Shorthand for `short` type?
How to specify a short int literal without casting?
Quick Look support for non-native video files (.avi, .mkv) on Mavericks In the past, we've been able to get codecs for DivX/XviD/MPEG4 and support for containers like AVI, MKV in Mac OS X's Quick Look feature using  (as per ).  As noted on the Perian site, development has ceased, and future versions may or may not continue to work. It seems with the upgrade to OS X 10.9 "Mavericks", the OS or Quick Look API has changed sufficiently that Perian no longer works.  Are there any alternatives? Ideally a one-app-does-all like Perian, but even a list of individual codecs and/or plug-ins for video container files would be useful.  NB: This question isn't about video players—there are many that support more than those playable via the built-in QuickTime player. This question is about codecs/plug-ins for QuickTime on OS X to allow it and Quick Look (and apps which rely on the OS to play videos) to open/play video files/formats lacking native support. Let $X$ be a random variable and let $g,f$ be real-valued, nondecreasing, and bounded.   Show that $\mathbb{E}[f(X)g(X)]\geq \mathbb{E}[f(X)]\mathbb{E}[g(X)]$  Having a hard time seeing where to start for some reasons, any hints?  I managed to write:  $\mathbb{E}[f(X)g(X)] = \frac{1}{4}\mathbb{E}[(f(X)+g(X))^2 - (f(X)-g(X))^2]$  But I'm not sure if this is in the right direction or not. LED as power generator Is it possible to colour or put textures on Bevel curves? So with my model, I've been struggling to create hair because it always looked weird or off and recently I discovered the "Bevel Curve" addon and it's an absolute lifesaver.   So I converted the bevels into mesh to colour it, except it lags blender like crazy and I need this model for a video game I'm currently developing called Candles(so I can't upload the model, sorry) but I was wondering, is it possible to put a texture on a bevel curve like you would mesh or any other method or giving it colour? Segmentation fault with strcpy() A proof using Yoneda lemma Substitute fresh garlic instead of garlic powder? I have a recipe that calls for garlic powder, but I only have fresh garlic on hand.   What ratio should I use to substitute? What happens if I use RAM of a faster speed than the CPU supports? Looking at the  CPU, under Memory types it says "DDR3-1333/1600". My question is, in what way does the CPU limit the RAM speed? What would happen if I put in a DDR3-2133 RAM chip together with the CPU, if the motherboard supports the faster RAM speed? Would it be better to get a RAM chip that is DDR3-1600 so it matches the CPU's listed frequency? I understand that a black hole bends the fabric of space time to a point that no object can escape.   I understand that light travels in a straight line along spacetime unless distorted by gravity. If spacetime is being curved by gravity then light should follow that bend in spacetime.  In Newton's Law of Universal Gravitation, the mass of both objects must be entered, but photon has no mass, why should a massless photon  be affected by gravity in by Newton's equations?

Actual seismograph electronics are very expensive. I'm just wondering if a seismograph can be made with a adequately semsitive accelerometer. To be exact I want to bury the accelerometer based seismograph and have it sense footsteps.  So is this possible and what method would you reccommend for my needs and why? enumitem breaks beamer's itemize despite fixes I thought I had tamed enumitem. I had this  and this .  Then I tried a [&lt;+-&gt;] construct. It failed. Commmenting the enumitem section prevents errors but I'd rather not have to do this.  On its current state, this code produces two errors, one because of the [&lt;+-&gt;] and another because of the \onslide.   \documentclass{beamer}   \usepackage{enumitem}  \setitemize{label=\usebeamerfont*{itemize item}%    \usebeamercolor[fg]{itemize item}    \usebeamertemplate{itemize item}}%https://tex.stackexchange.com/a/24491  \setenumerate[1]{%    label=\protect\usebeamerfont{enumerate item}%          \protect\usebeamercolor[fg]{enumerate item}%          \insertenumlabel.}%https://tex.stackexchange.com/a/45950   \begin{document}  \begin{frame}  \begin{itemize}[&lt;+-&gt;]  \item 1  \item 2  \end{itemize}  \onslide&lt;2&gt;{text}  \end{frame}  \end{document} I've seen lots of examples of making an entire regular expression case-insensitive.  What I'm wondering about is having just part of the expression be case-insensitive.  For example, let's say I have a string like this:  fooFOOfOoFoOBARBARbarbarbAr   What if I want to match all occurrences of "foo" regardless of case but I only want to match the upper-case "BAR"s?  The ideal solution would be something that works across regex flavors but I'm interested in hearing language-specific ones as well (Thanks )  Edit  The link Espo provided was very helpful.  There's a good example in there about turning modifiers on and off within the expression.  For my contrived example, I can do something like this:  (?i)foo*(?-i)|BAR   which makes the match case-insensitive for just the foo portion of the match.  That seemed to work in most regex implementations except Javascript, Python, and a few others (as Espo mentioned).    The big ones that I was wondering about (Perl, PHP, .NET) all support inline mode changes. Why is $1 in a function not printing the script's first argument? Why doesn't echo $1 print $1 in this simple bash script?    #!/bin/bash # function.sh print_something () { echo $1 } print_something  $ ./function.sh 123  -&gt; why doesn't it print '123' as a result? I'm having troubles with rendering my datatable correctly. There are actions added but it seems the datatable is not high enough to view it correctly. Is it something I'm doing wrong? Or is it a bug?    This is the code for the datatable  &lt;div class="slds-text-heading_medium"&gt;Search results&lt;/div&gt; &lt;lightning:datatable data="{! v.persondata }"                      columns="{! v.personcolumns }"                      keyField="id"                     onrowselection="{! c.getSelectedPerson }"                     hideCheckboxColumn="true"  /&gt;   Here is the code for initializing the columns  //init datatable component.set('v.personcolumns', [             {label: 'Last Name', fieldName: 'LastName', type: 'text'},             {label: 'First Name', fieldName: 'FirstName', type: 'text'},             {label: 'Mailing Zip/ Postal Code', fieldName: 'PersonMailingPostalCode', type: 'text'},             {label: 'Mailing City', fieldName: 'PersonMailingCity', type: 'text'},             {label: 'Billing Street', fieldName: 'PersonMailingStreet', type: 'text'},             {label: 'Email', fieldName: 'PersonEmail', type: 'text'},             {label: 'Primary Phone', fieldName: 'PersonHomePhone', type: 'text'},             {label: 'Secondary Phone', fieldName: 'PersonOtherPhone', type: 'text'},             {type: 'action', typeAttributes: { rowActions: actions}}         ]);   And the code for adding data (the response is a list of Accounts)  component.set('v.persondata',response.getReturnValue()); "I think him to be about 50" or "I think he is about 50"? SINGLE_EMAIL_LIMIT_EXCEEDED. What does it mean? I am new to data analysis and now working on a Mixed Effects Logistic Regression Model.  Currently, I have the following data frame (model_data):  Road Id Vehicle_id  entry_time           exit_time          1        1        2017-01-31 00:00:00  2017-01-31 00:00:00 last_veh_time  vehicle_type     status 300            4 wheel          0    Likewise, I have the information (nearly a million rows) of all the vehicles entering a place and exiting the same place.  Status can be either $1$ or $0$ for all of these.  last_veh_time is the last vehicle passed the same place before how much time.    I want to know the probability of a getting status $0$ for a vehicle based on the entry_time and last_veh_time. To do this, I created the model:   model = glmer(status ~last_veh_time + (1 |link ),               data=model_data, REML=FALSE)   Is this the right approach?  Any help is appreciated. Order of a homomorphism of groups Show that the set of all finite subsets of $\mathbb{N}$ is countable. Show that the set of all finite subsets of $\mathbb{N}$ is countable.   I'm not sure how to do this problem. I keep trying to think of an explicit formula for 1-1 correspondence like adding all the elements in each subset and sending that sum to itself in the natural numbers, but that wouldn't be 1-1 because, for example, the set {1,2,3} would send to 6 and so would the set {2,4}.  Multiplying all the elements in each subset and sending that product to itself in the natural numbers wouldn't work either since, for example, {2,3} would send to 5 and so would the set {1,5}. Any ideas?
