How do I fix a "Problem with MergeList" or "status file could not be parsed" error when trying to do an update?
Say I have a cologne bottle of 100 ml that I want to carry in my hand luggage on a plane trip.  100 ml is the limit so it should be fine for the transport regulations (if not, please let me know!).  The problem I always encounter is regarding the storage of the bottle: how to prevent it from leaking?  What I normally do is to put it in a plastic bag, so that the possible loss remains there. It is fine, only that the bottle ends up quite wet.  What would be a better approach? I would like to compare the contents of a couple of collections in my Equals method.  I have a Dictionary and an IList.  Is there a built-in method to do this?  Edited: I want to compare two Dictionaries and two ILists, so I think what equality means is clear - if the two dictionaries contain the same keys mapped to the same values, then they're equal. Solve $\frac{d}{dx}f(x)=f(x-1)$ I am trying to find a function such that   $\dfrac{d}{dx}f(x)=f(x-1)$   Is there such function other than $0$ ? How to remove the handles from this faucet My bathroom faucet is leaking around the base of my right handle.  With previous faucets I've been able to use a set screw to loosen the handle and replace the washer.  With these, though, I can't seem to pop off the faucet handle.  Does anyone know how to remove this handle?  Does anyone know the brand of this faucet?  Update -- Nov 29th  I've already tried to get those cap ends off.  I tried to use some pliers and unscrew them, but couldn't remove it.  I tried taking a small flat head and popping off the ends.  Still nothing.  It doesn't seem like the come off.  I also tried unscrewing the handles, but they just don't see to turn for me.  Also there is definitely no set screw on the handles.  I've searched all around the faucet and found nothing indicating a set screw. Which partition is mounted to where? Map display not filling window in QGIS on Mac? In this screenshot of QGIS, you can see that the map is not filling the window. I have tried resizing the window in various ways.   Am I missing something obvious, or is this a bug?

I mean:  1) \bibitem{[8]} {\url{http://projects.webappsec.org/w/page/13246989/Web20Application20Security20Statistics\#Tableofcontent}}  2) \bibitem{[5]} Justin~Clarke ``SQL Injection Attacks and Defense'', Syngress Publishing, Inc.2009   Unfortunately font 1) is different from 2).  What should I do in oder to get the same font for both items?

I need an answer that does not include 'install X' or 'use sidecar container'. I am looking for something that relies on nothing more than bash and the basic shell commands. sort but keep header line at the top I am getting output from a program that first produces one line that is a bunch of column headers, and then a bunch of lines of data. I want to cut various columns of this output and view it sorted according to various columns. Without the headers, the cutting and sorting is easily accomplished via the -k option to sort along with cut or awk to view a subset of the columns. However, this method of sorting mixes the column headers in with the rest of the lines of output. Is there an easy way to keep the headers at the top? How to compile bibtex with TeXstudio? I am trying to use bibtex for the first time. I am on windows 7, using TeXstudio. I am trying to follow the steps of .  I have created a .bib file, put it in the right directory and written the code in my .tex file. However, I do not know how to compile bibtex with TeXstudio (I looked around in the menus but didn't find it).   Most tutorials I found don't explain how to do it, or say to run a command, which I'm not sure how to do.  Any help much appreciated! Program to balance speaker output for surround sound 2.1? When I upload an image to Stack Overflow, I cannot see my JPEG file in my post. It's all blank. I've tried it with different files, but gotten the same result. How do I convert or upgrade roads? I'm trying to optimize my road system a bit, mostly converting regular small roads into one-way roads. But the only way I can see to do that is to remove the old road entirely and build a new one. I can't seem to just build over the old one.   I can understand that limitation in cases where the new road type is larger, but it should be possible to upgrade to roads with the same size without tearing down the old road manually.   Is there an easier way to convert or upgrade roads, or do I have to manually remove the existing road every time? How to enable linking floating point library in TurboC? Moving users folder on Windows Vista/7 to another partition When I format the computer and reinstall Windows, my first step is move the My Documents folder to another partition. In Windows XP it wasn't enough because the desktop folder and another user folders was in the primary partition.  Now in Windows Vista and 7 we can use junctions/symlinks to "move" the folder to another partition and Windows and another programs will think that the data is in the primary partition.  What the fastest and secure steps to move the Users folder to another partition and to create the hardlinks correctly? How do I allow long URLs to have line breaks at any point. This is in the bibliography not the main text. I am trying to save space so don't want extra spaces to be added to make it only break at slashes, for example, as it does by default.  I am using biblatex+biber. Integral Representation of the Zeta Function: $\zeta(s)=\frac1{\Gamma(s)}\int_{0}^\infty \frac{x^{s-1}}{e^x-1}dx$ How does one get from this $$\zeta(s)=\sum_{k=1}^{\infty}\frac1{k^s}$$ to the integral representation $$\zeta(s)=\frac1{\Gamma(s)}\int_{0}^\infty \frac{x^{s-1}}{e^x-1}dx$$ of the Riemann Zeta function?  I can see that it can be rewritten as  $$\Gamma(s)\zeta(s)=\int_{0}^\infty \frac{x^{s-1}}{e^x-1}dx$$ and the Gamma function as an integral yields  $$\zeta(s)\int_{0}^\infty \frac{x^{s-1}}{e^x}dx=\int_{0}^\infty \frac{x^{s-1}}{e^x-1}dx$$  But this approach does not work as the right integral does not converge.  So how does one go from the summation to the integral representation?

If I try to manually delete it in Windows Explorer it does not let me, a permissions issue.
