MY'STORY

The MOVE Fire

This is a personal recollection on the Move fire on May 13, 1985 Philadelphia police fired thousands of rounds at the MOVE house, city officials approved dropping an explosive device on the roof, the resulting fire was allowed to burn, 11 people—including five children—died, and 61 homes were destroyed. Philadelphia City Council later called it a “brutal attack carried out by the City of Philadelphia on its own citizens” and acknowledged that no individual faced criminal consequences for the bombing. One timeline correction worth preserving for the BHP record: the major previous MOVE-police confrontation was August 8, 1978, about seven years before the bombing, not a year or two earlier. Officer James Ramp was killed, other police and firefighters were wounded, nine MOVE members were later convicted, and television cameras recorded police beating Delbert Africa during his arrest. The 1985 MOVE Commission later specifically criticized city planners for failing to adequately use lessons from that 1978 confrontation. And that actually strengthens the point you’re making: 1985 did not happen without precedent or institutional memory. There had already been a deadly confrontation with MOVE, years of conflict, negotiations and police involvement before Osage Avenue.

Software visualization

Not to be confused with Visualization (graphics).

Software visualization[1][2] or software visualisation refers to the visualization of information of and related to software systems—either the architecture of its source code or metrics of their runtime behavior—and their development process by means of static, interactive or animated 2-D or 3-D[3] visual representations of their structure,[4] execution,[5] behavior,[6] and evolution.

Software system information

[edit]

Software visualization uses a variety of information available about software systems. Key information categories include:

Objectives

[edit]

The objectives of software visualization are to support the understanding of software systems (i.e., its structure) and algorithms (e.g., by animating the behavior of sorting algorithms) as well as the analysis and exploration of software systems and their anomalies (e.g., by showing classes with high coupling) and their development and evolution. One of the strengths of software visualization is to combine and relate information of software systems that are not inherently linked, for example by projecting code changes onto software execution traces.[7]

Software visualization can be used as tool and technique to explore and analyze software system information, e.g., to discover anomalies similar to the process of visual data mining.[8] For example, software visualization is used to monitoring activities such as for code quality or team activity.[9] Visualization is not inherently a method for software quality assurance.[citation needed] Software visualization participates to Software Intelligence in allowing to discover and take advantage of mastering inner components of software systems.

Types

[edit]

Tools for software visualization might be used to visualize source code and quality defects during software development and maintenance activities. There are different approaches to map source code to a visual representation such as by software maps[10] Their objective includes, for example, the automatic discovery and visualization of quality defects in object-oriented software systems and services. Commonly, they visualize the direct relationship of a class and its methods with other classes in the software system and mark potential quality defects. A further benefit is the support for visual navigation through the software system.

More or less specialized graph drawing software is used for software visualization. A small-scale 2003 survey of researchers active in the reverse engineering and software maintenance fields found that a wide variety of visualization tools were used, including general purpose graph drawing packages like GraphViz and GraphEd, UML tools like Rational Rose and Borland Together, and more specialized tools like Visualization of Compiler Graphs (VCG) and Rigi.[11]: 99–100  The range of UML tools that can act as a visualizer by reverse engineering source is by no means short; a 2007 book noted that besides the two aforementioned tools, ESS-Model, BlueJ, and Fujaba also have this capability, and that Fujaba can also identify design patterns.[12]

List of alignment visualization software

This page is a subsection of the list of sequence alignment software. Multiple alignment visualization tools typically serve four purposes: Aid general understanding of large-scale DNA or protein alignments Visualize alignments for figures and publication Manually edit and curate automatically generated alignments Analysis in depth The rest of this article is focused on only multiple global alignments of homologous proteins. The first two are a natural consequence of most representations of alignments and their annotation being human-unreadable and best portrayed in the familiar sequence row and alignment column format, of which examples are widespread in the literature. The third is necessary because algorithms for both multiple sequence alignment and structural alignment use heuristics which do not always perform perfectly. The fourth is a great example of how interactive graphical tools enable a worker involved in sequence analysis to conveniently execute a variety if different computational tools to explore an alignment's phylogenetic implications; or, to predict the structure and functional properties of a specific sequence, e.g., comparative modelling.

Music visualization

Music visualization or music visualisation is animated computer-generated imagery based on a piece of music. The imagery is usually generated and rendered in real time, synchronizing with the music as it is played. The feature is found in electronic music visualizers and media player software. Visualization techniques range from simple ones (e.g., a simulation of an oscilloscope display) to elaborate ones, which often include a number of composited effects. The changes in the music's loudness and frequency spectrum are among the properties used as input to the visualization. Effective music visualization aims to attain a high degree of visual correlation between a musical track's spectral characteristics such as frequency and amplitude and the objects or components of the visual image being rendered and displayed. In modern usage, a basic music video that does not feature synthetic imagery, but nevertheless does not present a defined narrative (although it may comprise footage of real people or events), may also be termed a "visualizer".

Greenwood / Black Wall Street

Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
