Install Docker in WSL 2 without Docker Desktop — Nick Janetakis

It's really fast and only requires a few lines of shell scripting. You won't need to run systemd inside of WSL 2 either.

RSA keys are not deprecated; SHA-1 signature scheme is!

To avoid having to deal with further issues relating to RSA keys, I've decided to migrate all my SSH keys to Ed25519.

Potential issues with RSA keys

  • Key length growth: Will gradually require more bits to stay secure as compute capacity advances (Current minimum: 2048 bits)
  • Not future proof: Potentially vulnerable to breaking by quantum computers
    Advantages of Ed25519 (EdDSA) keys:
  • Performance: Ed25519 is the fastest performing algorithm across all metrics
  • Security: EdDSA provides the highest security level as compared to other algorithms with the same key length (Source)
  • Dummy proof: No need to specify number of bits when generating keys
  • Shorter public keys: No wrangling with unwieldily long public key strings like in RSA 4096-bit

For context, 253 bits EdDSA is equivalent in strength to RSA ~3000 bits. As you can see, Ed25519 blows all other cryptographic algorithms out the water in terms of performance.

Instead of Fighting Antisemitism, Harvard Sues Trump Admin—and Some Jewish Students Are Appalled – RedState

Many Jewish students are disgusted with the university’s behavior:

Harvard students and alumni are speaking out after the university announced it is suing the Trump administration rather than comply with its demands to address antisemitism on its campus.

"The government withheld funds from racist schools that refused to integrate. The Obama administration repeatedly threatened to withhold federal funds to sexist schools that refused to combat sexual assault. The Trump Administration's efforts are in no way an unprecedented threat on higher education. Should Harvard still like to enjoy American taxpayer money, they can simply choose to comply with federal law at any point," Harvard student Shabbos Kestenbaum told Fox News Digital. //

Jews Fight Back 🇺🇸🇮🇱 @JewsFightBack

Every time someone says “as a Jew” right before minimizing Jew-hatred or covering for institutions that enable it, antisemites everywhere breathe a collective sigh of relief.

Alan Garber isn’t speaking as a Jew.
He’s speaking as a coward.

Beth Israel Hospital in Boston was founded in 1916 by the city’s Jewish community to address significant barriers faced by Jewish immigrants and Jewish medical professionals during an era marked by religious separatism and widespread anti-Semitism. At the time, Jewish patients and physicians often encountered discrimination at other hospitals, which limited both access to care and professional opportunities.

Get started with Docker containers on WSL | Microsoft Learn

This step-by-step guide will help you get started developing with remote containers by setting up Docker Desktop for Windows with WSL 2 (Windows Subsystem for Linux, version 2).

Docker Desktop for Windows provides a development environment for building, shipping, and running dockerized apps. By enabling the WSL 2 based engine, you can run both Linux and Windows containers in Docker Desktop on the same machine.

The Factory Called School: How America’s Education System Was Engineered for Obedience, Not Excellence - American Free News Network

America’s education system wasn’t designed to unlock the genius in every child. It was designed to produce compliance. Efficiency. Predictability. In short—factory workers, not thinkers.

This isn’t a conspiracy theory. It’s a matter of historical record.

The Industrial Blueprint

In the late 1800s and early 1900s, as the U.S. surged into the Industrial Revolution, it looked a lot like today’s China—a manufacturing behemoth. Industrialists like Andrew Carnegie and John D. Rockefeller understood that in order to fuel mass production, they didn’t need philosophers or inventors. They needed disciplined laborers who could follow instructions, show up on time, and never question authority.

So the school system was modeled on the factory floor:

  • Rows of desks like assembly lines
  • Bells to simulate shift changes
  • Subjects taught in isolation, with minimal cross-disciplinary thought
  • One-size-fits-all learning geared toward standardization, not inspiration

Horace Mann and John Dewey—often celebrated as pioneers—helped usher in this system. Dewey even said: “The teacher is not in the school to impose certain ideas or to form certain habits in the child, but is there as a member of the community to select the influences which shall affect the child and assist him in properly responding to these influences.” In other words, social conditioning, not personal discovery. //

It’s time to unplug the conveyor belt.

Let’s stop pretending our schools are sacred. Let’s start building a system that grows free minds, not gray-suited cogs.

Because our children aren’t factory products.

They’re image-bearers of God—capable of wonder, wisdom, and greatness. If we don’t fight for their minds, someone else will program them.

Study: Media Gaslights Americans With Misleading Term for Illegal Immigrant Gangbanger Over 500 Times – RedState

Is he a "Maryland father?" No, he's an illegal alien who's lived in the U.S. for years and has never made any attempt to become a citizen. Is he an American citizen who was unlawfully deported? No, he’s in this country illegally and had a valid deportation order issued against him. (It is true that he wasn’t supposed to be deported to El Salvador because he was fearful of opposing gangs, but he is not and never was an American citizen. //

CNN and MSNBC referred to Kilmar Abrego Garcia as a “Maryland man” or similar terminology a total of 506 times in three weeks.

Garcia was described as being from Maryland nearly five times more often than he was described as being from El Salvador.

Only 10% of the 318 reports about Garcia on both networks included any mention that he was in the U.S. illegally.

Talking heads on MSNBC were almost twice as likely to misrepresent Garcia’s immigration status as they were to describe it correctly.

Introducing MikroWizard: An Open-Source Solution for MikroTik Router Management - MikroTik

MikroWizard is designed to help MikroTik users monitor and manage their routers from an IT administrator's viewpoint. Beyond being merely a monitoring and management tool, it functions as a complete management solution that offers PAM-like capabilities specifically for MikroTik devices.

Before developing MikroWizard, which originated from a customer request, I explored existing central management software for MikroTik devices. While "Dude" and other free or commercial tools are available, they didn’t meet my requirements. Many commercial options looked promising but posed security concerns, as trusting a cloud provider to access our network—or relying on the internet for server access—was not an acceptable risk, also they are not offering what I actually looking for.

Here’s what I was searching for MikroTik Managment:
✔ The ability to manage all users who access MikroTik devices, including coworkers, admins, support center staff, customers, and even IT administrators themselves.
✔ A logging system to track all actions performed by admins, customers, and support operators on the router, with historical data showing who made changes and when—similar to the logs provided in PAM solutions.
✔ Centralized creation and editing of system users and groups.
✔ Scheduled firmware updates without requiring internet access on MikroTik routers.
✔ A syslog grabbing and storage feature with filtering and search capabilities.
✔ A centralized, reliable backup solution with differential backups and scheduling options.

shock waves - Why do shockwaves extend past the body that created them? - Aviation Stack Exchange

Why do shockwaves extend past the body that created them? As seen in this photo, the shock doesn’t stop in the air the plane is effecting, but continues on. I always assumed it was high pressure air from the shock extending out, but now I’m not too sure. //

Shocks are not because of the pressure. Shocks happen because of the turning -- the pressure jump is a result of the shock. – Rob McDonald Mar 14, 2024 at 17:27

aerodynamics - Why does a shockwave from an aircraft at 30,000 feet reach the ground if it's only going Mach 1 at altitude? - Aviation Stack Exchange

A shock wave generated at 30,000 feet at Mach 1 cannot be heard on the ground for precisely the reason you surmise in your comment.

The US Air Force has conducted tests with supersonic aircraft and has this to say:

Under standard atmospheric conditions, air temperature decreases with increased altitude. For example, when sea-level temperature is 58 degrees Fahrenheit, the temperature at 30,000 feet drops to minus 49 degrees Fahrenheit. This temperature gradient helps bend the sound waves upward. Therefore, for a boom to reach the ground, the aircraft speed relative to the ground must be greater than the speed of sound at the ground. For example, the speed of sound at 30,000 feet is about 670 miles per hour, but an aircraft must travel at least 750 miles per hour (Mach 1.12, where Mach 1 equals the speed of sound) for a boom to be heard on the ground.
