The tabular environment is the most basic way to create a table in LaTeX and doesn't require any other packages. \begin{tabular}{|lcr||} left aligned column & center column & right column \\ \hline text & text & text \\ text & text & text \\ \end{tabular} T...

The following C code uses the OpenMP parallel programming model to write the thread ID and number of threads to stdout using multiple threads. #include <omp.h> #include <stdio.h> int main () { #pragma omp parallel { // ID of the thread in the current team ...

The two mapAccum functions combine the operations of folding and mapping. -- A Traversable structure -- | -- A seed value | ...

A model can also be added to the partial view : @model Solution.Project.Namespace.MyModelClass <p>@Model.Property</p> In the View you can now just use: <div> @Html.Partial("PartialViewExample", new MyModelClass(){Property="my property value"}) <...

Charts can be created by working directly with the Series object that defines the chart data. In order to get to the Series without an exisitng chart, you create a ChartObject on a given Worksheet and then get the Chart object from it. The upside of working with the Series object is that you can s...

The starting point for the vast majority of charting code is to create an empty Chart. Note that this Chart is subject to the default chart template that is active and may not actually be empty (if the template has been modified). The key to the ChartObject is determining its location. The syntax...

For complete control over a new Chart and Series object (especially for a dynamic Series name), you must resort to modifying the SERIES formula directly. The process to set up the Range objects is straightforward and the main hurdle is simply the string building for the SERIES formula. The SERIES ...

A common chore with charts in Excel is standardizing the size and layout of multiple charts on a single sheet. If done manually, you can hold down ALT while resizing or moving the chart to "stick" to cell boundaries. This works for a couple charts, but a VBA approach is much simpler. Co...

Another feature of list comprehensions is guards, which also act as filters. Guards are Boolean expressions and appear on the right side of the bar in a list comprehension. Their most basic use is [x | p x] === if p x then [x] else [] Any variable used in a guard must appear on its left ...

With Parallel List Comprehensions language extension, [(x,y) | x <- xs | y <- ys] is equivalent to zip xs ys Example: [(x,y) | x <- [1,2,3] | y <- [10,20]] -- [(1,10),(2,20)]

Code snippet: import java.util.Set; public class ThreadStatus { public static void main(String args[]) throws Exception { for (int i = 0; i < 5; i++){ Thread t = new Thread(new MyThread()); t.setName("MyThread:" + i); t.start(); ...

Sometimes you need to fetch data asynchronously before passing it to a child component to use. If the child component tries to use the data before it has been received, it will throw an error. You can use ngOnChanges to detect changes in a components' @Inputs and wait until they are defined before a...

x = np.random.random([100,100]) x.tofile('/path/to/dir/saved_binary.npy') y = fromfile('/path/to/dir/saved_binary.npy') z = y.reshape(100,100) all(x==z) # Output: # True

Consider a grid working on some task, e.g. a parallel reduction. Initially, each block can do its work independently, producing some partial result. At the end however, the partial results need to be combined and merged together. A typical example is a reduction algorithm on a big data. A typica...

To start GDB, in the terminal, gdb <executable name> For the above example with a program named main, the command becomes gdb main Setting Breakpoints You'll probably want you program to stop at some point so that you can review the condition of your program. The line at which you wan...

Batch file command line arguments are parameter values submitted when starting the batch. They should be enclosed in quotes if they contain spaces. In a running batch file, the arguments are used for various purposes, i.e. redirection to :labels, setting variables, or running commands. The argument...

When more than 9 arguments are supplied, the shift [/n] command can be used, where /n means start at the nth argument, n is between zero and eight. Looping through arguments: :args set /a "i+=1" set arg!i!=%~1 call echo arg!i! = %%arg!i!%% shift goto :args Note, in the above exam...

Bottom sheets slide up from the bottom of the screen to reveal more content. They were added to the Android Support Library in v25.1.0 version and supports above all the versions. Make sure the following dependency is added to your app's build.gradle file under dependencies: compile 'com.android...

When multiple variables are defined at the beginning of the batch, a short definition form may be used by employing a replacement string. @echo off set "vars=_A=good,_B=,_E=bad,_F=,_G=ugly,_C=,_H=,_I=,_J=,_K=,_L=,_D=6 set "%vars:,=" & set "%" for /f %%l in ('set _'...

There are two approaches for influencing when a memory cleanup is performed. They are influencing how often the automatic process is performed and the other is manually triggering a cleanup. The garbage collector can be manipulated by tuning the collection thresholds which affect the frequency at w...
