My code:  \documentclass[                titlepage,                abstract               ]{scrartcl}  \usepackage[texindy]{imakeidx} \usepackage{hyperref}  \makeindex[intoc]  \title{Test} \dedication{Test.}  \begin{document}    \maketitle   \begin{abstract}     Test.   \end{abstract}    \pagenumbering{Roman}   \tableofcontents   \newpage   \pagenumbering{arabic}    \section{Test}     Das Zweistrom-Turbinen-Luftstrahltriebwerk (ZTL)\index{ZTL}~\ldots    \newpage   \pagenumbering{Roman}   \setcounter{page}{2}   \printindex  \end{document}   The table of contents should start with big Roman one. The text part (in the MWE starts with the test section) should start with an arabic one. This works.  But if I click in the index on the link, then it jumps to the title page (physical page one). I don't know what I'm doing wrong, but if I comment out the lines, which have to do with the page numbering (twice \pagenumbering{Roman}, \pagenumbering{arabic} and \setcounter{page}{2}), than it have the expected behavior. At the same time the hyperlinks in the table of contents work every time.  Why is it so and how can I fix this?  Thank you for your help and effort in advance!
I'm here with weird stuff again.  How can i continue numbering while changing numbering style to Arabic from Roman? For example let's assume I have total of 7 pages and I want to number the first 3 of them as : i,ii,iii; then I change back to Arabic again and continue counting as 4,5,6,7.
Normal subgroup of a normal subgroup Let $F,G,H$ be groups such that $F\trianglelefteq G \trianglelefteq H$.  I am asked whether we necessarily have $F\trianglelefteq H$. I think the answer is no but I cannot find any counterexample with usual groups. Is there a simple case where this property is not true? Efficiency of a heat pump water heater during the winter In my understanding, heat pump water heaters pump energy from the room around the water tank into the water.  Clearly, this must be energy efficient in the summer time, especially if I am using AC anyway. The heat pump water heater may actually cool the house a bit.  However, in the winter time the savings are not so obvious. If I am using a heater to heat the home, including the water tank room, then I don't see how there can be any savings. Instead of generating heat using a coil in the water, I generate heat in another area of the house which gets pumped into the water. A joule is a joule and I need to get it from somewhere. It seems to me that if I am actively heating the house, and lets assume everything is electric, then a heat pump water heater cannot be more efficient than a traditional one.  Am I missing something in the winter case? Ship an application with a database If your application requires a database and it comes with built in data, what is the best way to ship that application? Should I:   Precreate the SQLite database and include it in the .apk? Include the SQL commands with the application and have it create the database and insert the data on first use?   The drawbacks I see are:   Possible SQLite version mismatches might cause problems and I currently don't know where the database should go and how to access it. It may take a really long time to create and populate the database on the device.   Any suggestions? Pointers to the documentation regarding any issues would be greatly appreciated. Will reseting my device to factory setting unroot and remove superuser? Can a Rogue (D&D 3.5) use sneak attack on both the first and second attack? I know this seems like a question you can simply Google but the answers vary and my clan is under the impression that I can only use it on my first attack (once per round) and not on my second attack.  From Googling, I've understood that as long as the monster / enemy is flat-footed, flanked or caught off-guard, I can apply sneak attack on both my first and second attack in a round.  Is this correct?  Is it normal if the clan simply decides that that gives me an unfair advantage in combat and gives me only one sneak attack per round?

How to force the evaluation of a lambda term in haskell to the strong normal form Is there an easy way to calculate the total cost of tolls for a trip within the United States? Negation in English I'm trying to figure out how to assign higher priority to one PPA over another PPA. I had a look on bunch of the answers on this forum but none of them solves my problem.  We have two PPA sources on some of our servers which we stick into separate files in /etc/apt/sources.list.d . Some of these repos provide same packages (in terms of names) but different versions and possibly different binaries. Is there a way how we can PRIORITISE one repo over another ?  I read apt_preferences tutorial but it could not be more obscure and didn't find the answers for my question. Here is the situation. WE have the following sources:  $ ls -l /etc/apt/sources.list.d  total 12 -rw-r--r-- 1 root root 66 Jan  2 16:50 nginx-source.list -rw-r--r-- 1 root root 84 Jan  2 16:49 ruby-ng-experimental-source.list   where nginx-source.list content is:  deb     http://ppa.launchpad.net/nginx/stable/ubuntu precise main   and ruby-ng-experimental-source.list content is:  deb     http://ppa.launchpad.net/brightbox/ruby-ng-experimental/ubuntu precise main   Both of these sources provide nginx-full package of different versions etc. When I list the priorities ruby-ng-experimental-source.list is on top of output hence nginx-full is installed from that repo:  $ apt-cache policy nginx-full                                  nginx-full:   Installed: 1:1.2.3-1~38~precise1   Candidate: 1:1.2.6-1~43~precise1   Version table:      1:1.2.6-1~43~precise1 0         500 http://ppa.launchpad.net/brightbox/ruby-ng-experimental/ubuntu/ precise/main amd64 Packages  *** 1:1.2.3-1~38~precise1 0         100 /var/lib/dpkg/status      1.4.1-1ppa0~precise 0         500 http://ppa.launchpad.net/nginx/stable/ubuntu/ precise/main amd64 Packages      1.1.19-1ubuntu0.1 0         500 http://mirror.rackspace.co.uk/ubuntu/ precise-updates/universe amd64 Packages      1.1.19-1 0         500 http://mirror.rackspace.co.uk/ubuntu/ precise/universe amd64 Packages   How do I prioritize repo listed in nginx-source.list over the one which is on top of the list now ? I tried something like this:  $ cat /etc/apt/preferences Package: nginx-full Pin: origin http://ppa.launchpad.net/nginx/stable/ubuntu Pin-Priority: 1000  Package: nginx-full Pin: origin http://ppa.launchpad.net/brightbox/ruby-ng-experimental/ubuntu Pin-Priority: 100   But that has changed priorities of both sources to the same number - or something like that ? So this has NOT changed the priorities and nginx-full is still being installed form the brightbox PPA  $ apt-cache policy nginx-full   nginx-full:   Installed: 1:1.2.3-1~38~precise1   Candidate: 1:1.2.6-1~43~precise1   Package pin: (not found)   Version table:      1:1.2.6-1~43~precise1 1000         500 http://ppa.launchpad.net/brightbox/ruby-ng-experimental/ubuntu/ precise/main amd64 Packages  *** 1:1.2.3-1~38~precise1 1000         100 /var/lib/dpkg/status      1.4.1-1ppa0~precise 1000         500 http://ppa.launchpad.net/nginx/stable/ubuntu/ precise/main amd64 Packages      1.1.19-1ubuntu0.1 1000         500 http://mirror.rackspace.co.uk/ubuntu/ precise-updates/universe amd64 Packages      1.1.19-1 1000         500 http://mirror.rackspace.co.uk/ubuntu/ precise/universe amd64 Packages   Anyone has any idea how to achieve what I'm trying to do ? Can a creature with blindsight that is not immune to the Blinded condition suffer the effects of Blindness? Here is the situation that came up:  Player 1 controls a creature enchanted with  and two +1/+1 counters. On Player 2's turn, they cast  to take control of the creature, and then attack with it. The attack triggers the Ordeal, putting another +1/+1 counter on it. Now that it has three counters, it is sacrificed and a player gains 10 life.  Which player sacrifices the enchantment and gains 10 life? The controller of the creature (Player 2) or the player who cast the enchantment (Player 1)? I'm programming a presentation in LaTeX using the beamer class.  However, it defaults to 4:3 aspect ratio slides, while everything I use is 16:9.

Google Analytics reports 100% bounce rate for a page which has lots of page views and an Avg Time on Page of 32 seconds. Shouldn't one of the following be true?  Either the bounce rate is less than 100% when the Avg Time on Page is greater than 0 or the Avg Time on Page is 0 when the bounce rate is 100%.  I fail to see how or why the report does not conform the above two conditions. I am trying to build an executable jar program which depends on external jar downloaded. In my project, I included them in the build path and can be run and debug within eclipse.  When I tried to export it to a jar, I can run the program but I can't when I try to press a button which includes function calls and classes from the external jar. I have edited the environment variables (Windows XP) CLASSPATH to include paths of all the external jar, but it doesn't work.  A point to note is that I got compile warnings while exporting my executable jar, but it doesn't show up any description about the warnings.  Would someone kindly provide a thorough guide on how to include an external jar program using eclipse? I'm a committer for the .

I am looking for an adjective for a person who, no matter what you give him/her (materially or otherwise), is never content and always expects more. When to use reinterpret_cast? I am little confused with the applicability of reinterpret_cast vs static_cast. From what I have read the general rules are to use static cast when the types can be interpreted at compile time hence the word static. This is the cast the C++ compiler uses internally for implicit casts also.  reinterpret_casts are applicable in two scenarios:   convert integer types to pointer types and vice versa  convert one pointer type to another. The general idea I get is this is unportable and should be avoided.     Where I am a little confused is one usage which I need, I am calling C++ from C and the C code needs to hold on to the C++ object so basically it holds a void*. What cast should be used to convert between the void * and the Class type?  I have seen usage of both static_cast and reinterpret_cast? Though from what I have been reading it appears static is better as the cast can happen at compile time? Though it says to use reinterpret_cast to convert from one pointer type to another? Today I open my SO account like I always do. But the UI of menus has changed. I am not able to see the chat tab, the logout link or the privileges link. Are they missing or moved somewhere else?  Changed UI: Lowest voltage drop diode possible I am harvesting energy from an NFC device using a tuned antenna on my PCB. Though this method I am able to generate about 3.05V. I would like to charge a super capacitor using the power harvested from the NFC device. To do this I have  used the simple diode circuit provided  (and shown in Figure 1 below).  The problem I am facing is my circuit requires a minimum of 3V to operate within operating conditions, however with the added drop by typical diodes I believe there with be various situations where the generated voltage will drop below the required 3V. Are there any Diodes available which have ultra low voltage drops of less then 0.01V? and is that even possible?  Please note:   my system load will be &lt; 5mA  The 3.05V generated was without a diode in the circuit
