The Binary Times podcast, back with Mark

00:24 Series 4 Episode 4 starts with Wayne regaling us from a wet and windy Bristol, his spirits have lifted as the wind blows through his hair and the rain saturates him from head to toe. Mark is concerned that Wayne is experiencing that amount of weather while recording in his house though Wayne assures us that he is doing an outside broadcast. Mark goes on to tell us that the rain has returned to Kilkishen. The guys go on to discuss their differences in opinion on the weather.

02:04 Wayne asks Mark what he has been doing for the last while, and Mark tells us that the Kilkishen Coding Club took place with two families turning up despite the Clare / Galway Hurling match taking place at the same time. Everyone there had a good time coding in Scratch and some web design. Mark thanks the Kilkishen Parent's Association for kindly renting the cultural centre for the time to allow the event to take place.

12:36 Mark's other Linuxy news is related to setting up laptops and servers for the Kilkishen Coding Club, and he tells us how he found Ubuntu Server 18.04 too different from 16.04 to allow him to be productive quickly so he reverted to using 16.04. This leads to a discussion around the differences between Ubuntu server 16.04 and 18.04.

19:51 Wayne tells us what he's been up to. He finally started to work on his X220 Thinkpad laptop. He's installed Kubuntu 18.04 on it and is trying to take on the "K" suite of software. This provokes a discussion around embracing change and differences in desktop environments. Wayne tells us he really likes Kubuntu though it's not on his main machine and that Ubuntu MATE is still his favourite.

29:17 Wayne tells us a story about change and upgrades. He recently upgraded a kernel from 4.4 to 4.15 and hit a problem with wireless drivers. He found his solultion in the last post to a thread he found on the Ubuntu Forums.

30:43 Wayne decides to change topic completely and talk about his Cisco CCNA and his recent purchase of a microtik router and Microtik's RouterOS. This leads him around to talking about GNS3, a Graphical Network Simulator that does what it says on the tin. The guys recommend GNS3 as something to have a bit of fun with.

39:40 Mark talks about some listener feedback. Tom wrote in to suggest a linuxbabe article on how to install skype. This lead Mark to think about doing a segment on installing "essential" proprietary applications. In the meantime, Martin Wimpress wrote a blog post on detailing how to get productive on the Linux desktop with 7 essential snap apps. Mark goes on to tell us about the apps and how to snap install them.

45:20 Some more listener feedback, and this one is from Old Nerd on our Telegram group, detailing 4 simple steps to clean your Ubuntu System. This leads nicely into Under the Hood.

46:11 Under the Hood - Mark's under the hood is cleaning your apt cache. You do this by first checking the size, and you do that by typing:

du -sh /var/cache/apt/archives

If it is large, you can clean it out by typing the following:

sudo apt-get clean

47:38 Wayne talks about the ip route 2 suite of commands.

ip route - show the ip routing table

ip ad - show the ip address assigned to interfaces

ip ad sh eth0 - show the ip address assigned to ethernet0

sudo ip link set eth0 down - take down eth0

sudo ip link set eth0 up - bring back up eth0

50:40 Wayne thanks all our patrons and donors, most recently Squid from the Open Source Community on Steam

51:25 Irish Saying of the podcast - "Tá sé anna fluich", or it is very wet.

Thanks for listening, we hope you enjoyed the podcast as much as we did making it!

  1. Use raspi-config to enable the serial port (or add enable_uart=1 to config.txt) and reboot.
  2. sudo apt-get install screen
  3. Connect the three wires of the RS232 adaptor to pins 6, 8 and 10 of the Pi's header, and plug the USB plug into a free port on the Pi.

Mark and Wayne, kicking off Series 4

00:25 Wayne welcomes us to Series 4, yes that's right, Series 4! Whiskey Blue Skies predominate the weather report, with streams of weather producing highs at the height of Summer to help the guys reach new heights!

02:20 Mark announces the new collaboration between the Open-Source Community on Steam and the Binary Times. Wayne welcomes all the new Open-Source Community listeners to the podcast and also warns new listeners of possible down time

04:04 Mark tells us of the ups and downs he's had in his journey to create the perfect Binary Times t-shirt. He recently contacted Hello Tux, a family business that believes in promoting free and open source software, asking them if they would be willing to create a t-shirt for the Binary Times. They enthusiastically agreed and went about creating clothing based on Mark's designs. Mark received the first of the t-shirts, a black and a white t-shirt and a red carry bag earlier in the week, and is well impressed at the quality.

Hello Tux have also gratiously agreed to provide a t-shirt, which can be shipped internationally, as a competition prize. Mark gives out the competition question in the podcast, make sure to email with your answer before the 7th July 2018 to be in with a chance to win!

Thanks once again to Hello Tux for their generosity, open spirit, and promotion of free and open source software communities.

11:33 Wayne tells us about his last two weeks of linux admin bits and pieces. This includes updating his routers (the cause of some of the down time on the web site recently) and looking into his back up situation at home. LVM didn't work out for him as a simple home back up system, so he went with 2x2TB drives and rsync. He wonders if he's missing something with LVM and asks for any feedback. Mark speaks about his own back up home server back up regime in the informative way that Mark does. The guys chat about the pros and cons of zfs.

27:32 Wayne tells us about how he upgraded his partners SSDs and changing UUIDs.

29:38 Mark talks about the proposed European Copyright Directive and how it has moved one step closer to destroying the internet. Mark pleas with the listeners to SAVE YOUR INTERNET! by contacting their MEPs before the vote in July. Wayne tells us of some recent problems with content filtering. The conversation continues onto the GDPR and other implications of Copyright Directive.

41:53 Wayne brings back the conversation to Linux with a chat about Manjaro. He got the broadcom wifi working on an old Dell laptop by doing the folowing:

Go into the Hardware Configuration in the Manjaro Settings Manager, right click on BCM4311 adaptor and choose 'Remove', then open a terminal and type:

sudo modprobe b43

To make this solution permanent Wayne followed the guide in Ask Ubuntu to set up a systemd script. He also had to install an extra program called yaourt to install freerdp for Remmina, as shown following:

sudo pacman-mirrors -g

sudo pacman -Syyu

sudo pacman -S yaourt

Wayne knows he's put more time into these laptops than they deserve but he likes to keep old hardware alive and likes Manjaro.

47:29 Mark mentions Chakra Linux as another arch like distribution and tells us that Chakra had a large upgrade to a number of important packages including linux, graphics, audio and the like. Mark commends Chakra Linux and is glad to see it thriving.

49:05 Wayne talks about Copperhead OS and the recent problems the project has been having. He thinks he'll change to Lineage.

51:15 Mark drags out the podcast by talking about Will Cookes blog post on a first look at Ubuntu desktop metrics.

53:37 Wayne drags out the podcast a little more by having a discussion on the latest cyber-security bundle from the Humble Bundle. Mark is initially skeptical but seems convinced of the value of the bundle by the end of their chat.

57:17 Under the Hood - Mark tells us that you can login to snap using your Ubuntu single sign on account and that will provide you with the authorization you need to install / refresh etc. snaps without using sudo. More info can be found on the advanced snap tutorial.

1:01:45 Wayne's Under the Hood is certbot delete to delete old certificates from his Lets Encrypt directory.

1:03:03 Irish Saying of the Podcast: 'Beidh me Arais' or I'll be back. Mark comes back with 'Beidh biseach ort go luath' or you'll be better soon.

We hope you enjoyed the show as much as we did making it!
