A very new PhD student research group working on C semantics has just appeared on the horizon. You can tell they are very new to C semantics by the sloppy wording in their survey of C users (what is a ‘normal’ compiler and how does it differ from the ‘current mainstream’ compiler referred to in some questions? I’m surprised the outcome appeared clear to the authors, given the…

Rent now * Final gross prices may vary according to local VAT. Abstract The textual Object Constraint Language (OCL) is primarily intended to specify restrictions over UML class diagrams, in particular class invariants, operation pre-, and postconditions. Based on several improvements in the definition of the language concepts in last years, a proposal for a new version of…

I’d love to be able to produce graphs where I chose the color coding pattern for particular tags. I could set all non-semantic tags to be bright red, to easily spot the condition of a site in that respect. I could focus my attentions on inline versus block elements, or I could differentiate between different levels of headings. More recently, I received comments on that post…

Move semantics does not return a fake copy. Instead, in a copy operation, it gives the copyee permission to trash the original copy. A motivating example may be instructive: std::vector bigData; // fill bigData std::vector listOfData; listOfData.push_back(std::move(bigData)); // after this point, the contents of bigData are unspecified (however accessing it is _not_ undefined…

I might be misunderstanding the question or twisting it off topic, but I think this is relevant: At least three organizations are focusing on semantic work that is used by newspaper, magazine and TV websites in various ways: DocumentCloud, with ties to the New York Times and Pro Publica, makes it easy for other news organizations to upload, annotate and share existing documents…

Followup on this earlier question, ) There is a reasonable fear that attributes will be used to create language dialects. The recommendation is to use attributes to only control things that do not affect the meaning of a program but might help detect errors (e.g. [[noreturn]]) or help optimizers (e.g. [[carries_dependency]]). Yes, this argument was used. I’m (even) more conservative…

The outline shows I’ve set up each block of content inside the header, footer, and sidebar at an equal level in the hierarchy to the article. I don’t know, but it’s a good question to ask and think about. If sidebar content should be at a lower level in the hierarchy, it suggests I should find a different way to markup sidebar content. For example changing div class=”sidebar”…

The definitive categorization of memory is an example of semantics (an irony I enjoy in answering this question). Firstly, you have asked four questions in one. Definition of adjective relating to meaning in language or logic. Semantic is the imposed meaning that human beings give things. Remembering a list of words, would be semantic memory, as the person is required to recollect…

Semantic Feature Comparison Model is used to derive predictions about categorization times in a situation where a subject must rapidly decide whether a test item is a member of a particular target category . In this semantic model, there is an assumption that certain occurrences are categorized using its features or attributes of the two subjects that represent the part and…

In order to improve the retrieval accuracy of content-based image retrieval systems, research focus has been shifted from designing sophisticated low-level feature extraction algorithms to reducing the ‘semantic gap’ between the visual features and the richness of human semantics. This paper attempts to provide a comprehensive survey of the recent technical achievements in…

The title of today’s post is actually one of my blog’s categories, shown at the lower right-hand side of the screen. Someone was wondering about the difference, so I thought I’d explain. What follows here is not dictionary-type definitions, but rather my own “feel” for each of these terms after teaching English for many years. I hope it’s not too boring :) GRAMMAR refers to…

The simple answer is you should write code for rvalue references like you would regular references code, and you should treat them the same mentally 99% of the time. This includes all the old rules about returning references (i.e. never return a reference to a local variable). Unless you are writing a template container class that needs to take advantage of std::forward and…

Semantics is defined as the study of meanings expressed by the elements of a language or a combination of the elements. A concept expressed in an ASL sign often cannot be conveyed by a single all-purpose English word. Likewise, English words and phrases may have variations in meaning, which require translations using different ASL signs. This workshop on DVD helps the participant…

“Web services” is the name for an important set of technologies for developing large-scale distributed systems, under the umbrella of Service-oriented architectures (SOA). Semantic Web services are building on top of Web services technology by describing various aspects of services using explicit, machine-understandable semantics that enable a certain degree of automation for…

As the name indicates, use unique_ptr when there must exist exactly one owner to a resource. The copy constructor of unique_ptr is disabled, which means it is impossible for two instances of it to exist. However, it is movable Which is fine, since that allows transfer of ownership. Also as the name indicates, shared_ptr represents shared ownership of a resource. However, there…

Even though some children are verbal and can communicate with speech, they may have difficulties with the use of language and the “rules” of conversation in social situations. Although this is true of children on the autism spectrum, particularly those with Asperger’s Syndrome, some children do not have that full diagnostic picture and only exhibit the language difficulties…
