It's been confirmed in official Star Trek canon that various races across the Federation can copulate together. These include, to name a few, Earth and non-terrestrial humans, Khardasians, Trill hosts, Jem Hadare, the Ocampan, Romuluns, Vulcans, and Klingons. Other races, like the Ferengi, can mate with other humanoids, but it's unconfirmed if they  produce offspring there with. Matings that result in progeny often produce hybrids that combine traits of both species. Most such pairings are with a human and another species. Some famous examples of these characters are:  B'Elanna Torres (Voyager, half-human, half-Klingon) Commander Tuvok (half-human, half-Vulcan) Deanna Troi (TNG, half-human, half-Betazoid) Sela (Romulan-human hybrid), Alexander Roshenko (Klingon, 1/4 human on his mother's side) and of course, Mr. Spock (TOS, part human and part Vulcan).  It's noticeably rare, however, that we see a depiction of a dual alien mixture. One I was most intrigued by, was the concept of a half-Vulcan, half-Klingon child. Due to how drastically different the races are, it's statistically unlikely that we'll see one on screen, but the possibility still exists. Besides that, Star Trek has a very long-standing, detailed and massively expansive universe in books and comics. So... Has there ever been an official, canon or at least extended universe Vulcan-Klingon hybrid character in the Star Trek franchise? If so, who is the character, how were they raised and what do they look like?
Hybrids are fairly common in Star Trek:  is half Vulcan,  is half Betazoid,  is half Klingon and, just for good measure,  is ¼ Romulan.  However, in all of these cases that I can think of, the other half is always human.  Are there any non-human hybrid characters? Especially ones that are recurring or at least the focus of an episode?  If not, is there an out-of-universe explanation for their absence/rarity/scarcity? From a fandom point of view, I can’t imagine a half-Klingon half-Vulcan might not make for an interesting story, for example.
Filling cells with sequential numbers in an Excel (2003) macro I need to fill an excel column with a sequential series, in this case from -500 to 1000.  I've got a macro to do it, but it takes a lot of lines for something that seems like it should be a single function [something like FillRange(A2:A1502, -500, 1000, 1)].  But if that function exists, I can't find it.  Is the following as simple and elegant as it gets?

All questions related to 138a:0018 are either unanswered or old. Any help guys? What is the difference between Θ(n) and O(n)? For $a, b \geq 0$, $0 < x < 1$, show $(a+b)^x \leq a^x + b^x$ Let $a, b$ be positive real numbers. Let $0 &lt; x &lt; 1$. Show that  $(a+b)^x &lt; a^x + b^x$.  The function $f(x) = (a+b)^x -a^x - b^x$ has $f(0) = -1$, $f(1) = 0$ and it seems to be an increasing function. But I am unable to show that it is increasing function. Poisson Distribution of sum of two random independent variables $X$, $Y$ $X \sim \mathcal{P}( \lambda) $ and $Y \sim \mathcal{P}( \mu)$ meaning that $X$ and $Y$ are Poisson distributions.

How to find a starting point for root finding in complex plane? The function $f(x) = x^2 +1$ has zeros in the complex plane at $x = +i$ and $x = -i$. Is there a real starting point for complex Newton's method such that the iterates converge to either of these zeros? Is there a complex starting point too?  I know that Newton's method for finding roots is $x_{n+1} = x_n - \frac {f(x)}{f'(x)}$. But I don't know how to find the proper starting point.

Will moving blog posts from under an existing category to a new SUBcategory have a negative impact from an SEO POV? I've got a 32-bit Ubuntu installation running on 64-bit hardware. Now that , I would like to switch to 64-bit without having to reinstall the OS.  This is one of the :  Shawn installed his system using the 32-bit version of Ubuntu, but his hardware is 64-bit and he wants to switch over. He manually installs the amd64 versions of dpkg and apt, replacing the i386 versions and changing which architecture is used as the default; then he installs the amd64 ubuntu-minimal package; then he installs the amd64 ubuntu-desktop package. Over time the remaining i386 packages are replaced automatically on upgrade.  However, when trying to follow the instructions in there, I cannot find any 64-bit version of dpkg or apt.  Did this user story got implemented in a different way in the final spec, or do I need to do something differently?  In short, how can I switch my 32-bit installation to 64-bit? I was able to install Ubuntu 12.04 using the alternative version of the image, (64 bit) but when I start the system it tells me the GPU  locked up, and instead presents a text only screen.  I understand that this site is not for bug reports, but at the same time, I know that there are some versions of the installer than have to be compatible with my graphics card (Nvidia GTS 360M).  I assumed that the mere fact that the alternative installer ran was an indication that I could get some sort of graphical interface running after the install.  Is there some way of getting some type of graphical interface running on my machine? Even better would be is there a way to get the rest of the system running as normal (i.e. GPU up and running)?  If an internet connection is required to download driver support or something similar, directions for how to configure a wireless connection with WPA2-Personal protection from the text-only interface (bash).  Any help would be appreciated.  Note: I was able to find  which tells me that the card is supported.  Note 2: In the install software stage of the install, I was unable to install anything (no internet connection)  Update: The exact error message is [8.591394] [drm] 0000:01:00.0: GPU Lockup - switching to software fbcon  Update 2: If I try to install with the regular version of Ubuntu, the screen goes staticy. This also happens if I install with Wubi (distasteful I know) and then try to use Ubuntu.  Update 3: I've tried xforcevesa, nomodeset and xforcevesa nomodeset as my wubi boot options.  Update 4: Thanks to jokerdino, I can now connect to the internet, so internet tools would now be a possibility.
