The following picture appears on the  on :    My minimal knowledge of Star Trek tells me that these men are Captain Jean-Luc Picard (on the right), First Officer William Riker (on the left), and Lieutenant Worf (in the background), officers on the Enterprise during Star Trek TNG.  But where does this picture originate? Is it a screenshot taken from an episode of Star Trek? If so, which one? A Youtube clip including this scene would be great, if anyone has one!  Bonus points if you can explain why they're wearing funny hats: this picture's  is "404_funny_hats.jpg".
On the three Stack Overflow chat servers, the  page displays the following image:    Is it from an actual episode, or is it a 'shop?
How do I fix Outlook only showing the first line of every message? I'm experiencing a strange problem with Outlook 2019. When viewing a message it only shows the first line. On an HTML message, it stops at the first close paragraph tag. On a plaintext message, it stops at the first newline character. This is true if viewing a message in the reading pane as well as if double-clicking the message to open in its own window. I have the preview pane set to show 3 lines and it does show more of the message so it seems like Outlook can see more of the message than it's rendering in the reading pane. If I use View Source, the underlying data seems fine and the whole message is there. I've tried the following:  Deleting and re-creating the user's mail profile Uninstalling &amp; re-installing Office Creating a new Windows account &amp; connecting Outlook to a different Exchange account than the one that originally exhibited the problem Checked for Windows updates Checked for Office updates  Any ideas what might be causing this? I feel like I've tried everything obvious &amp; I'm striking out on Google. Shutdown button only logs out ubuntu 15.04 Removing nodes from graphs such that one is dependent on other - ZIO $2010$, P$1$ Greetings Community! The above problem you see is a combinatorics problem I could not solve. :( This problem is from ZIO $2010$, P$1$.     Here is what I did: Observe that every graph can be divided into "sub-groups" which may help in solving. We first remove the empty set. Then the singleton set. Consider the bigger but smaller than the sub-parts example:    The singleton sets are $\{4,5,6\}$ which are at the least position in the graph.   The dual sets are $\{2,4\}, \{3,5\}, \{3,6\}$, the bottom - two portions in the graph. The triplet sets are $\{2,4,5\}, \{4,5,6\}$ which we may manually count but for the bigger graphs in the sub-part, this may prove to be difficult and this is where I am stuck.   Any help would be appreciated. Thanks. I wish to print a Stack&lt;Integer&gt; object as nicely as the Eclipse debugger does (i.e. [1,2,3...]) but printing it with out = "output:" + stack doesn't return this nice result.  Just to clarify, I'm talking about Java's built-in collection so I can't override its toString().  How can I get a nice printable version of the stack? Is there a possibility to search when the embedded txt file was created in the word document? I'm working in Word 2010 and the extension of the document is simple: .doc  It was inserted using the Word options:  Insert -&gt; Object -&gt; Create from file -&gt; Insert as icon   Thank you, I already tried the right click and properties option, but the problem with it, that it shows only the current date for all of the 3 options (created/modified/accessed).           I also tried to get the timestamp but it is inactive when I'm on the txt object.   Sorry not to mention it before: Thank you all of you here for the help and support it is really appreciated. Looking for a science fiction story collection about nanotechnology — included a story about anti-graffiti paint I remember reading it while in middle school in English in the United States, so the latest it would have come out was 1998. I don't remember if it was all one author, or even the same universe. These are the stories I remember:   A man finds a way to create a medicine that prevents radiation poisoning (or possibly makes someone fireproof... it's a little confused in my head) and learns that part of the problem is finding a market for it. I vividly remember the inventor telling someone to not "let the doorknob ream you" as it slams shut. A bout of graffiti artists leads to the city buying anti-graffiti paint that dissolves any other paint put on top of it. After learning the futility of trying to paint over it, the protagonist consults with a friend and learns that the anti-graffiti paint will eat away at the paint above it at a steady rate, and will even eat successive layers of the anti-graffiti paint. he uses this property to engineer an animation involving a harlequin thumbing this nose at the officials even as they try to wash it away. Some guys (I want to say a gang) go to a clinic for an illegal nanotech transformation. The viewpoint character gets turned into a woman while a friend gets turned into a dog. After roaming about in their new forms, they return to find the clinic being raided, meaning there's no one to turn them back. I think I remember something bad happening to the one transformed into a dog where the transformation continued, erasing his human thought patterns. There was also a scene where the viewpoint character submitted to being sexually assaulted by his former friends as if it was simply to be expected given his form.   I don't remember if the first or the second story was the actual first story of the collection... I want to say that those are the order that they showed up as in the book. Given a filesystem path, is there a shorter way to extract the filename without its extension? I know there is a difference between assert and verify in Junit; the assert results in a runtime exception, causing test method execution to abort. To overcome this problem, we can have verify which will make test case fail, but allowing test execution to proceed rather than getting aborted.  I doubt there is any such built in approach in testNG. I do understand that best practices say, there should not be multiple asserts in same test case.  But, in practical world, we do come across scenarios where we need to have multiple checkpoints in one test case and we don't want our test method to abort because of one check point failure (test execution should proceed despite failure).  How can we use a soft assert mechanism, similar to verify, which will not abort test method when there is a checkpoint failure.  Example:  @Test(dataProvider = "getMailUrl") public void testMail(email,subject); Assert.assertFalse(subject.isEmpty);//1st checkpoint Assert.assertNotNull(email); //2nd checkpoint Assert.assertEquals(email, "feedback@yoursite.com"); //3rd checkpoint   Now, I want test execution to proceed, even if the 1st checkpoint (validation of subject being not empty) fails. Definitely we will be not be using assert (hard assert). We will need concept of soft assert similar to verify (facilitated by Junit).   I understand, we have to build a customListener implementing TestNG interfaces or extending existing listeners such as TestListenerAdapter. I am still struggling - how can we do this? Why does speed of light have to be constant? 80's/90's movie: man and woman driving through a red desert planet I am trying to identify a sci-fi movie from the 80's or 90's, with the following parameters:  Setting:    Scenes of a red desert planet   Culture:    Either people roam fairly solo and try to acquire resources to survive, or you live in a weird society where if a stranger is captured he needs to play in a game of fight to the death.  Mobility:      One foil character has a giant battle-bot-looking tank as his form of transportation through the desert. Protagonist has a car that has a plastic half bubble on top to look out from.   Robot:      The protagonist runs around in the beginning of the film with a female robot/android whose face is melted off after it has acid touch its face.(This scene happens next to the protagonist's rover)  Love interest:      Somehow protagonist comes across female protagonist in desert. She smells really bad and is hungry. They sleep outside, and he tells her to sleep away from him. He uses a thermal blanket(the first I ever saw in my life). She wakes up next to him, smelling horrible. He bathes her in some water hole they find(as if water were not scarce and they could just waste water.)   Pupa monsters:      Scene where they are in a building and they are trying to get out. They come across a room that is white, in which multiple giant, white, snot, pupa are hanging securely from the ceiling. Through curiosity, they disturb them, and now they have to get out of that room fast.  Boss Antagonist:      Pervert bionic man, that is actually attached to a giant robotic arm, as only form of movement. He is in black and has a pale bald head as his most human looking part. Mouse cursor doesn't change to pointer when hovering "full site" on mobile When (accidentally) clicking "mobile" in the footer, one gets the mobile site in a regular browser too. To switch back, one can click "full site" in that same footer:    However: when hovering it, the mouse is changed as to select text, rather than to indicate one can click (even though it's clickable).  All other links do change the mouse into a pointer.  (Not a big deal, except when somehow  getting into the mobile mode, I guess.) Matrices: system that is "computationally singular" versus "exactly singular" I would like to know the mathematical concepts behind singular matrices. Matrices that do not have inverses in R throw one of two errors. I have provided some examples of both errors below:    Error in solve.default(W) :  system is computationally singular: reciprocal condition number = 1.58603e-17   Error in solve.default(Z) :  Lapack routine dgesv: system is exactly singular: U[2,2] = 0    Can anyone explain the difference between the two? Why is the first "nearly singular" whereas the second is "exactly singular"? Why do I get "Required key not available" when install 3rd party kernel modules or after a kernel upgrade? How do you associate the .exe file extension with a program in Windows? What's the difference between \usepackage{ngerman} and \usepackage[ngerman]{babel} How to prove $\bar{m}$ is a zero divisor in $\mathbb{Z}_n$ if and only if $m,n$ are not coprime Let us consider the ring $\mathbb{Z}_n$ where $\bar{m}\in\mathbb{Z}_n$  Could anyone help me prove that $\bar{m}$ is a zero divisor in $\mathbb{Z}_n$ if and only if $m,n$ are not coprime  So far I have:  Assume $\exists \bar{a}: \bar{m} \bar{n}=n \mathbb{Z} \Rightarrow$ for some $b\in\mathbb{Z}:am=bn$  I then assumed $n,m$ were coprime and attempted to use $\exists a&#39;,b&#39;\in \mathbb{Z}:a&#39;m+b&#39;n=1$ to come to a contradiction, however haven't found one, the most promising thing I have found so far is that  $a=n(a&#39;b+ab&#39;)$ and $b=m(a&#39;b+ab&#39;)$ $\Rightarrow n|a$ and $m|b$ Why, microscopically, is the voltage drop across a resistor affected by the current through it? If voltage is a potential difference, describing how much energy will be lost per unit charge as charge carriers pass through the resistor, why would the rate at which charge flows (i.e. current, $=dq/dt$) affect the amount of energy lost per unit charge?  I suppose I am asking why a quasi-"extensive" property of the system (current) would affect a quasi-"intensive" property of the system (voltage drop across the resistor).  Apologies if the answer is obvious; I was having trouble understanding why the rate of charge flow would factor into voltage drop whilst trying to rationalize Ohm's law for myself. What I am working with: I am running my self-made Arduino board (in the sense that I use the Arduino bootloader and code editor) at 3.3V, and powered from a Lithium ion battery, which is USB-charged by a corresponding Microchip charger IC.  What I am trying to achieve: I want to measure battery capacity once every minute or so. I have an LCD attached, so the idea is that the overall setup lets me know how the battery is doing at a given moment. The datasheet of the battery has a voltage versus discharge-level curve, and so by measuring the voltage of the battery, I can estimate the remaining capacity (very roughly but enough for me!).  What I did:   (EDIT: Resistor values updated and P-MOSFET switch added based on @stevenvh and @Jonny's suggestions).  I connected a voltage divider from the battery V_plus, with the larger "portion" going to an analog-read-pin (i.e., ADC) on the Arduino/Atmega chip. The divider is 33 KOhm-to-10 KOhm, thus allowing measurement up to 4.1 Volts maximum of the Li-ion battery from my 3.3V level microcontroller. Also, using one of the I/O pins connected to an n-channel MOSFET, I can switch the current through the divider only when I need the measurement. Here is a rough schematic (updated for a 2nd time based on suggestions of @stevenvh and @Nick):     My question:   How is my current setup? My only constraints are: (1) I would like to make a rough measurement of the battery capacity based on the voltage reading, as described above. (2) I would like to prevent the voltage divider from interfering with my charging IC's reading of battery presence (in my original setup, the divider sometimes caused the IC to misread presence even when the battery was absent). More than once I've accidentally run a number of commands and polluted my bash history. How do I close my terminal without saving my bash history? I'm using Fedora. Prove $n-m \mid n^r - m^r\,$ [Factor Theorem, monomial case] In respect to a larger proof I need to prove that $(n-m) \mid (n^r - m^r) $ (where $\mid$ means divides, i.e., $a \mid b$ means that $b$ modulus $a$ = $0$). I have played around with this for a while now but to no avail and would be grateful if you could help me.
