Unknown Additional Driver: Processor microcode firmware for Intel CPUs for intel-microcode After upgrading to 15.04, I have one additional driver (it did not appear in 14.10). What is the purpose of this driver and should I enable it?
How did Princess Leia survive this? In the Last Jedi movie, there is a scene where      her spaceship is taken down, Princess Leia is thrown into outer space, and seen floating there, frozen.    However, she manages to survive this, while any ordinary human being couldn't.   How did she manage this? Is this done by using the Force? How many distinct functions can be defined from set A to B? Reese's boyfriend seems to constantly be asleep. When I try and talk to him, she warns me that he's been hard at work all night, but I can't actually enter the shop at night.   Is there any way to talk to him or any benefit for doing so? I've tried to talk to him daily for a week (thinking it was something akin to talking to Sable) but I've had no luck. Trying to come in after-hours doesn't work. The third formula on the  states that $$\varphi (mn) = \varphi (m) \varphi (n) \cdot \dfrac{d}{\varphi (d)} $$ where $d = \gcd(m,n)$.  How is this claim justified?  Would we have to use the Chinese Remainder Theorem, as they suggest for proving that $\varphi$ is multiplicative? I am trying to make an explosion in Blender.  I am having a problem with the smoke simulation with the Cycles rendering engine. More specifically, I have been able to render smoke, but flames do not show up. In the viewport however, everything looks perfectly fine.  The render looks like this:    But in the viewport, it is clear that there are flames. Does anyone have any idea what is going on?     This is NOT a duplicate of  because I have Flame Rate set to 1.0 Where are temporary files in Chrome stored?

The point is to illustrate just how poorly the camera tracker calculated: when the box is at a marker placed at the top of a faraway building on the left, it is actually visually much larger than when it is at the tracking marker closest to where the real camera was. I went to great lengths to be sure that the camera's sensor size and focal length are correct, and manually placed and followed all markers to be sure they were accurately tracking.   There is not a lot of parallax motion over the 800 frames, but there should have been enough to at least know that the point closest to the camera moved more than the point furthest away. Sometimes it seems to work, sometimes it doesn't. Does anybody know how to improve this? I am being prompted with the following error while using \pagestyle{headings} on a book class LaTeX document:  Overfull \hbox (240.44835pt too wide) has occurred while \output is active \OT1/cmr/m/sl/12 CHAPTER 1. THE CITY OF CARTHAGE WAS THE CENTRE OF THE ANCIENT CARTHAGINIAN CIVILIZATION \OT1/cmr/m/n/12 2   The following is the offending code:  \documentclass[12pt,letterpaper,oneside]{book}  \pagestyle{headings}   \begin{document}  \pagenumbering{arabic}  \chapter{The city of Carthage was the centre of the ancient Carthaginian civilization} The city of Carthage was the centre of the ancient Carthaginian civilization. The city developed from a Phoenician colony of the 1st millennium BC into the capital of an ancient empire.[2] The area of Carthage was before inhabited by Berber people who also became the bulk of Carthage's population and constituted a significant part of its army, economy and administration. Native Berbers and settling Phoenicians in Carthage mixed in different ways including religion and language, creating the Punic language and culture.  The name of Carthage, Latin: Carthago or Karthago,  meaning "New City"   The first civilization that developed within the city's sphere of influence is referred to as Punic (a form of the word "Phoenician") or Carthaginian. The city of Carthage is located on the eastern side of Lake Tunis across from the centre of Tunis. According to Greek historians, Carthage was founded by Canaanite-speaking Phoenician colonists from Tyre (in modern Lebanon) under the leadership of Queen Elissa or Dido. It became a large and rich city and thus a major power in the Mediterranean. The resulting rivalry with Syracuse, Numidia, and Rome was accompanied by several wars with respective invasions of each other's homeland.  Hannibal's invasion of Italy in the Second Punic War culminated in the Carthaginian victory at Cannae and led to a serious threat to the continuation of Roman rule over Italy; however, the Romans gained the upper hand by invading Africa and defeating Carthage at the Battle of Zama in 202 BC. Following the Third Punic War, the city was destroyed by the Romans in 146 BC. However, the Romans refounded Carthage, which became the empire's fourth most important city and the second most important city in the Latin West. It later became the capital of the short-lived Vandal kingdom. It remained one of the most important Roman cities until the Muslim conquest, when it was destroyed a second time in 698.  The ancient Greek philosopher Aristotle wrote extensively on Carthaginian politics, and he considered the city to have one of the best governing institutions in the world, along with those of the Greek states of Sparta and Crete.[5][6]  \section{Topography} Carthage was built on a promontory with sea inlets to the north and the south. The city's location made it master of the Mediterranean's maritime trade. All ships crossing the sea had to pass between Sicily and the coast of Tunisia, where Carthage was built, affording it great power and influence.  \end{document}    The \hbox refers to:      How can I solve this issue using \pagestyle{myheadings}? Or how can I solve this issue keeping the book class heading format? Evaluate the following limit of finite sum Evaluate the limit $$\lim_{n\to \infty}\frac{1}{n}\sum_{k=0}^{[n/2]}\cos \left(\frac{k\pi}{n}\right)$$  I tried through considering two cases : (i) When $n$ is even (ii) when $n$ is odd.  When $n$ is even then the limiting value is $\frac{1}{\pi}$. But when $n$ is odd then ??  Case 1 : $n$ is even..  Then , take $n=2p$ where $p$ is positive integer. Then $$\lim_{n\to \infty}\frac{1}{n}\sum_{k=0}^{[n/2]}\cos \left(\frac{k\pi}{n}\right)$$  $$=\lim_{p\to \infty}\frac{1}{2p}\sum_{k=0}^{p}\cos\left(\frac{k\pi}{2p}\right)$$  $$=\frac{1}{2}\int_0^1\cos(\pi x/2)\,dx$$  $$=\frac{1}{\pi}.$$  Case 2 : When $n$ is odd.  Take, $n=2p+1$ , where $p$ is a positive integer. Then ,   $$\lim_{n\to \infty}\frac{1}{n}\sum_{k=0}^{[n/2]}\cos \left(\frac{k\pi}{n}\right)$$  $$=\lim_{p\to \infty}\frac{1}{2p+1}\sum_{k=0}^p\cos\left(\frac{k\pi}{2p+1}\right)$$  From here how I proceed ? Well, luckily I got this error on my test environment. I'm so scared about this error that I disabled all logon triggers I was using on production environment.   I created the famous logon trigger, and I put a database in offline mode just to mess with something else. Then I discover that because the trigger can't find the table, I can't access the instance anymore. There are plenty of questions related to this, but even doing everything I could find, I still can't acces the instance, not even with SQLCMD.  I'm doing this:  sqlcmd -S server\instance -U sa -P &lt;pass&gt;  -A   If I don't use -A I receive the famous error:  logon failed for sa due trigger execution.   If I use -A:     Sqlcmd: Error: Microsoft ODBC Driver 11 for SQL Server : SQL Server   Network Interfaces: An error occurred while obtaining the dedicated   administrator connection (DAC) port.

Sqlcmd: Error: Microsoft ODBC Driver 11 for SQL Server : A   network-related or instance-specific error has occurred while   establishing a connection to SQL Server.

Why i'm not able to connect to the sql server    sql server express here.  I could enable SQL Browser, but I still can't access it.  I don't think this question is duplicated because is not about the trigger, is about Why I can't access the server with SQLCMD. I pretty much know how to fix this. I just don't know how can I acces sql server without triggering the trigger.

Program to create EMF that conserves transparency What open source tools allow for the creation of EMFs that conserve transparency in ArcMap?  I tried VeryPDF and Any DWG to Image Converter, neither on actually gave me a vector file that provided transparency.

What determines who gets or becomes an MVP? This hasn't been asked yet, but what determines how or who gets an MVP award in CS:GO? After a match, there's always a little blurb that first states who got MVP first, and then a random fact (Player X got Y knife kills, Player X lasted Y rounds without dying, etc.).  Do these two factors both "factor" into getting an MVP award? Is it a set percentage of enemies you kill? Is there a priority list (ie, planting bomb, defusing, etc.)? Can $\frac{\sqrt{3}}{\sin20^{\circ}}-\frac{1}{\cos20^{\circ}}$ have two values? Maintain the aspect ratio of a div with CSS How to remove the top horizontal bar in fancyhdr?

This is what I do now:  \documentclass{article} \usepackage{fancyhdr} \pagestyle{fancy}  \lfoot{text} \cfoot{text 2} \rfoot{text 3}  \begin{document} Foo Bar \end{document} First I tried to use integration: $$y=\lim_{n\to\infty}\frac{a^n}{n!}=\lim_{n\to\infty}\frac{a}{1}\cdot\frac{a}{2}\cdot\frac{a}{3}\cdots\frac{a}{n}$$ $$\log y=\lim_{n\to\infty}\sum_{r=1}^n\log\frac{a}{r}$$ But I could not express it as a riemann integral. Now I am thinking about sandwich theorem.  $$\frac{a}{n!}=\frac{a}{1}\cdot\frac{a}{2}\cdot\frac{a}{3}\cdots\frac{a}{t} \cdot\frac{a}{t+1}\cdot\frac{a}{t+2}\cdots\frac{a}{n}=\frac{a}{t!}\cdot\frac{a}{t+1}\cdot\frac{a}{t+2}\cdots\frac{a}{n}$$ Since $\frac{a}{t+1}&gt;\frac{a}{t+2}&gt;\frac{a}{t+1}&gt;\cdots&gt;\frac{a}{n}$ $$\frac{a^n}{n!}&lt;\frac{a^t}{t!}\cdot\big(\frac{a}{t+1}\big)^{n-t}$$ since $\frac{a}{t+1}&lt;1$, $$\lim_{n\to\infty}\big(\frac{a}{t+1}\big)^{n-t}=0$$ Hence, $$\lim_{n\to\infty}\frac{a^t}{t!}\big(\frac{a}{t+1}\big)^{n-t}=0$$ And by using sandwich theorem, $y=0$. Is this correct?
