Lattice of Convenience

There is a lattice of convenience which runs my house. From ripping CDs and DVDs to Kodi, Arcade cabinet, and a shitphone army acting as media players and remote controls. These posts describe how to sysadmin my house.

RDPLauncher

TL;DR: Here's the Link:
RDPLauncher

I use RDP a lot and had some scripts to let me launch lots of RDP sessions without having to enter my random-generated passwords over and over. I wasn't happy with how I was handling those passwords so I've made it more secure using gpg and KeePassXC. Last night I made it compatible with Windows and MSTSC which will be uploaded here shortly once it's cleaned up a bit.

Basically I'll click a shortcut for whatever host, which runs my launcher. I get prompted for my GPG passphrase, which reads from an encrypted file containing my KeePassXC passphrase, which is then used to retrieve the user password for launching the RDP session.

Gpg-agent uses a cache-TTL to "hold the door open" for 10 minutes by default, so I can launch a bunch of sessions and only type my passphrase once.

Requirements:

- gpg client and running gpg-agent (gpg4win, etc) with a private key set up, etc.
- cygwin if you're running Windows
- KeePassXC (or some other key-store that has a command-line interface
to query the database. In the beginning I was just using the gpg file
with user/password pairs, so that works too)

The tool has a few neat features:

- If run from the command line with no arguments, it will prompt for user/pass/host/domain, good for one-off sessions to machines I won't log into much. That's great since I spend all my time in terminal windows and this stops me having to go back and forth to the mouse and keyboard while entering credentials.

- If launched with -b, it prompts you for information for a one-off connection, but will also build a new shortcut launcher from a template. So like for the first connection to a machine you know you're going to use a lot. (Linux/Mac only)

- Automatically tunnel sessions over ssh. This means I can launch RDP sessions on my Mac and they'll seamlessly proxy through my work laptop to the VPN.

For tunneling, I am taking an arbitrary range of 200 ports and incrementing them based on what's currently listening. If there's already a process listening on port 6201, then try 6202 etc until there's an open one. So I can easily open 20-30 ssh tunneled sessions each with its own ssh process which will close down when the RDP window closes. 200 is "probably overkill", which means it might just be barely enough in the real world.

The launcher shortcut mechanics are a bit different on my Linux and Mac machines so I split the -b script builder piece out based on OS. On Linux, I use KDE/Plasma, and so I generate these as KDE desktop files which look like this:

#!/usr/bin/env xdg-open
[Desktop Entry]
Comment[en_US]=
Comment=
Exec=/home/xrayspx/bin/rdplauncher.sh -h it-host.xrayspx.com -d xdomainx -u xrayspx
GenericName[en_US]=
GenericName=host.xrayspx.com
Icon=remmina
MimeType=
Name[en_US]=
Name=host.xrayspx.com
Path=
StartupNotify=true
Terminal=false
TerminalOptions=
Type=Application
X-DBUS-ServiceName=host.xrayspx.com
X-DBUS-StartupType=
X-KDE-SubstituteUID=false
X-KDE-Username=

On the Mac side, I use shell scripts with the extension .rdp (which conflicts with Microsoft's client, but I don't care since I never use their client anyway). Those just launch using Terminal, so it does pop a terminal for a fraction of a second, but I really don't have a problem with that. To get the Terminal window to close (and I do associate these files with Terminal.app specifically rather than iTerm2), open Terminal.app, go to the Terminal menu -> Settings -> Profiles (tab) -> "Basic" or whatever profile is your default -> Shell (tab). Choose what action to take when the shell exits. I have it set to "Close if the shell exited cleanly" and "ask before closing" set to "only if there are processes other than the login shell..."

The launcher for that looks like:

#! /bin/bash
rdplauncher.sh -h host.xrayspx.com -d xdomainx -u xrayspx &

I generate those from the KDE .desktop files with a command like this:

for host in $(ls | grep "\.desktop$" | awk -F ".desktop" '{print $1}'); do cmd=$(grep Exec $host.desktop | awk -F "xrayspx/bin/" '{print $2}'); echo "\!#/bin/zsh" >> $host.rdp; echo "$cmd &" >> $host.rdp; done

That creates .rdp files in the same directory as the .desktop files, so now they can be moved around, have chmod set, etc.

If I call it with AppleScript or Automator instead of a bash script as above, none of the password retrieval process works. I think it short circuits and sends the output back to the AppleScript rather than the bash script which ran the command. If I can get that working that would be ideal.

The mechanics on Windows are similar to the Mac method. a .bat file which launches the bash script via Cygwin:

C:\cygwin64\bin\mintty.exe -w hide -e /bin/bash -l -c '/home/user/bin/rdplauncher.sh -h host -u username -d domain'

On Windows at least the Cygwin window it creates is hidden from the user, so that's nice.

TV History Time

Music: 

Mojo Nixon & Jello Biafra - Nostalgia For an Age That Never Existed

So this is super interesting. You know, interesting to me anyway.

I'm compiling another week of vintage TV shows, this time from 1963. It's remarkable how easy it is to get the exact episode of many of these even compared to getting episodes from 1980's shows. I'm making a playlist for each night and mixing in 1963 commercials throughout, should be fun. But first, see if you can spot why this week's playlist may present a particular challenge:

As I started out on Sunday night (TVue is boldly not adhering to the TVGuide dictate that Saturday is the first day of the week), I found that while I could find the episode of whatever show I was looking for, the air date listed in IMDB was for like, several months in the future, in some cases as far as March 1964. What the balls IMDB. So it made it kind of tricky to pin down given episodes.

After the 3rd or so show with this happening, I kind of noticed a pattern. Sunday, November 24, 1963 just doesn't seem to exist. IMDB consistently showed "Nov. 17" and then the next episode aired was 'Dec. 1".

So seriously what the he... Oh. Right. Yikes.

My TVue, from the Boston Advertiser, is listing the TV schedule for the week after the Kennedy assassination. I am building playlists to recreate a week of TV which ... ... never existed.

For the record, this being the 24th, we chose Mister Ed, My Favorite Martian and The Judy Garland Show. I got all the right episodes on those, but I'd have liked to have seen the Ed Sullivan Show, but since that's live I imagine it was just canceled altogether. It was supposed to have a Stiller and Meara sketch, so I just picked one of those sketches from another Ed Sullivan. Growing up with Seinfeld it's just so easy to see "SERENITY NOW!", or "I've got a lot of problems with you people!". Genius.

As in my previous week of vintage TV, if I can't find a thing, I'll go for the nearest I can get. So for instance What's My Line on Sunday, Nov. 24 Instead I opted for the December 1 episode with Colonel Sanders. I don't know what was scheduled for that episode, or indeed if it was ever actually shot.

In addition to the JFK assassination horror, one thing that bums me out about this week is that I don't seem to be able to find any episodes of Grindl with Imogene Coca. I really want to see Aunt Edna, but young ('er, she was still in her '50s).

So here's to building a playlist for a TV Guide week that never happened. Obviously this is going to be oddly similar to 9/11/2001, and ... that's about it really. I can't really think of any other week where the machine of commerce would have simply ground to a halt entirely.

Lots of RDP

Music: 

Annie Lennox - Why?

Do you do lots of RDP? Like lots and lots? I do, and even with password management it's annoying. I tend to use generated passwords for all my normal user, Domain Admin user and obviously Administrator accounts. That means lots of workarounds to deal with those passwords while doing bulk RDP sessions.

A typical use case for me is to RDP to 20 machines at a time, run a thing, wait, and log out. I've always scripted this, but not always in strictly the safest way. Plaintext passwords stored in a script, or read off disk. The philosophy is "if someone can read this script, I've already lost the game anyway", but still it's ugly and sick, and so I fixed it. In my defense, the Red Team never did pop my laptop...

I already use gpg-agent to facilitate unpacking of log files. On my syslog servers I roll logs over hourly, gzip them and then gpg encrypt them to my key. Then I can download a bunch of them, run my logunpack script, enter my passphrase once and since gpg-agent caches that credential for a period of time, decrypt all my files in one go.

What I wanted here was basically a way to have keepassxc.cli "hold the door open" and cache the passphrase like gpg-agent does. So what I've done is to use gpg-agent itself for that purpose. I have a GPG encrypted file containing my KeePass-XC passphrase, and I open it using gpg-agent, so it can be reused until gpg-cache-ttl expires.

I've also always had slightly different copies of this script for use cases of "Fullscreen on my laptop" and "fullscreen on larger displays", so I have a switch here for "resolution" as well. "fs" for fullscreen or "fsbm" for "big monitors". Since I'll never go to my office again, that's pretty much never going to get used. The default for the $res value will remain 1280x960. Reasonable enough.

I also added prompts so that it'll ask for host, domain, user and password if you run the script with no prompts from a shell. So /that/ will be super useful to me when I have to do a one-off connection to some remote host but don't need a whole launcher for it. While I'm at it, I put in the -b switch so that you can have it generate a launcher based on that input. That saves me hand editing a template when I add a new RDP host.

I use Linux, but this should work with minimal-if-any changes on Mac and Windows/Cygwin, both of which can run xfreerdp and gpg-agent. I have a good automated ssh-tunneled RDP setup for my Mac, so I might try using that with this so I can use a 4k display for those "busy RDP days".

Being that I do run Linux, here's how I launch this. KDE desktop files like this:


xrayspx@dummyhost:~/rdps$ cat windowsmachine
#!/usr/bin/env xdg-open
[Desktop Entry]
Comment[en_US]=
Comment=
Exec=/home/xrayspx/bin/rdplauncher.sh -h windowsmachine -d domain -u xrayspx

So anyway, here's the thing: RDPLauncher

Rippin' DVDs

Music: 

Dana Carvey - Choppin' Broccoli

Today in Lattice of Convenience news, here's how to rip DVDs.

I barely understand the mencoder command that is the backbone of this thing, and there are many better ways to do lots of the stuff in this script, in fact I know several of those better ways, and looking at it fresh, I see some redundant stuff that cancels out other stuff. But it runs, and I use it, so here goes.

Ripping DVDs isn't fun, the disk labels are iffy at best, even within a single box set you might go from the Gold Standard "TV Show - S1D1" to "DVD_VIDEO" as a disk label. So it can get kind of ugly. To mitigate that I create an output folder based on the DVD disk label + a timestamp. If you get a run of disks with the same name, at least they're not overwriting each others files because the timestamp will shift. I currently have a dvdrip-output directory with the following DVDs in it:

...
DVD_VIDEO-090720202337
DVD_VIDEO-090820201025
DVD_VIDEO-090820201027
DVD_VIDEO-090820201142
I_LOVE_LUCY_S2_D1-090520202354
I_LOVE_LUCY_S2_D3-090620201047
LUCY_S1D1-090520201043
LUCY_S1D2-090520201043
LUCY_S1D3-090520201359
...

Those are all from the same box set. So that's 3 naming conventions from one series. To be fair I think that while it's the same company producing them they probably came as separate "season" boxes rather than one big set. Still. Come on. Jesus.

Another big gotcha I've hit, again mainly with TV series box sets, a single show might exist on the disk as many as THREE times. Once as a "standalone episode", once as "episode with commentary track" and once as part of a massive concatenated file of all the episodes on that disk. In the case of the commentary track, that audio seems to be separate, so the actual episode rips to exactly the same filesize, the commentary track seems not to be something I have access to, so you just get two identical files at the end.

So as you're ripping, that's going to triple the rip time.

The way I'm trying to fix that is to rip the first 30 seconds of every Title on the disk, then do a SHA sum on those ripped sample files. As a Title rips, when it's done I'll drop its clip checksum into a "rippedchecksums" file. The next TItle starts the first thing it does is check to see if its checksum has already been ripped. If it has, skip it. It seems to catch 100% of repeated Titles, and probably 70% of the "Big Concatenated File" cases will match the sum for Title 1. Saves a shitload of time.

In this case, Title 1 is a standalone episode, and Title 21 is the Big Concatenated File of all the episodes on the disk. Title 21 will be skipped. Since I get about 70 or 80 FPS on my Mac Pro, that probably saved 90 minutes of rip time or so with 3 hours of video on the disk:

At the end of it, I still end up with just a directory full of files labeled 1 through whatever.avi. I have to take a few seconds per file to get it to "TV Show - S01E01.avi". But from there FileBot can mass-rename them with episode titles.

So here's the full ugliness. You'll want to adjust all the paths. I should have made variables, but I don't care, I maybe have 3 or 4 ripping trays running at a time on various machines, so I don't mind just changing the paths for each host. Works on OSX and Linux, and probably Windows with Cygwin, but I don't care about Windows so I'm not going to test it.

Bouncing from Kodi to EmulationStation, and back

Music: 

Ninety-Nine And A Half (Won't Do) - Wilson PIckett

Update:

----
As pointed out on the RetroPie forum, just add the loop in autostart.sh, duh: I searched for a while before writing this thing and if I'd seen anyone mention that I'd have just done that instead.

while :
do
kodi
emulationstation
done

I also think it makes a more sensible default for RetroPie to implement. That's all I actually wanted at the start.

However...

Now I've added Features. I can hijack my loop and add one-off commands.

So now there's a Desktop button in my Kodi main menu that will touch a file to cause the loop to gracefully exit Kodi and send me to a desktop session. When I leave the desktop session, it takes me back to Kodi. So that's pretty goddamn convenient.

-----

Because if there's one thing I love, it's having to sysadmin my TV.

Like most reasonable people I use a Kodi mediacenter to run my TV. Lately this has been on a Raspberry Pi 4 running RetroPie. Generally people boot RetroPie into EmulationStation and use it as an emulator, such as on an arcade cabinet. I'm also one of those people.

But in this case I primarily use the TV to watch TV shows and movies, but also want to run console games, so I upgraded to a better RPi and migrated from LibreElec to RetroPie.

RetroPie lets you choose whether to boot into EmulationStation or Kodi, which is fine, and the idea is that if you quit Kodi, it loads ES so you can play games. That works fine. Once. The trouble is in going the other way. If you quit EmulationStation, you exit to a shell. If you run Kodi from within the Ports menu in EmulationStation, well, now you're running both ES and Kodi. This also changes the behavior the next time you quit Kodi to play a game. You end up back in the Ports menu with Kodi highlighted, because ES never quit.

So, that's what I fixed.

The way the RetroPie tool works is they create a script at /opt/retropie/configs/all/autostart.sh. If you have Kodi booting first, it will have two lines:

kodi-standalone
emulationstation.

That script gets run at login time for the pi user. Basically it runs Kodi, and autostart.sh is still running. When Kodi exits, it runs ES and autostart.sh exits. If you wanted to you could just put 1000 lines of:

kodi-standalone
emulationstation
kodi-standalone
emulationstation
kodi-standalone
...

However that's ugly, so I kind of daemon-fied it with a bash script of my own that I wanged together in like 10 minutes, and then I launch that through their autostart.sh. I didn't want to replace their script with mine because the RetroPie one could get regenerated with an upgrade or if I hit something in RetroPie-config. It's safer to have their script call mine.

So what I do is I start with whichever application is passed to me in the command line:

autolaunch.sh -f kodi

Then I start an infinite loop and, based on what application the script is called with, it will start the first application. When that app exits, I change the value of the variable so that the next time it loops, it runs the other one:


#! /bin/bash

while getopts f: name
do
  case $name in
    f) fval="$OPTARG";;
    ?) printf "Usage %s: [-f application to start] args\n" $0
    exit 2;;
  esac
done

while :
do
  if [ $fval = kodi ]
  then
    kodi-standalone
    fval="emulationstation"
  elif [ $fval = emulationstation ]
  then
     emulationstation
    fval="kodi"
  fi
done

Downsides and ToDo's:

Obvious downside is that this makes it difficult to get a shell at the console of the machine. However, I can count on one hand the number of times I've had to do that in the last 6 years or so of running my TV from a Raspberry Pi, so I really don't care.

A definite ToDo is to add some level of process control and general safety so I don't somehow end up running a bunch of instances of Kodi and ES. I did test with "Restart Emulationstation", so it would pick up new games, and it seemed to work as expected. It didn't launch another instance of Kodi or anything.

My main ToDo is to have the ability to use more launchers. Basically right now I have a "Games" menu item in my Kodi main menu, I hit it, it just runs the Kodi "Quit" command, which causes ES to start. Same thing in ES, though I'm just quitting it using the context menu at the moment.

I'd like to be able to add a "Desktop Session" button to quit Kodi or ES and launch a desktop with a browser for those very rare times I want a browser on my TV. This would also solve the "can't get a local shell" problem, at least mostly. I could add a "quit to shell" in this way obviously as well. I think the best way to do this is to stop the script as I exit Kodi and restart it with a new starting value, like -f startx. Kind of like if it were a real system daemon.

However I think in my case, since I'm not a very good programmer, I'm going to just bang this out with a file in /var/tmp or somewhere which carries the "Next Command", so rather than update $fval as I am now, I'd check that file and have it read in each loop to set fval. That would allow me to hijack it from outside the loop.

So I'm in Kodi, if I quit, it's going to set $fval to "emulationstation" and load ES. However, if I run a shell script, and /then/ quit or killall kodi-standalone, that shell script can populate /var/tmp/nextcommand or whatever with "startx".

Then, when Kodi quits, it sets $fval to ES, the next loop comes, but instead of just launching ES, we check to see if there's a value in nextcommand. If there is, set $fval to that and run it instead.

Then you'll start an X session, and when that quits, it should take me back to Kodi.

I seem to recall Kodi's internal tools are pretty good, and I can combine "run this external command" with "run this internal 'quit' command" and assign that to a menu "Action". Just need to remember where all that stuff is.

Music Video Sorting?

Music: 

Teddybears ft. Robyn - Cobra Style

Anyone have any Deep Thoughts about how videos should be categorized? If not, skip it, this is really that boring.

--

Let's say for arguments sake that I'm building a playlist of
videos from 120 minutes (Like say from this comprehensive list right
here.

I've already decided that any band that gets one of their songs on 120 Minutes one time gets all of their songs in this folder. Because I don't want to have 3 different places where I can find songs of one band. It gets unruly. The only exception to this is the "Arcade Pizza" folder. These are songs that ubiquitous on the radio when I was a kid, especially in arcades and pizzerias of the '80s and '90s. For that case I have /videos/Arcade Pizza, as well as /videos/120 Minutes/Arcade Pizza.

Question is, should I only put stuff that appeared on the actual show, or should I put bands that /should/ have been on 120 minutes, but weren't, because MTV could show neither the full name of the band nor the full name of the song involved?

Or what if they're too new, like this video philosophically belongs to 120 Minutes, but it's only a year and a half old:

I think they should go in, but I'm holding off. Teddybears would have been HEAVY ROTATION on 120 minutes if they'd existed then.

Should I kick Evan Dando out because he spoiled my Juliana? These are questions that require fucking answers.

I'm nearing 3000 music vids now, so these things are starting to become problems I have to think about. I need to nip this shit in the bud before I have 20,000 videos and no damn plan at all.

The Bonus Question is: Do I change the name of the Youtube video to fit a rational style, or leave it alone? For instance:

I Was A Teenage Zombie (2016) [heHh9EIlAbw].mp4

Should be renamed to:

The Fleshtones - I Was A Teenage Zombie (2016) [heHh9EIlAbw].mp4

The "[heHh9EIlAbw]" is the only actually important part of that filename anyway, since that's the video ID on Youtube, so it'll be youtube.com?v=heHh9EIlAbw. That is there for pattern matching, so I think that makes it OK to rename shit.

Right?

New Order - 5 8 6

Since posting about the week of 1983 TV Guide viewing, I've had questions from some people wondering about the storage and other hardware and software we use for our media library. It's really not very complicated to do, though I do have preferences and recommendations.

So here's what we've got.

Motivation:

Mainly I don't like the level of control streaming companies have. That they monitor everything we do, and that stuff comes and goes from services like Netflix and Amazon Prime on their timeline, not mine. I don't like the concept of paying for things like Spotify so that I can rent access to music I already own.

I realized like 15 years ago that while we often spent $200/$300 per week on CDs earlier in our marriage, Natalie and I were drifting away from actually listening to it much, because who wants to dig around for a CD to hear one song, then move to another CD. Ultimately, the same applies to movies, we have lots of DVDs, and I don't want to have to dig through booklets just to watch a couple of James Bond movies.

It's super easy to maintain, and we like being able to watch Saturday morning cartoons, "Nick-at-Nite" or throw on music videos while we play arcade games and eat pizza. Once up and running, it's all pretty much push-button access to all the media we like.

Media:

- 2000-2500 CDs (Maybe 200GB of music)

- Couple hundred movies, really probably not as many as most people.

- Lots of TV shows. Space-wise, this is where it adds up fast when you're ripping a box-set of 10 seasons of some show.

- Commercials, mainly from the '80s and '90s, but I'll grab anything fun that strikes us.

- Music videos. We have an overall collection of around 2000, and a subgroup of about 700 which represent "'80s arcade or pizza place" music. That's music that was just ubiquitous when we were growing up in the '80s and early '90s, and you heard it all the time whether you liked it or not. I've since come to appreciate these songs and bands in a way I didn't when I was a dickhead punk kid.

So all told, there's about a 5TB library of stuff, mainly TV shows, but also a decent music library that needs to get maintained and served.

Hardware:

- Ripping machines - Mainly, all I need is the maximum number of DVD trays I can get my hands on. There's nothing special here. My tools work on Mac or Linux so I can work wherever. We have one main Mac Pro that has 2x 8TB drives mirrored which hold the master copy of the media collection.

- NAS - Seagate GoFlex Home from like 10 years ago. I think I originally bought this with a 1TB drive, and have since upgraded it twice, which is kind of a massive pain. Now it's got an 8TB drive which has a copy of the media library from our main machine. I'll get into the pros and cons of this thing below.

- Raspberry Pi - I have a multi-use RaspberryPi which does various tasks to make things convenient and optimizing TV viewing. There are a handful of scripts which create random playlists every night for various categories of music videos, TV shows (Sitcoms, 'BritBox', 'Nick-at-Nite'), etc. It also runs mt-daapd, which I'll get into below.

- Amazon Fire Sticks - We have a couple of them. I'm not super impressed with their 8GB storage limit, but I'm definitely happy enough for the money they cost. They're cheap, around $20 now, and they do what they say on the box. Play video. I have side-loaded Kodi 17.x, but they seem not to quite have the resources for 18.x, though I'm really not sure why not. It's just slower.

- The Shitphone Army - I've got obsolete phones (Samsung Galaxy S4-ish) around the house and decent speakers set up so we can have music playing while doing the dishes for example.

Software:

- Kodi - I mentioned Kodi, which is just an excellent Free Software media library manager. Kodi gets /such/ a bad rap because of all the malware infected pirate boxes for sale, but you never see much from people who actually use it to manage a locally stored library of media they own. Can't recommend it enough. Get familiar with customizing menus in Kodi and making home-screen buttons linking directly to playlists. It's worth it and makes it look nice and easy to use.

- mt-daapd - I'm running out of patience with music streaming, though everything does work right now. MT-Daapd just basically serves up a library of music using the DAAP protocol, which used to be used by iTunes

- DAAP (Android app) - This could be great, but it seems to be completely un-maintained, and somewhat recently moved from being open source to closed, so unless I have an off-line copy of the source, there go my dreams of updating it. But it works well on the Shitphone Army and on the road so we can basically stream from anywhere. Other DAAP players for Android are pretty much all paid applications, and none of them seem to work better particularly than DAAP.

- Scripts A handful of poorly written scripts for ripping DVDs and maintenance of the library (below)

Recommendations:

Players - While the Fire Sticks work great, they're really very dependent on having constant access to Amazon. Were I installing mainly a Kodi machine, it would be much better to use a Raspberry Pi either with a direct-connected drive or mounting a network share. It's super easy to set up with ready-to-go disk images which boot straight into Kodi.

Playlists - Create lots of playlists. Playlists and randomizing things are two things that Kodi is terrible at, so I don't try to make it do it. These scripts run nightly on the Raspberry Pi and make .M3Us for us.

Filenames - Have a good naming convention. All my playlists are M3Us of just lists of files. That means that you don't get Kodi's metadata database with the pretty titles and descriptions, and so the files must be named descriptively enough that you can tell what episode you're looking at from the list of filenames. My template is "Name of the Show - S02E25 - Title of the Episode". Kodi's scrapers work well with that format and it makes it easy enough to fire up the Nick-at-Nite playlist and decide where to jump in.

At various times, I've considered parsing a copy of the Kodi database to suck out the metadata and add it in before the file location. In an M3U, that looks like this:

#EXTINF:185,Ian Dury & The Blockheads - There Ain't Half Been Some Clever Bastards
/mnt/eSata/filestore/CDs/Ian Dury & The Blockheads/Ian Dury And The Blockheads The Best Of Sex & Drugs & Rock & Roll/17 There Ain't Half Been Some Clever Bastards.mp3

It seems like having all that sqlite stuff happening would add a lot of overhead to generating playlists, and having well-named files saves me from having to worry about it, so I haven't bothered.

Storage - Though I use a "Home NAS" product that overall I've been pretty happy with, it does irritate me. Consumer market stuff is /so/ proprietary that it's quite hard to just get to the Linux system beneath and customize it the way you see fit. Specifically in the case of the GoFlex, "rooting" it even involved replacing Seagate's customized version of SSH with a vanilla one. Screw that up and you brick the device. I also run into network bottleneck issues with that thing. While you can enable jumbo frames, for instance, when syncing new content the CPU gets pegged, I believe I'm running out of network or disk buffer, which is kind of unacceptable in a NAS device.

Building it today, I'd just use a Raspberry Pi 3 with a USB drive enclosure. For the time being, my growth curve is still (barely) pacing along with the largest "reasonably priced" drives on the market. My ceiling is about $200 per drive when I do upgrades, because I am a very cheap man.

I have no opinion on consumer RAID arrays. I can only imagine consumer RAID based NASs come with all the shit I hate about the GoFlex. Yes, I'm biased against consumer grade garbage tech and that's probably not going to change. I'll have to buy one someday I'm sure, but for now it's all being kept simple.

Backups Keep backups. While I have multiple copies of everything, it does make me somewhat nervous that the only part of the media library currently being backed up off-site is the MP3 collection. That's got to change, and rsync is your friend. Ultimately I'll probably end up upgrading my home Internet from 20Mb/2Mb to something which will allow me to sync over a VPN tunnel to somewhere off-site (friend's house, work...).

Sample Scripts:

Here are some samples of the shitty bash scripts that run this whole nonsense. I know the better ways to write these, but the fastest possible way to hammer these out worked well enough and there's no way I'm going to bother going back and fixing them to be honest.

Rip CDs

I use an application called MAX on the Mac to rip CDs. I think its usefulness might be coming to an end, and I'm not sure what to do about that. It uses (used?) MusicBrainz database to automatically fingerprint and tag discs, but the last CD I ripped it seemed to have problems. You can run iTunes side by side with Max and drag the metadata over from there, so maybe that works well enough?

Anyway, I use that because I rip to both 320k CBR MP3 and FLAC. I have a shitload of stuff that really should be re-ripped since they're 128k and no FLAC, but I've so far been unmotivated to do so.

I wrote a bunch of stuff to move all the output files around and update iTunes libraries. Honestly I don't rip a whole lot of new music, which is a shame and which I should really fix.

Rip DVDs

DVD ripping is a lot more fragile than it should be. Good software like Handbrake are bullied into removing the ability to rip protected DVDs, and things are being pushed toward the commercial. I use mencoder in the script below.

DVD titles are sketchy at best, and as far as I know, you can't really fingerprint a DVD and scrape titles in the way you can with CDs. So I do what I can. I take whatever title the DVD presents and make an output directory based on that name plus a timestamp. That way if you're doing a whole box set and all the DVD titles are the same they're at least writing out to separate directories and not overwriting each other.

As far as file-naming, unfortuantely we don't live in the future yet and that's all down to manually renaming each output file. I use the information from TVDB, not IMDB, since that's the default library used by Kodi's scrapers. Sometimes the order of things is different between that and IMDB (production order vs airing order vs DVD order issues plague this whole enterprise).

#! /bin/bash

timestamp=`date +%m%d%Y%H%M`
pid="$$"
caffeinate -w $pid

id=$(drutil status |grep -m1 -o '/dev/disk[0-9]*')
if [ -z "$id" ]; then
echo "No Media Inserted"
else
name=`df | grep "$id" |grep -o /Volumes.* | awk -F "Volumes\/" '{print $2}' | sed 's/ /_/g'`

fi
name=`df | grep "$id" |grep -o /Volumes.* | awk -F "Volumes\/" '{print $2}' | sed 's/ /_/g'`
echo $name
dir="$name-$timestamp"
mkdir /Volumes/Filestore/dvdrip-output/$dir

echo $dir

for title in {1..100}
do
/Applications/mencoder dvd://$title -alang en -ovc lavc -lavcopts vcodec=mpeg4:vhq:vbitrate="1200" -vf scale -zoom -xy 640 -oac mp3lame -lameopts br=128 -o /Volumes/Filestore/dvdrip-output/$dir/$title.avi
done
chmod -R 775 /Volumes/Filestore/dvdrip-output/$dir

Playlist Script

The simplest Music Videos one below just looks at one directory of videos and one directory of TV commercials and randomizes all the content into an M3U. The more complicated ones have dozens of directories, and I'm sure I'm doing this array-building the wrong way. I'm sure I could have a text file with the un-escaped directory names I want and read that to build the array, either way, it really doesn't matter because if I want to add a TV series, I still have to edit a file, so this works fine. I've also thought about having a file in each directory like ".tags" that I search for terms in, like "comedy,nickatnite,british" and build the array from that, I dunno, sounds like work.

#! /bin/bash

array=`find ./ -type f;
find ../../Commercials -type f`

printf '%s\n' "${array[@]}" | sort -R | grep -v dvd_extras | grep -v "./$" | grep -v "\.m3u" | grep -v -i ds_store | grep -v ".nzb" | grep -v ".srt" > full-collection-random.m3u

- rsync the TV library. I have several of these, one for TV shows, one for movies, music videos, mp3s etc. It's just somewhat faster to only sync the thing I'm actually adding content to, rather than have to stat the entire library every time I rip a single DVD. The TV show sync tool also deals with the playlists, which are actually created on the NAS drive, so they have to be copied local before syncing or else they'll just get destroyed every day.

This checks to see if the NAS volume is mounted, if not it will mount it and re-run the script.

#! /bin/bash

mounted=`cat /Users/xrayspx/xrayspx-fs01/.touchfile`

if [ "$mounted" == "1" ]
then

cp ~/xrayspx-fs01/Common/TV\ Shows/1\ -\ Playlists/* /Volumes/Filestore/Common/TV\ Shows/1\ -\ Playlists/

rsync --progress -a --delete /Volumes/Filestore/Common/TV\ Shows/ ~/xrayspx-fs01/Common/TV\ Shows/

~/bin/umounter.sh
exit 1
else
mount -t smbfs //192.168.0.2/filestore ~/xrayspx-fs01/
~/bin/synctv
fi
