Won’t this delete the two newest files, as opposed to everything except the two newest files?

I just looked up the man page, and actually head -n -2 means “everything up to but not including the last two lines”, so this should always leave two files remaining.

Ah! This is a shell pipe! It’s composing several smaller commands together, cool stuff.

• ls -1 is the grep-friendly version of ls, it prints one entry per line, like a shopping list.

• head takes a set number of entries from the head of a list, in this case 2 items. negative two, meaning “all but the last two.”

• xargs takes the incoming pipe and converts it into extra arguments, in this case applying those arguments to rm.

So, combined, this says “list all the .dump files, pick the first two, all but the last two, and delete them.” Presumably the first are the oldest ones and the last are the newest, if the .dump files are named chronologically.

I agree with you but your tone is way too violent, we should be helping people learn from their mistakes, not infantilizing them.

True… the trouble with open source is that nobody’s getting paid to add features you want, huh.

I’m excited! But why not Minetest? :p

this is my current solution; I use Obsidian to manage my notes and I sync the folder with Syncthing. I still use Google Keep though for its whiteboard tool; is there a better app for that?

where do you find good sources to follow, then?

updated post here, includes section on networking! let me know if this looks good? https://lemmy.world/post/2444639

ah, thank you! it’s actually been long enough that I created a new post here: https://lemmy.world/post/2444639

Very high praise! Let me know what they find helpful or frustrating!

ah, well spotted! I’ll fix that, whoops

Hear hear! I thought I didn’t like the fediverse because Mastodon did such an awful job selling it to me. “Oh, I can’t view other instances’ local timelines without making accounts on them? What’s even the point of federation then?” But on Lemmy you can easily browse communities outside your own instance. So it’s not the fediverse’s fault, Mastodon just doesn’t have a clear audience.

And yeah, I can see how a lot of Mastodon’s features are “privacy-focused”, but I think it does TOO good a job, it’s so private that you can’t find anything!

in a word, intersectionality. you’re getting people who were already looking for an excuse to ditch reddit and twitter, and of that group, you’re selecting the ones with the most tech literacy. That tends to overlap people with progressive politics.

I’ve changed my naming scheme so many times that its practically a set-of-sets at this point. But, “board games” is a good long one if you have a lot of machines.

I add .env to my .gitignore, then I can safely put secrets in my .env. If you have a big .env file, make a sample.env with the secrets removed.

actually, could you tell me more? not only are those new solutions to me, those are new problems. I don’t even know how to tell if uPnP is turned on.

edit: oh! I have actually dealt with NAT reflection before, the guide I used called it Hairpin NAT. https://help.mikrotik.com/docs/display/ROS/NAT#NAT-HairpinNAT

I wish I had a better guide on that myself! I’ve been using this guide for the time being, it covers the basics of how to set up a firewall: https://www.raspberrypi.com/documentation/computers/configuration.html#securing-your-raspberry-pi
