A conforming implementation of this Standard shall interpret characters in conformance with the Unicode Standard, Version 3. If the adopted encoding form is not otherwise specified, it presumed to be the UTF encoding form. A conforming implementation of ECMAScript is permitted to provide additional types, values, objects, properties, and functions beyond those described in this specification. In particular, a conforming implementation of ECMAScript is permitted to provide properties not described in this specification, and values for those properties, for objects that are described in this specification.

Free Introduction Learners learn vocabulary by recycling. Keith Folse writes of the importance of providing learners with multiple exposures to new words, so that the words will move from short-term to long-term memory.

The background

This view is also supported by Tom Cobbwhose research demonstrates that when learners encounter words in a variety of contexts they are able to retain and use them flexibly.

The Compleat Lexical Tutor offers a means of doing just that.

With its focus on academic vocabulary, the site will perhaps be of greatest interest to those working with English for Academic Purposes EAP learners. The Compleat Lexical Tutor, site entry web page Dedicated by its webmaster, the aforementioned Tom Cobb of the University of Quebec at Montreal UQAM"to the free dissemination of knowledge on the WWW," this website contains a vast range of resources for both teaching and learning vocabulary and grammar.

As can be seen from the entry page, the site focuses not only on English but also French and Spanish; however, this review will focus on English resources. Since this is quite a large site, with some sections more "finished" than others, it requires some trial and error exploration on the part of the instructor before employment in the classroom.

However, the majority of the programs have been "validated empirically in peer-reviewed papers that are fully and freely available" T. Cobb, personal communication, November 7, Tutorial, Research, and Teachers. Here Cobb explains the rationale for learners to use vocabulary lists: Most of the nearly three dozen or so tools and activity builders are based on either the Academic Word list AWL [ 1 ] or concordancers.

Many instructors of EAP will be familiar with the AWL, a set of high-frequency words that appear in academic texts. These are arranged in a set of 10 sublists, with words on Sublist 1 being the most frequently used, and those on Sublist 10 being the least frequent.

Tutorial The Tutorial section aims to provide self-access learning opportunities for learners. Using interactive tools on the web site, learners can test their vocabulary, explore their vocabulary levels, compare active and passive vocabulary, use new words, read and listen to a novel, and test their grammar with concordances.

Four of the Tutorial activities are described below. Test Your Word Level is adapted for the web from Paul Nation and Batia Laufer's word levels tests, developed for learners with vocabularies of different sizes and types, with the to 10, most frequent English words, including the University Word List, an earlier list of academic words developed by Nation and Xue.

At the word level, the items are multiple-choice and based on either pictures or short sentences.

Beyond this, the items are all gapped-words in sentences, as seen in Figure 2. Test Your Word Level, gapped-word item Learners check their answers and move on to a second test at a higher or lower level, depending on their score.

My pre-entry EAP learners found these tests easy to use but rather alarming, as they discovered their vocabulary was not as strong as previously thought. Their performance on the tests prompted them to investigate the Learn Words link, which takes one to the Linked Lists and guides learners to the words they have answered incorrectly.

Learners type in the word and can hear it pronounced, using the "Speaks for Itself" text-to-speech TTS plug-in available from the site and at www. Then they can locate the definition through a link to WordNet [ 2 ], an online dictionary from Princeton University.Archives and past articles from the Philadelphia Inquirer, Philadelphia Daily News, and attheheels.com For exit codes, I’m using the conventions defined in the UNIX “sysexits.h” header.

It’s the closest thing to a standard I could find. Stick that in a text file, and go get your IDE or Makefile or whatever set up.

Great post, very informative, thanks!

You can now launch D2 instances, the latest generation of Amazon EC2 Dense-storage instances. D2 instances are designed for workloads that require high sequential read and write access to very large data sets, such as Hadoop distributed computing, massively parallel processing data warehousing, and log processing applications.
