    All common sequences just use the parameters as a series of semicolon-separated numbers such as 1;2;3. [5]: 5.4.2 Missing numbers are treated as 0 (1;;3 acts like the middle number is 0, and no parameters at all in ESC[m acts like a 0 reset code). Some sequences (such as CUU) treat 0 as 1 in order to make missing parameters useful. [5]: F.4.2

    Mobile Information Device Profile (MIDP) is a specification published for the use of Java on embedded devices such as mobile phones and PDAs.MIDP is part of the Java Platform, Micro Edition (Java ME) framework and sits on top of Connected Limited Device Configuration (CLDC), a set of lower level programming interfaces.

    en.wikipedia.org/wiki/Double-checked_locking

    The original form of the pattern, appearing in Pattern Languages of Program Design 3, [2] has data races, depending on the memory model in use, and it is hard to get right. Some consider it to be an anti-pattern. [3] There are valid forms of the pattern, including the use of the volatile keyword in Java and explicit memory barriers in C++. [4]

  6. Scratchpad memory - Wikipedia

    en.wikipedia.org/wiki/Scratchpad_memory

    [3] [4] [5] Many other processors allow L1 cache lines to be locked. Most digital signal processors use a scratchpad. Many past 3D accelerators and game consoles (including the PS2) have used DSPs for vertex transformations. This differs from the stream-based approach of modern GPUs which have more in common with a CPU cache's functions.

    Build a vector the same length as R with 1 in each place where the corresponding number in R is in the outer product matrix (∈, set inclusion or element of or Epsilon operator), i.e., 0 0 1 0 1 Logically negate ( not ) values in the vector (change zeros to ones and ones to zeros) ( ∼ , logical not or Tilde operator), i.e., 1 1 0 1 0

    en.wikipedia.org/wiki/Non-blocking_I/O_(Java)

    java.nio (NIO stands for New Input/Output [1] [2]) is a collection of Java programming language APIs that offer features for intensive I/O operations. It was introduced with the J2SE 1.4 release of Java by Sun Microsystems to complement an existing standard I/O. NIO was developed under the Java Community Process as JSR 51. [3]

  9. Primitive wrapper class in Java - Wikipedia

    en.wikipedia.org/.../Primitive_wrapper_class_in_Java

    With Java 5.0, additional wrapper classes were introduced in the java.util.concurrent.atomic package. These classes are mutable and cannot be used as a replacement for the regular wrapper classes. Instead, they provide atomic operations for addition, increment and assignment. The atomic wrapper classes and their corresponding types are:
