Video: A Greybeard's Worst Nightmare (Updated)

Submitted by Scott Dowdle on Sat, 04/20/2019 - 09:31

Trying to wrap one's head around the paradigm changes happening in the industry can be difficult.  Everything is just moving way too fast.  Daniel Riek has been giving a talk for a while now entitled, "A Greybeard's Worst Nightmare."  Here is a fairly recent iteration of his talk where he does an excellent job of providing both a historical context and a bridge to understanding the revolution and evolution that is happening.  Unfortunately a lot of the progress has been coming from black box services provided by proprietary companies who don't see lock-in as a problem.  Daniel explains how the benefits that have been gained by adopting free and open source software don't have to be abandoned in an effort to keep up with industry methodology shifts providing the most innovation and value.  We can and are keeping up... but there is a LOT to learn.

 

Video: LabX and the GUI web-based desktop

I signed up for a free service a few weeks back named LabX. I don't remember where I learned about it... some article I saw posted on LXer I think. Anyway... today I got an email invite from them, signed up for an account and gave it a try.

To be honest I don't know much about it yet and I don't know exactly what it is for and what to do with it... but one this is for sure, I like virtualization and remoting protocols... so it is right up my alley. After creating an account I logged in. Turns out the email address you registered with is your username although that isn't exactly clear from the various screens. Once logged in I was able to start and access a virtual environment that was listed as "Ubuntu 14.04". Connecting to it gave me a GUI desktop in my browser. XFCE / Xubuntu. I recorded a 15 minute screencast (no audio) of the session so enjoy.

Please note, the video is of my Firefox web-browser running on my local desktop and the shown browser tab is my connection to the remote GUI container. The raw video was 1276x1373 resolution and 566.7 MB in size (in .mkv format) but I used ffmpeg to resize it to 720x755 @ 400Kbit so it is now 13.8 MB (in webm format). Much smaller and a little blurry but much better for web streaming.

If you prefer to download and play in local media player, here's the direct URL:

Video: Containers with systemd

Linux Weekly News had a write-up in their Weekly Edition last week... of Lennart Poettering's talk (Containers with systemd) at LinuxCon Japan 2015. That article should be available freely later this week... but I found a recording of what appears to be the same talk at a different event from April 2015. Here are the slides. Enjoy!

For those with iFrame issues, here's the direct link:

Here's some documentation on that stuff if you are looking for it.

Want more? How about more of a hands-on approach? Gábor Nyers can provide more... in his presentation from the recent OpenSUSE Conference 2015.
