Ender 3 Filament Settings

Settings for Ender 3 for different filaments

  PLA (Polylactic acid) - Most common 3D printing material. But what does it take to print it on the Ender 3?  Quite simply, nothing much. PLA is a versatile material, hard brittle.
Printing temperature 180-230 °C
Build plate temperature A modest 20-60 °C helps a lot. Any higher and the PLA at the bottom might deform.
Bed adhesion The stock build surface on the Ender 3 provides excellent bed adhesion for PLA. But for a smoother bottom surface, glass is a better option. When using glass, hairspray or glue stick work the best. They give your prints a good hold on the bed.
Print speed A general recommended speed of 60 mm/s works great, balancing quality with printing time.
Retraction As the Ender 3 has a Bowden style setup, retraction settings are much higher. We only need to consider two factors here.
  Retraction distance: 5 mm
  Retraction speed: 45 mm/sec
Part-cooling fan This should be on.

How to restore missing command history on Mac iTerm

I noticed on my Mac that sometimes my command history gets lost. In researching I came across this article Bash History missing from Terminal

I build this script which I place in my home directory, but it could be any place as long as it is run from the user who lost their command history.  The features are that it will find any commands that are missing from the .bash_history and add them while preserving the order of the existing command history.

$ more
# Restore missing command history for user
MYUSER=`id -un`
cat /Users/$MYUSER/.bash_sessions/*.history | sort | uniq >> /Users/$MYUSER/.bash_history2

# copy missing command history to bash_history
awk '{if (f==1) { r[$0] } else if (! ($0 in r)) { print $0 } } ' f=1 /Users/$MYUSER/.bash_history f=2 /Users/$MYUSER/.bash_history2 >> .bash_history
rm /Users/$MYUSER/.bash_history2

Executive Summary

Leadership doesn’t always come with titles and positions.

Leadership is all about taking responsibility.

A leader is someone who not only sees hidden potential in people and things but also takes the responsibility of developing that potential.

They create an environment where everyone feels a sense of belonging to their work.

Silos, Politics and Turf Wars

A Leadership Fable About Destroying the Barriers That Turn Colleagues Into Competitors

By Patrick Lencioni

SUMMARY The concept of “silos” has become synonymous with the barriers that separate work teams, departments and divisions — causing people who are supposed to be on the same team to work against one another. These maddening factions breed the office politics and in-fighting which ultimately kill productivity, squash profits and push the best people out the door. Silos cause stress, exasperation and disappointment by forcing employees to fight unwinnable battles with people who should be teammates. In this summary, New York Times’ bestselling author and acclaimed management expert Patrick Lencioni presents a dynamic leadership fable that reveals how organizations can overcome the “silos” that divide work units and paralyze performance. This summary also offers solutions to a key leadership issue — the impact of turf wars and political infighting on organizational effectiveness. Written in the form of a realistic but fictional story, this summary tackles a tough business issue in both an entertaining and instructive way.

Data Center Greyhound

First America – Owns Grey Hound, several trains, and 50,000 school buses

Talked to Michael Gross CTO 513-967-7406 Cincinnati OH.  They lost their secondary data center in Plano Texas last week to fire.  They will be completely down for 3+ weeks, and then in 45 days will need to migrate to a replacement permanent location.  The data center had one critical production system that had its own private UPS and when the fire alarm started and shutdown the main UPS and power to the room that UPS was still powering the critical system, when the water dumped it fried the system.  This was a large data center with no isolation so all the systems got wet.  Most of the tapes on site could be dried out.  This many of the servers are currently drying and in a week they can test power them to see how many can be saved.

Contamination at CDC lab was likely cause of critical early delays in rolling out coronavirus testing

(CNN)Contamination in manufacturing the Centers for Disease Control and Prevention test for the coronavirus caused weeks of delays that slowed the US response to the pandemic, multiple health officials have told CNN, a problem that stemmed in part from the CDC not adhering to its own protocols, according to a US Food and Drug Administration spokesperson.

"CDC made its test in one of its laboratories, rather than in its manufacturing facilities," the FDA spokesperson told CNN on Saturday. "CDC did not manufacture its test consistent with its own protocol."

The government has never fully explained what stalled the rollout of a crucial test needed to begin measuring the extent of the spread of Covid-19. It would take until the end of February to correct and the US continues to lack extensive testing capability even as some states prepare ease up on restriction and reopen to a degree.

Zero Trust Networks

A summary from The First Step Towards Zero Trust

By Wiggs Civitillo

Zero trust embodies the idea that instead of relying on trust-based perimeter defenses (e.g., firewalls, DMZs), companies need interlinked security measures spanning their ecosystems that can enforce policies based on user context, data access controls, and device postures. Simply put, zero trust is a framework that facilitates a, “Never trust, always verify,” approach to cybersecurity.

When deployed effectively, the zero trust framework can provide companies the ability to monitor and defend against the lateral movement of malicious actors and code that has rendered perimeter defenses inadequate. Sophisticated cybercriminal attacks like denial-of-service, command-and-control, cryptojacking, phishing, ransomware, and even social engineering—to name a few— could be more readily addressed and prevented, saving companies an average of $2.3 million per incident.
