INTRODUCTION

Welcome to mintCast Episode 305.

This is Leo and with me this week are Bo, Joe, Tony Hughes, and Moss. We’re recording live on Sunday 24 th March 2019.

First up, in our wanderings, we’ll hear about upgraded kernels and Disco Dingo, Joe has two new tablets and needs ideas, Moss has done a RAM upgrade and tried out a few more distros, and Tony Hughes has been hard at work taking us into the past.

Then, we have news about SUSE independence, some articles about gaming, with and without android, and some updates to our Audacity workflow.

We hit our Innards which covers podcast production.

And finally, we cover listener feedback.

BI-WEEKLY WANDERINGS:

Leo Upgraded to Kernel 4.18. Waiting on 5.0 on Mint after Disco Dingo drops. The upgrade to the new kernel “fixed” my trackpad issues mostly . After a suspend, trackpad will get a slight bit of gesture input lag, so I still have to use the grub fix. Test driving 19.04 on my desktop.



Joe Re-installed LM on my garage mini pc to correct ssh issues and audio issues A work associate gave me 2 Fujitsu ST5000 tablets: Pentium M processor 1.1ghz and 2gb of ram but an awesome screen at 1024 x 768 Won’t do youtube very well or Plex but will do sshfs playback for 720p files X2go works great X11 forwarding is very hit or miss Peppermint, MX, Lubuntu. Required forcepae in initial boot up Lubuntu Initial login screen is dark but typed in password and got in Steam Installed on 3 OS’s but would not open in any Did get it to x11 forward from one machine and got the store loaded Tried to stream from another machine and failed Need Ideas for projects Probably going to use it as an Resilio SYNC node to help get away from dropbox May also use it as an intercom. Need to research some software.



Moss I got the 4 Gb RAM stick. Installed it. Had to reseat it. It went in the slot behind the door. Runs great, have not noticed a difference but I might when I get enough windows open… I installed Solus OS 4 on the formerly-MX partition (couldn’t get Grub Customizer [it was pointed out during the show by MintSpider on IRC that Solus has Grub Customizer available]) followed by installing MX on the OM4 partition (could get Grub Customizer). Then I ran Grub Customizer… and it refused to save, citing an error in line 191 of the file. Then I noticed that I did not have ANY internet connection in MX, despite the fact that I am wired via Ethernet, and that, with systemd, there was no functioning Network helper file. I am removing MX from my personal Recommended Distros list. I tried going back to KDE neon, with which I had zero problems with in 16.04 but had difficulties multiply as 18.04 updated. So. KDE neon would not load a desktop. Lubuntu loaded sorta, went to black screen, I could not advance further in the installation. I tried Ubuntu Budgie. Then I noticed that left me with two installations of Budgie, although they look different in Solus and Ubuntu Budgie, and so I loaded Kubuntu 18.10. Nothing major different… except that installing .deb files using gDebi winds up opening QApt, which does not complete the gDebi installation in the usual way. I’m considering hopping again, as I have managed to get Mageia 7 Beta 2 to run as a live distro and I’d be interested to note the differences between it and OpenMandriva 4 Beta. But not today. Fun note: Mageia’s live stick, when inserted, actually shows the Mageia logo on your desktop.



Tony H Creating archive folders of the audio on archive.org up to and including the special interviews for episode 300. A couple of people in the Telegram channel were having difficulty finding some of the episodes, I’ve also created a Blog post on mintCast.org with links to the folders. Upgrading the Dell E7250 to 16Gig Ram, managed to pick up 2 DDR3 8Gig modules £48 / $64 approx.



THE NEWS:

LINUX INNARDS:

Show Preparation

Planning – LEO

We use Discord to discuss show topics during the week. We aggregate feedback from all social media and email (discord, Telegram, MeWe, facebook, reddit, etc) and put that in the show notes

mintCast hosts meet every Saturday to discuss show plans on Mumble.

Google Doc is shared amongst all the hosts to place links and show notes throughout the two weeks.

Show production

Hardware

Tony H – Depending on my location or just where in the house I want to record from I’m either on my HP Elite 8300 Tower Intel Core™ i7-3770 [Quad] with 24 Gig Ram, I use the USB sound card to connect my Headset with integrated mic to this as I do when using my Toshiba Z30 i5 with 16Gb Ram, that I use as my mobile studio.

USB 7.1 channel sound card with a headset / microphone combo plugged into it.

Joe – MSI GE72-6qd 2.6GHz Intel Core i7-6700HQ laptop with a samson meteor microphone sometimes the snowball and a turtle beach headset earforce z2.

Bo – Xenyx 1622fx mixer, MXL 990 and MXL BCD-1

Leo – Thinkpad T450s (i5-5300U, 20GB RAM, WiFi), Linux Mint 19.1 Cinnamon (HWE Kernel 4.18), Blue Yeti, Bose SoundSport BT earbuds, considering Over-the-Ears

Moss – Lenovo ThinkPad T430 (i5-3320, 8 Gb RAM, Ethernet), LinuxMint 19.1 MATE, Blue Yeti, phone headset for headphones

Software

The show host all connect using the HPR Mumble server and we record the show via Mumble as a backup, in .flac, and recording the individual channels.

Audacity recording

Post Production

Tony H – Editing the audio

We all record locally using Audacity and at the end of the show we each export to a full quality .flac file. The show is then mixed in Audacity using the following process. Import the separate audio tracks and line them up using the markers we create before starting to record. Depending on volumes compress each file using a threshold of -30db, Noise Floor -50db and ratio of 3:1 and tick the box for ‘make up gain’ (this is a lot better since we introduced a mic mute key so our mic’s are only open when we are talking. Then we process each track with noise reduction using the 20-30 seconds of silence we create at the beginning to get a background noise threshold, then using 12db noise reduction, sensitivity of 6 and frequency smoothing of 3, we apply this to each track. We then check each track for any sound anomalies, that may not have been removed by noise reduction, and where possible remove. During this phase we also sometimes remove audio where we have spoken over one another, as long as it does not affect the context of what is being said. Once the tracks are satisfactory, we mix down the audio to one track and then add in any transition music not included during the show. We then run truncate silence to remove large gaps in the audio using Level -35db, duration 0.5s, truncate to 0.5s Finally we export the track as full quality mono .flac, mp3 (96kbps) and .ogg (quality 6)



Bo – Streaming

Our icecast is provided by Kwisher

OBS streams audio and video. Doesn’t require Jack Doesn’t stream to icecast We use nginx to convert our rtmp stream to an icecast stream

IDJC streams audio only Requires Jack Streams to icecast
