Topic: Heap


  
  Don Markstein's Toonopedia: The Heap
The Heap was comics' very first shambling muck monster, tho he was undoubtedly inspired by Theodore Sturgeon's 1940 short story, "It", the template for all shambling muck monsters to come.
In The Heap's case, the man in the muck was Baron von Emmelmann, who had everything to live for — wealth, social position, loving wife, baby he hadn't yet seen, etc. — when, on October 12, 1918, his plane was shot down over Poland's Wausau Swamp.
This version of The Heap, which seems to have no connection at all to the original (instead of a German air ace, he's reconstructed from an American street derelict), has been used only as an occasional supporting character.

 Heap
A heap is a tree structure where the relationship is between the parent and its children.
Heaps will always have to be full trees -- that is, there must be no holes at any depth except for the greatest depth, and all of the holes at the greatest depth are to the right.
The tree we are left with is not a heap, because there is a hole on the bottom left of the tree.

In 2003 Heap parted ways with Island records, who released Frou Frou’s “Details”, though they were keen to put out the next solo album she felt it was “time for a change of scenery”.
The soundtrack to Heap’s cycle rides between her Waterloo home and her studio may partly explain the cross-pollination of genres that is ‘Speak For Yourself’.
Heap pauses for thought…“It’s quite tricky writing lyrics for “love” songs when you are happy and content with your man,” she laughs.

 Sorting revisited
Heap sort is based around the idea of arranging the elements into a "heap" which allows an O(1) algorithm for finding the maximum element and an O(ln(n)) for deleting it out of the array.
The operation of re-establishing the heap property of a heap after its maximum element is deleted (called sifting) is essentially a rotation of a sequence of sub-heap maximums.
This sift down operation is basically a loop which traverses the binary tree structure of the heap always chosing the node with the higher value and shuffling these nodes upward.

 How to use Pageheap.exe in Windows XP and Windows 2000
Corruptions in heap blocks are discovered by either placing a non-accessible page at the end of the allocation, or by checking fill patterns when the block is freed.
In order to be able to pinpoint failures, first use normal page heap to determine the range where a process is failing, and then use full-page heap on individual large-scale processes for that restricted class of allocations (that is, a specific size range or a specific library).
The Windows heap managers (all versions) have always guaranteed that the heap allocations have a start address that is 8-byte aligned (on 64-bit platforms the alignment is 16-bytes).

The record is the London-based Heap's second since leaving Frou Frou, the band she started with Guy Sigsworth.
Heap says Speak for Yourself gave her the chance to build on the things that first drew her to music as a child.
But even as she considers the musical legacy she received from her parents, Heap is very much her own singer -- from songwriting to technology, she has followed her own tastes in creating the new songs.

 heap - a definition from Whatis.com
In certain programming languages including C and Pascal, a heap is an area of pre-reserved computer main storage (memory) that a program process can use to store data in some variable amount that won't be known until the program is running.
Having a certain amount of heap storage already obtained from the operating system makes it easier for the process to manage storage and is generally faster than asking the operating system for storage every time it's needed.
A stack is similar to a heap except that the blocks are taken out of storage in a certain order and returned in the same way.

The heap dump is a dump of all the live objects and classes.
Heap dumps aren't very useful without a tool to read them but a novel tool called the Heap Analysis Tool (HAT), courtesy of Bill Foote, was released at around the same time.
To sum up: Mustang (Java SE 6.0) allows heap dumps to be obtained at out of memory time, at any time during the life time of the application, or even after an applications dies with a crash.

 Heap Sort
Remember that a heap is a way to implement a priority queue.
Since a heap has worst case complexity of O(log(n)) it can get O(nlog(n)) to remove n value that are sorted.
As with other heap operations, we first make it a complete binary tree and then fix up so the ordering is correct.

 Heap of Fish Java Applet - an Interactive Illustration of Garbage Collection
Heap of Fish has five modes, which can be selected via radio buttons at the bottom left of the applet.
The compact heap mode allows you to slide heap objects so that they are side by side at one end of the heap, leaving all free memory as one large contiguous block at the other end of the heap.
During the mark phase, the fish objects on the heap are traversed depth-first starting from the local variables.

 [No title]
"Memory that is dynamically allocated by the application is known as the heap." The words "by the application" are important here, as on good systems most areas are in fact dynamically allocated at the kernel level, while for the heap, the allocation is requested by the application.
Heap and Data/BSS Sections ~~~~~~~~~~~~~~~~~~~~~~~~~~ The heap is an area in memory that is dynamically allocated by the application.
heap offset method: offset from the top of the heap to the estimated address of the target/overflow buffer (requiring an executable heap) Note: There is a greater probability of the heap being executable than the stack on any given system.

 Chapter 18: Heap
A heap is a special kind of tree that happens to be an efficient implementation of a priority queue.
That implies that r is the largest value in the heap and that a and b are the largest values in their respective subtrees.
In both cases we keep examining levels of the tree until we restore the heap property, which means we might only visit one, or in the worst case we might have to visit them all.

 A new way to bypass Windows heap protections
Heap exploitation is now mastered for systems such as Windows XP, Windows XP SP1 and Windows 2000.
A heap is a collection of contiguous chunks of memory, as shown below in Figure 1.
This first public method to bypass the new heap protections consists of exploiting the inexistent checks on the lookaside list (refer to the paper, "Defeating Windows XP SP2 Heap protection and DEP bypass" [ref 4] if you want to learn more about lookaside lists).

 Java's garbage-collected heap - Java World
A more accurate and up-to-date metaphor might be "memory recycling." When an object is no longer referenced by the program, the heap space it occupies must be recycled so that the space is available for subsequent new objects.
New objects are allocated, and unreferenced objects are freed such that free blocks of heap memory are left in between blocks occupied by live objects.
Requests to allocate new objects may have to be filled by extending the size of the heap even though there is enough total unused space in the existing heap.

 IMOGEN HEAP   (Site not responding. Last check: )
Heap nestled into a decidedly unhip neighborhood in London's docklands and filled her studio with keyboards, two pianos, a Freakenspeak circuit-bent Speak & Spell and a small vocal booth outfitted with a Neumann TLM 103.
Although she usually deferred to East West Symphonic Gold Orchestra for virtual instruments, many of Heap's favorite sounds were simply those that were the most fun to play.
Heap's paradoxically free-spirited and rigidly structured approach to music writing often led her to use classic instruments in unorthodox ways: “The Moment I Said It” began as her attempt to build a song entirely from noises she picked up from her piano.

This module provides an implementation of the heap queue algorithm, also known as the priority queue algorithm.
The API below differs from textbook heap algorithms in two aspects: (a) We use zero-based indexing.
(b) Our pop method returns the smallest item, not the largest (called a "min heap" in textbooks; a "max heap" is more common in texts because of its suitability for in-place sorting).
