It’s 3rd time, I'm starting my  laptop and it’s showing this error.     Realtek PCIe GBE Family Controller Series v2.41 (06/08/11)      PXE-E61: Media test failure, check cable.      PXE-M0F: Exiting PXE ROM.      No Boot Device Found. Press any key to reboot the machine.   Please check the image below for precise error and details.  First time I tried to press keys, also checked setup but didn’t help. Everytime It got restarted and shows the same error again. Then I powered off and on again and it starts working. Then next day same issue but worked fine when I re-started via power button and today’s the same.  Any help what to do?

"He acted strange(ly?)" Where can I find good literature for beginners? I am trying to find some database tutorials,books and similar, since I have started this course in college, and received some material, but it is really hard to manage through all the info on the net. I searched through the questions on the site but didn't find any. Thankfull for all your input. If I enter my password correct first time, I login as normal.  If I enter my password wrong, it says invalid password. If I attempt to enter the correct password now then the screen freezes and doesn't go to dock as normal. I must restart using a physical button or shutdown to get out. Login works normally after restart, assuming I get it right first time.  EDIT:  After entering a wrong password, if I click cancel and then go back to my user to login, it works fine. Limit of $\frac{\log(n!)}{n\log(n)}$ as $n\to\infty$. I have Ubuntu 14.04 and two monitors. When I open applications I need some of them to be on the primary monitor and others On the secondary. At the moment, apps always open in the primary monitor.   I have dash icons only on one (left) display, so I can't launch apps using the cursor or active window setting from Compiz. Prove the following integral inequality: $\int_{0}^{1}f(g(x))dx\le\int_{0}^{1}f(x)dx+\int_{0}^{1}g(x)dx$ Suppose $f(x)$ and $g(x)$ are continuous function from $[0,1]\rightarrow [0,1]$, and $f$ is monotone increasing, then how to prove the following inequality: $$\int_{0}^{1}f(g(x))dx\le\int_{0}^{1}f(x)dx+\int_{0}^{1}g(x)dx$$ Cannot log in with Apple ID after performing password reset My wife forgot the password to her Apple ID account. Her Macbook Air (OS X Yosemite) restarted to install some updates. She has her user account set up through her Apple ID account.  Since she forgot the password she reset it from my laptop.  She can log in to iCloud and Apple ID with the new password, but cannot log in with the new password on the Air.  When she tries to log in she is greeted with this message:     "This account uses an iCloud password to log in. If you need to change   the password, use another device to change it at appleid.apple.com." Given a DateTime representing a person's birthday, how do I calculate their age in years? How tall is Supreme Leader Snoke? In Star Wars: The Force Awakens, we see Supreme Leader Snoke a few times dispensing orders to his subordinates.      However, we always see him communicating via hologram, and we've seen in previous Star Wars films that these holograms are often projected at a different size than the original person is.   So how tall is he really?  I don't think we ever got a good shot of him with something to give a sense of scale. TikZ: Intersection of two lines what is the easiest way to determine the intersection of two lines?

When it's raining, would you get less wet if you run or more wet?  I think you will get less wet, because rain is coming down in a constant volume and if you run you will have a shorter amount of time you will get less volume  I'm not too sure though, some people say when you run you are running into a more volume of rain because rain is not all coming up to down, it will hit you more horizontally Are there any rulesets or laws for Q or Q continuum? Anything, that would prevent them from doing... anything? Or at least limit them from doing something really bad?  In "" episode Q explains to  that they can do, have, get, become anything they want or appear anywhere they want, with just a snap of fingers. If that is true and if there are absolutely no borders or limits, they can't pass, then how can universe work in general? Or, how did it manage to exist so far?  I mean -- any Q could wipe out Borg, entire human population or even entire universe... with just a snap of fingers. What could prevent Q from doing that? Modern ice-age/plans for weapon hidden in genome What is likely to happen when you plug two ends of a network cable to a single switch/router?

Could $X^3 + X + 1$ have a root in $E?$ Consider the irreducible polynomial $g = X^4 + X + 1$ over $F_2$ and let $E$ be the extension of $F_2 =$ {0, 1} with a root $α$ of $g.$  Could $X^3 + X + 1$ have a root in $E?$  When working through this sheet Ive come across this question in which im not sure how to answer so any help will be appreciated Where does the "apply bonuses and penalties in the most beneficial order" rule come from, if it exists? I have seen quoted several places on the internet a rule that one can apply bonuses and penalties in the most beneficial order.  An example I come across frequently (as a druid) is the combination of Natural Bond and . Natural Bond increases your effective druid level for determining the stats of animal companions but cannot increase it beyond your character level. Choosing an alternative animal companion lowers your effective druid level for determining the same stats. The "most beneficial order" rule is used to justify applying the level penalty before the natural bond bonus in order to get around the character level cap on natural bond.  Does this rule actually exist? If so, where does this rule originate? I would like to be able to cite a reliable source for my GM. Can you be tripped by an AoO while standing up? When is it appropriate to use the original pronunciation of a foreign word versus the English pronunciation? When reading to an audience, or speaking in conversation, when is it appropriate to use the original pronunciation of a foreign word versus the English pronunciation (assuming you know the appropriate pronunciation for it)? Is it considered rude, or condescending? Or is it considered a mark of being knowledgeable?  One of the things to consider are place names. When referring to Paris, France, should it be pronounced with the silent 'S' as the French would say it, or with the 'S'? Should Hiroshima be pronounced as a Japanese speaker would pronounce it slightly more emphasis on RO, rather than the SHI? Should Mount Pinatubo be pronounced as a Filipino speaker would pronounce it with shorter stronger vowels, or the longer vowels? (e.g. Pi as is 'pick' rather than 'pea'.) Should Wichita be pronounces as the original "shi" rather than the modern "chi"?  Pronounce pesos or sombrero as a Spanish speaker 'eh' or the English 'ay'?  (I can't think of other common words right now that aren't words taken from other languages like hurricane, boondocks, tornado, etc. which I think have (correctly) changed to English pronunciations.)
