Objects is adapted from the 2006 novel by Gone Girl author Gillian Flynn and directed by Jean-Marc Vallée, the man responsible for Big Little Lies, and once again he creates a sense of tantalizingly ambiguous indirection, as well as repressed psychological forces that seep and spread like a stain across a plaster ceiling.
But to suggest by coy indirection ("Poor Sophie Portnoy") that he is among those Jewish writers and comics who worked the theme of the overbearing Jewish mother because they were (if, indeed, any of them were; how does she know?) "desperate to assimilate into mainstream society and spewed their mommy issues across the page, stage and screen" — what a dimwitted insult to a giant.
Of course, due to Pettibon's staggering prolificacy (Gioni remarked that these 900 items were chosen from 5,000 out of a potential pool of 20,000), it is impossible to state anything with assurance, but the retro aspect of Kennedy, Manson, Hearst, and Gumby, to name a few, implies that a significant degree of historical distance is required for the kind of indirection we encounter in the most effective pieces on display.
The album's glitchy loudness and restless indirection most directly simulate the horrors of the internet — the way social media kills the attention span as countless incompatible stimuli blare at you, but also the way one tangential distraction can lead to another until you don't know where you are or how you got there, stranded in some dark online corner where strangers are selling exotic animals or debating Star Wars fan conspiracy theories.

In computer programming, indirection (also called dereferencing) is the ability to reference something using a name, reference, or container instead of the value itself. The most common form of indirection is the act of manipulating a value through its memory address. For example, accessing a variable through the use of a pointer. A stored pointer that exists to provide a reference to an object by double indirection is called an indirection node.
A famous aphorism of David Wheeler goes: "All problems in computer science can be solved by another level of indirection" (the "fundamental theorem of software engineering"). This is often deliberately mis-quoted with "abstraction layer" substituted for "level of indirection". An often cited corollary to this is, "...except for the problem of too many layers of indirection." A humorous Internet memorandum, , insists that: Object-oriented programming makes use of indirection extensively, a simple example being dynamic dispatch.
Higher-level examples of indirection are the design patterns of the proxy and the proxy server. Delegation is another classic example of an indirection pattern. In strongly typed interpreted languages with dynamic datatypes, most variable references require a level of indirection: first the type of the variable is checked for safety, and then the pointer to the actual value is dereferenced and acted on. Recursive data types are usually implemented using indirection, because otherwise if a value of a datatype can contain the entirety of another value of the same datatype, there is no limit to the size a value of this datatype could need.
This level of indirection is what makes function objects an excellent technology for achieving loosely coupled programs.
For address generation, indexing, if specified, is performed before indirection. The word at the effective indirect address is decoded as if it were an instruction (except that the instruction code is ignored), allowing an indirect address to also specify indirection or indexing. Multiple levels of indirect addressing are allowed.
Because Java lacks value types, this array is actually an array of references (pointers) to `Entry` objects, which in turn contains references to key and value objects. Looking up something in the map requires inefficient double indirection. If `Entry` were a value type, the array could store pairs of key and value references directly, eliminating the first indirection, increasing locality and reducing memory usage and heap fragmentation. If Java further supported generic primitive types, primitive keys and values could be stored in the array directly, removing the second indirection.
"Bounded" indirection will not allow us to compute the partial recursive functionsfor those we need unbounded indirection aka the μ operator. :Suppose we had been able to continue on to number 65367, and in fact that register had what we were looking for. Then we could have completed our calculation successfully! But suppose 65367 didn't have what we needed.
The OSI model comprises seven abstraction layers. Each layer of the model encapsulates and addresses a different part of the needs of digital communications, thereby reducing the complexity of the associated engineering solutions. A famous aphorism of David Wheeler is "All problems in computer science can be solved by another level of indirection". This is often deliberately misquoted with "abstraction" substituted for "indirection".
The color indirection flexibility allows a program to tailor the screen's colors to fit the purpose of the program's display. All hardware color registers have corresponding shadow registers.
He also wrote Ye Qine Wubet (The Beauty of Qəne) in which he proved his command of the unique Ethiopian literary tradition of qəne (ቅኔ), a form of linguistic indirection and play.
All Player/Missile objects' pixels and all Playfield pixels in the default CTIA/GTIA color interpretation mode use indirection to specify color. Indirection means that the values of the pixel data do not directly specify the color, but point to another source of information for color. CTIA/GTIA contain hardware registers that set the values used for colors, and the pixels' information refer to these registers. The palette on the Atari is 8 luminance levels of 16 colors for a total 128 colors.
Access to a data record requires two levels of indirection, where the file's directory entry (called a File Status Table (FST) entry) points to blocks containing a list of addresses of the individual records.
Lampson is often quoted as saying, "Any problem in computer science can be solved with another level of indirection," but in his Turing Award Lecture in 1993, Lampson himself attributes this saying to David Wheeler.
Artists such as Ingmar Bergman, Pablo Picasso, and Bob Dylan answered questions about their work for years, but their answers tended to come down as rock slides of near gibberish: unsolid, unhelpful, and full of indirection.
Memory access patterns are much more predictable. While arrays do exist, their dimension is fixed at kernel invocation. The thing which most closely matches a multiple pointer indirection is an indirection chain, which is however guaranteed to finally read or write from a specific memory area (inside a stream). Because of the SIMD nature of the stream processor's execution units (ALUs clusters), read/write operations are expected to happen in bulk, so memories are optimized for high bandwidth rather than low latency (this is a difference from Rambus and DDR SDRAM, for example).
Martin Richards, creator of the BCPL language (a precursor of C), designed arrays initiating at 0 as the natural position to start accessing the array contents in the language, since the value of a pointer p used as an address accesses the position p + 0 in memory. Canadian systems analyst Mike Hoye asked Richards the reasons for choosing that convention. BCPL was first compiled for the IBM 7094; the language introduced no indirection lookups at run time, so the indirection optimization provided by these arrays was used at compile time. The optimization was nevertheless important.
Consequently, these files provide a convenient level of indirection. Additionally, the dialog box specifies a number of alternate OLE DB data providers for a variety of target applications.MSDN, "Creating a udl file", "ADO 2.8 API Reference", accessed April 28, 2007.
If we eschew the Minsky approach of one monster number in one register, and specify that our machine model will be "like a computer" we have to confront this problem of indirection if we are to compute the recursive functions (also called the μ-recursive functions )both total and partial varieties. Our simpler counter-machine model can do a "bounded" form of indirectionand thereby compute the sub-class of primitive recursive functionsby using a primitive recursive "operator" called "definition by cases" (defined in Kleene (1952) p. 229 and Boolos-Burgess-Jeffrey p. 74). Such a "bounded indirection" is a laborious, tedious affair.
The exceptions are symbols and contexts, which are shared instead of copied, and thus can be used for indirection. Symbols and contexts are globally named and are deleted explicitly; deleting a symbol or context scans all other objects to replace references to it with `nil`.
This level of indirection allows for pre and post operations relative to the abstract operations both immediately and with future unforeseen changes. The NVI pattern can be deployed with very little software production and runtime cost. Many commercial software frameworks employ the NVI pattern.
How to de-couple objects so that low coupling is supported and reuse potential remains higher? Solution: Assign the responsibility to an intermediate object to mediate between other components or services so that they are not directly coupled. The intermediary creates an indirection between the other components.
Andrew Gerrand, Go Slices: usage and internals.The Go Authors, Effective Go: Slices. Pointers are available for all types, and the pointer-to- type is denoted . Address-taking and indirection use the and operators, as in C, or happen implicitly through the method call or attribute access syntax.
Cook and Reckhow (1973) cite Hartmanis (1971) and simplify his model to what they call a random-access machine (RAM—i.e. a machine with indirection and the Harvard architecture). In a sense we are back to Melzak (1961) but with a much simpler model than Melzak's.
Although drawing commands have to be re-issued for each new frame, modern systems using this method are generally able to avoid the unnecessary duplication of more memory-intensive display data by referring to that unchanging data (via indirection) (e.g. textures and vertex buffers) in the drawing commands.
If the word size is larger than the address, then the word referenced for memory-indirect addressing could itself have an indirect flag set to indicate another memory indirect cycle. This flag is referred to as an indirection bit, and the resulting pointer is a tagged pointer, the indirection bit tagging whether it is a direct pointer or an indirect pointer. Care is needed to ensure that a chain of indirect addresses does not refer to itself; if it does, one can get an infinite loop while trying to resolve an address. The IBM 1620, the Data General Nova, the HP 2100 series, and the NAR 2 each have such a multi-level memory indirect, and could enter such an infinite address calculation loop.
It differs from psychopathy in that the adroitness is not intrinsically narcissistic or manipulative, but refers rather to the set of social skills that allow one to work with others productively. In that sense it is closely related to conceptions of emotional intelligence. Tools of adroit behavior include flattery, indirection, listening, circumspection, reciprocal altruism, politeness and strategic reasoning.
Dependency Walker has not been updated to handle this layer of indirection gracefully, and when used on Windows 7 and later it will likely show multiple errors. Dependency Walker can still be used for some application level debugging despite this. As of October 2017 an Open Source C# rewrite of Dependency Walker called Dependencies.exe has been released on GitHub.
Ben-Dov has published books, articles, and essays on S. Y. Agnon, Abraham B. Yehoshua, Amos Oz, S. Yizhar, Yehuda Amichai, Yehoshua Kenaz, Yehudit Handel, Haim Be'er, Sami Michael, Zeruya Shalev, Yehudit Rotem, and Dahlia Ravikovitch. Her research combines structuralist, feminist, psychoanalytical, and biographical elements in the work of these authors, along with intra-textual and inter-textual scrutiny. Her book Agnon's Art of Indirection: Uncovering Latent Content in the Fiction of S.Y Agnon, published in 1993, revealed the possibility of analyzing Agnon's work (characterized by "the art of indirection", a term coined by Ben-Dov) even when translated into English. Ben-Dov has introduced Agnon to scholars of literature outside Israel and proved that it is possible to analyze word by word, through close reading, the unique nature of Agnon's work.
More generally, a pointer is a kind of reference, and it is said that a pointer references a datum stored somewhere in memory; to obtain that datum is to dereference the pointer. The feature that separates pointers from other kinds of reference is that a pointer's value is meant to be interpreted as a memory address, which is a rather low-level concept. References serve as a level of indirection: A pointer's value determines which memory address (that is, which datum) is to be used in a calculation. Because indirection is a fundamental aspect of algorithms, pointers are often expressed as a fundamental data type in programming languages; in statically (or strongly) typed programming languages, the type of a pointer determines the type of the datum to which the pointer points.
At least two reasons: (1) An instruction set with no parameters: Schönhage does this to produce his RAM0 instruction set. See section below. (2) Reduce a RAM to a Post-Turing machine: Posing as minimalists, we reduce all the registers excepting the accumulator A and indirection register N e.g. r = { r0, r1, r2, ... } to an unbounded string of (very-) bounded-capacity pigeon-holes.
From John Siracusa: > Back in 1984, explanations of the original Mac interface to users who had > never seen a GUI before inevitably included an explanation of icons that > went something like this: "This icon represents your file on disk." But to > the surprise of many, users very quickly discarded any semblance of > indirection. This icon is my file. My file is this icon.
The mismatch between BCPL's word orientation and byte-oriented hardware was addressed in several ways. One was by providing standard library routines for packing and unpacking words into byte strings. Later, two language features were added: the bit-field selection operator and the infix byte indirection operator (denoted by `%`). BCPL handles bindings spanning separate compilation units in a unique way.
Other languages often use substantially similar syntax, but details of syntax and actual functionality can vary significantly. When used simply for string literals, the `<<` does not indicate indirection, but is simply a starting delimiter convention. In some languages, such as Ruby, `<<` is also used for input redirection, thus resulting in `<<` being used twice if one wishes to redirect from a here document string literal.
The SHAPE class has the basis (e.g. drawing data) for what is drawn, perhaps on a SURFACE, but it does not have to be. Again, the agents provide the indirection and class agnostics required to make the co-variant relationship with SHAPE as decoupled as possible. Additionally, please take note of the fact that SHAPE only provides `drawing_data_agent' as a fully exported feature to any client.
This solution works well until you run out of these dummies -- and you do not want to add too many because it takes up memory. Objective-C 2.0 provides non-fragile instance variables by having an extra level of indirection for instance variable access. Another partial solution is to use the Bridge pattern, sometimes known as "Pimpl" ("Pointer to implementation"). The Qt framework is an example of such an implementation.
Stoica was born and raised in Romania and educated at the Polytechnic University of Bucharest, graduating with a Master of Science degree in Electrical Engineering and Computer Science, 1989. He went on to study at Carnegie Mellon University (CMU) gaining a Ph.D. in Electrical & Computer Engineering in 2000 supervised by Hui Zhang. Subjects included Chord (peer-to-peer), Core-Stateless Fair Queueing (CSFQ), and Internet Indirection Infrastructure (i3).
In the worst case, Timsort takes O(n \log n) comparisons to sort an array of elements. In the best case, which occurs when the input is already sorted, it runs in linear time, meaning that it is an adaptive sorting algorithm. It is advantageous over Quicksort for sorting object references or pointers because these require expensive memory indirection to access data and perform comparisons and Quicksort's cache coherence benefits are greatly reduced.
At update time, this indirection is updated to point to the newest version. If a DSU system does not use a compiler to insert these indirections statically, it insert them at runtime with binary rewriting. Binary rewriting is the process of writing low-level code into the memory image of a running native program to re-direct functions. While this requires no static analysis of a program, it is highly platform- dependent.
For this reason and because POSIX does not standardize path names, POSIX does not standardize the feature. Often, the program can be used to circumvent this limitation by introducing a level of indirection. is followed by , followed by the desired command without full path, as in this example: #!/usr/bin/env sh This mostly works because the path is commonly used for the utility, and it invokes the first found in the user's $PATH, typically .
Indirection is a technique used in data structures in which a problem is split into multiple levels of a data structure in order to improve efficiency. Typically, a problem of size n is split into n/\log n problems of size \log n. For example, this technique is used in y-fast tries. This strategy also works to improve the insertion and deletion performance of the data structure described above to constant amortized time.
In fact, this strategy works for any solution of the list-labeling problem with O(\log n) amortized insertion and deletion time. The order-maintenance data structure with indirection. The total order elements are stored in O(N/\log N) contiguous sublists of size O(\log N), each of which has a representative in the scapegoat tree. The new data structure is completely rebuilt whenever it grows too large or too small.
By 1971 Hartmanis has simplified the indexing to indirection for use in his RASP model. Indirect addressing: A pointer-register supplies the finite state machine with the address of the target register required for the instruction. Said another way: The contents of the pointer- register is the address of the "target" register to be used by the instruction. If the pointer-register is unbounded, the RAM, and a suitable RASP built on its chassis, will be Turing equivalent.
A computer program can access an address given explicitly' – in low-level programming this is usually called an ', or sometimes a specific address, and is known as pointer data type in higher-level languages. But a program can also use relative address which specifies a location in relation to somewhere else (the base address). There are many more addressing modes. Mapping logical addresses to physical and virtual memory also adds several levels of indirection; see below.
Prêt à Voter was inspired by the earlier, voter- verifiable scheme by David Chaum. It replaces the visual cryptographic encoding the voter's choice in Chaum's scheme by the conceptually and technologically simpler candidate randomization. The Prêt à Voter idea of encoding the vote through permutations has subsequently been incorporated in Chaum's Punchscan scheme. However Punchscan uses a permutation of indirection symbols instead of candidate names allowing it to comply with voting laws that require a specific ordering of candidates.
Hooksafe is a hypervisor-based lightweight system that protects a operating system's kernel hooks from rootkit attacks. It prevents thousands of kernel hooks in the guest operating system from being hijacked. This is achieved by making a shadow copy of all the kernel hooks at one central place and adding an indirection layer on it to regulate attempts to access the hooks. A prototype of Hooksafe was used on a Linux guest and protected nearly 6000 kernel hooks.
Therefore, EABIs omit most abstractions that are made between kernel and user code in complex operating systems. For example, dynamic linking may be avoided to allow smaller executables and faster loading, fixed register usage allows more compact stacks and kernel calls, and running the application in privileged mode allows direct access to custom hardware operation without the indirection of calling a device driver. The choice of EABI can affect performance. Widely used EABIs include PowerPC, Arm EABI and MIPS EABI.
Since the machine had only 4kiB (4096 bytes) of RAM, this left very little room for program functions such as keeping score and game options. The rest of the program would have to be placed in ROM. The Astrocade used color registers, or color indirection, so the four colors could be picked from a palette of 256 colors. Color animation was possible by changing the values of the registers, and using a horizontal blank interrupt they could be changed from line to line.
Critiques of "Just a Girl" during its release era were positive. Mike Boehm wrote in the Los Angeles Times that Stefani's lyrics of "irony and indirection" make the serious subject matter of "Just a Girl" more appealing to the listener. In addition to several other tracks from Tragic Kingdom, Nick Levine from Noisey praised "Just a Girl" for having a chorus "that will bounce round your brain for days". Contemporary critics described "Just a Girl" as No Doubt's breakthrough single.
In 1989, she began to teach Hebrew and Comparative Literature at the University of Haifa, becoming a full professor in 1999. She has served as Editor-in-Chief of Haifa University Press/Zmora-Bitan (1996–2000) and as chair of the Academic TV channel (2001–2005). Ben-Dov is married to Yosi Ben-Dov, the principal and Managing Director of the Hebrew Reali School in Haifa, and they have three children.Agnon's Art of Indirection: Uncovering Latent Content in the Fiction of S.Y. Agnon.
The conserver was written to be used with RS-232 serial wired multi-port cards. Modern day setups (generally) use separate management Ethernet networks and console servers. In some cases some form of reverse telnet or SSH connection is used; alternatively, an additional level of indirection can be interposed: the server provides a Serial over LAN service via IPMI, and a command-line utility connects to the server. This socket can then be used as a "virtual reverse telnet" connection.
If our model has an unbounded accumulator can we bound all the other registers? Not until we provide for at least one unbounded register from which we derive our indirect addresses. The minimimalist approach is to use itself (Schönhage does this). Another approach (Schönhage does this too) is to declare a specific register the "indirect address register" and confine indirection relative to this register (Schonhage's RAM0 model uses both A and N registers for indirect as well as direct instructions).
The Fabian strategy is a military strategy where pitched battles and frontal assaults are avoided in favor of wearing down an opponent through a war of attrition and indirection. While avoiding decisive battles, the side employing this strategy harasses its enemy through skirmishes to cause attrition, disrupt supply and affect morale. Employment of this strategy implies that the side adopting this strategy believes time is on its side, but it may also be adopted when no feasible alternative strategy can be devised.
In order to achieve flexibility, design patterns usually introduce additional levels of indirection, which in some cases may complicate the resulting designs and hurt application performance. By definition, a pattern must be programmed anew into each application that uses it. Since some authors see this as a step backward from software reuse as provided by components, researchers have worked to turn patterns into components. Meyer and Arnout were able to provide full or partial componentization of two-thirds of the patterns they attempted.
After Pearl Harbor, Oboler's anti-Fascist plays – once shunned by corporate radio sponsors – were in demand. Oboler's new series was titled Plays For Americans; its purpose was to "stimulate the American people to the importance of the war effort by indirection rather than by direct appeal." Oboler's Plays For Americans was World War II propaganda in half-hour radio drama form, each story teaching a lesson about wartime responsibility. Oboler's shows for this series were as star-studded as his last series.
In principle the database storage can be viewed as a linear address space, where every bit of data has its unique address in this address space. In practice, only a very small percentage of addresses are kept as initial reference points (which also requires storage); most data is accessed by indirection using displacement calculations (distance in bits from the reference points) and data structures which define access paths (using pointers) to all needed data in an effective manner, optimized for the needed data access operations.
In 1873, he delivered a poem before the Society of the Army of the Cumberland and in 1874 wrote one for the Society of the Army of the Potomac. He was a described as a brilliant talker and a fine orator. Among his lectures were "Battle-Flashes" and "The Unwritten Story of the Martyr of Harpers Ferry". His most admired poems are "My Slain", "An Old Man's Idyll", "Indirection", and the verses that he wrote just before he took the poison that ended his life.
The song that Couse didn't write is John Cale's "(I Keep a) Close Watch" (listed as "Close Watch" on Genes), which addresses the fear of loss associated with love. This song is for many the highlight of the record, perhaps because the indirection of a cover performance helped Couse in the face of his grief over his father coupled with the apprehension of becoming a father himself. John Cale and The Velvet Underground are also significant musical influences on Couse.Couse cites Cale, The Velvet Underground, and Lou Reed as influences on his myspace page.
Seen in context, Ban Gu's discussion of Qu Yuan and the Chu sao style is less to the point of the actual evolutionary path of the fu and more to the point that the main purpose of the fu is political and social criticism through poetic indirection: thus, in fu, paradoxically, the "fantastic descriptions and an overflowing rhetoric...can be reduced to...restraint", as the sociopolitical criticism which was key to the fu was constrained within a very subtle, elaborately indirect, occasional, and allusive mode.Wilhelm (1967 [1957]): 312–314, quoting Sima Qian on Sima Xiangru.
This allows every program to behave as if it is the only one (apart from the kernel) running and thus prevents applications from crashing each other.Silberschatz 1991 On many systems, a program's virtual address may refer to data which is not currently in memory. The layer of indirection provided by virtual addressing allows the operating system to use other data stores, like a hard drive, to store what would otherwise have to remain in main memory (RAM). As a result, operating systems can allow programs to use more memory than the system has physically available.
Seen in context, Ban Gu's discussion of Qu Yuan and the Chu sao style is less to the point of the actual evolutionary path of the fu and more to the point that the main purpose of the fu is political and social criticism through poetic indirection: thus, in fu, paradoxically, the "fantastic descriptions and an overflowing rhetoric...can be reduced to...restraint", as the sociopolitical criticism which was key to the fu was constrained within a very subtle, elaborately indirect, occasional, and allusive mode.Wilhelm (1967 [1957]): 312–314, quoting Sima Qian on Sima Xiangru.
Most DSU systems use subroutines as the unit of code for updates; however, newer DSU systems implement whole- program updates. If the target program is implemented in a virtual machine language, the VM can use existing infrastructure to load new code, since modern virtual machines support runtime loading for other use cases besides DSU (mainly debugging). The HotSpot JVM supports runtime code loading, and DSU systems targeting Java (programming language) can utilize this feature. In native languages such as C or C++, DSU systems can use specialized compilers that insert indirection into the program.
Ginseng is a general-purpose DSU system. It is the only DSU system to use the cons-freeness safety technique, allowing it to update functions that are live on the stack as long as they do not make concrete accesses to updated types. Ginseng is implemented as a source-to-source compiler written using the C Intermediate Language framework in OCaml. This compiler inserts indirection to all function calls and type accesses, enabling Ginseng to lazily transform state at the cost of imposing a constant-time overhead for the entirety of the program execution.
The new addressing modes added scaled indexing and another level of indirection to many of the pre-existing modes, and added quite a bit of flexibility to various indexing modes and operations. Though it was not intended, these new modes made the 68020 very suitable for page printing; most laser printers in the early 1990s had a 68EC020 at their core. The 68020 had a small 256-byte direct-mapped instruction cache, arranged as 64 four-byte entries. Although small, it still made a significant difference in the performance of many applications.
Adding another level of indirection makes page table "walks" longer. A page table walk occurs when either the processor's memory management unit or the memory management code in the operating system navigates the tree of page tables to find the page table entry corresponding to a virtual address. This means that, in the worst case, the processor or the memory manager has to access physical memory six times for a single virtual memory access, rather than five for the previous iteration of x86-64 processors. This results in slightly reduced memory access speed.
" Lyons calls the book a "superior entertainment" and remarks that "Deighton seeks a literate audience" but that protagonist Patrick Armstrong "display[s] only the vestigial personal memory needed to flesh him out, so that he may neither learn significantly from previous adventures, nor (God forbid) intellectualize overmuch." However Pearl K. Bell writing in The New Leader called the book "an impenetrable lemon". "The artful fuzziness so completely overwhelmed the plot that the book was unreadable, all murk and no menace." Bell said that "evasive indirection has been Deighton's trademark since his first spy novel, The Ipcress File, appeared in 1963.
In computer science, a tagged pointer is a pointer (concretely a memory address) with additional data associated with it, such as an indirection bit or reference count. This additional data is often "folded" into the pointer, meaning stored inline in the data representing the address, taking advantage of certain properties of memory addressing. The name comes from "tagged architecture" systems, which reserved bits at the hardware level to indicate the significance of each word; the additional data is called a "tag" or "tags", though strictly speaking "tag" refers to data specifying a type, not other data; however, the usage "tagged pointer" is ubiquitous.
Malinche was in the middle of this event, translating the conversation between Cortés and Moctezuma. Gomara writes that Moctezuma was "speaking through Malinche and Aguilar", although other records indicate that Malinche was already translating directly, as she had quickly learned some Spanish herself. Moctezuma's flowery speech delivered through Malinche at the meeting has been claimed by the Spaniards to represent a submission, but this interpretation is not followed by modern historians. The deferential nature of the speech can be explained by Moctezuma's usage of , a Nahuatl register known for its indirection and complex set of reverential affixes.
Weden v. San Juan County, 135 Wn.2d 678, 725 (1998). He is often cited for his criticism of the progressive era and expansive interpretation of state "police powers": > Laws have been passed in one state and another abridging the right of > contract, the right to sell merchandise, the right to labor upon public > works, the right to labor more than a certain number of hours, the right to > freely come and go, the right to pursue legitimate trades, and a mass of > others. Some of these laws go directly to the point, but the majority > proceed by indirection.
Lubbock reviewed, anonymously in the columns of the Times Literary Supplement, some significant modern novels, including Forster's Howards End. His 1921 book The Craft of Fiction ("the official textbook of the Modernist aesthetics of indirection")José Ángel García Landa, Theory of reflexive fiction, Universidad de Zaragoza became a straw man for writers including Forster, Virginia Woolf and Graham Greene, who disagreed with his rather formalist view of the novel. Wayne Booth in The Rhetoric of FictionP. 24. considers that Lubbock's take on the craft of Henry James was in fact schematizing and formal, if systematic, with a flattening effect.
The use of poetic indirection is a key feature of fu.Frankel (1976), 4 That is the poet may hint at a certain point by subtly and discretely including a comment hinting towards something or by deliberately avoiding saying what the reader would otherwise expect to appear within the highly structured context of the piece. So, on the one hand, the fu style is a lavish and florid rhapsody of almost unrestrained gushing forth upon an explicit topic; but, typically, on the other hand, the authors use the greatest restraint and circumspection to impart a subtle discourse for the discerning and critical reader.
By contrast, ad-hoc stream processors easily reach over 10x performance, mainly attributed to the more efficient memory access and higher levels of parallel processing.Kapasi, Dally, Rixner, Khailany, Owens, Ahn and Mattson, "Programmable Stream Processors", Universities of Stanford, Rice, California (Davis) and Reservoir Labs. Although there are various degrees of flexibility allowed by the model, stream processors usually impose some limitations on the kernel or stream size. For example, consumer hardware often lacks the ability to perform high-precision math, lacks complex indirection chains or presents lower limits on the number of instructions which can be executed.
C# allows the programmer to create user-defined value types, using the `struct` keyword. Unlike classes and like the standard primitives, such value types are passed and assigned by value rather than by reference. They can also be part of an object (either as a field or boxed), or stored in an array without the memory indirection that normally exists for class types. Because value types have no notion of a `null` value and can be used in arrays without initialization, they always come with an implicit default constructor that essentially fills the struct memory space with zeroes.
In various other parts of symbolic programming there are only so many symbols. So to move on to a more significant example, in logic the formula α can refer to any formula, so it could be β, γ, δ, ... or η→π, ς ∨ σ, ... When set-builder notation is employed the statement Δ={α} means the set of all formulae — so although the reference is to α there are two levels of indirection here, the first to the set of all α and then the second to a specific formula for each occurrence of α in the set Δ.
Direct page addressing uses an 8-bit address, which results in faster access than when a 16- or 24-bit address is used. Also, some addressing modes that offer indirection are only possible on direct page. In the 65(C)02, the direct page is always the first 256 bytes of memory, thus "zero page." In native mode, the 65C816 can relocate direct (zero) page anywhere in the first 64KB of memory by writing the starting address into DP. There is a one-cycle access penalty if DP is not set to an even page boundary.
Development of LSM over the next two years was conducted by the LSM community, including substantial contributions from the Immunix Corporation, the NSA, McAfee, IBM, Silicon Graphics, and many independent contributors. LSM was ultimately accepted into the Linux kernel mainstream and was included as a standard part of Linux 2.6 in December 2003. In 2006, some kernel developers observed that SELinux was the only widely used LSM module included in the mainstream Linux kernel source tree. If there is to be only one widely used LSM module, it was reasoned, then the indirection of LSM is unnecessary, and LSM should be removed and replaced with SELinux itself.
Ann Lovett (6 April 1968 – 31 January 1984) was a 15-year-old schoolgirl from Granard, County Longford, Ireland who died giving birth beside a grotto on 31 January 1984.Comment: Emily O'Reilly: The unfinished business of Ann Lovett and what we never managed to learn, Emily O'Reilly, The Times, 30 March 2003, retrieved 3 July 2009 Her baby son died at the same time and the story of her death played a huge part in a seminal national debate on women giving birth outside marriage.The lie of the land, Fintan O'Toole, p.154Folk women and indirection in Morrison, Ní Dhuibhne, Hurston and Lavin, Jaqueline Fulmer, Ashgate, p.
This new version uses "delegation signer (DS) resource records" to provide an additional level of indirection at delegation points between a parent and child zone. In the new approach, when a child's master public key changes, instead of having six messages for every record in the child, there is one simple message: the child sends the new public key to its parent (signed, of course). Parents simply store one master public key for each child; this is much more practical. This means that a little data is pushed to the parent, instead of massive amounts of data being exchanged between the parent and children.
Martin Amis: 30 things I've learned about terror, The Independent, 8 October 2006. In an interview with Mark Lawson in 2006, Amis said there was some distance from the fictionalised versions of himself, his father, Kingsley Amis and his novelist mentor, Saul Bellow, in The Pregnant Widow, at this point untitled. He said he was "trying to keep up a little bit of indirection" with the autobiographical aspects, saying that his character in the novel was named "Louis" (Amis' middle name), that Kingsley Amis was "The King" and that Saul Bellow was "Chick" (which itself was a reference to the Saul Bellow proxy character in Bellow's final novel Ravelstein).Lawson, Mark.
The Crow Terrace Poetry Case had an important and lasting effect on Song dynasty society and culture. The fact that a popular poet and popular government official could be censored and relegated to extreme exile had a chilling effect on freedom of speech (Murck, 49): :::"The 1079 trial and conviction of a prominent figure, one of the realm's most respected scholars, marks a further change in political culture. Civil bureaucrats were losing security along with respect. Su's conviction caused consternation.... Already habituated to elaborate indirection in their commentaries and poetry, anti-reformers were revising or burning poems that might be interpreted as seditious" (Murck, 49).
Warren, the chief clerk in the war office sadly realizes his job is in jeopardy with a new hood of convictions that leads him to follow the dictates of his heart, so he braves the wintry winds of a February storm to visit the fair Iñez at the Mexican embassy. He boldly tells her of his love—in spite of whatever the new powers may fatalize. The fair one with the coquetry of her sex, teases him, but leads him hopefully along by indirection. He starts to go, telling her that he will come for his answer "on the fourth of March", a notoriously busy day in Washington.
A bitmap image file loaded into memory becomes a DIB data structure – an important component of the Windows GDI API. The in-memory DIB data structure is almost the same as the BMP file format, but it does not contain the 14-byte bitmap file header and begins with the DIB header. For DIBs loaded in memory, the color table can also consist of 16-bit entries that constitute indexes to the currently realized paletteMSDN BITMAPINFO Structure (an additional level of indirection), instead of explicit RGB color definitions. In all cases, the pixel array must begin at a memory address that is a multiple of 4 bytes.
The PDP-11 was substantially orthogonal (primarily excepting its floating point instructions). Most integer instructions could operate on either 1-byte or 2-byte values and could access data stored in registers, stored as part of the instruction, stored in memory, or stored in memory and pointed to by addresses in registers. Even the PC and the stack pointer could be affected by the ordinary instructions using all of the ordinary data modes. "Immediate" mode (hardcoded numbers within an instruction, such as ADD #4, R1 (R1 = R1 + 4) was implemented as the mode "register indirect, autoincrement" and specifying the program counter (R7) as the register to use reference for indirection and to autoincrement.
Can Crispin (the artist, the poet, Stevens) hope to be something more than "the intelligence of his soil"? Can the "Socrates of snails" leave his homeland for the sea, and refocus his imagination and refashion himself > On porpoises, instead of apricots, > And on silentious porpoises, whose snouts > Dibbled in waves that were mustachios, > Inscrutable hair in an inscrutable world. The intense word play of "Comedian" is the indirection Stevens needs to address the struggle to grow, which is indeed underway in the poem itself. (Another interpretation would dismiss the word play as Stevens's aestheticism and dandyism/hedonism.) The sea journey causes his old poetic self to be "dissolved", "annulled", leaving only a problematic "starker, barer self", an "introspective voyager".
In 1947, Ayn Rand wrote a pamphlet for the Alliance, entitled Screen Guide for Americans, based on her personal impressions of the American film industry. It read, in excerpt: > The purpose of the Communists in Hollywood is not the production of > political movies openly advocating Communism. Their purpose is to corrupt > our moral premises by corrupting non-political movies -- by introducing > small, casual bits of propaganda into innocent stories -- thus making people > absorb the basic principles of Collectivism by indirection and implication. > The principle of free speech requires that we do not use police force to > forbid the Communists the expression of their ideas -- which means that we > do not pass laws forbidding them to speak.
She reminds us that everything we do on the Internet has an impact on our real life and has consequences far from social networks. Examples of use The experimental composers and artists David Chokroun, Aydem Azmikara, Marc Couroux, Engram Knots, and Vanessa Grey have used "Karen Eliot" to collectively and anonymously write musical compositions during and throughout their lifetimes. According to writer Eldritch Priest, as a composer "Karen Eliot belongs to nobody and is no one…the collective nature and schematic indirection of 'Karen Eliot' circulates her contradictions and inconsistencies in a way that keeps doubt and the status of her reality in play." Many André Éric Létourneau's radio-art works are also signed by Karen Eliot.
With the Appearance Manager, these elements are abstracted into a series of APIs that draw the item as a distinct entity on behalf of the client code, thus relieving the Control Manager of the task. This extra level of indirection allows the system to support the concept of switchable "themes", since client code simply requests the image of an interface element (a button or scroll bar, for example) and draws its appearance. Kaleidoscope, a 3rd party application, was the first to utilize this functionality with via "scheme" files, followed by an updated Appearance Control Panel in Mac OS 8.5, which acted similarly via "theme" files. Schemes and themes are similar in concept, but they are not internally compatible.
Ferguson (joined by all Supreme Court Justices other than John Marshall Harlan), the Supreme Court (in dicta) stated that bans on interracial marriage are constitutional (in spite of them technically being in violation of the freedom of contract, since marriage is technically a contract) and that they are within the police power of the state to make and enforce.) Moreover, only by indirection did the Court address the question of whether, since it was a first offense, the sentence should have been for no more than six months. In any event, the Court had upheld the Alabama laws, and no southern state, for the next eight decades, displayed any inclination to repeal such laws. Certainly, Alabama did not. The Supreme Court's decision in Pace v.
In our daily lives the notion of an "indirect operation" is not unusual. :Example: A treasure hunt. :At location "Tom_&_Becky's_cave_in_pirate_chest" will be where we can find a map directing us to "the treasure": ::(1) We go to location "Tom_&_Becky's_cave..." and dig around until we find a wooden box ::(2) Inside the box is a map to the location of the treasure: "under_Thatcher's_front_porch" ::(3) We go to location "under_Thatcher's_front_porch", jackhammer away the concrete, and discover "the treasure": a sack of rusty door-knobs. Indirection specifies a location identified as the pirate chest in "Tom_&_Becky's_cave..." that acts as a pointer to any other location (including itself): its contents (the treasure map) provides the "address" of the target location "under_Thatcher's_front_porch" where the real action is occurring.
Java has been criticized for not supporting arrays of more than 231−1 (about 2.1 billion) elements. This is a limitation of the language; the Java Language Specification, Section 10.4, states that: > Arrays must be indexed by int values... An attempt to access an array > component with a long index value results in a compile-time error. Supporting large arrays would also require changes to the JVM. This limitation manifests itself in areas such as collections being limited to 2 billion elements and the inability to memory map continuous file segments larger than 2 GB. Java also lacks true multidimensional arrays (contiguously allocated single blocks of memory accessed by a single indirection), which limits performance for scientific and technical computing.
This allows users to determine firsthand the trustworthiness of the people with whom they share their DEAs. "Safe" DEAs that have not been abused can be forwarded to a real email account, while messages sent to "compromised" DEAs can be routed to a special folder, sent to the trash, held for spam filtering, or returned as undeliverable if the DEA is deleted outright. Further, because DEAs serve as a layer of indirection between the sender and recipient, if the DEA user's actual email address changes, for instance because of moving from a university address to a local ISP, then the user need only update the DEA service provider about the change, and all outstanding DEAs will continue to function without updating.
This is a period of seeming calm that precedes any major conflict between rivals where the conspiracy struggles to play catch up and not let its existence be discovered by friend or foe—an important deception hoping to gain both information and time. During the conflict and action, the greater part of this book, the Byzantines are at war with the Sassanid Persian Empire, and the general takes uncharacteristic "great risks" instead of indirection at one point to bring that conflict to a speedy end. This uncharacteristic event in turn partially exposes his conspiracy to his good friend, a fellow general who becomes part of the intrigue and willing co-conspirator thereafter. In the Heart of Darkness primarily revolves around Belisarius learning the strengths and weaknesses of both his Axumite allies and his Malwa enemies.
While a pointer contains the address of the item to which it refers, a handle is an abstraction of a reference which is managed externally; its opacity allows the referent to be relocated in memory by the system without invalidating the handle, which is impossible with pointers. The extra layer of indirection also increases the control that the managing system has over the operations performed on the referent. Typically the handle is an index or a pointer into a global array of tombstones. A handle leak is a type of software bug that occurs when a computer program asks for a handle to a resource but does not free the handle when it is no longer used; this is a form of resource leak, similar to a memory leak for a pointer to memory.
The elimination of multiple indirection made an additional bit available in a memory word containing an indirect address, allowing the maximum memory capacity to be increased from 32K 16-bit words to 64K. The BPC also added an input allowing the "current page" to be relative to the location of the current instruction, rather than a power-of-two aligned page. The BPC was used in a wide range of HP computers, peripherals, and test equipment, until it was discontinued in the late 1980s. Poland manufactured an HP 2114B clone since 1973. The Polish clones were called MKJ-28 (prototype, 1973), SMC-3 (pilot production, 17 machines, 1975-1977) and PRS-4 (production in series over 150 machines, 1978-1987). Czechoslovakia produced its own HP 1000 compatible clones, designated ADT4000 (4300, 4500, 4700, 4900).
Using bcache makes it possible to have SSDs as another level of indirection within the data storage access paths, resulting in improved overall performance by using fast flash- based SSDs as caches for slower mechanical hard disk drives (HDDs) with rotational magnetic media. That way, the gap between SSDs and HDDs can be bridged the costly speed of SSDs gets combined with the cheap storage capacity of traditional HDDs. Caching is implemented by using SSDs for storing data associated with performed random reads and random writes, using near-zero seek times as the most prominent feature of SSDs. Sequential I/O is not cached, to avoid rapid SSD cache invalidation on such operations that are already suitable enough for HDDs; going around the cache for big sequential writes is known as the write-around policy.
Fu is one of the traditional main categories of Classical Chinese poetry, or literature; however, it is traditionally not generally considered not to be a pure form of poetry (having been usually classified as wen rather than shi—however the Chinese terms do not really correspond with the English terms "literature" and "poetry").Davis, xlvi The main characteristics of the fu form are that each individual piece be multisectional, that the sectional divisions are marked in one or more of 3 ways, that the whole piece be monothematic (devoted to 1 explicit topic), and that the description of this topic be exhaustive, both in detail and vocabulary. Other, less apparent features are also typically present, which can be summarized as being part of a process of poetic indirection. Even though subject to extreme minimalism the indirect commentary forms the true crux of this art form.
This register is finite and separate from the registers above; thus the counter machine model is an example of the Harvard architecture # List of labelled, sequential instructions: A finite list of instructions I0 ... Im. The program store (instructions of the finite state machine) is not in the same physical "space" as the registers. Usually, but not always, like computer programs the instructions are listed in sequential order; unless a jump is successful, the default sequence continues in numerical order. Each of the instructions in the list is from a (very) small set, but this set does not include indirection. Historically most models drew their instructions from this set: :: { Increment (r), Decrement (r), Clear (r); Copy (rj,rk), conditional Jump if contents of r=0, conditional Jump if rj=rk, unconditional Jump, HALT } : Some models have either further atomized some of the above into no-parameter instructions, or combined them into a single instruction such as "Decrement" preceded by conditional jump-if-zero "JZ ( r, z )" .
The story has frequently been reprinted, and scholars and devotees of supernatural fiction often cite it as a classic of the genre. E. F. Bleiler wrote that the narrative in the Green Book "is probably the finest single supernatural story of the century, perhaps in the literature", and Michael Dirda has stated: "If I were to list the greatest supernatural short stories of all time, I would start with Arthur Machen’s 'The White People,' about a young girl’s unknowing initiation into an ancient, otherworldly cult." S. T. Joshi has called the diary "a masterpiece of indirection, a Lovecraft plot told by James Joyce", and H. P. Lovecraft himself wrote that "Machen's narrative, a triumph of skilful selectiveness and restraint, accumulates enormous power as it flows on in a stream of innocent childish prattle". As has been intimated above, Lovecraft adopted some of Machen's techniques and terminology for use in his Cthulhu Mythos stories.
Recursion is not allowed in type synonyms in Miranda, OCaml (unless `-rectypes` flag is used or it's a record or variant), and Haskell; so for example the following Haskell types are illegal: type Bad = (Int, Bad) type Evil = Bool -> Evil Instead, it must be wrapped inside an algebraic data type (even if it only has one constructor): data Good = Pair Int Good data Fine = Fun (Bool -> Fine) This is because type synonyms, like typedefs in C, are replaced with their definition at compile time. (Type synonyms are not "real" types; they are just "aliases" for convenience of the programmer.) But if this is attempted with a recursive type, it will loop infinitely because no matter how many times the alias is substituted, it still refers to itself, e.g. "Bad" will grow indefinitely: `Bad` → `(Int, Bad)` → `(Int, (Int, Bad))` → `...` . Another way to see it is that a level of indirection (the algebraic data type) is required to allow the isorecursive type system to figure out when to roll and unroll.
Instead of being able to use the Z80's efficient and fast block move instructions they had to write elaborate routines that first read bytes from video memory into system memory, and then back to another location in video memory, all one byte at a time. To increase the speed to an acceptable level the programmers then often limited the scrolling to 8-pixel steps, which looked primitive in comparison to the 1 or 2 pixel scrolling steps available to the ZX Spectrum or Commodore 64 machines (although the Commodore 64 also used 8-pixel steps it had a fine-scroll register which could compensate for this, the MSX-1 did not). The TMS9918A did have several features to make up for this shortfall, for example a programmable character set which allowed indirection, (to greatly increase scrolling because only the character table had to be moved, instead of the pixel data) and by having 32 hardware sprites. These sprites however were more limited than those in (for example) the Atari-8-bit systems.
On April 20, 2009, Sun and Oracle Corporation announced that they had entered into a definitive agreement under which Oracle would acquire Sun. A June 12 posting on a Sun blog announced a technical NDA-only presentation on ROCK on July 14, 2009 at the Hamburg OpenSolaris Users Group Meeting. On 15 June 2009, the New York Times reported that "two people briefed on Sun’s plans" said the Rock project was canceled. Sun did not comment. Two days later, the EE Times reported that "Sun did not submit a paper on Rock [to Hot Chips 21] leading to speculation the company may have canceled the chip." On 24 June 2009, a presentation on "Speculative Threading & Parallelization" featured "A Novel Pipeline Architecture Implemented in Sun's ROCK Processor" at The 36th International Symposium on Computer Architecture. On 6 August 2009, support for Rock was removed from the OpenSolaris Project. On 13 August 2009, a presentation on "NZTM: Nonblocking Zero-indirection Transactional Memory" written by Fuad Tabba, Mark Moir, James Goodman, Andrew Hay, and Cong Wang, was presented at the 21st ACM Symposium on Parallelism in Algorithms and Architectures in Calgary, Canada. The NZSTM algorithm performance was evaluated on Sun’s forthcoming Rock processor.
