It doesn’t appear to be much discussed but you can perform secure boot of UEFI clients from a Cobbler build server. We managed it recently, under pain of needing to install Ubuntu on 400 Dell laptops before an imminent start-of-term deadline, and with only a modicum of dirty hacks.
Here’s early 70s prog band Skin Alley playing Norway’s Ragnarock Festival in June 1973, the only live footage I can find from their short career:
Ansible now contains a decent set of modules for managing virtual machines in VMware vSphere. As ever with Ansible, the key is not so much in knowing how to use these modules (which the docs explain fairly clearly) as in knowing how to organise the playbooks that call them. Here’s one example based on our own recent practice.
This is a quick summary of how best to set up and use Darktable for processing raw files from the Panasonic DMC-GX80 (GX85 in USA).
For reference, I’m using Fedora 28 with the current Darktable 2.6.0 release. I mainly shoot landscapes or architecture, so some of the following may not apply if you’re a portrait photographer.
Problem: In this scenario, we have a potentially long list of usernames (accounts) and a directory containing SSH public keys, one per file with each file named after the user that owns that key. We want to deploy all the keys for the users in our list.
Many of the Ansible roles we write are concerned with installing and managing the configuration of a particular application or package. For example, we have a role that installs PHP and configures particular settings in the php.ini file according to a Jinja2 template.
Finally filled my 1TB NAS file server this year, to the point where the 30GB of images I brought back from New Zealand (oh-by-the-way, did-I-mention-we-went-to-NZ?) could not be dumped to disk, let alone processed. So it was time to exchange the two Samsung hard drives composing the mirrored data storage for new 2TB drives. I’m using ZFS on OpenIndiana - this should be easy, right?
Running down ten years of the MCU
Although they’re not making a huge fuss of it compared to the upcoming release of Avengers: Infinity Whoar, this year marks a decade of the Marvel Cinematic Universe, from its initial conception as a gleam in Nick Fury’s one good eye, in a post-credits sting tacked on to 2008’s Iron Man. So just like Marvel and, seemingly, everyone else, I thought I’d be totally original and do a list of all the films rated definitively and non-derivatively according to my own very personal criteria, which will almost certainly be completely unlike all the other lists because there’s a lot of scope for major disagreement when sizing up the relative merits of, say, The Avengers and The Incredible Hulk. (That last sentence, incidentally, was originally supposed to be a subplot in Age Of Ultron but got cut for being too wordy and syllable-ly at the studio’s insistence, like virtually everything else that made sense in the script.)
