Source:   Example:     Authors and linguists are delighted that the creators of this technology did not use an acronym for it. But why did they choose the name Bluetooth? Because it crunches data? Because it takes bytes? Forget about finding a metaphor. Bluetooth is named for the Viking King Harald Bluetooth, who ruled Denmark and Norway in the eleventh century. King Harald is famous for converting to Christianity after watching a German priest succeed with a miraculous dare.   Why the? Can't we just simply say is named for Viking King Harald Bluetooth?
I read news on the BBC (on its website) this morning. When I was reading the news I noticed the definite article the was missing in a sentence. As per my opinion, the reporter missed the article the. But I also thought that the reporter also had some point as he did not use the article there. So I just wanted to confirm so landed here to get some help on it.     On the website:      It also proclaimed the group's leader, XYZ  (name), as caliph and   "leader for Muslims everywhere".      As per my opinion it should have been:      It also proclaimed the group's leader, XYZ  (name), as the caliph and   "leader for Muslims everywhere".   Source link:
Where are the proprietary NVIDIA drivers in 16.04? The proprietary NVIDIA drivers "disappeared" with my latest update:    The option of "Proprietary drivers for devices" is correctly set under the "Ubuntu Software" tab. I have the graphics-driver PPA (ppa:graphics-drivers/ppa) correctly added to my sources.  Any ideas on how to bring the proprietary drivers back?  PS1: I need them because some of the games I play under wine don't work without them, for whatever reason.  PS2: Also, this feels like it should have a straightforward answer, but I've been looking online for a while without luck. Orbiting a specific point - Orbiting Camera How would I create a camera that with the mouse, it allows you to orbit around a specifc position, with the camera always facing that point? I would also like it to be able to always be at a constant distance from the point, and be able to orbit around it in every direction.   Any ideas? Do the electric and magnetic components of an electromagnetic wave really generate each other? Frequently when EM waves are taught, it is said that the change in electric field causes a change in the magnetic field, which then causes a change in the electric field, and so on and so forth.   But from my understanding of basic electromagnetics, it is not necessarily a changing electric field that creates a change in magnetic field, but instead an accelerating charge. and it is this charge that creates both the electric and magnetic field. Again, from my understanding, a changing magnetic field is not generated by a changing electric field, but instead just happens to always be present perpendicular to a changing electric field due to the laws of electromagnetism.   Am I wrong? Or is the "mutual generation" concept between the electric and magnetic components of an EM wave an actual thing? I want to run a command line that opens a new chrome window with another profile. I tested the following commands: Preconditions:  I have two profiles: Profile 1 and Profile 2  Chrome is already running with Profile 1   open -a &quot;Google Chrome.app&quot; --args --profile-directory=&quot;Profile 2&quot; The above command does nothing other than bringing focus to the currently running chrome with Profile 1 I also tried: open -a &quot;Google Chrome.app&quot; --args --profile-directory=&quot;Profile 2&quot; --new-window The effect is the same. I want to run a command line that opens a new chrome window with Profile 2 while there is already a Chrome window running with Profile 1 Divisibility is transitive: $\ a\mid b\mid c\,\Rightarrow\ a\mid c$ As the title says, if a number is divisible by a number, is it always divisible by that number's factors?  An example being that $100$ is divisible by $20$, it is also divisible by $10, 5, 4, 2$ as well?  Does this always apply? Calculating $\lim_{n\to\infty}\sqrt[n]{2^n-n^2}$ I want to keep Ubuntu but remove Windows. I have a simple skull model, to which I applied the subdivision modifier. For the most part everything works as expected, except I keep getting these weird sharp vertices and I can't seem to figure out how to flatten them.    I'm using Blender 2.8. Is this some kind of feature I can disable/enable for particular vertices? The distance between the sharp vertices and the gray outline differ.    Any suggestions please? Thank you!  EDIT: I also tried selecting as both - vertexes and edges and then applied Edge->Clear Sharp, but nothing changed. I use Ubuntu 12.04 64-bit, I did the following: sudo gedit /etc/apt/apt.conf and added  APT::Install-Recommends "false"; APT::Install-Suggests "false";    But it did not work. When I try to install a package, it still wants to install the suggested and recommended packages. How can I solve this? The set of limit points of the sequence $1,\frac12,\frac14,\frac34,\frac18,\frac38,\frac58,\frac78,\frac1{16},\frac3{16},\ldots$ How to get cross-references to multiple figures? Let's say we have $x^2=25$ So we have two real roots ie $+5$ and $-5$.  But if we were to differentiate on both sides with respect to $x$ we'll have the equation $2x=0$ which gives us the only root as $x=0$.  So does differentiating on both sides of an equation alter it? If it does, then how do we conveniently do it in Integration by substitutions? If not then what exactly is going on here ?

If the earth would stop spinning, what would happen? Initializing C# auto-properties Is there a known mathematical equation to find the nth prime? I've solved for it making a computer program, but was wondering there was a mathematical equation that you could use to solve for the nth prime? The title says it all, just wondered if accessing the iOS will count towards your consecutive visited days. Is there a general method (which can be implemented by hand) to finding the $n$-th roots of $2 \times 2$ matrices? Is there a similar method for a general $m \times m$ matrix? (for $n &gt; 1$ and $n\in\mathbb{Z}$) Why LastModifiedbyid in Trigger.new gives old value I have noticed the strange behaviour of salesforce due to which even my code broke down in production.  I was trying to stop the user from updating some field..I used before udpate trigger and code like Trigger.new[i].LastModifiedbyId..  Ideally it should give the current user in Trigger.new[i].LastModifiedbyId in  but it gives oldrecordLastModifiedbyId..  Although userinfo.getuserid resolves the problem later.  Any idea about this behaviour of salesforce.
