Sudo panic!

  • Joe Vennix from Apple security found a nasty little sudo bug that probably doesn’t affect you. 
  • Unless you run Mint, do people still run Mint in 2020?
  • The flaw can only be exploited when the “pwfeedback” option is enabled in the sudoers configuration file.
  • If you run Mint, and see *******, panic… slightly. 
  • sudo -l and see if it pops up under Matching Defaults. 


Redhat CEO 

  • Wow, so I expected that Jim Whitehurst would change roles once the Red Hat transition was fully complete, but now he is the new President of IBM.  Nice!
  • This move of Whitehurst to Presidency demonstrates that the ideals of Red Hat are truely being integrated into IBM, like Ginni Rometty has said and proven many times before.
  • I am looking forward to what Krishna, who helped with the Red Hat acquisition, is going to bring to the table at IBM.
  • But I am going to miss Ginni Rometty’s self confidence, intelligence and matter of fact way of speaking.
  • And her pioneering spirit who reinvented IBM and led them to a new era of AI, quantum technologies, and cloud computing.
  • As a woman I have looked up to Ginni as a role model for many years, and under her leadership IBM’s commitment to diversity and inclusion has also advanced.
  • And in 2018, IBM received the prestigious Catalyst Award for advancing diversity and women’s initiatives.
  • There’s people saying IBM will merge into Red Hat because of this.
  • While that prospect sounds amazing for a Linux user such as myself, I don’t think that’s what’s happening.
  • IBM has a tradition of replacing its CEOs at the age of 60 or so. 
  • Every IBM CEO (minus the founder) has noped between the ages of 57 and 62.
  • It boosted IBM’s stock price by 4.5% last Thursday. 
  • IBM got in on the Cloud ™ late and it will be a small miracle if they get any significant tracktion. 


Material painting

  • I was gonna poke at it but then I read the first line of the how to build it on Linux
    • node Kromx/make -g opengl
    • Nope!
  • Start painting your 3D models with ArmorPaint, which is a stand-alone software designed for physically-based texture paint.
  • ArmorPaint is node based with fully procedural materials, and unlike many other options in this space, completely runs using the GPU, and is open source!
  • And viewport rendering with Vulkan is in the works.
  • ArmorPaint loads fast, works exceptionally well, imported and exported meshes easy and is only about 8 megs installed :-D
  • My favorite texture painting software is Blender and Maya, the later being very expensive and proprietary.
  • Also there are other well known PBR programs that are used in the industry, such as Substance Painter, ZBrush, Mari and Mudbox, but all are expensive and proprietary.
  • And yes, like Mfoxdogg says in chat, “this is taking more than a few design cues from Blender”
  • It’s designed to work with Blender, even including a keymap preset. 
  • ArmorPaint is available for 19.00€ EUR on itch.io or $19 at ArtStation, which is very inexpensive.
  • The funding model is straight out of the Ardour playbook.
  • If you want handy prebuilt binaries from the developer you have to pay a small fee.
  • The project is open source and you are welcome to build it yourself but keep in mind that you will be running code in active development. 
  • Reminds me of Substance Painter, one of the few (if only) Adobe apps available on Linux. 


Lightworks Beta 

  • Four of my favorite improvements to the new Lightworks Beta that are industry standard and I needed for my workflow:  
    • Images now import at the correct scale ratio rather than being scaled to the output format.
    • Added ability to drag an image into the sequence viewer or timeline.
    • Added ability to apply effects to selected timeline segments.
    • Also, there is a new right click ‘Speed’ menu item to easily make speed adjustments of videos.
  • Also, I like that the audio network and Pond5 royalty free audio video clips can be easily imported and searched.
  • Overall, I am really enjoying the more recent versions of Lightworks.  There is a much improved workflow that is inline with the Davinci’s and Premiere’s of the world, but at the same time has its own very unique and fast workflow. 
  • They’ve added decode support for HEVC/H.265 and for the most part that seems to work. 
    • Seeking is a bit slow. 
  • Added support for Ubuntu 19.04.
    • The one that is now EOL?
  • Had to complete a 3-step registration. 
  • Needed to install libcg. 
  • Can only export @720p using h.264 making the free version utterly useless for testing in 2020 where 2160p is the norm. 
    • Throw a watermark on that business during export and let me see how this product compares. 
  • That said, the available export is CPU dependent and I’m not going back to that nonsense. 
  • Nine years ago when EditShare planned the release of the open source version (after they finished code review) I was willing to give them all kinds of passes. 
  • It would have been a great addition to open-source NLE editors. 
  • That never happened, silence. 
  • So I’m comparing closed-source to closed-source \:D/ 
  • Apples to wrenches?
  • Next to Resolve Lightworks is a tinker-toy that hasn’t been relevant in the film industry for the last decade. 
  • And it costs more: $24.99 month, $174.99 year, $437.99 outright.
  • Save yourself $138, pick up Resolve, and learn some transferable skills. 


MS Openchain

  • Good on you Microsoft, who is following in the footsteps of the likes of Google, ARM, Qualcomm and SUSE who already have OpenChain conformance.
  • The OpenChain Project builds trust in open source by making open source license compliance simpler and more consistent.
  • The OpenChain Specification defines a core set of requirements every quality compliance program must satisfy. 
  • Openchain is open to all distributed ledger technology. Openchain is used by organizations who want to issue and manage digital assets in a secure, robust and scalable way.
  • Openchain is not “Blockchain”, but it is a close cousin of Blockchain that falls under the umbrella of Blockchain Technology.

Slice of Pi

Triangle Pi 

  • This is so exciting, and I am thoroughly looking forward to watching Vulkan development on the RasPi!
  • Shortly after GLES 3.1, Vulkan pops up.
  • Well, a triangle that’s technically being rendered in Vulkan.


Synth Pi 

  • Hadn’t read anything in Italian in a while.
  • That was a bit jarring.
  • And being able to do classic FM, sawtooth wave, squarewave and pulse wave modulation and manipulation on a Raspberry Pi!
  • Imagine the cost savings of a SynthBerry Pi!!!!  A classic synth can cost you thousands of dollars or more!
  • Artislab also has several other prototype Arduino based synths and sequencers as well, and sells their “sound card” boards for them, a capacitive board and a mixer, ranging from €15.00-€39.00.
