Nginx configuration to detect request from mobile user-agent and redirect them to mobile site. location / { #mobile site handling as per user agent set $mobile_rewrite do_not_perform; // variable to store action. default set to not perform redirection to mobile site. if ($htt...
Define the variables within a formula field: Shared NumberVar x := 1000; Shared NumberVar y; Assigning the values is optional. To display the variable in a second formula later on in the report, the call is nearly identical: Shared NumberVar x; x
Ucto is a rule-based tokeniser for multiple languages. It does sentence boundary detection as well. Although it is written in C++, there is a Python binding python-ucto to interface with it. import ucto #Set a file to use as tokeniser rules, this one is for English, other languages are availabl...
In many application it is necessary to compute the function of two or more arguments. Traditionally, we use for-loops. For example, if we need to calculate the f = exp(-x^2-y^2) (do not use this if you need fast simulations): % code1 x = -1.2:0.2:1.4; y = -2:0.25:3; for nx=1:lenght(x) for n...
Custom matchers can be added in jasmine using the syntax: jasmine.addMatchers([ toMatch: function () { return { compare: function (actual, expected) { return { pass: actual===expected, message: "Expected actual to match expected...
Protractor can selectively run groups of tests using fdescribe() instead of describe(). fdescribe('first group',()=>{ it('only this test will run',()=>{ //code that will run }); }); describe('second group',()=>{ it('this code will not run',()=>{ //code...
Protractor allows tests to be set as pending. This means that protractor will not execute the test, but will instead output: Pending: 1) Test Name Temporarily disabled with xit Or, if disabled with xdescribe(): Pending: 1) Test Name No reason given Combinations A xit() within an xdesc...
A TypeScript function can take in parameters of multiple, predefined types using union types. function whatTime(hour:number|string, minute:number|string):string{ return hour+':'+minute; } whatTime(1,30) //'1:30' whatTime('1',30) //'1:30' whatTime(1,'30') //'1:30' wha...
Custom matchers will have their pass value negated when using 'not'. Custom matchers can have a negative compare attribute to explicitly handle cases where their negation is desired: toMatch: function () { return { compare: function (actual, expected) { return...
Time complexity is a property of Problems someone might want to solve computationally, Algorithms designed to solve such problems and Programs implementing such algorithms. An abstract concept requires no installation or setup. Simply take any problem, algorithm, or code and ask "How lo...
This uses the Dropbox Java SDK to download a file from the Dropbox API at the remote path /Homework/math/Prime_Numbers.txt to the local file Prime_Numbers.txt: String localPath = "Prime_Numbers.txt"; OutputStream outputStream = new FileOutputStream(localPath); FileMetadata metadata = cl...
Many real-world database tables have many rows with DATETIME OR TIMESTAMP column values spanning a lot of time, including years or even decades. Often it's necessary to use a WHERE clause to retrieve some subset of that timespan. For example, we might want to retrieve rows for the date 1-September-2...
Doubly Linked Lists are a type of linked list. A doubly linked list's nodes have two "pointers" to other nodes, "next" and "previous." It is called a double linked list because each node only has two "pointers" to other nodes. A doubly linked list may have a h...

There is a dozen implementations of Standard ML. MLton produces very optimized code, but has no REPL. SML/NJ is the most widely used, but has slightly difficult error messages for learning purposes. Moscow ML and Poly/ML are easy to get started with, but don't support the .mlb package format. That i...
Joins in Spark: Read textFile 1 val txt1=sc.textFile(path="/path/to/input/file1") Eg: A B 1 2 3 4 Read textFile 2 val txt2=sc.textFile(path="/path/to/input/file2") Eg: A C 1 5 3 6 Join and print the result. txt1.join(txt2).foreach(p...
Two of the most fundamental higher-order functions included in the standard library are map and filter. These functions are generic and can operate on any iterable. In particular, they are well-suited for computations on arrays. Suppose we have a dataset of schools. Each school teaches a particular...
You can use the IFA for measuring ad clicks and the IFV for measuring app installs. IFA has built-in privacy mechanisms that make it perfect for advertising. In contrast, the IFV is for developers to use internally to measure users who install their apps. IFA ASIdentifierManager class pr...
A lot of example code posted on StackOverflow includes snippets like this: if ("A".equals(someString)) { // do something } This does "prevent" or "avoid" a possible NullPointerException in the case that someString is null. Furthermore, it is arguable that ...
A bit-field is used to club together many variables into one object, similar to a structure. This allows for reduced memory usage and is especially useful in an embedded environment. e.g. consider the following variables having the ranges as given below. a --> range 0 - 3 b --> range 0 -...
