I need to write a tex file in french. But in this tex file, there will be also many characters in greek and I want to use a personal font for these ones. How could I do ?
I want to include some Cyrillic with a TeX Gyre Pagella text and math font document. I'm using TeXLive 2019.  As indicated in , running pdflatex on the following source works just fine:  \documentclass{article}  \usepackage[T1,T2A]{fontenc} \usepackage[russian,main=english]{babel} \usepackage{paratype} \usepackage{tgpagella} \usepackage{substitutefont} \substitutefont{T2A}{\rmdefault}{PTSerif-TLF}  \usepackage{amsmath}  \usepackage[math]{blindtext}  \begin{document}  The topologist is {\Russian Алекс\'{а}ндров}.  \blindmathpaper  \end{document}   However, running xelatex on the following surce produces output from which the indicated Cyrillic just disappears:  \documentclass{article}  \usepackage[T2A,T1]{fontenc} \usepackage[russian,main=english]{babel} \usepackage{amsmath} % load here to avoid \dddot clash \usepackage{fontspec} \usepackage{paratype} \setmainfont[Ligatures=TeX]{TeX Gyre Pagella} \usepackage{substitutefont}% \substitutefont{T2A}{\rmdefault}{PTSerif-TLF}%  \usepackage{unicode-math} \setmathfont{TeX Gyre Pagella Math}  \usepackage[math]{blindtext}  \begin{document}  The topologist is {\Russian Алекс\'{а}ндров}.  \blindmathpaper  \end{document}   Question: How should this second source be fixed so as to allow the Cyrillic to appear, too?  (I did put Map paratype-truetype.map into my local updmap.cfg file and did run updmap-user.)
I am trying to display certain features in a shapefile-based layer using QGIS. I have found the subset function in the properties panel, which does exactly what i want, but is too tedious given that I have to manually sift through a large number of features. Is there a quicker way to do this?  I am using both shapefiles and postGIS best,  dietmar Is it possible to unwrap materials made in Vertex Paint? I painted an group of objects in Blender using the Vertex Paint and was wondering if it would be possible to unwrap the mutliple materials(when the objects are joined together using Ctrl+J)? Do I have to paint it all over again? I want to learn Linux Kernel and I've downloaded the latest kernel version.

Variance of the future value of a cash flow I want to compute the variance of $FV =A\sum_{k=1}^n(1+r)^k=:g(r)$, assuming interest rate $r\sim\mathrm{N}(\mu,\sigma^2)$ and constant equal payments $A$. As discussed in the comments, the Delta Method gives an approximation $\mathrm{Var}[FV]≈\sigma^2\times(g′(\mu))^2$. Is there a way to get an exact answer? I need to do a polynomial interpolation of a set $N$ of experimental points; the functional form I have to use to interpolate is this:  $$ f(x) = a + bx^2 + cx^4,$$ as you can see the coefficient that I need to find are just 3: $a, b, c$; however the points I have are $\#N&gt;3$ and so it looks like the determination of the coefficients is impossible because is over-determined. Does anyone have an idea of what should be done in such case (supposing it is even possible)? What is the purpose of .bashrc and how does it work? Applying Zorn's Lemma to natural numbers Zorn's Lemma states that if every chain $C$ in a partially ordered set $X$ has an upper bound then there is at least one maximal element in $X$.  Let $n\in \mathbb{N}$, $C_n \subset \mathbb{N}$ be the set containing the natural numbers $\{1,\dots,n\}$. Then if $k\le n$, $C_k\subset C_n$, so $C_n$ is a chain. Also, $C_n$ has an upper bound, such as $n+1$. But what is the maximal element of $\mathbb{N}$?  There's something I don't get in Zorn's Lemma statement. I want that my monitor turns off when I am inactive for a while, but I do not want that I am prompted for a password when I revoke my pc. In Ubuntu 16.04 it was possible to disable the lock but still enable the screensaver as explained .  In Ubuntu 18.04 I entered the following in terminal:  dconf-editor   and disabled ubuntu-lock-on-suspend:    However, since I made this change, my monitor never suspends anymore. I tried restart but it didn't help.  Any ideas how I can disable lock but still enable suspend mode?

At the moment I am using a Nikon D3100 with the standard kit lens (18-55mm). I am interested in taking photos of the moon. I am debating whether to buy a 55-200mm lens or a 55-300mm lens. Which one would be better?  P.S I am on a tight budget and I am looking for a lens for personal use, not commercial.  Would appreciate any answers!  Thank you! Is it possible to have the Corruption and the Crimson Biomes in the same world? I was reading on the wiki how there is a chance that the Corruption will be replaced with the Crimson.  I am wondering if when you get a world where you have the Crimson is it possible to also have the Corruption if you bring over corruption seeds from another world and use them. Or would these seeds just get you more of the Crimson? How can I manually create a pixel perfect image sprite? How to re-enable tray icons for applications in Ubuntu? Probability that the bag contains all balls white given that two balls are white A bag contains $4$ balls .Two balls are drawn at random and are found to be white.  What is the probability that all the four balls in the bag are white?.  The options are $\large\frac{1}{5}\space ;\frac{2}{5} ;\frac{3}{5} ;\frac{4}{5}$  My work: It's given that two balls are white.So the rest of the balls could be    all white One of them white none of them white   So among the three above possibilities only one satisfies our conditions so the probability is $\frac{1}{3}$.But it not even the options given. What's wrong with my work?
