In postgresql each connections are spawning as a process under the root process tree of Linux systems. This project allows you to pickup your long running or huge resource consuming queries (you can pick the queries with any of the queries from pg_activity table) then easily migrate PID's given cgroup via REST API. I hope it would be a usefull projects by sysadmins, dba and SRE members

We start with the Constitution:

"AMENDMENT XIV

Section 1.

All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside. No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws."

The text has both words "Citizen" and "Person".

So, we have two cases:

(1) The words "Citizen" and "Person" mean the same:

Then "citizens" get "due process of law" and "equal protection of the laws", and for a suspected non-citizen we have:

"Are you legally in the US? Papers please? No papers? Okay, you're OUT'A here TODAY."

(2) The words "Citizen" and "Person" do not mean the same:

Then

"No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States ..."

applies only to citizens; states are free to "abridge" with non-citizens; and for a suspected non-citizen again we have:

"Are you legally in the US? Papers please? No papers? Okay, you're OUT'A here TODAY."

So, in both cases (1) and (2) we have that STATES are free to "abridge" with non-citizens, e.g., have ICE deport them immediately, no lawyers or judges involved.

Hi,

We’re working on a portable optical laser ground station for communications, and I’m looking for feedback on the setup for our upcoming field test.

We are operating in the 300–400 terahertz (THz) range, and our first prototype aims to achieve 100 Gbps. The system leverages filamentation effects of high-powered lasers to propagate the signal through free space by creating a clear channel through atmospheric turbulence.

While we’ve successfully tested this in a lab environment, we’re now preparing for a field test using a laser with a peak energy close to 1 MJ and pulse durations of ~90 femtoseconds.

We’ve been bootstrapped so far and want to ensure we’re meeting all laser safety requirements, especially given we’re firing through open space. We’re currently fundraising to purchase components for the field laser, which gets expensive very quickly—so we want to be absolutely sure we have the right specs and safety protocols in place.

For safety, we are using a camera and tracking software to monitor free space in real time and ensure there are no aircraft or satellites in the beam path during testing. We are several km's out of populated areas and are doing a km class test of the laser. The receiver is at a km class height from the ground station for this test.

Any feedback on our test setup—or advice on how to make sure we don’t accidentally destroy a multi-million-dollar device—would be deeply appreciated!
