Stefano MarinelliLast night I dreamed I was buying new servers, European ones, based on ARM architecture (or maybe RISC-V, I don’t remember – I just know it wasn’t the 'classic' amd64). Just a dream, or is there actually something interesting already on the market?<a href="https://mastodon.bsd.cafe/tags/SysAdmin" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SysAdmin</a> <a href="https://mastodon.bsd.cafe/tags/IT" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#IT</a> <a href="https://mastodon.bsd.cafe/tags/Server" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Server</a> <a href="https://mastodon.bsd.cafe/tags/Hardware" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Hardware</a>

My Actual BrainI see a lot of books/tutorials about mysql. Can I use those to understand mariadb? It seems that I can, it also seems that mariadb is preferred to mysql.If anyone has any good sources to learn more about databases, I would love to hear them. I am just getting started with them.I'll mainly be using it to hold text and numbers.<a href="https://fosstodon.org/tags/homelab" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#homelab</a> <a href="https://fosstodon.org/tags/linux" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#linux</a> <a href="https://fosstodon.org/tags/SysAdmin" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SysAdmin</a> <a href="https://fosstodon.org/tags/selfhosting" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#selfhosting</a>

Mike ElyWas looking over the breakout sessions at <a href="https://social.taupehat.com/tags/RedHat" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#RedHat</a> Summit, and sure enough... I suspect this is mandatory at every big FOSS event. Every year for decades now I've seen this session, and however much I might wish this were the year I can reasonably expect to see the session come back in 2026. <a href="https://social.taupehat.com/tags/sysadmin" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#sysadmin</a>

Abnormal Human BeingSo, I am stuck trying to apply the current <a href="https://toots.abnormalbeings.space/tags/Mastodon" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Mastodon</a> update. Note that there may be many good reasons why, chief among them, that I am self-taught and very much in the "trying stuff out half-blindly while learning"-stage.

Stefano MarinelliOk, maybe I should wait a bit, but I feel like giving a little preview, incomplete...

TomThis is a CPU graph of a web host that began having AI bots absolutely slam it starting at 4am UTC.I blocked all Chrome user agents older than 120 at about 10:45 UTC.These AI bots aren't using "nice" names like ChatGPT or AmazonBot. No, more like Chrome/116 or similar and they come from ALL OVER.I am so tempted to put Iocaine or Nepenthes on the machine to generate Markov Chain garbage to poison the well, but I'd have to have Nginx map the older user agent string with regex. It probably could be done but this might piss off my employer. 😂<a href="https://mastodon.bsd.cafe/tags/SysAdmin" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SysAdmin</a> <a href="https://mastodon.bsd.cafe/tags/AIbots" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#AIbots</a> <a href="https://mastodon.bsd.cafe/tags/FuckAI" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FuckAI</a>

Jeff HortonOk, I'll admit. I spent too much time wondering why I couldn't SSH into a server before I realized my IP had changed during my speed upgrade AND I was using the VPS cloud firewall to limit access to the old IP.<a href="https://mstdn.ca/tags/sysadmin" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#sysadmin</a>

nickbeardedman7.org is an invaluable resource for Linux users, providing comprehensive and up-to-date man pages with clear, detailed explanations of commands and system tools. It’s a must-visit for anyone working in the terminal, and the effort put in by the curator is truly appreciated.

Stefano MarinelliFor many years, I’ve been silent - but I’ve been doing a lot. Some of it I’ve shared, some I will. One project has already been partially revealed: ITNBlog, my Python-based static site generator that’s been quietly building my blog for a while now. I haven’t (yet) published the code - it’s not exactly beautiful (I’m no coder, and it’s not a daemon, it just spits out HTML) - but there’s some info here: <a href="https://itnblog.dragas.net" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://itnblog.dragas.net</a>But there’s another “program” (though calling it that says a lot about my approach 😄), which I started back in 2015 for personal use - and I’ve been using it ever since. Over the years, I’ve expanded and reshaped it so much that it’s grown into something big. Big enough that some people might raise an eyebrow at how it’s structured. But it works. And considering everything, it’s efficient enough. Plus, it has a little bonus that I think some of you will appreciate.I’ve used it for years on macOS and FreeBSD. This morning, I re-tested it on OpenBSD - and it ran flawlessly, thanks to the OS’s rock-solid stability. It also works on Linux, and I plan to try it again on NetBSD - though I’m pretty sure it’ll be fine there too.I’m considering releasing it before ITNBlog - but I’d like some time to review it properly. Still, I think it’s coming soon… and it might be a curious little surprise 😉 Stay tuned!<a href="https://mastodon.bsd.cafe/tags/IT" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#IT</a> <a href="https://mastodon.bsd.cafe/tags/SysAdmin" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SysAdmin</a> <a href="https://mastodon.bsd.cafe/tags/NewNiceThingsAreComing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#NewNiceThingsAreComing</a>

George Ellenburg (he/him/his)And it's not like the Terminal app in <a href="https://bofh.social/tags/Webmin" rel="nofollow noopener noreferrer" target="_blank">#Webmin</a> isn't capable. It handles the complex full UTF/ ANSI output of <code>btop</code> just fine! <a href="https://bofh.social/tags/sysadmin" rel="nofollow noopener noreferrer" target="_blank">#sysadmin</a>

George Ellenburg (he/him/his)I should also point out that <a href="https://bofh.social/tags/Webmin" rel="nofollow noopener noreferrer" target="_blank">#Webmin</a> is not exposed to the open internet. It used to be, before I installed <a href="https://bofh.social/tags/Tailscale" rel="nofollow noopener noreferrer" target="_blank">#Tailscale</a>, and back then every account required <a href="https://bofh.social/tags/MFA" rel="nofollow noopener noreferrer" target="_blank">#MFA</a>, but since I've transitioned to Tailscale for my intranet for all my servers both at home and remote Webmin is now only exposed to my <a href="https://bofh.social/tags/Tailnet" rel="nofollow noopener noreferrer" target="_blank">#Tailnet</a>. Which means that if Tailscale doesn't come up for some reason I need to login to the server console (royal pain in the ass but still.) <a href="https://bofh.social/tags/sysadmin" rel="nofollow noopener noreferrer" target="_blank">#sysadmin</a> <a href="https://bofh.social/tags/linux" rel="nofollow noopener noreferrer" target="_blank">#linux</a>

George Ellenburg (he/him/his)Hands down the Number One reason I install <a href="https://bofh.social/tags/Webmin" rel="nofollow noopener noreferrer" target="_blank">#Webmin</a> on every single one of my servers... Not because I don't know how to <a href="https://bofh.social/tags/sysadmin" rel="nofollow noopener noreferrer" target="_blank">#sysadmin</a> a server (been doing it since 1992) but for this one single feature: (so much more convenient than ssh'ing into my remote servers)

JustinGah. Spinning wheels of zero progress for hours on end. How is Microsoft still.. why.. why? They've had decades to get better at building operating systems & yet updates still frequently freeze up and systems are *wildly inept* at displaying a modestly accurate progress bar. It's actually sort of impressive how much Windows continues to suck.
