Why in Java we have to write Enum.Val but in switch only Val?
Why can't an enum value be fully qualified in a switch statement?
Possible A* Optimizations I was trying to change my username and also my home directory (/home/username) and my system started to crash. I deleted the passwd file but I had a backup named passwd_bkp. I tried to rename this passwd_bkp as passwd and it did not work. No commands were being executed... I was in a terminal window.   I restarted my system and now I cannot log in. GRUB gives two options: Linux and recovery mode.   I tried to open a sessions as root but it says the filesystem is corrupted. I cannot access my files.  Did I lose all my files? Finding the Mobius Transformation that maps open unit disk onto itself Hi I am trying to find all the Mobius transformations that map unit open disk onto itself i.e., if $|z|&lt;1$ then $|f(z)|&lt;1$ where $f(z)=\frac{az+b}{cz+d}$. I did so far \begin{align*} &amp;\Big|\frac{az+b}{cz+d}\Big|&lt;1\\ \Rightarrow &amp; |az+b|&lt;|cz+d|\\ \Rightarrow &amp; |az+b|^2&lt;|cz+d|^2\\ \Rightarrow &amp; |az+b||\bar{a}\bar{z}+\bar{b}|&lt;|cz+d||\bar{c}\bar{z}+\bar{d}|\\ \Rightarrow &amp; |a|^2|z|^2+|b|^2+2\text{Re }(az\bar{b})&lt;|c|^2|z|^2+|d|^2+2\text{Re }(cz\bar{d}) \end{align*}   After that I am stuck. Can anyone help me. I would be obliged...Thanks in advance. I have used quite some time searching for a solution to my compile problem. The document worked fine untill yesterday. After adding some new references, compiling stoped working properly. I have however used latex only for a few months, so the error might be an easy fix.   My error code in the blg file is:    [836] Utils.pm:209&gt; ERROR - BibTeX subsystem:  C:\Users\andre\AppData\Local\Temp\yb9w7ETEpQ\thesisbiblo.bib_16800.utf8,  line 1375, syntax error: found ",", expected one of: number, name (entry  type, key, field, or macro name), end of entry ("}" or ")") or quoted string  ({...} or "...").    I have biber 2.11 and miktex 2.9 and thought it could have been the cache file as suggested in a previous thread with 2.11 versions, but it did not do the trick to delete that either.

What conventions are there, who uses them, and when am I obliged to follow them? Was V'ger responsible for the creation of the Borg? I remember reading somewhere a theory that  (the being that the Voyager probe had become in Star Trek: The Motion Picture) was somehow responsible for the creation of the Borg.  Is this canonical?  Where does the theory come from?  And how exactly did it go down? This should be a fairly trivial problem. I'm trying to open an ofstream using a std::string (or std::wstring) and having problems getting this to work without a messy conversion.  std::string path = ".../file.txt";  ofstream output;  output.open(path);   Ideally I don't want to have to convert this by hand or involve c-style char pointers if there's a nicer way of doing this? is_active_sidebar() Always Returns False Would the latter be an issue with the funding body, when the project proposal and budget only covers the expenses for hiring one postdoc? Note: it is the supervisors who got the grants, not the postdocs themselves. How can I draw a dot under a symbol in math mode? Show $x^p-t$ has no root in the field $\mathbb{F}_p(t)$ I don't think I fully understand.  Let's say there is a root $x_0 \in K=\mathbb{F}_p(t)$, where $p$ is a prime number.  Then $x_0 = \frac{P(t)}{Q(t)}$ for some polynomials $P,Q \in \mathbb{F}_p[t]$. We can assume $\gcd(P,Q)=1$  and $x_0^p-t= \frac{(P(t))^p}{(Q(t))^p}-t= \frac{P(t)^p-tQ(t)^p}{Q(t)^p} =0$, so coefficients of $P(t)^p, tQ(t)^p$ must be identical, which contradicts $\gcd(P,Q)=1$,   hence such $x_0$ does not exist and the polynomial has no root in $K$.   am I about right?    anyway, I would appreciate an explanation about $\mathbb{F}_p(t)$, what is $t$? what is the meaning of a variable which does not belong to any specific "world"? I cannot use $t$ as if it was a member of $\mathbb{F}_p$ and hence cannot assume $t^{p-1} = 1 \pmod p$... If $-1&lt;x&lt;1$ show that $\lim\limits_{n \to \infty}{n\,x^n} = 0$. I don't have idea. I only prove that $n\,x^n$ is decreasing. Can I secretly kill every guard in a town? Is it possible to kill all of the guards in a town?  Ideally, I'd like to do this secretly so the entire town doesn't see my deeds and put a bounty on my head.  Edit: I was questing in Markarth and was told by a guard to back off and stop being nosy. I didn't and when I went to the Shrine of Talos I was set upon by a bunch of guards.  Now I have a huge bounty and I had to sneak/kill my way out of the city.  Every time I killed a group of guards the bounty was reduced by $1000, but I still have a $30,000 bounty.  I haven't even been through 1/3 of the city yet and know there has to be a lot of quests, so what do I do?  The only solution seems to kill every single guard (and inhabitant). What is the difference between "twenty-four-hour shift" and twenty-four hour shift"? Just read somewhere about this puzzling puzzle:  What is the difference between:   I'm doing a twenty four-hour shift tonight. I'm doing a twenty-four hour shift tonight. I'm doing a twenty-four-hour shift tonight.   I know number 1 is 20 x 4 hours. Number 2 and 3 is the same as far as I know. Is this true? Meaning of Sun Lamp Size? How does the Southwest Airlines boarding process work? I'm flying this week on Southwest Airlines for the first time. I paid for "Early Bird" automatic checkin and the FAQ mentions something about "A" boarding passes. I have no idea what that means, and I know that Southwest doesn't have assigned seats.  How does the boarding process work and is there anything I should be aware of? Is there a direct, elementary proof of $n = \sum_{k|n} \phi(k)$? Easiest way to import access db (.accdb) into SQL Server 2016? I have a .accfb file from an access 2016 database and am trying to import this database into a SQL Server 2016 developer edition instance.   While I found posts online discussing using import/export data tools in SQL Server and also migration assistant for access, neither have worked out for me.   Does anyone know how to easily move a database from access 2016 to sql server 2016? More specifically an "accdb" file type?  All suggestions are greatly appreciated! How to change background-color on text links on hover but not image links Using Illustrator CS6 to create shape out of multiple paths I am very new to Illustrator, in fact I am only experimenting with it in an attempt to help my friend develop a logo for a new business venture. I managed to draw out the shell of the logo using the line tool and modifying the lines with the anchor tool to get the shape I wanted.  However, I would like to somehow take all of these paths and create one object, or symbol which I can then apply a drop shadow, fill and various other effects too. Currently when I try to do this I get unwanted effects...  I'd appreciate any help on the subject.
