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.

Dash

[edit]

Dash is a Python framework built on top of React, a JavaScript library.[30] Dash also works for R, and most recently supports Julia. While still described as a Python framework, Python isn't used for the other languages: "... describing Dash as a Python framework misses a key feature of its design: the Python side (the back end/server) of Dash was built to be lightweight and stateless [allowing] multiple back-end languages to coexist on an equal footing".[31]

It is possible to integrate D3.js charts as Dash components.[32] Dash provides the default CSS (plus HTML and JavaScript), but for custom styling Dash applications, CSS can be added, or Dash Enterprise used.[33]

Dash Enterprise

[edit]

Dash Enterprise is Plotly's paid product for building, testing, deploying, managing and scaling Dash applications organization-wide.[34] The product integrates with enterprise IT systems to enable organizations to build, deploy and scale low-code Dash applications.[35] With open-source Dash, analytic applications can be run from a local machine, but cannot be easily accessed by others in the organization.[36]

Enterprise IT integration

[edit]

Dash Enterprise installs on cloud environments and on-premises. Amazon Web Services, Google Cloud Platform, and Microsoft Azure are supported, as are multiple Linux on-premises servers.[37] Authentication integrations include LDAP, AD, PKI, Okta, SAML, OAuth2, SSO, and email authentication, and Dash application access is managed through a GUI rather than code.[38] Dash Enterprise connects to major big data backends, including Salesforce, PostgreSQL, Databricks via PySpark, Snowflake, Dask, Datashader, and Vaex.[39] In 2020, Plotly partnered with NVIDIA to integrate Dash with RAPIDS,[40] and NVIDIA participated in Plotly's Series C funding round.

Low-code capabilities

[edit]

Dash Enterprise enables low-code development of Dash applications, which is not possible with open-source Dash. Enterprise users can write applications in multiple development environments, including Jupyter Notebook.[41] Dash Enterprise ships with several “development engines” for drag-and-drop application editing, application design, and automated reporting, as well as dozens of artificial intelligence and machine learning application templates.[42][43][44][45]

Deployment and scaling

[edit]

Dash application code is deployed to Dash Enterprise using the git-push command. Dash application deployments are containerized to avoid dependency conflicts, and can be embedded in existing web platforms without iframes.[46][47] Deployed applications can be managed and accessed in a single portal called App Manager, where administrators can control user authentication and view usage analytics.[48][49] Dash Enterprise scales horizontally with Kubernetes.[50] Jobs queuing, GPU acceleration, and CPU parallelization support high performance computing requirements.[51] Plotly also offers professional services for application development and workshop training.

Gunpowder Plot

The Gunpowder Plot of 1605, in earlier centuries often called the Gunpowder Treason Plot or the Jesuit Treason, was an unsuccessful attempted regicide against King James VI of Scotland and I of England by a group of English Catholics, led by Robert Catesby. The plan was to blow up the House of Lords during the State Opening of Parliament on Tuesday 5 November 1605, as the prelude to a popular revolt in the Midlands during which King James's nine-year-old daughter, Princess Elizabeth, was to be installed as the new head of state. Catesby is suspected by historians to have embarked on the scheme after hopes of greater religious tolerance under James had faded, leaving many English Catholics disappointed. His fellow conspirators were John and Christopher Wright, Robert and Thomas Wintour, Thomas Percy, Guy Fawkes, Robert Keyes, Thomas Bates, John Grant, Ambrose Rookwood, Sir Everard Digby and Francis Tresham. Fawkes, who had 10 years of military experience fighting in the Spanish Netherlands in the failed suppression of the Dutch Revolt, was given charge of the explosives. On 26 October 1605, an anonymous letter of warning was sent to William Parker, 4th Baron Monteagle, a Catholic member of Parliament, who immediately showed it to the authorities. During a search of the House of Lords on the evening of 4 November, Fawkes was discovered guarding 36 barrels of gunpowder—enough to reduce the House of Lords to rubble—and arrested. Hearing that the plot had been discovered, most of the conspirators fled from London while trying to enlist support along the way. Several made a last stand against the pursuing Sheriff of Worcestershire and a posse of his men at Holbeche House; in the ensuing gunfight Catesby was one of those shot and killed. At their trial on 27 January 1606, eight of the surviving conspirators, including Fawkes, were convicted and sentenced to be hanged, drawn and quartered. Some details of the assassination attempt were allegedly known by the principal Jesuit of England, Henry Garnet. Although Garnet was convicted of high treason and put to death, doubt has been cast on how much he really knew. As the plot's existence was revealed to him through confession, Garnet was prevented from informing the authorities by the absolute confidentiality of the confessional. Although anti-Catholic legislation was introduced soon after the discovery of the plot, many important and loyal Catholics remained in high office during the rest of King James I's reign. The thwarting of the Gunpowder Plot was commemorated for many years afterwards by special sermons and other public events such as the ringing of church bells, which evolved into the British variant of Bonfire Night of today.

Plotter

A plotter is a machine that produces vector graphics drawings. Plotters draw lines on paper using a pen, or in some applications, use a knife to cut a material like vinyl or leather. In the latter case, they are sometimes known as a cutting plotter. In the past, plotters were used in applications such as computer-aided design, as they were able to produce line drawings much faster and of a higher quality than contemporary conventional printers. Smaller desktop plotters were often used for business graphics. Printers with graphics capabilities took away some of the market by the early 1980s, and the introduction of laser printers in the mid-1980s largely eliminated the use of plotters from most roles. Plotters retained a niche for producing very large drawings for many years, but have now largely been replaced by wide-format conventional printers. Cutting plotters remain in use in a number of industries.
