Front Disc Brake not braking to it's full potential

Hydraulic Disk brake piston not fully retracting My front disk brake's piston doesn't fully retract.  While I can ride the bike, the brake is slightly rubbing.  (IE, if I just spin the wheel with my hand, it'll go around about one and a half times and then stop.) It's definitely slowing me down.   If this fixable?  The advice I got was that it's not worth the trouble and to buy a replacement set.  The current brakes are Avid Juicy 7s that are about 7 years old How can I know what speed card to get for my camera? Cameras rarely specify exactly what speed cards you should be using in them - I just checked the manual for my DSLR, and all it says is to use an SDHD card, and a "high speed" card should be used for recording video.  On the other hand, there are a number of different rating systems for memory card speed (33x! 150x! Class 2! Class 10!) and price seems to increase with speed.  Is there any way to test the maximum write speed the camera is capable of?  Are the read/write speeds documented anywhere? Why did Kattappa kill Baahubali?

I have two User Accounts for my Windows 7 with no password requirement. I frequently use one of those accounts; so I would like Windows to log-on automatically with that account without the need for user input.  P.S. I don't prefer installing/using a third-party software for that purpose; especially those that place at low levels before Windows log-on.

My questions might seem naive as I haven't plunged into the mathematical descriptions, but wormholes are interesting even if I don't actually know them :)  First of all, is wormhole making two possible paths betwwen points (like the tunnel in most visualisations) or is it just making two points beside each other like in the game Portal? Of course, second case can be bent into a tunnel, but there would be nothing special about tunnel part and no preferred way to divide into "normal" and "tunnel" part of spacetime.  My main questions are these:   Is momentum conserved? Is kinetic energy conserved? How does potential energy work?   To elaborate... In the game Portal you can fall into floor and fly out of the wall or floor elsewhere with the same speed, but another direction (normal to the portal). So momentum is not conserved, but kinetic energy is. Is that how it would actually work? Where does the momentum go then?  And does it really allow you to increase your potential energy while retaining kinetic? It would seem fair to take away some kinetic energy if you are put in a region where you have more potential energy.  Either way is the change in energy non-continuous like in the game and discussion that's linked below? Or are there just more than one way to move through but the change in potential energy is smooth in any of those? That would mean more potential equilibrium points though...  Similar questions has been discussed , is it correct about how the falling guys gets a lot of energy (in form of a potential one) by draining it from the mouths? Number of zero digits in factorials Here is a riddle someone has been asked in a job interview: How many zero digits are there in $100!$?  Well, I found the first $24$ quite fast by counting how many times five divides $100!$ ($5$ divides $20$ times and $25$ divides it $4$ times).   However, there are more zero digits in the middle of the number (these can be found by hand, by typing factorial(100) in sage).  My question is whether there is a smart way to determine the number of zero digits in $100!$, and more generally in $n!$.  By the way, this will not affect the job interview as it was finished some time ago. Why does work depend on distance? Flow chart using Tikz- spanning multiple pages I am trying to create a flowchart with Tikz. Since it is a long one, it spans three pages. So after creating a node to stop, I am continuing to the next page using \newpage command. Unfortunately some elements in page 1 are connected to page 2, 3 and vice versa. So when I try to create the arrow connection, it is not possible since the \newpage command comes in between. I am sharing the code with you for info. Could  anyone help me to improve the flowchart so that I could direct the arrows among multiple pages. My sample code is below:  \begin{tikzpicture} \node 1 \node 2 ........ \draw[arrow] (node1)--(node2) \draw[arrow] (node2)--(node3) ---- \end tikzpicture} \newpage \begin{tikzpicture} \node 1 \node 2 ........ \draw[arrow] (node1)--(node2) \draw[arrow] (node2)--(node3) ---- \end tikzpicture} \newpage  \begin{tikzpicture} \node 1 \node 2 ........ \draw[arrow] (node1)--(node2) \draw[arrow] (node2)--(node3) ---- \end tikzpicture}
