Test Tool Finds Ethernet Wiring Errors | EE Times

Because you need to connect to both ends of a cable to test it, the LANSeeker needs two devices: an active base (which, of course, is portable) and passive remote.

The remote module attaches to the base unit for safekeeping, sliding off to the top. That’s convenient for storage and transport of the tester — it becomes one piece.

I’ve used other cable testers that are two separate pieces, and this design is better because you’re less likely to misplace the remote unit. Pulling the remote from the base was, however, a little harder than I expected, though reattaching it was smooth. Figure shows the remote receiver separated from the base transmitter unit.

Signal interfaces and noise coupling | EE Times


Most systems consist of at least two devices which operate on mains power. Although hum and other problems are often blamed on “improper” earthing, in most cases there is actually nothing wrong with the system earthing — we can’t blame the electrician for our noise problems.

First, a properly installed, fully regulation-compliant mains distribution system will develop small, entirely safe voltage differences between the Protective Earth (PE) connections of all outlets.

Second, even if a system consists entirely of unearthed equipment, small mains-related “leakage” currents will flow in all interconnecting cables.

While these tiny voltages and currents are no problem for lights and household appliances, they can cause serious noise problems if they’re allowed to couple into vulnerable audio signal paths.

Two Steps Forward, One Step Back: The State of Preschool in the U.S. | US News


“Most developed nations now offer universal preschool – even China has committed to pre-K for every 4-year-old by 2020,” Steven Barnett, the institute’s senior co-director, said on a press call Tuesday.

“Meanwhile, the United States has made little progress. This is no way to compete globally now or in the future. Our first step back to leadership is quality preschool.”

The report, “The State of Preschool 2017,” takes into account enrollment, funding, teacher qualifications and other indicators of program quality.

Staff changes upend White House cyber team | TheHill


President Trump’s cybersecurity coordinator, Rob Joyce, revealed this week that he would vacate his post and return to the National Security Agency (NSA), ending a 14-month stint at the White House.

News of his planned departure came less than a week after the resignation of homeland security adviser Tom Bossert. The two men had become the face of the White House’s cybersecurity efforts, providing a line of communication between lawmakers and private industry to the West Wing.

‘I Don’t Get Confused:’ How Nikki Haley’s Feminist Clapback Could Cost Her a Job | GovExec.com


Nikki Haley was just doing her job.

On Sunday (April 15), Haley, who serves as the US ambassador to the United Nations, announced that the Trump administration was planning to impose new sanctions on Russia. Haley said the sanctions would go into effect the following day.

But unbeknownst to Haley, the White House had reportedly decided to change direction—without telling her.

In an effort to fix the situation, and hopefully hide the evidence that no one in the Trump administration knows what’s going on, the White House resorted to a classic move: Blame the mistake on the woman involved.

Given Haley’s refusal to be patronized, the time of her exit may be drawing near.

Five ‘Ethical Leadership’ Values In James Comey’s Book | GovExec.com


Comey writes about what he calls “ethical leadership” and notes that great companies “obsess over leadership talent—they hunt for it, test it, train it, and make it part of every conversation. They treat leadership talent like money.”

What does Comey see as important components of ethical leadership? Here are five main takeaways:

  1. The best leaders don’t overreact to mistakes and use them as teaching moments.
  2. Leaders create an environment where people want to do their best work.
  3. Leaders value humor that shows both confidence and humility.
  4. Leaders listen to dissenting opinions or facts.
  5. Leaders take the long view.

Do You Have “Advantage Blindness”?


No one wants to think they got to the top through an unfair advantage. You want to feel that you’ve earned it — that your hard work and carefully honed skills have paid off.

But the evidence on diversity in the workplace is conclusive: There are lots of people held back by bias. And that means that some of the people at the top have advanced partly through privilege.

The Nordic Glass Ceiling | World Affairs Journal


The emergence of a large public sector has been both positive and negative for women. It played an important historical role in women’s entry into the labor market because many women entered through the expanding public sector. Public-sector services also facilitated the combination of work and the fulfilment of family responsibilities.

The provision of public daycare was particularly important in this regard.

But labor-force participation is only one measure of female professional success. Another measure is female business ownership.

Oklahoma teachers strike: the state’s eduction association says the walkout is over. But many teachers say it’s not. | Vox


The Oklahoma teacher walkout is over — but not for everyone.

“I call on our community members to continue supporting these educators as they walk back into the classroom. We want as much support from them after the walkout as they received during the walkout,” Alicia Priest, president of the Oklahoma Education Association, said during a press conference. The OEA framed the walkout as a victory that ended with millions of dollars more in school funding.

Priest said that most of OEA’s members wanted to resume classes. But despite media reports to the contrary, the association is not a teachers union — it’s a professional association for school administrators, teachers, and retired educators that has no collective bargaining authority, as Priest told Vox.

Google Has Intent to Cut Humans Out of Network | Light Reading

In a presentation at today’s MPLS, NFV and SDN World Congress in Paris, he revealed that Google has about 10,000 switches in operation in a typical large data center and is now handling around 30,000 configuration changes every month. Its search engine currently processes about 3.5 billion searches every day.

“What really stresses out the network is humans,” Vijoy Pandey, Google’s head of engineering for data centers and backbone networks, told his audience at a keynote presentation in Paris. “It is actually humanly impossible to do changes in the size of the network we have. Humans are looking at the design elements but software needs to handle the nitty-gritty.”

Pandey estimates that about 70% of failures happen when a management operation is in progress. The apparent aim is to make improvements through even greater reliance on automation
