I got a problem. I got some coordinates in Excel. They are written with comma 14459091,1010 ex.  When I try to import them as csv-file into QGIS, it will only create a table and no points. When I look in the properties it says that my "x" and "y" columns are strings.  I use a semicolon to separate the fields.
i have read most of the related postings and answers allready ... (e.g.  and  ... among others)  but (!) unfortunately none of them solved my problem. as someone postet on 2012-01-04 12:27 definition of properly defined *.csvt doesn't effect field-import - they are expected to be numbers and still are string.  her is a sample of my csv  InputID,Mean,Stdev,min,max 1,334.7617168,36.87450474,294.4334857,383.5583136 2,446.3946568,207.949905,153.2494524,613.3182137 and the csvt "Integer","Real","Real","Real","Real"  .. i have already:    checked field names (no blanks), checked separators, ... which are qgis' default because the csv is distance matrix calculation result defined the csvt with simle "Integer","Real" and the precision-type-style "Integer(6)","Real(8.3)" changed country settings in win7, win8, osx 10.9 due to known decimal separator issues   used csv as specified as well as "excel-style" csv (";"-separated)    checked all that in qgis 2.0, 2.2, 2.3(master)   and: at the beginning this problem was related to distance matrix output  ... where qgis calculates the results (and writes the csv-outputs), which of course are numbers (mean, stdev, min, max)  so, initially i was just looking for a straight forward way to use qgis' own calculation results for mapping of distance-distribution ...  is there a way to solve or completely bypass the csv-t issue in a way, i can easily communicate to gis-beginners ?
Normal Subgroup Counterexample Im having trouble with the second part of this question,  Let $H$ be a normal subgroup of $G$ with $|G:H| = n$,  i) Prove $g^n \in H$ $\forall g \in G$ (which i have done)  ii) Give an example to show that this all false when $H$ is not normal in $G$.(which I am having trouble with showing)  Any suggestions? What is the name of the operation $v^T H v$? To find out how something is called is the one thing I don't know how to use Google for.  If I have a vector $v$ and a symmetric matrix $H$, then the operation $v^T H v$ gives me some sort of projection of the matrix $H$ on the vector $v$. For example if $H$ is the Hessian, the operation gives me the second derivative in the direction of $v$.  What is the name of this operation? SEO preference: does a site with WWW rank better than without WWW? How do I explain current and voltage to a lay man? A man asked me this question in suburban train when I told him that I am an electrical engineer. Of course I replied him that current is the flow of electrons and in order for the current to flow there should be a potential difference between them. But the man didn't know what electron or potential difference was either. Why does my shell script choke on whitespace or other special characters? Is it better in C++ to pass by value or pass by constant reference? Is it better in C++ to pass by value or pass by constant reference?  I am wondering which is better practice.  I realize that pass by constant reference should provide for better performance in the program because you are not making a copy of the variable. I want to show that if a real orthogonal matrix $A$ has determinant $-1$ then $\lambda=-1$ must be an eigenvalue of $A$.  I have proven this in a long-winded way and I was wondering if these is a quick way of seeing it. Where do the regions of Westeros appear to align as of the season 6 finale? Based on , my understanding is that there are 9 regions of Westeros subject to the rule of the Iron Throne, from Dorne joining up to Cersei killing Robert.  With whom does [insert region] align in what appears to be Daenerys vs Cersei?   Kingdom of the North -- Daenerys probably but currently busy with White Walkers Kingdom of the Mountain and the Vale -- Daenerys probably but currently busy with White Walkers (supposedly; depends on what Littlefinger has in mind) Kingdom of the Isles and Rivers (Iron Islands) -- Daenerys Kingdom of the Isles and Rivers (Riverlands) -- Cersei because the Freys are with the Lannisters? Kingdom of the Rock -- Cersei because she is a Lannister Kingdom of the Stormlands -- Cersei? Kingdom of the Reach -- Daenerys after invitation of Varys and Ellaria Principality of Dorne -- Daenerys after invitation of Varys presumably Crownlands -- Cersei since Cersei is currently occupying the Iron Throne   Am I understanding this right? Anything wrong? The projection of an ellipse is still an ellipse While studying the problem of determining the orbit of a binary star system, my astronomy notes say: "the projection of an ellipse onto a plane is still an ellipse (except the special case in which it's a segment)". How could I prove this?  EDIT: As suggested i'm adding what I know about ellipses. I know the basics of ellipses in the plane, the equation of an ellipse in a plane in cartesia coordinates, the equation of an ellipse in polar coordinates, the fact that ellipses can be obtained by the intersection of planes with a cone. In my geometry course we defined ellipses as the the points of the plane such that the ratio between the distance from a point and a line is constant and less than 1. I also know that the sum of the distances of the points of the ellipse from the foci is constant. VMware Linux Server -- how can you tell if you are a vm or real hardware? An interesting question.  I have logged into a Linux (most likely SuSE) host.  Is there some way that I can tell programmatically that I am a VM host or not?    Also assume that the vmtools are not installed. Here's a question that I share:  Show that if $D$ is a countable subset of $\mathbb R^2$ (provided with its usual topology) then $X=\mathbb R^2 \backslash D $ is arcwise connected. list all suggested packages for currently installed packages Java - Could not find the main class What's the difference between magnetic fields $H$ and $B$? As per :  &quot;The term (Magnetic Field) is used for two distinct but closely related fields denoted by the symbols $B$ and $H$, where $H$ is measured in units of amperes per meter in the SI. $B$ is measured in teslas in the SI.&quot;  So, the two are closely related. Why do we need two, then? Could just one be used? As I remember from the university, for vacuum the Maxwell's equations are written usually in terms of $B$, while for media in terms of $H$ (and $B=\mu H$). Example of a group $G$ such that $G = N_1\cdots N_n$ and $N_i \cap N_j = \{e\}$ for all $i \neq j$ but $G$ is not the internal direct product of them. I was trying to find an example of a group $G$ and normal subgroups $N_1 , \ldots , N_n$ such that $G = N_1\cdots N_n$ and $N_i \cap N_j = \{e\}$ for all $i \neq j$ and yet $G$ is not the internal direct product of  $N_1, \ldots , N_n$ .  It is easy to show that G is the internal direct product of normal subgroups $N_1 , \ldots , N_n$ iff  (i) $G = N_1\cdots N_n$  (ii) $N_i\cap (N_1 \cdots N_{i-1}\cdots N_{i+1} \cdots N_n) = \{e\}$ for $i = 1, 2, \ldots, n$.  So I guess the question boils down to produce an example of a group $G$ and its normal subgroups  $N_1 , \ldots , N_n$ such that   (1) $G = N_1\cdots N_n$  (2) $N_i \cap N_j = \{e\}$ for all $i \neq j$   but     (3) $N_i \cap (N_1 \cdots N_{i-1} N_{i+1} \cdots N_n) \neq \{e\}$ for at least one $1 \le i \le n.$ Thanks in advance for help.... What changes after peer review but prior to final submission are acceptable for a conference paper? Let $x_{1},x_{2},\cdots,x_{n}$ be real numbers. Show that     $$\sum_{i,j=1}^{n}|x_{i}+x_{j}|\ge n\sum_{i=1}^{n}|x_{i}|.$$   I think this problem may be solved using nice methods, but I can't find them yet; I know this may be of use: $$|a|+|b|\ge |a+b|.$$ But I can't make it work. Thank you everyone. An example for a homomorphism that is not an automorphism Prove: if $a,b\in G$ commute with probability $>5/8$, then $G$ is abelian Suppose that $G$ is a finite group. If $P( ab=ba ) &gt;5/8$, prove $G$ is abelian. Should I keep 32bit or 64 bit Windows 10 on my x64 based Intel Atom Z3735F cpu on 2gb ram non-upgradable laptop I have an Acer Aspire Switch 10 SW5-012 detachable notebook which has 2GB of RAM based on an x64 based processor. I got it with a 32 bit version of windows 8 but upgraded to windows 10 recently. But before I do anything else, I was considering if I'd be having Better performance with the 64 bit version of windows 10. Would it make my notebook perform better since it's based on an x64 based Intel Atom Z3735F? Or should I just stick to the 32 bit version of windows 10?
