How do I deal with a compromised server?
How can I find the program I'm hiding in bash Do magic item spells require concentration? Do magic items that cast a magic effect such as a ring of invisibility require the user to maintain concentration as if they had cast the spell?  Is this also the case if the item casting the spell is an artifact?   If the item is intelligent can it concentrate on the spell? Home button broken and Notification Center stuck my home button on my ipod touch 5th Gen has been broken for  while so I have been using assistive touch. Earlier on my notification centre got stuck half way down the lock screen, making my ipod completely unusable.   I tried turning it off but the notification centre is blocking the slider and obviously I can't restart it since my home button is broken. Has anyone got any solutions? It's an absolute nightmare! Plotting logarithmic regression with gnuplot using PGFPlots I have the data in 001.csv below that I want to plot. I need two plots: one showing the data and another one showing logarithmic regression. I have no problems plotting the line for the data (and also adding a linear regression line) but I just can't manage to get a logarithmic regression line in there. As far as I understand, I need to use gnuplot for this but unfortunately I can't make it work. Any help would be much much appreciated.

Can "who" as a relative pronoun sometimes be omitted? Can not start Chrome via command line I have a script that needs to run on multiple machines. The problem is, if I open a command line and type in chrome or chrome.exe, I get the same error message that it is not recognized as an internal or external command... I have already added it to my paths (as per screen shot below, see bottom entry in the paths) . It works this way on other computers.  The command prompt has been restarted (as has the computer) since updating the paths. Why does it not open Chrome as it does on my other machine(s)? Whilst entering C:\Program Files (x86)\Google\Chrome\Application\chrome.exe directly into the command line and pressing enter does make Chrome launch, I don't see why the path is not working. I am having a problem with Windows 7. When I boot up, the CPU jumps to 100% execution for about 10-15 minutes. During this time, it is really slow, and if I play any music, the songs play slowly and sound distorted.  I tried to scan my computer with different antivirus programs, I used Spybot, HijackThis, and CCleaner, but I didn’t find anything of note.  I watched the process list in Task Manager and saw that there are two processes that are to blame. There are two copies of svchost.exe, one using ~48% CPU, the second (under the Network Service account) using ~37%. For the first 15 minutes, the CPU runs at about 70-80%, then eventually drops to 30-40%.  I don’t know what to do. I could not find a way to stop the services, and if I try to kill them, sometimes the system crashes. Check for internet connection with Swift How to guess a curve distribution from count data I have a sample composed by 2500 count data values. I've plotted in R the corresponding histogram and ecdf. I've run the One-Sample Kolmogorov-Smirnov test to check if the distribution is either exponential or poisson, but I got negative results.  Is it possible that the One-Sample Kolmogorov-Smirnov test, it's not the correct test to work with this count data.  What is the best way to identify a distribution for this kind of data? Is -1 followed by a singular or plural noun? How to fill in the Schengen visa application form when going to several countries? I will be traveling to France, Italy and Germany with France being my main destination. So I am applying in the French consulate for Schengen visa. I will be traveling on my own and will be staying in hotels.  I had some doubts with regards to filling the application form for Schengen visa.    Q22- Member State(s) of destination: Should I fill in all three of my destinations ? Q31 Surname and first name of the inviting person(s) in the Member State(s). If not applicable, name of the hotel(s) or temporary accommodation(s) in the Member State(s) : This field has barely a line of space to enter. Should I just enter the hotel name in France (my main destination) ?  Q32 Surname and first name of the inviting person(s) in the Member State(s). If not applicable, name of the hotel(s) or temporary accommodation(s) in the Member State(s): Same problem as Q31. Very little space. Should I just enter address of the one hotel I entered in earlier Q ? Which is grammatically correct?  I can only do so much in this time.  or  I can do only so much in this time. The  tag doesn't appear to be very useful.  It's used in a variety of ways (for reading, writing, showing, transforming, compiling, translating, obfuscating, obtaining, ... source code) on 1747 questions right now, and doesn't appear to be adding any classification value to the site.  Can we get rid of it? What should I look for when buying chain lube / lubricant? In the past, I personally have only used WD-40.   However, I have occasionally had my bicycle looked over at the locally run, free service sessions and most of the mechanics there use a hand applied type of greasy gel (I forget the name).  Questions:   Is WD-40 suitable for bicycle chains? Would alternatives provide better chain longevity? When shopping around for lubricant, what are the most important things to look for? What do you use and why?  (optional added extra) Any tips for reducing chain wear? How do you return to the default view (the one you see when blender starts)? CMake & CTest : make test doesn't build tests Combining multirow and multicolumn When combining multirow and multicolumn in the same cell of a table I am getting extra vertical lines:  \documentclass[plain]{article} \usepackage{multirow} \pagestyle{empty}  \begin{document}  \begin{tabular}{|l|l|l|l|}\hline   \multirow{10}{*}{numeric literals} &amp; \multirow{5}{*}{integers} &amp; in decimal &amp; \verb|8743| \\ \cline{3-4}   &amp; &amp; \multirow{2}{*}{in octal} &amp; \verb|0o7464| \\ \cline{4-4}   &amp; &amp; &amp; \verb|0O103| \\ \cline{3-4}   &amp; &amp; \multirow{2}{*}{in hexadecimal} &amp; \verb|0x5A0FF| \\ \cline{4-4}   &amp; &amp; &amp; \verb|0xE0F2| \\ \cline{2-4}   &amp; \multirow{5}{*}{fractionals} &amp; \multirow{5}{*}{in decimal} &amp; \verb|140.58| \\ \cline{4-4}   &amp; &amp; &amp; \verb|8.04e7| \\ \cline{4-4}   &amp; &amp; &amp; \verb|0.347E+12| \\ \cline{4-4}   &amp; &amp; &amp; \verb|5.47E-12| \\ \cline{4-4}   &amp; &amp; &amp; \verb|47e22| \\ \cline{1-4}   \multicolumn{3}{|l|}{\multirow{3}{*}{char literals}} &amp; \verb|'H'| \\ \cline{4-4}   &amp; &amp; &amp; \verb|'\n'| \\ \cline{4-4}   &amp; &amp; &amp; \verb|'\x65'| \\ \cline{1-4}   \multicolumn{3}{|l|}{\multirow{2}{*}{string literals}} &amp; \verb|"bom dia"| \\ \cline{4-4}   &amp; &amp; &amp; \verb|"ouro preto\nmg"| \\ \cline{1-4} \end{tabular}  \end{document}     Notice the vertical lines in the char literals and string literals cells (which should span three columns). How can they be avoided? Should I assign dwellers to the storage room? I am trying to find the correct opposite of a delegate in the context of a person being a representative of someone else that have allowed or chosen them to be their delegate. What would you call that "someone else?" The only word I could find is a delegator (which isn't a real word in English) or assigner, but they are technical words rather than descriptive.    Any other word I could use?    Think of it in a sentence like this:       Here is a list of all the delegates in the company.   But that is the list of their _ _ _ _ _ (what can go here?).   I am trying to avoid fillers such as:  bosses, agents, managers, etc.
