The answer that I do this for *work*, I do not think it is *fun*, or a *hobby*, and I will never in my life troubleshoot an #ActiveDirectory problem unless I am getting paid for it, was not what he expected.

I did something crazy - and it works.
And I think in the next few days, I'll also do the crazy thing of making it public. I think some people will like it.
Because - I'll say it again - I'm always against monocultures.

Stay tuned!

Serving a simple website from a Jail with Bastille

A great article by @jhx for the BSD Cafe Journal!

I've never hidden my admiration for #illumos-based systems. I have a few setups based on #OmniOS and #SmartOS, and they're solid as a rock. I like them both: OmniOS is more "malleable", while SmartOS is more of a hypervisor like #xcp-ng or #xen - meaning you install it on the host and delegate everything else to the zones.

I also love #FreeBSD jails, but zones sometimes cover use cases that jails can't (and vice versa). For example, imposing RAM limits in jails works, but it effectively "denies more ram" to a process when it requests more memory. The end user doesn't see this directly. On illumos, the user sees everything. I have some `lx` zones with Debian and Virtualmin, and users have never noticed that they aren't really on #Linux. A free or top will show only the assigned RAM.

And that's one of the biggest problems with open-source operating systems: they all have something good, and I always feel the urge to use them all! 🙂

"This paper presents implementations that match and, where possible, exceed current quantum factorisation records using a VIC-20 8-bit home computer from 1981, an abacus, and a dog.

We hope that this work will inspire future efforts to match any further quantum factorisation records, should they arise."

Note that this is three attempts to match current quantum computing records, not a single attempt utilizing all three tools.

My home desktop - 1 March 2000 - a Pentium 233 MMX.
The OS was Debian Linux - you can see a printed Tux near the keyboard.
No broadband connection, just a 56k modem.
Iomega Zip drive - so I could download stuff at Uni and bring it back home.
One year later, this became my first 24/7 server.

When I open a project's web page and find a guide to deploy it with Docker and also without it, I'm already liking that project.

AWS Deleted all data despite redundancy, backup, dead man’s switch. This is why you need to keep all your data offline. The 3-2-1 backup rule is a good data protection strategy that states that you kee 3 copies of your data, storing them on 2 different types of storage media, and keeping 1 copy offsite under your bed or office. Don't trust your hosting company's backup service.

Thanks to @s3phy again for helping me understand another area where IPv6 is broken in Linux desktop networking configuration tools: connecting to a SSH server to create a SOCKS proxy using the NetworkManager SSH plugin. That thing only checks if the gateway address is a valid IPv4 address

I reported the issue here: https://github.com/danfruehauf/NetworkManager-ssh/issues/130

I thought my colleague was an alien who decoded base64 strings on the fly, but he wasn't.

It turns out there's a neat little trick to know that you're looking at a base64 encoded JSON object.
