Can I run Fallout : New Vegas without a video card? I was looking at my laptop's specifications ( an Hp probook ) and it doesn't have a video card. Can I still get and run Fallout : New Vegas? Not the ultimate edition.
How can I check if my computer's powerful enough to run a certain game? Is there a service that I can use to check if my machine will be able to run a certain game?
Children's fantasy series with a symbol consisting of a circle divided into quarters I read this book series as a kid back in the late 1970s, so it's an old series - and my memories are similarly old, and vague.   I know it's a fantasy series. I think there are 4 books in the series. Or perhaps 7.  There's a central boy character who has to get a collection of magical objects (every fantasy needs a quest!), each of which represents a different magical 'element': wood, stone, fire, etc. I definitely remember there was a wooden object. He lives in our normal world. The whole series takes place "here &amp; now". I have a feeling he's a "chosen" person of some kind... But, the strongest memory I have is of a symbol: a circle which is divided into quarters (a vertical bar and a horizontal bar).  I know it's vague, but does anyone recognise this? URL of cited web site in bibliography I am using natbib with the chicago style as bibliography style. I am trying to cite a web site, but in the bibliography the URL (given in the BibTeX entry) is not printed.   Is there a simple solution to this matter? What am I doing wrong?  ok, as a little example (the entries are generated via Mendeley)  @misc{Carlson2011,    author = {Carlson, Nicholas},   booktitle = {Businessinsider.com},   title = {{How Many Users Does Twitter REALLY  Have?}},   url = {www.businessinsider.com/chart-of-the-day-how-many-users-does-twitter-really-have-2011-31/3},   year = {2011} }   and the output in chicago-style looks like this:     Carlson, N. (2011). How Many Users Does Twitter REALLY Have? Prove: The positive integers cannot be partitioned into arithmetic sequences (using Complex Analysis) Does the output bypass capacitor of an LM7805 double as a decoupling capacitor? I'm using a 5v linear regulator (specifically an LM7805) that outputs directly to an ATMEGA328P. According to the  (page 23) input and output bypass capacitors should be used, as seen below, to tame peaks and ensure stability.    It is good practice to also include a decoupling capacitor in front of an IC, in this case an ATMEGA328. Does the 0.1μF capacitor on the output side of the LM7805 act as a decoupling capacitor if the regulator feeds into the IC directly after the output bypass capacitor? How do I adjust the Clock Indicator format? I have parent folder "parent". Inside this folder I have subfolders, and a file named "names.txt". this file includes the names of these subfolders as follow:  Parent_folder folder1 folder2 folder3 folder4 . . . . names.txt   The content of the file "names.txt" is as follow:  folder1 folder2 folder3 folder4 . . .   Inside every folder I have images and I want to apply consecutively 10 scripts on every image ( every script must finish it is job inside every folder, then the second script must be run). These scripts have different names and they are exist in one folder. I set an environment by sourcing a file then I can call these scripts by its name from terminal .At the same time I want to apply this process on all the folders at once. i.e. when script #1 is running, I want it to be running on all the folders at the same time. When it is done and script #2 will start. I want it to start in all the folders at once and so on... In order to achieve this I wrote the following code:  #!/bin/bash path=PATH/TO/THE/PARENT/FOLDER for i in $(cat $path/names.txt); do { script#1 } &amp; { script#2 } &amp; . . .  done   This code is not working efficiently as all the commands are running at once. I want the commands to run on all the folders at once but consecutively.  What I am doing wrong? How to change password complexity requirements in Ubuntu 14.04LTS I have a Godox X2Tc and a Godox X1Rc. I want to control my Canon Speedlite 430 EXII. (I also have a Godox V1, which is a beautiful thing!) I have the Canon Speedlite attached to the Godox receiver, so it should fire. It just wont! How do I set it up correctly so the receiver makes the Canon Speedlite fire?  Update: Michael C answered this question. I had the ID numbers set differently on the transmitter and receiver. I made them the same and now it all works. Perfect! Thanks Michael!! Data   I want operator users on this machine to mount their own cifs shares The sudoers file already contains the /bin/mount -t cifs //*/* /media/* -o username=* command for all operators I want the users to mount a cifs share through a script typing the password only once, not twice. The sudo password and the cifs password are identical.   What I already have  This script works:  #!/bin/bash sudo 'mount -t cifs //192.168.1.1/home /media/$USER/home -o username=$USER'   ...but it requires the users to type the same password twice!     Once for sudo Once for the mount itself   This would also work:  #!/bin/bash echo -n Password:  read -s szPassword echo $szPassword | sudo -S sh -c 'echo $szPassword | mount -t cifs //192.168.1.1/home /media/$USER/home -o username=$USER'   ...but this would require me to allow all operator users to be able to sudo sh (major security problem)  Question  How to mount a cifs share in bash¹ without putting sh in the sudoers file nor creating a permanent/temporary file???  Note 1: no python, perl, C, Go, ... please? Note 2: I know I can just remove the password through the sudoers file, but I'm trying to tighten security, not loosen it, without giving up convenience... Should the eigenkets be weighted in $|P\rangle = \sum\limits_{r}|\xi^r\rangle$? Page 37 of Dirac's book The Principles of Quantum Mechanics, states  The condition for the eigenstates of $\xi$ to form a complete set must thus be formulated, that any ket $|P\rangle$ can be expressed as an integral plus a sum of eigenkets of $\xi$, i.e. $$|P\rangle = \int |\xi'c\rangle\; d\xi' + \sum\limits_{r}|\xi^rd\rangle$$ where the $|\xi'c\rangle$, $|\xi^rd\rangle$ are all eigenkets of $\xi$, the labels c and d being inserted to distinguish them when the eigenvalues $\xi'$ and $\xi^r$ are equal, and where the integral is taken over the whole range of eigenvalues and the sum is taken over any selection of them.  I find it inconsistent that the eigenkets under the integral are weighted by what appears to be a differential eigenvalue $d\xi'$, yet all the eigenkets under the summation are weighted by the value 1. Is this correct? Formatting section titles Forgive the stupid simplicity of this question, and please feel free to refer me to an older answer. I'm not quite familiar enough with LaTeX terminology to have found it.  All I want to do is set a different default format for my section titles. Instead of just being bolded and slightly larger than the main text, I'd like them to be of normal weight, the same size as the main text, and all caps.   I'm using the article class. Let $R$ be a Artinian commutative ring with $1 \neq 0$. If $I$ is prime, then $I$ is maximal. Prove: Let $R$ a Artinian commutative ring with $1 \neq 0$. If $I$ is prime, then $I$ is maximal.     I got stuck on this. I understand that every ideal is generated by finitely many elements. Here is my approach:  It's enough to prove the following implication: $$ R/I \ \text{is a domain} \quad \Rightarrow \quad R/I \ \text{is a field}$$ Then only finding an inverse is left. So let $x \in R$ in arbitrary. We have to find an inverse element of $x+I \in R/I$, that as an element y so that $x \cdot y \in I+1$. We denote $I = (x_1, x_2, \cdots, x_n)$.  Now I have to find y so that $xy -1 = r_1 x_1+ r_2 x_2 + \cdots + r_n x_n$. This is where I no more knew what to do.   Your advise will be appreciated. Complicated FOR loop nesting. Having trouble cleaning up legacy code I would be happy to get some hints on the following integral: $$ \int_0^1\frac{x^{19}-1}{\ln x}\,dx $$ If $F\supset E$ and $E\supset k$ are normal extensions. I want a counter-example where $F\supset k$ is not normal Java Interface Usage Guidelines -- Are getters and setters in an interface bad? I've installed the GNOME Shell in Ubuntu 12.04 and I want to change the "Shell Theme", But it doesn't allow me to do that.  The alert says something like: "The GNOME-Shell extension is not activated", and I want to install it with the console, But it returns me an error.  How can I solve this problem? Can I boot memtest86+ if I'm using UEFI? Downloaded the Ubuntu 16.04.2 .iso install disk and flashed it onto a USB stick.  Booting on the USB stick, there is no memtest86+ option (along with "Try Ubuntu").  Is there a way to add it to the install options?  (it's for a UEFI boot PC running normally Windows, its owner does not want to install Ubuntu. "memtest86+" is completely free (unlike "memtest86"), but is quite old, and does not offer a UEFI boot - this is why having it within the Ubuntu options makes things easier) If $p$ is congruent to $2 \pmod 3$, how can I prove that all $a$, $1 \le a \le p-1$ are cubic residues $\mod p$? If $p$ is congruent to $2 \pmod 3$, how can I prove that all $a$, $1 \le a \le p-1$ are cubic residues $\mod p$?  Here's what I've done:  $1^3$ congruent to $1 \pmod p$ thus, 1 is a cubic residue, Also $(p-1)^3=(p-1) \pmod p$ implies  $$(p-1)^3 - (p-1) = (p-1)[(p-1)^2 -1] = (p-1)(p^2 -2p) = p(p-1)(p-2) $$ implies $$p|(p-1)^3 -(p-1)$$ Thus  $p-1$ is a cubic residue $\mod p$. Now I don't know how to show for $1\lt a \lt p-1$ are all cubic residues when $p$ is congruent to $2\pmod 3$. Search in favorited questions? I wonder if it is possible to search in just my favorited questions?  If not, can it be considered as a feature request?
