documentation for the BASIS Library

MLton is run from the command line with a collection of options fol lowed by a file name and a list of files with which to compile,
assemble, and link with. The simplest case is to run mlton foo.sml, where foo.sml contains a valid SML program, in which case MLton compiles the program to produce an executable foo. Since MLton does not support separate compilation, the program must be the entire program you wish to compile. However, the program may refer to signatures and structures defined in the Basis Library.

The ability to define new identifiers is central to every high-level programming language. Identifiers are the way that programmers refer to constructs they create; different uses of identifiers correspond to the different abstraction mechanisms provided by the programming language. Let’s take a closer look at the way that identifiers are used in ML.

The applet API lets you take advantage of the close relationship that applets have with Web browsers. The API is provided by the javax.swing.JApplet class and the java.applet.AppletContext interface.
-
Like applications, applets are created from classes. However, applets do not have a main method as an entry point, but instead, have several methods to control specific aspects of applet execution.

This is the example of opening a url in same window from an applet. This program shows that how a url is opened in same document or browser window.

The decidedly more abrasive, awkwardly-named NY shoegazers A Place to Bury Strangers, who will do a few shows at American colleges before spending April in the UK and Europe.

Sneaking out under the radar, it was nonetheless an inspiring mixture of old and new, taking the psychedelic template and stretching it until it breaks. After touring with MGMT the group became a must see attraction, using their own, hand-built guitar pedals to produce some extreme noises.

Demonstration applets and source code are included below. To run the applets, click on a link below with your web browser, or use AppletViewer to open the file named example1.html in the the applet’s subdirectory.
-
When you put an applet on your page you will need to save the applet on your server as well as the HTML page the applet is embedded in. When the page is loaded by a visitor the applet will be loaded and inserted on the page where you embedded it.

This tutorial will take you step by step through the process of building applets. I have chosen for a Learn-By-Example method, the fastest way to learn.
You will not learn the “Why” but the “How”. Throughout the java tutorial all new lines of code are explained, the ones you have already seen aren’t commented anymore.
-
This site is meant to be a quick-and-dirty introduction to writing Java applets. A set of example applets are given to be used as exercises. Feel free to download the source code herein, try it out on your own machine, and modify it.

The JavaSound API adds audio capabilities to the Java platform. It’s been part of J2SE since version 1.3 and it supports the WAV, AU, and AIFF audio formats, and provides MIDI support. It doesn’t support some other audio formats, such as MP3, but it provides a flexible plugin architecture allowing any third-party vendor to add custom audio format support through the JavaSound Service Provider Interfaces (SPIs). This article deals with this plugin architecture and API, how to write and use a custom SPI implementation, how metadata such as title, artist, and copyright are exposed, and how multiple SPI implementations could be integrated in an application such as player or a game.

Here is the official web page of the JLayer project:

Director Dylan Mulick envisions A Place to Bury Strangers’ lo-fi sonic assault with an over-saturated, grainy fuzz-bomb of a video, interspersing some Smokey and the Bandit-era roadster film with live footage of the band. It’s a psychedelic roadtrip whose chopped cuts and strobe-light shutter effects manage to match the song’s intensity.

There are some really epic bands, but they are sprinkled over 3 days instead of the traditional 2, which really leaves me hard pressed to find the “winner” show date. Friday boasts such bands as Leonard Cohen, Beirut, Crystal Castles, and A Place to Bury Strangers.

I’m teaching a section of Object-oriented Analysis & Design. We’re using java, and so we’re using Javadoc. Here are some links to which I refer my students.
-
This document describes the style guide, tag and image conventions we use in documentation comments for Java programs written at Java Software, Sun Microsystems. It does not rehash related material covered elsewhere: For reference material on Javadoc tags, see the Javadoc reference pages.
For the required semantic content of documentation comments, see Requirements for Writing Java API Specifications.
- Javadoc (tags: tutorial javadoc)
- Java theory and practice: I have to document THAT? “Integrated documentation a la Javadoc is both a benefit and a burden” (tags: javadoc)

In my aforementioned class on Object-oriented Analysis and Design we, of course, study design patterns. Here are a few links concerning the observer pattern.
-
In object-oriented programming, objects contain both data and behavior that, together, represent a specific aspect of the business domain. One advantage of using objects to build applications is that all manipulation of the data can be encapsulated inside the object.
-
Here’s the problem: You’re designing a program that will render data describing a three-dimensional scene in two dimensions. The program must be modular and must permit multiple, simultaneous views of the same scene. Each view must be able to display the scene from a different vantage point, under different lighting conditions. More importantly, if any portion of the underlying scene changes, the views must update themselves.
-
The so-called Observer design pattern is introduced in [1]. The following article describes this pattern, tries to explain why the pattern is helpful and takes a closer look at several consequences of using the pattern. Code examples are given in a java-like syntax.
-
Design patterns document recurring solutions to recurring problems in object-oriented software design. They capture design expertise in reusable form. A design pattern has a name, a description of the problem it addresses, and a general solution that designers must tailor to their particular variant of the problem

Abstract: This tutorial provides a quick introduction to the Unified Modeling Language
-
The Unified Modeling Language™ - UML - is OMG’s most-used specification, and the way the world models not only application structure, behavior, and architecture, but also business process and data structure.

We recently got sent a full-length by the manager of A PLACE TO BURY STRANGERS, not only are they a fantastic, ear-bleeding band, their manager happens to be one of the good guys in this business.
-
First post, i guess goes to a band that i am genuinely excited about. a place to bury strangers. Perhaps I am a little behind the times, but such is the way of anything genuinely Irish.

A Place To Bury Strangers, hailed as the loudest band in New York City, bring their sonic atmosphere of ecstasy to Clark. The Baltic Sea (from Portland, ME) open the show, offering up their carefully crafted cathartic post-rock experience. This is truly a show you should not miss. Saturday February 7th. Doors open 8:30pm
-
And check this out: We’ve got a pair of tickets to go see A Place to Bury Strangers at the Belly Up. If you said, meh, you must’ve been on either bed rest or house arrest last year when these cats played the Larimer. Devastating. Also, did we mention that the tix give you VIP seating with bottle service.
-
When I ordered this, I was stoked! APTBS have become one of my favorite bands and having something this cool to preorder was right up my alley.

But here’s the truth: The overuse of adverbs is taboo in these days of “I’m in a hurry and don’t waste my time.” If you use too many unnecessary words, your words won’t get read.

If Tom Waits’ burbony voice doesn’t do it for you, there’s also the new kids, A Place To Bury Strangers, who’s song “I Know I’ll See You” is astonishingly similar to early stuff from The Cure. FreeIndie writes, “These guys create psychedelic surf music by playing clean guitars over loud feedback and drums. Warning to the close minded: this is unlike anything you’ve ever heard.” He’s right, it’s serious stuff and falls a bit into the experimental but, it’s definately worth a listen.

If you download many programs and files off the Internet, you’ve probably encountered ZIP files before. This compression system is a very handy invention, especially for Web users, because it lets you reduce the overall number of bits and bytes in a file so it can be transmitted faster over slower Internet connections, or take up less space on a disk. Once you download the file, your computer uses a program such as WinZip or Stuffit to expand the file back to its original size. If everything works correctly, the expanded file is identical to the original file before it was compressed.
