Outlook can sometimes add a bit of spacing on the left and right side of a element that can cause some layout-related headaches. By using the vendor-specific mso-table-lspace and mso-table-rspace CSS properties, you can be rid of those spaces and continue on to tackle the million other problems cau...
Sometimes we want to look at what is sent and received in the SOAP request. The following methods will return the XML in the request and response:
SoapClient::__getLastRequest()
SoapClient::__getLastRequestHeaders()
SoapClient::__getLastResponse()
SoapClient::__getLastResponseHeaders()
For ex...
Single characters can be extracted using array (square brace) syntax as well as curly brace syntax. These two syntaxes will only return a single character from the string. If more than one character is needed, a function will be required, i.e.- substr
Strings, like everything in PHP, are 0-indexed....
This snippet is an helper function to enumerate all files older than a specified age, it's useful - for example - when you have to delete old log files or old cached data.

To use opacity in all versions of IE, the order is:
.transparent-element {
/* for IE 8 & 9 */
-ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=60)"; // IE8
/* works in IE 8 & 9 too, but also 5, 6, 7 */
filter: alpha(opacity=60); // IE 5-7
/* Modern Browse...

It may become necessary to traverse the elements of a series or the rows of a dataframe in a way that the next element or next row is dependent on the previously selected element or row. This is called path dependency.
Consider the following time series s with irregular frequency.

The summation
1/1 + 1/2 + 1/3 + 1/4 + ... + 1/n
is equal to the nth harmonic number, denoted Hn. The nth harmonic number obeys the inequalities
ln (n + 1) ≤ Hn ≤ (ln n) + 1
and therefore Hn = Θ(log n). The harmonic numbers often arise in the analysis of algorithms, with randomized quicks...
The summation
1/1 + 1/4 + 1/9 + 1/16 + ...
out to infinity converges to π2 / 6, and therefore any summation of the form
1/1 + 1/4 + 1/9 + 1/16 + ... + 1/n2
is Θ(1).
To use additional packages within the Rcpp ecosystem, the correct header file may not be Rcpp.h but Rcpp<PACKAGE>.h (as e.g. for RcppArmadillo). It typically needs to be imported and then the dependency is stated within
// [[Rcpp::depends(Rcpp<PACKAGE>)]]
Examples:
// Use the RcppAr...
Most printable characters can be included in string or regular expression literals just as they are, e.g.
var str = "ポケモン"; // a valid string
var regExp = /[Α-Ωα-ω]/; // matches any Greek letter without diacritics
In order to add arbitrary characters to a string or regular expression,...
The Java language allows you to use new to create instances Integer, Boolean and so on, but it is generally a bad idea. It is better to either use autoboxing (Java 5 and later) or the valueOf method.
Integer i1 = new Integer(1); // BAD
Integer i2 = 2; // BEST (autoboxing)...
Using new String(String) to duplicate a string is inefficient and almost always unnecessary.
String objects are immutable, so there is no need to copy them to protect against changes.
In some older versions of Java, String objects can share backing arrays with other String objects. In those ver...
It is (almost always) a bad idea to call System.gc().
The javadoc for the gc() method specifies the following:
"Calling the gc method suggests that the Java Virtual Machine expend effort toward recycling unused objects in order to make the memory they currently occupy available for quick re...
Elm defines the following special type variables that have a particular meaning to the compiler:
comparable: Comprised of Int, Float, Char, String and tuples thereof. This allows the use of the < and > operators.
Example: You could define a function to find the smallest and largest eleme...
We can change the tasks execution order with the dependsOn method.
task A << {
println 'Hello from A'
}
task B(dependsOn: A) << {
println "Hello from B"
}
Adding `dependsOn: causes:
task B depends on task A
Gradle to execute A task everytime before the B ta...
project('projectA') {
task A(dependsOn: ':projectB:B') << {
println 'Hello from A'
}
}
project('projectB') {
task B << {
println 'Hello from B'
}
}
To refer to a task in another project, you prefix the name of the task with the path of the pr...
