Opening Chromium on Ubuntu VPS Ubuntu noob here. I recently got a VPS running Ubuntu, and decided to install Chromium, my preferred browser, on it. After installation completed, I got a message stating that I cannot open Chromium with root privileges. How would I go about opening Chromium? How to interpret busybox "top" output? I am using BusyBox on a small embedded ARM system.  I'm trying to read the "top" output, in particular for the Python process listed.  How much real memory is this process using?  Also what does VSZ stand for?  The system only has 64MB of RAM.   Mem: 41444K used, 20572K free, 0K shrd, 0K buff, 18728K cached CPU:   3% usr   3% sys   0% nic  92% idle   0% io   0% irq   0% sirq Load average: 0.00 0.04 0.05 1/112 31667   PID  PPID USER     STAT   VSZ %VSZ %CPU COMMAND   777   775 python   S     146m 241%   3% /usr/bin/python -u -- dpdsrv.py "Bring" vs. "take" in American English Does anyone know of a .NET date/time parser similar to  (handles stuff like "tomorrow" or "3pm next thursday")?  Note: I do write Ruby (which is how I know about Chronic) but this project must use .NET. I'm trying to include a file with a specific shape (cup) into another TikZ image, in order to use the cup as a "stamp" to draw more complex figure. The file is located in /usr/share/tikzit/shapes/cap.tikz  \documentclass{article} \usepackage[svgnames]{xcolor} \usepackage{tikz} \usetikzlibrary{decorations.markings} \usetikzlibrary{shapes.geometric} \pagestyle{empty}  \pgfdeclarelayer{edgelayer} \pgfdeclarelayer{nodelayer} \pgfsetlayers{edgelayer,nodelayer,main}  \tikzstyle{none}=[inner sep=0pt] \tikzstyle{node1}=[cap,fill=White,draw=Black]  \tikzstyle{simple}=[-,draw=Black,line width=2.000] \tikzstyle{arrow}=[-,draw=Black,postaction={decorate},decoration={markings,mark=at position .5 with {\arrow{&gt;}}},line width=2.000] \tikzstyle{tick}=[-,draw=Black,postaction={decorate},decoration={markings,mark=at position .5 with {\draw (0,-0.1) -- (0,0.1);}},line width=2.000]  \usepackage[graphics,tightpage,active]{preview} \PreviewEnvironment{tikzpicture} \newlength{\imagewidth} \newlength{\imagescale}  \begin{document} \begin{tikzpicture}     \begin{pgfonlayer}{nodelayer}         \node [style=node1] (0) at (-2.5, 1.5) {};     \end{pgfonlayer} \end{tikzpicture}  \end{document}   The code i want to include is the following:  \begin{tikzpicture}         \path [use as bounding box] (-2,-2) rectangle (2,2);         \begin{pgfonlayer}{nodelayer}                 \node [style=none] (0) at (0, 0.75) {};                 \node [style=none] (1) at (-0.5, 0) {};                 \node [style=none] (2) at (0.5, 0) {};         \end{pgfonlayer}         \begin{pgfonlayer}{edgelayer}                 \draw [in=0, out=90] (2.center) to (0.center);                 \draw [in=270, out=-90, looseness=0.75] (1.center) to (2.center);                 \draw [in=90, out=180] (0.center) to (1.center);         \end{pgfonlayer} \end{tikzpicture}   But it seems I miss how to specify the directory of cup. I get this error:     Package pgfkeys Error: The key '/tikz/cap' requires a value. I am   going to ignore this key.   It seems like I have to deal with tikzstyle or pgfkey, but I don't know how to specify an external file. Is there exist a function defined on the real or complex numbers that, restricted to the integers, is equal to the factorial? According to the Wikipedia article on  the sample SD   $$s = \sqrt{\frac{1}{n-1} \sum_{i=1}^n (x_i - \overline{x})^2}$$  is a biased estimator of the SD of the population. It states that $E(\sqrt{s^2}) \neq \sqrt{E(s^2)}$.   NB. Random variables are independent and each $x_{i} \sim N(\mu,\sigma^{2})$   My question is two-fold:   What is the proof of the biasedness? How does one compute the expectation of the sample standard deviation    My knowledge of maths/stats is only intermediate. The sentence     Women driving cars is, of course, such a foreign sight to a society like   Saudi Arabia   The subject is not "women" (otherwise, the verb would have been 'are'); the subject, as I mean to use it, is the rarity of seeing women driving cars. The subject, in other words, is "women driving cars" as a thing. Does this give me licence to use 'is' here? Thank you. Let $p$ be a prime number. If -1 is a square in $\mathbf F_p$, it means that there exists an element of order 4. So $p-1$ is divisible by 4 and therefore $p \equiv 1$ (mod 4). I wonder the converse is also true. Does $p \equiv 1$ (mod 4) mean the existence of an element whose square is $-1$ in $\mathbf F_p$? Lets assume my classes are loaded from a compressed .war file or loaded elsewhere,  how can I discover all the resources in a given package?  Enumerating files will not really work, since this is a war file.  Most likely this will involve using the current classloader?  Is there a library out there that does something like that? Googling revealed only some hacks with listing files. How to change plot style or other options after it was created What dried food can I take across the American border from Canada? We will be driving from Banff to Glacier National Park while on our camping trip and I was told to be careful with taking food across the border. We don't eat meat so that's one less issue and I already know that many fresh fruits/veggies can get complicated so I'm only thinking of taking dry stuff across (mostly grains but possibly also dried veggies).  My plan at first was to stock up at BulkBarn in Calgary since they have tons of stuff and you can just take what you need but I'm afraid that since the packaging is generic and unsealed that it might cause more problems. What are the criteria to be able to take dried food across the border? Usage of singular or plural SI base units when written in both symbol as well as name I have multiple doubts related to the usage of singular or plural SI base units when written in both symbol as well as name.  I have framed this question under two parts, namely, Part (a) and Part (b). Each part has three sentences which I have written on the basis of my understanding.  Please answer these 6 sentences/questions.   Part (a):   says that while using prefix for e.g., centi as in centimeter, it is   l = 75 cm long.(correct) l = 75 cms long. (wrong)    Does this rule is used for all SI prefixes (having powers of 10)? In this regard, we should be saying, or writing that, "how many cm are there in one metre?" (while saying we should say centimter or centimetres?) Please strike-through the wrong SI unit in the following sentences.  My weight is 70 kg / kgs,  or My weight is 70 kilogram / kilograms.   Part (b):  and the page next to above web link says, we should write:  2.6 m/s, or 2.6 metres per second.   In this regard, we should say, or write:   Its speed is 0.26 metres per second.  This pipe is 0.75 metres long. How many cm are there in 2 metres? SQL - Stored Procedure with Select Statement using IN (@Variable_CommaDelimitedListOfIDS) How come I can't give more than 500 rep? Why can't I give more than 500 reputation as a bounty at a time? The system won't let me choose an option more than 500.  Also, how were some users able to do so? On  the OP has given a single bounty worth 550 rep, but at the moment I have 844 rep and I can't give any more than 500 rep on a bounty.  Can you please tell us if this is a bug or not? Finding the maximum likelihood estimator (Theoretical statistics) Let $X_1, X_2, ..X_n$ represent a random sample from this pdf:  $$f(x|\theta)= \frac{3x^2}{\theta^3}, 0\leq x\leq \theta$$ (with 0 elsewhere)  Could someone explain how I would find the maximum likelihood estimator (MLE) of this pdf? I know I have to get the likelihood function L, then the log likelihood function, then differentiate, but I am getting lost in the calculations. Thanks! Indentation in tcolorbox package I'd like to have the same indentation within a tcolorbox as I have in the rest of the document.  How can I get it?  Thanks.  MWE:  \documentclass[a4paper]{book}  \usepackage{lipsum} \usepackage[most]{tcolorbox}  \begin{document}  \chapter{Example with \texttt{tcolorbox}} \lipsum[1-8]  \begin{tcolorbox}[breakable,enhanced] \lipsum[9-14] \end{tcolorbox}  \end{document}   The first block of text has the typical indentation, but that in the box doesn't. TV identification: Short-lived TV show about a time traveller with a super-computer disguised as a credit-card It might have only been a pilot or a made for TV movie, but I remember a male time traveller who was for some reason in 90s US from a semi-distant future. He had in his possession a super-computer disguised as a regular credit card, which could hack things and I think spoke to him in a female voice.   Note: Not Quantum Leap - the time traveller and "credit card computer" might be keywords that people would hit upon, but 'Ziggy' the computer in QL was non-speaking, operated by a hologram and did not resemble a credit card - this one had its own voice and was disguised as a CC. zeros of a polynomial Given $P(z)=z^6+6z+10$, find how many roots are in each quadrant    I have already seen that $P(z)$ has six different roots, and that none of them are real or of the form $ki$, $k\in \Bbb R$. Since the coefficients of $P(z)$ are real, then it's roots are 3 conjugate pairs, and therefore the possibilities are limited to two.  Defining $f(z)=z^6$, $g(z)=z^6+6z+10$ and applying Rouche in $|z|&lt;2$, $|f(z)-g(z)|&lt;|f(z)|$ I get that all roots are contained in the disc, but how do I go about splitting them into the four quadrants? From what I know about this polynomial, finding zeros in one quadrant is enough to determine the rest, but I'm stuck trying to apply rouche to a quarter circle (basically I'm having trouble finding a suitable f and g) I have downloaded and extracted the packet tracer file, then I used this command as root  chmod +x install   then I ran (as root)  ./install    Then I used this command   ./set_ptenv.sh   but whenever I run this command   packettracer    it just doesn't start
