Xah at Blogger: list comprehension, python, semantics & syntax, and the hacker idiocies

He wants us to use list comprehension exclusively. see Lambda in Python 3000. if you don't know what list comprehension is, see Python Tutorial: List Comprehension list comprehension is no good. see Computer Language Design: What's List Comprehension and Why is It Harmful? Still, the python hacker idts defend it by “its faster”. In which, python compiler idcy comes forward to defend python language idcy, like a snake eating its tail. however, there's one important semantic advantage of list comprehension. By the way, idts will start to talk about list comprehension as analogous to math's set comprehension and stuff. Math's set comprehension notation is a idiocy, first of all. see:

Design patterns are reusable solutions to commonly occurring problems in software design. They are both exciting and a fascinating topic to explore in any programming language. One reason for this is that they help us build upon the combined experience of many developers that came before us and ensure we structure our code in an optimized way, meeting the needs of problems we're attempting to solve. Design patterns also provide us a common vocabulary to describe solutions. This can be significantly simpler than describing syntax and semantics when we're attempting to convey a way of structuring a solution in code form to others.

In this book we will explore applying both classical and modern design patterns to the JavaScript programming language. Target Audience This book is targeted at professional developers wishing to improve their knowledge of design patterns and how they can be applied to the JavaScript programming language.

Syntax of CTL[edit] The language of well formed formulas for CTL is generated by the following grammar: where ranges over a set of atomic formulas.

Not all of these connectives are needed – for example, comprises a complete set of connectives, and the others can be defined using them. means 'along All paths' (Inevitably) means 'along at least (there Exists) one path' (possibly) Color Scheme Designer 3. Circuit simplification examples : Boolean Algebra. Let's begin with a semiconductor gate circuit in need of simplification. The "A," "B," and "C" input signals are assumed to be provided from switches, sensors, or perhaps other gate circuits. Where these signals originate is of no concern in the task of gate reduction.

Our first step in simplification must be to write a Boolean expression for this circuit. This task is easily performed step by step if we start by writing sub-expressions at the output of each gate, corresponding to the respective input signals for each gate. Remember that OR gates are equivalent to Boolean addition, while AND gates are equivalent to Boolean multiplication.

Problem Suppose we have a relatively standard library function for attaching event handlers to elements that works with both the DOM2 and Internet Explorer event models. var LIB = {}; LIB.on = function(element, type, callback) { // ... }; Ometa/ometa-js-old/prolog-base.js. ACE - The High Performance Code Editor for the Web. Web Features: Create a Mashup using our Web Integrator. Produce APIs on your own Convertigo's tools, built on our years of experience, provide you the confidence to produce an API around an existing site--be it public or your own--that will be useful for a long time to come.

Web Features: Create a Mashup using our Web Integrator

This tool makes the site modernization possible less expensively and on a much faster timeline than a complete rewrite. You can also use Web Integrator selectively so that even if you choose to rewrite heavily used sections, you can still use CWI for everything else, which majorly optimizes your resources. Create widgets with Convertigo's Web Clipper Save time and money with our Web Integrator. Component-based software engineering. A simple example of two components expressed in UML 2.0.

Component-based software engineering

The checkout component, responsible for facilitating the customer's order, requires the card processing component to charge the customer's credit/debit card (functionality that the latter provides). Component-based software engineering (CBSE) (also known as component-based development (CBD)) is a branch of software engineering that emphasizes the separation of concerns in respect of the wide-ranging functionality available throughout a given software system.

It is a reuse-based approach to defining, implementing and composing loosely coupled independent components into systems. This practice aims to bring about an equally wide-ranging degree of benefits in both the short-term and the long-term for the software itself and for organizations that sponsor such software. Mobl.

Portlet. Portlets are pluggable user interface software components that are managed and displayed in a web portal.


Portlets produce fragments of markup (HTML, XHTML, WML) code that are aggregated into a portal. Typically, following the desktop metaphor, a portal page is displayed as a collection of non-overlapping portlet windows, where each portlet window displays a portlet. Web portal. A portal may use a search engine API to permit users to search intranet content as opposed to extranet content by restricting which domains may be searched.

Web portal

Apart from this common search engines feature, web portals may offer other services such as e-mail, news, stock quotes, information from databases and even entertainment content. Portals provide a way for enterprises and organizations to provide a consistent look and feel with access control and procedures for multiple applications and databases, which otherwise would have been different web entities at various URLs. The features available may be restricted by whether access is by an authorized and authenticated user (employee,member) or an anonymous site visitor. Examples of early public web portals were AOL, Excite, Netvibes, iGoogle, MSN, Naver, Indiatimes, Rediff, Sify and Yahoo!. See for example, the "My Yahoo! " Mashup (web application hybrid) A mashup, in web development, is a web page, or web application, that uses content from more than one source to create a single new service displayed in a single graphical interface.

Mashup (web application hybrid)

For example, you could combine the addresses and photographs of your library branches with a Google map to create a map mashup.[1] The term implies easy, fast integration, frequently using open application programming interfaces (open API) and data sources to produce enriched results that were not necessarily the original reason for producing the raw source data.

The term mashup originally comes from British - West Indies slang meaning to be intoxicated, or as a description for something or someone not functioning as intended. In recent American English parlance it can refer to music, where people seamlessly combine audio from one song with the vocal track from another—thereby mashing them together to create something new. The term isn't formally defined by any standard-setting body.[2] Home — Scriptaculous Documentation. Script.aculo.us is a set of JavaScript libraries to enhance the user interface of web sites.

In my talk from London Ajax, we'll explore the current state of MVC in the JavaScript community, how Smalltalk-80's MVC differed and whether modern frameworks abuse (or evolve) the MVC pattern. We'll also look at a framework that tries to stick more closely to Smalltalk MVC and close up with a panel discussion. For readers/redditors/hacker news readers, I'd love to hear your takes on these topics too so feel free to comment below or contribute to the discussion.
