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.

Kodi Machine Screensaver Notes

Music: 

Veruca Salt - Born Entertainer

I've just spent too long messing with a small PC to replace my Raspberry Pi Kodi machine. Problem was that the system would blank the screen after 10 minutes and there's too much stuff to test, and each test takes 10 minutes. Make a change, reboot, wait 10 minutes, make another change, and so on.

The problem was the Xorg default screen blanking, and it was fixed by creating /etc/X11/xorg.conf, with only the following config in it:

Section "ServerFlags"
Option "IgnoreABI" "True"
Option "BlankTime" "0"
Option "StandbyTime" "0"
Option "SuspendTime" "0"
Option "OffTime" "0"
EndSection

I had previously tried a bunch of stuff with setterm and enabling rc.local to run from Systemd, all to no avail, so I wanted to document this one for the next time.

Mac Classic Pt. 2 - This is Fine

Music: 

Pailhead - I Will Refuse

Note: I say "We" a lot. Natalie has been doing at least as much of this work as me. She has a whole method that she likes for the tantalum caps so she pretty much installed all of those. She even discharged the CRT. We learned later that the Classic seems to bleed the CRT automatically which is nice. I'm still sticking a screwdriver back there every time though just to make sure.

Good and bad news on the Mac Classic front.

If you read in part one, we over-paid a princely sum for a Mac which "Works as intended", but which should really have been "For parts or repair" for 1/3 what we paid.

So I'm personally beholden to make this fucker run regardless of personal cost in blood or treasure at this point.

"Rookies do very tidy job and rightfully feel pleased"

We recapped the motherboard on the Mac Classic. We got a heat gun, generous with the tape all around to make sure we didn't mess up any other components, and quickly and easily got the old parts off, we cleaned the pads up with solder wick, tinned them with new solder and put in the replacement tantalum caps, applying a bit of flux and cleaning regularly along the way. No damaged pads, everything went extremely smoothly regardless of which of us held the iron. Natalie really did most of the installation of the new parts.

Before:

After:

"Rookie makes Rookie Mistake"

The eagle-eyed among you already see why my office smelled like shit all day last Saturday. Of course, tantalums don't note polarity the same way any electrolytic I've dealt with has. So we installed them all backwards.

I know I have seen at least one person mention that while doing a recap and replacing electrolytics with tantalums. In fact, in the box from the company we ordered the replacements from:

So it's not like there weren't ample people trying to get this information into my head. Oh well, happens. Here's the before & after, after the second recap:

I also took the cardboard shield off the high voltage board and saw sticky burnt electrolyte gack on the back of the board. That gack was the smell that took this machine beyond just "nicotine soaked" when you turned it on.

We've removed the high voltage board and will re-cap that in Part 3.

I'm in no position to recommend the hot air station we got, but it was just "not quite the cheapest one on Amazon". Came with some extras like a pair of side cutters and a couple pairs of tweezers, so that was helpful.

PiST

Music: 

Peter Murphy - The Sweetest Drop

*Skip to the RetroPie customization stuff*

Like every other moderately Vintage / Retro Computing person,
not to mention my whole job being what it is, I immediately bought one of those
12" IPS 16:9 Eyoyo monitors when I started seeing them pop up on some YouTube channels. Thing works great as a bench monitor, but it's kind of a weird size for use with 1980s OSes that expect 4:3. I found that Eyoyo also makes a 4:3 12" 800x600 monitor with all the same inputs so I grabbed one. Since the Atari branded monitors for the ST were 12", and I never saw any of these machines on anything much bigger than a 13" TV back in the day, this looks pretty much exactly as I remember and the correct aspect ratio makes everything feel "bigger" in the right way.

The Pi 3 seems to be completely sufficient for emulating a stock 8Mhz 68000, it just needs enough power, swapping a 750ma power supply for 2.5A made a huge speed difference in emulation. I'm not trying to make this a "modern" experience like PiMiga or anything that requires any more horespower. For software, I started with RetroPie for their package management and the fact that they've already done the work of building all their packages to run from the command line with SDL/framebuffer, plus the ease of tweaking things like the boot splash screen, etc.

Aside from that, it's really just Hatari and Amiberry. I found a 1GB ACSI disk image for the ST which is split into thirds and had a bunch of preloaded software. I've not added anything to it yet, but apparently the hero at 8bitchip has also archived over 1500 ST games and has patched them to run from a hard disk so I won't need to sort through a bunch of disk images which is great. I already spotted Oxyd in the list.

That all makes me want to get NeoDesk running, which I gather is possible though it didn't immediately work in the 5 minutes I had to spend on it. Like I said, for this machine I'm not interested in running a "modern" take like PiMiga. But "nostalgia", well, while I'd certainly love to have original ST or Amiga hardware, I really am more nostalgic for the content and getting in front of Vroom or Nebulus for 10 minutes every 2 months, and it's awesome that it's using the same desktop I spent so much time in front of.

The little boot menu I wrote just replaces the RetroPie autostart.sh file at /opt/retropie/configs/all/ with one that shows the user a menu to select the boot OS or shutdown. Windows 3.11 is a menu option, that's kind of TBD. DosBox is installed but I haven't done the full Windows install yet but it'll be fun to play Solitaire on this thing.


Little tweaks I made to RetroPie

I used RetroPie as my base rather than regular Raspbian because of their great packaging and basic customization tools. I just installed Hatari and Amiberry from the retropie_setup installer and they worked immediately at the command line. The retropie_setup tool also lets you swap out the default boot splash screen. I was expecting to just find the location of the file and swap in an Atari Fuji logo and be done with it. But they've built the tool into their setup utility, and even let you assign an MP4 so I was able to use an animated rainbow Fuji logo so it just looks awesome.

I made one edit to /boot/cmdline.txt to suppress the bootup log output, so cmdline.txt looks like this now:

console=serial0,115200 console=tty1 root=PARTUUID=8ee2ea28-02 rootfstype=ext4 fsck.repair=yes rootwait loglevel=3 quiet consoleblank=0 plymouth.enable=0

I copied /opt/retropie/configs/all/autostart.sh out of the way and replaced it with:

#!/bin/bash

/home/pi/bin/menu

That's pointing to the boot menu screen. It's really simple but really what am I trying to do here? I did add a countdown timer so it will automatically boot to an ST desktop after 20 seconds:


#!/bin/bash
# /opt/retropie/configs/all/autostart.sh

clear
echo "POMPEY PIRATES" | sed -e :a -e "s/^.\{1,$(tput cols)\}$/ & /;ta" | tr -d '\n' | head -c $(tput cols)
echo ""
echo ""
echo "Press '1' For Atari ST"
echo "Press '2' For Amiga"
echo "Press '3' For Windows 3.11"
echo "Press '9' For Bash Shell"
echo "Press '0' For Shutdown"
echo "Press 'T' For Trainer"
echo ""
echo ""

msg="Booting Atari ST in"
tput cup 12 0
echo -n "$msg"

l=${#msg}

l=$(( l+1 ))

for i in {15..01}
do
tput cup 12 $l
echo -n "$i Seconds"

read -t 1 -n 1 system 2>/dev/null

if [ "$system" = "1" ]
then
/opt/retropie/emulators/hatari/bin/hatari --timer-d 0 && reset; /home/pi/bin/menu
elif [ "$system" = "2" ]
then
/opt/retropie/emulators/amiberry/amiberry.sh && reset; /home/pi/bin/menu
elif [ "$system" = "9" ]
then
exit 0
elif [ "$system" = "0" ]
then
sudo shutdown -h now
fi

done

/opt/retropie/emulators/hatari/bin/hatari --timer-d 0 && reset; /home/pi/bin/menu


To-Do

  • I'll probably install Windows and Mini vMac just to do it
  • Add ST High Res mode
  • May add a timer to the menu to boot to the ST after some number of seconds just to make it more immersive.
  • Add a "POMPEY PIRATES" at the top and "PRESS 'T' FOR TRAINER" at the bottom for authenticity

    Caching Password passer

    Similar to the RDP Launcher, I occasionally need to grab passwords that I use all the time from KeePassXC to paste into various forms or prompts. Basically anything I use more than once per day, I have defined in this script for quick access. I don't want to be able to remember these, and I also don't want to have to interact with the password manager UI if I'm in a shell.

    Another note for myself for later, and boy this is dumb.

    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.

    The launcher for that looks like:

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

    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
    GenericName[en_US]=
    GenericName=windowsmachine
    Icon=remmina
    MimeType=
    Name[en_US]=
    Name=windowsmachine

    Type=Application
    X-DBUS-ServiceName=windowsmachine
    X-DBUS-StartupType=
    X-KDE-SubstituteUID=false
    X-KDE-Username=

    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.
