atzanteol , to news in Trump supporters call for riots and violent retribution after verdict

Good question. If there aren’t arrests perhaps there were no crimes. Just things you want to be crimes.

atzanteol , to linux in How come Windows and macOS users don't have to enter their password every time they need administrator privileges?

Windows is historically a “single user OS” whereas Linux is historically a multi-user OS. They’re both multi-user now but the philosophy of these backgrounds results in what you see today.

So under Windows you login “as an admin” and don’t need passwords for many things - similar to (but very much not the same as) running Linux as root.

Under Linux you login “as a user” and need to elevate permissions for things which can affect other users on the same system. Typically with sudo these days.

These lines are very much blurring so you can do many things under Linux without a password and some things on Windows require “running powershell as an admin”.

Waiting for them to actually commit a crime is usually necessary.

atzanteol , to linux in Building and distributing binaries

Using containers for build environments is probably my favorite use of containers.

I have an application I build for Linux, Mac and Windows and frankly building two or three Linux builds in containers is easier than the Windows and Mac builds alone. A github action automates it easily.

atzanteol , to linux in Canonical Announces Availability of Real-Time Kernel for Ubuntu 24.04 LTS - 9to5Linux

I guess i am still skipping on how real time kernel address the pause? it just never pauses or it no longer needs to be paused?

When hardware has data ready for a program it generates an interrupt that lets the OS know that there is data ready for an application. My understanding is that real-time OSs give high priority to interrupts so that they’re processed quickly - usually within a fixed period of time (e.g. they may have a max time between interrupt and processing).

as a side note, is this similar technology they use in high precision manufacturing?

In those cases it may be more likely they use a micro-controller that doesn’t run any OS at all - at least not a multi-tasking one. If you’re just running a single program you don’t need to worry about latency due to other applications running.

So, contrary to what it seems a single CPU core can only execute a single “thing” at a time. Modern operating systems do something called “preemptive multitasking” to give the illusion that more than one things are running at a time. The OS will start your task, then after a while save its state and start another task running, then switch back. It does this fast enough that each job seems to be running concurrently.

Now if you’re running on a RaspberryPI your program might be waiting for input from a GPIO pin. And when you get that input you want to turn on some switch. Maybe an important switch. BUT It could be that your application is in the “paused” state when that pin gets input which will cause a delay between when the pin is trying to send you input and when you actually process it.

A real-time OS minimizes such delays (latency) so that you can respond quickly.

Which distro?

atzanteol , to linux in A screen recorder in the Browser?

Feature creep is a hallmark of “software bloat”. Using a web browser to do something completely unrelated to it’s core functionality is pretty much the definition of “bloat”.

Obs is purpose-built to do the thing you want to do. That it also has features you don’t want does not make it “bloated”.

atzanteol , to linux in Remote desktop for Wayland?

I’ve always liked “nomachine” for remote desktop access. It seems to support Wayland.

What should I do?

Let them do what they want.

atzanteol , to selfhosted in Is it safe to open a forgejo git ssh port in my router?

You’re right, but only if you are an experienced IT guy in enteprise environnement. Most users (myself included) on Lemmy do not have the necessary skills/hardware to properly configure and protect their networking system, thats way I consider something like wireguard way more secure than opening an SSH port.

But it doesn’t help to just tell newbs that “THAT’S INSECURE” without providing context. It 1) reinforces the idea that security “is a thing” rather than “something you do” and 2) doesn’t give them any further reference for learning.

It’s why some people in this community think that putting a nginx proxy in front of their webapp somehow increases their security posture. Because you don’t have “direct access” to the webapp. It’s ridiculous.

Sure SSH key based configuration is also doing a great job but there is way more error prone configuration with an SSH connection than a wireguard tunnel.

In this case it’s handled by forgejo.

atzanteol , to linux in A screen recorder in the Browser?

I guess the word “bloat” has no meaning anymore.

atzanteol , to linux in A screen recorder in the Browser?

OBS is extremely bloated for simple screen recording.

And a browser isn’t??

atzanteol , to programming in Why does every REST testing software want me to login?

Seems dead now. ☹️

atzanteol , to selfhosted in Is it safe to open a forgejo git ssh port in my router?

Wait, so you have the full website exposed to the Internet and you’re concerned about enabling ssh access? Because of the two ssh would likely be the more secure.

But either are probably “fine” so long as you have only trusted users using the site.
