With an input password type, you can also enable an icon that can show or hide the entire text using the passwordToggleEnabled attribute. You can also customize same default using these attributes: passwordToggleDrawable: to change the default eye icon passwordToggleTint: to apply a tint to the...

Ω-notation is used for asymptotic lower bound. Formal definition Let f(n) and g(n) be two functions defined on the set of the positive real numbers. We write f(n) = Ω(g(n)) if there are positive constants c and n0 such that: 0 ≤ c g(n) ≤ f(n) for all n ≥ n0. Notes f(n) = Ω(g(n)) means that f(n)...

<<"Guten tag, Hello">> = iolist_to_binary(["Guten tag, ",<<"Hello">>]). An IO list can be converted to a binary using the iolist_to_binary/1 function. If the data is going to be stored for a long period or sent as a message to other processes ...

The following example uses allow and receive to stub a Cart's call to a CreditCardService so that the example doesn't have to wait for a network call or use a credit card number that the processor knows about. class Cart def check_out begin transaction_id = CreditCardService.instance...

Although Julia is not a purely functional language, it has full support for many of the cornerstones of functional programming: first-class functions, lexical scope, and closures. The fixed-point combinator is a key combinator in functional programming. Because Julia has eager evaluation semantics ...

The SKI combinator system is sufficient to represent any lambda calculus terms. (In practice, of course, lambda abstractions blow up to exponential size when they are translated into SKI.) Due to the simplicity of the system, implementing the S, K, and I combinators is extraordinarily simple: A Dir...

You can bind event listeners to the EventSource object to listen to different events channels using the .addEventListener method. EventSource.addEventListener(name: String, callback: Function, [options]) name: The name related to the name of the channel the server is emitting events to. callb...

All of the logical operators in VBA can be thought of as "overrides" of the bitwise operators of the same name. Technically, they are always treated as bitwise operators. All of the comparison operators in VBA return a Boolean, which will always have none of its bits set (False) or all of...

Most of linux distros stores its version info in the /etc/lsb-release (debian) or /etc/redhat-release (RPM based) file. Using below generic command should get you past most of the Debian and RPM derivatives as Linux Mint and Cent-Os. Example on Ubuntu Machine: cat /etc/*release DISTRIB_ID=Ubuntu ...

Don't want your columns to simply stack in smaller devices? Use the extra small and medium device grid classes by adding .col-xs-* .col-md-* to your columns. See the example below for a better idea of how it all works. <!-- Stack the columns on mobile by making one full-width and the other half-...

Build on the previous example by creating even more dynamic and powerful layouts with tablet .col-sm-* classes. <div class="row"> <div class="col-xs-12 col-sm-6 col-md-8">.col-xs-12 .col-sm-6 .col-md-8</div> <div class="col-xs-6 col-md-4">...
