I’m gonna fight ’em off
A seven nation army couldn’t hold me back
They’re gonna rip it off
Taking their time right behind my back
And I’m talking to myself at night
Because I can’t forget
Back and forth through my mind
Behind a cigarette

And the message coming from my eyes
Says “Leave it alone”

Don’t want to hear about it
Every single one’s got a story to tell
Everyone knows about it
From the Queen of England to the Hounds of Hell
And if I catch it coming back my way
I’m gonna serve it to you
And that ain’t what you want to hear
But that’s what I’ll do

And the feeling coming from my bones
Says “Find a home”

I’m going to Wichita
Far from this opera forevermore
I’m gonna work the straw
Make the sweat drip out of every pore
And I’m bleeding, and I’m bleeding, and I’m bleeding
Right before the Lord
All the words are gonna bleed from me
And I will sing no more

And the stains coming from my blood
Tell me “Go back home”

America’s Cultural Revolution: How the Radical Left Conquered Everything

“For decades, left-wing radicals patiently built a revolution in the shadows. Then suddenly, after the death of George Floyd, their ideas exploded into American life.

Corporations denounced the United States as a “system of white supremacy.” Universities pushed racially segregated programs that forced students to address their racial and sexual “privilege.” And schools injected critical race theory in the classroom, dividing children into “oppressor” and “oppressed.”

In this New York Times bestseller, Christopher F. Rufo exposes the inner history of the left-wing intellectuals and militants who slowly and methodically captured America’s institutions, with the goal of subverting them from within. With profiles of Herbert Marcuse, Angela Davis, Paulo Freire, and Derrick Bell, Rufo shows how activists have profoundly influenced American culture with an insidious mix of Marxism and racialist ideology. They’ve replaced “equality” with “equity,” subverted individual rights in favor of group identity, and convinced millions of Americans that racism is endemic in all of society. Their ultimate goal? To replace the constitution with a race-based redistribution regime, administered by “diversity and inclusion” commissars within the bureaucracy.

America’s Cultural Revolution is the definitive account of the radical Left’s long march through the institutions. Through deep historical research, Rufo shows how the ideas first formulated in the pamphlets of the Weather Underground, Black Panther Party, and Black Liberation Army have been sanitized and adopted as the official ideology of America’s prestige institutions, from the Ivy League universities to the boardrooms of Wal-Mart, Disney, and Bank of America. But his book is not just an exposé. It is a meticulously-researched and passionate refutation of the arguments of CRT—and a roadmap for the counter-revolution to come.”

“To be at home is to have a place in the world which is yours, where you are not a stranger and where you find the outlines of your identity. In the modern world, however, where the sense of home has been eroded by technology and bureaucracy, architecture can create a substitute for this sense, by defining spaces which answer to the dreams and memories of the people who live in them.”

When the wicked problems of peace and economic inequality cannot be solved, political leaders, and the battalions of servile administrative muckety-mucks who report to them, resort to fear-mongering about an imagined problem to be solved centuries hence assuming every other nation agrees on remedies of its anthropogenic origin. We would not draw attention to it were it not that large tranches of the global academic community are in on the grift costing hundreds of billions in square-footage for research and teaching hopelessness to our children and hatred of climate change deniers.

Bricklayers, sometimes known as masons, are skilled craftsmen that must be physically fit, have a high level of mathematical skill and a love for precision and detail.

Bricklaying standards are guidelines and specifications that ensure the quality and safety of bricklaying work. These standards are often established by industry organizations, regulatory bodies, or national building codes. While specific standards may vary by region, some core bricklaying standards include:

Building Codes: Compliance with local building codes is essential. These codes provide regulations for construction practices, including specifications for masonry work. Bricklayers must adhere to the building codes relevant to the specific location of the construction project.

ASTM International Standards: ASTM International (formerly known as the American Society for Testing and Materials) develops and publishes technical standards for various industries, including construction. ASTM standards related to bricklaying cover materials, testing procedures, and construction practices.

Masonry Construction Standards: Organizations like the Masonry Standards Joint Committee (MSJC) in the United States publish standards specifically focused on masonry construction. These standards address topics such as mortar, grout, reinforcement, and structural design considerations.

Quality Control: Standards related to quality control in bricklaying include specifications for mortar mixtures, proper curing of masonry, and guidelines for inspecting finished work. Adherence to these standards helps ensure the durability and longevity of the masonry construction.

Safety Standards: Occupational safety standards, such as those outlined by the Occupational Safety and Health Administration (OSHA) in the United States, are critical for protecting workers on construction sites. These standards cover aspects like fall protection, scaffolding safety, and the proper use of personal protective equipment.

Brick and Block Standards: Standards related to the dimensions, composition, and properties of bricks and concrete blocks are important for achieving structural integrity. These standards specify characteristics such as compressive strength, absorption, and dimensional tolerances.

Construction Tolerances: Tolerances dictate acceptable variations in dimensions and alignments in bricklaying work. These standards help ensure that the finished structure meets design specifications and industry-accepted tolerances.

Testing and Inspection: Standards related to the testing and inspection of masonry work help verify that construction meets specified requirements. This includes procedures for mortar testing, grout testing, and overall quality inspections.

It’s important for bricklayers and construction professionals to be aware of and follow these standards to guarantee the safety, quality, and compliance of their work. Additionally, staying informed about updates to industry standards is crucial as they may evolve over time to reflect advancements in materials, techniques, and safety practices.

Rightsizing Electrical Power Systems

Standards Michigan, spun-off in 2016 from the original University of Michigan Business & Finance Operation, has peppered NFPA 70 technical committees writing the 2016-2026 National Electric Code with proposals to reduce the size of building premise feeder infrastructure; accommodating the improvements made in illumination and rotating machinery energy conservation since the 1980’s (variable frequency drives, LED lighting, controls, etc.)

These proposals are routinely voted down in 12-20 member committees representing manufacturers (primarily) though local inspection authorities are complicit in overbuilding electric services because they “bill by the service panel ampere rating”. In other words, when a municipality can charge a higher inspection fee for a 1200 ampere panel, what incentive is there to support changes to the NEC that takes that inspection fee down to 400 amperes?

The energy conservation that would result from the acceptance of our proposals into the NEC are related to the following: reduced step down transformer sizes, reduced wire and conduit sizes, reduced panelboard sizes, reduced electric room cooling systems — including the HVAC cooling systems and the ceiling plenum sheet metal carrying the waste heat away. Up to 20 percent energy savings is in play here and all the experts around the table know it. So much for the economic footprint of the largest non-residential building construction market in the United States — about $120 billion annually.

The market incumbents are complicit in ignoring energy conservation opportunity. To paraphrase one of Mike Anthony’s colleagues representing electrical equipment manufacturers:

“You’re right Mike, but I am getting paid to vote against you.”

NFPA Electrical Division knows it, too.

Rightsizing Commercial Electrical Power Systems: Review of a New Exception in NEC Section 220.12

Michael A. Anthony – James R. Harvey

University of Michigan, Ann Arbor

Thomas L. Harman

University of Houston, Clear Lake, Texas

For decades, application of National Electrical Code (NEC) rules for sizing services, feeders and branch circuits has resulted in unused capacity in almost all occupancy classes. US Department of Energy data compiled in 1999 indicates average load on building transformers between 10 and 25 percent. More recent data gathered by the educational facilities industry has verified this claim. Recognizing that aggressive energy codes are driving energy consumption lower, and that larger than necessary transformers create larger than necessary flash hazard, the 2014 NEC will provide an exception in Section 220.12 that will permit designers to reduce transformer kVA ratings and all related components of the power delivery system. This is a conservative, incremental step in the direction of reduced load density that is limited to lighting systems. More study of feeder and branch circuit loading is necessary to inform discussion about circuit design methods in future revisions of the NEC.
