How can I change the names of items in the EFI/UEFI boot menu? I use Ubuntu 18.04 on my computer. This Ubuntu installation appears as ubuntu at system EFI boot menus.  I also have a external USB storage that has a EFI Ubuntu installation. This external USB storage also appears with the name ubuntu at system EFI.  I see two ubuntu menus at system EFI boot menus when external USB storage is attached. This makes it hard to figure out which ubuntu menu item points to the Ubuntu installation on the computer, and which one points to the Ubuntu installation on the external USB storage.  How I can change the EFI boot label to something different?  For example, how can I change ubuntu EFI boot label on the external USB storage to appear as External Ubuntu at system EFI boot menus?   The Ubuntu on my external USB storage has its own EFI partition.  This question is different from   This question is about how to change the Efi Boot name that appears in the EFI Firmware setup and not in the GRUB boot menu.
How to safely change OS name in grub boot menu? I have a system where I am dual-booting Ubuntu GNOME 15.10 and Ubuntu GNOME 16.04, however after installing Ubuntu GNOME 16.04, I have found that in the GRUB boot entry list it is called "Ubuntu", whereas the other one is called something like "Ubuntu GNOME 15.10", is there any way I can change the text of the "Ubuntu" one to "Ubuntu GNOME 16.04"? And also change the names of the other options so that instead of "Advanced options for Ubuntu" it says "Advanced options for Ubuntu GNOME 16.04" etc?  I rather do it manually if it is safe to do so, or a piece of software could be recommended, however nothing from a PPA or other untrusted not official source (I will only install software from the Ubuntu official repositories).
Qualitative variable coding in regression leads to "singularities" declare property as object? Prove that every number ending in a $3$ has a multiple which consists only of ones. Prove that every number ending in a $3$ has a multiple which consists only of ones.      Eg. $3$ has $111$, $13$ has $111111$.   Also, is their any direct way (without repetitive multiplication and checking) of obtaining such  multiple of any given number( ending with $3$) ? A new environment based on enumerate I have defined the following simple environment:  \newenvironment{renumerate}{\begin{enumerate}\raggedright}{\end{enumerate}}   I wonder how the above can be modified to use with, say, the following:  \begin{renumerate}[label=\color{blue}10.\theenumi] \item blah \item blah \end{renumerate}   The options given in [] are not known in advance. Is this a grammatically correct line in a poem: “Will he roll the dice, and follow it to Vegas?”? I want to use the following line in a poem: "Will he roll the dice, and follow it to Vegas?"   A couple of things to note; firstly, obviously I'm using "roll the dice" in both a figurative/idiomatic sense (as in taking a risk), and in a somewhat more literal sense (painting the image of the person actually following the dice that have been rolled to Las Vegas). That being said, my confusion here is if I can get away with using "follow it" or if I need to say "follow them" .... As I've read online "dice" traditionally refers to more than one die (i.e., the plural of die), but in the modern usage, "dice" can also be used to refer to the singular (i.e., just one die).   So, it seems like if I was referring to the image of just one die, then the way I phrased it could be correct. However, the image I'm trying to paint is the one usually associated with the phrase "roll the dice" (i.e., rolling two dice)...   So could "follow it" still be considered acceptable in this sense... or would I need to use "follow them"?... And if not referring to the dice themselves, could using, could the "it" be taken to refer to the act of rolling the dice, or would that not work either? Thanks so much in advance!! How does vampirism work? A PC in our group was off on his own following a recurring villain of our groups. He was paralyzed where he could move, and the vampire bit his neck. The vampire said "now you get to remain 19 (years old) forever" before he left the cave. This was all done in RP.  We found him later, and healed up his bite marks. Our characters know of vampires, specifically only the one that bit him (recurring villain), but don't really know how vampirism works, because it isn't a super common thing in this world yet.   My question as the player is:  How does RAW vampirism work in 5e?  Is it a disease that develops over time? Is it something where they have to die and be brought back as a vampire?

(Fibonacci puzzle) There is a very interesting puzzle for Fibonacci sequence:     You are climbing a stair case. It takes n steps to reach to the top. Each time you can either climb $1$ or $2$ steps. In how many distinct ways can you climb to the top?   The answer is Fibonacci sequence: $F(n) = F(n - 1) + F(n - 2)$. The explanation is that you could reach the $n$th step either from the $(n - 1)$th step or $(n - 2)$th step.  What I fail to understand is why isn't the answer $F(n) = (F(n - 1) + 1) + (F(n - 2) + 2)$. Since, after reaching $(n - 1)$th step I have to take $1$ step to reach the $n$th step and after reaching $(n - 2)$th step I have to take another $2$ steps to reach the $n$th step.  I know I might be ignoring some very stupid detail but it's better to ask and be called a fool once than to remain a fool forever. Math mode in tabular without having to use $...$ everywhere Is there a string math evaluator in .NET?
