A well-intentioned query and the Halloween Problem

Anne Fitzpatrick

 

Abstract:  The author’s description of the Halloween Problem demonstrates the role of cautionary tales in the history of computing. The Halloween Problem emerged in the context of structured query language optimization in relational database research. Normally, a query optimizer works by measuring system calls and paging requests and applying heuristics to the entire access path tree. Query optimization was one of the most challenging tasks facing System R researchers at IBM. These experiments with query optimization form the milieu in which the Halloween Problem emerged.

Annual report and financial statements 31 July 2024 | “Campus” Masterplan

Durham (Dunholm O.E.) as a Northumbrian learning settlement originates with its Cathedral; founded in 995 AD as part of a Benedictine monastery.  Monks maintained libraries and created an intellectual hub for the English speaking peoples.  Fast forward a millennium and we find “DU Coffee Society” which describes itself as a welcoming space for students to learn about coffee making, latte art and each other.

Energy Standard for *Sites* and Buildings

Addendum av to ANSI/ASHRAE/IES Standard 90.1-2022, Energy Standard for Sites and Buildings Except Low-Rise Residential Buildings. This addendum creates more exacting provisions for envelope alterations. The new format is intended to better communicate the requirements, triggers, and allowances associated with performing an envelope alteration to promote energy efficiency within the impacted area(s).  Consultation closes October 6.

ANSI Standards Action Weekly Edition | Given ASHRAE’s revision redlines are frequently uploaded here

The American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) is an ANSI-accredited continuous-maintenance standards developer (a major contributor to what we call a regulatory product development “stream”).   Continuous maintenance means that changes to its consensus products can change in as little as 30 days so it is wise to keep pace.

Among the leading titles in its catalog is ASHRAE 90.1 Energy Standard for Sites and Buildings Except Low-Rise Residential Buildings.  Standard 90.1 has been a benchmark for commercial building energy codes in the United States and a key basis for codes and standards around the world for more than 35 years.  Free access to ASHRAE 90.1 version is available at the link below:

READ ONLY Version of 2022 ASHRAE 90.1

Redlines are released at a fairly brisk pace — with 30 to 45 day consultation periods.  A related title — ASHRAE 189.1 Standard for the Design of High Performance Green Buildings — first published in 2009 and far more prescriptive in its scope heavily  references parent title 90.1 so we usually them as a pair because 189.1 makes a market for green building conformance enterprises. Note the “extreme prescriptiveness” (our term of art) in 189.1 which has the practical effect of legislating engineering judgement, in our view.

Education estate managers, energy conservation workgroups, sustainability officers, electric shop foreman, electricians and front-line maintenance professionals who change lighting fixtures, maintain environmental air systems are encouraged to participate directly in the ASHRAE consensus standard development process.

We also maintain ASHRAE best practice titles as standing items on our Mechanical, Water, Energy and Illumination colloquia.  See our CALENDAR for the next online meeting; open to everyone.

“In the sweat of thy face shalt thou eat bread, till thou return unto the ground;
for out of it wast thou taken: for dust thou art, and unto dust shalt thou return.

Genesis 3:19 

“Marat Assassinated” | Jacques-Louis David 1793

There are several ANSI accredited standards that apply to mortuary science, particularly in the areas of forensic science and medicolegal death investigation. These standards are developed to ensure the highest levels of professionalism, quality, and consistency in the field. Here are some key standards:

  1. ANSI/ASB Best Practice Recommendations: The American National Standards Institute in collaboration with the American Academy of Forensic Sciences has developed various standards, including those related to the handling and processing of human remains. For example, the ANSI/ASB Best Practice Recommendation 094-2021 outlines procedures for postmortem friction ridge print recovery, emphasizing systematic approaches and legal compliance during the process​
    ANSI/ASB Standard 125-2021: This standard focuses on the general requirements for medicolegal death investigation systems. It covers infrastructure, personnel training, and competency requirements to ensure high-quality death investigations. It also references other professional guidelines and accreditation checklists from organizations such as the National Association of Medical Examiners and the International Association of Coroners and Medical Examiners

These standards are integral to maintaining rigorous protocols and ethical practices within mortuary science and related fields. They help ensure that procedures are consistent, legally compliant, and respectful of the deceased, ultimately contributing to the reliability and credibility of forensic investigations. For more detailed information, you can refer to the ANSI and ASB standards documentation available through their respective organizations.

Anatomical donation programs are supported by relatively stable best practice literature that are highly cross-referencing.  The organ donation industry grows at a surprising clip and, as such, has its share of sketchy actors.

Our discussion today — at 15:00 UTC– is limited to the safety and sustainability of the support facilities for human cadavers only; with attention to the most recent construction projects.
