A weekly dose of all thing Linux and open source with a slice of Pi for good measure.



Colour key – Venn Jill Pedro


  • Ubuntu 18.04.2 has been released with several important upgrades.
  • Ubuntu 18.04.2 LTS ships with Ubuntu 18.10 Cosmic Cuttlefish graphics stack and the 4.18 Linux kernel, so we will get a new kernel and updated Xserver, Wayland and Mesa drivers.
  • Ten year support cycle for Ubuntu 18.04, till 2028!
  • Like we talked about last week, it was postponed a week due to a boot bug.
  • This of course also applies to all the distros which use the LTS as a base.
  • So if you’re running KDE Neon and want that newer kernel or mesa without resorting to PPAs, now you can haz.
  • “All these have already been battle-tested in Ubuntu 18.10”
    • I would argue this.


Kali 2019

  • Metasploit 5.0 is a massive update that includes database and automation APIs, new evasion capabilities, and usability improvements throughout.
  • 2019.1 also includes updated packages for theHarvester, DBeaver.
  • here are no longer separate Raspberry Pi images for users with TFT LCDs because reasons.
  • Banana Pi and Banana Pro can now enjoy 4.19 goodness.
  • Metasploit hasn’t had a major release since 2011.
    • …hasn’t seen a major release since 2011.*
  • This is just the major version number bump.
  • In fact, if you install Metasploit from your distro repo, you’ll see an update for it daily.


76 Lappys

  • I kinda wanna look at that 17.3” panel running at 144Hz.
  • Pricing starts at a “modest” $2’000!
  • As someone who carries around a portable workstation, an Asus ROG 17.3 inch laptop, or what I like to call my beast, the Servel would be good for me!
  • I use it for my animation work and for remote broadcasts on LGC.


So it begins

  • AMD better be taking notes. <-
  • A little bit of code to introduce the concept of different memory regions, and a simple buddy allocator to manage them.
  • It’s going to be interesting to see what comes from a ground-up discrete GPU implementation.
  • Intel understands where the money is, in calculating big data and rendering in Linux.
  • Better and more efficient memory calculation is the future of GPUs, just as multicore processing was for CPUs.


Spider Colour

  • We’ve mentioned the Academy Software Foundation before.
  • OpenColorIO has been free to the public but now the ownership has moved to the ASF.
  • Used to create movies like “Spider-Man: Into the Spider-Verse,” “Hotel Transylvania 3,” “Alice in Wonderland” and “Cloudy with a Chance of Meatballs” to the open source community.
  • A color management framework for visual effects and animation.
  • OpenColorIO is natively supported in Blender.
  • OpenEXR is another project due up on the list.
  • This is exactly why the ASWF was formed, to help unify, advance and help with software licensing for open source software in the TV/film industry.
  • OpenColorIO is the animation and visual effects equivalent to the Adobe and the Pantone color management systems for digital photography, printing, paints etc.
  • Supports all the popular Foundry software used in the industry, including Nuke, Modo, Katana, and Mari animation and visual effects software.  Many of which I use and teach.
  • All the Foundry animation software, and most of the other industry standards used in the film industry is run and rendered in CentOS/RHEL 6 Linux!  Many now support Ubuntu as well.
  • I like this trend! More of this please!


Pulse Effects

  • Almost a year ago we talked about Pulse effects
  • Now it comes back with automatic sink detection and it applies the effects you had previously set for it.
  • A new graphics equalizer with options to show/hide bars borders in the spectrum and to change their line widths, as well as a switch to enable/disable linear gradient.
  • Limiter, compressor, reverberation, equalizer and auto volume effects for Pulseaudio applications.
  • It’s like a stripped down set of Calf Studio Plugins for pulse without the hassle of install Jack.


Back in my day

  • For those of you who consider Slackware the new kid.
  • Yggdrasil, basically implementing the Ubuntu and WINE philosophies before either of these were a thing.
  • These are the earliest Linux distros, the one’s who started it all, before our mainstream distros we all know and love came to being.
  • Starting back in 1992, the first known distro-like tools to get access to Linux were released by HJ Lu on two 5.25” floppy disks.
    • HJ Lu, or Linux 0.12, consisted of a “boot” disk and a “root” disk.
    • To install it on a hard drive you had to edit the master boot record with a hex editor.
  • TAMU Linux was the first Linux distribution to include the X Window System, instead of text based, and was developed in May 1992 by the Texas A&M Unix & Linux Users Group.
  • Still have my copy of TAMU Linux on floppies that I downloaded from my brothers BBS.  Lots of the early Linux distros could be found on BBSs, including LInus Torvald’s first prototypes of LInux.

Slice of Pi

Redmond Pi

  • You don’t necessarily buy Pi’s for the desktop experience.
  • And you certainly don’t get a Pi to run Windows.
  • This is just more evidence to that.


Hot Pi’s

  • Not overclocking your Pi also has the benefit of it living longer.
  • Do you want your RasPi B+ to catch on fire? ;-)
  • $35 devices, melt them.
