From “Obi-Tom Kenobi”:

I’m not one to write into a show that I listen to & I think that’s a problem with most Podcast listeners, We take advantage of the luxury of free content of learning and entertainment. So I’m asking my fellow listeners to take just a couple minutes out of their day to go to the contact link of the shows that they enjoy listening to and let the hosts know that they are appreciated and are doing something of worth to you. As for your show I don’t have a local LUG that I attend so it’s nice to feel like a part of yours. Out of all of the Pods I listen to I think yours has the perfect amount of diversity in it’s hosts, The knowledge and experience that each of you bring is priceless. I appreciate all that you all contribute and hope to some day find the time to join in on mumble.

Love & Respect

Very thorough feedback email from Jonas Rullo responding to 5150’s escapades with Octopi and Slic3r. Highlights:
Had trouble with 3D slicer programs, too

Seems to be a fan of Cura (actually the backend slicer to Octopi, though not all features are exposed)

But ultimately went with Slic3r after difficulties installing

Doesn’t recommend slicing directly with Octopi… advises slicing on the desktop and shipping the resulting gcode to Octopi (good network integration)

Raspberry Pi 2 is fast enough for Octopi. Probably not the Zero, though.

Recommends using a bit of a glue stick pre-applied on the bed since it isn’t heated. Also blue painter’s tape is worth trying

Followup:  5150 tried installing Slic3r and Cura on the Odroid U2, but they weren’t in the 14.04 repo (surprise).  He thinks the path of least resistance may be to put Octopi on the RPi 3 he has in hand and buy another for the Alexa/Mycroft/etc project.

REGLUE still needs help.  This year’s fund raiser was very disappointing. Partial review of Fedora 25 workstation install.  Create logical partitions using Gparted?  My Magigoo came in the mail today, also picked up blue tape.  Also got blue tape.  Got the ingredients for home made Sugaroo earlier this week, but procrastinated on repairing headphones, so my can is still hanging loose.

New Raspberry Pi Zero W, now with WiFi and Bluetooth.  New (to me at least) ODroid RPi Zero clone, ODroid W.
My 101 Hero 3D printer arrived, from reviews I don’t expect much. I currently have a ODroid U2 connected to printer.  The popular slicer software doesn’t seem to be in the 14.04 LTS repos.  Ran into a snag compiling Slic3r.  Also having trouble completing a distro upgrade.  Might be easier to get another RPi 3 and installing OctoPi

RetroPie calls for help (legal trademark issue):

(follow-up on this… they issued a follow-up thank-you on their blog. I don’t think that means the matter is settled or that they’ve gotten the help they need, so if you know someone, it’s probably still worth it to reach out)

Transmission-CLI: To download “Endless Linux” which I heard mentioned on Late Night Linux.   Installing “transmission-cli” on my server, (depending on distro, package may be either “transmission-cli” or “transmission-daemon”).  To enable web interface, “transmission-daemon -a 127.0.0.*,192.168.x.*” or edit ~/.config/transmission-daemon/settings.json
rpcwhitelist“: “127.0.0.*,192.168.x.*”,  
Note trailing comma is a file delimiter,   ^^ not my punctuation
rpcwhitelist-enabled”: true,
Also “download-dir“: “~/YourDownloadFolder“, && pick your own download dir

After settings change, kill the daemon with “sudo killall transmission-daemon” and restart with “transmission-daemon

Access a very Transmission graphical like interface at “serverIP:9091/transmission/web/”   The trailing “/” is important, you will get an error w/o it.

2 easy cli ways to record an audio stream

mplayer -dumpstream -dumpfile (location and name of dumpfile) (url of stream)

curl –output (location of dump file) (url for stream)
(note: “Redirect Target IP”, in both cases this is “From”), and substitute port used by Transmission, 51413, for the one in the article).  I’ve used RTorrent before to download torrents to a server with no GUI.  Luckily, RTorrent doesn’t seem to be available in the Arch repos, so I looked for an alternative.

I also made limited progress on installing Wallabag (a Pocket like utility for archiving links) on the same RPi that runs Nagios.  I’ll report more when I’m finished or at least make real progress.

I been catching up on Bad Voltage and just discovered Bryan Lunduke left at the end of the year so he could host “The Lunduke Hour” on Youtube.
