Series 1 Episode 9 – A variey of topics discussed this fortnight, including Intel AMT vulnerability, Humble Bundle offerings, spreading the good word of Linux, more Midnight Commander , Command Line Linux tools and another epic Irish saying, have a listen.
00:24 Intro, only some weather and nail gazing. Mark is calling from the tech hub of Coolick, Killarney. Pick up the number of blips due to wireless tech and you could win a NICE biscuit.
01:52 Mark’s been trying to get everything working (successfully) in his mobile studio and has also come to the conclusion that he needs to spend some time tweaking his KDE Neon set up.
02:52 Wayne’s installed Ubuntu Mate on his CEO’s Toshiba Satellite and a HP Mini 210. Wayne’ll report back on this linux noob’s experiences.
12:45 Wayne extolls the virtues of Gumtree as compared to other trading sites.

14:45 Wayne’s extolling the virtues of Gumtree because he was able to pick up a roll of Kortex CAT5e for £15! He’s hoping to do some outdoor Raspberry Pi CCTV IP stuff with it.
19:12 Wayne’s made a template in Ardour for the podcast recordings!
20:09 Wayne talks about his servers’ setups, isolation, port setup and nginx reverse proxy servers.
24:46 Wayne talks about the Intel AMT vulnerability. Mark accepts the fact that security vulnerabilities will always exist because creators create and crackers crack. The intel software checker is not available for linux yet but apparently is on the way
NOTE: for those concerned an AMT status checker is available for linux, courtesy of Matthew Garrett.
31:58 Mark mentions the Humble Indie Bundle 18 and the Humble Book Bundle Make:Essentials.
35:38 Under the Hood:
Mark talks about the following:
apropos [insert keyword to search for], a command to search man pages for the provided keyword and to display the results on screen.
example being:
apropos audio | grep pulse
He mentions the following:
find
type
which
locate
slocate
ls
man apropos
pavucontrol
41:52 Wayne has a midnight commander (mc) tips section:
Ctrl + Space – on any directory shows the directory size opposite
Ctrl + – Opens up the bookmarks window, good for speedy access to directories
Alt + , – switch mc’s layout from left-right to top-bottom. Useful for operating on files with long names.
Here’s the link where Wayne is getting (some of) his tips from.
Dog’s eager for a walk help wind up this episode, but not before Wayne presents the Irish Saying of the fortnight: “Nil aon tinteán mar do thinteán féin” – There’s no fireplace like your own fireplace (ie. there’s no place like home).

Series 1 Episode 8 – A variey of topics discussed this fortnight, including OpenZFS intro from Wayne, Mark is trying out Linux Mint , Command Line Linux tools and another epic Irish saying, have a listen.
00:24 Intro, changing weather! Wayne and Mark talk about false starts.
01:26 Mark’s not been up to a whole lot apart from a course, he’s still trying out Linux Mint but is still not sure if he wants to switch, while also mulling over switching out Unity for KDE. He’s also set up another VM and put squid on it, as well as wishing he kept better notes.
04:01 Wayne has been fixing full boot partitions on VMs. Extending boot partitions isn’t the way to go, here’s how he fixed it:
uname -r (to find the currently installed kernel)
dpkg –list ‘linux-image*’ | grep ^ii (list all installed kernels)
sudo apt-get remove linux-image-[insert kernel version you want to remove] (remove unused kernel version)
sudo apt-get autoremove
sudo update-grub
Taken from What is the safest way to clean up the boot partition
09:24 Wayne goes on to tell us about an article he read on omgubuntu relating how Firefox multiprocess is disabled on Ubuntu by default. This is because the Ubuntu modifications add-on that comes pre-bundled with the browser is not yet compatible with it. Enabling This Makes Firefox More Responsive On Ubuntu
13:03 Are we ready for more of what has Wayne been doing? Wayne rattles through some apt commands and tells us about the advantages of using apt over apt-get. Here are the commands:
sudo apt install (adds progress bar)
apt depends firefox (list all dependencies for firefox)
sudo apt remove
sudo apt purge (removes config files as well as program files)
sudo apt autoremove (remove old unused kernels – SSD space saving)
apt show firefox (show information about the application)
apt search mc (search for all instances of mc)
apt –help (view all apt commands)
17:02 Mark talks about the Zero Phone, a $50 smartphone made using the pi zero and arduino, and how it will be available soon on crowdsupply.
21:54 Wayne tells us about his journey with ZFS. ZFS learning links can be found as follows:
Ubuntu Wiki on ZFS
Open-ZFS Bootcamp
ZFS 101
Becoming a ZFS Ninja Part 1
a friendly guide for building ZFS based SAN/NAS solutions
36:26 The conversation moves from filesystems onto backups. Wayne’s got a good onsite backup regime in place, Mark blames his “office tidy up” for the lack of his.
40:17 Wayne’s concerned he didn’t do ZFS the justice it deserves and recommends we watch the youtube video links, while Mark reckons he’ll definitely check them out. We’ll find out next week… Meanwhile, thank you Sun for ZFS!
43:38 Under the Hood – Mark kicks off under the hood with screenfetch, a Bash screenshot information tool. The coolest thing about screenfetch is the ascii art logo (and all the other useful information it provides).
45:34 In terms of “serious command line stuff”, check this out (for a silly example):
(cd /tmp && ls > list.txt && mv list.txt ~)
48:05 Wayne tells us about various forms of diff and vimdiff:
diff is useful for finding the difference between config and text files (i.e between config.txt and config.orig) e.g.:
diff config.txt config.orig
diff -u adds modification dates and times, unified output, e.g.:
diff -u config config.orig
vimdiff shows both files opened in vim side by side with differences highlighted – VERY COOL!
vimdiff config config.orig
e.g. seq 1 7 f1.txt && seq 1 9 f2.txt && vimdiff f1.txt f2.txt
49:40 Mark is so happy that these podcasts are made!
50:27 Mark wants to briefly mention the Humble Very Positive Bundle before the Irish saying.
51:49 Have we used Conas atá tú yet? Nílim ró olc in aon chor – Im not too bad at all

Series 1 Episode 7 – A variey of topics discussed this fortnight, including various distros from Mark, more ssh tips from Wayne, Raspberry Pi, Command Line Linux tools, have a listen.
00:24 Intro, more sunny weather, Wayne and Mark talk about the relativity of time.
01:43 Mark’s been tidying his office, bought an Asus 24″ Gaming monitor to complete his dual monitor setup and has been trying out different distros:
Open Suse Leap 42.2, a nice responsive desktop, but encountered dependancy problems once packman repositories were enabled.
Netrunner, a run everything out of the box using KDE and Debian experience, but found to be slow and unpleasant.
Downloaded Zephyr but didn’t do anything with it. Please note that as of 19/04/2017, Zephyr has been discontinued and is now Crowz.
Deepin, a Debian unstable based distro with a really nice desktop experience based on a dock and hot corners / sides.
Linux Mint, a fantastic out of the box experience where everything works nicely. Mark’s concerns around Mint’s security strategy make him wonder if it is a good idea to use it as a daily driver.
06:48 This leads into a discussion around Ubuntu updates.
09:00 Mark continues his gripe against Gnome 3 and mentions the OMG Ubuntu article petitioning Mark Shuttleworth to make Plasma Ubuntu’s Next Desktop. He plans to sign it.
10:08 Mark goes on to mention the TuxDigital video on Why Ubuntu 18.04 Should Use KDE Plasma Instead of GNOME while Wayne shockingly admits he’s not a KDE fan because he’s into light DEs (eg. MATE) and the terminal.
13:07 Wayne suggests we should both try Gnome 3 in a VM, then realises that you have to install on hardware to get a real feel. Mark says that’s what he did with KDE Neon and tells us that Dolphin is the best file manager bar none.
14:41 Mark mentions TuxDigital is a channel he hadn’t heard of before and intends to spend more time there. Wayne’s looking forward to that!
15:17 Wayne describes the wonderful world of ssh and the authentication errors he has to put up with when setting up systems. His way around it is to type the following:
ssh -o PubkeyAthentication=no pi@[insert ip address of pi]
19:03 Wayne goes on to say that he’s continuing his messing around with raspberry pi, leds, buttons and pull down resistors and gives a shout out to the CamJam Edukit worksheets.
19:45 Wayne talks about ssh, scp and Gigolo. To recursively copy directories with scp, use the following command:
scp -r user@your.server.example.com:/path/to/foo /home/user/Desktop/
21:56 Wayne talks about his experience of upgrading his Samsung Galaxy S3 from cyanogen mod to LineageOS. It wasn’t good.
27:10 Mark tells us his ubuntu phone was ideal for him and he wonders what to do with it and his BQ M10 tablet. For now he’ll just wait and see what progress yunit and the UBports guys make. This leads onto a discussion on the benefits of open hardware and firmware and Mark calling for more movies like the Fast and Furious 8 to create awareness around poorly implemented proprietary firmware, governments legislating against same and a disbandment of the WTO!

33:48 Wayne talks about something that happened a few months ago, FOSSDEM and the videos of the presentations. Mark mentions a keynote given by Aaron Siego back in 2015 at OSC in which he talks about the importance of making great free software.
36:32 This turns the conversation around to how software developers get paid making free software. Elementary OS’ App center is mentioned as a method for getting paid, and Mark points out that most kernel developers are professional software developers in paid employment. Mark also tells us he is an associate member of the FSF, donates to Blender, is a lapsed supporter of KDE and uses Kolabnow as his email provider. He believes the money is in the services around the software rather than the software itself. Food for thought.
42:03 Under the Hood – Wayne mentions the following:
Ctrl+U – to delete from the position of the cursor to the beginning of the line.
Ctrl+R – Recursive search, to clear the result from Ctrl+R use Ctrl+G
Mark tells us about a really cool command that he’s forgotten but has something to do with ps -ea |grep [app that’s causing problems] to find the pid and kill [pid]. His notebook is buried somewhere in the office.
Use id to show the active user id and last to show the last logins on the system
Mark mentions who and Wayne trumps him with w. w tells Mark he’s idling…

28:56 Under the Hood: Wayne starts the Under the Hood section while Mark scrambles to find something suitable. Alt-space, t to keep the current window on top. Mark can’t seem to get it to work in Unity, though he figures it out after the podcast. YMMV!
Mark suggests running gui programs from the terminal for troubleshooting purposes.
Wayne and Mark talk about ls type commands. lsblk, lspci -tv, lsusb -tv, lshw, lshw -c disk, lshw -short, lshw -sanitized all get mentioned, while Mark asks what is the dmesg option to show the time in a more readable format (dmesg -H).
Wayne tells us that inserting a space before a command prevents that command from being recorded in your history. This news wows and concerns Mark, so much so that he’s interested in finding out more.
