In The Last Jedi would Holdo's plan have worked if not for Poe's folly?      Holdo planned to discreetly evacuate the remaining Resistance members using small transports.  It seemed to me that the reason many of them got blown out of space was because when Finn and Rose got caught that guy DJ told the enemy about the escape transports.  Somehow the bad guys didn't see them until DJ told them to look.  So the transports could have evaded the bad guys had Poe not hatched that sabotage plan.   What I'm asking is, did everyone else see it that way?  The First Order would not have seen the small transports if DJ didn't alert them about it?  Or did I miss something?  If, so, really?  Poe could disobey orders, mutiny, fail, get more than half his comrades killed and that's OK because he meant well.
(Last Jedi spoilers ahead, if you haven't seen the movie, please don't read on.)  So, fridge logic moment for me:      If Vice Admiral Holdo had told Poe Dameron about the plan to just hold on long enough to make a covert run to Krait, then Poe wouldn't have felt the need to send Finn and Rose on their little side-trip, and the code-breaker wouldn't have overheard anything nor sold them out, and the First Order would've had no reason to notice the cloaked ships.   I do understand that there's a lesson in there about following orders, even if said orders come from a pretty face in a pretty dress, but that's kind of an out-of-universe reason. What was Holdo's reasoning? Surely she knew enough about Poe to realize that treating him like a mushroom1 would not result in anything good.  1 "kept in the dark and fed shit"
Price Optimization I ran linear regression on my hotel reservation data and obtained the following model fit in R:  Sales = 170.2 + 3.6*Days_left_to_checkIn + 7.6*Revenue - 9.6*Room_Rate -7.67*cancellation_price + 4.8*Number_of_cancelled_Room -8.9*Online_reputation_of_Hotel  After this, I used the Optimize function to optimize the equation for maximum revenue (Revenue = Room_Rate* Sales)  after substituting all the values of variables I got this equation  f=-9.6*Room_Rate^2 + Room_Rate*253.56  Optimize(f, lwr=10, upr=524)  What is the next step to calculate Room_Rate to maximize the revenue (revenue = Room_Rate * Sales)? Is there any better way to optimize the function of demand? MacVim -- how to make Ctrl+A go to beginning of line, Ctrl+E to the end of the line I'm trying to switch to MacVim as my main editor, and I'm liking it so far, except for one issue:  I got really used to the Mac shortcuts control-A to go to the beginning of a line, and control-E to go to the end of a line.  However, these two don't work in MacVim (control-A does something weird -- it seems to increase the last number in a line by 1 or something, and control-E seems to scroll down the screen by one line).  Any way to make these two shortcuts go to the beginning of a line / end of a line respectively instead? Not able to see links to chat, logout, or privileges What does the (unary) * operator do in this Ruby code? How can I prove $\sqrt{2} ^{\sqrt{2}}$ is irrational? Find all solutions of the equality $y^2=x^3+23$ for integers $x,y$   I guess, that x cannot be even. because we can apply mod 4 test  say $x=2k$ then $y^2=8k^3+23\equiv3\mod(4)$   but, this is not possible, since the square of an integer is congruent to $0$ or $1$ $\mod (4)$  so $x$ is of the form $4k+3$ or $4k+1$  $x=4k+3$ is also not possible for the same reason but for the last case the test fails.  any hints ? Where did the brush size lock go for sculpt mode in 2.8??? I sadly haven't been able to answer this questions using Google. In beamer, I'd like to make the default font for the entire title page, as well as frame titles, to be the default font from the old  (example ). What packages will let me use Cyrillic characters in math mode? Note I'm not actually planning on writing any, for instance, Russian prose or even any Russian words. It's just that, on paper, I've always had the habit of denoting sets by uppercase roman letters, sets of sets by script letters and, when the need arises, sets of sets of sets by uppercase Cyrillic letters. Is there some package I can load which will allow me to typeset (in LaTeX math mode) Cyrillic letters much as I would typeset Greek letters? ie. $\Zhe$ to produce an uppercase zhe. Thanks! Video produced from images only plays in VLC but no other players How Can I View All The Reputation Gained/Lost For One Specific Question If I would like to view all of the reputation I have gained or lost due to one specific question of my own, how can this be done?  Is it possible for someone with, say, 421 rep on the site in question? I am working on vector auto-regression (VARs) and impulse response function (IRFs) estimation based on panel data with 33 individuals over 77 quarters.  How should this type of situation be analyzed?  What algorithm's exist for this purpose?  I would prefer to conduct these analyses in R, so if anyone is familiar with R code or a package designed for this purpose that they could suggest, that would be especially helpful. Schengen visa validity start date My Chinese in-laws intend to visit us in one month from now. Their visa is valid from Nov 23rd. Would it be possible for them to take the airplane on November 22nd in China and arrive in Schengen area on November 23rd?  Or does the visa already have to be valid upon departure?  In our particular case, they still need to transfer in Beijing first. The actual flight to Schengen zone effectively only departs on the 23rd so I guess that should be completely fine then? After upgrading to Firefox 57 Quantum many website have rendering issues, such as empty frames, missing text or fonts, etc. I use Kubuntu 16.04 64 bit.

Any tips on how to solve this are much appreciated Different ways to execute a shell script There are several ways to execute a script. The ones I know are: /path/to/script # using the path (absolute or relative) . script        # using the . (dot) source script   # using the `source` command  Are there any other way? What are the differences between them? Are there situations that I must use one and not another? Division algorithm for polynomials in R[x], where R is a commutative ring with unity. Is there a division algorithm for polynomials in R[x], where R is a commutative ring with unity?    All the algebra books I read mention division algorithm for polynomials in F[x], where F is a field. Since the leading coefficient of a non zero polynomial in R[x] is not necessarily invertible, I find it difficult to proceed the same way we do for polynomials in F[x].  Can I get some help?

I have an external HD which used to be my TimeMachine drive.

How do I get rid of this? Are security.ubuntu.com updates eventually merged into normal updates? Upon my observation, seems new packages will first appear in security.ubuntu.com, but if you upgrade later, they will appear in XX.archive.ubuntu.com (depends on your config),  Was that true ?
