters always use Avada Kedavra?

How can I make a script (or make some changes) to allow me to turn the screen off in Ubuntu (12.04) whenever I want, the way thevscreen can be turned off in Cellphones?  And how can I make a combination of keys (a shortcut) to execute that script?  I want to conserve power.  I've seen this question    but there is no hotkey for it.  Moreover, in the answer, it is said that there are many ways to accomplish this so I'd like to know more. What's the intuition behind the identities $\cos(z)= \cosh(iz)$ and $\sin(z)=-i\sinh(iz)$? I'm trying to understand in an intuitive manner the relationship between the circular and hyperbolic functions in the complex plane, i.e.:  $$\cos(z)= \cosh(iz)$$ $$\sin(z)=-i\sinh(iz)$$  where $z$ is a complex number.  From a geometric point of view, what I understand is that cos is the composition of a rotation through $\frac{\pi}{2}$, followed by cosh, and sin is the composition of a rotation through $\frac{\pi}{2}$, followed by sinh, followed by a rotation through $-\frac{\pi}{2}$ (where sin, cos, sinh, cosh are defined as complex functions).  Where does this connection come from? Is there some way it can be visualized in terms of complex mappings? (I'm not asking for a proof of the identities, I already know one). Nexus 7 is stuck in reboot loop after full discharge I have a few day old Nexus 7 tablet, unrooted, bootloader still locked, and otherwise in factory condition. This morning, it ran its charge out. When I plugged in it, this happens:   Google Logo appears. Nexus Logo appears. Lock screen which shows charging: 0%. White screen, device powers off. Repeat.   What is happening? Thanks! How to execute code after html form reset with jquery? I have a Godox X2Tc and a Godox X1Rc. I want to control my Canon Speedlite 430 EXII. (I also have a Godox V1, which is a beautiful thing!) I have the Canon Speedlite attached to the Godox receiver, so it should fire. It just wont! How do I set it up correctly so the receiver makes the Canon Speedlite fire?  Update: Michael C answered this question. I had the ID numbers set differently on the transmitter and receiver. I made them the same and now it all works. Perfect! Thanks Michael!! There is a formal definition for the Big O notation in . Up to now I have come across Big O in Numerical Analysis, Calculus and Algorithms which all are pretty distinct fields. What I am wondering is if that definition is global and is the only one that is used in every field where the Big O is involved or there are other ways that the Big O is defined in other areas  of Mathematics. I am looking for the title of a novel that I only caught part of on audio. It takes place within our current time frame and deals with the Moon getting struck and fragmented into (initially) 7 pieces by a high-speed asteroid that they called "The Agent".  Within a few weeks of this episode, scientists figure out the the Moon will continue to break down in a cascade reaction over the next couple of years until the planet gets bombarded by so much debris that it sterilizes Earth. The governments of the world frantically start to build a series of ships using swarming concepts to evacuate the planet as much as possible... and that's all I have heard so far.  Thanks for any info. Remount drive without physically disconnecting? So I have unmounted a usb external hard drive but I went to re-mount it.  Is there a command that I can use to remount the drive?  Only way I know to re-mount a drive is to disconnect the usb cable from my Mac and reconnect it. Build a basic Python iterator How would one create an iterative function (or iterator object) in python? Where was Alastor Moody during Harry Potter and the Half Blood Prince? Can't boot without Flash Drive plugged in I have this file:  sometext1{ string1 }  sometext2{ string2 string3 }  sometext3{ string4 string5 string6 }   I want to search this file for a specific string and print everything before this string up to the opening { and everything after this string up to the closing }. I tried to achieve this with sed but if I try to print everything in the range /{/,/string2/ for example sed prints this:  sometext1{ string1 }  sometext2{ string2 sometext3{ string4 string5 string6 }   If I search for the string "string2" I need the output to be:   sometext2{ string2 string3 }   Thanks. Differences between no child vs no children a) They have no child. b) They have no children.  Are both a) and b) correct? Though b) seems more common. Is the simulation hypothesis outside of science? On the question of the  (i.e. that reality is a simulation), a friend of mine once remarked he didn't accept it on the grounds of . To me (with my admittedly instrumentalist view of science) this seems a misuse of Ockham's razor in that all my friend is really claiming is that it isn't empirically necessary (and hence outside of science).  Is the simulation hypothesis outside of science? If so, then does it pose a problem for scientific realism? If not, is it falsifiable? Is it an empirical question? Saving an Adobe illustrator file as a pdf - are fonts embedded? If so, why does Adobe illustrator say I don't have the font when I open it? If I have an Adobe Illustrator file, and I save it as a .pdf - it looks like the fonts are included in that .pdf file. (I think this because when I open the .pdf file in Reader it looks the way I expect it to.) However, when I open this same .pdf file on a different computer (or workstation) with Adobe Illustrator - Illustrator says I 'don't have the font I need'. This doesn't make sense to me because - If I can see the document correctly in reader, I would expect it to be there for Illustrator as well. Can someone explain why this is? I am asking because saving a file as a .pdf for print seems to handle most font troubles that come up - but sometimes I need to change the text in a file before I print it... I am hoping there is a way to open a .pdf so that .ai recognizes that the font is in there.  But I am unsure on the details of saving as a .pdf in Illustrator, how fonts are handled, and what is possible. I can't seem to work out the inequality $(\sum |x_n|^q)^{1/q} \leq (\sum |x_n|^p)^{1/p}$ for $p \leq q$ (which I'm assuming is the way to go about it). Biblatex: URL-breaking not working in DVI-mode I'm preparing my bibliography and noticed that biblatex-printbibliography produces Overfull \hbox several times.  Examples (gray lines indicates text margins, red line is the physical page margin):        Why is hyperref line-breaking not working as expected using pdflatex or even latex -&gt; dvipdfm BUT not using latex -&gt; dvips -&gt; ps2pdf?  Also it would be great if someone could point out how I can raise the indentation of the second (and following) lines, as this might look better.  edit: Customized question, as the answer given by lockstep solved the third problem. The second problem seems to be identical to the first.  \documentclass[12pt]{scrbook} \usepackage[english]{babel} \usepackage[utf8]{inputenc} \usepackage[T1]{fontenc} \usepackage[ps2pdf]{hyperref} %\usepackage[ps2pdf,breaklinks=true]{hyperref} %This doesn't change anything. %\usepackage{breakurl} %That makes no difference either.  \usepackage[a4paper,twoside,showframe]{geometry} %show text margins  \usepackage[style=alphabetic,backend=biber,maxnames=4,minnames=3,maxbibnames=99]{biblatex} \bibliography{biblatex-issue}  \begin{document} \nocite{*}  \printbibliography[heading=subbibliography,type=article,prefixnumbers={A-}] \printbibliography[heading=subbibliography,type=book,prefixnumbers={B-}] \printbibliography[heading=subbibliography,type=online]  \end{document}   And the bib-file:  @online{GLS:datasheet,     title         = "GLS Datasheet",     organization  = "Optoelectronics Research Centre",     howpublished ="Website",     date = "2004-09",     urldate="2013-07-01",     url ="http://www.southampton.XXXX",     address       = "Southampton, United Kingdom" } @book {Lifante:Fundamentals,     title = "Integrated Photonics: Fundamentals",     author = "Lifante, Ginés",     publisher = "J.Wiley",     address = "Chichester",     year = "2003",     type = "text",     isbn = "9780470848685" } @article{Labadie:First_fringes,     author = {Labadie, L. and Mart\'{\i}n, G. and Anheier, N.
