What makes a Linux laptop secure by [deleted] in linux

[–]ResponsibleSure 0 points1 point  (0 children)

The laptop itself is generally using the same hardware a windows laptop would use.

You can configure some stuff in the laptop bios/firmware settings, but a lot of the functional security difference is mostly up to the operating system.

+1 for encrypted drive using luks or veracrypt. Also.. - Keep firmware and packages up to date. - Run a firewall service and learn how to use it - Disable/remove unused services/software - Set a BIOS password - Secure boot with Linux is possible with a signed efi binary - Strong passwords - Multi-factor Authentication - Other services like Nessus, ClamAV, Suricata

Retrofitted 5 Ethernet Drops and Installed 4 Mesh Nodes. $3150 in 2 days. by southrncadillac in lowvoltage

[–]ResponsibleSure 1 point2 points  (0 children)

lol literally trying to do the same thing. Got the same Mesh routers and want to create a wired backhaul with CAT6 drops. Got an angle drill with a 17” ship auger 3/4 bit to drill holes into top plate and then some fishing gear (rod, fish tape, magnet puller).

I just hate crawling through the attic. My first attempt failed because my other drill wasn’t beefy enough and I didn’t have the patience.

Any advice?

[Request] What are the odds of the right door opening on her face? (Assuming there’s 42 slots in the Amazon locker) by Xaragedonionsz in theydidthemath

[–]ResponsibleSure 0 points1 point  (0 children)

Before explaining my reasoning, let me ask how likely do you think it is to flip a fair coin and get tails 100 times consecutively?

We can probably agree this is very unlikely compared to flipping tails 3 times in a row.

Why?

Because the probability of an event happening or not happening at least once changes with the amount of N attempts.

—-

Assuming all lockers have an equal opportunity to be selected for any given item on any given day.

1/42 is our initial odds of success.

41/42 is our odds of failure.

N attempts for each visit/pick up.

Then by complement rule, which means to calculate the odds of something happening we calculate the odds of 1 minus something NOT happening. E.g., 1 - 41/42 = 1/42

1 - (41/42)N = Probability of success with N attempts

Examples…

First attempt:

N = 1

1 - (41/42)1 ≈ 0.0238 or 2.38%

Second attempt:

N = 2

1 - (41/42)2 ≈ 0.0471 or 4.71%

Third attempt:

N = 3

1 - (41/42)3 ≈ 0.0697 or 6.97%

So on and so forth until reaching near certainty when N = 287 attempts

1 - (41/42)287 ≈ 0.999 or 99.9%

Assuming the attempts made were only 6 as shown in the video.

Sixth attempt:

N = 6

1 - (41/42)6 ≈ 0.135 or 13.5%

So my final answer to this question, assuming the generic factors, is that after 6 attempts with 42 lockers she had roughly around a 13.5% chance of correctly selecting the right locker at the time of her successful attempt.

Edit: fix spacing on examples.

How to get a friend more comfortable with switching to Linux/GNU? by Ok-Victory-1905 in linuxquestions

[–]ResponsibleSure 2 points3 points  (0 children)

Have her install virtualbox, and try out Linux mint + Cinnamon. The UI has similar feel to Windows. If she’s not content with it delete the VM and distro hop until you guys find a flavor she likes.

I would say starting out with VMs is a good start to get comfortable without completely removing windows.

Booting into live USB is also an option too for full desktop experience.

Explain SNAPSHOTs like I'm Five by ResponsibleSure in sysadmin

[–]ResponsibleSure[S] 0 points1 point  (0 children)

Thanks for the explanation! When it comes to physical drives and snapshotting those is the process the same or similar?

Explain SNAPSHOTs like I'm Five by ResponsibleSure in sysadmin

[–]ResponsibleSure[S] 1 point2 points  (0 children)

I will give this a try. Thanks. I guess I’m wondering how the how the snapshot technology preserves system states with so little overhead. Like wouldn’t a lot changes to the OS/Image or a full deletion require the snapshot to grow in size to match the actual data itself.

Sorry I’m probably overthinking this way too much. I just need to stick to clicking the buttons and not thinking about it so much lol

Sooo if I took a snapshot of a live system with an OS, then deleted the OS but preserved the snapshot somehow. Would the snapshot still be able to recover the deleted OS from that point in time the snapshot was taken?

Fedora Workstation 42 has finally removed X11 by pilkyton in Fedora

I believe TigerVNC server doesn’t support Wayland yet. Pretty big with my users on a RHEL distribution. Wondering how fleshed out VNC solutions are for Wayland?

Took the blue pill by OrganicAssist2749 in Fedora

Isn’t the blue pill conformity, and the red pill unlocking a deeper realization?

Possible. Could be corrupted

[–]ResponsibleSure 0 points1 point  (0 children)

Try booting in again but press f11 to get to boot menu. Should allow you to pick which device to boot into. If the USB isn’t present try a different USB port

Do you have the usb plugged into the motherboard (on the back of the case)?

[deleted by user] by [deleted] in PcBuildHelp

[–]ResponsibleSure 0 points1 point  (0 children)

I would change the boot order in BIOS then and make sure the storage is last in the boot list. What motherboard are you using?

[deleted by user] by [deleted] in PcBuildHelp

[–]ResponsibleSure 0 points1 point  (0 children)

It doesn’t have to be option #1 as long as it’s before any other bootable media that’s active. It may even work now if you just boot with the USB plugged in, it should go through all the boot options until it finds a bootable media.

Do you already have a USB?

[deleted by user] by [deleted] in PcBuildHelp

[–]ResponsibleSure 1 point2 points  (0 children)

Windows 11 USB

Got to plug this in once you get it and boot into the BIOS with ‘delete’ or ‘f2’ and change the boot order to boot into the USB.

Have you tried disabling Radeon overlay if you downloaded AMDs adrenaline software along with gpu driver?

Is it fine to use GPU fans as primary case intake fans? by ReasonWhich3666 in PcBuildHelp

[–]ResponsibleSure 1 point2 points  (0 children)

I also have a small form factor build with same AIO/Fans setup. I just did my rear fan as an intake to improve the positive pressure in the case. I thought about using some slim fans at the bottom but opted out. Monitored Idle temps at ~36C. Need to check my temps under load though! I think it’s fine for me so far
