C# generics: how to simplify call of the specific type
How do I use reflection to call a generic method?
Can a 20V 4.51A power supply be used with a computer that requires a 19V 3.42A power supply? Intellij shortcut for quick call hierarchy Is there a shortcut key to bring up the call hierarchy of a method inline with the code, in the quick menu format, rather than bringing up the call hierarchy panel? Cam I have two GFCIs connected to one double gang box in my laundry room and if so can I do a single line connection so that they both can work independently?  I have a 12/2 going from the panel through conduit (copper wire) to the double gang box. I want to have each GFCI to run independently without using the load. Why, in case one shuts off the other isn't affected. the double gang box is standard. the device is a Leviton 20 amps. I was told that you can run 12/2 from the panel to the first GFCI black and white. Then connect the second GFCI using a jumper and attaching it to he second GFCI. Is this acceptable by code. we use a washer,dryer in the laundry and the garage heavy machinery. so why should this be a problem running two independent? Let V denote the Klein 4-group. Show that $\text{Aut} (V)$ is isomorphic to $S_3$ After a week in my Abstract Algebra class, the professor proposed this as a problem. I'm not entirely sure where to begin. $ V = \{ e, \tau, \tau_1, \tau_2 \}$, so I'm not sure exactly what is meant by $\text{Aut} (V)$. Is it simply saying that the only way to have an automorphism on $V$ is to rearrange the order of the elements of $V$ and therefore $\text{Aut} (V) \cong S_3$? How do I turn on workspaces? (Why do I only have one workspace?) Integral $\int\!\sqrt{\cot x}\,dx $ Specifying element type for DXF creation using ogr2ogr I am trying to create a DXF from a Polygon Shapefile using ogr2ogr:  ogr2ogr -f DXF parcels.dxf parcels.shp   The problem is that the polygons are written as hatch elements.    How do I specify that ogr2ogr should create LWPOLYLINE elements (Or any other )?  I have tried this from command line and from QGIS 'save as' option with the same result.  I don't remember this being an issue in the past, but seems like it started with GDAL version 1.10.x. What is a good, short, word to describe a software engineer? What should I call a person who write software, computer programs ? I know he/she is a software engineer, can I call him/her as "Coder"? How to check if a string contains a substring in Bash I have a string in Bash: string=&quot;My string&quot;  How can I test if it contains another string? if [ $string ?? 'foo' ]; then   echo &quot;It's there!&quot; fi  Where ?? is my unknown operator. Do I use echo and grep? if echo &quot;$string&quot; | grep 'foo'; then   echo &quot;It's there!&quot; fi  That looks a bit clumsy. $(n+1)$th prime $p_{n+1}$ less than or equal to $p_1p_2\dots p_n+1$ Align equation left Here is my split equation:  \documentclass{article} \usepackage{amsmath} \begin{document} \begin{equation} \begin{split} a_{ijk} =&amp; \frac {Pr(M_{I} =2  \&amp;  M_J=1 \&amp; M_K =1 | I=i , J=j , K=k)}{Pr (M_I =1 \&amp; M_J =1 \&amp; M_K=1 | I=i , J=j)} \\             =&amp; \frac {\mu_{ijk211}}{\mu_{ijk111}}\\ \end{split} \end{equation} \end{document}   I want to align this equation to the left. Is this possible in an equation environment? Series with denominator that is square of product of consecutive numbers Evaluate $\sum_{k=1}^{\infty} \frac{1}{k^2(k+1)^2}$.   I've tried to use a telescoping approach, but it doesn't seem to work. It doesn't also seem to converge to a "pretty" value as well. equivalent date from GNU to solaris Is there a known mathematical equation to find the nth prime? I've solved for it making a computer program, but was wondering there was a mathematical equation that you could use to solve for the nth prime? Let $S$ and $T$ be finite non-empty sets such that $|S| = |T|$. Show that the function $f : S\to T$ is onto if and only if it is one-to-one. This is a recent homework bonus question assigned in my Proofs and Conjectures class. It (evidently) includes and evaluates our understanding of elementary-set theory and how to determine and prove that the function f is onto and one-to-one. I haven't been able to really grasp firmly how it is we do this. Help would be much appreciate, thank you. What are the benefits of modeling in one piece, or as separate parts? Eclipse Scala IDE - class file needed by X is missing How to show that $\lim \frac{1}{n} \sum_{i=1}^n \frac{1}{i}=0 $? Show that  $$\lim \frac{1}{n} \sum_{i=1}^n \frac{1}{i} =0 $$  I've proved that this sequence converges (it is bounded and decreasing). NOW, I need to find a sequence that is bigger than this one and goes to zero. Maybe something using geometric serie of 1/2  Thanks in advance! How to Search for Files Recursively into Subdirectories I am trying to look for all XML files in a particular directory and all sub-directories (recursively) inside it.  ls -R *.xml is only listing files in the current directory. I am quite sure, the sub-folders themselves have several .xml files, but none are showing up.  Is this a configuration issue? Noun form of "affected", meaning things that are affected by X
