From the TV Show Krypton, Dru-Zod is the son of Seg-El and Lyta-Zod. In the last episode, Seg manages to trap Brainiac inside the Phantom Zone but unfortunately Brainiac manages to take Seg along with him just before the portal gets destroyed. Shouldn't Dru-Zod by wiped from existence because Seg is now in the Phantom Zone? Or did Lyta-Zod get pregnant before Seg got taken into the Phantom Zone?
From the TV Show Krypton, Dru-Zod is the son of Seg-El and Lyta-Zod. In S02E05 'A better yesterday', Lyta-Zod's throat gets slit by Jax-Ur leading to Lyta's death. How is Dru-Zod still alive? Shouldn't he be wiped from existence?
Old TV mini-series with a living brain in a lab Which Standard Visitor visa should I apply for? I accidentally deleted a file from my laptop. I'm using Fedora. Is it possible to recover the file? When and why did Harry Potter fall in love with Ginny Weasley? In the earlier HP books it's pretty clear that Harry and Ginny get on quite well as friends (and that she's rather smitten with him) but I'm struggling to identify when and why Harry started to like Ginny in a romantic fashion..  I feel like it is simply presumed that Harry suddenly likes Ginny Weasley back, but do the books actually describe when and why he started to like her that way?  No speculation, please. Canon answers only. I am supposed to integrate $f(z)=$$\frac{5}{z}$ from -3 t0 3 but I am having trouble understanding how to do this. I've done the integration the "hard" way by using parametrizations but now I need to use the fact that $f(z)$ is analytic everywhere except at $z=0$ and a different method to perform the integration but I am stumped. Why are all of Mr. Shirley's gifts the same? Acer Aspire E15 will not dual boot I installed Ubuntu 14.04 onto my Acer Aspire E15. The PC has a 500 Gigabyte HDD.   During the installation it divided the HDD into separate partitions. However every time I turn on the PC it goes directly into Windows 8.1. It doesn't allow you the opportunity to select which OS you want to use.   Question 1: How do I set the PC so it will allow me to select the OS?  Question 2: And if #1 isn't possible. How to I remove Ubuntu from the PC and recover the partition for Windows Compute $E(X\mid X+Y)$ for independent random variables $X$ and $Y$ with standard exponential distributions For each positive even integer $n$, set   $$P_n = \displaystyle {{n} \choose {\frac{n}{2}}}\frac{1}{2^n}.$$  Show that $\displaystyle \lim_{n \to \infty} P_n$ exists and determine its value.   Here's what I have so far: each $P_n$ can be thought of as the probability of tossing a fair coin $n$ times, and obtaining exactly $\frac{n}{2}$ heads. My expectation is that $P_n \to 1$, since in any large trial, one would expect to record just about as many heads as tails. But I'm not sure how to mathematically justify this hunch.  Hints or solutions are greatly appreciated. Finite Sum of Power? Smooth shaded model has odd shading I'm currently working on a model of an X-wing that I'm intending for use in a game and running into a bit of trouble with the shading of the mesh. The upper nose is rounded off where the sensor cone attaches, but at the point it reaches the canopy frame it flattens out and meets at a corner.  Everything is fine and dandy when the sides are modeled:    but once I close it off and add the top of the nose, the shading goes to hell:    As you can see, the smoothing gets confused at the lip of the cockpit.  I've tried a couple different means of getting around this, none of which looks right while maintaining the correct shape. The transition from the rounded to flat is a fairly important part of the ship's character, so I don't want to discard the contours, either.  Any tips or suggestions on modeling this area?  Addendum:  If I eliminate that second angle where the canopy frame meets the fuselage as marked in red:    this also fixes the smoothing. However this is not a solution, as the angle is a part of the design. It DOES give me another thought on fixing, but I won't be able to test it until I get home. If $I_n=\int _0^{\pi }\sin^{2n}\theta \:d\theta $, show that $I_n=\frac{\left(2n-1\right)}{2n}I_{n-1}$, and hence $I_n=\frac{\left(2n\right)!}{\left(2^nn!\right)2}\pi $  Hence calculate $\int _0^{\pi }\:\sin^4t\cos^6t\:dt$  I knew how to prove that $I_n=\frac{\left(2n-1\right)}{2n}I_{n-1}$, but I am not very good at English, what does it mean Hence $I_n=\frac{\left(2n\right)!}{\left(2^nn!\right)2}\pi $ do we need to prove this part as well or is it just a hint to use? and for the other calculation to find $\int _0^{\pi }\:\sin^4t\cos^6t\:dt$ is there something in the first part that I can do to help me solve this question because otherwise it becomes very long and it's part of the question. Automatic coloring of numbers according to size Scientific talks have their own culture, reporting the results, typically for me, in a table of the following form  1.7333    1.6472    1.5418    1.4682    1.5740 1.1525    1.2878    1.2652    1.3511    1.5102 1.2181    1.1500    1.2220    1.2425    1.5699 0.9786    1.1051    1.1472    1.3096    1.6757 0.9569    0.9190    1.0433    1.2924    1.4867   There is clearly a(n almost perfectly) monotonic pattern for rows and columns. Now for the naked eye, this is not the most quick way of capturing informing.  I would like numbers that bigger in absolute value, to appear differently (either green vs red or light vs dark) than smaller numbers, such that the pattern becomes clear instantly.  Is there a way of programming this in LaTeX? How to find the square root of a permutation Observe that  $$\begin{pmatrix} 1 &amp; 2 &amp; 3 &amp; 4 &amp; 5 \\  2 &amp; 4 &amp; 1 &amp; 5 &amp; 3 \end{pmatrix} \begin{pmatrix} 1 &amp; 2 &amp; 3 &amp; 4 &amp; 5 \\  2 &amp; 4 &amp; 1 &amp; 5 &amp; 3 \end{pmatrix} =  \begin{pmatrix} 1 &amp; 2 &amp; 3 &amp; 4 &amp; 5 \\  4 &amp; 5 &amp; 2 &amp; 3 &amp; 1 \end{pmatrix},$$  so $\begin{pmatrix} 1 &amp; 2 &amp; 3 &amp; 4 &amp; 5 \\  4 &amp; 5 &amp; 2 &amp; 3 &amp; 1 \end{pmatrix}$ is the square of a permutation. More generally, how do I check if a permutation is square and how can I find its root? Word for something sad and funny at the same time After logging in on terminal with user name and password, how do I start the GUI? I am new to Ubuntu, and I am working on a Mac. The Ubuntu installation was done by someone else. I logged in with the user name and password, but I'm not sure what next to do in the terminal to get to the graphical interface. Could someone assist or point me in a direction where I can get useful guidelines? I have done research, but nothing I found helped me.   When I tried to start the lightdm greeter, I got the following message:  lightdm.service not found     Update: My understanding is that Ubuntu Server is installed. I'm trying to migrate a MySQL-based app over to Microsoft SQL Server 2005 (not by choice, but that's life).  In the original app, we used almost entirely ANSI-SQL compliant statements, with one significant exception -- we used MySQL's group_concat function fairly frequently.  group_concat, by the way, does this: given a table of, say, employee names and projects...  SELECT empName, projID FROM project_members;   returns:  ANDY   |  A100 ANDY   |  B391 ANDY   |  X010 TOM    |  A100 TOM    |  A510   ... and here's what you get with group_concat:  SELECT      empName, group_concat(projID SEPARATOR ' / ')  FROM      project_members  GROUP BY      empName;   returns:  ANDY   |  A100 / B391 / X010 TOM    |  A100 / A510   So what I'd like to know is: Is it possible to write, say, a user-defined function in SQL Server which emulates the functionality of group_concat?   I have almost no experience using UDFs, stored procedures, or anything like that, just straight-up SQL, so please err on the side of too much explanation :) Most OO languages prefix their interface names with a capital I, why does Java not do this?  What was the rationale for not following this convention?  To demonstrate what I mean, if I wanted to have a User interface and a User implementation I'd have two choices in Java:        Class = User, Interface = UserInterface   Class = UserImpl, Interface = User      Where in most languages:     Class = User, Interface = IUser   Now, you might argue that you could always pick a most descriptive name for the user implementation and the problem goes away, but Java's pushing a POJO approach to things and   most IOC containers use DynamicProxies extensively.  These two things together mean that you'll have lots of interfaces with a single POJO implementation.  So, I guess my question boils down to: "Is it worth following the broader Interface naming convention especially in light of where Java Frameworks seem to be heading?" Workflow for developing add-on/script I'm trying to figure out a good workflow for developing scripts and add-ons in Blender. Here's what I'm currently doing as I try my luck with a PyNode add-on:   Open blender Create a text editor panel Open my script (external text file) Edit my script in a nice external editor Reload the script Save the .blend file Run the script   Now that I can see what my code does, this Blender instance has been modified, so I can't (make changes to my script and) run my script again. So I do this:   Close blender Open blender with the .blend from step 6 and repeat steps 4-7, over and over and over..   Is there a better workflow for this sort of thing? In Blender 2.8, how do I light an EEVEE scene with an HDR?
