Is there a word for a person that is tender as well as strict at times or as per situation?  A word that could be used for a teacher or maybe a mother.     Although she was (like)  ________, she was the best.   I usually compare them to being like a coconut (hard from the outside but soft in the inside) since I don't have a better alternative.  Please add suitable idioms if available, I'd be extremely grateful.
A person who speaks kindly. Sometimes she might be hard, but fair.   What is an adjective to describe such person?
How can I replace a relay with a MOSFET Transistor? I have this working         &ndash; Schematic created using   An Arduino commute both relays and a power adapter charge each battery at a time.  I would like to replace each relay by a MOSFET. How can I do that?  I think the solution bellow will not work because DRAIN is always connected to SOURCE and this will short circuit batteries. MOSFETS only isolate from SOURCE to DRAIN.  When the D9 is HIGH, D10 will be LOW so the power adapter will never be charging both batteries simultaneously.          Sorry for the messy schematic.  Thank you very much. How to set Ubuntu to synchronize my clock with a time server? Escape velocity from long ladder How do I pre-install Ubuntu for someone (OEM install)? "Show desktop" keyboard shortcut in Mac OS X I am using a MacBook Pro with Mac OS X 10.5. Is there a similar function to "show desktop" (shortcut is WIN+D) on a Mac?   It should hide all applications and show a clean desktop.

BasicTeX - how to identify packages that need to be added after an upgrade 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 I normally dual-boot with 12.04 and Win XP pro sp3 on a Thinkpad R60.  I needed to reinstall windows because of problems piling up, so I ran the computer's built-in hard-disk recovery software.  I told it not to mess with the other partitions, but somehow it deleted the Linux partition.  That's what I was using to backup all of my windows files, so now everything I have is gone.  I just ran the USB setup with linux, and the partition is deleted - it just shows it as empty space.    Is there ANY way to get all of my files back? How, on a physical level, does ATP confer energy? When ATP is used as the energy currency to make, say, reaction X + Y → Z happen, is what happens on a physical level down at the molecular scale that during the reaction    ATP + H2O → ADP + Pi &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ΔG˚ = −30.5 kJ/mol (−7.3 kcal/mol)    that 30.5 kJ/ mol is conferred by ATP molecules physically bumping around the reactants X and Y, the kinetic energy of the above reaction being what does it?  I mean, is the energy coin of ATP conferred to reactions by molecular collisions, or is it an electric field effect in the spatial geometry the way the ATP molecule tends to break apart? I am using tufte-latex package, which uses mathpazo with old style numerals. To make figures (plots) I would like to use lining numbers.  The problem is that the figures are converted from svg to pdf using inkscape and the numbers are not in mathmode (In math mode the numbers are lining numerals by default).  I think of two possible solutions:  a) Is there any command similar to \oldstylenums that does the opposite work?  b) inkscape put the text of the figure in \smash{-22.22} commands. Is any way,  using sed, awk, perl,... to change that to \smash{$-22.22}? The external Flash is not showing up in the configuration Menu when using Pixel TF-321 hot shoe. Is this the wrong adapter for that camera, as there is no X connection? I want to trigger a studio flash via sync connection. Can you recommend me a working hot shoe? Thanks! How to get text under mouse in any open window How do I increase the size of swapfile without removing it in the terminal? Is there a way to increase my existing "swapfile" without having to destroy and re-create it? I would like to up my swap space from 1GB to 2GB.  Currently it is set up as such:  $ sudo swapon -s Filename                Type        Size    Used    Priority /swapfile               file        1048572 736640  -1 $ ls -lh /swapfile -rw------- 1 root root 1.0G Nov  9  2016 /swapfile   I'm using Ubuntu 14.04. How to highlight paragraph (linebreak preserving) as well as itemize, tabular etc.? I want to highlight changes which are introduced by myself in the pdf document. So far the soul package is very neat but it does throw errors when I want to highlight not only paragraphs but also some itemize environments, and I don't want to highlight the items separately. Also the \cite{...} command is not supported by \hl. I recently posted a slightly different question:   BTW: What I liked most over other approaches like pdfcomments etc. is that the \hl command from soul has a very exact and clear output, no icons, no clicking etc. involved. Together with todonotes it's very good and almost all I need. I'm trying to condense the space around examples in gb4e, with the goal of removing unnecessary whitespace around examples in an abstract. Here's what gb4e gives me now:    What I'd like is for the examples to essentially look like part of the running text, as follows:    In sum, I'd like to remove the left indent before the top level item numbers, remove the vertical space between examples, and remove the vertical space above and below the exe environment.  I think \vspace commands might work here, but it would get very tedious to do this every time, and I'd also like to do it the 'right' way.  (I also think linguex might be able to do this without too much fuss, but I'm used to using gb4e so I'd prefer to stick with it if there's a way to do this.)  MWE:  \documentclass{article}  \usepackage{gb4e} \usepackage{lipsum}  \begin{document}     \lipsum[1]     \begin{exe}         \ex Blah \begin{xlist}             \ex Blah             \ex Blah         \end{xlist}         \ex Blah         \ex Blah     \end{exe}     \lipsum[1] \end{document} Fermi in his lecture asserts:     The second law of thermodynamics rules out the possibility of constructing a perpetuum mobile of the second kind.   So, this means there can be no machine which just transforms all the heat energy gained by cooling surrounding bodies into mechanical work.  But how does actually the Second Law prohibit this?   The hot reservoir provides heat energy to the system. Does it cause a decrease in entropy of the universe(system + hot reservoir)? How? In order to receive heat wouldn't the system have to be cooler than the reservoir? If so, then entropy increases as the heat energy gets expelled from the reservoir at a higher temperature than the temperature the system receives the heat energy. Is it so?  I'm not getting how the Second Law nullifies the existence of this machine. Could anyone please explain how the Law prohibits the perpetual machine of the second kind?

This almost structure may be chosen integrable?  I ask because there are certain known results on the different possible geometries in dimension 2.I don' t know exactly how these manifolds (closed and orientable) are classifyied, but I know there are three cases. May be I am confused, and the complex structure is irrelevant to this classification. Some help please! Can't convert string into float/double
