I've run our #DNS servers at #DEFCON for about 25 years, and before upgrading one of them I recorded some statistics some might find interesting.

Of all the DNS traffic for a given period:

74% by connection is IPv4
26% by connection is IPv6

2% is using TCP 853 encrypted DoT

31% uses TCP
69% uses UDP

Proper mail server with great trust & no fancy crap, just in/out, spf, dmarc, dkim (records & policies), PTR, and 10/10 score - no round cube or virtual mailboxes or web based tools - consider this elegant and yet powerful recipe I made (thanks to Linux Babe - lots of great tips). This recipe is ideal for small businesses, educators, and/or small to medium (50-200) communities. #sysadmin #freesoftware #gnulinux

🎵 Since you launched, I’ve been lost in your stack trace
I dream of literal strings that want to escape
I search the code for every hidden mistake
I feel a bit like I need a coffee break
I keep asking, server, server please!

Can I beat Mario with Vim controls?

👕 Buy the shirt:
❤️ Support the channel:
No video game is more iconic than Super Mario Bros.
No text editor is more iconic than Vim.

In today's platform-packed episode of Veronica Explains, I try my hand¹ at playing Super Mario Bros, but using Vim controls instead of a controller. I'll also talk briefly about the history of Vim and Vi, and show you how to configure FCEUX to use whatever keys you fancy.

Oh, and before I forget! "Mario" and "Super Mario Bros" are registered trademarks of Nintendo of America.

I've been tentatively tooting for a few days now, so I guess it's about time I did my #introduction !

Hi everyone. I'm a #library #SysAdmin for a UK university by day.

Outside of work I spend far too much time tinkering with #Linux and a collection of #SBCs (mainly #RaspberryPi ), but like to get out to do some #photograhy (mainly landscape & nature).

What seems like a lifetime ago I studied #physics at uni (I have since forgotten most of it!) with a real interest in #cosmology. I do get outside some nights for #astronomy 🔭 but I'm mainly a fair weather astronomer these days.

Also into #SciFi :blobcatspace:​ , #classicalmusic :blobcatmusic:​ and #tea :blobcattea:

Oh, and I'm not actually a sentient teapot!

Look forward to tooting with you! :blobcathug:

I suppose it's my turn for an intro! I'm a #retrocomputing #linux enthusiast in Western Australia.

Currently doing #sysadmin work, and in my spare time tinker with old computers, linux and electronics.

I've also /just finished/ writing a blog post about an old computer, the HX-20:

Good morning und guten Morgen!

OK, hi Fediverse, my name is Silke, I post much less than I did years ago, I don't even know which language I'd use here, I read in German, English, French, Polish. (And I'm trying to learn some Georgian right now.) I'm a #feminist, I like #photography and baking.

I work as a #linux #sysadmin, I love automation because my natural state is lazyness. 😉
