What to do if Magick don`t load saved weapon?
Is there a way to preserve a weapon in Magicka within a saved multiplayer game
Crookshanks is Hermione's familiar in PoA, GoF, and OOTP. I cannot recall mention of Crookshanks following OOTP, though. What happened to Crookshanks? Does canon refer to Crookshanks in either HBP or DH? Reading/writing an INI file Is there any class in the .NET framework that can read/write standard .ini files:  [Section] &lt;keyname&gt;=&lt;value&gt; ...   Delphi has the TIniFile component and I want to know if there is anything similar for C#? I can't find my other HDD New Ubuntu user here... I have Ubuntu on my 250GB SSD and I have another 500GB on my laptop that Ubuntu can't find. I'm not sure where or how to start finding it. mysql doesn't ask for root password when installing If $A$ is a ring and $S=\{1,f,f^2,f^3,...\}$ a multiplicative set of $A$, prove that $\mathrm{Spec}(A_f)=\mathfrak{V}((f))^c$.   Notation: $A_f=S^{-1}A$ and $\mathfrak{V}((f))=\{P \in \mathrm{Spec}(A): P \supset (f)\}$  My attempt:   On one hand, if $P \in \mathrm{Spec}(A)$ and $P \cap S$ is empty then we identify $\mathrm{Spec}(A_f)=\mathrm{Spec}(S^{-1}A)=\{P \in \mathrm{Spec}(A): P\cap S= \emptyset\}$.  On the other hand, $\mathfrak{V}((f))^c=\{P \in \mathrm{Spec}(A): P \nsupseteq (f)\}$.   So the exercise is equivalent to prove: $$\{P \in \mathrm{Spec}(A): P\cap S =\emptyset\}=\{P \in \mathrm{Spec}(A): P \nsupseteq (f)\},$$ but I can't continue so I'd appreciate if somebody could help me.   Thanks in advance. For every $g\in G$ there exists an $h\in G$ such that $g = h^3$ Let G be a finite group whose order is not divisible by $3$. Show that for every $g\in G$ there exists an $h\in G$ such that $g = h^3$. How do I declare and initialize an array in Java? Difference between var = {} and var = []? PHP & MySQL: mysqli_num_rows() expects parameter 1 to be mysqli_result, boolean given Finding $\int \frac{dx}{a+b \cos x}$ without Weierstrass substitution. I saw somewhere on Math Stack that there was a way of finding integrals in the form $$\int \frac{dx}{a+b \cos x}$$ without using Weierstrass substitution, which is the usual technique.   When $a,b=1$ we can just multiply the numerator and denominator by $1-\cos x$ and that solves the problem nicely.   But I remember that the technique I saw was a nice way of evaluating these even when $a,b\neq 1$. Some images shown outside of preview rectange Some images shown outside of preview rectange before uploading, eg: I am looking for a textbook that treats the subject of Special Relativity from a geometric point of view, i.e. a textbook that introduces the theory right from the start in terms of 4-vectors and Minkowski tensors, instead of the more traditional "beginners" approach. Would anyone have a recommendation for such a textbook ?  I already have decent knowledge of the physics and maths of both SR and GR ( including vector and tensor calculus ), but would like to take a step back and expand and broaden my intuition of the geometry underlying SR, as described by 4-vectors and tensors. What I do not need is another "and here is the formula for time dilation..." type of text, of which there are thousands out there, but something much more geometric and in-depth.  Thanks in advance. The limit of truncated sums of harmonic series, $\lim\limits_{k\to\infty}\sum_{n=k+1}^{2k}{\frac{1}{n}}$ What is the sum of the 'second half' of the harmonic series?  $$\lim_{k\to\infty}\sum\limits_{n=k+1}^{2k}{\frac{1}{n}} =~ ?$$  More precisely, what is the limit of the above sequence of partial sums? Generating list of manually installed packages and querying individual packages We are beginning to go down the path of mobile browser support for an enterprise e-commerce webapp (Java/Servlet based).  Of course there are many decisions to be made, but it seems to me the cornerstone is to be able to reliably detect mobile browsers, and make decisions on the content to be returned accordingly.  Is there a standard way to make this determination (quickly) based on the http request, and ideally glean more information about the given browser and device making the request (screen size, html capabilities, etc?).  I would also appreciate any supplemental information that would be of use from someone who has gone down this path of taking an existing large scale enterprise webapp and architect-ing out mobile browser support from the development side.  [edit] I certainly understand the request header and the information about a database of standard user agents is a great help.  For those talking about 'other' request header properties, if you could include similar standardized name / resource of values that would be a big help.  [edit] Several users have proposed solutions that involve a call over the wire to some web service that will do the detection.  While I'm sure this works, it is not a good solution for an enterprise e-commerce site for two reasons: 1) speed.  A call over the wire for every page request to a third party would have huge performance implications.  2) dependency/legal.  We'd tie our website response time and key functionality to their service, which is horrible for legal and risk reasons. On some Microsoft Access queries, I get the following message:  Operation must use an updatable query. (Error 3073).  I work around it by using temporary tables, but I'm wondering if there's a better way.  All the tables involved have a primary key. Here's the code:  UPDATE CLOG SET CLOG.NEXTDUE = (     SELECT H1.paidthru      FROM CTRHIST as H1     WHERE H1.ACCT = clog.ACCT AND     H1.SEQNO = (         SELECT MAX(SEQNO)          FROM CTRHIST          WHERE CTRHIST.ACCT = Clog.ACCT AND          CTRHIST.AMTPAID &gt; 0 AND         CTRHIST.DATEPAID &lt; CLOG.UPDATED_ON     ) ) WHERE CLOG.NEXTDUE IS NULL; As a non-native speaker, I cannot grasp any difference between the expressions "here we go" and "there we go": both expressions seem to underline an event that is going to happen immediately.  Is there any subtle usage detail that I am missing? How are these AES MixColumn multiplication tables calculated? I'm using the mul2, mul3, mul9, mul11, mul13 and mul14 tables for the MixColumn and InvMixColumn steps in AES-128. However, I got these off some Github repository, and now I'm looking for an actual source explaining how these were calculated and so on.  I cannot find anything proper on Google, can anyone help me out? Why is ATP the most prevalent form of chemical energy storage and utilization in most cells? Why does change in speed of a wave make it refract? When a light wave enters a medium with a higher refractive index (e.g. from air to standard glass) and its speed decreases, why does that make it refract/bend?  I understand that wavelength decreases and frequency stays the same and therefore its speed decreases, but I can't find anywhere whatsoever why the speed decrease cause the wave to refract. So could someone please explain this?
