The hyperphysics article defines osmosis as a process driven by internal energy and internal energy is defined as energy associated with random,disordered motion of molecules. Osmosis develops pressure and lifts weight so it has the output of a machine.  But what drives osmosis? Is osmosis driven at the expense of thermal energy although there is no temperature gradient? For a certain Hibernate entity we have a requirement to store its creation time and the last time it was updated.  How would you design this?   What data types would you use in the database (assuming MySQL, possibly in a different timezone that the JVM)?  Will the data types be timezone-aware? What data types would you use in Java (Date, Calendar, long, ...)? Whom would you make responsible for setting the timestamps&mdash;the database, the ORM framework (Hibernate), or the application programmer? What annotations would you use for the mapping (e.g. @Temporal)?   I'm not only looking for a working solution, but for a safe and well-designed solution. Ignore Pulses Less than a Given Width in a Pulse Train Let's say I have a 5V pulse train that varies between 0 and 75000 pulses per second. Pulse width, let's say, is 5 microseconds. How could I calculate or determine the best way to filter out all pulses less than 4 microseconds in width? Is there a name for this type of sentence structure: "She looks as though she's been poured into her clothes, and forgot to say 'when'"? Comedians seem to use phrases that employ this type of sentence structure - is there a name for it?  Examples of Groucho Marx's one liners seem to fit this pattern — and if memory serves, Emo Philips.       One morning I shot an elephant in my pajamas, how he got in my pajamas, I don't know.     I've had a perfectly wonderful evening, but this wasn't it. Traditional search-as-you-type on newer Nautilus versions Until now I was using a "traditional" version of Nautilus: that that comes with Ubuntu 10.10. Now I'm using 3.6.3, included with Ubuntu 13.04 (most likely any recent version is equivalent for the scope of my question, anyway).  One major difference between the two is the search-as-you-type behavior: in classic versions of Nautilus, when you typed an input, the file with the closest alphabetical match would become the selected one, the eligible files/folders being restricted to the current directory.  The new behavior is to perform an optionally-global search instead.  Can one configure Nautilus to provide the previous functionality ? While we know that every finite set is compact, how to prove that every infinite subset of $\mathbf{R}$, the set of all real numbers, is also compact in the finite-complement topology (also called the co-finite topology)?   What is the situation in the case of an arbitrary infinite set $X$ with the finite-complement topology? I have this alias set in my system /etc/bashrc file:  alias root="sudo !!"   The intention of this being to run the last used command using sudo of course. When used, it of course appears to substitute the last command in history to the bashrc file upon shell initialization, and not the actual command that you would get if you were to run sudo !! in an interactive shell. I've also tried alias root="sudo fc -s" to no avail.  I realize this is probably something to do with how the BASH does command substitutions, but can someone explain why this is, and provide a usable substitute?  I'm running BASH version 3.2.51(1)-release (x86_64-apple-darwin13). How should I use "eponym", "eponymous" and "namesake"? I was in London and visited the Tower Bridge. Afterwards, I went to a pub called The Tower Bridge. Just to be clear, the pub is named after the bridge.   Which of the following are correct?   The bridge is the eponym of the pub. The pub is the eponym of the bridge. From the pub, I could see the eponymous bridge. After I saw the bridge, I went to the eponymous pub. The bridge is the namesake of the pub. The pub is the namesake of the bridge. Probability distribution in the coupon collector's problem I'm trying to solve the well known Coupon Collector's Problem by explicitly finding the probability distribution (so far all the methods I read involve using some sort of trick). However, I'm not having much luck getting anywhere as combinatorics is not something I'm particularly good at.   The Coupon Collector's Problem is stated as:  There are $m$ different kinds of coupons to be collected from boxes. Assuming each type of coupon is equally likely to be found per box, what's the expected amount of boxes one has to buy to collect all types of coupons?  What I'm attempting:  Let $N$ be the random variable associated with the number of boxes one has to buy to find all coupons. Then $P(N=n)=\frac{|A_n|}{|\Omega _n|}$, where $A_n$ is the set of all outcomes such that all types of coupons are observed in $n$ buys, and $\Omega _n$ is the set of all the possible outcomes in $n$ buys. I think $|\Omega _n| = m^n$, but I'm not even sure about that anymore, as all my attempts so far led to garbage probabilities that either diverged or didn't sum up to 1. Humorous time travel short story about a man's dealings with other versions of himself Okay, similar questions to this have been asked before, but not about the particular short story I am trying to find.  It was in an anthology of short sci fi stories, possibly award winning ones or at least someone's compilation of favourites. (I think)   It was a long time ago, maybe 1970s or 80s, so the story could date back to even the 1960s for all I know, but probably the 1970s.  It was the funniest story about time travel where a person meets incarnations of himself, that I have ever read. It was either derivative of 'By His Bootstraps' or the other way around, but my recollection is that this story was funnier.  Maybe my memory is playing tricks on me and it WAS 'By His Bootsraps', but I am almost certain that it wasn't, because when I read that recently it seemed unfamiliar and not as funny.  In the one I am trying to recall, the guy is also bemused and irritated by the behaviour of other incarnations of himself, like the Heinlen story, but the repartee between versions of himself and his extreme frustration is much more hilarious.  I have a vague recollection that he is in a spaceship during the story, but not absolutely sure. There seemed to be a lot of clambering around, ladders, bulkheads, etc, unlike the Heinlen story.  I'm almost certain it isn't any of the commonly suggested stories and I'm quite sure it wasn't a short film where he shoots his older self, or a full length novel. Someone will have read it and (un)remembered it fondly like me, I feel sure! Why is there a peeking duck in my profile pic? In , you may see something odd: a peeking duck.    I've just recently uploaded this new profile picture of mine. I checked it after the upload and everything's fine. After a few hours, I opened my profile and there it is, the duck has somehow become afraid of the people viewing it.  Is this a bug, a feature, or is it just the duck?  I am about to re-upload my profile pic, but I've decided to drop first this topic to meta.  And if you're curious,  is the original picture.    ADDITIONAL: I've used the non-gravatar way to upload the picture.  ADDITIONAL 2: The problem only shows in the profile view. No problem in chat, less info profile view, and in the questions and answers.  UPDATE: Re-uploaded picture. Status normal (for now, at least). How to remove comma and "and" before institutional last author after compiling BibTeX I have the following BibTeX entry:  @article{pubmed18800157,     author = {Heng, T.S. and Painter, M.W. and Immunological Genome Project Consortium},     title = {The {I}mmunological {G}enome {P}roject: networks of gene expression in immune cells.},     journal = {Nat. Immunol.},     pages = {1091-1094},     volume = {9},     number ={10},     year = {2008}, }, %\bibliographystyle{unsrt}   When the bibliography is generated, it puts comma a the end of the author:   Notice the comma after M.W. Painter. Is there a way to remove it? How to tell Max CP? Assume $\bar A\cap\bar B=\emptyset$. Is $\partial (A \cup B)=\partial A\cup\partial B$, where $\partial A$ and $\bar A$ mean the boundary set and closure of set $A$?   I can prove that $\partial (A \cup B)\subset \partial A\cup\partial B$ but for proving $\partial A\cup\partial B\subset \partial (A \cup B)$ it seems not trivial. I tried to show that for $x\in \partial A\cup\partial B$ WLOG, $x\in \partial A$ so $B(x)\cap A$ and $B(x)\cap A^c$ not equal to $\emptyset$ but it seems not enough to show the result. Lightning component scripts loading issues since Spring 17 update Capillary action and conservation of energy When I dip a paper towel in a cup of water the water gets drawn up due to . How is this reconciled with conservation of energy, as it would seem on the surface that the potential energy of the system has gone up with no work being done? When is it correct to use the "-wise" suffix? I have a canon 760D. It has a EF-S lens mount. Am I able to use a EF lens with my camera?
