Why do we need to discard one dummy variable? Sci Fi action movie where an elite group of people control business through a game they play online In Windows, you can run android application using BlueStack.   I was wondering, is there any way these apps can be run on Ubuntu 12.04? Encopresis, I'm at my wits end? Does anybody have suggestions? What are the rations Rey eats? In The Force Awakens, we see Rey pouring some flour-like polystarch rations into water so that the flour amazingly transforms into something that looks like bread. What are these rations? Is there any documentation of the fictional chemistry and biology that makes the starch rations behave as they do? Which hydroxyl from either the phosphate or the glycerol is taken during synthesis of a phospholipid head? I noticed that if I run ls -F on a directory, some of the entries have a * or a @ after them.   spuder@ubuntu:~$ ls -F /sbin acpi_available*   getpcaps*           lvmconf*                 ntfscp*        start-stop-daemon* agetty*           getty*              lvmdiskscan@             ntfslabel*     status@ alsa*             halt@               lvmdump*                 ntfsresize*    stop@ alsactl*          hdparm*             lvmsadc@      spuder@ubuntu:~$ ls -F ~ daq-0.6.1/  examples.desktop       noname-cache.lib  snort-2.9.1/   Templates/ Desktop/    jpgraph-1.27.1/        noname.sch        snortfiles/    Ubuntu One/ Documents/     According to the ls man pages   spuder@ubuntu:~$ man ls ... -F, --classify   append indicator (one of */=&gt;@|) to entries ...   I'm guessing that @ means symbolic link,     What do these other indicators mean ( */=&gt;@| )  ? A good title helps your question get the attention it deserves.  What goes into a good title? Let $\mathbf{Y}$ be a random vector. Are $k$th moments of $\mathbf{Y}$ considered? I am self-learning on linear model theory right now, and one thing I find surprising is that although $\mathbb{E}[\mathbf{Y}]$ is defined for a random vector $\mathbf{Y} = \begin{bmatrix} y_1 \\ y_2 \\ \vdots \\ y_n\end{bmatrix}$, there is no mention of further moments besides the covariance matrix.  Google searching hasn't turned up much. Are $k$th (raw) moments of $\mathbf{Y}$ considered, or is there a different idea I don't know about?  I am learning from the text  (the TOC starts in p. 17 of the linked file). By "considered," what I mean is is there such a thing as $\mathbb{E}\left[\mathbf{Y}^k\right]$, and if so, how would such a concept be defined? The book I have only covers the first raw moment, and I find it a bit strange that there is no mention of how to define $\mathbb{E}\left[\mathbf{Y}^k\right]$ given my experience in univariate probability, nor do I have the expertise to define it.  Furthermore, if $\mathbb{E}\left[\mathbf{Y}^k\right]$ isn't defined, is there perhaps a related concept that I don't know about that is used instead? What causes "java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'command' available as request attribute"? Switching to different font size(s) locally 16.04 new installation gives grub-efi-amd64-signed failed installation /target/ ubuntu 16.04 at the end I am installing Ubuntu 16.04 in an Intel NUC computer with UEFI enabled. I am using an SSD from another computer. During the installation I chose Erase the disk and make a new full install  At the end of the process I see:  grub-efi-amd64-signed failed installation /target/ Ubuntu 16.04    And the system does not boot.  I tried to use boot-repair but apparently it does not solve the problem. The hidden flaw in "singular they"—what to do about reflexive pronouns? We have  to a question about gender-neutral pronouns, in which he points to the "singular they" and its long history of use in English. (Note that he also advises against using it.) Example:     If someone wants to watch TV tonight, they'll have to do the dishes.   This avoids having to say "he or she" in mixed-gender situations. Okay, fine. I'm not going to get my panties in a bunch if people want to talk this way.  But it occurrs to me that "singular they"—infelicitous at the best of times—really falls apart when extended into the realm of reflexive pronouns:     If someone wants to watch TV tonight, they'll have to do the dishes all by themselves. [?]   That feels very wrong. The only alternative, if one paints oneself into that corner, is to flip it back to singular:     If someone wants to watch TV tonight, they'll have to do the dishes all by themself. [???]   That feels worse.  If I'm to state this as a question, I guess I would put it thus: How can use of a "singular they" truly be reconciled? Is it really as much of a linguistic dead end as it feels to me? Is there a C++ decompiler? Name for the center amplitude of a sine wave I am trying to find the name for the value at the center of a sine wave $$ y(t) = A\sin (kx \pm \omega t+\varphi) + D $$ i.e. the offset $D$ of the wave in the $y$-direction.  calls it Center Amplitude, but further googling this name is difficult and does not provide any further sources. I also found the expression , but I'm not sure that it refers to the same thing. Is there a commonly used name for the $y$-direction-offset of a sine wave? Same Video on each face, but with different time delay? iam looking for a way to - like the title says - i want to put the same video on each face, but with different time delay.  In other words, i want to create a kind  of videowall.  i found :  #---------------------------------------------------------- # File multi_material.py #---------------------------------------------------------- import bpy  def run(origin):     # Create three materials     red = bpy.data.materials.new('Red')     red.diffuse_color = (1,0,0)     blue = bpy.data.materials.new('Blue')     blue.diffuse_color = (0,0,1)     yellow = bpy.data.materials.new('Yellow')     yellow.diffuse_color = (1,1,0)      # Create mesh and assign materials     bpy.ops.mesh.primitive_uv_sphere_add(         segments = 16,         ring_count = 8,          location=origin)     ob = bpy.context.object     ob.name = 'MultiMatSphere'     me = ob.data     me.materials.append(red)     me.materials.append(blue)     me.materials.append(yellow)      # Assign materials to faces     for f in me.faces:         f.material_index = f.index % 3      # Set left half of sphere smooth, right half flat shading     for f in me.faces:         f.use_smooth = (f.center[0] &lt; 0)  if __name__ == "__main__":     run((0,0,0))   But it didn't really work out for me, it creates a red sphere and sends      Traceback (most recent call last):   File "\Text", line 36, in      File "\Text", line 28, in run AttributeError: 'Mesh' object   has no attribute 'faces' Error: Python script fail, look in the   console for now...   to the console.

If they do exist in .NET, could you please provide a code snippet (preferably in C#) explaining it? Exporting Data From Salesforce - REST or SOAP? We have a requirement where we need to export records from salesforce tables into our application programmatically. I am reading on the various API's for data integration from salesforce mainly SOAP vs REST API's.  From what I understand, REST should be used when the web service requests are from mobile devices or browser based clients (since they understand JSON). Is that true? If that's the case how do Bulk REST API's fit the bill (since they are meant for bulk data transfers)?  I would like to get your thoughts on what are pros and cons in using SOAP or REST API's to export data records. Note that the requests are being made a java ee server application programmatically. After retrieving the records (probably in batches) from salesforce records we process (validate, filter etc) them and load them in our internal tables.  Thanks. Does anybody know of a method to trigger an event in Prototype, as you can with jQuery's trigger function?  I have bound an event listener using the observe method, but I would also like to be able to fire the event programatically.  Thanks in advance Given two positive integers $a$ and $b$, prove that  $\sum_{k=0}^{n} {k \choose a} {n-k \choose b} = {n+1\choose a+b+1}$  I think there should be a good combinatorial proof for this, given the simplicity of the right-hand side... my hunch is to form all possible subsets of size $a+b+1$ by dividing the set into $k$ and $n-k$ elements, then choosing $a$ from the first, $b$ from the second, iterating over all values of $k$.  I can't quite make this work, so I've also been trying to rewrite ${n+1 \choose a+b+1}$ to make it clear.  Open to any proof method, all help appreciated.
