Is your #coffee not waking you? Try this:

 
So I went with DNSimple after looking at a few different companies. Initial experience is good, I like their ethos, and their support is friendly. Here’s a referral link if anyone is interested (we both get $5 credit if you sign up).

My DNS is all now managed with #Terraform (this provider), stored in Git, with the Terraform state file in Nextcloud so I can safely edit on multiple machines. They have good APIs so all sorts of automation is possible if that’s your thing (hey, it's 2018 - it should be your thing!).

The real power of Linux executables

What happens when a file gets executed in Linux? What does it mean that a file is executable? Can we only execute compiled binaries? What about shell scripts then? If I can execute shell scripts, what else can I execute? In this article we will try to answer those questions.

Nice and thorough description of what's happening under the hood when Linux executes a binary (or anything else.)

Aus dem Alltag eines #Sysadmin: Hochgenaue #Systemzeit


Von Charly Kühnast

Nachdem die Anschaffung einer Atomuhr im Hause Kühnast keine Mehrheit gefunden hat, zapft Charly eben das Uhrwerk eines GPS-Satelliten an. So verschafft er zu Hause der Pünktlichkeit Geltung, die sonst nur große Rechenzentren benötigen. Genau...

OK #podmin and #linux #sysadmin people. I figure there will be some good recommendations here. I run a few VMs at home on some outdated hardware. It's time to upgrade them. Xen is my hypervisor, and I'm currently running on an old HP XW8600 workstation. That gives you an idea of the kind of hardware I need: 8 CPUs, 32G of RAM. I do LVM for RAID. Main thing I'm looking to upgrade is the CPU quality. My current CPUs are Xeon E5450s, which lack a lot of the virtualisation support of more modern CPUs. But this is a desktop form factor, which I like. I don't need rack-mounted, dual power supplies and all that. Just a beefy, high-end desktop with the right CPUs would do. The beauty of using an older all-in-one box like this, is that they're easy and cheap to come by secondhand on eBay and such.

So the question is: can anyone name a desktop form-factor, 8-core (or more, I guess) box that's 2-3 years old and easy to find secondhand on eBay and similar sites? Oh, and I need it in the UK. So cheap US-based resellers really aren't helpful. Thanks.
 
Currently I have one big server to handle all my web app needs, including DB, Redis, etc to support those. It's becoming a bit bogged down due to I/O. So, planning to spread out a bit.

What I can't decide is whether to have one #Postgres DB for all the apps on a larger server OR have multiple (smaller) servers and a #Docker Postgres for each app separately on the same server.

Opinions? :)

Hi, everyone. I'm #newhere . I'm from #stlouis #missouri . I was invited here by a #burner #burningman friend and I came here for pretty much the same reason other people are migrating here for, because of all the #facebook bullshit. I'm not gonna do a hashtag dump because that'd be annoying, but some of the things I'm interested in are #writing , #rpg , #geek , #technology , #sysadmin , #gaming , #improv , #comics , #reddit , #history , #science, #technology , #news , #trance , #techno , #housemusic , #movies , #linux , and #marvelcomics .

In retrospect, that was probably a bit of a hashtag dump.

Anyway, tell me what I need to know, and if I seem interesting, hit me up.
 
Hey everyone, I’m #newhere. I’m interested in #devops, #diaspora, #floss, #linux, #philippines, #sysad, and #sysadmin.

Trying to get my own pod running, so I can eventually share this with families and friends.

Been playing with netdata this past weekend. Pretty slick system monitoring that's lightweight on system resources. It doesn't have much for looking at long term history though (at the moment at least). It does send notifications (via email, slack, etc...) which are quite handy. It currently won't replace #monitorix for me though due to the lack of history.
